Description

Technical Field

[0001] This utility model relates to the field of building beam and column technology, and more specifically, to a modular building beam and column node high-efficiency connection clamp. Background Technology

[0002] With the rapid development of the construction industry, modular buildings are increasingly widely used in modern construction due to their advantages such as short construction cycle, energy saving and environmental protection, and controllable quality. In modular buildings, the connection quality of beam-column joints directly affects the stability and safety of the building structure and is a key link to ensure the overall performance of modular buildings. Efficient and reliable beam-column joint connection methods can accelerate the construction progress and reduce construction costs, which is of great significance to promoting the development of modular buildings.

[0003] In the market, beam-column joints are generally fixed using traditional welding methods. Although traditional welding connections are relatively simple to operate, the welding process requires professional technicians, the construction speed is slow, and it is greatly affected by environmental factors such as weather. It is also prone to welding deformation and cracks, which affect the accuracy of the building.

[0004] Some beam-column joints also utilize numerous bolt connections. While bolted connections facilitate installation and disassembly, the large number of bolts makes the installation process cumbersome and positioning difficult, leading to low construction efficiency. This is especially true when dozens of bolts are used to fix each joint, making the entire process even more complex and inconvenient for construction operations. There is an urgent need to develop a new type of beam-column joint connection clamp to address the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency connection clamp for modular building beam-column joints to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

Multiple first through holes are provided on the left and right side plates of the main clamp body. A secondary clamp body is clamped and fitted in the inner clamping groove. A bottom pressure-resistant plate is fixedly installed on the inner wall of the secondary clamp body. Multiple V-shaped pressure-resistant plates arranged linearly and at equal intervals are fixedly installed between the bottom pressure-resistant plate and the top wall of the secondary clamp body. Multiple second through holes are provided on the V-shaped pressure-resistant plates and the left and right side plates of the secondary clamp body. A long limiting rod is inserted and fitted in the first and second through holes.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model achieves rapid positioning and installation of the clamp by setting the inner clamping groove of the main clamping body to engage with the secondary clamping body, and the guiding structure of the top inclined surface and the upper clamping block, which reduces the complex positioning and operation process in traditional welding or bolt connection; the long limiting rod, together with the forward stud, reverse stud and nut fixing method, makes the installation simpler and faster than a large number of bolt connections, and greatly improves the construction efficiency of beam and column joints.

[0020] 2.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Please see Figures 1-4 This utility model provides a technical solution: a modular building beam-column joint high-efficiency connection clamp, including a main clamp body 1. The main clamp body 1 is provided with an inner clamping groove 13 that is connected to the outside at the top. Multiple first through holes 12 are provided on the left and right side plates of the main clamp body 1. A secondary clamp body 2 is clamped and fitted in the inner clamping groove 13, so that the secondary clamp body 2 can be quickly positioned in the main clamp body 1. A bottom anti-compression plate 24 is fixedly installed on the inner wall of the secondary clamp body 2. Multiple V-shaped anti-compression plates 22 arranged linearly and equally spaced are fixedly installed between the bottom anti-compression plate 24 and the top wall of the secondary clamp body 2. The cross-section of the V-shaped anti-compression plate 22 is V-shaped. Two adjacent V-shaped anti-compression plates 22 and the bottom anti-compression plate 24 form a triangular structure, which can utilize the stability of the triangle to achieve a stable support effect, ensuring that the overall structure is more solid and stable, and enhancing the support strength and compressive strength of the connection clamp for the beam-column joint.

[0032] In this embodiment, multiple second through holes 23 are provided on both the left and right sides of the V-shaped anti-compression plate 22 and the sub-clip body 2. A long limiting rod 3 is inserted into the first through hole 12 and the second through hole 23. A limiting protrusion 30 is fixedly installed at one end of the long limiting rod 3, and the other end of the long limiting rod 3 is fixed by a nut 33. Compared with the cumbersome operation of traditional large number of bolts, the installation process is simplified.

[0033] Specifically, the main clamping body 1 is fixedly installed on the lower beam and column, and the upper beam and column are installed on the top surface of the secondary clamping body 2. Specifically, the bottom plate of the main clamping body 1 is provided with multiple first bolt holes 10, and the top plate of the secondary clamping body 2 is provided with multiple second bolt holes 21. The first bolt holes 10 and the second bolt holes 21 are used for bolt insertion and fixed installation on the corresponding beam, so as to achieve convenient fixed installation on the corresponding beam by fastening bolts.

[0034] like Figures 1-3 As shown, both the main card body 1 and the secondary card body 2 have U-shaped cross sections. The bottom surface of the secondary card body 2 abuts against the bottom wall of the inner card groove 13. Multiple bottom pressure-resistant columns 25 arranged linearly and at equal intervals are fixedly installed on the bottom surface of the bottom pressure-resistant plate 24. The bottom pressure-resistant columns 25 abut against the bottom wall of the inner card groove 13, which plays a stable supporting role and ensures that the overall structure is more solid and stable.

[0035] like Figure 4 As shown, a forward stud 31 is fixedly installed at the end of the long limiting rod 3 away from the limiting protrusion 30, and a reverse stud 32 is fixedly installed at the end of the forward stud 31. Nuts 33 are threaded onto both the forward stud 31 and the reverse stud 32. The external spiral directions on the surfaces of the forward stud 31 and the reverse stud 32 are opposite, so that the two nuts 33 can be used to perform the fixing operation and prevent loosening.

[0036] It is worth noting that the top left and right sides of the inner card slot 13 are provided with top inclined surfaces 11. The top inclined surfaces 11 are inclined at 15 to 30 degrees towards the outside of the main card body 1. The top of the left and right sides of the sub-card body 2 are fixedly installed with upper clamping blocks 20. The upper clamping blocks 20 abut against the top inclined surfaces 11, so that the sub-card body 2 can play a guiding role in the process of inserting the main card body 1, making the assembly more convenient and facilitating efficient connection operations.

[0037] When using the modular building beam-column node high-efficiency connection clamp of this utility model, the main clamp body 1 is first fixed to the beam-column below by bolts through the first bolt hole 10 on the bottom plate.

[0038] Subsequently, using the guiding effect of the top inclined surfaces 11 on the left and right sides of the top of the inner card slot 13 and the upper abutting block 20 on the top of the side plate of the secondary card body 2, the secondary card body 2 is inserted into the inner card slot 13 of the main card body 1 until the bottom surface of the secondary card body 2 abuts against the bottom wall of the inner card slot 13, and at the same time the bottom anti-pressure column 25 also abuts against the bottom wall of the inner card slot 13, thus completing the initial positioning;

[0039] Next, the long limiting rod 3 is passed sequentially through the first through hole 12 on the side plate of the main clamping body 1, the V-shaped anti-compression plate 22, and the second through hole 23 on the side plate of the auxiliary clamping body 2, so that the limiting protrusion 30 is locked on the outside of the main clamping body 1. After the forward-facing stud 31 and the reverse-facing stud 32 at the other end of the long limiting rod 3 are passed out, nuts 33 are screwed on respectively. By rotating the nuts 33, the main clamping body 1 and the auxiliary clamping body 2 are tightly fixed using the reverse thread design, completing the beam-column joint connection. Finally, the upper beam-column and the auxiliary clamping body 2 are further reinforced with bolts through the second bolt hole 21 on the top plate of the auxiliary clamping body 2 to ensure a firm and reliable connection.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
