Invention content
The technical problem to be solved by the present invention is to:A kind of rack is provided to apply with steel truss light composite board Combined roof Work engineering method.
In order to solve the above technical problems, the technical solution adopted by the present invention is:
Rack provided by the invention and steel truss light composite board Combined roof construction, include the following steps:
(1) preparation of construction
Initial survey is carried out to net rack foundation structure according to drawing requirement before the installation of 1 rack, measuring record will be with drawing phase Symbol, repetition measurement should be carried out if any not being inconsistent, and approved through design side, can be constructed after common solution.
2 conscientiously audit design drawing, grasp position and the specification of steel truss frame plate, check the number and size of plate.
3 leveling places, dredging road, and the barrier in lifting range is removed, ensure that fabricating yard is smooth, solid, road Road is unobstructed.
4 check rod member for grid, sphere, bolt, bearing and the intensity of roof composite board, complete appearance, product certificate Whether meet the requirements.
Horizontal transport machinery, outfitting tool, tool and the rope of the 5 inspection lifting equipments of liftings, ground and roofing be It is no complete, intact, ensure that its is functional, goes slick.
(2) Elements of Space Grid Truss is installed
1 Elements of Space Grid Truss installation use altitude spread roof-member method, first first across set up scaffold be used as operating platform, install first across Rack, follow-up rack installation are assembled using marginal Method for Installation.
2 altitude spread roof-member methods install rack, should measure at any time and check rack quality, check lower edge size of mesh opening and diagonal line, Inspection is winded up size of mesh opening and diagonal line, checks rack longitudinal length, lateral length, grid rise, checks rack entirety amount of deflection, Chord size above and below stringent control rack, it is ensured that each bolt screws in place.
3 racks during the installation process should the sinking situation of each interim fulcrum check at any time should be timely if any situation is declined Consolidation process.
(3) rest installation is fixed
According to rack and roof boarding design grade, precision rest is installed in bolt sphere.
(4) steel truss roof plate lifts
1 roof boarding can be used the method for construction site tower crane lifting in place and be installed.
2 roof boardings should be lifted using suspension hook, monolithic lifting, and answer 4 points of liftings.
The erection sequence of 3 roof boardings can also select rational installation with since structure one end according to live different situations Sequentially.
(5) steel truss frame plate is welded and fixed with rack rest
After lifting is in place, construction personnel adjusts plate in the middle part of structural unit lattice using auxiliary tools such as crowbars, and ensures adjacent Two boards should be at a plane in seam, do not take billet to be padded in plane, then through roof boarding It is welded with the support of structure, level weld seam requirement is as follows:Fusion length along plate transverse and longitudinal be not less than 60mm full welds, weld bead height 5mm, Every block of plate is no less than three spot weldings with structure.
(6) plate stitch is handled
After roof boarding is according to above-mentioned requirements installation in place, the eliminating impurities in plate stitch are clean, the steel skeleton between plate and plate needs One of connecting node is added every 1.5m, is welded to connect as transition piece using steel plate or shaped steel, fusion length is not less than 100mm, weld bead height are not less than 5mm.And plate stitch is carried out using the thermal insulation mortar that polyphenyl polymer mortar or perlite configure Filleting, plate stitch position upper surface must be levelling.
(7) waterproof and protective layer construction
Carry out roof waterproof after the completion of roof composite board construction and protective layer construction, waterproof layer can be used waterproof coiled material, corner and The thin portions such as negative and positive angle should do extra play, and pea gravel concreten protective layer can be used in protective layer.
The Elements of Space Grid Truss that this engineering method uses is used for large span space, and it is small with stress, light-weight, rigidity is big, anti-seismic performance Good advantage.
This engineering method use steel truss light type composite panel be collection lightweight, load-bearing, durable, heat preservation, heat-insulated, waterproof, fire prevention, every The novel light roof-bearing inorganic plate that the functions such as sound, venting of dust explosion and antidetonation are integrated.The plate had both inherited traditional reinforced concrete The reliability of earth house panel, and the advantages of absorb other light weight boards, realize lightweight and it is multi-functional simultaneously, protrusion is finished The safety of structure and durability.
Roof boarding is light-weight, and is lifted for monolithic when lifting, and the method that the original tower crane lifting in construction site can be used carries out Installation, it is easy for construction.
This engineering method utilizes the characteristics of light-duty composite roof board load-bearing, and paving waterproof roll and microlith is poured on roof boarding The problem of concrete, effective solution roof leakage.
This engineering method is suitable for the buildings such as rail traffic, industrial premises, warehouse logistics, large public building, stadiums Roofing is particularly suitable for long-span roofing, widely used.
Beneficial effects of the present invention:
Economic benefit:
This engineering method, instead of reinforced concrete roof board, greatly reduces the reinforcing bar and concrete of roof boarding using composite roof board Dosage.Meanwhile on roofing can directly construction waterproof layer and protective layer, eliminate levelling and look for the ways such as slope, reduce engineering and make Valence.
Elements of Space Grid Truss and the hardened conjunction of steel truss roof, from heavy and light, span is big, anti-seismic performance is good, increases the headroom in house, can have Effect reduces project cost.
All components that this engineering method uses are that factory makes, in-site installation.Rack and roof boarding short construction period, and apply Roof waterproof and protective layer construction can be directly carried out after the completion of work, and reinforced concrete roof long construction period, this engineering method make With the duration is greatly saved.
Roof boarding heat transfer coefficient is low, can meet building energy conservation heat insulation requirement, eliminate roofing heat-insulating layer, reduces engineering and makes Valence.
Skylight is added in steel truss roof composite plate, increases indoor lighting area, has effectively saved the energy, reduces energy Consumption.
Cost analysis is as follows:
Process names Fee of material(Yuan/㎡) Labour cost(Yuan/㎡) Cost(Yuan/㎡)
Rack and steel truss light composite board Combined roof 820 380 1200
Society and environmental benefit:
This engineering method can reduce steel, concrete amount compared with reinforced concrete roof, and can add skylight, be conducive to energy saving and ring It protects in border.
Building using this engineering method is mostly that high can then increase template branch according to reinforced concrete roof across, large span architecture If danger, this engineering method is safe, and further genralrlization has good social benefit.
