Description

Vynález se týká suchých spojov plošných dielcov, najma stavebných panelov, ktoré přenáša.jú Smykové sily v kontaktněj rovině prvkov.The invention relates to dry joints of sheets, in particular building panels which transmit shear forces in the contact plane of the elements.

Dopolia! známe spoje sa realizujú vytvořením betonových nevystužených, připadne vystužených hmoždiniek v kontaktných škárach prvkov na celú šířku škáry alebo na jej časť, poprépade zvarenlm šikmých prútov, prenášajúcich hlavně ťahyalebo zvarením ocelových prípravkov rSzneho tvaru zakotvených do betonu. Betonové hmoždinky majú nevýhodu v zniženej únosnosti spoja oproti ostatnej konštrukcii aspoň o 50 % bez možnosti dodatočnej kontroly kvality spoja a vyžadujú mokrý proces.Dopol! The known joints are realized by forming unreinforced or reinforced concrete dowels in the contact joints of the elements over the whole or part of the joint width, or by welding the inclined bars, mainly transferring or welding the steel jigs of various shapes anchored to the concrete. Concrete dowels have the disadvantage of reducing the load-bearing capacity of the joint by at least 50% compared to the other construction without the possibility of additional quality control of the joint and require a wet process.

Spojovanie šikmých prútov, alebo ocelových prípravkov rozneho tvaru pomocou zvaru je velmi pracné, lebo celú šmykovú silu musia prenášať zvary převedené na stavbě.Joining angled bars or steel jigs of various shapes using a weld is very laborious, as the entire shear force must be transferred by the welds transferred on site.

Vyššie uvedené nedostatky sú odstránené suchým spojom plošných dielcov podía vynálezu, podstatou ktorého je dvojica zrkadlovo vedla seba umiestených telies, zakotvených v plošných dielcoch sústavou pozdížných a priečnych prútov tak, že pozdížne prúty sú převlečené cez otvory v telesách tvaru U a priečne prúty oboplnajú pozdížne prúty nad a pod telesom tvaru U. Plošné dielce sú opatřené na plochách obrátených k sebe vybraniami, ktorých poudížna os je kolmá na střednicová rovinu dielcov.V týchto dielcov sú zařazené společné kliny, dosadajúce na dvojicu ploch vybraní, ktoré m6žu byt kolné alebo šikmé k rovino styčnej škáry. Dielce sú symetricky orientované k rovině kolmej k styčnej škáry a k strednicovej rovině panelu. Kliny v takto prevedenom spoji prenášajú strihom pozdížnu šmykovú silu. Uvedený spoj je možné nadimenzovať na plnú hodnotu únosnosti spojovaných plošných prvkov bez zvarovania. Okrem toho je vylúčený mokrý proces pri vytváraní spojaThe above-mentioned drawbacks are eliminated by the dry joining of the panels according to the invention, which is based on a pair of mirrored side-by-side bodies anchored in the panels by a system of longitudinal and transverse rods so that longitudinal rods over and under the U-shaped body. joint interface. The parts are symmetrically oriented to a plane perpendicular to the joint and to the center plane of the panel. The wedges in such a joint transmit the shear force in shear. Said joint can be dimensioned to the full load-bearing capacity of the connected planar elements without welding. In addition, a wet process in forming the joint is excluded

205 449 a je umožněná dokonalá kontrola jeho kvality. Ďalej sa výrazné zvýši rýchlosť prevedenia spoja.205 449 and perfect quality control is possible. Furthermore, the speed of the coupling is considerably increased.

Na připojených výkresoch sú uvedené příklady suchých spojov montovaných stužujúcich stien. Na obr. 1 je znázorněné rozmiestnenie spojovacích článkov v styčných špárach medzi stěnovými panelmi, na obr. 2 je znázorněný c axonometrickom pohlade spojovací článek,ktorého dvojica ploch vybraní je kolmá na rovinu styčnej škáry a na obr. 3 je znázorněný v axonometrickom pohlade iný spojovací článok, ktorého dvojica ploch vybraní je šikmá na rovinu styčnej škáry.The attached drawings show examples of dry joints of prefabricated reinforcing walls. In FIG. 1 shows the arrangement of the links in the joints between the wall panels, FIG. 2 is an axonometric view of a connecting member whose pairs of recesses are perpendicular to the joint joint plane; and FIG. 3 is another axonometric view of another connection member whose pairs of recess surfaces are inclined to the joint joint plane.

Na obr. 2 je znázorněný a axonometrickom pohlade spojovací článok s plochami 5 vybraní kolmými na rovinu styčnej škáry, kde v prefabrikátech sú oproti sebe zabudované kovové telesá 1 profilu D so žliabkom, ktoré sú do prefabrikátov zakotvené bez zvarovania pomocou zvislých průtov 3, obepnutých kotevnými prútati 4,In FIG. 1 shows the arrangement of the links in the joints and the forces acting on them. In FIG. 2 shows an axonometric view of a connecting element with surfaces 5 recessed perpendicular to the plane of the joint joint, in which precast metal elements 1 of the D-shaped groove are embedded in each other and are anchored to the precasts without welding by vertical projections 3 surrounded by anchoring rods 4;

Zvislé prúty 3 sú převlečené otvormi v telese K Po přiložení susedného prefabrikátu vzniká v mieste protilehlých vybraní telies .1 otvor, do ktorého sa zarazia dva kliny 2. Kliny 2 musia mat takú pevnost, aby preniesli na střih celú požadovaná šmykovú silu.The vertical bars 3 are discharged through openings in the body K When an adjacent prefabricated piece is placed, a hole is formed at the opposite recesses of the bodies 1 into which two wedges 2 are driven. The wedges 2 must have sufficient strength to transmit all the required shear force.

V případe nepřesného osadenia prefabrikátov vo vodorovnou smere sa použijú širšie alebo užšie kliny 2, v zvislom smere sa nerovnosti vyrovnávajú tenkými podložkami polovičnej šířky otvoru. Stabilizácia klinov 2 sa dosiahne bodovými zvarmi, lepením a pod. Na obr.In the case of inaccurate installation of prefabricates in the horizontal direction, wider or narrower wedges 2 are used, in the vertical direction the unevenness is compensated by thin washers of half the width of the opening. Stabilization of the wedges 2 is achieved by spot welding, gluing and the like. In FIG.

je znázorněný v axonometrickom pohlade spojovací článok so šikmými plochami 5 vybrania na rovinu styčnej škáry. Ostatně časti sú zhoriné ako na obr. 2, len kliny 2 majú rybinový tvar ako styčné šikmé plochy 5. Týmto tvarou zabezpečujú aj sťahovanie spájených panelových dielcov.is shown in an axonometric view the connection member with the inclined surfaces 5 of the recess per the joint joint plane. Moreover, the parts are inferior as in FIG. 2, only the wedges 2 have a dovetail shape as the contact sloping surfaces 5. With this shape, they also ensure the contraction of the panels to be joined.

Vynález je možné použit všade tam, kde sa spájajú plošné betonové prefabrikáty, ktoré majú prenášať Smykové sily. V stavebníotve nájde uplatnenie pri spojování stěnových, dosko vých, lomenicových alebo škrupinových prefabrikátov. Ďalej sa zjednoduší tvar foriem pre betonáž panelov alebo jednoduchým sposobom pomocou výstupkov v bočniciach foriem je možné zabezpečit prrsnú polohu spojovacích telies. Zjednoduš! sa příprava výstuže pri výrobě panelov a urýchli sa postup montáže na stavbě. Navrhnuté klinové spoje vytvárajú předpoklady pre velmi presnú montáž.The invention can be used wherever flat concrete prefabricated elements intended to transmit shear forces are joined. It can be used in the construction industry for joining wall, plate, slate or shell prefabricates. Furthermore, the shape of the molds for the concreting of the panels is simplified, or by means of protrusions in the mold sides, it is possible to secure the breast position of the connecting bodies. Simplify! the preparation of the reinforcement in the manufacture of the panels and accelerate the assembly process on the site. Designed wedge joints create preconditions for very precise assembly.
