Description

Technical Field

[0001] The invention relates to the field of municipal engineering construction, and in particular to a temporary protective device of a waterproof coiled material at an upwardly turned portion of a main structure bottom. Background Art

[0002] In the process of urban construction and development, the importance of waterproofing of various main structures has become increasingly prominent. During the construction of the main structure, the construction quality of the waterproof membrane at the bottom of the main structure is the focus of the entire waterproof construction control, and it is the prerequisite for ensuring the effective waterproofing of the overall main structure. The existing traditional method is to spray hot melt glue or cold adhesive on the main structure of the upturned part and then lay the waterproof membrane. Later, this part is basically unattended. This method has the following three problems: (1) There are many subsequent construction processes. During the transportation of construction materials, construction workers may accidentally damage or scratch the waterproof membrane in this part. They can only lay an additional layer of waterproof membrane in this part later, which increases labor and material costs; (2) After the concrete of the main structure is poured, watering maintenance will be carried out. This method will cause water caused by human factors or weather reasons to penetrate between the waterproof membrane and the wall, and the seepage is not easy to be found. Over time, the water content of the concrete in this part increases, affecting the bonding effect of the waterproof membrane and the main structure, and easily causing the waterproof membrane to fall off; (3) Since the waterproof membrane in the vertical and horizontal positions is generally upturned by more than 50 cm, it is inconvenient for construction workers to cross. Generally, blocks are placed on site as temporary steps, which affects the construction efficiency of workers. Summary of the Invention

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0025] This embodiment includes an L-shaped support body, and the length of the L-shaped support body is preferably 5-15m. The L-shaped support body needs to be fitted together with the permanent protection wall 1, so the inner width of the L-shaped support body is equal to the width of the permanent protection wall 1, and the inner height of the L-shaped support body is equal to the height of the permanent protection wall 1, so that the L-shaped support body can just be stuck on the vertical wall surface and the upper wall surface of the permanent protection wall 1. The inner here refers to the side close to the permanent protection wall 1, and the inner height of the L-shaped support body includes the height of the roller 9, that is, the vertical distance between the bottom end of the roller 9 and the lower surface of the lower horizontal plate 6, and the inner width includes the thickness of the vertical pressure plate 10, that is, the horizontal distance between the side of the vertical pressure plate 10 close to the main structure and the inner side of the inner vertical plate 4.

[0026] The L-shaped support body of this embodiment includes an outer vertical plate 3, an inner vertical plate 4, an upper horizontal plate 5 and a lower horizontal plate 6 fixed together, wherein the bottoms of the outer vertical plate 3 and the inner vertical plate 4 are fixedly connected together by bottom square wood 7, and the upper horizontal plate 5 and the lower horizontal plate 6 are fixedly connected together by several upper square wood 8. Several rollers 9 are installed at the bottom of the bottom square wood 7 along the length direction of the L-shaped support body, and the rollers 9 enable the device to be moved at any time.

[0027] A number of openings 12 are evenly provided on the outer edge of the upper horizontal plate 5 along the length direction of the upper horizontal plate 5. The openings 12 vertically penetrate the L-shaped support body downward, and a fixing rod 13 is inserted vertically downward into the opening 12. The fixing rod 13 is inserted into the ground to fix the L-shaped support body to prevent it from moving. The fixing rod 13 can be made of a steel chisel or a threaded steel bar nail. In order to facilitate the insertion of the fixing rod 13 into the ground, the bottom of the fixing rod 13 is preferably a pointed cone 18.

[0028] The vertical pressure plate 10 is fixed upwards to the vertical lower horizontal plate 6. The vertical pressure plate 10 is fixed together with the upper horizontal plate 5 and the lower horizontal plate 6, wherein the bottom surface of the vertical pressure plate 10 is flush with the bottom surface of the lower horizontal plate 6. A placement block 11 is fixed on the top of the outer side surface of the vertical pressure plate 10. The placement block 11 is a long strip. The length of the placement block 11 is equal to the length of the L-shaped support body. The top surface of the placement block 11 is flush with the top surface of the vertical pressure plate 10. The placement block 11 is used to place the waterproof membrane to be turned up. The waterproof membrane to be turned up is fixed on the top surface of the placement block 11 by a clamp. A part of the waterproof membrane 21 at the bottom of the main structure 2 is pressed against the vertical wall surface at the bottom of the main structure 2 through the vertical pressure plate 10, and a part is folded onto the top surface of the placement block 11. Because other processes need to be further constructed at the upper position of the bottom of the main structure 2, after the construction of other processes is completed, the waterproof membrane to be turned up on the placement block 11 is turned over to the bottom of the main structure 2 for bottom waterproofing construction. In this embodiment, the clamp is a U-shaped clamp 14, and a threaded hole is provided on the top surface of the U-shaped clamp 14. A bolt 15 is threaded vertically downward in the threaded hole. A straight handle 17 is provided on the top of the bolt 15. The bottom end of the bolt 15 is fixed with a pressing piece 16. By screwing the bolt 15 downward, the pressing piece 16 is pressed against the waterproof membrane to be turned up on the placement block 11.

[0029] To further tighten the waterproof membrane 21 at the upturned portion of the bottom of the main structure 2, a diagonal bracing member is provided between the fixing rod 13 and the placement block 11. The upper and lower ends of the diagonal bracing member respectively support the placement block 11 and the fixing rod 13. Preferably, the diagonal bracing member includes a telescopic rod 19, the upper and lower ends of which are respectively fixed to vertical rectangular blocks 20. The upper vertical rectangular block 20 is tightly pressed against the outer surface of the placement block 11, and the lower vertical rectangular block 20 is tightly pressed against the fixing rod 13.

[0030] When the device of the present invention is used, the device is first pushed to the position of the permanent protection wall 1 at the bottom of the main structure 2, the waterproof membrane at the bottom of the main structure 2 is turned upward, and then the device is pushed to allow the L-shaped support body to be stuck on the permanent protection wall 1, the vertical pressure plate 10 squeezes the turned-up waterproof membrane, and then the roller 9 is braked, and the fixing rod 13 is inserted downward into the opening 12. The fixing rod 13 is inserted into the ground to fix the entire device so that it no longer moves, and then the waterproof membrane reserved for turning up is folded onto the placement block 11, and the waterproof membrane to be turned up is fixed with a U-shaped clip 14. To further enhance the fixing effect, a diagonal bracing member can be placed between the fixing rod 13 and the placement block 11, and the length of the telescopic rod 19 can be adjusted so that the vertical rectangular blocks 20 at the upper and lower ends can be pressed against the placement block 11 and the fixing rod 13, thereby completing the temporary protection of the waterproof membrane 21 at the upward flipped part of the bottom of the main structure 2. Workers can continue to construct other processes. The L-shaped support body can also be used as a temporary walkway, step or simple machine operation platform. After the construction of other processes is completed, remove the U-shaped clamp 14, diagonal bracing member, fixing rod 13, etc., and continue to flip the reserved waterproof membrane to be flipped up to the upper surface of the bottom of the main structure 2, and then overlap it with the waterproof membrane on the upper surface of the bottom of the main structure 2, and then push the device to the next position to continue construction.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
