Description

Technical Field

[0001] This application relates to the field of waterproof construction, and particularly to a waterproof construction method. Background Art

[0002] Buildings need to be waterproofed whether it is the basement, roof or bathroom. According to the design requirements of the waterproof grade, corresponding waterproofing measures and different types of materials are used for waterproofing or moisture-proofing. For the ground waterproof project, a cement mortar layer is usually laid on the surface of the ground base layer and leveled, and then a layer of waterproof coating is applied on the cement mortar layer to form a waterproof layer. Finally, tiles are pasted on the waterproof layer to complete the waterproof project. At the same time, at the pipe position, there may be certain gaps at the contact points between the pipes and the walls, and waterproof construction is also required.

[0003] In the prior art, when applying waterproof coating manually, when the operator sprays the waterproof coating on the waterproof part of the corner, the horizontal level and spraying area of each position of the waterproof layer may be inconsistent due to manual errors. At the same time, when the operator sprays the waterproof coating around the pipe, it is necessary to manually level the waterproof coating, which may cause the waterproof coating to be uneven and thus affect the waterproof effect. Summary of the Invention

[0004] In order to improve the flatness of the waterproof coating and the project quality, this application provides a waterproof construction method.

[0005] A waterproof construction method provided by this application adopts the following technical solutions: including the following steps:

[0006] S1. Clean the garbage on the ground base layer;

[0007] S2. Make caulking treatment at the pipe root according to the requirements;

[0008] S3. Treat the internal and external corners to be arc-shaped;

[0009] S4. Level the treated ground, and fill and level the uneven positions with cement mortar;

[0010] S5. Prepare the acrylic polymer cement-based waterproof slurry;

[0011] S6. Spray the waterproof coating on the wall corners and pipe roots through a waterproof construction device. For the wall treatment, apply more than 30 cm of waterproof coating to prevent water accumulation from seeping through the wall and causing dampness;

[0012] S7. Spray the waterproof coating on the ground and conduct a water storage test;

[0013] S8. Lay tiles and other protective layers;

[0014] S9. Fill the joints of the tiles and other protective layers with filler while ensuring the smoothness of the protective layer.

[0015] By adopting the above technical solutions, after the construction personnel process the ground flatness, the cracking and leakage caused by uneven thickness of the waterproof coating are reduced. High-elastic flexible waterproof coating should be used to brush the joints such as floor drains, corners, and pipe roots to reduce water seepage. The waterproof coating is sprayed on the corners and pipe joints through the waterproof construction device, which can ensure the smoothness of the waterproof coating and the construction quality.

[0016] Preferably, a waterproof construction device includes a first mounting seat and a second mounting seat. A spray head for spraying waterproof coating is provided on the first mounting seat. The first mounting seat is hinged to the second mounting seat. Universal wheels for assisting their movement along the wall edge are provided on both the first mounting seat and the second mounting seat. A plurality of driving wheels for driving the first mounting seat and the second mounting seat to rotate around the pipe are provided on the second mounting seat. An adjustment assembly for adjusting the clamping radius of the driving wheels is provided on the first mounting seat.

[0017] By adopting the above technical solutions, when the construction personnel spray the waterproof coating at the corner, the operator rotates the first mounting seat so that the axes of the first mounting seat and the second mounting seat are perpendicular. The first mounting seat is in contact with the ground, and the second mounting seat is in contact with the wall. At the same time, the spray head is adjusted to aim at the corner, and the spray head is turned on. The operator moves the first mounting seat at a uniform speed so that the waterproof coating sprayed by the spray head can evenly reach the designated position. When the construction personnel spray the waterproof coating at the pipe joint, the operator unfolds the first mounting seat and the second mounting seat, slews the first mounting seat and the second mounting seat on the pipe, adjusts the angle of the spray head so that the spray head aims at the pipe joint, and moves the first mounting seat and the second mounting seat so that the spray head aims at the pipe joint. The spray head is started, and the first mounting seat and the second mounting seat are rotated so that the first mounting seat and the second mounting seat rotate around the pipe. At this time, the waterproof coating sprayed by the spray head can be evenly laid on the pipe joint.

[0018] Preferably, support seats are slidably arranged on both the first mounting seat and the second mounting seat. A support column is slidably penetrated through the support seat. A first chute for slidably cooperating with the support column is formed on the support seat. The driving wheel is sleeved on the support column. A motor is provided on the support seat. The output end of the motor is fixedly connected to the support column. A buffer spring is provided at the end of the support column located in the first chute. The end of the buffer spring away from the support column is fixedly connected to the inner end wall of the first chute.

[0019] By adopting the above technical solution, when the adjusting component adjusts the clamping radius of a number of driving wheels, the motor drives the support column to rotate. The rotation of the support column causes the driving wheel to rotate, and the driving wheel causes the first mounting seat and the second mounting seat to start rotating around the pipeline. At this time, the nozzle can evenly spray waterproof coating on the pipeline joint. The buffer spring can maintain the friction force when the driving wheel contacts the pipeline. When the driving wheel rotates and causes the first mounting seat and the second mounting seat to rotate around the pipeline, the buffer spring can reduce and avoid slipping.

[0020] Preferably, the adjusting component includes a lead screw. The lead screw passes through both the first mounting seat and the second mounting seat. The lead screw passes through the support seat, and the lead screw is in threaded cooperation with the support seat. A first driving component for driving the lead screw to rotate is arranged in the first mounting seat.

[0021] By adopting the above technical solution, the first driving component drives the lead screw to rotate. The rotation of the lead screw causes the support seat to move, and the movement of the support seat causes the support column and the driving wheel to move, thereby adjusting the clamping radius of a number of driving wheels.

[0022] Preferably, the first driving component includes a first gear ring and a second gear ring. A second sliding groove for slidingly cooperating with the first gear ring and the second gear ring is formed in the first mounting seat. A third sliding groove for slidingly cooperating with the first gear ring and the second gear ring is formed in the second mounting seat. The second sliding groove is communicated with the third sliding groove. Magnets are arranged at the ends of the first gear ring and the second gear ring that are close to each other. A first spur gear is fixedly sleeved on the lead screw. Both the first gear ring and the second gear ring can mesh with the first spur gear.

[0023] By adopting the above technical solution, when the nozzle sprays waterproof coating on the pipeline joint, the construction worker rotates the first gear ring. The rotation of the first gear ring causes the second gear ring to rotate. The rotation of the first gear ring and the second gear ring causes the first spur gear to rotate. The rotation of the first spur gear causes the lead screw to rotate. The rotation of the lead screw causes the support seat to move, and the movement of the support seat causes the support column and the driving wheel to move, thereby adjusting the clamping radius of a number of driving wheels. When the operator performs waterproof construction on the corner of the wall, the operator needs to rotate the first mounting seat and the second mounting seat to form a certain angle. When the operator rotates the first mounting seat, the first gear ring and the second gear ring are separated. When constructing the pipeline, the operator recombines the first mounting seat and the second mounting seat. At this time, the first gear ring and the second gear ring come into contact again. Under the action of the magnet, the first gear ring and the second gear ring are combined to form a complete gear ring.

[0024] Preferably, a first driving rod is inserted into the first mounting seat. The first driving rod penetrates into the first mounting seat. A second straight gear is fixedly sleeved on the first driving rod. Both the first gear ring and the second gear ring can be meshed with the second straight gear.

[0025] By adopting the above technical solution, the operator rotates the first driving rod. The rotation of the first driving rod causes the second straight gear to rotate. The rotation of the second straight gear causes the first gear ring and the second gear ring to rotate. The rotation of the first gear ring and the second gear ring causes the first straight gear to rotate. The rotation of the first straight gear causes the lead screw to rotate. The rotation of the lead screw causes the support seat to move, thereby changing the clamping radius of the driving wheel.

[0026] Preferably, a scraper for leveling the waterproof coating is arranged on the first mounting seat. A rotating shaft is inserted into the first mounting seat. The rotating shaft is rotatably connected to the first mounting seat. The rotating shaft penetrates into the scraper. A cross groove for slidingly cooperating with the rotating shaft is formed on the scraper. A second driving assembly for driving the rotating shaft to rotate is arranged on the first mounting seat.

[0027] By adopting the above technical solution, when the nozzle sprays the waterproof coating on the corner of the wall, at this time, a certain included angle is formed between the axes of the first mounting seat and the second mounting seat. The scraper is perpendicular to the wall at this time. When the operator moves the nozzle along the wall direction, the scraper can move along with the first mounting seat and level the sprayed waterproof coating. The cross groove can help the operator adjust the distance between the scraper and the waterproof coating, facilitating the adjustment of the thickness of the waterproof coating.

[0028] Preferably, the second driving assembly includes a worm wheel and a worm. The worm is arranged at the hinge joint of the first mounting seat and the second mounting seat. The worm wheel is fixedly sleeved on the rotating shaft. The worm wheel is meshed with the worm.

[0029] By adopting the above technical solution, when the operator rotates the first mounting seat or the second mounting seat to change its working position, when the first mounting seat or the second mounting seat rotates around the hinge point, the worm rotates simultaneously. The rotation of the worm causes the worm wheel to rotate. The rotation of the worm wheel causes the rotating shaft to rotate. The rotation of the rotating shaft causes the scraper to rotate. Thus, when the scraper levels the waterproof coating on the wall or the joint of the pipeline, the scraper can always remain perpendicular to the wall or tangent to the pipeline.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. By arranging the first mounting seat and the second mounting seat, the waterproof coating can be sprayed at the corner of the wall and the joint of the pipeline, avoiding the unevenness of the waterproof coating caused by manual errors and affecting the waterproof effect;

[0032] 2. By setting the buffer spring, the buffer spring can maintain the frictional force when the driving wheel contacts the pipeline. When the driving wheel rotates and causes the first mounting seat and the second mounting seat to rotate around the pipeline, the buffer spring can avoid slipping.

[0033] 3. By setting the scraper, the scraper can move along with the first mounting seat and level the waterproof coating after spraying, ensuring the flatness of the waterproof coating and improving the construction quality. Description of the Drawings

When the operator sprays the waterproof coating at the pipe joint, the operator unfolds the first mounting seat 1 and the second mounting seat 2, and sleighs the first mounting seat 1 and the second mounting seat 2 on the pipe. The angle of the nozzle 11 is adjusted so that the nozzle 11 faces the pipe joint, and the first mounting seat 1 and the second mounting seat 2 are moved so that the nozzle 11 faces the pipe joint. The nozzle 11 is started, and the first mounting seat 1 and the second mounting seat 2 are rotated so that the first mounting seat 1 and the second mounting seat 2 rotate around the pipe. At this time, the waterproof coating sprayed by the nozzle 11 can be evenly laid on the pipe joint.
