Example Embodiment
[0039] Example one see Figure 2-4 As shown, the general length of the double-layer connecting beam is: 1800mm, 2400mm, 3200mm, 3300mm, etc. The length of the double-layer connecting beam opening that requires formwork is less than 3m. This double-layer connecting beam opening template system includes an opening template and a template support. The opening template includes a frame body 1 and a frame backing 2. The frame The body is supported in the opening of the double-layer connecting beam and is adapted to the size of the double-layer connecting beam opening, including at least the upper side plate 1.1, the lower side plate 1.2, the left side plate 1.3 and the right side plate 1.4. The opening template also includes At least one lower ash vibrating drum 3 is provided inside the frame body, which vertically penetrates the upper side plate and the lower side plate.
[0040] The upper side plate 1.1 has an upper opening 1a, and the lower side plate 1.2 has a corresponding lower ...
Example Embodiment
[0044] See the second embodiment Figure 6-7 As shown, the difference from the first embodiment is that the length of the double-layer connecting beam opening that needs to be supported is greater than 3m. In order to ensure the appearance and structural quality of the concrete after casting and mold removal, the lower ash vibrating drum 3 is set at least Two, three are set in this embodiment, with a spacing of 0.75m, and are arranged in a straight line along the length of the double-layer connecting beam.
[0045] The frame of the present invention can also be provided with a front side plate and a rear side plate to form a box body.
[0046] The construction methods of the above two double-layer connecting beams using the double-layer connecting beam portal formwork system are as follows:
[0047] Step one is to bind the double-layer connecting beam reinforcement 7 and the column reinforcement 8 of the structural columns on both sides of the double-layer connecting beam.
