Description

Technical Field

[0001] This application belongs to the field of construction tooling technology, and more specifically, relates to a positioning tool for a construction joint steel plate waterstop. Background Technology

[0002] The steel plate waterstop installed in the tunnel's low sidewall is a key structure of the tunnel's waterproofing and drainage system. Its core function is to effectively prevent groundwater from seeping along construction joints or expansion joints through physical barriers and structural design, thus ensuring the waterproof performance of the tunnel structure.

[0003] Specifically, during tunnel construction, the lower sidewalls are poured first, embedding a portion of the steel plate waterstop into the concrete. After the lower sidewalls are completed, the secondary lining arch is poured. At this time, the other part of the steel plate waterstop is poured into the arch concrete, forming a continuous waterproof barrier at the construction joint, thus preventing water penetration.

[0004] In practice, steel plate waterstops are prone to shifting due to the pressure of concrete during pouring, which reduces their waterproofing effect. Utility Model Content

[0005] The purpose of this application is to provide a positioning fixture for steel plate waterstops in construction joints to prevent the steel plate waterstops from moving and improve the waterproofing effect.

[0012] In one possible implementation, an L-shaped positioning plate is provided near the top of the horizontal plate, and the horizontal portion of the positioning plate extends to the outside of the horizontal plate. When the second clamping plate abuts against the positioning plate, the second clamping plate is arranged parallel to the first clamping plate.

[0013] In one possible implementation, the fixed pile is provided with at least two fixing bolts, the fixing plate is provided with a strip-shaped fixing hole, the fixing bolt is inserted into the strip-shaped fixing hole, a fixing nut is screwed onto the fixing bolt, and the fixing plate is clamped by the side wall of the fixed pile and the fixing nut.

[0025] The positioning fixture for the construction joint steel plate waterstop provided in this application is described below.

[0026] Please refer to the following: Figures 1 to 6 The positioning fixture for the construction joint steel plate waterstop includes a steel plate clamp 1, a locking bolt 2, and a fixing pile 3. The steel plate clamp 1 includes a first clamping plate 101 and a second clamping plate 102. The top ends of the first clamping plate 101 and the second clamping plate 102 are hinged. The steel plate to be fixed is inserted between the first clamping plate 101 and the second clamping plate 102. The first clamping plate 101 and the second clamping plate 102 respectively abut against the two sides of the steel plate to be fixed. A fixing connecting plate 105 is provided on the outer side of the first clamping plate 101. The locking bolt 2 passes through the first clamping plate 101 and the second clamping plate 102. The nut of the locking bolt 2 abuts against the outer side of the second clamping plate 102, and the locking nut 201 of the locking bolt 2 can be tightened against the outer side of the first clamping plate 101 due to rotation. The fixing pile 3 is detachably installed on the casting template, and the fixing pile 3 is detachably connected to the fixing connecting plate 105.

[0027] The beneficial effects of the construction joint steel plate waterstop positioning fixture provided in this embodiment are as follows: Compared with the prior art, the construction joint steel plate waterstop positioning fixture provided in this embodiment can firmly clamp the steel plate waterstop between the first clamping plate 101 and the second clamping plate 102 through the hinged cooperation and the tightening design of the locking bolt 2, so as to avoid displacement due to concrete squeezing during pouring. The detachable connection between the fixing pile 3 and the pouring template, as well as the cooperation between the fixing connecting plate 105 and the fixing pile 3, realize the rigid connection between the fixture and the template, ensure the vertical positioning accuracy of the steel plate waterstop at the construction joint, effectively prevent the waterproofing failure caused by displacement, and improve the reliability of the tunnel waterproofing and drainage system.

[0028] Combination Figure 1 , Figure 2 and Figure 4As shown, the first clamping plate 101 is L-shaped, including a horizontally arranged horizontal plate 103 and a vertically arranged vertical plate 104. The horizontal plate 103 is located at the top of the vertical plate 104, and a fixed connecting plate 105 is located on the outside of the vertical plate 104. A connecting rod 106 is provided at the top of the horizontal plate 103, and a hinge shaft 107 is connected to the connecting rod 106. The second clamping plate 102 has multiple hinge rings 108 near the top. The hinge shaft 107 is inserted into the hinge ring 108, and a limit nut 109 is screwed onto the hinge shaft 107. The limit nut 109 abuts against the outside of one of its hinge rings 108.

[0029] The L-shaped structure of the first clamping plate 101 enhances its overall rigidity and prevents deformation during clamping; the cooperation between the connecting rod 106, the hinge shaft 107, and the hinge ring 108 allows the second clamping plate 102 to rotate around the hinge shaft 107, facilitating the quick insertion and removal of the steel plate waterstop; the limiting nut 109 abuts against the hinge ring 108 to prevent the hinge ring 108 from disengaging from the hinge shaft 107 and ensure the stability of the clamping structure.

[0030] Combination Figure 5 As shown, the first clamping plate 101 is provided with a first clearance hole 111, which is a strip-shaped hole; the second clamping plate 102 is provided with a second clearance hole, and the locking bolt 2 passes through the first clearance hole 111 and the second clearance hole.

[0031] The first clearance hole 111 adopts a strip-shaped hole design, which allows the locking bolt 2 to move slightly in the hole. On the one hand, it can adapt to the clamping requirements of waterstops with different thicknesses of steel plates, and on the other hand, it can facilitate the second clamping plate 102 to flip relative to the first clamping plate 101 when the locking bolt 2 is inserted, so as to facilitate the insertion of the steel plate.

[0032] like Figure 1 and Figure 2 As shown, the first clamping plate 101 is provided with a plurality of first clamping posts 112, and the second clamping plate 102 is provided with a plurality of second clamping posts 113. The first clamping posts 112 and the second clamping posts 113 correspond one to one. When the second clamping plate 102 and the first clamping plate 101 are parallel to each other, the first clamping posts 112 abut against the corresponding second clamping posts 113.

[0033] In practical applications, steel plate waterstops often have corners at their top and bottom. This increases the bonding strength between the waterstop and the cast-in-place structure, and also extends the seepage path, improving the waterproofing effect. Therefore, by setting the first clamping post 112 and the second clamping post 113, the corners at the top or bottom of the steel plate waterstop can be avoided, making it easier for the steel plate clamp 1 to clamp and fix the steel plate waterstop.

[0034] like Figure 1 and Figure 3As shown, a limiting plate 114 is provided on the hinge shaft 107. When the outermost hinge ring 108 abuts against the limiting plate 114, the corresponding first clamping post 112 and second clamping post 113 abut against each other. The limiting plate 114 on the hinge shaft 107 cooperates with the hinge ring 108 to form a mechanical limiting structure. When the outermost hinge ring 108 abuts against the limiting plate 114, the first clamping post 112 and the second clamping post 113 abut against each other. This design does not require additional measurement. The alignment of the first clamping post 112 and the second clamping post 113 is achieved through structural limiting, reducing the difficulty of construction operations.

[0035] like Figure 1 and Figure 6 As shown, the second clamping post 113 includes a clamping tube 115, a spring 117, and a post 116. One end of the clamping tube 115 is fixed to the second clamping plate. The spring 117 is disposed inside the clamping tube 115, and one end of the spring 117 is fixed to the second clamping plate. The post 116 is partially slidably disposed inside the clamping tube 115, and the end of the post 116 inserted into the clamping tube 115 is connected to the spring 117. When the spring 117 is in its natural state, the top end of the post 116 abuts against the first clamping post 112.

[0036] As mentioned in the preceding description, when the second clamping plate 102 is parallel to the first clamping plate 101, the first clamping post 112 abuts against the corresponding second clamping post 113. However, once a steel plate is inserted between the first clamping post 112 and the second clamping post 113, the second clamping plate 102 will rotate at a certain angle, causing the top surfaces of the first clamping post 112 and the second clamping post 113 to no longer be parallel. At this point, only one edge of the second clamping post 113 abuts against the steel plate, significantly reducing the friction between the second clamping post 113 and the steel plate. The spring 117 structure allows the post 116 to retract partially into the clamping tube 115 after the steel plate is inserted between the first clamping post 112 and the second clamping post 113. This ensures that the first clamping plate 101 and the second clamping plate 102 remain parallel, the end faces of the first clamping post 112 and the post 116 remain parallel, and the post 116 and the steel plate remain in surface contact, increasing the friction between them. Meanwhile, here, a high-elasticity spring 117 is used. The greater the force used to compress the spring 117, the greater the clamping force of the column 116 and the first clamping column 112 on the steel plate.

[0037] In this embodiment, an L-shaped positioning plate 110 is provided near the top of the horizontal plate 103. The horizontal portion of the positioning plate 110 extends to the outside of the horizontal plate 103. When the second clamping plate 102 abuts against the positioning plate 110, the second clamping plate 102 is arranged parallel to the first clamping plate 101. The positioning plate 110 allows for easy adjustment of the angle between the first clamping plate 101 and the second clamping plate 102 when the locking nut 201 is rotated, until the second clamping plate 102 is parallel to the first clamping plate 101. At this point, the clamping effect of the first clamping post 112 and the second clamping post 113 on the steel plate is optimal.

[0038] like Figure 1 and Figure 2 As shown, the fixed pile 3 is provided with at least two fixing bolts 301, the fixed connecting plate 105 is provided with a strip-shaped fixing hole 118, the fixing bolts 301 are inserted into the strip-shaped fixing hole 118, and the fixing bolts 301 are screwed with fixing nuts 302. The fixing connecting plate 105 is clamped by the side wall of the fixed pile 3 and the fixing nuts 302.

[0039] The fixing bolts 301 on the fixed pile 3 engage with the strip-shaped fixing holes 118 on the fixing plate 105, allowing the fixing plate 105 to slide radially along the bolts. This facilitates adjustment of the tooling's installation position on the template, adapting to the positioning requirements of different construction joints. The fixing plate 105 is clamped to the side wall of the fixed pile 3 by the fixing nuts 302, forming a detachable rigid connection. This ensures the stability of the tooling during pouring and facilitates quick disassembly and reuse after construction. The arrangement of two fixing bolts simultaneously inserted into the strip-shaped fixing holes maintains the angle of the fixing plate 105.

[0040] Specifically, the fixed pile 3 includes an electromagnet 303 and a mounting frame 304. The electromagnet 303 is attracted and fixed on the formwork for pouring. The mounting frame 304 is C-shaped and fixed to the electromagnet 303. The fixing bolts 301 are provided on the outer wall of the mounting frame 304.

[0041] The fixed pile 3 uses a combination of an electromagnet 303 and a C-shaped mounting frame 304. The electromagnet 303 can quickly fix the tooling to the template through magnetic attraction, without the need for drilling or bolt connections, greatly improving installation and disassembly efficiency. The C-shaped mounting frame 304 encloses the electromagnet 303, enhancing its structural strength.

[0042] Finally, the mounting frame 304 includes two horizontal mounting plates 305 and a vertical mounting plate 306 located between the two horizontal mounting plates 305. The inner walls of both the horizontal mounting plates 305 and the vertical mounting plate 306 abut against the outer wall of the electromagnet 303. The switch 307 of the electromagnet 303 extends out through the open end of the mounting frame 304. Adhesive is provided between the inner walls of the horizontal mounting plates 305 and the vertical mounting plate 306 and the electromagnet 303. The top of the horizontal mounting plate 305 extends to the outside of the electromagnet 303. Two auxiliary bolts 308 are connected between the two horizontal mounting plates 305. The auxiliary bolts 308 are located on both sides of the switch 307 of the electromagnet 303, and the auxiliary bolts 308 keep the electromagnet 303 within the mounting frame 304. The mounting frame 304 is provided with clearance holes, through which the cable of the electromagnet 303 extends to the outside of the mounting frame 304.

[0043] The horizontal mounting plate 305 and vertical mounting plate 306 of the mounting frame 304 are fixed to the electromagnet 303 with adhesive and auxiliary bolts 308, forming a multi-dimensional constraint to prevent the electromagnet 303 from shifting or falling off relative to the mounting frame 304 during vibration. The auxiliary bolts 308 are located on both sides of the electromagnet 303 switch 307, which neither affects the operation of the switch 307 nor prevents the electromagnet 303 from being reliably contained within the mounting frame 304. The clearance hole design facilitates the passage of the electromagnet 303 cable, ensuring the reliability of the circuit connection and thus ensuring the continuous and stable operation of the electromagnet 303, improving the overall safety and durability of the fixture.

[0044] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
