Description

Technical Field

[0001] The utility model relates to the field of building construction, and in particular to a controller suitable for controlling the floor slab thickness and the steel bar protection layer thickness. Background Art

[0002] The floor slab thickness controller is usually used to detect and control the actual thickness of the concrete floor slab during the pouring process. In architectural design, there are clear requirements for the floor slab thickness. Ensuring that the specified thickness is achieved is to make the floor slab have sufficient load-bearing capacity and stability. During construction, the thickness controller can help construction workers monitor and adjust the thickness of the concrete pouring in real time, avoiding the floor slab being too thin or too thick.

[0003] After retrieval, the Chinese patent publication number is: CN210395869U, which discloses a floor slab thickness and floor slab steel bar protection layer thickness controller, including a cylindrical first thickness control block and a second thickness control block. The first thickness control block and the second thickness control block are connected by a telescopic connecting rod. The telescopic connecting rod coincides with the axes of the first thickness control block and the second thickness control block. A first cross groove for placing the upper layer of steel bars is arranged above the first thickness control block, and a second cross groove for placing the lower layer of steel bars is arranged below the second thickness control block.

[0004] The above patent solves the problem that the thickness controller cannot control the floor slab thickness and the floor slab steel bar protection layer thickness. The first thickness control block and the second thickness control block are connected by a telescopic connecting rod, so that the distance between the first thickness control block and the second thickness control block can be adjusted to meet the needs of different floor slab thicknesses and floor slab steel bar protection layer thicknesses. At the same time, cross grooves for placing steel bars are arranged on the first thickness control block and the second thickness control block, so that the thickness controller can be accurately installed.

[0005] The traditional floor slab thickness controller or steel bar stools made by adding cement pads in the middle of the upper and lower layers of steel bar meshes are used to control the floor slab thickness and the protection layer. Due to the easy occurrence of chipping and corner loss of the cement pads, the laying spacing and processing of the steel bar stools are not standardized, the installation accuracy of the workers' operation is low, and the radiation surface of the concrete pouring completion surface controlled by pulling a wire at a certain distance exceeding the steel bar surface layer is incomplete, which is inconvenient to use and difficult to effectively control the floor slab thickness and the steel bar protection layer.

[0006] Therefore, the utility model provides a controller suitable for controlling the floor slab thickness and the steel bar protection layer thickness. Summary of the Utility Model

[0007] The purpose of the utility model is to solve the defects existing in the prior art and provide a controller suitable for controlling the floor slab thickness and the steel bar protection layer thickness.

[0014] As a preferred implementation manner, the control steel bar is made of 14mm truss web bar according to the floor slab protective layer thickness.

[0015] The technical effect of adopting the above technical solution is: The size of the control steel bar can be flexibly adjusted according to different floor slab thickness requirements, so as to meet the needs of various building structures.

[0016] As a preferred implementation manner, the support steel bar is made of 8mm round steel.

[0017] The technical effect of adopting the above technical solution is: The support steel bar has sufficient strength and stability, can withstand the pressure and impact during the concrete pouring process, and ensures the stability of the entire controller.

[0018] As a preferred implementation manner, the control steel bar and the support steel bar are connected by welding.

[0019] The technical effect of adopting the above technical solution is: The welding connection method can provide strong connection strength, ensuring that the control steel bar and the support steel bar will not loosen or fall off during the construction process.

[0020] Compared with the prior art, the advantages and positive effects of the present utility model are that,

[0021] The utility model ensures that during the concrete pouring process, the plate vibrator can closely construct against the controller by setting the control component structure and using the plate thickness and protective layer thickness controllers. These controllers are cross-supported and fixed with the PC board and the truss web bars with the assistance of the PC board truss steel bars. The structural design of such controllers is simple and easy for on-site workers to operate. Moreover, with the assistance of the truss steel bars, the stability of the controllers is ensured, thus simplifying the construction process and reducing the dependence on workers' skills. Secondly, since the controllers are designed to be detachable and reusable, the dependence on disposable materials is reduced, thereby reducing the material cost. At the same time, the cleaning and waste treatment work after construction is reduced, further saving costs. It can effectively solve the instability problems of traditional cement cushion blocks and steel stools. With the assistance of the truss steel bars, the stability and accuracy of the controllers are ensured. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Such as Figures 1-4As shown in the figure, this embodiment provides a technical solution: a controller suitable for controlling the floor slab thickness and the thickness of the steel bar protection layer, including a control component 1. The control component 1 includes a control steel bar 11 and a support steel bar 12. The control steel bar 11 and the support steel bar 12 are connected by welding. The control steel bar 11 is made of 14mm steel bar according to the thickness of the floor slab protection layer, and the support steel bar 12 is made of 8mm round steel. The bottom end of the control steel bar 11 is fixedly connected with an upper chord bar 13 of the truss. On both ends of the outer side of the upper chord bar 13 away from the control steel bar 11, there are fixedly connected with web bars 14 of the truss. One end of the support steel bar 12 away from the control steel bar 11 is fixedly connected to the web bar 14 of the truss. One end of the web bar 14 away from the upper chord bar 13 of the truss is fixedly connected with a lower chord bar 15 of the truss. There is a PC board 16 arranged outside the lower chord bar 15 of the truss. The control component 1 is mainly composed of the control steel bar 11 and the support steel bar 12. The control steel bar 11 and the support steel bar 12 in the control component 1 are connected by welding to ensure the stability and firmness of the structure. The control steel bar 11 is the main steel bar designed according to the thickness requirement of the floor slab protection layer and is made of 14mm thick steel bar. This design enables the control steel bar 11 to provide sufficient strength and rigidity to ensure that the thickness of the floor slab can be accurately controlled during the concrete pouring process. The support steel bar 12 is made of 8mm round steel and is used to support and stabilize the position of the control steel bar 11. It is welded to the control steel bar 11 to provide additional support during the construction process to prevent the control steel bar 11 from shifting or deforming and ensure the accuracy of thickness control. The bottom end of the control steel bar 11 is fixedly connected with an upper chord bar 13 of the truss. The function of the upper chord bar is to provide a stable support structure for the control steel bar 11 to make the whole controller more stable during the construction process. On both ends of the outer side of the upper chord bar 13 away from the control steel bar 11, there are fixedly connected with web bars 14 of the truss. The web bars 14 of the truss play a role in enhancing the rigidity of the whole truss structure so that it can withstand various stresses during construction. The lower chord bar 15 of the truss is fixedly connected with one end of the web bar 14 away from the upper chord bar 13 of the truss to form a complete truss structure. There is also a PC board 16 arranged outside the lower chord bar 15 of the truss. The PC board 16 is arranged outside the lower chord bar 15 of the truss, and its function is to be part of the protection layer to further ensure the thickness of the steel bar protection layer. At the same time, the PC board 16 also has the advantages of corrosion resistance and light weight, which helps to extend the service life of the structure.

[0030] Working principle:

[0031] As Figures 1-4 shown:

[0032] During use: Before the concrete begins to set, the controllers for controlling the slab thickness and the protective layer thickness need to be removed, and the concrete surface must be carefully smoothed. Then, these slab thickness and protective layer thickness controllers will be used to make control steel bars 11 and foot steel bars 12 according to the PC board 16 truss steel bars on site. After the PC board 16 is installed, these controllers will be fixed by the cross support of the foot steel bars 12, PC board 16 and truss web reinforcement 14. During the concrete pouring process, a flat plate vibrator is used. This flat plate vibrator will be constructed close to the slab thickness and steel bar protective layer thickness controller, so as to effectively control the thickness of the floor slab and the thickness of the negative reinforcement protective layer. In addition, the design of the guardrail is very simple and easy to use, convenient for disassembly and reuse, which greatly improves the construction efficiency and quality.
