Steel pipe truss beam track type jig frame limiting, assembling and cluster jack unloading method

Abstract

The invention discloses a steel pipe truss beam track type jig frame limiting, assembling and cluster jack unloading method applied to the field of overhead, large-span heavy steel pipe truss beam construction. The technical problem that the national construction technology cannot be embezzled completely in a resource limiting region is solved. According to the technical scheme, the method comprises the following steps of 1, determining set-up parameters; 2, setting up a steel pipe scaffold system; 3, laying wood beams on a bearing frame and an operating frame to form a platform; 4, arranginga body protecting handrail and a slope; 5, arranging an H-shaped steel jig frame and a limiting device; 6, arranging a cluster jack; 7, lifting and conveying truss beam lower chord assembling rods tothe H-shaped steel jig frame four times separately; 8, fixing vertical web rods; 9, lifting and conveying upper chord combination rods to the portion above the vertical web rods four times separately;10, finally, synchronously unloading the jack. The method has the advantages of being convenient to use, rapid, safe, economical and practical, and has the remarkable application and popularization value in the resource limited region.

Description

technical field [0001] The invention relates to the technical field of truss beam construction, more specifically, it relates to a steel pipe truss beam track-type tire frame limit assembly and cluster jack unloading construction method. Background technique [0002] China is a developing country. Over the years, while committed to its own development, China has always insisted on providing assistance within its capacity to other developing countries with economic difficulties and undertaking corresponding international obligations. China's foreign aid projects are mainly distributed in fields such as agriculture, industry, economic infrastructure, public facilities, education, and medical care. In recent years, with the continuous enhancement of China's comprehensive national strength, the construction technology level of foreign aid projects has also been continuously developed, especially in China's track construction, building construction and other foreign aid projects...

Problems solved by technology

[0004] Domestic large-span construction technology is becoming more and more perfect. Given that recipient countries are generally backward, with weak industrial foundations and limited resources such as engineering materials, mechanical equipment, and construction turnover materials, domestic construction technologies cannot be fully applied to recipient countries. China; we try to make steel pipes into several prefabricated components in China, and then transport them to recipient countries for assembly; but the installation of steel pipe truss beams is a one-time construction process, such as making heavy temporary support columns in China and sending them by sea , the cost is obviously too high, which violates economic laws, so technical research and development of suitable construction techniques are required
