Background
In recent years, large-span steel structures have been widely used in public construction. In order to meet the standard requirements of lighting, ventilation, smoke discharging and other functions, a large-scale skylight is often required to be arranged at the top of a public building. In practice, the skylight design is generally put into curtain wall professions or roof professions, a specific skylight structural form and a construction process are not generally considered in the design of a main steel structure, and therefore the adjacent roof systems can be damaged in the construction of the skylight in the later period, and the normal use of the roof systems is seriously affected.
Disclosure of Invention
Aiming at the defects existing in the prior art, the invention provides a construction method of a skylight fixing frame.
The construction method of the skylight fixing frame provided by the invention comprises the following steps:
(S1) splicing steel materials on the ground to obtain gantry sections, wherein each gantry section at least comprises two trusses, each portal comprises a transverse keel at the top and longitudinal keels at two sides, and two adjacent trusses are connected through a group of connecting keels;
(S2) installing lugs at the bottoms of two sides of the portal frame, wherein the lugs are arranged on the longitudinal keels;
(S3) erecting a pair of parallel sliding rails (31) on the roof according to the installation position of the skylight fixing frame;
(S4) hoisting the gantry sections to the roof section by section so that the lugs are pressed on the sliding rails;
(S5) using a traction device to draw the gantry segments section by section to the installation location;
(S6) fixing the gantry segment on the roof, in particular fixing the anchoring point at the lower part of the longitudinal keel with the corresponding anchoring point on the roof; then installing connection keels between adjacent gantry segments to obtain an installed skylight fixing frame;
and (S7) removing the sliding rail and the lugs.
Further, in step (S4), the lugs are preferably cross bars detachably fixed to the bottom of the longitudinal joists and extending outward of the portal frame.
Further, because a certain error often exists between the actual size of the roof and the design drawing, before assembling the gantry segment, the coordinate data of the actual position of the anchoring point on the roof is measured on site, and then the height of each longitudinal keel is adjusted according to the deviation between the measured coordinate data and the design value, so that the anchoring point at the lower part of the longitudinal keel is matched with the position of the anchoring point on the roof.
Further, the traction device used in step (S5) is preferably a hoist.
Further, the sliding rail is fixed on the roof by a group of supporting components, one supporting component is arranged along each interval of the sliding rail at one end, and the height of each supporting component can be independently adjusted so as to freely adjust the height of each part of the sliding rail. In addition, the slide rail generally adopts a hollow steel pipe with a rectangular section, has certain toughness and deformability, and can meet the requirement of height adjustment.
Further, the supporting component comprises a hoop buckle, a threaded rod and a bearing seat; the top of the bearing seat is provided with an inverted U-shaped opening for accommodating the sliding rail; the lower part of the bearing seat side is provided with a vertical through hole part for the threaded rod to pass through, and a group of nuts are sleeved on the threaded rod to fix the bearing seat on the threaded rod; the bottom of the threaded rod is fixed with a hoop buckle which can be connected with a steel structure of a roof.
Further, the nut includes a pair of support nuts and a press nut; the support nut is located the below of vertical through-hole portion, and the pressfitting nut is located the top of vertical through-hole portion.
Further, self-tapping screws are drilled inwards on the side walls of the inverted U-shaped opening so as to fix the sliding rail in the U-shaped opening.
Further, after the step (S5) is completed, the heights of all parts on the sliding rail are adjusted by screwing the supporting nuts and the pressing nuts, so that the anchoring point at the lower part of the longitudinal keel is accurately aligned with the corresponding anchoring point on the roof, and then the longitudinal keel is fixed. The fixing modes are various, such as welding fixing, riveting fixing, bolting fixing and the like, and can be reasonably selected according to actual conditions.
The beneficial effects are that: compared with the prior art, the construction method of the skylight fixing frame provided by the invention has the following advantages:
(1) As the gantry segments are assembled on the ground, the operation space is large, and the efficient collaborative operation of various large-scale machines is facilitated, the construction speed can be greatly improved.
(2) The gantry segments are assembled on the ground, so that the ground construction difficulty is low, the assembling precision of the gantry segments is convenient to accurately control, the construction quality is ensured, and the difficulty for subsequent roof alignment operation is reduced.
(3) Because the construction modes of ground assembly and integral hoisting are adopted, a large amount of work is transferred from the roof to the bottom surface, so that the damage of construction operation to the roof can be greatly reduced.
(4) Because the sliding rail is erected on the roof, the hoisting equipment only needs to lift the gantry segment to the height of the roof and does not need long-distance translation, so that the shape selection of the hoisting equipment can be reduced, the operation can be performed on a small-area ground construction site, and the construction of a large-scale skylight keel on the large-span roof can be realized at lower cost.
(5) The heights of all parts of the sliding rail can be freely adjusted, so that the gantry segment can be conveniently aligned and installed, and the gantry segment is efficient and accurate.
