Description

Technical Field

[0001] This utility model relates to the field of building and transportation municipal engineering technology, specifically to an internal support device for reinforced concrete component formwork. Background Technology

[0002] With the continuous development of my country's construction, transportation, and municipal engineering, the requirements for construction technology and engineering quality are becoming increasingly stringent. To ensure the cross-sectional dimensions of vertical members in reinforced concrete structures, the traditional construction method involves installing mortar or steel reinforcement strips inside the formwork during formwork installation and reinforcement. Generally, the length of mortar reinforcement strips is 300mm or less. For concrete members wider than 300mm, mortar reinforcement strips are very prone to breakage during formwork reinforcement, failing to meet the requirements for internal support. If steel reinforcement is used directly as reinforcement strips, the exposed steel ends on the concrete surface after demolding must be treated to prevent rusting, which is both labor-intensive and material-intensive, and also affects the appearance quality of the concrete surface.

[0003] For concrete members wider than 300mm, how to effectively ensure the width of the concrete cross-section while effectively compensating for the insufficient exposure of the steel bar ends caused by the use of traditional steel bar internal bracing? This paper studies a utility model of an internal support device and construction method for wide-section reinforced concrete member formwork. Based on traditional construction methods, this paper innovates and puts forward higher requirements and more refined research directions for our design and construction technicians.

[0006] The connecting assembly includes a pad, a plate, a long rod, and a sleeve;

[0007] The pad is placed on the template, the pad has the pad plate, the pad plate has the extension rod, the pad plate is used to connect the pad and the extension rod, and the extension rod has the sleeve.

[0008] The sleeve is provided with a connecting rod, which is used to extend the support device.

[0009] Preferably, both the extension rod and the connecting rod have connecting grooves.

[0010] Preferably, the sleeve is hollow, and the connecting groove is formed in the sleeve.

[0011] Preferably, the connecting grooves on the sleeve engage with the connecting grooves on the extension rod and the connecting rod.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This internal support device for reinforced concrete component formwork, through its combination of "connecting rods + pads" and adjustable internal support, allows for precise adjustment and effective control of the geometric dimensions within the formwork cross-section during the installation and reinforcement of wide-section reinforced concrete component formwork support systems. While ensuring the cross-sectional dimensions of wide-section concrete components, it avoids the problem of exposed rebar ends requiring rust treatment after demolding, as is common in traditional construction methods using internal rebar struts. This ensures project quality, improves construction efficiency, and saves on aesthetic quality treatment costs. Furthermore, this combination of "rebar + concrete pads" and adjustable internal support device can be mass-produced in a factory or prefabricated on-site, saving manufacturing costs and construction time.

[0023] like Figure 1-2 As shown, this utility model provides a technical solution: an internal support device for reinforced concrete component formwork. The support device is installed in the formwork 8, which is enclosed in a rectangle. The inner side is used for pouring concrete 7. It includes a connecting component, which includes a pad 1, a pad plate 2, a long rod 3, and a sleeve 6. The pad 1 is installed on the formwork 8. The pad 1 is made of the poured concrete 7, with a diameter of 50 mm and a thickness of 50 mm. The pad 1 has a pad plate 2 with a diameter of 30 mm and a thickness of 4 mm. The pad plate 2 is made of steel plate. The pad plate 2 has an extension rod 3 with a diameter of 20 mm and a length of 120 mm. One end of the extension rod 3 is welded to the pad plate 2 to form a T-shape, and the other end is machined with a 30 mm straight thread connection head, which is the connecting thread 4. The pad plate 2 is used to connect the pad 1 and the extension rod 3. The extension rod 3 has a sleeve 6, which is a Φ20 steel bar straight thread connection sleeve 6.
