Abstract
The utility model discloses a horizontal diagonal rod for bracing frame or scaffold comprising a rod body and joints which are welded on two sides of the rod body, the length of the rod body ranging from 500mm to 2500mm, the rod body being a round pipe, the thickness of the round pipe wall ranging from 2mm to 3.2mm, preferably, the length of cross bar being 539.7mm, or 839.7mm, or 1139.7mm, or 1439.7mm, or 1739.7mm, or 2339.7mm, the thickness of round tube wall being 2.5mm or 3.05mm, the cross bar adopting galvanizing process. The utility model has the advantages of simple structure, large bearing capacity, standard member, rational weight, steel conservation, and easy installation and transportation.
Description
Technical field
The utility model relates to a kind of bracing frame or scaffold member, especially relates to the horizontal brace of a kind of bracing frame or scaffold.
Background technology
In fields such as building operations, industrial maintenance, theatrical performances and sports tournament activity, the bowl fastening type scaffold of extensive use, steel tube fastener formula scaffold, various plug-in type scaffold and door-type scaffold, exist following several significant problem, be that major casualties takes place frequently, a large amount of waste steel, waste man-hour in a large number, the main cause of wasting freight charges in a large number.The first, obscured the notion of scaffold and bracing frame two series products, mistakenly scaffold has been used as bracing frame.Scaffold is applied to fields such as external wall frame, finishing maintenance, industrial facility maintenance, theatrical performances and sports tournament activity more, the load that is characterized in acting on scaffold is lower, and all act on the whippletree, be transmitted in the vertical rod by node again by scaffold floor.Bracing frame then is mainly used in bridge and the building operations, in the form bracing system of fluid concrete.Be characterized in that the load that acts on bracing frame is higher relatively, and directly acts in the vertical rod of bracing frame.Based on the difference of above-mentioned application, require bracing frame in when design, the ultimate bearing capacity of its vertical rod be far longer than the vertical rod bearing capacity of scaffold, and the bearing capacity of scaffold whippletree needs the bearing capacity greater than bracing frame again.Thereby above-mentioned a few money scaffold from the control of material selection, mechanics design and manufacturing process, all has different greatly with bracing frame when design.Use as bracing frame with these products that are designed to scaffold originally, consequently increase vertical rod quantity in large quantities, thereby increase steel using amount.The consequence of increase system rod member quantity and steel using amount is that the waste steel are wasted and mounted and dismounted man-hour, the waste freight charges.The second, at present a large amount of scaffolds use as supporting, and except above-mentioned first shortcoming, the fastening degree of node has greatly determined the stability of system, and this link is actual uncontrollable, causes huge potential safety hazard.Three, scaffold is widely used in the support system of bridge and building, and except above-mentioned first shortcoming, because design, system lacks reliably, the brace rod member of standard, is the major reason that causes the support system unstability to cave in.
Summary of the invention
The purpose of this utility model provides that a kind of simple in structure, bearing capacity is big, member standard, weight rationally, save steel, be easy to a kind of bracing frame or the horizontal brace of scaffold installing and carry.
The technical solution of the utility model is: the horizontal brace of a kind of bracing frame or scaffold, comprise the body of rod and the joint that is welded on body of rod both sides, it is characterized in that: described horizontal brace length is 2000mm～3000mm, and the described body of rod is a round tube, and described round tube external diameter is
, described round tube wall thickness is 2mm～3.2mm.
Described round tube external diameter is preferably
Described horizontal brace length is preferably 2062.7mm or 2284.5mm or 2487.0mm or 2771.6mm.
Described round tube wall thickness is preferably 2.5mm or 3.05mm.
Described horizontal brace material is the Q345B structural section.
Described horizontal brace adopts hot dip galvanizing process.
Advantage and the good effect that the utlity model has are:
1, effective and reasonable differentiation and standard be used for the horizontal brace specifications parameter of bracing frame or scaffold;
2, select suitable horizontal brace length, the weight of control cross bar is convenient to workman's carrying and installation, farthest increases work efficiency;
3, adopt the Q345B structural section, effectively raised the bearing capacity of cross bar, reduced total steel quantity of using of bracing frame or scaffold simultaneously;
4, all adopt hot dip galvanizing process to handle inside and outside the horizontal brace, prevent that cross bar from getting rusty and wearing and tearing, and improved the security and stability of whole connection system for guide rail or bracing frame system in abominable environment for use.

The specific embodiment
As shown in Figure 1 and Figure 2, the utility model comprises the body of rod 1 and the joint 2 that is welded on body of rod both sides, and described horizontal brace length is 2000mm～3000mm, and the described body of rod is a round tube, and described round tube external diameter is
, described round tube wall thickness is 2mm～3.2mm.Described round tube external diameter is preferably
Described horizontal brace length is preferably 2062.7mm or 2284.5mm or 2487.0mm or 2771.6mm.Described round tube wall thickness is preferably 2.5mm or 3.05mm.Described horizontal brace material is the Q345B structural section.Described horizontal brace adopts hot dip galvanizing process.If described horizontal brace is used for connection system for guide rail, its round tube wall thickness adopts 3.05mm to get final product, if described horizontal brace is used for the bracing frame system, its round tube wall thickness adopts 2.5mm.
As shown in Figure 3, Figure 4, the agent structure of this bracing frame or scaffold is that the floral disc 3 that will have horizontal brace jack and brace jack is welded in the vertical rod 4.During installation, elder generation aims at horizontal brace jack 5 positions on the described floral disc 3 with joint 2 and pushes, and holds out against vertical rod 4 until joint 2, and then latch 6 being inserted brace jacks 5 and strikes tightly just can be with horizontal brace and vertical rod 4 firm linking together.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limit practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
