Description

Technical Field

[0001] The utility model relates to a controller for positioning the spacing between horizontal bars and stirrups of a reinforced concrete vertical component, and belongs to the technical field of reinforced concrete construction. Background Art

[0002] The control of the spacing between horizontal bars and stirrups in reinforced concrete vertical components has always been a difficult problem in steel bar construction. The existing methods for positioning the spacing between horizontal bars and stirrups include the skin number rod control method, the longitudinal steel bar stone pencil marking method, the manual support method, etc. These methods are difficult to accurately control the positioning and require temporary reinforcement and manual assistance. They cannot achieve single-person operation and reduce labor, and cannot improve the convenience and economy of construction. At present, there are also some utility model stirrup locators, such as the locator with a positioning ruler and a tongue. This type of locator improves the accuracy of stirrup positioning to a certain extent, but it is not easy to use. Each positioning tongue needs to be manually rotated and operated, which fails to truly solve the labor problem, resulting in a low degree of actual use and promotion. Summary of the invention

[0003] The purpose of the utility model is to provide a controller for positioning the spacing of horizontal bars and stirrups of reinforced concrete vertical components, which is convenient to construct, can be operated by one person, has high work efficiency, high precision, can be reused and has good economic benefits, so as to overcome the shortcomings of the current existing technology.

[0004] In order to solve the above problems, the utility model provides a technical solution for the controller for positioning the spacing of horizontal bars and stirrups of reinforced concrete vertical components: the utility model spacing positioning controller includes an outer first section stainless steel plate and an inner stretch stainless steel plate expansion joint. The outer first section stainless steel plate is tightly connected to the base tray, and the outer first section stainless steel plate is composed of a base tray, a positioning support plate with an anti-slip baffle, a locking hole, and a scale value. The inner stretch stainless steel plate expansion joint is connected to the outer first section stainless steel plate by plugging. The inner stretch stainless steel plate expansion joint is composed of a telescopic spring device, a scale value, a welding plate at the bottom of the spring, and a cylindrical rivet structure type elastic pin card device.

[0005] Holes for locking are provided at set distances on both sides of the stainless steel plate of the outer first section, and the expansion joint of the inner stretch stainless steel plate is fixed to the hollow part of the stainless steel plate of the outer first section by plug-in connection. The cylindrical rivet structure type spring pin clamping device is locked and fixed at the locking hole by the locking force of the spring, and the free stretching of the expansion joint of the inner stretch stainless steel plate is achieved by manually pressing the cylindrical rivet structure type spring pin clamping device on both sides.

[0006] The conventional custom length of the outer first section stainless steel plate and the inner stretch stainless steel plate expansion section is 1.5m or 2.0m, which can meet the construction requirements of floor height within 4.0m. If the construction height is to be increased, the custom length can be increased by adjusting the steel plate specification parameters to meet the requirements of anti-bending and anti-overturning.

[0007] The first section of the outer stainless steel plate and the inner stretch stainless steel plate expansion joint are equipped with spacing scales and corresponding welded positioning plates on the left and right sides. The center spacing of each adjacent welded positioning plate on the left side of the first section of the outer stainless steel plate and the inner stretch stainless steel plate expansion joint is 150mm, and the center spacing of each adjacent welded positioning plate on the right side is 100mm, which can achieve accurate positioning of the horizontal reinforcement and stirrup spacing of 100mm or integer multiples of 150mm. If there are special spacing requirements, the positioning spacing scale can be adjusted and customized to achieve different spacing multiples.

[0008] A base tray is set at the bottom of the first section of the stainless steel plate, which can fix displacement and resist overturning, ensuring that the controller will not be displaced or overturned due to the pressure of the steel bars. A positioning tray with anti-slip baffles is welded axially on the steel plate at a fixed spacing, so that all the horizontal bars and stirrups in the entire construction height can be directly placed on the positioning tray of the corresponding scale. By placing two or more positioning controllers of the utility model symmetrically or at intervals, it can fix the horizontal bars and stirrups and support the steel bars, and can accurately locate and fix the spacing of the horizontal bars and stirrups without manual straightening and any additional temporary fixation.

[0009] Through the above technical solution, the utility model uses the positioning support plate as the spacing positioning reference of the horizontal reinforcement and stirrups, and realizes the construction requirements of different floor heights by pressing and stretching to control the height. The positioning support plate has the function of fixing and supporting the reinforcement. Therefore, compared with the prior art, the utility model not only has a simple structure, realizes single-person operation, and reduces labor, but also has the advantages of accurate positioning, high work efficiency, and good turnover economic benefits.

[0022] To facilitate understanding of the present invention, the following description is provided in conjunction with the accompanying drawings and embodiments.

[0023] As attached Figures 1 to 8 The utility model shown in the figure is composed of an outer first section stainless steel plate 1 and an inner stretch stainless steel plate expansion joint 2. The outer first section stainless steel plate 1 is tightly connected to the base tray 3, which can play a role in fixing displacement and anti-overturning, ensuring that the controller will not be displaced or overturned due to the pressure of the steel bars. Figure 1 and Figure 3As shown, the first outer section stainless steel plate 1 is welded with a positioning support plate 4 with an anti-skid baffle along the axial direction. The working steel bars can be directly placed on the positioning support plate 4 with the corresponding scale anti-skid baffle. Due to the strength and anti-overturning ability of the structure itself, the spacing of the horizontal bars and stirrups can be accurately positioned and fixed without manual straightening and without any additional temporary fixation. Positioning holes 5 are set at set distances on both sides of the first outer section stainless steel plate 1. The inner stretch stainless steel plate expansion joint 2 is fixed to the hollow part of the first outer section stainless steel plate 1 by plug-in connection. The cylindrical rivet structure type spring pin card device 9 is fixed at the positioning hole 5 by the locking force of the telescopic spring device 6. The free stretching of the inner stretch stainless steel plate expansion joint 2 is achieved by manually pressing the cylindrical rivet structure type spring pin card device 9 on both sides. As shown Figure 3 and Fig.12 As shown, scale values ​​7 are set on the left and right sides of the outer first section stainless steel plate 1 and the inner stretched stainless steel plate expansion section 2. The center spacing of each adjacent positioning support plate 4 with anti-slip baffle welded on the left side is 150mm, and the center spacing of each adjacent positioning support plate 4 with anti-slip baffle welded on the right side is 100mm. It can realize precise positioning of the horizontal reinforcement and stirrup spacing of 100mm or integer multiples of 150mm, which can meet the conventional use of the horizontal reinforcement and stirrup spacing in the design drawings. If there are special spacing requirements, the spacing module can be customized separately.

[0024] The specific implementation operation sequence is as follows: clean the base layer to ensure that the ground is flat. According to the height of the reinforced concrete vertical component, the cylindrical rivet structure type spring pin bean device 9 is manually pressed on both sides to realize the free stretching of the internal stretching stainless steel plate expansion joint 2 to the desired construction height. The cylindrical rivet structure type spring pin bean device 9 is fixed by the locking force of the spring at the clamping hole 5. Then the controller of the utility model is placed vertically and steadily along the outer skin of the horizontal reinforcement and stirrups. Generally, the horizontal reinforcement of the shear wall and the vertical component of the guardrail is placed symmetrically at intervals on both sides of the inner and outer sides according to the span. Generally, only two stirrups of rectangular or small special-shaped column bodies are placed in axially symmetrical positions. If the component size is oversized or the column body is large and special-shaped, two more symmetrical placements can be added as needed. Then, according to the requirements of the design drawings, the horizontal reinforcement or stirrups are placed from bottom to top in the positioning support plate 4 with anti-slip baffles at the corresponding spacing, and the outer skin of the working steel bar fits the vertical surface of the outer first section stainless steel plate 1. At this time, the horizontal reinforcement and stirrups have been accurately positioned and fixed in the corresponding positions, and then they can be tied according to the process requirements. After the tying is completed, the controller of the utility model can be removed and transferred to other parts for use. This process can be fully realized by one person, without manual straightening or temporary fixation, which greatly improves work efficiency and reduces labor costs.
