Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Please refer to fig. 1-3, which is a device for reserving and transferring material ports of a prefabricated composite slab according to the present invention, comprising a fixing frame 1 and a reinforcing beam 2.
The fixing frame 1 is a quadrilateral frame, the height of the frame is 5cm-6cm, the height of the frame is matched with the thickness of the superposed plate, when the prefabricated plate fixing frame is used, the fixing frame 1 is embedded into the prefabricated plate, and the outer surface of the fixing frame 1 is in contact with the outer surface of the prefabricated plate.
The edge of the frame opening of the fixed frame 1 horizontally extends outward to form a lap joint table 3, and the lap joint table 3 is perpendicular to the side surface of the fixed frame 1.
The lapping table 3 is used for stably clamping the reserved material conveying port device on the precast slab.
The outer edge of the lapping table 3 extends outwards in an inclined way, and then a limiting frame 4 is formed above the lapping table 3.
The limiting frame 4 and the upper surface of the lapping table 3 form an included angle of 135-120 degrees, so that the limiting frame 4 is in an inverted trapezoid shape.
In the pouring process, the limiting frame 4 is used for limiting the shape of the material conveying opening, so that the material conveying opening forms an inverted trapezoid.
The inverted trapezoidal material conveying port device is easier to disassemble, and can avoid damaging the concrete around the device.
When sealing and pouring are carried out after construction is finished, the inverted trapezoidal material conveying port has a certain gradient due to the inner wall of the inverted trapezoidal material conveying port, so that fluid materials are more easily sunk to the bottom of the material conveying port under the action of gravity, pouring is easier to carry out, and pouring blind spots are not easy to generate.
The height of the limiting frame 4 is 6cm-7cm, and the height requirement of the concrete layer is met.
At least two pairs of avoidance bar holes 5 are symmetrically formed in two side faces of the fixed frame 1, and a scheme of four pairs of avoidance holes is adopted in the embodiment.
One end of the avoidance bar hole 5 extends downwards and penetrates through the fixed frame 1, and the other end extends to the side face of the limiting frame 4 through the lapping table 3 but does not penetrate through the limiting frame 4.
The avoidance bar holes 5 on the same surface are arranged at equal intervals, and the distance between the avoidance bar holes is the same as that between the steel bars in the prefabricated slab.
Dodge the reinforcing bar in the prefabricated plate of strip hole 5 mainly used, in the use, the reinforcing bar restriction of prefabricated plate is dodging strip hole 5, just so can remain the reinforcing bar in the prefabricated plate for can use the reinforcing bar of length unanimity in the work progress, and saved the bar planting process, saved construction material, improved the efficiency of construction.
The reinforcement beam 2 includes a first reinforcement beam 21 and a second reinforcement beam 22, and the first reinforcement beam 21 and the second reinforcement beam 22 are disposed between adjacent breaker bar holes 5.
The first reinforcing beam 21 is arranged in the fixed frame 1, and two ends of the first reinforcing beam are fixedly connected with two side surfaces of the fixed frame 1 in a welding mode.
The second reinforcing beam 22 is arranged in the limiting frame 4, and two ends of the second reinforcing beam are fixedly connected with two side surfaces of the limiting frame 4 in a welding mode.
The first reinforcing beam 21 and the second reinforcing beam 22 are respectively used for reinforcing the fixed frame 1 and the limiting frame 4, so that the structure of the fixed frame is more stable, and meanwhile, the second reinforcing beam 22 can also serve as a stress point during demolding.
The using method comprises the following steps:
firstly, placing a reserved material transfer port device in a precast slab, placing a steel bar of the reserved material transfer port in an avoidance bar hole 5, overlapping a lapping table 3 on the upper surface of the precast slab, and binding the steel bar of a cast-in-situ floor slab layer;
secondly, pouring the precast slab, and limiting the shape of the material conveying port to be an inverted trapezoid by a limiting frame 4;
thirdly, demolding the reserved material conveying port device after the pouring material is dried and formed;
thirdly, cutting short and bending the reinforcing steel bars at the material conveying opening to carry out material conveying construction;
and finally, after the construction is finished, bending and resetting the reinforcing steel bars, and pouring and sealing the material conveying port after welding connection.
The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described.
