Problems solved by technology

[0002] At present, in the construction of the cast-in-situ walls of elevator shafts in high-rise buildings, large formwork composed of bamboo (wood) plywood and steel pipe scaffolding are widely used. The turnover materials and labor input are large, and the size of the shaft is prone to deviation. The construction speed is slow and the work efficiency is low.

Embodiment 1

[0033] Example 1: A hoistway model system for lifting elevators, such as Figure 1-1~Figure 3-2 As shown, the hoisting elevator hoistway mold system includes a hoisting frame, a combined hoistway mold, and a hoisting device. The hoisting frame is composed of a base load-bearing beam 1, a main beam 2, a secondary beam 3, a column 4, an intermediate beam 5, and a diagonal brace. 6. The frame type operating platform composed of the top beam 7 and the climbing ladder 8. The lifting frame adopts the load-bearing high-strength bolts 16 and the embedded high-strength nuts on the elevator shaft wall through the reserved holes 13 on the connecting plate 12 at the end of the load-bearing beam 1 17 Connect to fix the hoisting frame on the elevator shaft wall;

[0034] The combined hoistway mold includes a large steel template 18 and a female corner die 19. The template panel of the steel large template 18 is made of steel plate, the vertical flute 20 is made of channel steel, and the horizo...

Embodiment 2

[0039] Embodiment 2: A method for construction of cast-in-place walls of elevator shafts.

[0040] The method is to use the elevator hoistway mold system described in the first embodiment to carry out the construction of the cast-in-place wall of the elevator hoistway. During the hoisting construction, the steel large template of the combined hoistway mold and the hoisting frame are mutually supporting points, and the hoisting frame It is lifted into place as a whole with the large steel formwork, and lifted once every floor is completed; it includes the following steps:

[0041] A. Hoisting frame approach installation: use a tower crane or truck crane to hoist the hoisting frame into the elevator shaft, adjust the length of the base bearing beam 1 extending into the main beam 2, and install a limit pin 15 through the pin hole 14 to limit the position, and then pass the base The reserved holes 13 on the end connecting plate 12 of the load-bearing beam 1 are connected with the pre-...

Abstract

A system for lifting an elevator shaft mold comprises a lifting frame, a combined shaft mold and a lifting device, wherein the lifting frame is a frame type operation platform which is formed by a base bearing beam, a main beam, a sub beam, an upright, a middle layer beam, a diagonal bracing, a top layer beam and a climbing ladder; through a reserved hole in a bearing beam end part connecting plate, the lifting frame is fixedly connected to an elevator shaft wall by using bearing high-strength bolts and embedded high-strength nuts which are formed on the elevator shaft wall; the combined shaft mold comprises a big steel template and an internal corner mold; through a side end vertical edge channel steel, the big steel template and the internal corner mold are fixed by using assembling bolts and reinforced by internal corner mold hook bolts to form an integral combined shaft mold; through a reserved hole in the lower part of the big steel template, the combined shaft mold is fixed on the elevator shaft wall by using a supporting lug bolt and embedded nuts which are formed on the wall; and the lifting device comprises lifting hoists and inverted hooks. During construction, the lifting hoists are mounted with the big steel template and the lifting frame as a supporting point of one another, so as to lift the lifting frame and the big steel template in sequence; and the lifting frame and the big steel template are lifted when every layer is constructed. The system for lifting the elevator shaft mold, provided by the invention, can be integrally assembled and disassembled and is convenient in construction.

Description

Technical field [0001] The invention relates to a template and a hoisting frame in building construction and a method for constructing a cast-in-place wall, in particular to a hoisting elevator hoistway mold system and a method for constructing a cast-in-situ wall of an elevator hoistway. Background technique [0002] At present, large formwork composed of bamboo (wood) plywood and steel pipe scaffolding are widely used in the construction of cast-in-place walls of elevator shafts in high-rise buildings. The turnover materials and labor input are large, the shaft size is prone to deviation, the construction speed is slow, and the work efficiency is low. Summary of the invention [0003] The object of the present invention is to provide a hoisting elevator hoistway mold system and a method for the construction of the cast-in-place wall of the elevator hoistway. When the hoisting elevator hoistway mold system is used for the construction of the elevator hoistway cast-in-situ wall, th...
