TECHNICAL FIELD

[0001] The present application relates to the technical field of building structure, and particularly relates to a water dispersion outer wall integrated anti-cracking rainwater collecting structure. BACKGROUND

[0002] In building engineering, there are two core problems in the connection of water dispersion and outer wall and rainwater management: (1) structural cracking hazards: the traditional water dispersion and outer wall are independently constructed, and the joint has no collaborative stress design, so that the joint surface is prone to cracking when the building subsides, rainwater invades the foundation along the cracks, and the wall body is humidified, and the structural durability is reduced; the water dispersion and the drainage ditch are usually separately arranged, and the joint gap is easy to cause leakage and low drainage efficiency (such as wall body humidification, surface falling off, etc.); (2) functional fragmentation problem: due to the loose combination of water dispersion, outer wall and drainage ditch, it is difficult to form a unified rainwater management system, and the roof rainwater and surface runoff are discharged in disorder, which not only causes waste, but also increases the risk of waterlogging.

[0003] Therefore, it is necessary to design a water dispersion outer wall integrated anti-cracking rainwater collecting structure to solve the above problems. SUMMARY

[0004] The present application relates to the technical field of building structure, and particularly relates to a water dispersion outer wall integrated anti-cracking rainwater collecting structure.

[0005] In order to achieve the above-mentioned purpose of the application, the present application provides a water dispersion outer wall integrated anti-cracking rainwater collecting structure, which comprises: An outer wall connected with a foundation at the lower part; A water dispersion integrally poured with the outer wall to form a whole structure; A drainage ditch arranged below the water dispersion to receive the rainwater flowing down from the water dispersion, and the drainage ditch is adjacent to the side wall of the foundation on one side; Wherein, the bottom of the water dispersion is concave, comprising a first inclined section inclined upward away from the foundation and a second inclined section connected with the first inclined section and inclined downward away from the foundation, and the connecting point of the two inclined sections is located above the side of the drainage ditch close to the foundation, so that a limiting area with a vertical dimension first increasing and then decreasing away from the foundation is formed between the bottom surface of the water dispersion and the top of the side of the drainage ditch close to the foundation; and A water blocking part comprising a water blocking layer arranged on the bottom surface of the water dispersion and extending downward to cover at least the top surface of the side of the drainage ditch close to the foundation, and a water blocking material placed in a compressed state in the limiting area wrapped with the water blocking layer.

[0006] As a further improvement of the present application, a waterproof layer and a thermal insulation layer are further arranged on the outer side of the outer wall.

[0007] As a further improvement of the present application, an insulation layer is arranged between the foundation and the side of the drainage ditch close to the foundation.

[0008] As a further improvement of the present application, the width of the apron along the direction perpendicular to the outer wall is 1 / 3-1 / 2 of the width of the drainage ditch.

[0009] As a further improvement of the present application, a metal grate is arranged in the uncovered part of the drainage ditch.

[0010] As a further improvement of the present application, the vertical projection of the connecting point of the first inclined section and the second inclined section is located in the middle of the top of the side wall of the side of the drainage ditch close to the foundation.

[0011] As a further improvement of the present application, the slope of the second inclined section is greater than that of the first inclined section.

[0012] As a further improvement of the present application, the water-blocking material comprises any one of polystyrene foam, phenolic foam or polyurethane foam.

[0013] As a further improvement of the present application, the drainage ditch is further connected with a rain downpipe of the roof.

[0014] As a further improvement of the present application, a water storage tank is further arranged underground and connected with the drainage ditch, and a sprinkling device is arranged on the water storage tank and in communication with the water storage tank.

[0015] The present application has the following advantages: 1. The present application forms an integrated structure by rigidly connecting the apron with the outer wall, which can eliminate the gap between the apron and the outer wall caused by independent construction of the apron and the outer wall, offset the settlement stress, and block the cracking path between the apron and the outer wall.

[0016] 2. The present application can utilize "dredging" instead of "blocking" by arranging the drainage ditch below the water disperser, with one side adjacent to the outside of the foundation, to collect rainwater into the drainage ditch and realize the orderly discharge of rainwater. At the same time, by recessing the bottom surface of the water disperser, on the one hand, the first inclined section can be used for water diversion, to a certain extent, to avoid water flow to the limiting area, on the other hand, a limiting area with a vertical dimension that first increases and then decreases away from the foundation direction is formed between the bottom surface of the water disperser and the top of one side of the drainage ditch. Further, by installing the water-blocking material in a compressed state in the limiting area, the top of the water-blocking material and the bottom surface of the water disperser and the top of one side of the drainage ditch are in good abutting state, and the compression degree of the water-blocking material gradually increases along the direction from the middle to both sides of the water-blocking material, so that the connection between both sides of the water-blocking material and the limiting area is the most tight, which can not only make the water-blocking material have good water-blocking ability on the water surface, but also utilize the size characteristics of the limiting area to clamp the water-blocking material in the limiting area, to a certain extent, to improve the fixing effect of the water-blocking material, and also utilize the water-blocking material to self-seal the limiting area, so that the water-blocking material serves as the first waterproof layer, and further cooperates with the water-blocking layer as the second waterproof layer to realize effective water-blocking and avoid rainwater leakage to the foundation, thereby improving the durability of the building.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be described in detail below with reference to the drawings and specific embodiments.

[0021] Here, it also needs to be explained that, in order not to obscure the present application due to unnecessary details, only the structures and / or processing steps closely related to the scheme of the present application are shown in the drawings, and other details not closely related to the present application are omitted.

[0022] It is also to be noted that the terms "comprising", "including", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0023] As shown in Figure 1 and Figure 2 The present application provides a water dispersion outer wall integrated anti-cracking rainwater collection structure, comprising: An outer wall 11 connected with a foundation 12 at the lower part; A water dispersion 20 integrally poured with the outer wall 11 to form an integrated structure; A drainage ditch 30 arranged below the water dispersion 20 to receive the rainwater flowing down from the water dispersion 20, and the drainage ditch 30 is adjacent to the side wall of the foundation 12 on one side; Wherein, the bottom of the water dispersion 20 is concave, including a first inclined section 21 inclined upward away from the foundation 12 and a second inclined section 22 connected with the first inclined section 21 and inclined downward away from the foundation 12, and the connection point of the two inclined sections is above the side of the drainage ditch 30 close to the foundation 12, so that a limiting area 23 with a vertical dimension first increasing and then decreasing away from the foundation 12 is formed between the bottom surface of the water dispersion 20 and the top of the side of the drainage ditch 30 close to the foundation 12; and A water blocking part including a water blocking layer 41 arranged on the bottom surface of the water dispersion 20 and extending downward to cover at least the top surface of the side of the drainage ditch 30 close to the foundation 12, and a water blocking material 42 placed in a compressed state in the limiting area 23 wrapped with the water blocking layer 41.

[0024] For example, the inner side of the outer wall 11 is connected with the indoor floor 72, and the outer side of the outer wall 11 is further provided with a waterproof layer 111 and a thermal insulation layer 112 in sequence, and the waterproof layer 111 is tightly attached to the outer wall 111 of the outer wall 11 and extends to the top surface of the water dispersion 20 layer, wherein the width of the waterproof layer 111 on the top surface of the water dispersion 20 layer is greater than or equal to the width of the thermal insulation layer 112.

[0025] The waterproof layer 111 is made of SBS waterproof coiled material with a thickness of 3mm.

[0026] For example, the water dispersion 20 and the outer wall 11 are integrally poured with integrated formwork, so that the water dispersion 20 and the outer wall 11 form an integrated structure to strengthen the combined stress of the water dispersion 20 and the outer wall 11, offset the stress generated by building settlement, avoid cracks at the junction of the water dispersion 20 and the outer wall 11 due to stress separation, and block the erosion path of rainwater from the root cause. Wherein, the slope of the water dispersion 20 is 3%.

[0027] Exemplary, the heat preservation layer 112 is also arranged between the foundation 12 and the left side of the drainage ditch 30. The material of the heat preservation layer 112 mentioned in the present application is all polystyrene board.

[0028] Specifically, the limiting area 23 also serves as a expansion joint between the apron 20 and the drainage ditch 30, and adapts to the settlement of the foundation 12.

[0029] Specifically, the vertical projection of the connecting point of the first inclined section 21 and the second inclined section 22 is located at the middle position of the top surface of the left side wall of the drainage ditch 30, and the slope of the second inclined section 22 is greater than that of the first inclined section 21, so that the vertical dimension of the limiting area 23 close to the foundation 12 side is less than that of the limiting area 23 away from the foundation 12 side.

[0030] By concave setting of the bottom surface of the apron 20, on the one hand, water flow can be guided by the first inclined section 21, to a certain extent, to avoid water flow to the limiting area 23, to a certain extent, to play a certain degree of water resistance, on the other hand, the water resistance material 42 can be installed in a compressed state in the limiting area 23, so that the top of the water resistance material 42 and the bottom surface of the apron 20 and the bottom of the water resistance material 42 and the top of one side of the drainage ditch 30 are in good abutting state, and along the direction from the middle of the water resistance material 42 to its two sides, the compression degree of the water resistance material 42 gradually increases, so that the connection tightness of the two sides of the water resistance material 42 and the limiting area 23 is the largest, which can not only make the water resistance material 42 have good water resistance on the water surface, but also use the size characteristics of the limiting area 23 to clamp the water resistance material 42 in the limiting area 23, to a certain extent, to improve the fixing effect of the water resistance material 42, and also use the water resistance material 42 to self-seal the limiting area 23, so that the water resistance material 42 serves as the first waterproof layer, further cooperates with the water resistance layer 41 as the second waterproof layer, realizes effective water resistance, and avoids rainwater from leaking to the foundation 12.

[0031] Among them, by making the slope of the second inclined section 22 greater than that of the first inclined section 21, the clamping effect of the left side of the water resistance material 42 is better than that of the right side, that is, when the water resistance material 42 has a tendency to move to the left under the action of water flow impact or water pressure, the characteristics that the vertical dimension of the left side of the limiting area 23 is smaller than that of the right side and gradually decreases along the left direction can provide a force to prevent the water resistance material 42 from moving to a certain extent, and when the water resistance material 42 moves to the left under the action of external force, the water resistance material 42 will be further compressed, so that the connection tightness between the left side of the water resistance material 42 and the bottom surface of the apron 20 and the top surface of the left side of the drainage ditch 30 is further enhanced, that is, the water resistance material 42 is self-sealed to the limiting area 23, so that the water resistance material 42 can still maintain good water resistance effect.

[0032] Exemplarily, the top surface of the water-blocking material 42 and the bottom surface of the water disperser 20 are fixed by an adhesive such as an epoxy resin adhesive, and the water-blocking material 42 and the top surface of the left side of the drainage ditch 30 are fixed by the adhesive. In actual use, the adhesive mainly plays a surface fixing role. When the water-blocking material 42 is stressed to cause the water-blocking material 42 to separate from the body of the water-blocking material 42 at the bonding site, so that the adhesive cannot fix the water-blocking material 42, the presence of the limiting area 23 can further utilize the compressed state of the water-blocking material 42 to make the water-blocking material 42 still abut the water disperser 20 and the drainage ditch 30 by the resilience, so as to play a water-blocking role and avoid rainwater from leaking between the foundation 12 and the side wall of the drainage ditch 30, thereby greatly improving the durability of the building.

[0033] Specifically, the water-blocking material 42 includes any one of polystyrene foam plastic, phenolic foam plastic or polyurethane foam plastic. In this example, the water-blocking material 42 is polystyrene foam plastic. The water-blocking layer 41 is made of SBS waterproof coiled material with a thickness of 3 mm. In this example, the water-blocking layer 41 covers the bottom surface of the water disperser 20 and extends downward to cover the top surface of the left side of the drainage ditch 30 and the inner wall of the left side of the drainage ditch 30.

[0034] Specifically, in the direction perpendicular to the outer wall 11, the width of the water disperser 20 is 1 / 3-1 / 2 of the width of the drainage ditch 30, so that rainwater under different rainfall can flow into the drainage ditch 30 along the water disperser 20 for collection. In this example, the width of the water disperser 20 is 1 / 2 of the width of the drainage ditch 30.

[0035] The uncovered part of the drainage ditch 30 is provided with a metal grate 31. Exemplarily, the left side of the metal grate 31 is connected with the water disperser 20 and the right side is connected with the outdoor ground 71, so as to realize full coverage of the drainage ditch 30 by the water disperser 20 and the metal grate 31, protect the top of the drainage ditch 30 and guide the flow of rainwater, so that the rainwater flows to the metal grate 31 through the water disperser 20, and then flows to the drainage ditch 30. The metal grate 31 is provided with a pebble interception layer 32 composed of a plurality of pebbles above the metal grate 31, so as to intercept dry branches, leaves and large particles by the pebble interception layer 32, and coarsely filter the rainwater.

[0036] Exemplarily, the drainage ditch 30 is also connected with a rainwater downpipe 50 of the roof, as shown in Figure 1 The rainwater downpipe 50 extends to the underground and communicates with the drainage ditch 30, so as to directly drain the roof rainwater into the drainage ditch 30 through the rainwater downpipe 50.

[0037] Exemplarily, the bottom right of the drainage ditch 30 is further connected with the underground water storage tank 60 through the collecting pipe 61, and the sprinkling irrigation device 62 extending to the ground is arranged on the water storage tank 60 and in communication with the water storage tank 60, so that after the rainwater is collected in the drainage ditch 30, part of the rainwater flows to the water storage tank 60 through the collecting pipe 61 for storage, and when water supply is needed for the green area, the rainwater in the water storage tank 60 is used to supply water for the green area by the sprinkling irrigation device 62, so as to realize the resource utilization of rainwater.

[0038] The bottom of the drainage ditch 30 is paved with the graded sand filter layer 33 to preliminarily purify the rainwater such as to intercept the silt and suspended matter, and the top surface of the graded sand filter layer 33 is paved to the water permeable geotextile 34, the water outlet of the rainwater pipe 50 is located above the graded sand filter layer 33, and the inlet height of the rainwater pipe 50 is lower than the top surface of the graded sand filter layer 33, so as to filter the rainwater by the graded sand filter layer 33 and the water permeable geotextile 34, and then the filtered rainwater is discharged into the water storage tank 60 through the collecting pipe 61.

[0039] Exemplarily, the thickness of the graded sand filter layer 33 is 100 mm, a 5 mm filter screen is arranged at the inlet of the collecting pipe 61, and the slope of the collecting pipe 61 is 2%, so that the rainwater automatically flows to the water storage tank 60 through the drainage ditch 30.

[0040] The sprinkling irrigation device 62 is a conventional sprinkling irrigation device 62, which will not be described herein.

[0041] The combination of the water disperser 20 and the drainage ditch 30 can quickly disperse and collect rainwater, so that the rainwater enters the water storage tank 60 through the collecting pipe 61, and then the collected rainwater is used for green irrigation by the sprinkling irrigation device 62.

[0042] The water disperser 20 outer wall 11 integrated anti-cracking rainwater collection structure integrates water blocking, filtering, storage and sprinkling, converts the waste rainwater into water for greening, reduces the dependence on municipal water supply, fits the concept of sponge city and energy saving, and simultaneously avoids the cracking of the connection between the water disperser 20 and the outer wall 11 and the leakage of rainwater to the foundation 12 by the integrated design of the water disperser 20 and the outer wall 11, the replacement of “blocking” by “dispersing” for part of the drainage ditch 30, and the two-step water blocking design of the water blocking material 42 and the water blocking layer 41, thereby ensuring the long-term stability of the structure.

[0043] The above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application, and although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application.
