Description

Technical Field

[0001] This utility model belongs to the field of building construction, specifically relating to a segmented template based on a water ditch cable trough. Background Technology

[0002] In tunnel construction, drainage ditches and cable trenches are indispensable ancillary works, and their appearance quality directly affects the overall image of the tunnel, thus requiring high construction standards. As an ancillary project, drainage ditches and cable trenches are generally constructed as the final step in the tunnel construction process, starting in the later stages, resulting in significant pressure on the construction schedule. Therefore, the construction quality and efficiency of drainage ditches and cable trenches are particularly important in the later stages of tunnel construction.

[0003] Traditional modular steel formwork processes have many shortcomings, such as requiring a large amount of manual labor, unstable formwork reinforcement, low construction efficiency, and poor quality. In contrast, the trench and cable trough formwork trolley provided by CN214196337U has advantages such as simple and precise positioning, convenient operation, high degree of mechanization, low formwork wear, and aesthetically pleasing concrete pouring quality. Therefore, the trench and cable trough formwork trolley has been widely promoted and applied throughout the country.

[0004] like Figure 1 The trolley for cable trenches mainly consists of a walking system, a lifting cylinder 11 for moving the walking system, and trench formwork (including trench formwork 9, cable trench formwork 10, and side formwork 8). However, in the actual construction of cable trenches, due to the pressure of the construction period and the slow increase in concrete strength, demolding is often carried out before the concrete 1 reaches the critical strength required by the specifications. At this time, the edges of the concrete do not have sufficient shear resistance and are damaged.

[0005] Secondly, due to the limited clearance of the tunnel cross-section, the sidewalls or central partitions of the trench are generally designed to be thin, typically only 10-15cm, which is not conducive to demolding. Furthermore, the formwork trolley for the cable trench uses a hydraulic system for demolding. The formwork is heavy, and the demolding process is affected by the eccentric design flaw, which easily causes the concrete sidewalls to be squeezed during demolding, leading to concrete cracking.

[0006] Thirdly, the template trolley is conventionally designed. Both the drainage ditch template 9 and the cable trough template 10 are integral. The adhesion between the concrete and the template is relatively large. Moreover, the cross-sectional dimensions of the drainage ditch are usually smaller than those of the cable trough. Therefore, the adhesion between the two ditches and the template is inconsistent during the demolding process. When the lifting cylinder 11 is used for demolding, it is easy to damage the concrete.

[0007] In conclusion, resolving the quality issue of chipped edges and corners during the demolding of concrete in cable trenches is an urgent and important task. Utility Model Content

[0008] The purpose of this utility model is to overcome the defects in the prior art and provide a segmented template based on a water ditch cable trough.

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

[0010] A modular template based on a water ditch and cable trough includes a water ditch template and a cable trough template. Each water ditch template and cable trough template independently includes two side templates positioned on the left and right sides, ear plates mounted on the side templates, and screws connecting the two ear plates. The two side templates form an integral box-type template structure. A gap is provided between the tops of the two side templates. All side templates are made of steel, assembled by cutting and welding steel plates.

[0011] One end of the lead screw is provided with a rotating handle.

[0012] The ear plate is provided with bolt holes; the lead screw passes through the bolt holes on the two ear plates on the left and right sides.

[0013] The water trench template, the cable trench template, and the side template are all equipped with lifting cylinders.

[0014] A crossbeam is installed between the lifting cylinders on the water trench template, the cable trench template, and the side template.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The technical solution of this application fully considers the operability and convenience of achieving rapid demolding of the cable trough formwork trolley under the condition of insufficient concrete strength in the trench. Before using the lifting cylinder for demolding, a lead screw is used for pre-demolding, eliminating the uncertainty of ensuring concrete quality during demolding, enhancing the applicability of the cable trough formwork trolley, ensuring the construction quality of the trench concrete, ensuring aesthetic appearance, and improving the overall image of the tunnel. The device has a clear and simple structural force principle, a high safety factor, flexible and quick installation, strong practicality, and high controllability. The entire device is welded, not easily damaged, has good integrity, is lightweight and durable, and is suitable for single-person operation. It can be operated by a single person, reducing labor input and demolding time, and can be mass-produced and put into use. Attached Figure Description

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and preferred embodiments.

[0020] Figure 2 A modular template based on a water ditch and cable trough is shown, including a water ditch template and a cable trough template; the water ditch template and the cable trough template each independently include two side templates placed on the left and right sides, ear plates 6 set on the side templates, and screws 7 connecting the two ear plates; one end of the screw is provided with a rotating handle.

[0021] The two side templates on the left and right sides of the water trench template are the left side plate 2 and the left side plate 4 of the water trench, respectively; the two side templates on the left and right sides of the cable trench template are the left side plate 4 and the left side plate 4 of the cable trench, respectively.

[0022] The two side templates form an integral hollow box-type template structure; a gap is provided between the tops of the two side modules to facilitate moving the two side templates closer or further apart by rotating the lead screw.

[0023] The ear plate is provided with bolt holes; the lead screw passes through the bolt holes on the two ear plates on the left and right sides.

[0024] Lifting cylinders 11 are provided on the water trench template, the cable trough template, and the side template 8. A crossbeam 12 is provided between the lifting cylinders provided on the water trench template, the cable trough template, and the side template.

[0025] The technical solution of this device divides the trench template 9 into a left side plate 2 and a right side plate 3, and the cable trough template 10 into a left side plate 4 and a left side plate 5. By setting a pin lug plate 6 and a screw rod 7 on the top of the side template, the screw rod 7 is tightened before starting the lifting cylinder 11 to separate the side template from the concrete side wall, usually by only 1 to 3 mm. As a preferred embodiment, a crossbeam 12 is set between the lifting cylinder 11 and the trench template to make it more integrated and the lifting process more balanced.

[0026] The design principle of this device is as follows: The two side templates of the trench formwork are connected by a pin, lug plate 6, and screw rod 7. Tightening the screw rod 7 inward causes the two side templates to move closer together, achieving the first demolding of the template from the concrete sidewall. Tightening the screw rod 7 outward causes the two sections to separate, restoring the template to its original design state. The crossbeam 12 enhances the overall integrity of the steel formwork and ensures a consistent lifting speed, achieving the second demolding of the template from the concrete. This segmented formwork design based on a trench cable trough trolley divides the demolding process into two stages, effectively reducing template adhesion and offering a simple and convenient process.

[0027] The operating procedure for this device is as follows: the template trolley is positioned, the template positioning is checked, the trench concrete 1 is poured, the screw rod 7 is turned, the two side templates move closer to the middle, the two sides of the side templates separate from the concrete 1, the lifting cylinder 11 is started, and the demolding is completed.

[0028] In summary, the technical solution of this application fully considers the operability and convenience of achieving rapid demolding of the cable trough formwork trolley under the condition of insufficient concrete strength in the trench. Before using the lifting cylinder for demolding, a lead screw is used for pre-demolding, eliminating the uncertainty of ensuring concrete quality during demolding, enhancing the applicability of the cable trough formwork trolley, ensuring the quality of trench concrete construction, ensuring aesthetic appearance, and improving the overall image of the tunnel. The device has a clear and simple structural force principle, a high safety factor, flexible and rapid installation, strong practicality, and high controllability. The entire device is welded, making it less prone to damage, with good integrity, lightweight and durable, suitable for single-person operation. It allows for single-person operation, reducing manpower input and demolding time, and can be mass-produced and put into use.

[0029] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
