[0002] In the construction of concrete cast-in-place piles and anchor rods, in order to ensure that the thickness of the steel bar protective layer meets the design requirements, concrete blocks of customized thickness are usually used to tie the steel cage. When the steel cage is moved and lowered into the pile hole, the concrete blocks are easily fallen off or broken due to loose binding or bumps, which cannot ensure the thickness and may even cause the steel cage to get stuck in the pile hole.

[0003] In addition, there are also protective layer thickness measure bars welded on the steel cage made on site. The protective layer thickness is limited by the measure bars. However, the protective layer thickness measure bars are mostly made by hand-bending on site, and the production is random, resulting in the measure bars being of different sizes, making it impossible to guarantee the quality of the protective layer thickness, and increasing various rework costs due to quality problems.

[0030] At the construction site, the protective layer thickness measure bars are mostly made by on-site manual bending, which is haphazardly made, resulting in different sizes of measure bars, which makes it impossible to guarantee the quality of the protective layer thickness, and increases in various rework costs due to quality problems. In view of the technical problems that concrete blocks are easy to fall off and break, and the protective layer thickness measure bars are different in size, resulting in the inability to guarantee the quality of the protective layer thickness, this patent is studied according to the current construction process requirements, and this steel bar protective layer thickness measure bar processing device.

[0031] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is in no way intended to limit the present invention and its application or use. The present invention can be implemented in many different forms and is not limited to the embodiments herein. In the present invention, when a particular device is described as being between a first device and a second device, there may or may not be an intermediate device between the particular device and the first device or the second device. Example

[0032] like Figures 1 to 5 As shown, a reinforcement processing device for measuring the thickness of a steel bar protective layer comprises a stand, a bearing seat 2 and a movable pressure rod 3; the bottom frame and the top frame of the stand are connected by a column 13, a bearing cross bar 12 is arranged at the front end of the bottom frame, the front end of the top frame is open and bearing longitudinal bars 14 are arranged on both sides in the lateral direction, and a limiting cross bar 15 is arranged at the rear end; the bearing seat 2 is relatively arranged on the bearing longitudinal bars 14 on both sides, and the bearing seat 2 is configured to support the two ends of the steel bar workpiece that needs to be bent; the front end of the movable pressure rod 3 is hinged on the bearing cross bar 12, and is configured to rotate around the bearing cross bar 12 to apply a pressure load to the middle of the steel bar workpiece to produce bending deformation, and the limiting cross bar 15 is configured to limit the terminal angle of the movable pressure rod after rotating around the bearing cross bar 12.

[0033] In a specific implementation, the two longitudinal bearing rods 14 are respectively provided with position identification lines arranged along the longitudinal array and at uniform intervals, which can accurately mark the position of the bearing seat 2, more conveniently confirm the consistent position of the bearing seat 2 after movement, and facilitate on-site operation.

[0034] like Figure 4 As shown, the provided steel bar protective layer thickness measure bar processing device is used. First, the bearing seat 2 is moved to the set position of the bearing longitudinal rod 14 and fixed by the positioning screw 23. The straight steel bar raw material 4a is placed on the bearing seat 2. The handle 32 of the movable pressure rod 3 is held and the pressure rod is moved forcefully until it stops at the limiting cross bar 15. The measure bar is deformed downward by the pressure of the movable pressure rod 3 to obtain a small curvature measure bar 4b with uniform deformation.

[0035] Among them, the load-bearing cross bar 12, the connecting longitudinal bar 11 and the rear end cross bar of the bottom frame enclose a closed bottom rectangular structure, the rear ends of the load-bearing longitudinal bars 14 on both sides of the top frame are connected to the limiting cross bar 15 to form a top rectangular structure with an open front end, and the columns 13 are connected between the corner points of the bottom rectangular structure and the top rectangular structure.

[0036] In the real-time process, each rod is made of 12mm diameter round tube, the column is made of 12mm round tube or 20*20mm square tube with 1mm wall thickness, the movable pressure rod is made of 14mm diameter round steel, and the handle is made of rubber non-slip handle. Example

[0037] like Figure 1 and Figure 2 As shown, based on the first embodiment, the structure is optimized: the bearing seat 2 is adjustable in front and rear position on the bearing longitudinal rod 14 , and a positioning screw 23 is provided between the bearing seat 2 and the bearing longitudinal rod 14 .

[0038] like Figure 5 As shown, when a measure reinforcement with a larger curvature is required, the two bearing seats are adjusted in the direction of the bearing cross bar 12 and fixed by positioning screws 23, the straight steel bar raw material 4a is placed on the bearing seat, the handle 32 of the movable pressure rod 3 is held and the pressure rod is moved forcefully until it stops at the limiting cross bar 15, and the measure reinforcement is deformed downward by the pressure of the movable pressure rod 3 to obtain a measure reinforcement 2 with a large curvature.

[0039] Further, the bearing seat 2 includes a main seat body and a sub-seat body 22 sleeved on the bearing longitudinal rod 14, the positioning screw 23 is arranged between the main seat body and the bearing longitudinal rod 14, the sub-seat body 22 is provided with a bearing groove for accommodating a steel workpiece, further, the sub-seat body 22 is rotatably connected to the main seat body, the bearing groove is an annular groove arranged on the sub-seat body 22, and the radial cross section of the annular groove is an arc shape. The setting of the arc-shaped bearing groove can adapt to steel raw materials of different diameters to obtain a measure bar with a consistent shape.

[0040] Furthermore, the auxiliary seat body 22 is provided with a first bearing member that is slidably matched with the bearing longitudinal rod 14, and a second bearing member is provided between the auxiliary seat body 22 and the main seat body. The deformation of the end of the steel bar raw material during the bending process is transmitted through the rotation of the bearing member, avoiding sliding friction between the steel bar raw material and the bearing seat, thereby reducing the required pressure rod load and the required manual pressure. Example

[0041] like Figure 1 , Figure 4 and Figure 5 As shown, based on the first and second embodiments, the structure is optimized:

[0042] The movable pressure rod 3 includes a multi-section movable rod body 31 that is slidably matched. The front end movable rod body 31 is rotatably connected to the load-bearing cross bar 12, and a handle 32 is provided on the rear end movable rod body 31. Before using the movable pressure rod 3 to apply a load downward, the length of the movable pressure rod 3 can be adjusted to increase the force arm, thereby reducing the size of the manual pressure, saving the pressure applied by the hands, and reducing labor intensity.

[0043] like Figure 6As shown, the provided steel bar protective layer thickness measure bar processing device is used, and the arc shape of the formed measure bars is consistent. The obtained measure bars are welded or tied around the steel cage, and lowered into the pile pit 6. Through the support of the large curvature measure bars 4c, the thickness of the steel cage 5 is consistent with the inner wall of the pile pit, ensuring that the thickness of the protective layer between the steel cage and the inner wall of the pile hole 6 is consistent, improving the construction quality of the protective layer, and effectively solving the problem that the quality of the protective layer thickness cannot be guaranteed due to the random on-site production of measure bars and different standards, and reducing the increase of various rework costs due to quality problems.
