Description

Technical Field

[0001] This utility model relates to the field of building sealing technology, specifically to a grouting and sealing device for PPVC. Background Technology

[0002] Against the backdrop of the promotion of industrialized building and prefabricated structures, PPVC is widely used. The core of its installation quality lies in the treatment of joints, especially the sealing effect of horizontal and vertical joints.

[0003] Traditional joint sealing usually uses wooden molds. Wooden molds need to be cut on site, which is inefficient. In addition, there are gaps between the wooden molds and the concrete surface, making it difficult to fit tightly. The gaps result in a high permeability during grouting. The wooden molds are usually fixed by drilling and tying, which can easily damage the integrity of PPVC.

[0004] Therefore, a grouting and sealing device for PPVC is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a grouting and sealing device for PPVC, which can solve the problems of low installation efficiency and high permeability when sealing with wooden molds.

[0006] To achieve the above objectives, this utility model provides the following technical solution: including a slot and a mortar fixing plate, at least two springs are arranged opposite each other on the inner wall of the slot, an injection clamp is fixedly arranged at one end of the spring near the center of the slot, a plurality of diamond-shaped ridges are fixedly arranged on the side of the injection clamp near the spring, a mortar plate limiting block is fixedly arranged on the outer side of the slot, and a mortar plate placement cavity is opened through the surface of the mortar plate limiting block, the mortar plate placement cavity extending to the outer side of the mortar plate limiting block.

[0007] Preferably, the glue injection clamp is a hollow structure, and the lower opening of the glue injection clamp is a conical guide structure. The glue injection clamp is slidably disposed inside the slot, and a glue gun fixing bucket is fixedly disposed at the upper end of the glue injection clamp.

[0008] Preferably, the glue gun fixing barrel is configured as a hollow cylindrical structure, and the upper end of the glue injection clamp is provided with a glue gun head fixing hole, which connects the glue gun fixing barrel and the internal space of the glue injection clamp.

[0009] Preferably, the upper end of the glue gun fixing barrel is provided with a glue gun body fixing hole, which extends to the top of the glue gun fixing barrel.

[0010] Preferably, the diamond-shaped raised pattern array on one side of the glue injection clamp is distributed on the surface of the glue injection clamp, and the diamond-shaped raised pattern is disposed below the spring.

[0011] Preferably, the mortar fixing plate is configured as a plate structure, the width of the mortar fixing plate is set as the joint distance between every two PPVC particles, and a number of finger grip holes are provided through one side of the mortar fixing plate, the finger grip holes being distributed in an array.

[0012] Preferably, the upper width of the mortar board placement cavity is greater than the lower width, forming a tapered structure, and the inner wall of the mortar board placement cavity is provided with a serrated structure.

[0013] Compared with the prior art, this utility model provides a grouting and sealing device for PPVC, which has the following beneficial effects:

[0014] 1. This utility model uses a mortar board placement cavity with a wider upper part and a narrower lower part to guide the mortar fixing plate to be quickly aligned and positioned, reducing alignment time. The serrated structure on the inner wall increases the biting force with the mortar fixing plate, preventing the fixing plate from shifting during mortar pouring. It can also clean the surface of the fixing plate when it is pulled out, ensuring the mortar forming quality and the reusability of the fixing plate.

[0015] 2. This utility model, through the hollow structure of the glue injection clamp and the tapered guide structure at the lower end, combined with its slidable setting, can accurately guide the glue injected by the glue gun to the gap between the sponge strip and the side of the PPVC, ensuring that the glue is concentrated on the target position and enhancing the fixing effect of the sponge strip.

[0016] 3. This utility model applies elastic pressure to the side of PPVC by cooperating with the springs and glue injection clamps arranged opposite to each other on the inner wall of the slot. Combined with the diamond-shaped ridges on the surface of the glue injection clamps to increase friction, it achieves double fixation between the device and PPVC, effectively preventing the device from sliding during construction and improving operational stability.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figure 1 - Figure 5 In this embodiment, a grouting and sealing device for PPVC includes a slot 1 and a mortar fixing plate 2. At least two springs 3 are arranged opposite each other on the inner wall of the slot 1. An injection clamp 4 is fixedly arranged at one end of the spring 3 near the center of the slot 1. Several diamond-shaped ridges are fixedly arranged on the side of the injection clamp 4 near the spring 3. A mortar plate limiting block 8 is fixedly arranged on the outer side of the slot 1. A mortar plate placement cavity 9 is opened through the surface of the mortar plate limiting block 8 and extends to the outer side of the mortar plate limiting block 8.

[0026] When preparing to seal a horizontal joint, first place a compressible sponge strip inside the joint. Then, squeeze the glue injection clamp 4 into the groove 1 to compress the spring 3. When the two glue injection clamps 4 are close to a certain extent, insert the glue injection clamp 4 into the joint and position it above the sponge strip. Under the action of the spring 3, the glue injection clamp 4 adheres to the PPVC side, achieving double fixation with the user's manual fixation. The diamond-shaped ridges increase friction and prevent the device from sliding. Then, fix the glue gun above the glue injection clamp 4 and inject glue to fix the sponge strip. The mortar board placement cavity 9 is used for subsequent insertion of the mortar fixing plate 2 to assist in completing the mortar pouring and shaping, thus completing the sealing operation.

[0027] The glue injection clamp 4 is configured as a hollow structure, and the lower opening of the glue injection clamp 4 is configured as a conical guide structure. The glue injection clamp 4 is slidably disposed inside the slot 1, and a glue gun fixing bucket 6 is fixedly disposed on the upper end of the glue injection clamp 4.

[0028] During operation, slide the glue injection clamp 4 to the glue injection position, rely on the tension of the spring 3 for initial positioning, insert the glue gun into the glue gun fixing barrel 6, and use the conical guide structure to make the glue flow to the gap between the sponge strip and the side of the PPVC to fix the sponge strip.

[0029] The glue gun fixing barrel 6 is a hollow cylindrical structure. The glue gun head fixing hole 5 is opened through the upper end of the glue injection clamp 4. The glue gun head fixing hole 5 connects the glue gun fixing barrel 6 and the internal space of the glue injection clamp 4. The glue gun body fixing hole 7 is opened through the upper end of the glue gun fixing barrel 6, and the glue gun body fixing hole 7 extends to the top of the glue gun fixing barrel 6.

[0030] When preparing to inject glue, the glue gun head is inserted into the glue gun head fixing hole 5 through the glue gun fixing barrel 6, and the glue gun body is inserted into the glue gun body fixing hole 7. After the glue flows out of the glue gun, it goes straight to the inside of the glue injection clamp 4 along the channel, and then is precisely injected into the target gap through the lower conical guide structure.

[0031] A diamond-shaped raised pattern array is distributed on one side of the glue injection clamp 4 surface, and the diamond-shaped raised pattern is set below the spring 3;

[0032] When the device is inserted into the PPVC seam, the spring 3 stretches to make the glue-injecting clamp 4 fit against the side of the PPVC seam. The diamond-shaped ridges are embedded in the tiny gaps on the PPVC surface or rub against the PPVC surface to increase the contact friction. Combined with the elastic pressure of the spring 3, this prevents the device from sliding.

[0033] The mortar fixing plate 2 is configured as a plate structure. The width of the mortar fixing plate 2 is set as the joint distance between every two PPVC particles. Several finger grip holes 10 are provided through one side of the mortar fixing plate 2. The finger grip holes 10 are distributed in an array.

[0034] During construction, the operator inserts their fingers into the finger gripping hole 10 and inserts the mortar fixing plate 2 into the mortar plate placement cavity 9 to seal and shape the PPVC joint with mortar.

[0035] The upper width of the mortar board placement cavity 9 is greater than the lower width, forming a tapered structure, and the inner wall of the mortar board placement cavity 9 is provided with a serrated structure.

[0036] When the mortar fixing plate 2 is inserted into the mortar plate placement cavity 9, the closing structure guides it to quickly align and be in place. The serrated structure rubs against the surface of the mortar fixing plate 2, increasing the biting force between the mortar fixing plate 2 and the mortar plate limiting block 8, preventing the mortar fixing plate 2 from shifting during mortar pouring. At the same time, when the mortar is set, the mortar fixing plate 2 is pulled out, and the serrated structure cleans the surface of the mortar fixing plate 2.

[0037] The working principle of the above embodiment is as follows: When sealing the horizontal joint of PPVC, a compressible sponge strip is first placed in the joint. The glue injection clamp 4 in the slot 1 is squeezed to compress the spring 3. The glue injection clamp 4 is inserted into the joint and placed above the sponge strip. The spring 3 makes the glue injection clamp 4 fit against the side of PPVC. The diamond-shaped ridge on its surface, together with the elastic pressure of the spring 3, increases the friction and prevents slippage. The glue gun is connected to the glue injection clamp 4 by using the glue gun fixing bucket 6, the glue gun head fixing hole 5, and the glue gun body fixing hole 7. With the help of the tapered guide structure at the lower end of the glue injection clamp 4, the glue is accurately injected into the gap between the sponge strip and the side of PPVC to fix the sponge strip. The operator inserts his finger into the finger grip hole 10 of the mortar fixing plate 2 and inserts it into the mortar plate placement cavity 9 of the mortar plate limiting block 8 on the outside of the slot 1. The closing structure guides it into place. The sawtooth structure on the inner wall increases the biting force to prevent displacement during mortar pouring. After the mortar is shaped, the mortar fixing plate 2 is pulled out. The sawtooth can also clean its surface, and finally the grouting and sealing operation of PPVC joint is achieved.

[0038] The use of glue guns is a common technology. The installation, connection or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. They are common knowledge in the field. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
