Abstract
The invention relates to the field of net rack installation, in particular to a construction method for assisting a reticulated shell structure to avoid secondary starting at an expansion joint. The invention directly solves the problem of secondary starting and hoisting of the grid structure at the expansion joint, reduces the construction difficulty, improves the construction efficiency and reduces the construction cost.
Description
Technical Field
The invention relates to the field of net rack installation, in particular to a construction method for assisting a net shell structure to avoid secondary starting at an expansion joint.
Background
The square quadrangular pyramid bolt ball grid structure belongs to a high-order hyperstatic structure system and is a space structure formed by connecting a plurality of rod pieces through nodes according to a certain grid form. The space truss structure can be divided into gable starting and intermediate span starting according to the starting span position, and no matter which type of starting span method, the space truss structure for setting up the expansion joint all needs to disconnect the rod piece at the expansion joint position, and the hoisting is striden in the starting that leads to needing the secondary, and the secondary starting is striden the hoist and mount and is caused construction cost to increase, influences construction period moreover.
Disclosure of Invention
In order to solve the technical problem, the invention provides a construction method for avoiding secondary starting and hoisting, which has high construction efficiency and can be used for assisting the reticulated shell structure to avoid secondary starting at the expansion joint.
The invention adopts the following technical scheme:
a construction method for assisting a latticed shell structure to avoid secondary starting at an expansion joint comprises the following steps:
A. selecting a common net shell splicing rod piece as a transition rod piece, wherein two ends of the transition rod piece are respectively provided with a high-strength bolt and a nut;
B. dividing the latticed shell structure into a plurality of areas, connecting the bolt balls of the first area and the second area on two sides of the expansion joint by using a transition rod piece after the starting installation of the first area is finished, and taking the bolt balls of the first area positioned at the edge of the expansion joint as starting;
C. after all the rods in the second area are installed, dismantling the transition rods between the first area and the second area;
D. and D, repeating the steps A to C, and assembling the rod pieces in the rest areas.
Compared with the prior art, the invention has the beneficial effects that:
the invention directly utilizes the transition rod piece as temporary fixed connection to temporarily form the net racks at two sides of the expansion joint into a whole, thereby reducing the secondary starting and installation procedure of the net rack structure at the expansion joint, improving the construction efficiency and reducing the operation difficulty; and the transition rod piece can be used in a turnover way, and the operation is convenient.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a diagram illustrating the effect of the present invention after splicing;
in the figure: a transition bar member 1; a bolt ball 2; an expansion joint 3.
Detailed Description
The invention is further described below with reference to the accompanying drawings and specific embodiments.
A construction method for assisting a latticed shell structure to avoid secondary starting at an expansion joint comprises the following steps:
A. select ordinary net shell concatenation member as transition member 1, the both ends of transition member 1 are provided with the bolt and the nut of high strength respectively, and the bolt and the nut at 1 both ends of transition member need satisfy: the nut is rotated in the forward direction, the high-strength screw rod can enter the bolt ball 2 holes, the nut is rotated in the reverse direction, and the high-strength screw rod exits the bolt ball 2.
B. The latticed shell structure is divided into installation areas such as a first area, a second area, a third area and the like according to the number of expansion joints 3, the first area is normally started and installed, after all rod pieces in the first area are installed, bolt balls 2 on two sides of the expansion joints 3 (namely the bolt balls 2 on the edge of the first area and the bolt balls 2 on the starting end of the second area) are connected through transition rod pieces 1, and the edge of the first area located at the expansion joints 3 serves as the starting of the second area.
C. After all the rods in the second area are installed, the transition rods 1 between the first area and the second area are removed.
D. And D, repeating the steps A to C, and assembling the rod pieces in the rest areas.
In actual construction operation, the method directly solves the problem of secondary starting and hoisting of the grid structure at the expansion joint, and the transition rod piece 1 is used as temporary connection between adjacent installation areas to temporarily form the grids on two sides of the expansion joint 3 into a whole, so that construction steps are reduced, construction difficulty is reduced, construction efficiency is improved, and construction cost is reduced.
The above description is only for the specific embodiment of the present invention, but the protection of the present invention is not limited thereto, and all equivalent changes or substitutions to the technical features of the present invention that can be made by those skilled in the art are included in the protection scope of the present invention.
