A support device for repairing and protecting a wooden gallery bridge

Abstract

The invention discloses a support device for repairing and protecting wooden gallery bridges, including columns, a support base and a beam; the columns are arranged on the support base;the beam is arranged between the columns, the top of the column is provided with a U-shaped fixing seat, a support plate is movably connectedto that U-shaped fixing seat, both sides of the support base are movably connected with tie rods, one end of the tie rod is provided with a U-shaped support, The side surface of the U-shaped support is provided with a transverse groove, a longitudinal groove and a transverse through groove, the longitudinal groove communicates with the transverse through groove and the transverse through groove, a vertical plate is arranged on the cross beam, an elastic telescopic rod is movably connected with the vertical plate, a positioning pin is symmetrically distributed at one end of the elastic telescopic rod, the positioning pin is located in the transverse through groove, and the positioning pin is matched with the longitudinal groove and the transverse through groove. The invention has the advantages of stable structure, flexible connection, on-site flexible assembly,low construction difficulty, strong supporting performance and long service life.

Description

technical field [0001] The invention belongs to the field of wooden corridor bridges, and in particular relates to a support device for repairing and protecting wooden corridor bridges. Background technique [0002] The corridor bridge is beautiful in shape, integrating mountains, water, houses and bridges. It is not only beautiful and practical, but also has a profound cultural origin of ancient architecture. The top beams and bucket arches of the covered bridge are carved with various auspicious patterns, with exquisite craftsmanship and high appreciation value. Now the wooden covered bridge has become one of the main attractions to attract tourists from all over the world, and its safety must be highly valued. The wooden corridor bridge is mainly a wooden frame structure, that is, wooden columns and beams are used to form the frame, and the weight of the roof is transmitted to the columns through the beam frame. Under natural or natural action, it is easy to cause joint...

AI Technical Summary

Problems solved by technology

The wooden corridor bridge is mainly a wooden frame structure, that is, wooden columns and wooden beams are used to form the frame, and the weight of the roof is transmitted to the columns through the beam frame. It is easy to cause joint displacement, loosening and tenoning, or even breakage under natural or natural action, causing the wooden corridor bridge to skew or collapse, so regular repairs and protection are required

[0003] The support devices used for the restoration and protection of wooden corridor bridges in the prior art have the following problems: 1. The structure is relatively simple, which can only play a temporary support role, and the support performance is weak, which is useless; 2. Although it is connected as a whole, the integrity is good. However, it is inconvenient to disassemble and replace separately after partial damage. Once the whole body is dismantled, the rest will be implicated, resulting in poor overall stability and shortened service life.
