Among two adjacent strutting arrangement, when the interior steel reinforcement frame of construction bent cap template, the stability of two strutting arrangement is increased to multiplicable tie bar or extension roof beam.
When the supporting device is used, the cross support beam and the motor support frame are connected together by using the bolt pair, and then the cross support beam and the support leg are fixedly connected by using the bolt pair. And integrally lifting the assembled template dismounting device to the top surface of the pier, and anchoring the template dismounting device on the pier through pre-buried finish-rolled deformed steel bars. When carrying out the promotion of bent cap template, only need can accomplish the promotion of bent cap template and the promotion of reinforcing bar material, instrument through bent cap template dismouting equipment, convenient to use has avoided tower crane or crane to stop near the pier stud operation for a long time. And the supporting legs and the cross bracing beams in the dismounting device can be used as supporting structures of the dismounting device and can also be used as keels of the cover beams. After pre-buried in the bent cap, convenience when can improving the dismantlement of template dismouting equipment can also improve the structural strength of bent cap moreover, reduces the construction of the steel reinforcement fossil fragments originally of bent cap. The whole structure is simple and novel, and the innovation is high.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
Parts which are not described in the invention can be realized by adopting or referring to the prior art.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art may make modifications, alterations, additions or substitutions within the spirit and scope of the present invention.
