Using this sealing device, the area of ​​the baffle covering the outer side of the opening can be adjusted while pouring, thus enabling rapid construction.

Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a device for quickly sealing openings in exterior walls. Background Technology

[0002] Currently, when sealing construction openings in exterior walls, it is typically necessary to install an outer formwork on the exterior wall side and an inner formwork on the interior wall side, securing the outer and inner formwork with a pair of tie rods. Grout is then injected into the construction opening through holes drilled in the inner formwork until the sealing is complete, at which point the formwork is removed.

[0003] Chinese patent application number 2018111732656 discloses a method for sealing openings in concrete exterior walls. The method comprises the following steps: inserting a sealing device component into the opening to be sealed in a retracted state; fitting a PVC pipe onto a fastening bolt; unfolding a high-density woven metal mesh and applying a concrete release agent after the sealing device component is inserted into the opening; applying a concrete release agent to the folded cover plate of the opening and fitting it tightly against the wall surface onto the fastening bolt; then clamping the entire component onto the wall using the fastening bolt; and finally fixing the folded cover plate of the opening by inserting a fixing pin into the fixing hole. After the concrete has solidified, the entire concrete opening sealing device component is removed. This method can seal holes inside the exterior wall without erecting scaffolding. However, the high-density woven metal mesh used in the sealing device is inconvenient to unfold and retract. Furthermore, after the template is dismantled, the aforementioned fastening bolts will form a small horizontal hole inside the hole. Even if this hole is sealed during the later exterior wall construction, the waterproofing effect will still be poor. Summary of the Invention

[0004] The technical solution adopted by this utility model to solve the aforementioned problem is:

[0005] A rapid sealing device for exterior wall openings is applied to the location of exterior wall openings. It includes an inner template and an outer template, which are respectively attached to the inner and outer sides of the opening. The inner and outer templates are connected by tie bolts. A baffle is slidably installed on the inner side of the outer template, and the top of the baffle is a pouring hopper protruding outward. When pouring the concrete for the opening, the pouring hopper is connected to the top of the opening. After the exterior wall opening is filled, the pouring hopper is located above the opening.

[0006] Compared with the prior art, the advantages of this utility model adopting the above technical solution are:

[0007] This invention uses inner and outer templates to seal the inner and outer sides of an opening. Tie bolts connect the inner and outer templates, ensuring a tight fit. A baffle and a pouring hopper are installed on the outer template. During pouring, concrete is poured into the opening through the hopper. When the opening is almost full, the hopper and baffle are pulled upwards, gradually reducing the area between the lower end of the hopper and the top of the opening. This causes the baffle to gradually seal the top of the opening until it is completely filled. The hopper is then pulled back to a position above the opening, and the baffle completely seals the outer side of the opening. Using this sealing device allows for simultaneous pouring and adjustment of the baffle's coverage area, enabling rapid construction.

[0008] As a preferred embodiment, a further technical solution of this utility model is:

[0009] A pouring opening is provided at the top of the middle position of the outer template, and a vertical sliding groove is provided on the inner side of the outer template. A baffle is vertically slidably installed in the sliding groove. When the baffle slides to the bottom of the sliding groove, the pouring hopper is located in the pouring opening. The baffle covers the outer side of the opening, and the baffle can be moved vertically to adjust the area of ​​the outer side of the opening covered by the baffle.

[0010] Limiting grooves are provided on the outer templates at both ends of the sliding groove. The horizontal cross-section of the limiting groove is T-shaped. Limiting blocks that cooperate with the limiting groove are provided on the outer sides of both ends of the baffle. The limiting blocks are slidably disposed in the limiting groove.

[0011] Both the sliding groove and the limiting groove extend to the top of the outer template. Through the cooperation of the limiting block and the limiting groove, the baffle can slide stably vertically on the outer wooden board without detaching from the outer template.

[0012] Through holes are provided on the outer walls on both sides of the opening. Tie bolts are installed in the through holes, with both ends of the tie bolts passing through the inner and outer formwork and connected with nuts. The tie bolts are installed on the outer walls on both sides of the opening, and the inner and outer formwork are fixedly connected by the tie bolts to avoid leaving holes when pouring concrete at the opening. After the concrete at the opening has solidified, the inner and outer formwork can be removed, and the excess tie bolts can be cut off.

[0013] A screw is threaded onto the outer template outside the limiting groove, and the inner end of the screw abuts against the limiting block. In use, the screw is tightened so that the inner end of the screw is pressed tightly against the limiting block in the limiting groove, thereby fixing the position of the limiting block in the limiting groove.

[0018] The present invention will be further described below with reference to embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0019] Reference Figure 1-3 This application discloses a quick sealing device for an external wall opening 7, applied to the location of the external wall opening 7. It includes an inner template 8 and an outer template 1, both made of wood. The height of the outer template 1 and the inner template 8 is greater than the height of the opening. The inner template 8 and the outer template 1 are respectively attached to the inner and outer sides of the opening. The inner template 8 and the outer template 1 are connected by tie bolts 2. A baffle 5 is slidably provided on the inner side of the outer template 1. The top of the baffle 5 is a pouring hopper 4 protruding outward. The width of the pouring hopper 4 is greater than the width of the opening. The pouring hopper 4 is a sloping groove shape with the top inclined outward and the bottom inclined inward. When pouring the opening, the bottom of the pouring hopper 4 is connected to the top of the opening. When the external wall opening 7 is filled, the pouring hopper 4 is located above the opening.

[0020] In this embodiment, a pouring opening 11 is provided at the top of the middle position of the outer template 1. The height of the pouring opening 11 is equal to the height of the pouring hopper 4, and the width of the pouring opening 11 is greater than or equal to the maximum outer width of the pouring hopper 4. A vertical sliding groove 42 is provided on the inner side of the outer template 1. A baffle 5 is vertically slidably disposed in the sliding groove 42. When the baffle 5 slides to the bottom of the sliding groove 42, the pouring hopper 4 is located in the pouring opening 11. The outer side of the opening is blocked by the baffle 5 and the outer template 1, and the baffle 5 can be moved vertically to adjust the area of ​​the outer side of the opening blocked by the baffle 5.

[0021] In this embodiment, a limiting groove is provided on the outer template 1 on both sides of the sliding groove 42. The horizontal cross section of the limiting groove is T-shaped. Limiting blocks 41 that cooperate with the limiting groove are provided on both sides of the baffle 5. The limiting blocks 41 are slidably disposed in the limiting groove.

[0022] In this embodiment, both the sliding groove 42 and the limiting groove extend to the top of the outer template 1. Through the cooperation of the limiting block 41 and the limiting groove, the baffle 5 can slide stably vertically on the outer wooden board without detaching from the outer template 1.

[0023] In this embodiment, through holes are provided on the outer walls 7 on both sides of the opening. Tie bolts 2 are installed in the through holes, and both ends of the tie bolts 2 pass through the inner template 8 and the outer template 1, and are connected with nuts 3. The tie bolts 2 are inserted into the outer walls 7 on both sides of the opening, and the inner template 8 and the outer template 1 are fixedly connected by the tie bolts 2, avoiding leaving holes when pouring concrete at the opening. After the concrete at the opening has solidified, the inner template 8 and the outer template 1 can be removed, and the excess tie bolts 2 can be cut off.

[0024] In this embodiment, a screw 6 is threadedly connected to the outer template 1 outside the limiting groove, and the inner end of the screw 6 abuts against the limiting block 41. In use, the screw 6 is tightened so that the inner end of the screw 6 is tightly abutted against the limiting block 41 in the limiting groove, thereby fixing the position of the limiting block 41 in the limiting groove.

[0025] This utility model seals the inner and outer sides of an opening using an inner template 8 and an outer template 1. Tie bolts 2 are used to connect the inner template 8 and the outer template 1, ensuring a tight fit between them. A baffle 5 and a pouring hopper 4 are installed on the outer template 1. To install the sealing device, holes are first drilled in the outer walls 7 on both sides of the opening. Then, the inner template 8 and the outer template 1 are placed together on the inner and outer sides of the opening. The tie bolts 2 are then passed through the holes, and nuts 3 are used to secure the inner template 8 and the outer template 1 together with the tie bolts 2. After securing the connection, pour concrete into the opening using the pouring hopper 4. When the opening is almost full, pull the pouring hopper 4 and the baffle 5 upwards, gradually reducing the area between the lower end of the pouring hopper 4 and the top of the opening. This allows the baffle 5 to gradually seal the top of the opening. When the opening is completely filled and concrete slightly overflows, pull the pouring hopper 4 to a position above the opening, ensuring the baffle 5 completely seals the outside of the opening. Tighten the bolt 6 to fix the position of the baffle 5. After the concrete in the opening has solidified, remove the nut 3, tie bolt 2, inner template 8, and outer template 1 in sequence. This sealing device is reusable. Using this sealing device allows for simultaneous pouring and adjustment of the area covered by the baffle 5 on the outside of the opening, enabling rapid construction.
