Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated:
Accompanying drawing is a kind of specific embodiment of the present invention, this embodiment comprises horizontal steel pipe 1 and vertical steel pipe 2, described horizontal steel pipe 1 and vertical steel pipe 2 form scaffold stand, the vertical angle place that described horizontal steel pipe 1 and vertical steel pipe 2 are formed is fixed with longitudinal steel pipe 3 by fastener, described longitudinal steel pipe 3 arranges formation arc-shaped from top to bottom in the same side of scaffold stand, and circular arc steel pipe 4 arc-shaped that longitudinally steel pipe 3 is formed is fixedly connected with longitudinal steel pipe 3 by fastener.Described circular arc steel pipe 4 comprises Circular Steel body 5, the lumps of wood 6 and bamboo slab rubber 7, and the inner arc surface of described Circular Steel body 5 is fixed with the lumps of wood 6, and the described lumps of wood 6 is fixed with bamboo slab rubber 7 by long steel nail.Described horizontal steel pipe 1 and vertical steel pipe 2 form in scaffold stand and are provided with normal direction steel pipe 10 along the normal orientation of circular arc steel pipe 4, one end of described normal direction steel pipe 10 is connected with circular arc steel pipe 4 by fastener 9, the other end is connected with scaffold stand, and described normal direction steel pipe 10 is arranged evenly along the external arc of circular arc steel pipe 4.
The present invention in use, goes out the parameter such as length, radian of circular arc steel pipe 4 according to project organization Size calculation, prefabricated moulding bed outside the venue, and it is prefabricated to carry out arc-shaped steel tube.Suppose that design arc radius is r, the lumps of wood 6 thickness is a, and bamboo slab rubber 7 thickness is b, and the diameter of circular arc steel pipe 4 is d, then radius R=the r+a+b+d/2 of prefabricated circular arc steel pipe 4, must guard against and structure design arc radius is thought by mistake be prefabricated circular arc steel pipe radius.
After scaffold support has been set up, the elevation of longitudinal steel pipe 3 is first gone out according to project organization Size calculation, accurately made the horizontal level of longitudinal steel pipe 3 by measurement of the level, adopt fastener 9 longitudinal steel pipe 3 to be connected to securely scaffolding steel pipe and comprise on horizontal steel pipe 1 and vertical steel pipe 2; By total powerstation, adopt coordinate method accurately to make the position of prefabricated curved steel tube, and circular arc steel pipe 4 is fixed on longitudinal steel pipe 3 by fastener 9.For strengthening the integral rigidity of exterior sheathing, reducing elastic deformation amount, on steel pipe, adding the tangential direction that normal direction steel pipe 10(is approximately perpendicular to this point of circular arc in length and breadth).Simultaneously in order to strengthen the load-bearing of exterior sheathing skeleton, be connected each other by fastener 9 between steel pipe with vertical steel pipe 2 in length and breadth, in order to ensure that safety is high, suggestion adopts two clamp styles (namely to add a fastener in the below of connection fastener, prop up connection fastener), to avoid slip phenomenon.In addition, fully take into account the line style requirement of the fish-bellied type trough girder of beam body, the circular arc steel pipe 4 that exterior sheathing is provided with is provided with bamboo slab rubber 7, utilize the toughness of bamboo slab rubber 7 by bamboo slab rubber arc curved, be fixed on the lumps of wood, such exterior sheathing just can adapt to changeable contour structures, of many uses.
In addition use exterior sheathing time should be noted that several in:
(1) form cage longitudinal steel pipe 3, horizontal steel pipe 1 and the lumps of wood 6 will lay control point according to construction requirement in a pre-installation outside, and exterior sheathing processing and installation must be surveyed the control point of establishing according to scene and be constructed.Before laying exterior sheathing, absolute altitude etc. is checked.
(2) strict control section size and ceiling height, thickness when installing exterior sheathing, to take, the effective measures such as top controls the dislocation of internal mold both sides, distortion, and construction error controls within the scope of allowing in specification.The error that the factors such as stent secondary distortion cause is considered in high process control.Note built-in fitting and hole to be provided.
(3) must be firmly firm when model sheetinstallat is reinforced, seam is tight, must not spillage; Fastening to pull bar.Adopt two-sided tape to close between template, firm during in-site installation, plate stitches closely connected smooth.
(4) prefabricated curved steel tube 4 must be integral prefabricated, and carefully check whether the prefabricated circular arc steel pipe of marching into the arena has crackle or breakage.
(5) as connected with fastener 9, fastener 9 must be connected firmly, and conscientiously should check whether fastener 9 has breakage after precompressed terminates, if any the timely reinforcement of damage.
(6) bamboo slab rubber 7 is processed and is adopted (high rotating speed) alloy saw blade, notes preventing burr during sawing; Shaping template will be avoided exposing to the sun and rain as far as possible, and makes regular check on.
