CONSTITUTION: A counterbored recessed part 3 is installed on the bottom of each bolt hole 1 on a hard rubber board 2 which bores the bolt hole 1 in conformity with a connection bolt hole 26 on the flange board 24 installed on the lower end of a support main body 32 while a headless bolt 6, whose lower end forms a projected end 5, is inserted into each bolt hole 1 and the projected end 5 is buried in and covered with a soft foam rubber board 7. Prior to concrete support work, each projected part 5 is projected from the compressed rubber board 7 by means of the flange board of the pipe support expanded vertically between the ceiling form and the floor surface so that each of the projected part may be projected from the rubber board 7 and fitted into the ceiling form and the floor surface respectively. A rubber board 2 helps the projected end bite in and cover some deviations and prevents the pipe support from falling from a sliding movement.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stabilizer for preventing a support pipe from sliding on a concrete shoring at a reinforced concrete building site.

[0002]

2. Description of the Related Art In a reinforced concrete building site, when a supporting work for supporting a ceiling formwork for concrete casting from a floor is carried out, conventionally, as shown in FIG.
A so-called pipe support 22 which can be adjusted up and down by 1 is used, and flanges 23 and 24 serving as support surfaces are fixed to upper and lower ends of the pipe support 22, and two nails for fixing are respectively provided on the flanges 23 and 24. A hole 25 and four bolt holes 26 for joint bolts are generally drilled.

[0003] In the support work, a flange plate 23 at the upper end is applied to the lower side of a formwork 27 constructed on the ceiling via a sleeper 28 and a flange plate 24 at the lower end via a floor plate 29 on a floor surface. After adjusting the contact and vertical extension, nail the nails into the nail holes 25 to fix the upper and lower sides, and in order to prevent the sliding movement and ensure the stable standing, place the pipe 30 in the horizontal cross direction near the upper and lower ends above a certain height to ensure a stable standing. It is obligatory to take the so-called root rust which is passed and fixed to prevent lateral movement.

[0004]

According to a conventional construction method, the upper and lower adjustable flanges of the pipe support are nailed and fixed to the support of the ceiling formwork to fix the ceiling form, and further, the root scum is removed. Although the upper and lower support parts are surely prevented from sliding,
Since there are hundreds of pipe supports on each floor, it takes a lot of time to nail, especially nail nails on the upper end for climbing a stepladder and hitting sleepers in a dark indoor work site. In addition to the danger, if the upper and lower cruciform root debris removal work and the removal work after use are combined, the labor and time cost becomes enormous. While the collar plate is used many times, shocks during transportation are repeated, and it is not easy to work while correcting the edge of the collar plate.

Further, the interval between the forested pipe supports is narrower as the concrete load is larger, and fixing the pipes in this direction in the cross direction and removing the root mess hinders walking, and it is difficult for the worker to move and the footing is bad. There were problems such as danger and poor workability. SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and prevent the support main body from sliding without requiring nailing or root fining, and stably support the main body.

[0006]

SUMMARY OF THE INVENTION The present invention is to be used by being attached to a conventionally used pipe support, and to be fitted to four connecting bolt holes of a flange plate provided at the upper and lower ends of the pipe support. A counterbore recess is provided on the lower surface of each bolt hole of a square hard rubber plate having an appropriate thickness by drilling four bolt holes, and each bolt hole is fitted into the counterbore recess. Insert a headless bolt with a pierced end at the lower end that has a flange and protrude from the hard rubber plate, pierce the pierced end of the headless bolt with a flexible foam rubber plate attached to the lower surface of the hard rubber plate, and It is configured to project into the bolt hole of the flange plate of the overlapped pipe support and screw it with a tightening nut,
The piercing ends of each headless bolt are projected from the compressed rubber foam plate by the flange plate of the pipe support which is stretched up and down between the ceiling frame plate and the floor surface during the support work, and the ceiling form and the floor surface It is characterized by preventing the pipe support from sliding and falling down by piercing each other.

In the second aspect of the present invention, a square hard rubber plate is provided with bolt holes at four corners, and the lower peripheral edge of the square is cut into a piercing box having an open lower surface as a cutting blade, and a foamed rubber plate is laminated by the thickness of the cutting blade. When the pipe support is extended by attaching the top surface of the piercing box to the upper and lower collar plates of the pipe support and sticking the top surface of the piercing box, pierce the ceiling formwork and the floor surface with four cutting blades protruding from the foam rubber plate. It is characterized by being bitten to prevent slippage.

[0008]

The present invention is constructed using the conventional pipe support as it is, and the top of the headless bolt held by the hard rubber plate in the connecting bolt holes of the upper and lower collar plates of the conventional pipe support. Of the counterbore and the nuts are fixed by tightening the nuts, but the flange of the counterbore recess receives the force of the nuts that screw into the upper part of the bolt, and the hard rubber plate is closely attached to the flange plate while adding its elasticity. Since the piercing end of the headless bolt projecting from the lower surface of the rubber plate is covered and protected by the flexible foam rubber plate, the worker is not injured during work or transportation.

In supporting the formwork, the pipe support is extended between the formwork and the floor surface, and when the flange plate is pressed against the formwork and the floor surface, the piercing end of the headless bolt is pressed to reduce the thickness of the foam. It penetrates through the rubber plate and bites into the upper formwork and the lower floor, respectively, so that the formwork is firmly supported and fixed and does not fall. The hard rubber plate helps bite the piercing end with its elasticity,
It can cope with a slight inclination of the pipe support. Further, even if the flange plate is slightly bent by repeated use, the hard rubber plate is fixed correspondingly. Therefore, there is no need to nail the flange plate as in the conventional case, and there is no need to remove the so-called root lashes that fix the upper and lower parts in the cross direction. Is done.

In the second invention, in which the piercing end is the cutting blade at the lower end of the four circumferences of the piercing box, the penetration of the piercing is wide, the fixing action is large, the support fixing is more reliable, and the work safety is further secured.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In general, in reinforced concrete construction work, the number of pipe supports for supporting the ceiling and floor formwork of each floor is a considerable number of hundreds per floor in order to withstand the load at the time of concrete casting. At the same time, there is a danger of falling due to the sliding of the supporting part, so that it takes a lot of time and effort to nail the upper and lower collar plates and to remove root scum to prevent the falling. Since pipe supports are repeatedly carried in at each site and used repeatedly, there are thousands of stocks.

The present invention is a safety device for a pipe support which eliminates nailing of upper and lower collar plates and removal of root debris, and the first invention uses a remarkably large number of pipe supports that have been conventionally used. As shown in FIG. 1, in the pipe support 22 in which the upper column tube 31 with the lower part inserted is pushed up by the screw socket 34 screwed to the screw 33 on the upper outer periphery of the support body 32 and can be extended vertically, Of a square hard rubber plate 2 having a proper thickness by drilling bolt holes 1 matching the four bolt holes 26 for connecting the collar plates 23, 24 provided at the upper end of the support body 32 and the lower end of the support body 32. , A counterbore recess 3 is provided on the lower surface of each bolt hole 1, and each bolt hole 1 has a collar 4 that fits into the counterbore recess 3 and the lower end protruding from the hard rubber plate 2 is a piercing end 5. Insert the headless bolt 6 The end 5 is buried with a flexible foam rubber plate 7 laminated on the lower surface of the hard rubber plate 2 to prevent the risk of injury from the piercing end 5, and the upper end of the headless bolt is a pipe superposed on the hard rubber plate. Bolt hole 26 of support collar plate 24
The flanges 23 and 2 of the pipe support are formed by projecting upward and screwing them with the tightening nuts 8 and extending vertically between the ceiling formwork and the floor surface in the concrete supporting work.
At 4, each piercing end 5 of the headless bolt is projected from the foamed rubber plate 7 to be pierced into the ceiling formwork and the floor surface, respectively, so that the hard rubber plate 2 assists the biting and covers a slight displacement. This reliably prevents the pipe support from falling down due to slippage.

In the second invention, as shown in FIG. 2, a square hard rubber plate 9 is provided with stud bolts 10 at the four corners of the upper surface, the lower surface is opened, and the lower edge of the four weeks is a cutting blade 11.
2, and the flexible foam rubber plate 13 is laminated to the thickness of the protruding length of the cutting blade 11 to prevent the risk of injury due to the exposure of the cutting blade 11 and to be screwed to the collar plate. When the pipe support is extended, the cutting blade 11 having a large biting portion bites into the mold frame and the floor surface in a wide range to ensure the prevention of sliding.

When a new pipe support is manufactured, as shown in FIG. 3, by replacing the flange plate portion with the piercing box 12 and directly fixing it to the pipe, the same operation can be performed without the need for mounting the pipe support in use.

[0015]

According to the present invention, the upper and lower flange plates of the pipe support are fixed to the formwork and the floor with the piercing end of the headless bolt or the piercing box of the piercing box in the support of the ceiling formwork for concrete casting. Because it is to be bitten, the fixation is strong and stable without slippage, and the work can be remarkably reduced without the need for any labor and time such as nailing up and down and removing root lumps as usual There is an effect that the user is free to move on the floor and work easily and safely.
