The present invention relates to the field of construction, in particular to methods of erecting floors of buildings and structures.

The known method of installation of floors of buildings for industrial and mounting system (IMS) (see, for example, an article by Koprivica B. "Application frame system IC for the construction of residential and public buildings". - W-l Housing. - 1984, No.1, p.30-32). The known method includes the placement of the floor slab at the time of mounting the tables and counters, monolithic high strength cement mortar all contact and interplate seams, extract it to acquire the necessary (vintage) strength. Then through the holes in the columns and all of the longitudinal and transverse axes of the building between the plates is rough pre-tensioned reinforcement, followed by pulling her in two orthogonal directions and concreting of axial seams with a tense high-strength reinforcement. Due to the compression plates of high-strength steel ropes made the connection concrete slabs in floors discs. With the outer faces of the columns ropes aneroussa collet clamps that after construction of the concrete slab.

The use of the known method of stress reinforcement on all longitudinal and transverse axes of the building allows you to create a system that is the input of the load at fracture of its separate elements. The main feature of the system IC is that in the process of assembling the main load-carrying elements of the framework (pre-tensioned reinforcement, anchor nodes, concrete slabs and columns in the zone of their contact) have a voltage in excess of performance.

However, in the known method of installation of floors maximum disk size of the slab is limited to a single cell columns, and the column selected in the range of 6.0-7.2 m, which significantly narrows the range of space-planning decisions and, therefore, reduces the effectiveness of this method.

Closest to the proposed technical essence is a way of mounting disks floors of buildings and structures, including the installation of inventory staging, placing them in a project position floor slabs with a gap between the plates, installation clearances to the entire width and length of the building pre-tensioned reinforcement, and piling into the gaps and form placed around the perimeter of the building, concrete (see, for example, patent RF №1776734, CL E04B 1/18, 1989). After the poured concrete laid armature with the formation of precast-monolithic beams in 2 perpendicular directions to produce tension reinforcement and anchoring with subsequent concreting beams at full height.

The known method of mounting simplifies installation blocked by the th, to increase the reliability of the frame of the building due to the prestressed reinforcement beams, as well as create a hard nodes of the pair of columns with the HDD in the ceiling.

However, the known method of mounting ceiling allows you to send pre-tension reinforcement mainly on concrete beams and thereby eliminate the significant value of the contact stresses in the joints between the columns and floor slabs in tension reinforcement, which can lead to the bevel plates, damage to columns, etc. however, the compression beams only partially transmitted to the floor slab, and in General to disk floors, which greatly reduces the carrying capacity of the disks overlap. In addition, the known method of mounting drives very time-consuming in implementation: it is difficult enough in construction conditions to place pre-tensioned reinforcement is one of the main elements forming disks floors according to the calculated plot of bending moments.

The purpose of the invention is the acceleration of works on installation of overlap, the increase in the operating characteristics of the disks overlap.

This objective is achieved in that in the method of installation of the ceilings of buildings and structures, including the formation of the supporting columns disks slabs of concrete slabs with Groovy side faces between Riga is s, connecting the load-bearing columns, and in the cavities of the crossbars put steel rope; slabs made with cut-outs for reinforcing ropes, mounted on the mounting tables are also made with similar notches, and the notches in the plates and the mounting table is combined with each other, and then enters the reinforcing ropes in the notches concrete slabs and produce tension of the ropes on the plate located between the beams, and in the cavities of the beams to the required values of the tensioning device, generating package disk overlaps with the subsequent concreting of the grooves and crevices of each package and cavities crossbars rapid hardening cement-sandy solution, after then remove the mounting tables.

The essence of the proposed technical solution is as follows.

Concrete slabs prefabricated according to the proposed technical solution is collected on the final frame of the building between the crossbars mounted on the supporting columns, preferably from troublethe, in packages of disks floors containing from 3-4 10-12 plates, depending on the size of a single cell and the span. Accommodation in the hollows of the hollow core concrete slabs of high-strength reinforcing ropes with their subsequent tensioning and anchoring in bars, is what's at the ends formed by the disk ceilings, ensures this stress state of concrete part of the disk, in which all stresses in the overlap process operation from permanent and temporary loads, temperature, etc. are concrete drive, working a full cross-section, unlike the prototype, in which the pre-tension of the armature is transmitted primarily on concrete beams and only a small part of the concrete floor slabs, significantly reduce the carrying capacity of the entire disk overlap. According to the proposed technical solution in the work of concrete building structures involved and the stretched area of the concrete cross-section, which allows you to get a design that has no cracks. The accommodation is pre-tensioned reinforcement in the beams increases the bonding strength of the concrete slabs in the disc overlap, and also provides for the creation of hard knots pair of columns with the disk, which even more increases the strength and reliability of disk floors in General.

The proposed method of installation of the floors is as follows.

On the Foundation supports mounted trubobetonnykh columns, connecting them to each other with steel beams - beams I-beam, box, etc. section. Between the crossbars establish temporary mounting tables, on which is placed the hollow core slabs. The outer surface of the mounting table and the lower surface plates are manufactured with grooves for placement of reinforcing ropes. When installing the plates on the mounting tables grooves combine with each other to form a through channel through which then stretch pre-tensioned reinforcement, produce tension and santriani in the crossbars. At the same time in the cavities of the steel girders are placed similarly to the prototype high-strength reinforcing rope and also expose them to tension with subsequent anchoring at the surfaces trubobetonnykh columns, through holes in which miss reinforcing rope. After concreting cavities with ropes, placed in bars, and interplate seams and joints of plates overlaps with columns temporary mounting tables clean, and the notches in the bottom surface of the concrete slabs placed in them tight fittings are poured.

The proposed method of installation 1.3-1.5 times allows you to accelerate the construction of floors, to create long-span floor construction, perceiving almost any voltage caused by operational loads. Moreover, such structures have a high cracking: cracks that occur in them from accidental overloads, completely disappear after unloading. The method provides a free, flexible packaging is th layout of the premises, helps reduce operating costs through increased operational reliability of the ceiling.

The method of installation of the ceilings of buildings and structures, including the formation of the supporting columns disks slabs of concrete slabs with Groovy side faces, characterized in that between the crossbars connecting the load-bearing columns, and in the cavities of the crossbars put steel rope; slabs made with cut-outs for reinforcing ropes, mounted on the mounting tables are also made with similar notches, and the notches in the plates and the mounting table is combined with each other, and then enters the reinforcing ropes in the notches concrete slabs and produce tension of the ropes on the plate located between the beams, and in the cavities of the crossbars to the required values of the tensioning device, generating package disk overlaps with the subsequent concreting of the grooves and crevices of each package and cavities crossbars rapid hardening cement-sandy solution, then clean the mounting tables.

SUBSTANCE: entire process of panel assembly from steel galvanised shapes takes place in building ways comprising a bed, mechanisation elements, electric equipment and two stands: a stationary and a mobile ones, along which carriages may move, setting various angles of inclination and height of the assembled panel relative to the horizontal plane, and the mobile stand itself may move along the building ways along the horizontal line, providing for the preset panel length. Carriages and the movable stand are controlled automatically from a control station. Assembly of panels in the building ways is started from installation of transverse shapes according to basic openings onto fixators of carriages of the stationary and movable stands and pulling of the shapes to the plates of the carriage shaft by rotating magnet handles. Then the movable stand is moved along the building ways along linear guides, keeping the length of the assembled panel. Then longitudinal profiles are installed between transverse ones and fastened at one side. Afterwards the carriages with a panel frame fixed on them are raised into the upper position and are rotated by 180. Then the carriages with the panel frame are lowered to the height convenient for assembly. Then shapes are fastened at the opposite side to form a stiff frame of the panel, and lining is installed on this side. Afterwards the frame with the lining is raised into the upper position, rotated by 180 and lowered down, the insulant is laid, and the lining is installed on the second side of the panel, the finished panel is removed from the building ways, with preliminary disconnection of magnets and removal of carriage fixators.

EFFECT: building ways design does not block up the working space around the frame of the assembled panel, leaves free access and approach to areas of assembly and makes it possible to perform assembly works at different levels without reinstallation of the assembled panel.
