Abstract

One or more steps (1, 2) are formed on a building component comprising two interconnected rods. The free ends of the rods have fixtures for releasable attachment to step pins on steps arranged in an inclined position. The one rod supports a plank, whilst the other acts as a support for the first, activating the step pins which are partly encased by a fixture. The second rod fixture comprises two encompassing components turned away from each other for supporting or suspending attachment to a step pin.

Description

451 635 Metodens användbarhet begränsas dock på följande besvärande sätt då det gäller ingjutning av korta bultar. 1. Då bulten är införd i ett kort sk PERFÛ-rör enligt tidigare beskrivning, ligger det ofixerat och i det fall den innehåller större längd utanför borrhålet i förhållande till den ingjutna bultlängden vinklas genom övervikt bulten nedåt. Ett tidsödande uppriktningsarbete erfordras här för att få bulten stadigt och- i ett korrekt preciserat läge fixerad. 2. Vid insättning av bult i uppåtriktat hål glider bulten lätt ur den färska ingjutningsmassan enär bulten med sin ur borr- hålet utstickande ofta gängade del i sin helhet är relativt tung i förhållande till den ingjutna bultdelen. Här erfordras alldeles speciellt omfattande provisoriska upp- och infästnings- arbeten för att hålla bulten i avsett läge intill dess att bruks- massan bundit i erforderlig grad. 451 635 However, the usefulness of the method is limited in the following troublesome manner when it comes to casting short bolts. 1. When the bolt is inserted into a short so-called PERFÛ pipe as previously described, it lies unfixed and in case it contains a greater length outside the borehole in relation to the cast-in bolt length, it is angled downwards by the overweight bolt. A time-consuming straightening work is required here to get the bolt firmly and fixed in a correctly specified position. 2. When inserting a bolt in an upwardly directed hole, the bolt slides easily out of the fresh grouting mass, since the bolt with its often threaded part protruding from the borehole as a whole is relatively heavy in relation to the cast-in bolt part. Here, very particularly extensive temporary mounting and fastening work is required to keep the bolt in the intended position until the mortar has bound to the required degree.

Enligt uppfinningen föreslås för undvikande av dessa nackdelar och för vinnande av ytterligar fördelar ett hylsorgan utfört i korta avpassade längder enligt nedanstående beskrivning och bifogad rit- ning med A stycken figurer.According to the invention, in order to avoid these disadvantages and to gain additional advantages, it is proposed that a sleeve member be made in short adapted lengths according to the following description and the accompanying drawing with A pieces of figures.

Ett hylsorgan (1) utformas med inåt relativt stora styvt fjädrande anhåll (2) eller flikar så anordnade så att de centrerar den införda bulten (A), fixerar den och håller den i stadigt läge. Ãvensâ att ett liknande anhåll (2) eller flikar anordnas ut från hylsorganet (1) och fungerande såväl som gripklor hållande hylsan (1) fast mot borrhâlsvägg och distansorgan som garanterar en jämn bruksfyllning mellan hylsorganets mantelyta (1) och borrhâlsvägg. Hylsorganets yttre anhâll (2) vändes med spetsarna mot borrhålets mynning och de invändiga spetsarna mot dess botten. <4 Wi ...uAumfl-J. 451 615 Hylsorganet är utfört i ett relativt styvt material med anhållen så styvt fjädrande att det ger den inspänningseffekt som erfordras för att vid borrhâlsvägq hålla fast hylsorganet med bruksmassa och bult såväl vid horisontellt som uppåtriktat införd bult.A sleeve member (1) is formed with inwardly relatively large rigidly resilient stops (2) or flaps so arranged as to center the inserted bolt (A), fix it and hold it in a stable position. Also that a similar stop (2) or flaps are arranged out of the sleeve member (1) and functioning as well as gripping claws holding the sleeve (1) firmly against the borehole wall and spacers which guarantee an even use filling between the sleeve surface (1) and the borehole wall of the sleeve member. The outer stop (2) of the sleeve member is turned with the tips towards the mouth of the borehole and the inner tips towards its bottom. <4 Wi ... uAum fl- J. 451 615 The sleeve member is made of a relatively rigid material with the retaining so rigidly resilient that it provides the clamping effect required to hold the sleeve member with mortar and bolt at both drill holes and the bolt inserted both horizontally and upwards.

Hylsorganet framställes på materialbesparande och rationellt sätt genom att anhållen/flikarna stansas direkt ut ur dess mantelyta.The sleeve member is manufactured in a material-saving and rational manner by punching the stop / flaps directly out of its jacket surface.

I de därvid uppkomna hålen i godset kan bruksmassan pressas ut vid bultens indrivning och fylla utrymmet mellan rörorganet och borr- hålsvägg.In the holes thus formed in the goods, the working mass can be pressed out during the driving in of the bolt and fill the space between the pipe member and the borehole wall.

Fördelarna med hylsorganet kan i korthet sammanfattas sålunda: 1. lngjutning av korta bultar med bruksmassa i borrhål kan utföras på ett snabbt sätt med en jämn kringqjutning av bulten och exakt stadig fixering i avsett läge. 2. Hylsorganet medger att kortbult i uppåtriktat borrhål kan in-\ qjutas utan att extra speciella förfaranden som t ex uppallning och/eller kringkilning av bulten behöver vidtagas under bruke- _ massans första bindetid.The advantages of the sleeve member can be briefly summarized as follows: 1. Casting of short bolts with working mass in boreholes can be carried out in a fast manner with an even rotation of the bolt and precise fixed fixing in the intended position. 2. The sleeve member allows the short bolt to be inserted into an upwardly directed borehole without the need for extra special procedures such as piling up and / or wedging of the bolt during the first bonding time of the mortar.
