Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reinforcing construction method for wall-type reinforced concrete structures.

Conventionally, when constructing a double-wall reinforced concrete structure using cast-in-place concrete, vertical and horizontal wall reinforcing bars are assembled and arranged at the construction site, which requires considerable time and effort.

Furthermore, the reinforcing bars intersect at the intersections of the walls, which may result in poor filling performance when pouring concrete.

In addition, cracks appeared in unspecified locations due to drying shrinkage of the concrete, causing problems with waterproofing and finishing.

This invention is a construction method intended to solve the above-mentioned problems, and its details will be explained with reference to illustrated embodiments.

During construction, the reinforcement panel 1 is first assembled and organized in a factory or the like to form a pre-knobs.

This reinforcing bar panel 1 has a size corresponding to the wall surface, that is, the width of the wall or span, and a height slightly larger than the story height or the story height when the top and bottom are overlapped, and has horizontal reinforcements 2 and vertical reinforcements 3. As shown in the figure, it is assembled in a double or single grid pattern.

If there is an opening, the reinforcing bars in that area should be omitted as appropriate.

The reinforcing steel panels 1 described above are arranged in a series, a cross, or a T-shape at intervals approximately corresponding to the wall thickness.

Further, large diameter reinforcing bars 4 in the shape of a rod, cross or T are inserted as horizontal tethers between adjacent reinforcing bars 1 at the slab height to bring the reinforcing bars 1.1 into a connected state.

Next, a formwork (not shown) is arranged around the reinforced panel 1, and concrete 5 is poured.

In this case, at intersections where there is no panel reinforcement, drying of cast-in-place concrete tends to concentrate and cause cracking, so crack-inducing joints 6 are provided here and caulking is applied within the joints to prevent water from leaking from the outer wall. By preventing cracks and determining the locations where cracks occur, waterproofing measures can be easily taken.

In addition, the vertical joints of the reinforcing steel panels 1 on the upper and lower floors are made outside of lap joints.
Join by gas pressure welding or mechanical joints.

The present invention has the above configuration, and since most of the wall reinforcements are the same in a wall-type reinforced concrete structure such as an apartment complex, it is possible to save labor by converting it into a prefabricated panel.

In addition, at wall intersections, large-diameter reinforcing bars that provide sufficient connection strength are inserted only at the slab height, and horizontal reinforcing bars do not intersect, making it easy to erect reinforcing panels.

Furthermore, since there are fewer reinforcing bars at wall intersections, the concrete fillability is good.

Claims (1)

[Claims] 1 Construct a reinforcing panel that is pre-assembled into a lattice shape with double reinforcement with horizontal and vertical reinforcements to a size corresponding to the wall surface, and the reinforcing panels are separated at intervals approximately equivalent to the thickness of the wall. At the same time, large-diameter reinforcing bars are arranged in series, cross, or T-shape at the same time, and are connected by inserting large-diameter reinforcing bars in bar-shape, cross-shape, or T-shape only between adjacent reinforcing bars at the slab height. A reinforcing construction method for a reinforced concrete structure on the second wall, which is characterized in that the wall concrete is cast as a condition.
