Description

  The present invention relates to a connection structure of a heat insulating panel used for construction of a heat insulating wall or ceiling or a heat insulating partition in, for example, a clean room or a refrigerator / freezer warehouse.

  A general heat insulation panel used for construction of a heat insulating wall or ceiling is generally a pair of surface plates arranged in parallel with each other at a predetermined interval, and a peripheral portion between the pair of surface plates. Alternatively, foam insulation such as polyurethane foam is filled in a space formed by a frame member attached to the end of one surface plate close to the peripheral edge and the frame member and the pair of surface plates. It consists of a core material.

And, for example, when connecting heat insulation panels for walls arranged in a straight line on the same plane, or a heat insulation panel for walls and a heat insulation panel for ceiling, means for abutting the frame members of both heat insulation panels At this time, in order to obtain a connection structure having a good appearance without appearance and appearance, both panels should not be displaced from each other, and the foam insulation core material should be foamed. It is a very important required performance to prevent the frame member from shifting due to foaming pressure when filling. Conventionally, as a connection structure of a heat insulating panel that meets such required performance, a female frame member and a male frame member that are fitted to each other are fitted to both heat insulating panels, and the female and male frame members are fitted to each other. Thus, there has been proposed one in which both the heat insulating panels are positioned and the bent end portions of the surface material of the heat insulating panels are sandwiched and fixed between both end portions of the male and female frame members (see, for example, Patent Document 1). ).

Moreover, like what is shown in said patent document 1, by mounting | wearing both heat insulation panels with the female frame member and male frame member which carry out uneven fitting with each other, and fitting these female and male frame members with unevenness mutually, While positioning both heat insulation panels, by inserting the bent end portion of the surface material of the heat insulation panel into the groove formed in the male and female frame members, the frame members are opposed to the foaming pressure so as not to shift and move. Have also been proposed (see, for example, Patent Document 2).

  However, in the conventional heat insulation panel connection structure disclosed in Patent Documents 1 and 2, both of the male and female frame members are required, and the two types of male and female frame members need to be used separately for each heat insulation panel. There is. As a result, there is a problem in that the cost of the connection structure of the frame member and by extension, the heat insulating panel is likely to increase, and the number of management of the frame member increases. Furthermore, in the connection structure as shown in Patent Document 1 in which the bent end portion of the surface material of the heat insulating panel is sandwiched and fixed between both end portions of the male and female frame members, the frame member is pushed and displaced due to foaming pressure. As a result, there is a problem in that the two types of male and female frame members cannot be fitted in an uneven state in close contact with each other, resulting in an unnatural finish such as unnecessary clearance at the connecting portion.

  The present invention has been made in view of the above-described circumstances, and it is possible to reduce the position and inclination of the frame member due to foaming pressure while reducing the cost and simplifying the material management by using one type of frame member. It aims at providing the connection structure of the heat insulation panel which can prevent reliably and can obtain the good-looking finish.

  In order to achieve the above object, a heat insulating panel connection structure according to the present invention includes a pair of surface plates arranged in parallel to each other at a predetermined interval, and a peripheral portion or a peripheral portion between the pair of surface plates. The heat insulating panels are assembled from a frame member attached to an end portion of one surface plate adjacent to each other and a foam heat insulating core material foam-filled in a space formed by the frame member and the pair of surface plates. It is the connection structure of the heat insulation panel which connects in the state which faced each said frame member of each panel, Comprising: The frame member of both said panels is for edge part insertion of the said pair of surface plate in the both ends of a width direction, respectively Grooves are formed, and protrusions projecting outward from the both end portions are formed in the respective intermediate portions. When these two frame members are butt-connected, one frame member The protrusion of the other frame member It is characterized in being formed in the male and female compatible type having the same shape to fit concave portion parts back side.

  According to the present invention having the above-described characteristic configuration, the frame members in both heat insulation panels to be connected are male and female molds of the same shape (congruent shape), and one type of frame member is attached to all the heat insulation panels. Since it can be shared for connection, not only the manufacturing cost of the frame member, but also the cost of the connection structure itself of the heat insulation panel configured using the frame member can be reduced, and the management of the frame member The number can be reduced and material management can be simplified. Moreover, it is possible to insert and fix the edge of the surface plate in the heat insulation panel in the groove of the frame member, and the frame member is not displaced or tilted by the foaming pressure, and the position accuracy of the frame member Since the posture accuracy can be made uniform, the frame members of both heat insulation panels can be securely brought into close contact with each other so that they can be unevenly fitted. It is possible to prevent the appearance from deteriorating due to irregularities in the shape of the projections and depressions, and to obtain a good finish in terms of appearance and connection strength.

In particular, at both end portions in the width direction of the frame member, a long protruding portion that protrudes sideways so as to have a width corresponding to the dimension between the inner surfaces of the pair of face plates in the heat insulating panel, and the long protruding portion When both the inner and outer sides have short projecting portions, and the short projecting portions are respectively formed with grooves for inserting the end portions of the surface plate, the both heat insulations to be connected By inserting the end of the surface plate into the groove closer to the mating heat insulation panel of the two grooves of the frame member in the panel, the gap between the insertion ends of the surface plates of both heat insulation panels is minimized. When the joint treatment such as coking is stopped, the joint treatment can be facilitated, and when the joint treatment is not performed, the gap can be made inconspicuous and the appearance can be further improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a heat insulating panel connection structure according to the present invention will be described below with reference to the drawings.
FIG. 1 shows a case where, for example, a side wall 2 for heat insulation in a refrigerator-freezer or a clean room is constructed by sequentially connecting horizontal adjacent panels among a plurality of heat insulation panels 1 arranged in parallel on the same plane. FIG.

  The heat insulation panel 1 includes, for example, a pair of surface plates 3 and 3 such as a steel plate and a SUS plate having a thickness of about 0.5 to 0.8 mm that are arranged in parallel with each other with a predetermined distance d of 45 mm. A frame member 4 mounted on a peripheral portion between the pair of surface plates 3 and 3, and a space portion formed by the frame member 4 and the pair of surface plates 3 and 3 is foam-filled, for example, foamed rigid urethane or the like The heat insulating panels 1 and 1 adjacent to each other in the horizontal direction are connected to each other with the frame members 4 and 4 in the panels 1 and 1 facing each other.

  The frame member 4 of the heat insulation panel 1 is manufactured by extrusion molding of a hard resin such as hard vinyl chloride (PVC) or hard polyethylene (PE). As clearly shown in FIG. 2, the frame member 4 corresponds to the dimension between the inner surfaces of the pair of surface plates 3 and 3 in the heat insulating panel 1, that is, the predetermined distance d described above, at both ends in the width direction. It has a long protrusion 4a that protrudes sideways so as to have a width, and two short protrusions 4b and 4b on both the inner and outer sides of this long protrusion 4a that protrude left and right. The right and left folded end portions 3a, 3a of the pair of surface plates 3, 3 of the heat insulating panel 1 can be inserted and fixed at the boundary between the two short projections 4b, 4b and the long projection 4a. End insertion grooves 4c and 4c are formed.

  In addition, a ridge portion 4d is formed in the middle portion of the frame member 4 so as to protrude outwardly from the both end portions in the width direction, and the back side of the ridge portion 4d. Is formed with a recess 4e recessed outward, and when the frame members 4 and 4 of the adjacent heat insulating panels 1 and 1 are brought into contact with each other, as shown in FIG. Both frame members 4, 4 are formed in a male-female mold having the same shape (congruent shape) so that the four ridges 4 d fit into the concave ridge 4 e on the back side of the ridge 4 d of the other frame member 4. Has been.

  As is clear from the above, since the frame members 4 and 4 in both heat insulating panels 1 and 1 to be connected are formed in a male and female combined mold of the same shape (congruent shape), two types of frame members are used. It is possible to share one kind of frame member 4 for connection of all the heat insulation panels 1 constituting the heat insulation side wall 2, so that the production cost of the frame member 4 is not limited, The cost of the connection structure itself of the heat insulating panels 1 and 1 configured using the frame member 4 can be reduced, and the number of management of the frame member 4 is reduced, so that material management at the construction site of the side wall 2 for heat insulation is performed. Can be simplified and facilitated.

Further, the folded end portions 3a, 3a of the surface plates 3, 3 in each heat insulating panel 1 can be inserted and fixed in the grooves 4c, 4c of the frame member 4, so that the foam heat insulating core material 5 such as foamed hard urethane is used. Since the frame member 4 is not displaced or tilted by the foaming pressure, the position accuracy and posture accuracy of the frame member 4 can be made uniform. The protrusions 4d and the recesses 4e of the members 4 and 4 can be reliably concavo-convexly fitted into the entire surface. As a result, it is possible to prevent unnecessary clearance from being formed in the connecting portion, and to prevent the appearance of the surface plates 3 and 3 of the both heat insulating panels 1 and 1 from becoming uneven, and in terms of connection strength in terms of appearance. It is possible to construct the heat-insulating side wall 2 with a satisfactory finish.

In particular, since both the right and left grooves 4c and 4c are formed at both ends in the width direction of the frame members 4 and 4 in the both heat insulating panels 1 and 1 to be connected. Of the grooves 4c and 4c, by inserting the folded end portions 3a and 3a of the surface plates 3 and 3 into the groove 4c closer to the heat insulating panel 1 on the other side, the surface plates 3 and 3 of the both heat insulating panels 1 and 1 are inserted. When the joint processing such as caulking is performed, the joint processing is facilitated, and when the joint processing is not performed, the clearance is made inconspicuous. The appearance can be made even better.

  FIG. 3 is an enlarged longitudinal sectional view of a main part when the connection structure of the heat insulation panel according to the present invention is applied to the connection between the heat insulation panel 1 forming the heat insulation side wall 2 and the heat insulation panel 1C forming the heat insulation ceiling 6. It is. In this case, the frame member 4 is not located at the peripheral portion between the pair of surface plates 3 and 3 of the heat insulating panel 1C on the heat insulating ceiling 6 side but at the end portion close to the peripheral portion by the surface plate 3 disposed below. Since the other configurations are the same as those of the above-described embodiment, the same reference numerals are given to the same members and the same parts, and detailed descriptions thereof are omitted.

In the case of the embodiment shown in FIG. 3, the congruent male and female combined frame members 4, 4 in the heat insulating panel 1 C on the heat insulating ceiling 6 side and the heat insulating panel 1 on the heat insulating side wall 2 side are indented. Thus, both the heat insulating panels 1 and 1C are surely positioned so that unnecessary clearance is not generated in the connecting portion, and the both panels 1 and 1C are accurately angled at right angles to obtain a good finish. be able to.

In each of the above-described embodiments, there are a long protrusion 4a and two right and left short protrusions 4b and 4b at both ends in the width direction, and two right and left short protrusions 4b and 4b. Two end insertion grooves 4c, 4c capable of inserting and fixing the right folded ends 3a, 3a of the pair of surface plates 3, 3 of the heat insulating panel 1 are formed at the boundary with the long protrusion 4a, respectively. Although the case where the frame member 4 is used has been described, as shown in FIG. 4, each of the both ends in the width direction has one long protruding portion 4 a, and one thick intermediate portion of the long protruding portion 4 a has one.
