Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] The present invention provides an elevator shaft overall lifting formwork device, which includes a core tube 1 with a rectangular parallelepiped structure. The four sides of the core tube 1 are all side plates 10 with flat surfaces. The upright column 22 with a right triangle cross section and the side plate 10 form a cuboid structure with a square cross section. The outer surfaces of two adjacent side plates 10 are respectively flush with the two side faces of the column 22, and the interior of the column 22 is longitudinally provided with some shrinking devices that allow the side plates 10 to move along the inner edge of the column 22, and the bottom of the column 22 It is movably connected with the base 2 of the core tube 1. Below the base 2, there are several claw seats 3 that are connected with the preset latch box 4 inside the wall 6. The claw seats 3 support ...

Abstract

The invention relates to the field of construction and provides an integral lifting type formwork device for an elevator shaft. The device comprises a core tube in a rectangular structure, side boards with wall penetration wire holes are arranged on four lateral sides of the core tube respectively, a vertical column with a rectangular section is arranged at the joint of each two adjacent lateral sides, the lateral side of each vertical column is flush with the surface of the corresponding side board, a plurality of contraction devices enabling the side boards to move along the inner sides of the vertical columns are arranged inside the vertical columns, the lower portion of each vertical column is in movable connection with a base of the core tube, a plurality of claw seats in matched connection with latch boxes preset in walls are arranged below the base, and the claw seats in a horizontal state support the base and are in downwardly rotatable connection with the base. Arbitrary beam length adjustment in a certain range is realized, and convenience in adjustment and reusability are achieved; when the integral lifting type formwork device is used for establishing of a formwork platform, the formwork platform is enabled to be adjustable in size to adapt to construction of cylindrical cast-in-situ shear wall formworks different in section size; after construction is finished, the device can be lifted upwards to be directly used for construction of the elevator shaft at a lower storey, technical performances are promoted, construction efficiency is greatly improved, and reusability is achieved.

Description

technical field [0001] The invention relates to the construction field, in particular to an elevator shaft integral lifting formwork device. Background technique [0002] In building construction, it is common to encounter tube-type cast-in-place shear walls of various shapes and cross-sectional sizes, such as tube-type cast-in-place shear walls for elevator shafts. When installing the formwork, it is necessary to lap the formwork platform inside the tube, which is more common The best method is to use steel pipes, fasteners, wooden boards, etc. for lap joints. This traditional lap joint method requires a lot of consumables, labor and time, and cast-in-place shear walls of different shapes and cross-sectional sizes require lap joints of different specifications and quantities. Parts are not only costly, but also heavy workload, and the simple platform built has great potential safety hazards. Contents of the invention [0003] In order to solve the problems of labor-inten...
