Description

Floor reinforcing bar protective layer supports for construction

Technical Field

The utility model relates to a construction technical field, in particular to floor steel bar protection layer supports for construction.

Background

In the engineering construction field, when the floor slab structure is constructed, the influence of the design thickness of the floor slab and the thickness of a steel bar protection layer on the safety and the durability of the structure is very important, so that a construction technology is needed to effectively control the thickness of the protection layer of two rows of steel bars of the floor slab and the design thickness of the floor slab. The traditional construction generally adopts a combined method to control the thickness of a protective layer of a steel bar and the thickness of a floor slab, and has the common problems of high quality control difficulty, inconvenient operation and the like. For example, the upper row of reinforcing steel bars of the floor slab adopts a split heads with the shapes of 'A', 'H', 'I' and the like to support gluten, the lower row of reinforcing steel bars adopts plastic cushion blocks, cement small blocks and the like as protective layer cushion blocks, the thickness of the floor slab is controlled by methods such as 'instrument control method' and 'reinforcing steel bar insertion method', and the methods have the following defects: 1. the traditional split heads have multiple specifications and are complicated and irregular in actual installation; 2. the on-site manufacturing and processing consumes time and labor; 3. the material has poor stability and is easy to crack and collapse after being stressed; 4. the deviation of the actual size of the cushion block manufactured manually is large; 5. the construction cost is high, and the green construction does not reach the standard; 6. the construction quality is difficult to control; 7. the difficulty of combined operation management is large. Therefore, the existing reinforcing steel bar protection layer cushion block needs to be improved.

The utility model discloses a patent CN 204826427U discloses two accuse precast concrete cushion of floor reinforcing bar protective layer, this protective layer cushion is including being used for supporting the last support notch of the row's of floor upper reinforcing bar to and be used for supporting the lower support notch of the row's of floor lower reinforcing bar, and its structural feature lies in protective layer cushion includes a pair of upper strut foot and a pair of lower supporting legs, goes up and is equipped with between the strut foot go up the support notch, be equipped with between the lower strut foot the lower support notch, wherein two upper strut feet are one short and one long, and the vertical height between long upper strut foot top to the lower strut foot bottom is floor thickness, and the vertical height between long upper strut foot top to short upper strut top is row's of reinforcing bar protective layer thickness, and the lower strut foot bottom extremely the vertical height between the lower row's of reinforcing bar bottom side is lower row of reinforcing bar protective layer thickness in the lower support, And the thickness of the upper row of steel bar protection layers and the thickness of the lower row of steel bar protection layers are limited. However, in the utility model, the support of the lower row of steel bars needs an additional embedded cushion block for auxiliary support, and the embedded cushion block is easy to move out from the bottom end of the lower support notch; moreover, after the reinforcing steel bars are inserted, the upper and lower rows of reinforcing steel bars can easily move or shake from the corresponding supporting notches, so that the built reinforcing steel bar system becomes disordered, and the reinforcing steel bars can easily fall off after the formwork is closed, and the phenomenon of exposed reinforcing steel bars after concrete pouring and formwork removal is caused.

Patent CN 206829505U discloses a novel concrete precast cushion block, which comprises a pair of upper supporting feet and a lower supporting seat fixedly connected below the upper supporting feet, wherein an inwards concave waterproof ring is arranged at the waist part between the upper supporting feet and the lower supporting seat, an upper supporting notch for supporting the upper row of reinforcing steel bars on the floor slab is arranged between the upper supporting feet, a lower supporting notch for supporting the lower row of reinforcing steel bars on the floor slab is transversely arranged on one side surface of the lower supporting seat corresponding to the lower part of the upper supporting notch, and the upper row of reinforcing steel bars and the lower row of reinforcing steel bars are parallel to each other and are positioned on; barbs I are symmetrically arranged in the upper support notch, and the front ends of the barbs I are fixed on the inner wall of the upper support notch; the symmetry is equipped with barb II in the lower support notch, and barb II's front end is fixed on the inner wall of lower support notch. Although the unidirectional inlet formed by the barbs in the patent can prevent the reinforcing steel bars from sliding out after sliding in, the reinforcing steel bars cannot easily displace after being bound, the reinforcing steel bars can still slide out, and the tips of the unidirectional inlet can damage the reinforcing steel bars. When putting into the lower support notch at the reinforcing bar, when having hard inhomogeneous, difficult once only putting into the reinforcing bar, the waste time, exactly again, when carrying out the vibration after the concreting, the reinforcing bar takes place the offset back, can not independently return, needs the manual work to adjust the return, and it is hard to take trouble, influences construction period.
