Description

Technical Field

[0001] The utility model relates to the technical field of transportation or assembly of building components, in particular to a cable-connected wall device for a cantilevered unloading platform of an assembled steel structure building. Background Art

[0002] The cantilever unloading platform is a work platform used for high-altitude unloading. Excess construction materials and construction waste in high-rise building construction can be efficiently suspended from the cantilever unloading platform to the ground or lower floors. Its load-bearing structure includes two main beams extending to the building floor slab of the floor and four inclined steel wire ropes connected to the upper floors.

[0003] At present, the anchor rings of the main and auxiliary steel wire ropes of most cantilever unloading steel platforms are round steel pull rings, which are pre-buried in the main structure. In the traditional reinforced concrete structure construction process, the unloading platform steel wire rope tie points are set with embedded parts and poured in the concrete. At present, the country is vigorously developing prefabricated steel structure buildings. Most prefabricated steel structure buildings are steel frame structures with lightweight partition walls or glass curtain walls as exterior walls. It is difficult to set the anchor points of the unloading platform steel wire rope tie during construction, because the exterior walls of prefabricated steel structure buildings are not load-bearing structures and have low strength. Anchoring the inclined steel wire rope on them will pose a safety hazard (one is to cause the cable to fall off, and the other is to cause the exterior wall to be damaged). Utility Model Content

[0004] The utility model provides a cable wall connecting device for a cantilevered unloading platform of an assembled steel structure building.

[0005] The technical problem to be solved is that the outer wall strength of the prefabricated steel structure building is relatively low, and anchoring the cables of the cantilevered unloading platform on it will pose a safety hazard.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: a cable-connected wall device for a cantilevered unloading platform of an assembled steel structure building, wherein the outer wall where the unloading platform is located has a steel beam parallel to the outer wall for supporting the floor slab, and one of the steel beams close to the outer wall is recorded as a wall-supported steel beam, and the cable-connected wall device includes a tie beam buckle buckled on the wall-supported steel beam and penetrating the outer wall of the building, a wall-mounted plate attached to the outer side of the outer wall, and a double-ear plate fixed on the wall-mounted plate and used for installing the cable;

[0007] The tie beam buckle is U-shaped, the wall-facing steel beam is located inside the tie beam buckle, and the two legs of the tie beam buckle penetrate the outer wall and the wall plate and are locked by nuts;

[0008] The double-ear plate is arranged vertically, and bolts or pins for attaching the cable are horizontally passed through the double-ear plate.

[0009] Furthermore, the tops of the double-ear plates are connected as a whole through a horizontally arranged baffle plate, and the baffle plate is fixedly connected to the wall plate.

[0010] Furthermore, the double-ear plate, the baffle plate, and the wall plate are fully welded on both sides to form an integral prefabricated component.

[0011] Furthermore, after the tie beam buckle penetrates the exterior wall and the wall panel, it is locked by a double nut with a steel gasket. The thickness of the steel gasket is not less than 10 mm, and the length of the part of the tie beam buckle extending out of the double nut is not less than 3 buckles.

[0012] Furthermore, the tension beam buckle extends out of the outer wall through a hole that is reserved or excavated on site, and when the hole is a reserved hole, a PVC sleeve is arranged in the hole to prevent the hole from collapsing.

[0013] Furthermore, the beam buckle passes through the hole in the outer wall, and the hole located above is recorded as the under-slab hole. The under-slab hole extends horizontally under the floor away from the outer wall to form an installation groove for the beam buckle to be placed in. The beam buckle is formed by bending round steel, and the opening width of the installation groove located on the side of the wall-mounted steel beam away from the outer wall is not less than the diameter of the beam buckle.

[0014] Compared with the prior art, the cable-connected wall device for a cantilevered unloading platform of an assembled steel structure building has the following beneficial effects:

[0015] In the utility model, the cable of the cantilever unloading platform is connected to the building by using a tie-beam buckle that is buckled on the steel beam and the outer wall at the same time. The main tension of the cable acts on the steel beam instead of the outer wall of the building. Most of the tension is borne by the steel beam grid of the entire floor. Even if the outer wall of the building is a completely decorative wall panel, there will be no safety hazard. At the same time, the main components are only two parts. The tie-beam buckle goes from the installation groove around the steel beam to the outside of the wall and then buckles with the wall panel to complete the installation. The installation and use are very simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In the figure, 1-steel beam against the wall, 2-tension beam buckle, 3-wall panel, 4-double ear plate, 5-installation groove. DETAILED DESCRIPTION

[0019] like Figure 1-2As shown, a cable-connected wall device for a cantilevered unloading platform for a prefabricated steel structure building, the outer wall where the unloading platform is located has a steel beam parallel to the outer wall for supporting the floor slab, and one of the steel beams close to the outer wall is recorded as a wall-supporting steel beam 1; that is, the location of the utility model is selective, and the utility model should be set at the outer wall position where the steel beam close to the outer wall of the building is selected according to the design drawing of the building floor slab. Of course, if it is difficult to find, a longer tension beam buckle 2 should be selected.

[0020] The cable-connected wall device comprises a tie beam buckle 2 buckled on a wall-mounted steel beam 1 and penetrating the outer wall of the building, a wall plate 3 abutting against the outer side of the outer wall, and a double-ear plate 4 fixed on the wall plate 3 and used for installing the cable;

[0021] The double-ear plate 4 is used here for rigidity considerations, because here, unlike the embedded parts, the external structure is independent.

[0022] The tie beam buckle 2 is U-shaped, the steel beam 1 against the wall is located inside the tie beam buckle 2, and the two legs of the tie beam buckle 2 penetrate the outer wall and the wall plate 3 and are locked by nuts;

[0023] The double-ear plate 4 is vertically arranged, and bolts or pins for attaching the cable are horizontally penetrated through the double-ear plate 4.

[0024] The top of the double-ear plate 4 is connected as a whole through a horizontally arranged baffle, and the baffle is fixedly connected to the wall plate 3. This can further increase the rigidity and block the sundries falling from the top.

[0025] The double-ear plate 4, the baffle plate, and the wall plate 3 are fully welded on both sides to form an integral prefabricated part. This can reduce the workload of installation. When installing, the two parts are buckled together and locked with nuts to complete the installation.

[0026] After the tie beam buckle 2 penetrates the exterior wall and the wall panel 3, it is locked by a double nut with a steel gasket. The thickness of the steel gasket is not less than 10 mm, and the length of the part of the tie beam buckle 2 extending out of the double nut is not less than 3 buckles.

[0027] The double nuts are used here to prevent loosening, and the sufficiently thick steel gaskets are used to prevent the wallboard 3 from being crushed.

[0028] The tension beam buckle 2 extends out of the outer wall through a hole that is reserved or excavated on site, and when the hole is a reserved hole, a PVC sleeve is arranged in the hole to prevent the hole from collapsing.

[0029] The beam buckle 2 passes through the hole in the outer wall, and the hole located above is recorded as the under-slab hole. The under-slab hole extends horizontally under the floor away from the outer wall to form an installation groove 5 for the beam buckle 2 to be placed in. The beam buckle 2 is formed by bending round steel, and the opening width of the installation groove 5 located on the side of the wall-mounted steel beam 1 away from the outer wall is not less than the diameter of the beam buckle 2.

[0030] The installation groove 5 here is used for the tie beam buckle 2 to bypass the wall steel beam 1. If the hole through which the tie beam buckle 2 passes through the outer wall is very thin and fits tightly with the tie beam buckle 2, then the length of the installation groove 5 should be ensured to be able to accommodate the horizontal part of the tie beam buckle 2. Of course, the actual hole excavated is thicker and does not require such a long installation groove 5.

[0031] A method for using a cable-connected wall device for a cantilevered unloading platform of an assembled steel structure building in this embodiment includes the following steps:

[0032] Step 1: Pass the tension beam buckle 2 through the outer wall;

[0033] Step 2: Buckle the wall plate 3 onto the tension beam buckle 2 and lock it with a nut;

[0034] Step 3: Install the cable.

[0035] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
