Description

The quick detach scaffold

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 that present building site is used has a variety of; Wherein ring-type key connection scaffold and the rim of a bowl formula scaffold are more common; The stressed eccentric force that is of the vertical rod of these non-spigot-and-socket scaffolds, the eccentric force of vertical rod cause the stability of scaffold not good, and shorten application life.

Patent 2011100233221.7 discloses a kind of scaffold, is connected with flange on the montant, and flange is provided with socket, and the cross bar link is provided with the latch that is complementary.Its shortcoming is that at first, latch because not constraint of spigot is prone to cause cross bar to connect built on the sand, squints after inserting socket.

Summary of the invention

The invention is intended to provide a kind of axially loaded, stability height, load and unload quick detach scaffold flexibly.

The object of the invention can reach through following measure: a kind of quick detach scaffold; Comprise vertical rod and cross bar, vertical rod is divided into upper and lower vertical rod, also comprises connector; Connector is made up of upper end, lower end, stage casing; The upper and lower end of connector inserts respectively to connect in the upper and lower vertical rod and fixes, and the external diameter in connector stage casing is greater than the vertical rod external diameter, and the stage casing is provided with dop; Said cross bar link is a cecum, and cecum is provided with the bayonet socket that cooperates with dop; Also be provided with the lock piece that prevents that cross bar from making progress and on the said upper pright stanchion.

The technique scheme difference with the prior art is: at first; Cross bar is fixed in the vertical rod through connector; The load of cross bar passes to connector through dop; Because insert respectively in the upper and lower vertical rod at the connector two ends, during the connector pressurized load is passed to down vertical rod vertically, avoided vertical rod to cause scaffold unstable because of eccentric force; Secondly, upper and lower vertical rod connects through connector, forms connected node, has reduced the slenderness ratio of upper and lower vertical rod, has strengthened the stability of quick detach scaffold; Once more, bayonet socket is set, inserts the back at dop and form horizontal restraint, avoided the displacement of cross bar occurred level at the cross bar cecum; Once more, lock piece is set on the upper pright stanchion, can prevents that cross bar from upwards deviating from bayonet socket.

Further, said lock piece comprises the fixing spacing ring in upper pright stanchion surface, and inwall has the sleeve pipe of projection, has the breach that projection passes through on the said spacing ring; The sleeve pipe lower end can prop up cross bar, prevents the cross bar bayonet socket that makes progress, and through revoling tube, projection is aimed at the spacing ring breach, and sleeve pipe can slip over spacing ring, and revoling tube makes projection and spacing ring breach stagger, and spacing ring can prevent upwards slip of sleeve pipe.

Further, said lock piece comprises that inwall has the sleeve pipe of groove, is fixed on the boss at upper pright stanchion place, and said sleeve pipe groove can slip over the upper pright stanchion boss; The sleeve pipe lower end can prop up on cross bar, prevents the cross bar bayonet socket that makes progress, and through revoling tube, the sleeve pipe groove is aimed at the vertical rod boss, and sleeve pipe can slip over the vertical rod boss, and revoling tube makes groove and vertical rod boss stagger, and can prevent upwards slip of sleeve pipe.

Further, said 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, said dop is L shaped dop, comprises lateral part and vertical part, and the cross section of lateral part is trapezoidal; The corresponding cross bar cecum bayonet socket in said lateral part is for also being that trapezoidal, trapezoidal joint face makes dop more reliable with being connected of bayonet socket.

Mechanical property of the present invention is good, connection is reliable; The scaffold good integrity of forming; Being applicable to and setting up civil engineering mechanism construction and the dual-purpose external scaffolding of fitment operation, can also be a kind of multi-functional quick detach scaffold as the bracing frame of template and other temporary platform supports etc.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation:

Fig. 1 is the structural representation of quick detach scaffold embodiment of the present invention 1 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 of the present invention 2 vertical rods.

The specific embodiment

Embodiment 1: with reference to Fig. 1, a kind of quick detach scaffold comprises upper pright stanchion 1, following vertical rod 2, cross bar 3 and connector 4.The link of cross bar 3 seals through welding steel 31, forms cecum; Cross bar 3 links have 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, following vertical rod 2; Insert respectively in upper pright stanchion 1 and following vertical rod 2 tube walls upper end, lower end; Carry out the welding of plug welding or groove, upper pright stanchion 1, connector 4, following vertical rod 2 connect into the vertical applied force bar of quick detach scaffold; Be distributed with four dops 41 on connector 4 stage casings, said dop 41 comprises lateral part and vertical part, and the cross section of said lateral part is trapezoidal, and the cecum bayonet socket 32 of the cross bar 3 that said lateral part is corresponding is for also being trapezoidal; Above-mentioned dop 41 inserts in the bayonet socket 32 fixing, and connector 4 is connected with cross bar 3, and then the vertical applied force bar is connected with cross bar 3.

Upper pright stanchion 1 has placed sleeve pipe 5, and sleeve pipe 5 inwalls have 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 places, this spacing ring 6 is for having the reinforcing bar of two relative breach, and this breach can supply sleeve pipe projection 51 to pass through, and cross bar 3 bayonet socket 32 that makes progress can be limited in said sleeve pipe 5 lower ends.During use, through revoling tube 5, projection 51 is aimed at spacing ring 6 breach, and sleeve pipe 5 can slip over spacing ring 6, and revoling tube 5 makes projection 51 and spacing ring 6 breach stagger, and then spacing ring 6 can prevent that sleeve pipe 5 from upwards skidding off.

Embodiment 2: referring to Fig. 3, be that with embodiment 1 difference upper pright stanchion 1 has placed sleeve pipe 5, sleeve pipe 5 inwalls have two relative grooves 52, and sleeve pipe 5 can slide up and down at upper pright stanchion 1 place; Be welded with two relative boss 7 at upper pright stanchion 1 near connector 4 places, the groove 52 of said sleeve pipe 5 can slip over boss 7; Embodiment 2 all the other characteristics are identical with embodiment 1.

Above-described only is preferred implementation of the present invention; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from structure of the present invention, can also make some distortion and improvement; These also should be regarded as protection scope of the present invention, and these can not influence effect and practical applicability that the present invention implements.
