Description

Technical Field

[0001] The invention relates to a secondary structure masonry wall, in particular to a masonry template structure of a T-shaped structural column in a masonry wall. Background Art

[0002] In the construction of reinforced concrete frame buildings, when the primary structure is completed, the secondary structure is generally constructed. During the construction of the secondary structure masonry wall, structural columns need to be set in the wall. The main function of the structural column is to tie the masonry wall horizontally to ensure the stability of the masonry wall. The traditional construction sequence is: first reserve a position for the structural column on the floor slab, tie the steel bars in the structural column at this position, and then build the wall outside the structural column. Finally, support the concrete pouring formwork of the structural column by attaching it to the completed masonry wall, and complete the construction of the structural column by pouring concrete, so as to achieve the tie of the structural column to the masonry wall. The structural columns and walls form a stable whole; some secondary structure walls on the floor slab are arranged in a T shape, which requires reserving and constructing T-shaped structural columns to achieve the connection of the T-shaped walls. Due to the limited space here, it is very difficult to support and fix the T-shaped structural column concrete casting formwork here. In order to solve this problem, technicians in the same field have made various attempts; for example: Patent No. 202311229022.0, the patent name is "A formwork-free construction method for masonry wall structural columns" discloses a method for constructing structural columns. The patent invents a formwork-free shell block, which is a formwork-free shell block with the same module as the wall block. The free-formwork blocks are laid around the structural columns, and a U-shaped cavity is set on the free-formwork blocks. The steel bars in the structural columns are set in the U-shaped cavity. The outer side of the structural columns is closed by laying free-formwork blocks, and the closed free-formwork blocks replace the concrete casting templates of the structural columns. Finally, the self-compacting concrete is poured into the cavity closed by the free-formwork blocks, thereby completing the construction of the concrete structural columns of the tie wall. This method of constructing structural columns solves the problem of supporting and fixing the templates of special-shaped structural columns, but there are still the following problems: (1) Since the free-formwork blocks of the same module of the structural column are built into a hollow cavity by mortar, the subsequent concrete pouring of the structural column is difficult to be completed. During concrete pouring, mortar leakage is likely to occur in the masonry mortar joint layer, which is similar to the phenomenon of bulging formwork leakage, affecting the quality and appearance of the structural column; (2) If the height of the structural column reaches more than 2 meters, due to the high pressure of the concrete poured in the column, under the action of this pressure, the same modulus unsupported formwork blocks are likely to shift due to the formwork displacement, resulting in distortion defects in the structural column concrete; (3) Since the same modulus unsupported formwork blocks and the connected masonry walls are connected together through a tooth-shaped overlap, there is a phenomenon of insufficient concrete pouring in the tooth-shaped cavity of the unsupported formwork blocks, resulting in voids at the junction of the structural column and the masonry wall. Summary of the invention

[0003] The invention provides a masonry formwork structure for T-shaped structural columns in a masonry wall, which solves the technical problems of the existing masonry formwork structure that the masonry mortar mortar joint layer is prone to leakage and the formwork-free shell building blocks are prone to formwork displacement.

Therefore, when pouring concrete in the hollow T-shaped closed cage, the left-side and right-side support-free formwork shell blocks can only move backwards due to the squeezing of the concrete. The present invention fixes a left wedge-shaped block on the left rear outer side elevation of the left-side support-free formwork shell block, and fixes a right wedge-shaped block on the right rear outer side elevation of the right-side support-free formwork shell block. A left wedge-shaped block is inserted into a wedge-shaped groove on the right end side elevation of the left wall block, and a right wedge-shaped block is inserted into a wedge-shaped groove on the left end side elevation of the right wall block. The wedge-shaped block is plugged into the wedge-shaped groove and matched with the wedge-shaped groove.
