Description
Technical field
The utility model relates to building operations steel pipe support technical field, particularly its cover dish structure, the vertical rod of building formwork steel pipe support, adjustable vertical rod, movable sleeve pan arrest seat and a building mode structure.
Background technology
At present, in the use in building operations steel pipe support field, being connected between vertical rod and the cross bar, the following two kinds of structures of most of employing, 1) fastener type steel pipe support: 2) grafting type dish button steel pipe support, these two kinds of structures can efflux uses such as grid are set up, template support.
In above-mentioned two kinds of constructed products are used, mainly there is following technological deficiency: 1) for the fastener type steel pipe support, it need be twisted by bolt and connect, it is loaded down with trivial details that connection is installed, and because these fasteners are cast member, when cast member has sand holes, can not get rid of the serious consequence that stressed back explosion occurs, thereby unserviceable situation occur.In addition, this fastener type steel pipe support is because its complicated structure, its lateral deformation stiffness and bearing capacity can't further improve, simultaneously, increase along with load, the rigidity of fastener type support is degenerated comparatively fast, lateral deformation stiffness diminishes, the permanent set maximum, and therefore, this structure can't further be satisfied with the needs of current safety in production well.2) for grafting type dish button steel pipe support, its dish buckle structure is the flat pattern structure, be welded on the steel pipe, its thickness in vertical direction generally has only 5-10mm, can only bear the pressure of 10-30KN, weight bearing power is relatively poor, when in the through hole of dish button, inserting the cross bar plug, when bearing bigger pressure, the cover dish is bending distortion downwards easily, and the building formwork product weight bearing power of composition is relatively poor, therefore, the dish of grafting type dish button steel pipe support is buckled and can not directly be used as the load supporting, but the load steel pipe is placed in the U-shaped pop-up that the grafting type dish button steel pipe support on the top arranges, and sets up thereby constitute building the common of formwork, mounts imitative wood at the load steel pipe, and need the more imitative wood of discharging, could support prop up template.Equally, in the fastener type steel pipe support, also there is corresponding technical problem.
In sum, the steel pipe support structure that existing formwork system adopts can't satisfy the needs that security performance is reliable, save resource, install and remove fast, how to develop a kind of both safe and reliablely, the steel pipe support product that is simple and easy to usefulness has again become an important topic of building operations aspect.
In addition, the applicant is in the patent documentation of application in the early time, a kind of scaffold product that adopts connected structure is arranged, it has some improvement at aspect of performance as the steel pipe support structure, but its button dish is cast structure, occurs easily causing situation about rupturing because of sand holes, therefore, still can't be advantageously applied in the formwork system.

The manufacture craft of the cover dish structure of building operations shell type steel pipe support may further comprise the steps:
1), die-cut material, hot rolled plate is placed on the blank that stamps out strip on the punch press;
2), punch forming, the blank of gained in the step 1) is placed on the punch press, by moulding form is processed into semiproduct, described semiproduct comprise vertical arch framework and can be spliced into the facade of vertical arch framework then;
3), the welding, two stamping forming semiproduct neatly are stitched together, and then they are welded into a complete cover dish.
Further, when described step 2) blank being struck out semiproduct, needed sealing weld breach 102 and as the protrusion 101 of pointing 103 when processing welding cover dish at the two ends of blank by moulding form, the breadth-first of the widest part of above-mentioned sealing weld breach 102 is processed as 1.6mm, and the thickness of described protrusion 101 preferentially is processed as 2.3mm.
Further again, before carrying out the described welding of step 3), two semiproduct after punch forming need be carried out the school type handles, make two ends, half-finished left and right sides be on the same level, thereby make two half-finished when being spliced into a cover dish of finishing mutually, splicing mouth between the two is more smooth, convenient welding.
Further, the cover dish of welding gained need be placed on and carry out the shaping processing on the punch press in the described step 3), revise the micro-strain that the cover dish forms in welding process, and then the cover dish after the shaping processing is tested, prevent the incomplete cover dish of Lou shaping or shaping.
Preferential employing thickness of slab is the hot rolled plate of 3-10mm in the described step 1), and it is die-cut into the blank that width is 30-38mm, and then blank struck out semiproduct, its facade thickness in vertical direction of described semiproduct is 30-38mm, when the welding of two semiproduct is spliced into a complete cover dish, preferential employing argon arc welding melts the protrusion 101 on two semiproduct as pointing 103, by pointing 103 the sealing weld breach 102 between two semiproduct is filled up, because the material of protrusion 101 is identical with half-finished material, therefore with the pointing 103 of protrusion 101 as filling sealing weld breach 102, can make that the welding between two semiproduct is more firm, strengthened the weld strength of cover dish widely, when guaranteeing that the cover dish bears bigger pressure, two semiproduct can not separate.
The plug that above-mentioned and cover coil parts such as load keel that mutual eye-splice is connected, steel pipe support horizontal cross bar, the horizontal vertical pole of steel pipe support is metal plate punching spare.
The above only is preferential embodiment of the present utility model, as long as realize that with basic identical means the technical scheme of the utility model purpose all belongs within the protection domain of the present utility model.
