Floor slab reinforcement protective layer double-control precast concrete cushion block and installation method thereof

Abstract

The invention relates to a floor slab reinforcement protective layer double-control precast concrete cushion block and an installation method thereof. The protective layer cushion block comprises a pair of upper supporting legs and a pair of lower supporting legs, wherein an upper support notch is arranged between the upper supporting legs, a lower support notch is arranged between the lower supporting legs, one upper supporting leg is short, the other upper supporting leg is long, the vertical height between the top of the long upper supporting leg and the bottom of the lower supporting leg is the thickness of a floor slab, the vertical height between the top of the long upper supporting leg and the top of the short upper supporting leg is the thickness of the upper row of the reinforcement protective layer, and the vertical height between the bottom of the lower supporting leg and the bottom side of the lower row of reinforcement in the lower support notch is the thickness of the lower row of the reinforcement protective layer. Compared with the prior art, the design has the advantages that the thickness of the floor slab, the thickness of the upper row of the reinforcement protective layer and the thickness of the lower row of the reinforcement protective layer can be simultaneously limited, the casting of the floor slab and the floor slab reinforcement protective layer with the corresponding thicknesses can be realized without additional support members, the construction is relatively convenient, the labor intensity and cost are relatively low, the construction efficiency is high, and the quality is relatively reliable.

Description

technical field [0001] The invention relates to the field of construction, and relates to a double-control prefabricated concrete cushion block for a steel bar protection layer of a floor slab and an installation method thereof. Background technique [0002] In the field of engineering construction, it is very important to strictly control the design thickness of the floor slab and the thickness of the protective layer of steel reinforcement on the safety and durability of the structure during the construction of the floor slab structure. Therefore, a construction technology is necessary to effectively control the protection of the two rows of steel bars on the floor slab. Layer thickness and floor design thickness. Traditional construction generally adopts a combined method to control the thickness of the protective layer of steel bars and the thickness of the floor slab, which has common problems such as difficult quality control and inconvenient operation. For example, h...
