Detailed Description
The present invention will be further described with reference to the following examples.
As shown in fig. 1, a cast-in-place concrete floor slab structure slab-descending construction mold comprises a rectangular main frame structure formed by angle steels 2, wherein the structure is used for accommodating cast-in-place concrete; the outside of main frame structure is equipped with hangs mould location reinforcement muscle 1, mainly plays supporting role to convenient hoist and mount, the hypotenuse opening of angle steel 2 is by 3 welding closing caps of steel sheet, makes it form a firm triangle-shaped, and the structure is reliable, and the inside length of a side direction along two limits of rectangle of main frame is provided with steel bar support 4, and these supports will bury underground inside the concrete, every hang the bottom of mould location reinforcement muscle 1 and still be equipped with reinforcing bar protective layer cushion.
Example (b):
the utility model provides a cast-in-place concrete floor structure falls board construction mould which characterized in that: including the rectangle main frame structure who constitutes by angle steel 2, main frame structure's the outside is equipped with and hangs mould location reinforcement muscle 1, and the hypotenuse opening of angle steel 2 is provided with steel bar support 4 by steel sheet 3 welding closing caps along the length of side direction on two limits of rectangle inside the main frame, every hang the bottom of mould location reinforcement muscle 1 and still be equipped with reinforcing bar protective layer cushion.
Further, the specification of the angle steel is L50 multiplied by 32 multiplied by 3.
Further, the thickness of the steel plate is 2 mm.
Further, the reinforcing steel bar support adopts a reinforcing steel bar with the diameter of 16 mm.
Further, the steel plate is 120 degrees with the horizontal plane when covering the angle steel.
The construction method of the scheme is as follows:
the template is hung according to the preparation of structure decline board height and geometric dimension earlier, and the template forms wholly by angle steel splice welding, and angle steel L type opening hypotenuse adopts 2-3mm steel sheet welding tight, forms the triangle-shaped cross-section, and the triangle-shaped hypotenuse is as hanging the binding face of mould and concrete, and the way is one like this: the internal corner of the falling plate can be formed into a structural chamfer at one time after the concrete pouring is finished, so that the direct construction of the next procedure is facilitated, and a secondary construction chamfer is not needed; secondly, the following steps: the hanging mould is in an inverted triangle shape, the upper part is wide, the lower part is narrow, and the template is easy to disassemble; thirdly, the method comprises the following steps: the plane at the upper part of the hanging mould is used as a control point of the top elevation of the floor slab, and is used as a hanging bar supporting surface for leveling the peripheral floor surface when concrete is poured. In order to ensure the integral rigidity of the steel hanging die, a reinforcing steel bar support is arranged in the middle of the die plate, a reinforcing steel bar with the diameter of 16 is preferably adopted, the support interval is about 1.5 m, and the steel hanging die and the reinforcing steel bar support are firmly welded into a whole. Before the hanging mould is installed, positioning steel bars are arranged on the periphery of the hanging mould, the positioning steel bars are made of two steel bars with the diameter of 12 mm, the positioning steel bars are formed by cross welding, one ends of the horizontal steel bars and the outer side beam ribs or the plate ribs of the hanging mould are welded to control the elevation, the other ends of the horizontal steel bars serve as hanging mould placing points, the bottoms of the vertical steel bars are arranged on cushion blocks on the lower portion of a concrete floor, the upper portions of the vertical steel bars and the hanging mould are connected to control the plane position, the middle portions of the vertical steel bars and the. Removing the hanging mould: after the concrete is finally set, two ends of the middle supporting steel bar of the hanging mould are used as lifting points, the two symmetrical stations are lifted vertically at the same time, and the hanging mould is integrally dismantled.
