Description

Technical Field

[0001] This invention relates to the field of waterstop installation technology, and more specifically, to a standardized template structure and its construction method for assisting in the installation of flexible waterstops. Background Technology

[0002] Flexible waterstops are materials used for waterproofing and sealing in building structures. They are typically made of rubber, polyurethane, polyethylene, or other elastic materials. The main function of flexible waterstops is to prevent moisture, humidity, or other liquids from seeping into the building's interior through gaps or joints, thus preventing water damage and protecting the structure. They are commonly used within expansion joints in building structures. Due to temperature changes, foundation settlement, and other factors, building structures expand and contract to a certain extent; flexible waterstops are installed at these expansion joints to prevent moisture penetration.

[0003] The current installation of flexible waterstops in expansion joints is mostly done manually. This involves inserting the two side walls of the flexible waterstop into a pre-cast groove in the expansion joint, and then using adhesive to fill and fix it in place. However, this process requires workers to squat for extended periods, resulting in high labor intensity and low efficiency. This can easily lead to extended project timelines and increased labor costs. Summary of the Invention

[0004] The purpose of this invention is to provide a standardized template structure and its construction method for assisting in the installation of flexible waterstops, which can facilitate the installation of flexible waterstops and effectively improve construction efficiency and reduce labor costs.

The lower feeding roller has a flanged protrusion integrally provided on the end near the flanged plate. At the same time, multiple feeding protrusions are fixedly provided on the peripheral wall of each feeding roller.

[0008] Furthermore, the material guiding mechanism includes a positioning plate and a transition plate. The positioning plate corresponds one-to-one with the flange plate and is used to be inserted into the prefabricated groove of the waterstop installed on the expansion joint. The transition plate is set between the positioning plate and the flange plate, and its two ends are smoothly connected to the positioning plate and the flange plate.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention. Example

[0021] The following description, in conjunction with specific embodiments, provides further details. Figures 1-6As shown, this invention is a standardized template structure for assisting in the installation of flexible waterstops, including a frame 2. The frame 2 includes L-shaped plates 21, guide plates 22, and flanged plates 23. Two L-shaped plates 21 are installed opposite each other and are used to engage with the gaps in the expansion joint 1. Multiple rollers 211 are fixedly installed on the L-shaped plates 21, abutting against the top wall of the expansion joint 1 to facilitate movement of the frame 2. Multiple ball bearings 212 are embedded on the opposing surfaces of the two L-shaped plates 21 to facilitate movement of the two L-shaped plates 21 along the expansion joint 1. The guide plates 22 correspond one-to-one with the L-shaped plates 21, and are respectively fixedly welded to the opposing surfaces of the two L-shaped plates 21. The two guide plates 22 are slidably interlocked and inclined. Extending gradually from above the expansion joint 1 into the prefabricated groove 11 where the waterstop is installed, the flange plate 23 has an L-shaped cross section and is fixedly installed on the opposite surfaces of two L-shaped plates 21. The flange plate 23 is installed at intervals above the guide plate 22, and the flange plate 23 is set along the length of the guide plate 22. A closing frame 231 is installed on the side of the flange plate 23 and the guide plate 22 that extends out of the expansion joint 1. The closing frame 231 is fixedly connected to the two L-shaped plates 21 and is used to close the gap between the flange plate 23 and the guide plate 22 so that the waterstop can be turned up smoothly. Each flange plate 23 is also rotatably installed with multiple guide rollers 8 along the length direction. The guide rollers 8 are located above the guide plate 22 and have gaps for the waterstop to pass through, so as to limit and guide the waterstop. Reference Figure 2 , Figure 3 In order to adjust the gap between the two L-shaped plates 21 to accommodate expansion joints 1 of different widths, a double-headed cylinder 24 is installed between the two L-shaped plates 21. The piston rods at both ends of the cylinder are fixedly connected to the two L-shaped plates 21 respectively, and an operating handle 241 is fixedly connected to the cylinder body. The feeding roller 25 is rotatably installed on the frame 2 through the fixing frame 251. The fixing frame 251 is fixedly welded to the closed frame 231. After the waterstop roll is installed on the feeding roller 25, the waterstop roll can be released, which facilitates the operation of the staff and improves the construction efficiency. Reference Figure 3 , Figure 5The straightening mechanism 3 is installed in front of the frame 2 and is used to straighten and align the waterstop. The straightening mechanism 3 includes a support frame 31, a rodless cylinder 32, a reciprocating motor 33, a return frame 34, and a feed plate 35. The support frame 31 is fixedly welded to one of the support plates 43. The cylinder body of the rodless cylinder 32 is vertically fixedly welded to the support frame 31. The reciprocating motor 33 is fixedly installed on the output shaft of the rodless cylinder 32. The return frame 34 is fixedly connected to the output shaft of the reciprocating motor 33. The feed plate 35 is fixedly welded to the support frame 31. On the inner walls above and below the frame of the U-shaped frame 34, two feed plates 35 are arranged in an inward arch. The waterstop passes between the feed plates 35 above and below the frame of the U-shaped frame 34. The two feed plates 35 can guide the waterstop. In the continuous forward and reverse cycle of the reciprocating motor 33 and the up and down movement of the U-shaped frame 34 driven by the rodless cylinder 32, the waterstop can be straightened and aligned efficiently to prevent the waterstop from knotting or scattering and affecting normal feeding and flanging. Reference Figure 2 , Figure 4 The feeding mechanism 4 is installed between the straightening mechanism 3 and the frame 2 and is used to transport the waterstop strip straightened by the straightening mechanism 3 into the guide plate 22. The feeding mechanism 4 is installed on two sets of closed frames 231 located on both sides of the frame 2. Each set of feeding mechanism 4 includes two upper and lower feeding rollers 41 and a feeding motor 42. A support plate 43 is fixedly welded to the closed frame 231. The feeding rollers 41 are rotatably mounted on the support plate 43. The feeding motor 42 corresponds one-to-one with the feeding rollers 41. The feeding motor 42 is fixedly connected to the closed frame 231. The output shafts of the feeding rollers 41 and the feeding motor 42 are fixed. Connected together, the upper feed roller 41 has a flange groove 411 annularly opened near the flange plate 23, and the lower feed roller 41 has a flange protrusion ring 412 coaxially and integrally provided at the end near the flange plate 23. At the same time, multiple feed protrusions 413 are fixedly welded to the surface of each feed roller 41. The waterstop can be smoothly and quickly flanged by the guide of the flange groove 411 and the flange protrusion ring 412, so as to enter the guide plate 22. The feed protrusions 413 can increase the pressure on the waterstop, making it easier to pull the waterstop into the guide plate 22 and preventing the waterstop from slipping. Reference Figure 2 , Figure 3 The material guiding mechanism 5 is installed at the rear of the frame 2 and is used to guide the waterstop tape sent out from the tail of the frame 2 into the prefabricated groove 11 of the waterstop tape installed on the expansion joint 1. The material guiding mechanism 5 includes a positioning plate 51 and a transition plate 52. The positioning plate 51 corresponds one-to-one with the flange plate 23 and is used to be inserted into the prefabricated groove 11 of the waterstop tape installed on the expansion joint 1. The transition plate 52 is installed between the positioning plate 51 and the flange plate 23, and its two ends are smoothly connected to the positioning plate 51 and the flange plate 23. Reference Figure 1 , Figure 2The positioning mechanism 6 is used to fix and reinforce the waterstop strip in the precast groove 11 of the expansion joint 1. Two sets of positioning mechanisms 6 are installed and correspondingly located on the two positioning plates 51. Each set of positioning mechanisms 6 includes an electric nail gun 61, an infrared position sensor 62, and a controller 63. The electric nail gun 61 is fixedly installed on the positioning plate 51, and the nozzle of the electric nail gun 61 is tilted downward and facing into the precast groove 11 where the waterstop strip is installed. The infrared position sensor 62 is fixedly connected to the electric nail gun 61. The infrared position sensor 62 is used to send an electrical signal to the controller 63 after detecting the passage of the waterstop strip. After receiving the electrical signal sent by the infrared position sensor 62, the controller 63 controls the electric nail gun 61 to fire. The waterstop is fixed with steel nails; the positioning mechanism 6 also includes a glue tank 64, a pump body 65, and a glue hose 66. The glue tank 64 is fixedly installed on the L-shaped plate 21, and the pump body 65 is fixedly installed on the glue tank 64. The inlet of the pump body 65 is connected to the glue tank, and the outlet of the pump body 65 is connected to one end of the glue hose 66. The other end of the glue hose 66 is connected to the positioning plate 51. The positioning plate 51 is hollow. The side of the positioning plate 51 facing the groove wall of the precast groove 11 where the waterstop is installed has a glue spraying nozzle 511. When the pump body 65 is started, the sealant in the glue tank 64 can enter the positioning plate 51 along the glue hose 66 and be sprayed out through the glue spraying nozzle 511 of the positioning plate 51 to the two end walls of the waterstop, so as to achieve rapid fixing of the waterstop.

[0022] Reference Figure 2 , Figure 3 At the rear of the frame 2, below the positioning plate 51 and transition plate 52, a receiving plate 7 is installed. The receiving plate 7 can support and guide the waterstop. The cross-section of the receiving plate 7 is 'L' shaped and is fixedly welded to the L-shaped plate 21. The top wall of the receiving plate 7 is arched. At the same time, the arched part of the receiving plate 7 near the L-shaped plate 21 is smoothly connected to the top wall of the guide plate 22. The arched part of the top wall of the receiving plate 7 can facilitate the straightening and turning of the waterstop, and at the same time prevent the glue from leaking along the middle of the expansion joint 1. A drying fan 71 is fixedly installed at the end of the receiving plates 7 away from the L-shaped plate 21 on both sides. The air outlet of the drying fan 71 is inclined towards the groove wall of the prefabricated groove 11 of the waterstop, so as to facilitate the rapid drying of the waterstop with sealant.

[0023] In addition, a construction method for a standardized formwork structure used to assist in the installation of flexible waterstops also includes: S1: First, pull the operating handle 241 to move the entire frame 2 to the building expansion joint 1, align the two L-shaped plates 21 with the expansion joint 1 and move them in, so that the rollers 211 on the two L-shaped plates 21 support the top wall of the expansion joint 1; S2: During this period, the dual-head cylinder 24 is activated, which opens the two L-shaped plates 21 to support the side wall of the expansion joint 1; S3: Then, the waterstop roll is installed on the feeding roller 25, and the end of the waterstop is pulled along the inside of the U-shaped frame 34, the gap between the two sets of feeding rollers 41, and the guide plate 22 to introduce it; S4: Start the feeding motor 42 to drive the waterstop into the prefabricated groove 11 of the waterstop installed on the expansion joint 1. During this process, start the rodless cylinder 32 and the reciprocating motor 33 to drive the return frame 34 to move up and down and swing back and forth to correct the waterstop. S5: Start the pump body 65 to spray adhesive into the precast groove 11 of the waterstop. After the waterstop enters the precast groove 11, the adhesive will wrap around the waterstop to fix it. When the infrared position sensor 62 detects the waterstop passing through, the controller 63 will control the electric nail gun 61 to shoot out steel nails to fix the waterstop again. S6: Start the drying fan 71 to quickly dry the adhesive, so that the waterstop is quickly fixed; S7: Pull the operating handle 241 along the length of the expansion joint 1 until the installation of the waterstop of the entire expansion joint 1 is completed.
