Description

Technical Field

[0001] The invention relates to the technical field of building waterproof construction, in particular to a device for laying and fixing thermoplastic polyolefin waterproof coiled materials for construction projects. Background Art

[0002] Polyolefin waterproofing membrane usually refers to waterproofing materials based on thermoplastic polyolefin TPO, which is a high-performance product in modern building waterproofing projects. TPO material has strong resistance to UV rays, high temperature and low temperature through molecular structure design. It can be exposed to harsh environments for a long time without becoming brittle or degrading, and has a service life of more than 20 years. It is mainly used for building roof waterproofing and is suitable for large-scale roofing projects such as industrial plants, public buildings, and commercial complexes. It is especially suitable for light steel structure roofs. Polyolefin waterproofing membrane needs to be laid and fixed with the help of special equipment.

[0003] For example, the Chinese patent "CN114961144A A device for laying and fixing waterproofing membranes for construction projects" includes a base and a mounting sleeve, and also includes: a membrane transmission mechanism, which is installed at the left end between a pair of third support frames; a hot melt baking mechanism, which is arranged on the right side of the membrane transmission mechanism; an extrusion laying mechanism, which is installed on the mounting frame; through the cooperation between the membrane transmission mechanism, the hot melt baking mechanism and the extrusion laying mechanism, one end of the waterproofing membrane wound on the mounting sleeve can be driven for laying and transmission, and the waterproofing membrane that is laid and driven can be hot melt baked, and after the hot melt baking is completed, it can be extruded and laid, so as to realize the automatic laying and fixing of the waterproofing membrane, which is simple to operate and not prone to laying misalignment.

[0004] In actual applications, the existing thermoplastic polyolefin waterproof membrane laying and fixing device always maintains a constant pressure on the polyolefin waterproof membrane, and cannot be adaptively adjusted according to the characteristics of different types of polyolefin waterproof membranes. Due to the differences in thickness of various types of polyolefin waterproof membranes, if this constant pressure method is used during laying construction, it is easy to cause the polyolefin waterproof membrane to not fit tightly against the building surface, and it is very likely that quality problems such as bulging and separation will occur between the membrane and the building surface, seriously affecting the waterproof effect and service life. Summary of the Invention

[0005] The present invention relates to a device for fixing and laying thermoplastic polyolefin waterproofing membranes for construction projects. The device can adjust the lifting and lowering of a lifting crossbar according to the thickness of the polyolefin waterproofing membrane, change the distance between the lifting crossbar and a force-bearing movable frame, thereby changing the thrust applied by a spring A to the force-bearing movable frame, increasing or reducing the pressure on the polyolefin waterproofing membrane, and making the polyolefin waterproofing membrane come into close contact with the building surface under the uniform pressure applied by a pressure roller, thereby better meeting the requirements for laying polyolefin waterproofing membranes of different thicknesses.

[0006] The first aspect of the present invention provides a device for laying and fixing thermoplastic polyolefin waterproof membrane for construction engineering, specifically comprising: a main pushing frame, a supporting wheel, a supporting shaft, a force-bearing movable frame, a pressure roller, a lifting cross bar, a debugging arch frame, a nut, an upper pulling frame and a bolt; support wheels are installed on both sides of the main pushing frame, and connecting grooves are provided on both sides of the front end of the main pushing frame, and the connecting grooves are connected to the supporting rotating shaft, and the polyolefin waterproof membrane is sleeved on the outside of the supporting rotating shaft; the bottom of the main pushing frame is connected to the force-bearing movable frame, and two pressure rollers are installed at the bottom of the force-bearing movable frame; the lifting cross bar is connected inside the main pushing frame, and the supporting shaft is connected to the bottom of the lifting cross bar; the top of the main pushing frame is connected to the debugging arch frame, and the bottom of the debugging arch frame is connected to the lifting cross bar; the top of the main pushing frame is connected to the nut, and the nut is located at the top of the debugging arch frame; the outside of the main pushing frame is connected to the upper pulling frame, the force-bearing movable frame and the lifting cross bar cross the upper pulling frame, and the top of the upper pulling frame is connected with bolts.

[0007] Furthermore, the pressure roller is rotatably connected to the force-bearing movable frame, sliders A are provided at both ends of the force-bearing movable frame, lower movable holes are provided on both sides of the main pushing frame, and the sliders A are slidably connected to the lower movable holes.

[0008] Furthermore, a guide rod is provided on the top of the force-bearing movable frame, a guide hole is provided inside the lifting cross bar, and the guide rod slides through the guide hole.

[0009] Furthermore, a spring A is mounted on the outside of the guide rod, the bottom end of the spring A contacts the force-bearing movable frame, and the top end of the spring A contacts the lifting cross bar. After the bottom side of the polyolefin waterproof membrane is heated and melted, the force-bearing movable frame moves downward under the thrust of the spring A, so that the pressure roller is pressed against the top side of the polyolefin waterproof membrane. The polyolefin waterproof membrane is in close contact with the building surface under the influence of pressure.

[0010] Furthermore, sliders B are provided at both ends of the lifting crossbar, upper movable holes are provided on both sides of the main pushing frame, the sliders B are slidably connected in the upper movable holes, and the ends of the sliders B are connected to the debugging arch frame.

[0011] Furthermore, a through hole is provided on the top of the debugging arch frame, and a vertical rod is provided on the top of the main pushing frame. The vertical rod slides through the through hole. The lifting crossbar can be adjusted up and down according to the thickness of the polyolefin waterproof membrane, and the distance between the lifting crossbar and the force-bearing movable frame is changed, thereby changing the thrust applied by the spring A on the force-bearing movable frame, increasing or decreasing the pressure on the polyolefin waterproof membrane. Furthermore, a spring B is sleeved on the outside of the vertical rod, the bottom end of the spring B is in contact with the main pushing frame, and the top end of the spring B is in contact with the debugging arch frame.

[0012] Furthermore, a screw is provided on the top of the main pushing frame, which slides through the debugging arch frame, and the nut is threadedly connected to the outside of the screw. The bottom of the nut is in contact with the top side of the debugging arch frame. When the nut is rotated, the nut drives the lifting cross bar to move downward through the debugging arch frame, and the spring B is forced to contract, and the pressure on the polyolefin waterproof membrane increases.

[0013] Furthermore, the bottom of the force-bearing movable frame contacts the inner side of the upper pulling frame, a guide groove is provided on the top of the main pushing frame, the upper pulling frame is slidably connected in the guide groove, a screw hole is provided on the top of the upper pulling frame, the bolt is threadedly connected in the screw hole, and the end of the bolt contacts the top of the screw rod. Before the device is pushed and transferred on the road surface, the bolt is rotated, and the bolt drives the force-bearing movable frame to move upward through the upper pulling frame, so that the pressure roller is away from the ground, avoiding wear on the pressure roller during the pushing and transferring process.

[0014] The present invention provides a device for laying and fixing thermoplastic polyolefin waterproofing membrane for construction engineering, which has the following beneficial effects: When the present invention is in use, the slider A and the lower movable hole are slidably matched, and this design provides precise guidance for the up and down movement of the force-bearing movable frame; the setting of the spring A gives the force-bearing movable frame an elastic reset function; after the bottom side of the polyolefin waterproof membrane is heated and melted, the force-bearing movable frame moves downward steadily under the thrust applied by the spring A, thereby driving the pressure roller to fit tightly against the top side of the polyolefin waterproof membrane; the polyolefin waterproof membrane is in close contact with the building surface under the uniform pressure applied by the pressure roller; this close fitting method can effectively ensure the stability of the laying of the polyolefin waterproof membrane, effectively improve its fixing effect, and ultimately provide reliable waterproof protection for the building surface.

[0015] Furthermore, slider B forms a sliding fit with the upper movable hole, providing precise guidance for the vertical movement of the lifting rod. Given the varying thicknesses of polyolefin waterproofing membranes, this device allows for flexible adjustment of the lifting rod. By adjusting the distance between the lifting rod and the load-bearing movable frame, the thrust applied by spring A on the load-bearing movable frame can be effectively varied, thereby increasing or decreasing the pressure on the polyolefin waterproofing membrane accordingly. This allows for better adaptation to the actual requirements of polyolefin waterproofing membrane installations of varying thicknesses. When the nut is rotated, it drives the adjustment arch, which in turn moves the lifting rod downward. This forces spring B to contract, increasing the pressure on the polyolefin waterproofing membrane. Conversely, when the nut is rotated in the opposite direction, the adjustment arch, driven by the thrust generated by spring B, moves the lifting rod upward, reducing the pressure on the polyolefin waterproofing membrane. This adjustment method is convenient and allows for flexible pressure adjustment.

[0016] In addition, the guide groove plays a key guiding role, which can guide the upper pulling frame to move up and down smoothly; when the device needs to be pushed and transferred on the road, the operator only needs to turn the bolt. During the rotation, the bolt will drive the upper pulling frame to move up synchronously, thereby prompting the force-bearing movable frame to rise accordingly, so that the pressure roller maintains a certain distance from the ground, effectively avoiding wear caused by contact and friction between the pressure roller and the ground during the pushing and transferring process; and before laying the polyolefin waterproof membrane, the operator needs to turn the bolt in the opposite direction. At this time, the bolt will drive the upper pulling frame to move downward to the lowest position. In this state, the force-bearing movable frame can resume the function of free up and down movement, thereby ensuring that during the laying process of the membrane, the pressure roller can always be closely attached to the top side of the polyolefin waterproof membrane, effectively guaranteeing the laying and compacting effect of the polyolefin waterproof membrane.
