In the above embodiment, the triangular truss 200 has the support ribs 240 at both ends. Specifically, the arched triangular truss 200 is hoisted to the mounting beam and then welded, and because the triangular truss 200 is arched, two ends of the lower chord 220 form a certain included angle with the horizontal plane, and therefore only the end point of the end of the lower chord 220 is in contact with the mounting beam. At this moment, the welding is carried out at the contact point, and the welding spot is smaller, so that the whole stability of the floor bearing plate is lower. Therefore, in order to increase the welding area, the support ribs 240 are fixedly connected to both ends of the triangular truss 200, and the support ribs 240 are welded to the mounting beam to fix the triangular truss 200.

Specifically, the middle part of the screw 110 is welded with a rotating rod 113 along the radial direction, the axis of the rotating rod 113 is perpendicular to the axis of the screw 110, and when the screw 110 needs to be rotated, a worker can directly pull the rotating rod 113 along the circumferential direction of the screw 110.

It should be noted that the size of the rotating rod 113 can be determined according to actual requirements.

On the basis of the above embodiment, the screw 110 is welded with a plurality of rotating rods 113 along the circumferential direction. Specifically, as in the above embodiment, the plurality of rotating holes 111 function in the same manner, and when it is difficult for one person to rotate the screw 110, a plurality of persons can apply force simultaneously by using the plurality of rotating rods 113.

In addition, the worker may arbitrarily replace the force-receiving rotating rod 113 to optimize the force-receiving angle, so that it is easier to rotate the screw 110.

In some embodiments, upper chord 210 and lower chord 220 are steel tubes, and upper chord 210 and lower chord 220 can increase stiffness due to the concrete poured into the tubes.

Specifically, in order to further reduce the manufacturing cost, steel pipes may be used as the upper chord 210 and the lower chord 220 of the triangular truss 200, and after the triangular truss 200 is arched, concrete is poured into the upper chord 210 and the lower chord 220, and it can be understood that the solidified concrete can increase the rigidity of the upper chord 210 and the lower chord 220 to increase the bearing capacity of the floor deck.

It should be noted that, before concrete pouring, a baffle plate needs to be fixed around the triangular truss 200 so as to shape the floor deck. In addition, the building carrier plate upper surface still need be made level when pouring to satisfy the building carrier plate in-service use demand.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
