Description
Technical Field
The utility model belongs to the technical field of building construction, and particularly relates to a lightweight combined support system of a space curved-surface reticulated shell.
Background
For the 21 st century, space curvature reticulated shell structures have been increasingly used in building construction design as the aesthetic demands of modern masses for urban building construction have increased. The steel structure has the advantages of light weight, high strength, easy plasticity and the like, and is often used as a core framework of a space curved-surface reticulated shell structure.
At present, in the installation process of a space curved-surface reticulated shell structure in steel structure engineering, a block hoisting method is generally adopted for installation operation according to factors such as structural modeling, structural unit type, structural height, site conditions, hoisting machinery and the like. The space curved surface net shell steel structure modeling adopts a block hoisting method to operate, and most space curved surface steel structures can only be selected to be erected into a scaffold or a steel lattice structure to serve as a vertical supporting system due to various reasons that the gravity center position and the centroid position are not coincident and the supporting point position is difficult to determine.
If the scaffold is used as a vertical support, all the block units are required to be supported, and when the curved net shell structure with larger structural size and curved radian is installed, the scaffold is used as the whole support at the lower part of the structure, and the construction period, the cost and the erection difficulty are larger. Meanwhile, the number of the vertical rods and the cross rods is greatly increased along with the increase of the erection height of the scaffold, so that the construction cost is further increased.
If the lattice type support frame is adopted as the vertical support, when the space curved surface net shell part structure is in a special configuration such as large perpendicularity, hyperboloid, small net shell gap size and the like, the lattice type support frame is not applicable due to the fact that the plane size of the lattice type support frame is limited and the space curved surface net shell structure collides with each other.
In summary, in the installation process of the steel structure engineering space curved-surface reticulated shell steel structure, the scaffold and the lattice type supporting frame are used as a conventional supporting system. The former is greatly increased with the complexity of configuration parameters such as structural size, curved surface radian and the like due to the construction difficulty, the manufacturing cost and the structural safety. Especially when space curved surface net shell steel construction skeleton height is great, the scaffold is because of its connection quality, the material quality of pipe fitting and buckle all very important to the structural strength influence of whole braced system, leads to controlling the degree of difficulty to the security great. The latter is not applicable because of the limit of the plane size and the collision of the space curved net shell structure when the space curved net shell structure is in a special configuration such as large verticality, hyperboloid, small net shell gap size and the like.
Therefore, the design of the light-weight combined support system for the space curved-surface reticulated shell has the characteristics of small space volume, simple stress, light weight and easy control of connection quality, and is used as a vertical support system in the installation process of the steel structure skeleton of the space curved-surface reticulated shell, so that the technical problem to be solved by the person skilled in the art is urgent.

And secondly, at the segment interfaces of the segmented units with different elevations of the space curved-surface reticulated shell, the H-shaped steel is used as the circumferential connection of round steel pipes, and the structural form of welding or binding steel springboards is adopted, so that the H-shaped steel can also be used as a manual operation platform.

If the space curved-surface reticulated shell structure is higher, the combined support system formed by welding round steel pipes, angle steel and H-shaped steel can be installed in a sectional manner in the height direction.
After the support system is formed, the H-shaped steel provides radial rigidity for the support system, and then the round steel pipe is connected in a circumferential manner at the joint of the round pipe support and the space curved surface net shell, so that the circumferential rigidity of the support system is provided and the support system is also used as a construction operation platform, as shown in fig. 7 and 8. The angle steel is used as a hand-pulling member, and the joint of the round tube is combined with the H-shaped steel to form omnidirectional constraint, so that the stability of the free section of the round tube is ensured.
(2) And (3) material parameter selection of a combined support system:
1) Selecting the sections of round steel pipes, H-shaped steel and angle steel: after finite element analysis of the combined support system, the cross section of the component is selected in combination with the selected safety factor.
2) The optimal free section length selection (the annular and radial support elevation spacing composed of H-shaped steel and angle steel) of the round steel pipe is calculated as follows (taking Q235 material as an example):
①②/>Q/>④F CR ＝F×K
lambda-compliance (61.6-100);
i-the radius of inertia (unit: cm) of the round steel tube to the neutral axis;
the value coefficient of the u-round tube under the constraint conditions of different ends is considered according to the hinging of two ends, and the value is 1;
F CR -vertical load (unit: N) to which the round steel pipe is subjected;
elastic modulus (unit: gpa) of E-Q235 material;
moment of inertia (unit: cm) of I-round steel tube to neutral axis 4 )；
L-length of free section of round steel tube (unit: mm);
the vertical load applied by the F-space curved-surface reticulated shell structure to the round steel pipe can be considered as the dead weight (unit: N) of the reticulated shell unit;
a-cross-sectional area of round steel pipe (unit: mm) 2 )
K is a safety coefficient.
Firstly, according to a formula (3), selecting round steel pipes with different section specifications, wherein the strength of the round steel pipes meets the requirements, from the existing materials. Then, the maximum free length L of the round steel pipe satisfying the stability condition is obtained by using the formula (2). And finally, bringing the maximum free length L of the circular tube in the formula (2) into the formula (1), and if the lambda value is larger than 61.6, meeting the requirement. If lambda is smaller than 61.6, the round steel pipe is a short thick rod piece, and stability checking calculation is not needed.
