Description

Swimming hall raising-plate high-supported formwork job practices

Technical field

The present invention relates to a kind of swimming hall raising-plate high-supported formwork job practices.

Background technology

Existing swimming hall raising-plate high-supported formwork difficulty of construction is large, construction is complicated, requires further improvement.

Summary of the invention

The object of the present invention is to provide a kind of easy construction, the swimming hall raising-plate high-supported formwork job practices that construction effect is good.

Technical solution of the present invention is:

A kind of swimming hall raising-plate high-supported formwork job practices is characterized in that: comprise the following steps:

(1) slab form construction

(1) set up form

Roof plate template adopts the thick bamboo plywood of 12mm, adopts 50mm * 80mm flitch to do inferior stupefied, middle apart from 300mm, adopt Φ 48 * 3.0mm steel pipe to decide stupefied, spacing 1200mm adopts the full steel pipe scaffold of ф 48 * 3.0 to do support system, vertical rod spacing in length and breadth is 1200mm, step pitch h=1.2m; The level liftoff 200mm of bar that sweeps the floor, crossbar is stretched out and is effluxed vertical rod 0.1m; At the 4.5m place, wall-connecting piece is set and is connected with agent structure, wall-connecting piece spacing 6.0m, the opposite face 0.9m that staggers arranges; The inside and outside facade of support surrounding is completely established bridging, and establish together every 4～6m at the middle part; Frame bottom, top arrange one level and add layer; The piece of template die is with on tape sticker, and the piece of template die and beam form all arranges sponge strip, with mortar leakage prevention;

(2) set up order

Set up and frontly first swimming pool bottom is cleaned out, when setting up, the shelf bottom of upright rod adds base, erect successively end vertical rod to both sides from the bight, after the bottom is fixing with the bar snapping of vertically sweeping the floor, install the bar of laterally sweeping the floor, and fix with vertical rod, after 3～4 vertical rods are holded up on every limit, install immediately first step vertical equity bar and transverse horizontal bar; Proofread and correct the vertical and horizon bar level of vertical rod, tighten fastening bolt by 45～55Nm moment, form the initial segment of framed bent, extend forward successively by above-mentioned requirements and set up, complete until first step frame is handed over to enclose; Second step, the 3rd step are set up in operation procedure and requirement by first step frame; Along with setting up process installing wall-connecting piece and shearing support, add plain net;

The shuttering supporting steel pipe is at the flooring snap the line, underlay 50mm * 100mm flitch; The steel pipe framed bent is set up smooth vertical and horizontal, is communicated with in length and breadth, and levels support top position consistency, horizontal stay bolt is communicated with; Template first row time stupefied flitch is near wallboard, and if any gap weather strip sealing of hole, between template and template, splicing seams less than 1mm, otherwise seals with adhesive tape; Top board grid in length and breadth digs into same specification with thicknesser, and draws logical line levelling; The grid of surrounding, snap the line remain on same absolute altitude, and plate and grid are fixing with 50mm spike, and Grill space 300mm after plate has spread, proofreaies and correct absolute altitude with level gauge, and uses the guiding ruler levelling; During laying surrounding template, flush with wall, add weather strip, when the template die turnover is used, the cement mortar on surface is cleaned out, the brushing release agent is in time repaired and changes to guarantee that seam is tight the template of distortion and surrounding breakage, and the plate face is smooth; After template has spread, foreign material are cleaned out, brushed release agent;

(2) beam forms construction

Set up vertical rod longitudinal pitch 600mm, vertical rod horizontal spacing 300mm, vertical rod step pitch 600mm with the full hall of floor bracing frame; Sweep the floor bar apart from ground 200mm; Frame bottom, top, centre arrange one horizontal bracing diagonal as horizontal enhancement Layer every 4m;

At the bottom of beam, side form adopts the thick veneer of 18mm, the back side adopts the elongated vertical wood of 50mm * 100mm stupefied, wooden stupefied spacing: bed die is that 200mm, side form are 300mm; Formwork edge joint is less than 1.5mm, and vertical rod is 600mm along beam span direction spacing, and at the bottom of beam, the load-bearing vertical rod is 3, and little cross bar spacing is 300mm, and the scaffold step pitch is 600mm, 8.4 meters of scaffold building height; The steel pipe main joist is adopted at steel pipe framed bent top, wooden a tree, used in making timber for boats joist, and upper berth overlay film composite board forms large beam bottom board; The split bolt steel pipe clamp is not more than 550mm along the spacing of beam length direction, and vertical spacing is 300mm, and split bolt is selected φ 14 reinforcement fabrications, and bolt adopts totally four roads up and down.Clamp: adopt φ 48 * 3.0 steel pipes;

During the beam bottom mother plate construction, absolute altitude by design elevation adjustment support, then the levelling of mounting rail soffit formwork, and bracing wire, when beam base plate span greater than and when equaling 4m, span centre beam bottom is by the designing requirement arch camber, as when designing no requirement (NR), springing height is 3/1000ths of beam span, during the primary-secondary beam handing-over, first girder arch camber, rear arch camber secondary beam;

When setting up, the vertical rod advance of beam lower bolster support is arranged along the beam axis direction; The vertical rod transfer is arranged to bilateral symmetry centered by center line at the bottom of beam, and the outermost vertical rod is not more than 150mm apart from beam side distance; Be located at the adjustable base at falsework bottom of upright rod or top, its screw mandrel external diameter is not less than 36mm, and extension elongation is no more than 200mm; When falsework is set up under beam laterally horizon bar stretch in the falsework of beam biside plate and be no less than two vertical rods, and with the vertical rod snapping; The swimming hall falsework carries out anchoring with rigid connecting tube in horizontal enhancement Layer position and frame column; Go up most one cross bar and be not more than 400mm from top template distance; The vertical rod spreading adopts docking, and every bottom of upright rod all arranges chock or scaffold floor; Falsework four limits with middle every 4～6 row's vertical rods should arrange together with vertical bridging, arranged continuously by the end to top; The falsework two ends begin every 2～4 steps, horizontal cross brace to be set downwards from top layer every 4～6 row's vertical rods with middle; The falsework top is connected horizontal enhancement Layer with the bottom: horizontal cross brace is connected with "the" shape with horizontal brace, horizontal brace width is not less than 3m; Setting up steel pipe framed bent in process presses closer tightly with concrete column, the table of having built; Under beam under main joist steel pipe and plate framed bent be linked to be integral body;

The method of taking under prestressed frame beam to increase vertical rod is reinforced, and vertical pole ' s span is 600mm, and ater-casting place's vertical rod supports to the base plate on basis, guarantees that high carriage load energy safe transfer is to sole plate.

Easy construction of the present invention, reasonable, construction speed is fast, and construction quality is good, safety.

The invention will be further described below in conjunction with embodiment.
