Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0021] see Figure 1-2 , a method for installing large-size purlins on a large-span special-shaped roof, comprising the following steps: installing a hoisting device on a roof beam; An angle steel is added to the support, so that the large-scale purlins are hoisted and placed between the angle steels between the supports through the above-mentioned hoisting device, and fixed with the above-mentioned roof beams.
[0022] In the present invention, the above-men...

The invention relates to the technical field of architectural engineering design and construction, and discloses a method for installing large-size purlins on a large-span special-shaped roof, comprising the following steps: installing a hoisting device on a roof beam, and when installing and positioning the roof purlins, First fix the support to the main steel structure, and then add an angle steel to the support, so that the large-sized purlins are hoisted and placed between the angle steels between the supports through the above-mentioned hoisting device, and fixed to the above-mentioned roof beams. The large-size purlin installation method and construction technology on the long-span special-shaped roof can make the keel installation accuracy reach the millimeter level and the installation speed can be rapidly increased under the premise of ensuring safety, and has good economic effect and use value.
Description
technical field [0001] The invention relates to the technical field of architectural engineering design and construction, in particular to a method for installing large-size purlins on a large-span special-shaped roof and a construction process. Background technique [0002] At present, a large number of special-shaped buildings have been newly built in China. Most of the main structures of these special-shaped buildings are in the form of long-span steel trusses, pipe trusses or net frames. If it is more than ten meters, the span of the roof purlin should be increased accordingly. The increase of the span will increase the section of the purlin (keel), and the weight per unit meter will increase, which will bring inconvenience to the installation of the purlin, especially when the installation requirements of the keel are high. In order not to affect the installation of the decorative layer (aluminum plate, glass), the accuracy of the purlins has reached the millimeter leve...
