Description

Technical Field

[0001] The invention relates to the technical field of expansion joint waterproofing, in particular to an external wall expansion joint waterproofing structure. Background Art

[0002] Exterior wall deformation joints can cause buildings to expand and contract due to temperature changes in different seasons and weather conditions. Exterior wall deformation joints can provide space for the expansion and contraction of wall materials, avoiding wall cracking and damage due to temperature changes. Exterior wall deformation joints are usually equipped with waterproof structures to prevent rainwater, groundwater, etc. from penetrating into the building.

[0003] The openings of the deformation joints of the exterior wall are usually covered with materials such as metal covers, rubber strips or plastic strips to protect the structure inside the joints from being affected by external factors. Traditional waterproof structures need to be installed on the same plane, but for deformation joints between the exterior wall and the ground or at the corners of the exterior wall, installation is inconvenient and the sealing effect cannot be guaranteed. Therefore, in view of this situation, the present invention proposes a novel waterproof structure for deformation joints of exterior walls. Summary of the invention

[0004] The object of the present invention is to provide a waterproof structure for an external wall deformation joint to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: an external wall deformation joint waterproof structure, comprising:

[0006] Waterproof structure 1, port piece, water-blocking piece and waterproof structure 2;

[0007] The waterproof structure 1 includes a bending plate, a wall plate and a pad. The bending plate is located between the wall plate and the pad. The middle of the bending plate is horizontally arranged. The two sides of the middle of the bending plate connected to the wall plate and the pad are inclined. The wall plate is vertically fixed to one side of the bending plate, and the pad is horizontally fixed to the other side of the bending plate.

[0008] Further to this solution, the wall plate is provided with a plurality of connecting grooves 1, which are in the shape of vertical straight grooves, and an insert plate is fixed at the bottom of the connection between the bending plate and the pad, and the insert plate is attached to the inner wall on one side of the deformation joint.

[0009] Further regarding this scheme, the waterproof structure 2 includes a cover plate, a support plate and a bent edge, and the cover plate, the support plate and the bent edge are also integrally formed. The support plate is fixed to one side of the cover plate and is perpendicular to the cover plate. The support plate is provided with a bayonet groove 1 corresponding to the position and number of the connecting through groove 1, and the bent edge is V-shaped and close to the ground.

[0010] Furthermore, regarding this solution, the width stop from the abutment plate to the bent edge is greater than the width of the edge of the siding plate of the waterproof structure.

[0011] Further to this solution, a plurality of connecting bolts are fixed to the side of the wall plate facing away from the ground, and the cover plate is provided with two connecting through grooves corresponding in number and position to the connecting bolts, and the two connecting through grooves are also in the shape of straight grooves.

[0012] Further regarding this scheme, the waterproof structure 2 is installed above the waterproof structure 1, and a cavity is formed between the cover plate and the bent plate of the waterproof structure 1 for filling with expansion sealant. The cover plate is provided with screw holes at a position above the bent plate to facilitate filling with expansion sealant, and plugging screws are threadedly installed at the screw holes.

[0013] Further regarding this scheme, the water barrier includes a baffle, a clamping plate and a bonding plate. The bonding plate is fixed to one side of the baffle and bent toward the ground. An angle less than 90° is formed between the bonding plate and the baffle. The bonding plate is also provided with a second bayonet slot corresponding to the number and position of the first bayonet slot. The second bayonet slot is also in the shape of a vertical straight slot. The clamping plate is fixed to a side away from the bonding plate and against the bend of the bent edge.

[0014] Further to this solution, a blocking piece is fixed on one side of the bonding plate, and the blocking piece abuts against the top of the wall-bonding plate to cover the gap between the wall-bonding plate, the abutting plate and the bonding plate.

[0015] Further regarding this solution, the port piece includes a seam plate, a side plate and a connecting key. The two sides of the seam plate are also inclined and are stuck in the deformation seam through deformation of the two sides. The connecting key is fixed between the seam plate and the side plate to reduce the contact area between the seam plate and the side plate, thereby ensuring the deformation effect of the seam plate.

[0016] Further to this solution, the port member is installed at both ends of the deformation joint and the clamping plate is located below the bending plate, wherein the side plate is set to have the same width as the deformation joint.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The waterproof structure of the external wall deformation joint is configured by waterproof structure one, waterproof structure two and water-blocking parts. This waterproof structure is suitable for situations where the base surfaces on both sides of the deformation joint are not on the same base surface, such as between the external wall and the ground and in the sedimentation gap of the external wall. It solves the problem that the traditional structure requires the base surfaces on both sides to be on the same plane and is difficult to apply. In addition, waterproof structure two can cover waterproof structure one to form double water protection. The bent edge is V-shaped and close to the ground to reduce water entering from the gap. The cavity between the cover plate and the bent plate can be filled with expansion sealant to further improve the waterproof effect.

[0019] At the same time, through the setting of the plug plate, the contact area on one side of the bent plate is increased, the friction is improved, and the bent plate can be placed in the deformation joint in a relatively stable state. After the water-blocking card is clamped on the bent edge, it can press the bent edge, and then press one side of the pad of the waterproof structure, thereby increasing the pressure of the pad pressing the ground, improving the stability of this side of the pad, and reducing the difficulty of installation.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1 As shown, Figure 1 The figure shows a common expansion joint waterproof structure on the market. This structure is achieved by laying a waterstop a on the bottom layer, pressing the waterproof base b on both sides of the expansion joint, and sliding the stainless steel waterproof plate c on the waterproof base b. When the expansion joint of the wall becomes larger, the waterstop a follows the deformation, and the stainless steel waterproof plate c is slidably connected to the waterproof base b, which satisfies the requirement that when the expansion joint becomes larger, the waterstop a and the stainless steel waterproof plate c can always cover the expansion joint, and can achieve excellent waterproof effect. This situation is applicable when the base surfaces on both sides of the expansion joint are on the same plane. When the base surfaces on both sides are not on the same plane, such as between the outer wall and the ground and in the sedimentation joints of the outer wall, the above structure is difficult to apply because it requires the base surfaces on both sides to be on the same plane.

[0031] like Figure 2 As shown, the present invention provides a technical solution: an external wall deformation joint waterproof structure, comprising a waterproof structure 1, a port piece 2 and a waterproof structure 2 3, the deformation joint waterproof structure is installed when the base surfaces on both sides of the deformation joint are not on the same base surface, the waterproof structure 1 is installed on the external wall or on a side base surface that is perpendicular to the horizontal plane (hereinafter referred to as the vertical side base surface), and is in contact with another wall or a side base surface that is horizontal to the horizontal plane (hereinafter referred to as the horizontal side base surface), the port piece 2 is installed at both ends of the waterproof structure 1, the waterproof structure 2 3 is installed on the waterproof structure 1, and the waterproof structure 1, the port piece 2 and the waterproof structure 1 form a sealed waterproof structure at the deformation joint.

[0032] Combination Figure 2 and Figure 3The waterproof structure 1 includes a bending plate 101, a wall plate 102 and a pad 104. The bending plate 101 is located between the wall plate 102 and the pad 104. The bending plate 101, the wall plate 102 and the pad 104 are integrally formed. The wall plate 102 is attached to the surface of the vertical side base surface. The bending plate 101 is located in the deformation joint. The pad 104 is attached to the surface of the horizontal side base surface and an inclined surface 105 is provided at the edge. Compared with the vertical surface, the inclined surface 105 has a better water isolation effect. The wall plate 102, the bending plate 101 and the pad 104 form a covering waterproof structure from the vertical side base surface to the horizontal side base surface. The waterproof structure 1 is made of stainless steel as a whole. Therefore, the waterproof structure The waterproof structure 1 as a whole has a certain deformation ability. From the cross-sectional perspective, the middle part of the bending plate 101 is horizontally arranged, and the sides of the middle part of the bending plate 101 connected to the wall plate 102 and the pad 104 are inclined. That is to say, combined with the overall material of the waterproof structure 1, the bending plate 101 has a better deformation effect. During the installation process, the bending plate 101 is in a compressed state and is located in the deformation joint. In other words, when the bending plate 101 is installed, the inclined sides on both sides of the bending plate 101 are bent inward to a certain extent. Then, when the deformation joint becomes larger and expands, the bending plate 101 can meet the enlargement demand of the deformation joint, so that the waterproof structure 1 can always cover the deformation joint.

[0033] like Figure 4 As shown, as an alternative embodiment of the above embodiment, it is necessary to know that the middle part of the bending plate 101 is horizontally arranged, and the sides of the middle part of the bending plate 101 connected to the wall plate 102 and the pad 104 are both vertically arranged. That is to say, combined with the overall material of the waterproof structure 1, the bending plate 101 can fit the two side walls of the deformation joint, and the stabilization effect is better. Compared with the bending plate 101 with inclined sides, the processing technology of the two sides being vertical is simpler.

[0034] like Figure 5 As shown, as an alternative embodiment to the above embodiment, it is necessary to know that the bending plate 101 is in an arc shape. In combination with the above embodiment, the two sides of the bending plate 101 can be set at an angle, can be set vertically, or the bending plate 101 can be set to an arc shape. In other words, the bending plate 101 can be designed to have any cross-sectional shape according to the actual situation of the deformation joint to provide a more stable waterproof effect.

[0035] Combination Figure 2 and Figure 4, several positioning bolts 5 are embedded in the vertical side base surface, and the positioning bolts 5 are expansion bolts. A connecting groove 103 corresponding to the number of the positioning bolts 5 is opened on the siding plate 102. The waterproof structure 1 can be fixed by connecting the connecting groove 103 with the positioning bolts 5 and fixing them with nuts. It should be understood that the connecting groove 103 is in the shape of a vertical straight groove and the groove diameter matches the diameter of the positioning bolts 5. That is to say, after the waterproof structure 1 is connected with the positioning bolts 5, the shape of the connecting groove 103 allows the waterproof structure 1 to move in the vertical direction to a certain extent. This method allows the pad 104 to be tightly attached to the horizontal side base surface, reducing the requirements for the bolt pre-embedded accuracy. A plug plate 106 is fixed at the bottom of the connection of 04, and the plug plate 106 is attached to a side wall of the deformation joint close to the horizontal side base surface, and one side of the waterproof structure 1 is fixed to the vertical side base surface by bolts. That is to say, if you want the bent plate 101 part of the waterproof structure 1 to be in a compressed and deformed state in the deformation joint, you must apply force on the other side of the waterproof structure 1 to deform the bent plate 101. However, one side of the bent plate 101 is inclined, which means that the bent plate 101 and the deformation joint do not have enough contact area to support the bent plate 101 to remain stable after deformation. By setting the plug plate 106, the contact area on one side of the bent plate 101 is increased, the friction is increased, and the bent plate 101 can be placed in the deformation joint in a relatively stable state.

[0036] Combination Figure 2 and Figure 6In order to further improve the waterproof effect of the waterproof structure, the waterproof structure 23 includes a cover plate 301, a butt plate 305 and a bent edge 303. The cover plate 301, the butt plate 305 and the bent edge 303 are also made of stainless steel in one piece. The butt plate 305 is fixed to one side of the cover plate 301 and is perpendicular to the cover plate 301. The butt plate 305 is provided with a bayonet groove 1 306 corresponding to the number of the positioning bolts 5. The width of the bayonet groove 1 306 is adapted to the diameter of the positioning bolt 5. The waterproof structure 23 is installed at the positioning bolt 5 through the bayonet groove 1 306 of the butt plate 305. The width from the butt plate 305 to the bent edge 303 is at least greater than the width from the wall plate 102 of the waterproof structure 1 to the edge of the pad 104. That is to say, the waterproof structure 23 It can cover the waterproof structure 1 to form double water protection. A number of connecting bolts 107 are fixed on the siding plate 102. A connecting through groove 2 304 corresponding in number and position to the connecting bolts 107 is opened on the cover plate 301. The connecting through groove 2 304 is also in the shape of a straight slot, which is convenient for the installation of the cover plate 301 and reduces the difficulty in installation caused by the difficulty in aligning the holes. The bent edge 303 is fixed to the side away from the abutment 305. The bent edge 303 is V-shaped and close to the ground to reduce the entry of water from the gap at the bent edge 303. After the waterproof structure 2 3 and the waterproof structure 1 are installed, a sealing strip 6 is provided between the cover plate 301 close to the vertical side base and the bent plate 101 to improve the sealing effect.

[0037] The waterproof structure 2 3 is installed above the waterproof structure 1 , and a cavity is formed between the cover plate 301 and the bent plate 101 of the waterproof structure 1 , and the cavity can be used to fill with an expansion sealant to further improve the waterproof effect of the waterproof structure. A screw hole 302 is provided at a position above the bent plate 101 of the cover plate 301 for installing a plugging screw 7, and the plugging screw 7 can be removed to fill the expansion sealant from the screw hole 302.

[0038] Combination Figure 2 and Figure 7The water barrier 4 includes a baffle 401, a clamping plate 402 and a bonding plate 403. The bonding plate 403 is fixed to one side of the baffle 401 and bent toward the ground. An angle less than 90° is formed between the bonding plate 403 and the baffle 401. The bonding plate 403 is also provided with a second bayonet slot 404 corresponding to the number and position of the positioning bolts 5. The second bayonet slot 404 is also in the shape of a vertical straight slot. The water barrier 4 is aligned with the positioning bolts 5 through the second bayonet slot 404. Then the water barrier 4 is fixed, that is, when the water barrier 4 is installed, the top surface of the baffle 401 is inclined away from the vertical side base surface, and rainwater falls on the baffle 401 and naturally slides off the baffle 401 under the effect of gravity, avoiding the accumulation of rainwater in the waterproof structure. The card plate 402 is fixed to the side away from the bonding plate 403. When the water barrier 4 is installed, the card plate 402 is against the bend of the bent edge 303 to keep the stability of the entire water barrier 4.

[0039] Combination Figure 6 and Figure 7 What needs to be understood in the above embodiment is that the waterproof structure 1 is fixed by connecting with the vertical side base surface, that is to say, in the case of such unilateral fixation, the stability of one side of the pad 104 is relatively poor, and the baffle 401 of the water barrier 4 is inclined and is also made of stainless steel, and also has a certain deformation effect. Therefore, after the water barrier 4 is installed, the clamping plate 402 is clamped on the bent edge 303, and the clamping plate 402 can have a pressing effect on the bent edge 303. In this case, the bent edge 303 can be close to the ground. The waterproof structure 23 is installed on the waterproof structure 1, so that one side of the pad 104 of the waterproof structure 1 is pressed, thereby increasing the pressure of the pad 104 pressing the ground, and also increasing the stability of this side of the pad 104.

[0040] A baffle 405 is fixed on the side of the bonding board 403 facing the vertical side base surface. After the waterproof component 4 is installed, the baffle 405 is against the top of the wall board 102, which can isolate the gap between the wall board 102, the abutment plate 305 and the bonding board 403, prevent rainwater from invading from the gap, and improve the waterproof effect.

[0041] Combination Figure 2 and Figure 8The port member 2 includes a seam plate 201, a side plate 203 and a connecting key 202. The port member 2 is also made of stainless steel as a whole. The seam plate 201 is inclined on both sides like the bending plate 101, and is stuck in the deformation seam through the deformation effect. The connection of the connecting key 202 can reduce the contact area between the seam plate 201 and the side plate 203, ensuring the deformation effect of the seam plate 201. The side plate 203 is a plate body with the same width as the deformation seam, which is vertically inserted into the deformation seam and tightly attached to the end walls at both ends of the deformation seam. After the waterproof structure is installed, the two ends of the waterproof structure 1 are respectively in contact with the side plates 203 at both ends of the deformation seam to increase the tight connection effect and improve the sealing.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the attached embodiments and their equivalents.
