Description

Technical Field

[0001] The present invention relates to the field of waterproofing of assembled buildings, in particular to a method for constructing drainage pipes in prefabricated exterior walls of assembled concrete buildings. Background Art

[0002] Since prefabricated exterior walls are assembled in blocks, it is inevitable to encounter the problem of waterproofing the connecting joints, so the joints need to be waterproofed.

[0003] Some of the joints of prefabricated exterior walls of assembled buildings are directly filled with mortar, fine stone concrete or grouting materials at the joints. However, since the grouting only has slurry, it has poor adhesion to the new and old concrete surfaces. The characteristic of cement solidification is that it will lose water, and water loss will cause shrinkage. Shrinkage will cause cracks at the interface between the new and old, leaving a hidden danger of water seepage.

[0004] There is also sealing with weather-resistant sealant. This method is to set the gasket material in the joint of the prefabricated exterior wall, and set a sealant layer to form a drainage cavity. Water flows into the joint of the prefabricated exterior wall and flows downward along the foam strip. The principle of one-way drainage of the drain pipe is used to discharge the condensed water generated by the inconsistent internal and external temperatures in the drainage cavity. However, during the gluing process of this method, workers need to hold the glue outlet hose to transport glue into the joint and gradually spread the glue from the bottom of the joint upwards. Since the height of the joint extends to the top of the wall, workers need to use ladders to spread the glue. Moreover, workers cannot keep their hands stable at all times when spreading the glue, which may cause the glue to fall out of the joint. After the glue is spread, the glue surface needs to be smoothed, which makes the operation complicated. Summary of the Invention

[0041] See also Figures 1 to 10 In an embodiment of the present invention, a method for constructing a drainage pipe for a prefabricated exterior wall of an assembled concrete building comprises the following steps:

[0042] Step 1: Before construction, confirm the flatness of the wall and clean the required joints to prevent foreign matter from remaining in the gaps and causing poor waterproofing effect;

[0043] Step 2: Fill the joints with cushioning material and apply masking tape to the walls on both sides of the joints. The cushioning material at the bottom should be arranged in an inclined inverted L shape, and the cushioning material at the top should be arranged vertically. Place the drainage diversion pipe in the gap between the cushioning materials and fit it tightly against the cushioning materials.

[0044] Step 3: Mix and stir the glue to be used, place it in the gluing equipment, and use the gluing equipment to glue the joints from bottom to top. During the gluing process, the gluing equipment can also smooth the glue until the gluing is completed;

[0045] Step 4: After the glue hardens, tear off the masking tape and clean the wall.

[0046] Among them, after the masking tape is pasted, it is necessary to apply the matching primer to the joint, and start applying glue after the primer is cured. The diversion pipe is set in an L shape, with one end located in the drainage cavity formed by the lining material and the wall, and the other end located outside the wall.

[0047] See also Figures 1 to 10 , the glue spreading equipment includes:

[0048] The base 1 has a support plate 13 fixed on it, and a storage tank 38 for holding glue is also fixed on the base 1. A delivery pump 39 for pumping glue is installed on the storage tank 38, wherein the storage tank 38 is used to hold the required glue after uniform mixing. When glue needs to be applied, the delivery pump 39 works and delivers the glue in the storage tank 38 to the required position.

[0049] See also Figure 1-2 、 Figure 4-6 , a positioning mechanism is provided on the support plate 13, the positioning mechanism includes a positioning assembly and a symmetrically arranged positioning plate 21, the positioning assembly can drive the positioning plates 21 to approach or move away from each other, and in the process of moving away, the positioning plates 21 are fitted with the inner wall of the joint so that the central axis of the base 1 and the center line of the joint are in the same vertical plane, the positioning assembly includes a guide member provided on the support plate 13, and a movable sleeve 19 is movably installed on the guide member and is symmetrically arranged and fixedly connected to the positioning plate 21, and a connecting rod 15 hinged to the movable sleeve 19 is hinged on the support plate 13;

[0050] The guide member includes a guide rod 16 fixedly mounted on the support plate 13 and symmetrically arranged, a guide sleeve 17 movably mounted on the guide rod 16, a fixed rod 18 movably connected to the movable sleeve 19 fixed on the guide sleeve 17, and a No. 1 spring 20 abutting against the movable sleeve 19 is sleeved on the fixed rod 18.

[0051] It should be noted that, since the sizes of the joints produced during the installation of prefabricated panel walls are different, in order to ensure that the glue is evenly distributed, it is necessary to transport the glue from the middle of the joint to the inside of the joint. Therefore, before distributing the glue, it is necessary to adjust the position of the device. A wheel is provided at the bottom of the base 1, which can be moved to the front of the joint where the glue is required to be distributed through the wheel driving device. In the initial state, the No. 1 spring 20 is in a compressed state. Under the action of the No. 1 spring 20, the two positioning plates 21 are located at the end of the stroke close to each other and outside the joint. At this time, the No. 1 cylinder 14 works, driving the connecting rod 15 to move, and driving the movable sleeve 19 to move. The movable sleeve 19 will drive the guide sleeve 17 to move along the length direction of the guide rod 16 through the fixed rod 18. The movable sleeve 19 will also drive the positioning plate 21 to move toward the joint, and under the action of the guide rod 16, ensure that the positioning plate 21 remains stable during movement. When the positioning plate 21 contacts the filling material in the joint toward one end of the joint, the positioning plate 21 cannot continue to move toward the joint. At this time, the guide sleeve 17 stops moving, and the force applied by the connecting rod 15 on the movable sleeve 19 will drive the two movable sleeves 19 to move along the length direction of the fixed rod 18, and the two movable sleeves 19 move away from each other. When the two positioning plates 21 move to contact the wall surfaces of the two walls respectively, under the action of the positioning plates 21, the equipment will be adjusted to the desired position. At this time, the center axis of the base 1 and the center line of the joint are in the same vertical plane.

[0052] Preferably, the force exerted by the connecting rod 15 on the movable sleeve 19 can be decomposed into two directions, one is along the length direction of the positioning plate 21, and the other is along the length direction of the fixed rod 18. Since the No. 1 spring 20 is in a compressed state, under the action of the elastic force of the No. 1 spring 20, the movement of the movable sleeve 19 on the fixed rod 18 is restricted, so that when the positioning plate 21 has not moved to abut the filling material in the joint, the movable sleeve 19 can only move along the length direction of the guide rod 16.

[0053] See also Figure 1-2 、 Figure 4 、 Figure 10, a support mechanism is provided on the base 1 and is fixedly connected to the support plate 13. The support mechanism moves after the positioning mechanism is positioned and fixes the base 1. The support mechanism includes a support sleeve 2 fixedly mounted on the base 1 and symmetrically arranged. A hollow No. 1 support rod 3 is movably installed in the support sleeve 2. A No. 2 support rod 4 is movably installed in the No. 1 support rod 3. A guide rail 5 is fixed on the No. 2 support rod 4. A symmetrically arranged sliding block 11 is slidably installed on the guide rail 5. The support sleeve 2 is provided with a scissors-fork assembly connected to the sliding block 11 and is fixed with a fixed plate 12 fixedly connected to the support plate 13, wherein the scissors-fork assembly includes a handwheel 6 and a bidirectional screw rod 7 rotatably mounted on the support sleeve 2, and the bidirectional screw rod 7 is movably mounted with a symmetrically arranged threaded sleeve 8, and the two threaded sleeves 8 are respectively hinged with a No. 1 hinged rod 9 and a No. 2 hinged rod 10 that are hinged to each other, the No. 1 hinged rod 9 and the No. 2 hinged rod 10 are hinged to the sliding block 11, and the handwheel 6 is coaxially connected to the bidirectional screw rod 7.

[0054] When the cam 21 is in contact with the wall of the second frame 2, the two hinges 10 are connected, and the hinges 10 are connected in a direction that is close to each other, so that the cam 21 can be connected with the wall of the second frame 2. When the two-way screw rod 7 is engaged with the guide rail 5, the two-way screw rod 7 and the guide rail 5 are engaged with each other, and the two-way screw rod 7 and the guide rail 5 are engaged with each other, so that the two-way screw rod 7 and the guide rail 5 can move in the direction away from the base 1.

[0055] Preferably, when the No. 2 support rod 4 is in contact with the top of the wall, the No. 2 support rod 4 acts to ensure that the equipment will not shake. At this time, the protrusion fixed on the No. 1 support rod 3 has not moved to the end of the stroke where the slot is provided on the support sleeve 2, thereby ensuring that the No. 2 support rod 4 can move to the required position. After the equipment is fixed, the No. 1 cylinder 14 works again and drives the positioning plate 21 out of the joint to ensure that the positioning plate 21 will not affect the glue laying when the glue is laid.

[0056] See also Figure 1-2 、 Figure 4-5 、 Figure 7 、 Figure 9, a lifting mechanism is arranged on the support plate 13, and the lifting mechanism includes a lifting component, an elastic supporting component and a blocking plate 31. The lifting component drives the blocking plate 31 through the elastic supporting component to scrape the rubber surface of the cloth. The lifting component includes a No. 1 rotating plate 22 which is hinged on the support plate 13 and symmetrically arranged. A limit block 25 is fixed on the No. 1 rotating plate 22. A No. 2 rotating plate 23 which intermittently abuts against the limit block 25 is hinged on the No. 1 rotating plate 22. The No. 2 cylinder 24 is hinged to the No. 1 rotating plate 22, and the No. 2 rotating plate 23 is connected to the elastic support assembly, wherein the elastic support assembly includes a hinged plate 26 hinged on the No. 2 rotating plate 23, a pulley 27 is rotatably mounted on the hinged plate 26, and a symmetrically arranged fixed sleeve 28 is fixed on the hinged plate 26, a movable rod 29 fixedly connected to the blocking plate 31 is movably mounted in the fixed sleeve 28, and a No. 2 spring 30 abutting against the movable rod 29 is fixed in the fixed sleeve 28.

[0057] Furthermore, the pulleys 27 are respectively arranged at the four corners of the hinge plate 26, the fixed sleeve 28 is provided with a slide groove, and the movable rod 29 is fixed with a fixed block engaged with the slide groove to ensure that the movable rod 29 will not separate from the fixed sleeve 28. In the initial state, the No. 2 spring 30 is in a compressed state, and the movable rod 29 is located at the end of the stroke away from the fixed sleeve 28. The distance between the blocking plate 31 and the hinge plate 26 is the largest. In order to prevent the glue from separating from the joint during the gluing process, the blocking plate 31 needs to be fitted with the wall and the joint is covered. At this time, the equipment is brought close to the wall and the blocking plate 31 is fitted with the wall. In order to ensure that the blocking plate 31 is tightly against the wall The second spring 30 is compressed, and under the action of the second spring 30, it is ensured that the blocking plate 31 is tightly fitted to the wall. In the initial state, the No. 2 rotating plate 23 is in contact with the limit block 25. When glue is needed, the No. 2 cylinder 24 works and drives the No. 1 rotating plate 22 to rotate around the rotating point, thereby driving the No. 2 rotating plate 23 to move. Under the action of the pulley 27, the hinged plate 26 moves along the length direction of the seam, thereby driving the blocking plate 31 to move.

[0058] Preferably, when the No. 2 rotating plate 23 abuts against the limit block 25, under the action of the limit block 25, the No. 2 rotating plate 23 cannot continue to rotate toward the base 1, thereby ensuring that the No. 2 rotating plate 23 will not interfere with other components, and the glue can also be smoothed while the blocking plate 31 blocks the material.

[0059] See also Figure 1-5 、 Figure 8, a guide box 32 is installed on the blocking plate 31, and the guide box 32 is provided with a glue discharge pipe 37 connected to the storage tank 38 and a limiting component for limiting the position of the glue discharge pipe 37, and the limiting component includes an inclined groove 33 provided on the guide box 32, and a limiting plate 35 is slidably installed in the guide box 32. A No. 3 spring 34 that abuts against the limiting plate 35 is also fixed in the guide box 32, and a sliding plate 36 that is slidably connected to the inclined groove 33 is fixed on the glue discharge pipe 37.

[0060] Finally, the glue discharge pipe 37 can be divided into a glue discharge head and a guide tube. The glue discharge head is fixedly connected to the limit plate 35, and the glue discharge head is located above the blocking plate 31. In the initial state, the No. 3 spring 34 is in a compressed state, so that the sliding plate 36 is located at the end of the stroke on one side of the guide box 32. Under the action of the sliding plate 36, the limit plate 35 is located at the end of the stroke of the inclined groove 33. At this time, the port of the glue discharge head is located on the outside of the blocking plate 31 away from the hinged plate 26. When the blocking plate 31 is in contact with the wall, the glue discharge head slightly enters the joint to ensure that the glue can completely enter the joint after being discharged through the glue discharge head. At this time, the delivery pump 39 works and delivers the glue in the storage tank 38 into the joint through the glue discharge pipe 37. At the same time, under the action of the No. 2 cylinder 24, the hinged plate 26 rises slowly, and drives the blocking plate 31 to rise slowly, thereby ensuring that the joint is filled with glue. When the glue discharging head moves to the highest point of the joint, in order to ensure that the glue at the top of the joint is also smoothed, it is necessary to make the glue discharging head detach from the joint and move between the hinge plate 26 and the blocking plate 31. Since the glue discharging head has abutted against the wall top, the blocking plate 31 continues to move toward the wall top position and drives the guide box 32 to move, thereby driving the inclined slot 33 to move. Since the inclined slot 33 is engaged with the sliding plate 36, under the action of the inclined slot 33, the sliding plate 36 slides along the inclined slot 33, thereby driving the glue discharging head to move in the direction away from the joint, and the sliding plate 36 will also drive the limit plate 35 to move, causing the No. 3 spring 34 to be compressed again. When the glue discharging head detaches from the joint, the glue injection is completed and the delivery pump 39 stops working. When the glue discharging head moves between the hinge plate 26 and the blocking plate 31, the blocking plate 31 moves to the same height as the glue discharging head and smoothes the glue applied to the top joint.

[0061] Preferably, during the glue injection process, in order to ensure that the glue does not separate from the joints, the blocking plate 31 cannot be separated from the glue before the glue dries. Therefore, the rising distance of the blocking plate 31 each time cannot be greater than the length of the blocking plate 31, and it continues to rise after staying for a certain period of time.

[0062] Taking the embodiment combining all the features described in this application as an example, when in use, since the sizes of the joints produced by the prefabricated panel wall are different during installation, in order to ensure that the glue is evenly distributed, the glue outlet pipe 37 needs to be located in the middle of the joint to ensure that the glue is transported from the middle of the joint to the inside of the joint. Therefore, before spreading the glue, the position of the device needs to be adjusted. At this time, the wheel drives the device to move to the front of the joint where the glue is required to be distributed, and the blocking plate 31 is fitted with the wall. In order to ensure that the blocking plate 31 is tightly fitted with the wall and that the hinge plate 26 is in a position parallel to the wall, the device needs to continue to approach the wall until the pulley 27 is fitted with the wall, the distance between the blocking plate 31 and the hinge plate 26 is reduced, and the No. 2 spring 30 is compressed. Under the action of the No. 2 spring 30, the blocking plate 31 is ensured. The material plate 31 fits tightly against the wall. In the initial state, the No. 1 spring 20 is in a compressed state. Under the action of the No. 1 spring 20, the two positioning plates 21 are at the end of the stroke close to each other and outside the joint. At this time, the No. 1 cylinder 14 works, driving the connecting rod 15 to move, and driving the movable sleeve 19 to move. The movable sleeve 19 will drive the guide sleeve 17 to move along the length direction of the guide rod 16 through the fixed rod 18. The movable sleeve 19 will also drive the positioning plate 21 to move toward the inside of the joint, and under the action of the guide rod 16, ensure that the positioning plate 21 remains stable during movement. When one end of the positioning plate 21 toward the joint contacts the filling material in the joint, the positioning plate 21 cannot continue to move toward the inside of the joint. At this time, the guide sleeve 17 stops moving, and the connecting rod 15 exerts pressure. The force applied to the movable sleeve 19 will drive the two movable sleeves 19 to move along the length direction of the fixed rod 18, and the two movable sleeves 19 will move away from each other. When the two positioning plates 21 move respectively to abut the wall surfaces of the two walls, the equipment will be adjusted to the required position under the action of the positioning plates 21. At this time, the central axis of the base 1 and the center line of the joint are in the same vertical plane. At the same time, the equipment needs to be fixed, and the handwheel 6 is rotated by manpower to drive the bidirectional screw rod 7 to rotate, thereby driving the threaded sleeve 8 to move in the direction of approaching each other. The threaded sleeve 8 will drive the No. 1 hinged rod 9 and the No. 2 hinged rod 10 to move, so that the sliding block 11 moves along the length direction of the guide rail 5, and drives the guide rail 5 to move in the direction away from the base 1, and the two sliding blocks When the second support rod 1 is in contact with the wall, the first support rod 3 is moved to the left of the support rod 1 and the second support rod 1 is moved to the right of the support rod 1. When the second support rod 1 is in contact with the wall, the first support rod 3 is moved to the right of the support rod 1 and the second support rod 1 is moved to the left of the support rod 1. When the second support rod 1 is in contact with the wall, the first support rod 3 is moved to the right of the support rod 1 and the second support rod 1 is moved to the right of the support rod 1.At the same time, the second cylinder 24 works and drives the first rotating plate 22 to rotate around the rotating point, thereby driving the second rotating plate 23 to move. Under the action of the pulley 27, the hinged plate 26 moves along the length direction of the joint, thereby driving the blocking plate 31 to move. When the glue head moves to the highest point of the joint, since the glue head has abutted against the top of the wall, the blocking plate 31 continues to move toward the top of the wall and drives the guide box 32 to move, thereby driving the inclined slot 33 to move. Since the inclined slot 33 and the sliding plate 3 6 is engaged. Under the action of the inclined groove 33, the sliding plate 36 slides along the inclined groove 33, thereby driving the glue head to move away from the joint. The sliding plate 36 also drives the limit plate 35 to move, causing the third spring 34 to be compressed again. When the glue head is out of the joint, the glue injection is completed and the delivery pump 39 stops working. When the glue head moves to between the hinge plate 26 and the blocking plate 31, the blocking plate 31 moves to the same height as the glue head and smoothes the glue applied to the top joint.
