Problems solved by technology

However, large-scale brick tire formwork masonry has a long construction period, a large amount of labor input, many objective factors affecting the construction period, and it is difficult to control the construction period and cost.
During the construction of the foundation pit, the use of ordinary brick tire formwork to build caps and ground beams requires a large amount of bricks, and the frequency of use of tower cranes increases. The materials are not easy to be stacked and placed, and it is difficult to manage safety; a lot of manpower

Embodiment Construction

[0026] A PC prefabricated board instead of traditional brick tire form construction method, comprising the following steps:

[0027] (1) Construction preparation

[0028] 1) The construction personnel carefully examine the drawings, and clearly understand the relationship between the size of the foundation beam and the elevation, position and axis of the cap;

[0029] 2) Make a written disclosure of technical and safety operations to the professional operation team, and confirm with the signatures of both parties.

[0030] 3) Set out the construction line and place the setting position on the cushion layer;

[0031] (2) Installation of prefabricated panels

[0032] 1) Cut the prefabricated slab raw materials according to the size and specifications of the on-site cap or ground beam;

[0033] 2) Place and initially fix according to the setting-out position of the construction site;

[0034] (3) Connection and fixation of prefabricated panels

[0035] 1) The installation me...

Abstract

The invention discloses a construction method with a PC prefabricated slab replacing a conventional brick tire mold. The construction method comprises the following steps of construction preparation,prefabricated slab mounting, prefabricated slab connecting and fixing, inner side supporting, backfilling construction and the like. The construction method can guarantee rigidity, strength and stability of a formwork effectively. Compared with a conventional construction method, a lot of funds can be saved.

Description

technical field [0001] The invention relates to a PC prefabricated board construction method. Background technique [0002] Brick tire mold is a form of formwork system. Brick tire formwork itself is not an integral part of the engineering entity. It is mainly used in the basement caps of buildings in the form of raft foundations, elevator shafts, raft edges, ground beams and other parts where side forms cannot be removed. However, large-scale brick tire formwork masonry has a long construction period, a large amount of labor input, many objective factors affecting the construction period, and it is difficult to control the construction period and cost. During the construction of the foundation pit, the use of ordinary brick tire formwork to build caps and ground beams requires a large amount of bricks, and the frequency of tower cranes is increased. The materials are not easy to be stacked and placed, and it is difficult to manage safety; A lot of human input. Contents ...
