Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of deformation joint waterproof structures, and in particular relates to a deformation joint drainage combined anti-seepage construction structure. Background Art
[0002] Deformation joints are a general term for expansion joints, settlement joints and seismic joints. Buildings often deform under the influence of external factors, leading to cracks or even damage. Deformation joints are structural joints reserved for this situation.
[0003] In traditional technology, the treatment method of expansion joints in most designs and constructions is to use simple pre-embedded waterstops or finished metal expansion joint cover plates. However, the simple pre-embedded waterstops have poor waterproofing effects, and the finished expansion joint cover plates have high construction costs and complex construction processes. Both treatments have average effects. Utility Model Content
[0004] The utility model aims to provide a combined anti-seepage construction structure of a deformation joint to solve the problem of poor waterproof effect of the prior art mentioned above.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions: a deformation joint drainage combined anti-seepage construction structure, installed in the deformation joint of the joint structure, the joint structure is in a "convex" shape, including
[0006] The embedded waterstop is located in the deformation joint, and both ends are installed in the joint structure;
[0007] The external water stop is fixed on the top of the joint structure and covers the deformation joint;
[0008] The auxiliary drainage unit includes two drainage components symmetrically arranged about the deformation joint, the drainage component includes a drainage cavity and a drainage pipe, the drainage cavity is opened at the top of the joint structure, the drainage pipe is fixed to the bottom of the drainage cavity, and the bottom edge of the drainage pipe extends below the bottom edge of the joint structure;
[0009] The waterproof unit comprises a cover plate, a waterproof outer plate and a drainage trough pipe, wherein the cover plate is installed on the seam structure and covers the drainage cavity and the top of the external water stop strip, the waterproof outer plate is laid on the outer wall of the cover plate, and the side edge of the waterproof outer plate extends to the corner of the top surface of the seam structure, the drainage trough pipe is installed at the bottom of the seam structure, and the drainage trough pipe is connected with the deformation joint.
[0010] The principle and effect of this technical solution:
[0011] 1. By setting the convex joint structure and the drainage cavity on the side of the deformation joint, the deformation joint is provided with two anti-ridges (anti-ridge is a common term used by the staff in this field and is a commonly known structure. It is only briefly described here. It mainly blocks the flow of water through the vertical wall surface). By setting the two anti-ridges, it is difficult for the accumulated water on the top surface of the joint structure to enter the deformation joint;
[0012] 2. Through the setting of the cover plate and the waterproof outer plate, the deformation joint and the top surface of the drainage cavity are closed, thereby forming a closed waterproof drainage space, that is, the rainwater and water on the outside need to pass through the waterproof outer plate, the cover plate, the drainage cavity, and the external waterstop in turn. At this time, the rainwater penetrates into the deformation joint, passes through the embedded waterstop, and finally enters the drainage trough at the bottom of the deformation joint for discharge. The setting of layers of interception hinders the penetration of water flow and improves the waterproof effect. The "drainage instead of blocking" method of setting a drainage pipe in the drainage cavity further reduces the accumulation of rainwater in the deformation joint, thereby improving the anti-seepage ability of the device.
[0013] 3. By setting two waterstops in the deformation joint, and by setting two anti-ridges and the drainage hole cavity and cover plate sealing, a deformation joint drainage combined structure with multiple defenses and drainage instead of blocking is formed, which can effectively solve the leakage problem of the deformation joint and has a good waterproof effect.
[0014] The utility model is further configured as follows: the cover plate is a concrete plate, and is cast and fixed on the top of the seam structure.
[0015] The principle and effect of this technical solution: The concrete cover plate has many advantages such as high strength and good stability. By setting the cover plate as a cast concrete plate, the cover plate can seal the deformation joint and the drainage cavity stably for a long time, and the sealing effect will not change significantly with changes in the environment, and has good durability.
[0016] The utility model is further configured as follows: the waterproof unit also includes a waterproof inner plate, the waterproof inner plate cover is arranged on the external water stop belt, and the waterproof inner plate extends to fit with the inner wall of the drainage cavity, and the top of the drainage pipe passes through the waterproof inner plate.
[0017] The principle and effect of this technical solution: through the setting of the waterproof inner plate, even if the external rainwater or water flow passes through the waterproof outer plate, the cover plate, and the drainage cavity, the moisture still cannot enter the deformation joint due to the setting of the waterproof inner plate. The water droplets need to continue to pass through the waterproof inner plate before they can penetrate into the deformation joint and then enter the drainage trough pipe. By preventing rainwater from entering the deformation joint, the waterproof and drainage capacity of the structure is further enhanced.
[0018] The utility model is further configured as follows: a mounting groove connected to the deformation joint is opened at the bottom of the seam structure, a drainage groove pipe is fixed in the mounting groove, and the drainage groove pipe is located below the deformation joint, guide rods are respectively fixed at both ends of the drainage groove pipe, and a sliding groove corresponding to the guide rod is opened on the side wall of the mounting groove, and the guide rod is slidably inserted in the sliding groove.
[0019] The principle and effect of this technical solution are as follows: by arranging the drainage trough pipe in the installation groove, the space occupied by the drainage trough pipe on the external space is reduced, and by arranging the guide rod and the slide groove, when the joint structure expands and contracts due to heat, the slide groove can move relative to the guide rod so that the drainage trough pipe can remain stationary relative to the deformation joint and the drainage trough pipe can remain stable, or the guide rod can move relative to the slide groove so that the drainage trough pipe can adapt to the deformation joints and the positions of the joint structures in different sizes.
[0020] The utility model is further configured as follows: a makeshift groove connected to the deformation joint is opened on the top of the seam structure, an external waterstop cover is arranged above the makeshift groove, sealing blocks are fixed on both sides of the inner wall of the makeshift groove, a rubber gasket is fixed between the two sealing blocks, and the tops of the sealing blocks and the rubber gasket are both in contact with the bottom of the external waterstop.
[0021] The principle and effect of the technical solution are as follows: by arranging the sealing block and the rubber gasket, the upper space of the deformation joint is further blocked, and by making the clearance groove larger than the size of the deformation joint, the arrangement of the sealing block and the rubber gasket will not interfere with the normal operation of the deformation joint. At the same time, the elasticity of the rubber gasket can adapt to the size change of the deformation joint, that is, adapt to the size change of the clearance groove, thereby playing a sealing function in real time and improving the waterproof function of the waterproof structure.
[0022] The utility model is further configured as follows: it also includes a sealing plate, which is an aluminum alloy plate, and the sealing plate is installed at the bottom of the give way groove, and the sealing plate cover is arranged above the deformation joint.
[0023] The principle and effect of this technical solution: the setting of the sealing plate further seals the deformation joint, thereby improving the waterproof ability of the device, and the sealing plate is an aluminum alloy plate with good ductility, so that when the seam structure is subjected to thermal expansion and contraction, the sealing plate can deform itself to adapt to the changes in the size of the deformation joint, thereby not hindering the deformation joint from performing its corresponding function.
[0024] The utility model is further configured as follows: fireproof cotton is also installed in the deformation joint, and the fireproof cotton is located above the embedded waterstop.
[0025] The principle and effect of this technical solution: The setting of fireproof cotton can play a certain fire-blocking effect when a fire occurs on the top of the seam structure (or a fire occurs below), thereby preventing the spread of fire. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] As attached Figure 1-4 As shown, the utility model discloses a deformation joint drainage combined anti-seepage construction structure, which is installed in the deformation joint 102 of the joint structure 101. The joint structure 101 is "convex" in shape, including an embedded waterstop 201, an external waterstop 202, an auxiliary drainage unit and a waterproof unit. The top of the joint structure 101 is provided with a clearance groove 103 connected to the deformation joint 102, and the bottom of the joint structure 101 is provided with an installation groove 104 connected to the deformation joint 102. The external waterstop 202 is fixed to the top of the joint structure 101 and covered above the clearance groove 103. Sealing blocks 501 are fixed on both sides of the inner wall of the clearance groove 103, and a rubber gasket 502 is fixed between the two sealing blocks 501. The inner side of the rubber gasket 502 has a spring (such as Figure 4As shown, it is an existing commercially available product and there is no need to elaborate on it. It mainly plays the function of elastic expansion and contraction. Other elastic parts that can play the same role can also be applied to the utility model). The tops of the sealing block 501 and the rubber gasket 502 are both in contact with the bottom of the external waterstop 202. An aluminum alloy sealing plate 503 is also fixed in the clearance groove 103. The middle part of the sealing plate 503 is concave, and the sealing plate 503 is installed at the bottom of the clearance groove 103. The sealing plate 503 covers the top of the deformation joint 102. The concave sealing plate 503 is set to allow a certain amount of rainwater to accumulate and stay there, thereby preventing further penetration of rainwater. The sealing plate 503 is always installed and connected and fixed to both sides of the bottom of the clearance groove 103 by bolts or the like, so that the sealing plate 503 can adapt to the changes of the deformation joint 102.
[0033] The embedded waterstop 201 is located in the deformation joint 102, and both ends are installed in the joint structure 101. During installation, the two wings of the embedded waterstop 201 are respectively buried in the joint structure 101 on both sides for 200mm, and the center of the hole is aligned with the center of the deformation joint 102. The spacing of the embedded waterstop 201 fixed on the steel bar shall not be greater than 400mm. The embedded waterstop 201 is suspended and fixed on the steel bar by a thin iron wire (the steel bar spacing is 2m, and the length is 30cm). During installation, the embedded waterstop 201 is formed into a basin shape to prevent the gas under the embedded waterstop 201 from escaping during concrete pouring and forming pores.
[0034] The convex joint structure 101 needs to be poured in layers during pouring (that is, the anti-step at the top of the deformation joint 102 is poured, and the vertically arranged blocking wall between the joint structure 101 and the deformation joint 102 is the anti-step). First, pour the concrete below the embedded waterstop 201, and the vibrator is continuously and evenly distributed to ensure that there is no vibration leakage, so as to improve the density of the concrete and ensure the density of the lower concrete of the embedded waterstop 201 to meet the design requirements. Secondly, pour the upper concrete of the embedded waterstop 201. During the pouring and vibrating process, the embedded waterstop 201 needs to be protected to prevent the embedded waterstop 201 from moving.
[0035] The auxiliary drainage unit includes two drainage components symmetrically arranged about the deformation joint 102. The drainage component includes a drainage cavity 301 and a drainage pipe 302. The drainage cavity 301 is opened at the top of the seam structure 101. The drainage pipe 302 is fixed to the bottom of the drainage cavity 301, and the bottom edge of the drainage pipe 302 extends to below the bottom edge of the seam structure 101. The drainage pipe 302 needs to be provided with a rubber sealing spherical joint.
[0036] The waterproof unit includes a cover plate 401, a waterproof outer plate 402, a waterproof inner plate 403 and a drainage groove pipe 404. The cover plate 401 is installed on the joint structure 101 and covers the drainage cavity 301 and the upper part of the external water stop 202. The waterproof outer plate 402 is laid on the outer wall of the cover plate 401, and the side of the waterproof outer plate 402 extends to the corner of the top surface of the joint structure 101. The drainage groove pipe 404 is installed at the bottom of the joint structure 101, and the drainage groove pipe 404 is connected with the deformation joint 102. The cover plate 401 is a concrete plate and is cast and fixed on the top of the joint structure 101. The waterproof inner plate 403 The cover is arranged on the external waterstop 202, and the waterproof inner plate 403 extends to fit with the inner wall of the drainage cavity 301, the top of the drain pipe 302 passes through the waterproof inner plate 403, the drainage trough pipe 404 is fixed in the installation groove 104, and the drainage trough pipe 404 is located below the deformation joint 102, and guide rods 405 are fixed at both ends of the drainage trough pipe 404, and the side wall of the installation groove 104 is provided with a slide groove corresponding to the guide rod 405, and the guide rod 405 is slidably inserted in the slide groove, and fireproof cotton 504 is also installed in the deformation joint 102, and the fireproof cotton 504 is located above the embedded waterstop 201.
[0037] The intersection of the external waterstop 202 is custom-made at the waterstop manufacturer, and the on-site joints are bonded by specially trained professionals. After the waterstop is in place, a specially designed U-shaped steel bar fixing clamp is used to clamp its edges and tie it to the structural steel bars to prevent the waterstop from deflecting and tilting during concrete pouring.
[0038] After the pouring of the anti-slope is completed, the top of the joint structure 101 is convex, and at this time, the anti-slope formwork is built and the template is set, and the steel bars are set according to regulations. The steel bars need to be padded with concrete pads to ensure the thickness of the protective layer, and then the concrete can be poured.
[0039] The drainage trough pipe 404 is made of stainless steel, and when setting, each drainage trough pipe 404 is overlapped in sequence, that is, the tail of the previous piece is higher than the head of the next piece, and the overlap length is not less than 100 mm. The starting point of the drainage trough pipe 404 should be slightly higher than the water receiving end to form a certain slope to prevent water collection and diversion. The drainage trough pipe 404 is bonded to the rainwater pipe with waterproof glue to discharge the rainwater in the drainage trough pipe 404 through the rainwater pipe.
[0040] Among them, the first outer anti-ridge is 100mm wide and 130mm high, and the second outer anti-ridge is 200mm wide and 130mm high.
