Description

Technical Field

[0001] The invention belongs to the technical field of deformation joint treatment, and in particular relates to a drainage and water guiding device for preventing leakage of building deformation joints. Background Art

[0002] In construction projects, expansion joints are functional structures that regulate the deformation of buildings caused by factors such as temperature changes, foundation settlement, and earthquakes. They are widely present in structural parts such as walls, floors, and roofs. However, due to factors such as material aging, construction defects, and structural displacement, expansion joints can easily become weak links for rainwater infiltration. Traditional waterproofing measures often use passive sealing methods such as sealing strips and waterstops. Although they can block water in the short term, long-term exposure to alternating deformation, ultraviolet radiation, and temperature difference stress environments can easily cause the sealing materials to peel off, crack, and other damage, leading to leakage risks. In addition, conventional drainage designs often rely on natural slope diversion. When the structures on both sides of the expansion joint undergo uneven settlement or thermal expansion and contraction, the original drainage path is easily destroyed, and the accumulation of water accelerates the failure of the sealing layer, forming a vicious cycle.

[0003] Although some water-guiding devices exist in the existing technology to intercept and guide water seepage in deformation joints, they generally have problems such as simple structure, poor adaptability, and high maintenance costs. It is difficult to achieve efficient drainage and long-term sealing under dynamic deformation conditions. Therefore, the development of a drainage and water-guiding device that can actively guide accumulated water and adapt to complex deformation is of great significance to improving the reliability of building waterproofing and extending the service life of the structure.

DETAILED DESCRIPTION

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0021] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0022] In the description of the present invention, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0023] Example 1: Reference Figures 1-8, a drainage and water diversion device for preventing leakage from deformation joints of buildings, comprising a building main body 1, a waterstop 2 being provided at the top opening of the deformation joint between two building main bodies 1, and a protective component 3 being provided on the waterstop 2 for fixing and limiting the waterstop 2, and further comprising: a V-shaped guide groove 4, fixedly installed in the deformation joint, and the groove at the bottom of the V-shaped guide groove 4 being arranged in an inclined shape; a retractable connecting tube 5 being installed between the inner side walls of the V-shaped guide groove 4 at equal intervals; an expansion member being arranged on the side wall of the V-shaped guide groove 4; a step-shaped breaking rod 791 being arranged above the V-shaped guide groove 4; when the expansion joint widens, the gas is collected through the telescopic movement of the connecting tube 5 and transported to the expansion member to seal the installation positions on both sides of the V-shaped guide groove 4; when the expansion joint narrows, the breaking rod 791 is moved close to the groove bottom of the V-shaped guide groove 4 through the cooperation of the expansion member and the linkage mechanism.

[0024] In the present invention, a waterstop 2 is provided at the deformation joint between the two building bodies 1, which can provide anti-seepage protection for the deformation joint and prevent rainwater from leaking and foreign matter from entering the deformation joint. In the prior art, since the waterstop 2 is generally made of rubber material, it has good deformation and anti-seepage performance. When the deformation joint expands and contracts due to temperature changes, settlement or vibration, the waterstop 2 remains sealed through elastic deformation, and the protective component 3 provided during use can cover and protect the waterstop 2, which is convenient for people to step on and more beautiful. However, when the waterstop 2 is used for a long time, it will cause flooding in the summer or in some flood seasons. In construction areas where foundation settlement occurs frequently, phase change displacement of deformation joints occurs frequently, which can easily lead to loosening and falling off of the limiting position of the waterstop 2, which in turn causes water to penetrate from the loose parts. In addition, the long-term expansion and contraction deformation performance of the waterstop 2 becomes weak and damaged, which in turn causes leakage and inadequate sealing at the deformation joint. Therefore, a V-shaped guide groove 4 is provided at the bottom of the waterstop 2 in the deformation joint to provide secondary protection for the deformation joint. If there is leaking water or foreign matter, it can be blocked and diverted by the V-shaped guide groove 4 to prevent the seepage water from falling deep into the deformation joint. The bottom groove of the V-shaped guide groove 4 has a slope to intercept the retained water. The water is drained from one end to the other end, preventing water accumulation and effectively reducing its maintenance cost. However, during the leakage process, it flows through the side wall of the building body 1 and is located in the deformation joint, which is prone to cause secondary leakage to the installation part of the V-shaped guide groove 4. For this reason, a connecting cylinder 5 is provided on the V-shaped guide groove 4. When the deformation joint is deformed, the expansion members cooperate with each other to expand the expansion members at both sides of the V-shaped guide groove 4 to block and limit the seal, thereby avoiding continuous leakage of rainwater and improving the sealing effect of the device. When the deformation joint is deformed smaller, the air stored when it is enlarged is discharged through the outlet pipe 63 sprays out, and sprays air flow toward the groove of the V-shaped guide groove 4, which speeds up the water flow in the groove, avoids obstruction of foreign objects in the leaking water, and improves the drainage rate. Under the cooperation of the expansion piece and the linkage component, on the one hand, the structural design can be used to support and limit the waterstop 2 set on the top, to avoid the foreign objects accumulated at the waterstop 2 from being blocked and accelerated to break and tear the waterstop 2 due to the deformation of the expansion joint, thereby extending the service life of the waterstop 2. On the other hand, it can drive the breaking rod 791 to move downward, and break the ice in the groove of the V-shaped guide groove 4 in the cold winter, thereby improving the drainage smoothness of the groove and having strong environmental adaptability.

[0025] Example 2: Reference Figure 7 , which is basically the same as Example 1, and further: the protective component 3 includes a mounting plate 31 fixed to the top surface of the water stop 2 by screws, a U-shaped plate 32 is fixed on one side of the two mounting plates 31, and an opening is provided on the surface of the U-shaped plate 32, and a sliding rod 33 is installed on the two U-shaped plates 32, and a limiting hole 34 is provided on the surface of the sliding rod 33, and a cover plate 35 is attached to the top surface of the mounting plate 31, and a limiting bolt 36 is provided on the cover plate 35, and the limiting bolt 36 is adapted to the limiting hole 34.

[0026] During installation, after the V-shaped guide groove 4 is placed, when the deformation joint is sealed and protected, the water stop strip 2 is first laid at the deformation joint opening, and then the water stop strip 2 is fixed and limited on the top surface of the two building bodies 1 through the installation plate 31, and then the top is covered and protected again through the cover plate 35. In this way, during use, on the one hand, the deformation joint can be beautified and protected, and on the other hand, when the deformation joint is deformed, the protection component 3 can adaptively deform without causing breakage and tearing, thereby reducing maintenance costs. Elastic balls are fixed at both ends of the slide rod 33 and are clamped in the U-shaped plate 32. When the deformation joint is deformed, the slide rod 33 will not break when stretched, thereby improving the stability of the structure. The cooperation of the limiting hole 34 and the limiting bolt 36 facilitates the limiting of the cover plate 35. Through the above-mentioned design scheme, the deformation joint position can be preliminarily protected and blocked, and a certain protection effect can be achieved against obvious foreign matter and rainwater.

[0027] Example 3: Reference Figure 3 、 Figure 4 and Figure 6 , which is basically the same as Example 2, but furthermore: a fixing strip 41 is fixed to the inner wall of the V-shaped guide groove 4, and the slope of the fixing strip 41 is 25°. Air holes 51 are installed on the two side surfaces of the connecting cylinder 5, and a piston 52 is slidably connected to the inner wall of the connecting cylinder 5. A moving rod 53 is fixed to one side of the piston 52, and one end of the moving rod 53 is rotatably connected to a fixing block 57 through a pin. The end of the fixing block 57 is fixedly connected to the inner wall of the V-shaped guide groove 4, and a sealing ring 56 is fixed to the surface of the moving rod 53. One end of the sealing ring 56 is fixed to the inner wall of the connecting cylinder 5. They are fixedly connected, a gas delivery port 55 is provided on one end surface of the moving rod 53, a gas delivery channel 54 is provided inside the moving rod 53, the gas delivery channel 54 is communicated with the gas delivery port 55, one end of the connecting cylinder 5 is connected to the expansion piece, a cavity 61 is provided inside the connecting cylinder 5, an air inlet pipe 62 is fixed on the outer wall of the connecting cylinder 5, a one-way valve is provided at the connection between the air inlet pipe 62 and the connecting cylinder 5, an air outlet pipe 63 is fixed on the bottom surface of the connecting cylinder 5, one end of the air outlet pipe 63 is inclined and curved, and a one-way valve is provided at the connection between the air outlet pipe 63 and the connecting cylinder 5.

[0028] A fixing strip 41 is fixed to the bottom groove of the V-shaped guide groove 4, so that the groove forms a flow ramp, which facilitates the transportation of the trapped water from one end to the other end, thereby realizing the drainage and diversion operation of the water seepage in the expansion joint.

[0029] It should be noted that: in some special areas, the deformation joints of buildings are small but occur frequently. Therefore, this device can also continuously generate power according to the deformation of the building. The foreign matter mentioned here refers to small fine stones and other foreign matter that leaks out. When the deformation joint is deformed, the piston 52 moves. Although the displacement in the piston 52 is small, the air flow coming out of the air outlet pipe 63 is compressed to produce high-speed and fast-ejected air, which has a certain blowing effect. This structure is similar to the common "syringe needle structure". The air outlet pipe 63 adopts a Laval nozzle design. Although the injection stroke is short, it can generate a strong and precise airflow, thereby assisting in blowing the small foreign matter at the bottom of the groove.

[0030] Furthermore, in the design scheme applied for, the bottom of the V-shaped guide groove is inclined and has a ramp structure. When foreign matter accumulates in the groove, the water is driven by the flow of water or the assistance of air flow, combined with gravity, to divert water from one end of the slope at the bottom of the groove to the other end.

[0031] When the deformation joint is deformed and the spacing becomes wider, it is pulled by the two building bodies 1, driving the piston 52 at the end of the moving rod 53 to slide inside the connecting tube 5, thereby squeezing the air inside the connecting tube 5, so that the air is transported to the hose 71 through the air delivery port 55 and the air delivery channel 54, and finally enters the expansion member, thereby using the expansion member to block and limit the V-shaped guide groove 4 and the side installation fixed position of the building body 1, improving the overall sealing effect, and avoiding the deformation joint seepage water flowing to the installation fixed side position of the V-shaped guide groove 4 to cause leakage again. It is suitable for building areas where deformation joints frequently deform, and prevents the leakage area from loosening and causing gaps. When the sealing is not in place and the deformation joint becomes wider, the inside of the cavity 61 draws external air into the cavity 61 through the air inlet pipe 62, collects air and stores energy; when the deformation joint deforms and the spacing becomes narrower, the two building bodies 1 move relative to each other, and then the two pistons 52 move relative to each other inside the connecting tube 5. At this time, the one-way valve at the air inlet pipe 62 is closed, and the compressed air is ejected through the air outlet pipe 63. Since the inclination angle of one end of the air outlet pipe 63 points to the groove of the V-shaped guide groove 4, the foreign matter accumulated in the flow path of the groove of the V-shaped guide groove 4 is blown away by the jet of air flow, and discharged with the accelerated flow of water, thereby improving the smoothness of the diversion and drainage of the device.

[0032] It should be noted that a sealing cover is installed on the air hole 51 to facilitate sealing of the air hole 51, so that the connection between the expansion piece and the connecting tube 5 is in a connected and sealed state. The air hole 51 is designed so that during installation, air is injected into the rod cavity in the connecting tube 5 through the air hole 51, and then the gas is transported to the interior of the airbag 73 through the expansion piece to pre-inflate the airbag 73 so that it is in a relatively full state. When the deformation joint is deformed, the air in the rod cavity in the connecting tube 5 is compressed, thereby forcing the airbag 73 to further expand and improve the sealing effect. The airbag 73 is generally rectangular in shape. When negative pressure is generated in the rod cavity, the gas refluxes, causing the height of the airbag 73 to become lower.

[0033] Example 4: Reference Figure 3 、 Figure 5 and Figure 8 , which is basically the same as Example 3, but furthermore, the expansion member includes a hose 71 connected to the gas delivery channel 54, one end of the hose 71 is fixedly connected to the moving rod 53, and the other end of the hose 71 passes through the inner wall of the V-shaped guide groove 4 and is fixed with an airbag 73, which is embedded in the notch 72, and the notch 72 is opened on the outer wall of the V-shaped guide groove 4. A moving member is provided on the top of the airbag 73, and the moving member includes an extrusion plate 74 attached to the surface of the airbag 73. A lifting rod 75 is fixed on the top of the extrusion plate 74, and the lifting rod 75 is slidably connected to the inner wall of the V-shaped guide groove 4. A chamber 76 is provided inside the V-shaped guide groove 4, and a reset spring 77 is provided on the surface of the lifting rod 75. One end of the reset spring 77 is fixedly connected to the lifting rod 75 through a limit block. The linkage mechanism includes a support frame 79 fixedly connected to the lifting rod 75, and a guide plate 78 is fixed to the top surface of the support frame 79. One side of the guide plate 78 is in contact with the building body 1. The bottoms of multiple support frames 79 are fixedly connected to the breaking rod 791. The V-shaped guide groove 4 is made of highly elastic stainless steel material, and a protective layer is fixed on the inner wall of the V-shaped guide groove 4. The protective layer adopts a super-hydrophobic nano-ceramic coating.

[0034] When the spacing between the deformation joints becomes wider, the fixed edges on both sides of the V-shaped guide groove 4 are pulled loose. At this time, the air in the rod cavity in the connecting tube 5 is compressed and transported to the inside of the airbag 73, causing the airbag 73 to expand, and then the side positions of the V-shaped guide groove 4 are expanded and filled, which has a good secondary protection effect and avoids the problem of looseness and poor sealing performance. When the deformation joint becomes narrower, the negative pressure state of the rod cavity at the connecting tube 5 draws the air in the airbag 73, but the V-shaped guide groove 4 is V-shaped, and the two sides are squeezed, and the fit is tighter, avoiding the occurrence of gaps due to looseness.

[0035] On the other hand, when the airbag 73 expands, the extrusion plate 74 is squeezed, which in turn pushes the lifting rod 75 to slide upward, thereby causing the support frame 79 to move upward as a whole, close to the bottom position of the waterstop 2. The support frame 79 can be used to support and limit the waterstop 2, thereby preventing foreign matter from accumulating on the top of the waterstop 2 for a long time and sagging due to gravity, thereby improving the service life of the waterstop 2 and playing a good supporting role. In addition, one end of the guide plate 78 is fitted with the side change of the building body 1 to guide the leaking water, reduce the flow path, and directly guide the water to the groove of the V-shaped guide groove 4, thereby improving the drainage efficiency, such as in cold winter. In winter, when the deformation joint is deformed and the spacing is shortened, there may be water in the groove of the V-shaped guide groove 4, and ice will form due to the cold weather. As the reset spring 77 is elastically reset, the lifting rod 75 moves down, and the breaking rod 791 installed at the bottom of the support frame 79 moves down synchronously to break the ice in the groove of the V-shaped guide groove 4, which has a good ice-breaking effect and avoids the subsequent accumulation of water caused by ice accumulation, which affects the discharge of seepage water. The environmental applicability of the device is strong, which improves the scope of application of the device. One end of the breaking rod 791 is conical, which is convenient for piercing ice. If rainwater or sewage enters the wall and the V When the gap between the V-shaped guide grooves 4 is formed, one end of the guide plate 78 in the present application is in contact with the side surface of the building body 1 to guide the leaked rainwater or sewage to the bottom of the groove. Although some water may leak again, it will be blocked by the expanded airbag 73. As time goes by, the accumulated water overflows and is guided into the V-shaped guide groove 4 again and guided out. The other end of the return spring 77 is movably connected in the chamber 76, and the extrusion plate 74 is fixed to the outer surface of the airbag 73 by adhesive. When the deformation gap gradually narrows, the extrusion plate 74 is fixed to the outer surface of the airbag 73. The pressure plate 74 is displaced synchronously with the descent of the airbag 73, and the elasticity of the return spring 77 is used to move the lifting rod 75 downward, thereby moving the breaker rod 791 downward to break the ice. The bottom groove of the V-shaped guide groove 4 itself is sloped, and the purpose is to prevent water accumulation at the bottom of the groove. Ice always forms at the bottom of the groove due to environmental reasons, but it is only a thin layer of ice, and no thicker ice layer will be produced. Under the elastic force, the demand can be fully met, so that cracks are produced in the ice layer, the purpose of accelerating the water flow, and ultimately improving the diversion effect of the device.

[0036] The above embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patented invention. It should be noted that those skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention. These variations and improvements are equivalent modifications and improvements to the above embodiments based on the essential technology of the present invention and fall within the scope of protection of the present invention.
