Drawings
FIG. 1 is a schematic view of a construction plan of a folding floor with edge-belt independent supports.
Detailed Description
With respect to the above technical solutions, preferred embodiments will be described in detail with reference to the drawings.
As shown in fig. 1, in the construction method of the belt-type independent support for overlapped floor boards of the fabricated structural system, a support frame comprises a steel pipe vertical rod 1, a horizontal rod 2, a sweeping rod 3, an adjustable bracket 4, a batten 5 and a template 6. The building comprises a wall 7, a cast-in-place beam 8, a wall template 71, a beam template 81 and a composite slab 9.
Step 1), erecting a support frame: a bottom supporting base plate is placed on the ground, then a plurality of steel pipe vertical rods 1 are arranged at intervals along the length directions of the wall, the cast-in-place beam and the slab band at a position 30cm away from the side surfaces of the wall 7 and the cast-in-place beam 8 and below the central part of the slab band area, and then the steel pipe vertical rods 1 are connected and fixed through a floor sweeping rod 3, a horizontal rod 2 and a fastener. The ground sweeping rod 3 is 20cm away from the ground. An adjustable bracket 4 is connected to each steel pipe upright rod 1 through threads, and battens 5 are arranged on the adjustable brackets 4. After the support frame is erected, laying prefabricated laminated plate edges and templates 6 at the plate strips on the battens 5. The width of the battens 5 below the plate strip is the same as the width of the template or slightly larger than or slightly smaller than the width of the template, and the battens 5 below the plate strip can be built by a plurality of battens to form a batten group with a certain width and a support. During construction, the reinforcing steel bars such as wall beams and the like are firstly bound and supported, and when the support frame is erected, the wall template 71 and the beam template 81 exist. One end of the template 6 positioned at the wall beam is erected on the wall template or the two templates, and the other end is erected on the battens 5 at the side of the wall or the beam. Because the distance between the steel pipe vertical rod at the wall beam side and the wall beam is only 30cm, and the laminated slab extends into the wall column support by 10mm, the corresponding supports bear the upper load together, but the independent support system is mainly used for bearing the upper load, and the template 6 at the wall beam side does not need to be supported by the wall template 71 and the beam template 81.
In the erection process, the height of the steel pipe upright stanchion is adjusted through the adjustable bracket. The step pitch of the support frame is according to the design requirement. After the support frame is erected, team self-checking is needed to be carried out, and the next procedure can be carried out after the self-checking is free of problems.
When the laminated slab has a large span for the laminated slab, an independent support is additionally arranged in the middle of the slab span, so that the laminated slab forms a simple support plate and a continuous plate in the construction stage. The independent support comprises a plurality of independent steel pipe vertical rods, adjustable brackets arranged at the tops of the steel pipe vertical rods and battens, and the independent support and the support frame jointly bear the load of an upper structure.
No matter the support frame or the independent support, when the height is adjusted, the adjustment can be realized by arranging the base plate.
Step 2), after the side-band type independent supporting frame is erected, sewing a positioning line on a template according to a design drawing; the hoisting laminated slab is placed on the support frame, so that the laminated slab is positioned on the template 6. When the distance between the hoisted composite slab and the template is 500mm, the descending speed needs to be slowed down, the composite slab is placed in a designated area according to a slab joint positioning line, one end of the composite slab close to the side of the wall beam extends into the wall beam by 10mm, reserved steel bars of the composite slab are bound with the wall beam, and reserved steel bars of two composite slabs at the plate strip are bound; the upper load, such as construction load, concrete pouring load and the like, is borne by the support frame, the wall beam support, the support force after the steel bars are bound and the bending rigidity of the laminated slab; and (5) after the steel bar binding is finished and the water and electricity alternate operation and the like are completely finished, checking and accepting.
When the laminated slab is hoisted, a special lifting appliance is needed, and the laminated slab is prevented from cracking due to the concentrated stress. When the prefabricated composite beam is hoisted, whether the joint between the slab bottom and the prefabricated composite beam or the shear wall is in place or not is checked in time, and whether the length of the prefabricated floor slab reinforcing steel bar penetrating into the wall meets the requirement or not is checked until the hoisting is finished.
And 3) after the acceptance is qualified, carrying out concrete pouring together with the cast-in-place beam, the wall joint, the slab band and the like. And after the strength of the concrete meets the requirement, dismantling the support frame, the battens and the template.
Compared with a wood keel full-hall supporting scaffold supporting system and a steel pipe full-hall scaffold profile steel main keel supporting system, the supporting construction method has the advantages that the self bending rigidity of the concrete prefabricated laminated slab is utilized, the supporting frames are only arranged at the positions 30cm away from the two sides of the wall beam and at the position of the laminated slab band, the supporting system meets the requirements of stability and deformation control, the safety can be guaranteed in the concrete pouring process, the laminated slab can guarantee that the floor flatness meets the requirements by means of the self bending rigidity, the construction process is simple, the operation is convenient, the resource investment is reduced, the construction period is saved, the construction cost is reduced, and the economic benefit is improved.
