Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a reusable small channel steel opening tool-based formwork mold. Background Technology

[0002] The research and application of tool-based formwork for small channel steel openings stems from the comprehensive needs of increasingly complex building functions, improved construction efficiency and quality requirements, industrial transformation, and upgraded safety standards.

[0003] A search revealed Chinese patent CN210289130U, which discloses a wall opening formwork tool. The tool includes a front template, a back template, a sloping hopper, and connecting components for fixing the front and back templates. The front template has a filling port on its upper surface, and a laterally extending U-shaped groove is fixed to the front template below the filling port. The lower side of the sloping hopper is inserted into the U-shaped groove, and both sides of the sloping hopper are in close contact with the front template. The upper sides of the sloping hopper are fixedly connected to the front template via locking components. This utility model has a simple structure, is easy to operate, and simplifies the wall opening formwork sealing process, improving the sealing quality and the appearance of the finished product.

[0004] Based on the above search and existing patents;

[0005] The aforementioned patents use a method of directly filling the opening with mortar or fine stone concrete to seal it, which makes it impossible to vibrate the area and seal the vertical opening tightly. Furthermore, one side of the opening cannot be smoothed and finished, thus presenting certain limitations. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a reusable small channel steel opening tool formwork, which is easy to install, reusable, and suitable for small vertical openings of different heights.

[0007] The technical solution to achieve the purpose of this utility model is: a reusable small channel steel opening tool formwork, including a floor slab, wall one and wall two, and also including;

[0008] Inner formwork, which is fixedly installed on one side of the floor slab;

[0009] The outer formwork is fixedly installed on the surface of the floor slab.

[0010] Preferably, template slides are provided on both the upper and lower sides of the inner template, and an adjustable template is slidably installed inside each template slide. An adjustable hopper opening is provided at the top of the outer template. An adjustable button two is fixedly installed on the inner template, and an adjustable button one is fixedly installed on the outer template.

[0011] Preferably, a screw is welded together between the inner template and the outer template. One end of the screw passes through the outer template and is fitted with a nut. A washer is provided between the nut and the outer template. The other end of the screw passes through the inner template and is provided with a screw thread.

[0012] Preferably, a plastic sleeve is fitted around the screw, and rubber sealing rings are fixedly installed between the end of the plastic sleeve and both the outer and inner templates. A long sleeve is provided below the screw thread, and a sleeve thread is provided at one end of the long sleeve.

[0013] Compared with existing technologies, the significant advantages of this invention are:

[0014] Firstly, this utility model, through its modular and adjustable aluminum alloy template design, combined with innovative demolition and pouring optimization, achieves a comprehensive improvement in construction efficiency, quality, and environmental protection. It is easy to install, reusable, and suitable for small vertical openings of different heights, thus improving both economy and safety.

[0015] Secondly, the addition of sealing rubber gaskets and plastic sleeves to this utility model improves the overall sealing performance, ensuring the protection of the tie rods during concrete pouring, and facilitating reuse after demolding, reducing material waste, lowering the demand for customized non-standard templates, and reducing material loss during construction; at the same time, the integrated structure reduces the number of support components, saving costs.

[0016] This method solves the problem that existing construction methods, which involve directly filling the opening with mortar or fine aggregate concrete, make it impossible to vibrate the area, thus making it difficult to seal the vertical opening tightly and preventing the opening from being smoothed and finished on one side.

[0024] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0025] This utility model provides an improved, reusable, small-sized, tool-based formwork for channel steel openings. The technical solution of this utility model is as follows:

[0026] like Figure 1-4 As shown, a reusable small channel steel opening tool formwork includes a floor slab 1, a wall 1 2, and a wall 2 201, which facilitates sealing of the device, and also includes;

[0027] Inner template 3 is fixedly installed on one side of floor slab 1. The entire device is made of aluminum alloy and high-quality steel, which has good corrosion resistance.

[0028] The outer formwork 4 is fixedly installed on the surface of the floor slab 1, providing a construction foundation for sealing the opening and playing a very good auxiliary role.

[0029] Furthermore, template slides 301 are provided on both the upper and lower sides of the inner template 3, and an adjustable template 6 is slidably installed inside each template slide 301. An adjustable hopper opening 5 is provided at the top of the outer template 4. An adjustable button 2 16 is fixedly installed on the inner template 3, and an adjustable button 15 is fixedly installed on the outer template 4. The inner template 3 is provided with an internal template piece that can be adjusted vertically, and the height can be adjusted.
