[0002] The large formwork of existing construction projects is usually an assembled or integral large formwork welded by steel panels, steel ribs, etc., which is only suitable for the construction of vertical structure cast-in-place concrete projects. The resource investment is large, and the plane formwork still adopts various forms such as small steel formwork and wood formwork during construction, which makes the construction process of formwork engineering more complicated and has not been widely used in many areas; currently, formwork engineering generally adopts multi-layer glued buildings The wooden formwork is used as the panel, and the square wood is used as the rib. During construction, the panel is assembled piece by piece on site and nailed to the square wood ribs one by one with iron nails. When dismantling, the square wood ribs are removed one by one and then the panel is removed , the deviation of panel joints is large, the construction work is heavy, the amount of iron nails is large, and the loss of panels and square timber is large

Embodiment Construction
[0013] from figure 1 , figure 2 It can be seen from the figure that: a large wooden formwork construction technology is characterized in that the large wooden formwork on the outside of the shear wall outer cylinder is mainly composed of panels (1), ribs (3), beams (2), rings (5) and Reinforcement system, panel (1) is rectangular in plane, made according to the height of the shear wall floor and the length of the outer side section, the panel (1) is assembled by butt jointing of several multi-layer glued building wooden formwork, the rib (3) vertical Close to the back of the panel (1) and nail the panel (1) and the rib (3) firmly with iron nails. The length of the rib (3) is greater than the height of the panel (1) and protrudes from the panel (1) up and down. Several ribs ( 3) The vertical sides parallel to the panel (1) are evenly arranged according to a certain distance, and there is one beam (2) at the top and bottom, which is equal to the length of the panel (1), and th...

The invention discloses a big wood formwork. The big wood formwork on the outer side of an outer barrel of a shear wall mainly consists of a panel (1), ribs (3), crossbeams (2), hoisting rings (5) and an oppositely pulling and reinforcing system. By the aid of construction technology for the big wood formwork on the outer side of the outer barrel of the shear wall in building engineering, the big wood formwork is manufactured in a processing field, joints of the panel are close, and the big wood formwork is simple in process, convenient in operation, high in work efficiency and low in loss of materials, is safe and reliable, and effectively reduces construction cost.
Description
technical field [0001] The invention belongs to a formwork for construction engineering and a manufacturing method thereof, in particular to a large wooden formwork on the outer side of an outer cylinder of a shear wall of a construction engineering and a manufacturing method thereof. Background technique [0002] The large formwork of existing construction projects is usually an assembled or integral large formwork welded by steel panels, steel ribs, etc., which is only suitable for the construction of vertical structure cast-in-place concrete projects. The production cost of large formwork is high, and transportation, storage and repair The resource investment is large, and the plane formwork still adopts various forms such as small steel formwork and wooden formwork during construction, which makes the construction process of formwork engineering more complicated and has not been widely used in many areas; currently, formwork engineering generally adopts multi-layer glued ...
