Description

Prefabricated floor of assembled
Technical Field
The utility model relates to a building technical field especially indicates an assembled prefabricated floor.
Background
Along with economic construction and social development, steel structure buildings are applied more and more. At present, in most steel structure buildings, the floor slab is a profiled steel plate concrete floor slab or a steel bar truss floor bearing plate cast-in-place concrete floor slab. The profiled steel plate concrete floor is formed by directly pouring concrete on a profiled steel plate serving as a construction template of the concrete floor, and has the advantages of high installation speed, simplicity and convenience in operation and the like. Profiled steel plate concrete floor slabs are divided into a combined type and a non-combined type. The profiled steel sheet is used for replacing part of the bottom reinforcing steel bars of the floor slab to participate in the stress of the floor slab. However, when such a floor slab is used, the profiled steel sheets must be protected against fire, and the expensive cost of fire protection makes the composite floor slab less applicable. The non-combined floor slab is the same as the steel bar truss floor bearing plate, and only the profiled steel sheet is used as a construction template, so that the waste is caused economically, and the cost is higher indirectly. In addition, for aesthetic and practical purposes, the profiled steel sheet concrete floor slab must be subjected to secondary suspended ceiling, is not in accordance with the idea of energy-saving and low-carbon building, and is difficult to meet the cost control requirement of developers. The concrete floor slab is directly adopted, so that the method is economical, the traditional construction method is to directly set up a scaffold and then install a template, but the method has large workload and long construction period.

In order to solve the technical problem, the utility model provides a following technical scheme:
the utility model provides an assembled precast floor slab, includes concrete floor slab main part, assembled precast floor slab still includes H shaped steel, with the reinforcing bar net piece has been laid as the fulcrum to the lower flange of H shaped steel to form concrete floor slab main part.
Wherein, the web plate of the H-shaped steel is provided with a hole.
And L-shaped cover plates are arranged at two ends of the H-shaped steel.
The H-shaped steel is a hot-rolled H-shaped steel beam or a welded H-shaped steel beam.
Wherein, the shape of the hole is rectangle, square, ellipse or round.
The L-shaped cover plate is integrally formed or welded by steel plates.
The upper end of the abutted seam of the concrete floor main body is welded and fixed with the steel beam through a connecting plate, and then fine stone concrete is poured and filled or is covered by a refractory plate.
The utility model discloses an above-mentioned technical scheme's beneficial effect as follows:
in the scheme, the main components of the fabricated precast floor slab are all prefabricated components, so that the fabricated precast floor slab is simple and convenient to connect, easy to install, low in manufacturing cost, convenient for modular manufacturing and high in industrialization degree; when the prefabricated floor slab is installed, multiple layers of construction can be carried out simultaneously, and the construction efficiency is high; concrete floor main part bottom surface is level and smooth, need not secondary furred ceiling, can save partly interior space, in addition, can provide the no roof beam interior space of very large-span, cuts apart the convenient condition of providing for indoor flexibility.

Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3, the embodiment of the utility model provides an assembled precast floor slab, including concrete floor main part 2, assembled precast floor slab still includes H shaped steel 1, with reinforcing bar net piece has been laid as the fulcrum to H shaped steel 1's bottom flange to form concrete floor main part 2, wherein, reinforcing bar net piece is ordinary reinforcing bar net piece or adds the reinforcing bar net piece of prestressing steel.
As shown in fig. 1, a hole 3 is formed in a web plate of the H-shaped steel 1, so that water, electricity and air-conditioning pipes can pass through the hole, and the inner space of the fabricated precast floor slab is utilized to the maximum extent.
As shown in fig. 1, L-shaped cover plates 4 are arranged at two ends of the H-shaped steel 1.
The H-shaped steel 1 is a hot-rolled H-shaped steel beam or a welded H-shaped steel beam.
Wherein, the shape of the hole 3 is rectangle, square, ellipse or circle.
The L-shaped cover plate 4 is an integrally formed angle steel or steel casting, and may also be formed by welding steel plates.
