Description

Technical Field

[0001] This utility model relates to the field of cantilever steel beam anchoring technology, and more specifically, to an adjustable building scaffolding cantilever steel beam installation structure. Background Technology

[0002] In construction engineering, cantilevered steel beams are an important supporting structure for high-rise building construction. One end is anchored to the main building structure, while the other end extends outwards for scaffolding erection. The installation structure must ensure safety and stability, providing a working platform for construction workers and facilitating construction operations.

[0003] Patent CN220644630U discloses a pre-embedded tapered threaded sleeve anchoring structure for cantilever steel beams. The tapered threaded sleeve is pre-embedded in the concrete structure. The main body of the cantilever steel beam to be anchored is placed inside the anchoring assembly. The upper and lower locking nuts are rotated to loosen or tighten the pressure plate. The installation position of the pressure plate is quickly adjusted according to the specifications of the cantilever steel beam, ensuring that the inner surface of the pressure plate is tightly against the top of the cantilever steel beam, thus anchoring the top of the cantilever steel beam. The first and second side locking nuts are rotated to loosen or tighten the second screw, adjusting its lateral position so that one end of the second screw is tightly against the side of the cantilever steel beam, thus anchoring both sides of the cantilever steel beam. However, in the above-mentioned anchoring structure, the anchoring of the cantilever steel beam body relies on the end abutment of the two screws, which cannot stably and effectively anchor the cantilever steel beam body; at the same time, since the two tapered threaded sleeves are pre-embedded structures and the spacing between the two first screws is fixed, it can only be used to anchor cantilever steel beams within a certain width range, thus limiting its application scope.

[0036] 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.

[0037] like Figures 1-3 As shown, this embodiment provides an adjustable cantilever steel beam installation structure for building scaffolding, including a first side clamp 1 and a second side clamp 2 arranged opposite to each other, and two parallel U-shaped positioning components. Each U-shaped positioning component includes two parallel positioning rods. One positioning rod of the U-shaped positioning component passes through the first side clamp 1, and the other positioning rod passes through the second side clamp 2. The distance between the first side clamp 1 and the second side clamp 2 is adjustable. The first side clamp 1 and the second side clamp 2 are adjusted so that they abut against both sides of the web of the cantilever steel beam body 4. At this point, the top of the U-shaped positioning component, after passing through the first side clamp 1 and the second side clamp 2, is tightened with a nut, thus achieving the positioning and installation of the cantilever steel beam body. In this embodiment, the U-shaped positioning component is a U-shaped bolt 3 pre-embedded in the concrete floor slab 5, and its positioning rod is a screw 31. The U-shaped bolt is sleeved on the reinforcing mesh of the concrete floor slab to enhance its stability.

[0038] In this embodiment, the first side clamp 1 and the second side clamp 2, which are arranged opposite to each other, abut against the two sides of the web plate of the cantilever steel beam body 4.

[0039] Specifically, such as Figures 1-7 As shown, the first side clamp 1 includes a horizontally arranged first top plate 11 and a first auxiliary plate 12, and also includes a first frame 13 for abutting against one side of the web of the cantilever steel beam body 4. The first frame 13 is fixed to the lower end face of the first top plate 11, and the first auxiliary plate 12 is fixed to the middle of the first frame 13. The widths of the first top plate 11 and the first auxiliary plate 12 are the same, while the width of the first frame 13 is smaller than the width of the first top plate 11.

[0040] Furthermore, the first top plate 11 has two parallel upper strip-shaped holes 111, and the first auxiliary plate 12 has two parallel lower strip-shaped holes 121. The upper strip-shaped holes 111 and the lower strip-shaped holes 121 overlap vertically, and one of the screws 31 of the U-bolt 3 passes through the upper and lower strip-shaped holes 111 and 121. Due to the strip-shaped design of the upper and lower strip-shaped holes 111 and 121, the first top plate 11 and the first auxiliary plate 12 can move along the screws 31, thereby adjusting the position of the first side clamp 1 so that it can abut against one side of the web of the cantilever steel beam body 4.

[0041] The first frame 13 is a U-shaped frame with its opening facing left. One end of it is fixed to the lower end face of the first top plate 11 via a first upper connecting plate 14. The first upper connecting plate 14 is a vertically arranged plate, and it is fixed to the position between two first upper strip holes 111 on the lower end face of the first top plate 11. Therefore, the first frame 13 does not obstruct the movement of the first side clamp 1 along the screw. The first frame 13 is also fixed to two first lower connecting plates 15, which are fixed to the lower end face of the first auxiliary plate 12. One end of the first auxiliary plate 12 is fixed to the inner side of the first frame 13.

[0042] Specifically, such as Figures 1-5 , Figure 8 and Figure 9 As shown, the second side clamp 2 includes a horizontally arranged second top plate 21 and a second auxiliary plate 22, with the second top plate 21 abutting against the upper end face of the first top plate 11; it also includes a second frame 23 for abutting against the other side of the web of the cantilever steel beam body 4; the second frame 23 is fixed to the lower end face of the second top plate 21, and the second auxiliary plate 22 is fixed to the middle of the second frame 23. The widths of the second top plate 21 and the second auxiliary plate 22 are the same, while the width of the second frame 23 is smaller than the width of the second top plate 21.

[0043] Furthermore, the second top plate 21 has two sets of parallel upper strip-shaped holes 211, and the second auxiliary plate 22 has two parallel lower strip-shaped holes 221. The upper and lower strip-shaped holes 211 and 221 overlap vertically, and the thread 31 of the U-bolt 3 passes through the upper and lower strip-shaped holes 211 and 221. Due to the strip-shaped design of the upper and lower strip-shaped holes 211 and 221, the second top plate 21 and the second auxiliary plate 22 can move along the thread 31, thereby adjusting the position of the second side clamp 2 so that it can abut against one side of the web of the cantilever steel beam body 4.

[0044] The second frame is a U-shaped frame with its opening facing right (23). One end of the frame is fixed to the lower end face of the second top plate 21 via a second upper connecting plate 24. The second upper connecting plate 24 is a vertically arranged plate, and it is fixed to the position between two second upper strip holes 211 on the lower end face of the second top plate 21. Therefore, the second frame 23 will not obstruct the movement of the second side clamp 2 along the screw. The second frame 23 is also fixed with two second lower connecting plates 25, which are fixed to the lower end face of the second auxiliary plate 22. One end of the second auxiliary plate 22 is fixed to the inside of the second frame 23.

[0045] When fixing the cantilever steel beam body 4, firstly, the first side clamp 1 is inserted through the thread on the same side of the two U-bolts, and then the second side clamp 2 is inserted through the thread on the other side of the two U-bolts. At this time, the first top plate 11 in the first side clamp 1 abuts against the top surface of the cantilever steel beam body 4, and the second top plate 21 in the second side clamp 2 abuts against the upper end surface of the first top plate 11. Due to the design of each strip hole, the first side clamp 1 and the second side clamp 2 are then moved towards each other, and the first frame 13 and the second frame 23 abut against the two sides of the web of the cantilever steel beam body 4 respectively. Then, nuts are screwed into each U-bolt, and the nuts abut against the upper end surface of the second top plate. At this time, the cantilever steel beam body 4 is fixedly installed by means of the pre-embedded U-bolts and by using the first side clamp 1 and the second side clamp 2.

[0046] To further enhance the stability of the first side clamp 1 and the second side clamp 2 after fixing the cantilever steel beam body 4, several first through holes 112 are provided on the first top plate 11, and correspondingly, several second through holes 212 are also provided on the same side of the second top plate 21. By using bolts to pass through one of the overlapping first through holes 112 and one of the overlapping second through holes 212, the relative positions of the first side clamp 1 and the second side clamp 2 can be fixed, ensuring a secure installation of the cantilever steel beam body 4. When anchoring the cantilever steel beam body 4, two sets of mounting structures are provided at the ends, with at least one set of mounting structures on the outer side, achieving a secure anchoring of the cantilever steel beam body 4.

[0047] The adjustable cantilever steel beam installation structure for building scaffolding provided in this embodiment can stably anchor the main body 4 of the cantilever steel beam by using U-bolts pre-embedded in the concrete floor slab and adjustable first side clamps 1 and second side clamps 2 on both sides. The screws on both sides of the U-shaped positioning component, i.e., the U-bolt 3, pass through the first side clamp 1 and the second side clamp 2 respectively. By adjusting the distance between the first side clamp 1 and the second side clamp 2, they are made to abut against both sides of the web of the main body 4 of the cantilever steel beam, and then tightened with nuts to achieve stable positioning and installation of the cantilever steel beam.

[0048] The adjustable cantilever steel beam installation structure for building scaffolding provided in this embodiment utilizes the adjustable cooperation of U-bolts and the first side clamp 1 and the second side clamp 2 to adjust the spacing between them, thereby accommodating cantilever steel beams of different widths. This not only makes installation and operation flexible and convenient but also expands the range of applications. Furthermore, the first side clamp 1 and the second side clamp 2 respectively abut against both sides of the web of the cantilever steel beam body 4, providing a more stable anchorage to the cantilever steel beam body and enhancing its stability.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
