The specific embodiment
Below in conjunction with specific embodiment the present invention is described further.
See also Fig. 1, Fig. 4, hanging truss mould plate job practices under the hollow concrete building plate of a kind of long-span steel pipe of the present invention comprises the steps:
At first carry out preparation of construction;
Then measure unwrapping wire;
Then, steel column 4 and girder steel 5 are installed; The welding of girder steel 5, steel column 4 is welded in strict accordance with the requirement of Construction of Steel Structure inspection of quality standard, PQR, construction steel structure solder technology rules; After weld seam detection is qualified; Foreign material such as the iron rust on the timely removing steel component surface, rubbish are for the next procedure construction is got ready.
The one T type carriage 11 is installed again in first hollow steel pipe 1 time;
See also Fig. 2,3; The one T type carriage 11 is along the axial installation of first hollow steel pipe 1; First end of the one T type carriage 11 is positioned at the first end bottom of first hollow steel pipe 1; Second end of the one T type carriage 11 is positioned at second end, the one constant spacing place of distance first hollow steel pipe 1, and the length of constant spacing is the length of a truss mould plate 21.
Then, a plurality of first hollow steel pipes 1 are installed, are further comprised:
Judge whether each first hollow steel pipe 1 satisfies length requirement, if do not satisfy, the mode of docking through pipeline section makes first hollow steel pipe 1 satisfy length requirement;
First hollow steel pipe 1 that will satisfy length requirement through tower crane is in place;
First hollow steel pipe 1 is welded in respectively between the girder steel 5.
When first hollow steel pipe, 1 length of produce in factory can not meet the demands, can dock at the construction field (site), in docking operation, to prevent deformation of members, strict simultaneously control butt joint welding quality.After 1 butt joint of first hollow steel pipe finishes, need welding quality is carried out ultrasound examination.
Then, truss mould plate 21 is installed, truss mould plate 21 steps is installed further comprises:
First end of current truss mould plate 21 is held on the supporting plate of two an adjacent T type carriage 11 second ends and pushes to the end vertically;
Current truss mould plate 21 and adjacent girder steel 5 are fastenedly connected or are fastened and connected with second end of a last truss mould plate 21;
Repeating step is paved with a T type carriage 11 until truss mould plate 21.
Following hanging truss mould plate plane sequence of construction: the laying of every layer of truss mould plate 21 should be laid to a direction from original position, handles the edge template at last.
See also Fig. 4, the headspace level that truss mould plate 21 never welds a T type supporting plate 11 pushes between two first hollow steel pipes 1, and first truss mould plate 21 pushes away forward along the direction of first hollow steel pipe 1, till near the other end.All truss mould plates 21 all according to said method are installed in the working face.
In order to guarantee the smooth installation of last piece truss mould plate, the bottom T type supporting plate of first hollow steel pipe 1 does not weld earlier, and all headspaces should be near same axis.
Large tracts of land truss mould plate 21 gets into working face and installs and fixes later on, and position, end truss mould plate 22 temporarily is not installed this moment.
Adopt manner to connect between the truss mould plate 21, plate is connected with pull hook between the plate should be tight, spillage not when guaranteeing concreting; It is consistent to guarantee to arrange the plate direction simultaneously.
Span ending place is width if the truss mould plate of the wide not enough 576mm of plate dispatches from the factory, and can on the plate of cutting back a Pin or two truss structure templates 21 should be arranged with truss mould plate 21 along the cutting of truss mould plate 21 length directions, must not truss mould plate 21 be cut off.
Before truss mould plate construction, utilize the transit truss mould plate installation and control line that on floor hollow steel pipe boatswain chair, draws, the straightness error of guaranteeing truss mould plate is 10mm, and the mismatch of plate requires less than 5mm.
After truss mould plate 21 is in place, should be immediately that the vertical reinforcement of its end and bed die and girder steel 5 spot welding is firm.With galvanized steel plain sheet and girder steel 5 spot welding, manual electric arc welding is adopted in welding along its length, and spacing is 300mm.
Then, position, end truss mould plate 22 is installed, position, end truss mould plate 22 steps is installed further comprises;
See also Fig. 5, an end truss mould plate 22 is suspended between second end of adjacent first hollow steel pipe 1 through linking up with 6;
The supporting plate that under second end of first hollow steel pipe 1, welds one the 2nd T type carriage, 12, the two T type carriages 12 respectively sets off position, end truss mould plate 22;
First end of position, end truss mould plate 22 is connected with second end of adjacent truss mould plate 21, and second end and the adjacent girder steel 5 of position, end truss mould plate 22 is fastenedly connected.
Position, end, every zone truss mould plate 22 is after getting into working face, and two ends need be caught on the two ends of position, end truss mould plate 22 with the hook 6 of interim making.Utilize hook 6, hook 6 adopts Φ 10 reinforcing bar field fabrications, and the welding of the 2nd T type carriage 12 at preformed hole position is carried out in the space that truss mould plate 22 pull-ups of position, end come, and carries out the fixing of position, end truss mould plate 22 after welding finishes.
Then, second hollow steel pipe 3 is installed; Second hollow steel pipe 3 is set in parallel between first hollow steel pipe 1, and is fastenedly connected with adjacent girder steel 5.
Colligation floor bottom layer of the reinforcing steel;
Then, in truss mould plate 21 and position, end truss mould plate 22, build the thick concrete of bed die 200mm;
In the thick concreting process of 200mm, the concrete piling height is forbidden to surpass the slab thickness that twice is built, and should not surpass 300mm.
Colligation floor top reinforcement 7 again;
At last, carry out floorslab concrete and build, floorslab concrete is built and is carried out after concrete that step builds in truss mould plate 21 and position, end truss mould plate 22 reaches intensity 75%.
More than combine accompanying drawing embodiment that the present invention is specified, those skilled in the art can make the many variations example to the present invention according to above-mentioned explanation.Thereby some details among the embodiment should not constitute qualification of the present invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
