Description

Technical Field

[0001] The utility model relates to the technical field of SBS coiled material laying, in particular to a reusable SBS coiled material seam alignment fixture. Background Art

[0002] In construction projects, SBS membranes are an important waterproof material and are widely used in waterproofing projects such as roofs, basements, and bathrooms. In order to ensure the waterproof effect, the alignment and clamping and pressing of the joints between SBS membranes are crucial steps.

[0003] Traditional seam alignment methods usually require operators to manually press the seams, which is not only labor-intensive but also difficult to ensure uniform pressing of the seams, thus affecting the waterproofing effect. In addition, most of the tools used by construction workers in waterproofing construction are mini handheld rollers, which are light and easy to carry, but have poor practicality and low efficiency.

[0004] After searching, the Chinese patent with the announcement number CN217353269U discloses a tool for processing the overlap of the seams of waterproof membranes. By adopting a rubber scraper, a pressure roller and a pressure head structure, the sharp-angle structure of the head of the rubber scraper can be used to squeeze the polyethylene film layer and the waterproof membrane, squeeze out the bubbles or impurities between the two, and the pressure head can be used to follow the pre-tightening to prevent the formation of bubbles between the polyethylene film layer and the waterproof membrane. The pre-tightened panel is pressed for the second time under the action of the pressure roller, so that the waterproof membrane is flattened.

[0005] However, in actual use, this structure requires the operator to continuously apply force with his hands to ensure the pressing state during the pressing process using the pressure roller, which is time-consuming and labor-intensive, and may cause discomfort to the user's hands in the long run. In view of this, the present invention provides a reusable SBS coil seam alignment clamp. Utility Model Content

[0006] The utility model provides a reusable SBS coil seam alignment fixture to solve the technical problems existing in the prior art.

[0007] In order to achieve the above purpose, the present invention provides the following technical solution: a reusable SBS coil seam alignment fixture, comprising two support rods, the top ends of the two support rods are jointly mounted with a top plate, and the bottom of the top plate is provided with a self-locking pressing structure.

[0008] In order to facilitate the clamping and pressing operation of the SBS coil seam alignment part and reduce the burden of the operator to press hard, preferably, the self-locking pressing structure includes a connecting rod, which is at the bottom of the top plate and between the two support rods, and sleeves are fixedly provided at both ends of the connecting rod, a feed screw is provided on the surface of the top plate, and an adjusting disk is provided at the top end of the feed screw, two support plates are fixedly provided at the bottom of the connecting rod, and a rotating rod is provided between the two support plates, and the external fixed sleeve of the rotating rod is provided with a clamping roller, and the outer surface of the clamping roller is covered with a rubber sleeve, the sleeves at both ends of the connecting rod are respectively installed on the outside of the corresponding support rod, and the sleeve is slidably connected to the support rod, the bottom end of the feed screw extends to the bottom of the top plate, and is rotatably connected to the connecting rod through a bearing, and the feed screw is threadedly connected to the top plate.

[0009] In order to ensure that the rubber sleeve on the clamping roller fits tightly to the position where the seam is aligned, preferably, a rectangular groove is opened on the inner wall of the two support plates, a rectangular block is slidingly set inside the rectangular groove, and a spring is set at the top of the rectangular block inside the rectangular groove. The two ends of the spring are respectively connected to the rectangular block and the inner wall of the rectangular groove, and the rotating rod is rotatably connected between the two rectangular blocks.

[0010] In order to facilitate the disassembly, assembly and replacement of the rubber sleeve and achieve the purpose of reuse, preferably, the outer surface of the clamping roller and the inner wall of the rubber sleeve are fixedly attached with Velcro, and the rubber sleeve is detachably connected to the clamping roller through the Velcro.

[0011] In order to provide good smoothness when pushing the clamp, preferably, the bottom ends of the two support rods are fixedly mounted with mounting seats, and movable balls are rollingly mounted inside the mounting seats.

[0012] The utility model has the following advantages:

[0013] 1. By setting up a self-locking pressing structure, the rotation of the feed screw drives the connecting rod to drive the rubber sleeve on the clamping roller to press the SBS coil seam alignment part. Due to the thread restriction of the feed screw and the top plate, the clamping roller cannot move upward during the clamping and pressing process of the SBS coil seam alignment part. Therefore, the clamping and pressing of the SBS coil seam alignment part can be completed by simply pushing the clamp, without the need for additional pressing force, which reduces the operating burden.

[0014] 2. The rotating rod at the clamping roller drives the rectangular block to extend upward inside the rectangular groove and squeeze the spring. After being squeezed, the spring resets, which enables the rubber sleeve on the clamping roller to fit tightly against the SBS coil seam alignment part, improving the clamping and pressing effect. The rotating rod rotates between the two rectangular blocks, which enables the clamping roller to drive the rubber sleeve to rotate, facilitating rolling and pressing of the SBS coil seam alignment part.

[0015] 3. The rubber sleeve can be disassembled and assembled between the Velcro and the clamping roller, which is convenient for replacement and cleaning of the rubber sleeve and achieves the purpose of reuse. In addition, the clamp can provide smoothness when pushing through the movable balls rolling at the mounting base at the bottom of the two support rods. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0024] As attached Figure 1-4 The shown embodiment is a reusable SBS coil seam alignment fixture, comprising two support rods 1, the top ends of the two support rods 1 are jointly installed with a top plate 2, the bottom of the top plate 2 is provided with a self-locking pressing structure, the self-locking pressing structure comprises a connecting rod 3, the connecting rod 3 is at the bottom of the top plate 2, and is located between the two support rods 1, both ends of the connecting rod 3 are fixedly provided with a sleeve 4, the surface of the top plate 2 is provided with a feed screw 5, the top end of the feed screw 5 is provided with an adjusting disk 6, two support plates 7 are fixedly provided at the bottom of the connecting rod 3, a rotating rod 8 is provided between the two support plates 7, the external fixed sleeve of the rotating rod 8 is provided with a clamping roller 9, the outer surface of the clamping roller 9 is covered with a rubber sleeve 10, the sleeves 4 at both ends of the connecting rod 3 are respectively installed on the outside of the corresponding support rod 1, and the sleeve 4 is slidably connected to the support rod 1, the bottom end of the feed screw 5 extends to the bottom of the top plate 2, and is rotatably connected to the connecting rod 3 through a bearing, and the feed screw 5 is threadedly connected to the top plate 2.

[0025] Specifically, this structure can facilitate the clamping and pressing operation of the SBS coil seam alignment part, reducing the burden of the operator to press hard. Specifically, the two support rods 1 are placed on the two SBS coils, and the clamping roller 9 is located directly above the SBS coil seam alignment part;

[0026] The feed screw 5 is driven to rotate by the adjusting disk 6, so that the two ends of the connecting rod 3 are slidably guided on the outside of the support rod 1 through the sleeve 4. The connecting rod 3 drives the clamping roller 9 between the two support plates 7 to extend downward, and the rubber sleeve 10 on the surface of the clamping roller 9 is clamped and pressed on the seam alignment part of the SBS coil. Since the feed screw 5 is threadedly connected to the top plate 2, the upward movement of the clamping roller 9 is restricted during the clamping and pressing of the seam alignment part of the SBS coil. At this time, it is only necessary to push the clamp and make the rubber sleeve 10 on the outside of the clamping roller 9 clamp and press the seam alignment part. There is no need to provide downward pressing force, which reduces the workload.

[0027] In short, this structure rotates the feed screw 5 so that the connecting rod 3 drives the rubber sleeve 10 on the clamping roller 9 to press the seam alignment part of the SBS coil. Due to the thread restriction of the feed screw 5 and the top plate 2, the clamping roller 9 cannot move upward. Therefore, the clamping and pressing of the seam alignment part of the SBS coil can be completed by simply pushing the clamp, without the need for additional pressing force.

[0028] In a specific embodiment, as shown in the attached Figure 2 、 3 As shown, the inner walls of the two support plates 7 are each provided with a rectangular groove 11, a rectangular block 12 is slidingly provided inside the rectangular groove 11, a spring 13 is provided inside the rectangular groove 11 at the top of the rectangular block 12, and the two ends of the spring 13 are respectively connected to the rectangular block 12 and the inner wall of the rectangular groove 11, and the rotating rod 8 is rotatably connected between the two rectangular blocks 12.

[0029] Specifically, in this structure, as the connecting rod 3 drives the clamping roller 9 to continue to extend downward, the rotating rod 8 at the clamping roller 9 will drive the rectangular block 12 to extend upward inside the rectangular groove 11 and squeeze the spring 13. The spring 13 resets after being squeezed, which can make the rubber sleeve 10 on the clamping roller 9 fit tightly against the SBS coil seam alignment part, thereby improving the clamping and pressing effect. By utilizing the rotating rod 8 to rotate between the two rectangular blocks 12, the clamping roller 9 can drive the rubber sleeve 10 to rotate, thereby facilitating the rolling pressing of the SBS coil seam alignment part.

[0030] In a specific embodiment, as shown in the attached Figure 4 As shown, the outer surface of the clamping roller 9 and the inner wall of the rubber sleeve 10 are fixedly attached with Velcro 14 , and the rubber sleeve 10 is detachably connected to the clamping roller 9 via the Velcro 14 .

[0031] Specifically, in this structure, the rubber sleeve 10 can be disassembled and assembled between the Velcro 14 and the clamping roller 9, which makes it easy to replace and clean the rubber sleeve 10 and achieve the purpose of reuse.

[0032] In a specific embodiment, as shown in the attached Figure 1 As shown, a mounting seat 15 is fixedly mounted on the bottom end of each of the two support rods 1 , and a movable ball 16 is rollingly mounted inside the mounting seat 15 .

[0033] Specifically, in this structure, when an operator pushes the clamp, the two support rods 1 can provide smoothness in pushing through the movable balls 16 rolling on the bottom mounting seat 15 .

[0034] Working principle:

[0035] The present application provides a reusable SBS coil seam alignment clamp. In specific use, after multiple SBS coils are laid using a hot melt method, when the seam alignment portion of the SBS coils needs to be clamped and pressed, the operator places two support rods 1 on the two laid SBS coils, and positions the clamping roller 9 directly above the seam alignment portion of the SBS coil. The rotation of the feed screw 5 drives the connecting rod 3 to extend downward, so that the rubber sleeve 10 on the surface of the clamping roller 9 clamps and presses the seam alignment portion of the SBS coil. At this time, the clamping roller 9 is restricted by the thread between the feed screw 5 and the top plate 2 and does not move upward, so that the rubber sleeve 10 on the surface of the clamping roller 9 is tightly pressed against the seam alignment portion of the SBS coil.

[0036] The operator moves the clamp so that the two support rods 1 can be pushed smoothly by the movable balls 16 rolling on the bottom mounting seat 15, and the clamping roller 9 can be rotated between the two rectangular blocks 12 by the rotating rod 8 to clamp and press the SBS coil seam alignment part.

[0037] The rubber sleeve 10 can be disassembled and assembled between the Velcro 14 and the clamping roller 9, which makes it easy to replace and clean the rubber sleeve 10 and achieve the purpose of reuse.

[0038] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.

[0039] The terms "upper", "lower", "left", "right", "middle", etc. used in this specification are only for the convenience of description and are not intended to limit the scope of implementation of the present invention. Changes or adjustments to their relative relationships should be considered as the scope of implementation of the present invention without substantially changing the technical content.
