Abstract
The utility model relates to the field of steel structure buildings, and particularly relates to a truss structure and a lightweight steel roof support tightening pull rod. The pull rod comprises at least two rod pieces, a casting sleeve, and casting connecting ends, wherein each rod piece is connected with one connecting end by a thread; the rod pieces are connected with each other through the casting sleeve and can be tightened by threads; the threads at the two ends of each rod piece spiral oppositely; the density of the threads between each rod piece and the connecting end is three times that of the threads between each rod piece and the casting sleeve. The structure of a turn buckle is changed, the casting connecting ends and the casting sleeve are adopted as the connecting means of the rod pieces, although the cost is increased slightly, the safety is enhanced greatly, and the pull rod is practical and reliable. The threads at the two ends of each rod piece spiral oppositely, so that the two ends of the each rod piece can be conveniently tightened or loosened at the same time; since the connecting ends are liable to damage and high in utilization frequency, the density of the threads of the rod pieces and the connecting ends is increased to achieve a firm effect.
Description
Technical field
The utility model relates to steel building field, refers in particular to a kind of trussed construction and light-steel roofing and supports and tighten up pull bar.
Background technology
Along with the development of construction market, more and more high-rise, Super High employing full steel structures, are made as main structure with steel, are one of main building construction types in recent years.The feature of steel be intensity high, from heavy and light, integral rigidity is good, deformability is strong, therefore for building large span and superelevation, extra-duty building is suitable especially; Material homogeneity and isotropism are good, belong to perfect elastic body, meet the basic assumption of common engineering mechanics most; Material plasticity, good toughness, can have moderate finite deformation, can bear well dynamic loading; Construction period is short; Its industrialization degree is high, can carry out the specialization that mechanization degree is high and produce.
It is all that the zinc-plated flower basket bolt that utilizes round steel and market to buy is combined conventionally that current trussed construction and light-steel roofing support, being used for doing roof inclined supports, through experiment, position is tightened up in discovery and rod member welding does not reach requirement of strength, in practice, there is the existence of fracture, can bring hidden danger to safety.
Summary of the invention
For overcoming the above problems, it is a kind of simple in structure that the utility model provides, and safe trussed construction and light-steel roofing support and tighten up pull bar.
Trussed construction and light-steel roofing support and tighten up pull bar, comprise at least 2 rod members, foundry goods sleeve pipe and foundry goods link, and rod member and link are threaded connection; Between rod member, connect and can tighten up by screw thread by foundry goods sleeve pipe; The screw thread at described rod member two ends is mutual spiral in the other direction; The thread density of rod member and link is 3 times of thread density between rod member and sleeve pipe.
As a kind of improvement of the present utility model, described foundry goods link is u shaped connector, and U-shaped wall is provided with the through hole that inserts pin.
As a kind of improvement of the present utility model, on described foundry goods sleeve pipe, be also provided with through hole.
The utility model has changed the structure of flower basket bolt, and the link of employing foundry goods and sleeve are as the connected mode of rod member, although rising to some extent on cost,, safety improves greatly, and practicality is reliable.The screw thread at rod member two ends is mutual spiral in the other direction, facilitates rod member two ends tighten up simultaneously or unclamp; Because link is fragile, and frequency of utilization is higher, has increased the thread density of rod member and link, more firm.
Accompanying drawing explanation
Fig. 1 is perspective structure schematic diagram of the present utility model.
Fig. 2 is the perspective structure schematic diagram that the utility model is equipped with bolt.
The specific embodiment
As shown in Figure 1-2, trussed construction and light-steel roofing support and tighten up pull bar, comprise rod member 1 and foundry goods link 2, and rod member 1 and link 2 are threaded connection.Also comprise foundry goods sleeve pipe 3, described rod member 1 is 2 (can be also one or more), between rod member 1, is connected and can be tightened up by screw thread by foundry goods sleeve pipe 3.The screw thread at described rod member 1 two ends is mutual in the other direction spiral, corresponding link 2 and rod member 1(or end 2) hand of thread spiral be also opposite direction mutually.
Wherein, the thread density of rod member 1 and link 2 is 3 times of thread density between rod member 1 and sleeve pipe 3.Described foundry goods link 2 is u shaped connector, and U-shaped wall is provided with the through hole 2-1 that inserts pin 2-3, on described foundry goods sleeve pipe 3, is also provided with through hole 3-1.
