The roof panels are square or diamond or triangular or polygonal.

A reinforcing bar 102 is disposed on the inner side surface of the metal plate 101, and a recessed groove is formed between the adjacent reinforcing bar protrusions 102; the heat insulating layer 6 is provided with a protrusion corresponding to the recessed groove, and the protrusion is embedded in the recessed groove. As the outer metal plate 101, the edge 103 is set on the edge, and the vertical edge 103 covers the side of the heat insulating layer 6.

As an alternative preferred embodiment, the inside of the reinforcing bar 102 is a hollow body closed at both ends; the reinforcing protrusion 102 is provided with a plurality of through holes for the inflow of the slurry on the surface facing the metal plate 101 side, and The surface of the insulating layer 6 corresponding to the through hole extends from the through hole into the cavity of the reinforcing bar 102 to form a rod-shaped body of the corresponding structure.

When the outer layer 1 is composite cement or concrete, the outer layer 1 and the inner layer 2 are covered with a steel frame; When the outer layer 1 is a metal plate, the heat insulating layer 6 on both sides of the intermediate structure layer 3 is covered with a steel frame.

As shown in FIG. 2, the reinforcing bars 9 in the steel frame are cross-shaped, and at least one pair of reinforcing bar heads 4 respectively extend to opposite end faces of the outer layer 1, and welding is provided on the end face of the outer layer 1 at the position of the reinforcing bar head 4. The groove 5, the steel head 4 is at least partially exposed in the welding groove 5; when the wall is built, the opposite welding grooves 5 of the adjacent roof panels are aligned, so that the steel head 4 in the groove can be welded together; when the inner layer 2 and the outer layer 1 When the steel frame is laid, the steel bars in the inner and outer layers have the same shape and position, and the reinforcing bars 8 are arranged to connect the two steel bars together; the two steel bars 9 corresponding to the positions in the two layers, and one reinforcing bar 8 The connection forms a U-shaped frame closed at one end, and the connection position of the reinforcing rib 8 and the reinforcing bar 9 is in the welding groove 5.

When the outer layer 1 is composite cement or concrete, the outer layer 1 and the inner layer 2 are covered with a steel frame; the end surface of the roof panel is provided with a welding groove 5, and the steel bar 4 of the steel frame is at least partially exposed in the welding groove 5, the steel bar A pin hole is provided in the head 4.

As shown in Fig. 13, the roof panels are stacked between the roof panels and welded by the steel heads 4; the roof panels and the columns and beams can also be provided with corresponding welding points, and the steel heads 4 are welded to the roof panels.

As shown in FIG. 1 and FIG. 3, on the end faces of the outer layer 1 and the inner layer 2 composed of a concrete layer or a composite cement layer, concave and convex bodies connected to adjacent roof panels are provided, and the concave and convex bodies are concaves which are configured to be coupled to each other. The groove 7 and the protrusion; the groove 7 and the protrusion have a triangular or curved or square cross section.

As shown in FIG. 4, FIG. 5, FIG. 6, and FIG. 8, when the outer layer 1 is composite cement or concrete, a plurality of bolt holes 32 are provided in the intermediate structure layer 3, and the bolt 31 is disposed in the bolt hole 32. Both ends of the bolt 31 penetrate into the heat insulating layer 6 on both sides. When the intermediate structure layer 3 is set to two layers, the pin holes 32 on the two intermediate structure layers 3 are alternately arranged as shown in FIG.

For the bolt, the strength determines the strength of the roof panel; the bolt diameter is larger, the metal material is used, and the cost is higher; the non-metal material is used, and the strength is small. Therefore, to further improve For the strength between the layers, a preferred alternative is that, as shown in FIG. 7, the bolt 31 has a cavity 311 of the cavity, the two ends of the rod 311 are cavity ends; the middle of the rod 311 is provided with an inlet 312, and two cavity ends The head is provided with a discharge port 315. In the cavity structure, when grouting, the slurry enters the cavity of the bolt to form a complete rod-shaped rod, and the rod-shaped rod which is hardened by the slurry can provide higher strength than the bolt, and the cost is lower.

During the grouting, since the rod body 311 is transversely disposed, the gas in the cavity is not easily discharged, and a large amount of gas is easily stored, so that the rod-shaped rod formed in the cavity of the rod body is likely to have a large number of pores, thereby affecting the strength of the rod body. Therefore, a spring 31 and two sliders 313 are disposed in the cavity of the rod body 311; the slider 313 is disposed on both sides of the inlet 312 and is in sliding engagement with the cavity of the rod body 311; the spring 314 is abutting at both ends a tension spring on the slider 313, or a compression spring having one end abutting on the slider 313 and the other end abutting on the cavity end of the side; the slider 313 is provided with a plurality of through holes extending through the two ends; The total effective sectional area of the via holes on the slider 313 is smaller than the effective sectional area of the inlet 312, which is larger than the effective sectional area of the side discharge port 315. When the bolt 31 is placed in the intermediate structure layer, the two ends are disposed on both sides of the intermediate structure layer and arranged symmetrically; at this time, the inlet 312 is symmetrically disposed with respect to the intermediate structure layer, and the areas on both sides of the intermediate structure layer are equal. The slider 313 is divided on both sides of the inlet 312, and the space between the two sliders is much smaller than the space outside the slider, that is, the amount of air between the two sliders is smaller than the amount of air at both ends of the two sliders. To facilitate the discharge of air, a plurality of via holes are provided on the outer circumference of each slider 313 or adjacent to the outer circumference.

When the filled slurry is at a height to the rod body, it enters the cavity through the inlet 312 and the discharge port 315 on the rod body; since the effective cross-sectional area of the inlet 312 is large, the slurry entering from the inlet 312 is more and enters faster. . When the slurry first enters between the two sliders through the inlet 312, the force of the spring causes the slider to not slide, and the accumulation height of the slurry between the sliders gradually rises, and while the space of the two sliders is compressed, the space of the two sliders is compressed. The air is squeezed between the blocks, and the extruded air is partially discharged from the inlet, and partially discharged from the through holes in the slider to the cavity at both ends of the two sliders until the slurry rises to fill The space between the two sliders. When the space between the sliders is filled, the external slurry is communicated through the slurry between the inlet and the slider. At this time, the pressure of the external slurry is transmitted to the slurry between the sliders through the inlet, and the slurry between the sliders themselves The pressure plus the pressure of the external slurry can overcome the force of the spring, moving the two sliders to the ends, forming a larger space, correspondingly introducing more slurry and extending the length of the rod. The slurry between the two sliders forms a rod-shaped rod, and since the air is evacuated sufficiently, the pores on the rod-shaped rod are small, thereby improving the tightness of the rod-shaped rod and improving the strength. The total effective sectional area of the via hole on each of the sliders 313 is smaller than the effective sectional area of the inlet 312, which is larger than the effective sectional area of the side discharge port 315. This structure makes the slurry velocity flowing between the sliders larger than the discharge port 315. The speed of entry, plus the space between the sliders, is smaller than the space between the two sliders. Therefore, when the slurry fills the space between the sliders, the slurry at both ends of the two sliders is still less and the accumulated slurry The height is still low, so that the two sliders leave a large space to move to both ends, that is, the bar-shaped rod formed by the slurry between the sliders can have a large length to bear the load. In addition, the two ends of the slider are subjected to a spring force structure, so that the rod-shaped rod is also symmetrically arranged with respect to the intermediate structure layer.

As shown in FIG. 14, a connecting rod 52 is disposed between the two panel layers 1; when the connecting rod 52 is a heat conductive material, the connecting rod 52 is directly connected to the two panel layers 1; when the connecting rod 52 is a heat insulating material, two A connecting plate 51 is disposed between the panel layers 1. A connecting rod member 52 is disposed on both sides of the connecting plate 51, and at least one connecting rod member 6 is disposed on each side. One end of the connecting rod member (6) is fixed on the connecting plate 51, and the other end is fixed. It is fixed on the panel layer 1 on the corresponding side.

As shown in FIG. 14, FIG. 15, and FIG. 16, a connecting rod member 52 is disposed on one side of the connecting plate 51, and two connecting rod members 52 are disposed on the other side, or two connecting rod members 52 are disposed on both sides; When one connecting rod member 52 is disposed on one side and two connecting rod members 52 are disposed on the other side, the single-side connecting rod member 52 is disposed between the two connecting rod members 52 on the two sides; when the connecting plate 51 is on both sides Two connecting rod members 52 are provided, and the connecting portions of the four connecting rod members 52 and the connecting plate 51 are distributed at four corners, and the same side connecting rod members 52 are located at diagonal positions.

When the steel frame is provided in the two panel layers 1, the connecting rod 52 can be connected to the steel frame.

Embodiment 2: The manufacturing method of the invention for manufacturing a new energy-efficient building roof panel, as shown in FIG. 10, FIG. 11, and FIG. 12, the two ends of the bolt 31 are symmetrically placed on the intermediate structure layer 3. In the bolt hole 32, one or two intermediate structure layers 3 are placed between the two templates 11; when the intermediate structure layer 3 is two layers, a space is provided between the intermediate structure layers 3, and the pre-mixed foamed cement is used. The thermal insulation material slurry is poured into the gap between the two template 11 and the two intermediate structural layers 3 and between the two intermediate structural layers 3; when the intermediate structural layer 3 is a layer, the premixed foamed cement thermal insulation material slurry is prepared. The material is poured into the gap between the two templates 11 and the intermediate structure layer 3, or the outer layer 1 and the inner layer 2 are disposed inside the two templates 11, and the premixed foamed cement insulation slurry is poured into the outer layer. 1. The inner space between the inner layer 2 and the intermediate structure layer 3; the inner side surface of the template 11 corresponding to the outer surface of the outer layer is a planar structure or a curved surface structure or a tile-like surface structure.

When the intermediate structural layer 3 is two layers, the bolts 11 on the two intermediate structural layers 3 are positioned offset.

After the slurry is poured into the gap, the foaming curing is carried out; when the foamed cement insulation material can be cut, the foamed cement insulation material outside the overflow edge is cut off.

The different requirements of the inclined roof and the flat roof and the strength of different materials are determined.

Technical measures and technical features of the roofing panel product of the invention

1. When the metal plate is used as the outer structural layer or inner structural layer of the roof panel product:

1 The metal plate is arranged with an appropriate amount of latitude and longitude arrangement of steel bars on the inner surface. The steel bars are connected and fixed by spot welding. The reinforcing bars have three functions: a. Strengthening the strength of the metal plates and reducing the thickness of the metal plates as appropriate; b. In the case where the outer structural layer or the inner structural layer is provided with reinforcing bars, it is convenient to use a plurality of short reinforcing bars to connect with the opposite inner structural layer or the outer structural layer to form a supporting and fixing, so that the outer and inner structural layers are insulated in the middle. The structural layer of the material is firmly integrated into one body; c. the warp and weft-shaped reinforcing steel protruding on the inner surface of the metal plate, the cylinder thereof The concave and convex space generated by the shape itself is convenient for foaming and solidifying the foamed cement thermal insulation material slurry which is cast into the outer layer, and the thermal insulation layer in the middle of the inner structural layer is grasped.

2 The edge of the metal plate as the outer structural layer of the roof panel shall have pre-compressed interlocking edges (the rainwater may be prevented from entering after the bite is installed), and other connection waterproofing measures may also be adopted.

2. When concrete or composite cement is used as the outer structural layer or inner structural layer of the roof panel:

1 In the case of not affecting the strength, the construction waste (mainly the removed waste concrete block) is rolled into granules instead of the concrete used for the concrete; a certain proportion of the production of foamed cement insulation material is added to the composite cement layer. Corner scrap particles or other inorganic light-collecting materials to reduce the weight of the roof panel itself.

2 In the precast concrete layer or composite cement layer, add appropriate amount of alkali-resistant high-strength engineering fiber and a little pepper, pepper, etc. to increase the strength of cracking and deworming.

3 Pre-embed the weft-arranged steel mesh (also in other arrangements) in the concrete layer or the composite cement layer, and use some short steel bars between the outer structural layer and the two pre-embedded steel meshes in the inner structural layer. The two layers of steel mesh are welded to form a support and fixed; at the same time, the four connecting end faces of the outer structural layer and the inner structural layer (refer to the interface with the other layer panels) and the embedded reinforcing bars of the contact faces of the inner structural layer facing the lower surface and the beam are exposed. At the end, the location of the slots required for soldering or other attachment methods should be reserved for the installation of the roof panel and the roof panel, the panel between the deck and the beam or other attachment methods.

The four connecting end faces of the outer structural layer and the structural layer have a prefabricated concave-convex structure, so that the interfacial prefabricated roof panel and the roof panel are bonded to the concave and convex structural surface by a special bonding mortar, and the intermediate insulating material layer is further It is well sealed and closed; after the installation of each house roof panel is completed. If the end surface of the four peripheral edges of the roof is exposed, the relevant special mortar should be wiped to cover the exposed end surface of the intermediate insulation material.

3. Technical characteristics of structural layers of thermal insulation materials

1 two types of insulation materials combination

The heat insulation function and the roof panel are integrated into one, so that it becomes a heat-insulating roof, and at the same time, because the heat insulating material is sealed between the outer and inner structural layers, the durability of the organic heat insulating material is greatly improved, and the organic type is eliminated. Insulation materials for fire hazards related to external thermal insulation have played a role in fire prevention. The organic insulation material is combined with the inorganic insulation material.

The thermal insulation material is used as the intermediate structural layer of the roof panel. Through this construction method, the thermal insulation function and the roof are integrated to make it a thermal insulation roof, and at the same time, because the thermal insulation material is sealed between the outer and inner structural layers, the The use of organic insulation materials for fire hazards related to external insulation has played a role in fire prevention. At the time of production, the material can be constructed according to the energy saving requirements of the building.

1 The cold zone is short in winter and long in summer (the frost period is longer than the frost-free period). The main problem is to solve the problem of building insulation. In winter, the structural layer inside the roof of the house is in the warm state of the house, while the structural layer outside the roof is in the low temperature for a long time. In the low temperature up to several tens of degrees below zero, the adverse effect of the buffer temperature difference on the structural layer of the intermediate thermal insulation material (such as condensation) and the guarantee of energy saving effect, A, as a preferred suggestion, the structural layer of the intermediate thermal insulation material is made of inorganic materials such as foamed cement. The material is combined with an organic type such as an extruded polystyrene board by a method in which a piece of extruded polystyrene board having the same size as the outer and inner structural layers is placed in the space between the outer structural house and the inner structural layer. (the squeeze There are several bolts on the surface of the plastic polystyrene board. The two ends of the bolts are exposed on the outer surface of both sides of the extruded polystyrene board, which is mainly used to grasp the layer of foamed cement insulation material. . The material of the bolt can be metal or wood, bamboo, etc., and it is recommended to make high-strength carbon fiber. Then, the pre-mixed slurry of cement insulation material is poured into the outer structural layer, the inner structural layer and the extruded polyphenylene. In the gap between the plates, foaming and blooming maintenance shall be carried out. When the foamed cement insulation material can be cut, the foamed cement insulation material which overflows the edge of the roof panel (the edge between the outer and inner structural layers) is removed. can. B. Another type is to first put a plurality of bolts on the extruded polystyrene board, and the big ends (or elbows) at both ends of the bolts are exposed to the surface of the extruded polystyrene board, and then the extruded polyphenylbenzene is fixed with the bolts. The board is placed in the touch tool, and the mixed composite cement is directly cast into the space between the mold and the extruded polystyrene board to be cured.

2 The hot summer and warm winter in the tropical region is mainly to solve the problem of heat insulation of the building. The structural layer inside the house panel is relatively cool in the house, and the structural house outside the roof is often in the relatively high temperature of tens of degrees above zero ( The direct sunlight of the house will be much higher than the daily air temperature. It is recommended to construct the structural layer of the intermediate insulation material of the roof panel with reference to the cold zone.

3 In the temperate zone, it is recommended to use only one type of insulation material such as foamed cement insulation material as the intermediate structural layer (made by casting method).
