Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated building steel structure construction, and more specifically to a positioning connection device and a building module device. Background Art

[0002] Box-type modular buildings are a type of prefabricated steel structure buildings. Since its building modules can be pre-installed in the factory and stacked on the project site to complete the construction project, box-type modular buildings have the characteristics of high prefabrication, small workload on the construction site and short project period. Among them, the manufacturing deviation of building modules and the stacking deviation on the project site have always been important factors restricting the development of box-type modular buildings. At present, because the interior decoration, external curtain walls and connection points of construction projects have high requirements for installation accuracy, how to improve the positioning accuracy between building modules in construction projects has become an urgent problem to be solved in box-type modular buildings. However, due to the technical limitations of the current building module positioning structure, the positioning structure in the prior art is difficult to achieve the positioning accuracy that meets the requirements of the construction project.

[0003] In the prior art, although the influence of stacking deviation on the positioning accuracy of building modules can be reduced, the influence of manufacturing deviation on the positioning accuracy of building modules cannot be avoided. For example, the positioning structure between building modules in the "Automatic Positioning System for Stacking Modular Building Modules and Connection Method thereof" with publication number CN104179254A can reduce the influence of stacking deviation on the positioning accuracy of building modules when stacking building modules. Figure 1 As shown, the building module positioning system in the prior art includes four connectors (at least one bidirectional positioning connector 1, at least one unidirectional positioning-unidirectional guiding connector 2 and at least one double-slope guiding connector 3) fixedly connected to the bottom of the upper building module, and four square tubes fixedly connected to the top of the lower building module and arranged corresponding to the four connectors. The positioning and stacking of the upper and lower building modules are completed by the cooperation between the four connectors at the bottom of the upper building module and the four square tubes at the top of the lower building module.

[0004] It can be seen from the principle of the building module positioning structure of the prior art that since the four connectors and the four square tubes need to be fixedly connected to the building module, and their positioning accuracy is the same as the manufacturing accuracy of the building module. Therefore, the building module positioning structure of the prior art cannot avoid the influence of the manufacturing deviation of the building module on the positioning accuracy of the building module. In addition, the current building module is mainly composed of welded steel structure and has a large specification, which makes the manufacturing accuracy of the building module become the main factor affecting the positioning accuracy of the building module. Therefore, if the positioning accuracy of the building module needs to be improved in the prior art, it must cost a lot to improve the manufacturing accuracy of the building module.

[0005] Therefore, a positioning connection device and a building module device are needed to at least partially solve the problems existing in the prior art. Summary of the invention

[0006] A series of simplified concepts are introduced in the Summary of the Invention, which will be further described in detail in the Detailed Description of the Invention.

[0021] There are a plurality of bottom reference plates, and bottom surfaces of the plurality of bottom reference plates are coplanar to form a bottom reference plane.

[0022] Thereby, it is ensured that the top surfaces of the top reference plate and the bottom reference plate serve as the top reference plane and the bottom reference plane of the building module.

[0023] Preferably, the building module is provided with a top corner fitting, and the corner of the top base plate has a notch, and the notch is used to match the top corner fitting to accommodate the top corner fitting; and / or

[0024] The building module is provided with a bottom corner piece, and the corner of the bottom reference plate has a notch, and the notch is used to match the bottom corner piece to accommodate the bottom corner piece.

[0027] The building module is provided with a bottom corner piece, and the bottom surface of the bottom reference plate is lower than the bottom surface of the bottom corner piece.

[0032] The present invention also provides a positioning and connecting device for a building module, the positioning and connecting device comprising:

[0033] a top reference plate, the top reference plate being provided with a top positioning hole, the top reference plate being used to be connected to the top of the building module; and

[0034] A bottom reference plate, the bottom reference plate being provided with a bottom positioning hole, the bottom reference plate being used to be connected to the bottom of the building module,

[0035] Among them, the top reference plate is positioned to the top predetermined position through the top positioning hole, and the bottom reference plate is positioned to the bottom predetermined position through the bottom positioning hole.

[0036] According to the positioning and connecting device of the present invention, the top reference plate is positioned to the top predetermined position through the top positioning hole, and the bottom reference plate is positioned to the bottom predetermined position through the bottom positioning hole. The top predetermined position and the bottom predetermined position have the same horizontal coordinate position relative to the predetermined reference point and are arranged vertically opposite to each other. In this way, the positioning accuracy is high, the operation is simple, and the building module structure is compact, which can be used to reduce the influence of manufacturing deviation and stacking error on the positioning accuracy of the building module and meet the requirements of fast, simple and high-precision stacking and connection of the building module at the project site.

[0037] Preferably, there are multiple top reference plates, each of which is provided with a positioning cone, and the top positioning hole of each top reference plate includes a positioning cone positioning hole arranged at the top of the positioning cone, and a top positioning small hole arranged on the top reference plate, and the positioning cone is used to extend through the bottom reference plate of another positioning connection device.

[0046] Therefore, since the diameter of the bottom positioning hole of the third bottom reference plate is larger than the diameter of the bottom positioning hole of the first bottom reference plate, there is more room for movement when stacking and positioning building modules with manufacturing deviations, so that each bottom reference plate can be positioned to the predetermined bottom position to ensure positioning accuracy.

[0047] Preferably, the bottom reference plate further comprises a bottom connection hole, and the top reference plate further comprises a top connection hole;

[0108] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0109] In order to fully understand the present invention, a detailed structure will be presented in the following description to illustrate the present invention. Obviously, the implementation of the present invention is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other embodiments and should not be construed as being limited to the embodiments presented here.

[0112] Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings, which illustrate representative embodiments of the present invention and do not limit the present invention.

[0113] like Figures 2 to 4 As shown, the present invention provides a building module device. The building module device includes a positioning connection device 100 and a building module 200. The building module 200 can be a container, or a building or product of other structures. The positioning connection device 100 can be used to connect two building modules stacked up and down, and can also be used to connect two layers of building modules, such as two upper building modules and two lower building modules, and can also be used to connect the building module to the ground.

[0114] The positioning connection device 100 includes a top reference plate 110 and a bottom reference plate 120. The top reference plate 110 is used to connect to the top of the building module 200 (refer to Fig.15 ), the bottom reference plate 120 is used to connect to the bottom of the building module 200. Although the illustrated embodiment only shows a bottom corner of the building module 200, Fig.13 and Fig.15 It can be understood that the top reference plates 110 are respectively arranged at the four top corners of the building module 200, and the bottom reference plates 120 are respectively arranged at the four bottom corners of the building module 200. The four top reference plates 110 correspond to the four bottom reference plates 120 one by one.

[0115] The positions of the top reference plate 110 and the bottom reference plate 120 can be defined as the top predetermined position and the bottom predetermined position, respectively. The top predetermined position and the bottom predetermined position of the corresponding top reference plate 110 and the bottom reference plate 120 have the same horizontal coordinate position relative to the predetermined reference point and are arranged vertically opposite to each other. Further, the projections of the top reference plate 110 and the bottom reference plate 120 along the height direction of the building module 200 coincide. It can be understood that the top predetermined position and the bottom predetermined position can be understood as the determined position of the building module 200, which will not deviate due to the manufacturing deviation of the building module 200 itself, so that the building module 200 can be accurately positioned and connected.

[0116] The top reference plate 110 and the bottom reference plate 120 are described in detail below.

[0117] like Figures 5 to 7 As shown, the top reference plate 110 is constructed as a flat plate so that it can be placed horizontally at the top predetermined position. The top reference plate 110 is provided with a top positioning hole that is recessed downward to facilitate the placement of a laser reflector, so that the top reference plate 110 can be positioned to the top predetermined position of the building module 200 through the top positioning hole. In this embodiment, the top reference plate 110 is provided with a positioning cone 111 and a top positioning hole 113. The positioning cone 111 protrudes upward to extend through the bottom reference plate 120 of another building module device. The top of the positioning cone 111 is provided with a positioning cone positioning hole 112. It can be understood that another building module device here is stacked on top of the building module 200.

[0118] The positioning cone positioning hole 112 and the top positioning hole 113 belong to the top positioning hole. In other words, the top positioning hole includes the positioning cone positioning hole 112 and the top positioning hole 113. The positioning cone positioning hole 112 and the top positioning hole 113 cooperate to position the top reference plate 110. Optionally, the top positioning hole 113 can be arranged away from the positioning cone 111.

[0119] It should be noted that the positions of the positioning cone positioning hole 112 and the top positioning hole 113 can be understood as the positioning points selected for positioning the top reference plate 110. The top reference plate 110 can be accurately positioned with the help of these two top positioning holes. If necessary and / or desired, the top surface of the positioning cone 111 and the top positioning hole 113 can be configured into other suitable shapes to facilitate the placement of the laser reflector.

[0120] Specifically, Figure 7 As shown, the positioning cone 111 includes a cone head 114, a cone body 115 and a cone bottom 116. The cone head 114 is a cone, which can play a guiding role in the process of aligning with the bottom reference plate 120 of another building module device. The cone body 115 is a cylinder. As a result, the positioning cone 111 can be uniformly stressed, so that the top reference plate 110 is more firmly connected to the building module 200. Of course, the cone head 114 can also be a square cone. The positioning cone positioning hole 112 is set at the top of the cone head 114. The cone bottom 116 is used to connect to the top reference plate 110.

[0121] The bottom of the cone head 114 transitions with the top of the cone 115 in an arc. The diameter of the bottom of the cone head 114 is not greater than the diameter of the top of the cone 115. The cone 115 has a positioning cylindrical surface. The positioning cylindrical surfaces are continuously arranged circumferentially along the central axis of the cone 115. The center of the positioning cone positioning hole 112 coincides with the central axis of the cone 115. The cone bottom 116 is a cylinder, which has a thread. The thread is continuously surrounded circumferentially along the central axis of the cone bottom 116. The central axis of the cone bottom 116 coincides with the central axis of the cone 115. The center line of the positioning cone positioning hole 112, the central axis of the cone head 114, the central axis of the cone 115 and the central axis of the cone bottom 116 all coincide, which is the central axis of the positioning cone 111. The top reference plate 110 is provided with a top positioning large hole 117, and the cone bottom 116 is threadedly connected to the top positioning large hole 117. Of course, the conical bottom 116 may not be provided with threads, but may be connected to the top reference plate 110 (top positioning large hole 117) by welding or other suitable methods.

[0122] Preferably, the central axis of the positioning cone 111 coincides with the central line of the top positioning large hole 117. Therefore, the positioning accuracy of the top reference plate 110 on the building module 200 can be guaranteed.

[0123] Further, refer to Figure 5 and Figure 6 The top reference plate 110 may also be provided with a top connection hole 118 for a fastener 170 to pass through so as to connect the top reference plate 110 to a bottom reference plate of another building module device.

[0124] Optionally, the cone 115 may be provided with an operating hole, which may be a through hole, which can be connected to an operating member (e.g., an operating rod). When the positioning cone 111 is threadedly connected to the top positioning large hole 117, the operator can operate the operating member to rotate it around the central axis of the positioning cone 111, and the positioning cone 111 also rotates accordingly. This makes it unnecessary for the operator to directly operate the positioning cone 111.

[0125] In addition, the illustrated embodiment exemplarily shows that the top reference plate 110 is a rectangular plate. Of course, the top reference plate 110 can also be any one of a square plate, a circular plate and a triangular plate. In this embodiment, preferably, the above-mentioned four top reference plates 110 have the same structure. If necessary and / or desired, the shape of the four top reference plates 110 may not be limited to the same shape, and they may be different shapes respectively. The corners of the top reference plate 110 may be formed with chamfers to prevent the operator from being injured by moving the top reference plate 110.

[0126] Optionally, in this embodiment, a top corner piece is provided at the top corner of the building module 200. A top base plate notch 119 may be provided at the corner of the top base plate 110 to match the top corner piece to accommodate the top corner piece (refer to Figure 4 The shape of the top base plate notch 119 is adapted to the shape of the top corner piece of the building module 200 to facilitate the installation of the top base plate 110 .

[0127] like Figure 4 As shown, the bottom reference plate 120 is constructed as a flat plate so that it can be placed horizontally at a predetermined bottom position. The bottom reference plate 120 is provided with a bottom positioning hole so that the bottom reference plate 120 can be positioned to the predetermined bottom position through the bottom positioning hole. The bottom positioning hole includes a bottom positioning large hole 121 and a bottom positioning small hole 122. The bottom positioning large hole 121 is used to fit with the positioning cone of another building module device or the tooling cone 331 (described in detail below) set on the tooling table 320. The bottom positioning small hole 122 is used to place a laser reflector. It can be understood that another building module device here is stacked below the building module 200.

[0128] Further, the bottom positioning hole 121 may correspond to the positioning cone at the top positioning hole of the top reference plate of another building module device (here mainly refers to the position correspondence). The positioning cone 111 may pass through the bottom positioning hole 121 to facilitate the connection of the bottom reference plate 120 with the top reference plate 110. In addition, the bottom positioning hole 121 may also correspond to the tooling cone 331 of the tooling table 320. The tooling cone 331 may pass through the bottom positioning hole 121 to facilitate the positioning of the bottom reference plate 120 with the aid of the tooling table 320 before the bottom reference plate 120 is connected to the building module 200.

[0129] It should be noted that the position of the bottom positioning holes 122 can be understood as the positioning points selected for positioning the bottom reference plate 120. The bottom reference plate 120 can be accurately positioned with the help of these two bottom positioning holes. If necessary and / or desired, the bottom positioning holes 122 can be configured into other suitable shapes to facilitate the placement of the laser reflector.

[0130] Further, the bottom reference plate 120 may also be provided with a bottom connection hole 123 for fastener 170 to pass through to connect the bottom reference plate 120 with the top reference plate of another building module device. Specifically, the bottom connection hole 123 corresponds to the top connection hole of the top reference plate of another building module device.

[0131] Preferably, the bottom positioning large hole 121 is a through hole, which can be arranged close to the bottom reference plate notch 124. The bottom positioning small hole 122 is a through hole, which can be arranged away from the positioning cone 111. The bottom positioning small hole 122 can be a circular hole or a hole of other suitable shapes. In the illustrated embodiment, the bottom positioning small hole 122 is a through hole, and of course it can also be other suitable holes such as blind holes. The bottom connecting hole 123 can be arranged between the bottom positioning large hole 121 and the bottom positioning small hole 122. The aperture of the bottom positioning large hole 121 can be larger than the aperture of the bottom connecting hole 123. The aperture of the bottom connecting hole 123 can be larger than the aperture of the bottom positioning small hole 122.

[0132] In addition, the illustrated embodiment exemplarily shows that the bottom reference plate 120 is configured as a rectangular plate. Of course, the bottom reference plate 120 can also be any one of a square plate, a circular plate and a triangular plate. In the present embodiment, preferably, the above-mentioned four bottom reference plates 120 have the same shape. If necessary and / or desired, the shape of the four bottom reference plates 120 may also not be limited to the same shape, and they may be different shapes respectively. The corners of the bottom reference plate 120 may be formed with chamfers to prevent the operator from being injured by moving the bottom reference plate 120.

[0133] Optionally, in this embodiment, a bottom corner piece is provided at the bottom corner of the building module 200. A bottom reference plate notch 124 may be provided at the corner of the bottom reference plate 120 to match the bottom corner piece to accommodate the bottom corner piece (refer to Figure 4 ). The shape of the bottom reference plate notch 124 is adapted to the shape of the bottom corner piece of the building module 200 to facilitate the installation of the bottom reference plate 120.

[0134] Specifically, Figures 8 to 10 as well as Fig.13 As shown, the bottom reference plate 120 includes a first bottom reference plate 130, a second bottom reference plate 140, a third bottom reference plate 150, and a fourth bottom reference plate 160 (see FIG. Fig.13). The structures / configurations of the first bottom reference plate 130, the second bottom reference plate 140, the third bottom reference plate 150 and the fourth bottom reference plate 160 are substantially the same as those of the above-mentioned bottom reference plate 120, except for the shape of the bottom positioning large hole 121. For the sake of brevity, the same parts are not repeated.

[0135] like Figure 8 As shown, the first bottom reference plate 130 includes a first bottom positioning large hole 131, a first bottom connecting hole 133 and a first bottom positioning small hole 132. The first bottom positioning large hole 131 and the first bottom positioning small hole 132 cooperate to position the first bottom reference plate 130.

[0136] The first bottom positioning hole 131 is a round hole and is clearance-matched with a positioning cone or a tooling cone of another building module device, and the matching tolerance is between ±0.5mm and ±1mm.

[0137] like Fig. 9 As shown, the second bottom reference plate 140 includes a second bottom positioning large hole 141, a second bottom connecting hole 143, and a second bottom positioning small hole 142. The second bottom positioning large hole 141 and the second bottom positioning small hole 142 cooperate to position the second bottom reference plate 140.

[0138] The second bottom positioning hole 141 is a waist-shaped hole. The width of the waist-shaped hole is approximately equal to the diameter of the first bottom positioning hole 131. The length of the waist-shaped hole is not less than the diameter of the third bottom positioning hole 151 (described in detail below). The second bottom positioning hole 141 is clearance-matched with the positioning cone or tooling cone 331 of another building module device, and the hole wall of the waist-shaped hole in the hole width direction is clearance-matched with the positioning cone 111, and the matching tolerance is between ±0.5mm and ±1mm.

[0139] like Fig.10 As shown, the third bottom reference plate 150 includes a third bottom positioning large hole 151, a third bottom connecting hole 153 and a third bottom positioning small hole 152. The third bottom positioning large hole 151 and the third bottom positioning small hole 152 cooperate to position the third bottom reference plate 150.

[0140] The third bottom positioning hole 151 is a circular hole. The diameter of the third bottom positioning hole 151 is larger than the diameter of the first bottom positioning hole 131. Since the diameter of the third bottom positioning hole 151 is larger than the diameter of the first bottom positioning hole 131, the matching tolerance between the third bottom positioning hole 151 and the positioning cone 111 is not limited.

[0141] refer to Fig.13 The fourth bottom reference plate 160 includes a fourth bottom positioning large hole, a fourth bottom connecting hole 163 and a fourth bottom positioning small hole. The fourth bottom positioning large hole and the fourth bottom positioning small hole cooperate to position the fourth bottom reference plate 160.

[0142] Optionally, the structure of the fourth bottom reference plate 160 may be the same as the structure of the third bottom reference plate 150. If needed and / or desired, the structure of the fourth bottom reference plate 160 may be configured to be the same as the structure of the first bottom reference plate 130, or to be configured to be the same as the structure of the second bottom reference plate 140.

[0143] In this embodiment, the first bottom reference plate 130 and the second bottom reference plate 140 are arranged along the length direction of the building module 200, the third bottom reference plate 150 and the first bottom reference plate 130 are arranged along the width direction of the building module 200, and the fourth bottom reference plate 160 and the first bottom reference plate 130 are arranged along the diagonal direction of the building module 200.

[0144] The top reference plate 110 can be welded to the top of the building module 200 or connected by fasteners. The bottom reference plate 120 can be welded to the bottom of the building module 200 or connected by fasteners. The top surfaces of the above four top reference plates 110 are coplanar to form a top reference plane. The bottom surfaces of the above four bottom reference plates 120 are coplanar to form a bottom reference plane. The top reference plane is parallel to the bottom reference plane. In this way, it can be ensured that the building module 200 is based on the top reference plate 110 and the bottom reference plate 120 in the subsequent stacking process, thereby avoiding positioning deviation caused by the manufacturing deviation of the building module 200 itself.

[0145] Further, the top corner of the building module 200 may be provided with a frame structure so that the top reference plate 110 can be installed at the frame structure. The positioning and connecting device 100 may also include a plurality of top gaskets 101. The top gasket 101 is provided between the top reference plate 110 and the building module 200, that is, between the top reference plate 110 and the frame structure, to fill the gap between the top reference plate 110 and the top of the building module 200. The upper and lower surfaces of the top gasket 101 are respectively in contact with the top reference plate 110 and the building module 200, so that the top surfaces of the four top reference plates 110 can be kept coplanar to form a top reference plane. Considering that the top surface of the building module 200 may be uneven, the thickness of the top gasket 101 may be different so that it can be arranged reasonably so that the four top reference plates 110 can be kept coplanar. And in the process of positioning the top reference plate 110 described below, the top reference plate 110 can be leveled with the help of the top gasket 101. Optionally, the top gasket 101 may be welded to the building module 200 together with the top reference plate 110 .

[0146] Alternatively, if Fig.11As shown, in order to facilitate the operator to operate the top gasket 101, the top gasket 101 has a flange 103. When the top reference plate 110 is placed above the top gasket 101, the flange 103 does not interfere with the top reference plate 110. When the top reference plate 110 is placed above a plurality of top gaskets 101, the plurality of top gaskets 101 are arranged around the edge of the top reference plate 110, and the flanges 103 of the plurality of top gaskets 101 are also arranged around the edge of the top reference plate 110, so that the operator can insert the top gasket 101 between the top reference plate 110 and the building module 200 by operating the flange 103.

[0147] Furthermore, a frame structure may be provided at the bottom corner of the building module 200 so that the bottom reference plate 120 can be mounted to the frame structure. Figure 4 , the positioning and connecting device 100 may also include a plurality of bottom gaskets 102. The bottom gasket 102 is arranged between the bottom reference plate 120 and the building module 200, that is, between the bottom reference plate 120 and the frame structure, to fill the gap between the bottom reference plate 120 and the bottom of the building module 200. The upper and lower surfaces of the top gasket 101 are respectively in contact with the top reference plate 110 and the building module 200, so that the bottom surfaces of the four bottom reference plates 120 can be kept coplanar to form a bottom reference plane. Considering that the bottom surface of the building module 200 may be uneven, the thickness of the bottom gasket 102 may be different, so that it is convenient to arrange it reasonably, so that the four bottom reference plates 120 can be kept coplanar. Optionally, the bottom gasket 102 can be welded to the building module 200 together with the bottom reference plate 120. The bottom gasket 102 has the same structure as the above-mentioned top gasket 101, which will not be repeated here.

[0148] The following describes a building module arrangement stacked one above the other and / or arranged side by side horizontally.

[0149] like Figures 2 to 4 As shown, the illustrated embodiment exemplarily shows four building module devices, namely two upper building module devices and two lower building module devices. The building module devices of each layer are arranged side by side, and the building modules 200 in the building module devices stacked up and down are connected by the positioning connection device 100. Specifically, the building module 200 includes a first building module 210 and a second building module 220 arranged side by side, and a third building module 230 and a fourth building module 240 arranged side by side. The first building module 210 is stacked on top of the third building module 230, and the second building module 220 is stacked on top of the fourth building module 240. In other words, the first building module 210 and the second building module 220 are upper building modules, and the third building module 230 and the fourth building module 240 are lower building modules. Although only the corners of each building module are shown in the figure, it can be understood that the top and bottom of each building module are respectively connected to the top reference plate 110 and the bottom reference plate 120.

[0150] The first building module bottom reference plate 120a corresponds to the third building module top reference plate 110a in vertical correspondence. The second building module bottom reference plate 120b corresponds to the fourth building module top reference plate 110b in vertical correspondence. The bottom surface of the first building module bottom reference plate 120a and the bottom surface of the second building module bottom reference plate 120b are coplanar, that is, on the same bottom reference plane. The top surface of the third building module top reference plate 110a and the top surface of the fourth building module top reference plate 110b are coplanar, that is, on the same top reference plane.

[0151] To facilitate connecting the side-by-side building module devices together, further, as Figure 4 As shown, a horizontal connector 180 is also included. The horizontal connector 180 is preferably in the shape of a plate. The horizontal connector 180 is disposed at the corners of the building modules arranged side by side, and is disposed between the upper building module device and the lower building module device. In other words, the horizontal connector 180 is disposed between the bottom reference plate 120 of the upper building module (the first and second building modules 210, 220) and the top reference plate 110 of the lower building module (the third and fourth building modules 230, 240). Specifically, the horizontal connector 180 is parallel to and abuts against the bottom reference plate 120a of the first building module, the bottom reference plate 120b of the second building module, the top reference plate 110a of the third building module, and the top reference plate 110b of the fourth building module. With the help of the horizontal connector 180, the building module device can be connected in the horizontal direction, and the connection strength of the positioning connection device 100 can be strengthened. The horizontal connector 180 can overlap with each reference plate at the corner of each building module. Specifically, the horizontal connection member 180 may overlap the first and second building module bottom reference plates 120a and 120b, and the third and fourth building module top reference plates 110a and 110b.

[0152] The horizontal connector 180 is provided with symmetrically arranged horizontal connector positioning holes and symmetrically arranged horizontal connector connecting holes. The horizontal connector positioning holes are used for the positioning cone of the top base plate of the lower building module to pass through. The horizontal connector connecting holes are used for the fastener 170 to pass through.

[0153] In the illustrated embodiment, referring to Figure 4, the horizontal connector positioning holes include a first horizontal connector positioning hole 181 and a second horizontal connector positioning hole 182. The horizontal connector connection holes include a first horizontal connector connection hole 183 and a second horizontal connector connection hole 184. The following description is made by taking the first horizontal connector positioning hole 181 and the first horizontal connector connection hole 183 as examples. The first horizontal connector positioning hole 181 corresponds to the positioning cone 111a of the top reference plate 110a of the third building module and the bottom positioning large hole 121a of the bottom reference plate 120a of the first building module. The first horizontal connector connection hole 183 corresponds to the top connection hole 118a of the top reference plate 110a of the third building module and the bottom connection hole 123a of the bottom reference plate 120a of the first building module. The first horizontal connector positioning hole 181 is clearance-matched with the positioning cylindrical surface of the positioning cone 111a of the top reference plate 110a of the third building module. As described above, the positioning cone 111a of the top reference plate 110a of the third building module is loosely matched with the bottom positioning large hole 121a of the bottom reference plate 120a of the first building module.

[0154] When the first building module 210 and the third building module 230 are stacked up and down, the positioning cone 111a of the top reference plate 110a of the third building module can sequentially pass through the first horizontal connector positioning hole 181 and the bottom positioning large hole 121a of the bottom reference plate 120a of the first building module. The fastener 170 can sequentially pass through the bottom connection hole 123a of the bottom reference plate 120a of the first building module, the first horizontal connector connection hole 183 and the top connection hole 118a of the top reference plate 110a of the third building module from top to bottom, and connect them together.

[0155] More specifically, the center axis of the positioning cone 111a of the top reference plate 110a of the third building module, the center of the positioning hole 181 of the first horizontal connector, and the center line of the bottom positioning large hole 121a of the bottom reference plate 120a of the first building module coincide. The center of the top connection hole 118a of the top reference plate 110a of the third building module, the center of the connection hole of the first horizontal connector, and the center line of the bottom connection hole 123a of the bottom reference plate 120a of the first building module coincide.

[0156] Similarly, when the second building module 220 and the fourth building module 240 are stacked up and down, the positioning cone 111b of the top reference plate 110b of the fourth building module can sequentially pass through the second horizontal connector positioning hole 182 and the bottom positioning large hole 121b of the bottom reference plate 120b of the second building module. The fastener 170 can sequentially pass through the bottom connection hole 123b of the bottom reference plate 120b of the second building module, the second horizontal connector connection hole 184 and the top connection hole 118b of the top reference plate 110b of the fourth building module from top to bottom, and connect them together. In this way, the second building module 220 and the fourth building module 240 can be connected together.

[0157] Therefore, by means of the top reference plate 110, the bottom reference plate 120 and the horizontal connector 180, the corners of adjacent building modules can be connected together, thereby achieving the connection of the above four building modules.

[0158] Alternatively, if Figures 2 to 4 As shown, the fastener 170 includes a bolt 171, a nut 172, and a stopper 173 that accommodates and limits the position of the nut 172. Specifically, the stopper 173 is disposed below the top connection hole of the top reference plate of the lower building module (e.g., the top reference plate 110a of the third building module), and the stopper 173 is fixedly connected to the top reference plate of the lower building module by welding or threaded connection. Fig.12 As shown, the stopper 173 has a main body 175 and a Z-shaped bending structure 176, and there are three bending structures 176. The three bending structures 176 are arranged circumferentially at intervals along the main body 175 of the stopper 173, and the angle between any two of the three bending structures 176 is 120°. The nut 172 is arranged between the top reference plate of the lower building module and the stopper 173, so that the top reference plate of the lower building module and the stopper 173 limit the rotation of the nut 172 to prevent it from loosening and falling off. The main body of the stopper 173 can also be provided with a bolt through hole 177 to prevent the stopper 173 from interfering with the bolt 171. The nut 172 is preferably a hexagonal nut. The fastener also includes a bolt washer 174 to reduce the wear of the reference plate during the tightening process of the bolt 171 and to strengthen the strength of the bolt connection.

[0159] The corners of the building module of this embodiment can be provided with top corner fittings and bottom corner fittings (refer to Figure 4 ), the top and bottom corner fittings play the role of transmitting various forces during the lifting, transportation, fixing and stacking of building modules, and can also protect the building modules.

[0160] In order to ensure that the corresponding top reference plates and bottom reference plates of the upper building module devices and the lower building module devices contact first during the stacking process, it is further preferred that the top surface of the top reference plate of the lower building module (for example, the bottom reference plate of the third building module) is higher than the top surface of the top corner piece of the lower building module (the top corner piece of the third building module), and the bottom surface of the bottom reference plate of the upper building module (for example, the bottom reference plate of the first building module) is lower than the bottom surface of the bottom corner piece of the upper building module (the bottom corner piece of the first building module).

[0161] Since the corner of the building module is the main position for transferring load, when the top surface of the top base plate of the lower building module is higher than the top surface of the top corner piece of the lower building module, for example, taking the third building module 230 as an example, there will be a gap between the top corner piece of the third building module and the horizontal connecting piece 180, so that the top corner piece of the third building module cannot play the role of transferring load. Therefore, a top corner piece gasket 105 (refer to Figure 4 ). The top surface of the top corner piece gasket 105 is coplanar with the top surface of the top reference plate 110a of the third building module, so that the top corner piece gasket 105 can abut against the horizontal connector 180. Similarly, when the bottom surface of the bottom reference plate of the upper building module is lower than the bottom surface of the bottom corner piece of the upper building module, for example, taking the first building module 210 as an example, there will be a gap between the bottom corner piece of the first building module and the horizontal connector 180, so that the bottom corner piece of the first building module cannot play a role in transferring loads. Therefore, a bottom corner piece gasket 106 can be provided at the bottom corner piece of the first building module (refer to Figure 4 ). The bottom surface of the bottom corner piece gasket 106 is coplanar with the bottom surface of the first building module bottom reference plate 120a, so that the bottom corner piece gasket 106 can abut against the horizontal connecting piece 180.

[0162] In addition, in an embodiment not shown, when only the building modules stacked one above the other need to be connected, no horizontal connector is required, and only the bottom reference plate of the upper building module and the top reference plate of the lower building module are connected by fasteners. In this embodiment, the top corner gasket of the lower building module can abut against the bottom corner gasket of the upper building module.

[0163] In an embodiment not shown, the building module device can be connected to the ground. That is, the building module can be connected to the ground through the bottom reference plate. In this embodiment, the positioning connection device also includes a foundation positioning cone. The foundation positioning cone is arranged on the ground. The structure of the foundation positioning cone is roughly the same as the structure of the positioning cone in the above text, wherein the central axis of the cone head, cone body and cone bottom of the foundation positioning cone coincides. There can be multiple foundation positioning cones, and the positions of multiple foundation positioning cones can be positioned by a laser positioning instrument of the positioning connection system. Multiple foundation positioning cones correspond to the bottom reference plates of the building modules one by one respectively. The foundation positioning cone passes through the bottom positioning large hole of the bottom reference plate and extends upward. One of the positioning cylindrical surfaces of the foundation positioning cone can cooperate with the first bottom positioning large hole to limit the freedom of the building module in the horizontal direction. Another positioning cylindrical surface of the foundation positioning cone can cooperate with the hole wall of the waist-shaped hole along the hole width direction to limit the remaining rotational freedom of the building module in the horizontal direction.

[0164] The present invention further provides a positioning and connecting device 100, the structure of which is the same as that of the positioning and connecting device in the building module device, and for the sake of brevity, it will not be described in detail here.

[0165] According to another aspect of the present invention, a positioning system 300 is provided for positioning the positioning connection device 100 to a predetermined position corresponding to the building module 200 so as to connect the positioning connection device 100 (i.e., the top reference plate 110 and the bottom reference plate 120) to the building module 200.

[0166] like Fig.13 and Fig.15 As shown, the positioning system 300 includes a laser positioning instrument 310 and a tooling table 320. The laser positioning instrument 310 and the tooling table 320 cooperate to accurately locate the positions of the bottom reference plate 120 and the top reference plate 110 in the positioning connection device. Specifically, the laser positioning instrument 310 cooperates with the tooling table 320 to locate the bottom reference plate 120 to a predetermined bottom position (refer to Fig.13 When the building module 200 is placed on the workbench 320, that is, when the building module 200 is placed on the bottom reference plate 120 located at the bottom predetermined position, the laser positioning instrument 310 is used to position the top reference plate 110 to the top predetermined position (refer to Fig.15 ).

[0167] The laser positioning instrument 310 is a three-dimensional laser positioning instrument. The laser positioning instrument 310 is mounted on a high platform 311 outside the tooling table 320. The positioning system 300 also includes a laser reflector (not shown) matched with the laser positioning instrument 310 and a control device for receiving a signal from the laser positioning instrument 310. The laser reflector can be placed at a positioning point to be measured. The control device identifies the position of the positioning point in response to the signal of the laser positioning instrument 310. It can be understood that the laser positioning instrument 310, the laser reflector and the control device of this embodiment form a laser tracking measurement system.

[0168] It is easy for a person skilled in the art to understand that the laser positioning instrument 310 can be the origin of the positioning coordinate system, and the laser positioning instrument 310 can calculate the coordinate value of the position of the laser reflector in the positioning coordinate system through laser reflection and software. Therefore, a predetermined reference point can be selected in the positioning coordinate system covered by the laser positioning instrument 310 to facilitate positioning of the bottom reference plate 120 and the top reference plate 110.

[0169] like Fig.13As shown, the tooling table 320 is configured to support the bottom reference plate 120 and can move and adjust the position of the bottom reference plate 120. The tooling table 320 can be a stand. The tooling table 320 includes a support seat 330 and a guide rail 340. The guide rail 340 is arranged in the horizontal direction, and the support seat 330 is arranged on the guide rail 340 at intervals and is movable relative to the guide rail 340. Thus, the support seat 330 can be moved in the horizontal direction to adjust the position in the horizontal direction. The position of the support seat 330 in the vertical direction is adjustable. Optionally, the support seat 330 can be arranged on the guide rail 340 by a lifting assembly (not shown), thereby, the support seat 330 can be moved in the vertical direction by means of the lifting assembly to adjust the position in the vertical direction. It should be noted that the "adjustment of the position in the vertical direction" here includes not only adjusting the lifting position of the support seat 330 but also adjusting the angle (for example, relative to the horizontal direction) position of the support seat 330.

[0170] The support seat 330 is configured to support and position the bottom reference plate 120 of the positioning connection device. The top surface of the support seat 330 is a plane, and the top surface is used to abut against the bottom reference plate 120. Each of the support seats 330 is provided with a tooling cone 331 protruding upward. The tooling cone 331 is used to pass through the bottom reference plate 120 to define the position of the bottom reference plate 120. The structure of the tooling cone 331 is substantially the same as the structure of the positioning cone 111 described above. Specifically, as shown in FIG. Fig.14 As shown, the tooling cone 331 includes a cone head, a cone body and a cone bottom, and the cone bottom is fixedly connected to the support seat 330. The bottom of the cone head transitions with the cone body in an arc. The cone head can be constructed as a circular cone or a square cone to play a guiding role in the alignment process with the bottom positioning large hole 121 of the bottom reference plate 120.

[0171] The cone head of the tooling cone 331 is provided with a tooling cone positioning hole 332 which is recessed downwards, so as to facilitate the placement of the laser reflector. The center line of the tooling cone positioning hole 332 coincides with the center axis of the tooling cone 331. It should be noted that the position of the tooling cone positioning hole 332 can be understood as a positioning point selected for positioning the support seat 330. The support seat 330 can be accurately positioned with the aid of the tooling cone positioning hole 332. If necessary and / or desired, the top surface of the cone head can be configured into other suitable shapes to facilitate the placement of the laser reflector.

[0172] The cone of the tooling cone 331 can be constructed as a cylinder, which has a positioning cylindrical surface, and the positioning cylindrical surface is continuously arranged in the circumferential direction of the central axis of the cone. The central axes of the cone head, cone body and cone bottom of the tooling cone 331 all coincide with each other, which is the central axis of the tooling cone 331. The central axis of the tooling cone 331 in this embodiment extends in the vertical direction.

[0173] Optionally, in the illustrated embodiment, the support seat 330 may be provided with a support seat notch. The bottom reference plate notch 124 is substantially aligned with the support seat notch. The tooling cone 331 is arranged close to the support seat notch. In an embodiment not shown, the support seat 330 may not be provided with a support seat notch.

[0174] The illustrated embodiment exemplarily shows that the tooling platform 320 is configured to carry one building module 200 through the support base 330 and the bottom reference plate 120. Specifically, the support base 330 includes a first support base 333, a second support base 334, a third support base 335 and a fourth support base 336. The first support base 333 and the third support base 335 are arranged along the transverse direction D1 of the tooling platform 320. The first support base 333 and the fourth support base 336 are arranged diagonally. In the illustrated embodiment, the first bottom reference plate 130, the second bottom reference plate 140, the third bottom reference plate 150 and the fourth bottom reference plate 160 can be placed on the first support base 333, the second support base 334, the third support base 335 and the fourth support base 336 in sequence. The tooling cones 331 of the first support seat 333, the second support seat 334, the third support seat 335 and the fourth support seat 336 can respectively pass through the first bottom reference plate 130, the second bottom reference plate 140, the third bottom reference plate 150 and the fourth bottom reference plate 160 to limit their positions on the support seat 330.

[0175] In an embodiment not shown, the first bottom reference plate 130 can be placed on the first support seat 333, and the second bottom reference plate 140, the third bottom reference plate 150 and the fourth bottom reference plate 160 can be placed on the second support seat 334, the third support seat 335 and the fourth support seat 336 as needed.

[0176] Further, the guide rail 340 is arranged on the support frame. The guide rail 340 includes a first guide rail 341, a second guide rail 342 perpendicular to the first guide rail 341, and a third guide rail 343 parallel to the second guide rail 342. The second guide rail 342 is arranged on the first guide rail 341 and is movable relative to the first guide rail 341. At least two of the support seats 330 are arranged on the second guide rail 342. The third guide rail 343 is fixedly arranged, and at least two of the support seats 330 are arranged on the third guide rail 343. In the illustrated embodiment, the first support seat 333 and the second support seat 334 are arranged on the third guide rail 343. The third support seat 335 and the fourth support seat 336 are arranged on the second guide rail 342 so as to adjust the positions of the two support seats 330 along the longitudinal direction D2 of the tooling table 320 together. Each of the support seats 330 can freely adjust the position along the transverse direction D1 of the tooling table 320.

[0177] Optionally, the movement of the support seat 330 relative to the guide rail 340 is achieved by a control device, and the control device moves each of the support seats 330 in response to the laser positioning instrument 310, for example, the third support seat 335 disposed on the third guide rail 343 is moved, or the second support seat 334 and the fourth support seat 336 disposed on the second guide rail 342 are moved together along the first guide rail 341 by moving the second guide rail 342. Of course, the control device can also control the second support seat 334 and the fourth support seat 336 to move relative to the second guide rail 342. Of course, the movement of the support seat 330 can also be achieved by manual movement.

[0178] Optionally, the tooling cones 331 of the first support seat 333, the second support seat 334, the third support seat 335 and the fourth support seat 336 are of the same shape and can be configured to be adapted to the shape of the first bottom positioning large hole 131. When the first bottom reference plate 130 is placed on the first support seat 333, the matching tolerance between the tooling cone 331 of the first support seat 333 and the first bottom positioning large hole 131 is between ±0.5mm and ±1mm. The second bottom positioning large hole 141, the third bottom positioning large hole 151 and the fourth bottom positioning large hole have larger sizes relative to the first bottom positioning large hole 131 (see above), so that after each tooling cone 331 passes through the corresponding bottom reference plate, the second bottom reference plate 140, the third bottom reference plate 150 and the fourth bottom reference plate 160 can move horizontally around their respective tooling cones 331 as needed to adjust their respective horizontal positions. Optionally, in an embodiment where the second bottom positioning large hole 141 is a waist-shaped hole, when the second bottom reference plate 140 is placed on the second support seat 334, the fitting tolerance between the tooling cone 331 of the second support seat 334 and the hole wall of the waist-shaped hole along the hole width direction is between ±0.5mm and ±1mm.

[0179] Furthermore, the tooling table 320 further includes a positioning pin 351. The positioning pin 351 extends upward, and is used to extend into the bottom corner piece of the building module 200 when the building module 200 is placed on the tooling table 320. Specifically, the positioning pin 351 can extend into the bottom corner piece through the corner piece hole of the bottom corner piece. Thus, it can play a guiding role in the process of aligning and abutting the building module 200 with the bottom reference plate 120, and limit the freedom of the building module 200 in the horizontal direction. The positioning pin 351 is spaced apart from the corresponding support seat 330. Fig.13It is shown that the positioning pin 351 is arranged outside the first support seat 333 and is spaced apart from the first support seat 333. The positioning pin 351 is set at the support seat notch of the first support seat 333. The positioning pin 351 is fixedly set on the positioning pin base 352, and the positioning pin base 352 is spaced apart from the third guide rail 343 provided with the first support seat 333. Optionally, in an embodiment in which the support frame is fixedly set on the ground, the positioning pin base 352 can be fixedly set on the ground.

[0180] It should be noted that the directional terms mentioned herein, such as “outside”, “upward”, etc., are relative to the horizontally placed tooling table 320 . Among them, “outside” refers to the direction away from the tooling table 320 .

[0181] The tooling platform 320 further includes a limiting plate 353. The limiting plate 353 extends horizontally toward the corresponding support seat 330, and is used to abut against the bottom corner piece of the building module 200 when the building module 200 is placed on the tooling platform 320. Specifically, the limiting plate 353 can abut against the side surface of the bottom corner piece. Thus, it can play a further guiding role in the process of aligning the building module 200 with the bottom reference plate 120, and limit the rotational freedom of the building module 200 in the horizontal direction. The limiting plate 353 is spaced apart from the corresponding support seat 330. Fig.13 The limiting plate 353 is shown to be arranged outside the third support seat 335 and spaced apart from the third support seat 335. The limiting plate 353 is disposed on a limiting plate base 354, and the limiting plate base 354 is spaced apart from the second guide rail 342 on which the third support seat 335 is disposed. The limiting plate base 354 can move together with the second guide rail 342 to maintain the relative position of the limiting plate 353 and the third support seat 335 along the longitudinal direction D2 of the workbench 320.

[0182] Optionally, the tooling table 320 further includes an additional support seat 337. The additional support seat 337 is disposed between the first support seat 333 and the third support seat 335. The additional support seat 337 is disposed on the second guide rail 342 and is movable relative to the second guide rail 342. Fig.15 When the building module 200 is placed on the workbench 320 , the additional support seat 337 can support the building module 200 .

[0183] The present invention also provides a connection method for building modules, which enables the positioning connection device (top reference plate 110 and bottom reference plate 120) to be connected to the building module 200, so that adjacent building modules 200 can be connected through the positioning connection device 100.

[0184] The connection method includes the following steps:

[0185] Step S1: According to the cooperation between the laser positioning instrument 310 and the tooling table 320 , the support base 330 of the tooling table 320 is positioned to a position where the bottom reference plate 120 corresponds to a predetermined bottom position.

[0186] In step S1, the top surface of each of the support seats 330 can be leveled on the same horizontal plane according to the laser positioning instrument 310. It is understood that the top surface of each of the support seats 330 has the same horizontal coordinate relative to the predetermined reference point. Specifically, it can be determined whether the height coordinate values ​​of at least three points of each of the top surfaces of the support seats 330 are the same according to the signal reflected by the laser reflector placed on the top surface of the support seat 330, so as to adjust the position of the top surface of each of the support seats 330. Optionally, three to five points on the top surface of the support seat 330 can be selected to determine whether its top surface is horizontal.

[0187] In this embodiment, the top surface of the support base 330 can be leveled by adjusting the vertical position of the support base 330, so that the top surface of each of the support bases 330 can be leveled on the same horizontal plane. For example, the top surface of the support base 330 can be leveled first, that is, the top surface of the support base 330 is horizontal, and then the height of the support base 330 is adjusted by the lifting assembly so that the top surface of the support base 330 is at the same horizontal coordinate.

[0188] Further, in step S1, the support seat 330 after leveling can be positioned by the positioning point of the support seat 330 according to the laser positioning instrument 310. It can be understood that the "positioning point" is a fixed point selected on the support seat 330, and the positioning point moves together with the support seat 330. In this embodiment, the positioning point is selected at the tooling cone positioning hole 332. Specifically, a laser reflector can be placed at the tooling cone positioning hole 332, and the signal reflected by the laser reflector placed at the tooling cone positioning hole 332 is used to determine whether the positioning point at the tooling cone positioning hole 332 is located at the preset coordinate value, and the support seat 330 is moved to adjust the position of the positioning point relative to the laser positioning instrument 310. For example, when the positioning point deviates from the preset coordinate value, the position of the support seat 330 is moved in the horizontal direction, and when the positioning point is located at the preset coordinate value, the support seat 330 is stopped from moving. In this way, the positioning of the support seat 330 in the horizontal direction can be achieved. The above four support seats 330 can be positioned separately.

[0189] It is understood that the position of the support seat 330 in the horizontal direction is achieved by the control device moving the support seat 330 in response to the laser positioning instrument 310. In this embodiment, each of the support seats 330 can be moved separately to adjust its position on the corresponding guide rail 340, and the second guide rail 342 can be moved to adjust the position of the second support seat 334 and the fourth support seat 336 relative to the first support seat 333.

[0190] Step S2: placing the bottom reference plate 120 on the positioned support base 330 .

[0191] Specifically, the bottom positioning large hole 121 of the bottom reference plate 120 is aligned with the tooling cone 331 of the support seat 330, and the bottom reference plate 120 is sleeved onto the tooling cone 331 by means of the guidance of the cone head, so that it can be placed on the top surface of the tooling cone 331. Since the thickness of the bottom reference plates 120 is the same, the top surface of each of the bottom reference plates 120 has the same horizontal coordinate relative to the predetermined reference point.

[0192] Step S3: using the laser positioning instrument 310 to position the bottom reference plate 120 to a position corresponding to a predetermined bottom position.

[0193] In step S3, the bottom reference plate 120 can be positioned by the positioning point of the bottom reference plate 120 according to the laser positioning instrument 310. Referring to the above, this positioning point moves together with the bottom reference plate 120. In this embodiment, the positioning point can be selected at the bottom positioning hole 122. Specifically, a laser reflector can be placed at the bottom positioning hole 122, and the signal reflected by the laser reflector placed at the bottom positioning hole 122 is used to determine whether the positioning point at the bottom positioning hole 122 is located at the preset coordinate value, and the bottom reference plate 120 is horizontally moved around the tooling cone 331 to adjust the position of the positioning point relative to the laser positioning instrument 310. In this way, the positioning of the bottom reference plate 120 in the horizontal direction can be achieved. The above four bottom reference plates 120 can be positioned separately.

[0194] Step S4 : placing the building module 200 on the positioned bottom reference plate 120 and connecting the bottom reference plate 120 to the building module 200 .

[0195] In step S4, the building module 200 is placed under the guidance of the positioning pins 351 and / or the limiting plates 353 of the tooling platform 320. Specifically, the building module 200 can be placed on the bottom reference plate 120 from above the tooling platform 320 by hoisting. In the process of aligning the bottom predetermined position of the building module 200 with the bottom reference plate 120, the building module 200 is moved to the top surface of the bottom reference plate 120 by means of the positioning pins 351 and the limiting plates 353 of the tooling platform 320.

[0196] Considering that the bottom surface of the building module 200 may be uneven, there may be a gap between the building module 200 and the bottom reference plate 120, therefore, in step S4, the bottom gasket 102 may be disposed between the building module 200 and the bottom reference plate 120, so that the bottom surfaces of the plurality of bottom reference plates 120 connected to the building module 200 are coplanar. The bottom gaskets 102 of different thicknesses may be selected, and the positions of the bottom gaskets 102 may be set as required, so that each of the bottom gaskets 102 abuts against the building module 200 and the bottom reference plate 120.

[0197] After the shims are set, the bottom reference plate 120 is connected to the building module 200. Preferably, the bottom reference plate 120 is welded to the building module 200.

[0198] Step S5: placing the top reference plate 110 on the top of the building module 200, and positioning and connecting the top reference plate 110 to the top predetermined position according to the laser positioning instrument 310.

[0199] In step S5, the top surface of each of the top reference plates 110 may be leveled on the same horizontal plane according to the laser positioning instrument 310. It is understood that the top surface of each of the top reference plates 110 has the same horizontal coordinate relative to the predetermined reference point. Specifically, it may be determined whether the height coordinate values ​​of at least three points of the top surface of each of the top reference plates 110 are the same according to the signal reflected by the laser reflector placed on the top surface of the top reference plate 110, so as to adjust the position of the top surface of each of the top reference plates 110. Optionally, three to five points of the top surface of the top reference plate 110 may be selected to determine whether the top surface thereof is horizontal.

[0200] In this embodiment, the top gasket 101 can be arranged between the top reference plate 110 and the building module 200 to level the top surface of the top reference plate 110, so that the top surface of each of the top reference plates 110 can be leveled on the same horizontal plane. Considering that the top surface of the building module 200 may be uneven, it is necessary to support the top reference plate 110 with the help of the top gasket 101 so that its top surface is horizontal. The top gasket 101 of different thicknesses can be selected, and the position of the top gasket 101 can be set as required.

[0201] In step S5, the top reference plate 110 after leveling can be positioned through at least two positioning points of the top reference plate 110 according to the laser positioning instrument 310. In this embodiment, the positioning points can be selected at the positioning cone positioning hole 112 and the top positioning hole 113. Specifically, taking the top positioning hole 113 as an example, a laser reflector can be placed at the top positioning hole 113, and the signal reflected by the laser reflector placed at the top positioning hole 113 is used to determine whether the positioning point at the top positioning hole 113 is located at the preset coordinate value, and the top reference plate 110 is horizontally moved around the tooling cone 331 to adjust the position of the positioning point relative to the laser positioning instrument 310. In this way, the positioning of the top reference plate 110 in the horizontal direction can be achieved. The above four top reference plates 110 can be positioned separately.

[0202] The positioned top reference plate 110 is connected to the building module 200. Preferably, the top reference plate 110 is welded to the building module 200.

[0203] Furthermore, the connection method also includes step S6 after step S5: stacking two building modules 200 connected with the top reference plate 110 and the bottom reference plate 120 up and down, and connecting the bottom reference plate 120 of the upper building module to the top reference plate 110 of the lower building module.

[0204] Specifically, the superstructure module (refer to Figure 4 The first building module 210 in the figure moves to the lower building module (refer to Figure 4 In the process of aligning the bottom reference plate 120 of the upper building module with the top reference plate 110 of the lower building module, the bottom positioning large hole 121 of the bottom reference plate 120 of the upper building module can be set to the positioning cone 111 of the top reference plate 110 of the lower building module by means of the guidance of the cone head 114 of the positioning cone 111 to locate the position of the upper building module. Then, the top connection hole 118 of the corresponding top reference plate 110 and the bottom connection hole 123 of the bottom reference plate 120 are connected by means of fasteners 170 such as bolts.

[0205] Furthermore, the connection method further comprises step S7 after step S5: horizontally arranging two building modules 200 connected with the top reference plate 110 and the bottom reference plate 120 , and connecting the top reference plates 110 of adjacent building modules via a horizontal connector 180 .

[0206] Specifically, two building modules 200 (see Figure 4After the third building module 230 and the fourth building module 240 are arranged side by side and aligned, the horizontal connector positioning holes of the horizontal connector 180 are respectively sleeved onto the positioning cones 111 of the top reference plates 110 of the two building modules 200 to locate the position of the horizontal connector 180.

[0207] In an embodiment where a plurality of building modules 200 are stacked up and down and arranged horizontally, for example, in a case where two lower building modules and two upper building modules are included, step S7 may be performed first, and then step S6 may be performed. Thus, the upper building module can be placed above the lower building module only after the horizontal connector 180 is placed on the top reference plate 110 of the lower building module. And the positioning cone 111 of the top reference plate 110 of the lower building module may pass through the horizontal connector positioning hole of the horizontal connector 180 and the bottom reference plate 120 of the upper building module. Finally, the top connection hole 118 of the top reference plate 110, the horizontal connector positioning hole of the horizontal connector 180, and the bottom connection hole 123 of the bottom reference plate 120 are connected correspondingly by means of fasteners 170 such as bolts to form a stacked building module device.
