Description

[Detailed description of the invention] Arrangement of tiltable formwork for casting A tiltable formwork for tilting a wall such as a wall to an upright vertical position. Concerning the array of.

Concrete wall construction usually involves hanging the wall unit where it is to be ultimately positioned. This is done on the construction site by installing straight wall boardwork. This technique is extremely Shiny and pouring pressure at the bottom edge of the wall unit easily pushes the form outward. Since it is compressed, the stability of the formwork is strictly required. Thus, this formwork is closely It must be reinforced by a set of planks that are placed horizontally; otherwise, the Lifting equipment that requires the use of a crane or similar type of lifting device. ゛Steel formwork may also be used. Watertightness of formwork in both horizontal and vertical directions There are also strong demands. Very slight changes that normally occur at formwork joints would require expensive post-processing in the form of grinding and/or filling.

One method to solve these problems is commonly called the "tilt-up method." Ru. This method involves casting the wall in a horizontal position and then This means that the number wall is raised together with the formwork to the intended vertical position. This technique is advantageous in that problems associated with pouring pressure and vertical formwork seams are resolved. be. In addition, we have successfully achieved pour molding for the horizontal floor structure. As a result, the casting operation is substantially facilitated. i.e. mineral condensation Cavities are formed by cavities or along the surface of formwork without adhering to objects It is often difficult to obtain an acceptable surface for two surfaces with considerable height. It is necessary to press concrete between wall panel members that are placed closely together. will disappear.

When pouring is carried out in winter, there is also one obvious advantage inherent in horizontal pouring. You can get it easily. Horizontal frames are easily enclosed and heated from below.

The ``tilt-amplifier method-1'' that has been used up until now is a method in which the formwork is poured horizontally after the formwork is removed. The molded wall is raised into position by mechanical lifting devices or including tilting to a vertical position before the frame is removed. This latter The method does not require the use of special lifting equipment such as a crane or similar type of lifting equipment. Therefore, it is preferable. This wall positioning is independent of other mechanical aids and This can be achieved directly by the frame. Horizontal formwork from horizontal to vertical position Devices for tilting are described, for example, in U.S. Pat. No. 1.1-48,246, No. 1. '7 No. 73,454 and No. 1,668,300, Germany's Permit No. 828,588 and Swedish Patent No. 103.951.
