A kind of construction method of modern bamboo pedestrian truss bridge

Abstract

The invention discloses a construction method for a modern bamboo pedestrian truss bridge. A truss bridge structure comprises a pairs of bridge piers, two columns of erection supports and a main truss, wherein the bridge piers are made of concrete; the erection supports are fixed on the bridge piers and made of steel materials; the main truss is connected to the erection supports and composed of ball node elements and connecting rods, the ball node elements are made of the steel materials, and the connecting rods are made of heavy bamboo materials. The truss bridge structure further comprises a bridge deck slab and handrails, and the bridge deck slab and the handrails are made of the heavy bamboo materials. The construction method is characterized by comprising the steps of element prefabricating, preassembling, bridge pier forming by cast-in-place, full framing constructing to complete bridge body installation and waterproof paint painting. The construction method for the modern bamboo pedestrian truss bridge has the advantages that the element connection is convenient, the construction is simple and fast, the modulization production is facilitated, the bridge weight is light, the anti-seismic property is good, and nodes are stable and reliable; therefore the obtained pedestrian truss bridge has the advantages of being green, low carbon, environment-friendly and economical, and the requirements of the normal use and the durability of a bridge structure are met.

Description

technical field [0001] The invention relates to the technical field of bridge structures, in particular to a construction method for an assembled modern bamboo pedestrian truss bridge suitable for modern pedestrians and landscapes. Background technique [0002] Recombined bamboo, also known as heavy bamboo, is a new bamboo material that reorganizes and strengthens bamboo. A profile made of blanks and pressure glued together. It has the advantages of low density, high strength, good toughness and good shock resistance. Under the background of the major theme of "sustainable development" in today's international society, "recombined bamboo" has become a modern and new green building material that replaces high-pollution and high-energy-consuming materials such as steel and concrete. my country is very rich in bamboo resources, known as the "Second Forest", and is the main bamboo-producing country in the world. Applying bamboo, a natural resource, to civil engineering, as th...

Problems solved by technology

The bridge body of the truss bridge is composed of connecting rods, which can convert the bearing capacity into the tensile pressure of the connecting rods, but its construction is generally more complicated, and the construction technology requirements are higher, so it is generally used in large-span bridges such as cross-river bridges. local use
