Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building waterproof components, in particular to a prefabricated building roof concrete waterproof component. BACKGROUND

[0002] The roof is an important part of the building, bearing multiple functions. It is not only the uppermost covering part of the house, but also has a significant load-bearing role; in structure, the roof usually includes roof, insulation (heat insulation) layer and load-bearing structure three main parts; these components work together to ensure that the roof can withstand various natural forces and human loads, such as wind, rain, snow, etc. The load-bearing structure of the roof is usually a concrete building roof, which is usually poured by post-forming concrete with formwork, which can support the shape and structure of the concrete during pouring and hardening, ensuring the quality of the concrete structure.

[0003] However, the process of pouring concrete with post-forming formwork is complex, and if the formwork is not stable enough during construction, it is easy to collapse, which poses a serious threat to the safety of personnel on the construction site; the use of formwork also involves a large amount of material consumption and labor cost, further increasing the economic burden of construction. At the same time, as a modern building technology, prefabricated concrete slabs have gradually attracted attention in roof construction, which produces concrete components through factory prefabrication and then transports them to the construction site for assembly, greatly improving construction efficiency and reducing the time and labor demand for on-site work. However, prefabricated concrete slabs have also exposed some problems in practical application, especially the cracking problem at the joint between the slabs, which directly affects the waterproof performance of the roof and increases the difficulty and cost of later maintenance. SUMMARY

[0004] In view of the deficiencies in the prior art, the present application provides a prefabricated building roof concrete waterproof component to solve the problem of a large amount of formwork construction, which easily threatens the safety of personnel and consumes a large amount of materials and labor.

[0005] To achieve the above purpose, the basic scheme of the present application is as follows: a prefabricated building roof concrete waterproof component, comprising:

[0006] a plurality of preformed roof corner pieces;

[0007] a plurality of preformed middle connecting pieces, one side of the middle connecting piece being connected with one side of the roof corner piece;

[0008] a plurality of preformed end plate pieces, one side of the end plate piece being connected with the side of the middle connecting piece away from the roof corner piece;

[0009] The middle connecting piece and the roof corner piece, and the middle connecting piece and the end plate piece are provided with a clamping structure.

[0010] The roof corner piece, the middle connecting piece and the end plate piece are embedded with a plurality of reinforcing structures connectable with a reinforcing cage or reinforcing mesh.

[0011] The technical principle of the present application is that prefabricated roof corner pieces, middle connecting pieces and end plate pieces are spliced, which can effectively improve the forming efficiency of the roof corner pieces, middle connecting pieces and end plate pieces, reduce the use of formwork, and reduce the cost of on-site construction. At the same time, the clamping structure can stably connect the roof corner pieces, middle connecting pieces and end plate pieces in sequence, so that the roof corner pieces, middle connecting pieces and end plate pieces have good waterproof properties. At the same time, the reinforcing structure can strengthen the strength and waterproof properties of the roof corner pieces, middle connecting pieces and end plate pieces.

[0012] At the same time, after the roof corner pieces, middle connecting pieces and end plate pieces are spliced, the reinforcing structure can be connected with the reinforcing cage or reinforcing mesh to prepare for the pouring of concrete. The entire structure can combine splicing and concrete pouring, improve the connection strength and waterproof performance of the roof corner pieces, middle connecting pieces and end plate pieces, and improve the construction efficiency of the roof concrete structure.

[0026] Further, the axes of the first steel bar and the second steel bar are parallel to the axes of the first clamping strip or the second clamping strip, and the steel bar structures are uniformly arranged along the roof corner piece, the middle connecting piece or the end plate piece.

[0055] In the installation and construction of the prefabricated building roof concrete waterproof component, the roof corner piece 1, the plurality of middle connecting pieces 2 and the end plate piece 3 are connected in sequence through the clamping mechanism.

The first cylindrical protrusion 411 and the first cylindrical groove 412 are both coaxially arranged with the first reinforcing bar 41.

[0064] After the first cylindrical protrusion is embedded into the first cylindrical groove 412 and the second cylindrical protrusion 421 is embedded into the second cylindrical groove 422, a clamp or other tool is used to pinch and deform the first cylindrical groove 412 of the first steel bar 41 and the second cylindrical groove 422 of the second steel bar 42, so that they are tightly fitted onto the first cylindrical protrusion 411 and the second cylindrical protrusion 421, thereby achieving tight locking connection of the adjacent first steel bar 41 and the adjacent second steel bar 42, making it easier to arrange a steel cage or a steel mesh at the end portions of the first steel bar 41, the end portions of the second steel bar 42 and the pouring engagement groove 5, and more easily improving the connection strength at the pouring engagement groove 5.
