Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a grid structure for the compartment joint of waffle slabs. Background Technique

[0002] During the construction process of a building, for large-area waffle slabs, it is necessary to carry out compartment flow construction. However, the control of the construction quality at the compartment joints is of utmost importance. The existing methods of enclosing with wooden formwork or grids cannot effectively solve the problems such as slurry leakage, formwork bulging, and excessive surface flatness that are prone to occur at the compartment joints during pouring. Therefore, a reliable grid structure is needed to meet the construction requirements.

[0003] In the prior art, the grid structure for the compartment joint of waffle slabs disclosed in the patent with the publication number CN209163445U includes an upper angle steel, a lower angle steel, grid bars, and a quick-setting closing net. A plurality of grid bars are arranged at intervals and are respectively fixed to the outer surfaces of the upper angle steel and the lower angle steel at both ends, forming a grid framework with a "C" cross-section. The lower edge of the lower angle steel is abutted against the casting bottom formwork, and the upper edge of the upper angle steel is at the elevation of the casting completion surface. The quick-setting closing net is bound to the casting side of the grid bars by binding wires.

[0004] However, for this grid structure in the comparative document, when in use, it is necessary to bind the quick-setting closing net to the grid bars by binding wires. This fixing method requires a large amount of time for tying and wrapping during actual use, which may slow down the construction speed, reduce the construction efficiency, and prolong the construction period.

A screw rod is screwed inside the connecting wire sleeve, and one end of the screw rod is fixed with a stopper, and the stopper blocks on one side of the connecting steel.

[0007] Preferably, both the upper angle steel and the lower angle steel are in an "L"-shaped plate structure, and the upper angle steel and the lower angle steel are symmetrically distributed about the center of the long side of the connecting steel. Screw holes are opened on the surfaces of the upper angle steel, the connecting steel, and the lower angle steel, and both the upper angle steel and the lower angle steel are fixed to the surface of the connecting steel by screws.
