Description
[technical field]
The present invention relates to the building operations apparatus, particularly relate to the linkage of a kind of building scaffold and bearing frame.
[background technology]
Must scaffold erecting and bearing frame in the architecture construction.Existing scaffold, bearing frame mostly are steel tube fastener formula scaffold, bowl button frame, door type frame etc.Steel tube fastener formula scaffold building is flexible, and compliance is strong, and globality is better, but its computation model and sketch and actual conditions gap are bigger when designing and calculating.This is that each rod member meets at a bit because the node of computation model and sketch is hinged, but during actual setting up, reason owing to fastener self, various rod members can not meet at a bit, and can produce up to the eccentric throw about 53mm, cause the big potential safety hazard of scaffold global existence.The security incident of caving in regard to recurrent steel tube fastener formula scaffold and bearing frame, the checkout result of support body design and actual loading situation are inconsistent to be the major reason that similar accident produces, and because all kinds of fastener enormous amount that steel tube fastener formula scaffold and bearing frame are disposed are lost in the construction and well damage.Engineering with a term is an example, and loss is about about 30%.Bowl button frame, door type frame can remedy steel tube fastener formula scaffold and the bearing frame defective on stressed, but its specificity is too strong, will dispose the support of different moduluses to different engineerings, and it is too high to cause enterprise to drop into aspect support.
The present invention is intended to address the above problem, and provides a kind of mechanical property good, sets up simple and efficiently, safe in utilization, can effectively reduce construction cost, the building scaffold that is easy to apply and the linkage of bearing frame.
For achieving the above object, the invention provides the linkage of a kind of building scaffold and bearing frame, this linkage comprises that this linkage comprises a plurality of cross-connects and a plurality of antiskid connector, described a plurality of cross-connect is pressed first front rail and first rear transverse rod that the scaffold width is provided with a plurality of two of affixed one-tenth of hyphen bars difference, each cross-connect is at first front rail and the first rear transverse rod opposite side and be located at first front rail, a plurality of second cross bars between first rear transverse rod are connected, each cross-connect vertically then is being connected with a plurality of montants by a plurality of antiskid connectors, and each antiskid connector is located at respectively between each cross-connect and each montant.
Cross bar, second cross bar and montant are steel pipe.
Cross-connect comprises vertical adapter sleeve, two screw rods and horizontal adapter sleeve, wherein, described vertical adapter sleeve in a tubular form and upper and lower uncovered, its body outside radially is connected with two screw rods symmetrically, one of them screw rod is threaded by horizontal adapter sleeve with the hyphen bar, another screw rod is threaded with the hyphen bar, and vertical adapter sleeve is affixed at a side and second cross bar perpendicular to two screw rods; One end of described horizontal adapter sleeve is uncovered, be provided with one section internal thread at this opening end, laterally the other end of adapter sleeve is provided with end cap, laterally the opening end of adapter sleeve is connected with the screw flight of cross-connect, the other end of horizontal adapter sleeve is that the pull bar of T shape is connected with the hyphen bar by the cross section, one end of this pull bar places in the horizontal adapter sleeve versatilely, and the other end passes the end cap of horizontal adapter sleeve and affixed with the hyphen bar.
The internal diameter of vertical adapter sleeve is slightly larger than the external diameter of montant.
Two screw rods are made into integration with vertical adapter sleeve, or fixing with vertical adapter sleeve welding.
The two ends of each second cross bar are affixed and form one with cross-connect respectively.
The antiskid connector is made of the up-small and down-big left tapered sleeve and the right tapered sleeve that when the non-working condition are separation member, and wherein, the link end of left tapered sleeve is provided with two projections that extend to the front side; The link end of right tapered sleeve is provided with two grooves that insert for described projection; The antiskid connector is one with left tapered sleeve and right tapered sleeve in the connecting portion involutory grafting in the outside of montant in use, forms wedge shape antiskid connector, and described cross-connect is sheathed on the outside of antiskid connector.
On the inwall of left tapered sleeve and right tapered sleeve, respectively be provided with muscle at least one convex anti-skidding.
Joint portion with cross-connect on montant is provided with reinforcing sleeve, and this reinforcing sleeve and montant welding are fixing.
Contribution of the present invention is that it has effectively overcome all drawbacks of existing building scaffold and bearing frame, and has following distinguishing feature:
One, all rod members of this device all meet at a bit when setting up, and the actual loading situation conforms to sketch fully with calculation model for design, and stress point is clear and definite, and is error free.Test shows, resistance to compression, bending resistance, shearing resistance, the antiskid at the node place of this device moves many indexs such as bearing capacity and all is better than existing other various connected modes, therefore improve intensity, integral rigidity and the stability of scaffold and bearing frame, guaranteed the use completeness of scaffold and bearing frame.
Two, set up easy, quick, safety.Because in the device of the present invention, cross-connect and rod member are connected as a single entity, needing the node of artificial connection at the construction field (site) only be about 1/10th of other connected mode, thereby taking of scaffold tear open more simple and efficiently, and work efficiency can improve more than three times.Significantly reduce because of loose mail simultaneously, make scaffold take the also significantly minimizing of accident of falling from the high-altitude and causing because of loose mail when tearing open, therefore guaranteed construction safety.
Three, cost significantly reduces, and is easy to apply.Because in the device of the present invention, cross-connect and rod member are connected as a single entity, thereby be convenient to keeping and transportation, be difficult in the construction losing and damaging, needing in traditional connected mode to have avoided the defective of repeated configuration fastener, thereby can significantly reduce integrated cost.The present invention also can transform and utilizes employed steel pipe in the scaffold that otherwise connects, and it is reusable to transform the back.Because this apparatus structure is simple, set up easyly, quick, safe in utilization, therefore be easy to apply.
