Embodiment 1

[0043] Embodiment one: the preferred embodiment of the present invention is described in detail as follows in conjunction with accompanying drawing: as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, the construction technology of the reinforced concrete special-shaped cylinder group structure with variable curved surface in this space is constructed in sections from bottom to top, and the construction steps of each section are as follows:

[0044] a. According to the design drawings, the numerical axis and letter axis control axis of the horizontal plane of the entire special-shaped cylinder group and the planar grid positioning template 1 of the various shaped cylinders obtained after the offset of the digital axis and the letter axis control axis at the construction site Position the X', Y' axes for measurement and positioning; the plane grid positioning template 1 is: according to the positioning curve diagram provided by the designer for determining...

Embodiment 2

[0054] Embodiment two: this embodiment is the same as embodiment one, and the special feature is that the detailed method of each construction step is as follows: said step 1) controls the axis of the digital axis and the letter axis of the horizontal plane of the whole special-shaped cylinder group at the construction site according to the design drawings And the specific construction steps for measuring and positioning the X' and Y' axes of the plane grid positioning template 1 of various shaped cylinders obtained after the axis offset is controlled by the number axis and the letter axis are as follows: According to the special-shaped cylinder provided by the designer Figure axis, letter axis control axis diagram, use the number axis and letter axis control axis orthogonal to the center of each special-shaped cylinder as the positioning X', Y' axis of the plane grid positioning template 1 of each special-shaped cylinder; If no axis passes through the special-shaped cylinder, ...

Embodiment 3

[0064] Embodiment three: the present embodiment is basically the same as embodiment one, and the special feature is that the steps are as follows:

[0065]①Because the special-shaped cylinder (beam) is in the form of a curved surface, it is impossible to determine the plane layout and positioning of the structure at a specific height in AutoCAD, so it is the first time to borrow high-tech application software such as CATIA and AutoCAD for secondary development. Use the 3D geometric model established by CATIA to generate the plane, elevation, and section slices of the overall structure, and output the axis positioning diagram of the special-shaped cylinder structure in DWG format. According to the positioning axis diagram of the special-shaped cylinder structure, the orthogonal number axis and letter axis passing through the center of each special-shaped cylinder are used as the positioning X' and Y' axes of the plane grid positioning template; The cylinder shifts the control a...

Abstract

The invention relates to a construction technology of spatial variable curved surface reinforced concrete irregular barrel group structure, comprising some bottom-up segments constructed one by one according to the design drawing of each segment; and each segment comprises the following construction steps: 1), measuring and positioning the positioning X', Y' axes of the digital axis and letter axis control axis of the whole irregular barrel group horizontal plane and the planar grid positioning template of each regular barrel obtained after the digital axis and letter axis control axis is offset according to the design drawing; 2), manufacturing the planar grid positioning template; 3), setting up the support steel pipe bent frame of an irregular barrel outer mold; 4), mounting the planar grid positioning template; 5), carrying out altitudinal measurement and positioning of planar grid positioning template of each irregular barrel and checking the positioning X', Y' axes; 6), constructing the irregular barrel outer mold; 7), constructing the irregular barrel steel pipe; 8), setting up the support steel pipe bent frame of an irregular barrel inner mold; 9), constructing the irregular barrel inner mold; 10), constructing irregular barrel reinforced concrete. The construction technology breaks up the whole into parts and congregates parts to become the whole, and the segments of the irregular barrel group are constructed one by one; both the construction materials and the construction tools are universal and easy to construct.

Description

technical field [0001] The invention relates to a construction technology of a reinforced concrete special-shaped cylinder group structure with variable space and curved surfaces for industrial and civil buildings. Background technique [0002] In modern urban construction, buildings with unique shapes are more and more widely used, bringing vitality to the urban landscape. The unique shapes of the "Bird's Nest" and "Water Cube" buildings of the Beijing Olympic Games have added new brilliance and honor to our country, and also marked the continuous improvement of our country's architectural level. The carrier of this patent application—Shanghai Zendai Himalayas Art Center is another example of a building with unique appearance in my country. architectural image. [0003] The special-shaped reinforced concrete cylinder group structure with variable space and curved surface has unique architectural shape and strange shape. This kind of architectural structure has not been rep...
