Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete precast blasting point technology, and in particular to a precast blasting point structure. Background Technology
[0002] Most existing finished blasting points are cylindrical blasting points made of concrete. Before pouring, the blasting points are fixed to the slab surface with nails and poured together with the main body.
[0003] Currently, precast concrete blasting points are mostly fixed to the formwork with nails before pouring. This practice seriously affects the efficiency of formwork removal and causes additional damage during removal, reducing the reuse rate of the formwork. Furthermore, substandard concrete blasting points can reduce the concrete strength of the floor slab, affecting the building's structural integrity and safety. Finally, through-cracks are prone to form at the joint between the precast concrete blasting points and the cast-in-place concrete, severely compromising the self-waterproofing properties of the concrete slab surface. Utility Model Content
[0004] The purpose of this utility model is to provide a precast blasting point structure to alleviate the technical problem that precast concrete blasting points in the prior art are not easy to dismantle and cannot be used multiple times.
[0005] The finished blasting point structure provided by this utility model includes: a foot frame component, a leveling steel plate, and a connecting nut;
[0006] The scaffolding component includes a first upright post, which has a threaded section.
[0007] The leveling steel plate is connected to a second upright, and the end of the second upright is fixed with the connecting nut;
[0008] All connecting nuts are threadedly connected to the threaded section.
[0009] In an optional implementation,
[0010] The leg structure includes multiple leg legs;
[0011] All of the aforementioned tripod legs are connected to the first upright.
[0012] In an optional implementation,
[0013] The leveling steel plate is provided with a second upright on the side near the leg of the scaffold.
[0014] In an optional implementation,
[0015] A lifting ring is provided on the side of the leveling steel plate away from the second upright.
[0016] The precast blasting point structure provided by this utility model is assembled by setting a threaded section on the first upright in the support frame component, connecting the leveling steel plate to the second upright, and setting a second threaded section on the second upright. The connecting nut is threadedly connected to the threaded section and the second threaded section. Furthermore, the setting of the connecting nut allows the first and second uprights to be disassembled and assembled at will. The second upright of different heights can be selected according to different plate thicknesses, which alleviates the technical problem in the prior art that precast concrete blasting points are not easy to disassemble and cannot be used multiple times.
