Description

Technical Field

[0001] The invention relates to the technical field of copper water-stopping construction, and in particular to a copper water-stopping protection device and method for hydraulic concrete construction joints. Background Art

[0002] A copper water stop is arranged at a depth of 15 to 20 cm on the side of the permanent construction joint of hydraulic concrete facing the water surface. The shape of the copper water stop includes a U-shaped nose in the middle and copper water stop flange plates on both sides. The construction quality of the copper water stop plays an important role in ensuring the integrity of the anti-seepage system.

[0003] During the structural concrete construction, one side flange plate of the copper waterstop is first buried in the concrete of the first poured block, and the other side is buried in the concrete when the later poured block is constructed. According to the characteristics of hydraulic concrete construction, the construction interval between the first poured block and the later poured block is relatively long. During this period, the copper waterstop may be damaged and contaminated due to various reasons, making it difficult to repair in the later stage and is not conducive to the anti-seepage effect of the copper waterstop. Therefore, it is necessary to use a protective device to protect the copper waterstop to facilitate subsequent construction work.

[0004] A copper waterstop protection device for hydraulic concrete construction joints disclosed in a patent application with reference publication number CN218813523U, which is a protection space formed by combining and splicing multiple U-shaped frame units, can protect the copper waterstop, avoiding the problem in the prior art that multiple people are required to cooperate with mechanical operations, effectively reducing manpower input, and in addition, the U-shaped foam board can effectively buffer external disturbances to avoid damage to the copper waterstop.

[0005] At present, copper water stop construction mostly adopts wooden boxes, metal frames and other fixed structures for protection. For example, the above copper water stop protection device uses multiple U-shaped frame units to protect the copper water stop. Although it can play a protective effect, each U-shaped frame unit is made of a fixed structure. Therefore, when disassembling, installing and transporting, multiple workers are required to cooperate in installation, which is time-consuming and labor-intensive, increases the difficulty of construction, and is not convenient for subsequent storage and reuse, and the space utilization rate is not ideal.

[0006] At the same time, the above-mentioned copper waterstop protection device does not provide reinforced support for the copper waterstop, which makes the strength of the protection device and the copper waterstop unsatisfactory. The copper waterstop needs to be suspended in the air for a long time and is prone to deformation, settlement and other risks due to external factors, which affects the subsequent construction and requires plastic surgery, increasing the construction workload. Summary of the invention

[0065] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0066] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0067] Embodiment 1: The present invention provides a technical solution: Figure 1 , Figure 2 and Figure 3 As shown, a copper water-stopping protective device for hydraulic concrete construction joints includes a pre-cast concrete 1, a copper water-stopping body 2 is pre-buried in the construction joint area of ​​the pre-cast concrete 1, and further includes:

[0068] like Figure 5 , Figure 6 as well as Figure 7 As shown, multiple folding protection frames are detachably arranged side by side on the first poured concrete 1 to achieve covering and protecting the copper water stop body 2. Multiple folding protection frames are connected end to end to form a whole. Specifically, a U-shaped frame 3 at one end of each folding protection frame is concavely provided with multiple positioning grooves, and a U-shaped frame 3 at the other end of each folding protection frame is convexly provided with multiple positioning plates. The multiple positioning plates can be correspondingly inserted into the multiple positioning grooves to complete locking. At the same time, connecting screws are passed through the positioning plates and the positioning grooves to reinforce adjacent folding protection frames, and threaded through holes matching the connecting screws are provided on the positioning plates. Each folding protection frame is divided into A connecting portion, a plurality of U-shaped frames 3 and a plurality of protective layers 4, wherein the plurality of U-shaped frames 3 and the plurality of protective layers 4 together form a foldable protective body, wherein the protective layers 4 are all made of flexible materials, and specifically, the protective layers 4 are made of one or more of flexible metal cloth, stab-resistant cloth and ultra-high molecular weight polyethylene non-woven cloth, and can complete the protection work while completing the folding and storage, and the U-shaped frame 3 is made of metal material, taking into account good supporting performance, and the plurality of U-shaped frames 3 and the protective layers 4 are jointly unfolded on the connecting portion to form a protective space, and at the same time, the plurality of U-shaped frames 3 and the protective layers 4 complete the folding and storage action through the connecting portion;

[0069] It is worth noting that when a single foldable protective frame is unfolded and subsequently folded and stored: by providing a foldable protective frame, the guide rail 5 is first assembled at a predetermined position of the first poured concrete 1, and then the multiple U-shaped frames 3 are correspondingly slid and snapped into the guide rail 5, and at the same time, the U-shaped frame 3 at the front end of the foldable protective frame is locked with the guide rail 5, and then the installer only needs to pull the U-shaped frame 3 at the rear to move it to unfold it on the guide rail 5 to form protection, and finally the U-shaped frame 3 at the rear of the foldable protective frame is locked with the guide rail 5 to ensure the integrity of the foldable protective frame, and then the corresponding number of foldable protective frames can be assembled in sequence according to the length of the copper water stop body 2, and the adjacent foldable protective frames are locked by the reserved positioning plates and positioning grooves. When disassembling subsequently, the installer only needs to fold and store the multiple U-shaped frames 3, and the overall installation and disassembly saves time and effort, does not require multiple installers to operate, and can be reused, which is convenient for subsequent transportation and reduces construction costs;

[0070] Multiple reinforcing arm mechanisms are arranged at the top and bottom between adjacent U-shaped frames 3 on each folding protective frame, and the strength of the folding protective frame is improved by multiple reinforcing arm mechanisms. Each reinforcing arm mechanism is provided with a locking unit for locking;

[0071] The inner support mechanism is arranged in the folding protection frame to realize the support and reinforcement of the copper water-stop body 2. The inner support mechanism is divided into a top support member and a bottom support member. The top support member and the bottom support member jointly complete the multi-mode common support of the copper water-stop body 2. The top support member can trigger multiple co-locking units to complete the locking operation of the reinforcing arm mechanism;

[0072] The connection part includes:

[0073] like Figure 4 As shown, two guide rails 5 are arranged at intervals on both sides of the copper water stop body 2 to guide the movement of multiple U-shaped frames 3, and a plurality of positioning holes 6 are arranged side by side on one side of each guide rail 5;

[0074] A plurality of connection seats 7, the plurality of connection seats 7 are distributed at intervals on the two guide rails 5, the plurality of connection seats 7 are all connected to the precast concrete 1, and the two guide rails 5 are fixed to the precast concrete 1 through the plurality of connection seats 7. Specifically, the plurality of connection seats 7 are detachably connected to the guide rails 5 through bolts, and the plurality of connection seats 7 are connected to the precast concrete 1 through embedded rods, and the plurality of connection seats 7 can be connected to the precast concrete 1 by expansion bolts or the like;

[0075] A slider 8 is installed at the front end of each U-shaped frame 3, and the slider 8 at the front end of each U-shaped frame 3 is slidably engaged into the guide rail 5, and a threaded groove 9 is opened on the slider 8. The sliders 8 on the U-shaped frames 3 at the head and tail of each folding protection frame can be removably restricted on the guide rail 5. Specifically, a reinforcing screw is passed through the positioning hole 6, and the reinforcing screw passes through the positioning hole 6 and is screwed into the threaded groove 9 to lock the slider 8, so that the U-shaped frames 3 at the head and tail of the folding protection frame are fixed to the guide rail 5 to ensure overall stability. Multiple protective layers 4 are arranged between adjacent U-shaped frames 3, and the space formed by the multiple U-shaped frames 3 is covered by the multiple protective layers 4 to obtain a protective space. Specifically, the protective layer 4 is detachably connected to the U-shaped frame 3 by means of a pressure strip, a bolt and a slot, which is convenient for subsequent replacement and use.

[0076] Embodiment 2: Based on the reinforcing arm mechanism provided in Embodiment 1, this embodiment provides a further technical solution for the reinforcing arm mechanism.

[0077] like Figure 8 and Fig. 9 As shown, the reinforcing arm mechanism comprises:

[0078] The folding plate is arranged between adjacent U-shaped frames 3 to complete the reinforced support of the folding protection frame. The folding plate is divided into a concave seat 10, a No. 1 folding plate 11 and a No. 2 folding plate 12. The No. 1 folding plate 11 is hinged to the side wall of one U-shaped frame 3, and the No. 2 folding plate 12 is correspondingly hinged to the side wall of another U-shaped frame 3. The front ends of the No. 1 folding plate 11 and the No. 2 folding plate 12 are hinged together in the concave seat 10. The adjacent U-shaped frames 3 are reinforced and fixed by unfolding the No. 1 folding plate 11 and the No. 2 folding plate 12, and the folding plate can adapt to the folding storage of the folding protection frame to complete the cooperation of the follower roller;

[0079] It is worth noting that: when the folding protective frame is reinforced with support: by providing a reinforcing arm mechanism, during the unfolding process of the folding protective frame, the No. 1 folding plate 11 and the No. 2 folding plate 12 rotate on the concave seat 10 to complete the follow-up unfolding work, so that the No. 1 folding plate 11, the No. 2 folding plate 12 and the concave seat 10 together form a support arm structure, which can provide reinforced support between adjacent U-shaped skeletons 3, thereby improving the overall strength of the folding protective frame. At the same time, it can be folded subsequently for easy use. By adding a co-locking unit to the folding plate, the co-locking unit is triggered after the top support member contacts the copper water-stop body 2, and the locking groove 13 is designed. The locking rod 20 is normally hidden in the lock. The open area 131 of the fixed groove 13 is triggered by the top support member, pushing the No. 1 piston member 16 to move in the locking chamber 15, pushing the slide seat 18 and the locking rod 20 to slide in the sliding area, and compressing the No. 1 spring 19, driving the two locking rods 20 of the co-locking unit to be inserted into the extension area 132 of the No. 1 folding plate 11 and the No. 2 folding plate 12 respectively, completing the double locking of the No. 1 folding plate 11 and the No. 2 folding plate 12, avoiding the problem of accidental reset of the folding plate member due to external force impact, improving the stability of the operation of the folding protection frame, and after the subsequent top support member is reset, the co-locking unit is reset synchronously, and the locking rod 20 is reset to the open area 131 again, which is convenient for subsequent folding and storage use;

[0080] like Fig.10 As shown, the locking groove 13 is respectively arranged on one side of the No. 1 folding plate 11 and the No. 2 folding plate 12, and the locking work is completed by the locking groove 13 and the co-locking unit. The locking groove 13 is divided into an open area 131 and an extended area 132. The open area 131 is correspondingly opened through the No. 1 folding plate 11 and the No. 2 folding plate 12, and the extended area 132 is correspondingly extended and opened on the No. 1 folding plate 11 and the No. 2 folding plate 12 and communicates with the open area 131, and the extended area 132 and the open area 131 jointly form an L-shaped space, and the size of the open area 131 is larger than the extended area 132, which can complete active avoidance of the co-locking unit;

[0081] like Fig.11 As shown, in the embodiment of the present invention, the co-locking unit includes:

[0082] The assembly platform 14 is arranged at the bottom of the concave seat 10. Locking chambers 15 are installed on both sides of the assembly platform 14. One side of the locking chamber 15 is open. The tails of the two locking chambers 15 are connected and installed with a No. 1 interface. A No. 1 piston member 16 is slidably installed in the locking chamber 15.

[0083] Two locking members are symmetrically arranged on both sides of the bottom of the concave seat 10 and are respectively connected to two No. 1 piston members 16, and the two locking chambers 15 cooperate with the top support member to complete the triggering control of the two locking members, and the active control of the two locking members is respectively completed through the cooperation of the two No. 1 piston members 16 and the locking chamber 15;

[0084] Each locking element includes:

[0085] The extension platform 17 is integrally fixedly arranged at the bottom of the concave seat 10, and a sliding area is opened on the extension platform 17. A sliding seat 18 connected to the co-locking unit is slidably engaged in the sliding area. A No. 1 spring 19 is installed between the sliding seat 18 and the sliding area. The No. 1 spring 19 is used to push the locking rod 20 to move toward the side of the open area 131. Specifically, the sliding seat 18 is connected to the No. 1 piston member 16, and a locking rod 20 is detachably fixedly installed on the upper surface of the sliding seat 18. The locking rod 20 is made of metal material and has good hardness. Under normal circumstances, the locking rod 20 is reset to the side of the sliding area by the No. 1 spring 19. At this time, the locking rod 20 is located in the open area 131. At the same time, the folding panel can avoid the locking rod 20 through the open area 131 during folding and unfolding. The locking rod 20 moves from the open area 131 to the extension area 132 to complete the locking operation of the folding panel.

[0086] Embodiment 3: Based on the internal support mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the internal support mechanism.

[0087] like Fig.13 and Fig.14 As shown, the bottom support member includes:

[0088] The threaded sleeve 21 is detachably arranged at the bottom of the U-shaped frame 3 in the middle of the folding protection frame. The top of the threaded sleeve 21 is open. A threaded rod 22 is installed in the threaded sleeve 21 through threaded engagement. The threaded rod 22 can complete telescopic adjustment in the threaded sleeve 21. A lifting ring 23 is slidably sleeved on the outside of the threaded sleeve 21, and a lifting track cooperating with the lifting ring 23 is opened on the side wall of the threaded sleeve 21, and two lifting rods 24 are symmetrically installed on both sides of the lifting ring 23.

[0089] The first shaft seat 25 is arranged above the threaded sleeve 21, and the bottom of the first shaft seat 25 is connected to the top of the two lifting rods 24, and the bottom of the first shaft seat 25 is rotatably connected to the top of the threaded rod 22. The height adjustment of the first shaft seat 25 is completed by controlling the extension and contraction of the threaded rod 22. A cylindrical magnet 26 is rotatably installed in the first shaft seat 25, and the two ends of the cylindrical magnet 26 are correspondingly rotatably passed through the first shaft seat 25;

[0090] The limiting member is arranged on one side of the first shaft seat 25 to lock the rotation state of the cylindrical magnet 26, and the limiting member cooperates with the supporting member to control the cylindrical magnet 26;

[0091] It is worth mentioning that: when the copper water-stop body 2 is reinforced with internal support: by providing an internal support mechanism, when the folding protective frame is unfolded, first rotate the threaded rod 22 to complete the telescopic adjustment under the restriction of the threaded sleeve 21, push the No. 1 shaft seat 25 and the cylindrical magnet 26 to move, so that the cylindrical magnet 26 is in contact with the lower surface of the copper water-stop body 2 to complete the bottom fixed support, and at the same time, when the folding protective frame is unfolded, the cylindrical magnet 26 can follow the rotation, effectively reducing the resistance of the folding protective frame under the unfolding and folding actions, making the folding and storage smoother. Under normal circumstances, the external threaded area 40 on the control rod 39 is screwed into the threaded groove of the U-shaped skeleton 3, so as to complete the locking of the top support and avoid interference with the unfolding of the folding protective frame.
