Description
Technical field
The invention belongs to the housing construction technical field, a kind of cast-in-place concrete hollow floor slab thin-wall hollow pipe anti-floating construction method particularly is provided, what build is a kind of instrument of cast-in-situ hollow floor plate thin-wall hollow pipe anti-floating, is applicable to the construction of thin-wall hollow pipe as the public and residential construction engineering of cast-in-place concrete floor inside master's material.
Background technology
Cast-in-place concrete hollow floor slab adopts thin-wall hollow pipe as floor inside packing material, has reduced the floorslab concrete material usage, has reduced the floor deadweight; Concrete can be considered " worker " shaped sections between thin-wall hollow pipe when floor slab structure is stressed, has strengthened the stress performance of floor; This structure floor can be designed to the girderless floor of large span.
The cast-in-place concrete hollow floor slab structure also is not used widely in China at present, does not have corresponding construction technology standard yet.
Cast-in-place concrete hollow floor slab thin-wall hollow pipe anti-floating construction method to the anti-floating of thin-wall hollow pipe, anti-ly move, the difficult points such as layout of tension rib in the plate, formed a cover scientific construction process.
Summary of the invention
The object of the present invention is to provide a kind of cast-in-place concrete hollow floor slab thin-wall hollow pipe anti-floating construction method, solved thin-wall hollow pipe anti-floating in the concrete placement, anti-fixedly difficult point problem such as move.
The method that the present invention adopts is as follows:
(1) according to the spacing of thin-wall hollow pipe in the caliber of used thin-wall hollow pipe in the cast-in-place concrete hollow floor slab and the cast-in-place concrete hollow floor slab, welding thin-wall hollow pipe anti-floating frame, the anti-floating frame is placed on the thin-wall hollow pipe two ends.
(2) the anti-floating frame is by the horizontal steel plate of anti-floating with anti-move stave sheet and constitute, the horizontal steel plate of anti-floating and anti-ly move the steel plate bar that stave sheet adopts 40*2mm, the horizontal steel plate length of anti-floating be 6 thin-wall hollow pipe calibers and 6 thin-walled hollow tube pitch with.Anti-move stave sheet and be vertically welded on the horizontal steel plate of anti-floating, the anti-stave sheet that moves begins welding from the horizontal steel plate of anti-floating end, and anti-spacing of moving stave sheet is followed successively by thin-wall hollow pipe caliber and two thin-walled hollow tube pitch.Anti-move vertical steel plate length and equal the thin-wall hollow pipe caliber; Thin-wall hollow pipe interted successively move between vertical steel plate at the anti-of two anti-floating framves.
(3) 6 thin-wall hollow pipes in parallel thin-wall hollow pipe length direction interval are established one anti-floating and are socketed steel disc, and anti-floating sockets steel disc the anti-floating frame is held together, anti-floating frame skew when preventing concrete pouring;
(4) at interval 10 thin-wall hollow pipe settings socket line the template of anti-floating frame and underfloor are socketed, and the anti-floating frame floats when preventing concrete pouring.
Beneficial effect of the present invention
Cast-in-place concrete hollow floor slab is a kind of New Building Materials that integrate load-bearing, insulation, lightweight, heat insulation, sound insulation, premium properties such as fire-resistant, durable.Cast-in-place concrete hollow floor slab thin-wall hollow pipe anti-floating construction method has solved in the concrete placement thin-wall hollow pipe come-up, sidesway, can not guarantee between thin-wall hollow pipe between spacing and thin-wall hollow pipe and levels reinforcing bar technical barriers such as spacing; For cassette ceiling thin-wall hollow pipe anti-floating, anti-move, fixed-site provides instrument.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing and implementation method.
Fig. 1 is the fixing sectional drawing of cast-in-place concrete hollow floor slab thin-wall hollow pipe.Wherein, thin-wall hollow pipe 1, concrete hollow floor 2, the horizontal steel plate 3 of anti-floating, anti-ly move that stave sheet 4, anti-floating socket steel disc 5, socket line 6, slab form 7, thin-wall hollow pipe diameter 8, thin-walled hollow tube pitch 9.
Fig. 2 is the cast-in-place concrete hollow floor slab sectional drawing.
Fig. 3 is cast-in-place concrete hollow floor slab thin-wall hollow pipe and anti-floating frame connection layout.
Specific implementation method
According to the spacing f of thin-wall hollow pipe 1 in the caliber d of used thin-wall hollow pipe 1 in the cast-in-place concrete hollow floor slab 2 and the cast-in-place concrete hollow floor slab 2, welding thin-wall hollow pipe 1 anti-floating frame.
The anti-floating frame is by the horizontal steel plate of anti-floating 3 and anti-ly move stave sheet 4 and constitute.Horizontal steel plate 3 of anti-floating and the anti-stave sheet 4 that moves adopt the thick narrow steel plate bar of 2-3mm, and horizontal steel plate 3 length of anti-floating are 5-6 root thin-wall hollow pipe 1 caliber d and spacing f sum value.Anti-move stave sheet 4 and be vertically welded on the horizontal steel plate 3 of anti-floating, the anti-stave sheet 4 that moves begins welding from the horizontal steel plate 3 end certain distances of anti-floating, and spacing is thin-wall hollow pipe 1 caliber 8 and two thin-wall hollow pipes, 1 spacing 9 successively.It is anti-that to move vertical steel plate 4 length be thin-wall hollow pipe 1 caliber 8.
Anti-floating frame welding finishes, and is placed on the template 7 of cast-in-place concrete hollow floor slab 2, then thin-wall hollow pipe 1 is interted successively anti-4 of vertical steel plates that move at two anti-floating framves.
Thin-wall hollow pipe 1 is placed on the anti-floating frame and is finished, and 5-6 root thin-wall hollow pipe 1 is elongated at interval establishes one anti-floating and socket steel disc 5 along cast-in-place concrete hollow floor slab 2.Anti-floating sockets steel disc 5 perpendicular to the horizontal steel plate 3 of anti-floating frame anti-floating, and anti-floating sockets steel disc 5 the anti-floating frame is held together, anti-floating frame skew when preventing concrete pouring.
Keeping at a certain distance away to be provided with on the horizontal steel plate 3 of the anti-floating of anti-floating frame sockets line 6, the template 7 under anti-floating frame and the cast-in-place concrete hollow floor slab 2 is socketed anti-floating frame come-up when preventing concrete pouring.
