Description

A kind of stable type scaffold

Technical field

The utility model is related to technical field of building construction more particularly to a kind of stable type scaffolds.

Background technology

Scaffold refers to construction site for convenience of the various branch that worker's working at height solves vertically and horizontally to transport and sets up Frame is generally used for construction and decoration or construction site construction, can stack and transport a certain number of construction materials, and ensure to construct Safety of the personnel in high-altitude application.

The scaffold of the prior art as shown in Figure 1, including holder 1, connecting rod 2 and foot pedal 3, holder 1 are structure phase With two groups, including two vertical upright bars 11 and the cross bar 12 that is fixedly connected between two vertical upright bars 11, cross bar 12 It further include the cat ladder 13 about 12 center symmetric setting of cross bar in 11 upper end of upright bar close to 11 top position of upright bar, on holder 1；Even Bar 2 is four, and cross match is mounted on two pack supports 1 two-by-two, and foot pedal 3, which is taken, to be placed on two cross bars 12, is stood for worker And stacked items.The scaffolding structure of the prior art is simple, easy for installation, can solve the problems, such as worker's working at height.

But in practical applications, this scaffold there are problems that being not sufficiently stable, when the article placed on foot pedal is stacked When uneven or overweight, scaffold is easy imbalance, and when construction site is unstable, scaffold can also incline because of discontinuity Ramp down collapses or needs manually to help, and can also be shaken because of human factor when manually helping, and the safety of staff cannot ensure, Also waste of manpower simultaneously.

Utility model content

The purpose of this utility model is to provide a kind of stable type scaffold, has the characteristics that safety and stability.

The above-mentioned technical purpose of the utility model technical scheme is that：

A kind of stable type scaffold, including two pack supports and the foot pedal that is arranged between two pack supports, are propped up described in every group Frame respectively includes two vertical upright bars, and the sliding component slided up and down along upright bar is arranged in the upright bar, and the sliding component is logical It crosses fixing piece to be locked in upright bar, is rotated on the sliding component and be provided with several supporting rods, the supporting rod is around upright bar array Distribution.

By using above-mentioned technical proposal, the supports of four groups of supporting bar structures enable scaffold it is more firm be placed on ground On face, when the article on foot pedal is overweight, supporting bar structure can help upright bar to share suffered pressure；When construction site When the out-of-flatness of ground, by the angle of the rotation adjustment supporting bar structure of the sliding up and down and supporting rod of sliding component, fixing piece will The sliding component for adjusting good position is fixed in upright bar, is ensured the balance of scaffold with this, can be improved the safety that scaffold uses Property.

Further, flexural pivot joint chair is provided on the sliding component, the supporting rod is rotatably connected on by flexural pivot joint chair On the sliding component.

By using above-mentioned technical proposal, ball-joint can bear larger pulling force and impact force, and reliability is high, be suitble to each It is used under kind varying environment, supporting rod is rotatably installed in sliding component lower face using ball-joint structure, supporting rod can be arbitrary Angular turn is more convenient the use of supporting rod.

Further, the quantity of the supporting rod is 3-5 roots on each sliding component.

By using above-mentioned technical proposal, supporting rod forms triangular structure with upright bar, and stability is best, the number of supporting rod Amount is 3-5 roots, can not only ensure between supporting bar structure or form stable triangular structure, but also will not be because of supporting rod quantity Excessively supporting bar structure is made to complicate, influences the adjustment and use of supporting bar structure.

Further, the supporting rod is telescopic rod.

By using above-mentioned technical proposal, when construction ground out-of-flatness, by manual stretch support bar, each is adjusted The length of strut can coordinate the stabilization and balance for ensureing scaffold.

Further, the supporting rod bottom is arranged with non-slip mat.

By using above-mentioned technical proposal, when construction site ground is smooth, non-slip mat can increase between ground Frictional force prevents supporting rod from sliding the stabilization and balance for influencing scaffold in smooth surface, meanwhile, non-slip mat can be protected smooth Ground prevents supporting rod from scratching ground；When construction site ground is rough whole, non-slip mat plays protection supporting rod bottom Effect.

Further, the upright bar lower end is installed with locating piece close to the position of bottom, on the locating piece with ball Hinged seat opposite position offers the location hole for inserting supporting rod.

Supporting bar structure is closed up when supporting rod need not be used by using above-mentioned technical proposal, by pushing up Dynamic sliding component, each supporting rod is inserted respectively into the location hole of corresponding position, supporting rod can be effectively collapsed, make supporting rod The normal work of scaffold is not interfered with；Locating piece is mounted on upright bar lower end close to bottom position, supporting rod need not be lifted It is too high can by supporting rod be inserted into location hole in, use is efficient and convenient.

Further, the bottom of upright rod is equipped with universal wheel, and the universal wheel is equipped with self-locking device.

By using above-mentioned technical proposal, universal wheel is installed in bottom of upright rod, scaffold is facilitated to move in use, Universal wheel can 360 ° of rotations, such as barrier during movable Scaffold, using universal wheel can flexible rotating bypass hinder Hinder object, facilitates the movement of scaffold；Self-locking device on universal wheel can lock universal wheel when working using scaffold, make ten thousand It cannot be rotated to wheel, ensure the stability of scaffold with this, because scaffold is unexpected when preventing the staff on scaffold from working It moves and accident occurs, ensure the safety of staff.

Further, it is equipped with hand steered cat ladder among at least one set of holder.

By using above-mentioned technical proposal, hand steered cat ladder is arranged in centre, and staff is facilitated to climb on foot pedal, can It is to empty the case where structure may be such that staff makes a misstep, hand steered cat ladder top two to avoid cat ladder that the upright bar both sides at both sides are arranged The cross bar of side can grab drawing for staff, facilitate climbing and ensure safety.

Further, it is twined equipped with rubber ring on the hand steered cat ladder.

By using above-mentioned technical proposal, twined on hand steered cat ladder set rubber ring can increase staff's sole with it is hand steered The frictional force of cat ladder, steps on cunning when preventing staff from climbing, reduce staff presses against feel feel, preferably ensures staff Safety when in climbing to foot pedal.

In conclusion the utility model has the advantages that：

1, the stability of scaffold can be improved by supporting bar structure, adjustable supporting bar structure can also meet foot hand Frame uses in the case of out-of-flatness on construction ground, ensure that the safety of staff, improves the utilization rate of scaffold；

2, by the self-locking device on universal wheel and universal wheel, the mobile use of scaffold can be realized, and can be with It is dynamic with stopping, improve the stability of scaffold, ensure the safety of staff；

3, intermediate hand steered cat ladder structure can facilitate in staff's climbing to foot pedal, improve staff and climbed Safety in journey.
