Embodiment Construction
[0024] 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.
[0025] A construction method for a canopy canopy, comprising the following steps:
[0026] S1, first measure the pre-embedded points of each anchor bolt, encrypt the axis and elevation control points on the site according to the original axis control point and elevation control point, and then measure and release each embedded part according to the axis measured and released by the control line and at least two elevation control points;
[0027] The embedded ...

The invention provides a construction method of an overhanging awning. The method comprises the following steps: S1, performing pre-embedded construction of sill anchors; S2, hoisting stiff steel columns; S3, dividing hoisting of roof main trusses into twenty four mounting units; S4, performing supporting mounting of a first section of a main truss; S5, firstly constructing a hoisting section I when a section of a main truss GHJ1 is mounted; S6, hosting an inclined stand column, hoisting the other end through a crane, and then hoisting a front end hoisting section II or the next main truss; S7, performing supporting mounting and main truss mounting according to the steps S4 to S6, so as to form a first mounting unit; S8, tying rods between two main trusses and mounting secondary trusses, and adopting high-altitude connection for a secondary truss between each two main trusses; S9, accomplishing the other twenty three mounting uses through circulation of the steps S4 to S7. The method solves the problems of large span of trusses, long components and high construction difficulty during the construction of the traditional overhanging awning by mounting the trusses section by section in a region, meanwhile increases temporary supports, and improves the lateral stability of single truss.
Description
technical field [0001] The invention relates to the technical field of cantilevered canopy construction, in particular to a cantilevered canopy construction method. Background technique [0002] In recent years, with the continuous development of domestic sports, the number of domestic stadiums has increased significantly. The main body of the structural system of traditional stadiums is a concrete frame structure, and the roof is a cantilevered space truss grid structure. However, during the roof installation process, due to the main truss The components are long, some truss sections are too large, transportation is difficult, the whole construction is difficult, and the construction period is long, the stadium area has a large span, heavy quality, and limited operating conditions. The cantilevered span of the single truss is large. The lateral stability is poor, and it is easy to deviate during the construction process, which affects the progress of the subsequent process....
