Description

Technical Field

[0001] This utility model relates to the field of pitched roof technology, specifically a composite sloping roof. Background Technology

[0002] With the rapid development of my country's construction industry and the increasing awareness of green energy conservation and environmental protection, the modernization of the construction industry has developed rapidly. Among them, the composite wall panel shear wall system has also made great progress. The roof is the surface of the building's roof, located between the ridge and the eaves, occupying a large area of ​​the roof. It is not only a roof covering, but also undertakes multiple functions. The composite panel is a prefabricated building formwork system, which is composed of precast panels and cast-in-place reinforced concrete layers.

[0003] A search revealed Chinese patent CN203296273U, which discloses a tiled pitched roof. Addressing the issue of insufficient drainage after construction of each layer of the tiled pitched roof, leading to water blockage and accumulation in multiple areas, resulting in severe leaks, the patent proposes a solution. This involves applying a 10-15mm thick polyurethane coating to the roof panels, followed by a modified bitumen waterproof membrane, then a 30mm thick expanded perlite insulation board. Wooden joists, each 30mm high, are installed every 0.8-1.2m along the expanded perlite insulation board. A mortar bonding layer is then applied to the expanded perlite insulation board, and finally, asphalt shingles are laid on top of the mortar bonding layer. This method is relatively simple and practical.

[0004] While the aforementioned pitched roof facilitates drainage, it presents significant construction challenges. Traditional pitched roof construction typically relies on cast-in-place processes, which involve multiple steps. First, formwork is installed to create the foundation framework for subsequent construction. Next, reinforcing steel is tied to enhance structural strength. Then, concrete is poured to shape the roof. Finally, surface finishing is performed to ensure the roof's flatness. However, this traditional method has significant drawbacks. Due to the unique shape of pitched roofs, on-site formwork is extremely difficult, consuming substantial manpower, resources, and time. Furthermore, inaccurate formwork can easily affect the roof's quality. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a composite sloping roof.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a composite slab pitched roof, comprising multiple bottom templates, a trapezoidal butt joint protrusion II fixed on one side of the bottom template, a trapezoidal butt joint groove II on the other side surface of the bottom template, the trapezoidal butt joint groove II being adapted to the trapezoidal butt joint protrusion II, a side template I on one side of one bottom template, a side template II on one side of another bottom template, the side template II being disposed on one side of the side template I, and an upper template at the upper end of the bottom template.

[0007] As a further description of the above technical solution:

[0008] One side of the side template is provided with a trapezoidal docking groove, and there are two trapezoidal docking grooves. The trapezoidal docking grooves are adapted to the trapezoidal docking protrusions.

[0009] As a further description of the above technical solution:

[0010] One side of the second side template is provided with a trapezoidal butt joint protrusion, and there are two such protrusions. The trapezoidal butt joint protrusions are adapted to the trapezoidal butt joint groove.

[0011] As a further description of the above technical solution:

[0012] Both the first and second side templates have longitudinal slots on their surfaces, and the bottom template has transverse slots on its surface.

[0013] As a further description of the above technical solution:

[0014] The interior of the horizontal and vertical slots is provided with bottom baffles, and the surfaces of the upper and lower templates are provided with insertion holes.

[0015] As a further description of the above technical solution:

[0016] The number of sockets is multiple, and each socket has a plug rod inserted inside.

[0017] As a further description of the above technical solution:

[0018] Multiple insertion rods are arranged on one side of the bottom baffle, and side template one and side template two are respectively arranged on both sides of the upper template.

[0019] This utility model has the following beneficial effects:

[0020] Compared to traditional cast-in-place pitched roofs, composite slab pitched roofs combine prefabrication with on-site assembly, eliminating the need for complex and difficult on-site formwork. This significantly saves construction time and labor costs. Furthermore, the prefabrication of composite slabs in the factory ensures higher dimensional accuracy and quality stability, effectively improving the overall quality of the pitched roof. This results in a flatter roof, a more stable structure, reduces the difficulties of on-site formwork, minimizes waste of human resources, and reduces problems such as uneven overall flatness and structural strength caused by minor deviations in the formwork process.
