Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a novel prefabricated composite board connection structure. Background Art

[0002] The composite slab is a kind of prefabricated slab, which is made of truss steel bars and cast-in-place reinforced concrete base plate. It has good integrity and high rigidity, which can improve the seismic performance of the structure. At the same time, the prefabricated composite slab saves formwork, reduces construction costs, and improves the economic benefits of construction.

[0003] In the current construction technology of composite slabs, multiple composite slabs are easily affected by factors such as quality and size deviation, positioning deviation, crack generation and transmission of bending moment when spliced ​​together, resulting in certain gaps after multiple composite slabs are spliced ​​together. The gaps will affect the overall stress of the floor slab, thereby reducing the integrity of the floor slab. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a novel prefabricated composite slab connection structure to solve the problem that certain gaps are generated when multiple composite slabs are spliced, thereby reducing the integrity of the floor slab.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model is as follows: a new type of prefabricated composite board connection structure, including a composite board body, and also includes:

[0006] A plurality of connecting tubes are arranged on one side of the composite plate body, and a plurality of embedding grooves for embedding the connecting tubes of adjacent composite plate bodies are arranged on the other side of the composite plate body; a glue injection cavity is arranged between the inner wall of the embedding groove of the composite plate body and the outer wall of the connecting tube, and a glue injection port connected with the glue injection cavity is arranged on the other side of the composite plate body.

[0007] The technical principle of the utility model is as follows: when splicing two adjacent composite board bodies, the composite board bodies are first hoisted to the designated installation position by a lifting device, and then the construction personnel align the connecting pipe with the embedding groove. When the connecting pipe is aligned with the embedding groove, the two adjacent composite board bodies are installed and spliced ​​together by translation; when the side walls of the two adjacent composite board bodies are fitted together, epoxy resin or polyurethane structural glue is poured into the glue cavity formed by the connection through the glue pouring port, and the glue is waited for to be formed, thus forming a new type of assembled composite board with uniform force and firm connection.

[0008] Furthermore, the plurality of embedding grooves correspond one-to-one to the plurality of connecting pipes on the adjacent composite plate bodies.

[0009] Through the above arrangement, the connecting pipe can be connected to the embedding grooves on the adjacent superimposed plate bodies in a one-to-one correspondence, so that the connection between the two adjacent superimposed plate bodies is more stable.

[0010] Furthermore, the connecting pipe is tubular, and a fixing rod is coaxially fixedly arranged inside the connecting pipe;

[0011] A spring and a limit block are radially arranged in the connecting tube, one end of the spring is fixedly connected to the outer wall of the fixing rod, and the other end of the spring is fixedly connected to the limit block. The connecting tube is radially provided with a sliding hole for radial sliding of the limit block, and a groove for embedding the limit block is provided on the inner wall of the embedding groove of the superimposed plate body; when the connecting tube of the superimposed plate body is completely embedded in the embedding groove of the adjacent superimposed plate body, the limit block is embedded in the groove.

[0012] Through the above-mentioned arrangement, the embedding groove of the superimposed plate body is abutted against the limit block. When the superimposed plate bodies are horizontally close to each other, the superimposed plate bodies press the limit block and the spring, and the spring contracts, so that the limit block moves back along the sliding hole to the embedding groove, so that the connecting pipe continues to be embedded in the embedding groove. When the side walls of the two adjacent superimposed plate bodies are fitted together, the spring naturally stretches, so that the limit block is positioned in the embedding groove, thereby achieving stable limiting of the connecting pipe and the embedding grooves on the adjacent superimposed plate bodies, and achieving stable limiting between the two adjacent superimposed plate bodies.

[0013] Furthermore, the side of the limit block away from the spring is a wedge surface, and the thickness of the limit block at one end close to the spring is greater than the thickness of the limit block at one end away from the spring.

[0014] Through the above arrangement, the embedding groove of the composite plate body abuts against the wedge surface of the limit block, thereby accurately converting the abutting pressure into a compression force on the spring, making it easier for the limit block to slide along the sliding hole.

[0015] Furthermore, the longitudinal section of the embedding groove is rectangular, and a plurality of positioning blocks of uniform thickness are fixedly mounted on the outer wall of the connecting pipe, and the plurality of positioning blocks can abut against at least two inner walls of the embedding groove at the same time.

[0016] Through the above arrangement, the positioning block can limit the cooperation between the connecting tube and the embedding groove, so that a glue pouring cavity with uniform thickness is formed between the side wall of the embedding groove and the connecting tube, so that during the glue pouring process, the glue can be evenly filled between the connecting tube and the embedding groove.

[0017] Furthermore, the number of the positioning blocks is two, and the positioning blocks abut against two adjacent sides of the embedding groove away from the glue injection port.

[0018] Through the above arrangement, two positioning blocks can position both sides of the embedding groove and the connecting pipe. The two positioning blocks occupy less space and can more easily accommodate more glue for fixing.

[0019] Furthermore, the number of the glue injection ports is two, one of which is located opposite to the middle of the embedding groove, and the other is located opposite to the bottom of the embedding groove.

[0020] By setting up two glue pouring ports, the pouring direction and position are more uniform during glue pouring, so that the distribution of glue in the glue pouring cavity is more uniform and dense.

[0021] Furthermore, the plurality of connecting pipes are all located at the middle of the side wall of the composite plate body, and the plurality of connecting pipes are evenly arranged along the length direction of the side wall of the composite plate body.

[0022] Through the above arrangement, the cooperation between the connecting pipe and the embedding groove between two adjacent laminated plate bodies is made more uniform and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0029] This embodiment is basically Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the embodiment of the utility model proposes a novel prefabricated composite plate connection structure, including a composite plate body 10 and three connecting pipes 20, the connecting pipe 20 is tubular, and a fixing rod 201 is coaxially welded inside the connecting pipe 20; Figure 1 As shown, three connecting tubes 20 are evenly welded along the length direction of the lower side of the composite plate body 10. The connecting tubes 20 are vertically arranged. Three embedding grooves 101 for embedding the connecting tubes 20 of adjacent composite plate bodies 10 are vertically arranged on the upper side of the composite plate body 10. The connecting tubes 20 and the embedding grooves 101 are both located in the middle of the side walls of the composite plate body 10. The three embedding grooves 101 correspond one by one to the three connecting tubes 20 on the adjacent composite plate bodies 10.

[0030] like Figure 3 and4 As shown, a glue pouring cavity 205 is provided between the inner wall of the embedding groove 101 of the composite plate body 10 and the outer wall of the connecting tube 20, and two glue pouring ports 102 connected to the glue pouring cavity 205 are provided on the other side of the composite plate body 10, one of the glue pouring ports 102 is located opposite to the middle of the embedding groove 101, and the other glue pouring port 102 is opposite to the bottom of the embedding groove 101.

[0031] like Figure 2-4 As shown, two springs 202 and two limit blocks 204 are radially arranged in the connecting tube 20, and the two limit blocks 204 are symmetrically arranged along the horizontal axis of the fixing rod 201, and the two springs 202 are also symmetrically arranged along the horizontal axis of the fixing rod 201; one end of the spring 202 is welded to the outer wall of the fixing rod 201, and the other end of the spring 202 is welded to the limit block 204, and the connecting tube 20 is radially provided with a sliding hole 203 for radial sliding of the limit block 204, and a groove 103 for the limit block 204 to be embedded on the inner wall of the embedding groove 101 of the composite plate body 10; when the connecting tube 20 of the composite plate body 10 is completely embedded in the embedding groove 101 of the adjacent composite plate body 10, the limit block 204 is embedded in the groove 103; the side of the limit block 204 away from the spring 202 is a wedge surface, and the thickness of the limit block 204 close to the spring 202 is greater than the thickness of the limit block 204 away from the spring 202.

[0032] like Figure 2-4 As shown, the longitudinal cross-sectional profile of the embedding groove 101 is rectangular, and two positioning blocks 206 of uniform thickness are fixedly installed on the outer wall of the connecting tube 20. The positioning blocks 206 abut against the adjacent two sides of the embedding groove 101 away from the glue filling port 102. One of the positioning blocks 206 is welded to the left end of the outer wall of the connecting tube 20, and the other positioning block 206 is welded to the right end of the outer wall of the connecting tube 20.

[0033] When installing a new type of prefabricated composite board connection structure in this embodiment, the composite board body 10 is hoisted to the designated installation position by a lifting device, and then the construction personnel align the connecting pipe 20 with the embedding groove 101. After the connecting pipe 20 is aligned with the embedding groove 101, the two adjacent composite board bodies 10 are installed and spliced ​​together. Figure 3As shown, the embedding groove 101 of the composite plate body 10 abuts against the wedge surface of the limit block 204. When the composite plate bodies 10 are horizontally close to each other, the composite plate body 10 presses the limit block 204 and the spring 202 through the wedge surface, and the spring 202 contracts, so that the limit block 204 moves back along the sliding hole 203 to the embedding groove 101, so that the connecting pipe 20 continues to be embedded in the embedding groove 101. When the side walls of two adjacent composite plate bodies 10 are attached, the spring 202 naturally stretches, so that the limit block 204 is stuck in the position of the groove 103. The stable limiting of the connecting tube 20 and the embedding groove 101 on the adjacent superimposed plate body 10 is achieved, and the limiting stability between the two adjacent superimposed plate bodies 10 is achieved; at the same time, the two positioning blocks 206 can limit the cooperation between the connecting tube 20 and the embedding groove 101, so that a glue pouring cavity 205 with uniform thickness is formed between the side wall of the embedding groove 101 and the connecting tube 20, so that during the glue pouring process, the glue can be evenly filled between the connecting tube 20 and the embedding groove 101, so that the cooperation between the two adjacent superimposed plate bodies 10 is more stable.

[0034] When performing glue filling, Figure 4 As shown, a high-pressure glue pouring machine 40 is used to pour epoxy resin or polyurethane structural glue into the glue pouring cavity 205 formed by the connection through the glue pouring port 102, and the glue is waited for to be formed, thus forming a new type of assembled composite panel with uniform force and stable connection.
