A SET OF PREFABRICATED CONSTRUCTION ELEMENTS

The subject of the invention is a set of prefabricated building elements that can be used in housing, industrial and engineering construction.

It is known from the Polish patent description No. 93508, a set of building elements consisting of a single (double and one and a half times) basic element, one (both) of the shorter walls of which has a shelf formed from the center of the element, parallel to the arm, forming a catch for the arm. arm of another element. From the Polish patent description No. 121186, a set of prefabricated building elements is known, which consists of a floor block, a wall block and a jamb block. These kits enable the use, in the design and construction, of walls of residential buildings, or walls filling structures.

The aim of the invention was to develop a universal set of building elements, enabling effective use in residential and industrial construction, for the construction of fences and elements of small architecture, for making facades, insulation and insulation of walls, construction of continuous footings and pillars / etc. It was achieved according to the invention, in in that the set of prefabricated building elements consists of an outer, middle and corner block.

The outer element has at least two trapezoidal projections with longitudinal openings on one of the side walls. The middle member has the same trapezoidal protrusions with longitudinal holes: on both side walls, and the corner member has a trapezoidal protrusion with a longitudinal hole on one of the inner corner walls. The thickness of the trapezoidal protrusions is approximately equal to the thickness of the walls of the elements, and the diameter of the longitudinal holes is in the range of 1/2 to -3 / 4 of the thickness of the walls. The ratio of wall thickness (excluding protrusions) to the height and length of the outer and middle members is 1: 4: B, and the ratio of thickness to length of the legs of the corner member is 1: 4.

Elements of the set according to the invention can be made of concrete, expanded clay or other binders, e.g. alkaline or dust from heat and power plants. The set of elements according to the invention can be used for any construction in residential, industrial and engineering construction, in particular for:

- multi-layer walls of residential and industrial buildings,

- walls filling steel or frame structures;

- lost formwork of reinforced concrete structures,

- smooth or grooved fencing elements,.

- foundation footings and columns,

- façade elements, insulating external walls or insulating against noise, etc.,

- small architecture structures.

An exemplary embodiment of the invention is illustrated in axonometric views in the drawing, in which fig. 1 shows the outer element, fig. 2 - central element, fig. 3 - corner element, fig. 4 - embodiment of a multi-layer wall made of kit elements, fig. - an example of a fence, thermal insulation wall, etc., and Fig. 6 - an example of using the elements for the construction of a pole.

The outer element 1, on one of the side walls 4, has two trapezoidal projections 5 with longitudinal holes 6. The central element 2 has trapezoidal projections 5 with longitudinal holes 6 on both side walls 7 and 8, and the corner element 3 has a projection 5 with an opening 6 on one of the internal corner walls 5. An example of the use of elements according to the invention in the construction of multi-layer walls is shown in Fig. 4. External elements 1 and middle elements 2 are used. In the longitudinal openings 6 of the projections 5 there are sections 10 of reinforcing bars, which creates the possibility of managing production waste. The construction of only external elements 1 - fig. 5 - can be used as fences, wall insulation, lost formwork in civil engineering, etc. From the corner elements 3, columns can be constructed as shown in fig. 6.

Claims (2)
