Description

Technical Field

[0001] The invention belongs to the technical field of tunnel waterproofing and drainage construction, and in particular relates to a simple hot-melt gasket positioning tool. Background Art

[0002] Tunnel waterproofing hot-melt rings are a material used in tunnel waterproofing projects, typically made from polymers such as EVA (ethylene-vinyl acetate copolymer) and PE (polyethylene). Their primary function is to secure the waterproofing sheet to the tunnel wall via heat-melt welding during installation, creating a sealed waterproof layer and preventing groundwater infiltration. Installation of the hot-melt rings requires specialized hot-melt welding equipment, which heats the rings to a specific temperature to fuse them to the surface of the waterproofing sheet. During installation, the heating temperature and welding time of the hot-melt rings must be carefully controlled to ensure weld quality. Special attention must also be paid to the placement and spacing of the hot-melt rings to ensure the integrity and reliability of the waterproofing layer. Traditionally, hot-melt rings for tunnel waterproofing sheets are positioned manually, resulting in poor alignment and low efficiency, directly impacting tunnel construction progress. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and proposes a simple hot-melt gasket positioning tool.

[0004] To achieve the above object, the technical solution created by the present invention is implemented as follows:

[0005] A simple hot-melt gasket positioning tool comprises a long positioning arm and a short positioning arm, which are hinged in the middle by an axis-like part. The long positioning arm is provided with a handle on the side different from the short positioning arm, and the plane where the long positioning arm is located is parallel to the plane where the short positioning arm is located. The long positioning arm is provided with a limit block for limiting the vertical state of the short positioning arm and the long positioning arm, and the limit block is provided on the long positioning arm; the two ends of the long positioning arm are respectively provided with long arm claws on the side different from the handle, and the two ends of the short positioning arm are respectively provided with short arm claws on the side different from the handle, and the ends of the long arm claw and the short arm claw are both provided with support columns, and the connection between the support column on the long arm claw and the long arm claw, and the connection between the support column on the short arm claw and the short arm claw, both form steps.

[0006] Furthermore, each support column adopts a telescopic structure.

[0007] Furthermore, the support column is threaded onto the long arm claw / short arm claw. By changing the screwing length of the support column and the long arm claw / short arm claw, the distance between the support column and the long positioning arm / short positioning arm can be adjusted, which has strong adaptability to on-site working conditions, high flexibility and easy adjustment.

[0008] Furthermore, the shaft parts include hinge shafts or bolts.

[0009] Furthermore, the handle is in a U-shape, and both ends of the handle are welded and fixed to the long positioning arm.

[0010] Furthermore, the handle is formed by bending steel bars.

[0011] Furthermore, the long positioning arm and the short positioning arm are both made of square tubes.

[0012] Furthermore, a connecting hole is provided on the limit baffle, and a socket is provided on the short positioning arm corresponding to the connecting hole. When the short positioning arm is rotated counterclockwise to a position perpendicular to the long positioning arm, the socket corresponds to the connecting hole. At this time, by inserting a screw into the socket of the short positioning arm and screwing the end of the screw into the connecting hole, the short positioning arm and the long positioning arm can be stably maintained in a perpendicular relationship with each other.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] This tool can effectively reduce the time and labor of a large amount of manual marking and measuring distances, is easy to operate, and realizes rapid construction. It solves the problem of slow construction of hot-melt gaskets in tunnel waterproofing and drainage systems, and at the same time effectively speeds up the construction progress and quality of hot-melt gaskets in the secondary lining waterproofing and drainage system. The tool is simple and convenient to use and operate, simple to process, and can be reused, reducing the number of construction personnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0024] A simple hot melt gasket positioning tool, such as Figures 1 to 4 As shown, it includes a long positioning arm 1 and a short positioning arm 2, which are hinged in the middle by a shaft-like part 3. A handle 4 is provided on the side of the long positioning arm that is different from the short positioning arm. The plane where the long positioning arm is located is parallel to the plane where the short positioning arm is located. When the short positioning arm is rotated counterclockwise with the shaft-like part as the center (with the handle side as the observation direction) to a position perpendicular to the long positioning arm, a limit block 5 is provided on the long positioning arm at the corresponding position, and the limit block is welded and fixed to the long positioning arm.

[0025] The long positioning arm is provided with a long arm claw 6 at both ends on the side different from the handle, and the short positioning arm is provided with a short arm claw 7 at both ends on the side different from the handle. The ends of the long arm claw and the short arm claw are both provided with a support column 8. The connection between the support column on the long arm claw and the long arm claw, and the connection between the support column on the short arm claw and the short arm claw, both form a step 9. The end of the support column is set to a cone end, which can be more stably maintained on the surface of the geotextile.

[0026] In one optional embodiment, each support column utilizes a telescopic structure. In another optional embodiment, the support column is threaded onto the long arm claw / short arm claw. By varying the length of engagement between the support column and the long arm claw / short arm claw, the distance between the support column and the long positioning arm / short positioning arm can be adjusted, providing strong adaptability to on-site working conditions and high flexibility. By conveniently adjusting the support column, the distance between the end of the support column and the step can be tailored to the thickness of the hot-melt gasket, effectively confining the hot-melt gasket to the support column, i.e., confining the hot-melt gasket between the step and the secondary lining waterproofing board.

[0027] For example, the shaft-like parts include hinges or bolts. The handle is in the shape of a U, with both ends welded to the long positioning arm. The handle is made of bent steel bars. Both the long and short positioning arms are made of square tubes. Locally sourced materials are readily available, making it easy to manufacture, low-cost, and reusable.

[0028] The stopper is provided with a connection hole, and a corresponding insertion hole is provided on the short positioning arm. When the short positioning arm is rotated counterclockwise to a perpendicular position with the long positioning arm, the insertion hole aligns with the connection hole. At this time, by inserting a positioning screw 10 into the insertion hole of the short positioning arm and screwing the end of the positioning screw into the connection hole, the short positioning arm and the long positioning arm can be stably maintained in a perpendicular relationship with each other.

[0029] To use the fixture, simply rotate the short locating arm 90° (i.e., rotate the short locating arm to a perpendicular position with the long locating arm), use the stopper to limit the position, and secure with the positioning screws. During construction, first draw a horizontal ink line on the lowest layer of geotextile in the secondary lining side wall to ensure the reference position of the hot-melt gasket. Then use this positioning fixture to position the reference hot-melt gasket at the ink line. After aligning one claw of the fixture with the hot-melt gasket at the reference position, the corresponding positions of the other end claws are also hot-melt points. Then, use a nail gun to install the hot-melt gasket.

[0030] The present invention provides a handheld tool for positioning hot-melt gaskets in tunnel drainage systems. The tool is simple to manufacture and can be fabricated by electric welding on the construction site. The tool is simple, lightweight, flexible, and easy to store. Operators can operate it with one hand, achieving rapid construction. The tool also provides excellent positioning results, resulting in neat and aesthetically pleasing lines. The use of this tool effectively reduces the time required for manual line drawing and distance measurement, thereby achieving simple, easy-to-operate, and rapid construction. This solves the problem of slow construction of hot-melt gaskets in tunnel drainage systems and effectively accelerates the construction progress and quality of hot-melt gaskets in secondary lining drainage systems. The tool is simple and convenient to use and operate, simple to process, and reusable, reducing the number of construction personnel.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
