Because the eyebolt 6 can be dismantled with interior construction platform and be connected, can pull down eyebolt 6 after the handling, prevent that construction footboard 2 top from producing protrudingly, guarantee that constructor normally walks, not receive to stumble.
In order to prevent during the handling that interior construction platform and hollow section of pier 1 from colliding, there is the clearance between interior construction platform edge and the hollow section of pier 1 inner wall, and 2 edges of construction footboard and the hollow section of pier 1 inner wall have the clearance promptly, and the purpose is the collision hollow section of pier 1 inner wall when preventing interior construction platform rebound.
In order to prevent the inner construction platform from shaking when moving upwards, the four sides of the inner construction platform are respectively provided with four limiting idler wheels 9, the number of the limiting idler wheels 9 is four, and the limiting idler wheels 9 are respectively arranged on the four sides of the square tube layer 3. The specific arrangement form of the limiting idler wheels 9 is as follows: the middle parts of the two square pipes 31 positioned at two sides are provided with limiting rollers 9, the length of the square pipe 31 positioned in the middle part is longer, the two ends of the square pipe 31 are provided with steel plates to seal the square pipe, and the steel plates at the two ends of the square pipe 31 are also provided with the limiting rollers 9.
The limiting idler wheel 9 is in contact with the inner wall of the hollow section 1 of the pier, and can roll along the inner wall of the hollow section 1 of the pier, namely, the limiting idler wheel 9 extends outwards and protrudes out of the edge of the construction pedal 2 to be in contact with the inner wall of the hollow section 1 of the pier. Interior construction platform passes through four spacing gyro wheels 9 and 1 inner wall rolling contact of hollow section of pier, can guarantee interior construction platform can be stable smooth shifting up, also avoids bumping.
The inner construction platform is not only lifted upwards, but also can be stably placed in the hollow section 1 of the pier, so that the construction personnel can stand. Therefore, four overturning clamping seats 10 are rotatably arranged below the inner construction platform, the inner construction platform is connected with the hollow pier section 1 through the overturning clamping seats 10, and the inner construction platform is supported through the hollow pier section 1 to be fixed.
When upset cassette 10 was installed, upset cassette 10 was laid to every channel-section steel 41 tip on channel-section steel layer 4, and upset cassette 10 quantity is four, is provided with axis of rotation 11 between upset cassette 10 and the channel-section steel 41 in order to be connected, and then upset cassette 10 can be rotatory for channel-section steel 41 relatively.
Meanwhile, a torsional spring 12 is arranged at the switching position of the turnover clamping seat 10 and the inner construction platform, namely, the torsional spring 12 is sleeved on the rotating shaft 11, one end of the torsional spring 12 abuts against the inner wall of the channel steel 41, and the other end of the torsional spring abuts against the turnover clamping seat 10. Under the effect of torsional spring 12, upset cassette 10 tends to the horizontality all the time, and under this state, upset cassette 10 hugs closely channel-section steel 41 inner wall, and the outside level of extending of upset cassette 10 is outstanding in interior construction platform.
In order to realize being connected of upset cassette 10 and hollow section 1 of pier, pre-buried four draw-in grooves 13 that have at hollow section 1 inner wall of pier, draw-in groove 13 is hollow hexahedron groove structure, draw-in groove 13 adopts the steel to draw-in groove 13 one end opening, draw-in groove 13 open end is inside towards hollow section 1 of pier, so that upset cassette 10 gets into, upset cassette 10 and draw-in groove 13 one-to-one, upset cassette 10 cross-section is less than draw-in groove 13 cross-section.
The turnover clamping seat 10 is matched and clamped with the clamping groove 13, namely, one end of the turnover clamping seat 10 horizontally extends into the clamping groove 13 to be clamped with the clamping groove, and the inner construction platform is arranged in a suspended mode.
The utility model discloses the principle does: and manufacturing an inner construction platform according to the design specification of the hollow section 1 of the pier, wherein the inner construction platform is ensured to be matched with the hollow section 1 of the pier. The pre-buried draw-in groove 13 of the inner wall of the upper end of the pier hollow section 1 which is cast in advance, the inner construction platform is hoisted to the pier hollow section 1 by adopting hoisting equipment, the inner construction platform is kept in a suspended fixed state after the turnover clamping seat 10 is clamped into the draw-in groove 13, a constructor can stand on the inner construction platform to perform operations such as binding steel bars and supporting templates of the pier hollow section 1 of the next stage, the draw-in groove 13 needs to be pre-buried, and preparation is made for hoisting and lifting the inner construction platform again.
1 ligature reinforcing bar of pier hollow section in next stage, prop up and establish the template and pour the shaping after, when preparing to develop the pier hollow section 1 construction in next stage, continue to upwards hoist interior construction platform, the rotatory original draw-in groove 13 that breaks away from of upset cassette 10 this moment, under torsional spring 12 effect, upset cassette 10 tightly supports at 1 inner wall of pier hollow section, under the effect of four spacing gyro wheels 9, interior construction platform can be stable smooth rebound. And after the turnover clamping seat 10 meets the clamping groove 13 again, the turnover clamping seat is clamped with the clamping groove 13, the inner construction platform keeps a suspended fixed state again, and at the moment, constructors can carry out construction operation on the hollow pier segment 1 in the next stage.
Interior construction platform handling removes swiftly, also can realize stable unsettled fixed, can cooperate the creeping formwork to carry out the construction of efficient pier hollow section 1, improves the efficiency of construction.
