Abstract
The utility model discloses a kind of socket joint type disk button steel pipe scaffold prestressing force braces, including the body of rod, the body of rod is the two-part structure coaxially laid, tapped prestressing nut is installed in the opposite end inner cavity of two bodies of rod, the internal screw thread direction of rotation of two prestressing nuts is opposite, it is linked together between two prestressing nuts by the prestressing force screw rod coaxially laid, block is provided in the middle part of prestressing force screw rod and screws portion between two prestressing nuts.The utility model advantage is that structure is simple, installs and using easy.Portion is screwed using the torque value and rotation of principle of virtual work calibration torque wrench, achieve the purpose that adjust brace length, accurately design prestress value is applied on brace, initial tensile stress is applied to brace, part brace caused by avoiding because of reasons such as foozle, deformations cannot be properly mounted on just in upright bar terminal pad, the problems such as scaffold is loosened, deformed is avoided, the torsional rigidity and overall stability of scaffolding structure are improved.
Description
Technical field
The utility model relates to steel pipe scaffolds, oblique more particularly, to a kind of socket joint type disk button steel pipe scaffold prestressing force
Bar.
Background technique
For solving vertically and horizontally transport, shuttering supporting, security protection etc. when scaffold is construction site worker operation
Problem and the various brackets set up, are temporary structures important in building construction process.Scaffold is usually by bamboo and wood, steel pipe
Or synthetic material etc. is built, steel pipe scaffold sets up mode and can be divided into fastener type steel pipe scaffold, bowl buckle according to different
Formula steel pipe scaffold, gate type steel pipe scaffold, socket joint type disk button steel pipe scaffold.
Socket joint type disk button steel pipe scaffold is formed by connecting by upright bar, horizontal brace rod and oblique reinforcing bar, and level is even
Extension bar and oblique reinforcing bar are referred to as brace；When building connection, upright bar is connected using casing socket joint, and brace then uses rod end to buckle
Connector is caught in the connection type of terminal pad, i.e., is loaded on a terminal pad fixing sleeve at the node of upright bar, opens up in terminal pad slotting
Hole is connect, connector of the lower surface with bolt is set in the rod end of brace, completes to stand by fastening bolt in insertion spliced eye
Connection between bar and brace.The brace of existing socket joint type disk button steel pipe scaffold is all made of the rod piece of regular length, does not have
Device for prestressing, due to foozle, deformation etc., part brace cannot be properly mounted on upright bar terminal pad just
On, there are loosening, deformation the problems such as, influence the lateral resistance behavior and overall stability of entire scaffolding structure to a certain extent.
Summary of the invention
The utility model aim is to provide that a kind of structure is simple, facilitates the socket joint type disk button steel pipe scaffold of adjusting pre-
Stress brace.
To achieve the above object, the utility model can take following technical proposals:
Socket joint type disk button steel pipe scaffold prestressing force brace described in the utility model, including the body of rod, the body of rod be
The two-part structure coaxially laid is installed with tapped prestressing nut in the opposite end inner cavity of two bodies of rod, described in two
The internal screw thread direction of rotation of prestressing nut is on the contrary, be linked as one by the prestressing force screw rod coaxially laid between two prestressing nuts
Body is provided with block in the middle part of the prestressing force screw rod and screws portion between two prestressing nuts.
The section for screwing portion is in regular hexagon structure.
The utility model advantage is that structure is simple, installs and using easy.Utilize principle of virtual work calibration torque wrench
Torque value, and portion is screwed by torque wrench rotation, make two sections of bodies of rod of brace while elongating or shortening, it is long to reach adjustment brace
Design prestress value, is accurately applied on brace by the purpose of degree, applies initial tensile stress to brace, avoids missing because of manufacture
Part brace caused by the reasons such as difference, deformation cannot be properly mounted on just in upright bar terminal pad, avoid scaffold pine
The problems such as moving, deforming, improves the torsional rigidity and overall stability of scaffolding structure.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the sectional view along A-A of Fig. 1.
Specific embodiment
As shown in Figure 1, 2, socket joint type disk button steel pipe scaffold prestressing force brace described in the utility model, including the body of rod
Brace in 1(, that is, scaffold is divided into two kinds of horizontal brace rod and oblique reinforcing bar), the body of rod 1 is the two-part knot coaxially laid
Structure is installed with tapped prestressing nut 2, the internal screw thread rotation of two prestressing nuts 2 in the opposite end inner cavity of two bodies of rod 1
Turn contrary, is linked together between two prestressing nuts 2 by the prestressing force screw rod 3 coaxially laid, i.e., in prestressing force screw rod 3
It is upper to open up external screw thread compatible with the internal screw thread of prestressing nut 2 of two sides respectively, when rotating prestressing force screw rod 3, two sides
Prestressing nut 2 to will drive the body of rod 1 opposite simultaneously or backwards to moving, achieve the purpose that adjust brace length；In addition, for convenience
Prestressing force screw rod 3 is rotated, block is provided in the middle and screws portion 4 between two prestressing nuts 2, for convenience of torque spanner
Clamping, screw the section in portion 4 in regular hexagon structure.
When actual installation, connector is connected in the outer end of two bodies of rod first, and is installed in the terminal pad at upright bar node,
The torque M for demarcating torque wrench by principle of virtual work Md θ=Fdl later screws portion 4 with torque wrench clamping and rotates, quasi-
True is applied to design prestressing force F on brace, to apply initial tensile stress to brace, completes the adjustment to brace length,
Improve the torsional rigidity and overall stability of scaffolding structure.
