Description

Uppfinnare: S-E V Svensson och R G Johansson Foreliggande uppfinning avser en anordfling for .att i samband med glidformsgjutning av vertikala betongkonstruktioner (vaggar el- ler petare) lyfta upp huvudsakligen helt eller delvis fardiga delar eller konstruktionsele- ment, som skola slutligt inga i byggnader -av olika slag. Lyftningen sker harvid fran ett Mgt plan, foretradesvis markplanet, pa vilket konstruktionselementens storre eller mindre, fabrikstillverkade delar monteras samman till en storre, slutgiltigt helt eller till storsta delen fardig konstruktionsenhet sasom derma skall inga i ,den fardiga byggnadskroppen. En typisk sadan konstruktionsenhet (byggnadsdel) är exempelvis tunga fackverkskonstruktioner av stal och halkar av stal eller betong, vilka med sina asar skola utgora barning for tak Over eller bjalklag mom en industribyggnad. Den vertikala lyftningen sker kontinuerligt utan omstallningar samtidigt med glidformsgjutningen av de betongvaggar eller betongpelare, som sedermera skola utgora bar-fling for den upplyftade konstruktionen. Lyftningen utfores darvid antingen till konstruktionens exakta slutlage i fardig byggnad eller till en hOjd, som med cirka en it tva meter overstiger slutla.get, till vilket sertare konstruktionen neclsankes och i vilket fall salunda byggnadens yttervaggar kunna glidformsgjutas till full h6jd upp till det blivande takets hajd da det galler upplyftning av en takkonstruktion. Inventors: SE V Svensson and RG Johansson. of different kinds. The lifting takes place from a Mgt plane, preferably the ground plane, on which the larger or smaller, factory-made parts of the construction elements are assembled together into a larger, finally completely or for the most part finished construction unit as there should be none in the finished building body. A typical such construction unit (building part) is, for example, heavy truss constructions of steel and slips of steel or concrete, which with their axes should constitute a child for roof over or beams of an industrial building. The vertical lifting takes place continuously without adjustments at the same time as the sliding mold casting of the concrete walls or concrete pillars, which will later constitute bar-fling for the raised construction. The lifting is carried out either to the exact end layer of the structure in the finished building or to a height which exceeds the end by about one to two meters, to which later the structure is lowered and in which case the outer walls of the building can be slid molded to full height up to the future roof. hajd as it involves lifting of a roof structure.

Det for uppfinningen vasentligt utmarkande är en kombination av tva separata lyftsystent ormfattande ett forsta system far lyftning av de tunga konstruktionselementen med stora lyftorgan och ett andra system for lyftning av glidformarna med sma lyftorgan, varvid de hada systemens lyftorgan aro av principiellt samma typ saint de hada systemen forsedda med var sin centrala kraftkall.a, vilka kraftkallor aro sa anordnade, aft de bada lyftsystemen kunna bringas att verka godtyckligt relativt varandra. The essential feature of the invention is a combination of two separate lifting systems comprising a first system for lifting the heavy construction elements with large lifting means and a second system for lifting the sliding molds with small lifting means, the lifting means of the two systems being of essentially the same type as the had the systems are each provided with a central power call, which power calls are so arranged, so that the two lifting systems can be made to operate arbitrarily relative to each other.

I anslutning till denna kombination kunna separata glidformar med ok for andra i byggnadsverket ingaende vertikala vaggar, pelare eller balkar av betong vara upphangda i for lyftning avsedda konstruktionselement. In connection with this combination, separate sliding molds with yokes for other vertical cradles, pillars or beams of concrete entering the structure may be suspended in structural elements intended for lifting.

Kombinationen; ifraga kan aven omfatta anordningen av arbetsplan, som aro uppburna av konstruktionsefementen och fran vilka for glidformsgjutningen nodvandiga arbetsoperationer utfaras, vilka arbetsplan utgoras antingen av overliggande stallningar eller hangstallningar. The combination; may also comprise the arrangement of work planes, which are supported by the structural elements and from which work operations necessary for the sliding mold casting are performed, which work planes consist of either overlying stables or hanging stables.

Fordelar och nya effekter med foreliggande uppfinning aro hi. a. foljande: De tunga kunstruktionselementen kunna sammanbyggas pa ett lagt plan, vanligen markplanet, vilket arbete salunda blir enkelt, billigt och tidsbesparande; i annat fall skulle hoga montagestallningar eller kostsamma montagekranar eller liknande erfordras. Advantages and novel effects of the present invention aro hi. a. the following: The heavy construction elements can be assembled on a laid surface, usually the ground level, which work will thus be simple, cheap and time-saving; otherwise, high mounting frames or expensive mounting cranes or the like would be required.

Alit egentligt montagearbele for saval den tunga konstruktionen som glidformarna, etc. utfores ph markplanet, vilket innebar ringa risker far olyeksfall. e) Ett byggnadsverk kan i en. enda kontinuerlig, principiellt enkel, arbetsoperation till sina huvuddelar mycket snabbt fardigstallas till full hojd ,och komma under tak; yttervaggar och tak utgora salunda ett slutet utrymme som latt kan hallas uppvarmt for invandigt vidare byggn,adsarbete under den kalla arstiden. Alit actually assembly work for saval the heavy construction such as the sliding molds, etc. is carried out ph ground level, which meant little risk of accident. e) A structure may in a. single continuous, principally simple, work operation to its main parts very quickly completed to full height, and come under cover; Exterior walls and roofs thus form an enclosed space that can easily be kept heated for interior further construction, as work during the cold season.

Under lyftningens gang kan konstruktionen anvandas som arbetsplan for arbetsoperationerna med sjalva glidformsgjutningens genomforande och som upplag for material. During the lifting process, the construction can be used as a work plan for the work operations with the actual slide mold casting and as a support for materials.

Konstruktionen kan med enkla anordningar mot de glidgjutna vaggarna eller pelarna utgora en horisontell styv skiva for overforande av horisontella vindkrafter fran vindbelastad vagg till mot derma vinkelrat vagg eller annan glidgjuten byggnadsdel. The construction can with simple devices against the slip-cast cradles or pillars form a horizontal rigid disc for transmitting horizontal wind forces from wind-loaded cradle to against this angled cradle or other slip-cast building part.

I) All lyftaing sker kontinuerligt utan om- 2— — tagning med lyftanordningarna och utan pall-fling, varigenom eljest nodvandiga uppehall i arbetet bortfalla. I) All lifting takes place continuously without reassembly with the lifting devices and without pallet flaking, as a result of which otherwise necessary breaks in the work are eliminated.

Genom anvandningen av i princip likarlade lyftanordningar for lyftningen av den tunga konstruktionen respektive glidformarna un:derlattas och sakerstalles let rent praktiska genomforandet av hela lyftningsproceduren. Through the use of basically similar lifting devices for the lifting of the heavy structure and the sliding molds, respectively, the purely practical implementation of the entire lifting procedure is omitted and secured.

Genom anvandningen av lyftanordningar (lyftare) med olika enskilda lyftkapaciteter kan den nodvandiga totala lyftkraften pa ett rationellt salt erhallas med ett minimum av enskilda lyftpunkter, vilket forbilligar lyftningen och gOr det praktiska genomforandet enkelt med minsta arbetskraft. Through the use of lifting devices (lifters) with different individual lifting capacities, the required total lifting force on a rational salt can be obtained with a minimum of individual lifting points, which reduces the lifting and makes the practical implementation easy with the least manpower.

Genom lamplig fOrdelning av stora, respektive smâ lyftare kunna de verkliga upptradande belastningarna pa dessa enkelt sh avpassas att, exempelvis vid hydrauliska lyftare, del tillforda oljetrycket fran oljetryckpumpen (kraftkallan) i det narmaste vara praktiskt target konstant for samtliga lyftare i de hada lyftsystemen for att astadkomma en jaunt lyftning. By suitable distribution of large and small lifters, the actual load-bearing loads on these can easily be adapted to, for example in hydraulic lifters, supply the oil pressure from the oil pressure pump (the power source) almost be practically constant for all lifters in the had lifting systems. achieve a jaunt lift.

Alla i det totala lyftsystemet inghende lyftare kunna effektivt utrrYttjas till ungefar samma verkningsgrad och armed aven de stod, pa vilka lyftarna klattra; inga for lyftningen erforderliga anordningar blir shlunda overdimensionerade, varigenom baste {aniska och ekonomiska resultat uppnas. All lifters not included in the total lifting system can be effectively eradicated to approximately the same efficiency and armed even as they stood on which the lifters climb; no devices required for lifting are thus oversized, thereby achieving basic and economical results.

Genom att lyftningen sker med tva i princip separata lyftsystem (ett for den tunga konstruktionen och ett for glidformarna) kan de hada systemen funktionera oberoende av varandra, dvs. lyftningen av konstruktionen och av glidformarna kan ske godtyckligt relativt varandra; detta underlattar samordningen under glidgjutningens gang av de liar-for erforderliga arbetsoperationer, som kontinuerligt eller diskontinuerligt med olika tidsintervall skall utforas. 1) Nar som heist under lyftningens och glidgjutningens gang kan ettdera av lyftsystemen stoppas upp tillfalligt eller slutligt. Because the lifting takes place with two basically separate lifting systems (one for the heavy construction and one for the sliding molds), the two systems can function independently of each other, ie. the lifting of the structure and of the sliding molds can take place arbitrarily relative to each other; this facilitates the coordination during the slip casting of the required work operations, which are to be performed continuously or discontinuously at different time intervals. 1) When lifting during the lifting and sliding casting process, one of the lifting systems can be stopped temporarily or permanently.

Efter avslutad glidgjutning till full hojd kan glidformarna stannas och den tunga konstruktionen direkt lyftas eller sankas till tinskat slutlage. After sliding casting to full height, the sliding molds can be stopped and the heavy construction directly lifted or lowered to a thinned finish.

Nar den tunga konstruktionen natt sitt slutliga hojdlage stannas den och lyftningen av glidformarna kan direkt fortsatta till full hojd. When the heavy structure reaches its final height, it stops and the lifting of the sliding molds can proceed directly to full height.

Genom de .enskilda lyftpunkterna kan enkelt en exakt finjustering av slutlh.get ske. Through the individual lifting points, an exact fine adjustment of the final lift can easily take place.

Med bibehallande av principen med tva separate lyftsystem med var sin centrala kraftkalla kan de bada systemen via en forbindelseledning (exempelvis oljeledning vid hydrauliska lyftare) med avstangningsanordningar sammankopplas sh att, om ena kraftkallan skittle komma ur funktion, den andra fortfarande kan lyfta hada lyftargrupperna godtyckligt relativt varandra. By maintaining the principle of two separate lifting systems, each with its own central power source, the two systems can be connected via a connecting line (for example oil line for hydraulic lifters) with shut-off devices so that, if one power source skittle comes out of operation, the other can still lift the lifting groups arbitrarily. each other.

Vid de tillfallen under arbetets ghng, dh. sa befinnes praktiskt lampligt, kan de hada systemen koras fullt synkront. On those occasions during the work ghng, ie. so found to be practically appropriate, the hada systems can be run fully synchronously.

Den tunga konstruktionen kan under lyftningen direkt utnyttjas for upphangning av ytterligare glidformar for vertikala frista- ende eller med yttervaggar och pelare sammanhangande huvudsakligen invandiga be- tongkonstruktioner, varvid sal-anda for dessa glidformar sarskilda lyftapparter ej erfordras; harigenom majliggores exempelvis ett enkelt satt att Oven glidformsgjuta horisontella betongbalkar inuti byggnaden. The heavy structure can be used directly during lifting for suspending additional sliding molds for vertical freestanding or with outer walls and pillars connected mainly internal concrete constructions, whereby the different lifting parts for these sliding molds are not required; This allows, for example, a simple method of casting horizontal concrete beams inside the building.

Anordningen askadliggores schematiskt bifogade ritning. Som exempel har for enkelhetens skull veils en barande storre takkon- struktion av stE besthende av svetsade sadel- formade balker med ovanpaliggande asar och vindforband. I princip blir anordningen den- samma vid fackverkkonstruktioner eller be- tongbalkar saval fOr tak som for bjfilklag. 130 ritningen ha lyftanordningarna antagits vara hydrauliska domkrafter, men uppfinningen Or givetvis anvandbar Oven vid andra typer av lyftanordningar verkande enligt klatterprincipen. The device is schematically illustrated in the diagrammatic accompanying drawing. As an example, for the sake of simplicity, a load-bearing larger roof construction of stone has been proposed, consisting of welded saddle-shaped beams with overhead axles and wind joints. In principle, the device is the same for truss constructions or concrete beams, both for roofs and for beams. 130 of the drawing, the lifting devices have been assumed to be hydraulic jacks, but the invention is of course applicable to other types of lifting devices operating according to the climbing principle.

Ritningen visar en vertikalsektion av ett byggnadsverk under upplyftningen av takkonstruktionen och glidformsgjutningen av vaggar och pelare av betong. The drawing shows a vertical section of a structure during the lifting of the roof structure and the sliding molding of concrete cradles and pillars.

Ph ritningen betecknas de konstruktionselement med 1, som skola lyftas i samband med glidformsgjutningen, med 8 glidformarna, med 2 och 2a lyftanordningarna eller lyftarna, med 3 och 3a de tryckta standare eller dylikt, vilka lyftarna Oro a.nbringade och klattra samt med 4 och 4a de centrala kraftkallor, med vilka lyftningen regleras. In the drawing the design elements are the construction elements with 1, which are to be lifted in connection with the sliding mold casting, with the 8 sliding molds, with the 2 and 2a lifting devices or lifters, with 3 and 3a the printed stands or the like, which the lifts are mounted and climb and with 4 and 4a the central power sources, with which the lifting is regulated.

Vid hydrauliska lyftare 2 och 2a utgoras krafteentralerna 4 och 4a av oljetryck-pumpar, till vilka lyftarna 2 och 2a Oro anslutna via oljeledningarna 5 och 5a. In the case of hydraulic lifters 2 and 2a, the power stations 4 and 4a consist of oil pressure pumps, to which the lifters 2 and 2a Aro are connected via the oil lines 5 and 5a.

Vid den tunga konstruktionsenheten 1 med sine asar la och vindforband Oro infastade stone lyftare 2, som klattra ph sthndarna 3. At the heavy construction unit 1 with its axles and wind joints Oro attached stone lifters 2, which climb ph sthndarna 3.

Dessa lyftare 2 Oro via oljeledningen 5 anslutna till sin gemensamma oljepump 4. Glid- formarna 8 for vaggarna 11 och pelarna 12 uppbares av ok 9, i -vilka Oro anbringade mind-re lyftare 2a klattrande ph sthndarna 3a och anslutna till den gemensamma oljepumpen 4a via oljeledningarna 5a. I detta exemplifierade fall Oro samtliga lyftare 2 och 2a place- rade i takstolsindarna respektive i glidformen for yttervaggarna. Lyftningen av takkonstruktionen och glidformarna langs yttervaggarna sker alas& med tvh skilda hydrauliska system, system 2, 4, 5 respektive system 2a, 4a, 5a. Genom f8rbindelseledningen 6 kunna de bada systemen sammankopplas och medelst avstangningskranarna 7 kunna Oven sh.lunda de hada systemen kiiras samtidigt och synkront — — om sit Onskas och vidare kunna cla aven, om erta pumpen skulle komma ur funktion, de bada systemen koras separat var for sig eller samtidigt med enbart en pump 4 eller 4a. These lifters 2 Oro via the oil line 5 connected to their common oil pump 4. The sliding molds 8 for the cradles 11 and the pillars 12 are supported by yoke 9, in which Oro mounted smaller lifters 2a climbing the poles 3a and connected to the common oil pump 4a via the oil lines 5a. In this exemplified case, Oro all lifters 2 and 2a are placed in the roof truss sensors and in the sliding shape for the outer walls, respectively. The lifting of the roof structure and the sliding molds along the outer walls takes place alas & with two different hydraulic systems, systems 2, 4, 5 and systems 2a, 4a, 5a, respectively. Through the connecting line 6 the two systems can be connected and by means of the shut-off valves 7 the two systems can also be run simultaneously and synchronously - - if their desired and further can also, even if the pump should come out of operation, the two systems are run separately. alone or simultaneously with only a pump 4 or 4a.

Med 13 betecknas ett arbetsplan eller overliggande stallning pa den upplyftade kon- struktionen, pa vilket arbetsplan material- transport och annat arbete for glidformsgjutningen utfores. Aven hangstallningar kunna forekomma. Pa takkonstruktionen aro foretradesvis vid takstolarnas andar momentstyvt infastade gejdrar eller stod 14, vilka ej aro fastade vid glidformen utan endast glidbart stoda mot denim och vilkas andamal ar att overfora horisontalkrafter fran den glidgjut- na vaggen eller pelaren till takkonstruktionen och vice versa. 13 denotes a work plan or overlying position on the raised structure, on which work plan material transport and other work for the molding is performed. Hanging stands can also occur. On the roof structure there are preferably rigidly attached guides or stands 14 attached to the spirits of the roof trusses, which are not attached to the sliding form but only slidably stand against denim and whose purpose is to transmit horizontal forces from the sliding cradle or pillar to the roof structure and vice versa.

PA ritningen visas aven en i delta fall fristaende invandig betongkonstruktion 11a, som glidgjutes med glidformarna 8a, vilkas ok 9a tiled hangslen 10 aro upphangda i takstolarna 1 eller dessas agar la. De invandigt glidforms- gjutna: delarna lla kunna under lyftningens gang avslutas och paborjas igen pa godtyckliga nivaer, exempelvis betongbalkar for blivande bjalklag i de olika va.ningsplanen. The drawing also shows an in some cases an independent internal concrete structure 11a, which is slid cast with the sliding molds 8a, the yokes 9a of the hinge 10 are suspended in the roof trusses 1 or their agar 1a. The internally sliding molded parts can be completed and re-drilled during the lifting process at arbitrary levels, for example concrete beams for future joists in the different floor plans.

Nar takkonstruktionen upplyfts till sitt slutliga permanenta hojdlage avslutas lyftningen av densamma, dvs. lyftningssystemet 2, 4, liar lyft fardigt, och glidformslyftningen fortsattes direkt med lyftnirtgssystemet 2a, 4a, 5a tills vaggarna nalt upp till i hojd med blivande takinkladnad. When the roof structure is raised to its final permanent height layer, the lifting is terminated by the same, ie. the lifting system 2, 4, liar finished lifting, and the sliding form lifting was continued directly with the lifting system 2a, 4a, 5a until the cradles reached up to a height with future roof loading.

Ha yttervaggarna glidgjutits :direkt upp till full h8jd men vaggpelarna :avslutats i h8jd med slutligt upplag fOr takkonstruktionen och da salunda takkonstruktionen upplyfts till en hojd overstigande dess slutliga hojdlage, skall takkonstruktionen efter avslutad glidformsgjutning sankas till upplaggning pit vaggpelarna. Detta sker dit med det hydra.uliska systemet 2, 4, 5, varvid lyftarna 2 aro av reversibel typ, dvs. man later dem .direkt pit sina standare 3 klattra aven nedat. Det la.mpligaste torde harvid vara att glidformarna nedmonteras, innan taksankningen sker. Detta ar dock ej nodvandigt om blott da den yttersta takasen ha Iran borjan ligger tillraekligt langt in pa takstolarna for att ej yttervaggens ok 9 skall komma hindrande i vagen. If the outer walls have been slid cast: directly up to full height but the cradle pillars: finished at the height with the final support for the roof structure and when the roof structure is raised to a height exceeding its final height layer, the roof structure shall be lowered to the cradle piles after completion of sliding mold casting. This is done there with the hydraulic system 2, 4, 5, the lifters 2 being of a reversible type, i.e. you let them .direkt pit their stands 3 climb aven down. The most appropriate thing would be for the sliding molds to be dismantled before the roof is lowered. However, this is not necessary only if the outermost roof has Iran at the beginning, it is sufficiently far inwards on the trusses so that the yoke of the outer wall 9 does not obstruct the road.
