Description

Roof sandwich panel system

Technical Field

The invention relates to the field of roofs, in particular to a roof sandwich panel system.

Background

Metal roofing sandwich panels are also becoming more and more widely used in civil, public and industrial buildings. Particularly, the assembly type building is widely popularized and applied in China, and has shown a rapid growth trend; the metal surface sandwich board for the building roof is an indispensable part finished product of the assembly type building. At present, as shown in fig. 1 to 4, a metal roof sandwich panel generally comprises three parts, namely an outer plate 11, a core material 12 and an inner plate 13. The inner plate 13 and the outer plate 12 are generally made of 0.5-0.8 mm thin color galvanized steel plates, aluminum plates or stainless steel plates which are rolled into various plate types by a machine; the core material 12 is various, and at present, rock wool, glass wool, polyurethane, phenolic resin, foam glass and the like are mainly used. The three are bonded together under the action of certain temperature and pressure through proper interface adhesive to form the metal surface sandwich board with metal plates on two sides and heat insulating material in the middle.

As shown in fig. 3 and 4, it can be seen that the sub-openings 15 and the main openings 14 of the left and right metal roof sandwich panels are designed into a certain shape, and then the left and right metal roof sandwich panels can be connected with a roof support structure 17, i.e. a roof purlin support, through connecting nails, i.e. self-tapping screws 16, by a certain installation sequence. The installation sequence of the metal roof sandwich panel in the prior art is as follows: 1. firstly, mounting a roof purline, namely a roof purline support piece, on a steel frame beam; 2. secondly, mounting a first metal roof sandwich plate in place at the design position of the roof purline; 3. then, installing self-tapping screws at the seam allowance of the first metal roof sandwich board in place; 4. then the female port of the right part of the second metal roof panel core plate corresponds to the sub-port of the left part of the first metal roof panel core plate, and the second metal roof panel core plate and the first metal roof panel core plate are inserted and installed; 5. and repeating the steps to realize the installation of the metal roof sandwich board. The metal roof sandwich panel in the prior art has the advantages that: the roof sandwich board is connected through the primary and secondary ports in an inserting mode, the connecting nails can be hidden, and the roof sandwich board has the advantages of attractive appearance, no nail exposure and good water spraying performance. However, the prior art metal roofing sandwich panels have a number of disadvantages. The metal roof sandwich panel in the prior art has the following defects:

1. the waterproof performance is poor. Because the installation direction of the metal roof sandwich panel is from right to left, the female port of the left roof sandwich panel is inserted into the sub-port of the right roof sandwich panel by turning. There is no sealing material between the metal plates, so the connection water-proof performance is very poor. When the roof accumulated water overflows the wave crest of the roof panel, the rainwater can enter the room from the joint to cause water leakage.

2. The quality is not easy to guarantee. When the processing quality of the product has defects, namely, the small overlapping edge on the right side of the roof sandwich panel is corrugated by the roll forming of the profiling machine set, so that the overlapping quality is influenced.

3. And (4) extrusion deformation defect. When the self-tapping screw is installed, the tightness of the self-tapping screw is not easy to control. When the self-tapping screw is too tight, the core material at the position of the sub-opening of the roof sandwich panel is extruded and damaged, and the right roof sandwich panel cannot be installed; when the self-tapping screw is too loose, potential safety hazards of the roof sandwich panel can be caused, the roof sandwich panel is easy to loosen by wind, and the nail hole is torn and damaged.

4. The strength of the core material is low. The inherent defect of the roof sandwich panel in the prior art is that the strength of the core material at the seam allowance of the roof panel is low; the strength and hardness of the heat-insulating core material of the seam allowance of the roof panel sandwich panel in the prior art are very low, and the heat-insulating core material is not enough to bear the fastening force of a self-tapping screw. Therefore, when the seam allowance self-tapping screws are fastened slightly tightly, the seam allowance of the roof sandwich panel is seriously deformed, the appearance is influenced, and the left roof sandwich panel cannot be installed.

5. There is a cold-hot bridge phenomenon. In the prior art, the seam allowance of the roof sandwich panel is fixed on the roof purline supporting piece through self-tapping screws. The connecting nail is communicated with the outside, so that a cold and hot bridge phenomenon is easily formed. The heat preservation and insulation effect of the roof sandwich panel is seriously affected.

6. Expanding with heat and contracting with cold. The metal roof sandwich panel in the prior art is fixed on a roof purline supporting piece through self-tapping screws. Therefore, the connection mode cannot adapt to the metal sheets of the metal roof panel, and the phenomenon of expansion with heat and contraction with cold deformation is generated under the influence of temperature. When the metal roof panel reaches a certain length, the metal panel at the connecting nail is torn or the connecting nail is sheared off; thereby the roof boarding leaks water or potential safety hazard.

The roof sandwich panel system provided by the embodiment of the invention has the following advantages:

1. the waterproof performance is good. Because the installation direction of the metal roof sandwich panel 30 is from left to right, the secondary opening of the left roof sandwich panel 30 and the primary opening of the right roof sandwich panel 30 are subjected to 360-degree vertical overlocking by special overlocking equipment. When sealant is pre-injected between the male button and the female button, rainwater cannot enter the room from the joint to cause water leakage when accumulated roof water overflows the wave crest of the roof panel. Has very good waterproof performance.

2. No extrusion deformation. The left and right metal roof sandwich panels 30 are not fastened by any self-tapping screws 50, but are clamped by the roof purlines 21 and the high-density concave sandwich panel. Therefore, there is no crush deformation.

3. The cold and hot bridge phenomenon does not exist. The sandwich board 30 is connected with the high-density concave core board through the roof purline 21 in a clamping way; self-tapping screws 50 merely secure the high density recessed core plate to the roofing purlin 21 supports. The self-tapping screw 50 is paved with heat preservation and insulation strips, so that a cold and hot bridge phenomenon cannot be formed.

4. And (4) freely stretching and retracting. The A-type metal roof sandwich panel 30 is connected with a high-density concave sandwich panel through roof purlines 21 in a clamping manner; the device is not connected and fixed with the structural support member and can freely stretch out and draw back; the metal roof sandwich panel 30 is not affected by expansion with heat and contraction with cold deformation caused by temperature change of the metal sheet. The phenomenon that the metal roof sandwich panel 30 is torn or the connecting nail is cut off can not be caused; thereby ensuring that the metal roof sandwich panel 30 does not leak water.

Further, in the embodiments shown in fig. 11 to 13, there is also an advantage that 5, the heat insulating property is better. The insulating layer on the self-tapping screws 50 that secure the flat core panel can be thicker due to the change in the shape of the peaks of the metal roof sandwich panel 30. Is more beneficial to the heat preservation performance of the joint. 6. The drainage performance is better. Because the wave crest height of the metal roof board is improved, the drainage performance of the roof board is improved. Further, in the embodiment shown in fig. 15, there is an advantage that 7, due to the addition of the sliding connection support 80, the connection strength of the wave crests of the metal roof sandwich panel 30 and the high-density flat core panel is improved. The wind lift resistance of the metal roof sandwich panel 30 is improved.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
