Embodiment Construction

[0022] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0023] A reinforced concrete wall structure for preventing cracking. The reinforced concrete wall is a vertical cantilever structure, and double rows of steel mesh sheets 5 are arranged inside.

[0024] When the wall is a vertical cantilever structure and only connected to the beam 1, set a hidden beam 2 on the top of the wall, and install the hidden beams at a distance of 1.5m to 2.5m along the vertical direction, and at a distance of 3.0m to 5.0m along the vertical direction Set dark column 4. When the top of the wall is in contact with the slab, there is no need to install concealed beams 2 on the top of the wall, only concealed beams 3 are installed at intervals of 1.5m to 2.5m along the vertical direction, and concealed columns 4 are ar...

Abstract

Disclosed is a crack preventing reinforced concrete wall structure. A reinforced concrete wall is of a vertical cantilever structure. Double rows of reinforcement net pieces are configured in the reinforced concrete wall. The lower end of the wall is connected with a foundation. The upper end of the wall is connected with a plate or a beam. When the wall is of the vertical cantilever structure and is only connected with the beam, a streak of concealed beams is arranged on the top of the wall, and the concealed beams are arranged in the vertical direction with the spacing being 1.5 m-2.5 m, and concealed columns are arranged in the longitudinal direction with the spacing being 3.0 m-5.0 m. When the top of the wall is connected with the plate, the concealed beams do not need to be arranged on the top of the wall, the concealed beams are only arranged in the vertical direction with the spacing being 1.5 m-2.5 m, and the concealed columns are arranged in the longitudinal direction with the spacing being 3.0 m-5.0 m. The structure and a construction method thereof are easy and feasible, the probability of occurrence of cracks of the reinforced concrete wall can be effectively reduced, and safety and normal using of the reinforced concrete wall structure are guaranteed.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to a reinforced concrete wall structure for preventing cracking and a construction method thereof. Background technique [0002] During the construction process, cracks in cast-in-place reinforced concrete walls are common, especially in underground engineering exterior walls, and the cracks are often vertical cracks distributed evenly along the length of the wall. Therefore, phenomena such as leakage and steel bar corrosion are often caused, thereby reducing the performance of the structure under long-term use, and seriously affecting the function of use. [0003] The reason for the cracking of the reinforced concrete wall is mainly the result of external force besides the lack of concrete material itself. The external force is mainly temperature stress and external visible force (such as impact, side pressure, etc.) that exceed its bearing capacity. At present,...
