Patentagentfirmaet Magnus Jensens Eftf._ : (54) Armeret betonpæl.Patent agent company Magnus Jensen's Eftf._: (54) Reinforced concrete pile.
Len foreliggende opfindelse angår en armeret betonpæl af den i krav l's indledning angivne art.The present invention relates to a reinforced concrete pile of the kind set forth in claim 1.
Ved sådanne pæle skal beslaget forankres i pælen på en sådan måde, at beslaget også kan optage påvirkninger ved trækbelastning i pælen. Hidtil er forankringen af beslaget i pælen sket ved hjælp af fastskruede forankringsjern, der placeres parallelt med pælens langsgående armering. Forankringsjernene, der er ca. 1 meter lange, benyttes i samme antal som pælens langsgående armering og er placeret mellem denne. Herved dannes en forholdsvis tæt armeringskurv, som vanskeliggør indføring af betonmasse. Ved trækbelastning af en sådan pæl vil påvirkningerne i pælens langsgående armering ikke blive direkte overført fra denne til beslaget, men overføres fra ar- 142465 - 2 - meringen til forankrings formene via betonen, der kun i meget begrænset omfang kan optage·trækpåvirkninger. Tilsvarende gælder ved nedramning af pælen, hvor slagenergien og trækpåvirkningerne gennem rekylvirkning ved ramningen fra de korte forankringsjern skal overføres til den langsgående armering via mellemliggende betonlag.For such piles, the bracket must be anchored to the pile in such a way that the bracket can also absorb impacts when the pile is loaded. To date, the anchorage of the bracket in the pole has been done by means of screwed-in anchorage which is placed parallel to the pole's longitudinal reinforcement. The anchors, which are approx. 1 meter long, is used in the same number as the longitudinal reinforcement of the pole and is placed between it. This creates a relatively dense reinforcement curve, which makes it difficult to insert concrete. Upon tensile loading of such a pile, the impacts in the longitudinal reinforcement of the pile will not be directly transferred from it to the bracket, but will be transferred from the reinforcement to the anchorage forms via the concrete, which can only to a very limited extent absorb tensile impacts. The same applies to the piling of the pile, where the impact energy and tensile effects through recoil effect on the pile from the short anchorage iron must be transferred to the longitudinal reinforcement via intermediate concrete layers.
Man har foreslået fastsvejsning af den langsgående arme-ring til beslaget. Svejsning giver imidlertid ikke den nødvendige styrke, og i de oftest forekommende tilfælde, hvor beslaget består af jern og armeringen af kvalitetsstål, er svejsningen kompliceret.It has been proposed to weld the longitudinal arm ring to the bracket. However, welding does not provide the necessary strength, and in the most common cases where the bracket consists of iron and the reinforcement of quality steel, the welding is complicated.
Formålet med opfindelsen er at anvise en armeret betonpæl af den omhandlede art, hvor armeringen og beslaget er sammenkoblet på en enkel og sikker måde.The object of the invention is to provide a reinforced concrete pile of the kind in which the reinforcement and bracket are connected in a simple and secure manner.
Dette opnås ifølge opfindelsen ved den i krav 1 anviste udformning. De opnåede fordele ved denne udformning er ganske væsentlige. Hovedarmeringen kan uden fuge forbindes direkte til beslaget i de områder, hvor kraftkoncentrationerne optræder, dvs., hvor sammenkoblingen med en anden pæls beslag sker.This is achieved according to the invention in the embodiment of claim 1. The benefits obtained from this design are quite significant. The main reinforcement can be connected directly to the bracket in the areas where the power concentrations occur, ie where the coupling with another pile bracket occurs.
Man undgår endvidere den komplikation, som udgøres af ekstra forankringsjern til beslagene, jf. eksempelvis DE-OS 2.013.953.Furthermore, the complication posed by extra anchoring iron for the fittings is avoided, cf. for example DE-OS 2,013,953.
Opfindelsen skal i det følgende forklares nærmere i forbindelse med tegningen, hvor fig. 1 viser den ene ende af en pæl ifølge opfindelsen set fra siden, fig. 2 et snit langs linien II-II i fig. 1, fig. 3 i større målestoksforhold et snit langs linien III-III i fig. 2, fig. 4 et forbindelseselement set fra siden og delvis gennemskåret, fig. 5 samme set fra oven, fig. 6 i perspektiv den ene ende af en anden udførelsesform for en pæl, fig. 7 i større målestoksforhold samme set fra enden, fig. 8 et snit langs linien VIII-VIII i fig. 7» fig. 9 et snit langs linien IX-IX i fig. 7, og fig.10 skematisk pælens beslag og armering, set fra siden.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail in connection with the drawing, in which: FIG. 1 is a side view of one end of a pile according to the invention; FIG. 2 is a section along line II-II of FIG. 1, FIG. 3 is an enlarged sectional view taken along line III-III of FIG. 2, FIG. 4 is a side elevational view, partially cut in, FIG. 5 shows the same from above; FIG. 6 is a perspective view of one end of another embodiment of a pile; FIG. 7 in a larger scale from the end, FIG. 8 is a section along line VIII-VIII of FIG. 7, FIG. 9 is a section along line IX-IX of FIG. 7, and fig.10 schematically the side bracket and reinforcement.
142465 - 3 - I fig. 1 er vist den ene ende af en betonpæl 1 med langsgående armeringsstænger 2. Stængerne 2 er i enderne forsynet med gevind 3 til samvirke med bøsninger 4, hvormed hver stang 2 forbindes med et beslag 5 ved enden af pælen. Beslaget kan udgøres af eksempelvis en pælsko, en pælspids eller en pællaske. I den viste udførelsesform er beslaget 5 en laske.142465 - 3 - In FIG. 1 is shown one end of a concrete pile 1 with longitudinal reinforcing bars 2. The rods 2 are provided at the ends with threads 3 for cooperating with bushings 4, whereby each rod 2 is connected to a bracket 5 at the end of the pile. The fitting may consist of, for example, a fur shoe, a fur tip or a fur bag. In the embodiment shown, the bracket 5 is a groove.
Denne består af en ydre ramme 6 med i det væsentlige pælens tværsnitsform og forsynet med en bund 7, der har opstående rørformede partier 8 placeret i rammens hjørner. De rørformede partier 8 er forsynet med indvendigt gevind 9.This consists of an outer frame 6 having substantially the cross-sectional shape of the pile and provided with a bottom 7 having upright tubular portions 8 located in the corners of the frame. The tubular portions 8 are provided with internal threads 9.
Bøsningen 4 omfatter, som det tydeligst fremgår af fig. 4 og 5, en rørformet del 10 med indvendigt gevind 11, en med udvendigt gevind 13 forsynet tap 12, der er koaksial med og anbragt i forlængelse af den rørformede del 10, samt et mellemliggende parti 14, der har ikke-cirkulært, eksempelvis fire-eller sekskantet tværsnit, til samvirke med eksempelvis en skiftenøgle. Gevindet 13 svarer til det indvendige gevind i rørpartiet 8, og gevindet 11 i bøsningen, der har retning modsat tapgevindet 13, svarer til det udvendige gevind 3 på armerings s tængerne 2. Tappen 12 er hensigtsmæssigt noget lasngere end bøsningens boring 15, således at bøsningen 4 ved montering af stængerne 2 i forhold til beslaget 5 kan skrues et antal gænger ind i beslaget, før stængernes gængede ender indføres i bøsningerne 10. Da tappen 12 eksempelvis har højregevind, og bøsningen da indvendigt har venstregevind, vil armeringsstængerne ved indskruning af forbindelseselementet skrues ind i bøsningen og derved forbindes effektivt med beslaget.The sleeve 4 comprises, as can be seen most clearly in FIG. 4 and 5, a tubular member 10 with internal thread 11, an external thread 13 provided with coaxial and extending extension of the tubular member 10, and an intermediate portion 14 having a non-circular, e.g. -or hexagonal cross-section, for cooperation with, for example, a wrench. The thread 13 corresponds to the internal thread in the pipe portion 8, and the thread 11 in the bushing, which is opposite to the tap thread 13, corresponds to the external thread 3 on the reinforcing tongs 2. The pin 12 is suitably somewhat looser than the bushing bore 15, so that the bushing 4 when mounting the rods 2 relative to the bracket 5, a number of threads can be screwed into the bracket before the threaded ends of the rods are inserted into the bushings 10. Since, for example, the pin 12 has a right-hand thread and the bushing has an internal left-hand thread, the reinforcing rods will be screwed in by screwing on the connecting element. into the bushing, thereby effectively connecting to the bracket.
På beslagets ydersider er ud for rørpartieme 8 udformet koblingsorganer 16 med hensigtsmæssigt rundt tværsnit. Ved sammenkobling af to med hinanden liggende ens beslag anbringes på to over for hinanden liggende koblingsorganer 16 et ikke vist laskejern, der udgøres af en plade med to boringer med en indbyrdes afstand svarende til afstanden mellem to koblingsorganer 16 på hver sit beslag.On the outer sides of the bracket, coupling means 16 of suitably round cross section are formed next to the pipe portions 8. When interconnecting two adjacent brackets, two opposite coupling members 16 are mounted on a welded iron, which is formed by a plate with two bores with a spacing corresponding to the distance between two coupling members 16 on each bracket.
Ved den i fig. 6-9 viste udførelsesform har.boringerne 17 for optagelse af armeringsstængernes 2 ender i beslaget større diameter end stængerne, og i mellemrummet mellem boringens 17 væg og stangen kan iskrues en bøsning med et udvendigt gevind 13 svarende til boringens 17 indvendige gevind 9 og et indven- - 4 - 1Λ2Α65 digt gevind 11 svarende til stangens 2 ydre gevind 3. Bøsningen 4 har til lettelse af iskruningen den ene ende affaset, og den anden ende er forsynet med en kærv 18.In the embodiment shown in FIG. 6-9, the bores 17 for receiving the ends of the reinforcing bars 2 have a larger diameter than the rods, and in the space between the wall of the bore 17 and the rod, a sleeve with an external thread 13 corresponding to the internal threads 9 of the bore 17 and an inner thread can be screwed in. - - 4 - 1Λ2Α65 thread 11 corresponding to the outer thread of the rod 2 3. The bushing 4 has one end beveled for ease of the ice curvature and the other end is provided with a notch 18.
Boringen 17 i beslaget 5 er ved den viste udførelsesform anbragt i bunden af et spor 19 med svalehaleformet tværsnit.The bore 17 of the bracket 5 is in the embodiment shown at the bottom of a groove 19 of dovetail cross-section.
Der findes sådanne diagonalt mod hinanden rettede spor i hvert af beslagets hjørner. Ved sporets 19 ydre ende er ved bunden og/eller sidevæg eller -vægge udformet mindst én udskydende læbe 20, der er således udformet, at den ved ombukning kan bringes til at fastlåse en i sporet 19 indskudt kile 21.There are such diagonally directed grooves in each corner of the bracket. At the outer end of the groove 19, at least one protruding lip 20 is formed at the bottom and / or side wall or walls, so that it can be caused to lock a wedge 21 inserted in the groove 19 by bending.
Denne har i overensstemmelse med sporet dobbelt svalehaleformet tværsnit og er beregnet til at sammenkoble to mod hinanden anbragte beslag 5.This has a double dovetail cross-section, in accordance with the groove, and is intended to interconnect two brackets 5 arranged one against the other.
En pæl ifølge opfindelsen kan fremstilles på følgende måde:A pile according to the invention can be prepared as follows:
Armeringsstængerne afskæres til nøjagtige mål i det væsentlige svarende til pælens længde og forsynes med ydre gevind i begge ender, hvis pælen skal forsynes med beslag i hver ende, som vist i fig. 10. Over armeringsstængerne 2 skydes en bøjleformet tværarmering 25, som på passende måde fastgøres til stængerne, når disse er fikseret i korrekt indbyrdes stilling.The reinforcing bars are cut to exact dimensions substantially equal to the length of the pile and provided with external threads at both ends if the pile is to be fitted with brackets at each end, as shown in FIG. 10. Above the reinforcing bars 2, a hanger-shaped cross reinforcement 25 is slid, which is suitably attached to the bars when fixed in the proper mutual position.
Over stængernes 2 gevindender føres derefter beslagene 5, til stængernes endeflader ligger i et plan sammenfaldende eller noget under sporenes 19 bundflade. I rummet mellem boringerne 17 i beslagene og armeringsstængerne 2 indføres udefra bøsningerne 4, der frembringer en meget effektiv forbindelse mellem armeringsstængerne og beslagene, og som derved kan optage de store belastninger, der kan blive tale om. Til sidst placeres den med beslag forsynede armeringsenhed i en form, og betonstøbningen foretages.Brackets 5 are then passed over the thread ends of the rods 2 until the end faces of the rods lie in a plane coincident or somewhat below the bottom surface of the grooves 19. In the space between the bores 17 in the brackets and the reinforcing bars 2, the bushings 4 are introduced from the outside, which produce a very effective connection between the reinforcing bars and the brackets, and which can thus absorb the large loads that can be involved. Finally, the reinforced reinforcing unit is placed in a mold and the concrete casting is made.
