[0008]

DETAILED DESCRIPTION OF THE INVENTION Next, details of the joint material supporting member according to the present invention will be described with reference to the accompanying drawings.

In FIG. 1, reference numeral 10 is a conventionally known joint material main body, which is formed of a synthetic resin foam and has a reinforcing cap 11 on its upper portion. In the joint construction method to which the present invention is applied, conventionally used conventional support legs or fixing mortar is not used, but it is attached to the base with butyl rubber or double-sided adhesive tape 12 or the like to be interposed on the lower surface of the joint material body 10. And the side surface is supported by the joint material supporting member 20 described below.

The joint material supporting member 20 has a hollow structure, and is preferably blow-molded with a synthetic resin material. A fluid such as water, mortar, concrete, sand, gravel, etc. is poured into the joint material 20 as a heavy weight. To use. Further, although the handle structure 22 is formed so as to be convenient to carry, it is preferable that the handle 22 has a structure having no protruding portion from the outer surface as shown in FIG. The injection port 2
The 1 and the handle structure 22 can be provided on any surface even if they are not at the positions shown.

It is also preferable that the bottom surface of the joint material supporting member 20 is formed with irregularities so that a rubber material 23 for slip prevention is fitted therein. The rubber material 23 may be in the form of a single plate material having concaves and convexes on the lower surface.

Further, a mode in which a pressure sensitive adhesive coated with a release paper is provided on the bottom surface of the joint material supporting member 20 is also useful for preventing lateral deviation when arranged on the base.

Further, the joint material supporting member 20 is not limited to the outer shape shown in the figure and can be designed arbitrarily, but is basically a cubic shape having no unevenness on the surface, and in the mode of the stepped shape shown in the figure. In the case of management storage, it is preferable that the shape is a similar shape or a shape that can be stacked alternately.

The joint material supporting member 20 according to the present invention described above can be integrally molded by a blow molding method, a vacuum molding method or the like. However, an extrusion molded material such as a mold material is cut into an appropriate length. It is also possible to adopt a structure in which lid members are attached to both ends thereof. In such a manufacturing mode, the water inlet 21 and the handle structure 22 are arranged on the lid member side.

In FIG. 1, reference numeral 30 is a plate member for height adjustment, which is formed of a synthetic resin material or the like having a strength that does not easily deform.

The joint material has various heights corresponding to the thickness of the holding concrete or the like. Therefore, if the joint material supporting member 20 is of only one type having a constant height, a disadvantage occurs. That is, if the height of the joint material supporting member 20 is higher than that of the joint material, it hinders the work of smoothing the upper surface of the placed concrete, and conversely the height does not reach the height of the cap 11. If this is the case, the jointing material main body 10 may be bent outward in the vertical direction due to the pressure at the time of placing concrete, and the upper surface of the cap 11 may be inclined. In order to prevent such a situation, the side surface support by the joint material supporting member 11 is performed by the joint material main body 10
Must be performed over the entire area from the lower end to the position of the cap 11. For this purpose, it is necessary to prepare the kind of the joint material supporting member 10 according to the height of the joint material. However, in this case, the number of the joint material supporting members 20 to be prepared becomes too large, It will be very complicated to sort when storing, transporting and installing.

In view of the above, the joint material supporting member 20 according to the present invention is provided with the mounting structure 31 for the height adjusting plate member 30, and the plate member selected according to the height of the joint member. 30 is attached.

The mounting structure 31 for the plate member 30 for height adjustment is provided with a groove on the side surface of the joint material supporting member 20 as shown in FIG. 3 in addition to the engaging hole as shown in FIG. Various modes such as a structure in which the protrusion 33 on the plate member 30 side is fitted in the groove 32 can be selected.

Further, as shown in FIG. 2, it is preferable that a recess 34 for absorbing the protruding portion of the cap 11 is formed in an upper portion of the plate member 30 for height adjustment.

Further, as shown in FIG. 4, by using the plate material 30 as a member for connection, the joint material supporting members 20 are arranged in a dot shape to support the joint material and to pour concrete. A joint construction method can be performed.

[0021]

According to the present invention, the joint material supporting member 20 is used.
Since the height of the joint material can be adjusted simply by attaching the plate member 30 for height adjustment to the joint, only one kind of joint material supporting member 20 needs to be prepared, which is convenient for storage, transportation and construction. It has excellent properties and achieves the above-mentioned purpose.
