Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fixed setter used for installing piping equipment such as piping sleeves and water supply and drainage hardware during concrete pouring work after temporary framing.

[Conventional technology]

Conventionally, in the construction of steel frames and reinforced concrete buildings, temporary frame panels are constructed, reinforcing bars are placed along the surface of the temporary frame panels, and piping equipment such as sleeves are installed for piping and electrical wiring. Usually, concrete pouring work is carried out.

Sleeves for piping are essential when pipe piping penetrates the floor, ceiling, and walls of a building after concrete is poured.The sleeve is used to isolate the inside from the concrete and use the space after pouring as a hole for the pipe to pass through. are doing.

To install this sleeve, use a rod that is equipped with a centering plate at the lower end and a plate (holding plate) that closes the upper end opening of the sleeve, etc. above the centering plate, and temporarily holds the centering plate. After nailing into the frame panel and closing the upper end opening of the sleeve etc. with the above-mentioned plate (holding plate), it is installed by pouring concrete (Special Publication No. 59-49990
(see publication).

[Problem that the idea aims to solve]

However, in the case of embedding construction as described above, there are the following problems. In other words, when the holding plate is tightened with a nut to close the upper end opening of the sleeve etc., since the rod and centering plate are integrated, the nails nailed to the temporary frame panel will come out. It is easy to become unstable.

Since the holding plate is a flat plate, the edges will lift up when tightening, causing problems when pouring concrete.
Concrete easily enters the sleeve,
Furthermore, the concrete is more likely to be twisted during concrete placement.

Nailing work is required to attach the centering board to the temporary frame panel.

There are other problems.

The present invention was devised in response to the above-mentioned problems, and its purpose is to place piping equipment such as piping sleeves and water supply/drainage fittings in their designated positions without damaging the temporary frame panels. The object of the present invention is to provide a fixing setter that can be securely fixed to the concrete, prevent concrete from flowing into the setter, and is easy to handle.

[Means for solving problems]

In order to achieve the above object, the fixed setter for concrete pouring work of the present invention is a fixed setter for concrete pouring work for installing piping equipment such as piping sleeves and water supply and drainage hardware, and is a fixed setter for concrete pouring work that is used for temporary frame panels. A rod having a coach screw formed at its lower end and having a male screw on its upper side, and a rod which is integrated with the rod above the coach screw and whose lower surface abuts against the temporary frame panel coincides with the axis of the rod. A stabilizer that intersects at right angles, a cover that closes the upper end opening of the piping equipment that is attached to a rod above the stabilizer so that it can be raised and lowered, and a cover fixing device that is screwed onto the male screw of the rod above the cover and holds the cover. The cover has a step at its edge that is lower than the center of the cover, and the step portion comes into contact with the end of the piping equipment.

[Effect]

The fixing setter of the present invention based on the above structure has piping equipment such as a piping sleeve and drainage trap placed on a temporary frame panel, and then penetrates through the piping equipment and is formed at the lower end of the rod. The locking tool is actuated by a rod to lock it to the surface of the temporary frame panel, and a cover having a step lower than the center of the cover at the edge is lowered, and the cover is attached to the top surface of the piping equipment using the cover fixing tool. After the stepped portion is abutted and fixed, concrete is placed on the outside of the piping equipment. Next, after the concrete has cured, the cover is moved up and the rod is operated to remove the coach screw from the temporary frame panel, so that the piping equipment can be installed simultaneously with the concrete work.

As described above, the setter of the present invention has a coach screw at the lower end of the rod, so it can be easily installed on the temporary frame panel without the need for nailing work, and the setter can be easily installed on the temporary frame panel without the need for nailing. By making contact with the equipment at the stepped part formed at the edge of the cover that is lower than the center of the cover, its strength is increased and gaps can occur between the cover and piping equipment. It acts to reduce the amount of water and prevent the inflow of concrete.

Here, FIG. 1 is a perspective view showing an embodiment of the present invention, and FIGS. 2 and 3 are sectional views showing the construction state.

The fixed setter of this embodiment is roughly composed of a rod 10 and a cover 11.

The rod 10 has a locking tool 13 with an acute angle at its lower end 12, and a screwing handle 16 at its upper end 14 for screwing the locking tool 13 into a temporary frame panel 15. Here, the locking tool 13 is formed of a coach screw.

Further, a male screw 17 is formed from the approximate center of the rod 10 to the lower part of the screw handle 16, and a cover fixture 18 is screwed into the male screw 17.
A hollow hemispherical stabilizer 19 is installed above the locking tool 13 in a direction perpendicular to the panel surface of the temporary frame panel 15. Here,
The stabilizer 19 is used to prevent the locking tool 13 from being screwed into the temporary frame panel 15 more than necessary and to restrict the screwing of the rod 10 and to restrict the horizontal shaking of the rod 10, so it is limited to a hollow hemispherical shape. There's no need to be.

The cover 11 has a shape (disk) that matches the size of the sleeve 20 placed on the temporary frame panel 15 and the upper opening 21 of the drain trap 22, and has a hole in the center for the rod 10 to pass through. , Rod 1
It is disposed between the cover fixing tool 18 of No. 0 and the locking tool 13 so as to be movable up and down. The cover 11 is raised and lowered to open the upper opening 2 of the piping equipment (hereinafter referred to as sleeve) such as the sleeve 20 and the drain trap 22.
1, the cover fixture 18 is used to tighten the cover. Here, the cover 11 is used to prevent concrete from flowing in and to prevent the sleeves such as the sleeve 20 and the drain trap 22 from tilting.

Further, a step is formed at the edge of the cover 11 to reinforce the cover itself and to prevent it from turning over during concrete pouring. The size of the cover 11 varies depending on the piping equipment to be installed, and the cover 11 may have a larger shape than the upper opening 21 of the sleeve, if necessary. Furthermore, the cover 11 and the cover fixture 18 may have an integrated structure.

Next, the function of the fixing setter of this embodiment will be explained based on FIG. 2 showing the construction state of the fixing setter of this embodiment.

FIG. 2 shows a case where a sleeve 20 is installed as piping equipment. In FIG. 2, the sleeve 20 is placed on the upper surface of the temporary panel 15 for centering, and the locking tool 13 of the rod 10 is screwed onto the center. Screw in until it reaches the end.
Thereby, the rod 10 is set coaxially with the sleeve 20.

Next, the cover 11 is lowered along the rod 10 and comes into contact with the upper surface of the sleeve 20, and the cover fixture 18 is lowered onto the cover 11 by being screwed into the male screw 17 of the rod 10, and the cover 10 is lowered onto the sleeve 20. Tighten the top surface and the cover fixture 18. Then, the cover 11 closes the upper opening of the sleeve 20 and acts to stably fix the sleeve 20 on the temporary frame panel 15 without using nails or the like.

Subsequently, when concrete is placed on the outside of the sleeve 20, the concrete does not flow into the sleeve 20, and the sleeve 20 is held without shifting from its installed position. Next, after the concrete has cured, screw handle 1
By actuating 6, the locking tool 1 of the rod 10 is
3 is disengaged from the temporary frame panel 15, the rod 10 is taken out from the sleeve 20, and the installation work of the sleeve 20 is completed.

The one shown in FIG. 3 is the same as in FIG. 2 except that a drainage trap 22 is installed instead of the sleeve. This also works in the same way as the previous embodiment.

In the present embodiment described above, the coach screw 13 as a locking tool for locking the temporary frame panel 15 was formed integrally with the lower end 11 of the rod 10. 1
3 differs in shape depending on the material and thickness of the temporary frame panel 15, and in order to cope with this, the shape may be arbitrarily exchangeable. Further, the rod 10 may have a structure in which its length can be adjusted (by adding parts, etc.), or a structure in which the tip end is flared toward the end.

It should be noted that the present invention is not limited to the embodiments described above, and it is clear that various modifications can be made without changing the gist of the present invention.

[Effect of idea]

As is clear from the above description, according to the fixed setter of the present invention, by providing a coach screw at the lower end of the rod, it can be easily installed on a temporary frame panel without requiring nailing work. In addition, since the cover and the piping equipment come into contact with each other at the stepped part formed at the edge of the cover that is lower than the center of the cover, its strength is increased, and the cover and the piping equipment come into contact with each other. This has the effect of reducing the occurrence of gaps between the concrete and the concrete and preventing the inflow of concrete.

In addition, unlike conventional construction methods, there is no need to fix various piping equipment such as sleeves and the temporary frame panel board with nails, wires, etc., so there is less damage to the temporary frame panel, and the temporary frame panel can be used multiple times. It has the effect that it can be used for.

Therefore, according to the present invention, it is possible to simultaneously fix piping equipment such as sleeves and close the upper end opening on the surface of the temporary frame panel, and it is not necessary to use nails, wires, etc., so the construction time is shortened. This has the effect of providing a fixed setter for concrete pouring work that can achieve
