Straight-section removal-free concrete template wall and bar penetration mounting construction method thereof

Abstract

The invention relates to a straight-section removal-free concrete template wall and a bar penetration mounting construction method thereof and belongs to the technical field of assembly type buildings. The template wall comprises a straight-section removal-free concrete template and also comprises vertical steel bars and transverse steel bars which are arranged in the straight-section removal-freeconcrete template, wherein the straight-section removal-free concrete template comprises concrete slabs arranged on the inner side and the outer side, pull rods which are uniformly distributed between two layers of concrete slabs and pre-embedded lifting parts; the two layers of concrete slabs on the inner side and the outer side are connected together in series through the pull rods; the pre-embedded lifting parts are pre-embedded in the concrete slabs on two sides. The straight-section removal-free concrete template wall has the advantages of the cast-in-place structures, is high in integrality, high in anti-seismic capability and low in possibility of formation of cracks, and also has the advantages of the assembly type buildings; the on-site manpower is economized; the construction site is clean and tidy; the construction period is shortened.

Description

technical field [0001] The invention relates to a straight-section non-demolition-free concrete formwork wall and its installation method for piercing bars, belonging to the technical field of prefabricated buildings. Background technique [0002] In the prefabricated construction industry, there are many deficiencies in related technologies. For example, 1. The prefabricated company has a large weight, high transportation and hoisting costs, and inconvenient operation; 2. Vertical concrete prefabricated components cannot connect the upper and lower layers of steel bars like traditional The same as the cast-in-place technology, the binding connection of vertical steel bars can only be connected by grouting sleeves. However, the quality of grouting sleeves in the market is uneven, and the quality inspection cannot be carried out well, resulting in frequent quality accidents; 3 .Cold joints exist at the interface between new and old concrete. Due to the irreversibility of conc...

Problems solved by technology

[0002] In the prefabricated construction industry, there are many deficiencies in related technologies. For example, 1. The prefabricated company has a large dead weight, high transportation and hoisting costs, and inconvenient operation; The same as the cast-in-place technology, the binding connection of vertical steel bars can only be connected by grouting sleeves. However, the quality of grouting sleeves in the market is uneven, and the quality inspection cannot be carried out well, resulting in frequent quality accidents; 3 .Cold joints exist at the interface between new and old concrete. Due to the irreversibility of concrete, cold joints exist permanently, which greatly reduces the seismic integrity of the building, and cracks are prone to occur in the later stage, resulting in water leakage problems.
