Description

The invention is an enhancement auth.St. No. 916685 and can be used for the construction of temporary residential and auxiliary buildings of small number of storeys.

The aim of the invention is to reduce metal consumption and increase operational reliability.

FIG. 1 shows the modular assembly section / upper overlap - on insulation, the bottom - on the transverse beam /, cross section; in FIG. 2, section A-A in FIG. one; in fig. 3 shows the node I in FIG. one.

The modular section of the module contains upper and lower overlaps, made in the form of a three-layer frame insulated panel, formed by a rigid frame of bent profiles, transverse bars 1, supported by short-racks 2, upper casing 3 of nailing plates, lower casing 4 - flooring of trough-shaped section, connected with short posts by 2 self-tapping screws 5, and along the contour with 6 bent profiles of a rigid frame with bent shelves by means of self-tapping screws 7, foam insulation 8, located between the bent and rigid frame profiles and linings 3 and 4 pillars 9, a junction of the upper and lower floors at the corners, and wall panels 10. The ends of the transverse bars 1 are located between the support 11 and the bent profile 6 bent profile shelves with an end face facing into the outer a vertical wall 12 of the bent profile and attached to the bent shelf 6 of the bent profile with the help of the corners 13 with self-tapping screws 14. The vertical limb 15 of the bent profile of the lower overlap is included in the longitudinal groove 16 of the wall panel 10. On the inside the wall panel 10 is fixed at legs 17 connected to the transverse bars 1 and the wall panel 10 with self-tapping screws 18. The supports 9 are made of an angled curved profile with bends and flanges for mating with the vertical bends. 15 curved rigid frame profiles. In order to protect the foamed insulation 8 from moisture between the last and upper skin 3, for example, insulation 19 is laid out of plywood in the form of roofing material. Two bent shelves 6 cross curved profile can

match the adjacent contour of the lower skin 4.

The modular section of the module is manufactured on a production line in the following sequence.

The sheet bending equipment performs curved frame profiles, of which frames of floors are welded. In parallel, galvanized steel sheets with overlap and spot welding are used to fabricate the bottom casing 4 (trough-shaped flooring), which is then placed on the bend with the help of a magnetic cross bar on the 5th shelves of 6 bent profiles and fixed to the frame with self-tapping screws 7 and spot welding. Next to the transverse bars m 1 in the spike, fasten stand-short 2 and lay them together locally on the bottom casing 4. At the same time, the ends of the transverse bars 1 are turned into. the horizontal cavity of the curved profile of the frame, rest them on the bent shelf 2 of the curved profile, after which

The 25 short posts 2 are fastened to the bottom casing 4, and the transverse bars 1, using the corners 13, to the bent shelf 2 with self-tapping screws 14.

The overlap assembled in this way is moved to the molding position with the help of the crane-beam and placed on the POA DON which repeats the lower surface of the overlap. The shaping position is equipped with four supports equipped with electromagnets on which a rigid upper deck is placed — a magnetic press at the level of the top of the overlap. The current is turned on, the upper deck is pressed against the supports and the overlap, after which liquid insulation components, such as phenolic or Vilares, are foamed into the holes of the rigid frame and foamed and fill the closed space bounded by the internal faces of the rigid frame rigid profiles, the upper casing 3 of the nailing plates and the bottom casing 4. Thus, an overlap in the form of a three-layer heat-insulated panel with thermal properties is obtained, then it is attached to rigid frames t in welding corner posts 9, and wall panels 10, the roof and floor installation 55 are mounted to the ceilings of the assembly section by means of known methods.

The decrease in metal consumption is ensured by the fact that the bottom plating 4 is 35

completed in the form of flooring-trough-shaped section, which forms a membrane that works only for stretching; In addition, the transverse bars 1 and the bottom plating 4 work together on the principle of a truss beam. Due to the pinching of the ends of the transverse bars 1 in curved profiles of rigid frames and the reception of transverse bars m 1 of reverse thrust from the lower skin, the material consumption for the transverse bars 1 is reduced.

The operational reliability is enhanced by eliminating the instability of the floors. Filling the internal volume with foam foam insulation of bent rigid profiles, floor frames eliminates the need for periodic internal painting of the metal.

The assembly design is associated with low manual labor costs due to the use of a high-performance screwdriver when screwing in self-tapping screws (up to 600 screws per hour).
