Description

[Detailed Description of the Invention] This invention is a wall-type reinforced concrete! 7-471 This relates to the reinforcing construction method for structures.

Conventionally, when constructing a wall-type reinforced concrete structure using cast-in-place concrete, the M1 side wall reinforcing bars are assembled and arranged at the construction site, which requires considerable time and effort.

Furthermore, reinforcing bars were intersecting at the intersections of the walls (there was a risk of poor filling properties when pouring concrete. In addition, cracks appeared at unspecified locations due to drying shrinkage of the concrete, causing problems with waterproofing and finishing. was occurring.

This invention is a construction method intended to solve all of the above-mentioned problems, and will be explained in detail with reference to the drawings.

For construction, first, the reinforcing steel panel lfI is prefabricated by assembling it in a factory or the like.

This reinforcing bar panel 1 has a size corresponding to the wall surface, that is, a height that is slightly larger than the width of the wall rjJ or span and the floor height or the floor height in the case of upper and lower overlap joints, and the horizontal reinforcement 2
and vertical reinforcements 3 are assembled in a double or single lattice pattern as shown in the figure, and if there are any awkward openings, the reinforcing bars at those locations may be omitted as appropriate.

The above-mentioned reinforcing steel panels 1 are arranged in series, in a cross shape, or in a T-shape at intervals approximately corresponding to the wall thickness. In addition, the main reinforcement 4 of the wall burl is extended at the slab height position to connect the reinforcing bar panels 1 that are in instant contact with each other, and the reinforcing bar panel 1.1 is used as a through bar.
1 connected state.

Next, a formwork (not shown) is arranged around the reinforced panel 1, and concrete 5 is poured. At this time, the drying and cracking of the cast-in-place concrete concentrates in the gap where there is no panel reinforcement, so it is easy to cause cracks to occur, so create a trigger joint 6 here, apply caulking within that purpose, and separate it from the outside wall. By preventing water leakage and determining the locations where cracks occur, waterproofing measures can be easily taken.

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

This invention has the above-mentioned structure, and in wall-type reinforced concrete structures such as apartment complexes, where most of the wall reinforcement is the same, it is possible to save labor by converting this into a broken panel. can.

In addition, in the support gap section, the horizontal reinforcing bars are extended and used as through bars to connect the reinforcing bar panels, making assembly easy. Furthermore, since there are fewer reinforcing bars in the support gap, the concrete fillability is good.

Claims (1)

[Claims] (1) Pre-assemble a reinforcing bar panel with horizontal and vertical reinforcements to a size corresponding to the wall surface, and arrange the reinforcing panels in a straight, cross-shaped or T-shape at intervals approximately corresponding to the wall thickness. The arrangement of the two-wall reinforced concrete structure is characterized in that the wall concrete is placed in the shape of a letter and the adjacent reinforcing panels are connected to each other by through-bars which are extensions of the main bars of the wall frames.
