(57) [Abstract] [Purpose] After installing the packing between the mountain retaining wall and the abdomen, the next work can be started immediately, the transmission of force between the members can be ensured, and the work can be performed safely. . [Structure] An outer packing a in the shape of a right triangle having a vertical surface 1 that slides along a mountain retaining wall A, and engages with an uprising B,
And an inner packing b of a right-angled triangular shape having a vertical surface 7 that abuts against the mountain retaining wall facing surface of B and is engaged with and disengages from the facing surfaces of the inner and outer packings a and b. The packing a has serrated projections 3 and 3'which are slidable only downward with respect to the inner packing b.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a packing that fills the gap between the mountain retaining wall and the upholstery material for underground construction.

[0002]

[Prior Art]

 In the past, mortar was filled in a plastic bag and placed between the Yamadome wall and the abdomen.

[0003]

[Problems to be solved by the device]

 In the above-mentioned prior art, it took many days until the strength of the mortar was sufficiently expressed, and the next excavation work could not be performed. In addition, there is a problem that it is difficult to densely fill the space between the mountain retaining wall material and the uprising material. The present invention has been proposed in view of the above-mentioned problems of the prior art. The purpose of the present invention is to immediately start the next work after the packing is installed and ensure the transmission of the force between the members. The point is to provide the packing between the mountain retaining wall and the abdominal wall where the work can be safely carried out.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the packing between the retaining wall and the waving according to the present invention is a right-angled triangular outer packing having a vertical surface that slides along the retaining wall, and a packing for the waving. The inner packing has a right-angled triangular shape and has a vertical surface that abuts against the opposing surface of the mountain retaining wall, which is co-raised. It is configured by arranging a serrated protrusion that can slide only downward with respect to the packing.

[0005]

[Action]

 Since the present invention is configured as described above, the right-angled triangle-shaped inner packing is erected and the outer packing fitted between the inner packing and the mountain retaining wall is fitted from above. While hitting it with a hammer etc. to make the vertical surface of the packing closely adhere to the mountain retaining wall, slide it downward along the inclined surface of each serrated projection of the right-angled triangular inner packing, and A gap is filled between the retaining wall and the abdomen.

Immediately after the packing is installed, the next work is started.

[0007]

【Example】

 The present invention will be described below with reference to the illustrated embodiments. A is a mountain retaining wall and B is an H-shaped steel upholstery. Reference numeral a denotes an outer packing, which is formed in a groove shape including a pair of vertical surfaces 1 that abut and slide on the mountain retaining wall A, and a back inclined surface 2 that connects the vertical surfaces 1 to each other. The saw-toothed protrusions 3 in which the horizontal step portions 3a and the inclined portions 3b are alternately arranged are provided on the, and the sliding slits 4 are provided in the longitudinal direction.

Reference numeral b denotes an inner packing, which is formed in a groove shape like the outer packing a, and a locking metal member 6 which engages with the outer flange 5 of the waving B is provided on the upper portion of the inner vertical surface 7 in a protruding manner. Like the outer packing a, the back packing inclined surface 8 of the outer packing a is provided with a saw-toothed projection 3'comprising a horizontal step portion 3'a and a slanted portion 3'b, and slits along the longitudinal direction. Is provided.

Since the illustrated embodiment is configured as described above, the locking metal 6 of the inner packing b is raised and locked to the upper end of the outer flange 5 of B, and the inner packing b and the mountain retaining wall are locked. The outer packing a interposed between A and A is tapped from above with a hammer or the like to bring the vertical surface 1 of the outer packing a into close contact with the mountain retaining wall A. Therefore, the gap between the mountain retaining wall A and the abdomen B is surely filled, and it can be dealt with by adjusting the press fit degree of the outer packing according to the size of the gap. At this time, the force is surely transmitted through the respective member surfaces.

Thus, the installation of both packings A and B immediately requires the next work. The packings A and B have a structure in which they are movable only in the direction of the arrow in FIG. 4 and do not loosen due to the serrated projections 3 and 3 ', but the tightening bolts 9 prevent the packings from shifting.

[0011]

[Effect of the device]

 As described above, according to the present invention, the work of filling the gap between the mountain retaining wall and the abdomen by the packing can be easily and surely performed, and the next work can be started immediately after the packing is installed, which is extremely workable. Be improved. In addition, since the force is transmitted in terms of the members, the force is surely transmitted, which enables safe work.

According to the present invention, as described above, the gap between the mountain retaining wall and the abdomen can be simply, quickly and surely filled in the gap so that the next work can be performed immediately after the packing is installed. Therefore, the workability is remarkably improved and the construction period is shortened. Further, since the force is transmitted through the surface of the member, the force is surely transmitted and the safety of the work is improved.
