Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a construction method and structure for preventing water seepage and sinking at the exterior walls of buildings. Background Technology

[0002] A drainage slope is an outdoor section of ground that slopes perpendicularly to the base of an exterior wall. It is used to drain rainwater and protect the foundation from erosion. Drainage slopes are typically made of brick or concrete. The purpose of a drainage slope is to allow water to drain quickly from the ground near the base of the building's exterior walls, prevent dripping from the eaves from eroding the soil around the walls, reduce the possibility of water damage to the walls and foundation, protect the walls and foundation, and extend the building's lifespan.

[0003] Currently, before construction, the ground around the building walls is usually compacted. The drainage slope is then constructed on the compacted ground. However, after the drainage slope is constructed, the edges lack protective measures. As rainwater drips down the slope over a long period of time, grooves easily form where the rainwater drips. With prolonged use, the soil under the drainage slope tends to flow into the grooves, causing the bottom of the drainage slope to become hollow, making the drainage slope prone to subsidence or cracking.

[0004] Therefore, we propose a construction method and structure for preventing water seepage and sinking at the exterior walls of buildings, in order to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to solve the aforementioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A construction structure for preventing water seepage and subsidence at the exterior wall of a building includes a building wall. The exterior wall surface of the building wall is provided with several first baffles placed on the ground. A fixed plate is provided at the external corner of the building wall, also placed on the ground. A second baffle is installed on the multiple first baffles located on the same side. The opposite ends of two second baffles are connected to the fixed plate. Several foundation pits are formed between the first baffles and the fixed plate, and between adjacent first baffles, the building wall, and the second baffles, respectively. A solidified drainage slope is poured into the interior of the foundation pits, and the drainage slope slopes downwards on the side away from the building wall.

[0007] Furthermore, a reinforcing plate is installed on several of the first baffles located on the same side, and the reinforcing plate is located between the second baffle and the building wall and is arranged parallel to each other.

[0008] Furthermore: the second baffle is connected to the plurality of first baffles by welding, and the reinforcing plate is connected to the plurality of first baffles by welding.

[0009] Furthermore, fixing ribs are welded to the top of several of the first baffles and the reinforcing plates, and the fixing ribs are used to reinforce the first baffles and the reinforcing plates.

[0010] Furthermore: the top of the first baffle is provided with a first mounting groove, and the bottom of the reinforcing plate is provided with a second mounting groove; and several second mounting grooves at the bottom of the reinforcing plate are respectively inserted and adapted to several first mounting grooves at the top of the first baffle.

[0011] Furthermore: one end of the first baffle is fixed with an installation plate pre-embedded in the building wall, and several reinforcing ribs are fixed on both sides of the installation plate.

[0012] Furthermore: a number of threaded posts are fixed at the end of the first baffle away from the building wall, and the second baffle is provided with through holes that are compatible with the threaded posts, and locking nuts are installed on the threaded posts through the through holes.

[0013] Furthermore: one end of the fixing plate is fixed with a first fixing member in an inclined manner, and a first rib is fixed at the angle between the first fixing member and the fixing plate. The first fixing member is threadedly connected to the end of the second baffle by a number of fixing bolts.

[0014] Furthermore: a second fastener is symmetrically fixed at one end of the fixing plate near the building wall in a fixed inclined manner, and a second rib is fixed between the second fastener and the fixing plate. The second fastener is fixedly connected to the corner of the building wall by expansion bolts.

[0015] A construction method for preventing the subsidence of the waterproofing slab at the exterior wall of a building: S1: The mounting plate at one end of multiple first baffles is pre-embedded in the building wall; When the building wall is being constructed, the mounting plate at one end of the first baffle is embedded longitudinally inside the building wall; the reinforcing bars on both sides of the mounting plate are embedded transversely inside the building wall; after the building wall is completely solidified, they serve to fix the first baffle. S2: Fix the second baffle; A second baffle is placed at the end of multiple first baffles away from the building wall, so that one end of several first baffles is attached to the second baffle and fixed together; so that several foundation pits are formed between adjacent first baffles, building walls and second baffles, and between first baffles, fixing plates, building walls and second baffles. S3: Construct the same reinforcing plate on several first baffles: The same reinforcing plate is placed on several first baffles, such that several second mounting slots at the bottom of the reinforcing plate are inserted and adapted to the first mounting slots at the top of the first baffles, so as to support the several first baffles. S4: Pour concrete inside the foundation pit; Concrete is poured and vibrated inside the foundation pit. After the concrete has completely solidified, the top surface of the concrete is sloped to form a drainage slope.

[0016] The beneficial effects of this invention are: This invention provides several first baffles and second baffles at the outer edge of the building wall. On one hand, the building wall, the second baffles, and the several first baffles can form several foundation pits, which can protect the soil under the apron and prevent soil loss around the apron. This effectively prevents the apron from cracking or sinking. On the other hand, the cooperation of the first and second baffles supports the apron slope, so even if there is a hollow area under the apron, the apron will not sink. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0020] A construction structure for preventing water seepage and settlement at the exterior wall of a building includes a building wall 1 (the building wall 1 can be a shear wall or a brick wall; users can choose flexibly according to their needs without restriction). It should be noted that: a horizontal concrete beam is installed at the water seepage point of the building wall 1 to fix the building wall 1; several parallel first baffles 3 are installed on the exterior wall surface of the building wall 1, and the first baffles 3 are in contact with the ground 2; the first baffles 3 provide a foundation for the subsequent foundation pit; the multiple first baffles 3 are located away from the building... One end of the building wall 1 is equipped with the same second baffle 5, and the second baffle 5 is set parallel to the outer wall surface of the building wall 1. The second baffle 5 serves two purposes: firstly, it fixes one end of several first baffles 3, preventing the end of the first baffle 3 away from the building wall 1 from swaying or loosening, thereby improving the stability of the construction structure; secondly, the building wall 1, the adjacent first baffles 3 and the second baffle 5 can form several "rectangular" foundation pits (not marked in the figure), reducing the loss of concrete when pouring it into the foundation pits.

[0021] The same reinforcing plate 10 is installed on multiple first baffles 3 located on the same side. The reinforcing plate 10 is located between the building wall 1 and the second baffle 5 and is parallel to the second baffle 5. By setting the reinforcing plate 10, on the one hand, it plays a role in supporting the middle part of the multiple first baffles 3, further improving the stability of the first baffles 3; on the other hand, the multiple reinforcing plates 10 can divide the foundation pit trench, and the reinforcing plate 10 can block the concrete in the foundation pit trench in batches, preventing the second baffle 5 from tilting due to excessive extrusion pressure from the concrete.

[0022] Fixing plates 4 are installed at both the internal and external corners of the building wall 1, and the bottom of the fixing plates 4 is also attached to the ground 2. The opposite ends of the two second baffles 5 are connected to the tail end of the fixing plates 4. The fixing plates 4 facilitate the pouring of the drainage slope 9 at the external corners of the building wall 1.

[0023] It should be noted that the first baffle 3, the fixing plate 4, the second baffle 5, and the reinforcing plate 10 mentioned above can be constructed in two ways. For details, please refer to Embodiment 1 and Embodiment 2 below. During on-site construction, users can make flexible choices according to their construction needs. Example

[0024] The second baffle 5 is connected to several first baffles 3 by welding, and the reinforcing plate 10 is also connected to the first baffle 3 by welding. The advantages of this design are: the first baffle 3, the second baffle 5 and the reinforcing plate 10 can form an integral frame structure, which reduces the assembly process during on-site construction and saves time and effort; in addition, the length of the frame structure can be cut according to the length of the building wall 1 during on-site construction, which has strong adaptability and flexibility.

[0025] Several first baffles 3 and the top of the reinforcing plate 10 are welded with fixing ribs 11, which are used to reinforce the top of the first baffles 3 and the reinforcing plate 10 to prevent the frame structure from deforming during use and have strong stability.

[0026] Before constructing the drainage slope 9, the frame and reinforcement plate 10 need to be constructed.

[0027] It should be noted that before the frame is erected, the template needs to be cut according to the length of the building wall 1 so that the frame is compatible with the length of the building wall 1.

[0028] During construction: First, the reinforcing plate 10 is fixed to the external corner of the building wall 1 with expansion bolts; second, the cut frame is placed on the outer wall of the building wall 1 and fits together, with the two adjacent frames abutting against the fixing plate 4, thus completing the construction of the drainage slope skeleton.

[0029] After the construction is completed, concrete is poured into the foundation pit and vibrated with a vibrator. When the concrete completely covers the fixing bar 11, the pouring is completed. Next, the top of the concrete is sloped. Finally, a drainage slope 9 is formed.

[0030] After the drainage slope 9 has completely solidified, sealant is filled into the gap between the drainage slope 9 and the building wall 1 (sealant is a known prior art and will not be described in detail in this application), thereby improving the sealing performance and reducing the occurrence of water seepage later. Example

[0031] A mounting plate 12 is fixed to one side of the first baffle 3. During the construction of the building wall 1, the mounting plate 12 at one end of the first baffle 3 is installed vertically inside the building wall 1. Several reinforcing ribs 13 are fixed on both sides of the mounting plate 12, and these reinforcing ribs 13 are embedded horizontally inside the building wall 1. After the building wall 1 is completely solidified, they serve to fix the mounting plate 12 and the reinforcing ribs 13, making the first baffle 3 and the building wall 1 integrally formed. The advantages of this design are: the first baffle 3 and the building wall 1 have good connection strength; after the concrete is laid and solidified, the solidified concrete forms an integral structure with the building wall 1 through the several first baffles 3. Compared with the traditional method of directly laying concrete on the ground 2, it has good stability, and the concrete after solidification is not prone to sinking or cracking, and has strong stability.

[0032] In detail: Each first baffle 3 has several threaded posts 14 fixed at the end away from the building wall 1; and the second baffle 5 has several through holes 15 corresponding to the threaded posts 14, and one end of the threaded post 14 is threaded through the through hole 15 and a locking nut (not shown in the figure) is installed. Through the cooperation of the threaded post 14, the through hole 15 and the locking nut, the second baffle 5 is fastened to prevent the second baffle 5 from loosening during use.

[0033] The first fixing member 601 is fixed at an angle to the end of the fixing plate 4 away from the building wall 1, and a first rib 602 is fixed at the angle between the first fixing member 601 and the fixing plate 4. The first rib 602 is used to reinforce the first fixing member 601 and prevent deformation during use. Each first fixing member 601 is threaded to the end of the second baffle 5 by several fixing bolts, thereby fastening the second baffle 5 and preventing the end of the second baffle 5 from loosening. It should be noted that the building wall 1, the first baffle 3, the fixing plate 4 and the second baffle 5 can also form a foundation pit in the shape of a "right trapezoid", and the inside of the foundation pit is also filled with concrete.

[0034] In detail: A second fastener 16 is symmetrically fixed at an angle to one end of the fixing plate 4 near the building wall 1. Several second ribs 17 are provided at the connection between the second fastener 16 and the fixing plate 4. These second ribs 17 reinforce the second fastener 16, preventing deformation during use. Each second fastener 16 is fixed to the wall surface of the building wall 1 by several expansion bolts, further reinforcing the fixing plate 4 and preventing loosening or swaying during use, thus improving the stability of the construction structure. In detail: Each first baffle 3 has a downwardly extending first mounting groove 301 at its top, and several first mounting grooves 301 on the same side are arranged collinearly; the bottom of the reinforcing plate 10 has several second mounting grooves 1001 equidistantly provided, and the several second mounting grooves 1001 at the bottom of the reinforcing plate 10 are respectively inserted into the first mounting grooves 301 at the top of several first baffles 3. Through the cooperation of the second mounting grooves 1001 and the first mounting grooves 301, the first baffles 3 and the reinforcing plate 10 can support each other and prevent the middle part of the first baffle 3 from swaying. It should be noted that: the two ends of the reinforcing plate 10 are respectively provided with downwardly extending notches 1002. One notch 1002 is inserted and adapted to the first mounting groove 301 located at the edge, and the other notch 1002 is inserted and adapted to the "V" shaped groove 401 opened on the top of the fixing plate 4, so that the ends of the two fixing plates 4 abut against each other to prevent shaking. In addition, this installation method is simple to operate and provides convenience for workers.

[0035] If this anti-sinking construction structure is used for construction, the following steps should be followed in conjunction with Example 2: S1: The mounting plate 12 at one end of the multiple first baffles 3 is pre-embedded in the building wall 1; The building wall 1 is erected during construction; the mounting plate 12 at one end of the first baffle 3 is embedded longitudinally inside the building wall 1; the reinforcing bars 13 on both sides of the mounting plate 12 are embedded transversely inside the building wall 1; after the building wall 1 is completely solidified, it serves to fix the first baffle 3.

[0036] S2: Fix the second baffle 5; A second baffle 5 is placed at the end of multiple first baffles 3 away from the building wall 1. Multiple threaded posts 14 at the end of each first baffle 3 away from the building wall 1 are threaded through holes 15 and locked with nuts to fix the second baffle 5 and prevent it from loosening during use. After the second baffle 5 is completely fixed at one end of several first baffles 3, several foundation pits are formed between the building wall 1, the first baffles 3, the fixing plate 4 and the second baffle 5. The foundation pits are used to fill concrete.

[0037] S3: Construct the same reinforcing plate 10 on several first baffles 3: The same reinforcing plate 10 is placed on several first baffles 3, such that several second mounting grooves 1001 at the bottom of the reinforcing plate 10 are respectively inserted and adapted to the first mounting grooves 301 at the top of several first baffles 3, so as to support the central part of several first baffles 3, so that the first baffles 3 and the reinforcing plate 10 can support each other, prevent swaying, and improve the stability of the structure.

[0038] S4: Pour a drainage slope 9 inside the foundation pit trench; Concrete is poured inside the foundation pit. After the concrete is poured, it is vibrated with a vibrator to ensure that the drainage slope 9 is filled densely. After the drainage slope 9 is vibrated, the top surface of the concrete is sloped. The inclination angle of the drainage slope 9 is 3-5 degrees to ensure that rainwater can flow and reduce water accumulation. After the concrete has completely solidified, the drainage slope 9 is formed. Next, sealant can be filled at the connection between the drainage slope 9 and the building wall 1 to seal and reduce water seepage.
