specific Embodiment approach 1

[0047] Specific implementation mode one: combine Figure 1 to Figure 5 Specifically explaining this embodiment, a method for calculating the roof system of a double-centered elliptical speed skating hall based on the principle of Kaiwitt grid layout described in this embodiment is carried out in accordance with the following steps:

[0048] 1. Standardized design of plane grid system:

[0049] According to the size of the transverse axis of the site, determine the center of the circle O 1 , center O 2 and radius r 1 , take the transverse axis as the axis of symmetry, and take the center O 1 as the center of the circle, with r 1 Draws an elliptical arc with an angle of 135° for the radius center O 2 as the center of the circle, with r 1 Draws an elliptical arc with an angle of 135° for the radius The arc of the ellipse with elliptical arc The opening direction is relatively arranged; and the above-mentioned A 1 with A 4 On the same side of the transverse axis, A...

specific Embodiment approach 2

[0070] Embodiment 2: This embodiment differs from Embodiment 1 in that: the standard prestressed tension string beam is 48 standard prestressed tension string beams. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0071] Specific implementation mode three: combination Figure 6 to Figure 11 Describe this embodiment in detail, the construction method of the double-centered elliptical speed skating hall roof system described in this embodiment is carried out according to the following steps:

[0072] 1. Assemble the shuttle ring truss at the center of the ground site;

[0073] The shuttle-shaped ring truss is a double-layer truss structure composed of a ring truss and a shuttle-shaped truss;

[0074] 2. Install the lower chords and struts in a low-level ring direction;

[0075] 3. Apply prestress through the lower strings, then lift the shuttle ring truss as a whole, and simultaneously lift the lower strings and struts;

[0076] 4. After the shuttle-shaped ring truss, lower chord cables and struts are lifted into place, install the circumferential rods and radial rods;

[0077] The hoop rods, radial rods, lower strings and struts constitute standard prestressed string beams;

[0078] ...

Abstract

Disclosed are a method for calculating a double-hearted elliptical speed skating roof cover system based on a Kiewitt grid layout principle and a construction method. The invention relates to the method for calculating the double-hearted elliptical speed skating roof cover system and the construction method, and aims at solving the problems of complex structural component layout, low component standardized degree, large processing amount and high construction difficulty in the prior art. The calculation method comprises the steps of step 1, standardized design of a plane grid system; step 2, generation of basic projection lines; step 3, generation of a circumferential network; step 4, generation of combined grids; step 5, generation of a structural grid system. The construction method comprises the steps that assembly of a fusiform circular truss is conducted at a ground site center; circumferential installation at lowered positions of lower cables and supporting rods is conducted; prestressing force is exerted through the lower cables, overall elevation of the fusiform circular truss is conducted, and elevation of the lower cables and the supporting rods is conducted synchronously; after the fusiform circular truss, the lower cables and the supporting rods are elevated in place, and circumferential rod members and longitudinal rod members are installed; outer circular steel beams are installed and reinforcement of the overall structure is completed; a roof grid structure is installed.

Description

technical field [0001] The invention relates to a method for calculating the roof system of a double-center elliptical speed skating hall and a construction method. Background technique [0002] With the successful declaration of the 2022 Winter Olympics, ice and snow sports are gradually gaining a dominant position in the field of national fitness, and the upsurge of building ice and snow sports venues across the country is one after another. Among them, the Boulevard Speed ​​Skating Hall is an important type of building facility with a wide range of uses and strong capacity among ice and snow sports venues, and has broad development prospects. Because of its complex architectural shape, irregular plane, and huge space span, relatively strict quality requirements and strength standards are given in the building code. In order to ensure the structural safety and beautiful appearance of the building, the roof of the existing avenue speed skating hall mostly adopts the reticu...
