Description

Technical Field

[0001] The present invention relates to the technical field of waterproof construction of roof drainage ditches. More specifically, the present invention relates to a slip form construction device for a waterproof protective layer of a roof drainage ditch and a method for using the same. Background Art

[0002] Since waterproof coiled materials are provided inside the roof drainage ditch and the construction of the waterproof protective layer is required, but the plastering area inside the ditch is narrow and the comprehensive plastering difficulty is large, resulting in extremely high plastering costs inside the ditch and poor plastering quality, such as unevenness and "two-layer skin" (i.e., the phenomenon of later peeling off). Therefore, a slip form construction device for the waterproof protective layer of the roof drainage ditch is needed for construction operations.

[0003] The invention patent with the patent application publication number CN11677203A discloses a roof waterproof construction device, including a guide rail frame with a length direction arranged horizontally, a sliding frame slidably connected to the guide rail frame along the length direction of the guide rail frame, and a driving mechanism for driving the sliding frame to slide. The sliding frame is provided with a unwinding roller with an axis arranged longitudinally for installing waterproof coiled materials, a pressing roller with an axis direction parallel to the unwinding roller and rotatably connected to the sliding frame for compacting the waterproof coiled materials laid on the roof base layer, a sliding seat reciprocatingly sliding along the axial direction of the unwinding roller, a driving assembly for driving the sliding seat to slide, and a first spray gun and a second spray gun installed on the sliding seat for baking the laying surface of the waterproof coiled materials and the roof base layer respectively. This invention has the effect of effectively improving the uniformity of heating the laying surface of the waterproof coiled materials, thereby improving the roof waterproof effect.

[0004] However, during the use of the above structure, for drainage ditches with different widths, the waterproof construction coverage area of the entire device cannot be adjusted according to the specific width of the drainage ditch, which is not conducive to the construction operation of roof drainage ditches with different model widths. At the same time, only the bottom position of the inner wall of the drainage ditch is waterproofed, and it is difficult to perform synchronous operations at the side positions. Therefore, the construction applicability is poor and it is not convenient to use the device for waterproof construction. Summary of the Invention

[0005] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution significantly different from the prior art. In order to overcome the above-mentioned defects of the prior art, the present invention provides a slip form construction device for a waterproof protective layer of a roof drainage ditch and a method for using the same, so as to solve the problems of performing construction operations on roof drainage ditches with different model widths, and at the same time, only the bottom position of the inner wall of the drainage ditch is waterproofed, and it is difficult to perform synchronous operations at the side positions, so the construction applicability is poor.

[0006] To achieve the above object, the present invention provides the following technical solution: A slip form construction device for the waterproof protective layer of a roof drainage ditch, including an adjustable pulling groove plate, inside which a bidirectional drive screw is installed, and a linkage fine-tuning component is provided outside the bidirectional drive screw;

[0007] The linkage fine-tuning component includes a first threaded collar block and a second threaded collar block arranged outside the bidirectional drive screw. A first bottom bearing plate is fixed to one side of the first threaded collar block. A second bottom bearing plate is installed on one side of the first bottom bearing plate. A first top guide plate is welded to the top end of the first bottom bearing plate. A second top guide plate is installed on one side of the first top guide plate. A linkage stretching component is provided at the inner wall position of the connection between the first top guide plate and the second top guide plate. The first threaded collar block is located on one side of the second threaded collar block. Both the first threaded collar block and the second threaded collar block are threadedly connected to the bidirectional drive screw. The two threads on the outer wall of the bidirectional drive screw are opposite and symmetrically arranged. One end of the bidirectional drive screw penetrates through the inner wall of the adjustable pulling groove plate and extends to the outside of the adjustable pulling groove plate. A gap is formed between the first bottom bearing plate and the second bottom bearing plate, and a gap is formed between the first top guide plate and the second top guide plate.

[0008] Preferably, the linkage stretching component includes an arc-shaped stretching bar provided at the inner wall position of the connection between the first top guide plate and the second top guide plate. Fixed support bars are fixed to both sides of the arc-shaped stretching bar. A rectangular stretching bar is provided on one side of the fixed support bar. Connection blocks are adhesively bonded to both sides of the rectangular stretching bar by hot melt adhesive, and the connection blocks are fixedly connected to the first top guide plate. Push handle brackets are welded to the opposite sides of the first top guide plate and the second top guide plate. A plurality of side rolling support wheels are installed at the bottom ends of the push handle brackets.

[0009] Preferably, a first limit collar support plate is provided on the outer arc surface of the first bottom bearing plate. A second limit collar support plate is installed on the outer arc surface of the second bottom bearing plate. A multi-directional scraping component is installed inside the first limit collar support plate. The multi-directional scraping component includes two adjustment support cylinders installed inside the second limit collar support plate. A sliding pull rod is movably connected inside the cavity of the adjustment support cylinder. A first plastering pressure scraper is welded to one end of the adjustment support cylinder. A second plastering pressure scraper is installed at one end of the sliding pull rod. A bottom plastering scraper is provided between the second plastering pressure scraper and the first plastering pressure scraper and below the adjustment support cylinder. An extended plastering scraper is movably sleeved outside the bottom plastering scraper. The second plastering pressure scraper and the first plastering pressure scraper are symmetrically arranged. The first plastering pressure scraper and the opposite side hanging corner line are both chamfered.

[0010] Preferably, limiting rings are fixed on the opposite sides of the second limiting collar support plate and the first limiting collar support plate. A multi-point extrusion assembly is provided on one side of the limiting ring. The multi-point extrusion assembly includes a linkage extrusion spring provided on one side of the limiting ring, and an extrusion ring is welded to one end of the linkage extrusion spring. Vertical movable rods are fixed to the tops of the extending plastering scraper and the bottom plastering scraper, and the tops of the vertical movable rods penetrate below the second limiting collar support plate and extend to a position above the second limiting collar support plate. A limiting support block with a hexagonal cross-sectional shape is fixed to the top of the vertical movable rod. An extrusion spring is installed outside the vertical movable rod and at the bottom end position of the limiting support block. A fixed ring is provided at the bottom end of the extrusion spring. Two symmetrically arranged collar support blocks are installed on one side of the first bottom bearing plate and above the adjusting pulling groove plate. A groove support rod is movably connected inside each collar support block. A limiting roller is movably connected inside the groove support rod through a bearing. A compression spring is provided outside the groove support rod and on one side of the collar support block.

[0011] A method for using a construction device for the waterproof protective layer of a roof drainage ditch by slip forming is as follows. The specific use steps are as follows:

[0012] Step 1. During linkage pre-adjustment, insert the first bottom bearing plate and the second bottom bearing plate into the inner wall position of the ditch body. According to the width of the roof drainage ditch, rotate the bidirectional drive screw. The bidirectional drive screw drives the first threaded collar block and the second threaded collar block to move in opposite directions under the action of the thread. The first threaded collar block drives the first bottom bearing plate to move, and the second threaded collar block drives the second bottom bearing plate to move. A gap is generated between the first bottom bearing plate and the second bottom bearing plate. At the same time, the first bottom bearing plate drives the first top guide plate to move, and the second bottom bearing plate drives the second top guide plate to move. The two fixed support bars can pull the arc stretching bar, and the arc stretching bar deforms and elongates while fitting on the inner wall parts of the first top guide plate and the second top guide plate. And the two connecting blocks pull the rectangular stretching bar, and the rectangular stretching bar undergoes elastic deformation and elongates. Then the rectangular stretching bar fits on another gap between the second top guide plate and the first top guide plate, and the width of the overall device can be finely adjusted.

[0013] Step 2. During multi-point limiting extrusion, when a large gap is generated between the second bottom bearing plate and the first bottom bearing plate, the first bottom bearing plate can be driven to move the first limiting collar support plate, and the second bottom bearing plate drives the second limiting collar support plate to move. The second limiting collar support plate drives the sliding pull rod to slide out from inside the adjusting support cylinder. At the same time, the sliding pull rod drives the second plastering pressure scraper to move.

[0014] The adjusting support cylinder drives the first plastering pressure scraper to move. The first plastering pressure scraper is extruded at one side position of the inner wall of the drainage ditch, and the second plastering pressure scraper is extruded at the other side position of the inner wall of the drainage ditch. The first plastering pressure scraper extrudes the extrusion ring, causing the linkage extrusion spring to compress on the limiting ring. Under the extrusion force of the linkage extrusion spring, the first plastering pressure scraper and the second plastering pressure scraper generate a certain fitting extrusion force. Moreover, the bottom plastering scraper and the extending plastering scraper are extruded and fitted at the bottom position of the inner wall of the drainage ditch. The vertical movable rod drives the limiting support block to move upward, and the limiting support block drives the extrusion spring to move upward and stretch on the fixed ring. Under the action of the resilience of the extrusion spring, the extending plastering scraper and the bottom plastering scraper are extruded and fitted at the inner wall position of the drainage ditch;

[0015] Step 3: When side guiding and limiting, when the limiting roller is extruded against the inner wall of the drainage ditch, the limiting roller drives the groove rod to move along the inside of the collar block, and the collar block drives the end of the compression spring to stretch. The limiting roller can fit against the inner wall of the drainage ditch and move in a guiding manner by extrusion. The two limiting rollers are respectively fitted at both sides of the drainage ditch;

[0016] Step 4: During the construction of the waterproof protective layer sliding form, the traction device can be hung at the arc position of the adjusting pulling groove plate. The construction worker can hold the pushing handle bracket and push it. Pour the mortar into the position between the second bottom bearing plate and the first bottom bearing plate, and the height of the mortar is at three-fourths of the depth of the first top guide plate. Then move the adjusting pulling groove plate. The adjusting pulling groove plate drives the bidirectional transmission screw rod to synchronize the movement of the first threaded collar block and the second threaded collar block. The first bottom bearing plate and the second bottom bearing plate move, and the first top guide plate and the second top guide plate also move synchronously. Since there are gaps on the sides and bottom of the first bottom bearing plate and the second bottom bearing plate, the mortar will adhere to the bottom end and both sides of the inner wall of the drainage ditch. When moving, the first bottom bearing plate drives the first limiting collar plate to move, and the second bottom bearing plate drives the second limiting collar plate to move. The first limiting collar plate drives the adjusting support cylinder to move the first plastering pressure scraper, and the sliding pull rod moves the second plastering pressure scraper. The bottom plastering scraper and the extending plastering scraper move along the bottom end position of the inner wall of the roof drainage ditch, enabling the first plastering pressure scraper and the second plastering pressure scraper to fit and scrape the mortar in the roof drainage ditch. The second plastering pressure scraper and the bottom plastering scraper can scrape and smear the bottom end of the inner wall of the roof drainage ditch, and thus a waterproof protective layer sliding form can be formed in the roof drainage ditch.

[0017] The technical effects and advantages of the present invention:

[0018] 1. The present invention uses a linkage fine-tuning component to rotate a bidirectional transmission screw rod. The bidirectional transmission screw rod drives the first threaded collar block and the second threaded collar block to move in opposite directions under the action of the threads. The second threaded collar block drives the second bottom loading plate to move, creating a gap between the first bottom loading plate and the second bottom loading plate. The first bottom loading plate drives the first top feeding plate to move, and the second bottom loading plate drives the second top feeding plate to move. The arc-shaped stretching strip deforms and elongates, and the rectangular stretching strip undergoes elastic deformation and elongates. This can finely adjust the width of the overall device, so as to be applicable to roof drainage gutters of different widths, facilitating construction operations on roof drainage gutters of different model widths and being more convenient to use;

[0019] 2. The present invention uses a multi-point extrusion component to enable the second limiting collar support plate to drive the sliding pull rod to slide out from inside the adjusting support cylinder. The first plastering pressure scraper is extruded at one side position of the inner wall of the drainage gutter, and the second plastering pressure scraper is extruded at the other side position of the inner wall of the drainage gutter. The linkage extrusion spring is compressed on the limiting ring. The first plastering pressure scraper and the second plastering pressure scraper generate a certain fitting extrusion force under the extrusion force of the linkage extrusion spring. Under the action of the resilience of the extrusion spring, the extended plastering scraper and the bottom plastering scraper are extruded and fitted at the position of the inner wall of the drainage gutter, achieving all-round extrusion and fitting of the inner wall of the roof drainage gutter. Thus, a stable extrusion and leveling is formed during the scraping and spreading process, and the scraping is less likely to miss the drainage gutter position, eliminating the need for subsequent re-scraping, making the construction more convenient, time-saving and labor-saving;

[0020] 3. The present invention uses a multi-directional scraping component to enable the first bottom loading plate to drive the first limiting collar support plate to move, and the second bottom loading plate to drive the second limiting collar support plate to move. The first limiting collar support plate drives the adjusting support cylinder to move the first plastering pressure scraper. The bottom plastering scraper and the extended plastering scraper move along the bottom end position of the inner wall of the roof drainage gutter, realizing that the first plastering pressure scraper and the second plastering pressure scraper are fitted to scrape the mortar in the roof drainage gutter. The second plastering pressure scraper and the bottom plastering scraper can scrape and spread the bottom end of the inner wall of the roof drainage gutter, forming multi-point synchronous brushing, achieving the construction of the entire part of the inner wall of the drainage gutter in one go and being more convenient to use for one-time forming;

[0021] In summary, through the mutual influence of the above multiple functions, the width of the overall device can be finely adjusted, so as to be applicable to roof drainage ditches of different widths. This is beneficial for construction operations on roof drainage ditches of different model widths, making it more convenient to use. During the scraping and smearing process, a stable extrusion and scraping are formed, and the scraping is not likely to cause the position of the drainage ditch to be not scraped. There is no need for subsequent re-scraping, making the construction more convenient, time-saving and labor-saving. It can achieve the construction of the entire inner wall part of the drainage ditch in one go, and it is more convenient to use and form in one go. In summary, it can be conveniently applicable to the waterproof protective layer slip form construction of roof drainage ditches of different models, forming a one-time multi-point extrusion forming construction, with higher construction efficiency and greater convenience.

[0033] In some embodiments, as shown in the attached Figures 1-4As shown in the figure, the linkage fine-tuning assembly includes a first threaded collar block 3 and a second threaded collar block 4 arranged outside the bidirectional transmission screw 2. One side of the first threaded collar block 3 is fixed with a first bottom mounting plate 5. A second bottom mounting plate 6 is installed on one side of the first bottom mounting plate 5. The top of the first bottom mounting plate 5 is welded with a first top feeding plate 7. A second top feeding plate 8 is installed on one side of the first top feeding plate 7. A linkage stretching assembly is provided at the inner wall position of the connection between the first top feeding plate 7 and the second top feeding plate 8. The linkage stretching assembly includes an arc stretching bar 9 provided at the inner wall position of the connection between the first top feeding plate 7 and the second top feeding plate 8. Fixed support bars 10 are fixed on both sides of the arc stretching bar 9. A rectangular stretching bar 11 is provided on one side of the fixed support bar 10. Connecting blocks 12 are adhesively bonded to both sides of the rectangular stretching bar 11 by hot melt adhesive, and the connecting blocks 12 are fixedly connected to the first top feeding plate 7;

[0034] During the use of this embodiment, the first bottom mounting plate 5 and the second bottom mounting plate 6 are inserted into the inner wall position of the groove body. The bidirectional transmission screw 2 is rotated to drive the first threaded collar block 3 and the second threaded collar block 4 to move in opposite directions under the action of the thread. A gap is generated between the first bottom mounting plate 5 and the second bottom mounting plate 6. At the same time, the first bottom mounting plate 5 drives the first top feeding plate 7 to move, and the second bottom mounting plate 6 drives the second top feeding plate 8 to move. The two fixed support bars 10 can pull the arc stretching bar 9 to fit on the inner wall parts of the first top feeding plate 7 and the second top feeding plate 8. The two connecting blocks 12 pull the rectangular stretching bar 11 to undergo elastic deformation and fit on another gap between the second top feeding plate 8 and the first top feeding plate 7, forming a fine-tuning operation.

[0035] In some embodiments, as shown in the appendix Figures 5-6 As shown in the figure, a first limit collar support plate 15 is provided on the outer wall arc surface of the first bottom mounting plate 5. A second limit collar support plate 16 is installed on the outer wall circular arc surface of the second bottom mounting plate 6. A multi-directional scraping assembly is installed inside the first limit collar support plate 15. The multi-directional scraping assembly includes two adjusting support cylinders 17 installed inside the second limit collar support plate 16. A sliding pull rod 18 is movably connected in the inner cavity of the adjusting support cylinder 17. One end of the adjusting support cylinder 17 is welded with a first plastering pressure scraping plate 19. One end of the sliding pull rod 18 is installed with a second plastering pressure scraping plate 20. A bottom plastering scraping plate 21 is provided between the second plastering pressure scraping plate 20 and the first plastering pressure scraping plate 19 and at the position below the adjusting support cylinder 17. An extendable plastering scraping plate 22 is movably sleeved outside the bottom plastering scraping plate 21. The second plastering pressure scraping plate 20 and the first plastering pressure scraping plate 19 are symmetrically arranged. The first plastering pressure scraping plate 19 and the opposite side hanging corner line are both chamfered;

[0036] During the use of this embodiment, the traction device can be hung at the arc position of the adjusting and pulling groove plate 1. The construction worker's hand can hold the pushing handle bracket 14 to drive the multiple side rolling wheels 13 to roll, and pour the mortar into the position between the second bottom bearing plate 6 and the first bottom bearing plate 5. The height of the mortar is at three-quarters of the depth of the first top guide plate 7. The adjusting and pulling groove plate 1 drives the bidirectional transmission screw 2 to synchronously move the first threaded sleeve ring block 3 and the second threaded sleeve ring block 4, and the first top guide plate 7 and the second top guide plate 8 also move synchronously. Since there are gaps on the sides and bottom of the first bottom bearing plate 5 and the second bottom bearing plate 6, the mortar will adhere to the inner wall bottom end and both sides of the drainage ditch. The first limiting sleeve ring support plate 15 moves and the second limiting sleeve ring support plate 16 moves. The adjusting support cylinder 17 makes the first plastering pressure scraper 19 move, and the sliding pull rod 18 makes the second plastering pressure scraper 20 move. The bottom plastering scraper 21 and the extending plastering scraper 22 move along the inner wall bottom end of the roof drainage ditch. The second plastering pressure scraper 20 and the bottom plastering scraper 21 can scrape and smear the inner wall bottom end of the roof drainage ditch, and a waterproof protective layer sliding film can be formed in the roof drainage ditch.

[0037] In some embodiments, as shown in the attached Figures 7-8 figure, limiting rings 23 are fixed on the opposite sides of the second limiting sleeve ring support plate 16 and the first limiting sleeve ring support plate 15. A multi-point extrusion assembly is provided on one side of the limiting ring 23. The multi-point extrusion assembly includes a linkage extrusion spring 24 arranged on one side of the limiting ring 23, and one end of the linkage extrusion spring 24 is welded with an extrusion ring 25. Vertical movable rods 26 are fixed at the tops of the extending plastering scraper 22 and the bottom plastering scraper 21, and the tops of the vertical movable rods 26 penetrate below the second limiting sleeve ring support plate 16 and extend to a position above the second limiting sleeve ring support plate 16. A limiting support block 30 with a hexagonal cross-sectional shape is fixed at the top of the vertical movable rod 26. An extrusion spring 29 is installed outside the vertical movable rod 26 and at the bottom end position of the limiting support block 30, and a fixing ring 28 is provided at the bottom end of the extrusion spring 29;

[0038] During the use of this embodiment, the first plastering pressure scraper 19 is extruded at one side position of the inner wall of the drainage ditch, and the second plastering pressure scraper 20 is extruded at the other side position of the inner wall of the drainage ditch. The first plastering pressure scraper 19 squeezes the extrusion ring 25 to compress the linkage extrusion spring 24 on the limiting ring 23. The first plastering pressure scraper 19 and the second plastering pressure scraper 20 generate a certain fitting extrusion force under the extrusion force of the linkage extrusion spring 24. The bottom plastering scraper 21 and the extending plastering scraper 22 are extruded and fitted at the inner wall bottom end position of the drainage ditch. The limiting support block 30 drives the extrusion spring 29 to move upward and stretch on the fixing ring 28, realizing the three-sided extrusion of the first plastering pressure scraper 19, the second plastering pressure scraper 20, the bottom plastering scraper 21, and the extending plastering scraper 22.

[0039] In some embodiments, as shown in the attached Figure 3 figure, two symmetrically arranged collar support blocks 31 are installed on one side of the first bottom loading plate 5 and above the adjusting pulling groove plate 1. A groove support rod 32 is movably connected inside each collar support block 31. A limiting roller 33 is movably connected inside the groove support rod 32 through a bearing. A compression spring 27 is provided outside the groove support rod 32 and on one side of the collar support block 31.

[0040] During the use of this embodiment, when the limiting roller 33 is squeezed against the inner wall of the drainage ditch, it drives the groove support rod 32 to move along the inside of the collar support block 31, and the end of the compression spring 27 is stretched. The limiting roller 33 can be pressed and guided to move at the position where it fits against the inner wall of the drainage ditch. The two limiting rollers 33 are respectively fitted against both sides of the drainage ditch to achieve the function of uniform left-right guiding movement.

8. A slip form construction device for a waterproof protective layer of a roof drainage ditch according to any one of claims 1-7, characterized in that, It also includes a usage method of a construction device for the waterproof protective layer sliding form of a roof drainage ditch. The specific usage steps are as follows: Step 1. During the linkage pre-adjustment, insert the first bottom loading plate (5) and the second bottom loading plate (6) into the position of the inner wall of the groove. According to the width of the roof drainage ditch, rotate the bidirectional drive screw (2). The bidirectional drive screw (2) drives the first threaded collar block (3) and the second threaded collar block (4) to move in opposite directions under the action of the thread. The first threaded collar block (3) drives the first bottom loading plate (5) to move, and the second threaded collar block (4) drives the second bottom loading plate (6) to move. A gap is generated between the first bottom loading plate (5) and the second bottom loading plate (6). At the same time, the first bottom loading plate (5) drives the first top guide plate (7) to move, and the second bottom loading plate (6) drives the second top guide plate (8) to move. The two fixed support bars (10) can pull the arc-shaped stretching bar (9). The arc-shaped stretching bar (9) deforms and elongates while fitting on the inner wall parts of the first top guide plate (7) and the second top guide plate (8). And the two connecting support blocks (12) pull the rectangular stretching bar (11). The rectangular stretching bar (11) undergoes elastic deformation and elongates. Then the rectangular stretching bar (11) fits on another gap between the second top guide plate (8) and the first top guide plate (7), and the width of the overall device can be finely adjusted; Step 2. During the multi-point limit extrusion, when a large gap is generated between the second bottom loading plate (6) and the first bottom loading plate (5), the first bottom loading plate (5) can drive the first limit collar support plate (15) to move, and the second bottom loading plate (6) drives the second limit collar support plate (16) to move. The second limit collar support plate (16) drives the sliding pull rod (18) to slide out from inside the adjusting support cylinder (17). At the same time, the sliding pull rod (18) drives the second plastering pressure scraper (20) to move; The adjusting support cylinder (17) drives the first plastering pressure scraper (19) to move. The first plastering pressure scraper (19) is extruded at one side position of the inner wall of the drainage ditch, and the second plastering pressure scraper (20) is extruded at the other side position of the inner wall of the drainage ditch. The first plastering pressure scraper (19) squeezes the extrusion ring (25) to compress the linkage extrusion spring (24) on the limit ring (23). The first plastering pressure scraper (19) and the second plastering pressure scraper (20) generate a certain fitting extrusion force under the extrusion force of the linkage extrusion spring (24). And the bottom plastering scraper (21) and the extended plastering scraper (22) are extruded and fitted at the bottom position of the inner wall of the drainage ditch. The vertical movable rod (26) drives the limit support block (30) to move upward. The limit support block (30) drives the extrusion spring (29) to be stretched upward on the fixed ring (28). Under the action of the resilience of the extrusion spring (29), the extended plastering scraper (22) and the bottom plastering scraper (21) are extruded and fitted at the position of the inner wall of the drainage ditch; Step 3: When laterally guiding and limiting, when the limiting roller (33) presses against the inner wall of the drainage ditch, the limiting roller (33) drives the groove rod (32) to move along the inside of the collar support block (31), and the collar support block (31) drives the end of the compression spring (27) to stretch. The limiting roller (33) can be pressed and guided to move at the position where it fits against the inner wall of the drainage ditch, and the two limiting rollers (33) are respectively fitted at the positions on both sides of the drainage ditch. Step 4: During the construction of the waterproof protective layer sliding formwork, the traction device can be hung at the arc position of the adjustable pulling groove plate (1). The construction worker can hold the pushing handle bracket (14) with his hand to push, and pour the mortar into the position between the second bottom bearing plate (6) and the first bottom bearing plate (5), and the height of the mortar is at three-quarters of the depth of the first top guide plate (7). Then move the adjustable pulling groove plate (1). The adjustable pulling groove plate (1) drives the bidirectional transmission screw rod (2) to synchronously move the first threaded collar block (3) and the second threaded collar block (4). The first bottom bearing plate (5) and the second bottom bearing plate (6) move, and the first top guide plate (7) and the second top guide plate (8) also move synchronously. Since there are gaps on the sides and bottom of the first bottom bearing plate (5) and the second bottom bearing plate (6), the mortar will adhere to the bottom end and both sides of the inner wall of the drainage ditch. When moving, the first bottom bearing plate (5) drives the first limiting collar support plate (15) to move, and the second bottom bearing plate (6) drives the second limiting collar support plate (16) to move. The first limiting collar support plate (15) drives the adjusting cylinder (17) to move the first plastering pressure scraper (19), and the sliding pull rod (18) moves the second plastering pressure scraper (20). The bottom plastering scraper (21) and the extended plastering scraper (22) move along the bottom end position of the inner wall of the roof drainage ditch, so that the first plastering pressure scraper (19) and the second plastering pressure scraper (20) can fit against the inner wall of the roof drainage ditch to scrape the mortar flat. The second plastering pressure scraper (20) and the bottom plastering scraper (21) can scrape and smear the bottom end of the inner wall of the roof drainage ditch, and thus a waterproof protective layer sliding formwork can be formed in the roof drainage ditch.
