Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a device for controlling the protective layer of reinforcing bars. Background Technology

[0002] During the construction of reinforced concrete structures, it is often necessary to control the thickness of the protective layer on the outside of the reinforcing bars. For example, in the pouring of the top slab, the top slab is usually poured in sections. Supporting formwork is set up below the top slab, and horizontal and vertical reinforcing bars are arranged crosswise inside the top slab to strengthen its strength. Side formwork is erected at the construction joints of the top slab to seal them, and spacers are added between the supporting formwork and the reinforcing bars at the construction joints to ensure the thickness of the protective layer of the top slab.

[0003] Regarding the structure for controlling the thickness of the concrete cover, for example, a concrete cover controller provided by patent publication number CN209780048U is installed at the construction joint of the top slab. It includes multiple control strips, which are placed between the longitudinal reinforcement and the supporting formwork. The thickness of the control strips is the same as the thickness of the concrete cover. The upper end surface of the control strips is provided with receiving grooves that are spaced apart with the same spacing as the adjacent longitudinal reinforcement. The longitudinal reinforcement is placed in the receiving grooves. The thickness of the control strips is the same as the thickness of the concrete cover. It is placed between the reinforcement and the supporting formwork to facilitate the control of the concrete cover of the top slab.

[0004] Based on the above search and analysis of existing technologies, it has been found that existing rebar cover control devices, similar to those disclosed above, have a fixed and non-adjustable thickness, which limits their application. Therefore, a rebar cover control device is proposed to address these issues. Utility Model Content

[0014] As a further supplement to this solution, assembly blocks are installed on both ends of the support base along its length, and adjacent support units are fixed together by the assembly blocks and bolts.

[0015] As a further supplement to this solution, a transmission groove is provided at one end of the transmission rod, and a transmission block that matches the transmission groove is fixed at the other end of the transmission rod located outside the support base.

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.

[0028] Example: Reference Figure 1-5 The reinforcement protective layer control device shown includes multiple support units 1. The support unit 1 includes a support base 12, a telescopic support part 13 and a fixed base 11 from top to bottom. The side end of the fixed base 11 is fixed with an installation block 14. The support unit 1 can be fixed to the installation surface by bolts and the installation block 14.

[0029] Multiple telescopic support parts 13 are provided, and the multiple telescopic support parts 13 are fixed at equal intervals between the fixed seat 11 and the support seat 12 along the length direction of the fixed seat 11 and the support seat 12. An operating mechanism is installed on the support seat 12, and the operating mechanism is connected to the multiple telescopic support parts 13 to drive the multiple telescopic support parts 13 to extend and retract synchronously. This makes it convenient to adjust the height of the support unit 1 according to actual needs, thereby controlling the overall thickness of the steel reinforcement protective layer, making it more flexible to use and with a wider range of applications.

[0030] The telescopic support 13 includes a limiting sleeve 131, a limiting post 132, and a threaded post 133. The limiting sleeve 131 is vertically fixed to the lower end of the support base 12, the limiting post 132 is vertically fixed to the upper end of the fixed base 11, and the limiting post 132 is slidably sleeved on the inner side of the limiting sleeve 131. The threaded post 133 is vertically threaded through the limiting post 132, and the threaded post 133 is connected to the operating mechanism.

[0031] Regarding the operating mechanism, specifically, the operating mechanism includes a transmission rod 15 and multiple reversing components. The transmission rod 15 is rotatably mounted on the inner side of the support base 12 along the length direction of the support base 12. The multiple reversing components are connected one-to-one between the multiple threaded columns 133 and the transmission rod 15. Specifically, the reversing components include a first bevel gear 16 and a second bevel gear 17. The first bevel gear 16 is coaxially fixed with the transmission rod 15, and the second bevel gear 17 is coaxially fixed with the top end of the threaded column 133 and meshes with the first bevel gear 16.

[0032] In order to facilitate the extended assembly of the support unit 1, the support base 12 is equipped with assembly blocks 110 on both sides along its length direction, and two adjacent support units 1 are fixed together by the assembly blocks 110 and bolts.

[0033] To facilitate quick adjustment of the overall height of multiple support units 1 in the assembled state, a transmission groove 1501 is provided at one end of the transmission rod 15, and a transmission block 18 that is adapted to the transmission groove 1501 is fixed at the other end of the transmission rod 15 located outside the support base 12.

[0034] Considering that the end of the transmission rod 15 is exposed and prone to accidental contact, the support base 12 is provided with a protective groove 1201 coaxial with the transmission rod 15 on one side near the transmission groove 1501. The other end of the support base 12 is fixed with a protective ring 19 that matches the protective groove 1201. The protective ring 19 is sleeved on the outside of the transmission block 18.

[0035] The working principle of this utility model is as follows: When in use, the support unit 1 is fixed to the mounting surface by bolts and mounting block 14. Multiple support units 1 are selected and assembled according to the actual area of ​​the steel reinforcement protective layer. Specifically, the transmission block 18 on one support unit 1 is inserted into the transmission groove 1501 on another support unit 1, and then the assembly block 110 is used with bolts to fix two adjacent support units 1.

[0036] Next, tools such as pry bars can be used to insert into the transmission groove 1501 on a support unit 1 at the end to rotate the transmission rod 15. The transmission rod 15 rotates synchronously with the threaded column 133 through the meshing action between bevel gear 16 and bevel gear 2 17, thereby extending the telescopic support part 13 to adjust the overall height of the support unit 1 and thus control the overall thickness of the steel reinforcement protective layer.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
