Abstract

The utility model provides an olecranon clip used for the fixed connection of the crossed rods of a false work. The olecranon clip is provided with a screw rod and a plate clipping axle which are connected in T shape. The screw rod is collocated with an eared nut, the plate clipping axle is hinged with two divided clipping plates having a bayonet and a clipping rod which are matched, and the outer sides of the two divided clipping plates are arranged with two wing clipping plates in splaying shape. The two divided clipping plates can be arranged into scalar form bayonet clipping plates, square bayonet clipping plates and circular bayonet clipping plates in order to be clipped and matched with the connecting rods of a scalar form pipe, a square pipe and a circular pipe. The utility model adopts the olecranon type clutching mode and the locking mode that the screw rod passes through the eared nut for connecting and fixing the two crossed rods. The olecranon clip has the characteristics of correspondingly low production cost for clipping element, convenient installation and operation, labor saving, time saving, stable and reliable connection between rod elements, etc.

Description

Olecranon clip

Technical field

The utility model relates to the connection between the scaffold member, is that a kind of scaffold that is used for intersects the fixedly connected Olecranon clip of rod member.

Background technology

At present the building trade scaffold intersects the fixedly connected of rod member, generally adopts cruciform fastening for falsework through bolton, and it is whenever fixed a bar and need screw nut for twice by the instrument of spanner and so on and can finish.Have troublesome poeration, waste time and energy and fix not firm problem, and the producing cost of fastener is also higher relatively, is unfavorable for reducing the engineering construction cost.

Summary of the invention

The purpose of this utility model is at the problems referred to above, provides a kind of scaffold that is applicable to intersect the connection of rod member, and producing cost is relatively low, and fitting operation is convenient, and time saving and energy saving, rod member interconnects reliable and stable Olecranon clip.

The technical scheme that realizes above-mentioned purpose is: a kind of scaffold that is used for intersects the Olecranon clip that rod member connects, it has the screw rod and the clamp axle of T-shaped connection, on screw rod, dispose wing nut, being hinged on the clamp axle is connected to bayonet socket and two pairs of branch clamps that coincide by kelly, is splayed in the outside of two pairs of branch clamps and is symmetrically arranged with the both wings clamp.

The technical solution of the utility model also comprises: described screw rod and clamp axle are hinged; Tail end at the both wings clamp is provided with the identical arc groove of kelly; On screw rod, be coated with nut collar with the wing nut configuration; Its two pairs of branch clamps are arranged to trapezoidal bayonet socket clamp, square bayonet socket clamp or circular bayonet socket clamp.

The horizontal rod member that the utility model adopts the interlock method of olecranon formula to fix firmly fixes, and the mode that installs wing nut locking by screw rod is fixed on perpendicular putting on the rod member with fastener, and finishes the connection between two rod members.Because of the screwing and unscrew and need not tool using of wing nut, directly promptly dismantled and assembled with hand, and just can finish connection work by once screwing nut, operation is both convenient, time saving and energy saving again; And, make the rod member that is held fixed owing to utilized the reinforcement structure of two wing plates during bayonet socket chucking rod member, improved the reliability that connects between rod member; Because fastener has reduced by a clasp with respect to cross cramp on making, make cost reduce half, so cost of production is low again, helps reducing construction cost.

The specific embodiment

In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.

Provide as accompanying drawing, this Olecranon clip has T-shaped screw rod that links together 1 and clamp axle 2, its screw rod 1 can adopt welding manner to fixedly connected with clamp axle 2, during concrete enforcement preferably the front end at screw rod 1 connecting ring is set and, is beneficial to increase the be installed flexibility of operation and the stable coordination of fixing rod member by connecting ring being sleeved on the mode that is hinged that constitutes on the clamp axle.On screw rod 1, be equipped with wing nut 5, be used for the locking after screw rod penetrates the perpendicular connecting rod of putting, during concrete enforcement, can be on screw rod the nut collar 6 of assembling and wing nut and connecting rod configuration, with stability that increases nut fixing connecting rod and the flexibility that nut screwed and unscrewed operation.Being hinged on clamp axle 2 is connected to bayonet socket and two pairs of branch clamps 3 that matched by kelly, and it is concrete is hinged structure and can hinge eyes be set by the rear end at each clamp, and the clamp axle is threaded onto in the hinge eyes constitutes.Be splayed in the outside of two pairs of branch clamps 3 and be symmetrically arranged with both wings clamp 4, its clamp 4 can adopt the triangle steel sheet metal forming that is the acute angle bending, on being weldingly fixed on, and utilize the edges of boards formation reinforcing rib structure that curves inwardly at two in order to improve its rigidity to minute clamp.

Provide as accompanying drawing 2, this Olecranon clip can be provided with arc groove 7 at the tail end of both wings clamp 4, is used for increasing when assembling with the pipe connecting rod stability that it cooperates.

Provide as accompanying drawing 1, accompanying drawing 3 and accompanying drawing 4, two pairs of branch clamps 3 of this Olecranon clip can be arranged to trapezoidal bayonet socket clamp, square bayonet socket clamp and circular bayonet socket clamp, cooperate to fix with laddertron connecting rod, box section connecting rod and round tube connecting rod respectively.
