Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to a connecting device for a waterstop and a connector box and a connecting and peeling method thereof. Background Art

[0002] During the construction of diaphragm walls, the joint shape and pouring of unit wall segments are usually controlled by using a connector box. The connector box can effectively fill the slot space, ensure the smooth lowering of the steel reinforcement cages of adjacent slots, and ultimately guarantee the overall quality and structural stress performance of the wall. To enhance the waterproof effect between adjacent unit wall segments, modern construction techniques also set a special waterstop at the joint between the slot and the connector box. With its excellent elasticity and shrinkage characteristics, this waterstop can effectively block the infiltration of groundwater along the joint into the project interior, achieve reliable sealing and waterproofing, and extend the service life of the engineering building.

[0003] During the construction process, after the concrete pouring is completed, the connector box needs to be lifted out of the slot, and the waterstop needs to be separated from the connector box. Currently, the commonly used separation method is to use construction machinery and equipment to repeatedly push the top of the connector box to peel the waterstop from the connector box. This method has low separation efficiency, and the rubber waterstop may be damaged due to pulling; moreover, since the machinery and equipment only push at the top of the connector box, the pushing effect on the bottom of the connector box is small, and it is relatively difficult to separate the rubber waterstop at the bottom of the connector box from the connector box. In the prior art, to avoid the above situation and the occurrence of the phenomenon that the rubber waterstop at the embedded end comes off from the concrete, a certain length of the rubber waterstop is usually left vacant at the bottom of the connector box, that is, the rubber waterstop is not provided continuously on the connector box. Although this approach can ensure that the rubber waterstop can be separated from the bottom of the connector box, it will weaken the waterproof effect at the bottom of the diaphragm wall.

[0004] In summary, the existing peeling methods all have problems such as uneven peeling force and too dense adhesion between the waterstop and the concrete, increasing the risk of the waterstop being torn and damaged, and may also cause accidental separation of the waterstop and the concrete, affecting the waterproof effect of the diaphragm wall.

[0005] Therefore, there is an urgent need for a connecting device for a waterstop and a connector box and a connecting and peeling method thereof to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a connecting device for a waterstop and a connector box and a connecting and peeling method thereof. The waterstop can not only be quickly connected to the connector box, but also can be smoothly separated from the installation slot before the connector box is pulled out without being pulled, ensuring the waterproof effect of the diaphragm wall while not damaging the waterstop, and significantly improving the separation rate of the waterstop and the connector box.

[0007] To achieve the above object, the present invention adopts the following technical solutions:

[0008] On the one hand, a connecting device between a waterstop and a connector box is provided. An installation groove is provided on the connector box, and the connector box is installed in a groove section. The connecting device between the waterstop and the connector box includes:

[0009] A bracket that can be installed on the guide wall of the diaphragm wall. An installation hole communicating with the groove section is provided on the bracket. Both the connector box and the waterstop can be lowered into the groove section through the installation hole;

[0010] A pushing component is arranged in the installation hole and can contact the first end of the waterstop. When the waterstop is lowered, the pushing component can push the second end of the waterstop into the installation groove;

[0011] A limiting part that can be movably arranged in the installation groove. The limiting part has a construction position where it abuts against the second end of the waterstop and a peeling position away from the second end of the waterstop. In the construction position, the second end of the waterstop can be limited in the installation groove by the limiting part. In the peeling position, the second end of the waterstop can be separated from the installation groove.

[0012] Optionally, the waterstop includes a connected connecting part and a first convex part. The pushing component includes two pushing parts. The two pushing parts are arranged at intervals along the thickness direction of the waterstop. A limiting space is formed between the two pushing parts. The connecting part can be movably penetrated through the limiting space in the vertical direction, and the connecting part is limited in the limiting space along the thickness direction of the waterstop. The first convex part can contact the pushing part.

[0013] Optionally, an installation frame is provided on the hole wall of the installation hole. The pushing part includes a plurality of rollers rotatably arranged on the installation frame. The plurality of rollers are arranged continuously or at intervals along a preset direction. The rollers can contact and roll cooperate with the first convex part. The preset direction gradually approaches the connector box along the direction close to the ground.

[0014] Optionally, the pushing part includes a plurality of pushing portions. The plurality of pushing portions are arranged at intervals along the vertical direction. The pushing portion extends along the width direction of the waterstop and its extension length is adjustable. The lengths of the plurality of pushing portions decrease along the direction away from the ground.

[0015] Optionally, the pushing portion includes a first telescopic rod. One end of the first telescopic rod is connected to the hole wall of the installation hole, and the other end can contact the first convex part;

[0016] Alternatively, the pushing portion includes a pushing rod and a pushing tube. One end of the pushing rod can contact the first convex part, and the other end is located in the inner hole of the pushing tube and is slidably connected to the pushing tube. The end of the pushing tube away from the pushing rod is connected to the hole wall of the installation hole.

[0017] Optionally, the waterstop and joint box connection device further includes a second telescopic rod. One end of the second telescopic rod is hinged to the joint box, and the other end is hinged to the limiting member. When the second telescopic rod expands and contracts, the second telescopic rod can drive the limiting member to rotate around the vertical direction.

[0018] Optionally, the limiting member is a sector-shaped limiting block. The waterstop and joint box connection device further includes a connecting shaft disposed on the joint box. The connecting shaft passes through the center of the sector-shaped limiting block and is rotationally matched with the sector-shaped limiting block. A through hole is provided on the groove wall of the installation groove, and the sector-shaped limiting block is movably inserted through the through hole.

[0019] Optionally, the waterstop and joint box connection device further includes a linear driving member. The linear driving member is disposed on the joint box, and the output end of the linear driving member is connected to the limiting member for driving the limiting member to move in the thickness direction of the waterstop.

[0020] Optionally, a plurality of limiting members are provided on both sides of the installation groove along the thickness direction of the waterstop, and the plurality of limiting members on each side are arranged at intervals in the vertical direction.

[0021] On the other hand, a method for connecting and peeling the waterstop and the joint box is provided. The waterstop and the joint box are connected and peeled using the above-mentioned waterstop and joint box connection device, including the following steps:

[0022] S1. Switch the limiting member to the construction position;

[0023] S2. Lower the waterstop and the joint box together into the groove section through the installation hole. The pushing component contacts the first end of the waterstop and pushes the second end of the waterstop into the installation groove;

[0024] S3. After the concrete pouring is completed, switch the limiting member to the peeling position;

[0025] S4. Lift the joint box out of the groove section through the installation hole, and the second end of the waterstop is separated from the installation groove.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] The present invention provides a device for connecting a waterstop and a joint box and a method for connecting and stripping the same. In the process of lowering the joint box into the slot section, the waterstop is lowered synchronously with the joint box. Even if the limiting member is in the construction position, the second end of the waterstop can enter the installation slot under the pushing action of the pushing assembly to ensure that the waterstop can be connected to the joint box. The operation is convenient and quick, which is helpful for underground engineering construction. After the second end of the waterstop enters the installation slot, the limiting member is in the construction position, so that the limiting member can be stably limited in the installation slot, so as to ensure that the joint between the joint box and the slot section can be effectively blocked by the waterstop during the concrete pouring process, thereby effectively preventing concrete from entering the joint box. After the concrete pouring is completed, the limiting piece is first switched to the stripping position, and the position of the waterstop in the installation groove is no longer constrained. Therefore, when the joint box is lifted out of the groove section, the first end of the waterstop is constrained by the surrounding concrete and cannot move, so that the second end of the waterstop can smoothly detach from the installation groove, and the waterstop is left in the groove section, and the two ends of the waterstop will not be pulled. While ensuring the waterproof effect of the underground continuous wall, the waterstop will not be damaged, and the separation rate of the waterstop and the joint box is significantly improved. The joint box and the waterstop enter the groove section through the installation hole. The hole wall of the installation hole can limit the direction of movement of the joint box and the waterstop, which helps to ensure the accuracy of the lowering position of the joint box. It also allows the waterstop to only enter the installation groove under the push action of the push assembly and will not move in other directions, further ensuring the waterproof effect of the underground continuous wall.

[0045] Embodiment 1

[0046] As Figures 1 to 5 shown, this embodiment provides a connecting device for a waterstop and a joint box. The waterstop 100 can not only be quickly connected to the joint box, but also can be smoothly disengaged from the installation groove 201 before the joint box 200 is pulled out without being pulled, ensuring the waterproof effect of the diaphragm wall while not damaging the waterstop 100, and significantly improving the separation rate of the waterstop 100 from the joint box 200.

[0047] Referring to Figure 1 、 Figure 2 and Figure 4 , an installation groove 201 is provided on the joint box 200, and the joint box 200 is installed in the groove section. The connecting device for the waterstop and the joint box includes a bracket 1, a pushing component 2 and a limiting member 3. The bracket 1 can be installed on the guide wall of the diaphragm wall. An installation hole 11 communicating with the groove section is provided on the bracket 1. Both the joint box 200 and the waterstop 100 can be lowered into the groove section through the installation hole 11. The pushing component 2 is arranged in the installation hole 11 and can contact the first end of the waterstop 100. When the waterstop 100 is lowered, the pushing component 2 can push the second end of the waterstop 100 into the installation groove 201. The limiting member 3 can be movably arranged in the installation groove 201. The limiting member 3 has a construction position where it abuts against the second end of the waterstop 100 and a peeling position away from the second end of the waterstop 100. In the construction position, the second end of the waterstop 100 can be limited in the installation groove 201 by the limiting member 3. In the peeling position, the second end of the waterstop 100 can be disengaged from the installation groove 201. Among them, the first end and the second end are respectively the two ends of the waterstop 100 along its width direction ( Figure 1 the X direction in

[0048] The waterstop and joint box connection device provided in this embodiment is such that, during the process of lowering the joint box 200 into the slot section, the waterstop 100 is lowered synchronously with the joint box 200. Even if the limiter 3 is at the construction position, the second end of the waterstop 100 can enter the installation slot 201 under the pushing action of the push assembly 2 to ensure that the waterstop 100 can be connected to the joint box 200. The operation is convenient and quick, which is helpful for underground engineering construction. After the second end of the waterstop 100 enters the installation slot 201, since the limiter 3 is at the construction position, the limiter 3 can be stably limited in the installation slot 201 to ensure that the joint between the joint box 200 and the slot section can be effectively blocked by the waterstop 100 during the concrete pouring process, thereby effectively preventing concrete from entering the joint box 200. After the concrete pouring is completed, the limiter 3 is first switched to the stripping position, and the position of the waterstop 100 in the installation groove 201 is no longer constrained. Therefore, when the joint box 200 is lifted out of the groove section, the first end of the waterstop 100 is constrained by the surrounding concrete and cannot move, so that the second end of the waterstop 100 can smoothly detach from the installation groove 201, and the waterstop 100 is left in the groove section. The two ends of the waterstop 100 will not be pulled, which ensures the waterproof effect of the underground continuous wall without damaging the waterstop 100 and significantly improves the separation rate of the waterstop 100 and the joint box 200. The junction box 200 and the waterstop 100 enter the groove section through the installation hole 11. The hole wall of the installation hole 11 can limit the movement direction of the junction box 200 and the waterstop 100, which helps to ensure the accuracy of the lowering position of the junction box 200. It also makes the waterstop 100 only able to enter the installation groove 201 under the pushing action of the pushing component 2, and will not move in other directions, further ensuring the waterproof effect of the underground continuous wall.

[0049] In this embodiment, refer to Figure 1 and Figure 4 Bracket 1 utilizes a spatial frame structure, offering strong rigidity and stability, effectively protecting the joint box 200 from damage during lowering or lifting. Bracket 1 has a certain vertical height, allowing mounting hole 11 to also have a certain vertical height, providing ample space for the installation of push assembly 2 and ensuring that waterstop 100 can enter mounting groove 201 after passing through push assembly 2.

[0050] For example, see Figure 4 The cross-sectional shapes of the bracket 1 and the mounting hole 11 are both rectangular, and the mounting hole 11 is located at the center of the bracket 1.

[0051] Optionally, see Figure 3 , Figure 4 and Figure 5, the water stop 100 includes a connected connecting portion 101 and a first protruding portion 102. The pushing assembly 2 includes two pushing members 21. The two pushing members 21 are arranged at intervals along the thickness direction of the water stop 100 ( Figure 4 the Y direction in Figure 1 ). A limiting space is formed between the two pushing members 21. The connecting portion 101 can be movably inserted into the limiting space along the vertical direction ( Figure 3 the Z direction in

[0052] ), and the connecting portion 101 is limited in the limiting space along the thickness direction of the water stop 100. The first protruding portion 102 can contact the pushing member 21. The arrangement of the two pushing members 21 enables a limiting space with a fixed length to be formed between them along the thickness direction of the water stop 100. Thus, when the connecting portion 101 passes through the limiting space along the vertical direction, the displacement of the connecting portion 101 along its thickness direction will be restricted. During the process of lowering the water stop 100, the water stop 100 can only move along the depth direction of the installation groove 201 ( Figure 3 the X direction in

[0052] ) under the pushing action of the pushing member 21, ensuring that the water stop and the joint box 200 can be quickly and effectively connected. In addition, the water stop 100 includes the first protruding portion 102, and the pushing member 21 contacts the first protruding portion 102, enabling the pushing assembly 2 to effectively push the water stop 100 according to the shape of the water stop 100 to ensure the pushing effect of the pushing member 21 on the water stop 100.

[0052] In this embodiment, referring to Figure 1 , Figure 2 and Figure 4 , an installation frame 12 is provided on the hole wall of the installation hole 11. The pushing member 21 includes a plurality of rollers 211 rotatably arranged on the installation frame 12. The plurality of rollers 211 are arranged continuously or at intervals along a preset direction. The rollers 211 can contact and roll cooperate with the first protruding portion 102. The preset direction gradually approaches the joint box 200 along the direction close to the ground. With such an arrangement, the distances of the plurality of rollers 211 from the joint box 200 are different, and the lower the roller 211 is, the smaller the distance from the joint box 200. Thus, during the process of lowering the water stop 100, the pushing forces of the plurality of rollers 211 on the first protruding portion 102 become greater and greater, and the first protruding portion 102 will gradually move towards the direction of the installation groove 201, that is, the second end of the water stop 100 will gradually enter the joint box 200 to complete the connection between the water stop 100 and the joint box 200. In addition, during the process of lowering the water stop 100, the rollers 211 contact the surface of the water stop 100 and roll, which helps to reduce the friction between the rollers 211 and the water stop 100, reduce the wear degree of the water stop 100 caused by the pushing, and ensure the durability of the water stop 100.

[0053] Exemplarily, referring to Figure 1, There are three rollers 211. The cross-sectional shape of the mounting bracket 12 is triangular, which has strong stability and can effectively ensure the position of the roller 211 in the mounting hole 11.

[0054] In other embodiments, the pushing member 21 includes a plurality of pushing portions. The plurality of pushing portions are arranged at intervals in the vertical direction. The pushing portions extend along the width direction of the water stop belt 100 and their extension lengths are adjustable. The lengths of the plurality of pushing portions decrease in the direction away from the ground. With such a setting, the distances between the plurality of pushing portions and the joint box 200 are different, and the distance between the lower pushing portion and the joint box 200 is smaller. Thus, during the process of lowering the water stop belt 100, the pushing forces of the plurality of pushing portions on the first convex portion 102 become larger and larger, and the first convex portion 102 will gradually move towards the installation groove 201, that is, the second end of the water stop belt 100 will gradually enter the joint box 200 to complete the connection between the water stop belt 100 and the joint box 200. In addition, the adjustable length of the pushing portion enables the staff to adaptively adjust the distances between the respective pushing portions and the joint box 200 according to different construction conditions, so as to ensure that the pushing portions can contact the first convex portions 102 of water stop belts 100 with different specifications and push the water stop belt 100 into the installation groove 201, which expands the versatility of the pushing member 21.

[0055] Specifically, the pushing portion includes a first telescopic rod. One end of the first telescopic rod is connected to the hole wall of the mounting hole 11, and the other end can contact the first convex portion 102. By adjusting the telescopic amount of the telescopic rod, the adjustment of the length of the pushing portion can be realized, and the operation is convenient and fast, which is convenient for on-site construction use.

[0056] In some other embodiments, the pushing portion includes a pushing rod and a pushing tube. One end of the pushing rod can contact the first convex portion 102, and the other end is located in the inner hole of the pushing tube and is slidably connected to the pushing tube. The end of the pushing tube away from the pushing rod is connected to the hole wall of the mounting hole 11. By driving the pushing rod to slide relative to the pushing tube, the extension length of the pushing member 21 can be changed, so as to realize the adjustment of the pushing effect of the pushing member 21 on the water stop belt 100, and the operation is convenient and fast, which is convenient for on-site construction use.

[0057] Exemplarily, a sliding groove extending along the axial direction of the pushing rod is provided on the pushing rod, and a sliding block slidably engaged with the sliding groove is provided on the inner wall of the pushing tube to realize the sliding connection between the pushing rod and the pushing tube; at the same time, the groove wall of the sliding groove can limit the circumferential movement of the sliding block along the pushing rod, so that the pushing rod can only move along the extension direction of the pushing tube in the pushing tube and cannot rotate, further ensuring the pushing effect of the pushing member 21 on the water stop belt 100.

[0058] In an alternative embodiment, refer to Figure 2 and Figure 3, the water stop belt and joint box connection device further includes a second telescopic rod 4. One end of the second telescopic rod 4 is hinged to the joint box 200, and the other end is hinged to the limiting member 3. When the second telescopic rod 4 expands and contracts, the second telescopic rod 4 can drive the limiting member 3 to rotate around the vertical direction, so that the limiting member 3 can be switched between the construction position and the peeling position by rotation. The position where the limiting member 3 is switched by rotation, and the second telescopic rod 4 is hingedly connected to the joint box 200 and the limiting member 3, so that when the second telescopic rod 4 drives the limiting member 3 to rotate, the second telescopic rod 4 can adaptively rotate with the limiting member 3 to ensure its driving effect on the limiting member 3.

[0059] Specifically, referring to Figure 2 and Figure 3 , the limiting member 3 adopts a sector-shaped limiting block. The water stop belt and joint box connection device further includes a connecting shaft 5 provided on the joint box 200. The connecting shaft 5 passes through the center of the sector-shaped limiting block and is rotationally matched with the sector-shaped limiting block. A through hole is provided on the wall of the installation groove 201, and the sector-shaped limiting block is movably inserted through the through hole. Compared with a rectangle, when the sector-shaped limiting block rotates, it will not collide with the hole wall of the through hole, ensuring that the position of the limiting member 3 can be smoothly switched, and the joint box 200 will not be damaged due to collision.

[0060] Exemplarily, the second telescopic rod 4 adopts a hydraulic rod and is communicatively connected to a control system on the ground, so that the staff on the ground can control the position of the sector-shaped limiting block at any time. The cross-sectional shape of the sector-shaped limiting block is semi-circular. In the construction position, one hole wall of the through hole can be attached to the plane of the sector-shaped limiting block, and the other hole wall of the through hole can be attached to the arc surface of the sector-shaped limiting block.

[0061] Specifically, a first connecting ear plate is provided on the joint box 200, a second connecting ear plate is provided at one end of the second telescopic rod 4, a third connecting ear plate is provided at the other end of the second telescopic rod 4, and a fourth connecting ear plate is provided on the limiting member 3. The first connecting ear plate and the second connecting ear plate are connected by a first pin shaft, realizing the hinge connection between the joint box 200 and the second telescopic rod 4; the third connecting ear plate and the fourth connecting ear plate are connected by a second pin shaft, realizing the hinge connection between the second telescopic rod 4 and the limiting member 3.

[0062] In another alternative embodiment, the water stop belt and joint box connection device further includes a linear driving member. The linear driving member is provided on the joint box 200, and the output end of the linear driving member is connected to the limiting member 3 for driving the limiting member 3 to move along the thickness direction of the water stop belt 100, so that the limiting member 3 can be switched between the construction position and the peeling position by linear motion.

[0063] Exemplarily, the linear driving member adopts a cylinder or a hydraulic cylinder.

[0064] Optionally, referring to Figure 2 andFigure 3 On both sides of the installation groove 201 along the thickness direction of the waterstop 100, a plurality of limiting members 3 are provided, and the plurality of limiting members 3 on each side are arranged at intervals in the vertical direction. With such a setting, the limiting effect of the installation groove 201 on the waterstop 100 can be significantly improved, ensuring the firmness of the connection between the waterstop 100 and the joint box 200.

[0065] Exemplarily, the length of each joint box 200 is in the range of 10m to 15m, and the distance between two adjacent limiting members 3 in the vertical direction is 1m.

[0066] Embodiment 2

[0067] As Figure 6 shown, this embodiment provides a method for connecting and peeling the waterstop and the joint box. Using the waterstop and joint box connecting device of Embodiment 1 to connect and peel the waterstop 100 and the joint box 200, it includes the following steps:

[0068] S1. Switch the limiting member 3 to the construction position.

[0069] Specifically, referring to Figure 2 and Figure 3 , drive the second telescopic rod 4 to extend. The second telescopic rod 4 pushes against one end of the sector-shaped limiting block, and the sector-shaped limiting block rotates until both the plane and the arc surface of the sector-shaped limiting block are in contact with the hole wall of the perforation, and the limiting member 3 is switched to the construction position.

[0070] Further, before step S1, the following steps are also included: Use a lifting device to move the joint box 200 and the waterstop 100 to the vicinity of the bracket 1 for subsequent construction.

[0071] S2. Lower the waterstop 100 and the joint box 200 together into the groove section through the installation hole 11. The pushing component 2 contacts the first end of the waterstop 100 and pushes the second end of the waterstop 100 into the installation groove 201.

[0072] Specifically, referring to Figure 1 , Figure 2 and Figure 3, before the waterstop 100 moves down to the roller 211, the second protrusion 103 of the waterstop 100 is located on the side of the limiting member 3 away from the installation groove 201, that is, the waterstop 100 is not limited in the installation groove 201, and the connecting portion 101 of the waterstop 100 does not enter the limiting space. When the waterstop 100 moves to the roller 211, the connecting portion 101 enters the limiting space, and the first protrusion 102 gradually contacts the plurality of rollers 211. The plurality of rollers 211 push the first protrusion 102 in sequence from top to bottom, and the first protrusion 102 gradually moves towards the joint box 200. At the same time, the second protrusion 103 is driven by the first protrusion 102 and is squeezed between the limiting member 3 and the groove wall of the installation groove 201 and contacts the limiting member 3, thereby realizing the installation of the waterstop 100 on the joint box 200.
