Ming dynasty-style building concrete bucket-arch piece pre prefabricated construction technique

Abstract

The invention discloses a presetting, installing and constructing techniques for concrete separate pieces of Chinese peck and arch of Ming and Qing Dynasties imitation buildings. The techniques comprises the following steps: firstly, the molds of the Chinese peck and arch are made, each single component is lofted, the mold sample for each single component, the real object sample for each single component and the mold for each single component are manufactured in mass and the real object for each single component is preset in mass, and the single components are connected into 1 / 2 pavilion of Chinese peck and arch by using the raised concrete in the Chinese peck and arch system in different categories, the Chinese peck and arch which are connected into 1 / 2 pavilion are repaired in details, the 1 / 2 pavilion of Chinese peck and arch can be lifted to the right position after the aging is reached, the internal and external 1 / 2 pavilion of Chinese pecks and arches are all lifted to the right position, the Chinese peck and arch reserved reinforced steel bar is soldered with the reinforced steel bar for padding an arch plate, then the concrete for padding the arch plate is constructed, thus forming the integrated Chinese peck and arch system. By adopting the process, the construction quality and the production efficiency can be increased, and the installing difficulty can be reduced.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a prefabricated and installed construction technology for imitating Ming and Qing architectural concrete bucket arch subsections. Background technique [0002] In the publication (announcement) number: CN1364684 patent document, discloses a kind of anti-true Ming and Qing ancient building component prefabrication production method, this method first makes the basic physical component of ancient architectural wooden component; Turn over the mold, and select the appropriate concrete grade and reinforcement ratio, and use the obtained mold to prefabricate the components; finally, select the prefabricated components for the ancient buildings to be built according to the needs, and then hoist the prefabricated components for splicing and butt welding, and butt welding Some cast-in-place concrete. However, the shortcomings of this production method are: 1. It is necessary to make the ...

AI Technical Summary

Problems solved by technology

However, the shortcomings of this production method are: 1. It is necessary to make the basic physical components of the wooden components of the ancient buildings. In the Ming and Qing Dynasties, the size of the mouth is small and the relationship is close. It is quite difficult to make

2. The installation adopts the method of welding, which needs to reserve steel plates or steel bars on the components, and the quality of welding will affect the safety of the overall components, and it is difficult to control the construction quality. 3. After hoisting the components in place, butt welding When working at heights, the work efficiency is low, and the probability of construction errors is greatly increased. It is difficult to accurately correct the position of each component, and it will consume a lot of manpower and material resources.
