Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting method and apparatus for mounting a supporting member such as sheet metal fittings to a wall body such as a mountain retaining wall or a continuous underground wall, and particularly to an outer surface of the wall body. TECHNICAL FIELD The present invention relates to a method for mounting a support member and a device therefor capable of pouring fresh concrete densely.

[0002]

2. Description of the Related Art Conventionally, a concrete formwork is attached to a wall body such as a mountain retaining wall or a continuous underground wall, and concrete is poured between the concrete formwork and the wall body to form a concrete wall. Everything is done.

By the way, the concrete formwork needs to be supported on the wall body using a concrete formwork holding device composed of sheet metal fittings, separators and the like, and the installation positions thereof are arranged at predetermined intervals on the wall body. Although it is customary to use the position of the metal pillars, it is sometimes necessary to arrange the concrete form holding device at an intermediate position between the adjacent metal pillars.

Therefore, the inventors of the present invention previously attached a cross member between adjacent metal stanchions, for example, as shown in Japanese Patent Application No. 8-73121, and attach a sheet metal fitting to the cross member. A support member attaching device for attaching the support member has been proposed.

[0005]

SUMMARY OF THE INVENTION The support member mounting device previously proposed by the inventors of the present invention is applicable to the case where the installation intervals of the metal columns are wide and the installation intervals of the metal columns are not constant. However, since the concrete form holders can be arranged at regular intervals, there are many advantages such as being able to stably hold the concrete form.

However, since the conventional cross member is installed in a state in which the cross member is substantially in close contact with the metal column, the gap between the cross member and the outer surface of the wall body becomes extremely narrow or almost zero. There is a problem that when the fresh concrete is placed between the concrete formwork and the unfilled portion of the fresh concrete is generated on the lower surface side of the horizontal member.

That is, as the cross member, in order to secure a certain strength or more, it is customary to use a die member having an L-shaped cross section or a U-shaped cross section. Therefore, when pouring fresh concrete, the aggregate cannot pass through the gap between the cross member and the outer surface of the wall body, and concentrates on the cross member to form an eaves. This will hinder the wraparound of the horizontal material to the lower surface side. As a result, there is a problem in that a fresh concrete uncast portion is generated on the lower surface side of the horizontal member.

[0008] As described above, when the unfilled portion of the fresh concrete is generated on the lower surface side of the horizontal member, the strength of the concrete wall is weakened, and rainwater is exposed to the concrete by corrosion of the horizontal member exposed on the wall side. There is a problem that it easily penetrates inside the wall.

Further, in the case where the horizontal member is installed in a state in which the horizontal member is in close contact with the metal support, for example, Japanese Patent Laid-Open No. 11-2189.
When arranging the waterproof sheet as disclosed in Japanese Patent Publication No. 3 gazette, the horizontal member must be arranged so as to be wrapped from the outer surface side of the horizontal member, and there is a problem that the work is not easy.

Further, the metal columns of the wall body are not necessarily installed in a straight line, but usually have irregularities, but the horizontal members are installed in a state of being closely adhered to the irregular metal columns. In such a case, there is a problem in that the horizontal members are inclined with respect to the concrete formwork, and the supporting members such as sheet metal fittings attached to the horizontal members are not at right angles to the concrete formwork.

Therefore, in such a case, the supporting member is hit with a hammer or the like so as to be perpendicular to the concrete form, but in the case of this method, the supporting member is hit by the impact at the time of hitting. The strength of the part to be attached to the cross member decreases,
There is a possibility that the desired concrete formwork holding force may not be obtained.

[0012] The present invention has been made in view of the present situation, and can prevent generation of a fresh concrete non-casting portion on the lower surface side of a horizontal member, corrosion of the horizontal member and the inside of the concrete wall. An object of the present invention is to provide a support member mounting method and apparatus capable of preventing rainwater from entering.

Another object of the present invention is to enable the horizontal members to be parallel to the concrete formwork even when the metal columns are not arranged in a straight line, and to attach the supporting member to the horizontal members. It is to prevent the occurrence of problems such as a decrease in

Another object of the present invention is to allow the waterproof sheet to be easily arranged when the waterproof sheet is arranged along the outer surface of the wall body in a state where the strut mounting mechanism is mounted on the metal strut. Is to

Another object of the present invention is to provide a strut mounting mechanism,
It is to be easily attached to a metal column so that work can be performed from a remote location.

Another object of the present invention is to enable the connecting fitting to be used for mounting the support member.

Another object of the present invention is to make it possible to easily adjust the gap between the outer surface of the wall body and the cross member.

Still another object of the present invention is to prevent damage to the connecting portion between the intermediate mechanism and each mounting mechanism due to the impact of the poured fresh concrete.
