Description

Technical Field

[0001] The utility model relates to the technical field of house construction, in particular to an elevator shaft steel bar protection mesh installation structure. Background Art

[0002] In the construction of housing construction projects, the elevator shaft is a special part that is prone to safety accidents and difficult to control in quality. The traditional practice is usually to set up ground-type steel pipe scaffolding or I-beam cantilever scaffolding according to the construction progress. When constructing each floor of the elevator shaft shear wall structure, it is necessary to lay the template and install the operating platform. A hard protection is set every 3 floors below the construction floor, and the elevator shaft protection door is installed layer by layer.

[0003] After the steel protection mesh is installed, multiple layers of cover plates are stacked and fixed with rivets. This structure will result in a lack of structural connection between the cover plate and the steel protection mesh, which poses a certain degree of safety hazard in terms of protection. At the same time, if a safety accident occurs or objects fall onto the cover plate, considering the construction environment, it is difficult to arouse the vigilance of surrounding workers, and it also makes it difficult for surrounding construction workers to respond to the problem in the first time.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and an elevator shaft steel bar protective mesh installation structure is proposed. Summary of the invention

[0005] The purpose of the utility model is to provide an elevator shaft steel bar protection mesh installation structure to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an elevator shaft steel bar protective mesh installation structure, comprising an elevator shaft main body and a connecting component, a collision sensing alarm is installed on one side of the inner wall of the elevator shaft main body, and a protective mesh main body is arranged in the middle of the interior of the elevator shaft main body, the connecting component is installed on the surface of the protective mesh main body, and a supporting beam is arranged below the protective mesh main body, and plywood is laid on the top of the protective mesh main body through the connecting component, the connecting component comprises a connecting block, a sleeve, an assembly hole, a nut and a screw, a sleeve is arranged in the middle of the connecting block, and assembly holes are vertically opened on the left and right sides of the connecting block, and a nut is inlaid in the interior of the assembly hole, and a screw is vertically penetrated through the middle of the nut.

[0007] Furthermore, the collision sensing alarm is movably mounted on the inner wall surface of the elevator shaft body, and the bottom sensing structure of the collision sensing alarm is attached to the surface of the plywood.

[0008] Furthermore, the longitudinal and transverse spacing of the protective mesh body is arranged in an equidistant structure, and the longitudinal and transverse ends of the protective mesh body are arranged in a 90-degree bending structure, and the longitudinal and transverse steel bars of the protective mesh body are fully tied with wire to ensure the stability of the entire protective mesh body.

[0009] Furthermore, the protective mesh body and the supporting beams are cast in the inner wall of the elevator shaft body, and the protective mesh body and the supporting beams are arranged in parallel with each other, and the supporting beams are attached to the bottom surface of the protective mesh body.

[0010] Furthermore, the inner diameter structural dimensions of the sleeve match the longitudinal and transverse steel bar surface structural dimensions of the protective mesh body, and the sleeve and the protective mesh body are slidably connected.

[0011] Furthermore, the screw and the nut are threadedly connected, and the nut is arranged inside the connecting block.

[0012] Furthermore, the screws are threadedly connected to the plywood, and the structural dimensions of the plywood are smaller than the inner wall dimensions of the elevator shaft body.

[0013] Furthermore, the connecting components are arranged in an equidistant array in the middle of the protective mesh body, and the plywood and the connecting components are movably connected.

[0014] The utility model provides an elevator shaft steel bar protection mesh installation structure, which has the following beneficial effects:

[0015] 1. The utility model has a plurality of connecting components arrayed on the surface of the protective mesh body. When the construction workers lay the plywood, the plywood is placed flat on the top surface of the connecting block, and then the screws are screwed into the surface of the plywood from top to bottom in the vertical direction, and then enter the inside of the assembly hole and screwed into the nut, so that the protective mesh body, the connecting component and the plywood can be stably connected. By using the above structure, on the one hand, the plywood and the protective mesh body can be connected to each other, which can prevent the plywood from slipping on the surface of the protective mesh body. On the other hand, the use of the above structure also provides convenience for subsequent dismantling operations. Only an electric screwdriver is needed to quickly separate and dismantle the plywood from the surface of the connecting component. In addition, the structure of the connecting component can be reused after the entire structure is dismantled, avoiding waste of materials.

[0016] 2. The utility model installs a collision sensing alarm on the inner wall of the elevator shaft body, and makes the bottom of the collision sensing alarm contact with the surface of the laid plywood, so that when an accident occurs or an object falls onto the surface of the plywood, the vibration and impact generated by the collision will immediately trigger the collision sensing alarm and generate sound and light prompts. By using the above structure, it is possible to quickly prompt surrounding workers, thereby providing an immediate warning for problems that occur, so that construction workers can respond in time to prevent the problem from expanding. In addition, by arranging a supporting beam at the bottom of the protective mesh body, it is possible to further assist the protective mesh body in providing effective structural support, so that the entire structure can maintain sufficient safety protection. The use of the simple structure of the supporting beam saves costs and effectively simplifies subsequent demolition operations. BRIEF DESCRIPTION OF THE DRAWINGS

The inner diameter structural dimensions of the nail 405 and the sleeve 402 match the structural dimensions of the longitudinal and transverse steel bar surfaces of the protective mesh body 3, and the sleeve 402 is slidably connected to the protective mesh body 3, the screw 405 is threadedly connected to the nut 404, and the nut 404 is arranged inside the connecting block 401, the screw 405 is threadedly connected to the plywood 6, and the structural dimensions of the plywood 6 are smaller than the inner wall dimensions of the elevator shaft body 1. When the construction workers lay the plywood 6, they place the plywood 6 flat on the top surface of the connecting block 401, and then screw the screws 405 into the surface of the plywood 6 from top to bottom in the vertical direction, and then enter the inside of the assembly hole 403 and screw them into the nut 404, so that the protective mesh body 3, the connecting component 4 and the plywood 6 can be stably connected.

[0026] like Figures 1 to 6 As shown, the collision sensing alarm 2 is movably installed on the inner wall surface of the elevator shaft main body 1, and the bottom sensing structure of the collision sensing alarm 2 is attached to the surface of the plywood 6, the longitudinal and transverse spacing of the protective mesh main body 3 is arranged in an equidistant structure, and the longitudinal and transverse ends of the protective mesh main body 3 are arranged in a 90-degree bending structure, and the longitudinal and transverse steel bars of the protective mesh main body 3 are fully tied with wire to ensure the stability of the entire protective mesh main body 3, the protective mesh main body 3 and the supporting beam frame 5 are cast in the inner wall of the elevator shaft main body 1, and the protective mesh main body 3 and the supporting beam frame 5 are The frames 5 are arranged in parallel with each other, and the supporting beam frames 5 are attached to the bottom surface of the protective mesh body 3.

[0027] In summary, if Figures 1 to 6As shown, the elevator shaft steel bar protection mesh installation structure, when in use, first the entire device structure can be operated synchronously with the construction of the elevator shaft main body 1, and the support structure is installed during the construction process. First, the mold is matched according to the drawing size. The length is the net length of the opening minus twice the thickness of the template, and the height is the height of the concrete slab of the floor. Then, grooves are made in accordance with the structural dimensions of the longitudinal and transverse steel bars of the protection mesh body 3, and the side panels are made into a comb shape. For the elevator shaft with shear wall structure, grooves are made directly on the upper end of the shear wall formwork according to the structural distance between the support beam 5 and the protection mesh body 3. After the side formwork is processed, it is positioned and reinforced according to the position of the opening. After the fixing is completed, a release agent is applied;

[0028] Then put the supporting beam 5 and the steel bars of the main body 3 of the protective mesh that have been prepared into the grooves opened in the side mold, set them in two directions, and tie them fully with wire. Set elbows at both ends of the main body 3 of the protective mesh that have been prepared, anchor both ends into the supports, and let the elbows point downward. Use galvanized iron wire to tie the intersections of the longitudinal and transverse steel bars into a figure-eight buckle, and press the end wire of the binding to the bottom of the shaft. Do not skip the buckle during the binding. In this process, several connecting components 4 can be simultaneously sleeved on the surface of the main body 3 of the protective mesh. If there are no beams around the reserved opening, directly put the two-way lower steel bars of the floor slab into the grooves and tie them. The protective steel bars are the full-length lower bars of the floor, and rubber plugs should be added to their roots to facilitate rust prevention during removal. The rubber plugs should be firmly fixed to prevent deviation during concrete pouring.

[0029] After the flat steel bars and the support system have passed the supervision and acceptance, the concrete pouring construction is carried out. The concrete around the reserved opening is vibrated and compacted to increase the bond strength of the concrete to the steel bars and maximize safety. When the concrete solidifies and reaches the required structural strength, the construction personnel can lay the plywood 6 on the top surface of the connecting block 401, and then use screws 405 to screw into the surface of the plywood 6 in turn, and then screw into the assembly hole 403 inlaid with the nut 404, so that the protective mesh body 3, the connecting component 4 and the plywood 6 are connected and fixed to each other, and finally the bottom of the collision sensing alarm 2 is attached to the surface of the plywood 6 and installed on the side wall surface of the elevator shaft body 1.
