Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating support for a concrete wall and a concrete wall structure using the support.

[0002]

2. Description of the Related Art Conventionally, when a finishing material is applied to the surface of a concrete skeleton (insulating layer) constructed by a concrete formwork method (including one with an insulating layer formed), it is cured and cured. An anchor was newly driven into the concrete frame and the finishing material was applied on this anchor.

However, in the work of driving the anchor, it is necessary to mark the surface of the finishing material to be stamped, and it is troublesome to carry out the work twice.

Further, the space maintaining member (bolt member or the like) to be embedded in the concrete in the conventional formwork method is a heat bridge or a bridge member because one bolt member is embedded as it is in the state of penetrating the concrete member. It works as a cool bridge and has a problem of impairing heat insulation performance.

Further, a bolt-integrated type attached to the bolt member used in the conventional formwork method, that is, a holding member with a bolt portion, flattens the concrete surface after pouring concrete without protrusions such as bolt portions. Therefore, it is removed together with a pressing member such as a square bar made of wood or a steel pipe made of metal, which is called vertical flap or horizontal flap. Then, in order to finish the concrete surface flat, the concave portion on the concrete surface where the holding member with the bolt portion is removed is filled with some joint material, which is very troublesome.

As a solution to such a problem,
Applicant is Japanese Patent Application No. 4-21620 (Japanese Patent Laid-Open No. 6-66024)
Has proposed a support tool for concrete wall construction.

The construction of this construction support comprises a pedestal member and a fixing rod-shaped member. The pedestal member has a front surface side insertion hole in its front surface portion and an inner insertion hole in its inner surface portion facing the front surface portion. The pedestal member has a front surface side insertion hole into which the fixing rod-shaped member penetrating the heat insulating material and protruding to the front surface side is inserted, and the inner insertion hole for holding a space embedded in a concrete member. A rod-shaped member is inserted,
Since the space holding member and the fixing rod-shaped member are separated, the external heat insulation performance is improved. Furthermore, the fixing rod-shaped member is used as a support material for the finishing material, and the finishing material is applied without hammering the anchor to the concrete skeleton. It is possible to solve the above problems at once.

By the way, at the time of pouring concrete, impact and tensile force generated at the time of pouring are applied to the rod-shaped member through the form frame. When the impact and the tensile force are applied to the fixing rod-shaped member and the pedestal member having the above-mentioned configuration, the pedestal member has a large load, and there is a danger that the pedestal member made of resin or the like may be destroyed.

Further, the fixing rod-shaped member having an appropriate length must be replaced according to the finish thickness of the finishing material (exterior material). Further, when the fixing rod-shaped member is particularly long, it is already made. There are various problems such as the inability to tighten with Form Tie (registered trademark).

[0010]

The problem to be solved is that the problem of external heat insulation performance and the problem of breakage of the pedestal member cannot be solved at the same time, and the fixing rod member can be constructed as a support material for the finishing material. However, it is a point that the fixing rod-like member must be renewed to have an appropriate length depending on the finished thickness of the finishing material.

[0021]

[Function] Supports used for construction of concrete walls are
Inside the concrete pouring space and the inner end of the fixing rod-shaped member that is formed by the pedestal member that abuts the inner surface of the front-side mold and the fixing rod-shaped member that projects to the outside of the front-side mold Since the space-holding rod-shaped members that are buried in the concrete are directly connected, impact and tensile force during concrete pouring will be applied to both rod-shaped members, so that the pedestal member may be damaged by the external pressure during pouring. There is nothing.

Since the connection between the fixing rod-shaped member and the distance maintaining rod-shaped member can be released by rotating the rotating operation portion of the fixing rod-shaped member, the connection is released after the concrete is poured, and both rod-shaped members are released. It can be separated, has no influence of heat bridge and cool bridge, and has sufficient heat insulation ability.

The problem of heat insulation of the heat bridge and the cool bridge is solved, and moreover, the enlarged diameter portion of the fixing rod member comes into contact with the bottom of the large diameter hole portion, and the fixing rod member does not come out from the pedestal member. Therefore, by using the protruding end portion of the fixing rod-shaped member as the support portion of the finishing material,
Finishing material can be applied without driving an anchor separately, and for this fixing rod-shaped member, the protruding level to the outside of the front side mold can be adjusted freely, so the finishing thickness of the finishing material can be adjusted. You can easily level up according to the level.

The male screw portion of the fixing rod member is screwed into the female screw portion of the pedestal member so that the protruding level of the fixing rod member can be finely adjusted. The protrusion level of the fixing rod member can be finely adjusted.

Since the enlarged diameter portion of the inner end of the fixing rod member is larger than the outer diameter of the front side portion of the pedestal member, the maximum protruding level of the fixing rod member can be restricted. Even if it melts due to fire or the like after casting, the enlarged diameter portion does not come out by coming into contact with the concrete hole portion on the front side portion trace of the pedestal member, and the finishing material can be retained so as not to fall off from the concrete wall.

The pedestal member is divided into a front side portion and an inner side portion, and a front side portion having an appropriate length in the axial direction is detachably provided with respect to the inner side portion.
This can be dealt with by replacing only the front side portion having an appropriate length according to the thickness of the mold.

A protrusion corresponding to the enlarged diameter portion of the fixing rod member is formed in the opening on the inner surface side of the through hole of the pedestal member in such a manner that a fitting fit relationship with the enlarged diameter portion is exhibited. Therefore, the pedestal member and the fixing rod-shaped member loosely restrain the rotation motion of both, and the pedestal member is temporarily fixed so that it will not move due to impact or vibration during concrete pouring, and the pouring space is maintained at a predetermined interval. it can.

Regarding the construction structure of the concrete wall using the above-mentioned support, formwork is arranged on the front side and the back side to form a concrete pouring space, and in the concrete pouring space, a pedestal member is provided on the inner surface of the front side formwork. The front surface part, the rear surface part of the holding member on the inner surface of the backside mold, and the rear surface part of the holding member are arranged in contact with each other, and the interval holding rod-shaped member is arranged between the pedestal member and the holding member. Side end,
Since it penetrates through the pedestal member and is connected to the projecting fixing rod-shaped member on the surface of the front side formwork, the pedestal member is destroyed by the impact and tensile force during concrete pouring, and the concrete pouring space is damaged. It is possible to obtain a predetermined concrete wall without such a thing, and after the concrete is hardened, the fixing rod-shaped member and the distance-holding rod-shaped member are disconnected and separated, so that they have excellent external heat insulation and heat. The effects of bridges and cool bridges are good, not reaching concrete members.

After the concrete is hardened, the fixing rod-shaped member is rotated to release it from the connection state with the space-holding rod-shaped member, and the fixing rod-shaped member is appropriately pulled out to project the tip of the rod-shaped member. Since the finishing material is arranged in the portion, the finished surface of concrete can be finished with finishing materials having various finishing thicknesses only by adjusting the projecting level of the fixing rod member.

Since the protruding end portion of the fixing rod-shaped member is used as a support portion for the finishing material, the finishing material is constructed,
Workability is significantly improved compared to the one using conventional anchors, leading to short-term construction. Moreover, since the fixing rod-shaped member of the finishing material is embedded in the concrete member through the pedestal member, excellent mounting strength can be obtained as compared with the wall structure having a post-cast anchor.

According to claim 5, a protrusion corresponding to the enlarged diameter portion of the fixing rod-shaped member is formed in the opening on the inner surface side of the through hole of the pedestal member in such a manner as to form a fitting fit relationship with the enlarged diameter portion. Therefore, the pedestal member and the fixing rod-like member loosely restrain the rotational movements of both, and the pedestal member is temporarily fixed so that it will not move due to impact or vibration during concrete pouring, and the pouring space is spaced at predetermined intervals. Can be maintained at

G. According to claim 6, since the pedestal member is not destroyed by the impact or the pulling force at the time of placing concrete and the concrete placing space is not damaged, a predetermined concrete wall can be obtained, and
After the concrete is hardened, the fixing rod-shaped member and the space-holding rod-shaped member are disconnected from each other and separated from each other, so that the external heat insulating property is excellent, and the influence of the heat bridge and the cool bridge does not reach the concrete member and is good.

H. According to the same paragraph, after the concrete is hardened, the fixing rod-shaped member is rotated to release it from the connection state with the interval holding rod-shaped member, and the fixing rod-shaped member is appropriately pulled out to the protruding portion at the tip of the rod-shaped member. Since the finishing material is arranged in the finishing material, the finished surface of the concrete can be finished with finishing materials having various finishing thicknesses only by adjusting the projecting level of the fixing rod member.

I. According to the above paragraph, the protruding end portion of the fixing rod-shaped member is used as the support portion of the finishing material to perform the finishing material construction. Leads to construction. Moreover, since the fixing rod-shaped member of the finishing material is embedded in the concrete member through the pedestal member, excellent mounting strength can be obtained as compared with the wall structure having a post-cast anchor.
