Basement waterproofing method and waterproofing structure

Abstract

This solution discloses a basement waterproofing method. A control module controls a motor to pull metal cables, driving the rise and fall of a flexible waterproof fabric layer. The flexible waterproof fabric is compressed and sealed by a compression structure within the columns that secure the fabric. Metal crossbars are evenly spaced across the flexible waterproof fabric, and the crossbars are limited by the openings in the columns. The control module collects signals from float switches within the columns to control the rise and fall of the motor. This solution, based on the rise and fall of the flexible waterproof fabric, achieves garage waterproofing by compressing the flexible waterproof fabric within the columns on both sides. Furthermore, the float switches within the columns, in conjunction with control by the main control module, automatically raise the waterproof fabric in the event of excessive water accumulation.

[0002] Underground buildings, especially garages, are necessary infrastructure to meet the current increase in vehicles and solve parking problems. However, in rainy weather, when the rainfall is heavy and the drainage system is not smooth and the drainage problem cannot be solved, underground garages are likely to be flooded with rainwater, causing property losses and also posing safety risks.

[0003] At present, most of the garages in domestic residential areas, supermarkets and other comprehensive public places are sealed with sandbags to prevent flooding. This method requires the waterproof device to take up a lot of space and has a large weight. In case of emergency, multiple people must work together to operate it, which increases the difficulty of use.

[0004] There is also a garage waterproofing device disclosed in CN202120753999.2, which adopts a rigid water retaining plate design. This solution still requires manual water retaining assembly. If an automatically lifting garage waterproofing structure can be realized, it can achieve a rapid response to garage waterproofing in rainy weather. Summary of the Invention

[0047] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0048] First, this embodiment is directed to a type of waterproof structure for underground buildings, mainly a waterproof structure for underground garages.

[0049] like Figure 1-11As shown, a waterproof structure based on a flexible waterproof cloth includes the following important structural components:

[0050] The waterproof lifting structure 100 fixes the flexible waterproof cloth 101 and lifts it up and down.

[0051] A set of columns 1, hollow inside, arranged opposite to each other, used to set up a waterproof lifting structure;

[0052] The base groove 5 is provided with the column 1, and the bottom side of the column 1 is sealed with the flexible waterproof cloth 101;

[0053] Adjusting the compression structure to laterally compress and seal the flexible waterproof cloth 101;

[0054] The motor 200 pulls the waterproof lifting structure 100 on the upper side of the column 1;

[0055] The pulley and the motor form the four corners of a quadrilateral, controlling the synchronous lifting of the two ends of the waterproof lifting structure 100

[0056] The column 1 is a rectangular parallelepiped structure with an opening slot 2 formed thereon. The inner side of the column 1 is hollow and the top side is a fixed platform for placing the motor 200. The motor is used to pull the metal cable. Figure 5 As shown, the fixed platform has a through hole starting from the center axis of the column for metal cables to pass through.

[0057] This part of the design shows that the power of the waterproof lifting structure comes from the motor 200, and the motor 200 is a common motor purchased on the market, so no further details are given.

[0058] The columns are arranged on both sides opposite to each other, specifically the opening grooves 2 are arranged opposite to each other, so that the waterproof lifting structure can be slidably limited in the columns.

[0059] Specifically, in this embodiment, Figure 1 As shown, the waterproof lifting structure 100 is a metal lifting component with a waterproof cloth fixed on the lower side. The waterproof cloth is inside the column and is compressed by the adjustable compression structure provided in the column 1 to form lateral waterproofing inside the column.

[0060] Continue to refer to the attached Figure 8 , the waterproof lifting structure 100 includes:

[0061] The clip end 102 clamps the flexible waterproof cloth 101; the flexible waterproof cloth is PVC waterproof cloth, which is a common commercial material and is easy to obtain. It can be set as a single layer or a multi-layer stacked layer. When it is set in multiple layers, each layer of waterproof cloth is glued together.

[0062] When the flexible waterproof cloth 101 is fixed to the clip end, refer to the attached Figure 9The clip end includes L-shaped clips 102a, 102b, which are bolted and spliced ​​at equal intervals to clamp the flexible waterproof cloth 101. Specifically, the clamping locking bolt passes through the clip end to lock the two L-shaped clips. At the same time, the clamping locking screw also passes through the flexible waterproof cloth 101, that is, the waterproof cloth is provided with a through hole for the bolt to pass through.

[0063] In this waterproof structure, the joint surface of the L-shaped clips 102a, 102b is provided with a waterproof sealing belt 102c that is offset up and down. This design is a design to ensure the reliability of clamping. The sealing belt 102c can increase the friction during clamping. Since the flexible waterproof cloth itself is a sheet material, and the L-shaped clip is a longer surface extrusion fixing method, as a reliable clamping design, it can reduce the processing accuracy of the L-shaped clip and reduce the processing difficulty.

[0064] As an alternative reliability implementation solution in this article, the sealing tape 102c may not be involved and can be achieved by setting metal gaskets on both sides of the flexible waterproof cloth 101 when the clamping locking screw is tightened.

[0065] In the design of the waterproof structure, the design spacing of the clamping locking screws is 6-10cm, which can effectively ensure the reliability of the top connection.

[0066] Continue to refer to the attached Figure 9 , the waterproof lifting structure 100 further includes:

[0067] The rolling wheels 103 are fixed on both sides of the clip end 102 and roll up and down in the column 1;

[0068] The hanging rings 104 are located on both sides of the clip end 102 and are connected to the metal cables 300 driven by the motor.

[0069] The rolling wheel 103 is a rubber wheel, which is fixed to the end of the clip and is limited by the inner wall of the column 1. Specifically, an extended rod fixed to the end of the clip passes through the open slot 2 on the column 1, and the rubber wheel is just limited by the inner wall in the column 1, so that the rubber wheel can roll up and down in the column 1, assisting the movement of the waterproof lifting structure and improving smoothness.

[0070] In this design, the rubber wheel and the adjusting and pressing structure are located on different longitudinal axes and do not affect each other. Preferably, the rubber wheel is closer to the inner side (away from the side of the opening groove).

[0071] The lifting ring 104 is designed to connect the metal cable 300 to ensure that the waterproof lifting structure can be moved.

[0072] Continue to refer to the attached Figure 3-5 , the first pulley 6 is arranged on the bottom side of the column 1, located at the central axis, and transmits horizontally; or,

[0073] The first pulley is arranged in the base groove 5, covered by the column 1, located at the center axis position inside the column 1, and transmits horizontally.

[0074] Furthermore, combined with Figure 6 ;

[0075] The second pulley 7 is arranged on the top side of the column 1, located at the center axis, and transmits the power longitudinally; and

[0076] It is provided on one side of the opposite column 1 in the base groove 5, specifically on a different side from the motor.

[0077] That is, a motor is provided on the top of one of the two opposing columns, and a second pulley is provided on the top of the other side, while the first pulley at the bottom is arranged in the base groove 5 or in the column 1 to realize the transmission of the lifting structure.

[0078] In the design of the first pulley 6, it and the adjusting and pressing structure are located on different longitudinal axes, and the two do not affect each other. Preferably, the first pulley 6 is closer to the outside (close to the side of the opening groove).

[0079] In the transmission mechanism of the waterproof lifting structure, combined with the attached Figure 7 The motor 200 drives one end, and the end of the lifting member on the motor side continues to pass through the metal cable through the first pulley, and the second pulley hangs the other side of the metal lifting member. When the motor is running, the two ends of the lifting member are lifted and lowered at the same time, forming the up and down lifting of the waterproof cloth.

[0080] It is worth noting that the metal cable 300 is divided into two sections, one section is the motor-driven clip end hanging point (left side), and the other section is the clip end on one side (left side) connected to the hanging ring of the clip end on the other side (right side) through the first pulley and the second pulley. The length of this section of metal cable ensures that the clip end is horizontal in the column 1, thereby realizing a motor-controlled lifting and lowering of the clip end.

[0081] After the waterproof lifting structure is raised and lowered, the pressing structure is adjusted to press and seal.

[0082] Continue to refer to the attached Figure 2 、 5 and 6; the adjusting and pressing structure includes:

[0083] The fixed end 41 is fixed to the column 1, and can be fixed to the inside of the column away from the opening side, or the fixed end can be directly inside the column 1. In this embodiment, it is independently set and fixed inside the column, which can reduce the stroke of the clamping end.

[0084] The pressing end 42 is connected to the side wall of the column 1 through a pressing clamp 43; the pressing clamp 43 pushes the pressing end 42 to overlap with the fixed end 41. Due to the setting of the pressing clamp 43, the pressing end has horizontal freedom. In this embodiment, the pressing end and the fixed end are matching metal strips, and a sealing strip 411 is provided on the fixed end from top to bottom, so that when the pressing end presses the waterproof cloth, the sealing strip can have the effect of interference sealing, thereby improving the waterproof ability.

[0085] Continue to refer to the attached Figure 5 Or 6, the pressing clamps 43 are arranged at equal intervals on the side wall of the column 1. This arrangement can solve the problem of insufficient single-point pressing when the pressing end is a long metal strip, and further ensure the sealing effect.

[0086] The clamping clamp 43 is a manual clamp. Specifically, the clamp can be made of hardware of the Bogong brand, which has various clamps such as push-pull type. In application, it can be fixed by unconnected metal parts or directly fixed to the side wall. As a technical means fully known to those skilled in the art, no further details are given here.

[0087] As attached Figure 8 and 10 As shown, the metal cross bars 400 are arranged at equal intervals on the flexible waterproof cloth 101, and,

[0088] The two side ends are located inside the column 1 and are limited by the open slots 2 provided opposite to the column 1 .

[0089] The metal cross bar 400 is connected to the flexible waterproof cloth 101 by gluing. If it is a single-layer waterproof cloth, it is glued through an additional waterproof cloth layer. If it is a multi-layer composite waterproof cloth, it is set between the multiple layers of waterproof cloth.

[0090] The end of the metal crossbar 400 is inserted into the open slot and does not exceed the metal cable, while the portion of the edge of the flexible waterproof cloth 101 that exceeds the metal cable bypasses the metal cable and passes through the compression channel formed by the compression end and the fixed end.

[0091] The provision of the metal cross bar 400 can increase the stability of the flexible waterproof cloth during the water-blocking process. Since the application scenario is a section of a certain length, the water-blocking surface is rigidly graded, which can improve the water-blocking ability of the equipment and withstand greater water pressure.

[0092] The metal cross bar can be arranged on the outside (water-facing side) or the inside (water-back side) of the flexible waterproof cloth.

[0093] Continue to refer to the attached Figure 1, combined with a specific solution to illustrate the principle, the columns are separated on both sides of the base groove, the waterproof lifting structure 100 passes through the opening groove and is hung in the column. The specific hanging method is shown in the attached Figure 7 The waterproof layer of the waterproof lifting structure 100 is made of waterproof cloth, and the bottom side of the waterproof cloth is sealed in the base groove, specifically by pressing and sealing the metal plate with the base groove. At this time, the metal cable is located on the upper side of the sealed metal plate.

[0094] Specifically, a sealing strip is provided in the base groove, and a sealing strip is also provided on the compressed metal plate. The staggered design is used, and the metal plate is fixed to the base groove with bolts at equal intervals, and the bolts are located between the two sealing strips. The sealing mechanism is similar to that of the clip end, so I will not elaborate on it here.

[0095] As a preferred setting, a float switch is provided in the column, which is located on the inner wall of the column. When the structure is used, the height from the ground is 5-8 cm, preferably 5 cm.

[0096] The vertical columns on both sides of the waterproof cloth pass through the gap between the pressing end 42 and the fixing end 41. Under normal circumstances, the pressing clamp is in a loose state.

[0097] When work is required, the motor runs to drive the waterproof lifting structure to rise. The rising height is initially set by the control module (CPU) and can be 80cm or 100cm.

[0098] It is worth noting here that the height of the adjustable clamping structure in the column is lower than the height of the waterproof lifting structure, ensuring that the clamping structure can be fully clamped laterally, and the bottom side of the clamping structure is adjacent to the metal plate clamped on the bottom side of the machine base groove.

[0099] When it rises to the set height, the clamping fixture presses the waterproof cloth to form a waterproof seal inside the column, thus effectively waterproofing the underground garage.

[0100] The signal to start working can be given by a float switch or by manual operation.

[0101] For further explanation in combination with the usage scenario of the waterproof structure, please refer to the attached Figure 11 The waterproof structure is set in the water tank at the entrance of the basement. It can be an upslope water tank (on the right) or a downslope water tank (on the left). The water tank is the infrastructure and is connected to the municipal drainage pipeline.

[0102] Specifically, the base groove is set in the water tank 500, and the horizontal metal end of the L-shaped clip on it overlaps with the edge of the water tank 500 under normal circumstances. The L-shaped clip, as a metal part, fully meets the normal driving requirements of the garage entrance. The horizontal metal end of the L-shaped clip can be provided with a drainage hole.

[0103] When it rains and the water volume reaches the working standard of the waterproof structure, the float switch is triggered.

[0104] The waterproof lifting structure rises and the working process is as described above.

[0105] In this regard, the basement waterproofing can respond quickly, lift up the waterproofing in the early stage, and the personnel will quickly perform lateral sealing when they arrive at the scene, eliminating the need for sandbag transportation, metal plate transportation and other operations, with fast response and excellent results.

[0106] At the same time, in order to improve the aesthetics, a telescopic curtain structure can be set at the position of the opening groove, specifically located on the upper side of the waterproof lifting structure. The telescopic curtain can be a metal roller curtain structure or an elastic telescopic structure.
