Abstract
The utility model provides a diagonal rod for a bracing frame or a scaffold, which comprises a rod body and joints provided at two sides of the rod body. The rod body is a circular pipe which is flattened at two ends and is provided with openings at the flattened parts. The joints are connected with the rod body through bolts. The bolts are shouldered tap bolts. Each shouldered tap bolt comprises the following components successively from top to bottom: a bolt head, a cylinder and a screwed rod. The diagonal rod is made of Q345B type steel through a galvanizing process. The diagonal rod for bracing frame or a scaffold has the following beneficial effects: simple structure, large bearing capacity, standard component, rational weight, steel material saving, easy mounting and conveying.
Description
Technical field
The utility model relates to a kind of bracing frame or scaffold member, especially relates to a kind of bracing frame or scaffold brace.
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 scaffold brace installing and carry.
The technical solution of the utility model is: a kind of bracing frame or scaffold brace, comprise the body of rod and the joint that is positioned at body of rod both sides, the described body of rod is the round tube of two flattening and flattening place perforate, described joint is connected with the described body of rod by bolt, described bolt is a shouldered tap bolt, and described shouldered tap bolt comprises bolt head, cylinder table and threaded rod from top to bottom successively.
Described round tube external diameter is
Described round tube length is 1100mm～3200mm, and described round tube wall thickness is 2mm～3mm.
Described round tube external diameter is preferably
Described round tube length is preferably 1163.4mm or 1324.9mm or 1763.6mm or 2015.1mm or 1627.3mm or 1745.2mm or 2095.7mm or 2310.7mm or 2788.9mm or 3091.4mm.
Described round tube wall thickness is preferably 2.5mm.
Described brace material is the Q345B structural section.
Described brace adopts hot dip galvanizing process.
Advantage and the good effect that the utlity model has are:
1, select suitable brace length, the weight of control cross bar is convenient to workman's carrying and installation, farthest increases work efficiency;
2, the body of rod adopts band shoulder nut to be connected with joint, and the active force between the body of rod and the joint acts on the cylinder table of band shoulder nut, can better bear the torsion of connection system for guide rail or bracing frame system, has increased security performance.
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 brace, prevent that cross bar from getting rusty and wearing and tearing, and improved the security and stability of bracing frame or scaffold in abominable environment for use.
