Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a tool for shaping grooves in civil engineering and its construction method. Background Technology

[0002] The prefabricated formwork for concrete trenches is a specialized molding die for concrete trench pouring. It is primarily made of steel plates and high-strength composite panels, prefabricated in a factory. It can be integrally molded according to the trench specifications in the construction drawings, allowing for simple and quick on-site assembly. After the concrete is poured, the trench has uniform dimensions and neat, straight edges, effectively avoiding dimensional deviations caused by manual formwork and ensuring the accuracy of trench construction.

[0003] Currently, the standardized formwork used in existing civil engineering recess construction requires on-site assembly of multiple panels, making it difficult to control the gaps between the panels. The formwork cavity lacks supporting reinforcement structures, leading to uneven stress on the side walls after concrete pouring, which easily causes bulging and deformation, resulting in recesses exceeding size limits and uneven wall surfaces. Subsequent repairs are labor-intensive and costly, resulting in low construction efficiency and difficulty in controlling the final product quality.

[0004] Therefore, developing a civil engineering groove shaping tool that can effectively improve construction efficiency is one of the important problems that needs to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide a tool for shaping grooves in civil engineering, so as to solve the problem of low construction efficiency caused by the need to assemble multiple plates on site in the construction process in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a civil engineering groove shaping tool, including a groove template, wherein the groove template is a three-sided enclosed structure with open sides, and a grid-like support component is provided on its three inner side walls, wherein the grid-like support component includes a plurality of vertical reinforcing ribs and a plurality of horizontal reinforcing ribs arranged in an alternating manner;

[0007] The groove template is symmetrically provided with positioning components on both sides. The positioning components include ear plates, limiting rods and fixing nuts. The ear plates are fixed to the outer side wall of the groove template. The ear plates have mounting holes. The limiting rods slide through the mounting holes. One end of the limiting rod has a stop part that abuts against the outer surface of the ear plate. The other end of the limiting rod has a threaded section. The fixing nut is threadedly engaged with the threaded section for fixed connection with the civil engineering reinforcement cage.

[0008] Furthermore, the inner wall of the groove template is provided with several positioning rods. The positioning rods are horizontally arranged and vertically spaced. The two ends of the positioning rods are respectively fixedly connected to the intersection of the vertical reinforcing ribs and the horizontal reinforcing ribs on both sides.

[0009] Furthermore, the overall length of the limiting rod is greater than the depth of the groove template.

[0010] Furthermore, the fixing nut has an internal thread structure, and the fixing nut is used to be pre-welded and fixed to the civil engineering steel cage, and to be screwed and tightened with the threaded section of the limiting rod.

[0011] Furthermore, the groove template, vertical reinforcing ribs, horizontal reinforcing ribs, and ear plates are manufactured using an integrated molding process.

[0012] This application also provides a construction method for a civil engineering groove shaping tool, wherein the construction method using the aforementioned civil engineering groove shaping tool includes the following steps:

[0013] S1. Place the groove template vertically in the predetermined groove position of the civil construction, and adjust the position of the template to make it precisely aligned with the design and construction marking line;

[0014] S2. Weld the fixing nuts to the corresponding positions of the civil engineering reinforcement cage in a vertical straight line to ensure that all fixing points are on the same vertical line.

[0015] S3. Slide the limiting rod into the mounting hole of the ear plate, so that the threaded section of the limiting rod engages with the thread of the fixing nut and tightens it. Complete the positioning and fixing of both sides of the groove template in sequence to ensure that the template is vertical and has no tilt.

[0016] S4. Pour concrete into the groove template, where the grid support components and positioning rods work together to resist the lateral pressure of the concrete.

[0017] S5. After the concrete has solidified and reached the required strength, loosen the connection between the limiting rod and the fixing nut in the reverse direction, and remove the groove template upwards to complete the groove forming operation.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention uses a grid-like support component set on the inner sidewall of the groove template. The overall reinforced skeleton is formed by staggered vertical and horizontal reinforcing ribs, and is supplemented by horizontal positioning rods to provide lateral support to the two sidewalls. This greatly improves the deformation resistance and structural rigidity of the template sidewalls, fundamentally eliminating the problems of mold expansion and deformation during concrete pouring, and ensuring the accurate forming dimensions of the groove.

[0020] 2. This invention achieves a firm connection between the template and the civil engineering reinforcement cage through an adjustable positioning assembly consisting of ear plates, limiting rods, and fixing nuts. At the same time, the sliding adjustment and threaded fastening of the limiting rods ensure the vertical installation of the template, effectively avoiding displacement and tilting problems during the pouring process and improving the installation positioning accuracy.

[0021] 3. The groove template, reinforcing ribs and ear plates of the present invention are manufactured using an integrated molding process, with no splicing gaps, uniform overall stress, and higher structural strength; at the same time, the outer surface of the template is smooth, so that the inner wall surface of the groove after casting has a high degree of smoothness, with no obvious seams and defects, eliminating the need for manual secondary grinding and repair, greatly simplifying the later construction process and effectively improving construction efficiency.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1

[0029] like Figures 1-4 This invention provides a tool for shaping grooves in civil engineering, including a groove template 1. The groove template 1 has an open side structure and integrates a reinforcing support component inside. The groove template 1 is equipped with precision positioning components on both sides, which can realize the rapid shaping and casting of civil engineering grooves. It solves the construction pain points of traditional groove shaping tools, such as easy mold expansion and deformation, poor positioning accuracy, low forming quality, and large amount of subsequent repairs, and effectively improves the construction efficiency and forming accuracy of civil engineering grooves.

[0030] Specifically, to address the problem of insufficient structural strength in traditional civil engineering groove shaping tools, which easily leads to bulging and sidewall deformation under lateral pressure during concrete pouring, resulting in excessive groove dimensional deviations and substandard forming quality, the civil engineering groove positioning tool of this invention is equipped with a grid-like multi-reinforcement support component. Multiple sets of vertically spaced vertical reinforcing ribs 2 are fixedly installed on the inner wall of the groove template 1, along with multiple sets of horizontally spaced horizontal reinforcing ribs 21. The vertical and horizontal reinforcing ribs 2 and 21 are staggered to form an overall grid-like reinforcing skeleton, significantly improving the deformation resistance and structural rigidity of the template sidewalls. Several positioning rods 22 are also vertically spaced on the inner wall of the groove template 1. The two ends of each positioning rod 22 are fixedly connected to the vertical and horizontal reinforcing ribs 2 and 21 on both sides, respectively, providing additional lateral support to the sidewalls of the groove template 1. This further enhances the overall lateral pressure resistance of the template, effectively resisting the impact and lateral pressure during concrete pouring, fundamentally eliminating bulging and deformation problems, and ensuring accurate groove forming dimensions.

[0031] To address the problems of cumbersome installation and positioning, weak connection to the reinforcing cage, and easy displacement and tilting during pouring, leading to large deviations in the verticality of the groove, traditional groove shaping tools are designed with an adjustable precision positioning component. Two ear plates 3 are symmetrically fixed on both sides of the groove template 1. Each ear plate 3 has several vertically mounted limiting rods 31. The ear plates 3 have holes through which the limiting rods 31 can slide freely within the ear plates 3 to adjust their installation position. The tail end of each limiting rod 31 has a threaded groove, on which an internally threaded retaining block 32 is screwed. The overall length of the limiting rod 31 is greater than the depth of the groove template 1, accommodating the positioning needs of grooves of different depths. By pre-welding the internally threaded retaining block 32 to the reinforcing cage and then using the sliding adjustment and threaded connection of the limiting rod 31, a secure connection between the template and the reinforcing cage can be achieved, ensuring the template is installed vertically and effectively preventing displacement and tilting during pouring, thus improving installation positioning accuracy.

[0032] To further enhance the overall structural stability and construction quality of the tool, and reduce subsequent manual repair procedures, the groove template 1, vertical reinforcing ribs 2, horizontal reinforcing ribs 21, and ear plates 3 are manufactured using a one-piece molding process. The one-piece molding structure has no seams, resulting in uniform stress distribution and higher structural strength, further enhancing the tool's resistance to deformation and its service life. Simultaneously, the outer surface of the groove template 1 is smoothed, ensuring a high degree of smoothness on the inner wall surface of the cast groove, with no obvious seams or defects. This eliminates the need for secondary manual grinding and repair, significantly simplifying the subsequent construction process and effectively improving construction efficiency.

[0033] The working principle is as follows: During construction, the groove template 1 is first placed vertically at the predetermined groove position in the civil construction, and the template position is adjusted to precisely align with the design construction lines. Then, the internally threaded retaining blocks 32 are welded and fixed to the corresponding positions in the civil reinforcement cage in a vertical straight line, ensuring that all retaining points are on the same vertical line, providing a reference for the vertical installation of the template. The limiting rod 31 is slid into the corresponding mounting hole of the ear plate 3, so that the threaded groove at the end of the limiting rod 31 engages with the internally threaded retaining block 32, thus completing the positioning and fixing of both sides of the groove template 1, ensuring that the template is vertical and without tilt. After the template is fixed, the internally staggered vertical reinforcing ribs 2 and horizontal reinforcing ribs 21 form the main support for the three side walls of the template, and multiple positioning rods 22 form auxiliary support for the two side walls, jointly resisting the lateral pressure during concrete pouring and preventing deformation due to bulging. After the concrete has solidified and reached the required strength, the connection between the limiting rod 31 and the internally threaded retaining block 32 is loosened in the reverse direction, and the groove template 1 is removed upwards to complete the groove forming operation. Because the surface of the groove template 1 is smooth and flat, the inner wall of the groove after molding has a high degree of smoothness, eliminating the need for secondary manual repairs and making construction convenient and efficient.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
