Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and more specifically, relates to a foaming adhesive injection and sealing device and its usage method. Background Technology

[0002] In the field of building door and window installation, sealing the gaps between the window frame and the wall is one of the core procedures in door and window installation. It directly determines the installation stability, thermal insulation performance, sound insulation effect, and waterproof and seepage prevention capabilities of the doors and windows. It is also a key control point for preventing leakage and energy-saving construction in building projects. Currently, the industry-standard construction process is to inject polyurethane foam into the gap between the window frame and the wall directly through a caulking machine after the window frame is fixed in place. The expansion property of the foam during curing fills the gap. After the foam has fully cured, the excess foam that has overflowed to the outside of the gap is manually trimmed. Finally, sealant is used to complete the surface sealing treatment. This construction method is widely used in door and window installation projects of various civil and industrial buildings due to its convenient operation and strong adaptability.

[0003] However, in long-term practical construction applications, the traditional open-type direct injection method has fundamental technical defects. First, the traditional construction method lacks a restrained sealing structure. During the injection and curing expansion of the foam, there is no external constraint. Most of the adhesive overflows to the outside of the gap under the pressure, with only a small amount remaining inside. The overflowing adhesive occupies a large portion of the foam expansion margin, resulting in insufficient adhesive filling and uneven compression density inside the gap, easily leading to problems such as internal cavities, incomplete filling, and local voids. Second, the industry-standard post-treatment process of "cutting the overflowing adhesive after curing" further exacerbates filling defects. Manually cutting the overflowing adhesive only removes excess foam on the surface and cannot compensate for the problem of insufficient filling and density inside the gap. At the same time, the cutting process easily disturbs the structure of the cured foam, causing the internal adhesive to loosen and crack, thus compromising the overall sealing integrity. This makes it impossible to standardize the control of the density and uniformity of the sealing layer between the window frame and the wall, which greatly reduces the stability of the connection between the door / window and the wall.

[0004] Based on the above-mentioned technical problems, the applicant of this application requests the design of a foam injection sealing device and its usage method. Summary of the Invention

[0005] The purpose of this invention is to provide a foam injection sealing device and its usage method to solve the technical problems of excessive foam overflow, incomplete filling of gaps, and easy disturbance of the colloid structure when cutting after curing in the traditional open direct injection construction method, which leads to the inability to standardize and control the density and uniformity of the sealing layer, and the decline in the stability and sealing performance of door and window installation.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, a foam injection sealing device is provided, comprising: Clamping assembly; The clamping plate assembly is movably installed at the end of the clamping handle assembly via an adjustment mechanism, and is clamped by the clamping handle assembly, thereby clamping the clamping plate assembly to the window frame and abutting against the wall. The clamping plate assembly includes: The first clamping plate is installed at one end of the clamping handle assembly to abut against one side of the window frame; The second clamping plate is installed at the other end of the clamping handle assembly to abut against the other side of the window frame. The first clamping plate is arranged opposite to the first clamping plate to surround the filling gap between the window frame and the wall.

[0007] In one possible implementation, based on the above technical solutions, the second clamping plate is provided with a sealing mechanism to promptly seal the foam after it is injected through the second clamping plate. The sealing mechanism includes a sealing plate and a push handle. The second clamping plate has a placement groove on the side facing the first clamping plate. The sealing plate is hinged in the placement groove. The groove wall of the placement groove has a push arc opening. The push handle passes through the push arc opening and is fixedly connected to the sealing plate to manually drive the sealing plate to rotate around the hinge point, thereby achieving the sealing of the foam.

[0008] In one possible implementation, based on the above technical solutions, the end of the second clamping plate is provided with a first protrusion plate, and the closing plate is provided with a second protrusion plate at the corresponding position of the first protrusion plate. The second protrusion plate is provided with a hinge shaft, and the closing plate is hinged to the second clamping plate through the hinge shaft.

[0009] In one possible implementation, based on the above technical solutions, the clamping handle assembly includes a first handle and a second handle. The first handle and the second handle have the same structure. The first handle includes a grip section and a bending section, which are integrally formed. A rotation notch is provided on the bending section. The first handle and the second handle are hinged to each other through the rotation notch, thereby enabling them to rotate relative to each other.

[0010] In one possible implementation, based on the above technical solutions, an installation notch is further provided on the bent section. The adjustment mechanism is installed within the installation notch. The adjustment mechanism includes a first telescopic member, a moving block, and a first top spring. Guide grooves are connected to the upper and lower sidewalls of the installation notch. The moving block is adapted to the guide grooves and is inserted into them. A column is provided on the moving block, and a column groove is provided on the sidewall of the installation notch opposite to the column. The first top spring is sleeved around the column, and the end of the column is inserted into the column groove. A fastening hole is provided on the moving block. The first and second clamping plates are formed with connecting blocks, and the connecting blocks are provided with inserts. The connecting blocks are placed in the mounting notch, and the inserts penetrate the fastening holes, thereby adapting to and replacing the first and second clamping plates of different specifications. The first telescopic device is fixed to one side of the mounting notch by a fixing plate and closes the mounting notch. The output end of the first telescopic device abuts against the connecting block. By controlling the first telescopic device, the positions of the first and second clamping plates on the first handle and the second handle, respectively, can be adjusted, thereby adapting to window frames of different thicknesses.

[0011] In one possible implementation, based on the above technical solutions, a first force-applying mechanism is provided between the grip section of the first handle and the grip section of the second handle. The first force-applying mechanism includes a first cylinder, a second cylinder, and a second top spring. The first cylinder is fixed to the grip section of the first handle, and the second cylinder is fixed to the grip section of the second handle. The first cylinder and the second cylinder are sleeved together. The second top spring is placed inside the first cylinder and the second cylinder to provide an initial clamping force to the first clamping plate and the second clamping plate.

[0012] In one possible implementation, in conjunction with the above technical solution, a second force-applying mechanism is provided between the grip section of the first handle and the grip section of the second handle. The second force-applying mechanism includes two threaded top blocks and a turning block. The threaded top block includes a force-applying block and a threaded post. The threaded post and the force-applying block are integrally formed. The turning block has a bidirectional threaded groove. The two ends of the bidirectional threaded groove are respectively threadedly connected to the two threaded posts. By turning the turning block, the two threaded top blocks can be brought close together or separated. The grip sections of the first handle and the grip sections of the second handle have force-applying grooves at their ends, and the two force-applying blocks are inserted into the force-applying grooves.

[0013] In one possible implementation, based on the above technical solutions, the placement slot is further provided with an auxiliary mechanism, which includes a second telescopic device. An insertion hole is formed on the wall of the placement slot, and the second telescopic device is placed inside the insertion hole. A switch is provided in the middle of the push handle to control the second telescopic device, and the output end of the second telescopic device abuts against the side wall of the sealing plate. A first hanging ring is formed on the wall of the placement slot, and a second hanging ring is formed on the side wall of the sealing plate. Elastic ropes are connected to the first and second hanging rings to pull the sealing plate to maintain its tilted state.

[0014] In one possible implementation, based on the above technical solutions, polyethylene layers are adhered to the opposite sides of both the first clamping plate and the closing plate.

[0015] Secondly, a method for using a foam injection sealing device is provided, comprising the following steps: S1, control the extension and retraction of the first telescopic device, push the connecting block and the moving block to slide along the guide groove, adjust the extension length of the first clamping plate and the second clamping plate so that the device can adapt to the thickness of the window frame; pinch the grip section of the first handle and the grip section of the second handle in opposite directions to open the first clamping plate and the second clamping plate. S2, surround the area where expanding foam needs to be injected with the opened first and second clamps, and then release your hands so that the first clamp and the sealing plate are initially fixed to the window frame. At this time, the sealing plate is in an inclined state and a gap is left between it and the wall. S3, inject expanding foam into the gap between the sealing plate and the wall from bottom to top. While injecting the expanding foam, hold the push handle by hand and rotate it along the push arc to slowly close the seal and prevent the expanding foam from overflowing. During this process, press the switch to assist in completing the closing work through the second telescopic device. S4, insert the two force blocks into the force slot and twist the twisting block to separate the two force blocks, thereby making the first clamping plate and the closing plate clamp the window frame more firmly; S5. After the expanding foam has solidified, remove the two force blocks, pinch the grip sections of the first handle and the second handle in opposite directions, and remove the entire expanding foam injection sealing device.

[0016] The beneficial effects of the expanding foam injection sealing device provided by this invention are as follows: Compared with the prior art, the expanding foam injection sealing device provided by this invention, by using a clamping handle assembly to drive a clamping plate assembly to clamp onto the window frame, forms a surrounding constraint on the filling gap between the window frame and the wall. During the injection process, it restricts the expanding foam from overflowing outwards, forcing the expanding foam to fully expand and fill the gap. This effectively solves the problem of insufficient internal filling and cavities caused by the overflow of the foam in traditional construction, and significantly improves the density and uniformity of the sealing layer. By setting a closing mechanism on the second clamping plate, the injection port can be closed simultaneously during the injection process, achieving simultaneous injection and sealing to prevent the expanding foam from overflowing. At the same time, it avoids the process of manually cutting the overflowing foam after curing, eliminating the disturbance of the cured foam structure during the cutting process and ensuring the integrity of the sealing layer. The adjusting mechanism can adjust the position of the first and second clamping plates on the clamping handle assembly to accommodate window frames of different thicknesses, expanding the applicability of the device. The first force-applying mechanism provides initial clamping force, while the second force-applying mechanism further enhances the clamping tightness, ensuring that the device will not shift during the adhesive injection process and guaranteeing the stability of the sealing effect. The auxiliary mechanism assists in closing the sealing plate through the second telescopic device, reducing the intensity of manual operation. The elastic rope can pull the sealing plate to maintain an inclined state, facilitating the adhesive injection operation. The polyethylene layer adhered to the first clamping plate and the sealing plate prevents the foam adhesive from sticking to the device, facilitating the reuse of the device.

[0017] The beneficial effects of the method of using the foaming adhesive injection sealing device provided by the present invention are as follows: the operation process is simple and standardized, which can realize standardized construction, effectively improve the construction efficiency and quality of sealing gaps in doors and windows, and ensure the installation firmness, thermal insulation performance and waterproof and seepage prevention capabilities of doors and windows.

In the description of this invention, "a plurality of" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0027] The present invention will now describe a foaming adhesive injection and sealing device.

[0028] like Figures 1 to 7 As shown, the expanding foam injection sealing device provided in this embodiment of the invention includes a clamping handle assembly 100 and a clamping plate assembly 200. The clamping plate assembly 200 is movably installed at the end of the clamping handle assembly 100 via an adjusting mechanism 300. The clamping handle assembly 100 is used to apply clamping force to the clamping plate assembly 200, so that the clamping plate assembly 200 is firmly clamped on the window frame and abuts against the wall surface, thereby forming a surrounding constraint on the filling gap between the window frame and the wall, preventing the expanding foam from overflowing to the outside during the injection and curing expansion process.

[0029] The clamping plate assembly 200 includes a first clamping plate 210 and a second clamping plate 220 arranged opposite to each other. The first clamping plate 210 is installed at one end of the clamping handle assembly 100 and is used to abut against one side surface of the window frame. The second clamping plate 220 is installed at the other end of the clamping handle assembly 100 and is used to abut against the other side surface of the window frame. The first clamping plate 210 and the second clamping plate 220 cooperate to completely surround the filling gap between the window frame and the wall, forming a relatively closed glue injection space.

[0030] Furthermore, such as Figure 2 , Figure 4 and Figure 5 As shown, the second clamping plate 220 is provided with a sealing mechanism 400, which is used to simultaneously seal the injection port during the glue injection process to prevent the foaming glue from overflowing. The sealing mechanism 400 includes a sealing plate 410 and a push handle 420. The second clamping plate 220 has a placement groove 221 on the side facing the first clamping plate 210. The sealing plate 410 is hinged in the placement groove 221. The groove wall of the placement groove 221 has a through push arc 222. The push handle 420 passes through the push arc 222 and is fixedly connected to the sealing plate 410. By manually pushing the push handle 420 to slide along the push arc 222, the sealing plate 410 can be rotated around the hinge point to realize the opening and closing of the glue injection port.

[0031] Specifically, such as Figure 4 and Figure 5 As shown, the end of the second clamping plate 220 is provided with a first protruding plate 223, and the closing plate 410 is provided with a second protruding plate 411 at the position corresponding to the first protruding plate 223. The second protruding plate 411 is provided with a hinge shaft 412, and the closing plate 410 is hinged to the second clamping plate 220 through the hinge shaft 412.

[0032] like Figure 2As shown, the clamping handle assembly 100 includes a first handle 110 and a second handle 120 with identical structures. Both the first handle 110 and the second handle 120 include an integrally formed grip section 111 and a bending section 112. The bending section 112 has a rotation notch 113. The first handle 110 and the second handle 120 are hinged to each other through their rotation notches 113 to form a scissor-like structure. By pinching the two grip sections 111, the two bending sections 112 can be opened or closed, thereby causing the first clamping plate 210 and the second clamping plate 220 to open or clamp.

[0033] like Figure 5 and Figure 6 As shown, the adjustment mechanism 300 is installed in the mounting notch 114 on the bent section 112 to adjust the position of the first clamping plate 210 and the second clamping plate 220 on the clamping handle assembly 100 to adapt to window frames of different thicknesses. The adjustment mechanism 300 includes a first telescopic member 310, a moving block 320, and a first top spring 330. The upper and lower side walls of the mounting notch 114 are connected by guide grooves 115. The moving block 320 is adapted to the guide groove 115 and inserted into the guide groove 115, and can slide along the guide groove 115. A column 116 is provided inside the moving block 320. A column groove 117 is opened on the side wall of the mounting notch 114 opposite to the column 116. The first top spring 330 is sleeved around the column 116, and the end of the column 116 is inserted into the column groove 117 to apply a restoring spring force to the moving block 320. The first clamping plate 210 and the second clamping plate 220 are provided with fastening holes 321. Connecting blocks 211 are formed on both the first clamping plate 210 and the second clamping plate 220. The connecting blocks 211 are provided with inserts 212. The connecting blocks 211 are placed in the mounting notch 114 and the inserts 212 penetrate the fastening holes 321, so as to realize the detachable connection between the first clamping plate 210, the second clamping plate 220 and the moving block 320, which is convenient for replacing clamping plates of different specifications. The first expansion joint 310 is fixed to one side of the mounting notch 114 by a fixing plate and the mounting notch 114 is closed. The output end of the first expansion joint 310 abuts against the connecting block 211. By controlling the extension and retraction of the first expansion joint 310, the connecting block 211 and the moving block 320 can be pushed to slide along the guide groove 115, thereby adjusting the width between the first clamping plate 210 and the second clamping plate 220 to adapt to window frames of different thicknesses.

[0034] like Figure 1 and Figure 2As shown, a first force-applying mechanism 500 is provided between the grip section 111 of the first handle 110 and the grip section 111 of the second handle 120, for providing initial clamping force to the first clamping plate 210 and the second clamping plate 220. The first force-applying mechanism 500 includes a first cylinder 510, a second cylinder 520 and a second top spring. The first cylinder 510 is fixed on the grip section 111 of the first handle 110, and the second cylinder 520 is fixed on the grip section 111 of the second handle 120. The second top spring is placed inside the first cylinder 510 and the second cylinder 520, and its two ends abut against the bottom of the first cylinder 510 and the second cylinder 520 respectively. In the natural state, the elastic force of the second top spring will push the two grip sections 111 away from each other, thereby keeping the first clamping plate 210 and the second clamping plate 220 in a clamping state.

[0035] Furthermore, such as Figure 3 and Figure 7 As shown, a second force-applying mechanism 600 is also provided between the end of the grip section 111 of the first handle 110 and the second handle 120 to further enhance the clamping tightness and prevent the device from shifting during the glue injection process. The second force-applying mechanism 600 includes two threaded top blocks 610 and a screwing block 620. The threaded top block 610 includes an integrally formed force-applying block 611 and a threaded post 612. The screwing block 620 has a bidirectional threaded groove 621, and the two ends of the bidirectional threaded groove 621 are respectively threadedly connected to the two threaded posts 612; the first handle Both the handle 110 and the second handle 120 have a force groove 118 at the end of the grip section 111. Two force blocks 611 are respectively inserted into the two force grooves 118. By turning the turning block 620, the two threaded posts 612 can move towards each other or away from each other along the bidirectional threaded groove 621. When the two threaded posts 612 move away from each other, the two force blocks 611 will press against the inner wall of the two force grooves 118 respectively, thereby further distancing the two grip sections 111 from each other and enhancing the clamping force of the first clamping plate 210 and the second clamping plate 220.

[0036] like Figure 4As shown, the placement groove 221 is also provided with an auxiliary mechanism 700 to assist in closing the sealing plate 410 and reduce the intensity of manual operation. The auxiliary mechanism 700 includes a second telescopic device 710 and an elastic rope 720. An insertion hole 224 is provided on the groove wall of the placement groove 221. The second telescopic device 710 is placed in the insertion hole 224. A switch 421 is provided in the middle of the push handle 420. The switch 421 is electrically connected to the second telescopic device 710 and is used to control the extension and retraction of the second telescopic device 710. The output end of the second telescopic device 710 abuts against the side wall of the sealing plate 410. A first hanging ring 225 is formed on the groove wall of the placement groove 221 and a second hanging ring 413 is formed on the side wall of the sealing plate 410. The two ends of the elastic rope 720 are respectively connected to the first hanging ring 225 and the second hanging ring 413, and are used to pull the sealing plate 410 to keep it in an inclined state, so that a gap for glue injection is formed between the sealing plate 410 and the wall, which facilitates the glue injection operation. When the push handle 420 is pushed by hand to close the sealing plate 410, the switch 421 is pressed at the same time to activate the second telescopic device 710. The output end of the second telescopic device 710 extends out to assist in pushing the sealing plate 410 to rotate, thereby achieving the assisted closing of the sealing plate 410.

[0037] Preferably, polyethylene layers are adhered to the opposite sides of the first clamping plate 210 and the sealing plate 410. The polyethylene layers have the property of not sticking to the foam, which can prevent the foam from sticking to the device after curing, and facilitate the cleaning and reuse of the device.

[0038] Based on the same inventive concept, this application also provides a method for using the expanding foam injection sealing device, which includes the following steps: S1, according to the thickness of the window frame to be constructed, pre-adjust the adjustment mechanism 300: control the extension and retraction of the first expansion joint 310, push the connecting block 211 and the moving block 320 to slide along the guide groove 115, adjust the extension length of the first clamping plate 210 and the second clamping plate 220 so that the device can adapt to the thickness of the window frame; then pinch the grip section 111 of the first handle 110 and the second handle 120 with your hands to overcome the elasticity of the second top spring, so that the first clamping plate 210 and the second clamping plate 220 open. S2, align the opened first clamp 210 and second clamp 220 with the filling gap between the window frame and the wall, then release your hand. Under the elastic force of the second top spring, the first clamp 210 and the sealing plate 410 are initially clamped and fixed on the window frame. At this time, under the tension of the elastic rope 720, the sealing plate 410 remains in an inclined state, forming a glue injection gap with the wall. S3, insert the nozzle of the expanding foam gun into the glue injection gap between the sealing plate 410 and the wall, and slowly inject expanding foam from bottom to top; during the injection process, hold the push handle 420 and let it slide slowly upward along the push arc 222, causing the sealing plate 410 to rotate around the hinge axis 412 and gradually close the glue injection port; at the same time, you can press the switch 421 on the push handle 420 to activate the second telescopic device 710 to assist in pushing the sealing plate 410 to close, preventing expanding foam from overflowing from the glue injection port; S4. After the glue is injected, insert the two force blocks 611 of the second force mechanism 600 into the force grooves 118 at the ends of the first handle 110 and the second handle 120 respectively. Then, turn the turning block 620 to make the two threaded top blocks 610 move apart, further tighten the two grip sections 111, enhance the clamping force of the first clamping plate 210 and the second clamping plate 220, and ensure that the device will not shift during the curing and expansion of the foam. S5. After the foam has fully cured, twist the twisting block 620 in the opposite direction to make the two threaded top blocks 610 move towards each other and release the second force-giving mechanism 600. Then, pinch the grip section 111 of the first handle 110 and the second handle 120 to open the first clamping plate 210 and the second clamping plate 220. Remove the device to complete the sealing of the gap between the window frame and the wall.

[0039] The method of using the foaming adhesive injection sealing device provided by this invention is simple and standardized, enabling standardized construction and effectively improving the construction efficiency and quality of sealing gaps in doors and windows, thus ensuring the installation firmness, thermal insulation performance, and waterproof and seepage-proof capabilities of doors and windows.
