Description

Technical Field

[0001] The present invention belongs to the technical field of building exterior wall construction, and particularly relates to a waterproof and seepage-proof structure for building exterior walls. Background Art

[0002] The building exterior wall is an important part of a building. It is not only the peripheral protection structure of the building but also undertakes various functions such as load-bearing, heat insulation, waterproofing, moisture-proofing, noise-proofing, and fire safety.

[0003] In rainy and snowy weather, the building exterior wall can effectively prevent rain and snow from entering the room from around the building to protect the interior from the influence of rainy and snowy weather. However, the outer surface of the building exterior wall is in long-term contact with rain and snow, and is easily eroded by rain and snow, resulting in a decline in its own waterproof and seepage-proof effect. Furthermore, it may lead to leakage of the building exterior wall, and may even affect the load-bearing effect of the building exterior wall, thus affecting the safety of the building.

[0004] In the prior art, generally, a protective layer with waterproof and seepage-proof effects is constructed on the outer surface of the building exterior wall to improve the waterproof and seepage-proof performance of the building exterior wall, such as waterproof coiled materials, waterproof coatings, waterproof films, etc. However, after the building exterior wall blocks rain and snow, rain and snow also have a certain erosion effect on the protective layer on its surface, and the erosion effect of rain and snow on the protective layer is prone to concentrate at the bottom of the protective layer, making the bottom of the building exterior wall still prone to leakage.

[0005] Therefore, there is an urgent need for a structure that can effectively improve the waterproof and seepage-proof performance of building exterior walls. Summary of the Invention

[0006] The purpose of the present invention is to overcome the above problems existing in the traditional technology, and provide a waterproof and seepage-proof structure for building exterior walls, which can effectively improve the waterproof and seepage-proof performance of building exterior walls, and at the same time can effectively reduce the erosion of rain and snow on the building exterior wall.

[0007] To achieve the above technical purposes and reach the above technical effects, the present invention is realized through the following technical solutions: The present invention provides a waterproof and seepage-proof structure for building exterior walls. This waterproof and seepage-proof structure for building exterior walls is constructed on a wall, and includes a plurality of preset devices and a plurality of waterproof devices. A protective layer is constructed on the outer surface of the wall. The plurality of preset devices are evenly distributed at equal intervals in the vertical direction on the wall, and the plurality of waterproof devices correspond to the plurality of preset devices one by one; The preset device includes an embedded part, a rotating part and a plurality of elastic parts; the embedded part is embedded in the wall, an extension part extends outward from the embedded part, and the extension part passes through the wall and the protective layer; the rotating part is rotatably connected with the extension part, and the rotation axis of the rotating part is horizontal and parallel to the outer surface of the wall; the two ends of the elastic part are respectively connected with the rotating part and the extension part, and have a tendency to drive the rotating part to rotate in a direction close to the wall; The waterproof device comprises a waterproof plate and a first waterproof member; the waterproof plate is arranged on the rotating member and is located on a side of the rotating member away from the wall; the first waterproof member is elastic and is arranged at one end of the waterproof plate; The waterproof board can maintain an inclined state under the action of the elastic member, the end of the waterproof board close to the wall is an inclined upper end, and the waterproof board is maintained against the protective layer through the first waterproof member.

[0008] By adopting the above technical solution, in rainy and snowy weather, rain and snow on the outside of the wall can fall along the protective layer or directly onto the waterproof board, and then fall along the waterproof board at a certain distance from the protective layer, thereby effectively reducing the probability of rain and snow contacting the protective layer, and thus effectively improving the waterproof and anti-seepage performance of the building's exterior wall; at the same time, the first waterproof component and the protective layer are offset against each other, which can effectively reduce the probability of rain and snow passing through the gap between the waterproof board and the protective layer along the protective layer, and after the first waterproof component is corroded, it can still maintain the offset with the protective layer under the action of the elastic component.

[0009] Optionally, the waterproof device further includes a second waterproof member; The second waterproof component is elastic, and is disposed above the extending portion. Two ends of the second waterproof component are respectively in contact with and abut against the protective layer and the rotating component.

[0010] By adopting the above technical solution, when rain and snow pass through the gap between the protective layer and the first waterproof component, the second waterproof component can effectively prevent rain and snow from continuing to move downward along the protective layer, so that the rain and snow falling on the second waterproof component leave from both sides. At the same time, the probability of rain and snow entering the gap between the embedded part and the wall can be reduced, thereby further effectively reducing the probability of rain and snow contacting the protective layer.

[0011] Optionally, the first waterproof component and the second waterproof component each have a plurality of deformation holes inside for facilitating elastic deformation thereof.

[0012] By adopting the above technical solution, the first waterproof component and the second waterproof component can be deformed in time under the action of the elastic component after being corroded and deformed, so that the first waterproof component and the second waterproof component can maintain their own effect of reducing the probability of rain and snow contacting the protective layer.

[0013] Optionally, openings are formed at both ends of the corresponding first waterproof member or both ends of the second waterproof member along the direction of the rotation axis of the rotating member for the deformation holes.

[0014] By adopting the above technical solution, when the first waterproof member and the second waterproof member are eroded and the deformation holes are exposed, the rain and snow entering the deformation holes can leave from both sides through the openings, so that the probability of the rain and snow staying on the first waterproof member and the second waterproof member for a long time and causing aggravated erosion can be effectively reduced, and the service life of the first waterproof member and the second waterproof member can be prolonged.

[0015] Optionally, one end of the waterproof plate away from the first waterproof member has a guiding portion, the extending direction of the guiding portion is an arc, and the arc opening of the guiding portion faces the wall.

[0016] By adopting the above technical solution, the tendency of the rain and snow to directly fall on the lower inclined end of the waterproof plate and drive the rotating member to rotate against the acting force of the elastic member can be reduced, so that the reliability of the waterproof device to stably achieve the waterproof effect during use can be improved.

[0017] Optionally, one end of the guiding portion away from the corresponding first waterproof member has a protection structure for reducing collision damage.

[0018] By adopting the above technical solution, the probability of a person being injured by colliding with the lower inclined end of the waterproof plate when moving outside the wall can be reduced, and the safety during the use of the waterproof device can be improved.

[0019] Optionally, the distance between the lower inclined end of the waterproof plate and the rotation axis of the rotating member is less than the distance between the upper inclined end of the waterproof plate and the rotation axis of the rotating member.

[0020] By adopting the above technical solution, the tendency of the rain and snow to directly fall on the lower inclined end of the waterproof plate and drive the rotating member to rotate against the acting force of the elastic member can be further reduced, so that the reliability of the waterproof device to stably achieve the waterproof effect during use can be further improved.

[0021] Optionally, it further includes a splash-proof platform; The splash-proof platform is arranged at the bottom of the wall and on the outer side of the wall. A groove for collecting rain and snow is formed on the splash-proof platform. The opening of the groove faces upward, and the lower inclined end of the waterproof plate is aligned with the opening of the groove in the vertical direction.

[0022] By adopting the above technical solution, the rain and snow falling along the waterproof plate can fall into the groove, so that the probability of the rain and snow splashing to the protective layer after falling to the ground and causing concentrated erosion at the bottom of the protective layer can be reduced.

[0023] Optionally, the top of the splash guard platform is provided with a splash guard. The splash guard is located at the top of the groove, and an entrance communicating with the groove is formed on the side of the splash guard away from the wall. The top of the splash guard has a guiding surface, and the end of the guiding surface away from the wall is an inclined lower end.

[0024] By adopting the above technical solution, the splash guard can further effectively prevent rain and snow falling into the groove from splashing, thereby effectively reducing the impact of rain and snow splashing on the waterproof and anti-seepage performance of the building exterior wall. Moreover, the rain and snow falling on the top of the splash guard can smoothly enter the groove through the entrance, ensuring the collection effect of the groove on the falling rain and snow.

[0025] Optionally, a plurality of drain holes are formed at one end of the splash guard platform away from the wall. Both ends of the drain holes communicate with the groove and the space on the side of the splash guard platform away from the wall respectively.

[0026] By adopting the above technical solution, it is convenient to timely drain the rainwater and snowmelt collected in the groove, and discharge it to the ground far away from the building exterior, thereby further effectively reducing the impact of the discharged rainwater and snowmelt on the waterproof and anti-seepage performance of the building wall.

Detailed Embodiments

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] An embodiment of the present application discloses a waterproof and anti-seepage structure for a building exterior wall, which is constructed on the outermost wall of the building and can effectively reduce the influence of rain and snow erosion on the exterior wall in rainy and snowy weather, thereby effectively improving the waterproof and anti-seepage performance of the building exterior wall.

[0031] Refer to Figure 1 and Figure 2 The waterproof and anti-seepage structure of the building exterior wall includes a plurality of preset devices 3, a plurality of waterproof devices 4, and a splash guard 5, and the plurality of preset devices 3 correspond to the plurality of waterproof devices 4 one by one. Among them, the preset device 3 is used to facilitate the installation of the corresponding waterproof device 4; the waterproof device 4 can effectively reduce the probability of rain and snow contacting the building exterior wall; the splash guard 5 can reduce the probability of rain and snow splashing onto the building exterior wall after falling to the ground and concentrating on the bottom of the building exterior wall for erosion.

[0032] A protective layer 2 with waterproof and anti-seepage effects and rain and snow erosion resistance effects is constructed on the outer surface of the wall 1. In this embodiment, it is preferably that the protective layer 2 is formed by uniformly applying waterproof coating on the outer surface of the wall 1; since the waterproof coating is a prior art in this field, its specific type is not further limited here, and the protective layer 2 is only briefly shown in the drawings.

[0033] The preset device 3 is installed on the wall 1 in a state where its length direction is horizontal, and the plurality of preset devices 3 are equally spaced along the vertical direction on the wall 1.

[0034] Refer to Figure 2 and Figure 3 The preset device 3 includes an embedded part 31, a rotating part 32, and a plurality of elastic parts 33.

[0035] The embedded part 31 is integrally embedded and installed inside the wall 1, and the embedded part 31 extends an extension part 311 toward the outside of the wall 1 along the direction perpendicular to the outer surface of the wall 1, and the extension part 311 penetrates through the wall 1 and also penetrates through the protective layer 2.

[0036] The extension part 311 is integrally in a rectangular plate-like structure, the extension direction of the extension part 311 is its own width direction, and the length direction of the extension part 311 is horizontal.

[0037] The rotating member 32 is integrally in the shape of a rectangular plate. One end of the rotating member 32 in the width direction is rotatably connected to the end of the extending portion 311 away from the wall body 1. The other end of the rotating member 32 in the width direction is located above the extending portion 311, and the rotation axis of the rotating member 32 is parallel to the length direction of the extending portion 311.

[0038] The elastic member 33 is installed at the rotatable connection position between the rotating member 32 and the extending portion 311. The two ends of the elastic member 33 are respectively fixedly connected to the rotating member 32 and the extending portion 311, and has a tendency to drive the rotating member 32 to rotate towards the corresponding extending portion 311 to the limit position and stay. When the rotating member 32 rotates to the limit position under the drive of a plurality of elastic members 33, the rotating member 32 can contact and abut against the corresponding extending portion 311, and at this time, the width direction of the rotating member 32 is parallel to the width direction of the corresponding extending portion 311. In this embodiment, preferably, the elastic member 33 is a torsion spring; since the torsion spring is a common prior art, it will not be described in detail here, and only its installation position is shown in the drawings, and its structure is omitted.

[0039] The waterproof device 4 is installed on the side of the rotating plate facing away from the corresponding extending portion 311, and can guide rain and snow to move away from the wall body 1.

[0040] The waterproof device 4 includes a waterproof plate 41, a first waterproof member 42 and a second waterproof member 43.

[0041] The waterproof plate 41 is integrally in the shape of a rectangular plate and is detachably connected to the rotating plate. After the waterproof plate 41 is installed on the rotating member 32, the length direction and the width direction of the waterproof plate 41 are respectively parallel to the length direction and the width direction of the rotating member 32; at this time, after the waterproof plate 41 rotates to the limit position under the action of the elastic member 33 with the rotating member 32, the waterproof plate 41 will be in a position state inclined in the width direction, and the end of the waterproof plate 41 close to the protective layer 2 is the inclined upper end. In this embodiment, preferably, the waterproof plate 41 is detachably connected to the rotating plate by a plurality of screws and nuts; since the above-mentioned detachable connection method is a common prior art, it will not be described in detail here, and the relevant structures of the detachable connection are omitted in the drawings.

[0042] After the waterproof plate 41 is installed on the rotating member 32, the first waterproof member 42 is fixedly installed at one end of the waterproof plate 41 close to the protective layer 2. The first waterproof member 42 is integrally strip-shaped and distributed along the length direction of the waterproof plate 41; the first waterproof member 42 has elasticity and certain performance of resisting rain and snow erosion. After the waterproof plate 41 rotates with the rotating member 32 under the action of the elastic member 33, the first waterproof member 42 will contact and abut against the protective layer 2. At this time, the first waterproof member 42 is in a compressed state, and at this time, the first waterproof member 42 can reduce the probability that the rain and snow sliding down along the protective layer 2 passes through the gap between the waterproof plate 41 and the protective layer 2 and continues to slide down along the protective layer 2. In this embodiment, it is preferably that the first waterproof member 42 is made of rubber material.

[0043] After the waterproof plate 41 is installed on the rotating member 32, the second waterproof member 43 is installed above the extension portion 311 and located between the corresponding waterproof plate 41 and the protective layer 2. The second waterproof member 43 is also integrally strip-shaped and distributed along the length direction of the extension portion 311; the second waterproof member 43 also has elasticity and certain performance of resisting rain and snow erosion. The two ends of the second waterproof member 43 are respectively fixedly connected to the protective layer 2 and the rotating member 32 and contact and abut against the surface of the extension portion 311; after the rotating member 32 rotates under the action of the elastic member 33, at this time, the second waterproof member 43 is in a compressed state, and at this time, the second waterproof member 43 can reduce the probability that the rain and snow passing through the gap between the waterproof plate 41 and the protective layer 2 and continuing to slide down along the protective layer 2 contacts the wall body 1 through the gap between the extension portion 311 and the protective layer 2. In this embodiment, it is preferably that the second waterproof member 43 is also made of rubber material.

[0044] When the first waterproof member 42 is deformed due to rain and snow erosion, the waterproof plate 41 can rotate with the rotating member 32 under the action of the elastic member 33, so that the first waterproof member 42 keeps contacting and abutting against the protective layer 2 and keeps the first waterproof member 42 in a compressed state, so that the first waterproof member 42 can keep the effect of blocking rain and snow from passing through the gap between the protective layer 2 and the waterproof plate 41; at this time, the acting force on the second waterproof member 43 by the rotating member 32 increases, so that the degree of compression of the second waterproof member 43 is enhanced, so that the waterproof effect of the second waterproof member 43 above the extension portion 311 is improved.

[0045] When the rain and snow continue to slide down along the protective layer 2 after passing through the first waterproof member 42 and contact the second waterproof member 43, the rain and snow can leave from both ends in the length direction of the second waterproof member 43 along the surface of the top of the second waterproof member 43, which can reduce the probability that the rain and snow continue to contact the lower protective layer 2, and at the same time can reduce the probability that the rain and snow contacts the wall body 1 after passing through the gap between the extension portion 311 and the protective layer 2.

[0046] When the second waterproof member 43 is deformed by erosion by rain and snow, the rotating member 32 can rotate under the action of the elastic member 33, so that the second waterproof member 43 is further squeezed, so that the second waterproof member 43 is maintained above the extension part 311, and the gap between the extension part 311 and the protective layer 2 has a reliable waterproof effect; at this time, the force of the rotating member 32 on the first waterproof member 42 will also increase, so that the degree of squeezing of the first waterproof member 42 is enhanced, thereby improving the waterproof effect of the first waterproof member 42 between the protective layer 2 and the waterproof board 41.

[0047] Reference Figure 3 and Figure 4 Furthermore, in order to facilitate the elastic deformation of the first waterproof component 42 and the second waterproof component 43 after being squeezed, it is preferred that the first waterproof component 42 and the second waterproof component 43 have a plurality of deformation holes 44 inside.

[0048] When the first waterproof component 42 or the second waterproof component 43 is squeezed, the first waterproof component 42 or the second waterproof component 43 can undergo elastic deformation by changing the size of its deformation hole 44, so that the first waterproof component 42 can block rain and snow between the protective layer 2 and the waterproof board 41, and the second waterproof component 43 can block rain and snow below the corresponding first waterproof component 42.

[0049] Furthermore, in order to reduce the probability that rain and snow erode the first waterproof component 42 or the second waterproof component 43 and then enter the corresponding deformation hole 44 and stay there for a long time, causing the interior of the first waterproof component 42 or the second waterproof component 43 to be eroded by rain and snow for a long time, it is preferred that the two ends of the deformation hole 44 are respectively formed with openings at the two ends of the corresponding first waterproof component 42 or the second waterproof component 43 in the length direction.

[0050] At this time, rain and snow entering the deformation hole 44 can leave along the deformation hole 44 from the openings at both ends of the length direction of the corresponding first waterproof component 42 or the second waterproof component 43, effectively reducing the erosion effect of rain and snow on the first waterproof component 42 or the second waterproof component 43, thereby effectively extending the service life of the first waterproof component 42 or the second waterproof component 43.

[0051] One end of the waterproof board 41 away from the corresponding first waterproof member 42 is located on the side of the extension portion 311 away from the wall 1, and is located lower than the corresponding extension portion 311. At this time, rain and snow that directly falls on the waterproof board 41 and rain and snow that slide down along the protective layer 2 and are blocked by the corresponding first waterproof member 42 can slide down on the waterproof board 41 along the inclined direction of the waterproof board 41, so that the rain and snow can finally fall downward at a certain distance from the protective layer 2.

[0052] Furthermore, in order to reduce the impact of rain and snow directly falling on the waterproof plate 41 near its inclined lower end, so that the impact force of rain and snow on the waterproof plate 41 driving the rotating member 32 to rotate is greater than the influence of several elastic members 33 on the rotating member 32 driving the rotating member 32, resulting in the rotating member 32 rotating against the action of several elastic members 33, preferably, the rotation axis of the rotating member 32 is closer to the inclined lower end of the corresponding waterproof plate 41 relative to the corresponding waterproof plate 41, that is, the distance between the inclined lower end of the waterproof plate 41 and the rotation axis of the corresponding rotating member 32 is less than the distance between the inclined upper end of the waterproof plate 41 and the rotation axis of the corresponding rotating member 32.

[0053] At this time, under the action of external forces such as rain and snow impact, the waterproof plate 41 can maintain position stability relative to the protective layer 2, effectively achieving the waterproof effect.

[0054] Furthermore, in order to reduce the impact of rain and snow on the waterproof plate 41 when it falls on the position of the waterproof plate 41 near its inclined lower end, preferably, the inclined lower end of the waterproof plate 41 has a guiding portion 411.

[0055] The extending trajectory of the guiding portion 411 is an arc, and the arc opening of the guiding portion 411 is inclined downward toward the direction close to the protective layer 2. At this time, the rain and snow falling on the guiding portion 411 can quickly fall under the guidance of the guiding portion 411, and at the same time, it can reduce the influence of the impact force of rain and snow on the guiding portion 411 driving the corresponding rotating member 32 to rotate against the action of the elastic member 33.

[0056] Furthermore, in order to reduce the probability of people near the wall 1 being injured due to the inclined lower end of the waterproof plate 41 extending outward relative to the surface of the protective layer 2, preferably, the waterproof plate 41 has a protective structure 45 at the end of the guiding portion 411 that can reduce collision injuries. In this embodiment, preferably, the protective structure 45 is integrally in a cylindrical structure, and the axis of the protective structure 45 is parallel to the length direction of the waterproof plate 41.

[0057] Refer to Figure 1 and Figure 2 , the splash guard 5 is located at the bottom of the wall 1 and on the outside of the wall 1, the splash guard 5 is fixedly connected to the wall 1, is located below several preset devices 3, and the protective layer 2 covers the outer surface of the wall 1 above the splash guard 5.

[0058] The splash guard 5 is integrally in a cuboid structure, the width direction of the splash guard 5 is parallel to the extending direction of the extending portion 311, and the length direction is parallel to the length direction of the extending portion 311.

[0059] The splash guard 5 is provided with a groove 51 for collecting rain and snow. The groove 51 has an opening at the top of the splash guard 5, and the opening of the groove 51 is aligned with the inclined lower ends of a number of waterproof plates 41 in the vertical direction, that is, the rain and snow sliding off along the waterproof plates 41 can fall into the groove 51 under the action of their own gravity.

[0060] Further, preferably, the top of the splash guard 5 has a splash guard cover 52. The splash guard cover 52 is located at the top of the groove 51 and is located at a position of the groove 51 close to the wall 1. On the side of the splash guard cover 52 facing away from the wall 1, an entrance for rain and snow to enter the groove 51 is formed at the opening of the groove 51. The end face of the top of the splash guard cover 52 has a guiding surface 521, and the guiding surface 521 is inclined in the direction close to the entrance.

[0061] When the rain and snow leaving the waterproof plate 41 directly enter the groove 51 through the entrance, the splash guard 5 can prevent the rain and snow from splashing to the bottom of the protective layer 2 after falling into the groove 51; when the rain and snow leaving the waterproof plate 41 directly fall above the splash guard cover 52 (i.e., on the guiding surface 521), the guiding surface 521 can reduce the probability of the rain and snow splashing to the bottom of the protective layer 2, and at the same time can guide the rain and snow to move in the direction close to the entrance and enter the groove 51 through the entrance for collection.

[0062] Further, preferably, a number of drain holes 53 are provided at one end of the splash guard 5 away from the wall 1. The number of drain holes 53 is equally spaced along the length direction of the splash guard 5, and both ends of the drain holes 53 are communicated with the groove 51 and the space on the side of the splash guard 5 facing away from the wall 1 respectively.

[0063] After the rainwater and snow water collected in the groove 51 exceed a certain amount, they will be discharged through a number of drain holes 53 to the land on the side of the splash guard 5 facing away from the wall 1, reducing the impact of rainwater and snow water on the waterproof and anti-seepage performance of the wall 1.

[0064] A specific application of this embodiment is: In rainy and snowy weather, the rain and snow falling on the protective layer 2 will slide down along the protective layer 2 and move to the adjacent waterproof plate 41 under the block of the first waterproof member 42; when the rain and snow pass through the block of the first waterproof member 42, they will continue to slide down along the protective layer 2 to the second waterproof member 43 below, and after being blocked by the second waterproof member 43, the rain and snow will leave from both sides, effectively reducing the probability of the rain and snow contacting the protective layer 2; The rain and snow falling on the waterproof plate 41 will move along the waterproof plate 41 in the direction away from the protective layer 2. After the rain and snow leave along the guiding portion 411, they will fall into the groove 51 for collection. The splash guard 5 can effectively reduce the probability of the rain and snow splashing to the bottom of the protective layer 2 after landing, and at the same time can discharge the rainwater and snow water in a certain amount in the direction away from the wall 1, effectively reducing the impact of rain and snow on the waterproof and anti-seepage performance of the wall 1.
