Description

Technical Field

[0001] This application relates to the field of waterproof membrane installation technology, and in particular to a waterproof membrane installation device. Background Technology

[0002] In the field of building waterproofing engineering, waterproof membranes are widely used and play a crucial role in the waterproof protection of buildings. Properly laid waterproof membranes can effectively prevent water penetration, avoid damage to the building's internal structure due to dampness, reduce maintenance costs, and improve the building's durability and safety.

[0003] The waterproof membrane to be laid includes a waterproof layer. Below the waterproof layer, from its width along one side towards the center, are arranged a first hook and loop fastener, a sealing strip, a second hook and loop fastener, an expansion sealant, and a waterproof adhesive layer. The first hook and loop fasteners, sealing strip, second hook and loop fasteners, expansion sealant, and waterproof adhesive layer are symmetrically arranged on both sides below the waterproof layer. One side of the first and second hook and loop fasteners is fixed to the waterproof layer, and the other side is covered with waterproof adhesive tape.

[0004] When applying the new waterproof membrane to the joints of adjacent existing waterproof membranes on the floor slab, and quickly sealing the joints, first clean the joints of the existing membranes on the upper surface of the floor slab. Then, attach the side of the first and second Velcro straps with waterproof tape to the existing membrane, ensuring the waterproof adhesive layer adheres to the joint between the two membranes. This will achieve a waterproof seal at the joints of the adjacent membranes.

[0005] However, during the installation process, the construction workers need to press and apply the waterproof adhesive layer and waterproof tape of the waterproof membrane section by section by hand. This is not only time-consuming and labor-intensive, but also makes it easy for the newly installed waterproof membrane to be unevenly laid in some areas, creating gaps and affecting the waterproof sealing performance of the newly installed waterproof membrane at the joints with the adjacent original membrane. Utility Model Content

[0006] In order to improve the waterproof sealing performance of the newly laid waterproof membrane at the joints of adjacent original membranes and to improve the laying efficiency of construction workers, this application provides a waterproof membrane laying device.

[0007] This application provides a waterproof membrane laying device, which adopts the following technical solution:

[0008] A waterproof roll material laying device includes a pressing laying frame, a support frame, and a gas spring. The support frame and the pressing laying frame are hinged together at a hinge point. One end of the gas spring is hinged to the pressing laying frame, and the other end is hinged to the support frame. The support frame forms a triangular support structure with the pressing laying frame through the elastic action of the gas spring, and the support frame can be stored close to the side of the pressing laying frame. A pressure roller is provided at the bottom of the pressing laying frame.

[0009] By adopting the above technical solution, new waterproof membrane is applied to the joints of adjacent existing waterproof membranes on the floor slab. When quickly sealing these joints, first clean the joints of the existing membranes on the upper surface of the floor slab. Place the new waterproof membrane as required, and move the support frame away from the lowering frame. Under the action of the gas spring, a stable triangular support structure is formed between the lowering frame, the support frame, and the gas spring. Then, push the device to allow the pressure roller at the bottom of the lowering frame to apply the waterproof membrane. The gas spring allows the support frame to be fixed closer to or further away from the lowering frame, enabling storage or... A stable triangular support structure is formed to facilitate the installation of the waterproof membrane laying device. When the construction workers move the waterproof membrane laying device to the construction site, they can quickly open and support the device to carry out the laying work. By pushing the laying frame and support frame forward and applying a certain pressure during the movement, the pressure roller can be driven to apply pressure to the new waterproof membrane. This allows the pressure roller to quickly adhere the new waterproof membrane to the joint of the adjacent original membrane below. Compared with manual pressing and laying section by section, this method saves time and labor, and ensures that the waterproof membrane adheres better to the original membrane, improving the waterproof sealing of the new waterproof membrane at the joint of the adjacent original membrane, reducing gaps, and ensuring the quality of the laying.

[0010] Optionally, a telescopic rod is fixed between the pressure roller and the lower pressing and laying frame, and an anti-overpressure spring is sleeved on the outside of the telescopic rod.

[0011] By adopting the above technical solution, when the pressure roller is subjected to greater pressure, the telescopic rod will extend and retract accordingly, and the overpressure spring will be compressed or stretched to buffer and regulate the pressure, avoiding excessive pressure at any moment; preventing damage to the outer surface of the waterproof membrane due to excessive pressure when laying and pressing the waterproof membrane, and ensuring the integrity of the waterproof membrane and the quality of laying.

[0012] Optionally, positioning wheels are fixed at both ends of the pressure roller, and the distance between the two positioning wheels matches the width of the waterproof membrane.

[0013] By adopting the above technical solution, during the waterproof membrane laying process, since the distance between the two positioning wheels matches the width of the waterproof membrane, when the waterproof membrane laying device moves, the positioning wheels will move along the edge of the waterproof membrane, playing a guiding role. This ensures that the laying device always moves along the length of the waterproof membrane, so that the laying device will not deviate from the originally planned laying direction, guaranteeing the straightness and accuracy of the waterproof membrane laying, avoiding problems such as uneven membrane splicing and uneven gaps caused by deviations in the laying direction, and improving the laying quality of the waterproof membrane.

[0014] Optionally, multiple pressure rollers are provided, and the multiple pressure rollers are arranged in parallel, with the bottom of the multiple pressure rollers on the same plane.

[0015] By adopting the above technical solution, when laying waterproof membrane, multiple pressure rollers on the same plane work together. These pressure rollers apply pressure to the waterproof membrane as the laying frame moves, so that the entire surface of the waterproof membrane is subjected to uniform pressure, ensuring that all parts of the newly laid waterproof membrane can fully adhere to the original membrane, reducing the occurrence of local non-adhesion or loose adhesion.

[0016] Optionally, the outer side of the pressure roller is fitted with a plurality of counterweight roller sleeves that rotate axially.

[0017] By adopting the above technical solution, the arrangement of multiple counterweight roller sleeves along the axial direction of the pressure roller corresponds one-to-one with the arrangement of the first hook and loop fasteners, the second hook and loop fasteners, and the waterproof adhesive layer under the waterproof membrane. Therefore, during the rotation of the counterweight roller sleeves, they can apply precise and uniform pressure to the corresponding positions of the newly laid waterproof first hook and loop fasteners, the second hook and loop fasteners, and the waterproof adhesive layer, ensuring that the waterproof tape and waterproof adhesive layer on the back of the first hook and loop fasteners and the second hook and loop fasteners have good adhesion to the surface of the original membrane, thereby improving the waterproof sealing performance of the newly laid waterproof membrane at the joint of the adjacent original membrane.

[0018] Optionally, a support roller is rotatably connected to the bottom of the support frame, and the bottom of the support roller is on the same plane as the bottom of the counterweight roller sleeve.

[0019] By adopting the above technical solution, the support roller rotates at the bottom of the support frame and rolls as the waterproof membrane laying device moves. Since the bottom of the support roller and the bottom of the counterweight roller sleeve are on the same plane, the entire device can move smoothly on the ground, ensuring flat laying.

[0020] Optionally, both the outer side of the counterweight roller sleeve and the outer side of the support roller are wrapped with a wear-resistant rubber layer.

[0021] By adopting the above technical solution, the wear-resistant rubber layer wrapped on the outside of the counterweight roller sleeve and the outside of the support roller will directly contact the outer surface of the waterproof membrane, reducing frictional loss with the outer surface of the waterproof membrane, protecting the newly laid outer surface of the waterproof membrane at the joint of the adjacent original membrane from damage, and ensuring the surface quality of the waterproof membrane.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The gas spring allows the support frame to be fixed near or away from the lower pressing and laying frame, achieving storage or forming a stable triangular support structure to facilitate the installation of the waterproof membrane. When construction workers move the waterproof membrane laying device to the site, they can quickly open and support it to begin laying. Then, by pushing the lower pressing and laying frame forward and applying downward pressure during the movement, the pressure roller applies pressure to the new waterproof membrane, quickly adhering it to the joint of the adjacent original membrane. Compared to manual pressing and laying section by section, this method saves time and effort, ensures better adhesion of the waterproof membrane to the original membrane, improves the waterproof sealing of the new waterproof membrane at the joint of the adjacent original membrane, reduces gaps, and guarantees laying quality.

[0024] 2. When the pressure roller is subjected to greater pressure, the telescopic rod will extend and retract accordingly, and the overpressure spring will be compressed or stretched to buffer and regulate the pressure, avoiding excessive pressure in an instant; preventing damage to the outer surface of the waterproof membrane due to excessive pressure when laying and pressing the waterproof membrane, and ensuring the integrity of the waterproof membrane and the quality of laying.

[0025] 3. The arrangement of multiple counterweight roller sleeves along the axial direction of the pressure roller corresponds one-to-one with the arrangement of the first hook and loop fasteners, the second hook and loop fasteners, and the waterproof adhesive layer under the waterproof membrane; therefore, during the rotation of the counterweight roller sleeves, they can apply precise and uniform pressure to the corresponding positions of the newly laid waterproof first hook and loop fasteners, the second hook and loop fasteners, and the waterproof adhesive layer, ensuring that the waterproof tape and waterproof adhesive layer on the back of the first hook and loop fasteners and the second hook and loop fasteners have good adhesion to the surface of the original membrane.

[0030] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0031] This application discloses a waterproof membrane laying device. (Refer to...) Figure 1 and Figure 2 The waterproof membrane 1 to be laid now includes a waterproof layer 11. Below the waterproof layer 11, from its width along its edge towards the center, are arranged a first hook and loop fastener 12, a sealing strip 13, a second hook and loop fastener 14, an expansion sealant 15, and a waterproof adhesive layer 16. The first hook and loop fastener 12, sealing strip 13, second hook and loop fastener 14, expansion sealant 15, and waterproof adhesive layer 16 are symmetrically arranged on both sides below the waterproof layer 11. One side of the first hook and loop fastener 12 and the second hook and loop fastener 14 are fixed to the waterproof layer 11, and the other side is covered with waterproof adhesive tape 17.

[0032] The waterproof membrane laying device in this application is used to lay the new waterproof membrane 1 at the joints of adjacent original membrane 3 laid on the upper surface of the floor slab 2, and to quickly seal the joints of the adjacent original membrane 3. During the laying process, firstly, the joints of the original membrane 3 laid on the upper surface of the floor slab 2 are wiped clean. Then, the side of the first Velcro 12 and the second Velcro 14 with waterproof tape 17 is bonded to the laid original membrane 3. At the same time, the waterproof adhesive layer 16 is adhered to the joint of the two original membranes 3, thus achieving a waterproof seal at the joint of adjacent original membranes 3.

[0033] Reference Figure 1 and Figure 2 The waterproof membrane 1 laying device includes a pressing laying frame 4, a support frame 5, and a gas spring 6. The support frame 5 and the pressing laying frame 4 are hinged together at a hinge point. One end of the gas spring 6 is hinged to the pressing laying frame 4, and the other end is hinged to the support frame 5. When the support frame 5 moves, the elasticity of the gas spring 6 can be used to retract the support frame 5 to the side close to the pressing laying frame 4, saving storage space. At the same time, a stable triangular support structure can be formed between the support frame 5 and the pressing laying frame 4, which facilitates the support of the laying device and thus enables the laying construction.

[0034] The bottom of the pressing and laying frame 4 is equipped with multiple parallel pressure rollers 7, with the bottom of the multiple pressure rollers 7 on the same plane. The pressure rollers 7 can apply pressure to the waterproof membrane 1, making it better adhere to the original membrane 3. When laying the waterproof membrane 1, the multiple pressure rollers 7 on the same plane work together. The pressure rollers 7 move with the pressing and laying frame 4, and apply pressure to the waterproof membrane 1 at the same time, so that the entire surface of the waterproof membrane 1 is subjected to uniform pressure, ensuring that all parts of the newly laid waterproof membrane 1 can fully adhere to the original membrane 3, reducing the occurrence of local non-adhesion or loose adhesion.

[0035] When laying a new waterproof membrane 1 at the joint of the adjacent original membrane 3 laid on the floor slab 2, first wipe the joint of the original membrane 3 laid on the upper surface of the floor slab 2 clean, place the new waterproof membrane 1 as required, move the support frame 5 away from the side of the pressing frame 4, and under the action of the gas spring 6, the pressing frame 4, the support frame 5 and the gas spring 6 form a stable triangular support structure. Then push the device so that the pressure roller 7 at the bottom of the pressing frame 4 can lay the waterproof membrane 1.

[0036] Specifically, refer to Figure 1 and Figure 2 A telescopic rod 71 is fixed between the pressure roller 7 and the lower pressing and laying frame 4. An overpressure spring 72 is sleeved on the outside of the telescopic rod 71. One end of the overpressure spring 72 abuts against the lower pressing and laying frame 4, and the other end abuts against the pressure roller 7, and it is always in a compressed state. The telescopic rod 71 consists of inner and outer sleeves. The inner sleeve can slide inside the outer sleeve to realize the extension and retraction adjustment of its length. When the pressure roller 7 is subjected to greater pressure, the telescopic rod 71 will extend and retract accordingly, and the overpressure spring 72 will be further compressed to buffer and regulate the pressure, avoid excessive pressure at any moment, and prevent damage to the outer surface of the waterproof membrane 1 due to excessive pressure when laying and pressing it, so as to ensure the integrity of the waterproof membrane 1 and the laying quality.

[0037] Reference Figure 1 and Figure 2Positioning wheels 73 are fixed at both ends of the pressure roller 7, and the distance between the two positioning wheels 73 matches the width of the waterproof membrane 1. The positioning wheels 73 can be rubber or plastic wheels, and are fixed to both ends of the pressure roller 7 by bolts or welding. During the movement of the laying device, the positioning wheels 73 ensure that the laying device moves along the length of the waterproof membrane 1, preventing deviation from the original planned laying direction and ensuring the straightness and accuracy of the waterproof membrane 1 laying. Multiple counterweight roller sleeves 74 are rotatably fitted around the outer side of the pressure roller 7 along its axial direction, and the arrangement of the multiple counterweight roller sleeves 74 along the axial direction of the pressure roller 7 corresponds one-to-one with the arrangement positions of the first Velcro 12, the second Velcro 14, and the waterproof adhesive layer 16 below the waterproof membrane 1. The counterweight roller sleeves 74 are made of metal to increase their weight. The counterweight roller sleeves 74 are connected to the pressure roller 7 by bearings or bushings. During the installation process, the counterweight roller sleeve 74 can apply precise and uniform pressure to the corresponding positions of the first hook and loop fastener 12, the second hook and loop fastener 14 and the waterproof adhesive layer 16, ensuring the adhesion of the waterproof tape 17 and the waterproof adhesive layer 16 on the back of the first hook and loop fastener 12 and the second hook and loop fastener 14 to the surface of the original roll material 3, thereby improving the waterproof sealing performance of the newly installed waterproof roll material 1 at the joint of the adjacent original roll material 3.

[0038] Reference Figure 1 and Figure 3 A support roller 51 is rotatably connected to the bottom of the support frame 5, and the bottom of the support roller 51 is on the same plane as the bottom of the counterweight roller sleeve 74. When the laying device moves, the support roller 51 provides support, making the laying device move more smoothly. Both the outer side of the counterweight roller sleeve 74 and the outer side of the support roller 51 are wrapped with a wear-resistant rubber layer. The wear-resistant rubber layer uses natural rubber or synthetic rubber, such as styrene-butadiene rubber, which has good wear resistance and elasticity, reducing frictional wear with the outer surface of the waterproof membrane 1 and protecting the newly laid outer surface of the waterproof membrane 1 at the joints of adjacent original membranes 3 from damage.

[0039] The implementation principle of the waterproof membrane laying device in this application embodiment is as follows: When laying a new waterproof membrane 1 at the joint of the adjacent original membrane 3 laid on the floor slab 2, and performing a quick sealing treatment at the joint of the adjacent original membrane 3, first wipe the area around the joint of the original membrane 3 laid on the upper surface of the floor slab 2 clean, place the new waterproof membrane 1 as required, move the support frame 5 away from the side of the pressing laying frame 4, and under the action of the gas spring 6, the pressing laying frame 4, the support frame 5 and the gas spring 6 form a stable triangular support structure. Then push the device so that the counterweight roller sleeve 74 at the bottom of the pressing laying frame 4 can apply precise and uniform pressure to the corresponding positions of the first hook and loop fastener 12, the second hook and loop fastener 14 and the waterproof adhesive layer 16, so as to ensure the adhesion of the waterproof tape 17 and the waterproof adhesive layer 16 on the back of the first hook and loop fastener 12 and the second hook and loop fastener 14 to the surface of the original membrane 3, thereby realizing the laying operation of the waterproof membrane 1. The gas spring 6 can fix the support frame 5 to a position close to or far from the lower pressing and laying frame 4, realizing storage or forming a stable triangular support structure to facilitate the support of the laying device for construction. Thus, when the construction personnel move the waterproof membrane 1 laying device to the construction site, they can quickly open and support the waterproof membrane 1 laying device to carry out the laying construction. By pushing the lower pressing and laying frame 4 and the support frame 5 forward and applying a certain pressure downward during the movement, the pressure roller 7 can be driven to apply pressure to the new waterproof membrane 1, so that the pressure roller 7 can quickly stick the new waterproof membrane 1 to the splice of the adjacent original membrane 3 below. Compared with manual pressing and laying section by section, it saves time and labor, and can ensure that the waterproof membrane 1 better fits the original membrane 3, improve the waterproof sealing of the new waterproof membrane 1 to the splice of the adjacent original membrane 3, reduce the generation of gaps, and ensure the laying quality.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
