  Next, the heat insulating panels 1, 1 connected by the vertical side portion 71 b of the L-shaped metal fitting 71 and the plate-like connecting member 21 are fixed by screwing a fixing bolt 73 into the bolt insertion hole 15. In addition, when a worker forms a wall, when forming a ceiling, which will be described later, similarly, according to the situation and environment of the construction site, each procedure for forming a wall and each procedure for forming a ceiling are performed. There is no problem even if it is replaced appropriately.

  Next, the worker connects the heat insulating panel 1 that forms the ceiling and the heat insulating panel 1 that forms the wall at the upper part of the heat insulating panel 1 that is erected as a wall inside the building.

  At that time, the connection structure is a connection structure of the heat insulation panel 1 that is connected via the rod-like connection member 22 in a state in which the bar connection recesses 14b and 14b in the both heat insulation panels 1 and 1 are abutted. The worker applies adhesive to the groove 23 formed in the longitudinal direction of the rod-like connecting member 22 in an upper and lower direction in a substantially H shape in cross section, and further applies the adhesive to the peripheral wall portion of the rod-like connecting member 22. By apply | coating, heat insulation panels 1 are adhere | attached through an adhesive agent.

  Accordingly, the position and posture of the rod-like connecting member 22 can be maintained with high accuracy, and the entire surface can be surely brought into close contact with the concave and convex portions. As a result, it is possible to prevent the formation of unnecessary voids in the connection portion and to obtain a good finish in terms of appearance and connection strength. In particular, when the heat insulating structure composed of the upper wall portion and the ceiling end portion is integrally formed, it is possible to obtain a connection structure for the heat insulating panels 1 and 1 having a connection strength that sufficiently satisfies construction requirements.

  The adhesive applied to the peripheral wall portion of the rod-shaped connecting member 22 also serves as a sealing agent that seals the gap between the heat insulating panels 1.

  Further, the protrusion 25 of the rod-shaped connecting member 22 is interposed between the spacer, that is, when the portion of the heat insulation panel 1 excluding the connection concave portion 14 and the portion of the heat insulation panel 1 excluding the connection concave portion 14 are connected with an interval. Since it functions as a thin piece to be sandwiched and forms a certain gap, as described above, when sealing the gap between the heat insulating panels 1 (including the gap formed by the protrusion 25), the gap is sealed. Since the filling of the adhesive also serving as the agent can be promoted and the position and posture of the rod-like connecting member 22 can be adjusted, the construction accuracy can be maintained with higher accuracy and the entire surface can be reliably adhered.

  As a result, the connection portion between the portion of the heat insulation panel 1 excluding the connection concave portion 14 and the portion of the heat insulation panel 1 excluding the connection concave portion 14 is also reliably sealed, thereby preventing the formation of unnecessary voids in the connection portion. In addition, a good finish can be obtained in terms of connection strength. In particular, when the heat insulating structure composed of the wall upper portion and the ceiling end portion is integrally formed, a connection structure of the heat insulating panel 1 having a connection strength that sufficiently satisfies the construction requirements can be obtained.

  Further, in the heat insulating structure having the connection structure of the heat insulating panels 1 and 1 configured as described above and the wall upper part and the ceiling end part integrally, the worker connects the rod-like shape above the substantially H-shaped cross section. A screw 24 is driven toward the center in a groove 23 formed in the longitudinal direction of the member 22.

  From this, the position and posture of the rod-like connecting member 22 can be maintained with higher accuracy, and the entire surface can be more securely brought into close contact with each other to be unevenly fitted. As a result, it is possible to prevent the formation of unnecessary voids in the connection portion and to obtain a good finish in terms of appearance and connection strength. In particular, when the heat insulating structure composed of the wall upper part and the ceiling end part is integrally formed, a connection structure of the heat insulating panels 1 and 1 having a connection strength that more fully satisfies the construction requirements can be obtained.

  Next, the worker forms a ceiling using the heat insulating panel 1.

  The worker who constructs the ceiling using the heat insulation panel 1 first prepares an indoor aerial work vehicle or the like, and, as shown in FIG. 5, places the heat insulation panel 1 on the beams or girders of the building forming the ceiling. A ceiling suspension member 50 for suspension is suspended and provided.

  An operator suspends the ceiling suspension member 50 by attaching the metal fittings constituting the ceiling suspension member 50 in order.

  First, the worker attaches and fixes the hanging bracket 51 to the beam or girder of the building. Next, all screw bolts 52 are screwed into the screw holes of the hanging metal fitting 51 and connected. Next, the lower part of all the screw bolts 52 connected to the suspension fitting 51 is screwed into the screw hole above the long nut 53 and connected. Next, the upper part of all screw bolts 52 is screwed into and connected to the screw hole below the long nut 53. The lower part of all the screw bolts 52, the upper part of which is connected to the long nut 53, is screwed and connected to the upper screw hole of the turnbuckle 54 via a hexagonal nut.

  Next, the worker screws and connects the upper screw portion of the eyebolt 55 to the lower screw hole of the turnbuckle 54. Next, a hexagon bolt is inserted through the fixing hole portion below the eyebolt 55, the fixing hole portion of the A-shaped buckle hanging bracket 56 and the fixing hole portion of the S-shaped buckle hanging bracket 57, and the hexagon nut is inserted. Are screwed into the threaded portion of the hex bolt, and the eye bolt 55, the A-shaped buckle hanging bracket 56, and the S-shaped buckle hanging bracket 57 are clamped by clamping the hex bolt head and the hex nut.

  Further, the worker engages the upper flange portion of the ceiling reinforcing bracket 58 with the lower flange portion of the A-shaped buckle hanging bracket 56, and is substantially Z-shaped in side view with the lower flange portion of the S-shaped buckle hanging bracket 57. Screw together with the vertical plate portion of the Z-shaped panel mounting bracket 62 and fix.

  In addition, the worker has a substantially hook-like shape in a side view fixed to one of the heat insulating panels 1 with a bolt 16 in a state where the lower flange portion of the ceiling reinforcing metal fitting 58 is in contact with the joint portion of each heat insulating panel 1, 1. The handle rod-shaped flange portion of the handle rod-shaped panel mounting bracket 61 is engaged with the standing portion of the flange portion below the ceiling reinforcing bracket 58 and fixed with a taper bracket.

  The worker brings the vertical plate portion of the Z-shaped panel mounting bracket 62 having a substantially Z-shape in side view fixed to the other heat insulating panel 1 with the bolt 16 and the vertical plate portion of the ceiling reinforcing bracket 58 into contact with the screw. Stop and fix.

  In order to suspend the heat insulation panel 1 in this manner, the ceiling is suspended by connecting each heat insulation panel 1 to the ceiling suspension member 50 that is suspended and provided as shown in FIGS. 4 and 5. Form.

  In that case, since the connection member 20 of each heat insulation panel 1 which forms a ceiling was comprised from the plate-shaped connection member 21 of cross-sectional view substantially rectangular shape, the shape of the connection member 20 becomes simple and the heat insulation panels 1 are mutually connected to the plate connection recessed part 14a. Since the connection is made via the plate-like connection member 21 in a state where the two are in contact with each other, the strength of the connection portion can be improved.

  Further, when the wall upper part, the ceiling end part, and the ceiling are integrally formed using each heat insulating panel 1, the connection member 20 includes a plate-like connection member 21 having a substantially rectangular cross-sectional view and a substantially H-shaped cross-sectional view. Since it is composed of the rod-shaped connecting member 22, the shape of the connecting member 20 is simple, and the heat-insulating panels 1 are connected to each other with the plate-shaped connecting member 21 or the plate-connecting recessed portion 14 b in a state where the plate-connecting recessed portion 14 a is abutted. Since the connection is made via the rod-shaped connection member 22 having a substantially H shape in cross section, the strength of the connection portion can be improved.

  Since each of the above-mentioned connecting portions is sealed with a sealing agent that also serves as an adhesive via the connecting member 20, it is reliably closed and improves the heat insulating performance of the heat insulating structure formed by each heat insulating panel 1. Can be made.

  Further, the heat insulating panel 1 is provided with a flat bar 31 between one side of the pair of surface materials 11 and the heat insulating core material 13 and has a bolt insertion hole 15 for locking the ceiling hanging member 50. Since the heat insulation panels 1 are connected to each other through the plate connection member 21 with the plate connection recesses 14a being in contact with each other, in particular, each heat insulation panel 1 is used to hang from a beam or girder of a building. When building the ceiling, there is no risk that the electrical construction worker who performs wiring etc. on the back of the ceiling will bring damage to the connection part of each heat insulating panel 1 even if they bring tools and pass through the ceiling part. It can move at the shortest distance, and as a result, workability is improved and the construction period can be shortened.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the specific embodiments, and various modifications and changes can be made within the scope of the gist of the present invention described in the claims. It can be changed.

  For example, in the above-described embodiment, the rod-like connecting member 22 is a member having a substantially H shape in cross section as shown in FIG. 3, but is a member having a substantially hexagonal shape in cross section as shown in FIG. You can also. FIG. 7 is a cross-sectional view taken along line BB in FIG. 1 when a rod-shaped connecting member 220 having a substantially hexagonal shape in cross-section is used.

  The rod-shaped connecting member 220 is a rod-shaped member having a substantially hexagonal shape in cross section, and is a member for connecting the heat insulating panel 1 and the heat insulating panel 1.

  The material of the rod-like connecting member 220 having a substantially hexagonal shape in cross section is made of polystyrene or the like, similar to the material of the rod-like connecting member 22 having a substantially H shape in cross section. For example, when foaming a thermoplastic resin polystyrene, it is made of polystyrene obtained by foaming 2 to 4 times. The rod-like connecting member 220 is formed of 2 to 4 times expanded polystyrene, so that it has sufficient strength and rigidity even when used as a connecting member.

  As shown in FIG. 7, the rod-shaped connecting member 220 is formed by applying an adhesive on the connecting surfaces 221 and 221 constituting the upper and lower surfaces of the rod-shaped connecting member 220 in a planar manner, and the rod-shaped connecting member 220 is made elastic by the connecting recess 14. It can be tightly integrated by pushing it into the connection recess 14 by using it. From this, the heat insulation panel 1 which adhere | attaches heat insulation panels 1 and integrally forms the heat insulation structure which consists of a wall upper part and a ceiling edge part as shown to Fig.7 (a) and FIG.7 (b). It can be set as a connection structure.

  In particular, in the connection structure of the heat insulation panel 1 described above, as shown in FIGS. 7A and 7B, the connection surface 221 constituting the upper side of the rod-like connection member 220 from above the surface material 11 of the heat insulation panel 1. The screw 24 is screwed toward the center of the wall, penetrates the center of the rod-like connecting member 220, and reaches the heat insulation core member 13 of the heat insulation panel 1 constituting the wall. It can be set as the connection structure of the heat insulation panel 1 which forms the heat insulation structure which consists of more reliably integrally.

  As shown in FIG. 7B, the depth when the screw 24 is screwed in the other embodiment penetrates the rod-shaped connecting member 220 from the surface material 11 of the heat insulating panel 1 and forms a wall. Although it is the length which contacts 1 heat insulation core material 13, it may be screwed in into the heat insulation core material 13 of the heat insulation panel 1 which comprises a wall.

  In addition, the rod-like connecting member 220 has a heat insulating structure composed of an upper portion of the wall and a ceiling end portion in particular because the connecting surfaces 221 and 221 constituting the upper and lower surfaces and the connecting concave portions 14 are in close contact with each other over a wide range. It can be set as the connection structure of the heat insulation panel 1 formed reliably integrally.

  Further, as shown in FIG. 7A and the like, the rod-shaped connecting member 220 has a protruding portion 222 formed therein. The protrusion 222 is tightly integrated with each of the heat insulation cores 13 and 13 by being pushed into the connection recess 14 by the elasticity of the connection recess 14 formed in the heat insulation core 13 together with the connection surface 221 described above. .

  That is, since the connecting surfaces 221 and 221 and the left and right projecting portions 222 and 222 constituting the upper and lower surfaces and the respective connecting recesses 14 are in close contact with each other, the rod-shaped connecting member 220 has an upper wall portion and a ceiling end portion. It can be set as the connection structure of the heat insulation panel 1 which forms the heat insulation structure which consists of more reliably integrally.

  Further, since the shape of the tip of the projecting portion 222 is convex, the tip of the projecting portion 222 has a spacer, that is, a portion of the heat insulating panel 1 excluding the connection concave portion 14 and the heat insulating panel 1. When connecting with a space apart from the portion excluding the connecting recess 14, it has a function as a thin piece sandwiched therebetween, and forms a certain gap.

  Since the tip of the projecting portion 222 forms a certain gap, the adhesive between the connecting surfaces 221 of the rod-shaped connecting member 220 and the sealing agent applied to the projecting portion 222 is used between the heat insulating panels 1. When sealing the gap (including the gap formed by the tip of the projecting portion 222), it is facilitated that the gap is filled with a sealing agent, and the position and posture of the rod-like connecting member 220 can be adjusted. . Therefore, the position and posture of the rod-like connecting member 220 can be adjusted, so that the construction accuracy can be maintained with higher accuracy and the entire surface can be reliably adhered.

  As a result, even if the substantially hexagonal rod-shaped connecting member 220 in cross section is used as the connecting member, the connecting portion between the portion excluding the connecting recess 14 of the heat insulating panel 1 and the portion excluding the connecting recess 14 of the heat insulating panel 1 is reliably sealed. As a result, it is possible to prevent the formation of unnecessary voids in the connection portion and to obtain a good finish in terms of appearance and connection strength. In particular, when the heat insulating structure composed of the wall upper portion and the ceiling end portion is integrally formed, a connection structure of the heat insulating panel 1 having a connection strength that sufficiently satisfies the construction requirements can be obtained.
