Abstract

The invention relates to a multipurpose reinforced concrete prefabricated columnless column system consisting of supporting columns (1,7) and ceiling panels (2) interconnected by means of articulated joints (3), which is detachable. The hinged joints (3) consist of anchor plates (4) and bearing plates (5) and are fitted with mounting elements (6). The anchor plates (4) are part of the support column (1, 7) and the bearing plates (5) are located in the corners of the ceiling panels (2).

Description

The invention relates to a prefabricated reinforced concrete non-coated column building system for multi-storey buildings. Its characteristic element is demountable joints of columns and large-size reinforced concrete ceiling panels, whose significant feature is the possibility of dismantling the system and re-assembling the system parts at another location and in another functional arrangement.

BACKGROUND OF THE INVENTION

Currently, there are several ways to solve demountable prefabricated reinforced concrete non-coating systems such as MXB-5, CD-20, SMT, Bestcon 30 or Moducon 2000. All are based on a combination of ceiling slabs, columns and walls. The ceiling panels are formed as cassette ribs, respectively. bidirectionally prestressed. The axial spacing of the columns is 3.6 to 3.9 x 5.4 to 7.5 m, the plate thickness is 200 to 400 mm, the dimensions of the square columns are 200 x 200 to 300 x 300 mm. The columns always have a height of only one storey, which does not allow eg a simple combination of floors of different heights and requires complicated bracing on each floor. Ceiling panels are usually terminated in the corner sections on the upper head of the columns. The contact between the ceiling slabs and the columns is carried out by means of pins, sometimes threaded, protruding from the column heads. In the corners of the ceiling slabs there are openings for the passage of these mandrels through the ceiling panel. In some cases, the joint holes in the ceiling slab are filled with low shrinkage mortar, making it difficult to dismantle the system.

Furthermore, there are a number of patents containing partial solutions of non-sheathed column systems, but not of demountable systems. Examples are the Ukrainian utility models UA 45790 (U) and UA 45788 (U) published November 25, 2009, the utility model UA 51630 (U) published July 26, 2010 or the Russian patent RU 2591994 (Cl) published July 20, 2009 2016 dealing similarly with preparations for attaching non-coated ceiling slabs to columns by means of welded joints, international patent application WO 2017078567 (AI) published 11.5. 2017 dealing with a connection between a non-coated ceiling slab and a column without heads, or Japanese patent application JPH 1096263 (A) published April 14, 1998 and US patent document US 5809712 (A) published September 22, 1998 concerning the attachment of apertured ceiling panels in the corners of steel darkness emerging from the head of the columns, subsequently filled with cement mortar. A similar solution is dealt with in Chinese patent CN 104947803 (A) published September 30, 2015. Another example is US patent document US 3354593 (A) published Nov. 28, 1967, respectively. Korean Patent Documents KR 101318284 (Bl) published June 25, 2013 and KR 101135881 (Bl) published October 19, 2011 dealing similarly by joining a ceiling slab through openings in its center to steel darkness emerging from the top of columns, subsequently filled with cement mortar.

In particular, these patents and applications do not address issues related to the dismantling of non-coating reinforced concrete prefabricated support systems, which would allow the system components to be reassembled elsewhere and in a different functional configuration.

SUMMARY OF THE INVENTION

These disadvantages are for the most part solved by a prefabricated reinforced concrete non-coated column building system with hinged joints according to the invention, which consists of prefabricated reinforced concrete columns and large-dimension reinforced concrete ceiling panels. Prefabricated columns of n-angular or circular cross-section are in the upper head

A3 201 with built-in steel fasteners to which are attached steel fitting elements, on which corners of large-size ceiling panels with built-in steel fitting elements are laid in the corners. The ceiling panels may be square, e.g. 3.6 m x 3.6 m, rectangular 2.4 to 3.6 m x 5.4 to 9.6 m, respectively. generally n-angled, with an edge length of 2.4 to 4.8 m, and may be solid or solid. ribbed and cassette, prestressed, event. not prestressed.

Dry mounting, resp. the dismantling and re-assembly of the ceiling panels with corners in the corners on the columns with built-in and additionally inserted steel profiles allow for quick and easy assembly and disassembly of the reinforced concrete structure. The demountable joints of columns and large-size ceiling slabs are designed on the principle of universal connection of the beam and the column, according to the Czech patent No. 305028 or 305454. The demountable contact consists of anchor plates placed in the column and metal storage plates placed in the corners of Fixing elements attached to anchor plates in columns. The anchor plates are built into the side walls of the vertical reinforced concrete column by means of anchor reinforcement and the metal support plates are built into the corners of reinforced concrete ceiling panels by means of anchor reinforcement.

The contact of the columns is designed as a contact, in which the upper column is placed directly on the head of the lower column, without interruption by the ceiling elements. Column contact is designed as articulated or rigid on the principle of connection of lower and higher floor columns with the possibility of eliminating wet processes, welding and screwing, with the possibility of its disassembly and reassembly at another location, according to Czech Patent No. 305679. from one protruding metal rod from the head of a lower stage column threaded and with a fitting, rectifying nut, on which a higher floor column equipped with a built-in metal plate with at least one hole is provided, provided with a plastic sleeve extending up to the cross section of the higher floor column or through an opening and a mounting pocket at the foot of the upper floor column to accommodate the coupling nut. The spatial stiffness of the demountable reinforced concrete prefabricated columnless column system is provided by embedded reinforcing elements - diaphragms, diagonals, etc. - connecting opposite columns in two mutually perpendicular planes, eg according to the Czech patent application PV 2013-848.
