Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a connection structure for modular construction of rural houses and its modular construction. Background Technology

[0002] Modular prefabricated construction technology, as a modern building method, has brought a new direction to rural housing construction with its unique advantages. It can not only effectively solve many problems existing in traditional rural housing construction methods, such as long construction cycles, serious resource waste, and inconsistent quality, but also improve the overall quality of rural housing.

[0003] Currently, modular buildings used for rural housing are broken down into multiple prefabricated modules. After precise production in the factory, these modules are transported to the site for direct hoisting and assembly. While this method is fast and efficient, fully meeting the requirements of high integration, rapid construction, and quick commissioning, on-site assembly typically involves sleeve grouting. This leads to problems such as exposed rebar and a large workload during traditional frame joint pouring. Furthermore, sleeve grouting is complex, costly, and difficult to guarantee in terms of grout density, affecting connection strength. In addition, due to the lack of professional construction teams in rural areas, existing construction workers are unfamiliar with prefabricated construction technology and lack relevant skills training, making it difficult to ensure the construction quality of connection joints.

[0035] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1:

[0037] like Figure 1 and Figure 2 As shown, this embodiment provides a connection structure for modular farmhouse construction. The connection structure includes a non-edge connection component 1 and an edge connection component 2. The non-edge connection component 1 is disposed at the adjacent joint of concrete modules 31, used to connect horizontally adjacent non-edge concrete modules 31. The edge connection component 2 is disposed on the concrete modules 31 located at the edges, used to connect horizontally adjacent edge concrete modules 31. When the non-edge connection component 1 or the edge connection component 2 is stacked symmetrically with respect to the horizontal plane, it connects vertically adjacent concrete modules 31. Because the non-edge connection component 1 and the edge connection component 2 are used for horizontal connections between concrete modules 31, and when the non-edge connection component 1 or the edge connection component 2 is stacked symmetrically with respect to the horizontal plane, it connects vertically adjacent concrete modules 31, reducing the complexity of connections between modules. During construction, only grouting is required at the non-edge connection component 1 and the edge connection component 2, reducing grouting difficulty and the cost of connection materials, and avoiding the problems of complex and non-dense grouting processes in existing technologies.

[0038] It should be noted that the non-edge connection component 1 or the edge connection component 2 being stacked symmetrically relative to the horizontal plane means that the two non-edge connection components 1 or the two edge connection components 2 are mirror-symmetrically arranged on the horizontal plane and positioned one above the other.

[0039] In order to effectively strengthen the connection strength between concrete modules 31 at the non-edge joints of adjacent joints, thereby improving the stability and safety of the entire modular farmhouse building. Figure 1As shown, the non-edge connection component 1 includes a first connecting plate 11 and four connecting columns 12 perpendicularly arranged to the first connecting plate 11. The first connecting plate 11 has four first through holes, and the connecting columns 12 are hollow components that communicate with the first through holes to form a casting channel. This allows multiple concrete modules 31 to form an integrated load-bearing system in the horizontal direction, thereby improving the overall integrity and seismic performance of the building.

[0040] Non-edge connection components 1 are disposed at adjacent joints of the top-layer concrete modules 31 to connect horizontally adjacent non-edge concrete modules 31. Two non-edge connection components 1 are symmetrically arranged and stacked vertically along the first connecting plate 11, and are disposed at adjacent joints of the middle-layer concrete modules 31 to connect vertically adjacent non-edge concrete modules 31.

[0041] It should be noted that a non-edge connection component 1 can simultaneously connect four horizontally adjacent concrete modules 31 located on the top layer, and two stacked non-edge connection components 1 can simultaneously connect eight vertically adjacent and horizontally adjacent concrete modules 31, which simplifies the assembly process and improves construction speed and efficiency.

[0042] In order to effectively strengthen the connection strength between concrete modules 31 at the edges of adjacent joints, thereby improving the stability and safety of the entire modular farmhouse building, such as Figure 2 As shown, the edge connection component 2 includes a second connecting plate 21 and two connecting columns 12 perpendicularly arranged to the second connecting plate 21. The second connecting plate 21 has two second through holes, and the connecting columns 12 are hollow components that communicate with the second through holes to form a casting channel. The edge connection component 2 can achieve a more stable structural connection without increasing additional space, which helps to optimize the spatial layout and utilization efficiency of the building.

[0043] Edge connection components 2 are disposed on the top layer and located at the edge of the concrete module 31, and are used to connect horizontally adjacent edge concrete modules 31. Two edge connection components 2 are symmetrically arranged and stacked on top of each other along the second connection plate 21, and are disposed on the middle layer and located at the edge of the concrete module 31, and are used to connect vertically adjacent and horizontally adjacent edge concrete modules 31.

[0044] It should be noted that one edge connection component 2 can simultaneously connect two horizontally adjacent concrete modules 31 located on the top layer, and two stacked edge connection components 2 can simultaneously connect four vertically adjacent and horizontally adjacent concrete modules 31, which simplifies the assembly process and improves construction speed and efficiency.

[0045] Preferably, such as Figure 1 and Figure 2As shown, the connecting column 12 is a columnar structure formed by sequentially connecting the side ends of four third connecting plates 121, creating a cavity structure. To facilitate the subsequent injection of grout into the concrete module 31, connecting the concrete module 31 with the non-edge connecting component 1 or with the edge connecting component 2, several third through holes 1211 are provided on each of the four third connecting plates 121. The third through holes 1211 can increase the contact area between the grout and the concrete module 31, significantly improving the pull-out performance and thus enhancing the overall integrity.

[0046] In a preferred embodiment of the present invention, each third connecting plate 121 has two third through holes 1211.

[0047] In a preferred embodiment of the present invention, the first connecting plate 11, the second connecting plate 21 and the third connecting plate 121 are all steel plates.

[0048] Furthermore, to facilitate insertion with the concrete module 31, reduce resistance, and improve assembly efficiency, such as... Figure 1 and Figure 2 As shown, the end of the connecting post 12 that is away from the first connecting plate 11 or the second connecting plate 21 is tightened inward.

[0049] Example 2:

[0050] This embodiment is the same as embodiment 1 in all other aspects, except that, as shown in the example below. Figure 3 and Figure 4 As shown, when the non-edge connection component 1 is stacked symmetrically with respect to the horizontal plane, it forms a single-piece structure, consisting of a first connecting plate 11 and eight connecting columns 12 perpendicularly arranged to it, connecting vertically adjacent non-edge concrete modules 31. Similarly, when the edge connection component 2 is stacked symmetrically with respect to the horizontal plane, it forms a single-piece structure, consisting of a second connecting plate 21 and four connecting columns 12 perpendicularly arranged to it, connecting vertically adjacent edge concrete modules 31. This design effectively controls installation errors and improves the reliability of the connection nodes by filling the gaps with poured concrete.

[0051] Example 3:

[0052] like Figure 5 As shown, this embodiment provides a modular building for farmhouses. The modular building includes the connecting structure for modular farmhouses in Embodiment 1 and at least two layers of concrete modules 3, each concrete module 3 comprising concrete modules 31 arranged longitudinally and transversely.

[0053] like Figure 5As shown, each layer of concrete module 3 includes six concrete modules 31 arranged in a longitudinal and transverse pattern. These six concrete modules 31 are arranged in two rows and three columns. The two left columns of concrete modules 31 form a group of "four adjacent concrete modules 31", and the two right columns of concrete modules 31 form a group of "four adjacent concrete modules 31". It can be understood that the middle column of concrete modules 31 forms a group of "four adjacent concrete modules 31" with the columns to its left and right. Of course, this embodiment is only one example. A single layer of concrete module 3 can have only four concrete modules 31 arranged in two rows and two columns, or it can have nine concrete modules 31 arranged in three rows and three columns, twelve concrete modules 31 arranged in three rows and four columns, sixteen concrete modules 31 arranged in four rows and four columns, and so on. There can also be more than two layers of concrete module 3. Preferably, this utility model is particularly beneficial for farmhouses composed of two or three layers of concrete module 3.

[0054] Each concrete module 31 is a hexahedral precast component, consisting of a top plate 311, a bottom plate 312, four side plates 313, four crossbeams 314, and four columns 315. The bottom of the top plate 311 is connected to the top of the four crossbeams 314. The upper and lower ends of the columns 315 of the concrete modules 31 to be connected have a first hole 3151 and a second hole 3152, respectively, for insertion into the non-edge connection component 1 or the edge connection component 2. "Adjacent concrete modules 31" refers to every two adjacent concrete modules 31 in the same column and every two adjacent concrete modules 31 in the same row.

[0055] In this concrete module 31, the top plate 311 is located on top of the crossbeam 314. Unlike the traditional configuration where the crossbeam 314 is located on top of the top plate 311, this arrangement makes the connection between modules easier.

[0056] Furthermore, such as Figure 6 As shown, a rectangular through groove 316 extends from the connecting edge of the top plate 311 and the crossbeam 314 on the adjacent side of each of the two adjacent concrete modules 31 at the top layer. The depth of the rectangular through groove 316 does not exceed the thickness of the top plate 311 and the width does not exceed the width of the crossbeam 314 of the concrete module 31. The first hole 3151 is opened at the bottom of the rectangular through groove 316.

[0057] It should be noted that the rectangular through-slot 316 is opened along the extension direction of the connecting edge of the top plate 311 and the crossbeam 314 on the adjacent sides of two adjacent concrete modules 31, and the rectangular through-slot 316 can form a pouring space. Since the rectangular through-slot 316 is opened along the length of the top plate 311 at the connecting edge of the top plate 311 and the crossbeam 314, which is slightly different from the traditional module, the rectangular through-slot 316 facilitates the subsequent pouring of concrete, improves the integrity of the individual module, and enhances the stability of the farmhouse.

[0058] In a preferred embodiment of the present invention, the first hole 3151 and the second hole 3152 are rectangular holes with a length of 120mm, a width of 120mm, and a depth of 350mm.

[0059] like Figure 5 As shown, the concrete module 3 also includes a building top plate 32, which is located on top of the top concrete module 3.

[0060] In order to ensure that the grout can fill the pouring channel evenly, such as Figure 8 As shown, a grouting hole 31521 and a grout outlet hole 31522 are provided between the second hole 3152 and the column 315. The grouting hole 31521 is located below the grout outlet hole 31522. Grout enters through the grouting hole 31521 and flows out through the grout outlet hole 31522. Grouting is performed from the grouting hole 31521 until grout flows out evenly from the grout outlet hole 31522. Then, the grouting hole 31521 and the grout outlet hole 31522 are sealed. Grout for the concrete module 31 located at the top layer is injected through the top opening of its first hole 3151.

[0061] At the non-edge joints of the four concrete modules 31 arranged in a longitudinal and transverse manner, non-edge connecting components 1 are used to connect with the corresponding first hole 3151 and / or second hole 3152. At the edges of the concrete modules 31, edge connecting components 2 are used to connect with the corresponding first hole 3151 and / or second hole 3152 above and below.

[0062] Specifically, such as Figures 6 to 8 As shown, at the non-edge joints of the four top-layer concrete modules 31 arranged longitudinally and transversely, non-edge connecting components 1 are inserted into the corresponding first holes 3151. At the non-edge joints of the four intermediate-layer concrete modules 31 arranged longitudinally and transversely, two stacked non-edge connecting components 1 are inserted into the corresponding second holes 3152 and first holes 3151. The connecting posts 12 of the non-edge connecting components 1 are inserted into the corresponding second holes 3152 and first holes 3151, respectively, enabling precise positioning and efficient installation of the intermediate-layer concrete modules 3.

[0063] Specifically, such as Figures 6 to 8 As shown, at the edges of adjacent joints of the four top-layer concrete modules 31 arranged in a longitudinal and transverse pattern, edge connecting components 2 are inserted into the corresponding first holes 3151. At the edges of adjacent joints of the four intermediate-layer concrete modules 31 arranged in a longitudinal and transverse pattern, two stacked edge connecting components 2 are inserted into the corresponding second holes 3152 and first holes 3151, enabling precise positioning and efficient installation of the intermediate-layer concrete modules 3.

[0064] Specifically, such as Figure 6 and Figure 7 As shown, the first connecting plate 11 and the second connecting plate 21 are both placed in the rectangular through groove 316. The connecting column 12 is inserted into the first hole 3151 of the adjacent concrete module 31 at the top layer, which enables precise positioning and efficient installation of the concrete module 3 at the top layer. Since the bottom of the first connecting plate 11 and the second connecting plate 21 are connected to the top of the rectangular through groove 316, grouting can be directly injected into the pouring channels at the non-edge connecting component 1 and the edge connecting component 2 while the rectangular through groove 316 is being poured and sealed with concrete, eliminating the need for secondary grouting and improving the assembly efficiency of the farmhouse.
