Detailed Description
The invention is described in further detail below with reference to the following figures and examples:
referring to fig. 1-4, an elevator shaft lifting type construction steel platform comprises two triangular support frames 1, a steel platform 2 and support legs 5, wherein the steel platform 2 uses channel steel as a main beam, a secondary beam 7 is arranged at the interval of every 300mm of the main beam, a pattern steel plate 3 is welded on the steel platform, and four lifting rings 4 are welded on the main beam of the steel platform; two triangular support frames 1 are welded below the main beam of the steel platform, the vertical edges of the two triangular support frames 1 are connected into a whole through a plurality of steel pipes, the vertical edge extending parts of the triangular support frames 1 are support legs 5, the outer sides of the support legs 5 are respectively welded with transverse short channel steel 6, and the protruding parts of each support leg support the upper opening of the elevator shaft door opening and are fixed.
And the steel platform main beam is welded by adopting 14# channel steel.
The secondary beam 7 is a square rectangular tube with the thickness of 50mm multiplied by 50mm and the thickness of 4 mm.
The triangular support frame 1 is welded by 20# channel steel.
The lifting ring 4 is formed by welding reinforcing steel bars with the diameter of 20 mm.
The patterned steel plate 3 is 5mm thick, and each side except the opposite side of the elevator opening is provided with a 200mm wide turning plate.
The length of the transverse short channel steel 6 is 200mm, and the distance from the transverse short channel steel to the bottom is controlled to be 200 mm-250 mm, so that an L shape is formed.
Two triangular support frames are adopted, and the operation platform frame body is assembled by using a transverse support. Elevator shaft triangle steel platform lower part L type landing leg card is unanimous to the one deck floor face under the construction layer, and the width is unanimous with the elevator door opening, and upper portion operation platform card adopts the wooden wedge to fix on the bracket channel-section steel that the shear force wall was reserved, forms stable supporting platform. And fixing steel plates on the platform frame body in a welding mode to form a tool type operation platform, and adjusting the construction platform in the elevator shaft according to different elevator shaft sizes.
The construction sequence is as follows: tripod manufacturing → tripod hoisting → upper frame body installation → structure construction → dismantling (or hoisting out) the steel pipe frame → lifting the tripod.
Hoisting a section steel tripod: the steel platform is installed from two layers and used in a circulating way towards the upper layer by layer. When the steel platform is hoisted, the platform is slightly lifted into an elevator shaft by a tower crane at a certain angle, one end of the lower part of the triangular support with the short-groove steel support is arranged on one side of an elevator shaft door, and when the short-groove steel support blocks the lower edge of an elevator door opening, the operating platform is slowly leaned on the elevator shaft wall. Four steel ropes of the lifting platform device are slightly longer than two steel ropes close to the triangular short support, so that the platform device is convenient to place. When the shear wall and beam column concrete in the elevator shaft reach the strength requirement, the side mold can be detached for platform hoisting. When the steel platform is hoisted, four hoisting points are required to be respectively hung with ropes, and are hoisted simultaneously, and one or two steel wire ropes are strictly forbidden to pass through the hoisting ring for hoisting.
Lifting an elevator shaft operating frame: lifting the whole elevator shaft operating platform layer by layer, wherein the whole elevator shaft operating platform is positioned at one layer below a construction layer; when the elevator shaft construction operation frame is lifted, the upper frame body is firstly dismantled, when the fixed channel steel at the bottom of the support is clamped on the upper beam, only the other side is lifted, when the frame body passes through the clamping part, the lower part of the frame body is fixed on the beam when reaching the specified part, and the frame body is stably placed.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any form, and any simple modification, equivalent change and modification made by the technical spirit of the present invention to the above embodiments do not depart from the technical solution of the present invention.
