Description

Technical Field

[0001] This utility model relates to the field of building construction structure technology, specifically a tooling for precise positioning of protective fence lines. Background Technology

[0002] With the rapid development of high-speed railway construction, under-bridge protective fences, as key facilities for ensuring traffic safety and isolating illegal intrusion, directly affect the safety of the railway line and the urban landscape due to their construction quality. Traditional under-bridge protective fence construction mainly uses a combination of string line positioning and wooden formwork support, which has the following technical defects:

[0003] 1. Low accuracy of line control: Relying on manual line positioning, it is easily affected by terrain undulations and construction disturbances, resulting in large deviations in the verticality of the fence posts and uneven overall line, making it difficult to meet the acceptance standards of smoothness and straightness.

[0004] 2. Unstable foundation construction quality: The wooden formwork has insufficient rigidity and is prone to deformation during the erection process, resulting in dimensional errors in the concrete foundation. In addition, it has a low turnover rate, increasing material waste.

[0005] 3. Low efficiency: It takes 5 days to construct every 15 foundation columns. The manual adjustment of verticality and alignment is time-consuming and labor-intensive, making it difficult to meet the time requirements of large-scale construction.

[0006] 4. Poor adaptability: The existing wooden formwork combined with steel pipe reinforcement fails to provide proper positioning in complex geological conditions such as pits and slopes, resulting in excessive gaps between the fence and the ground and insufficient protection height.

[0007] Therefore, a precision positioning fixture for protective fence lines is needed to improve the above-mentioned problems. Utility Model Content

[0008] The purpose of this invention is to provide a precision positioning fixture for the linear shape of protective fences to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A precision positioning fixture for a protective fence includes a support template body, the support template body includes several side plate assemblies, adjacent side plate assemblies are assembled by connecting parts, a positioning component is provided at the upper end of the support template body, a column is provided within the positioning component for limiting, and several support members are provided on the side of the column.

[0011] The side plate assembly includes several stainless steel side plates, each of which is provided with a mating structure, and the adjacent stainless steel side plates are mated together by the mating structure.

[0012] Furthermore, angle steel is fixedly connected to both the upper and lower ends of the stainless steel side plate, and several reinforcing plates are fixedly connected between the angle steel at the upper and lower ends.

[0013] Furthermore, the docking structure includes a groove formed on the upper end of the angle steel and a protrusion formed on the lower surface of the lower end of the angle steel, the protrusion engaging with the groove.

[0014] Furthermore, each angle steel has a set of insertion holes at both ends, and the ends of the angle steel at adjacent upper and lower ends are connected by inserting a connecting rod b.

[0015] Furthermore, several connecting blocks are fixedly connected to the sides of the stainless steel side plates, and each connecting block has an opening in the middle. Connecting parts are provided between the connecting blocks of adjacent sides of the stainless steel side plates.

[0016] Furthermore, the connector includes connector a, both ends of which are fixedly connected to insert rods, which are inserted into the middle of the connector block.

[0017] Furthermore, the positioning assembly includes a set of positioning rods, the ends of which are fixedly connected to the stainless steel side plates on both sides by bolts, and a positioning part is provided in the middle of the adjacent sides of the two positioning rods.

[0018] Furthermore, the positioning part includes two sets of angle steel plates, and the two sets of angle steel plates are respectively fixedly connected to the two positioning rods.

[0019] Furthermore, a total of four support members are provided, which respectively provide limiting support for the four sides of the column;

[0020] The support component includes a steel clip that mates with the side of the column, and a diagonal brace is fixedly connected to the side of the steel clip.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This utility model uses the combination of positioning components and support components to limit and support the four sides of the column, avoiding the influence of terrain undulations and construction disturbances on traditional manual line positioning, significantly improving the verticality of the column and the smoothness of the overall line, and effectively meeting the acceptance requirements of smooth and straight high-speed railway protective fence.

[0023] 2. In this utility model, stainless steel side plates are used to replace traditional wooden formwork. Combined with the structural design of angle steel and reinforcing plates, the rigidity and deformation resistance of the formwork are greatly improved, avoiding the dimensional errors of the concrete foundation caused by the deformation of the formwork during the erection process. At the same time, the stainless steel material can be reused multiple times, reducing material waste.

[0024] 3. The modular side panel assembly and positioning assembly of this utility model have precise positioning functions, which simplify the tedious steps of manually adjusting verticality and alignment, shorten the construction cycle of a single foundation, and are more suitable for the construction period requirements of large-scale construction of protective fences under high-speed railway bridges. The docking structure of the stainless steel side panel and the design of adjustable support components effectively solve the problem of positioning failure of traditional wooden molds under complex geological conditions such as pits and slopes, ensuring that the gap between the fence and the ground and the protection height meet the standards and improving the protection safety.
