Abstract

The utility model discloses a positioning wheel disc for straight inserting self-locking scaffoldings, which overcomes defects of general scaffolding positioning devices of low connection rigidity, low stability and existence of safety risks. The wheel disc is a disc as a whole, the inner hole of the disc is round, and the size of the disc is corresponding to the outer profile of the cross section of the vertical pole of the scaffolding. The four plug connecting ports are spaced with an interval of 90 degrees, the inner sides of the ports are communicated, and the outer sides are shaped into a rising slope from the bottom to the top. The sector webs are evenly distributed between adjacent plug connection ports and extended to the margin of the wheel disc to form an arch notch, and the arch is inscribed. The adjacent arch notches are connected in a way of fluid connection to form four parabolic outer ends along the direction of plug connection ports, and the margin of adjacent outer ends is provided with convex ribs circumferentially closed. The utility model not only effectively saves movable parts, but also reduces production cost, increases anti-pressure strength and improves assembling speed.

Description

A kind of location wheel disc of direct insertion self-locking scaffold

Technical field

The utility model relates generally to a kind of direct insertion self-locking scaffold positioner, specially refers to the improvement of vertical rod location wheel disc.

Background technology

Scaffold is widely used in industries such as civil construction project, bridge construction as the indispensable aid of a kind of builing industry, also can be used in shipbuilding industry, decorative craft, stage and builds in the engineerings such as engineering, goods and materials storage and army's march, rescue and relief work.

In the practice of construction operation process, adopt fastener type steel pipe scaffold and bowl fastening type steel pipe scaffold two major types mostly at present, above-mentioned two kinds of steel pipe scaffolds have advantages such as multifunctionality.But being in aspects such as its design principle, geometry, material selection and manufacturing process, user mode mechanics principle remains in many weak points, for example build, speed of application is slower when dismantling, low in conjunction with rigidity, not only there is potential safety hazard in stable deficiency etc., more can influences programming.Become today of market economic development main flow in " reputation of abide bing the contract, keep one's word ", more can bring many inconvenience for unit in charge of construction.

There have been some direct insertion steel pipe scaffolds to come into operation at present, though such scaffold has effectively removed movable members, and improved speed of application, but still having problems aspect contact positioning principle, foundry goods geometry design, the manufacturing process, can not satisfy the needs of the building engineering construction that up-to-dateness improves day by day.Urgent need on the geometry of design principle, node element, auto-lock function improves and to carry out significant improvement, so that reach the purpose of the geometry design of improving direct insertion steel pipe scaffold Positioning Principle design and node element, thereby can reduce production costs, and reliability, the safety of further improving the quality of products and using.

Summary of the invention

The utility model is primarily aimed at the improvement of vertical rod locating wheel dish in the direct insertion self-locking scaffold, it is low in conjunction with rigidity to have solved in the prior art positioner, stability is not enough, there are shortcomings such as potential safety hazard, provide a kind of shaped design reasonable, the compressive strength height, stability in use is good, the location wheel disc that cost of production is low.

The location wheel disc of a kind of direct insertion self-locking scaffold in the utility model, comprise endoporus, plug connector, arc notch, fan-shaped former, outer end points, fan shape hole, protuberance muscle, integral body is disk-like structure, and endoporus is circular, and size is corresponding with the outline of the cross section of vertical rod; Totally four of plug connectors are separated with an angle of 90 degrees mutually, and the plug connector is the U type, and the inboard is communicated with endoporus, and lateral surface is the rising ramped shaped from top to down; Fan type former is distributed between the adjacent plug connector, and extends to wheel plate edge formation arc notch, and arc is the inscribe arcuation; Adopt fluid connected mode correspondence end points outside plug connector direction forms four parabolic shapes between the adjacent arcs v notch v, on the edge between the adjacent outer end points, have the protuberance muscle that seals along circumferentially.

As preferably, endoporus is shaped as circle, and size is corresponding with the outline of the cross section of vertical rod, is sleeved in the vertical rod, and is fixed on by welding manner on the relevant position of vertical rod.

As preferably, described scallop hole is on the fan-shaped arc plate between endoporus and the arc notch, and it is parallel that outer camber line and arc notch edge line match, and it is parallel that interior camber line and endoporus edge line match, and two sidelines are parallel with adjacent header connector sideline respectively.

Fig. 2 is user mode figure of the present utility model.

The specific embodiment

Be better improvements of the present utility model, existing its concrete performance that further specifies in conjunction with the accompanying drawings of embodying.

The location wheel disc of a kind of direct insertion self-locking scaffold in the utility model comprises technology elements compositions such as endoporus 1, plug connector 2, arc notch 3, fan-shaped former 4, outer end points 5, fan shape hole 6, protuberance muscle 7, and integral body is disk-like structure.

In the location wheel disc of a kind of direct insertion self-locking scaffold that the utility model provides, endoporus 1 is shaped as circle, size is corresponding with the outline of the cross section of vertical rod 8, is sleeved on usually in the vertical rod 8, and can be fixed on the relevant position of vertical rod 8 by welding manner.

The location wheel disc of a kind of direct insertion self-locking scaffold that the utility model provides also comprises four mutually with the separated plug connector 2 of an angle of 90 degrees.Plug connector 2 is the U type, and the inboard is communicated with endoporus 1, and lateral surface is the rising ramped shaped from top to down, so that the installation and removal of the wedge-like portion 9 of attachment plug.

Fan-shaped former 4 has four, is distributed between adjacent plug connector 2, and extends to wheel plate edge formation arc notch 3, and arc is the inscribe arcuation.Scallop hole 6 is on the fan-shaped arc plate 4 between endoporus 1 and the arc notch 3, outer camber line matches parallel with arc notch 3 edge lines, interior camber line matches parallel with endoporus 1 edge line, article two, the sideline is parallel with adjacent header connector 2 sidelines respectively, it is stressed evenly to guarantee that in actual job the vertical rod locating wheel is checked and regulated body, and strengthens edge hardness.

Adopt fluid connected mode correspondence end points 5 outside plug connector 2 directions form four parabolic shapes between the adjacent arcs v notch v 3.On the edge between the adjacent outer end points 5, has the protuberance muscle 7 that seals along circumferentially, to strengthen whole bearing strength.

Above-mentioned performance only is preferred embodiment of the present utility model, if any other analogues, when based on claims record scope.
