Abstract

The invention provides a method for constructing a hollow overlapped rib plate support system, and is characterized in that the method comprises the following steps: 1) locating and paying off; 2) spanning upright rods and level rods, wherein the upright rods of the template support system are exactly supported on the center lines at the bottoms of the frame beam and the rib beam, and the level rods of the support system are spanned; 3) spanning shear supports, wherein vertical continuous shear supports are spanned the upright rods in the middle of each frame mesh and on two sides of the frame beam; 4) mounting templates, wherein the rib beam templates are mounted at the bottoms of the rib beams by the template strips that are 400mm wider than the rib beams, and two sides are 200mm wider than the rib beams; 5) mounting locating stirrups, wherein the locating stirrups and the stirrups of the rib beam, the frame beam and the wall are integrally welded, and each side of each hollow plate is provided with two locating stirrups. The method has good stress performance and large construction operation space, thereby shortening the construction period, reducing the project construction cost, ensuring the integral rigidity and water-proof horizontal side moving rigidity of the hollow plate support system and preventing collapse; and the method is safe and reliable.

Description

Method for constructing hollow overlapped rib plate support system
Technical field
The present invention provides a kind of method for constructing hollow overlapped rib plate support system, belongs to technical field of buildings.
Technical background
At present; The little vertical pole ' s span of the general employing of tradition construction of GBF, BDF hollow overlapped rib plate floor support system, vertical rod transfer, advance generally between 500~650mm, are not considered the mechanical characteristic of hollow superimposed sheet; Vertical rod at the bottom of hollowcore slab causes the hollowcore slab cracking because of transmitting concentrated stress; And in work progress,, bridging can't be set up because the spacing of vertical rod is very close, because of the support system integral rigidity relatively poor; Cave-in accident takes place often, also causes material and artificial significant wastage simultaneously; Close girt strip template die plate adopts the mode of completely spreading template; Not only cause the waste of template, and concrete can cause the hollowcore slab come-up easily from girt strip, the infiltration of Vierendeel girder two side direction hollowcore slabs in the concreting process; Form more than screed at the bottom of making hollow superimposed sheet plate; This layer adhesion strength is poor, very easily comes off, and causes personnel's personal injury in the form removal process easily.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can overcome above-mentioned defective, safe and reliable method for constructing hollow overlapped rib plate support system.Its technical scheme is for taking following steps:
1) location unwrapping wire: on sole plate or cast-in-place plate, emit the close girt strip in top, Vierendeel girder center line according to drawing;
2) set up vertical rod and horizon bar: the vertical rod of form bracing system accurately is supported at the bottom of Vierendeel girder, the close girt strip beam on the center line, sets up the support system horizon bar by step pitch≤1500mm then, so that realize best stress;
3) set up bridging: set up vertical bridging continuously, the angle that bridging and ground formation are 45 °~60 ° in middle part and the vertical rod of Vierendeel girder both sides in length and breadth at each frame column net;
4) lay template: close girt strip template adopts the template bar than the wide 400mm of close girt strip, is placed on the bottom of close girt strip, and each widely goes out close girt strip 200mm both sides, and hollowcore slab is directly done the template of superimposed sheet;
5) lay the location stirrup: adopt the location stirrup of ф 12~ф 20, with the stirrup spot welding of close girt strip, Vierendeel girder, wall be whole, two location stirrups are established in every side of every hollowcore slab, are used for hollowcore slab and locate and antiskid.
The present invention compared with prior art, its advantage is:
1, vertical rod accurately is supported at the bottom of Vierendeel girder, the close girt strip beam on the center line, realizes best stress;
2, the hollowcore slab planar dimension is generally 900 * 900mm at present; Close girt strip breadth of section is generally 200mm; So vertical pole ' s span will reach 1100mm, be that 500mm~650mm support system job practices is saved material about 50% than vertical pole ' s span commonly used, construction operation space is big; Shorten construction period more than 1/3, reduce the work items construction cost more than 26%;
3, all establish vertical bridging continuously in the vertical rod of both sides at the bottom of middle part and the beam in length and breadth at each frame column net, fully guaranteed the integral rigidity and anti-horizontal endurance and stiffness of hollowcore slab support system, prevent to collapse;
4, close girt strip template adopts the template bar than deck-siding 400mm; Not only saved template; Increase the frictional resistance of template and hollowcore slab, prevent the hollowcore slab slippage, and prevent that in the concreting process concrete is from close girt strip, the infiltration of Vierendeel girder two side direction hollowcore slabs; Cause the hollowcore slab come-up, form more than screed;
5, the location stirrup can be used for the location and the antiskid of hollowcore slab.
Description of drawings
Fig. 1 is an embodiment of the invention support system sketch map.
Among the figure: 1, close girt strip template 2, Vierendeel girder 3, close girt strip 4, hollowcore slab 5, location stirrup 6, superimposed cast-in-place plate 7, bridging 8, bottom beam slab 9, stirrup 10, horizon bar 11, vertical rod 12, steel bar stress
The specific embodiment
In the described embodiment of Fig. 1, the step of employing is:
1) location unwrapping wire: on bottom beam slab 8, emit the close girt strip in top 3, Vierendeel girder 2 center lines according to drawing;
2) set up vertical rod and horizon bar: the vertical rod 11 of form bracing system accurately is supported at the bottom of Vierendeel girder 2, close girt strip 3 beams on the center line, sets up support system horizon bar 10 by the 1500mm step pitch then;
3) set up bridging: set up vertical bridging 7 continuously in middle part and the vertical rod 11 of Vierendeel girder 2 both sides in length and breadth at each frame column net, the angle of bridging 7 and 45 °~60 ° of ground formation;
4) lay template: the template bar that close girt strip template 1 adopts than close girt strip 3 wide 400mm, be placed on the bottom of close girt strip 3, each widely goes out close girt strip 3200mm both sides, and hollowcore slab 4 is directly done the template of superimposed cast-in-place plate 6;
5) lay the location stirrup: adopt the location stirrup 5 of ф 12~ф 20, with stirrup 9 spot welding of close girt strip 3, Vierendeel girder 2, wall be whole, every side of every hollowcore slab 4 is established two and is located stirrups 5, is used for hollowcore slab 4 location and antiskid.
Annotate: the bottom beam slab in the step 1) also can be a sole plate.
