Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically, to a large opening protection structure acting on a suspended beam. Background Art

[0002] In the field of building construction, large openings provided on structural slabs play a crucial role. These large openings are usually designed for equipment installation, pipeline laying, or as temporary passages in subsequent construction stages, which greatly improve construction efficiency and flexibility. However, as the project progresses, the large opening areas often become weak links during the construction process. Due to the large area of the large openings, the surrounding structures are prone to instability when bearing construction loads. For example, when hoisting building materials or equipment, it is easy to have collisions between the building materials and the edge of the opening, resulting in damage to the edge of the opening and even more serious structural safety problems. This situation will not only affect the construction progress but also pose a direct threat to the safety of on-site operators. Content of the Utility Model

[0003] To make up for the above deficiencies, the utility model provides a large opening protection structure acting on a suspended beam to solve the above problems.

[0004] The utility model is implemented as follows:

[0005] A large opening protection structure acting on a suspended beam includes two parallel suspended beam bodies. Main fixing parts are arranged at both ends of the suspended beam bodies. On the relative side of the two suspended beam bodies, there is a side mounting plate. The side mounting plate includes a right-angle connecting side plate arranged on one side of the suspended beam body. A lower fixing plate is arranged at the top of the right-angle connecting side plate. An opening protection plate is arranged at the top of the lower fixing plate. The opening protection plate includes two upper fixing plates. The two upper fixing plates are symmetrically arranged at the large opening and surround the inner side and the top edge of the large opening.

[0006] In an embodiment of the utility model, two groups of first installation grooves are horizontally opened on the relative side of the two suspended beam bodies.

Detailed implementation manners

[0020] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Therefore, the detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Such as Figures 1-4As shown in the figure, the utility model provides a large-hole protection structure acting on a suspended beam, which includes two parallel suspended beam bodies 10. Main fixing parts 11 are arranged at both ends of the suspended beam body 10, and the main fixing parts 11 are fixed between two structural beams 50, so that the two suspended beam bodies 10 are located on both sides of the bottom of the large hole. At the same time, a side mounting plate 20 is arranged on the opposite side of the two suspended beam bodies 10. The side mounting plate 20 includes a right-angle connecting side plate 21 arranged on one side of the suspended beam body 10. A lower fixing plate 22 is arranged at the top of the right-angle connecting side plate 21, and a hole protection plate 30 is arranged at the top of the lower fixing plate 22. The hole protection plate 30 includes two upper fixing plates 31, and the two upper fixing plates 31 are symmetrically arranged at the large hole and surround the inner side and the top edge of the large hole, forming a protection structure for the large hole. It can effectively disperse and absorb the impact force generated during the hoisting process, protect the edge of the hole from damage, and ensure safety and stability during the construction process, providing a strong guarantee for the smooth progress of building construction.

[0023] In this embodiment, two groups of first installation grooves 1001 are horizontally opened on the opposite sides of the two suspended beam bodies 10. One side of the right-angle connecting side plate 21 is fixedly arranged at the first installation grooves 1001 through bolts, and the position of the right-angle connecting side plate 21 on the suspended beam body 10 can be adjusted according to the actual situation. An installation hole 2101 is opened at the center of the other side of the right-angle connecting side plate 21.

[0024] Furthermore, a number of mutually connected positioning holes 2201 are linearly equally divided at the top of the lower fixing plate 22. A first bolt 23 is arranged between the positioning holes 2201 and the installation hole 2101. During specific installation, ensure that the installation hole 2101 on the right-angle connecting plate is coaxial with one of the positioning holes 2201, and then sequentially penetrate the first bolt 23 through the positioning hole 2201 and the installation hole 2101 from the top of the lower fixing plate 22, and fix it with a nut, that is, the fixation of the side mounting plate 20 is completed.

[0025] In this embodiment, the same positioning holes 2201 as those of the lower fixing plate 22 are opened at the top of the upper fixing plate 31. Second bolts 32 are inserted into the positioning holes 2201 near both ends of the upper fixing plate 31. The second bolts 32 penetrate through the coaxial positioning holes 2201 on the lower fixing plate 22 and are fixed with nuts. A resisting spring 33 is arranged between the upper fixing plate 31 and the lower fixing plate 22 on the second bolts 32. When a protection relationship is formed between the upper fixing plate 31 and the large hole, the upper fixing plate 31 is separated from the lower fixing plate 22 through the resisting spring 33, which is convenient for subsequent assembly and avoids manually fixing the upper fixing plate 31 at the large hole. Right-angle extension parts extending outward are arranged at both ends of one side of the upper fixing plate 31. A flange 3101 is arranged on the outer side of the top of the upper fixing plate 31. When the second bolts 32 are tightened, the bottom of the flange 3101 abuts against the top edge of the large hole.

[0026] As a preferred embodiment, the edge of the flange 3101 is chamfered to make the connection between the flange 3101 and the structural plate 40 relatively smooth, thereby facilitating the transportation of building materials.

[0027] In this embodiment, a docking groove 3102 is provided at one end of the top of the right-angle extension portion, and a threaded hole 3103 is provided in the docking groove 3102. When the two upper fixing plates 31 are fixed on the lower fixing plate 22, the right-angle extension portions are in contact with each other, and the two opposite docking grooves 3102 form a completed groove, in which a docking plate 34 is provided. The docking plate 34 is fixed in the docking groove 3102 by two third bolts 35, so that the two upper fixing plates 31 form a complete rectangular structure, which can protect the entire inner side and top edge of the large opening.

[0028] In the embodiment, the two lower hanging beam bodies 10 are fixed between two parallel structural beams 50 through the main fixing members 11 respectively, so that they are located at the two parallel sides of the bottom of the large opening, and a plurality of side mounting plates 20 are fixed at the first mounting grooves 1001 by bolts, and the two upper fixing plates 31 are arranged on the side mounting plates 20 by second bolts 32. Specifically, the second bolts 32 pass through the upper fixing plates 31 and the lower fixing plates 22 in sequence, and a resistance spring 33 is also arranged between the upper fixing plates 31 and the lower fixing plates 22. When not tightened, the resistance spring 33 exerts an upward elastic force on the upper fixing plates 31, so that the flange 3101 on the upper fixing plates 31 is away from the edge of the large opening, so as to facilitate the adjustment of the azimuth angle during installation. After tightening, the flange 3101 is tightly in resistance with the top edge of the large opening, and at the same time, the right-angle extensions of the two upper fixing plates 31 are fixed together by the docking plate 34 to form a complete rectangular protective structure, which protects the entire inner side and the top edge of the large opening.

[0029] The above structure solves the problem in the prior art that when hoisting building materials or equipment, the edge of the hole will collide with it, causing damage to the edge of the hole and causing structural safety problems, which not only affects the construction progress but also poses a threat to the safety of on-site workers.

[0030] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as a limitation on the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
