As depicted in figs. 1 and 2, a kind of cantilevered structure truss combined support system of the invention, including Cantilever Beams I-steel 1,
Transverse horizontal I-steel 3, end support channel-section steel 5, midfoot support channel-section steel 4, truss member 6 and scaffold support system 2；It is described outstanding
Outrigger I-steel 1 has many, in same level, is separately fixed on floor and stretches out outside floor；The Cantilever Beams work
The top of word steel 1 is provided with transverse horizontal I-steel 3, and end support channel-section steel 5 and midfoot support channel-section steel 4 and difference are provided with below
It is welded and fixed in the contact position with two kinds of channel-section steel upper ends, the upper end and the upper end of midfoot support channel-section steel 4 of end support channel-section steel 5 are maintained
Certain spacing；The lower end of the end support channel-section steel 5 and lower floor's floor of the place floor of Cantilever Beams I-steel 1 are fixed；Institute
The lower end and lower floor's floor of the place floor of Cantilever Beams I-steel 1 for stating midfoot support channel-section steel 4 are fixed；The end support channel-section steel 5
Many truss members 6 are welded between midfoot support channel-section steel 4；The scaffold support system 2 is arranged on transverse horizontal
The top of I-steel 3.The present embodiment forms a support platform by the Cantilever Beams I-steel 1 of setting, in Cantilever Beams I-steel 1
Lower section end support channel-section steel 5 and midfoot support channel-section steel 4 are set, form dual support so that the support platform is more consolidated, and is entered
And make it that the scaffold support system 2 that its top is set is also safer and stably, the need for being easy to construction；Cantilever Beams I-steel 1
Top effect the setting up for convenience of scaffold support system 2 of transverse horizontal I-steel 3 is set；End support channel-section steel 5 is with
Welded truss rod member 6 is primarily to reinforcement effect between portion's support channel-section steel 4 so that the steadiness of whole support system is more preferable,
Bearing capacity is bigger, while also safer, the welding position of truss member 6 and quantity can be tested according to engineering design plan (EDP) calculated description
Calculate result and actual size is adjusted.
Cantilever Beams I-steel 1 described in the present embodiment is further set coordinates 10mm thick by the U-shaped ring 7 being embedded in floor
Steel pressing plate be fixed on by double nut on floor.It is more convenient that Cantilever Beams I-steel 1 is fixed in this way, while
More preferably dismounting, and fixed effect is also very good.
The present embodiment further sets the U-shaped ring 7 of the fixed every Cantilever Beams I-steel 1 to be 3, be separately positioned on away from
From at the end 200mm of Cantilever Beams I-steel 1, at the 400mm and non-cantilevered structure edge of floor edge.Fixed every Cantilever Beams are set
The U-shaped ring 7 of I-steel 1 is 3, that is, sets three fixed positions, and these three positions are respectively the end position of Cantilever Beams I-steel 1
Install 2, the non-cantilevered structure marginal position of floor edge sets 1, equivalent to the medium position of Cantilever Beams I-steel 1, so
Set-up mode cause fixed effect more prominent, it is safer, it is to avoid the generation of accident.If Cantilever Beams I-steel 1 is long
Words, can also set a U-shaped ring 7 to be fixed again by the medium position of Cantilever Beams I-steel 1 on floor, stable to increase it
Property.
It is 18# I-steel that Cantilever Beams I-steel 1 described in the present embodiment and transverse horizontal I-steel 3, which are further set,.
It is 10# channel-section steels that end support channel-section steel 5 described in the present embodiment and midfoot support channel-section steel 4, which are further set,.
The present embodiment further sets the scaffold support system 2 to use fastener type steel pipe scaffold, and specification is Φ 48
× 3.5 steel pipes, i.e., a diameter of 48mm, wall thickness is 3.5mm steel pipe.
The present embodiment further sets Cantilever Beams I-steel 1, transverse horizontal I-steel 3, end support channel-section steel 5, middle part branch
The specification of steel pipe in channel-section steel 4 and scaffold support system 2 is supportted, is advantageous in that the construction material of these specifications is common, easily buying, easily
Processing, while performance is also very superior；Scaffold support system 2 uses fastener type steel pipe scaffold, and the steel pipe scaffold is convenient
Build, convenient dismounting, the need for being well positioned to meet construction.
The upper end of end support channel-section steel described in the present embodiment 5 and midfoot support channel-section steel 4 is cut into and Cantilever Beams I-shaped
The parallel inclined-plane of the contact surface of steel 1 and two-sided full weld are connected to the lower section of Cantilever Beams I-steel 1.This connected mode is set, can be with
Make connection effect more preferably, the steadiness of whole support system is also more preferable.
The lower end of end support channel-section steel described in the present embodiment 5 and midfoot support channel-section steel 4 is cut into and floor contact surface
Parallel inclined-plane and two-sided full weld is fixed on steel pressing plate, the steel pressing plate is fixed on floor by chemical bolt.This reality
The connected mode that example sets this channel-section steel and floor is applied, is conveniently built, convenient dismounting, good fixing effect.
The end support channel-section steel 5 and midfoot support channel-section steel 4 of the lower section of Cantilever Beams I-steel 1 of the present embodiment every are mutually flat
OK.Set end support channel-section steel 5 and midfoot support channel-section steel 4 to be parallel to each other, the support of the lower section of Cantilever Beams I-steel 1 can be caused more
It is firm, stress is more balanced so that whole support system is also more stable and safe.
Fixed described in the present embodiment between transverse horizontal I-steel 3 and Cantilever Beams I-steel 1 by spot welding.Transverse horizontal work
Word steel 3 can without using elongated I-steel, but from security consideration, its length requirement no less than 3 across.
The installation and dismounting of a kind of cantilevered structure truss combined support system of the present invention are convenient to, its install and
Demounting procedure difference is as follows：
Installation steps：
(1) line setting, determines each position various types of materials size；
(2) Cantilever Beams I-steel 1 is hoisted in floor and installed；
(3) end support channel-section steel 5, midfoot support channel-section steel 4, truss member 6 are transported to professional processing site, using factory's machine
Toolization makes bottom composite roof truss, it is ensured that welding quality meets intensity requirement；
(4) bottom composite roof truss is hoisted into operating location using crane hoisting equipment to be welded and fixed；
(5) transverse horizontal I-steel 3 is hoisted on Cantilever Beams I-steel, scene is fixed using spot welding mode；
(6) scaffold support system 2 is set up, upper mould, casting concrete etc. are installed.
Start to remove after superstructure concrete strength reaches 100%, demounting procedure is specific as follows：
(1) scaffold support system 2 is removed；
(2) hung over using steel wire rope by composite roof truss fixation, then by steel wire rope on the suspension hook of crane hoisting equipment, first
The fixing point of dismountable truss and Cantilever Beams I-steel 1, rear to remove composite roof truss and floor fixing point, dismounting is used after finishing
Crane hoisting equipment hangs composite roof truss to ground；
(3) transverse horizontal I-steel 3 is removed；
(4) Cantilever Beams I-steel 1 is removed.
Because there is work high above the ground in work progress in cantilevered structure truss combined support system involved in the present invention
Risk, reliable safety prevention measure should be taken with ensure to pacify tear open and construction operation safety, such as at transverse horizontal I-steel 3
Horizontal safety plain net is set, horizontal safety is set up using steel pipe scaffold in the cantilevered structure truss combined support system bottom and chooses
Net etc..
