Description

The utility model relates to the field of construction, namely, devices for the construction of domed spherical structures and can be used as a removable removable formwork for the construction of domed spherical shells, buildings and structures for various purposes. [E04G 11/04, E04G 11/34]

The prior art method of construction of curvilinear structures [WO9528538 (A1), publ. 10.26.1995], in which the anchor mast is used, the arm of the anchor having a vertically and horizontally rotating arm ending in a guide for the reinforcing bar (reinforcement), and the corresponding fastening equipment. The garter guide is aligned with a part of the vertical reinforcement, and a separate piece of horizontal reinforcement is placed next to and, as a rule, vertical reinforcement fixed to it. The linking guide is then moved to engage the adjacent portion of the vertical reinforcement, and the horizontal portion is bent inward to be fixed thereto. As the armature arm moves around the mast and gradually rises, additional vertical and horizontal parts of the reinforcement can be brought into an adjacent position and secured, thus creating a non-planar mesh of reinforcement and weaving of other required reinforcement (crossing patterns). An impermeable layer is placed above the mesh, and a reinforcing material is applied to form a rigid shell.

The disadvantage of the analogue is the complexity of the equipment and the complexity of the process.

Also known from the prior art DEVICE FOR CONSTRUCTION OF CONCRETE BUILDINGS [US4372733 (A), publ. 02/08/1983], containing a removable form, forming a surface of revolution, having a Central axis and having a shape that defines the desired configuration of the concrete structure; support column mounted on the central axis; a unit including a concrete batcher and local concrete storage means for supplying concrete to the batcher; and means comprising a movable frame for mounting said concrete dispenser to move around the periphery around said mold and gradually from the bottom to the top of said mold for applying concrete in strips substantially over the entire outer surface of said mold to form a thick concrete wall on the outer surface said mold, said fixing means includes means for supporting said assembly substantially independent of the concrete wall being formed.

The disadvantage of the analogue is the complexity of the equipment and the complexity of the preparatory work.

The closest in technical essence is the FORM FORMWORK AND THE METHOD FOR CONSTRUCTION OF THE FAMILY OF DOME-SHAPED SHELL CONSTRUCTIONS [WO2016156915 (A1), publ. 10/06/2016], which proposed a method of constructing a dome by reusing the main segment, including: a) determining the shape of the dome; b) determining the structure and dimensions of the element of the basic structure of the dome, called the formwork, while the element of the basic structure represents a fraction for the formation of the structure of the dome when it is symmetrical and repeated; c) bending the formwork into the desired shape, while the desired shape is a symmetrical small base of the dome; d) the rotary formwork and the support of the rotary formwork through the support truss; d) installation of the formwork over the supporting structure; f) filling the filler into the formwork, the filled material solidifying within a predetermined period of time; g) repeat the steps from (a) to (e) near the initial location of the formwork, and the repetition continues until the formwork reaches the end position symmetrically opposite to the original position.

The main technical problem of the prototype is the complexity of the processes and the complexity of the equipment for moving and securing the formwork section in intermediate vertical positions due to the weight and bulkiness of the section in the form of a full fraction of the hemispherical shell structure necessary to ensure stability and strength when applying dome material to concrete formwork (concrete, cement concrete ...).

The objective of the utility model is to eliminate the disadvantages of the prototype.

The technical result of the claimed utility model is to reduce the complexity and complexity of manufacturing a domed building.

The specified technical result is achieved in a device for erecting a monolithic dome building, which is a section of a movable formwork in the form of a fraction for the formation of the dome structure with its symmetrical and repetitive application, characterized in that the formwork section is held through the hinges by lower and the upper rods connected to the support stand, in the upper part of which a ring is attached to form a circular opening in the domed building, while the support stand through brackets is mounted vertically at the axial point of the annular foundation of the walls of the domed building with braces to the floor screed through the eyes, and in the lower part of the section formwork, for its movement around the support post to a new position, a wheel support with a wheel is installed.

In particular, the formwork section is made in the form of a spatial truss sheathed from the working side by sheet material curved along its curvature.

In particular, the lower and upper rods are adjustable in length with the help of lanyards.

In particular, the connection of the formwork section by lower and upper rods with the support column is made through loose fit bushings, the lower of which rests on the pin, and the upper on the brackets.

In particular, the support column is fixed through brackets to the eyes in the floor screed with guy rods by means of articulated joints.

In particular, the ring for forming the circular opening of the domed building contains a fixed shell and its removable fastening to the support column, which is secured with a bolt to the clamp, and to the shell by means of self-tapping screws.

In particular, the wheel is fixed with a bolt assembly in the eyes.

In particular, the wheel supports are made with the possibility of the wheel taking the weight of the formwork section in the transport position, for example, by means of a lifting insert installed between the wheel support and the lower part of the spatial truss to form a transport gap when rolling the formwork section to the next position.

Implementation of a utility model.

The claimed device for the erection of a monolithic dome building consists of a support rack 1 with a ring 2 attached to its upper part to form a circular opening of the dome building, containing a casing 3 and its removable mount 4 to the support rack 1, which is secured with a clamp 5 by a bolt connection 6, and to the casing 3 with self-tapping screws 7, while the support stand 1 is located vertically at the axial point of the annular foundation 8 of the walls 9 of the dome building and is fastened with guy rods 10 through swivel joints 11 through the eyes 12 in the st the floor yoke 13 and the brackets 14 for holding the formwork section 15, which is a spatial truss 16, sheathed from the working side by sheet material 17 curved along its curvature, the upper link 18 and lower rods 19, adjustable by means of lanyards 20 and connected, by means of hinge joints 11, at one end to the formwork section 15, the other to the support column 1 through the upper sleeve 21 and the lower sleeve 22 freely supported on it, resting on the pin 23, sliding the upper sleeve 21 is limited by brackets 14, and to move around the circumference around the support column 1, in the lower part of the formwork section 15, by means of articulated joints 11, a wheel support 24 is installed with a wheel 27 fixed with a bolt assembly 25 in the eyes 26, the weight of the formwork section 15 in its transport position through the lifting insert 28, thereby forming a transport gap 29 between the floor screed 13 and the lower edge of the formwork section 15.

A device for the construction of a monolithic dome building is used as follows.

An annular foundation 8 is made under the walls 9 of the domed building under construction, and inside the foundation, a screed 13 is poured into which the eyes 12 are installed, where the hinge joints 11 of the guy wires 10 are fixed.

Next, on the screed 13, the support column 1 is horizontally placed, the brackets 14 are welded to it, into which the swivels 11 for fastening the guy wires 10 are installed, the upper sleeve 21 with the swivel joint 11 for attachment is mounted on the support rack 1 the upper link 18, the lower sleeve 22 with a swivel joint 11 for attaching the lower links 19, the pin 23, and also the ring 4 for forming a circular opening of the dome building, comprising a fixed shell 5 and its removable mount 6 to the support column 1, which is fixed with a clamp 2 with a bolted connection 3, and to the side 5 with self-tapping screws 7.

After that, the support post 1 is lifted with all the assemblies mounted on it and fixed in a vertical position in the center of the screed 13 using guy wires 10 and swivel joints 11. The final installation of the support post 1 in a strictly vertical position is carried out using 10 turnbuckles mounted on guy wires (not shown).

Next, two lower rods 19 and an upper link 18 are connected to the support column 1 through articulated joints 11. Then, on the screed 13, the formwork section 15 is assembled with the sheathing of the working surface of the spatial truss 16 with sheet material 17, as well as with the wheel supports 24, lift it and fixed in the design position by attaching the lower rods 19 and the upper link 18 to it with the help of swivel joints 11, while adjusting the exact location of the formwork section 15 in the design position using lanyards 20. The formwork section 15 is brought into working position and is ready to be applied to it concrete. When this transport gap 29 (Fig. 3) is absent, the formwork section 15 is based on an annular foundation 8 (Fig. 4).

After applying concrete mixture to the working surface, for example by spraying or torqueting, and hardening it, the formwork section 15 is redressed, for which the upper link 18 is first shortened with the help of a lanyard 20, then both lower links 19 are shortened one after the other, then the formwork sections 15 are given the transport position, why, using any lever (not shown), both edges of the formwork section 15 are raised alternately in the area of the wheel bearings 24 by the amount of transport clearance 29 and the lifting inserts 28 are installed alternately between the section th formwork 15 and wheel bearings 24. The weight of the formwork section 15 is perceived by the wheel 27 fixed in the eyes 26 by means of a bolt assembly 25 to the wheel support 24. Next, the formwork section 15 is rolled over to a new position and brought to its working position, for which it is removed from using any lever (not shown), the lifting inserts 28. The cycles of bringing the formwork section 15 into working and transport positions are repeated until the dome building is fully erected.

As a result of the trial operation of the device for erecting a monolithic dome building, a significant reduction in labor costs and the complexity of erecting the dome building was observed due to the possibility of horizontal movement of the formwork section to the next position by rolling around a vertical rack using wheel supports with a wheel. At the same time, the dead weight of the formwork section has a positive effect for imparting stability and precise fastening in the working position, which eliminates the need for complex mechanisms, energy supply and significant labor costs for changing the position, as well as fixing and accurate positioning of the formwork section in the working position.

Thus, the effect obtained by simplifying the design of the mechanisms for moving and securing the formwork section in the working position, significantly reduced the complexity and complexity of manufacturing the domed building.
