Detachable metal covering battenboard

Technical Field

The utility model relates to a building steel construction field especially relates to a detachable metal covering battenboard.

Background

With the vigorous popularization and application of the fabricated building in China, the metal surface sandwich panel is more and more widely applied to civil, public and industrial buildings and shows a rapidly growing trend. The metal surface sandwich board which can be applied to the roof and the wall surface is an indispensable finished product of components in an assembly type building.

Fig. 1 is a perspective view of a conventional metal faced sandwich panel, fig. 2 is an exploded view of the conventional metal faced sandwich panel, and as shown in fig. 1 and 2, a conventional detachable metal faced sandwich panel is generally composed of three parts, i.e., an outer panel 101, a core material 102, and an inner panel 103. The inner plate and the outer plate are generally made of 0.5-0.8 mm thin color galvanized steel plates, aluminum plates or stainless steel plates, and are rolled into various plate types by a machine, and the end part of the outer plate 101 is further provided with an outer plate end part folding edge 104; the core material is various, and at present, rock wool, glass wool, polyurethane, phenolic resin, foam glass and the like are mainly used. The outer plate 101, the core material 102 and the inner plate 103 are bonded together by proper interface glue under the action of certain temperature and pressure to form a metal surface sandwich plate with metal plates at two sides and a heat insulation material in the middle.

Fig. 3 is a cross-sectional view of a conventional metal-faced sandwich panel, and fig. 4 is an assembly view of the conventional metal-faced sandwich panel. As shown in fig. 3, the metal-faced sandwich panel has a sandwich panel sub-opening 105 and a sandwich panel female opening 106.

As shown in fig. 4, the connection and installation state between two metal-faced sandwich panels (an upper wall sandwich panel 201 and a lower wall sandwich panel 202) is shown. The lower wall sandwich panel 202 is fixed to the wall surface by tapping screws 205 passing through wall surface sealing strips 204 and wall surface purlin supporting members 203. The female opening of the upper wall surface sandwich panel 201 and the male opening of the lower wall surface sandwich panel 202 are butted with each other, and the female opening has an outer side downward projection, so that the tapping screw 205 can be shielded and sealed.

The wall surface vertical purlin support piece 203 is used for bearing the resistance of the dead weight of the wall panel, wind and earthquake. The heat insulation sealing strip 204 is used for heat insulation and sealing at the splicing seam of the wall surface. A self-tapping screw 205; for securing the lower wall sandwich panel 202 to the wall purlin supports.

As shown in the figure, the primary and secondary openings of the upper wall sandwich board 201 and the lower wall sandwich board 202 are designed into a certain shape, and then the two sandwich boards are connected with the wall support structure, i.e. the wall vertical purlin support member, through connecting nails, i.e. self-tapping screws, by a certain mounting sequence.

The installation sequence here is: positioning the lower wall sandwich panel 202; and a tapping screw 205 is attached to the illustrated position of the opening. Then, the female opening at the lower part of the upper wall surface sandwich plate 201 corresponds to the male opening at the upper part of the lower wall surface sandwich plate 202, and the plugging installation is carried out as shown in fig. 4; finally, the seam allowance of the upper wall surface sandwich panel 201 is fixed by using a self-tapping screw. Therefore, the installation of the wall surface sandwich board is realized.

The prior art has the advantages that: the wall surface sandwich board is connected through the primary and secondary ports in an inserting connection mode, and the connecting nails are hidden. Has the advantages of beautiful appearance, no nail exposure and good waterproof performance.

The defects of the prior art are as follows:

1) the installation direction of the wall surface sandwich board can only be from bottom to top, but not from top to bottom.

2) The sandwich panel in the middle of the wall body is very difficult to disassemble or replace. If a sandwich panel in the middle of a wall body is damaged and needs to be removed and replaced, all the sandwich panels on the upper part of the panel need to be removed and replaced. The later maintenance and repair of the wall surface sandwich panel are very difficult.

3) 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 sandwich panel is extruded and damaged, and the upper sandwich panel cannot be installed; when the self-tapping screw is too loose, potential safety hazards of the sandwich board can be caused, the sandwich board is easy to be loosened by wind blowing, and a nail hole is torn and damaged.
