Invisible structure of anchor bar and application of invisible structure

Abstract

The invention provides an invisible structure of an anchor bar. The invisible structure includes a base and an anchor bar, wherein the anchor bar is a complete steel bar, and includes a first segmentand a second segment; the first segment and the second segment form an included angle of 90 degrees; and the second segment of the anchor bar is embedded in the base, and the first segment is close toone surface of the base. According to the invisible structure of the anchor bar, no holes are required to be formed in formworks during concrete pouring vertical formwork construction, and the disassembly and assembly of the formworks are very convenient, materials are saved, and safety and high efficiency are achieved.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to an anchor bar invisible structure and application thereof. Background technique [0002] With the rapid development of national infrastructure construction, investment in water conservancy and hydropower projects has also continued to increase, and a large number of hydropower, river hubs, farmland water conservancy, urban flood control, and water supply and drainage projects have been built to benefit and eliminate disasters, reduce disasters, and improve The water environment plays a huge role in promoting the sustainable development of economy and society. [0003] In the hydraulic building structure that needs to pour the second-stage concrete or install related embedded parts, the traditional construction technology is to first open a hole at a predetermined position on the formwork, then insert and bury the linear anchor bar and then pour the concrete. Formwork...

Problems solved by technology

This will bring about two problems. The first problem is that holes need to be drilled in the standard formwork, which is not conducive to the later use of the formwork; will damage the template

This complex and unfavorable situation is more common in the construction of gate slots. For example, in the construction of sluice pier, shaped steel formwork or shaped wooden formwork is generally used for installation. Anchoring steel bars with a diameter of about 18 to 20mm are pre-embedded on the front and inner sides (the design generally protrudes 30cm), and the anchoring steel bars are used to overlap with the second-stage concrete and gate rail; the traditional process needs to be pre-embedded in the formwork (design interval 0.5m) Drill holes and insert steel bars for reservation. The pre-embedded steel bars protrude about 10 to 30 cm outside the formwork. After the concrete gate groove is poured and tamped, the formwork is removed. ) in the two directions of the pre-buried (designed to protrude 30cm) anchor bars, which pass through the formwork and are anchored in the concrete. Therefore, when the formwork is removed, it is blocked by the embedded bars in the two directions of the concave steel formwork of the gate groove, and the formwork cannot be withdrawn. It is very different to cut the protruding steel bar short and withdraw it and then perform barge length welding, or shorten the length of the anchor bar protruding outside the formwork to 5 to 10 cm during pre-embedding, and then perform barge length welding after the formwork is removed. It is beneficial to formwork removal construction and greatly increases the workload. In addition, the original formwork will be damaged due to drilling. It is difficult to withdraw the formwork during formwork removal. Repeated formwork will be required, which will affect the construction progress and cost control. The holes in the perforation process will Lead to grout leakage, surface unevenness such as concrete pockmarks or honeycombs
