Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a controller for the cross-sectional dimensions of concrete components and the thickness of the reinforcing steel protective layer. Background Technology

[0002] In the construction industry, on-site concrete structure construction often results in substandard concrete dimensions and cover thickness due to deviations in formwork erection or rebar displacement. This problem is particularly prominent in critical load-bearing components such as beams, columns, and walls. Dimensional deviations can lead to a decrease in structural load-bearing performance, while insufficient cover thickness accelerates rebar corrosion, severely affecting the durability and safety of the structure. It can also cause issues such as failing quality acceptance, rework, and rectification, thereby increasing project costs and delaying the construction period.

[0003] Traditional control methods mainly rely on welding limiting steel bars or placing plastic / concrete protective layer spacers, but these methods have obvious drawbacks: welding operations are inefficient and damage the original properties of the steel bars; spacers are prone to displacement and breakage, making it difficult to guarantee positioning accuracy; and there is a lack of effective three-dimensional spatial positioning means during construction, resulting in poor overall position control of the steel mesh. Utility Model Content

[0004] This invention provides a controller for the cross-sectional dimensions of concrete components and the thickness of the concrete cover layer, which can solve the problems of low construction efficiency and poor accuracy in controlling the cross-sectional dimensions of concrete components and the thickness of the concrete cover layer in existing building construction technologies.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] like Figure 1-5 As shown in the figure, this utility model provides a controller for the cross-sectional dimensions of concrete components and the thickness of the reinforcing steel protective layer, including a first body 1, a second body 2, a movable component 3, and gaskets. The second body 2 is movably connected to the first body 1 and can be adjusted in position along the axial direction of the first body 1; the movable component 3 is movably connected to the second body 2 and can be adjusted in position along the axial direction of the second body 2; the gaskets are respectively fixedly disposed on the movable component 3 and at the ends of the second body 2.

[0033] In use, both ends of this device are used to abut against the building formwork. By adjusting the relative position of the second main body 2 and the first main body 1, the overall length of the device is changed, thus allowing for the fixing and control of the cross-sectional dimensions of concrete components. Then, by adjusting the position of the movable part 3 on the second main body 2, the distance between the shims at the ends of the movable part 3 and the second main body 2 is changed, thereby achieving the positioning and control of the thickness of the reinforcing steel protective layer. This device can be adjusted during installation or uniformly adjusted before use, and then installed into the reinforcing steel and formwork system to ensure the accuracy and uniformity of different dimensional controls.

[0034] Please see Figure 1-5 In one embodiment of this utility model, the first body 1 can be a hollow columnar structure, such as a triangular prism, a quadrangular prism, or a circular structure. The second body 2 is inserted into the first body 1 and is movably connected to the first body 1. The second body 2 can slide with the first body 1 and be locked by fasteners such as bolts, pins, or screws. Preferably, the first body 1 can be a circular sleeve 4, and the second body 2 can be a circular screw 5 that mates with it. The screw 5 is threadedly engaged with the sleeve 4 so that the relative position of the screw 5 and the sleeve 4 can be easily adjusted.

[0035] Please see Figure 1-5 In one embodiment of this utility model, the first body 1 may include two fixedly connected sleeves 4, the fixed connection being welding. The two sleeves 4 partially overlap. The second body 2 includes two screws 5, which are threadedly engaged with the two sleeves 4 respectively. By providing two staggered and partially overlapping sleeves 4, the two sleeves 4 are not coaxial, and the screws 5 have sufficient adjustment space within the sleeves 4. The dimensions of the sleeves 4 may be an inner diameter of 10mm and a length of 100mm. The length of the overlapping portion of the two sleeves 4 (i.e., the welding length) may be 50mm. The dimensions of the screws 5 are an outer diameter of 10mm and a length of 100mm.

[0036] Please see Figure 1-5 In one embodiment of this utility model, the movable component 3 can be a slider slidably sleeved on the second body 2, and can be locked by a fixing component (such as a bolt, pin, screw, etc.). Preferably, the movable component 3 is a nut 6 threaded onto the screw 5.

[0037] Please see Figure 1-5 In one embodiment of this utility model, gasket structures can be provided at both ends of the device and on the movable part 3. Specifically, a gasket 7 is fixedly connected to the end of the screw 5 away from the sleeve 4, and a gasket 7 is provided on each of the two screws 5. In use, the gasket 7 is used to contact the construction template to ensure the stability of the device and the support effect on the template. A second gasket 8 is fixedly connected (e.g., welded) to the nut 6, and the second gasket 8 is used to weld to the reinforcing bar. The gasket can be made of steel, and the size of the gasket is 30mm × 15mm × 2mm.

[0038] The working principle of this utility model:

[0039] In use, nut 6 is fitted onto screw 5 and its position is adjusted so that the distance between washer 7 and washer 8 meets the requirements. Then, screw 5 is screwed into sleeve 4 and its relative position is adjusted to control the overall length of the device. During construction, washer 7 is supported on the formwork and washer 8 is welded to the reinforcing steel.

[0040] The screw 5 is helically inserted into the sleeve 4, and the relative position between the two can be adjusted to control the overall length of the device. The gaskets 7 at both ends abut against the template, thus controlling the cross-sectional dimensions of the concrete component. On the other hand, by adjusting the position of the nut 6 on the screw 5, the distance between gaskets 7 and 8 can be changed. Gasket 8 can be welded to the reinforcing steel to ensure the stability of the entire device. The spacing between the two gaskets allows for precise control of the protective layer thickness.

[0041] This utility model, through its modular design, boasts advantages such as simplified components and a compact structure, offering high construction convenience and installation efficiency. It enables rapid installation and adaptive adjustment. The device can adapt to the cross-sectional dimension adjustment needs of shear walls and structural slabs under different working conditions, simultaneously achieving precise control of the reinforcement protective layer thickness. It effectively solves common quality problems in traditional construction, such as cross-sectional dimension deviations and substandard protective layer thickness caused by reinforcement arrangement deviations and formwork displacement. The device employs non-destructive installation technology, allowing for precise control of concrete cross-sections and reinforcement protective layer thicknesses according to different design requirements. Its innovative structure effectively avoids misalignment or reinforcement displacement during formwork erection, eliminating quality defects such as cross-sectional dimension deviations and substandard protective layer thickness in concrete structures from the source of the process. The length of the sleeve and threaded rod should not be limited; the dimensions of the sleeve 4, threaded rod 5, and washer can be selected according to actual conditions.
