Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention uses J
The present invention relates to a joint structure of an outer wall that can pass one hour of a fireproof structure of IS-A-1304 (fireproof test method for building structures).

[0002]

2. Description of the Related Art Generally, as a panel that passes a fireproof 1 hour test of JIS-A-1304, for example, Japanese Patent Laid-Open No. 4-304
There is 261955 publication. Further, the joint structure of the outer wall using this composite plate has been a connecting portion with a large amount of surface contact.

However, since the joint using the composite plate having such a structure has many contact surfaces, the construction is not smooth. Positioning during construction becomes difficult, and dimensional deviation occurs in the joint appearance. When exposed to high heat, the contacting parts are deformed at the same time, and a gap is easily formed, which becomes a heat weak point.
It is not easy to absorb manufacturing and construction errors. There were drawbacks such as.

[0004]

In order to eliminate such drawbacks, the present invention uses a core material such as phenol foam for the composite plate itself, and has a structure for positioning the connecting portion and a line contact structure, and is fire resistant. A joint structure is proposed which has a concavo-convex engagement structure that greatly enhances workability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a joint structure according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a vertical cross-sectional view showing a typical example of the joint structure, where A is a composite plate,
B is a joint portion, C is a sealing material, D is a fixture, and E is a body.

To explain further, the composite plate A has a sandwich structure in which a plastic foam having a fireproofing property of a semi-incombustible material or more, such as phenol foam, is integrally interposed between the front and back materials 1 and 2 as shown in FIG. And the male connecting portion 4 and the female connecting portion 11 on both side edges in the longitudinal direction.
Is provided.

That is, the surface material 1 and the back material 2 are thin metal plates such as iron, aluminum, copper, stainless steel, titanium, aluminum / zinc alloy plated steel plate, enamel steel plate, fluororesin coated steel plate, clad steel plate, sandwich steel plate, etc.
Alternatively, one kind of these coated metal plates (color metal plates) is formed into various shapes by roll forming, press forming, extrusion forming or the like.

To explain further, the male connecting portion 4 is made lower than the decorative surface portion 1a by one step, and the cover portion 1 of the female connecting portion 11 is formed.
The stepped portion 5 for accommodating 2 and the decorative surface portion 1a in the middle of the stepped portion 5
In parallel with the concave groove 6 for accommodating the head portion of the fixture D, the main convex ridges 7 for engaging, insulating, and refractory, the accommodating concave groove 8 formed in the lower layer, and the reinforcing projection 9 in the lowermost layer. It was done. In addition, 10 is a guide point for connecting the male and female connecting portions 4 and 11 with a line contact structure to facilitate positioning and construction. It is formed into a shape suitable for.

The female connecting portion 11 includes a cover portion 12 that covers the step portion 5, a point 13 that contacts the guide point 10, a main concave portion 14 that accommodates the main convex portion 7, and a reinforcing protrusion 15 that is mounted in the accommodation concave groove 8. It is composed of a sub-recess 16 for accommodating the reinforcing projection 9.

Next, a construction example will be described. An example of the joint structure as shown in FIG. 1 will now be briefly described using the composite plate A as shown in FIG. First, a drainer (not shown), a starter and the like are fixed on the frame E. Next, as shown in the drawing, the n-th stage composite plate A ₁ is fixed to the frame E by the fixture D at predetermined intervals.

Next, the upper n + 1th composite plate A ₂
The female connecting portion 11 is inserted into the male connecting portion 4 of the lower composite plate A ₁ . At this time, the guide points 10 and 13 of the male and female type connecting portions 4 and 11 are brought into line contact with each other, and
It was easy to position left and right, and the appearance of the entire wall was beautiful. By forming the sealing material C at the position shown in FIG. 2, it also has a fireproof property.

Further, for this composite plate A, JIS-A
When a 1 hour fire resistance test of -1304 was carried out, a passing performance was obtained.

Therefore, in order to construct the entire wall, it is possible to form a wall having joints of the structure according to the present invention by sequentially and repeatedly performing the above-mentioned steps.

The above description is only one example of the joint structure according to the present invention, and the guide points 10 and 1
The shape of 3 can be formed, for example, as shown in FIGS. That is, the guide point 10 is a concave stripe in the figure (a), the point 13 is a convex stripe in the figure (b), and both points are small slopes in the figure (c) to form line contact effectively. You can also do it.

Further, as a joint structure, FIG.
It can also be formed as shown in (d). That is,
(A) In the figure, the sealing material C is added at the position shown,
With a joint structure that further strengthens fireproofness and airtightness, the sealing material C is a glass mat impregnated with ammonium polyphosphate, carbon black and phenol foam,
A joint structure that foams up to 30 times and suppresses or prevents the formation of a gap between both connecting portions.
A joint structure is formed by forming a, and the fixing tool D is assisted from the groove, (c) and (d) in FIG. The joint structure is such that the step and the joint are covered with a cap device H having a detachable fitting structure including a cap F and a mounting base G.

Further, the sealing material C can be formed as shown in FIGS. 5 (a) and 5 (b). (A) The figure shows a sealant C in which a glass mat is impregnated with a refractory caulking material α,
FIG. 3B shows a corrugated cardboard structure sealing material C in which a face material is bonded to a corrugated sealing material, which is made of a material such as fire resistant joint rubber and has sufficient elasticity.

[0017]

As described above, according to the joint structure according to the present invention, construction can be extremely facilitated by forming guide points even in a complicated male and female type connecting structure. By forming the guide points, it is possible to form a flat and beautiful wall without deviation of the joint width of the wall surface and overall unevenness. The effect of the sealing material is also added, and the deformation under high heat can be significantly suppressed, so that the performance that passes the fire resistance test can be obtained. The joint structure that supplementally attaches the cerebral cervical fixture sufficiently passes the fire resistance test. Waterproof, heat-insulating, and air-tightness provides better performance than before. There are characteristics and effects.
