It is known that it is formed of a flange 77 having a width capable of passing through the opening of the groove 74 and a length capable of engaging with the opening edge of the groove 74 (see Japanese Patent Publication No. 3-10838).

[0003]

In the above, in order to prevent deformation of the frame 71 during the injection and foaming of polyurethane, it is necessary to use a frame
It is conceivable to increase the thickness of 71, but if this is simply performed, the frame material 71 is formed of a synthetic resin such as a hard polyvinyl chloride resin as described above, and the material cost of such a resin is reduced. Since it is expensive, the cost increases. Therefore, it is conceivable to form the frame material 71 with a foamable synthetic resin having a low material cost. However, in the case of the foamable synthetic resin, it is possible to form the engaging concave portion 74 having a complicated shape such as the internal enlarged groove 74. Can not.

The purpose of the present invention is to prevent the deformation of the frame material without increasing the cost, and to temporarily fix the frame material and the surface plate firmly even with a simple frame material shape. It is an object of the present invention to provide an assembling jig that can be used.

[0006]

In the jig for assembling a heat insulating panel according to the present invention, since the frame material is formed of a foamable synthetic resin, the material cost is low even if the thickness of the frame material is increased, so that the cost does not increase.

Further, since the engaging recess is formed by a groove having both side surfaces parallel to each other, the shape of the engaging recess is simple.

Further, since the engaging projections are formed by flat rods having arcuate end faces inscribed on both side faces of the groove and bite projections formed on these, the engaging projections are formed in the engaging recesses. When the fitting protrusion is rotated by being inserted, the protrusion is engaged with both sides of the groove, so that the engagement protrusion is engaged with the engagement recess.

[0009]

An embodiment of the present invention will be described below with reference to FIGS.

Referring to FIGS. 1-3, the insulation panel comprises:
Foamed synthetic resin frame material such as rigid expanded polystyrene 11
And a pair of aluminum surface plates 12 arranged on both sides of the frame material 11, and a foamed polyurethane insulation material 13 injected and foamed into a hollow panel formed by the frame material 11 and the surface plate 12. And

The frame member 11 includes a pair of side walls 21 and a top wall 22 extending over both ends thereof. At the lower end of the side wall 21, an L-shaped engaging ridge 23 is formed. Near the both edges of the top wall 22, a thick portion 24 is formed in a recess 25 in the center of the top wall upper surface.
Are formed, and engagement grooves 26 are formed on the upper surfaces of the thick portions 24, respectively. Both side surfaces of the engagement groove 26 are vertical, parallel to each other, and flat.

The upper edge of the surface plate 12 is formed with an inverted U-shaped bent edge 27 which is engaged with the ridge 23.

The assembling jig includes a clamp 31 and a clamp 32 for clamping the surface plate 12 to the frame member 11 with the clamp 31.

The clamp 31 is provided at the bent edge portions 27 of the both face plates 12.
The main body 33 has a gate-shaped sub-body 34 which is fixed upside down at the center of the lower surface of the top wall of the main body 33 and is smaller than the main body 33, but is also smaller than the main body 33.

In FIG. 1, a U-shaped longitudinal notch 35 extending from the near side to the front side is formed near the right edge of the top wall of the main body 33. Further, a vertical notch 36 is formed on the left side wall of the main body 33 over the entire height thereof, and a U-shaped left and right notch 37 communicating with the upper end thereof is formed. . In the lower half of the vertical notch 36, a widened portion 38 is formed. On the bottom wall of the sub-body 34, a left-right notch 39 is formed that matches the left-right notch 37 when viewed from a plane.

The clamp 32 includes a tie rod 42 composed of a vertical threaded rod having a vertical annular head 41, and a horizontal pin 43 inserted into the head 41 so that both ends protrude.
And a gate-shaped stopper 44 fixed so as to straddle both end protruding portions of the pin 43, and a round bar-shaped handle 45 fixed orthogonally to the top of the stopper 44.

At the lower end of the tie rod 42, an engaging projection 46 made of a flat bar having two parallel surfaces is provided with a notch 47 at the lower end.
Is formed. As shown in detail in FIG. 4, the diameter D of the threadless outer peripheral surface of the threaded rod is substantially equal to the interval B between both side surfaces of the engaging groove 26, and the engaging convex portion 46
It has arc-shaped end faces 48 in contact with both side faces of the engagement groove 26. The thread of the threaded rod is a biting projection 49.

At the lower end of the stopper 44, side projections 51 each having an arc-shaped outer surface centered on the pin 43 are provided.

The temporary fixing operation is performed in the following procedure. First,
As shown in FIG. 1, the engaging convex portion 46 is inserted into the engaging groove 26 with its two parallel surfaces facing the both side surfaces of the engaging groove 26. Next, the clamp 31 is slid to engage the notch 35 in the front-rear direction with the tie rod 42. In this way, FIG.
As shown in the figure, the handle 45 is rotated by about 90 degrees while being tilted. Then, the overhang portion 51 rides on the upper surface of the clamp 31 and the tie rod 42 is pulled up, and at the same time, the biting projection 49 bites into both side surfaces of the engagement groove 26. As a result, the bent edge 27 of the surface plate 12 is fastened to the engaging ridge 23 of the frame member 11 by the clamp 31.

FIGS. 5 and 6 show a frame member 61 having a shape different from that of the frame member 11 described above. Frame material 61 according to this modified example
Is a flat plate shape lacking a portion corresponding to the side wall 21 of the frame material 11, and a thick portion 62 extending at the center of the upper surface thereof has a thickness of 1 mm.
Only one engaging ridge 63 is formed on each of the left and right edges. An engagement groove 64 is formed at the center of the upper surface of the thick portion 62.

In order to temporarily fix the frame member 61 and the surface plate 12 according to this modification, as shown in FIG. 5, the clamp 31 is turned upside down and the clamp 31 is rotated 90 degrees. And
As described above, the engaging projection 46 is inserted into the engaging groove 64, the clamp 31 is slid, and the tie rod
The tie rod 42 is engaged with the notches 37, 39 in both left and right directions by inserting the stopper 42 through the widened portion 38 so that the stopper 44 passes therethrough. After that, the handle 45 may be tilted and rotated in the same procedure as described above.

[0022]

According to the present invention, even if the thickness of the frame material is increased, the material cost is low, so that the cost does not increase, and the shape of the engaging concave portion is simple. When the fitting projection is rotated by being fitted, the projection is cut into both sides of the groove, and the engagement projection is engaged with the engagement recess, so that the cost of the frame material is increased without increasing the cost. Deformation can be prevented, and even with a simple frame material shape, the frame material and the surface plate can be firmly temporarily fixed.
