Description

Technical Field

[0001] The utility model relates to the technical field of waterproof construction, in particular to a waterproof construction device for a subway station. Background Art

[0002] In the construction of subway stations, waterproofing membranes are used as a key material, mainly in building walls, roofs, tunnels, roads and landfills. Waterproofing membranes are a flexible building material product that can be rolled into a roll to effectively prevent leakage from external rainwater or groundwater. As the first barrier to waterproofing the entire project, waterproofing membranes play a vital role in construction.

[0003] However, there are some problems in the current construction process of waterproof membranes. When workers are carrying out membrane construction, they need to use a spray gun to spray and compact the membrane. This process requires high skills and experience from workers, because the angle and distance of spraying are completely dependent on the workers' control. If the control is improper, it is easy to cause excessive spraying and affect the construction quality. At the same time, it is difficult for workers to ensure that the membrane is tightly adhered by compacting it with their feet, which further affects the construction quality. Therefore, we need to find more effective solutions to improve the construction quality and efficiency of waterproof membranes.

[0004] Chinese Patent 202320473710.0 (application number) discloses a roll waterproofing construction device, which achieves the goal of one-person operation by integrating the three processes of roll spreading and roll compaction, significantly improving the construction quality. However, this device is difficult to adapt to different subway tunnel sites when moving. Due to the difference in the width of the construction ground, the fixed wheelbase device cannot work normally in a narrow environment, resulting in its application scope being limited. In addition, the current spraying operation still relies on a handheld gun, which increases the construction time. Utility Model Content

[0036] Two slide grooves 3 are arranged on the bottom plate 1, and a moving block is arranged on the top of the adjusting plate 4, and the moving block is used to move in the slide groove 3; the two slide grooves 3 are parallel to each other, and one adjusting plate 4 is arranged corresponding to one slide groove 3; and a roller 5 is installed on the adjusting plate 4;

[0037] The spray roasting device comprises a gas tank 9 and a nozzle, a hose 10 is arranged between the gas tank 9 and the nozzle; the gas tank 9 is arranged and fixed on the bottom plate 1, a valve is arranged on the gas tank 9, and the valve is connected to the hose 10.

[0038] The waterproof construction device disclosed in the utility model includes a walking mechanism and a spraying device. The walking mechanism is composed of a base plate 1 and a walking adjustment structure, and the walking adjustment structure is connected to the adjustment plate 4 through a bidirectional screw 6. A slide groove 3 is provided on the base plate 1, and the top moving block of the adjustment plate 4 can slide in the slide groove 3, so that the adjustment plate 4 can move laterally on the base plate 1. Through the above structure, the spacing of the rollers 5 can be stably adjusted, ensuring that the waterproof construction device has good site adaptability and can be walked on a relatively narrow ground for construction.

[0039] The spraying device is composed of a gas tank 9 and a nozzle. The gas tank 9 is fixed on the bottom plate 1 and connected to the nozzle through a hose 10. A valve is provided on the gas tank 9 to control the gas flow in the gas tank 9. The device can be used for waterproofing construction in a subway station, which is convenient and fast.

[0040] In a preferred embodiment, after the wheel spacing is adjusted, the spacing between the moving blocks on the top of the adjusting plate 4 is also shortened, so the moving blocks on both sides can move left and right together. Although the requirement of narrow ground construction is met, the position of the bottom plate 1 or the roller 5 is not easy to determine. Therefore, in order to solve this technical problem, the roller 5 is always located on both sides of the center line of the bottom plate 1, and a limit mechanism is set.

That is, a threaded section is provided on the guide rod 13, and a nut is provided at the upper and lower positions of the top plate respectively. After adjusting the position of the guide rod 13, the position of the guide rod 13 is fixed by the nut.

[0047] In a preferred embodiment, if Figure 4 As shown, a winding roller 15 is provided between the first side plate and the second side plate to facilitate the winding of the waterproofing membrane 2 .

[0048] In traditional construction, a handheld torch is required to spray the coiled material, which increases construction time and is inconvenient to operate. Figure 5 As shown, an auxiliary moving rod is arranged between the first side plate and the second side plate, and the auxiliary moving rod includes a slide rod 18 and a reciprocating screw rod 16. The slide rod 18 and the reciprocating screw rod 16 are arranged in parallel. A slider 17 is arranged on the reciprocating screw rod 16, and the slider 17 is threadedly connected with the reciprocating screw rod 16 to realize the reciprocating motion of the slider 17; a through hole that cooperates with the slide rod 18 is also arranged on one side of the slider 17. Preferably, a motor 19 is arranged at the end of the reciprocating screw rod 16, and the motor 19 is installed next to the first side plate or the second side plate. The motor 19 is used to drive the reciprocating screw rod 16 to rotate.

[0049] In a preferred embodiment, the slider 17 is provided with an air supply channel, one end of the air supply channel is connected to the hose 10, and the other end of the air supply channel is connected to the (stereotyped or adjustable angle) serpentine tube, and a nozzle is provided at the end of the serpentine tube.

The serpentine tube has a bendable effect, which is convenient for adjusting the angle and distance of the nozzle. In another embodiment, a clamping device can be provided on the slider 17, and the clamping device is used to clamp the nozzle or the hose 10 near the nozzle.

[0050] Preferably, an armrest 11 is fixedly connected to the base plate 1 to facilitate pushing the device.

[0051] Furthermore, in order to limit the position of the waterproof coiled material 2, threaded sections are provided at both ends of the winding roller 15. Nuts and limit plates are provided on the threaded sections, and the limit plates can be sleeved on the threaded sections or threadedly connected with the threaded sections.

The waterproof construction device for subway stations is provided with the slide groove 3, the adjustment plate 4, the roller 5 and the bidirectional screw 6. During use, when a narrow construction ground is encountered in a subway tunnel, the bidirectional screw 6 can be directly rotated forward. After the adjustment plates 4 are subjected to the thread force of the bidirectional screw 6, they can approach each other, thereby reducing the distance between the rollers 5, making it easier for the construction device to move and construct on a narrow road surface. After the bidirectional screw 6 is rotated in the opposite direction, the two groups of adjustment plates 4 can be driven to move away from each other to increase the distance between the rollers 5, thereby greatly increasing the adaptability of the construction.
