Description

[Detailed description of the invention] ``Purpose of the invention'' (Field of industrial application) The present invention is designed to provide a frame for forming slits in the wall when pouring a wall such as a waist wall in a concrete structure. This invention relates to a support member for supporting a slit forming member disposed therebetween.

(Prior art) Conventionally, in concrete structures where columns and walls such as waist walls are integrally connected, the columns become short columns for each floor, and during earthquakes and other vibrations, the columns are It is known that the shaking effect and twisting effect are reduced and destruction occurs.

Therefore, as shown in FIG. 3, when pouring a wall 22 such as a waist wall, a slit forming member 23 is placed inside the wall near the column 21 to insulate the column 21 and the wall 22. However, a construction method is adopted in which the pillars 21 are made long so as to absorb vibrations and penetrate through each floor. This slit forming member 23 is made of a synthetic resin sponge body, etc., and both ends are supported by slit joint members 26 fixed to the frame 24 with resin nails 25. When pouring concrete, this slit forming member 23 may be pressed and may come off or become biased.

In order to prevent this, conventionally, the frame 24,
A second separator 28 is placed on the side of the slit forming member 23 in addition to the separator 27 placed to set the spacing between the slits 24, and a reinforcing bar 29 is fixed thereto. I was trying to support 23. Further, although the ideal position of the separator 27 is at position A in the figure, it was sometimes moved to position B and a reinforcing bar was fixed thereto.

(Problems to be solved by the invention) However, the conventional means described above requires a second separator, which requires a lot of man-hours to arrange. The work was extremely troublesome because square pipes and the like were concentrated near the pillar (position B).

The purpose of this invention is to eliminate the above-mentioned conventional drawbacks,
To provide a support material for a wall slit forming member that can accurately support a slit forming member 22 by using a separator that should be placed at a normal, preferred position.

"Structure of the invention" (Means for solving the problems) The supporting material of the member for forming wall slits according to the invention is used to form vertical slits in the wall when pouring walls such as waist walls of concrete structures. A supporting member for supporting a slit forming member disposed between the frames so that a slit forming member is formed, and an engaging portion that can be fitted and locked to a separator to be passed between the frames. , a rod-shaped body extending from the engaging portion toward the slit-forming member; a contact portion provided at the tip of the rod-shaped body and abutting the slit-forming member from the lateral direction; It consists of a nail member that protrudes from the front side and is inserted into the slit forming member.

(Function) By inserting the nail member on the front side of the contact part into the slit forming member, the contact part is brought into contact with the member, and the engaging part at the rear end of the rod is inserted between the frames at the normal position. The slit-forming member is accurately supported by fitting and locking the separator that is being passed over the separator.

(Example) An example of the support material for the wall slit forming member according to the present invention will be described based on FIGS. 1 and 2. In the figures, 1 is a column in a concrete structure, 2 is a waist wall. 3 is a slit forming member placed between frames 4 and 4 so that a vertical slit is formed in the wall when the wall is cast, and is made of a synthetic resin sponge body. ing. 5
6 indicates the frame 4, a separator placed between the frames 4 at an ideal position, and 6 indicates the entire supporting material for supporting the slit forming member 3, so that it can be fitted and locked to the separator 5. a rod-shaped body 8 extending from the engaging portion 7 toward the slit-forming member; and a rod-shaped body 8 provided at the tip of the rod-shaped body 8 and extending from the lateral direction with respect to the slit-forming member 3. It consists of an abutting part 9 that abuts, and a nail member 10 that protrudes from the front side of the abutting part 9 and is inserted into the slit forming member 3.

The rod-shaped body 8 is a round bar, and the engaging part 7 is welded to the rear end, and the engaging part 7 has a fitting part 7a into which the round bar-shaped separator 5 is fitted, The lower part has an opening 7b. The abutment part 9 is a rectangular iron plate, and is welded to the tip side of the rod-shaped body 8 so as to be vertically elongated. This contact part 9
It can be reinforced, for example, by forming bent pieces 9a on both ends of the plate or by forming a rib in the middle, thereby making it possible to use a thin material. In the embodiment, only one nail member 10 is projected from the center of the tip of the rod-shaped body 8, but it goes without saying that a plurality of nail members 10 may be provided. In addition, the engaging portion 7
It is also possible to adopt a configuration in which the distance between the rod-shaped body 8 and the contact part 9 can be arbitrarily adjusted.For example, a thread is cut on the tip side of the rod-shaped body 8, and a threaded cylinder is welded to the back side of the contact part 9. The tip of the rod-like body 8 may be screwed into this, or a thread may be cut on the rear end side of the rod-like body 8 and the engaging portion 7 may be screwed through the screw.

In use, the nail member 10 on the front side of the abutment part 9
is inserted into the slit forming member 3 to make the abutting part vertically elongated and abut against the member, and the engaging part 7 at the rear end of the rod-like body is spanned between the frames 4 in a normal position. By fitting and locking into the separator 5, the slit forming member is supported. If the wall thickness is large and the slit forming member 3 is long, two supporting members 6 can be used in parallel to support it.

In FIG. 2, reference numeral 11 is a slit joint member fixed to the frame 4 with resin nails 12, and both ends of the slit forming member 3 are supported by this joint member.

"Effect of the invention" According to the supporting material for the wall slit forming member according to the present invention, by inserting the nail member on the front side of the abutting part into the slit forming member, the abutting part is brought into contact with the member, The slit forming member can be accurately supported by fitting and locking the engaging portion at the rear end of the rod-like body to the separator that is placed between the frames at a normal position.

Therefore, it is not necessary to use a plurality of separators or to move and set the separators as in the past, and it is possible to improve the efficiency of the work.
