Description

Technical Field

[0001] This utility model belongs to the field of steel reinforcement protection and adjustment technology for thin-walled hollow piers, specifically a tool for adjusting the spacing of the steel reinforcement protective layer in thin-walled hollow piers. Background Technology

[0002] Thin-walled hollow piers are a widely used type of bridge pier in bridge engineering. Their characteristic is that while their transverse length is the same as other types of piers, their longitudinal length is shorter. This design saves materials, reduces the pier's self-weight, increases the pier's stiffness, reduces the negative bending moment at the main beam supports, and enhances the bridge's aesthetics.

[0003] Meanwhile, a device for controlling the spacing and protective layer thickness of steel bars in a thin-walled hollow pier, with application number 202322535310.0, is described. This device includes an outer pier and an inner pier, with two sets of steel reinforcement skeletons between them. Square blocks are fitted around the outer sides of each set of steel reinforcement skeletons, and a support mechanism is provided outside the square blocks. In practice, when adjusting the spacing and protective layer thickness of the steel bars in this device, the steel reinforcement structure is tightened by a positioning structure using a support plate and a binding structure. Simultaneously, the spacing adjustment uses multiple pads for limiting, resulting in poor stability. Alternatively, directly using wire winding for positioning is also problematic.

[0004] Therefore, a tool for adjusting the spacing of the reinforcing steel protective layer in thin-walled hollow piers is proposed to address the above problems. Summary of the Invention

[0005] To address the problems mentioned in the background art, this utility model provides a tool for adjusting the spacing of the reinforcing bar protective layer of a thin-walled hollow pier. It has the advantages of using staggered reinforcing bars, reinforcing bars to reinforce the structure, and forming a protective layer in the gaps of the formwork to protect the thin-walled hollow pier.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tool for adjusting the spacing of the protective layer of steel bars in a thin-walled hollow pier, including a support platform, a template fixedly installed at the top of the support platform, and a thin-walled hollow pier steel bar protection component further included in the hollow gap of the template.

[0007] The thin-walled hollow pier reinforcement protection component includes vertical steel bars fixedly installed on the inner wall of the gap of the thin-walled hollow pier reinforcement protection component. Horizontal steel bars are tied to the outside of the vertical steel bars by steel wires. Tensioning steel bars are tied at the intersection of the vertical steel bars and the horizontal steel bars. The vertical steel bars also include a spacing adjustment component.

[0008] The spacing adjustment assembly includes a fixing block sleeved on the outside of the transverse reinforcing bar, and an adjustment sleeve fixedly installed on one side of the fixing block facing each other. An adjustment screw is installed inside the two adjustment sleeves.

[0009] Preferably, both ends of the tensioning bar are fixedly provided with anti-disengagement buckles that fit at the intersection of the vertical and horizontal bars on the other side.

[0010] Preferably, the outer side of the fixing block is fitted with a top plate that fits into the inner wall of the template gap.

[0011] Preferably, a square plate is fixedly provided at the top of the fixing block, and an adjusting screw rod rotatably connected to the top plate passes through the interior of the square plate.

[0012] Preferably, one end of the adjusting screw is rotatably connected to one of the adjusting sleeves, and the other end of the adjusting screw is helically connected to another adjusting sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model uses the interlaced steel bars of the thin-walled hollow pier steel bar protection component for reinforcement and protection, and the spacing adjustment component can be used to adjust the spacing between the steel bars. It is convenient to use and increases the structural strength and service life of the thin-walled hollow pier with the thin-walled hollow pier steel bar protection component.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, this utility model provides a tool for adjusting the spacing of the protective layer of steel bars in a thin-walled hollow pier, including a base 1, a template 2 fixedly installed on the top of the base 1 to form a hollow pier structure for use, and a thin-walled hollow pier steel bar protection component 3 is also included in the hollow gap of the template 2.

[0023] The thin-walled hollow pier reinforcement protection component 3 includes vertical steel bars 31 fixedly installed on the inner wall of the gap of the thin-walled hollow pier reinforcement protection component 3. Horizontal steel bars 32 are tied to the outside of the vertical steel bars 31 by steel wire. Tensioning steel bars 33 are tied at the intersection of the vertical steel bars 31 and the horizontal steel bars 32. The added vertical steel bars 31, together with the horizontal steel bars 32, form a reinforcement structure for positioning and form a protective layer. Spacing adjustment components 4 are also included between the vertical steel bars 31.

[0024] The spacing adjustment assembly 4 includes a fixing block 41 sleeved on the outside of the transverse steel bar 32. An adjustment sleeve 42 is fixedly installed on the opposite side of the fixing block 41. An adjustment screw 43 is installed inside the two adjustment sleeves 42. Rotating the adjustment screw 43 moves the adjustment sleeve 42 to form a reinforced spacing adjustment structure.

[0025] Specifically, both ends of the tensioning rebar 33 are fixedly provided with anti-disengagement buckles 34 that fit at the intersection of the vertical rebar 31 and the horizontal rebar 32 on the other side. The tensioning rebar 33 can be positioned at the connection point of the rebar through the anti-disengagement buckle 34 structure for tensioning and positioning.

[0026] A top plate 46 is fitted to the outer side of the fixing block 41 and fits against the inner wall of the gap in the template 2. A square plate 44 is fixedly installed at the top of the fixing block 41. An adjusting screw 45, which is rotatably connected to the top plate 46, passes through the inside of the square plate 44. One end of the adjusting screw 43 is rotatably connected to one of the adjusting sleeves 42, and the other end of the adjusting screw 43 is helically connected to another adjusting sleeve 42. By rotating the adjusting screw 43 inside one of the adjusting sleeves 42, the adjusting sleeve 42 at the other end is controlled to move outward to adjust the spacing.

[0027] The thin-walled hollow pier composed of the foundation 1 and the formwork 2 is existing technology and will not be described in detail here.

[0028] Working principle and process:

[0029] Workers bundled the vertical reinforcing bars 31 and horizontal reinforcing bars 32 from the thin-walled hollow pier reinforcement protection component 3 with steel wire and placed them into one side of the inner wall of the gap in the template 2. They then positioned them on the other side to form an integral structure for use. The tensioning reinforcing bars 33 were placed at the intersection of the horizontal reinforcing bars 32 and the vertical reinforcing bars 31 and secured with anti-disengagement buckles 34 for a more stable setup. A spacing adjustment component 4 was added to the outside of the horizontal reinforcing bars 32. During setup, the first adjusting screw 43 was rotated to control its rotation inside the adjusting sleeve 42, which in turn pushed the adjusting sleeve 42 on the other side to unfold. This caused the fixing blocks 41 on both sides to move the positioned horizontal reinforcing bars 32 to both sides, closer to the inner wall of the gap in the template 2. Finally, the gap was adjusted by rotating the second adjusting screw 45 inside the square plate 44, which pressed the top plate 46 at the other end against the inner wall of the template 2, reducing gaps and making the positioning more secure, thus protecting the hollow pier.
