Description
Technical field
The utility model relates to the topping instrument of a kind of cast-in-place concrete floor construction, particularly relates to lower protective layer on a kind of plate muscle being applied to slab thickness and the control of plate tendon protective layer thickness and controls split heads.
Background technology
In reinforced bar engineering, by the requirement of specification atlas, slab tendon protective layer has different protective layer thickness in different environments.Traditional form of construction work is that upper lower protective layer separate type controls, and namely at plate lower rebar underlay concrete block, under upper layer plate-rib, places steel bar horse-shaped bench.Palette muscle alternate nodes position cannot ensure all have split heads or cushion block to support up and down, easily cause upper and lower plates tendon protective layer uneven, and up-protective layer is without effective control mode.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of ensure simultaneously plate muscle interlock the upper and lower protective layer thickness in position evenly and on the plate muscle that execute-in-place is convenient, efficiency of construction is high lower protective layer control split heads.
In order to solve the problems of the technologies described above, on the plate muscle that the utility model provides, lower protective layer controls split heads, precast concrete solid is provided with and bears weight and ensure the first concrete column that component stability is erect and the second concrete column simultaneously, the first described concrete column and the upper end of the second concrete column connect with horizontal gird and be formed with neutral gear between the first described concrete columns and the second described concrete column, the first described concrete column and the second described concrete column are equipped with carrying, the bilevel upper strata cantilever of fixed head muscle and lower floor's cantilever, described upper strata cantilever is vertical with the longitudinal surface of described neutral gear with the bearing surface of lower floor's cantilever.
All haunch is provided with on the upside of the downside of described upper strata cantilever and described lower floor's cantilever.
The armpit of described haunch is long, armpit is wide is 10mm.
The sectional dimension of the first described concrete column and the second described concrete column evenly increases from top to bottom, and entirety is similar to trapezoidal basis.
The height of described horizontal gird is thickness of protective layer of floor slab a
s, the height of described lower floor's cantilever is protective layer thickness a
s, the end face distance of the upper surface distance member integrated of described upper strata cantilever is protective layer thickness+twice bar diameter, i.e. a
s+ 2d.
φ 6 " U " shape reinforcing bar is furnished with in the first described concrete column, the second concrete column and horizontal gird.
Adopt lower protective layer on the plate muscle of technique scheme to control split heads, solve job site long-standing cast-in-place concrete floor protective layer thickness and the unmanageable problem of floor thickness of slab, reduce construction cost, improve efficiency of construction and construction quality.
This technological merit is as follows:
(1) because structure manufacture makes in strict accordance with cast-in-place concrete floor thickness and code requirement thickness of protection tier, ensure that its accuracy;
(2) high, the good integrity of component strength, then binding reinforcement colligation, plays good fixed effect to reinforcement installation, avoids conducting oneself with dignity the transposition caused because of reinforcing bar;
(3) member height takes thickness of slab, doublely can do ash cake and use, decrease construction operation amount.
In sum; the utility model is that a kind of cast-in-place concrete floor thickness and plate tendon protective layer thickness deficiency of solving waits common quality defect and lower protective layer control split heads on the plate muscle that adopts; easy to make, structure is simple, dependable performance, with low cost; improve effect, environmental protection, can large-scale popularization use.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
See Fig. 1, Fig. 2, Fig. 3 and Fig. 4, precast concrete solid 1 is provided with and bears weight and ensure the first concrete column 2 and the second concrete column 3 that component stability is erect simultaneously, the upper end of the first concrete column 2 and the second concrete column 3 connects to ensure structural integrity with horizontal gird 8 and be formed with neutral gear 4 between the first concrete column 2 and the second concrete column 3, first concrete column 2 and the second concrete column 3 are equipped with carrying, the bilevel upper strata cantilever 5 of fixed head muscle and lower floor's cantilever 6, upper strata cantilever 5 is vertical with the longitudinal surface of neutral gear 4 with the bearing surface of lower floor cantilever 6.Upper strata cantilever 5 and lower floor's cantilever 6 are responsible for load to be passed to the first concrete column 2 and the second concrete column 3.All be provided with haunch 7 on the upside of the downside of upper strata cantilever 5 and lower floor's cantilever 6, avoid cantilever and column node weak area to be destroyed.The armpit of haunch 7 is long, armpit is wide is 10mm.The sectional dimension of the first concrete column 2 and the second concrete column 3 evenly increases from top to bottom, and entirety is similar to trapezoidal basis.
The height of horizontal gird 8 is thickness of protective layer of floor slab a
s, the height of lower floor's cantilever 6 is protective layer thickness a
s, the end face distance of the upper surface distance member integrated of upper strata cantilever 5 is protective layer thickness+twice bar diameter, i.e. a
s+ 2d.
φ 6 " U " shape reinforcing bar is furnished with, in order to increase component strength in the first described concrete column 2, second concrete column 3 and horizontal gird 8.This portion top surface absolute altitude is concordant with cast in place concrete plate top, and bottom surface is with at the bottom of floor, and whole height is thickness of slab H.
See Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, lower protective layer on this plate muscle after colligation completes, then is controlled split heads and passes from the plate muscle binding site that interlocks, on upper and lower plates muscle respectively lower cantalever placed on it by plate muscle.When upper board muscle is placed, first the lower floor's reinforcing bar perpendicular to upper strata cantilever 5 is positioned on upper strata cantilever 5, as far as possible near the first concrete column 2 and the second concrete column 3 during placement, avoid landing, then upside reinforcing bar is placed on (perpendicular to lower floor's reinforcing bar) on lower floor's reinforcing bar through the neutral gear 4 the first concrete column 2 and the second concrete column 3, the iron wire colligation of two reinforcing bars, avoids the reinforcing bar changing of the relative positions; Lower rebar laying method is identical.
On this plate muscle, lower protective layer controls split heads simple operation, both for upper floor concreting provides top reference, in turn ensure that lower protective layer uniformity, and greatly improves efficiency of construction.
