The construction method for laying the upper plate ribs of the composite slab according to the present embodiment will be described in detail with reference to fig. 3 to 14.
The construction method for laying the upper plate ribs of the laminated slab mainly comprises the following steps:
the method comprises the following steps: binding at least two longitudinal positioning ribs 12 on the lower side of the truss steel bar 11 at the top of the laminated slab 10, as shown in fig. 3-5;
in this step, preferably, one positioning rib 12 is bound to the lower sides of the truss reinforcements 11 at the two horizontal sides of the laminated slab, in this embodiment, two longitudinal positioning ribs 12 are bound, and the two longitudinal positioning ribs 12 are respectively arranged on the lower sides of the truss reinforcements 11 at the two outermost horizontal sides of the laminated slab. The two longitudinal positioning ribs 12 are arranged along the longitudinal direction of the laminated slab.
Each truss reinforcement 11 includes a bottom rib 111 and a top rib 112 disposed along the horizontal direction of the laminated slab, and an oblique rib 113 connected between the top rib 112 and the bottom rib 111. The longitudinal positioning rib 12 is arranged along the longitudinal direction of the laminated slab and is bound on the lower side of the top rib 112 of the plurality of truss reinforcing steel bars 11. Further, the longitudinal positioning rib 12 may be bound to the lower side of the top rib 112 using a wire rope.
Step two: paving horizontal plate gluten 13 on the laminated slab 10 on at least two longitudinal positioning ribs 12 after binding, as shown in figures 6-8;
wherein, the laying of the horizontal gluten sheets 13 can be carried out by adopting the prior art.
Step S3: paving and binding longitudinal plate gluten 14 on the laminated slab 10 on the paved horizontal plate gluten 13 and the truss steel bar 11, as shown in figures 9-11;
wherein, the laying of the longitudinal plate gluten 14 can be carried out by the prior art. Preferably, the horizontal plate gluten 13 is laid to be flush with the top of the truss steel bar 11, and the horizontal plate gluten 13 may be made of a steel bar having the same diameter as the top bar 112 of the truss steel bar 11. When the longitudinal plate gluten 14 is laid, the top rib 112 of the truss reinforcing steel bar 11 can serve as part of the horizontal plate gluten 13, so that the effect of reducing the dosage of the horizontal plate gluten 13 can be achieved on the basis of meeting the requirement of the strength of the laminated plate gluten. Moreover, the top height of the horizontal plate gluten 13 is consistent with the top height of the truss steel bar 11, so that the thickness of the protective layer on the upper plate surface of the laminated plate can be conveniently controlled.
Step S4: and removing at least two longitudinal positioning ribs 12 as shown in figures 12-14.
After the longitudinal plate gluten 14 is laid and finished and bound with the horizontal plate gluten, two longitudinal positioning tendons 12 on the horizontal two sides of the laminated slab can be removed, the construction of laying the plate gluten on the laminated slab is finished, and the whole construction process is simple to operate.
Compared with the traditional method of sequentially laying longitudinal plate gluten and horizontal plate gluten on the truss steel bars, the construction method for laying the plate gluten on the laminated slab can fully utilize the truss steel bars as part of the horizontal plate gluten, has the effect of saving the steel bars, and is beneficial to controlling the thickness of a concrete protective layer on the laminated slab because the height of the top of the horizontal plate gluten is consistent with that of the top of the truss steel bars.
The effective control of the thickness of the concrete protective layer on the laminated slab by the optimized construction method of the invention is further described with reference to fig. 15 to 18.
Taking the construction site as a class II a environment as an example, the minimum concrete protective layer thickness of the laminated slab is required to be 20mm, and the specification requires that the allowable deviation of the exposed height of the steel bar truss 30 is +5 to-2 mm.
Assuming that the diameters of the horizontal plate gluten 13 and the longitudinal plate gluten 14 are both 8mm, the thickness of the laminated slab 10 is 60mm, the exposed height of the steel bar truss 30 is 45mm, and the height of the cast-in-place concrete on the laminated slab is 80 mm.
If there is no deviation in the exposed height of the steel bar truss 30, the thickness of the concrete protective layer 31 is as follows:
after optimization, the thickness of the concrete protective layer 31 is 27mm (80-45-8) > 20mm, as shown in FIG. 15;
before optimization, the thickness of the concrete protective layer 31 is 19mm (80-45-16) <20mm, as shown in fig. 16;
if the exposed height of the steel bar truss 30 has a deviation of +5mm, the thickness of the concrete protective layer is as follows:
after optimization, the thickness of the concrete protective layer 31 is 22mm (80-50-8) > 20mm, as shown in FIG. 17;
before optimization, the thickness of the concrete protective layer 31 is 14mm (80-50-16) <20mm, as shown in FIG. 18;
obviously, the optimized binding mode is more favorable for controlling the thickness of the concrete protective layer.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; the modifications or substitutions do not cause the essence of the corresponding technical solutions to depart from the scope of the technical solutions of the embodiments of the present invention, and are all included in the scope of the present invention.
