(1), because the mechanics bearing capacity of steel pipe self, when the support body height surpassed 50m, support body stability was insecure, and certain potential safety hazard is arranged;
(2), construction period of general highrise building is longer, steel pipe adopts lease more, the holding time of tube material is longer, the rent of steel pipe is bigger, is unfavorable for the saving of engineering cost;
(3), to set up scaffold cumbersome, expends time in, and prolonged the duration virtually.
Summary of the invention
Deficiency at the prior art existence, technical problem to be solved in the utility model is, provide a kind of simple in structure, effectively ensure workman's construction safety, can make the guaranteed elevator shaft A-frame of the Forming Quality formula formwork platform of elevator shaft shear wall again.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of elevator shaft A-frame formula formwork platform, comprise that a side and lower floor build the shear wall clamping of finishing, opposite side and lower floor build the rectangular platform grillage of the floor clamping of finishing and are located at platform surface layer on the rectangular platform grillage, it is characterized in that: described elevator depth direction is extended with vertical support bar to lower floor in rectangular platform grillage upper edge, described vertical support bar top is connected with the rectangular platform grillage, the bottom with build the floor support and connection of finishing, between vertical support bar and rectangular platform grillage, be provided with can and described rectangular platform grillage and vertical support bar between the oblique support bar of formation triangular support structure, the upper surface of described rectangular platform grillage extends upward the second formwork support bar is set.
Above-mentioned elevator shaft A-frame formula formwork platform, described vertical support bar is provided with two along rectangular platform grillage width perpendicular to the rectangular platform grillage.
Above-mentioned elevator shaft A-frame formula formwork platform, described oblique support bar are connected with two vertical support bars and near the rectangular platform grillage of building shear wall one side of finishing respectively.
Above-mentioned elevator shaft A-frame formula formwork platform, described vertical support bar bottom links to each other with oblique support bar bottom, is located in the end of oblique support bar bottom with described lower floor and builds the adaptive angle member of finishing of floor right angle portion.
Above-mentioned elevator shaft A-frame formula formwork platform is provided with reinforcing rib between described oblique support bar and rectangular platform grillage and the vertical support bar.
Above-mentioned elevator shaft A-frame formula formwork platform, the described second formwork support bar is provided with four, is located at respectively on four angles of rectangular platform grillage.
Above-mentioned elevator shaft A-frame formula formwork platform, described rectangular platform grillage is provided with suspension ring.
The advantage of the utility model elevator shaft A-frame formula formwork platform is: this formwork platform has used leg-of-mutton stability principle, body of wall that utilizes lower floor to build to finish and floor are as the support of platform, lay plank in table top, operating personnel stand in and carry out formwork erection on the platform.The utility model formwork platform operations safety installs simply, can not exert an influence to member on every side, has reduced material usage, has improved operating efficiency and quality greatly.
