Background
The aluminum alloy template has the advantages of light weight, flexible disassembly and assembly, high rigidity, long service life, large plate surface, few abutted seams, high precision, flat and smooth concrete surface after pouring, low mechanical dependence degree of construction, capability of effectively reducing labor and material cost, wide application range, low maintenance cost, high construction efficiency, high recovery value and the like, and is increasingly widely applied to the field of buildings.
When the aluminum alloy template adopts a pull rod type reinforcing system, opposite-pulling holes need to be formed in advance during pre-assembly so as to facilitate field construction. In the construction process, because the conditions of variable cross section of a shear wall, improper reinforcement binding of a construction site and the like exist inevitably, the position of the counter-pulling screw rod and the reinforcement is often collided, so that the original hole position of the hole is deviated, and at the moment, the counter-pulling hole is machined at the required point position again in the site by the conventional method. Meanwhile, before concrete pouring, the original hole is blocked in time, so that the condition that the concrete overflows from the original counter-pulling hole to cause slurry leakage and influence on the final finished surface poor finish quality is avoided.
Disclosure of Invention
The utility model discloses a solve the aluminum alloy template that adopts pull rod formula to consolidate the system and need carry out timely shutoff problem to original hole because of opening the counter-bore again, provide a special hole plugging device of aluminum alloy template.
The utility model discloses a realize through following technical scheme: the utility model provides a special hole plugging device of aluminum alloy template, including shutoff screw and shutoff nut, the shutoff screw includes the lead screw, the one end of lead screw is connected with the screw head perpendicularly, one side that the screw head is connected with the lead screw is the plane, the opposite side of screw head is the cambered surface, the maximum thickness of screw head is 4 ~ 6 millimeters, the cover is equipped with the packing ring on the lead screw, the packing ring adopts SBS waterproofing membrane processing to form, the thickness of packing ring is 1 millimeter, packing ring one side is connected with the plane contact of screw head, packing ring opposite side contact be connected with the original trompil department of aluminum alloy template face all around.
Further, the screw head faces the concrete pouring side.
Further, the length of the screw rod is 3-5 mm larger than the sum of the thickness of the plugging nut and the thickness of the aluminum alloy template.
The diameter of one side of the plane of the screw head is 8-10 mm larger than that of the screw rod, and the outer diameter of the gasket is the same as that of one side of the plane of the screw head.
Furthermore, the plugging screw and the plugging nut are made of any one of PVC or plastic materials.
Compared with the prior art, the utility model beneficial effect who has is:
the utility model can effectively block the counter-pulling holes of the aluminum alloy template which are not in line with the positions, and solves the problem of slurry leakage possibly caused by the existence of the original counter-pulling holes in the concrete pouring process; meanwhile, the screw head of the plugging screw faces the concrete side in an arc-shaped surface, and the maximum thickness of the screw head is 4-6 mm, so that the relative smoothness of the concrete forming surface after plugging is finished is ensured, and the appearance quality of the surface after concrete forming is greatly improved. Furthermore, the utility model discloses material in shutoff screw and the shutoff nut all adopted PVC or plastic material, feasible the utility model discloses light easy operation of structure and green can not take place the condition such as corrosion.
