Description

Technical Field

[0001] The utility model relates to the technical field of beam-slab-column structures, in particular to an assembled beam-slab-column joint structure. Background Technique

[0002] The beam-column joint refers to the intersection point of the beam and column of the frame structure. The beam and column components of the frame structure are easy to be standardized and shaped, which is convenient for adopting the assembled integral structure to shorten the construction period; when using the cast-in-place concrete frame, the integrity and stiffness of the structure are good, and good seismic resistance effects can also be achieved if the design is properly handled.

[0003] For example, Chinese Patent Publication No. CN220266846U discloses an assembled beam-slab-column joint structure, which includes multiple hollow bottom columns and multiple hollow connecting column caps. The multiple hollow bottom columns are evenly distributed longitudinally and horizontally and fixedly connected to the ground. Multiple steel bars are vertically arranged inside the hollow bottom columns, and concrete is poured inside. A circle of limiting edges is arranged in the middle of the inner walls around the hollow connecting column caps. The hollow connecting column caps are sleeved on the tops of the hollow bottom columns. The utility model effectively solves the defects existing in the prior art by prefabricating the hollow bottom columns, the hollow connecting column caps, the floor slabs and the structural beams, and pouring concrete after hoisting and assembling.

[0004] However, in the above solution, when splicing the beam-slab, it is not convenient to limit and fix the beam-slab, so that the beam-slab is prone to offset and slide when placed on the two limiting edges, and the convenience is not high. Content of the Utility Model

[0005] The utility model provides an assembled beam-slab-column joint structure to solve the problems raised in the above background technique.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] An assembled beam-slab-column joint structure includes a hollow bottom column and a connecting column. Two rectangular clamping grooves are opened on the top of the hollow bottom column and on the side walls at both ends of the connecting column. A supporting plate is arranged between the hollow bottom column and the connecting column. Rectangular connecting rods are fixedly connected to both side walls of the supporting plate. One rectangular connecting rod on one side of the supporting plate is clamped in the two rectangular clamping grooves on one side between the hollow bottom column and the connecting column. U-shaped clamping plates are fixedly connected to one ends of the two rectangular connecting rods. Both ends of one of the U-shaped clamping plates extend into the hollow bottom column and the connecting column. A structural beam is fixedly connected to the top of the supporting plate. Clamping grooves are opened on both side walls of the supporting plate. Multiple limiting rods are fixedly connected to the top of the supporting plate. The multiple limiting rods are respectively located on both sides of the structural beam. Two of the limiting rods are provided with a beam-slab body at the top. Two limiting holes are opened at both ends of the beam-slab body. The two limiting holes at one end of the beam-slab body are respectively sleeved on the outer side walls of the two limiting rods.

[0008] As a further improvement of this technical solution: a reinforcing rib is fixedly connected to the bottom of the beam-slab body, and the bottom of the reinforcing rib abuts against one of the card slots.

[0009] As a further improvement of this technical solution: the bottom diameter of each of the limiting rods is larger than the top diameter.

[0010] As a further improvement of this technical solution: the hollow bottom column and the connecting column have exactly the same shape and structure, both are square tubular structures, and are both precast by pouring concrete and steel bars.

[0011] As a further improvement of this technical solution: the bottom side wall of the connecting column abuts against the top side wall of the hollow bottom column.

[0012] Compared with the prior art, the beneficial effects of the present utility model are: through the mutual cooperation of components such as the support plate, the limiting rod, the U-shaped clamping plate, and the rectangular connecting rod, the device can automatically limit and fix the beam-slab during the splicing of the beam-slab, thereby preventing the phenomenon of offset and sliding of the beam-slab after splicing. The operation is simple, convenient and fast.

[0025] Please refer to Figures 1-5, in the embodiment of the present utility model, an assembled beam-slab-column joint structure includes a hollow bottom column 1 and a connecting column 4. Two rectangular card slots 12 are provided on the top of the hollow bottom column 1 and on the side walls at both ends of the connecting column 4. A support plate 2 is provided between the hollow bottom column 1 and the connecting column 4. Rectangular connecting rods 11 are fixedly connected to both side walls of the support plate 2. The rectangular connecting rods 11 on one side of the support plate 2 are stuck in the two rectangular card slots 12 on one side between the hollow bottom column 1 and the connecting column 4. U-shaped clamping plates 10 are fixedly connected to one ends of the two rectangular connecting rods 11. Both ends of one of the U-shaped clamping plates 10 extend into the hollow bottom column 1 and the connecting column 4. A structural beam 3 is fixedly connected to the top of the support plate 2. Card slots 9 are provided on both side walls of the support plate 2. A plurality of limiting rods 7 are fixedly connected to the top of the support plate 2. The plurality of limiting rods 7 are respectively located on both sides of the structural beam 3. A beam-slab body 6 is provided on the top of two of the limiting rods 7. Two limiting holes 8 are provided at both ends of the beam-slab body 6. The two limiting holes 8 at one end of the beam-slab body 6 are respectively sleeved on the outer side walls of the two limiting rods 7.

[0026] Please refer to Figure 1 , Figure 5 , a reinforcing rib 5 is fixedly connected to the bottom of the beam-slab body 6. The bottom of the reinforcing rib 5 abuts against one of the card slots 9, which can facilitate the strengthening of the hardness of the beam-slab body 6, thereby improving the load-bearing performance of the beam-slab body 6.

[0027] Please refer to Figures 1-3 , Figure 5 , the bottom diameter of each limiting rod 7 is larger than the top diameter, which can increase the contact area between the bottom of each limiting rod 7 and the support plate 2, thereby improving the stability of each limiting rod 7 and making its bottom not easy to break.

[0028] Please refer to Figures 1-2 , Figure 4 , 5 , the hollow bottom column 1 and the connecting column 4 have exactly the same shape and structure, both are square tubular structures, and are both precast by pouring concrete and steel bars, which can reduce the weight of the hollow bottom column 1 and the connecting column 4, thereby facilitating the hoisting of the hollow bottom column 1 and the connecting column 4. After hoisting, concrete can be poured into the hollow bottom column 1 and the connecting column 4.

[0029] Please refer to Figures 1-2 , Figures 4-5 , the bottom side wall of the connecting column 4 abuts against the top side wall of the hollow bottom column 1, which can prevent a large gap from being generated between them after the hollow bottom column 1 and the connecting column 4 are installed, thereby contributing to the later pouring of concrete into the hollow bottom column 1 and the connecting column 4.

[0030] The working principle of the utility model is as follows: Fix a plurality of hollow bottom columns 1 on the ground, then simultaneously clamp the two U-shaped clamping plates 10 on the opposite surfaces of the two support plates 2 inside the hollow bottom column 1, so that the two rectangular connecting rods 11 on the side walls of the two U-shaped clamping plates 10 are clamped in the two rectangular clamping grooves 12 at the top of the hollow bottom column 1. Then, the two rectangular clamping grooves 12 at the bottom of the connecting column 4 can be clamped on the top of the rectangular connecting rods 11, and the two U-shaped clamping plates 10 enter the connecting column 4 at the top, thereby splicing the hollow bottom column 1 and the connecting column 4. The two ends of the two U-shaped clamping plates 10 are clamped inside the hollow bottom column 1 and the connecting column 4, which is convenient for limiting and fixing the connecting column 4. The side walls of the two U-shaped clamping plates 10 are attached to form a rectangular frame, which is convenient for pouring concrete into the hollow bottom column 1 and the connecting column 4 later. Then, the two limiting holes 8 on the side wall of the beam and slab body 6 can be sleeved on the tops of the two limiting rods 7, which is convenient for quickly splicing and limiting the beam and slab body 6, making the beam and slab body 6 unable to move, thereby preventing the beam and slab body 6 from shifting and sliding after installation. The space between the beam and slab bodies 6 on both sides of the hollow bottom column 1 can be sealed by the cooperation of the expansion glue and the sealing plate.

[0031] The above is only the preferred embodiment of the present utility model, and it does not impose any form of limitation on the present utility model. Any ordinary technician in the industry can smoothly implement the present utility model according to the instructions in the attached drawings and the above description. However, any equivalent changes such as slight modifications, refinements, and evolutions made by those skilled in the art within the scope of the technical solution of the present utility model using the technical content disclosed above are all equivalent embodiments of the present utility model. At the same time, any equivalent changes, modifications, and evolutions made to the above embodiments based on the essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
