Description

Technical Field

[0001] This utility model relates to the field of construction technology, specifically to an automatic waterproof membrane paving machine for concrete structures that can precisely overlap the edges. Background Technology

[0002] Waterproof membrane is a flexible, rollable building material primarily used in building walls, roofs, tunnels, highways, and landfills to protect against rainwater and groundwater seepage. Large-area installation of waterproof membrane during construction requires automated waterproof membrane pavers to achieve time- and labor-saving benefits.

[0003] Chinese Patent No. CN222513380U describes a waterproof membrane paving machine, belonging to the technical field of waterproof construction equipment. It includes a support plate, a rotating rod, a fixed rod, and a connecting rod. Two vertical plates are fixedly connected to the top of the support plate. First limiting wheels are movably connected to the side of the support plate via pins. Two movable rods and two first electric push rods are movably connected to the bottom of the support plate via pins. A second limiting wheel is movably connected between the two movable rods via pins. The beneficial effect is that by setting the second electric push rods, during the laying of the waterproof membrane, the operator controls the operation of the second electric push rods via an external controller, pushing the connecting rods and the U-shaped frame downwards, causing the extrusion wheel to contact the waterproof membrane and extrude it. This extrusion allows gas remaining on the bonding surface to be expelled before the molten surface of the waterproof membrane solidifies and adheres, thus preventing the formation of cavitation bubbles.

[0004] However, the aforementioned waterproof membrane pavers also have the following drawbacks: when the pavers are laying the membrane, the edges need to be overlapped to improve waterproofing and prevent water seepage at the joints. However, since the aforementioned devices do not have positioning or limiting functions, the operators cannot accurately control the laying path at the overlapped edges, resulting in deviations that affect the laid membrane. Utility Model Content

[0005] The purpose of this invention is to provide an automatic waterproof membrane paving machine that can precisely overlap the edges of concrete structures, in order to solve the problem mentioned in the background art of not having precise edge overlapping construction operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic waterproof membrane paving machine for concrete structures capable of precise edge overlapping, comprising a paving roller, a laser positioning mechanism, a heating roller, and an elastic pressure roller mechanism, wherein the laser positioning mechanism is symmetrically provided at both ends of the paving roller; The laser positioning mechanism includes a red laser, which is fixedly installed on the surface of the back plate, and a slider is fixedly installed on the back of the back plate. The slider and the slide rail are slidably connected, and the slide rail is fixedly installed on the surface of the L-shaped plate. The heating roller is located at one end of the paving roller and is fixedly mounted on the roller shaft together with it; The elastic pressure roller mechanism is located on the rear side of the paving roller and includes a pressure roller and a spring component. The pressure roller is movably mounted on the wheel frame via a wheel axle. A connecting plate is provided above the wheel frame, and a spring component is provided between the connecting plate and the wheel frame.

[0007] Furthermore, the L-shaped plate is provided with multiple threaded holes in an array, and the back plate is fixedly connected to the L-shaped plate by the cooperation of fastening screws with the threaded holes.

[0008] Furthermore, both ends of the roller are mounted on the sheet metal part via bearing seats, and the other side of the sheet metal part is provided with mounting holes.

[0009] Furthermore, the L-shaped plate is fixedly installed on the outside of the sheet metal part by bolts.

[0010] Furthermore, the heating roller and the elastic pressure roller mechanism form a stacking and pressing assembly.

[0011] Furthermore, the spring component is internally fitted with a first limiting post and a second limiting post. The first limiting post is fixedly installed on the surface of the wheel frame, and the second limiting post is fixedly installed on the bottom surface of the connecting plate.

[0012] Furthermore, one side of the connecting plate is fixedly connected to the inner wall of the sheet metal part, and the connection is reinforced by reinforcing ribs.

[0013] Furthermore, the pressure roller adopts a three-layer composite structure, including a steel core layer, a silicone buffer layer, and a wear-resistant layer.

[0014] The beneficial effects of this utility model are: 1. The laser positioning mechanism is used to detect the offset between the edge of the roll material and the baseline of the concrete structure. Personnel can dynamically adjust the direction according to the offset to achieve precise control of the roll material laying path. At the same time, the dynamic adjustment of the position of the laser positioning mechanism can improve the applicability and meet different on-site needs.

[0015] 2. By using the overlapping and pressing components, the bonding strength at the joints is improved. In conjunction with the laser positioning mechanism, the operation stability at the overlapping positions is improved during the laying of the waterproof membrane, thereby increasing its performance in later use.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] Please see Figure 1-3 This utility model provides a technical solution: an automatic waterproof membrane paving machine for concrete structures that can accurately overlap the edges, including a paving roller 1, a laser positioning mechanism 2, a heating roller 3 and an elastic pressure roller mechanism 4. The laser positioning mechanism 2 is symmetrically provided at both ends of the paving roller 1. The paving roller 1 is used for the final connection of the membrane and applies the membrane to the external construction area. More specifically, the laser positioning mechanism 2 includes a red laser 201, which uses a 650nm LDD1040 red laser with a positioning accuracy of ±1mm and a response time of ≤0.1s. The red laser 201 detects the offset between the edge of the roll material and the baseline of the concrete structure. Personnel dynamically adjust the direction based on this offset, achieving precise control of the roll material laying path and thus improving accuracy during edge-overlapping operations.

[0020] In a preferred embodiment, the red laser 201 is fixedly mounted on the surface of the back plate 202, and a slider 203 is fixedly mounted on the back of the back plate 202. The slider 203 and the slide rail 204 are slidably connected. The slide rail 204 is fixedly mounted on the surface of the L-shaped plate 205. Due to the arrangement of the slider 203 and the slide rail 204, the position of the red laser 201 can be adjusted on the L-shaped plate 205 through the back plate 202, thereby improving its applicability and meeting different on-site usage requirements.

[0021] It should be noted that the use of the red laser 201 is existing technology, and its power connection is connected and used with existing pavers.

[0022] Preferably, the heating roller 3 is located at one end of the paving roller 1 and is fixedly mounted on the roller shaft 5. Both ends of the roller shaft 5 are mounted on the sheet metal part 6 through bearing seats, and the other side of the sheet metal part 6 is provided with mounting holes 8. The sheet metal part 6 is used to install bolts embedded in the mounting holes 8 for use on existing pavers. When the roller shaft 5 rotates, the heating roller 3 rotates synchronously with the paving roller 1. The heating roller 3 can heat the overlapping part of the roll material, so that it can be well bonded to the edge of the laid roll material. The heating roller 3 is existing technology.

[0023] L-shaped plate 205 is fixedly installed on the outside of sheet metal part 6 by bolts 7, thereby installing the laser positioning mechanism on sheet metal part 6, which is located in front of roller 5.

[0024] In a preferred embodiment, more specifically, the elastic pressure roller mechanism 4 is disposed on the rear side of the paving roller 1, and includes a pressure roller 401 and a spring element 402. The pressure roller 401 is movably mounted on the wheel frame 403 via a wheel axle 408. A connecting plate 404 is disposed above the wheel frame 403, and the spring element 402 is disposed between the connecting plate 404 and the wheel frame 403. The spring element 402 is internally fitted with a first limiting post 405 and a second limiting post 406. The first limiting post 405 is fixedly installed on the surface of the wheel frame 403, and the second limiting post 406 is fixedly installed on the bottom surface of the connecting plate 404. When the heating roller 3 heats and bonds the roll material at the overlapping area, the pressure roller 401 further enhances the bonding tightness, while the spring element 402 provides an elastic buffering effect, ensuring stable pressing.

[0025] Preferably, one side of the connecting plate 404 is fixedly connected to the inner wall of the sheet metal part 6 and reinforced by the reinforcing rib 407, so that the elastic pressure roller mechanism 4 is fixedly installed on the sheet metal part 6 for use, ensuring that the tight connection effect between them can be improved after the coil is heated.

[0026] Preferably, the pressure roller 401 adopts a three-layer composite structure, including a steel core layer, a silicone buffer layer, and a wear-resistant layer.

[0027] Preferably, the heating roller 3 and the elastic pressure roller mechanism 4 form an edge pressing assembly, which ensures improved bonding strength at the joint. In conjunction with the laser positioning mechanism, this improves the operational stability at the edge position during the laying of the waterproof membrane and enhances its performance in later use. Example

[0028] Please see Figure 2 The L-shaped plate 205 has multiple threaded holes 206 arranged in an array, and the back plate 202 is fixedly connected to the L-shaped plate 205 by fastening screws 207 engaging with the threaded holes 206. Due to the provided slider and slide rail, the laser positioning mechanism has an adjustable displacement function. The fastening screws and threaded holes create a fixed connection, allowing for dynamic adjustment of the laser positioning mechanism's position, improving its applicability and meeting different on-site usage requirements.

[0029] In this embodiment, the following steps are taken: Bolts are inserted into the mounting holes on the sheet metal parts to fix them on the paver, forming the end of the waterproof membrane for paving. In the early stage, the laser positioning mechanism is moved to meet the measurement and positioning requirements. According to the technicians, the fastening screws are matched with the threaded holes to fix its position. The laser positioning mechanism emits light so that the edge of the membrane and the baseline of the concrete structure form a reference line, allowing it to be laid along the line. At this time, the heating roller heats the membrane at the overlapping area, so that the overlapping edge is bonded, and the pressure roller further tightens the connection, thereby completing the overlapping operation.

[0030] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
