Steel bar connection device and using method thereof

Abstract

The invention belongs to the technical field of civil engineering, and particularly relates to a steel bar connection device and a using method thereof. The steel bar connection device is used for making a first steel bar connected with a second steel bar, and comprises an eccentric adjusting device, a steel bar connecting piece and an eccentric adjusting device mounting device. The eccentric adjusting device mounting device is arranged on at least one of the first steel bar and the second steel bar. The eccentric adjusting device is mounted on the eccentric adjusting device mounting device. Asliding groove is formed in the eccentric adjusting device, the sliding groove is perpendicular to the extending direction of the steel bars, the steel bar connecting piece is parallel to the extending direction of the steel bars, one end of the steel bar connecting piece is clamped to the sliding groove, and the other end of the steel bar connecting piece is connected with the other steel bar. The steel bar connecting piece slides in the sliding groove under the condition of being kept parallel to the steel bars, so that the eccentric adjusting device rotates. According to the device, the tolerance range is effectively expanded, reasonable deviations caused by production manufacturing, construction installation and the like are satisfied, and the eccentric angle and eccentric distance ofeccentric errors can be adjusted.

Description

Technical field [0001] The invention belongs to the technical field of civil engineering, and specifically relates to a steel bar connecting device and a use method thereof. Background technique [0002] Under the background of the country's vigorous development of prefabricated buildings, the status of precast concrete components in prefabricated buildings is also constantly improving. However, due to the complex construction site environment, insufficient component production accuracy, and the technical proficiency of on-site construction personnel, it is difficult to control the product quality of prefabricated components and the installation and construction progress, which leads to an increase in the overall cost of prefabricated buildings. .

Problems solved by technology

However, due to factors such as the complex construction site environment, insufficient component manufacturing accuracy, and the technical proficiency of on-site construction personnel, it is difficult to control the product quality and installation progress of prefabricated prefabricated components, which leads to an increase in the overall cost of prefabricated buildings.

[0003] The existing connection methods of prefabricated components mainly have the following problems: 1. The traditional wet connection, the post-poured concrete area is large, the amount of on-site pouring is large, and the anchoring steel bars in the node area are many and complicated, and there is difficulty in concrete pouring, which seriously affects the prefabricated building. The overall structural quality and safety of the structure; 2. Sleeve grouting connection, there are problems such as insufficient grouting, difficulty in aligning steel bars, blocking of grouting holes and high cost; 3. Dry connection such as bolts, there is connection strength Weak, high requirements for component manufacturing precision, construction site installation precision, and construction personnel's technical level

This patent still has the following problems: (1), its eccentric spacing is fixed and cannot be adjusted, and cannot be applied to the requirements of different eccentric spacings; (2), the eccentric angle is fixed, and cannot adapt to different angles of eccentricity; Many, affecting the installation efficiency of connecting devices
