Description
Technical field
The invention discloses a kind of quick detach scaffold, particularly a kind of spigot-and-socket quick detach scaffold.
Background technology
The scaffold of current building site has a variety of, wherein ring-type key connecting pin hand cradle and the rim of a bowl formula scaffold more common, the vertical rod of these non-spigot-and-socket scaffolds is stressed is eccentric force, and the eccentric force of vertical rod causes the stability of scaffold not good, and application life shortens.
Patent 2011100233221.7 discloses a kind of scaffold, and montant is connected with flange, and flange is provided with socket, and cross bar link is provided with the latch matched.Its shortcoming is, first, latch, after insertion socket, because spigot does not retrain, easily causes cross bar to connect built on the sand, offsets.
Summary of the invention
The invention is intended to provide a kind of axially loaded, stability high, load and unload quick detach scaffold flexibly.
Object of the present invention can be reached by following measures: a kind of quick detach scaffold, comprise vertical rod and cross bar, vertical rod is divided into upper and lower vertical rod, also comprise connector, connector is made up of upper end, lower end, stage casing, the upper and lower end of connector inserts respectively in upper and lower vertical rod and is connected and fixed, and the external diameter in connector stage casing is greater than vertical rod external diameter, and stage casing is provided with dop; Described cross bar link is cecum, and cecum is provided with the bayonet socket coordinated with dop; Described upper pright stanchion is also provided with the lock piece preventing cross bar prolapse upwards.
Technique scheme difference with the prior art is: first, cross bar is fixed in vertical rod by connector, the load of cross bar passes to connector by dop, because connector two ends are inserted in upper and lower vertical rod respectively, during connector pressurized, load is passed to lower vertical rod vertically, avoid vertical rod and cause because of eccentric force scaffold unstable; Secondly, upper and lower vertical rod is connected by connector, forms connected node, decreases the slenderness ratio of upper and lower vertical rod, enhance the stability of quick detach scaffold; Again, bayonet socket is set at cross bar cecum, after dop inserts, forms horizontal restraint, avoid the displacement of cross bar occurred level; Again, upper pright stanchion arranges lock piece, can prevent cross bar from upwards deviating from bayonet socket.
Further, described lock piece comprises the fixing spacing ring in upper pright stanchion surface, and inwall, with the sleeve pipe of projection, described spacing ring has the breach that projection passes through; Its lower end can prop up cross bar, prevents cross bar prolapse upwards bayonet socket, and by revoling tube, projection aims at spacing ring breach, and namely sleeve pipe can slide past spacing ring, and revoling tube makes projection and spacing ring breach stagger, and spacing ring can prevent sleeve pipe upward sliding.
Further, described lock piece comprise inwall with groove sleeve pipe, be fixed on the boss at upper pright stanchion place, described sleeve pipe groove can slide past upper pright stanchion boss; Its lower end can prop up on cross bar, prevents cross bar prolapse upwards bayonet socket, and by revoling tube, sleeve pipe groove aims at vertical rod boss, and namely sleeve pipe can slide past vertical rod boss, and revoling tube makes groove and vertical rod boss stagger, and can prevent sleeve pipe upward sliding.
Further, described connector and upper and lower vertical rod plug welding or groove welding, make connector be connected more reliable with upper and lower vertical rod.
Further, described dop is L shape dop, comprises lateral part and vertical part, and the cross section of lateral part is trapezoidal; Cross bar cecum bayonet socket corresponding to described lateral part is that trapezoidal joint face makes the connection of dop and bayonet socket more reliable also for trapezoidal.
Mechanical property of the present invention is good, connection is reliable, the scaffold good integrity of composition, being applicable to set up the construction of civil engineering mechanism and the dual-purpose external scaffolding of fitment operation, can also, as the bracing frame of template and other temporary platform supports etc., be a kind of multi-functional quick detach scaffold.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of quick detach scaffold embodiment 1 of the present invention vertical rod.
Fig. 2 is the structural representation of quick detach scaffold embodiment 1 cross bar of the present invention.
Fig. 3 is the structural representation of quick detach scaffold embodiment 2 of the present invention vertical rod.
Detailed description of the invention
Embodiment 1: with reference to Fig. 1, a kind of quick detach scaffold, comprises upper pright stanchion 1, lower vertical rod 2, cross bar 3 and connector 4.The link of cross bar 3 is sealed by welding steel 31, forms cecum; Cross bar 3 link has bayonet socket 32.
Connector 4 comprises upper end, stage casing and lower end, the external diameter in stage casing is greater than the external diameter of upper pright stanchion 1, lower vertical rod 2, upper end, lower end are inserted in upper pright stanchion 1 and lower vertical rod 2 tube wall respectively, carry out plug welding or groove welding, upper pright stanchion 1, connector 4, lower vertical rod 2 connect into the vertical applied force bar of quick detach scaffold; Connector 4 stage casing is distributed with four dops 41, described dop 41 comprises lateral part and vertical part, and the cross section of described lateral part is trapezoidal, and the cecum bayonet socket 32 of the cross bar 3 that described lateral part is corresponding is also for trapezoidal; Above-mentioned dop 41 inserts bayonet socket 32 internal fixtion, and connector 4 is connected with cross bar 3, then vertical applied force bar is connected with cross bar 3.
Upper pright stanchion 1 has placed sleeve pipe 5, and sleeve pipe 5 inwall is with two relative projections 51, and sleeve pipe 5 can slide up and down at upper pright stanchion 1 place; Be welded with spacing ring 6 at upper pright stanchion 1 near connector 4 place, this spacing ring 6 is the reinforcing bar with two opposed notches, and this breach can pass through for sleeve pipe projection 51, and described sleeve pipe 5 lower end can limit cross bar 3 prolapse upwards bayonet socket 32.During use, by revoling tube 5, projection 51 aims at spacing ring 6 breach, and namely sleeve pipe 5 can slide past spacing ring 6, and revoling tube 5 makes projection 51 and spacing ring 6 breach stagger, then spacing ring 6 can prevent sleeve pipe 5 from upwards skidding off.
Embodiment 2: see Fig. 3, difference from Example 1 is, upper pright stanchion 1 has placed sleeve pipe 5, and sleeve pipe 5 inwall is with two relative grooves 52, and sleeve pipe 5 can slide up and down at upper pright stanchion 1 place; To be welded with two relative boss 7 near connector 4 place at upper pright stanchion 1, the groove 52 of described sleeve pipe 5 can slide past boss 7; All the other features of embodiment 2 are identical with embodiment 1.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
