Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a waterproofing construction device for prefabricated exterior wall joints. Background Technology

[0002] In recent years, with the rapid development of prefabricated buildings in my country, prefabricated exterior wall panels (beam bottom slabs) have been increasingly widely used in public buildings. In order to ensure the waterproofing effect of the building's exterior walls, more and more composite beams are adopting waterproofing construction measures with inverted retaining walls and tongue-and-groove joints.

[0003] In existing technologies, when performing sealing and waterproofing construction on the exterior wall joints of prefabricated buildings, the general method is to manually spray the sealing and waterproofing adhesive onto the joints using a handheld caulking gun, and then manually scrape off the excess adhesive. This manual spraying and scraping of adhesive results in high labor intensity for workers, and the lack of complete repeatability and consistency in manual operation easily leads to uneven adhesive spraying.

[0004] Therefore, it is necessary to provide a new waterproofing construction device for prefabricated exterior wall joints to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a prefabricated exterior wall joint waterproofing construction device that can enhance the construction efficiency of exterior wall joint sealing and waterproofing and improve the adhesion performance between the sealant and the substrate.

[0006] To solve the above-mentioned technical problems, the present invention provides a waterproofing construction device for precast exterior wall joints, comprising: a telescopic rod, one end of which is rotatably connected to the back of the main structure; rollers are rotatably connected to the side walls at both ends of the main structure, and the rollers abut against the side walls of the precast wall; a connecting pipe is provided on the back of the outer shell, one end of which is slidably connected to a spray head through the outer shell, and one end of the spray head is supported by a spring inside the outer shell; an inner cavity is provided on each side of the outer shell, and a groove is provided on the inner side wall of the inner cavity; and an adhesive structure, which is installed in the inner cavities on both sides of the outer shell. The adhesive structure includes a retaining strip, a baffle, a support rod, a dirt-proof strip, and a retaining shaft. The baffle is engaged with the edge of the back side wall of the outer shell; the retaining strip is rotatably connected to the interior of the baffle at its center; the support rod is fixedly connected to the side walls at both ends of the baffle; the retaining shaft is engaged with one end of the support rod; and the dirt-proof strip is rotatably connected to the inner side of the retaining shaft.

[0007] Preferably, the main structure includes a scraper, an alignment strip, and a slot. The scraper is fixed to the side walls at the upper and lower ends of the front of the outer shell, the alignment strip is fixed at the center of the upper scraper side wall, and the slot is located inside the opening at one end of the inner cavity.

[0008] Preferably, one end of the scraper and one end of the roller are on the same horizontal plane, and the side wall of one end of the scraper is arc-shaped and abuts against the side wall of the precast wall.

[0009] Preferably, there are joints between the precast wall connection nodes, and the minimum diameter of one end of the spray head is smaller than the width of the joint.

[0010] Preferably, the inner wall of the alignment strip does not contact the precast wall, and its width corresponds to the width of the joint, and the alignment strip is aligned with the position of the joint.

[0011] Preferably, the card slot is arc-shaped, and the card strip engages inside the card slot.

[0012] Preferably, the support rod is provided with a spring inside, and the support rod has telescopic capability, and the retaining shaft slides inside the groove.

[0013] Compared with related technologies, the waterproofing construction device for prefabricated exterior wall joints provided by this utility model has the following beneficial effects:

[0014] This utility model provides a waterproofing construction device for precast exterior wall joints. First, the anti-fouling tape is installed at one end of the adhesive structure, which is then inserted into the interior of both sides of the outer casing. By rotating the locking strip, the strip engages with the slot, confining the adhesive structure inside the casing. Next, the telescopic rod is manipulated to abut against the joint of the precast exterior wall, and the alignment strip in the main structure is used to align the device with the joint. One end of the spray pipe is then inserted into the joint, and a waterproofing adhesive spraying cylinder is connected to the other end of the spray pipe to apply the waterproofing adhesive. Water-based adhesive can be injected into the interior of the joint through the external spray pipe. Simultaneously, by applying pressure to the telescopic rod, the anti-fouling tape adheres to the outside of the joint. As the device is slowly lowered, the anti-fouling tape adheres first because it is lower than the spray pipe, and then the waterproof adhesive is sprayed in place. During the downward movement of the device, the scraper removes excess waterproof adhesive and fills any gaps in the joint, ensuring that the interior of the joint is fully filled with waterproof adhesive. This allows the application of the anti-fouling tape, the filling of the waterproof adhesive, and the smoothing and filling of the joint to be carried out simultaneously, thereby improving the efficiency of the exterior wall joint sealing and waterproofing construction.

The groove 25 is provided on the inner side wall of the inner cavity; the adhesive structure 4 is installed in the inner cavity provided on both sides of the outer shell 21. The adhesive structure 4 includes a retaining strip 41, a baffle 42, a support rod 43, an anti-fouling strip 44, and a retaining shaft 45. The baffle 42 is engaged with the edge of the back side wall of the outer shell 21. The retaining strip 41 is rotatably connected to the inside of the baffle 42 at its center. The support rod 43 is fixedly connected to the side walls at both ends of the baffle 42. The retaining shaft 45 is engaged with one end of the support rod 43. The anti-fouling strip 44 is rotatably connected to the inside of the retaining shaft 45.

[0025] In the specific implementation process, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the main structure 2 includes a scraper 22, an alignment strip 23, and a slot 26. The scraper 22 is fixed to the side walls at both ends of the front of the outer shell 21. The alignment strip 23 is fixed at the center of the upper side wall of the scraper 22. The slot 26 is located inside the opening at one end of the inner cavity. There are joints 6 between the connecting nodes of the prefabricated wall 5, and the smallest diameter of one end of the spray head 32 is smaller than the width of the joint 6. The inner side wall of the alignment strip 23 does not contact the prefabricated wall 5, and its width corresponds to the width of the joint 6. The alignment strip 23 is aligned with the position of the joint 6; one end of the scraper 22 and one end of the roller 24 are on the same horizontal plane, and the side wall of one end of the scraper 22 is arc-shaped and abuts against the side wall of the precast wall 5; so that the outer shell 21 can abut against the side wall of the precast wall 5 through the roller 24, and the scraper 22 can also abut against the precast wall 5, and can be aligned with the position of the joint 6 through the alignment strip, so that the position of the device can be controlled when it moves.

[0026] In the specific implementation process, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the slot 26 is arc-shaped, and the clip 41 engages inside the slot 26; the support rod 43 is provided with a spring 33 inside, and the support rod 43 has telescopic capability, and the clip shaft 45 slides inside the slide groove 25; so that the clip 41 can be inserted into the slot 26, and the anti-fouling strip 44 is supported and positioned in the inner cavity on both sides of the outer shell 21 by the support rod 43, and under the support of the support rod 43, the anti-fouling strip 44 is driven to abut against the side wall of the precast wall 5 outside the joint 6.

[0027] The working principle of the waterproofing construction device for prefabricated exterior wall joints provided by this utility model is as follows:

[0028] In use, firstly, the anti-fouling tape 44 is installed on the retaining shaft 45, and the baffle 42 is secured to the side wall of the retaining shaft 45 via the support rod 43. Then, it is inserted from the back of the outer casing 21 via the baffle 42, allowing the retaining shaft 45 to slide inside the groove 25 until one end of the anti-fouling tape 44 protrudes from the front of the outer casing 21. Simultaneously, by pushing the baffle 42, the support rod 43 is compressed and retracted, causing it to rotate the retaining strip 41, which can then slide into the retaining groove 26, restricting the position of the baffle 42 and confining the anti-fouling tape 44 within the outer casing 21. Next, the outer side of the joint 6 is sanded and filled with backing material, and a primer is applied to the sanded area. Then, the construction worker holds the telescopic rod 1 and uses the rollers 24 to press the outer casing 21 against the side wall of the precast wall 5, and aligns it accordingly. The strip 23 is aligned with the joint 6 and its position is adjusted. At this time, the side wall of the anti-fouling tape 44 is in contact with the base coat material. Then, through the external glue injector connected to the connector 31, the waterproof glue can be sprayed into the joint 6 through the spray head 32 under the external connection of the connector 31. Then, by controlling the telescopic rod 1, the outer shell 21 is driven to move downward through the roller 24, and the telescopic rod 1 applies a certain force to the outer shell 21, so that the anti-fouling tape 44 is pasted on the outside of the joint 6. As the device moves downward, the anti-fouling tape 44 rotates and sticks under the support of the support rod 43. At the same time, the spray head 32 sprays the waterproof glue into the joint 6. During the downward movement of the device, the hanging plate scrapes off the excess waterproof glue and fills the joint 6, thereby achieving the purpose of waterproofing the joint 6 and improving the construction efficiency of sealing and waterproofing the external wall joint.

[0029] Compared with related technologies, the waterproofing construction device for prefabricated exterior wall joints provided by this utility model has the following beneficial effects:

[0030] This utility model provides a waterproofing construction device for precast exterior wall joints. First, the anti-fouling tape 44 is installed at one end of the adhesive structure 4, and the adhesive structure 4 is inserted into the interior of both sides of the outer casing 21. By rotating the locking strip 41, the locking strip 41 engages with the locking groove 26, confining the adhesive structure 4 inside the outer casing 21. Then, the telescopic rod 1 is manipulated to abut against the joint 6 of the precast exterior wall, and the alignment strip 23 in the main structure 2 is aligned with the joint 6, aligning the device with the joint 6. One end of the spray pipe 3 is then inserted into the joint 6, and waterproof adhesive is sprayed through the connecting pipe 31 at the other end of the spray pipe 3. The device uses a tube to inject waterproof adhesive into the joint 6 through the external spray pipe 3. Simultaneously, by applying pressure to the telescopic rod 1, the anti-fouling tape 44 is adhered to the outside of the joint 6. As the device is slowly lowered, the anti-fouling tape 44 adheres first because it is lower than the spray pipe 3, and then the waterproof adhesive is sprayed in place. During the downward movement of the device, the scraper 22 scrapes off excess waterproof adhesive and fills any gaps in the joint 6, thus ensuring that the interior of the joint 6 is fully filled with waterproof adhesive. This allows the application of the anti-fouling tape 44, the filling of the waterproof adhesive, and the smoothing and filling of the joint 6 to be carried out simultaneously, thereby improving the efficiency of the sealing and waterproofing construction of the external wall joint 6.
