Technical Field

[0001] The present invention relates to the field of construction, particularly to the technical field of waterproof coiled materials for construction, and specifically refers to a device for laying and fixing waterproof coiled materials in construction engineering and a method for laying and fixing the same. Background Art

[0002] In construction engineering, waterproof coiled materials are definitely used. In the process of laying waterproof coiled materials, the existing method is manual laying, with low laying efficiency and high labor cost. Especially when laying on a relatively long ground, it is rather troublesome. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the present invention provides a device for laying and fixing waterproof coiled materials in construction engineering and a method for laying and fixing the same, which can improve the laying efficiency and reduce the labor cost of laying.

[0004] The present invention is realized through the following technical solutions. A device for laying and fixing waterproof coiled materials in construction engineering includes a trolley provided with a bracket. On the trolley, there are successively arranged along the moving direction of the trolley a coating device for applying adhesive, a placing device for placing the waterproof coiled material, and a pressing device for pressing the waterproof coiled material and sliding along the moving direction of the trolley.

[0005] When the present invention is in use, place the waterproof coiled material on the placing device, then pull the waterproof coiled material to the pressing device, and use the pressing device to press the waterproof coiled material. Then drive the trolley forward, and at the same time drive the pressing device backward so that the pressing device does not move. After moving a certain distance, stop driving the pressing device backward and make the pressing device move with the trolley. During the movement, press the waterproof coiled material. When the trolley stops moving, drive the pressing device to continue moving forward to press and fix the remaining part of the waterproof coiled material. Through the settings of the coating device, placing device, cutting device, and pressing device, the laying efficiency is improved and the labor cost of laying is reduced.

[0006] Preferably, the coating device includes a material cylinder located on the trolley and filled with adhesive, a feeding pipe communicating with the material cylinder and extending below the trolley body, and a pushing plate fixedly connected to the trolley behind the feeding pipe. A V-shaped groove is opened at the front end of the pushing plate.

[0007] When this preferred solution is in use, the adhesive flows from the material cylinder onto the ground in front of the pushing plate and spreads around. When the pushing plate moves to the position of the adhesive, it pushes the adhesive to move along the moving direction of the trolley, thereby realizing the application of the adhesive.

[0008] Preferably, the bottom surface of the push plate is provided with a plurality of first perforations located on both sides of the V-shaped groove and arranged along the moving direction of the trolley. The first perforations extend along the height direction and are penetrated by suction pipes. The suction pipes are connected to the pump body on the trolley, and the pump body is connected to the feed port of the barrel.

[0009] When the preferred solution is in use and there is too much adhesive, the pump body is opened to absorb the adhesive that flows under the suction tube and return it to the barrel, thereby avoiding waste of adhesive.

[0010] Preferably, the trolley is provided with a long hole for the material delivery pipe to pass through, and the long hole extends perpendicular to the moving direction of the trolley. The material delivery pipe includes a first section, a hose section, and a second section connected in sequence. The first section is connected to the barrel and is provided with a valve. The hose section includes a hose, and the second section passes through the long hole. The trolley is also provided with a first driving device connected to the second section and pushing the second section to move along the long hole.

[0011] When this preferred solution is in use, the first driving device is driven to extend, and the first driving device drives the second section to slide in the long hole, so that the adhesive flows evenly to the bottom surface along the width direction of the waterproof membrane, reducing the diffusion time of the adhesive and improving the laying efficiency.

[0012] Preferably, the placement device includes a rotating roller axially connected to the bracket and for the waterproof membrane to be sleeved, a first tensioning roller and a second tensioning roller located behind the rotating roller and axially connected to the bracket, the second tensioning roller is located above the first tensioning roller, and the waterproof membrane passes around from under the first tensioning roller and out from above the second tensioning roller.

[0013] This preferred solution achieves tensioning of the waterproof coiled material by disposing a first tensioning roller and a second tensioning roller.

[0014] Preferably, the pressing device includes a slider slidingly connected to the bracket along the moving direction of the trolley, a second driving device with two protruding ends extending downward is fixedly connected under the slider, a connecting plate is hinged on the protruding end of the second driving device, and the bottom surface of the connecting plate is hinged with a pressing plate extending along the width direction of the waterproof membrane, the pressing plate is connected to the connecting plate through a torsion spring, and the trolley is provided with a third driving device for driving the slider to slide.

[0015] When this preferred solution is in use, the second driving device is driven to extend, so that the connecting plate drives the pressing plate to press onto the ground, and the pressing plate is tilted backward. Under the elastic force of the torsion spring, the pressing plate is pressed onto the ground, and the waterproof membrane is placed under the pressing plate, thereby achieving the fixation of the waterproof membrane; through the setting of the two second driving devices, the extension length of the two second driving devices is adjusted, thereby facilitating the adjustment of the inclination angle of the connecting plate, thereby further adjusting the inclination angle of the pressing plate, that is, adjusting the compression angle of the torsion spring, thereby achieving the adjustment of the pressing force of the pressing plate, thereby facilitating the laying of waterproofing.

[0016] Preferably, there are two pressing plates. The two pressing plates are arranged along the moving direction of the trolley, and the height of the pressing plate at the rear is greater than that of the pressing plate at the front. The torsion spring is located behind the pressing plate. With the arrangement of the two pressing plates in this preferred solution, it is convenient to fully press the waterproof coiled material.

[0017] Preferably, one end of the connecting plate close to the trolley is pivotally connected with a guiding roller, and the waterproof coiled material bypasses the guiding roller and extends to the lower side of the pressing plate. With the arrangement of the guiding roller in this preferred solution, when the waterproof coiled material and the connecting plate move relatively, it can avoid the situation that the waterproof coiled material contacts the end face of the connecting plate and causes damage to the waterproof coiled material.

[0018] Preferably, the cutting device includes a knife handle pivotally connected to the trolley and extending to the front of the position where the pressing device presses the waterproof coiled material. A blade extending upward is fixedly connected to the end of the knife handle away from the trolley. Both the knife handle and the blade extend along the width direction of the waterproof coiled material. A fourth driving device for driving the knife handle to rotate is also fixedly connected to the trolley.

[0019] When using this preferred solution, drive the fourth driving device to drive the knife handle to rotate upward, and the knife handle drives the blade to rotate upward to cut the waterproof coiled material.

[0020] The laying and fixing method of the building engineering waterproof coiled material laying and fixing device includes the following steps:

[0021] a. Drive the trolley to move, and open the valve. Drive the first driving device to expand and contract along the width direction of the waterproof coiled material. The adhesive is sprayed onto the ground and is evenly smeared under the drive of the pushing plate. At this time, the pressing device moves synchronously with the trolley. After moving a certain distance, stop moving.

[0022] b. Sleeve the waterproof coiled material on the rotating roller, bypass the waterproof coiled material under the first tensioning roller, wind it out from above the second tensioning roller, and then bypass the guiding roller and extend to the lower side of the pressing roller.

[0023] c. Drive the two second driving devices to extend, and make the length of the second driving device at the front extend greater than that of the other second driving device, so that the connecting plate inclines forward and downward. At the same time, under the elastic force of the torsion spring, the pressing plate presses the waterproof coiled material onto the ground, and the pressing plate inclines backward and downward.

[0024] d. Drive the trolley to move forward, and open the valve. Drive the first driving device to expand and contract along the width direction of the waterproof coiled material. The adhesive is sprayed onto the ground and is evenly smeared under the drive of the pushing plate. At the same time, drive the third driving device to extend backward, so that the pressing plate presses the coiled material without displacement. After the trolley moves a certain distance, stop the third driving device from extending, so that the pressing plate moves synchronously with the trolley, thereby realizing the pressing of the coiled material.

[0025] e. When the laying is about to be completed, close the valve. After the trolley moves a certain distance and then stops moving, drive the third driving device to contract, so that the pressing plate continues to move forward for a certain distance. Finally, drive the fourth driving device to drive the knife handle to rotate upward, and the rotation of the knife handle drives the blade to cut the waterproof coiled material.

[0026] The beneficial effects of the present invention are as follows: Through the settings of the coating device, placement device, cutting device, and pressing device, the laying efficiency is improved, and the labor cost of laying is reduced; through the setting of the straw moving along the width direction of the waterproof coiled material, it is convenient for the uniform coating of the adhesive; through the settings of the first tensioning roller and the second tensioning roller, the tensioning of the waterproof coiled material is achieved; through the settings of the two second driving devices, the lengths of the two second driving devices extending are adjusted, so as to facilitate the adjustment of the inclination angle of the connecting plate, and further adjust the inclination angle of the pressing plate, that is, adjust the compression angle of the torsion spring, so as to achieve the adjustment of the pressing force of the pressing plate, and thus facilitate the laying of the waterproof.
