Description
Technical Field
The utility model belongs to the technical field of building engineering, especially, relate to a novel building concrete prefabricated plate.
Background
In recent years, assembly type buildings are the development direction of engineering construction, fine construction is adopted, energy is saved, pollution is reduced, and efficiency and quality can be improved. The prefabricated slab has low cost and simple construction, and is widely used as a bearing member of a floor or a roof in civil buildings such as houses.
When the prefabricated slab is manufactured, a hollow model is firstly nailed by wood plates, reinforcing steel bars are distributed at the hollow part of the model, the hollow part is filled with cement, and after the hollow part is dried, the wood plates are knocked off, and the prefabricated slab is remained. However, the existing concrete precast slab has the following problems: in the use process, the four corners of the prefabricated slab and the joint of the two prefabricated slabs are easy to crack, which not only influences the integrity of the floor structure, but also causes the problems of leakage and the like, and has great potential safety hazard.
Disclosure of Invention
The to-be-solved problem of the utility model is to provide a simple structure, prevent the fracture, prevent the collapse angle, connect firm novel building concrete prefabricated plate.
In order to solve the technical problem, the utility model discloses a technical scheme is: the utility model provides a novel building concrete precast slab, includes the plate concrete body, the plate concrete body extension degree direction is provided with row form through hole, and this plate concrete body internal four corners department is provided with vertical metal sleeve, the metal sleeve both ends are squarely, and the square sunken groove setting on embedding plate concrete body surface, this metal sleeve urceolus wall are provided with section of thick bamboo wall enclosure screen, and this metal sleeve is equipped with the angle bead that two reinforcing plates are constituteed towards four corners position, row form through hole top and below symmetry are provided with the crack control net.
The connecting plate is embedded into the connecting plate accommodating grooves of the two plate-shaped concrete bodies, and the connecting plate and the plate-shaped concrete bodies are connected and fixed by penetrating the metal sleeve through the connecting piece.
The four corners of the anti-cracking net are fixed on the metal sleeve.
Since the technical scheme is used, the utility model discloses the vertical metal sleeve that four corners department set up in the plate concrete body has the supporting role to whole, the section of thick bamboo wall enclosure net that the metal sleeve urceolus wall set up can improve the confined power of section of thick bamboo wall to the concrete, thereby improve the bearing capacity of whole prefabricated plate, the crack control net that row form through hole top and below symmetry set up is for having space and vertically and horizontally staggered's structure, consequently, fill the concrete between here, the net solid effect to the concrete has been realized, the constraint effect to the concrete each direction has been strengthened, the crack control effect of whole prefabricated plate has effectively been improved more.
The utility model discloses the metal sleeve both ends are squarely, and the square sunken groove setting on embedding plate concrete body surface, metal sleeve are equipped with the angle bead that two reinforcing plates are constituteed towards four corners position, and this design has the four corners position that does benefit to the protection plate concrete body, has avoided the condition of collapsing the angle fracture.
The utility model discloses in the connecting plate storage tank of two plate concrete body of connecting plate embedding, pass metal sleeve through the connecting piece and be connected connecting plate and plate concrete body fixedly, improved the firm degree of being connected between board and the board.
The utility model has the advantages that: has the advantages of simple structure, cracking prevention, corner collapse prevention and stable connection.
