Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction technology, specifically relating to a simple double-wall formwork reinforcement device for concrete trenches. Background Technology
[0002] In the construction process of building engineering, the construction of small concrete components such as cable trenches and water ditches involves many steps, from the foundation to the bottom slab, then to the trench walls, reinforcement, formwork, and concrete. These steps are quite complicated. However, because of their relatively small size, they are often overlooked during construction. In particular, tie bolts are generally not used in the construction of trench walls. Since there are no professional reinforcement devices for the double-wall formwork of the trench, the formwork is prone to lateral displacement (formwork running), which affects the forming quality of the trench. Utility Model Content
[0003] The purpose of this utility model is to provide a simple concrete trench double-wall formwork reinforcement device, which adopts a frame structure and can effectively reinforce the trench double-wall formwork by inserting it into the trench. It is easy to use and the trench forming quality is high.
[0004] This utility model is achieved through the following technical solution: A simple double-wall formwork reinforcement device for concrete trenches is characterized by including a horizontal upper beam, a frame-type support in the middle of the upper beam, two right-angled triangular supports on each side of the frame-type support, the right-angled vertical sides of the two right-angled triangular supports being located on the inner side, and a trench gap between the frame-type support and the triangular supports.
[0005] This utility model is made of steel bars welded together, which is easy to obtain and durable. When in use, multiple frame-shaped supports are inserted into the groove in sequence at a certain distance (preferably 600-1000mm). The double walls of the groove are located in the gap between the two grooves. The right-angled triangular supports and frame supports effectively reinforce the double wall template of the groove.
[0006] This utility model is designed for different engineering water ditches, cable trenches, and small pools. Generally, trenches with a depth between 600-1000mm are made of 14mm diameter steel bars, while trenches with a depth between 200-600mm are made of 12mm diameter steel bars.
[0007] Furthermore, the frame-type bracket of this utility model includes two vertical legs, and at least one horizontal support rod is provided between the two vertical legs.
[0008] The present invention preferably provides two horizontal support rods between the two vertical support legs to ensure the strength of the frame bracket and provide sufficient support strength.
[0009] Furthermore, the upper crossbeam of this utility model is a threaded rod, the upper end of the triangular bracket is fitted onto the upper crossbeam through a sleeve, and fastening nuts are respectively fitted onto the upper crossbeam on both sides of the triangular bracket.
[0010] With the above setup, the triangular bracket can move left and right on the upper crossbeam by rotating the fastening nut, which can adjust the width of the groove gap to adapt to the use of groove walls of different widths.
[0011] This utility model has the advantages of simple structure, low cost, quick and convenient use, and good reinforcement effect on double-wall formwork of trenches. Using this utility model, the trench wall formwork does not require additional tie bolts for connection; it can be used with a hand hammer for embedding or disassembly during construction, resulting in fast construction speed, easy assurance of project quality, and good overall construction effect.

[0014] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present utility model and are not intended to limit its scope of protection. It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which this utility model pertains. Example 1
[0015] like Figure 1 As shown, the present invention is made of steel bars with a diameter of 14mm welded together. A frame-type support 2 is provided in the middle of the upper crossbeam 1. The frame-type support 2 includes two vertical legs and a horizontal support rod between the two vertical legs. Two right-angled triangular supports 3 are provided on both sides of the frame-type support 2. The right-angled vertical sides of the two right-angled triangular supports 3 are located on the inner side. A groove gap 4 is provided between the frame-type support 2 and the triangular supports 3.
[0016] When using this utility model, multiple reinforcing devices are inserted into the groove at 600mm intervals using a hand hammer. The double walls of the groove are located in the gap 4 between the two grooves. The right-angled triangular bracket 3 and the frame bracket 2 effectively reinforce the double wall template of the groove.
[0017] Once the trench construction is complete, the reinforcement device can be removed using a hand hammer.
[0018] This embodiment is particularly suitable for double-arm formwork for straight grooves, and is also applicable to the reinforcement of double-wall formwork for circular grooves. Example 2
[0019] like Figure 2 As shown: the upper crossbeam 1 is a threaded rod, the upper end of the triangular bracket 3 is fitted onto the upper crossbeam 1 through the sleeve 5, and fastening nuts 6 are respectively fitted onto the upper crossbeam 1 on both sides of the triangular bracket 3. The frame bracket 2 includes two vertical legs, and two horizontal support rods are provided between the two vertical legs. Other embodiments are the same as in Example 1.
[0020] In this embodiment, the usage is the same as in embodiment 1, except that by rotating the fastening nut 6, the triangular bracket 3 can move left and right on the upper crossbeam 1, thereby adjusting the width of the groove gap 4 to adapt to groove walls of different widths.
[0021] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
