After binding the steel bars, fix them in the aforementioned mold; 3. Add concrete to wait Dry; 4. Demould and take out the finished product.

However, the aforementioned shortcomings are that, if structures such as wall panels are to be overlapped, additional construction components are required, such as connecting steel bars, and additional positioning work is required, which is quite troublesome and complicated.

How to improve the aforementioned problems is a subject actively handled by the relevant industry.

The main purpose of the present invention is to provide a method for manufacturing frame-type concrete slabs. Through a frame of a predetermined shape, a plurality of steel bars are arranged inside the frame, and concrete (cement) is poured into the space of the frame. A concrete slab with a frame can be formed; because the frame is a mold, there is no problem of demoulding; and the frame can prevent collision.

Another object of the present invention is to provide a frame-type concrete slab, characterized in that: a frame-type concrete slab is surrounded by a frame, and the frame can define two parallel horizontal sides and two parallel vertical sides. The horizontal side and the vertical side remain vertical; further, the steel bars in the frame-type concrete slab pass out of the frame, and a plurality of frame-type concrete slabs are integrated by welding.

Another object of the present invention is to provide a building structure overlapped by frame-type concrete slabs, which is assembled with a plurality of frame-type concrete slabs, wherein every two frame-type concrete slabs are arranged between There is a supporting beam with a plurality of connecting pieces corresponding to the steel bars that pass through the frame. The steel bars passing through the frame-type concrete slab are welded to the connecting pieces on the supporting beam, so that the frame The concrete slab maintains toughness, better wind resistance and shock resistance.

Therefore, the technical features of the present invention can be understood through the above description:

1. The manufacturing method of the present invention can avoid the peeling of the edge of the concrete slab caused by demoulding, or can prevent the chipped corner caused by collision.

2. The frame-type concrete slab provided by the present invention is characterized by a flat structure. When combined through a supporting beam, the flatness of each joint can be maintained, and no additional processing is required to fill the gap.

In the best implementation, the frame (1) can be shaken to make the concrete (3) It can be compacted, and the surface will be leveled after being filled with concrete (3). Among them, when there is a demand for surface modeling, a modeling structure such as a mold can be used in the surface leveling process to make the finished product after forming have a predetermined pattern or shape.

Step 4: Wait for the concrete (3) to dry to obtain a framed concrete slab (A), which can be stored or sent to the construction site for assembly.

Because the metal frame (1) can protect the concrete (3), even if it collides during transportation or assembly, it will not cause unsightly problems such as chipping and corners as conventionally used; furthermore, the present invention does not require demoulding The process can save the cost and time of demolding.

In addition, the frame (1) can overlap different shapes. Compared with the conventional structure, this case not only does not need to spend additional mold costs, but also reduces manufacturing costs and improves durability.
