Abstract
The utility model discloses an adjustable length just increases fricative scaffold cross rod. It is including the thick round sleeve and thin round sleeve, fastening bolt, snap close piece that have the cusp screw thread, thick round sleeve's the thin round sleeve's of diameter ratio diameter is 4 centimetres big, and thin round sleeve can stretch into thick round sleeve's inside, and two kinds of sleeve surface have the cusp screw thread, the convenient flexible frictional force that increases simultaneously, and two bolt holes are located to be equipped with for 5 centimetres apart from the edge by thick round sleeve right -hand member to being equipped with and consolidating the use, thick round sleeve left end edge welds with ordinary snap close piece respectively with thin round sleeve right -hand member edge, and convenient and current scaffold frame montant is connected. The utility model overcomes cusp screw sleeve can effectively be utilized to current scaffold cross rod's shortcoming, and increase frictional force is convenient flexible, has improved the flexibility and the security of scaffold frame.
Description
Technical field
This utility model is related to scaffold field, more particularly to a kind of adjustable length and and can increase the foot of friction
Hand cradle cross bar.
Background technology
With the development of society, the application of scaffold is more and more extensive, in the work progress of house, tunnel and water tower etc.
In relate to, the safety of scaffold cross bar becomes therewith an important problem with convenience.Traditional scaffold cross bar base
This is smooth circular casing, and length can not change, and sets up inconvenience and friction is little, and safety coefficient is relatively low.
The content of the invention
This utility model provides a kind of simple structure exactly in order to solve above-mentioned technical problem, can be according to site operation
Situation adjustment length simultaneously can improve frictional force, reduce the scaffold cross bar of construction cost.
To solve above-mentioned technical problem, what this utility model was achieved through the following technical solutions：
Adjustable length and increase friction scaffold cross bar, including with toothed thread circular sleeve, fastening bolt,
Snap close piece, fastening bolt is tightened in prepared screw-bolt hole of the thick circular sleeve right-hand member away from the centimeters of edge 5, and snap close piece is welded on slightly
Circular sleeve left end edge and thin circular sleeve right-hand member edge.
On the one hand the toothed thread on circular sleeve surface can be such that thick circular sleeve and thin circular sleeve is closely connected to become
One entirety, on the other hand can increase the friction for laying the objects such as plate with beam contact, and anti-sliding stop effectively improves safety
Property.
Thick circular sleeve left end edge and thin circular sleeve right-hand member edge are welded respectively with common snap close piece, prevent snap close piece
Convenient and existing common montant is assembled while loss, to improve site operation efficiency.
The beneficial effects of the utility model are：This utility model adopts two-part circle dentation screw shell, using dentation
The friction and occlusion of screw thread can be such that scaffold cross bar conveniently quickly connects as the case may be, and the surface of sleeve
Because of toothed thread, increase and the friction for laying the objects such as plate, with anti-skidding effect, improve safety during construction
Property, thick circular sleeve left end edge and thin circular sleeve right-hand member edge weld respectively with common snap close piece, prevents snap close piece from losing
Again convenient and existing scaffold montant Assembling, improves efficiency.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is combination scheme of installation of the present utility model.
Reference：The thick circular sleeve of 1- dentations；The thin circular sleeve of 2- dentations；3- fastening bolts；4- fastening bolts；5- is thick
The inner surface bottom toothed thread of circular sleeve；The outer surface bottom toothed thread of the thin circular sleeves of 6-；The thick circular sleeves of 7-
Outer surface top screw thread；The outer surface top screw thread of the thin circular sleeves of 8-；The snap close piece that 9- is welded with thick circular sleeve；10- with
The snap close piece of thin circular sleeve welding.
Specific embodiment
With reference to shown in Fig. 1, adjustable length and increase the scaffold cross bar of friction and have the thick circular sleeve 1 of dentation, it upper
There is toothed thread in the surfaces externally and internally and lower inner surface in portion, thereon surface is reserved with bolt hole 3 and 4；Dentation is carefully circular
There is toothed thread in the outer surface of the upper and lower of sleeve 2, the convenient and thick circular sleeve 1 of dentation closely connects and increases outside
Frictional force, fastening bolt 3 and 4 makes the connection of the thick circular sleeve 1 of dentation and the thin circular sleeve 2 of dentation more firm, prevents relative
Slide, snap close piece 9 and 10 causes sleeve to be connected convenient with scaffold montant.
With reference to shown in Fig. 2, when installing at the scene, thin circular sleeve 2 is put into the inside of thick circular sleeve 1, according to concrete
Regulating working conditions tighten fastening bolt 3 and 4 to after appropriate length, toothed thread 5 and 6 is closely engaged, it is ensured that sleeve 1 and 2 can
An entirety is firmly connected to become, then snap close piece 9 and 10 is attached with common scaffold montant, installed.
