Description
Technical Field
The invention relates to the technical field of waterproof repair, in particular to a waterproof repair method and a waterproof repair structure for a roof wall root.
Background
Whether it is a tunnel, a bridge, a dam, a road, a building or a house which people live in daily life, the waterproof is a problem which cannot be ignored. The main structures of house buildings include foundations, walls, columns, buildings, floors, balconies, awnings, stairs, doors and windows, building roofs and the like, and the structures closely related to water proofing are building roofs, walls of main structures, foundations, floors, doors and windows, stairs, balconies and awnings. The roof is arranged on the top of the building and mainly used for preventing rain (snow) water and ultraviolet rays from entering a room and insulating the room. The structure of the building mainly comprises a structural layer, a slope finding layer, a leveling layer, a steam barrier layer, a heat preservation layer, a waterproof layer, a protective layer, a ventilation and heat insulation layer or a veneer and the like. Because of the needs of buildings, the roof is often provided with a water outlet, an air outlet, a chimney, an access hole, a skylight and a tiger window, or the roof is provided with equipment or used as a swimming pool, a sports ground, an apron and the like, so the roof structure is relatively complex and has high waterproof requirements.
The roof of a building is generally provided with short walls, called parapet walls and grandson parapet walls, around the roof, which mainly have the main functions of maintaining safety, and applying waterproof pressed bricks at the bottom to prevent water seepage of a waterproof layer or overflow of rainwater on the roof. The parapet wall on the roof of the person is used for protecting the safety of the person and has a decorative effect on the building facade. The parapet wall without a roof has the function of fixing the asphalt felt besides the function of facade decoration. According to the national building code, the height of the parapet wall on the roof of the upper part of the house is generally not less than 1.1m and not more than 1.5m at most.
As is well known, the waterproof material has aging characteristics, and after a building is used for a certain period of time, the phenomenon of water leakage and water seepage caused by the aging of a waterproof layer is inevitable, so that the parapet cannot be used, especially the joint of the parapet and a flat roof, and therefore, the waterproof material is an important part for the waterproof repair of the existing building besides the waterproof design of the roof of a newly-built building. For the waterproof repairing of the parapet and the joint of the parapet and the flat roof, the prior art generally only focuses on the waterproofing and repairs or replaces the waterproof layer, but the influence of the bonding strength of the parapet and the flat roof on the service life of the waterproof layer is not considered, and the influence is exactly a key factor influencing the waterproof repairing effect. Therefore, there is a need for a method of repairing a roof wall root.
Disclosure of Invention
In view of the above, the present invention provides a method for repairing a waterproof roof wall root and a waterproof roof wall root repairing structure formed thereby, which overcome at least one of the above-mentioned deficiencies in the prior art, and solve the problem that the existing waterproof roof wall root repairing method only focuses on waterproofing, but does not pay attention to the structure itself, which affects the service life of the waterproof repairing method, thereby improving the effective service life of the waterproofing.
In order to solve the technical problems, the invention adopts the following technical scheme:
a method for repairing a water-proof wall root of a roof, wherein the wall root comprises a flat roof and a vertical surface structure connected with the flat roof at an angle, comprises the following steps:
s1, excavating a flat roof at the joint of the flat roof and a vertical surface structure to form a seam between the flat roof and the vertical surface structure;
s2, cleaning the flat roof, the vertical surface structure and the seam surface obtained by the excavation in the step S1;
and S3, paving the waterproof coiled material on the surfaces of the flat roof and the vertical surface structure, and putting one or more of waterproof materials, buffer materials and reinforcing materials into the seams during or before paving.
According to the invention, before the waterproof coiled material is laid, the flat roof close to the vertical surface structure is chiseled, so that a seam which can be filled with waterproof materials, buffer materials or reinforcing materials is formed between the flat roof and the vertical surface structure, accumulated water is promoted to be rapidly removed through filling of the waterproof materials, the thrust of the vertical surface structure of the flat roof is reduced through filling of the buffer materials, the bonding force between the vertical surface structure and the flat roof is enhanced through filling of the reinforcing materials, and the reliability of water resistance and the service life are improved from different dimensions. The flat roof comprises a structural layer and a surface layer positioned on the structural layer; the facade structure is a patio or a parapet.
When the vertical surface structure is a patio, in step S1, the surface layer of the flat roof is excavated at the joint of the flat roof and the patio until the structural layer of the flat roof leaks out, so that the seam is formed between the surface layer of the flat roof and the patio.
In step S3, a waterproof material is placed in the gap when the waterproof roll is laid, the waterproof material is the waterproof roll for laying the flat roof and the patio, and the middle part of the waterproof roll is pressed into the gap when the waterproof roll is laid on the surfaces of the flat roof and the patio. The invention forms a seam at the joint of the courtyard and the flat roof by excavating the flat roof, and plugs the middle section of the waterproof coiled material which is paved on the surface in the seam in the past, namely, when the waterproof coiled material is paved, two ends of the waterproof coiled material are respectively paved on the flat roof and the vertical surface of the courtyard, and the middle section of the waterproof coiled material which is paved on the flat roof and the vertical surface of the courtyard is reserved in the seam between the flat roof and the vertical surface of the courtyard for enough length, and then the specially reserved middle section of the waterproof coiled material is plugged into the seam formed by excavation, so that the waterproof coiled material is not easy to be pulled mutually between the plane and the vertical surface, the attaching degree of the waterproof coiled material between the flat roof and the vertical surface of the courtyard is improved, more importantly, the seam excavation and the press-in laying of the waterproof coiled material can form a tiny water collecting ditch between the vertical surface of the courtyard and the flat, and ultimately to a drain for removal. Preferably, the width of seam is 5 ~ 30mm, can enough satisfy waterproof roll's filling in, can form tiny catch basin again after waterproof roll fills in, promotes dredging and discharging of ponding on the flat roof.
In order to prevent the seeper which is guided to flow to the water collecting ditch formed by the seams from seeping into the waterproof layer formed by the waterproof coiled material, the tail end of the waterproof coiled material laid on the surface of the patio is higher than the surface of the flat roof, so that the seeper is prevented from forming seepage seams due to the fact that the waterproof coiled material is soaked for a long time when the seams stay, the seepage seams are formed due to the fact that the waterproof coiled material is degummed, and then the seeper seeps into the lower portions of the waterproof coiled material through the seepage seams. Preferably, the tail end of the waterproof coiled material paved on the surface of the courtyard is 200-500 mm higher than the surface of the flat roof.
The waterproof roll laid on the surface of the patio is laid along the vertical surface, the tail end of the waterproof roll faces the sky, once the waterproof roll is not firmly adhered to the vertical surface of the patio, water vapor possibly permeates into the patio structure from the position, for this purpose, in step S3, the tail end of the waterproof roll laid on the vertical surface of the patio is cut into the patio, namely, a gap with an opening inclining downwards is formed in the vertical surface of the patio, and the tail end of the waterproof roll is plugged into the gap.
When the vertical face structure is a parapet, in step S1, the flat roof is excavated at the joint of the flat roof and the parapet, and the flat roof is excavated to the structural layer of the flat roof, so that a V-shaped groove is formed between the structural layer of the flat roof and the parapet, a newly-made gutter is formed between the flat roof above the V-shaped groove and the parapet, and the V-shaped groove and the newly-made gutter together form the seam. The newly-made gutter can be formed between the vertical surface structure and the flat roof surface layer or between the vertical surface structure and the flat roof comprising the surface layer and the structural layer, namely the newly-made gutter can be formed by chiseling the flat roof surface layer or chiseling the flat roof surface layer and part of the structural layer.
For the existing building needing waterproof repair, the construction time is not too short, fine cracks are difficult to avoid between the parapet wall and the flat roof, which is the neglected part in the existing waterproof repair technology and is also a symptom that the waterproof repair structure cannot obtain longer validity period, the existence of the cracks makes the binding force between the parapet wall and the flat roof insufficient, the waterproof layer at the position is weak because the waterproof layer is easy to be pulled by the waterproof coiled material formed between the parapet wall and the flat roof due to the mutual deviation of the parapet wall and the flat roof, once the waterproof layer fails, accumulated water is easy to permeate into the building through the gradually enlarged cracks, therefore, in step S3, before the waterproof coiled material is laid on the vertical surface of the flat roof and the parapet wall, a reinforcing material is filled in the V-shaped grooves to strengthen the binding force between the parapet wall and the flat roof structure layer. According to the invention, before the waterproof coiled material is laid, the surface layer and part of the structural layer of the flat roof close to the parapet are chiseled off, so that a V-shaped groove capable of being filled with the reinforcing material is formed between the flat roof and the parapet, the bonding force between the parapet and the structural layer of the flat roof is enhanced through the filling of the reinforcing material, the stable bonding between the parapet and the flat roof is ensured, the mutual deviation caused by cracking or insufficient bonding force between the parapet and the flat roof is avoided, the waterproof structure is finally damaged due to the pulling of the waterproof coiled material laid on the surface, the waterproof reliability is improved, and the service life is prolonged.
In order to prevent the flat roof from forming an outward thrust on the parapet, in step S3, before or after the waterproof roll is laid, a buffer material is filled in the newly-made gutter to form a buffer layer between the parapet and the flat roof. The buffer layer not only fills up a newly-made gutter to enable the flat roof to recover to be flat, but also prevents the flat roof from forming outward thrust on the parapet wall, and further improves the protection effect on the waterproof layer. In the case that the newly-made gutter is formed between the vertical face of the parapet wall and the surface layer of the roof, the workload of chiseling the newly-made gutter is small, and the construction period of repair engineering is shortened; meanwhile, because the thickness of the flat roof surface layer is generally smaller, the depth of a newly-made gutter formed by chiseling the flat roof surface layer is correspondingly smaller, and in order to ensure that the buffer layer can actually play a corresponding buffer role, the buffer layer is preferably formed between the parapet wall below the waterproof roll and the flat roof; in addition, in order to avoid the corners of the waterproof roll material formed between the buffer layer and the parapet from being pressed and broken or not adhered to the wall body and stressed, the buffer material is continuously filled between the buffer layer and the parapet to form a first transition fillet, so that the waterproof roll material can be laid at the position and tightly adhered to the first transition fillet, the waterproof roll material cannot be broken, the waterproof roll material can be prevented from being pulled by stress, the service life of the waterproof roll material is further prolonged, and the effective service life of the waterproof repairing structure is prolonged. For the situation that a newly-made gutter is formed between the parapet and the flat roof comprising the surface layer and the structural layer, the buffer layer is preferably formed between the parapet and the flat roof on the waterproof roll, namely the waterproof roll is paved before the buffer material is filled, and the buffer layer is formed on the waterproof layer, so that the water on the flat roof is led to the newly-made gutter, and the surface accumulated water is promoted to be quickly discharged; in addition, in order to prevent the corners formed between the V-shaped grooves filled with the reinforcing materials and the parapet from being broken due to compression or being stressed without being adhered to a wall body, second transition fillets formed by buffer materials are filled between the upper surfaces of the V-shaped grooves and the parapet, so that the waterproof roll can be laid at the positions close to the second transition fillets, the waterproof roll cannot be broken due to the second transition fillets, the waterproof roll can be prevented from being pulled due to stress, the service life of the waterproof roll is further prolonged, and the effective service life of the waterproof repairing structure is further prolonged.
The waterproof coiled material laid on the parapet wall surface is laid along the vertical surface, the tail end of the waterproof coiled material faces the sky, once the waterproof coiled material is not firmly adhered to the parapet wall vertical surface, water vapor possibly permeates into the parapet wall structure from the position, therefore, in step S3, the tail end of the waterproof coiled material laid on the parapet wall vertical surface at least extends to the top of the parapet wall and cuts into the parapet wall, namely, a gap is formed in the top of the parapet wall or the vertical surface deviating from a flat roof, the tail end of the waterproof coiled material is plugged into the gap, then the waterproof coiled material is matched and fixed by a metal pressing strip and a cement nail, and then the waterproof coiled material is sealed by.
The invention also provides a waterproof repairing structure for the wall root of the roof, wherein the wall root comprises a flat roof and a vertical surface structure connected with the flat roof at an angle, a seam formed by excavating the flat roof is arranged between the flat roof and the vertical surface structure, one or more of waterproof materials, buffer materials and reinforcing materials are filled in the seam, and waterproof coiled materials are laid on the surfaces of the flat roof and the vertical surface structure.

Preferably, the width of seam is 5 ~ 30mm, can enough satisfy waterproof roll's filling in, can form tiny catch basin again after waterproof roll fills in, promotes dredging and discharging of ponding on the flat roof.
In order to prevent the seeper which is guided to flow to the water collecting ditch formed by the seams from seeping into the waterproof layer formed by the waterproof coiled material, the tail end of the waterproof coiled material laid on the surface of the patio is higher than the surface of the flat roof, so that the seeper is prevented from forming seepage seams due to the fact that the waterproof coiled material is soaked for a long time when the seams stay, the seepage seams are formed due to the fact that the waterproof coiled material is degummed, and then the seeper seeps into the lower portions of the waterproof coiled material through the seepage seams. Preferably, the tail end of the waterproof coiled material paved on the surface of the courtyard is 200-500 mm higher than the surface of the flat roof.
The waterproof coiled material laid on the surface of the patio is laid along the vertical face, the tail end of the waterproof coiled material faces the sky, once the waterproof coiled material is not firmly adhered to the vertical face of the patio, water vapor possibly permeates into the patio structure from the position, for this purpose, the tail end of the waterproof coiled material laid on the vertical face of the patio is cut into the patio, namely, a gap with an opening inclining downwards is formed in the vertical face of the patio, and the tail end of the waterproof coiled material is plugged into the gap.
When the facade structure is the parapet, the seam is including the V-arrangement groove that forms between the structural layer of flat roofing and the parapet and the new gutter of making between the flat roofing that forms on the V-arrangement groove and the parapet, the new gutter of making can be formed between facade structure facade and roofing top layer, also can be formed between facade structure and including top layer and structural layer roofing, promptly the new gutter of making can be formed through chiseling roofing top layer, also can form through chiseling roofing top layer and partial structural layer.

According to the invention, the flat roof 100 close to the vertical surface structure is chiseled before the waterproof coiled material is laid, so that a seam 400 capable of being filled with waterproof materials, buffer materials or reinforcing materials is formed between the flat roof 100 and the vertical surface structure, accumulated water is promoted to be rapidly removed through filling of the waterproof materials, the thrust of the vertical surface structure of the flat roof 100 is reduced through filling of the buffer materials, and the bonding force between the vertical surface structure and the flat roof 100 is enhanced through filling of the reinforcing materials, so that the waterproof reliability is improved from different dimensions, and the service life is prolonged. The flat roof 100 includes a structural layer 110 and a surface layer 120 on the structural layer 110; the facade structure is a patio 220 or a parapet.
Example 2
This embodiment is an improvement of the structure of the facade as the patio 220 in embodiment 1.
As shown in fig. 3 to 7, in step S1, the surface layer 120 of the flat roof 100 is excavated at the joint between the flat roof 100 and the patio 220 until the structural layer 110 of the flat roof 100 leaks out, so that the seam 400 is formed between the surface layer 120 of the flat roof 100 and the patio 220.
In step S3, a waterproof material is placed in the slit 400 when a waterproof roll is laid, the waterproof material is the waterproof roll for laying the flat roof 100 and the patio 220, and the middle part of the waterproof roll is pressed into the slit 400 when the waterproof roll is laid on the surfaces of the flat roof 100 and the patio 220. In the invention, a seam 400 is formed at the joint of the courtyard 220 and the flat roof 100 by excavating the flat roof 100, and the middle section of the waterproof coiled material which is paved on the surface in the past is plugged into the seam 400, namely, when the waterproof coiled material is paved, two ends of the waterproof coiled material are respectively paved on the vertical surfaces of the flat roof 100 and the courtyard 220, and a long enough waterproof coiled material middle section which is not paved on the flat roof 100 and the vertical surface of the courtyard 220 is reserved at the seam 400 between the vertical surfaces of the flat roof 100 and the courtyard 220, and then the specially reserved waterproof coiled material middle section is plugged into the seam 400 formed by excavation, so that the waterproof coiled material is not easy to pull between the plane and the vertical surface, the attaching degree of the waterproof coiled material between the flat roof 100 and the vertical surfaces of the courtyard 220 is improved, more importantly, a fine water collecting ditch can be formed between the vertical surfaces of the courtyard 220 and the flat roof 100 by the excavation of the, it is advantageous to direct the accumulated water to flow towards the seam 400 and finally towards the drain pipe to be drained away.

Example 3
This embodiment is an improvement of the structure of the facade described in embodiment 1 as a parapet wall.
As shown in fig. 8 to 12, in step S1, the flat roof 100 is excavated at the joint between the flat roof 100 and the parapet wall, the construction layer 110 of the flat roof 100 is excavated to form a V-shaped groove 410 between the construction layer 110 of the flat roof 100 and the parapet wall, a new gutter 420 is formed between the flat roof 100 and the parapet wall above the V-shaped groove 410, and the V-shaped groove 410 and the new gutter 420 together form the seam 400. The newly fabricated gutter 420 may be formed between the vertical surface structure and the flat roof surface layer 120, or between the vertical surface structure and the flat roof 100 including the surface layer 120 and the structural layer 110, that is, the newly fabricated gutter 420 may be formed by chiseling the flat roof surface layer 120, or may be formed by chiseling the flat roof surface layer 120 and a part of the structural layer 110.
For the existing building needing waterproof repair, the construction time is not too short, fine cracks are inevitably generated between the parapet wall and the flat roof 100, which is the neglected part in the existing waterproof repair technology and is also the symptom that the waterproof repair structure cannot obtain longer validity period, the existence of the cracks makes the bonding force between the parapet wall and the flat roof 100 insufficient, the waterproof layer at the position is weak because the waterproof layer is pulled between the parapet wall and the flat roof 100 due to the mutual deviation of the parapet wall and the flat roof, and once the waterproof layer fails, water is easy to permeate into the building through the gradually enlarged cracks, therefore, in the step S3, before the waterproof roll material is laid on the vertical surface of the flat roof 100 and the parapet wall, the reinforcing material is filled in the V-shaped grooves 410 to strengthen the bonding force between the parapet wall and the flat roof structure layer 110.
