Description

Technical Field

[0001] The invention relates to the technical field of construction and traffic municipal engineering, and in particular to a reinforced concrete component template internal support device and a construction method. Background Art

[0002] With the continuous development of my country's construction and transportation municipal engineering, the requirements for construction technology and engineering quality are becoming higher and higher. In order to ensure the cross-sectional dimensions of the vertical components of reinforced concrete structures, the traditional construction method is to set mortar internal supports or steel internal supports in the formwork when the formwork is installed and reinforced. Generally, the length of the mortar internal support is 300mm or less. For concrete components wider than 300mm, the mortar internal support is very easy to break during the formwork reinforcement process and cannot meet the internal support requirements; if steel bars are directly used as internal supports, the steel bar heads will be exposed on the concrete surface after the formwork is removed and must be treated to prevent rust, which not only wastes labor and materials, but also affects the visual quality of the concrete surface.

[0003] For concrete components with a width greater than 300mm, how to effectively ensure the width of the concrete section while effectively compensating for the insufficient exposure of the steel bar head caused by the use of traditional steel bar internal supports? We have studied and invented an internal support device and construction method for wide-section reinforced concrete component templates, which innovates on the basis of traditional construction methods and puts forward higher requirements and detailed research directions for our design and construction technicians. Summary of the invention

[0004] The purpose of the present invention is to provide a reinforced concrete member template internal support device to solve the problems raised in the above background technology.

[0011] Preferably, the connecting lines on the sleeve are engaged with the connecting lines provided on the extension rod and the connecting rod.

[0012] Preferably, the connecting components are at least two groups, and all the connecting components are arranged on the connecting rod.

[0013] A construction method for a reinforced concrete component template internal support device, the steps comprising:

[0014] Processing the connection assembly, connecting the pad and the long rod, providing connection lines on the long rod and the connection rod, and arranging the pad in the pad block;

[0017] Preferably, after the supporting device is arranged on the template, the cross-sectional dimensions of the template are accurately corrected, and the correction sleeve, the long rod and the connecting rod are rotated to extend the length of the long rod and the connecting rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the reinforced concrete component formwork internal support device, through the combined fine-adjustable formwork internal support device of "connecting rod + pad", can accurately adjust and effectively control the geometric dimensions of the formwork cross section when the wide-section reinforced concrete component formwork support system is installed and reinforced. While ensuring the cross-sectional dimensions of the wide-section concrete component, it avoids the problem of the exposed steel bar heads that need to be treated for rust after the traditional construction uses steel bar internal support rods to remove the formwork, which not only ensures the quality of the project, but also improves the construction efficiency and saves the cost of visual quality processing. In addition, the combined fine-adjustable formwork internal support device of "rebar + concrete pad" of the present invention can be mass-produced in a factory or prefabricated in advance at the construction site, which can save manufacturing costs and construction time.
