Abstract
The invention concerns a fixed torque nut and bolt connection (3) for attaching roof beams (1) of a roof construction framework to pillar constructions (5), in which every nut and bolt connection (3) has an element (17) made of a material that can be melted away. This melts away at a temperature of at least 100 degrees C, after which the roof beams (1) of the roof construction come free of the nut and bolt connections (3) and the pillar constructions (5) and fall to the ground. This means that the pillar constructions will not bend as the beams come free.<IMAGE>

MOMENTVASTE MOERBOUTVERBINDING VOOR HET BEVESTIGEN VAN DAKLIGGERS
VAN EEN RAAMWERK AAN KOLOMCONSTRUCTIES
De uitvinding betreft een momentvaste moerboutverbinding voor het bevestigen van dakliggers van een raamwerk aan kolomconstructies van industriële gebouwen, die uit meerdere door brandwerende wanden van elkaar gescheiden ruimten bestaan.
Het voornaamste doel der uitvinding is de dakliggers derwijze aan de kolomconstructies te bevestigen dat in geval van brand de tussen de dakliggers en de kolomconstructies aangebrachte moerboutverbindingen door de ontwikkelde warmte loskomen en de dakliggers van de kolomconstructies vrijkomen en neervallen, zonder dat de kolomconstructies een accidentele sollicitatie ondergaan.
Hierdoor wordt het mogelijk de brandbestendige kolomconstructies in de brandwerende wanden in te werken zonder dat deze bij brand worden omgetrokken.
Gekend is het dakliggers van een gebouw dat uit meerdere door brandwerende wanden van elkaar gescheiden ruimten bestaat, door middel van moerbouten te bevestigen aan stalen kolommen die aan beide zijden van genoemde wanden zijn opgesteld. Een belangrijk nadeel hiervan is dat in geval van brand de dakliggers en de kolommen door de ontstane hitte doorbuigen en volledig verloren gaan. Doordat de kolommen op een afstand van de wanden worden opgesteld blijven de wanden weliswaar overeind en wordt de beschadigihg ervan beperkt zodat de brand beperkt blijft tot de ruimte waar de brahd is ontstaan maar de opstelling van de kolommen op een afstand van de wanden vormt een hindernis langs de wanden, wanneer hiertegen stapelrekken of andere voorwerpen moeten worden geplaatst. Tevens wordt het nuttig grondoppervlak van de opslagruimten hierdoor kleiner.
Om hieraan te verhelpen is volgens het voornaamste kenmerk der uitvinding een momentvaste moerboutverbinding verwezenlijkt die is voorzien van een element van wegsmeltbaar materiaal dat bij een hitte-ontwikkeling van minstens 1000 C wegsmelt, waarbij de
<Desc/Clms Page number 2>
dakliggers van de dakconstructie na het wegsmelten van genoemd element van de moerboutverbinding en de kolomconstructies loskomt en naar beneden valt, zodat de vrijkomende kolomconstructies niet doorbuigen.
Als voorbeeld, zonder enig begrenzend karakter, volgt hierna een uitvoeriger beschrijving van een verkozen uitvoeringsvorm van de moerboutverbinding volgens de uitvinding. Deze beschrijving verwijst naar bijgevoegde tekeningen, waarin : fig. 1 een verticale dwarsdoorsnede van een scheidingsmuur met in vooraanzicht een kolomconstructie en een erop bevestigde dakligger van een dakconstructie voorstelt ; fig. 2 een vergrote doorsnede volgens de lijn 11-11 van fig. 1 weergeeft ; fig. 3 een vergrote doorsnede volgens de lijn 111-111 van fig.
1 voorstelt ; fig. 4 de eigenlijke moerboutverbinding in vergrote
EMI2.1
langsdoorsnede voorstelt en zoals aangeduid in de cirkel IV van fig. l fig. 5 er een vooraanzicht van weergeeft.
In deze figuren bemerkt men dat de dakligger 1 met I-vormig profiel van iedere dakconstructie, op ieder kopeinde is voorzien van een kopplaat 2 die door meerdere moerboutverbindingen 3 is bevestigd op de flens 4 van een kolomconstructie 5 met I-vormig profiel. Op genoemde flens 4 is een nok 6 bevestigd waarop de onderste boord van de kopplaat 2 van de dakligger 1 vrij rust. Ter versteviging van de dakconstructie is-een verstevigingselement 7 voorzien tussen de dakligger 1 van'de dakconstructie en de kopplaat 2 ervan. Iedere moerboutverbinding 3 bestaat uit een bout 8, met kop 9, steel 10, draadgedeelte 11, moer 12 en moerplaatjes 13-14. In de flens 4 van de kolomconstructie 5 is voor iedere moerboutverbinding 3 een opening 15 geboord waardoorheen de steel 10 van de bout 8 steekt.
In de kopplaat 2 van de dakconstructie is een opening 16 geboord waarvan de diameter groter is dan de kop 9 en het moerplaatje 13 van de bout 8. In deze opening 16 en over de steel 10 van de bout 8 is een smeltbus 17 aangebracht vervaardigd van een materiaal,
<Desc/Clms Page number 3>
bijvoorbeeld het genaamde ertelon, met een verwekings-of smeltpunt van minstens 1000 C. De smeltbus 17 is voorzien van een kraag 18 die tussen het moerplaatje 13 van de bout 8 en de kopplaat 2 van de dakligger 1 van de dakconstructie is geklemd. Bij voorkeur is een stalen ring 19 rand genoemde kraag 18 voorzien.
Bij brand in één der door de brandwerende wanden 20 gescheiden opslagruimten, zullen door de ontwikkelde hitte de smeltbussen 17 van de moerboutverbindingen 3 gaan smelten, terwijl de dakliggers 1 voldoende lang door middel van de nokken 6 op hun plaats worden gehouden, zodat de openingen 16 ten opzichte van de stelen 10 van de bauten 8 gecenterd blijven. De stalen ring 19 van iedere smeltbus 17 draagt er zorg voor dat de smelting van de smeltbussen gelijkmatig en radiaal verloopt. Wanneer de smeltbussen 17 zijn weggesmolten en de dakliggers 1 door de hitte beginnen door te buigen, zullen deze op de nokken 6 gaan scharnieren en zullen de kopplaten 2 van de dakliggers l over de bauten 8 wegschuiven, zodat de dakliggers 1 volledig loskomen van de kolomconstructies 5 en naar beneden vallen, zonder dat de kolomconstructies doorbuigen.
Hierdoor kunnen de kolomconstructies in de brandwerende wanden 20 worden ingewerkt, zonder dat het gevaar bestaat dat de wanden worden omgetrokken.
Bovendien wordt het nuttig oppervlak in de opslagruimten vergroot en vormen de kolomconstructies geen hindernis in deze opslagruimten. De funderingssokkels 21 van de kolomconstructies kunnen hierdoor ook betrekkelijk klein worden uitgevoerd.
Het spreekt vanzelf dat de smeltbussen gelijk welke vorm en
EMI3.1
en van gelijk welk geschikt materiaal afmetingen kunnen zijn vervaardigd.

TORQUE NUT BOLT CONNECTION FOR ATTACHING ROOF BEAMS
FROM A FRAMEWORK TO COLUMN STRUCTURES
The invention relates to a torque-resistant nut bolt connection for attaching roof beams of a framework to column structures of industrial buildings, which consist of several spaces separated from each other by fire-resistant walls.
The main object of the invention is to fix the roof beams to the column constructions that in the event of a fire, the nut bolts fitted between the roof beams and the column constructions become detached due to the generated heat and the roof beams of the column constructions are released and fall down, without the column constructions being an accidental application undergo.
This makes it possible to integrate the fire-resistant column constructions into the fire-resistant walls without being overturned in the event of a fire.
It is known that the roof beams of a building consisting of several spaces separated from each other by fire-resistant walls can be secured by means of cap screws to steel columns arranged on both sides of said walls. An important drawback of this is that in the event of fire, the roof beams and columns bend due to the heat generated and are completely lost. Because the columns are placed at a distance from the walls, the walls remain upright and their damage is limited, so that the fire is limited to the space where the brahd arose, but the arrangement of the columns at a distance from the walls is an obstacle. along the walls, when stacking racks or other objects are to be placed against it. It also reduces the useful ground surface of the storage spaces.
In order to remedy this, according to the main feature of the invention a torque-resistant nut bolt connection is provided, which is provided with an element of melt-away material that melts away at a heat development of at least 1000 ° C, whereby the
<Desc / Clms Page number 2>
roof beams of the roof construction after melting off said element of the cap screw connection and the column constructions come loose and fall down, so that the released column constructions do not bend.
As an example, without any limiting character, a more detailed description of a preferred embodiment of the cap screw connection according to the invention follows below. This description refers to the accompanying drawings, in which: Fig. 1 shows a vertical cross-section of a partition wall with a column construction in front view and a roof girder of a roof construction mounted on it; fig. 2 shows an enlarged section along the line 11-11 of fig. 1; fig. 3 is an enlarged sectional view taken on the line III-III of fig.
1 represents; Fig. 4 the actual nut bolt connection in enlarged view
EMI2.1
longitudinal section and as indicated in circle IV of Fig. 1 Fig. 5 shows a front view of it.
In these figures it is noticed that the roof beam 1 with I-shaped profile of each roof construction, is provided on each head end with a head plate 2 which is fixed by multiple nut bolt connections 3 to the flange 4 of a column construction 5 with I-shaped profile. A cam 6 is mounted on said flange 4, on which the bottom edge of the head plate 2 of the roof beam 1 rests freely. In order to reinforce the roof construction, a reinforcement element 7 is provided between the roof beam 1 of the roof construction and the head plate 2 thereof. Each nut bolt connection 3 consists of a bolt 8, with head 9, stem 10, thread part 11, nut 12 and nut plates 13-14. An opening 15 is drilled in the flange 4 of the column construction 5 for each cap screw connection 3 through which the stem 10 of the bolt 8 protrudes.
An opening 16, the diameter of which is larger than the head 9 and the nut plate 13 of the bolt 8, has been drilled in the head plate 2 of the roof construction. In this opening 16 and over the stem 10 of the bolt 8 a melting sleeve 17 is made made of a material,
<Desc / Clms Page number 3>
for example the named ertelon, with a softening or melting point of at least 1000 C. The melting sleeve 17 is provided with a collar 18 which is clamped between the nut plate 13 of the bolt 8 and the head plate 2 of the roof beam 1 of the roof construction. Preferably, a steel ring 19 edge said collar 18 is provided.
In the event of a fire in one of the storage areas separated by the fire-resistant walls 20, the heat generated will cause the melting sleeves 17 of the cap screw connections 3 to melt, while the roof beams 1 are held in place by means of the cams 6 for a sufficient length of time, so that the openings 16 remain centered with respect to the stems 10 of bauties 8. The steel ring 19 of each melting sleeve 17 ensures that the melting of the melting sleeves is uniform and radial. When the melting sleeves 17 have melted away and the roof beams 1 start to bend by the heat, they will hinge on the projections 6 and the head plates 2 of the roof beams 1 will slide over the bends 8, so that the roof beams 1 completely separate from the column structures 5 and fall down without the column structures bending.
As a result, the column constructions can be incorporated into the fire-resistant walls 20, without the danger of the walls being pulled over.
In addition, the useful area in the storage spaces is increased and the column constructions are no obstacle in these storage spaces. The foundation bases 21 of the column structures can hereby also be made relatively small.
It goes without saying that the melting cans have any shape and form
EMI3.1
and dimensions of any suitable material.
