Detailed Description

The present invention is described in further detail below with reference to figures 1-3.

The embodiment of the utility model discloses a pier stud steel bar protective layer adjusting device. Referring to fig. 1-3, a pier stud steel bar protective layer adjusting device comprises a screw rod 1, a nut 2, a connecting part 5 and a top contact part 7, wherein the nut 2 is sleeved on the screw rod 1 in a matching manner and is fixed with two adjacent steel bars 3 through the connecting part 5; through setting up top contact 7, can avoid screw rod 1 directly to push up on template 4, lead to the not good pivoted problem when twisting rotatory screw rod 1 of people. In order to avoid the top contact 7 from easily sliding on the template 4, the top contact 7 is made of a non-slip material on the side close to the template 4.

In order to match with a wrench, the screw rod 1 is easier to operate and rotate, the wrench part 6 is arranged at the other end of the screw rod 1, and the outer contour of the cross section of the wrench part 6 is in an equilateral hexagon shape.

In this embodiment, there are two connecting portions 5, specifically, each connecting portion includes a support bar 51 and two clamping sleeves 53 capable of clamping the steel bars 3, the two clamping sleeves 53 are welded to the support bar 51 at a certain distance, and a center distance between the two clamping sleeves 53 is the same as a center distance between two adjacent steel bars 3; the two connecting parts 5 are respectively welded on the top surface and the bottom surface of the nut 2 through the supporting bars 51, and after welding, the nut 2 is arranged in the middle of the supporting bars 51.

In the in-process of actual construction, the deviation probably can appear in the distance between two adjacent reinforcing bars, for the application scope of increase this device, can establish connecting portion into adjustable, can avoid leading to not good fixed problem because of the inconsistent size between the adjacent reinforcing bar, application scope is wider. Specifically, a sliding block 52 can be further arranged between the supporting bar 51 and the clamping sleeve 53, a T-shaped groove 511 is formed in the supporting bar 51 in the length direction, a convex block 521 matched with the groove 511 is arranged on the sliding block 52, the supporting bar 51 is connected with the sliding block 52 in a sliding fit mode, and the clamping sleeve 53 is fixed on the sliding block 52, so that the sliding block 52 can slide on the supporting bar 51 to be adjusted to a proper position to clamp the reinforcing steel bars.

In order to avoid the problem that the slider 52 slides out of the supporting bar, which is easy to lose or slide down, and then reinstalled, in this embodiment, one end of the two end portions of the groove 511 in the length direction of the supporting bar 51 is through, the other end is not through, and a stopper 54 is disposed on the side that is not through. Of course, both ends of the groove 511 may be penetrated in the longitudinal direction of the supporting bar 51, and one stopper 54 may be provided at both ends.

The implementation principle of the pier stud steel bar protective layer adjusting device provided by the embodiment of the utility model is as follows: the nut 2 on the screw rod 1 is screwed to be close to the top contact part 7, the nut 2 and the top contact part 7 are placed between the steel bar 1 and the template 4 which need to be adjusted in position, the two adjacent steel bars 1 are clamped by the clamping sleeve 53, the screw rod 1 is screwed by the rotation of the wrench, the screw rod 1 advances and is gradually close to the template 4, when the top contact part 7 abuts against the template 4, the screw rod 1 is continuously screwed in the same direction, the nut 2 moves away from the template 4 under the blocking of the template 4, the two steel bars 1 connected with the nut 2 also move away from the template 4, and therefore the distance between the steel bar 1 and the template 4 is increased, and the thickness of a steel bar protection layer is guaranteed.

This device has very good beneficial technological effect at the in-process of in-service use: the abutting piece abuts against the template, the screw in the device is screwed by rotating, the nut can be driven to move away from the template, so that the reinforcing steel bar is driven to move away from the template, and the gap size between the reinforcing steel bar and the template is ensured;
