Description

Technical Field

[0001] The utility model belongs to the technical field of bridge pier construction, in particular to a clamp for simply positioning a protective layer of a pier reinforcement bar. Background Art

[0002] In bridge engineering, piers are crucial components and crucial to a bridge's stability. Ensuring the thickness of the pier's reinforcement cover is crucial to the quality of pier construction. Existing techniques primarily rely on manual positioning or the fabrication of large pier positioning frames. However, for variable-section piers, the former is labor-intensive and difficult to locate, potentially compromising the pier structure. The latter significantly increases material consumption and operational costs.

[0003] In order to effectively solve the problem of pier body reinforcement positioning, control the thickness of the pier body protective layer, improve construction efficiency and save operation costs, a method for simply positioning the pier body reinforcement protective layer is urgently needed. Summary of the Invention

[0004] The purpose of the utility model is to provide a simple positioning fixture which can realize the positioning of the pier body steel bars, prevent the deviation of the pier body steel bars and effectively ensure the thickness of the protective layer of the pier body steel bars.

[0005] The utility model is achieved in this way:

[0006] A fixture for simply positioning the protective layer of pier body steel bars is characterized by comprising: a hook steel bar, a nut and a screw rod. The hook steel bar is composed of a short rod and a long rod connected together and forming an angle. The hook composed of the short rod and the long rod hooks the pier body steel bars above the template downward. The lower end side wall of the long rod is welded and fixed to the nut to form a whole. The side wall of the long rod contacts the side wall of the template. The nut is located below the bottom of the template. The screw rod is screwed into the nut so that the top end of the screw screwed into the nut presses against the bottom of the template.

[0007] A protective layer pad is provided between the pier body reinforcement and the formwork to fix the clamps and reinforcement.

[0008] The angle between the short rod and the long rod is 135°.

[0009] The utility model comprises: a hook steel bar, a nut and a screw. The short and long rods of the hook steel bar form a hook that hooks downwardly onto the pier body steel bar above the formwork. The side wall of the long rod contacts the side wall of the formwork. The nut fixed to the lower end side wall of the long rod is located below the bottom of the formwork. The screw is screwed into the nut so that the top end of the screw screwed into the nut presses against the bottom of the formwork. The utility model has the following advantages:

[0010] 1. By rotating the screw locking nut, the pier body reinforcement is driven to achieve the positioning of the pier body reinforcement protection layer (the pier body reinforcement protection layer is the distance between the pier body reinforcement and the formwork), preventing the pier body reinforcement from deviating and effectively ensuring the thickness of the pier body reinforcement protection layer, thereby greatly improving the structural quality of the pier body and providing protection for the structural safety and design service life of the bridge;

[0011] 2. One side of the pier body reinforcement is driven by the positioning fixture to avoid the pier body reinforcement protection layer being too large, and the other side is restricted by the protection layer pad to avoid the pier body reinforcement protection layer being too small;

[0012] 3. No complicated processing is required. The existing materials and protective layer pads can be used to position the steel bars through interaction, thus simplifying the complicated procedures.

[0013] 4. By using simple materials and facilitating processing, it greatly saves materials and improves material utilization;

[0014] 5. It has simple structure, convenient operation and strong popularity. Through simple operation, it can realize the control of the steel bar protective layer of the pier body, which greatly improves the construction efficiency.

[0015] After the installation of the utility model is completed, the size of the pier body steel bar protective layer can be quickly and conveniently adjusted by twisting the screw rod to drive the pier body steel bar according to the needs of the site. The utility model is easy to operate, has high popularity, and has good engineering promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be described in further detail below with reference to the embodiments and accompanying drawings.

[0020] A fixture for simply positioning the protective layer of pier body steel bars comprises: a hook steel bar 1, a nut 2 and a screw 3. The hook steel bar 1 is composed of a short rod 11 and a long rod 12. The short rod 11 and the long rod 12 connected as one form an angle of 135°. The hook formed by the short rod 11 and the long rod 12 hooks downwardly onto the pier body steel bar 4 above the template 5. The lower end side wall of the long rod 12 is welded and fixed to the nut 2 to form a whole. The side wall of the long rod 12 contacts the side wall of the template 5. The nut 2 is below the bottom of the template 5. The screw 3 is screwed into the nut 2 so that the top end of the screw 3 screwed into the nut 2 presses against the bottom of the template 5, thereby connecting the fixture to the pier body steel bar 4 and the template 5 as one.

[0021] A protective layer pad 6 is provided between the pier body reinforcement 4 and the formwork 5 to fix the clamps and reinforcement.

[0022] The length of the long rod 12 of the hook steel bar 1 is produced on site according to the requirements of the pier body protective layer.

[0023] The nut 2 and the screw 3 are selected as needed according to the size and stress conditions of the pier body reinforcement 4.

[0024] Working principle: The angle between the short rod 11 and the long rod 12 of the hook steel bar 1 is clamped to the pier body steel bar 4 above the template 5. The hook steel bar 1 is hooked with the pier body steel bar 4, and the side wall of the long rod 12 is in conflict with the side wall of the template 5. The nut 2 is below the bottom of the template 5. You only need to turn the screw 3 so that the top of the screw 3 screwed into the nut 2 presses against the bottom of the template 5, thereby driving the overall movement of the positioning fixture to achieve the purpose of positioning the pier body steel bars.

[0025] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is determined by the appended claims rather than the foregoing description, and it is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
