The specific embodiment
Defer to technique scheme, as shown in Figure 1 to Figure 3, a kind of telescopic builder's jack structure, comprise that one end is cemented in the Cantilever Beams 7 on building floor 2, the other end of Cantilever Beams 7 passes and perpendicular to the exterior wall 1 of building, Cantilever Beams 7 is brace foundations of whole scaffolding structure, and one is held level with both hands and is layered on building floor 2, and the U-shaped card 3 that is 25mm by a plurality of bar diameters is fastened on floor 2; The other end is through exterior wall 1, for scaffolding erecting.The length that this Cantilever Beams 7 stretches out wall part should be less than the part of not stretching out body of wall, through a large amount of practical applications, show that its ratio is 1:2～2.5 o'clock the bests.
At Cantilever Beams 7, stretch out on one end of exterior wall 1 and be provided with the vertical rod 6 perpendicular to Cantilever Beams 7, on the Cantilever Beams 7 of vertical rod 6 belows, be consolidated with the base plate 10 that width is not more than Cantilever Beams 7, on base plate 10, be vertically installed with the sleeve 9 that internal diameter is greater than vertical rod 6 external diameters, vertical rod 6 is sleeved in sleeve 9, and vertical rod 6 lower ends contact with sleeve 9 bottom surfaces.
Sleeve 9 adopts the mode of welding to be cemented on base plate 10, and base plate 10 is integral type structure.Welded construction intensity is high, and its position can be located accurately by pre-designed, and the optional scope of material is wide.Plug-in mounting vertical rod 6 in sleeve 9, the lower end of vertical rod 6 extend in sleeve 9, and contacts with sleeve 9 bottom surfaces.Sleeve 9 can adopt the penetrating high strength steel cylinder in two ends, and during welding, pad drops on sleeve 9 outsides and base plate 10 contact positions as far as possible, prevents that pad from affecting the insertion of sleeve 9.If any impacts such as pad, foreign material, make vertical rod 6 lower ends can not intactly drop on sleeve 9 bottom surfaces,, on base plate 10 upper surfaces, under pressure powerful above vertical rod 6, can cause vertical rod 6 to produce the situations such as slippage, fine motion, affect the safety of scaffold integral body.
In order to make radially not producing as much as possible of vertical rod 6 cheap, consider conveniently the requirement of installing, building, sleeve 9 internal diameters should slightly about vertical rod 6 external diameters, and both differences should remain on below 0.5mm as far as possible, make both can smooth and easy installation, and have minimum gap.
Consider the power producing when sleeve 9 is subject to vertical rod 6 overall radial and moves, at sleeve 9, be distributed with stiffener 15 around, stiffener 15 is modification of right-angled triangle plate, and two right-angle sides of stiffener 15 are fixed with sleeve 9 sides and base plate 10 upper surfaces respectively.Stiffener 15 also adopts the mode of welding to be fixed, and strengthened to a great extent sleeve 9 tolerance radially, and the length of sleeve 9 should be not less than 20cm, and this is to draw after considering length that existing vertical rod 6 is general and stressing conditions.Sleeve 9 is oversize affects the firm welding degree of its bottom, too short make vertical rod 6 and sleeve 9 bottoms stressed excessive.
The use of base plate 10 has disperseed power axial between vertical rod 6 and limit plug sleeve 9 effectively, more firm when this connected mode makes vertical rod 6 fixedly.After vertical rod 6 is arranged on sleeve 9, vertical rod 6 lower ends contact with base plate 10 upper surfaces, i.e. vertical rod 6 one is inserted into the end, tightly coordinates with sleeve 9, and vertical rod 6 radial loads can be directly delivered on base plate 10.The width of base plate 10 should not be greater than Cantilever Beams 7, is convenient to the installation of base plate 10 and fixes.
The Cantilever Beams 7 of selecting in the utility model is that cross section is the beam of I-shaped, and base plate 10 is selected rectangular base plate 10, and the width of base plate 10 is identical with the width of Cantilever Beams 7.On 10 4 jiaos of base plates, be provided with the bolt hole that runs through base plate 10 and Cantilever Beams 7, base plate 10 is fixed on Cantilever Beams 7 by bolt 14 and nut 13; Wherein nut 13 is positioned on base plate 10 upper surfaces.Bolt 14 nut 13 fastening means make base plate 10 be convenient to dismounting, and symmetrical fixed form greatly improved the fastness of base plate 10, can effectively transmit and disperse vertical rod 6 applies it radially, axial force.Bolt 14 upwards passes from the bolt hole of Cantilever Beams 7 bottoms when mounted, and nut 13 is fastening from top, is convenient to observe at any time the fastening degree of safeguarding base plate 10, also convenient installation.
More excellent in order to decompose the stressed scaffolding structure that makes of Cantilever Beams 7, on Cantilever Beams 7, be provided with wire rope 4.Because base plate 10 is connected with Cantilever Beams 7 is firm, so in this device, wire rope 4 can together be cemented on base plate 10.Exterior wall 1 one sides near building on sleeve 9 are provided with drawknot plate 11, and drawknot plate 11 is right-angled trapezium plate, and two right-angle sides of drawknot plate 11 are cemented in respectively on base plate 10 upper surfaces and sleeve 9 sides, and wherein longer right-angle side is cemented on base plate 10.On drawknot plate 11, offer the drawknot hole 12 that is parallel to base plate 10, be fixed with wire rope 4 in drawknot hole 12, the other end of wire rope 4, through the preformed hole on exterior wall 1, is fastened in exterior wall 1.The flower basket bolt 8 of adjusting wire rope 4 elasticities is also installed on wire rope 4.When mounted, the angle between wire rope 4 and Cantilever Beams 7 is 45～55 °, within the scope of this, can effectively disperse Cantilever Beams 7 stressed by wire rope 4, makes overall structure more firm.
Consider that base plate 10 is subject to force intensity, base plate 10 should adopt high strength steel to make, and should be undertaken comprehensively fixed by multipair bolt 14 nuts 13.In this device, the whole mechanism for fixedly vertical rod 6 is all at base plate 10, and not be used in, on Cantilever Beams 7, weld spacer bars, wire rope 4 draw rings etc. are set, only need on Cantilever Beams 7, offer bolt hole fixed base plate 10, structure is simpler, has improved dismounting efficiency.
Vertical rod 6 be arranged at least two in parallel, fixed by crossbeam 5 between vertical rod 6, overlaps more vertical rod 6 on vertical rod 6, forms scaffold.The scaffolding structure the utility model proposes can be controlled the position of inner side and outside vertical rod 6 accurately, guarantee the precision that vertical rod 6 is installed, quick and easy for installation, quality and performance are easy to guarantee, effectively reduce scaffold upright rod 6 due to the deviation manually fixedly causing, improved the overall security of scaffolding structure.
