Abstract
The utility model discloses a kind of scaffold fastenings and aluminium alloy scaffold being cold-pressed for cold expanding, tube expanding joint portion and pressure pipe connecting portion including tubular, wherein, the inwall in the tube expanding joint portion is provided with multiple grooves, and the outer wall of the pressure pipe connecting portion is provided with multiple grooves.Perpendicular aluminum pipe and horizontal aluminum pipe are fixedly connected on by tube expanding joint portion and pressure pipe connecting portion by cold expanding and cold-press process respectively.Because cold expanding cold-press process will not change the molecular structure of aluminum alloy materials, the connected mode is significantly better than common welding procedure and riveting process structure in terms of intensity, stability and durability.
Description
Technical field
The utility model is related to a kind of scaffold fastenings, more particularly to a kind of scaffold connection being cold-pressed for cold expanding
Part, belongs to scaffold fastenings technical field.
Background technology
Scaffold is the various supports built at the construction field (site), mainly for operation above and below workmen or perimeter security net
Go along with sb. to guard him and high-altitude installation component etc., it is general using aluminum alloy materials processing and manufacturing in order to mitigate the weight of scaffold.And it is now several
All aluminum or aluminum alloy products are all the riveting process using welding procedure or simple and mechanical mode, such as door and window, herringbone
Ladder, family expenses aluminum pot etc., aluminum alloy materials can produce internal stress, destructible aluminium interior molecules knot using hot worked welding technique
, easily there is phenomenon of rupture in structure, the reduction original intensity of material and durability；And screw connection, for a long time using life occurs
The problem of rust or stripped thread, the Stability Analysis of Structures to whole scaffold all has a great impact, or even the risk collapsed occurs.
Therefore, prior art has yet to be improved and developed.
The content of the invention
For above-mentioned problems of the prior art, the purpose of this utility model is that providing a kind of cold expanding that is used for is cold-pressed
Scaffold fastenings and aluminium alloy scaffold, it is intended to overcome it is existing welding or riveting process can not meet scaffold intensity requirement
Defect.
The technical solution of the utility model is as follows：A kind of scaffold fastenings being cold-pressed for cold expanding, including tubular are swollen
Pipe jointing part and pressure pipe connecting portion, wherein, the inwall in the tube expanding joint portion is provided with groove, the outer wall of the pressure pipe connecting portion
It is provided with groove.
The scaffold fastenings being cold-pressed for cold expanding, wherein, the end face of the groove is trapezoidal shape.
The scaffold fastenings being cold-pressed for cold expanding, wherein, tube expanding joint portion and pressure pipe connecting portion are " T " font one
Body structure.
The scaffold fastenings being cold-pressed for cold expanding, are made up of aluminum alloy materials.
A kind of aluminium alloy scaffold, wherein, the aluminium alloy scaffold includes horizontal aluminum pipe, erects aluminum pipe and above-mentioned for cold expanding
The scaffold fastenings of cold pressing.
The aluminium alloy scaffold, wherein, the perpendicular aluminum pipe of scaffold coordinates insertion tube expanding joint portion inner chamber, and utilizes
Cold expanding technique clamping, the horizontal aluminum pipe engagement sleeves of scaffold utilize cold-press process clamping in pressure pipe connecting portion periphery.
The beneficial effects of the utility model：The utility model provides a kind of scaffold fastenings, is connected using the connector
When the horizontal aluminum pipe of scaffold is with perpendicular aluminum pipe, perpendicular aluminum pipe and horizontal aluminum pipe are fixedly connected on by tube expansion by cold expanding and cold-press process respectively and connected
Socket part and pressure pipe connecting portion.Because cold expanding cold-press process will not change the molecular structure of aluminum alloy materials, the connected mode is strong
It is significantly better than in terms of degree, stability and durability under common welding procedure and riveting process structure, static test, its intensity surpasses
Cross the three times pulling-out force of welding（Bear pulling force about 6000KG）, the experiment of 250000 times is born under dynamic test and existing without fracture
As.
Brief description of the drawings
Fig. 1 is scaffold fastenings schematic diagram described in the utility model.
Fig. 2 is the schematic diagram that horizontal aluminum pipe and perpendicular aluminum pipe are connected using scaffold fastenings described in the utility model.
Wherein, 1- tube expanding joints portion, 2- pressure pipe connecting portions, 3- grooves, 4- erects aluminum pipe, the horizontal aluminum pipes of 5-.
Embodiment
To make the purpose of this utility model, technical scheme and effect clearer, clear and definite, give an actual example below new to this practicality
Type is further described.It should be appreciated that specific embodiment described herein is only used for explaining the utility model, it is not used to
Limit the utility model.
As shown in figure 1, the present embodiment provides a kind of scaffold fastenings being cold-pressed for cold expanding, including the tube expansion of tubular connects
Socket part 1 and pressure pipe connecting portion 2, wherein, the inwall in the tube expanding joint portion 1 is provided with outside multiple grooves 3, pressure pipe connecting portion 2
Wall is provided with multiple grooves 3.
As shown in Fig. 2 when connecting the horizontal aluminum pipe 5 of scaffold with perpendicular aluminum pipe 4 using connector described in the utility model, by perpendicular aluminium
Pipe 4, which coordinates, to be inserted in the inner chamber in its tube expanding joint portion 1, by inflating cold expanding technique by positioned at the perpendicular aluminium of the inner chamber of tube expanding joint portion 1
Pipe 4 outwards swells, and deforms its inner surface contour along tube expanding joint portion 1, because the inwall in tube expanding joint portion 1 is provided with groove
3, so that perpendicular aluminum pipe 4 is connected with the mutual clamping in tube expanding joint portion 1；The end engagement sleeves of horizontal aluminum pipe 5 are connected in pressure pipe
The periphery of socket part 2, makes outer wall profile compression of the horizontal end of aluminum pipe 5 along pressure pipe connecting portion 2 using cold pressing, due to pressure pipe connection
The outer wall in portion 2 is provided with groove 3, so that horizontal aluminum pipe 5 is connected with the mutual clamping of the outer wall of pressure pipe connecting portion 2, you can complete
Into the connection of horizontal aluminum pipe 5 and perpendicular aluminum pipe 4.Because cold expanding cold-press process will not change the molecular structure of aluminum alloy materials, slightly not
It can reduce, the connected mode is significantly better than common welding procedure and riveting process knot in terms of intensity, stability and durability
Under structure, static test, its intensity exceedes the three times pulling-out force of welding（Bear pulling force about 6000KG）, bear under dynamic test
The experiment of 250000 times and without phenomenon of rupture.
In the present embodiment, the end face of the groove 3 is set to trapezoidal shape.Such shape not only contributes to connection anyhow
