Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, and more specifically to a sealing and waterproofing device for prefabricated buildings. Background Technology

[0002] Buildings assembled on-site from prefabricated components are called prefabricated buildings. According to the form of prefabricated components and construction methods, they are divided into five types: block buildings, panel buildings, box buildings, frame panel buildings and lift-slab lift-story buildings. During the construction of prefabricated buildings, it is often necessary to fill polyurethane sealant with glue gun and treat the joints to ensure the sealing and waterproofing of the joints of the prefabricated buildings. Currently, after prefabricated buildings are assembled, sealant needs to be applied to the joints to increase their sealing and waterproofing properties. Existing methods typically use a caulking gun, which requires manual pressing to squeeze the sealant out and seal the joints. Uneven pressure during pressing easily leads to uneven sealant application, reducing the building's sealing performance. Therefore, we propose a sealing and waterproofing device for prefabricated buildings. Summary of the Invention

When the arc plate moves upward, the elliptical plate slides on the surface of the bent tube, sealing the bent tube and preventing glue from leaking out when flowing inside the bent tube.

[0008] Furthermore, the pressing component includes a protruding plate, a fixing frame, a bent plate, and an air bladder. The protruding plate is fixedly connected to the surface of the pressure plate, the fixing frame is fixedly connected to the surface of the cylindrical tube, and the air bladder is fixedly connected to the bottom of the fixing frame. Two fixing frames are provided on the surface of the cylindrical tube, and air bladders are fixedly connected to the bottom of the two fixing frames respectively. The right side of the bent plate is fixedly connected to the inner wall of the feeding tube, so that the gas inside the air bladder flows into the storage tank through the bent plate when it enters the inside of the feeding tube. A one-way valve is provided on the surface of the air bladder, so that when the air bladder expands, it can draw out the outside air through the one-way valve. The air bladder is connected to the inside of the feeding tube, and the bent plate is fixedly connected to the inner wall of the feeding tube.

[0009] Furthermore, the end of the protruding plate contacts the surface of the fixing frame, and the right side of the bent plate is fixedly connected to the inner wall of the feed pipe.

[0010] Furthermore, the sealing component includes an arc-shaped spring sheet, an expansion plate, a positioning frame, a sealing block, and a connecting rod. The bottom of the arc-shaped spring sheet is fixedly connected to the expansion plate, and the right side of the expansion plate is fixedly connected to the surface of the glue gun tube. There are three arc-shaped spring sheets and two expansion plates, with the two plates located at the bottom left and right ends of the arc-shaped spring sheet.

The scraper is in contact with the surface of the roller.

[0012] The beneficial effects of this invention are as follows: In this invention, the adhesive is added to the cylindrical tube through the feed pipe. The adhesive inside the cylindrical tube then enters the storage tank through the discharge pipe. The adhesive then enters the glue gun tube for storage. After the glue gun tube is full, the bend is sealed by the discharge component, allowing excess adhesive to be stored in the storage tank, increasing the glue gun tube's storage capacity. The pressure plate, through the retraction of the electric push rod, pushes the scale rod downwards in the glue gun tube. The extrusion block discharges the adhesive from the dispensing tube through the scale rod, eliminating the need for manual pressing. The adhesive can be applied to the joints of prefabricated buildings for sealing. The sealing component seals the dispensing tube, preventing adhesive leakage when the glue gun tube is not in use.

[0013] When the glue inside the glue gun tube is used up, the scale rod pulls the extrusion block upward via the electric push rod. The push rod, through the extrusion block, pushes the connecting plate upward. The pressure rod, through the connecting plate, pulls the arc plate upward, causing the block to separate from the inner wall of the bend tube. This allows the glue from the storage tank to be added into the glue gun tube, increasing the glue storage capacity of the glue gun tube and improving its utilization efficiency. When the extrusion block separates from the bottom of the push rod, the connecting plate, through the elasticity of the spring, squeezes the block into the bend tube, sealing the bend tube.

[0014] When the pressure plate of this invention moves downward, the protruding plate compresses the air bladder by the downward movement of the pressure plate, causing it to contract. After the gas inside the air bladder enters the interior of the feeding pipe, it increases the air pressure inside the feeding pipe. The protruding plate continuously compresses the air bladder, causing the air bladder to continuously compress the interior of the feeding pipe. When the pressure inside the feeding pipe increases, the flow rate of the glue between the feeding pipe and the storage tank increases.

[0015] When the roller of this invention comes into contact with the wall, the roller frame will push the positioning frame to rotate on the surface of the glue dispensing tube by squeezing. When the positioning frame rotates, it will pull the sealing block to move to the outer end of the glue dispensing tube through the linkage rod. When the pressure on the roller frame increases, the positioning frame will push the sealing block to separate from the glue dispensing tube through the pressure of the roller frame, so as to adjust the amount of glue flowing out by adjusting the separation distance between the sealing block and the glue dispensing tube.

[0016] In this invention, the roller moves along with the glue gun tube via a roller frame. When the glue tube applies glue to the joints of prefabricated buildings, the roller squeezes and spreads the glue through the movement of the glue gun tube, preventing the glue from piling up and affecting the sealing effect. The surface of the roller is cleaned by a scraper, thereby improving the working efficiency of the roller. Attached Figure Description

The pressing component 13 is located above the glue gun tube 1. A sealing component 9 is disposed on the surface of the dispensing tube 10, with its end disposed inside the dispensing tube 10. In this invention, the adhesive is added to the cylindrical tube 6 via the feed pipe 7. The adhesive inside the cylindrical tube 6 then enters the storage tank 4 via the discharge pipe 5. The adhesive then enters the glue gun tube 1 via the storage tank 4 for storage. After the glue gun tube 1 is filled with adhesive, the bent pipe 3 is sealed by the discharge component 12, allowing excess adhesive to be stored in the storage tank 4, increasing the glue gun tube 1's storage capacity.

The extrusion block 17 discharges the adhesive from the dispensing tube 10 via the scale rod 15, allowing the adhesive to be applied to the joints of prefabricated buildings for sealing without manual pressing. The sealing component 9 seals the dispensing tube 10, preventing adhesive leakage when the glue gun tube 1 is not in use.

The block 25 is fixedly connected to the bottom of the arc plate 22. In this invention, when the glue inside the glue gun tube 1 is used up, the scale rod 15... The electric push rod 16 pulls the extrusion block 17 upward, and the push rod 27 pushes the connecting plate 20 upward through the extrusion block 17. The pressure rod 21 pulls the arc plate 22 upward through the connecting plate 20, so that the block 25 separates from the inner wall of the bend 3, so that the glue inside the storage tank 4 can be injected into the glue gun tube 1, increasing the glue storage capacity of the glue gun tube 1 and improving the utilization efficiency of the glue gun tube 1. When the extrusion block 17 separates from the bottom of the push rod 27, the connecting plate 20 uses the elasticity of the spring 26 to squeeze the block 25 into the interior of the bend 3 to seal the bend 3. The inner wall of the elliptical plate 23 is in contact with the surface of the bent pipe 3, and the groove 24 is opened at the top of the bent pipe 3.

When the pressure plate 14 moves downward, the protruding plate 30 compresses the air bladder 34 to contract. After the gas inside the air bladder 34 enters the interior of the feeding tube 5, it increases the air pressure inside the feeding tube 5. The protruding plate 30 continuously compresses the air bladder 34, so that the air bladder 34 continuously compresses the interior of the feeding tube 5. When the pressure inside the feeding tube 5 increases, the flow rate of the glue in the feeding tube 5 and the storage tank 4 increases. The protruding plate 30 is positioned on top of the pressure plate 14.

[0026] The end of the protruding plate 30 contacts the surface of the fixed frame 32, and the right side of the bent plate 33 is fixedly connected to the inner wall of the feed pipe 5.

When the positioning frame 42 rotates, it will pull the sealing block 43 to move towards the outer end of the glue dispensing tube 10 via the connecting rod 44. When the pressure on the roller frame 52 increases, the positioning frame 42 will push the sealing block 43 to separate from the glue dispensing tube 10 by the pressure of the roller frame 52, so as to adjust the amount of glue flowing out by adjusting the separation distance between the sealing block 43 and the glue dispensing tube 10. The sealing block 43 contacts the inner wall of the dispensing tube 10, and the linkage rod 44 is elastically set.

[0028] Example 2 Distinguishing features from Example 1; like Figure 7 As shown: The extrusion component 11 includes a round rod 51, a roller frame 52, a roller 53, a scraper 54, and a pressure plate 55.

The scraper 54 cleans the surface of the roller 53, thereby improving the working efficiency of the roller 53. The scraper 54 is in surface contact with the roller 53.

[0029] One specific application of this embodiment is as follows: After the glue is added into the cylindrical tube 6 through the feed pipe 7, the glue inside the cylindrical tube 6 enters the storage tank 4 through the discharge pipe 5. The glue then enters the glue gun tube 1 through the storage tank 4 for storage. After the glue gun tube 1 is filled with glue, the bend 3 is sealed by the discharge component 12, so that excess glue can be stored inside the storage tank 4, thereby increasing the glue storage capacity of the glue gun tube 1. The pressure plate 14... The electric actuator 16 retracts, pushing the scale rod 15 downwards towards the glue gun tube 1. The extrusion block 17, via the scale rod 15, discharges glue from the inside of the glue dispensing tube 10, allowing the glue to be applied to the joints of prefabricated buildings for sealing without manual pressing. The sealing component 9 seals the glue dispensing tube 10, preventing glue leakage when the glue gun tube 1 is not in use. When the glue inside the glue gun tube 1 is used up, the scale rod 15, via the electric actuator 16, pulls the extrusion block 17 upwards. The push rod 27, through the extrusion block 17, pushes the connecting plate 20 upwards, and the pressure rod 2... 1. The connecting plate 20 pulls the arc plate 22 upward, causing the block 25 to separate from the inner wall of the bend 3, so that the glue inside the storage tank 4 can be injected into the glue gun tube 1, increasing the glue storage capacity of the glue gun tube 1 and improving the utilization efficiency of the glue gun tube 1. When the extrusion block 17 separates from the bottom of the push rod 27, the connecting plate 20, through the elasticity of the spring 26, squeezes the block 25 into the bend 3, sealing the bend 3. When the pressure plate 14 moves downward, the protruding plate 30 compresses the air bladder 34 by the downward movement of the pressure plate 14, causing it to contract, and the gas inside the air bladder 34 enters. After entering the feed pipe 5, the air pressure inside the feed pipe 5 is increased. The protruding plate 30 continuously squeezes the airbag 34, causing the airbag 34 to continuously squeeze the inside of the feed pipe 5. When the pressure inside the feed pipe 5 increases, the flow rate of the glue inside the feed pipe 5 and the storage tank 4 increases. When the roller 53 contacts the wall, the roller frame 52 will push the positioning frame 42 to rotate on the surface of the glue dispensing pipe 10 through compression. When the positioning frame 42 rotates, it pulls the sealing block 43 to move towards the outer end of the glue dispensing pipe 10 through the connecting rod 44. When the roller frame 52 is subjected to pressure When added, the positioning frame 42 pushes the sealing block 43 and the glue dispensing tube 10 apart by the pressure of the roller frame 52, so as to adjust the amount of glue flowing out by adjusting the separation distance between the sealing block 43 and the glue dispensing tube 10. The roller 53 moves with the glue gun tube 1 through the roller frame 52. When the glue dispensing tube 10 applies glue to the joints of the prefabricated building, the roller 53 squeezes and spreads the glue by the movement of the glue gun tube 1 to prevent the glue from piling up and affecting the sealing effect. The surface of the roller 53 is cleaned by the scraper 54, thereby improving the working efficiency of the roller 53.
