Description

[Detailed Description of the Invention] This invention relates to a composite fireproof panel comprising a fireproof panel made of a fireproof material and a covering panel covering the same.

Fire-resistant panels such as lightweight cellular concrete boards, asbestos-cement calcium silicate boards, and asbestos-cement boards are often used for the exterior walls of buildings because of their excellent durability, fire resistance, and heat insulation properties. However, the above-mentioned fireproof panels have the drawbacks that they are brittle and easily damaged during construction, especially at the corners, and are highly water-absorbing, allowing water to permeate through them, and lack color, which makes them difficult to match with surrounding buildings. Furthermore, for example, lightweight aerated concrete plates are generally manufactured by pouring inorganic slurry into a tank slightly deeper than the width of the plate, solidifying it, and cutting it with piano wire to produce a large number of panels. All I could get was a poor angle. Therefore, as shown in FIG. 1, when installing the fireproof panel 20 on the bracket 12 fixed to the frame 11 of the building during construction on the wall of the building, the verticality of the fireproof panel 20 is adjusted using the bracket 13. Since the width of the horizontal joints 21 between the upper and lower fireproof panels 20 is uneven and unsightly,
After installing the fireproof panel 20, it is necessary to grind the upper and lower edges of the fireproof panel with a grinder to make the horizontal joint width uniform, and then fill it with sealant, which increases the width of the horizontal joints and is extremely time-consuming. Ta.

This idea solves the above-mentioned conventional drawbacks.
By covering the front side of a fire-resistant panel with a covering panel, it takes advantage of the features of a fire-resistant panel while eliminating its flaws such as brittleness and water permeability, and also provides the excellent weather resistance and variety of color tones that are the features of a covered panel. The aim is to provide a composite fire-resistant panel that is useful. Furthermore, this invention aims to provide a composite fire-resistant panel that can reliably and easily equalize the joint width during construction on the walls of buildings.

However, the gist of this invention is to provide a notch extending in the longitudinal direction of the side surface at the corner of the surface and side surface of a rectangular plate-shaped fireproof panel, and to provide continuous bent pieces around the four circumferences of the main plate. A box-shaped covering panel, which is narrower in width than the fireproof panel and longer than the fireproof panel, is attached to the front side of the fireproof panel with the bent piece part fitted into the notch. It is a composite fireproof panel characterized by fixed.

The fireproof panels used in this invention include lightweight aerated concrete boards, asbestos-cement calcium silicate boards, asbestos-cement boards, PC boards, gypsum boards, and glass fiber-reinforced gypsum boards. In addition, as the coated panel in the present invention, a copper plate, a stainless steel plate, a colored iron plate, an aluminum plate, an enameled aluminum plate, an enameled iron plate, an enameled aluminum plated steel plate, a synthetic resin-coated steel plate, a synthetic resin plate, etc. are used.

An embodiment of this invention will be described below with reference to FIGS. 2 to 5.

At the corner between the surface 2 and side surface 3a of the fireproof panel 1 made of a rectangular lightweight aerated concrete plate,
A stepped notch 4 extending in the longitudinal direction of the side surface 3a is provided. Furthermore, a semicircular groove 5 is provided in the side surface 3a of the fireproof panel 1, extending in the longitudinal direction of the side surface 3a. The covering panel 6, which is made of an enamel panel made by enameling both sides of a steel plate, has a box shape with bent pieces 8 arranged around the four circumferences of a rectangular main plate part 7, and the width W of the covering panel 6 is as follows. It is narrower than the width S of the fireproof panel 1, and the length L is larger than the length T of the fireproof panel 1. The covering panel 6 is fixedly attached to the front surface 2 of the fireproof panel 1 with the bent piece 8 fitted into the notch 4 of the fireproof panel 1. Further, the bent pieces 8 at the longitudinal ends of the covering panel 6 are in a state of covering a part of the end surface 3b of the fireproof panel 1. The covering panel 6 and the fireproof panel 1 are fixed by fixing the surface 2 parts of the fireproof panel 1 to the main plate part 7 of the covering panel 6.
At the same time, apply adhesive to the back side of the folded piece 8.
This is done by driving a nail 9 into the fireproof panel 1 through the nail 9, but one of the adhesive and the nail 9 may be omitted, or a connecting piece (not shown) may be attached to the bent piece 8.
Other fastening structures may be used, such as connecting the connecting piece and securing the connecting piece to the fireproof panel with nails.

In order to construct the wall surface of a building using the composite fireproof panel 10 having the above-mentioned configuration, a receiving metal fitting 1 fixed to the building frame 11 is used as shown in FIGS. 4 and 5.
2, the composite fireproof panel 10 is installed in parallel on the fireproof panel 1. At this time, a bracket 13 is placed between the bracket 12 and the lower end of the fireproof panel 1, and the composite fireproof panel 10
The vertical position and verticality of the panels 1 are adjusted, and the side surfaces 3a of adjacent fireproof panels 1 are brought into contact with each other. Since the covering panel 6 is longer than the fireproof panel 1 and its corners have good squareness, the sloping and messy upper and lower end surfaces of the fireproof panel 1 are replaced by the covering panel 6.
The width of the horizontal joints 14 formed between the folded pieces 8, 8 of the vertically adjacent composite fireproof panels 10, 10 can be made narrow and uniform. It can be made the same as the vertical joint width. The vertical joints formed between the bent pieces 8, 8 of the composite fireproof panels 10, 10 adjacent to each other on the left and right can also be made uniform in width by adjusting using the paddles 13, so the width can be made uniform by adjusting with the paddles 13. Vertical joints and horizontal joints with a wide width and perpendicular to each other are formed at the same time. After adjusting the joints, reinforcing bars are passed through the cylindrical space formed in the groove 5 of the fireproof panel 1, and the reinforcing bars are welded and fixed to the frame structure, and mortar is filled for connection, and a sealant is applied to the joints. Just fill it up.

In addition, although the case where the front shape of the fireproof panel 1 is rectangular has been explained above, the rectangular plate-shaped fireproof panel according to this invention may also have a large notch for attaching a window sash or a square one. shall be included in the Furthermore, this invention is not limited to the above embodiments; for example, the notch 4 of the fireproof panel 1 may be cut out from the surface side of the fireproof panel until it reaches the groove 5; This idea can also be applied to fireproof panels.

As explained above, according to this invention, the disadvantages of fireproof panels such as brittleness and water permeability are eliminated, and the durability and heat insulation properties are taken advantage of, while the excellent features of coated panels such as enamel panels are A composite fireproof panel with weather resistance and a variety of colors can be obtained. In addition, the front side of the fireproof panel is covered with a box-shaped covering panel with folded pieces on all four sides, and joints are formed between the folded pieces of adjacent covering panels, so that the joints are uniform. To easily obtain wide and orthogonal horizontal joints and vertical joints, and to obtain a wall structure with an excellent appearance in which the joints are arranged horizontally and vertically in an orderly manner.
