Description

Technical Field

[0001] This invention relates to the field of grout-stopping tape technology, specifically a grout-stopping tape that does not require roughening. Background Technology

[0002] Grout sealant is an auxiliary component used in concrete pouring or formwork splicing during building construction. It is usually installed at formwork joints and forms a partition structure by sealing and adhering to the formwork or concrete surface. Its main function is to prevent cement grout leakage during concrete pouring, thereby ensuring the integrity and appearance quality of the concrete structure. However, existing grout sealant structures still have some shortcomings.

[0003] Patent CN106223614B discloses a formwork grout stopper, comprising an overlapping formwork and a grout stopper. The overlapping formwork is composed of a panel, main beam, support plate, and stiffening plate, connected together, and connected to the main formwork via bolt holes. The grout stopper includes a channel steel, a grout-stop hose, clamping plates, and a bidirectional screw rod. The channel steel is connected to the bidirectional screw rod, and the grout-stop hose is placed inside the channel steel. Clamping plates are installed on both sides of the channel steel to restrict the displacement of the grout-stop hose. The grout stopper is placed inside the overlapping formwork, and its relative position is adjusted by the bidirectional screw rod. A short section of overlapping formwork is connected to the bottom of the main formwork, and the grout stopper is installed inside the overlapping formwork. The grout-stop hose undergoes elastic deformation under pressure, generating deformation pressure that tightly presses against the concrete surface, forming a grout-stopping effect. This effectively solves quality problems such as grout leakage and grout dripping on the concrete surface caused by poor bonding between the formwork and the concrete surface during concrete construction. While the aforementioned grout-stopping structure can achieve the function of pressing tightly against the concrete, in use, in some wider formwork areas, after splicing multiple layers of formwork, there will be two transverse gaps. Existing technology can achieve the grout-stopping function by pasting two grout-stopping strips that stick to each other, but it cannot ensure that the two grout-stopping strips are exactly located in the gap space. If the gap is close to the edge of the grout-stopping strip, the side of the grout-stopping strip is easily lifted under the pressure of the concrete, affecting the overall sealing effect of the grout-stopping structure. The existing grout-stopping strips cannot be stably connected along their own width direction.

[0004] Patent CN106760516A discloses an elastic combined grout-stopping strip, primarily designed to address the problems of poor grout-stopping effect, limited versatility, and inconvenient construction associated with existing equipment. This elastic combined grout-stopping strip comprises a pad block, a filler block, a counter-pressure block, fastening bolts, and fastening nuts. The pad block is positioned at the bottom, the filler block is positioned on top of the pad block, and the counter-pressure block is positioned on top of the filler block. The fastening bolts pass through the counter-pressure block, filler block, pad block, and beam flange template sequentially from top to bottom. The elastic combined grout-stopping strip is tightly connected to the beam flange template, and the rubber blocks compress against each other to achieve the grout-stopping effect. It is mainly used for grout-stopping at the outer end of precast beam flanges and cantilevered beam flanges, offering good grout-stopping effect, strong versatility, and convenient construction. However, the aforementioned grout-stopping structure suffers from insufficient sealing during use. After being pasted onto the template, air bubbles in the adhesive layer cannot be effectively removed, and the pressure of the concrete cannot automatically drive the grout-stopping strip into the template. Summary of the Invention

[0005] The purpose of this invention is to provide a grout-stopping strip that does not require roughening, in order to solve the problems that existing grout-stopping strips cannot be stably connected along their width direction and cannot be automatically nailed into the formwork by the pressure of concrete.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a non-chiseling grout-stopping tape, comprising a grout-stopping tape body, wherein a mechanical interlocking layer is installed on the grout-stopping tape body, the mechanical interlocking layer comprising a wedge-shaped anchoring area and a secondary attachment area fixedly connected to the grout-stopping tape body, an adhesive block is installed on one side of the grout-stopping tape body, a butt groove is provided on the other side of the grout-stopping tape body, a first adhesive layer is provided at the bottom of the grout-stopping tape body, a first release paper is provided below the first adhesive layer, a connecting groove is provided on the bottom surface of the grout-stopping tape body, an extrusion groove is provided on the first adhesive layer, grooves are provided on the wedge-shaped anchoring areas located on both sides of the grout-stopping tape body, a pressure block and an anti-accidental contact component are slidably installed in the grooves, a connecting post is fixedly connected to the pressure block, a pressure spring is pressed and installed in the connecting post, a pressure plate is fixedly connected below the pressure spring, a trigger component is provided below the pressure plate, a straight nail is slidably installed in the connecting post, and through holes for the straight nail to pass through are provided on the grout-stopping tape body, the first adhesive layer and the first release paper.

[0007] As a further embodiment of the present invention: an adhesive component is installed on the adhesive block, the adhesive component includes a second release paper disposed around the adhesive block, a folded layer is fixedly connected to the second release paper, and a connecting rope is fixedly connected between two adjacent folded layers.

[0008] As a further embodiment of the present invention: the adhesive blocks are evenly distributed on the grout-stopping strip body, and the positions and quantities of the adhesive blocks and the docking grooves correspond one-to-one.

[0009] As a further embodiment of the present invention: the mechanical interlocking layer is uniformly distributed on the surface of the grout-stopping strip body, and the wedge-shaped anchoring area and the secondary attachment area are alternately distributed on the surface of the grout-stopping strip body.

[0010] As a further embodiment of the present invention: the wedge-shaped anchoring area is a right-angled triangular prism with the inclined surface facing upwards, and the secondary attachment area is composed of multiple parallel convex strips with undulating surface structures.

[0011] As a further embodiment of the present invention: a sealing plate is fixedly connected to the pressure block, and the pressure block, the sealing plate and the connecting column are fixedly connected as an integral structure, and the sealing plate is slidably connected to the wedge-shaped anchoring area.

[0012] As a further embodiment of the present invention: the anti-accidental touch component includes a docking plate slidably installed in the groove, a connecting plate fixedly connected to the docking plate, and a second adhesive layer provided on the connecting plate.

[0013] As a further embodiment of the present invention: the triggering component includes a stop block slidably installed in the connecting column, a connecting belt fixedly connected to the stop block, a traction steel rope fixedly connected to the lower part of the connecting belt, a connecting plate fixedly connected to the end of the traction steel rope, a guide groove for guiding the traction steel rope provided in the connecting column, a guide wheel for guiding the connecting belt rotatably installed in the connecting column, a first moving groove and a second moving groove opened in the body of the grout-stopping belt, and a pressure rod installed in the body of the grout-stopping belt.

[0014] As a further embodiment of the present invention: a damping block is installed on the stop block. The damping block is made of rubber and abuts against the connecting column. The upper and lower sides of the first and second moving grooves are both through-hole structures. The position of the second moving groove corresponds to the position of the pressure rod.

[0015] As a further embodiment of the present invention: the straight nail is provided with mounting grooves on all four sides, a rotating shaft is rotatably connected in the mounting groove, and oblique nails are fixedly connected on the rotating shaft, with the oblique nails evenly distributed on the rotating shaft.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The wedge-shaped anchoring zone and secondary attachment zone enhance the anchoring effect between the grout seal and the concrete, preventing displacement or detachment during concrete pouring and ensuring the positioning stability of the grout seal during construction. At the same time, the double-layered interlocking structure can form a multi-point embedding interface after the concrete hardens, improving the bonding strength and sealing performance between the grout seal and the concrete.

[0018] By using a set of adhesive blocks, adhesive components, and mating grooves, the function of mating multiple grout-stopping strips along the width direction is realized. When the grout-stopping strip is used to adapt to multiple gaps of different heights, in order to avoid the grout-stopping strip failing to align with the gap and thus resulting in poor sealing effect, the connecting rope can be pulled after mating to make the second release paper and folded layer detach from the adhesive block. This ensures the firmness of the connection after mating two adjacent grout-stopping strips. It solves the problem that the sides of the existing grout-stopping strip are easily lifted up under concrete pressure when used for multiple gaps. This grout-stopping strip has the advantage of stronger stability.

[0019] The device is equipped with a triggering component and an anti-accidental-touch component. After the grout-stopping tape is attached to the formwork, when concrete is poured, the inclined surface of the pressure block is compressed under the pressure of the concrete, generating a downward component force. This causes the pressure block to move downward, causing the pressure rod to abut against the connecting plate. When the connecting plate moves upward, it pulls the traction steel rope, which in turn pulls the connecting tape, causing the stop block to gradually retract until it no longer obstructs the pressure plate. Under the pressure of the compression spring, the pressure plate quickly pushes the straight nail, driving it into the formwork. This achieves the function of secondary anchoring and solves the problem that existing grout-stopping tapes cannot automatically drive into the formwork using the pressure of concrete.

[0020] The grout-stopping strip is equipped with an extrusion groove and a through groove running from front to back. When the grout-stopping strip is pasted with the template, if air bubbles are generated in the first adhesive layer, the gas can be forced through the extrusion groove into the through groove by pressing the grout-stopping strip, and then discharged from the grout-stopping strip body through the through groove. This ensures the firmness of the grout-stopping strip and avoids the loose adhesion caused by air bubbles. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0035] Example 1: As Figures 1-11As shown, this embodiment proposes a non-chiseling grout-stopping tape, including a grout-stopping tape body 1. A mechanical interlocking layer 7 is installed on the grout-stopping tape body 1. The mechanical interlocking layer 7 includes a wedge-shaped anchoring area 701 and a secondary attachment area 702 fixedly connected to the grout-stopping tape body 1. The wedge-shaped anchoring area 701 and the secondary attachment area 702 on the mechanical interlocking layer 7 are used to improve the anchoring effect between the grout-stopping tape body 1 and the concrete. An adhesive block 2 is installed on one side of the grout-stopping tape body 1, and a butt groove 3 is provided on the other side. A first adhesive layer 4 is provided at the bottom of the grout-stopping tape body 1, and a first release paper 5 is provided below the first adhesive layer 4. A connecting groove 6 is opened on the bottom surface of the grout-stopping tape body 1, and an extrusion groove 22 is opened on the first adhesive layer 4. When the grout-stopping tape is applied... When the main body 1 is pasted onto the template, the air bubbles in the first adhesive layer 4 after pasting can be pushed into the connecting groove 6 through the squeezing groove 22 by pressing the main body 1 of the grout-stopping tape. The gas is then discharged from the main body 1 of the grout-stopping tape through the connecting groove 6. The wedge-shaped anchoring areas 701 on both sides of the main body 1 of the grout-stopping tape are provided with grooves 9. The pressure block 10 and the anti-accidental contact component 14 are slidably installed in the grooves 9. The pressure block 10 is fixedly connected to the connecting post 12. The connecting post 12 is pressed with a compression spring 13. The pressure plate 15 is fixedly connected below the compression spring 13. The trigger component 16 is provided below the pressure plate 15. The connecting post 12 is slidably installed with a straight nail 18. The main body 1 of the grout-stopping tape, the first adhesive layer 4 and the first release paper 5 are all provided with through holes 17 for the straight nail 18 to pass through. When the grout-stopping tape body 1 is used to fit multiple gaps, multiple grout-stopping tape bodies 1 are joined together along the width direction. The adhesive block 2 on the grout-stopping tape body 1 is installed into the joint groove 3 of another grout-stopping tape body 1. This prevents the edges of the grout-stopping tape body 1 from lifting due to concrete pressure because it cannot be aligned with the gap, thus affecting the sealing effect. Remove the first release paper 5, and stick the grout-stopping tape body 1 to the inner wall of the template through the first adhesive layer 4. Take out the anti-accidental contact component 14 in the groove 9, so that when the concrete is poured, the grout-stopping tape body 1 can use the concrete pressure to act on the pressure block 10, causing the pressure block 10 to move downward. With the help of the trigger component 16, the straight nail 18 is automatically driven into the wooden template, completing the secondary anchoring.

[0036] Example 2: The solution in Example 1 will be further described below with reference to its specific working method. See the description below for details:

[0037] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in a preferred embodiment, based on the above method, the adhesive block 2 is further provided with an adhesive component 8. The adhesive component 8 includes a second release paper 802 disposed around the adhesive block 2. A folded layer 803 is fixedly connected to the second release paper 802. A connecting rope 801 is fixedly connected between two adjacent folded layers 803. After the adhesive block 2 is installed, the folded layers 803 are pulled by the connecting rope 801, and the connecting rope 801 removes the second release paper 802 around the adhesive block 2, so that the adhesive block 2 is installed while maintaining a smooth surface. After aligning with two adjacent anti-grouting tape bodies 1, the two are firmly adhered, which enhances the convenience of use.

[0038] like Figures 1-3 As shown, in a preferred embodiment, based on the above method, the adhesive blocks 2 are further distributed at equal intervals on the grout-stopping strip body 1. The positions and numbers of the adhesive blocks 2 and the docking grooves 3 correspond one-to-one. Furthermore, the positions of the docking grooves 3 correspond to the positions of the secondary attachment areas 702 on both sides of the grout-stopping strip body 1. This allows the device to ensure docking stability while avoiding the docking structure from affecting the anchoring structure at the bottom of the wedge-shaped anchoring area 701.

[0039] like Figures 1-3 As shown, in a preferred embodiment, based on the above method, the mechanical interlocking layer 7 is further evenly distributed on the surface of the grout-stopping strip body 1, and the wedge-shaped anchoring area 701 and the secondary attachment area 702 are alternately distributed on the surface of the grout-stopping strip body 1. The wedge-shaped anchoring area 701 is a right-angled triangular prism with the inclined surface facing upwards, and the secondary attachment area 702 is composed of multiple parallel convex strips with undulating surface structures, which enhances the anchoring effect between the grout-stopping strip and the concrete, prevents the grout-stopping strip body 1 from shifting or falling off during the concrete pouring process, and enhances the overall stability.

[0040] like Figure 6 As shown, in a preferred embodiment, based on the above method, a sealing plate 11 is further fixedly connected to the pressure block 10. The pressure block 10, the sealing plate 11 and the connecting column 12 are fixedly connected as an integral structure. The sealing plate 11 is slidably connected to the wedge-shaped anchoring area 701 to prevent the sealing plate 11 from seeping into the groove 9 and to ensure the overall stability of the grout-stopping strip.

[0041] like Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the anti-accidental triggering component 14 further includes a docking plate 1401 slidably installed in the groove 9, a connecting plate 1402 fixedly connected to the docking plate 1401, and a second adhesive layer 1403 provided on the connecting plate 1402. Before the grout stop strip is transported, the docking plate 1401 is first installed into the groove 9, and then the connecting plate 1402 is bonded to the grout stop strip through the second adhesive layer 1403, thereby preventing the secondary anchoring structure from being accidentally triggered before the concrete is poured.

[0042] like Figures 6-8 As shown, in a preferred embodiment, based on the above method, the triggering component 16 further includes a stop block 1601 slidably installed in the connecting column 12, a connecting belt 1603 fixedly connected to the stop block 1601, a traction steel rope 1605 fixedly connected below the connecting belt 1603, a connecting plate 1606 fixedly connected to the end of the traction steel rope 1605, a guide groove 1610 for guiding the traction steel rope 1605 provided in the connecting column 12, a guide wheel 1604 for guiding the connecting belt 1603 rotatably installed in the connecting column 12, and a first movable section opened in the grout-stopping belt body 1. The groove 1607 and the second moving groove 1609, and the grout-stopping strip body 1 are equipped with a pressure rod 1608. When pouring concrete, the concrete pressure acts on the pressure block 10, causing the pressure block 10 to move downward. The top of the pressure rod 1608 pushes the connecting plate 1606. The connecting plate 1606 pulls the traction steel rope 1605 in the guide groove 1610. The traction steel rope 1605 pulls the stop block 1601 through the connecting belt 1603 and the guide wheel 1604, so that the stop block 1601 no longer blocks the pressure plate 15. Under the elastic force of the compression spring 13, the pressure plate 15 can push the straight nail 18 to quickly drive into the template, realizing the secondary anchoring function.

[0043] like Figures 6-7 As shown, in a preferred embodiment, based on the above method, a damping block 1602 is further installed on the stop block 1601. The damping block 1602 is made of rubber and abuts against the connecting post 12. The upper and lower sides of the first moving groove 1607 and the second moving groove 1609 are open structures. The position of the second moving groove 1609 corresponds to the position of the pressure rod 1608. The damping block 1602 ensures that the stop block 1601 can block the pressure plate 15 in the initial state, preventing the pressure plate 15 from moving easily. The first moving groove 1607 and the second moving groove 1609 allow the connecting plate 1606 and the pressure rod 1608 to move vertically up and down.

[0044] like Figure 5 , Figure 7 , Figure 10 and Figure 11 As shown, in a preferred embodiment, based on the above method, the straight nail 18 is further provided with mounting grooves 19 on all four sides. A rotating shaft 20 is rotatably connected in the mounting groove 19, and a beveled nail 21 is fixedly connected on the rotating shaft 20. The beveled nails 21 are evenly distributed on the rotating shaft 20. When the straight nail 18 is driven into the template, as the straight nail 18 moves away from the template, the beveled nails 21, which are inclined in the mounting groove 19, can play a role in preventing them from falling off, thereby enhancing the stability of the anchoring structure.

[0045] Example 3: The solutions in Examples 1 and 2 will be further described below with reference to their specific working methods. See the description below for details:

[0046] Specifically, when using this no-scraping grout-stopping tape: ... Figures 1-8 As shown, before transportation, the butt plate 1401 of the grout-stopping strip body 1 is first installed into the groove 9, and then the connecting plate 1402 is bonded to the grout-stopping strip through the second adhesive layer 1403, thereby avoiding accidental triggering of the secondary anchoring structure before concrete pouring. After the template is installed and the grout-stopping strip body 1 is used, the first release paper 5 is removed, and the grout-stopping strip body 1 is pasted to the inner wall of the template through the first adhesive layer 4. When pasting the grout-stopping strip body 1 onto the template, air bubbles between the first adhesive layer 4 and the template can be released by pressing the grout-stopping strip body 1, allowing the gas to enter the connecting groove 6 through the extrusion groove 22, and then be discharged outside the grout-stopping strip body 1 through the connecting groove 6. Before calibrating the concrete, the anti-accidental triggering component 14 in the groove 9 is removed, so that the pressure block 10 in the groove 9 is not obstructed. At this time, when pouring concrete into the template, the grout-stopping strip body 1 can use the concrete pressure to act on the pressure block 10, causing the pressure block 10 to move downwards, and cooperate with the triggering component 16 to automatically drive the straight nail 18 into the wooden template, completing the secondary anchoring. Figures 5-8 As shown, concrete pressure acts on the pressure block 10, causing it to move downwards. The top of the pressure rod 1608 pushes the connecting plate 1606, and the connecting plate 1606 pulls the traction steel rope 1605 in the guide groove 1610. The traction steel rope 1605 pulls the stop block 1601 through the connecting belt 1603 and the guide wheel 1604, so that the stop block 1601 no longer blocks the pressure plate 15. Under the elastic force of the compression spring 13, the pressure plate 15 can push the straight nail 18 to quickly drive into the template. When the straight nail 18 moves away from the template, the inclined nail 21, which is inclined in the installation groove 19, can play a role in preventing it from falling off, thus ensuring the stability of the secondary anchoring structure. The damping block 1602 ensures that the stop block 1601 can block the pressure plate 15 in the initial state, preventing the pressure plate 15 from moving easily. The first moving groove 1607 and the second moving groove 1609 allow the connecting plate 1606 and the pressure rod 1608 to move vertically up and down. The wedge-shaped anchoring area 701 and the secondary attachment area 702 on the mechanical interlocking layer 7 are used to improve the anchoring effect between the grout-stopping strip body 1 and the concrete.

[0047] like Figures 1-5As shown, when the grout-stopping tape body 1 is used to fit multiple gaps, multiple grout-stopping tape bodies 1 are joined together along the width direction. The adhesive block 2 on the grout-stopping tape body 1 is installed into the docking groove 3 of another grout-stopping tape body 1. After installing the adhesive block 2, the folded layer 803 around the adhesive block 2 is pulled by the connecting rope 801, thereby removing the second release paper 802 around the adhesive block 2 while maintaining the docking state. The docking area is pressed to make the two grout-stopping tape bodies 1 stably docked, so that the adhesive block 2 can be docked easily while keeping the surface smooth. This avoids the grout-stopping tape body 1 from being unable to align with the gap, causing the edge of the grout-stopping tape body 1 to lift up due to concrete pressure, thus ensuring the sealing effect of the grout-stopping tape body 1 after docking.

[0048] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
