Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of modular building, and particularly relates to a connecting node of a prefabricated module and a corridor prefabricated plate and a building structure. BACKGROUND

[0002] Modular building is a new building structure system, which takes each room as a module unit, and each module unit is prefabricated in a factory, transported to a site and assembled into a building whole through a reliable connecting mode. The building structure can reduce on-site construction work, has a fast construction speed and greatly improves the industrialization level of the building.

[0003] In a building with multiple layers of modules, a corridor prefabricated plate needs to be installed on each layer of structure. In modular building, the prefabricated module and the corridor prefabricated plate need to be assembled at a construction site, and the side plate of the prefabricated module is connected with the corridor prefabricated plate, so that the prefabricated module and the corridor prefabricated plate are connected as a whole and jointly constitute the entire building structure. In the related art, the prefabricated module and the corridor prefabricated plate are generally connected through bolts. When the prefabricated module and the corridor prefabricated plate are connected through the bolts, the bolts need to be screwed. However, in the actual construction process, the building structure is complex, and the installation of the bolts is inconvenient, so that the connection of the prefabricated module and the corridor prefabricated plate is not convenient. SUMMARY

[0004] In order to improve the convenience of the connection of the prefabricated module and the corridor prefabricated plate, the present application provides a connecting node of a prefabricated module and a corridor prefabricated plate and a building structure.

[0005] The present application provides a connecting node of a prefabricated module and a corridor prefabricated plate and a building structure, which adopts the following technical scheme:

[0006] In a first aspect, the present application provides a connecting node of a prefabricated module and a corridor prefabricated plate, which adopts the following technical scheme: a connecting node of a prefabricated module and a corridor prefabricated plate, comprising a connecting plate for connecting the prefabricated module and the corridor prefabricated plate and a plug-in rod for plugging the corridor prefabricated plate, wherein the plug-in rod is arranged on the connecting plate.

[0007] The connecting plate comprises a bearing part for bearing the corridor prefabricated plate and a connecting part for fixedly connecting with the prefabricated module, wherein the connecting part is arranged on the bearing part, and the plug-in rod is fixedly arranged on the bearing part.

[0008] By adopting the technical scheme, when the connecting node is used to assemble the prefabricated module and the corridor prefabricated plate, the corridor prefabricated plate is installed on the receiving part, and the inserting rod of the connecting node is inserted into the corridor prefabricated plate, so that the movement of the corridor prefabricated plate in the horizontal direction on the receiving part is limited, and the connecting node and the corridor prefabricated plate are firmly connected. The connecting part of the connecting plate is fixedly connected with the prefabricated module, so that the connecting node firmly connects the corridor prefabricated plate and the connecting plate. Compared with the traditional bolt connection, in the technical scheme, only the connecting node and the corridor prefabricated plate are inserted, and the corridor prefabricated plate and the prefabricated module can be firmly connected, and the installation is more convenient.

[0009] Optionally, the end surface of the inserting rod is provided with a through hole.

[0010] By adopting the technical scheme, the weight of the inserting rod is reduced after the through hole is formed, and the manufacturing material is saved. When the connecting node is used to connect the corridor prefabricated plate and the prefabricated module, the inserting rod is fixedly installed on the receiving part, and the receiving part receives the corridor prefabricated plate, and the receiving part bears a large load. The through hole on the inserting rod reduces the load received by the receiving part, so that the receiving part is not easy to be broken due to excessive load, and the service life of the connecting node is prolonged.

[0011] Optionally, a plurality of connecting holes are arranged on the outer circumferential surface of the inserting rod, and the connecting holes are communicated with the through hole.

[0012] By adopting the technical scheme, when the concrete is bonded with the inserting rod and the insertion part of the corridor prefabricated plate, the concrete outside the inserting rod can be bonded with the concrete in the through hole of the inserting rod, so as to limit the relative movement of the inserting rod and the corridor prefabricated plate, thereby improving the firmness of the connection between the connecting node and the corridor prefabricated plate.

[0013] Optionally, the receiving part comprises a first receiving segment for receiving the corridor prefabricated plate and a mounting segment for mounting the inserting rod, the inserting rod is located on the upper surface of the mounting segment, and the first receiving segment is located between the mounting segment and the connecting part.

[0014] By adopting the technical scheme, when the connecting node is used to connect the prefabricated module and the corridor prefabricated plate, the inserting rod located on the mounting segment is inserted into the corridor prefabricated plate, so that the displacement of the corridor prefabricated plate in the horizontal direction is limited. The part between the insertion part of the corridor prefabricated plate and the prefabricated module is located on the first receiving segment, the first receiving segment supports the corridor prefabricated plate, improves the strength of the connection between the connecting node and the corridor prefabricated plate, and makes the connection not easy to be damaged.

[0015] Optionally, the receiving part comprises a second receiving segment, and the second receiving segment is located on the side of the mounting segment away from the first receiving segment.

[0016] By adopting the technical scheme, when the corridor prefabricated slab is connected with the prefabricated module through the connecting joint, the first receiving section and the second receiving section jointly support the corridor prefabricated slab, the design can increase the load capacity of the receiving part as a whole, the receiving part is not prone to bending deformation or fracture due to excessive load, and thus the connecting strength of the connecting joint is improved.

[0017] Optionally, the plug-in rod is a square tube.

[0018] By adopting the technical scheme, compared with a circular tube, the square tube has greater bending resistance and torsional resistance and is not prone to deformation. When the connecting joint connects the corridor prefabricated slab and the prefabricated module, the corridor prefabricated slab and the prefabricated module apply pressure to the connecting joint in opposite directions, so that the connecting joint needs to bear greater load, and the structure of the square tube replacing the circular tube can prolong the service life of the connecting joint.

[0019] In a second aspect, the building structure provided in the application adopts the following technical scheme:

[0020] A building structure comprises:

[0021] The connecting joint of the prefabricated module and the corridor prefabricated slab;

[0022] An upper prefabricated module;

[0023] A lower prefabricated module, the connecting part being fixedly connected between the upper prefabricated module and the lower prefabricated module;

[0024] A corridor prefabricated slab, the connecting plate being parallel to the corridor prefabricated slab, one end of the corridor prefabricated slab for connecting with the prefabricated module being an installation part, the installation part abutting against the upper surface of the receiving part, the corridor prefabricated slab being provided with an installation cavity for plugging in the plug-in rod, and the installation cavity being filled with concrete for bonding the connecting joint and the corridor prefabricated slab.

[0025] By adopting the technical scheme, the plug-in rod is plugged into the installation cavity, the installation cavity is filled with concrete, the concrete fills the space between the outer wall of the plug-in rod and the inner wall of the installation cavity and the through hole of the plug-in rod, the through hole enables the concrete to contact the inner wall and the outer wall of the plug-in rod, so that the bonding area of the concrete and the plug-in rod is increased, and the structural strength of the building structure is improved. In addition, the concrete in the plug-in rod and the concrete outside the plug-in tube can penetrate each other through the connecting hole, and the concrete solidifies to bond the plug-in rod and the corridor prefabricated slab together, so that the plug-in rod and the corridor prefabricated slab are fixedly connected. Compared with the traditional bolt connection, the plug-in rod and the corridor prefabricated slab are connected more firmly by adopting the plug-in and concrete bonding mode of the connecting joint.

[0026] Optionally, the installation cavity has an upper opening and a lower opening, the upper opening is located on the upper surface of the installation part, and the lower opening is located on the lower surface of the installation part.

[0027] By adopting the technical scheme, when the assembly connection joint is connected with the corridor prefabricated slab, the insertion rod can enter the installation cavity from the lower opening, the upper surface of the connection plate is attached to the lower surface of the corridor prefabricated slab, and the concrete is poured into the installation cavity from the upper opening, so that the insertion rod located in the installation cavity is firmly bonded to the inner wall of the installation cavity by the concrete, and the connection joint is firmly connected with the corridor prefabricated slab.

[0028] Optionally, the cross-sectional area of the upper opening is greater than the cross-sectional area of the lower opening.

[0029] By adopting the technical scheme, after the connection joint assembles the corridor prefabricated slab, the upper layer prefabricated module and the lower layer prefabricated module, the concrete can be poured into the installation cavity and the through hole of the insertion rod from the upper opening of the installation cavity, and the cross-sectional area of the upper opening is greater than the cross-sectional area of the lower opening, so that the concrete is conveniently poured. The inner wall of the installation cavity can play a guiding role, so that the concrete can enter the installation cavity along the inner wall of the installation cavity, and the uniformity of the concrete distribution is improved.

[0030] The shape of the concrete in the installation cavity after solidification is basically the same as the shape of the installation cavity, and the concrete will have a downward movement trend under the action of gravity. Since the lower opening is smaller than the upper opening, the concrete will be blocked by the lower opening of the installation cavity when it moves downward after solidification, limiting the downward movement of the concrete in the installation cavity from the lower opening, so that the insertion rod located in the installation cavity is firmly bonded to the inner wall of the installation cavity by the concrete, thereby increasing the strength of the entire structure.

[0031] Optionally, the installation cavity is provided with a reinforcing steel bar.

[0032] By adopting the technical scheme, after the insertion rod is installed in the installation cavity, the reinforcing steel bar is embedded in the concrete when the concrete is poured into the installation cavity, so that the concrete firmly bonds the reinforcing steel bar and the connection joint, thereby increasing the strength and reliability of the connection joint.

[0033] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] 1. Compared with the traditional bolt connection, by connecting the prefabricated module and the corridor prefabricated slab through the connection joint, only the insertion rod of the connection joint is inserted into the corridor prefabricated slab, and the concrete is poured into the installation cavity, which not only realizes the convenience of the connection between the prefabricated module and the corridor prefabricated slab, but also improves the structural strength of the building structure.

[0035] 2. The through hole of the plug-in rod is arranged to make the concrete contact with the inner wall and the outer wall of the plug-in rod, so as to increase the bonding area of the concrete and the plug-in rod, thereby improving the firmness of the connection between the plug-in rod and the inner wall of the installation cavity;

[0036] 3. When the concrete is used to bond the plug-in rod and the corridor prefabricated slab, the concrete outside the plug-in rod can be bonded with the concrete in the through hole of the plug-in rod through the connecting hole, so as to limit the relative movement of the plug-in rod and the corridor prefabricated slab, thereby improving the firmness of the connection between the connection joint and the corridor prefabricated slab.

[0049] The following will be described in detail in combination with the accompanying Figures 1-4 The present application will be further described in detail.

[0050] The embodiment of the present application discloses a building structure.

The two precast modules are distributed along a vertical direction, the upper precast module is an upper precast module 3 and the lower precast module is a lower precast module 4. The connecting node 2 is partially clamped between the upper precast module 3 and the lower precast module 4 to achieve a preliminary fixation, and then the connecting node 2 is connected to the corridor precast slab 1 to achieve a fixed connection between the corridor precast slab 1 and the two precast modules.

[0053] Reference Figure 1 The corridor precast slab 1 is generally provided in the form of a rectangular plate. The edge of the corridor precast slab 1 is provided with a mounting portion 11 for mounting the connecting node 2. The mounting portion 11 is provided with a mounting cavity 111 extending along the vertical direction. The mounting cavity 111 can be filled with concrete to improve the connection stability between the mounting portion 11 and the connecting node 2. The cross section of the mounting cavity 111 is generally rectangular, and the mounting cavity 111 has an upper opening 1111 and a lower opening 1112, the upper opening 1111 is located on the upper surface of the mounting portion 11, and the lower opening 1112 is located on the lower surface of the mounting portion 11. The cross-sectional area of the upper opening 1111 is larger than that of the lower opening 1112.

[0054] Reference Figure 2 The connecting node 2 comprises a connecting plate 21 and a plug-in rod 22 fixedly arranged on the upper surface of the connecting plate 21, and the plug-in rod 22 is perpendicular to the connecting plate 21. The connecting plate 21 is used to connect the precast modules and the corridor precast slab 1, and the plug-in rod 22 is used to plug and fix the corridor precast slab 1.

[0055] Reference Figure 2 The plug-in rod 22 is arranged along the vertical direction, and the plug-in rod 22 is provided with a through hole 221 centered on the axis. The through hole 221 can be filled with concrete to improve the firmness of the connecting node 2. In this embodiment, the plug-in rod 22 is a square hole, one of the end faces of the square hole is fixedly installed above the connecting plate 21. During assembly, the plug-in rod 22 is inserted into the mounting cavity 111 from the lower opening 1112 of the mounting cavity 111, and then the mounting cavity 111 is filled with concrete. The concrete enters the through hole 221 in the mounting cavity 111 at the same time, and the connection between the plug-in rod 22 and the corridor precast slab 1 is achieved after the concrete solidifies.

[0056] In another embodiment, in order to further improve the firmness of the connection between the plug-in rod 22 and the corridor precast slab 1, a plurality of connecting holes are provided through the side wall of the plug-in rod 22, and the connecting holes are in communication with the through hole 221 in the plug-in rod 22. After the concrete is poured, the concrete outside the plug-in rod 22 and the concrete in the through hole 221 are solidified together through the connecting holes, and the concrete and the plug-in rod 22 form a clamping connection, thereby limiting the relative movement between the plug-in rod 22 and the corridor precast slab 1.

[0057] Referring to Figure 1 and Figure 2 In the present embodiment, the connecting plate 21 is in the shape of a rectangular plate and is horizontally placed. The connecting plate 21 is divided into a receiving portion 211 and a connecting portion 212 along the length direction thereof, the receiving portion 211 supports the lower surface of the corridor precast slab 1, and the connecting portion 212 is clamped between the upper precast module 3 and the lower precast module 4.

[0058] Referring to Figure 1 and Figure 2 The receiving portion 211 includes, in sequence, a first receiving section 2111, a mounting section 2112, and a second receiving section 2113 in the direction away from the connecting portion 212. The insertion rod 22 is arranged at the mounting section 2112, and the mounting section 2112 closes the lower opening 1112 of the mounting cavity 111. The first receiving section 2111 is located between the insertion rod 22 and the connecting portion 212, and the second receiving section 2113 is located on the side of the insertion rod 22 away from the connecting portion 212. The first receiving section 2111 and the second receiving section 2113 are used to support the precast corridor slab. Specifically, the second receiving section 2113 can support the part of the corridor precast slab 1 between the inner wall of the mounting cavity 111 and the upper precast module 3, so that the mounting cavity 111 has sufficient wall thickness, thereby making the mounting cavity 111 not easy to be damaged. The arrangement of the first receiving section 2111 and the second receiving section 2113 enables the precast corridor slab 1 to be sufficiently supported, the stress of the receiving portion 211 is more uniform, and thus the connection strength of the connecting node 2 and the precast corridor slab 1 is higher.

[0059] It is worth mentioning that, in order to improve the load capacity of the receiving portion 211, a beam support 5 supporting the lower surface of the receiving portion 211 is further arranged on the lower precast module 4. Referring to Figure 1 One end of the beam support 5 is fixedly connected to the side outer wall of the lower precast module 4 close to the precast corridor slab 1. The beam support 5 can provide support force to the precast corridor slab, thereby improving the structural stability of the building structure.

The mounting portion 11 of the precast corridor slab 1 is placed on the upper surface of the receiving portion 211, and the insertion rod 22 is inserted into the mounting cavity 111 from the lower opening 1112.

[0062] (2) Pour the concrete into the installation cavity 111 from the opening 1111 of the installation cavity 111, and the concrete fills the installation cavity 111 and the through hole 221 of the insertion rod 22. After the concrete solidifies, the connecting joint 2 and the corridor prefabricated slab 1 are connected together, thereby realizing the convenience of the connection between the prefabricated module and the corridor prefabricated slab 1, and improving the firmness of the connection between the prefabricated module and the corridor prefabricated slab 1.
