Description

A honeycomb hole profiled steel plate-concrete prefabricated slab

technical field

The utility model relates to a prefabricated board, in particular to a honeycomb hole profiled steel plate-concrete prefabricated board used in the construction field.

Background technique

In recent years, in order to accelerate the development of housing industrialization, my country has issued various policies to vigorously encourage the research and development of various prefabricated structural systems. Compared with cast-in-place concrete components, prefabricated components are easy to manufacture, fast in construction, reduce formwork and wet work, shorten construction period, and be more environmentally friendly. They have huge development potential and wide application space.

At present, there are various types of prefabricated panels used in floor slabs, each with its own advantages and disadvantages. With the continuous development of the construction industry, the requirements for the floor slabs of residential buildings are also constantly increasing. Due to the complex structure and heavy weight of traditional prefabricated components, they do not meet the requirements of simple fabrication and fast construction. If the self-weight of prefabricated components is reduced, the usual practice is to arrange prestressed steel bars in the prefabricated components. The construction process of this method is more complicated, and it is not easy to guarantee the quality of prefabricated components. It is temporarily difficult to realize mass industrial production. Prefabricated panels with steel trusses as the skeleton can make up for the above shortcomings to a certain extent, but the strength of prefabricated components is greatly affected by the height of steel trusses. If the span of the plate is large, the height of the truss and the size of the steel bar are also required to be increased accordingly, and the overall cost will increase, making it uneconomical to adopt this form.

Contents of the invention

The purpose of the utility model is to provide a honeycomb hole profiled steel plate-concrete prefabricated plate with light weight, no need to dismantle the bottom formwork, good integrity and reasonable force.

In order to achieve the above-mentioned technical purpose, the honeycomb-hole profiled steel plate-concrete prefabricated panel of the present utility model comprises a honeycomb-hole profiled steel plate and a concrete bottom plate, and the honeycomb-hole profiled steel plate is a corrugated thin steel plate bent into a "several" shape Both sides of the honeycomb profiled steel plate are provided with lower flanges, and a plurality of evenly distributed hollow holes are opened on the honeycomb profiled steel plate, and the lower flange of the honeycomb profiled steel plate is integrated with the concrete bottom plate.

The evenly distributed hollow holes of the honeycomb profiled steel plate are hexagonal holes or round holes; when the honeycomb profiled steel plate is pressed and formed, it should be ensured that the web holes correspond to each other, and the web holes pressed by the honeycomb profiled steel plate There are transverse steel bars or pipelines in the middle; the lower flange of the honeycomb-hole profiled steel plate is completely wrapped by the concrete bottom plate, and the distance between the lower flange of the honeycomb-hole profiled steel plate and the bottom plate is not less than the thickness of the concrete bottom plate; the honeycomb hole pressure The lower flange of the shaped steel plate exceeds the edge of the concrete bottom plate by a certain distance to facilitate the splicing with the prefabricated panels, and the edges on both sides of the concrete bottom plate at the splicing position are provided with downward-sloping grooves.

Beneficial effect:

The utility model protrudes from the lower flange of the concrete floor through the honeycomb hole profiled steel plate and the edges on both sides of the concrete floor are provided with downwardly inclined grooves to realize the rapid assembly of prefabricated panels and enhance the splicing effect at the splicing place; the honeycomb hole profile The holes in the steel plate can save the amount of steel without reducing the overall strength, reduce its own weight, improve the integrity of concrete and profiled steel plate, and also facilitate the insertion of pipelines and steel bars; the honeycomb hole profiled steel plate can be used as a prefabricated concrete floor Provide bending rigidity, which can reduce the weight of prefabricated panels.
