Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, and more specifically, to an edge protection structure for building construction. Background Art

[0002] At present, the edge protection used in construction mostly adopts finished protective fences. During installation, it is necessary to drill holes on the floor slab (or anti-slope) of the building edge, and use anchor bolts to fix it to the concrete structure through the reserved holes at the bottom of the vertical poles of the finished protective fence.

[0003] The currently common finished protective enclosure edge protection measures require a large one-time procurement investment, and drilling holes in the concrete can easily hit the structural steel bars, affecting the structural stress. In addition, the drilling workload is large, which can easily cause construction workers to cut corners and the number of bottom anchor bolts is insufficient, which in turn creates a greater safety hazard for the edge protection. Utility Model Content

[0023] Various embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. In each of the accompanying drawings, the same elements are represented by the same or similar reference numerals. For the sake of clarity, the various parts in the accompanying drawings are not drawn to scale.

[0024] The utility model provides a construction edge protection structure, see Figures 1 to 3 The construction edge protection structure includes a concrete counter-step 61 arranged at the edge of the building floor 6, and a scaffolding protection enclosure 1 installed on the concrete counter-step 61; wherein, a plurality of tension screws 2 are provided on the concrete counter-step 61; the scaffolding protection enclosure 1 includes a plurality of vertical poles 11 and a plurality of horizontal poles 12 vertically connected and fixed to each other, and the lower end of each vertical pole 11 is fixedly connected to the concrete counter-step 61 through the tension screws 2.

[0025] Specifically, the concrete anti-ridge 61 is a concrete structure set at the edge of the building floor, which is used to prevent people or objects from falling from the edge of the floor and plays a role in safety protection. The tension screw 2 is a tension screw that supports and fixes the formwork when the concrete anti-ridge 61 is poured. In specific implementation, the formwork is supported when the concrete anti-ridge 61 is poured, and the tension screw 2 is used to support and fix the formwork. After the concrete anti-ridge 61 is poured and cured, the formwork is removed, and the tension screw 2 is no longer removed, but retained as a connecting and fixing part of the scaffolding protective enclosure 1. In this way, there is no need to drill holes and set anchor bolts on the building floor 6 structure to fix the protective enclosure, which saves construction costs and improves construction efficiency. At the same time, it will not cause damage to the concrete structure of the building floor 6, and improves the safety of the construction of the edge protection structure.

[0026] The vertical poles 11 and the horizontal poles 12 of the scaffolding protection enclosure 1 are both scaffolding steel pipes, and the vertical poles 11 and the horizontal poles 12 are fixedly connected by scaffolding fasteners 13. The materials used in the manufacture of the scaffolding protection enclosure 1 are scaffolding steel pipes and scaffolding fasteners commonly used in construction. The materials are easy to obtain and the assembly is simple. After the construction is completed, the scaffolding protection enclosure 1 is dismantled, and the scaffolding steel pipes and scaffolding fasteners 13 can be reused, thereby reducing the construction cost. The scaffolding fasteners 13 are right-angle fasteners, that is, cross fasteners, so that the horizontal poles 12 and the vertical poles 11 can maintain a cross-shaped vertical cross-fixed connection after being connected, prevent relative rotation, and enhance the firmness and reliability of the scaffolding protection enclosure 1.

[0027] The lower end of the vertical pole 11 is fixedly connected to the inner side of the concrete anti-ridge 61 through the tension screw 2. Preferably, the lower end face of the vertical pole 11 abuts against the concrete floor surface of the building floor 6. The scaffolding protection enclosure 1 is set on the inner side of the concrete anti-ridge 61, which is convenient for the lower end of the vertical pole 11 to be connected and fixed with the tension screw 2, which is convenient for operation during installation and improves construction safety. At the same time, the lower end of the vertical pole 11 abuts against the concrete floor surface of the building floor 6, which can provide better support. After the tension screw 2 is connected to the vertical pole 11, it is only necessary to limit the vertical pole 11 from tilting.

[0028] Furthermore, one end of the tension screw 2 extending out of the inner side of the concrete anti-ridge 61 is threaded with a nut 4, and a clamping piece 3 is sleeved on the tension screw 2, and the clamping piece 3 is located between the nut 4 and the concrete anti-ridge 61; the lower end of the vertical pole 11 is arranged on one side of the tension screw 2, and the other side of the tension screw 2 is provided with a short steel pipe rod 5 parallel to the vertical pole 11, and the clamping piece 3 can be pressed by screwing the nut 4, and the clamping piece 3 presses and fixes the vertical pole 11 and the short steel pipe rod 5 on the inner side of the concrete anti-ridge 61. Through the above arrangement, when the vertical pole 11 is connected to the inner side of the concrete anti-ridge 61 through the tension screw 2, there is no need to open a hole on the vertical pole 11 to connect with the tension screw 2, and only a short steel pipe rod 5 with the same diameter as the vertical pole 11 needs to be provided as an auxiliary connecting piece to complete the installation and fixation of the vertical pole 11. Among them, the steel pipe short rod 5 is made of scaffolding steel pipe. During the specific implementation, a certain length of the waste scaffolding steel pipe can be cut and used as the steel pipe short rod 5. In this embodiment, the clamping piece 3 is a mountain-shaped clamp, which has two arc-shaped grooves and a through hole in the middle for passing the tension screw 2. The mountain-shaped clamp is sleeved on the tension screw 2 through the middle through hole. The two arc-shaped grooves of the mountain-shaped clamp are clamped on the vertical pole 11 and the steel pipe short rod 5. Screwing the nut 4 pushes the mountain-shaped clamp to move toward the direction of the concrete anti-ridge 61, so that the mountain-shaped clamp presses the vertical pole 11 and the steel pipe short rod 5 on the inner side of the concrete anti-ridge 61. In this embodiment, the nut 4 is an anti-loosening nut to prevent the nut from loosening during use and improve the safety of the edge protection structure. In other alternative embodiments, an anti-loosening measure of an ordinary nut plus a spring washer can also be adopted to prevent the nut from loosening during use.

[0029] In the scaffolding protection enclosure 1, the spacing between the vertical poles 11 is an integral multiple of the spacing between the tension screws 2 on the concrete counter-ridge 61, so that the lower end of each vertical pole 11 of the scaffolding protection enclosure 1 can correspond to the position of the tension screws 2 remaining after the concrete counter-ridge 61 is cast. After the floor construction is completed, the scaffolding protection enclosure 1 is dismantled, the vertical poles 11, the crossbars 12 and the scaffolding fasteners 13 are reused, and then the excess part of the tension screws 2 on the concrete counter-ridge 61 protruding from the wall surface is cut off.

[0030] In summary, the construction edge protection structure provided by the utility model installs the scaffolding protection fence composed of multiple vertical poles and horizontal poles on the concrete anti-slope at the edge of the building floor through the tension screw rods to form a stable edge protection structure, thereby achieving the effect of protecting the edge of the building floor. Compared with the existing use of finished protective fences as edge protection measures, the construction cost of the construction edge protection structure is lower, the impact of drilling holes on the concrete structure of the building floor on the structural safety is avoided, the cost of manual drilling is saved, and the construction cost is lower.
