Description

Technical Field

[0001] The present application relates to the field of building technology, and in particular to a prefabricated roofing component. Background Art

[0002] Roofing projects include multiple structural layers. During the construction process, each structural layer needs to be constructed separately layer by layer. Due to the large number of structural layers, the construction period is long and the quality is difficult to control. When the roofing project leaks due to hidden projects such as the later waterproof layer, or a certain structural layer cracks, expands and slips. It is often necessary to demolish and repair the structural layer. This will cause huge material waste and operational difficulties. Especially now that many types of buildings such as factories and public buildings are developing towards large-scale, the corresponding roofs are also becoming larger and larger, and the above roof construction problems are becoming more and more prominent. Therefore, it is urgent to provide a roof structure that is convenient for construction and repair. Utility Model Content

[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Figure 1 A schematic diagram of the structure of a prefabricated roof component provided in one embodiment of the present application. Figure 1As shown, the embodiment of the present application provides a prefabricated roof component, including a protective layer 1 and a thermal insulation layer 2 stacked along a first direction M, the thickness a of the protective layer 1 along the first direction M, and the thickness b of the thermal insulation layer 2 along the first direction M, satisfying a ≥ 2 / 3b. The above thickness ratio enables the prefabricated roof component to withstand wind loads when installing light equipment. The thickness a of the protective layer 1 ≥ 40 mm can ensure the crack resistance of the surface of the prefabricated roof component.

[0023] In the above embodiment, the prefabricated roof components realize the integrated prefabrication of the structural layer, can be assembled and laid on site, facilitate construction, and save building materials and labor costs. When maintenance is needed, the damaged prefabricated components can be dismantled and replaced without dismantling the entire structural layer, which saves costs and improves construction efficiency.

[0024] In one embodiment, the thermal insulation layer 2 may be a light and efficient thermal insulation material layer, such as an extruded polystyrene board layer. The protective layer 1 may be a concrete layer. The thermal insulation material layer with a thickness of not less than 2 / 3b of the concrete layer can ensure that the prefabricated roof components can resist floating by gravity when soaked. Therefore, the use of the above two material layers can ensure that the buoyancy of the prefabricated roof components after being soaked in water is not greater than their gravity.

[0025] When preparing the above-mentioned prefabricated roof components, first lay the thermal insulation layer 2 at the bottom, and then pour concrete on the thermal insulation layer 2 by integral pouring and bonding, so as to integrate the thermal insulation layer 2 and the protective layer 1 to form the prefabricated roof components.

[0026] In one embodiment, the above-mentioned concrete layer can be prepared by C20 grade concrete. This strength grade is 20MPa, which is medium-strength concrete and is generally suitable for preparing some smaller structural parts. And its fluidity is good, and it can fill the gaps in the mold well during pouring. And its durability is good, and it can maintain the stability of the structure for a long time. In addition, C20 concrete has good frost resistance and can be used in cold areas. The above-mentioned extruded polystyrene board is a polystyrene resin supplemented with a polymer during heating and mixing, and a catalyst is injected at the same time, and then extruded to form a continuous closed-cell foamed rigid foam plastic board. It has an independent closed bubble structure inside, and is an environmentally friendly thermal insulation material with excellent properties such as high pressure resistance, low water absorption, moisture-proof, airtight, light weight, corrosion resistance, anti-aging, and low thermal conductivity. Extruded polystyrene board solves the problems of material leakage, penetration, frost, condensation, etc. It also has the characteristics of high thermal resistance, low linearity and low expansion ratio. The molecular structure itself does not absorb water and has no gaps, which solves the problems of material leakage, penetration, frost and condensation. The special structure makes it light and high-strength, easy to cut, transport and install. It is suitable for dry wall insulation, flat concrete roof and steel structure roof insulation, low-temperature storage cold storage insulation, etc.

[0027] When the above-mentioned prefabricated roof components are specifically prepared, their size can be 1m×1m×150mm. Among them, the thickness of the protective layer 1 can be 60mm, and the thickness of the thermal insulation layer 2 can be 90mm. The use of this size can make the prefabricated roof components convenient for transportation, on-site paving, and later maintenance and disassembly. In addition, the use of prefabricated roof components of this size reduces the situation of floating in water.

[0028] Figure 2 A schematic diagram of the structure of a prefabricated roof component provided in another embodiment of the present application. Figure 2 As shown, in one embodiment, the above-mentioned prefabricated roofing component may further include a reinforcing rib 3, which is buried in the protective layer 1. The above-mentioned reinforcing rib 3 may be a steel bar. The steel bar has good plasticity and toughness, and can withstand large deformation without damage. At the same time, it also has high strength and tensile strength, and can withstand large tensile force without breaking. In addition, the steel bar also has good corrosion resistance and can resist the influence of various harsh environments. The reinforcing rib 3 is arranged in the protective layer 1 to improve the strength and durability of the protective layer 1.

[0029] In one embodiment, the reinforcing ribs 3 in the protective layer 1 may be a mesh structure. Specifically, the reinforcing ribs 3 include a plurality of first reinforcing ribs 31 spaced apart along the second direction N and a plurality of second reinforcing ribs 32 spaced apart along the third direction Q. The first direction M, the second direction N, and the third direction Q are perpendicular to each other, so that the first reinforcing ribs 31 and the second reinforcing ribs 32 form a mesh structure. The first reinforcing ribs 31 and the second reinforcing ribs 32 may be connected by binding and overlapping. After connection, concrete is poured so that the reinforcing ribs 3 and the protective layer 1 are integrated.

[0030] It is worth noting that, in other embodiments, the second direction N and the third direction Q may not be perpendicular.

[0031] In another embodiment, there may be a gap between the first reinforcing rib 31 and the second reinforcing rib 32 along the first direction M.

[0032] In a specific embodiment, the cross section of the reinforcing rib 3 is circular, and the diameter of the reinforcing rib 3 is 6 mm, so that the strength of the protective layer 1 is relatively high.

[0033] In one embodiment, the above-mentioned prefabricated roof component further includes a connector 4, which is made of metal. The connector 4 is connected to the reinforcing rib 3 and extends in a first direction away from the thermal insulation layer 2. The connector 4 is used to connect to a steel bracket. The above-mentioned steel bracket can be, for example, a fixed metal steel frame structure of a light equipment connected to the prefabricated roof component.

[0034] The above-mentioned light equipment can be a solar panel, which has a steel bracket. After the prefabricated roof components are laid, the solar panel is laid on the outer layer of the prefabricated roof components. The solar panel can be connected to the connecting piece 4 of the prefabricated roof components by welding.

[0035] In one embodiment, the connecting member 4 may be specifically connected to the first reinforcing rib 31 , or the connecting member 4 may be specifically connected to the second reinforcing rib 32 .

[0036] Figure 3 A schematic diagram of the structure of the first reinforcing rib, the second reinforcing rib and the connecting member provided in one embodiment of the present application. Figure 3 As shown, in another embodiment, the connection between the first reinforcing rib 31 and the second reinforcing rib 32 forms a node, and one end of the connecting member 4 can be fixedly connected to the node. When preparing the protective layer 1, the pre-connected first reinforcing rib 31, the second reinforcing rib 32 and the connecting member 4 can be laid, and then concrete can be poured to form an integrated structure. The other end of the connecting member 4 extends out of the surface of the protective layer 1.

[0037] In a specific embodiment, the number of the above-mentioned connecting members 4 is four. Of course, it can also be other numbers, such as six, two, eight, etc., which can be set according to the installation requirements of the light equipment, and this application does not make specific restrictions.

[0038] On the other hand, an embodiment of the present application further provides a roof structure, which includes a plurality of prefabricated roof components in any of the above embodiments. The plurality of prefabricated roof components are closely arranged and laid on the roof along the second direction and the third direction, and the thermal insulation layer is attached to the roof. The above roof can be a positive roof or an inverted roof. The roof structure is convenient for laying and construction, and is easy to replace after a prefabricated roof component is damaged, saving building material costs and improving construction efficiency.

[0039] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of this application and their equivalents, the present invention is also intended to include these modifications and variations.
