Description

Technical Field

[0001] The present invention relates to the technical field of building expansion joints, and more specifically, to a waterproof and protective mechanism for building expansion joints and an expansion joint cover plate. Background Art

[0002] With the continuous development of building technology, the scale and complexity of building construction have increased day by day. In building construction, expansion joints are structural joints provided to accommodate factors such as temperature changes, uneven settlement of the foundation, and earthquakes in buildings. They usually exist between different parts of a building, such as between walls and between floors. Their main function is to allow the building to undergo a certain amount of deformation under the influence of various factors without causing damage to the overall structure.

[0003] When a building is subjected to extreme weather or external pressure, water seepage is likely to occur at the expansion joints. For example, during heavy rain, a large amount of rainwater may impact the sealing structure at the expansion joints, causing damage and resulting in water seepage. Currently, to solve the problem of water leakage at building expansion joints, common practices include setting waterstops and sealants at the expansion joints. Waterstops are generally made of rubber or plastic materials and are installed in the expansion joints in the hope of preventing water penetration through their elasticity and sealing properties. Sealants are applied on the surface of the expansion joints to fill the gaps and prevent water from seeping in.

[0004] However, these existing waterproof mechanisms have many obvious defects. On the one hand, during long-term use, waterstops are easily affected by factors such as temperature changes and ultraviolet radiation, resulting in aging, deformation, etc., which leads to a decline in sealing performance and causes leakage problems. On the other hand, although sealants can play a certain waterproof role in the short term, over time, the sealants may crack and fall off. Especially when the expansion joints undergo large deformations, it is inconvenient for the sealants to effectively adapt to the deformations and they are prone to losing their waterproof effects.

[0005] In view of this, the present invention provides a waterproof and protective mechanism for building expansion joints and an expansion joint cover plate. Summary of the Invention

[0006] The purpose of the present invention is to provide a waterproof and protective mechanism for building expansion joints and an expansion joint cover plate to solve the problems raised in the above background art.

[0007] To achieve the above object, the present invention provides a waterproof and protective mechanism for building expansion joints, including a waterproof mechanism. The waterproof mechanism includes two substrates, the substrates are fixedly connected to the inner wall of the building expansion joint, cover plate assemblies are fixedly connected to the tops of the substrates, a support assembly is fixedly connected between the two substrates, a protection assembly is fixedly connected to the top of the support assembly, and both ends of the protection assembly are movably connected to the top of the cover plate assembly;

[0008] The support component is used to provide additional support force for the house wall bodies on both sides. The protection component is used to prevent rainwater seepage and block it. And while the expansion and contraction of the building deformation joint occurs due to temperature changes, it drives the support component to adjust the rainwater diversion angle of the protection component, and at the same time cleans the accumulated water on the cover plate component.

[0009] As a further improvement of this technical solution, the support component includes a rotating groove, the rotating groove is fixedly connected to the outer wall of the substrate, a rotating bead is movably connected inside the rotating groove, a convex rod is fixedly connected to the outer wall of the rotating bead, and a support rod is fixedly connected to the end of the convex rod.

[0010] As a further improvement of this technical solution, a shaft rod is fixedly connected to the outer wall of the support rod near the end. A bracket is movably connected between the ends of the two support rods and the outer wall of the shaft rod, and a protection component is fixedly connected to the top of the bracket.

[0011] As a further improvement of this technical solution, the protection component includes a support rod, the support rod is fixedly connected to the top of the bracket, a rotating shaft is fixedly connected near the top inside the support rod, and two baffle plates are movably connected to the outer wall of the rotating shaft. The two baffle plates are crosswise movably connected to the rotating shaft.

[0012] As a further improvement of this technical solution, a push plate is movably connected to the end of the baffle plate. A long shaft is provided between the push plate and the baffle plate. The long shaft is fixedly connected inside the push plate and movably connected inside the baffle plate. The push plate is movably connected to the top of the cover plate component.

[0013] As a further improvement of this technical solution, the substrate includes two aluminum alloy plates, and a polyethylene core material is provided between the two aluminum alloy plates. The polyethylene core material is a low-density material.

[0014] On the other hand, the present invention also proposes a cover plate for a building deformation joint, which includes a cover plate component. The cover plate component includes a thick plate, the thick plate is fixedly connected between the top of the wall body and the top of the substrate. A thin plate is movably connected inside the thick plate. A slider is fixedly connected to the top of the thin plate, the slider is movably connected inside the thick plate, and a push plate is movably connected to the top of the thick plate. The top of the slider passes through the thick plate and is fixedly connected to the bottom of the push plate.

[0015] As a further improvement of this technical solution, the thick plate is made of stainless steel, and the thin plate is made of rubber.

[0016] Compared with the prior art, the beneficial effects of the present invention:

[0017] 1. In this anti-seepage protection mechanism for building deformation joints, the support component provides additional support force to the building walls on both sides of the deformation joint, preventing the walls from tilting or being damaged due to the structural differences on both sides of the deformation joint, and enhancing the wall stability. Through the triangular structure of the protection component, its unique structural stability enhances the connection strength between the walls. At the same time, the protection component also serves as a barrier to prevent rainwater from penetrating into the building through the deformation joint.

[0018] 2. In this anti-seepage protection mechanism for building deformation joints, under different temperature environments, the building deformation joint will cause thermal expansion and contraction effects due to temperature changes. Thus, the support angle of the support component is adjusted through the expansion and contraction of the building deformation joint, enabling the support component to drive the protection component to adjust the angle, facilitating the adaptive adjustment of the shielding angle of the protection component according to different temperature and weather changes.

[0019] 3. In this anti-seepage protection mechanism for building deformation joints and the deformation joint cover plate, in low-temperature weather, the contraction of the building deformation joint causes the support component to drive the protection component to descend, expanding the apex angle of the protection component, reducing the wind resistance to a certain extent, and ensuring that it is not easily damaged or displaced under strong wind in harsh weather conditions such as snow and wind, thus effectively resisting the invasion of snow and wind to the building. Meanwhile, when moving and expanding, it clears the accumulated water on the cover plate component;

[0020] In high-temperature weather, the expansion of the building deformation joint causes the support component to drive the protection component to rise, reducing the apex angle of the protection component and reducing the coverage area of the protection component on the cover plate component, effectively dispersing the thermal stress of the cover plate component. And when rainwater falls on this kind of cover plate, due to its large slope, the rainwater can flow down along the inclined plane faster, reducing the residence time of rainwater on the cover plate and reducing water accumulation.

[0021] 4. In this deformation joint cover plate of the building, the cover plate component blocks and covers the top of the building deformation joint. And when the apex angle of the protection component expands, it drives the cover plate component to expand and contract, avoiding the appearance of gaps between the deformation joint and the protection mechanism in case of deformation joint contraction during the long-term use of this protection mechanism. The protection length of the deformation joint is expanded through the expansion and extension of the cover plate component. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Embodiment 1

[0038] Please refer to Figures 1 - 3 As shown, the purpose of this embodiment is to provide a waterproof and protective mechanism for building expansion joints, including a waterproof mechanism 1. The waterproof mechanism 1 includes two substrates 11, which are fixedly connected to the inner wall of the building expansion joint. Cover plate assemblies 14 are fixedly connected to the tops of the substrates 11. A support assembly 12 is fixedly connected between the two substrates 11. A protection assembly 13 is fixedly connected to the top of the support assembly 12. Both ends of the protection assembly 13 are movably connected to the top of the cover plate assemblies 14.

[0039] The support assembly 12 is used to provide additional support force to the building walls on both sides. The protection assembly 13 is used to prevent rainwater from seeping and blocking it. At the same time, when the building expansion joint expands and contracts due to temperature changes, it drives the support assembly 12 to adjust the rainwater diversion angle of the protection assembly 13, and at the same time, clears the accumulated water on the cover plate assemblies 14.

[0040] The improvement of this embodiment lies in: providing additional support force to the building walls on both sides of the building expansion joint through the support assembly 12, preventing the wall inclination or damage caused by the structural differences on both sides of the expansion joint, and enhancing the wall stability; through the triangular structure of the protection assembly 13, its unique structural stability enhances the connection strength between the walls. At the same time, the protection assembly 13 also serves as a barrier to prevent rainwater from penetrating into the building through the expansion joint.

[0041] In addition, in different temperature environments, the building expansion joint will be affected by temperature changes and produce thermal expansion and contraction effects. This effect enables the building expansion joint to expand and contract according to temperature changes; and the support assembly 12 can flexibly adjust its own support angle along with the expansion and contraction of the expansion joint; when the temperature rises and the expansion joint expands, the support assembly 12 will correspondingly adjust the angle to adapt to the change of the expansion joint and push the protection assembly 13 to make an angle adjustment; similarly, when the temperature drops and the expansion joint contracts, the support assembly 12 will also make corresponding angle changes to ensure that the protection assembly 13 is always in the best protection position, thereby providing continuous and stable protection for the building.

[0042] First, the specific structure of the support component 12 is disclosed. The support component 12 includes a rotating groove 125 fixedly connected to the outer wall of the substrate 11. A rotating bead 124 is movably connected inside the rotating groove 125. A convex rod 123 is fixedly connected to the outer wall of the rotating bead 124, and a support rod 121 is fixedly connected to the end of the convex rod 123. A shaft rod 122 is fixedly connected to the outer wall of the support rod 121 near the end. A bracket 120 is movably connected between the ends of the two support rods 121 and the outer wall of the shaft rod 122. A protection component 13 is fixedly connected to the top of the bracket 120.

[0043] Refer to Figure 2 , Figure 3 and Figure 5 As shown, the gravity of the protection component 13 exerts a downward pressure on the bracket 120, driving the two support rods 121 to provide pressure on the two side walls of the building expansion joint, thereby enhancing the stability between the two side walls of the building. When the building expansion joint undergoes adaptive changes, it drives the two substrates 11 and the rotating groove 125 to approach or move away from each other, thereby exerting a squeezing or stretching force on the two support rods 121. This force drives the rotating bead 124 to rotate inside the rotating groove 125, adjusting the supporting angle between the convex rod 123 and the support rod 121. At the same time, the shaft rod 122 rotates inside the bracket 120, pushing the bracket 120 to move up and down to adjust the protection function of the protection component 13.

[0044] Refer to Figure 4 As shown, the substrate 11 includes two aluminum alloy plates 110, and a polyethylene core material 111 is provided between the two aluminum alloy plates 110. The polyethylene core material 111 is a low-density material. Through the composition of the two aluminum alloy plates 110 and the middle low-density polyethylene core material 111, due to the good durability and corrosion resistance of the aluminum alloy plates 110, and the polyethylene core material 111 having a low thermal conductivity and the function of effectively preventing heat transfer, the substrate 11 combines the strength of metal and the heat preservation performance of plastic, can insulate the inside of the building wall, improve the waterproof performance of the building wall, and avoid the occurrence of water seepage.

[0045] Secondly, the specific structure of the protection component 13 is disclosed. The protection component 13 includes a support rod 130 fixedly connected to the top of the bracket 120. A rotating shaft 131 is fixedly connected near the top inside the support rod 130. Two baffle plates 132 are movably connected to the outer wall of the rotating shaft 131, and the two baffle plates 132 are movably connected to the rotating shaft 131 in a crosswise manner. The end of the baffle plate 132 is movably connected to a push plate 133. A long shaft 134 is provided between the push plate 133 and the baffle plate 132. The long shaft 134 is fixedly connected inside the push plate 133 and movably connected inside the baffle plate 132. The push plate 133 is movably connected to the top of the cover plate component 14.

[0046] Refer to Figure 2 ,Figure 3 and Figure 6 As shown, the bracket 120 moves up and down, driving the support rod 130 and the rotating shaft 131 to move up and down, and the two baffles 132 are pushed by the support rod 130, so that the baffle 132 rotates between the rotating shaft 131 and the outer wall of the long axis 134, and the baffle 132 drives the push plate 133 to slide on the surface of the cover assembly 14, and the supporting angle of the two baffles 132 between the rotating shaft 131 is adjusted to adapt to the protection conditions of different temperatures and different weathers; and when the push plate 133 slides, the accumulated water on the top of the cover assembly 14 is cleaned.

[0047] On the other hand, the present invention also provides a cover plate for deformation joints of a house, including a cover plate assembly 14, the cover plate assembly 14 includes a thick plate 140, the thick plate 140 is fixedly connected between the top of the wall and the top of the base plate 11, a thin plate 141 is movably connected inside the thick plate 140, a slider 142 is fixedly connected to the top of the thin plate 141, the slider 142 is movably connected inside the thick plate 140, a push plate 133 is movably connected to the top of the thick plate 140, and the top of the slider 142 passes through the thick plate 140 and is fixedly connected to the bottom of the push plate 133.

[0048] See also Figure 2 , Figure 3 and Figure 7 As shown, the push plate 133 moves on the thick plate 140, thereby driving the slider 142 to slide inside the thick plate 140, and the slider 142 moves to push the thin plate 141 to move inside the thick plate 140, and by moving the thin plate 141 out of the thick plate 140, the protection distance of the thick plate 140 for the deformation joint of the house is increased, thereby preventing the formation of a gap between the anti-seepage mechanism 1 and the deformation joint when the anti-seepage mechanism 1 is used for a long time, if the deformation joint shrinks, resulting in liquid penetrating into the deformation joint through the gap;

[0049] The thick plate 140 is made of stainless steel, and the thin plate 141 is made of rubber. Due to the stainless steel material characteristics of the thick plate 140, it has excellent corrosion resistance, heat resistance and strength, and can adapt well to various environmental conditions, including humid and rainy areas. At the same time, its welding performance is good, so that the integrity and sealing of the thick plate 140 are easily guaranteed. According to the rubber material characteristics of the thin plate 141, it has good elasticity and sealing performance, can effectively adapt to deformation, and prevent rainwater from seeping in. When the thin plate 141 is pushed out from the inside of the thick plate 140, the thin plate 141 expands under the action of its own elasticity, increases the width of the thin plate 141, and reduces the size of the gap between the two thin plates 141 when multiple anti-seepage mechanisms 1 are connected. At the same time, when the thin plate 141 is pulled to the inside of the thick plate 140, it can shrink and reset inside the thick plate 140.

[0050] Due to the relatively long overall length of the deformation joint, the existing cover plates usually use welding to connect and extend each group of cover plates, enabling the metal materials between the cover plates to achieve atomic bonding, forming a continuous whole, thereby realizing sealing and fixation, preventing water penetration and displacement of the cover plates; therefore, the connection between each group of thick plates 140 in this solution is also connected by welding, forming an integral waterproof barrier according to the length of the deformation joint to effectively prevent water leakage.

[0051] When the anti-seepage protection mechanism for the building deformation joint and the deformation joint cover plate in this embodiment are specifically used, first, the base plate 11 is fixed on the two building walls on both sides of the building deformation joint by inserting plastic expansion anchor pipes. At the same time, the cover plate assembly 14 is fixed between the building walls of the base plate 11 through plastic expansion anchor pipes, and the push plate 133 and the slider 142 are fixed through plastic expansion anchor pipes;

[0052] Among them, the protection component 13 will exert a downward pressure on the bracket 120 by virtue of its own overall gravity. This downward pressure is further transmitted and will drive the two struts 121 to exert a certain pressure on the building walls on both sides in the deformation joint of the building, effectively enhancing the stability between the two building walls; when the two walls may shake or become unstable due to external factors, the pressure exerted by the struts 121 can play a role in supporting and stabilizing, ensuring that the walls will not easily displace or tilt;

[0053] When the building deformation joint undergoes telescopic changes, the two base plates 11 will drive the two rotating grooves 125 to approach or move away from each other along with the change of the deformation joint; when they approach each other, they will exert a squeezing force on the two struts 121; when they move away from each other, they will exert a pulling force on the struts 121; whether it is the squeezing or pulling force, it will drive the rotating beads 124 to rotate inside the rotating grooves 125, adjusting the supporting angles of the convex rods 123 and the struts 121. Moreover, during this process, the shaft rod 122 will also rotate inside the bracket 120; the rotation of the shaft rod 122 will cause the struts 121 to push the bracket 120 to move up and down, and the up and down movement of the bracket 120 will drive the support rods 130 and the rotating shafts 131 to move up and down;

[0054] The movement of the support rods 130 pushes the two baffles 132, causing the baffles 132 to rotate between the rotating shafts 131 and the outer walls of the long shafts 134; during this rotation, the baffles 132 will drive the push plate 133 to slide on the surface of the cover plate assembly 14; through such a series of actions, the supporting angles of the two baffles 132 between the rotating shafts 131 can be adjusted to meet the protection requirements under different temperatures and weather conditions; and, during the sliding process of the push plate 133, it can also play a role in cleaning the accumulated water on the top of the cover plate assembly 14, avoiding damage to the protection mechanism and the building caused by the accumulated water.

[0055] In addition, when the push plate 133 moves on the thick plate 140, it will drive the slider 142 to slide inside the thick plate 140, and the movement of the slider 142 will further push the thin plate 141 to move inside the thick plate 140. When the thin plate 141 moves out of the thick plate 140, the protection distance of the thick plate 140 for the building deformation joint can be increased. If there may be a gap between the deformation joint shrinkage and the protection mechanism, by increasing the protection distance, it is possible to prevent liquid from penetrating into the deformation joint through this gap, thereby ensuring the sealing performance of the deformation joint and the safety of the building.

[0056] Embodiment 2

[0057] Refer to Figure 2 As shown, in the application of the anti-seepage protection mechanism for building deformation joints and the deformation joint cover plate in this application, in a low-temperature environment, since building materials will shrink due to temperature reduction, the distance between buildings will increase, and the gap of the building deformation joint will also expand accordingly.

[0058] When the building deformation joint shrinks, the distance between the two base plates 11 and the rotating groove 125 will increase accordingly. This change will exert a tensile force on the two support rods 121, causing the rotating beads 124 to rotate inside the rotating groove 125. The rotation of the rotating beads 124 drives the convex rod 123 and the support rod 121 to rotate downward. At the same time, the shaft rod 122 will rotate inside the bracket 120, pushing the bracket 120 to move downward, further driving the support rod 130 and the rotating shaft 131 to also move downward. In this way, the two baffle plates 132 will rotate between the rotating shaft 131 and the outer wall of the long shaft 134 and expand towards both ends. During this process, the two baffle plates 132 will form a triangular structure with a large angle. While reducing the wind resistance to a certain extent, in harsh weather conditions such as snow and wind, this triangular structure with a large angle can ensure that the baffle plates 132 are not easily damaged or displaced under strong wind, thus effectively resisting the invasion of snow and wind on the building.

[0059] Moreover, when the baffle plate 132 rotates, it will also drive the push plate 133 to move outward and expand. The movement of the push plate 133 is used to clean the accumulated water on the surface of the thick plate 140, preventing the accumulated water from damaging the protection mechanism and the building. At the same time, the movement of the push plate 133 will also drive the slider 142 to slide inside the thick plate 140. The slider 142 drives the thin plate 141 to move inside the thick plate 140, and the thin plate 141 is moved out of the thick plate 140, increasing the protection distance of the thick plate 140 applied to the building deformation joint. To prevent, during the long-term use of the anti-seepage mechanism 1, if there is a gap between the deformation joint shrinkage and the protection mechanism, by increasing the protection distance, it is possible to prevent liquid from penetrating into the deformation joint through this gap, ensuring the sealing performance of the deformation joint and the safety of the building.

[0060] Embodiment 3

[0061] Refer toFigure 3 As shown, in the application, during the use of the anti-seepage protection mechanism for building deformation joints and the deformation joint cover plate, in a high-temperature environment, since building materials expand due to the increase in temperature, the distance between buildings decreases, and the gap of the building deformation joint also decreases accordingly.

[0062] When the building deformation joint expands due to external factors, the distance between the two base plates 11 and the rotating groove 125 will decrease accordingly; in this case, an extrusion force will be applied to the two support rods 121, and this extrusion force will cause the rotating beads 124 to rotate inside the rotating groove 125, thereby driving the convex rod 123 and the support rod 121 to rotate upward; at the same time, the shaft rod 122 will rotate inside the bracket 120, and this rotation will push the bracket 120 upward, causing the bracket 120 to drive the support rod 130 and the rotating shaft 131 upward. In this way, the two baffles 132 will rotate between the outer walls of the rotating shaft 131 and the long shaft 134, and during this rotation process, the push plate 133 will be driven to move towards the center; at this time, the two baffles 132 will form a triangular structure with a smaller angle. This structural change reduces the coverage area of the baffle 132 on the thick plate 140 to a certain extent, can effectively disperse the thermal stress of the thick plate 140, and avoid damage to the thick plate 140 caused by thermal stress concentration; moreover, when rainwater falls on the baffle 132 with such a triangular structure with a smaller angle, due to its larger slope, the rainwater can flow down the inclined plane at a faster speed, greatly reducing the residence time of the rainwater on the surface of the baffle 132, thereby effectively reducing the possibility of water accumulation and ensuring the dryness and safety at the building deformation joint.
