Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further details:
The utility model provides a kind of cast-in-situ concrete beam slab, as shown in Figure 1, comprises main reinforcement 2, stirrup 3, bearing bar 4, cushion block 5, top plate thickness 6 bottom beam upper strata main reinforcement 1, beam.
Wherein, cast-in-situ concrete beam slab is formed primarily of beam steel and concrete, and beam steel comprises main reinforcement 2 and stirrup 3 bottom beam upper strata main reinforcement 1, beam.The structure that beam and top board connect as one, concrete forms concrete cover around beam steel, and cast-in-situ concrete beam slab is the beam of the concrete cover formed around beam steel, and the concrete roof connected as one with beam.Bearing bar 4 is positioned at the below of beam upper strata main reinforcement 1; and support beam upper strata main reinforcement 1; cushion block 5 is positioned at below bearing bar 4, concrete cover 6 upper end, beam side, and in cast-in-situ concrete beam slab, bearing bar 2 two ends respectively pave one piece of cushion block 5, are in equilibrium state to make bearing bar 2.Beam upper strata main reinforcement 1 is positioned at the upper end of beam, and the lower end of beam arranges main reinforcement 2 bottom beam, and main reinforcement 2 bottom beam upper strata main reinforcement 1 and beam is fixed by stirrup 3.It should be noted that, beam upper strata main reinforcement 1 and stirrup 3 upper end are interspersed with roof steel bar, beam upper strata main reinforcement 1 and the upper surface of stirrup 3 and the upper surface flush of roof steel bar.
Wherein, cushion block 5 for length be 50 millimeters, width is the cushion block of 50 millimeters; its thickness, according to acquisition, wherein, represents the thickness of cushion block; represent top plate thickness; top board is positioned on the stirrup of colligation beam, represents top board upper strata thickness of concrete cover, represents the diameter of stirrup; represent the diameter of described beam upper strata main reinforcement, represent the diameter of bearing bar.
The length of bearing bar 4, according to acquisition, wherein, represents the length of bearing bar, represents the width of beam cross section, represent the width of cushion block.In addition, when determining the diameter of bearing bar, the weight of needs according to the beam upper strata main reinforcement that bearing bar is arranged and roof steel bar etc. and the load-bearing of bearing bar.
In the utility model, cushion block 5 bears the weight of bearing bar 4, beam upper strata main reinforcement 1 and part beam etc., thus can reduce the load-bearing of cushion block, extends the application life of cushion block.The schematic diagram of cast-in-situ concrete beam slab that theres is provided of prior art as shown in Figure 2; in prior art, cushion block 5 is placed in the concrete cover bottom beam; the total weight of beam steel and beam need be born; easily cause the problem that cushion block damages by pressure, is shifted; if cushion block pad is bottom beam below main reinforcement 2 in addition; the then colligation silk part unbalance stress of main reinforcement 2 bottom stirrup 3 and beam; easy fracture; if cushion block is positioned over below stirrup 3, the stressed large disconnection of colligation Si Yiyin of main reinforcement 2 bottom the stirrup 3 so near cushion block 5 both sides and beam.
Therefore, the utility model, due under cushion block is positioned at beam upper strata main reinforcement and bearing bar, can solve in prior art because of problem that the placement location of cushion block easily causes.And the utility model is by changing the placement location of cushion block, making concrete cover can protect bottom beam and the reinforcing bar of beam both sides does not expose, the thickness of concrete cover of beam steel can be controlled.
When constructing to cast-in-situ concrete beam slab, can installing first to template bottom beam, then according to the template bottom the beam installed, colligation beam steel, is installing beam two side template and top template.After beam forms has installed, according to the width of beam cross section and the width of cushion block, calculate the length of bearing bar, and calculate the thickness of cushion block, the thickness of cushion block needs to calculate according to actual conditions to determine.When calculating the thickness of cushion block, according to calculating, wherein, the thickness of cushion block is represented; represent top plate thickness, top board is positioned on the stirrup of colligation beam, represents top board upper strata thickness of concrete cover; represent the diameter of stirrup, represent the diameter of described beam upper strata main reinforcement, represent the diameter of bearing bar.The bearing bar determining length is placed, bearing bar of namely slinging under the main reinforcement of beam upper strata under the main reinforcement of beam upper strata.Then to guarantee that protective layer thickness is for principle, and spacing is decided according to the size of beam, several bearing bars of slinging successively.Under bearing bar, side template upper end, top template upper ends cushion block pave described bearing bar.In beam forms and the concreting of top template upper end, make concrete wrap beam steel, corrode to prevent beam steel.It is dismountable beam forms after concrete dries.
The utility model by under cushion block is placed on beam upper strata main reinforcement and bearing bar, such that cushion block is not fragile, displacement.And after form removal, none dew reinforcing bar phenomenon of all beams of building, protective layer thickness evenly and meet the requirements, solves the quality problems revealing reinforcing bar and beam sides dew reinforcing bar at the bottom of beam.
