Description

one

The invention relates to the field of construction of structures, tanks, in particular, to iKO, HCTpyiKUHHM formwork cabins for building walls.

Known are slides for concreting of the linear and horizontal walls of a constant radius of curvature, including carcass with shield panels with studs and tightening screws.

The purpose of the invention is to ensure the erection of the walls of spherical curvature.

This is achieved by the fact that the frames are rigidly connected to the shields, and the fastening screws are locked in between the ends of the stand and the frames.

FIG. 1 shows a large sliding formwork, front view; in fig. 2 - the same, side view; in fig. 3 - the same in terms of; on fi-g. 4 - Structures of aluminum.

Sliding formwork for concreting (The linear and curvilinear walls of a constant curvature radius of the curvature includes a frame / consisting of two carriages 2 with individual traversing drives 3 and self-adjusting wheels 4, followed by the train, 3, I, I, I have to change the 22), I, I, I am going to I, I, I am going to I, I am going to I, I, I, I) I am going to I am going to I — I) I am I going to I am I going to I — I)) I have I’d moved I to I am I going to I have I’d going to I) I have I left my hands I to I to move I to myself, I am using IHTs, I to I to I have I left my hands and I, I, I, I am going to I) I am going to I to I, I have I left my hands I, I, I, I am going to I am using I am I am my The bases of which are attached to the trolley: KA1M 2 by bolted joints. In the central cavity of each column 6, plumb lines 7 are arranged for the correct exhibition of columns.

the parts of the whole column are bolted to the vertical sheets of the crosshead 8, on which lift drive 9 is mounted with bypass blocks W. The ends of the drive cables for lifting are fastened using four tension bolts to the two 6 bars sliding along the columns // //. Each slidable beam is equipped with two catchers 12, preventing it from falling when the cable is cut.

Rigid sliding beams U carry the formwork boards 13 from the working bridge (Mi and serve to fix the boards in a straight line or a spark, in the open position, and also to give the boards the rigidity necessary for operation. The feature of the design of formwork boards is M) that rigid rammes 14 are welded to the back side of them in equal lengths of length, nuts 15 and 16, respectively, with right and left threads, connected between the outer screws, are hinged to the rear posts of which, respectively.

The curvature of the shields is as follows.

If the screws are rotated in one direction, the back pillars of the frames come together, and the shield bulges; when the fastening screws are rotated in the opposite direction, the rear pillars of the frames are consumed and the working surface of the panel 01 deck | KI becomes new Wo | Bent. It is advisable to twist the shields and immediately after the installation of the alubki over the ridges or poppies attached to the fittings of the reservoir under construction. After sparking the BbiCTaiBKH shields, their raltki boards are attached to the top and the bottom of the sliding ball itself, which provides the necessary rigidity of the boards, then the wooden working platforms are laid on the upper belt. LORKI 18 are installed on the working sub-lands in the front section during the concreting process to receive concrete. It is most convenient to install the control panel using formwork on the working platforms on the outside of the concrete tank directly at the column closest to the stairs} 9.

The drive of the cart is equipped with a gripping device, which ensures optimum application of gravity, i.e., tangential to the curvature of the rail, bent according to the diameter of the reservoir under construction. The trolley travel drive is equipped with a device for smoothly adjusting the speed of the sialub travel and in the range from 0 to 18 m / h.

The design of rolling olors for the purpose of reducing the friction of the flanges of the traveling asoles on the rails provides for the possibility of rotating the axle 20 of the wheels, using the IOI on the segment supports 2 in horizontal silos. It is advisable to use sliding slides for concreted smooth concrete and reinforced concrete rectilinear and curvilinear stellar curvature of less than 10 cm, as well as with varying height and inclination. The walls are concreted in a row on the boards sliding in a horizontal direction, the concrete casting of the next track starts after the end of concreting of the previous one.

In addition, the formwork can be used for concreting the walls of tanks in a spiral, i.e., for continuous concreting of structures in a circle moving around along with the simultaneous lifting of the shields.

The peculiarity of TaiKoro concreting method is that the raviomer-continuous lifting of the boards for one revolution of the formwork should correspond to the height of the concrete layer 5. To this end, one of the traveling wheels of the cart is equipped with a lever for activating the lift drive for a time, depending on the setting of the time relay. The duration of the activation of the lifting drive depends on the diameter of the structure to be concreted and is determined by calculation.

After installation of the formwork and the exhibition of boards, the concreting of the first Rus begins. A hard concrete with a draft of 1-25 cm is used, its compaction is carried out with deep vibrators. The speed of movement of the pool depends on the time required to maintain the concrete in the boards, and on the air temperature and the length of the shielding itself.

The TaiK formwork shields move continuously, and concreting is carried out continuously. Upon exiting the boards, the concrete rus is affected by its own

5 weights and is loaded with the concrete of the next floor after the formwork returns to its original position after a few hours. This npolie enough that the concrete of the lower rus with proper care scored the necessary

0 durability and it was designed for: we are following the next light brown.

When using the formwork for the construction of the wall, it should be disassembled in two enlarged parts and moved to a prepared rail track using a crane.

Subject invention

Sliding formwork for concreting 0 linear and curvilinear walls of constant curvature radius, including a frame with shield frames with racks and SCALE screws, characterized in that, in order to ensure the construction of walls of a spherical curve 3, the frames are rigidly connected to shields, and the fastening screws for creiles between the ends of the racks.
