Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring construction, in particular to a control structure of a reinforced concrete protective layer. Background Art

[0002] Concrete cover refers to the concrete layer between the outer edge of the outermost steel bar and the concrete surface in the concrete structure, referred to as the cover. The concrete cover can ensure that the steel bar and the surrounding concrete can work together, and make the steel bar fully exert the strength required by the calculation, and prevent the steel bar from rusting, so as to ensure that the steel bar will not rust to reduce the structural reliability within the design service life.

[0003] When pouring concrete, it is necessary to ensure the thickness of the concrete outside the steel bar to form a concrete protective layer to prevent the formwork from sticking to the steel cage and exposing the steel bars. The traditional solution is to put a pad between the steel cage and the formwork, but the pad is easy to fall off and cannot ensure the thickness of the concrete, which can easily cause the thickness of the steel bar concrete protective layer to be insufficient. Utility Model Content

[0004] The purpose of the utility model is to provide a control structure for the reinforced concrete protective layer in view of the fact that the traditional solution in the background technology is to place a pad between the steel cage and the formwork, but the pad is easy to fall off, cannot effectively ensure the concrete thickness, and easily causes the problem of insufficient thickness of the reinforced concrete protective layer.

The adjusting screw is arranged on the pad, and the snap device is threadedly connected to the adjusting screw. The snap device includes two elastic clamping plates arranged opposite to each other. The elastic clamping plates are located on the side of the snap device away from the pad. The two elastic clamping plates arranged opposite to each other are used to clamp the steel bars. When in use, the snap device clamps the steel bars through the elastic clamping plates, and then the pad is pressed against the formwork. The pad is used to position the formwork, and the steel bars are clamped through the elastic clamping plates, so that the control structure of the present application is not easy to fall off during concrete pouring, thereby ensuring the thickness of the poured concrete protective layer. Furthermore, since the snap device is threadedly connected to the adjusting screw, the position of the snap device on the adjusting screw can be adjusted, and then the interval between the snap device and the pad can be adjusted, so as to adjust the interval between the steel cage and the formwork to adjust the thickness of the concrete protective layer to ensure that the construction requirements are met.

[0009] Preferably, the adjusting screw is located between the two elastic clamping sheets;

[0010] The two elastic clamping pieces are symmetrically distributed relative to the adjusting screw.

[0011] Since the adjusting screw is located between the two elastic clamping pieces, and the elastic clamping pieces are symmetrically distributed relative to the adjusting screw, when the adjusting screw extends between the elastic clamping pieces, the adjusting screw can support the steel bar and cooperate with the elastic clamping pieces to further clamp and fix the steel bar.

[0012] Preferably, the buckle device further comprises a fixing seat, and the fixing seat is threadedly connected to the adjusting screw;

[0013] The elastic clamping piece is arranged on a side of the fixing seat away from the cushion block.

[0016] Preferably, the elastic clamping piece is in an arc shape, and has a plurality of clamping parts on the inner side of the elastic clamping piece.

[0017] By arranging a clamping part on the inner side of the elastic clamping plate, the clamping effect between the elastic clamping plate and the steel bar is increased, so that the elastic clamping plate can fix the steel bar more firmly, avoiding the control structure of the present application being easily offset during concrete pouring due to insufficient clamping force of the elastic clamping plate, thereby affecting the thickness of the concrete layer.

[0018] Preferably, the outer side of the elastic clamping sheet has a plurality of grooves;

[0019] There is a first angle between the channel-shaped member and the fixing seat;

[0020] It also includes an elastic support sheet, one end of which abuts against the first angle, and the other end of which abuts against the groove.

[0021] The elastic clamping piece is strengthened by the elastic support piece to increase the clamping force of the elastic clamping piece when clamping the steel bar, so that the elastic support piece can effectively hold the steel bar.

[0022] Preferably, the channel-shaped member and the elastic clamping piece are integrally formed.

[0023] Preferably, a threaded channel is provided on the fixing seat, and the threaded channel passes through the fixing seat and the groove-shaped member;
