Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically, it relates to a standardized mold for sealing wall openings. Background Technology

[0002] Channel steel is used to support external scaffolding; it passes through the exterior walls and is secured to the floor slabs. Removing the channel steel leaves holes in the building structure that need to be sealed later. Inadequate sealing can lead to problems such as incomplete concrete sealing, honeycomb-like surfaces, and cracking, ultimately causing water leaks.

[0003] Since sealing the opening can only be done after the scaffolding and channel steel are removed, and there are no support points on the exterior facade of the structure, it is extremely difficult to formwork and pour concrete. If tools such as suspended scaffolds are used for construction, it will greatly increase labor and machinery costs, and traditional formwork and pouring methods cannot guarantee that the concrete at the opening is poured densely, which poses a significant quality risk. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a standardized mold for sealing wall openings, which can reduce the operational difficulty of sealing channel steel openings, reduce potential quality problems caused by workers setting up formwork and pouring concrete, and make the concrete pouring more compact.

[0005] The present invention adopts the following technical solution.

[0006] A standardized mold for sealing wall openings includes an outer steel plate and an inner steel plate. The outer steel plate is placed on the outer side of a concrete wall, and the inner steel plate is placed on the inner side of the concrete wall. The outer steel plate and the inner steel plate are connected by bolts. A plastic tie rod sleeve is sleeved on the outside of the bolts and is placed between the outer steel plate and the inner steel plate.

[0007] Furthermore, the outer steel plate is composed of two steel plates spliced ​​together. The two steel plates are connected by a splicing keel. One side of the splicing keel is provided with a one-way hinge shaft. One end of the two steel plates is connected to the one-way hinge shaft, so that the outer steel plate can rotate in the direction close to the bolt.

[0008] Furthermore, the dimensions of the outer steel plate are larger than the dimensions of the channel steel opening.

[0009] Furthermore, the inner steel plate is an integral steel plate with bolt holes. One end of the bolt is fixed to the splicing keel of the outer steel plate, and the other end passes through the bolt hole on the inner steel plate and is fixed with a nut.

[0010] Furthermore, the lower part of the inner steel plate is a vertical steel plate, and the upper part is an inclined steel plate; the bottom of the vertical steel plate is in close contact with the inner side of the concrete wall, and the upper part of the inclined steel plate is inclined at 30-45° away from the concrete wall.

[0011] The bottom of the inclined steel plate is 4-6cm below the top wall of the channel steel opening, and the top of the inclined steel plate is 4-6cm above the top wall of the channel steel opening.

[0012] Furthermore, the two sides of the inclined steel plate are connected to the fastener-type steel plate, which includes a triangular steel plate and fasteners. The triangular steel plate is connected to the inclined steel plate through the fasteners, and the gap between the inclined steel plate and the concrete wall is adapted to the triangular steel plate.

[0013] Furthermore, the length of the plastic tie-down sleeve is equal to the thickness of the concrete wall, with one end of the plastic tie-down sleeve connected to the outer steel plate and the other end connected to the inner steel plate.

[0014] Furthermore, the inner and outer steel plates are 5mm thick galvanized steel plates or aluminum alloy steel plates, the diameter of the plastic tie rod sleeve is 1cm, and the bolt length is 8-12cm longer than the thickness of the concrete wall.

[0015] The beneficial effects of this utility model are as follows: Compared with the prior art, the outer steel plate adopts a spliced ​​hinge structure, which can be folded through the opening and then unfolded and fixed, without relying on external scaffolding or suspended platform, adapting to construction scenarios without external facade support points and simplifying the operation process; the inclined design of the inner steel plate, combined with the fastener-type steel plate, can tightly fit the wall and seal gaps, reducing the risk of cracking and water leakage; the plastic tie rod sleeve accurately matches the wall thickness, and the bolt length is reserved with reasonable allowance to ensure the stability of the template.

The embodiments described in this application are merely some embodiments of this utility model, and not all embodiments. Based on the spirit of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1As shown, this utility model provides a standardized mold for sealing wall openings, including an outer steel plate 1, an inner steel plate 2, a fastener-type steel plate 3, bolts 4, and plastic tie rod sleeves 5.

[0020] The outer steel plate 1 is set on the outer side of the concrete wall 7, and the inner steel plate 2 is set on the inner side of the concrete wall 7. The outer steel plate 1 and the inner steel plate 2 are connected by bolts 4. A plastic tie tube 5 is sleeved on the outside of the bolts 4. The plastic tie tube 5 is set between the outer steel plate 1 and the inner steel plate 2.

[0021] The outer steel plate 1 is composed of two steel plates spliced ​​together by a splicing keel 11. The size of the outer steel plate 1 is larger than the size of the channel steel opening 8, ensuring that the outer steel plate 1 effectively seals the channel steel opening 8. A one-way hinge shaft is provided on one side of the splicing keel 11. One end of the two steel plates is connected to the one-way hinge shaft, allowing the outer steel plate 1 to rotate in the direction closest to the bolt 4.

[0022] The inner steel plate 2 is a single piece of steel plate with pre-drilled bolt holes. One end of the bolt 4 is fixed to the splicing keel 11 of the outer steel plate 1, and the other end passes through the pre-drilled bolt hole on the inner steel plate 2 and is fixed with a nut 6. The lower part of the inner steel plate 2 is a vertical steel plate 21, and the upper part is an inclined steel plate 22. The bottom of the vertical steel plate 21 is in close contact with the inner side of the concrete wall 7, and the upper part of the inclined steel plate 22 is inclined at 30°-45° away from the concrete wall 7. The connection between the inclined steel plate 22 and the vertical steel plate 21 is 4-6cm below the top wall of the channel steel opening 8, and the top of the inclined steel plate 22 is 4-6cm above the top wall of the channel steel opening 8. The inclined steel plate 22 is connected to the fastener-type steel plate 3 on both sides. The fastener-type steel plate 3 includes a triangular steel plate and fasteners. The triangular steel plate is connected to the inclined steel plate 22 through fasteners, and the gap between the inclined steel plate 22 and the concrete wall 7 is adapted to the triangular steel plate. The inclined steel plate 22 is sealed on both sides with the fastener-type steel plate 3 to ensure that no mortar leakage occurs.

[0023] The length of the plastic tie rod 5 is the thickness of the concrete wall 7. One end of the plastic tie rod 5 is connected to the outer steel plate 1, and the other end is connected to the inner steel plate 2.

[0024] The inner steel plate 2 and the outer steel plate 1 are 5mm thick galvanized steel plates or aluminum alloy steel plates. The diameter of the plastic tie rod sleeve 5 is 1cm. The length of the bolt 4 is 8-12cm longer than the thickness of the concrete wall 7.

[0025] This utility model also provides a method for using a standardized mold for sealing wall openings: During formwork erection, the outer steel plate is folded towards the bolts in advance. After passing through the opening, the folded outer steel plate is opened and its position adjusted so that the outer steel plate corresponds to the channel steel opening, ensuring a seamless exterior wall formwork and preventing mortar leakage. Plastic tie rod sleeves are fitted over the bolts, the bolts are tightened, and the bolts are passed through the inner steel plate and secured with nuts. Fine aggregate concrete of a grade one level higher than the wall surface is used for pouring. 2-3 hours after the concrete has fully set, the standardized mold for the channel steel opening is removed, and excess concrete at the corners is removed to make it flush with the structural wall surface. The completed channel steel opening also requires sealing the tie rod bolt holes. Special sealing foam for exterior walls is used for sealing. A 5cm mortar seal is left on both the inner and outer sides. The outer side can be sealed during the exterior wall insulation stage. Exterior waterproof coating is applied to the area exceeding 10cm from the opening, ensuring the thickness of the waterproof layer according to specifications.
