Abstract

(57) [Abstract] [Purpose] When placing fresh concrete on a rising surface with blowout, a pouring method for preventing blowout and stabilizing the finish [Structure] A plate with a large number of holes The holding plate consisting of is temporarily fixed to the coral shown by the code, and by the hose shown by the code, the concrete is poured between the outer formwork and the inner formwork shown by the code, shown by the code, and the rising surface is Construction method

Description

[Detailed description of the device] [Industrial application]

 Suitable for placing upright surfaces when constructing reinforced concrete buildings such as buildings

[Prior art]

 After pouring ready-mixed concrete into the rising surface formwork and pouring the rising surface and then pouring ready-mixed concrete onto the slab surface to finish the iron, at the time of pouring the rising surface, the rising surface with blowing is When pouring fresh concrete to such a height that it will blow out on the surface of the slab due to the weight of the fresh concrete, the pouring of raw concrete was stopped at a certain height, left for several hours, and a certain amount of solidified blowout occurred. When no longer generated, ready-mixed concrete is poured again to complete the rising surface.

[Problems to be solved by the device]

As shown above, since a leaving time is required once during the process, continuous work cannot be performed, resulting in work loss time.

When left on the way once, the upper surface also solidifies to some extent, so that the re-cast concrete and the previously filled portion are not sufficiently joined, and a phenomenon called soaking occurs. Causes insufficient strength, cracks, and water leakage

A method of inserting a vibrator is generally used in order to prevent splicing and deviation of the aggregate, but when vibrating vigorously, blowout occurs again and the vibrator is weak. Can not be solved

[Means for Solving the Problems]

 Temporarily install a holding plate consisting of a plate with a large number of holes on the slab surface of the rising surface that is in contact with the internal formwork.

[Action]

 Prevent blowout of fresh concrete onto the slab surface

[Effect of the device]

The use of a holding plate made of a plate having a large number of holes has a remarkable effect in preventing the aggregate from being caught in the holes and blowing out.

By using a holding plate consisting of a plate with a large number of holes, the inside can be seen and the filling state at the bottom of the rising surface can be confirmed, thus stabilizing the quality

By using a holding plate made of a plate having a large number of holes, water is easily separated and solid stability is fast.

Since blowout can be prevented, pouring to the rising surface can be continued up to the top, so no splicing occurs

Overall work time can be shortened by continuous construction and early stabilization.

The same effect is exerted not only on the wall surface but also when stairs are cast.
