Description

The invention relates to constructions made up of prefabricated slabs of thin-walled concrete with a new vertical solution. contacts in which monolithic occurs. The structure has _about I use for example in the construction of storage tanks cells SYP · sneeze wt. These are mainly low- and medium-volume grain containers for agriculture.

BACKGROUND OF THE INVENTION

Such containers and similar objects are currently built from metal elements or are cast from monolithic concrete into sliding formwork. Metal containers have a high specific consumption of steel and are therefore economically disadvantageous. Concrete monolithic containers have a high material consumption, which is also economically disadvantageous. Monolithic concrete walls are several times thicker than in prefabricated constructions. For sliding formwork, complex and costly equipment is required, which must be individually installed at each construction site. It is therefore an attempt to replace these costly structures with an economically and materially advantageous system.

The advantageous solution seems to be the application of prefabricated structures of z-elements made of thin-walled concrete, i.e. elements or elements. boards with wall thickness up to 50 mm. The wider application of this material to these purposes has hitherto been mainly hindered by the fact that the question of the optimal shape and cross-section of the slabs, and in particular the question of wall plate joints, in particular vertical joints, has not been reliably solved.

If thin-walled concrete elements have been used so far in the construction of grain containers or similar objects, the tanks were relatively low, the base plates had a simple wavy cross-section and were assembled in the vertical position of the waves into circular cells by downloading monolithic circumferential concrete rims. This type proved to be unsatisfactory. The system of circumferential concrete rim is difficult to solve under prefabrication conditions.

2 of the invention

The prefabricated structures of the present invention consist of a set of concrete elements. The basic element is concrete thin-walled, horizontally profiled plates of angled cross-section, which create walls of structures. When assembling these plates, the profiling is oriented horizontally, at the upper and lower edges (parallel to the horizontal profiling) the plate is provided with a groove and a cutting edge for mutual alignment and forming horizontal contacts.

In the spatial construction, these horizontally profiled slabs are connected at the point of contact of their faces by pillars which are formed of at least 3, preferably 4, vertical straight slabs of thin-walled concrete. At least 2 of these plates have a broken groove on the surface corresponding to the cross-section of the horizontally profiled plate. In this groove when connected horizontally profile, the plate with its face snaps. The groove is provided with openings through which the steel reinforcement of horizontally profiled plates is threaded and subsequently fixed. The columns are filled with vertical reinforcement and concrete.

The fractured cross-section of horizontally profiled plates most often has the shape of a trough with a flat bottom and sloping sides with a reinforcing edge that is parallel to the bottom. The axial height of the cross-section is preferably 160 mm. The selected cross-section has high pressure resistance of the bulk material and eliminates the deposition of this material inside the containers. The vertical straight slabs are also made of thin-walled concrete. They preferably have a thickness of 50 mm and a width of up to 400 mm. Material other than concrete is unsuitable for these boards.

The material from which the basic structural elements are made is thin-walled concrete. It is common iron concrete with a wall thickness of up to 50 µm. The thickness of the most commonly used elements in the structures of the present invention is 20-30 mm. The material generally contains an insert of a woven mesh and the longitudinal reinforcement of the individual elements P 6 AP 12. The longitudinal steel reinforcement strength insure a horizontal profile, board and its protruding ends of the plates allow anchoring of the ^J-cut in vertical columns and also ensures cohesion of the structure. The vertical straight plates also have their reinforcement, which does not protrude from them.

Additional vertical reinforcement is inserted into the posts formed by these plates, which is poured with concrete and increases the strength of the posts.

Ί .j

The actual joining of a set of profiled slabs of thin-walled concrete by means of columns made of vertical straight slabs is performed as follows *.

The horizontal * profile reinforcement of the wall plates with angled cross-section is threaded through the hole in the vertical flat plate resp. its groove and secure with the plate. The panels joined in this way - the wall panels - are assembled in the shape of a post and connected to the bolt. The vertical reinforcement is placed on the column and the concrete mixture is poured. The outer and corner posts are completed by means of straight plates, which can be without a broken groove. The wall elements are pulled together at each height. After assembling the two or three stacking heights, the concrete is poured into each post.

The horizontally profiled plates can advantageously be pre-bonded with the respective vertical plates to form prefabricated elements which, in the actual construction, merely fold together to form corner posts and are then consolidated as described above.

The basis of the assembled structures of thin-walled concrete according to the invention is based on a new technique of joining wall plates - making vertical joints. These newly designed joints have, as has been proven, satisfactory static strength ensured by interconnecting the panels and absorbing vertical and horizontal forces from the load, self weight and wind. The monolithing that occurs when the joints are cast by pouring the columns with concrete mixes is achieved without any formwork or aids or auxiliary elements, which greatly simplifies the entire construction process. The individual elements are assembled dry and then only the connecting nodes of the system - columns are poured in the concrete.

The application of these constructions makes it possible to use prefabricated elements made of thin-walled concrete in the construction of various objects, especially storage tanks and silos for the storage of some agricultural products, especially grains such as grain and the like. However, there are other options, such as fencing construction and more.

Overview of the drawings

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view of a horizontally profiled wall plate; FIG. 2 is a plan view of a joint between wall and vertical plates;

Fig. 3 is a view of the column. 4 shows the application of the structure - a thin-walled concrete container in vertical section.

DETAILED DESCRIPTION OF THE INVENTION

The assembled structure of thin-walled concrete consists, according to FIG. 1, of horizontally profiled plates of angled cross-section 1 with a groove 2 and a blade 3 on the longitudinal edges for mutual fit.

The plates are joined together by pillars made of vertical straight plates 4 at the point of contact between their faces. Each plate 4 forms one column according to FIGS. 2 and 3. Each plate 4 has a broken groove 5 on its outer surface corresponding to the cross-section of plate 1. The groove plate 1 engages with its face. In these grooves further, according to FIG. 3, there are openings 6 through which the anchoring reinforcement 7 of the horizontally profiled plates 1 passes. A securing plate 8 with a cut-through hole is threaded onto the reinforcement 7, which holds the plates 1 and 4 together during assembly. The ends of the reinforcement 7 are then bent at right angles.

The horizontally profiled plates 1 connected to the vertical plate 4 are then stacked in a perpendicular direction to form a vertical column according to FIG. 2 which is firmly connected by bolts 9. The vertical reinforcement 10 is inserted into the columns so formed and the entire interior of the column is covered with liquid. concrete. The container shown in Fig. 4 is composed of plates 1 and plates 4 forming columns. The panels thus assembled form stack cells resting on beams 11 supported by the pillars 12. The bottom of the cells is formed by hoppers 13. The cells are covered by the ceiling 14 and the entire stack by the roof 15. The stacks can form an assembly composed of any number of these cells.

Industrial applicability

The prefabricated structures of the present invention are useful for thin-walled concrete objects, for example, for the construction of small and medium grain capacity agricultural containers.
