Description
Technical Field
The invention relates to the technical field of building products, in particular to a roof component integrating roof tiles and roof heat preservation, a manufacturing method and an installation method.
Background
Tiles and their constructed sloping roofs are the most typical features of traditional buildings. "Qin brick Han tile" is the main mode of traditional building products in our country. By means of the sintered bricks and tiles with different shapes, Chinese nationality creates a unique architectural style. The slope roof has rain-proof and water-proof effects and has certain heat preservation and heat insulation effects. According to the size of rainwater and snow, the purpose of preventing water and snow accumulation load is achieved by changing the gradient. Along with the development of the economic society of China, high-rise buildings and mansions stand; however, the slope roof building with the traditional characteristics is increasingly favored by wide villages and towns mainly based on low-rise buildings. The traditional special slope roof building can show the special features and the appearances of new rural areas and also hold a worries.
However, the traditional sintered tile takes clay as a resource, which is unfavorable for land protection; the traditional firing process also has no economic feasibility of large-area popularization. Therefore, the modern materials and the process are adopted to prepare the traditional special roof tile. The cement-based tile product has excellent durability, and can show the shape and fine patterns of the traditional sintered tile through mould forming. Therefore, the traditional special roof tile manufactured based on the cement-based material can meet the functional requirements of the building envelope, can also show the style of the traditional building, and has the feasibility of popularization.
The roof of the traditional building is made of plants (such as reed foils, rice straws, wheat straws and the like) and soil, and the like, and the traditional roof heat insulation method cannot meet the energy-saving requirement of the modern building due to the large heat conductivity coefficient and the limitation of the thickness of the roof (the limitation of bearing in essence). For sloping roof buildings, the building form factor is large, and the requirement on building heat insulation is higher. Therefore, the sloping roof needs to select more efficient heat insulation materials to meet the requirements of energy-saving standards for urban and rural construction.
The slope roof system of the traditional building has the disadvantages of complex structure, high construction difficulty, high skill requirement on craftsmen, high manufacturing cost, and popularization obstacles in various aspects such as technology, economy, human resources and the like. The assembly type based on the industrialized idea is more and more emphasized in China. The products or parts with integrated functions prepared in factories reduce the artificial deviation of site construction and reduce the labor intensity. The limitation of manual carrying weight is received, the specification and size of products such as bricks and tiles of the traditional building are small, the great manpower is consumed during construction, and the construction quality problem is easily caused by more construction nodes. The integrated product can realize the manufacture of large-size products on the premise of keeping the characteristics of the traditional products. The assembled product is prefabricated in factories, can be finely designed and accurately manufactured, and is convenient for quality control.
Based on the idea of assembly type building, the modern building material manufacturing technology and the house building method are adopted to show the appearance of the traditional building sloping roof, and a plurality of difficulties also exist. First, traditional buildings are usually curved pitched roofs, rather than flat pitched roofs; not only the curve outline of the building is reflected, but also excessive anisotropic components which are not suitable for large-scale manufacturing are avoided; secondly, the roof construction is inconvenient for installing operation supports (such as scaffolds and the like) penetrating through the roof, so that the product can be safely constructed under the condition; and thirdly, the roof is of a capping structure, the supporting and transporting conditions of construction operation are limited, and the operation protection is also limited.
The main structure of the sloping roof system comprises a main structure, a waterproof structure, a heat-insulating structure and roof tiles. The main structure bears the stress of the whole roof system, mainly adopts a concrete roof panel and steel (wood) structure form, and adopts a brick-wood structure or a wood structure in the traditional building. The roof tiles of pitched roofs assume the role of water diversion and waterproofing, which is usually achieved by means of the slope, the waterproofing of the roof tiles, and the overlap between the tiles. The construction of the traditional sloping roof is carried out in sequence according to the structural layers from bottom to top.

The invention is described in further detail below with reference to the attached drawing figures:
as shown in fig. 1 to 3, the present invention provides a roofing tile and roofing heat-insulating integrated roofing component, which comprises, from top to bottom: the roof tile 3, the polyurethane layer 4, the double-sided steel wire net rack plate 2 and the cement polyphenyl granule layer 1; wherein:
the double-sided steel wire mesh frame plate 2 comprises a steel wire mesh frame and an insulation plate 6 arranged in the middle of the steel wire mesh frame, the steel wire mesh frame on one side of the insulation plate 6 is embedded into the polyurethane layer 4, and the steel wire mesh frame on the other side of the insulation plate 6 is embedded into the cement polyphenyl granule layer 1.
The lower side of the roof component and the roof tile 3 on the left side are provided with first connecting parts, and the upper side of the roof component and the roof tile 3 on the right side are provided with second connecting parts lapped with the first connecting parts. Further, the first connecting portion of the present invention may be a concave portion 7, and the second connecting portion may be a convex portion 8. As shown in fig. 2 and 3, when the roof tiles 3 are overlapped up and down, the lower roof tile 3 of the first roof member a is provided with a stepped recess 7, i.e., the outermost step is higher than the inner step; the upper roof tile 3 of the second roof component B is provided with a step-like bulge 8, i.e. the outermost step is higher than the inner step; the lapping of the upper and lower roof members can be realized through the matching of the two stepped concave parts 7 and the convex parts 8; and the stepped concave part 7 and the convex part 8 also have a limiting function. As shown in fig. 4 and 5, when left and right overlapping is performed, the lower concave button (concave part 7) of the left roof tile 3 of the first roof component B is just required to be arranged at the upper convex part (convex part 8) of the right roof tile 3 of the second roof component B, and the left and right overlapping mode is completely consistent with the construction mode of the traditional roof tile.
The design principle of the roof component integrating the roof tile and the roof heat insulation is as follows:
1. the load bearing capacity includes dead load, wind load, snow load, accidental earthquake load, etc. In the case of roofing systems, the load bearing thereof is borne by the main structure, and is accomplished by structural design. The design should be able to be performed by the subject structure designer in accordance with the relevant design specifications.
Roofing tile and roofing heat preservation integrated roofing component, its performance mainly is: (1) the roof member has the lowest compression strength (bearing self load, snow load, people getting on and the like), and the heat insulation plate arranged in the double-sided steel wire net rack plate is arranged in the weakest level of the compression strength of the roof member. The cast-in-place rigid foam polyurethane layer and the cement polyphenyl granule layer both have higher compressive strength and are also roof heat-insulating materials recommended in design specifications such as roof engineering technical specification GB 50345 and commonly used in engineering. Arrange the heated board in two-sided steel wire net rack board, owing to by the supporting role of wire net rack, greatly increased the compressive strength of component and the optional scope of heated board. (2) Bending strength, the rigid roof tile and the steel wire net frame greatly improve the bending resistance of the roof member. (3) Tensile strength perpendicular to the surface, which is primarily resistant to wind loading of the roof element; the tensile strength of the roof member vertical to the surface is not lower than 0.10MPa, so that the roof member can meet the wind pressure resistance requirement of buildings with the height of more than 100 meters under the condition of different ground roughness.
2. Thermal insulation performance. Taking the current 75% energy-saving standard in Beijing city belonging to cold regions as an example, the heat transfer coefficient of the roof is required to be not more than 0.30W/(m) for the buildings with three or less layers2K). Namely, the requirement on the heat preservation of the pitched roof building is higher than that of a medium-high building. Consequently, insulation designs for roofing systems are more difficult, and insulation layers of less than 200mm are generally acceptable. Thus, an efficient heat-insulating material is needed, and the heat conductivity coefficient of the cast-in-place foaming polyurethane can reach 0.024W/(m)2K). The heat-insulating board placed in the double-sided steel wire mesh frame board can select different types of heat-insulating materials for buildings with low heat conductivity coefficients so as to meet the requirements of different heat transfer coefficients.
Because different areas have different building energy-saving standards, the heat transfer coefficient of the roof member can be adjusted in two ways, namely, the heat-insulating material type and the thickness of the heat-insulating material. The heat insulation of the roof member is composed of a cast-in-place foaming polyurethane layer, a heat insulation plate arranged in a steel wire mesh frame, a cement polyphenyl granule layer and the like. After testing the heat conductivity coefficient of each material layer, an engineer can calculate the thickness of each structural layer according to the civil construction thermal design specification GB 50176. As for the heat transfer coefficient correction coefficient required by the design, the heat transfer coefficient correction coefficient can be obtained according to the difference between the tested value and the calculated value of the heat transfer coefficient of one solid member, which is a method known by the engineer in the field.
3. And (4) waterproof performance. Roofing waterproofing is a difficult problem for roofing systems, even for sloping roofs. The invention solves the waterproof problem by the following technical measures.
(1) The roof tile has certain waterproof performance, and the performance of the roof tile meets the requirements of concrete tile JC/T746. (2) The cast-in-place foaming polyurethane and the roof tile form close chemical connection, and even if water seeps accidentally, the polyurethane layer also has a waterproof function. (3) The roof component and the roof component are in lap joint, so that the rainwater is smooth and prevented from being accumulated. (4) The connecting part of the roof member and the roof member adopts an expansion water stop belt (composed of expansion water stop materials) to prevent accidental water seepage.
4. And (4) fire resistance. The present invention provides a variety of material choices for construction that are needed for fire protection. (1) The indoor side of the member is provided with a cement polyphenyl granule layer which has A-level combustion performance and simultaneously gives the member light heat insulation property. (2) The heat-insulating board in the steel wire net rack board can adopt A-level combustion heat-insulating materials, such as rock wool boards, foam glass boards and the like. The cast-in-situ foaming polyurethane is a B1-grade flame-retardant material.
5. And constructing the connection of the layers. In fact, the connection of multiple layers of components is a difficult point in the design and implementation of the components. According to the invention, the double-sided steel wire net rack plate is connected with the roof tile through the cast-in-place foaming polyurethane, the reaction activity of the cast-in-place foaming polyurethane in the chemical reaction can be connected with the roof tile, and the connection enhancement effect of the back water surface of the roof tile can be further realized through the embedded steel wires 5. In a similar way, the cast-in-place foaming polyurethane layer is chemically connected with the steel wire mesh frame plate and the heat insulation plate in the steel wire mesh frame plate, and meanwhile, the double-sided steel wire mesh frame plate plays a role in further strengthening.
The cement polyphenyl granule layer is poured when the component is manufactured, the cement hydration reaction is chemically connected with the steel wire mesh frame plate and the heat insulation plate therein, and meanwhile, the double-sided steel wire mesh frame plate further achieves the reinforcing effect. When the interface of the cement polyphenyl granule layer is incompatible with the interface of the heat insulation plate, the interface agent can be used for processing. Those skilled in the art are aware of how to select an interfacial agent and a method for its implementation.
Furthermore, the back water surface of the roof tile 3 is provided with embedded steel wires 5.
The traditional roof tile is small in size, and a piece of sheet is lapped and fastened to form an integral roof, so that the functions of wind and rain shielding, heat insulation, decoration and the like are achieved. The traditional roof tile has strong decoration and forms different architectural styles in different regions of China. The basic points of prefabricated buildings are functional integration and structural productization. The roofing element of the invention has a transverse dimension of at least more than one metre, comprises a plurality of conventional tiles and also imparts to the roofing a decorative effect. One possible method is to make a mold, engrave the tile roof shape from a plurality of tiles on the mold, and then make a multi-tile combination product having the traditional roof tile shape thereon. The existing mold technology and engraving technology are mature, and a 3D engraving machine controlled by a computer is not difficult to find.
Roofing tiles come in a wide variety of materials, and cement-based materials are recommended because of their availability, low cost, and class a non-flammability. The cement-based tile can also be concrete tile, glass fiber reinforced cement and the like, and the index requirements of the tile can refer to concrete tile JC/T746, and can also refer to Japanese standard decorative cement tile for residential roofs JIS A5423. Synthetic resin tiles are also popular, class B1 fire rating, Standard "synthetic resin decorative tiles" JG/T346. The tile material should be selected to have good bonding performance with cast-in-place foamed polyurethane, and damage should occur in the polyurethane material during a tensile bonding strength test.
In order to increase the bonding force between the cast-in-situ foaming polyurethane and the roof tile, the back water surface of the roof tile is provided with embedded steel wires to form a mechanical bridging effect. In addition, the effect of enhancing the roughness of the back surface of the tile, the arrangement of uneven grids and the like can also be achieved.
Furthermore, the roof tile, the double-sided steel wire net rack plate and the heat-insulation plate are bonded through a polyurethane layer; the tensile bonding strength is not lower than 0.10MPa and the polyurethane layer is damaged; the polyurethane layer is a foaming polyurethane layer meeting the GB/T20219 requirement.
Polyurethane is a thermoset material that is generally formed by a chemical reaction that occurs when two components are mixed. This chemical reactivity in the chemical reaction can form good bonds with other materials. The invention utilizes the principle to connect the roof tile with the double-sided steel wire net rack plate (comprising the insulation board therein). Meanwhile, the hard foam polyurethane formed by foaming has certain compressive strength and good heat insulation performance. In the whole roof member, polyurethane is used as a light connecting layer, is a weak link of strength, and regulates the tensile bonding strength so as to ensure enough bonding strength. Tensile bond strength is tested by bonding the bond to the present bond and then stretching. When failure occurs in the polyurethane, it indicates that both the bonded object and the bonded interface have higher strength than the polyurethane. That is, when the "tensile bond strength is not less than 0.10MPa, and failure is in polyurethane", the tensile strength of the entire roofing member is not less than 0.10 MPa.
The raw materials of the rigid foaming polyurethane are mature commodities, and the proportion of tensile bonding strength not less than 0.10MPa can be obtained by the personnel in the industry under the guidance of material suppliers. Other requirements of polyurethane can be referred to the requirements of 'spraying rigid polyurethane foam' GB/T20219.
The tensile bond strength test method can be carried out by using the method of measuring the tensile bond strength of the heat insulating material, the binder and the base coating of the heat insulating product for buildings GB/T30803.

The double-sided steel wire mesh frame plate 2 is welded with the steel wire mesh sheets on two sides of the heat-insulating plate 6 by the abdominal wires penetrating the heat-insulating plate 6 to form a grid structure taking the heat-insulating plate 6 as a core material. The national standard GB26540 Steel wire mesh frame molded polystyrene board for external thermal insulation system of external wall makes technical regulation on a steel wire mesh frame board taking a molded polystyrene board as a core material. However, the standard is limited to molding polystyrene boards, and the core material of the invention can also conform to other insulation boards used for external insulation systems of thin-plastered building external walls, such as extruded sheets, polyurethane boards, phenolic resin boards, rock wool boards, foam glass boards and the like. The requirements for these insulation boards are known to those skilled in the art and are given in the relevant standards, such as "technical rules for exterior wall insulation engineering" JGJ 144 "," extruded polystyrene board (XPS) thin-plastered exterior wall insulation system material "GB/T30595", "rock wool thin-plastered exterior wall insulation system material" JG/T483, etc.
Further, the cement polyphenyl granule layer 1 is formed by mixing cement and polyphenyl granules, and the combustion performance grade is A grade; the cement polyphenyl granule layer 1 is a surface modified cement polyphenyl granule layer or a rubber powder cement polyphenyl granule layer.
The cement polyphenyl granule layer 1 is a material formed by bonding expanded polyphenyl granules by using cement as a main cementing material, and has light heat insulation property. The grade A combustion performance is to ensure the fire resistance. The material requirement of the layer can refer to 'glue powder polyphenyl particle external thermal insulation system material' JG/T158; china's combustion grade test executes the GB 8624 standard of ' grading combustion performance of building materials and products '.
