the utility model comprises a supporting block and a supporting block, wherein the supporting block is provided with a bracket groove at the upper end, the bracket groove is composed of an upper bracket groove and a lower bracket groove in a cross shape, the upper bracket groove and the lower bracket groove are communicated with the upper end surface of the supporting block, the lower end of the supporting block is provided with a limit groove, the limit groove is composed of an upper limit groove and a lower limit groove in a cross shape, the upper limit groove and the lower limit groove are communicated with the lower end surface of the supporting block, a cavity is arranged between the upper limit groove and the lower limit groove, and the supporting block is accommodated in the cavity; the upper end of the supporting block is provided with a supporting groove, the supporting groove is composed of an upper layer supporting groove and a lower layer supporting groove in a cross shape, and the upper layer supporting groove and the lower layer supporting groove penetrate through the upper surface of the supporting block.
The supporting block is of a trapezoidal structure.
The upper surface and the lower surface of the supporting block are both square, and the side length of the square on the upper surface is 1/2 of the side length of the square on the lower surface.
The support block is of a cube structure.
And the supporting block are both formed by pouring concrete.
The depths of the upper bracket and the upper support groove are 1/2 of the diameter of the steel bar, and the depths of the lower bracket and the lower support groove are 1/2 of the diameter of the steel bar.
Compared with the prior art, the utility model discloses the beneficial effect who has is:
1. the utility model discloses constitute by tray and supporting shoe, place floor lower floor's reinforcing bar in the tray during use, place the supporting shoe in tray and floor lower floor's reinforcing bar top again, make the tray be located the cavity of supporting shoe, lower floor's reinforcing bar has the support of tray, has guaranteed the protective layer thickness of floor lower floor's reinforcing bar to there is enough thick concrete to live reinforcing bar parcel, does not let reinforcing bar and air contact, avoids the condition such as reinforcing bar oxidation rust or acid gas corrosion.
2. The utility model discloses utilize the good nature of concrete compressive strength, the supporting shoe of application concrete preparation has guaranteed that the upper and lower floor's reinforcing bar of floor can not sink because trample and pile up the heavy object to it is not enough to avoid the upper and lower floor's reinforcing bar interval of floor, guarantees that floor thickness satisfies the designing requirement.
3. The utility model discloses place the supporting shoe in the tray top during the use, the tray is located the cavity of supporting shoe, and simple structure uses and operates also simply, saves the engineering time. It both can provide the supporting role of upper and lower layer reinforcing bar, can guarantee again that the protective layer thickness of upper and lower layer reinforcing bar meets the requirements, the standardization of standard reinforcement that can be better.
