In institute's drawings attached, identical label is indicated similar or corresponding feature or function.
The specific embodiment
Below with reference to accompanying drawing, specific embodiment of the utility model is described in detail.
Fig. 1, Fig. 2, Fig. 3 and Fig. 4 are respectively steel bar framework of box beam colligation die cut view, side view according to the utility model embodiment, overlook analysis diagram and top view.As shown in Figure 1, Figure 2 and Figure 3, the steel bar framework of box beam colligation mould that the utility model provides, comprises base 1, angle steel and some (at least four) column 2.
Wherein, base 1 is comprised of two steel plates that are parallel to each other, and steel plate is formed by the Plate Welding of at least two bar shapeds, between two steel plates that are parallel to each other, every certain distance, is welded with one reinforcing bar or steel plate.
On base 1, according to case beam steel position, be provided with anchor point (not marking) on figure; Anchor point can adopt thinner reinforcing bar (than the thin reinforcing bar of Φ 22 reinforcing bars) to be welded on base 1, to guarantee firmly not deforming of anchor point.
Angle steel and the mutual correspondence of column 2 are arranged on the both sides of base 1.Between column 2 and base 1, adopt some Φ 22 reinforcing bars 5 to be connected; The upper end of column 2 and angle steel welding, the lower end of column 2 is goed deep into ground and is fixed.Wherein, column 2 adopts Φ 22 reinforcing bars, and the spacing between every two root posts 2 is default spacing (being generally 3 meters of left and right).By this form of construction work, bar spacing is even, quantity is fixed, and easy and simple to handle, framework of steel reinforcement Forming Quality is high, and intensity, rigidity and stability increase, and can improve the beam prefabricated quality of case.
In the utility model, angle steel is comprised of right angle angle steel 3 and 4 two kinds of angle steel of triangle angle steel; The upper end of right angle angle steel 3 and column 2 is by being welded and fixed; Triangle angle steel 4 is arranged on a side that is welded with right angle angle steel 3 on column 2 with preset angles, the upper end of triangle angle steel 4 and right angle angle steel 3 are by being welded and fixed, and the lower end of triangle angle steel 3 is fixedly connected with the reinforcing bar that base 1 is connected with column 2.
The utility model is in specific embodiment, and steel bar framework of box beam colligation mould material therefor is building site common steel, comprising: Φ 22 reinforcing bars, angle steel, steel plate and on a small quantity other model reinforcing bar; In whole process, all can adopt gas welding cutting, material junction adopts arc welding to connect.
In steel bar framework of box beam colligation mould work progress of the present utility model, need a large amount of reinforcing bars, in reinforcing bar process, need to be in conjunction with case beam designing requirement cutting rebar sizes, to meet the design and construction requirement of case beam, then the materials such as the reinforcing bar of well cutting and angle steel, steel plate could be welded.
Wherein, base 1 is comprised of two steel plates that are parallel to each other, and each steel plate is welded by the bar steel plate of a plurality of 20 centimetres of left and right width, welds one Φ 22 reinforcing bar or steel plate between the steel plate being parallel to each other every the distance of about 3 meters.
The size of base 1 is welded according to case beam base plate size, base 1 because of length long, width between two parallel steel plates is not easy to guarantee, so every 3 meters of left and right one Φ 22 reinforcing bar of welding or steel plate in the middle of base 1, to guarantee that the width of base 1 reaches design standard.
And, on the front of base 1, according to case beam steel position, being welded with anchor point, anchor point adopts thinner steel bar welding to be connected on base 1, to guarantee that anchor point does not firmly deform.
As shown in above-mentioned each figure, in the both sides of base 1, be provided with angle steel and some columns 2 of mutual correspondence.
