Description

Technical field

The invention relates to connection modules for building structures in modular design of vertical and horizontal structures provided with connection elements. It is a prefabricated system with removable elements, with the possibility of changing their stiffness, and with the possibility of disassembling and reassembling elsewhere. This is a so-called “dry joint”, without grouting with concrete or without welding, allowing easy disassembly and relocation and reassembly.

BACKGROUND OF THE INVENTION

Similar systems are disclosed in numerous patents. For example, Japanese Patent Application JP 11256728 (A), published September 21, 1999, Bracket, joint and fixing method, by BHP STEEL JLA PTY LTD, JP. The bracket is formed by a web material provided with a contact portion of a planar wall mounting assembly and a base anchoring portion. The attachment part is attached to the wall frame and the base anchoring part is attached to the building element to the upper surface of the concrete slab. In this case it is only a detachable connection of the base anchoring part to the upper surface of the concrete slab.

Another example is Japanese Patent Specification JP 2003064766, published March 5, 2003, Precast concrete wall and its construction method, by NIPPON KAISER KK, JP.

The prefabricated concrete wall is made between the upper deck and the lower deck using a prefabricated concrete wall slab positioned therebetween. A tie rod extending from the upper surface of the lower deck is inserted into an insertion hole on the lower surface of the precast concrete wall plate, a tie rod extending from an elongated hole on the lower surface of the prefabricated upper floor is inserted into the insertion hole on the upper face of the precast concrete wall plate. around a portion housed in the elongated bolt hole. It is a relatively complicated construction, which is already outdated.

Another example is German Utility Model DE 20307595 (UJI) published on July 10, 2003, Method for joining concrete panels in a building with a threaded sleeve in one panel and a guide sleeve for a threaded fastener in an adjoining panel. threaded sleeve in one panel and guide sleeve for threaded clamp in the panel to be attached), applicant Veit Dennert KG Baustoffbetriebe, DE. It is a wall structure with at least two mutually rectangular wall elements in the form of prefabricated concrete parts and at least two screw elements between the wall elements, wherein the screw elements have a threaded sleeve firmly embedded in the wall element, a through hole arranged correctly to the threaded sleeve through a wall element, and a screw bolt engaging through the through-bore with the threaded sleeve. In addition, there is an insert which closes the mounting hole in the thermal insulation layer after assembly. The advantage is the joining of the wall elements by screw bolts, but the disadvantage is the disassembly of the wall elements, which is associated with the problematic removal of the inserted part from the mounting hole.

Another example is EP 1 405 957, published on April 7, 2004, Noccealed console joint, by Tartuntamarkkinointi OY, Finland (Fi). The recessed cantilever joint is used to connect vertical and horizontal frame elements in buildings. The cantilevered connection comprises a coupling adapter by means of which a connection can be made by joining the first and second coupling elements without any parts extending from the horizontal frame element. Said second coupling element comprises a gap which is open at its lower end and through which the bracket portion of the coupling adapter can be received. i.

to the second fastener. Again, it is a relatively complex construction, which is already outdated.

Another example is International Patent Application WO 2012/006 764 A1, published January 19, 2012, Connecting structure for embedded-type composite profile, by Ningbo Bangda Ind Co. Ltd., China (CN). The joining structure for the flush-type composite profile comprises a standing column and beams which are in the form of thin-walled columnar bodies formed by alternating support of elongate members. The upright column and the beams are vertically connected by a connected joint comprising a bottom plate and a yoke projection provided with a cavity in a vertical direction to the bottom plate. The yoke protrusion and the beams are connected by a sliding fit and the bottom plate and the side wall of the standing column are connected by a fastening element. This is a relatively advantageous construction solution, but the construction is again relatively complex and is already outdated.

Another example is the international patent application, WO 2012/149 905 A1 published 08.11.2012, Beam hanger, building 3framework structure and instalation, by Yang Dongzuo, CN. The beam hinge comprises an integral coupling insert or support joint, a hinge portion and a connecting portion. The frame structure of the building comprises at least two beam hinges, both ends of the beam being fastened by an integral coupling insert or a support joint. The beam is directly supported by the suspension part on which it is suspended. The assembly method comprises the following steps: inserting both ends of the beams into the beams of the beam, slidingly connecting the beam and the beams of the beam, suspending the beam's beam to the respective beam, adjusting the relative positions between the beam and the beams, and fastening the beams with the beams. It is an advanced design solution, allowing relatively easy assembly and disassembly, but containing different design elements from the design claimed.

SUMMARY OF THE INVENTION

These drawbacks are largely eliminated by the structural modules of the structures, in particular for joining the vertical reinforced concrete pillar and horizontal reinforced concrete beams, with the possibility of disassembling and reassembling elsewhere, according to the invention, which consists of connected anchor plates and bearing metal plates slid from above onto the mounting elements attached to the anchor plates.

In one embodiment, the anchor plates are embedded in the side walls of the vertical reinforced concrete column by its anchoring reinforcement from both sides, and the metal support plates are embedded in the faces of the reinforced concrete beams by means of the anchor reinforcement.

In another exemplary embodiment, the metal mounting elements are attached to the anchor plates by fastening screws.

Clarification of drawings

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be explained in more detail with reference to the drawing, in which: Fig. 1 shows a vertical pillar connection module with a horizontal die on one side and Fig. 2 shows a vertical pillar connection module with a horizontal die on both sides.

DETAILED DESCRIPTION OF THE INVENTION

Fig. 1 shows a connection module connecting a vertical reinforced concrete column S with a horizontal reinforced concrete beam P. The vertical reinforced concrete column S is provided on both sides with anchor plates 1, which are incorporated into it by means of anchor reinforcement. Further, there is shown one horizontal reinforced concrete die P into which a metal plate 4 is inserted by means of anchoring reinforcement, slid from above onto a molding element 2 (not shown) attached to the anchor plate 1, which is covered on this side by the slidable plate 4. not visible. The shaped fitting element 2 itself is shown on the other side of the vertical column S, where it is attached to the outside of the anchor plate 1, and is ready for sliding of a metal storage plate (not shown) and ready for sliding of a complementary shaped metal plate 4. to the shaped mounting element 2.

The mounting element 2 is in the shape of an inverted U and is provided with a recess for locating the metal support plate 4 provided with a recess for mounting on the mounting element 2, the mounting of the mounting element 2 preventing release of the die P from the S-column. if necessary.

In Fig. 2, unlike Fig. 1, two horizontal reinforced concrete beams P, with built-in metal support plates 4, are slid from above both sides to form fitting elements 2, fastened to anchoring plates 1 built into the vertical column S.

The connection module according to FIGS. 1 and 2 consists of connected anchoring plates 1 and bearing metal plates 4 slid from above onto the mounting elements 2, attached to: anchor plates 1.

The design of the connection module enables easy connection and disconnection of vertical reinforced concrete column S and horizontal reinforced concrete beams P.

Industrial applicability

The connection module according to the invention finds use in the construction of both temporary and permanent buildings.
