The rockwool sandwich board roof panel
Technical field
The utility model relates to a kind of plywood sheet structure.
Background technology
Common sandwiched plate roof board material is selected the incendive materials of appearance such as extruded sheet, although heat insulation effect is better, just in case the building breaking out of fire of using will cause great loss.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned the deficiencies in the prior art, and good, the easy for installation rockwool sandwich board roof panel of a kind of good sealing effect, fireproof performance of exploitation.
The technical solution adopted in the utility model is as follows:
A kind of rockwool sandwich board roof panel, it is characterized in that it includes the rock wool central layer, the two sides of described rock wool central layer are provided with metal sheet, one end of metal sheet is provided with the connection strap stretched out, two roof panel that face the mutually wherein connection strap of cover the end of another piece, and be joined with bolts, be provided with sealant layer in the connection gap of two roof panel.
The end of described bolt is equipped with attachment cap.
The beneficial effects of the utility model have:
Simple and practical, there is the characteristics such as insulation, heat insulation, sound insulation, fire prevention, waterproof, lightweight, being assembled into industrial premises, exhibition hall's trading hall, sports palace, freezer, warehouse and activity with it is the desirable bodies of wall of getting twice the result with half the effort in the modern times by all kinds of buildings such as rooms.It has once and completes, the characteristics such as speed of application is fast, durable in use, elegant in appearance.Maximum characteristics sheet material adopts this fire-retardant material of rock wool, except possessing good heat-insulating property, also has superpower fire retardant performance.

End construction schematic diagram when Fig. 1 is two roof panel connection of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, it includes rock wool central layer 1 the utility model, and the two sides of described rock wool central layer 1 are provided with metal sheet 2, and metal sheet 2 can adopt zinc-plated color steel sheet, and thickness is 0.4-0.8mm.Also can adopt aluminum-zinc alloy color steel sheet or aludip.Steel plate is first compound with the rock wool compounding machine again after the forming machine roll forming.Rock wool central layer 1 adopts density to be that the 120kg/m3 mineral wool block is staggered and lays, and its fiber orientation is perpendicular to the upper and lower surface of sandwiched plate, and close proximity has been enriched the whole cross section in length and breadth of sandwiched plate.Pass through the bonding integral body that forms of high strength blowing agent between rock wool central layer 1 and between rock wool central layer 1 and upper and lower layer metal sheet 2, superior production technology has guaranteed can produce extremely strong adhesion strength between highdensity rock wool insulator and metal sheet inwall, thereby makes rockwool sandwich board have good rigidity.
One end of described metal sheet 2 is provided with the connection strap 3 stretched out, two roof panel that face the mutually wherein connection strap 3 of cover the end of arriving another piece, and be connected and fixed with bolt 4, be provided with sealant layer 6 in the connection gap of two roof panel, guarantee the sealing that two roof panel connect, strengthen bonding strength simultaneously.The end of bolt 4 is equipped with attachment cap 5, improves the connection effect of bolt 4.
When mounted, the end by the connection strap of a roof panel 3 lids to another piece roof panel, bolt 4 is put on attachment cap 5 two roof panel is connected and fixed, can realize the splicing of two roof panel, by that analogy, can realize the splicing of polylith roof panel, installation rate is than very fast.After roof panel is installed to building wall, can realize good heat insulation effect.
Other undeclared part that the utility model relates to is same as the prior art.
