Description

Technical Field

[0001] This utility model relates to the field of precast beam and column technology, specifically a beam and column joint connection structure for prefabricated buildings. Background Technology

[0002] Prefabricated beams and columns are the most important supporting components in prefabricated buildings. They refer to the prefabricated columns and beams in the factory, which are then transported to the construction site for assembly and connection to form the load-bearing structure of the building.

[0003] In the existing technology, the connection of prefabricated beams and columns involves setting embedded parts at the ends of the prefabricated beams and columns, then connecting them to the embedded parts on site and fixing them with bolts. Finally, concrete is poured to completely encapsulate and fix the connectors and embedded parts, forming an integral connection with good integrity and seismic performance.

[0004] However, during concrete pouring, the grouting inside the joint grooves where the connectors are inserted into the upper beams and columns is not dense enough, resulting in voids and affecting the structural stability. Based on this, a prefabricated building beam-column joint connection structure is provided. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated building beam-column joint connection structure in order to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated building beam-column joint connection structure, comprising a prefabricated column consisting of a column body, rectangular embedded parts, and a connecting groove, and a connecting component. The rectangular embedded parts are symmetrically embedded and fixed at the upper and lower ends of the column body, and the connecting groove is formed inside the rectangular embedded parts. The connecting component is used to realize the connection and assembly operations of the upper and lower prefabricated columns and the prefabricated beam and the prefabricated column.

[0007] The connecting assembly includes an I-shaped connector, a U-shaped fixing plate, and a side connecting plate;

[0008] The two U-shaped fixing plates are symmetrically fixed to the outside of the I-shaped connecting piece, and the side connecting plates are distributed between the two U-shaped fixing plates and welded to the I-shaped connecting piece and the U-shaped fixing plates;

[0009] The upper and lower ends of the I-shaped connector are used to insert into the connecting grooves on the upper and lower precast columns. The U-shaped fixing plate is attached to the rectangular embedded part and fixed by bolts to realize the vertical docking assembly of the upper and lower precast columns.

[0010] The upper and lower outer sides of the column body are formed with a U-shaped groove, and the rear end face of the U-shaped groove is provided with a grouting hole that penetrates into the docking groove.

[0011] When the two precast columns are assembled by the connecting components and concrete is poured, the grouting holes are used to ensure that the concrete can fully fill the docking groove, and the U-shaped grooves are used to ensure that the concrete can completely cover the upper and lower ends of the column body and the connecting components.

[0012] As a further improvement of this utility model: multiple grouting holes are evenly arranged vertically, and the bottommost grouting hole is flush with the bottom of the inner wall of the docking groove, and the opening of the I-shaped docking part is aligned with the location of the grouting hole.

[0013] As a further improvement of this utility model: the front and rear ends of the central horizontal plate of the I-shaped docking component are also fixed with reinforcing convex plates, which are distributed at an angle.

[0014] As a further embodiment of this utility model: multiple reinforcing protrusions are evenly arranged vertically, and two vertically adjacent reinforcing protrusions have opposite inclination directions.

[0015] As a further embodiment of this utility model: the precast beam includes a main body of the beam and an I-shaped embedded part. The I-shaped embedded part is embedded and fixed on both sides of the main body of the beam. The main body of the beam is connected to the side connecting plate through the I-shaped embedded part and fixed with bolts to achieve connection and assembly with the precast column.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By setting up precast columns with grouting holes, concrete can be injected from the topmost grouting hole of the upper precast column, which can completely fill the joint groove on the upper and lower precast columns. This effectively avoids the situation where the concrete is not fully filled in the joint groove of the precast column, thus effectively ensuring the stability of the structure. In addition, by strengthening the structural setting of the convex plate, the connection force between the cast concrete and the I-shaped joint is further improved. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-3 In this embodiment of the utility model, a prefabricated building beam-column node connection structure includes a prefabricated column 1 composed of a column body 101, a rectangular embedded part 102, and a connecting groove 103, as well as a connecting component 2. The rectangular embedded part 102 is symmetrically embedded and fixed at the upper and lower ends of the column body 101, and the connecting groove 103 is formed on the inner side of the rectangular embedded part 102. The connecting component 2 is used to realize the connection and assembly operation of the upper and lower prefabricated columns 1 and the prefabricated beam 3 with the prefabricated column 1.

[0024] The connecting component 2 includes an I-shaped connector 201, a U-shaped fixing plate 202, and a side connecting plate 203;

[0025] Two U-shaped fixing plates 202 are symmetrically fixed to the outside of the I-shaped connecting piece 201, and the side connecting plates 203 are distributed in the middle of the two U-shaped fixing plates 202 and are welded and fixed to the I-shaped connecting piece 201 and the U-shaped fixing plates 202.

[0026] The upper and lower ends of the I-shaped connector 201 are used to insert into the connecting grooves 103 on the upper and lower precast columns 1. The U-shaped fixing plate 202 is attached to the rectangular embedded part 102 and fixed by bolts to realize the vertical docking assembly of the upper and lower precast columns 1.

[0027] The upper and lower outer sides of the column body 101 are formed with a U-shaped groove 104, and the rear end face of the U-shaped groove 104 is provided with a grouting hole 105 that penetrates into the docking groove 103.

[0028] When the two precast columns 1 are assembled by the connecting component 2 and concrete is poured, the grouting hole 105 is used to ensure that the concrete can fully fill the docking groove 103, and the back groove 104 is used to ensure that the concrete can completely cover the upper and lower ends of the column body 101 and the connecting component 2.

[0029] Multiple grouting holes 105 are evenly arranged vertically, and the bottommost grouting hole 105 is flush with the bottom of the inner wall of the docking groove 103. The opening of the I-shaped docking piece 201 is aligned with the location of the grouting hole 105.

[0030] The precast beam 3 includes a main beam 301 and an I-shaped embedded part 302. The I-shaped embedded part 302 is embedded and fixed on both sides of the main beam 301. The main beam 301 is connected to the side connecting plate 203 through the I-shaped embedded part 302 and fixed with bolts to achieve connection and assembly with the precast column 1.

[0031] In this embodiment, the connection structure between the connecting component 2 and the precast column 1 and the precast beam 3 is the same as the connection structure of existing prefabricated building beams and columns: the upper and lower ends of the I-shaped connecting piece 201 are inserted into the connecting groove 103 on the upper and lower precast columns 1, the U-shaped fixing plate 202 is fixed to the rectangular embedded part 102 by bolts, and the precast beam 3 is connected to the side connecting plate 203 by the I-shaped embedded part 302 and fixed with bolts to realize the assembly and fixation of the precast column 1. The operation method is the same as the assembly of existing prefabricated building beams and columns, so it will not be described in detail here.

[0032] After the precast column 1, precast beam 3 and connecting component 2 are assembled and fixed, a casting mold is erected at the assembly position, and then concrete is poured at this position. During this process, concrete grouting can be performed through the uppermost grouting hole 105 of the upper precast column 1. At this time, the concrete will flow down along the docking groove 103 of the upper precast column 1 to the docking groove 103 of the lower precast column 1, and flow outward through the grouting hole 105 on the lower precast column 1 to the inside of the U-shaped groove 104 and the casting mold.

[0033] Afterwards, the concrete is slowly filled upwards, eventually completely filling the connection position between the connecting component 2 and the precast beam 3, the inside of the butt groove 103 of the upper precast column 1, and the U-shaped groove 104 of the upper precast column 1. After the concrete solidifies, the overall installation operation is completed.

[0034] By coordinating the above components, the situation of incomplete concrete filling in the connecting groove 103 of the upper precast column 1 can be effectively avoided, thus ensuring the structural stability.

[0035] Please refer to this carefully. Figures 1-3 The front and rear ends of the central horizontal plate of the I-shaped connector 201 are also fixed with reinforcing convex plates 204, which are distributed at an angle.

[0036] Multiple reinforcing protrusions 204 are evenly arranged vertically, and two adjacent reinforcing protrusions 204 are inclined in opposite directions.

[0037] In this embodiment, multiple reinforcing convex plates 204 can effectively increase the connection force between the later poured concrete and the I-shaped connector 201, thereby further improving the stability of the structure. By setting the inclined structure of the reinforcing convex plates 204, they will not block the downward flow of concrete, ensuring the complete filling effect of the concrete.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
