Technical Field
The utility model relates to a building constructs the accessory field, specifically is a hollow superstructure combination mandrel banding device of building.
Background
The hollow floor is a cast-in-situ reinforced concrete hollow floor; also called as a cast-in-situ beamless hollow floor, and the hollow beamless floor is formed by cast-in-situ after a core mould product is installed. The hollow floor includes reinforcing steel bar, concrete and core mold embedded between the upper and lower ribbed reinforced concrete beams.
In some cast-in-place steel disc concrete hollow floor system technologies, a square core mold is adopted and placed on a template bottom plate surface reinforcing steel bar or in a dense rib beam grid laid by a hollow floor system, integral or single anti-floating is made, upper rib is laid and bound, then concrete is poured to form the hollow floor system, however, after the formwork of the existing hollow floor is removed, the phenomena of steel bar exposure, honeycomb holes, cracking, water seepage and the like on the bottom surface of the concrete floor generally exist, so that the hollow floor has serious hidden danger of construction quality, the main reason in this respect is that the filling core mould of the hollow floor is a square core mould, the concrete can not flow to the middle position of the square core die when the concrete is poured and vibrated, so that the bottom surface of the concrete floor slab is not compact, the engineering quality hidden trouble exists, therefore, a strip-shaped core mold is designed, and a square core mold is formed by two strip-shaped core molds, so that the problems are solved; however, common core mold products in the market at present comprise organic materials and inorganic materials, the organic materials are mostly polyphenyl, the inorganic materials are cement fibers and gypsum, the core mold products made of polyphenyl materials have poor fire resistance, the polyphenyl materials release harmful gases when a fire disaster occurs, potential safety hazards exist, the core mold made of cement fibers or stone materials has poor strength, the loss rate of the core mold in the transportation and installation processes is high, and the dead weight of the materials is large, so that the transportation cost, the material transportation cost and the installation cost are increased.
In recent years, metal core mold products are also available on the market, metal materials have the characteristic of high strength, most of the metal core mold products are complicated in manufacturing process, a large amount of labor is consumed for transportation and installation, the manufacturing cost and the installation cost are improved, part of the metal core mold products are divided into two parts or a plurality of parts to form a combined core mold in order to reduce the transportation cost, the combined core mold needs to be combined on a construction site, the conventional core mold combination method adopts screw punching combination fixing, welding fixing and the like, but the cost is relatively high, the screw punching fixing labor cost is high, the firmness of the metal combined core mold cannot be guaranteed, the welding fixing can cause high-temperature deformation, welding spots are easy to rust and the like.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a combination mandrel banding device that equipment is simple, the structure is firm to solve prior art not enough.
The utility model adopts the following technical scheme:
the utility model provides a hollow superstructure combination mandrel banding device of building, includes the body, its characterized in that: the body comprises two sets of outer blank pressing and two sets of interior blank pressing that the longitudinal symmetry set up, outer blank pressing sets up the one side at the body, interior blank pressing sets up the opposite side at the body, the tip of outer blank pressing is equipped with outer blank pressing cramp, the tip of interior blank pressing is equipped with interior blank pressing cramp, outer blank pressing is the type structure that turns up, interior blank pressing is the arc structure of raising upward.
Furthermore, the outer pressure edge is evenly provided with a plurality of fastening screw holes, and the body is provided with screw holes aligned with the fastening screw holes evenly arranged on the outer pressure edge.
Furthermore, one end of the outer pressing edge is provided with a lap joint section, and the distance between the lap joint section and the body is greater than the distance between the outer pressing edge and the body.
Compared with the prior art, the beneficial effects of the utility model are that:
