Abstract
The invention provides a modular mounting technology for a steel-structure door type frame roof system. Upright columns on the ground are sequentially arranged along the length direction of a house; two rows of the columns are respectively arranged in the front of the house and at the rear of the house; a beam is arranged between each front column and the corresponding rear column; the total number of the beams is N; and a distance between each two adjacent beams in the length direction of the house is a beam distance. The modular mounting technology comprises the step of vertically mounting the columns one by one. Ground construction components do not need to be hoisted by a crane when mounted, the using time of crane hoisting equipment is shortened, and the cost is reduced effectively.
Description
Technical field
The present invention relates to field of steel structure, especially relate to a kind of steel work gate-type frame installation technique.
Background technology
Conventional method: C-type steel, angle brace, tie rod, tie-rod etc., after single Pin beam is first-class, are installed one by one with crane equipment by roofing maintenance system between two Pin beams.Whole process installation personnel all will in work high above the ground, and installation procedure is loaded down with trivial details, and construction risk coefficient is very large, expends time in longer.
As shown in Fig. 1 ~ 4, conventional method:
Step one: first one by one pillar is installed (in figure, each pillar all bears serial numbers);
Step 2: by lifting and pillar connection one by one after assembled for roof girder getting well;
Step 3: C-type steel, tie rod, tie-rod etc. are installed one by one by workman on beam;
Step 4: installation.
Summary of the invention
The object of the present invention is to provide a kind of steel work portal frame Roof system modularization mounting process, improve the safety factor of installing, reduce the workload of work high above the ground.
Technical scheme of the present invention is:
Steel work portal frame Roof system modularization mounting process, ground column is arranged successively along the length direction in house, and respectively there is colonnade the front and back in house, are provided with a Pin beam between every two pillars in front and back; Total Pin number of beam is set to N; On the length direction in house, the spacing between adjacent two Pin beams is called case bay; Installation steps:
Step one: first one by one some pillars are vertically installed;
Step 2: carry out ground installation: on the ground two Pin beams are in place, be then in place one by one by the assembled secondary member between two Pin beams of needs, form assembled two good Pin girder constructions, the total quantity of two Pin girder constructions is set to M;
Step 3: according to total Pin number N of beam, the total quantity M of two Pin girder constructions required for calculating, when N is even number, M=N*0.5; When N is odd number, M=(N-1) * 0.5; The two Pin girder constructions of assembled good M;
Step 4: assembled two good Pin girder construction integral hoistings are installed with corresponding pillar and is connected, one, interval case bay between two adjacent two Pin girder constructions;
Step 5: in the middle of adjacent two two Pin girder constructions, workman installs between beam adjacent in two adjacent Pin girder constructions for secondary member;
Step 6: installation.
Secondary member comprises C-type steel, tie-rod, angle brace, tie rod.
Way of the present invention compares with original way:
1, change original construction sequence of work high above the ground that needs of 60% into ground construction, greatly reduce the danger coefficient of workman in construction works.
2, part work progress carries out on ground, and workman by the restriction of installing space, does not substantially increase installation effectiveness.
3, lifting by crane without the need to using crane in the installation of ground construction component, decreasing the time using crane equipment, effectively reducing cost.
4, adopt surface-mounted mode, reduce the degree-of-difficulty factor that Roof system is installed, common laborer can complete on ground.
5, be conducive to checking construction quality (location, fastened by screw degree etc. of purlin).

Detailed description of the invention
As shown in Fig. 1 ~ 6, way of the present invention: two adjacent Pin beams are assembled good on the ground, and all installed by all components such as C-type steel, tie-rod, angle brace, then integral hoisting, is connected with steel column.
Ground column 1 is arranged successively along the length direction in house, and respectively there is colonnade 1 front and back in house, is provided with a Pin beam 2 between every two pillars 1 in front and back.Total Pin number of beam 2 is set to N.On the length direction in house, the spacing between adjacent two Pin beams 2 is called case bay, and the space between adjacent two Pin beams becomes distance between girders space.
Step one: first one by one some pillars 1 are vertically installed;
Step 2: carry out ground installation, on the ground two Pin beams 2 are in place, then the assembled secondary member such as C-type steel, tie-rod, angle brace, tie rod, bolt between two Pin beams 2 of needs is in place one by one, the total quantity forming assembled two good Pin girder construction 3, two Pin girder constructions 3 is set to M;
Step 3: according to total Pin number N of beam 2, the total quantity M of two Pin girder constructions 3 required for calculating, when N is even number, M=N*0.5; When N is odd number, M=(N-1) * 0.5; The two Pin girder constructions 3 of assembled good M;
Step 4: by assembled two good Pin girder construction 3 integral hoistings and corresponding pillar 1(steel column) install and be connected, one, interval case bay between two adjacent two Pin girder constructions 3;
Step 5: in the middle of adjacent two two Pin girder constructions 3, workman installs between beam 1 adjacent in two adjacent Pin girder constructions 3 for the secondary members such as C-type steel, tie-rod, angle brace, tie rod;
Step 6: installation.
Way of the present invention compares with original way:
1, change original construction sequence of work high above the ground that needs of 60% into ground construction, greatly reduce the danger coefficient of workman in construction works.
2, part work progress carries out on ground, and workman by the restriction of installing space, does not substantially increase installation effectiveness.
3, lifting by crane without the need to using crane in the installation of ground construction component, decreasing the time using crane equipment, effectively reducing cost.
4, adopt surface-mounted mode, reduce the degree-of-difficulty factor that Roof system is installed, common laborer can complete on ground.
5, be conducive to checking construction quality (location, fastened by screw degree etc. of purlin).
