Abstract
Vynález rieši problém hospodárného spojenia ocelového štípa s ocelovými hlavicemi. Podstata vynálezu spočívá v tom, že spoj pre spojenie ocelového štípa s ocelovými hlavicemi pre uloženie železobetonových hřibových a trámových stropov je tvořený manžetou, nasunutou na ocelový štíp a pevne s ním spojenou, pričom k vonkajšiemu obvodu manžety je pevne prichýtená ocelová hlavica.The invention solves the problem of economical connection of steel studs with steel heads. The essence of the invention lies in the fact that the connection for connecting steel studs with steel heads for supporting reinforced concrete mushroom and beam ceilings is formed by a sleeve, pushed onto the steel stud and firmly connected to it, while the steel head is firmly attached to the outer circumference of the sleeve.
Description
Vynález rieši spojenie ocelového štípa s ocelovými hlavicami slúžíacímí k ůloženíú železobetonových hřibových', a trámových stropov budov.The invention solves the connection of a steel chip with steel heads used for laying of reinforced concrete mushroom and beamed ceilings of buildings.
Doteraz používané pripojenie bolo riešené tak, že sa súčasti hlavice pripájali priamo na ocelový štíp. Tento sposob pripájania vyvolával v štípe vysoké sústredené napátie v mieste zvaru. Takto boli značné odčerpané rezervy pevnosti ocele štípa, ktoré sú potřebné pre ostatně druhy namáhania. Doteraz známe použité spoje ocelových hlavic a ocelových stípov sú priamé t. j. ocelový štíp je spojený s ocelovou hlavicou priamo, bez manžety.The connection used up to now was designed so that the head components were connected directly to the steel chip. This type of connection caused a high concentrated stress at the location of the weld. In this way, the considerable strength reserves of the splitting steel required for the other types of stresses were exhausted. The known joints of the steel heads and the steel columns known so far are straight t. j. the steel pin is connected to the steel head directly, without the collar.
Vyššie uvedený nedostatok v značnej miere odstraňuje spoj ocelového štípa s ocelovou hlavicou pre uloženie železobetonových hřibových a trámových stropov, ktorého podstata spočívá v tom, že je tvořený ocelovou manžetou nasunutou na ocelový štíp a pevne s ním spojenou. K vonkajšej ploché manžety je pevne prichytená ocelová hlavica.The aforementioned drawback largely eliminates the connection of the steel chip to the steel head for the placement of reinforced concrete mushroom and beam ceilings, which consists in that it consists of a steel sleeve pushed onto the steel chip and firmly connected thereto. A steel head is firmly attached to the outer flat collar.
Použitím spoja podta vynálezu sa asi páťnásobne zníži miestne napátie, pósobiace ohybom na stenu štípa a vyvolané zaťažením ocelověj hlavice. V dosledku toho je možné zmenšit prierez štípa, čím sa dosiahne zniženie jeho hmotnosti a tým úspora kovu.By using the joint according to the invention, the local stress caused by the bending on the wall of the graft and caused by the loading of the steel head is reduced by about five times. As a result, it is possible to reduce the cross-section of the graft, thereby reducing its weight and thereby saving metal.
Příklad spoja je schematicky znázorněný na výkrese, kde na obr. 1 je bočný pohlad na zvislý rez spoja pre hřibový strop, na obr. 2 je bočný pohlad na zvislý rez spoja pre trámový strop.An example of a joint is schematically shown in the drawing, where in FIG. 1 is a side elevational view of a joint for a mushroom ceiling; FIG. 2 is a side elevational view of a joint for a joist ceiling.
Spoj je tvořený ocelovou manžetou 1, například medzikruhového prierezu. Táto je nasunutá na ocelový štíp 2 a je s ním pevne spojená pomocou zvaru. K vonkajšej ploché manžety 1 je zvarom připojená ocelová hlavica 3, slúžiaca pre uloženie železobetonových stropov ako i pre pripojenie ocelových nosných konštrukcii.The joint is formed by a steel sleeve 1, for example an annular cross-section. This is slid onto the steel pin 2 and is fixed to it by welding. A steel head 3 for welding the reinforced concrete ceilings as well as the steel supporting structures is welded to the outer flat collar 1 by welding.
Zvarenie prvkov sa móže uskutečnit pri montáži ocelověj konštrukcie na stavbě, alebo manžeta 1 sa zvarí s ocelovou hlavicou 3 v dielni, kde je výhoda možnosti vyžihania, a takto připravená hlavica 3 sa potom montuje privarením k stojacemu osadenému štípu 2 na stavbě.Welding of the elements can take place when the steel structure is assembled on site, or the sleeve 1 is welded to the steel head 3 in the workshop where the advantage of the ironing is advantageous, and the head 3 so prepared is then welded to a stationary stepped pin 2 on site.
Vynález je možné využit hlavně v stavebníctve pri konstruovaní a montáži ocelových konštrukcii.The invention can be used mainly in the construction industry in the construction and assembly of steel structures.
