Description
Technical Field
The utility model relates to a factory shed construction technical field, concretely relates to bridge construction in-process for process the ceiling supporting beam of large-span factory shed of large-scale component.
Background
In the process of bridge construction, some large-scale components need to be manufactured in temporarily built plant sheds. The factory shed has large construction geometric dimension and high requirement on the stability of a supporting structure of the ceiling. The existing ceiling supporting structure adopts a triangular support, and comprises two inclined supporting beams, the lower ends of the two inclined supporting beams are connected with a cross beam, and the main defects of the structure are as follows:
(1) the height of the cross beam is low, and the height of the whole plant shed needs to be increased to ensure the effective space in the plant shed, so that the construction materials of the plant shed are increased, and the cost is increased;
(2) the length of the beam is consistent with the span of the plant shed, when the span of the plant shed is large, the consumption of materials of the beam is correspondingly increased, and the stability is poor;
(3) because the supporting structure is welded on site, the increase of materials requires more processing time, resulting in long construction period of the plant shed.
Disclosure of Invention
The utility model aims to provide a large-span factory shed ceiling supporting beam that simple structure, process velocity are fast, material consumption is low to the above-mentioned not enough that current factory shed ceiling bearing structure exists.
The technical scheme of the utility model as follows:
the utility model provides a large-span factory shed ceiling supporting beam, includes two raking supporting beam, its characterized in that: each inclined supporting beam is of a space truss structure with a square cross section and comprises two upper chords and two lower chords, the upper chords and the lower chords are all through-length angle steels, and a plurality of web members are welded between the two upper chords, between the two lower chords and between the opposite upper chords and the opposite lower chords respectively; one ends of the two inclined supporting beams are welded with each other, and an included angle of more than 150 degrees is formed between the two inclined supporting beams; a reinforcing beam is welded between the middle parts of the two diagonal bracing beams, the reinforcing beam comprises two longitudinal rods horizontally arranged, a plurality of transverse connecting rods are welded between the two longitudinal rods, the two ends of each longitudinal rod are respectively welded with the lower chords of the two diagonal bracing beams, and a plurality of vertical connecting rods are further respectively welded between each longitudinal rod and the lower chords of the two diagonal bracing beams.
The utility model discloses compare with a conventional triangle-shaped supporting beam, cancelled traditional crossbeam, because used material is less, the welding cost is low, can save 10% ~ 20% expense on engineering cost, and simple process, production efficiency is high, the on-the-spot processing of being convenient for, reduces 20% relatively in the aspect of the time limit for a project, and the structure is more stable moreover.

FIG. 2 is a cross-sectional schematic view of the raker beam;
fig. 3 is a schematic plan view of the reinforcing beam.
Detailed Description
As shown in fig. 1, the utility model comprises two inclined supporting beams 1 and a reinforcing beam 2; each bracing beam 1 is a space truss structure with a square cross section, and as shown in fig. 2, comprises two upper chords 11 and two lower chords 12, wherein the upper chords and the lower chords are all through-length angle steels, and a plurality of web members 13 are respectively welded between the two upper chords, between the two lower chords and between the opposite upper chords and the opposite lower chords; one ends of the two inclined supporting beams 1 are welded with each other, and an included angle of more than 150 degrees is formed between the two inclined supporting beams; the reinforcing beam 2 is welded between the middle parts of the two diagonal bracing beams, the structure of the reinforcing beam 2 is shown in fig. 3, the reinforcing beam comprises two horizontal longitudinal rods 21, and a plurality of transverse connecting rods 22 are welded between the two longitudinal rods; two ends of each longitudinal rod 21 of the reinforcing beam 2 are respectively welded with the lower chords 12 of the two diagonal bracing beams 1, and a plurality of vertical connecting rods 3 are respectively welded between each longitudinal rod 21 and the lower chords 12 of the two diagonal bracing beams.
In a concrete embodiment of the utility model, a certain steel pipe concrete arch bridge that applicant's construction divides 14 arch rib segments altogether, and the intercostal horizontal tie beam purlin piece is 22 pieces altogether, and the main arch rib crouches to piece and adopts "1 + 1" to piece together the technology in advance, and the main arch rib piece is pieced together in advance, all need welding process in the factory shed in the installation of arch rib web member intersecting line welding and joint connection spare, therefore the factory shed construction requires the span great, and has certain requirement to the inner space height, and a ceiling supporting beam adopts the utility model discloses a structure. In specific implementation, two upper chords and two lower chords of each inclined supporting beam adopt L50 multiplied by 5mm through-length angle steel, web members comprise straight web members and inclined web members, the straight web members and the inclined web members adopt L40 multiplied by 5mm angle steel, and a rectangular frame with 13.6m cross section of 400 multiplied by 400mm is welded; one end of each inclined supporting beam is welded and forms an obtuse angle of 150 degrees. The reinforcing beam is welded between the middle parts of the two diagonal bracing beams, the two longitudinal rods of the reinforcing beam also adopt L50 multiplied by 5mm through-length angle steel, and the cross rods between the two longitudinal rods and the vertical connecting rods between the longitudinal rods and the diagonal bracing beams all adopt L40 multiplied by 5mm angle steel. All the joints of the angle steel rod pieces are welded by full welding.
After the welding of the ceiling supporting beam is completed, the installation is carried out through hoisting equipment, the lower ends of the two inclined support rods and the upright columns on two sides of the shed frame are in butt welding one by one, the erection of the plant shed framework is completed, then the cover plate is installed on the ceiling supporting beam, and the erection of the shed frame is completed.
