Embodiment Construction

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] The overall structure of the covered bridge

[0043] The main bridge of the covered bridge is a 3-span continuous wooden beam bridge, which adopts the cross-glued wood consolidation system, and the span layout is (12+16+12)m. The upper structure is composed of the main load-bearing gallery system 600 and the bridge deck system. The corridor house system 600 is a piercing bucket structure, including a middle span with 5 double eaves pagoda style open room 603 , side spans with 5 double eaves pagoda style top rooms 602 and 6 double eaves connecting corridor style secondary rooms 604 . The colonnade 601 is built with several corridor beams and roof panels; the middle distance between the colonnade 601 along the span of the bridge is 4m, and the distance between the two ends is 1.5m; there are 4 horizontal pillars 601, of which the...

Abstract

The invention discloses a laminated wood gallery bridge which comprises at least two longitudinal beams, supports for supporting the longitudinal beams, a bridge panel and a gallery house system. Gallery columns of the gallery house system are arranged in the length direction of the longitudinal beams, cross beams are arranged at the positions of the supports and the gallery columns of the longitudinal beams, the two ends of each cross beam are fixedly connected with two adjacent longitudinal beams, the bridge panel is laid on a square formed by the cross beams and the longitudinal beams, thebridge panel is connected with the longitudinal beams in a laminated manner, the gallery columns are arranged on the bridge panel and fixedly connected with the longitudinal beams, and the longitudinal beams, the cross beams, the bridge panel and the gallery columns are all made of laminated wood. The laminated wood gallery bridge has the advantages of good integrity, small vibration and deformation, reduced section size, material conservation, cost reduction and the like.

Description

technical field [0001] The invention relates to a modern wooden structure bridge, in particular to a glued wood corridor bridge. Background technique [0002] The wooden covered bridge is a combined building of a corridor house and a bridge. Because the corridor house can shelter from wind and rain, the covered bridge is also called the wind and rain bridge. It has the characteristics of practicality, humanity and artistry. The modern wooden structure bridge adopts glued wood Instead of logs as the main material, it makes up for the shortcomings of ancient wooden bridges in terms of span, bearing and function. At the same time, with the development of my country's tourism industry, the improvement of traditional building protection needs and the support of industrial policies, modern wooden bridges and buildings have been vigorously researched and promoted. [0003] as attached figure 1 And attached figure 2 As shown, the glulam simply supported girder bridge has a span ...
