Embodiment Construction

[0029]First, carry out structural design. Calculate the load according to the national standard of the People's Republic of China "Code for Building Structure Loads" (GB50009-2001). According to the two-way plate load calculation method, the load on each space arch is transferred to the rib. The average line load along the rib axis can be approximated for internal force calculation, and the static load and live load are calculated separately and then combined. The internal force is calculated according to the existing calculation method for the internal force of the rib beam of the reinforced concrete well-shaped floor. It is recommended to give priority to the linear elastic calculation method, and it is not suitable to use the method of plastic internal force redistribution. It can be assumed that the steel reinforced concrete rib of the present invention has a double T-shaped calculation section. In the calculation, the effect of the steel wire mesh in the tension area an...

Abstract

The invention is a small-thickness steel framework concrete dense sandwich stringboard belonging to a new technique applied to structure of field cast concrete stringboard of civil engineering. The structure of the stringboard includes that the bottom layer is the first layer of cast fine stone concrete, in the middle of which is a steel-rib bottom-surface steel wire net, the top layer is the second layer of cast concrete, in the middle of which is a steel-rib top-surface steel wire net, there are 'well' of Chinese characters-shaped steel framework dense ribs arranged between the two steel wire nets; there is a decorated board of top and bottom wing edges arranged between the dense rib, the bottom-surface steel wire net and the top-surface steel wire net; there is an arc-sectional lightweight multi-porous material-containing core packet arranged on the first layer of cast fine stone concrete between two dense ribs, and there is a mortar heel block between the core packet and the top-surface steel wire net.

Description

technical field [0001] The invention is a new technology applied to the cast-in-place concrete floor structure of civil engineering, and belongs to the field of structural design and construction of civil engineering. Background technique [0002] The National Regulations (CECE175: 2004) "Technical Regulations for Cast-in-situ Concrete Hollow Floor Structures" has been published and implemented by China Planning Press. In July 2005, China held the first national technical seminar on cast-in-place concrete hollow floors at Tongji University in Shanghai. . On the 8th floor of Zhongshan International Building, Wuyi Square, Changsha City, Hunan Province, Qiu Zeyou of Changsha Juxing Lightweight Building Materials Co., Ltd. applied for a national invention patent on 2000.07.18 "Steel reinforced concrete cast-in-place hollow floor and its construction method" (application number 00113551.1), Approval. The main content of the patent is: "The present invention is a steel reinforce...
