Description
Technical field
The present invention relates to be specially a kind of spanner and method for using thereof that is used for the large-diameter and high-strength bolt for when bolted mode is adopted in the object connection, having the head of special shape or the clamp structure field of bar.
Background technology
The radial Tension Structure System is a kind of full stretching type structure that is derived from the wheel spoke notion; This structure is made up of outer-ring beam, support column, flexible cable truss and interior ring etc.; Outer-ring beam is a space curved beam that is positioned on the saddle face, and outer-ring beam is formed by connecting through flange on pressure ring case beam one by one, and the outer-ring beam cross section is " order " font and horizontal positioned; Because the outer-ring beam axis is not in a plane, radially the Suo Li effect makes the support column under the outer-ring beam partly bear tension; The flexible cable truss divide to be gone up lower edge and is arranged, is concave shaped, forms by flying post, go up last quarter rope and connect the vertical drag-line of going up lower edge, flies post employing round steel pipe cross section; In ring adopt the two sheets of flexible rope, 3 of every layer of horizontal positioned are connected to the two ends up and down that cable truss flies post; Also be furnished with the steel arch in multiple tracks hoop rope and pipe cross section between two adjacent radial cable trusses, cover the PTFE film on the steel arch.Whole roof structure is a self-balancing stress system basically, is placed on the support column that is circular layout.Need in the radial Tension Structure System to use a large amount of high-strength bolts, high-strength bolt all is positioned at pressure ring case beam flange end plate place, and the high-strength bolt specification is big, and nominal diameter can reach 36mm, and the construction moment of torsion is bigger, needs the torque wrench of high standard; Because the main high-strength bolt that leans on is stressed between the flange end plate, therefore the fabrication and installation quality to high-strength bolt has proposed high requirement; Owing to on-the-spot work high above the ground is installed, operating platform is limited, conventional manual work execute twist difficulty and danger bigger.Adopt at present usually to detect and use torque wrench, this torque wrench weight is big, and length is long, and the connection of pressure ring case beam flange end plate is work high above the ground, and the operating space is narrow and small, is difficult to execute stubborn, particularly stubborn to executing of the high-strength bolt of pressure ring case beam bottom, and is difficult.At present structural steelwork the design phase in order to reduce the appearance of welding deformation and welding residual stress; Increased the use to high-strength bolt, the application of super-large diameter high-strength bolt is increasingly extensive, and great majority all need be installed in the high-altitude; It is big to execute stubborn difficulty, and handling safety hidden danger is bigger.
Summary of the invention
In order to overcome the defective of prior art, provide a kind of small and exquisite flexibly, be convenient to operate, fastened tools safe and reliable, applied widely, the invention discloses a kind of spanner and method for using thereof that is used for the large-diameter and high-strength bolt.
The present invention reaches goal of the invention through following technical scheme:
A kind of spanner that is used for the large-diameter and high-strength bolt comprises base plate, it is characterized in that; Also comprise sleeve, an end of base plate has a screw cap hole, and screw cap hole is the regular hexagon hole; The other end of base plate has a connecting hole, and connecting hole is a circular port, and the two ends of base plate all are semicircle; The distance of the outer of the centre-to-centre spacing screw cap hole bottom plate of screw cap hole equals the distance of screw cap hole opposite side; The distance of the outer of the distance of center circle connecting hole bottom plate of connecting hole equals the diameter of connecting hole, and the internal diameter of sleeve is 105%～120% of a baseplate width, and jacket casing is in the outside of base plate connecting hole one end.
The described method for using that is used for the spanner of large-diameter and high-strength bolt is characterized in that: carry out successively as follows:
A. the screw cap hole on the base plate is enclosed within outside the nut of bolt to be tightened, pulls connecting hole one end of base plate with hand,
B. after pulling base plate and tight a bolt in a step, use jacket casing again outside connecting hole one end of base plate, pull sleeve then,
C. after b step tights a bolt with sleeve, take off sleeve, the suspension hook of jack is hooked the connecting hole of base plate, start jack and continue bolt is implemented to tighten until bolted.
The described method for using that is used for the spanner of large-diameter and high-strength bolt is characterized in that: c is during the step, and jack selects for use 2 tons jack that bolt is implemented to tighten.
When the present invention uses; Screw cap hole on the base plate is enclosed within outside the nut of bolt to be tightened, pulls connecting hole one end of base plate with hand, in order to strengthen screwing force; Can also use jacket casing outside connecting hole one end of base plate; Pull sleeve then, in fact played the effect of prolongation lever arm of force through sleeve, thereby reached the purpose that strengthens screwing force.After tighting a bolt with sleeve, take off sleeve, the suspension hook of jack is hooked the connecting hole of base plate, start jack and continue bolt is implemented to tighten, until meeting the bolted requirement.
The present invention is applicable to that the diameter of bolt is big, need bigger construction moment of torsion and the artificial situation that can't meet the demands of twisting of executing, and is applicable to the high-strength bolt installing engineering that high-altitude application and operating space are narrow and small.Adopt the present invention in the high-altitude high-strength bolt to be implemented terminal operation, the higher and construction quality of efficiency of construction is easy to guarantee that the site safety risk is less; Can reach the construction moment of torsion standard of high-strength bolt; Structure stress is met design requirement, can guarantee the safety of work progress again, simple to operate.

The specific embodiment
Below further specify the present invention through specific embodiment.
A kind of spanner that is used for the large-diameter and high-strength bolt, like Fig. 1～shown in Figure 3, concrete structure is: comprise base plate 1 and sleeve 4; One end of base plate 1 has a screw cap hole 2; Screw cap hole 2 is the regular hexagon hole, and the other end of base plate 1 has a connecting hole 3, and connecting hole 3 is a circular port.The two ends of base plate 1 all are semicircle, and the distance of the outer of the centre-to-centre spacing screw cap hole of screw cap hole 22 bottom plates 1 equals the distance of screw cap hole 2 opposite side, and the distance of the outer of the distance of center circle connecting hole of connecting hole 33 bottom plates 1 equals the diameter of connecting hole 3.The internal diameter of sleeve 4 is 105%～120% of base plate 1 width, and present embodiment gets 110%, and sleeve 4 is enclosed within the outside of base plate 1 connecting hole 3 one ends.
When present embodiment uses, as shown in Figure 4, the screw cap hole on the base plate 12 is enclosed within outside the nut of bolt to be tightened; Pull connecting hole 3 one ends of base plate 1 with hand; In order to strengthen screwing force, can also be enclosed within outside connecting hole 3 one ends of base plate 1 with sleeve 4, pull sleeve 4 then; In fact play the effect of prolongation lever arm of force through sleeve 4, thereby reached the purpose that strengthens screwing force.After tighting a bolt with sleeve 4, take off sleeve 4, as shown in Figure 5, the suspension hook of jack 5 is hooked the connecting hole 3 of base plate 1, jack 5 is selected 2 tons of jacks for use, starts jack 5 and continues bolt is implemented to tighten, until meeting the bolted requirement.
