When connecting refractory panels filled with a material, a concavity parallel to the surface plate is formed on the connecting side end face of the core material of the adjacent refractory panels, and both refractory panels adjacent to the concavity are formed. The calcium silicate plate is fitted so as to be parallel to the surface plate over the core material, and a laminated portion is provided to overlap and laminate the surface plates of the adjacent fireproof panels in the panel thickness direction.

In the previous stage before reaching the concave groove, the protruding sides were formed by bending toward the connecting end surface of the adjacent fireproof panel, and the protruding sides of the adjacent fireproof panel were laminated in the panel thickness direction. 2. The connection part structure of a fireproof panel according to claim 1, wherein the structure is a laminated part, and the laminated part is fixed using screws.
In the invention of claim 3, ceramic fibers are interposed between the connecting side end faces of the cores of adjacent fireproof panels so as to reach the surface plate from the calcium silicate plate in a state orthogonal to the calcium silicate plate.

請求項１の発明とすることにより、火災等の高温下において、熱により表面板が芯材から剥がれたり熱膨張変形したりしても、耐火パネルの連結部は、隣接する両方の耐火パネルの芯材に亘るように配されたケイ酸カルシウム板によって、加熱側面から非加熱側面への火炎や熱の通過経路が確実に遮断されることになる。しかも、前記ケイ酸カルシウム板は、芯材の連結側端面に形成された凹溝に嵌合されることによって、隣接する両方の耐火パネルの芯材に亘るように配される構成であるから、高熱下であっても、ケイ酸カルシウム板が芯材から外れてしまったり、ケイ酸カルシウム板と芯材との間に隙間が生じてしまう惧れがなく、而して、耐火性能に優れた連結部構造とすることができる。 According to the invention of claim 1, even when the surface plate is peeled off from the core material due to heat or thermally expanded under high temperature such as a fire, the connection portion of the fireproof panels is not Thus the calcium silicate plate disposed to span the core material, passing path of the flame and heat from the heating side to the non-heating side is to be reliably blocked. Moreover, since the calcium silicate plate is arranged so as to extend over the core material of both adjacent fireproof panels by being fitted into a concave groove formed on the connection side end surface of the core material, Even under high heat, there is no fear that the calcium silicate plate will come off the core material or that there will be a gap between the calcium silicate plate and the core material. It can be set as a connection part structure.

１７は前記耐火パネル２同士の連結部であって、該連結部１７において、隣接する耐火パネル２の表面板１４同士は雄雌状に係合するように構成されている。つまり、耐火パネル２の一方の連結側端部（図３、４において右側端部）における二枚の表面板１４は、該耐火パネル２の芯材１５の連結側端面１５ａよりも隣接する耐火パネル２に向けて直線状に延びてから芯材１５の連結側端面１５ａに戻るように折り返されており、これにより、隣接する耐火パネル２に向けて突出する突出部１４ａが形成されている。また、耐火パネル２の他方の連結側端部（図３、４において左側端部）は、耐火パネル２の厚み方向の寸法が他の部分よりも若干狭くなるように設計されており、これにより他方の連結側端部において二枚の表面板１４は、他の部分よりも厚み方向内側に凹んだ凹部１４ｂに形成されている。そして、該凹部１４ｂの厚み方向外側に隣接する耐火パネル２の突出部１４ａが係合することで、隣接する耐火パネル２の表面板１４同士が雄雌状に係合するようになっており、これによって隣接する耐火パネル２の表面板１４同士にパネル厚方向に重なり合って積層する積層部が設けられている。 Reference numeral 17 denotes a connecting portion between the fireproof panels 2. In the connecting portion 17, the surface plates 14 of the adjacent fireproof panels 2 are configured to engage in a male-female manner. That is, the two surface plates 14 at one of the connection side end portions (the right end portion in FIGS. 3 and 4) of the fireproof panel 2 are adjacent to the connection side end surface 15 a of the core 15 of the fireproof panel 2. 2 and then folded back so as to return to the connection side end face 15a of the core member 15, thereby forming a protruding portion 14a protruding toward the adjacent refractory panel 2. Moreover, the other connection side edge part (left side edge part in FIGS. 3 and 4) of the fireproof panel 2 is designed so that the dimension in the thickness direction of the fireproof panel 2 is slightly narrower than the other parts. At the other connection side end, the two surface plates 14 are formed in a recess 14b that is recessed inward in the thickness direction relative to the other portions. And the protrusion 14a of the fireproof panel 2 adjacent to the outer side in the thickness direction of the recess 14b is engaged, so that the surface plates 14 of the adjacent fireproof panel 2 are engaged in male and female shapes , Thereby, the laminated part which overlaps and laminates | stacks the surface plates 14 of the adjacent fireproof panel 2 on the panel thickness direction is provided .

尚、本発明は上記実施の形態に限定されないことは勿論であって、例えば、隣接する耐火パネル２の連結部１７において表面板１４同士を係合するにあたり、図７（Ａ）、（Ｂ）に示す如く、隣接する両方の耐火パネル２の表面板１４の連結側端部に突出辺１４ｃ或いは１４ｄを形成し、これら突出辺１４ｃ或いは１４ｄ同士をパネル厚方向に重ね合わせて積層されたものが螺子２１或いは２２で止着する構成にすることもできる。さらにこれらのものにおいて、螺子２１或いは２２の止着部分にジョイナー２３或いは２４を装着しても良い。 Of course, the present invention is not limited to the above-described embodiment. For example, when the surface plates 14 are engaged with each other in the connecting portion 17 of the adjacent refractory panel 2, FIGS. As shown in FIG. 4, the projecting sides 14c or 14d are formed at the connecting side end portions of the surface plates 14 of both adjacent refractory panels 2, and the projecting sides 14c or 14d are laminated in the panel thickness direction. It can also be set as the structure fastened with the screw 21 or 22. Further, in these devices, a joiner 23 or 24 may be attached to the fastening portion of the screw 21 or 22.
