Abstract
A kind of bolt fastening spanner suitable for profound small space, including the vertical scalable power transmission rod piece (2) of top band transverse direction handle (1), the cross bolts sleeve for being plugged in power transmission rod piece bottom end；The scalable power transmission rod piece (2) is mutually socketed by two sections of casings and is connected and fixed with pin (4)；The bolt collar includes the plug (3 1) of laterally inserted power transmission rod piece (2) lower part and the hexagonal internal bore sleeve (3 2) positioned at outer end.The utility model solves the problems, such as that profound small space inner bolt is difficult to reinforce, it is ensured that is completely embedded between steel structure column and built-in fitting, reduces operation difficulty, it is ensured that construction work orderly carries out.Its is simple and reliable for structure, low manufacture cost, easy to use.
Description
Technical field
The utility model belongs to construction technical field of tools, particularly for the spanner for tightening reinforcing bolt.
Background technology
When carrying out steel structure column lifting construction, the first pre-buried built-in fitting made in advance in concrete foundation, stay
If high-strength bolt, after the completion of waiting for that catch pit and surrounding concrete pour, then the lifting of steel structure column is carried out, steel structure column is put
On after the built-in fitting positioning of concrete foundation, the high-strength bolt for staying and setting is tightened, realizes the fixation of steel structure column.When catch pit side
When space of planes is smaller, profound small space is formed between steel structure column and catch pit side wall, manual operation cannot be introduced into construction
Position can not cause construction not carry out orderly to staying the high-strength bolt set to carry out tightening reinforcing.
Invention content
The purpose of this utility model be solve the problems, such as it is of the existing technology, provide it is a kind of it is easy to use be suitable for it is profound
The bolt fastening spanner that small space uses.
The purpose of this utility model is achieved through the following technical solutions：
A kind of bolt fastening spanner suitable for profound small space includes the vertical scalable of top band transverse direction handle
Power transmission rod piece, the cross bolts sleeve for being plugged in power transmission rod piece bottom end；The scalable power transmission rod piece is mutually covered by two sections of casings
It connects and is connected and fixed with pin；The bolt collar includes the plug of laterally inserted power transmission rod piece lower part and the hexagonal positioned at outer end
Shape endoporus sleeve.
The utility model is set with antiskid glue sleeve on handle.
The utility model can extend into profound small space by scalable power transmission rod piece, by the spiral shell of power transmission rod piece bottom end
Bolt sleeve is sleeved on built-in fitting and stays on the fastening nut of the high-strength bolt set, is tightened fastening nut by rotating handle, thus will
Steel structure column bottom end is fastenedly connected fixation with built-in fitting, solves the problems, such as that profound small space inner bolt is difficult to reinforce, it is ensured that steel
It is completely embedded between structural column and built-in fitting, reduces operation difficulty, it is ensured that construction work orderly carries out.
The utility model dexterously tightens fastening bolt using lever principle, simple and reliable for structure, low manufacture cost,
It is easy to use.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic diagram that the utility model is applied to construction site；
Fig. 3 is the schematic diagram that bolt is reinforced using the utility model；
Fig. 4 is that the hexagonal internal bore sleeve of the utility model is sleeved on the schematic diagram on pre- retention nut.
Specific implementation mode
The content of the utility model is expanded on further with reference to the accompanying drawings of the specification.
As shown in Figure 1, the bolt fastening spanner described in the utility model suitable for profound small space, including top band
The vertical scalable power transmission rod piece 2 of lateral handle 1, the cross bolts sleeve for being plugged in power transmission rod piece bottom end.It is described scalable
Power transmission rod piece 2 is mutually socketed by two sections of casings and is connected and fixed with pin 4.The bolt collar includes can laterally inserted transmission rod
The plug 3-1 of 2 lower part of part and hexagonal internal bore sleeve 3-2 positioned at outer end.Antiskid glue sleeve 5 is set on handle 1, in order to
Operation.The bolt collar can produce one group according to the model of high-strength bolt, for the high-strength bolt of different model, in power transmission
Rod piece bottom end is equipped with the bolt collar of different model.Bolt collar is processed into integral structure using steel, to ensure its structure
Intensity.
As shown in Figure 2 and Figure 3, when the space between 7 side wall of steel structure column 6 and catch pit is more narrow and depth is deeper,
The pre- retention nut 8 at 10 top of pre-buried high-strength bolt of steel structure column bottom end is fastened using the utility model.At steel structure column bottom
End side wall is installed with handle hole 9 in advance.It is placed in the coagulation soil matrix for having buried built-in fitting high-strength bolt 10 when lifting steel structure column
After on plinth 11, the utility model is extend into steel structure column bottom from narrow space, it will be in the hexagon of cross bolts sleeve
Hole sleeve 3-2 is sleeved on pre- retention nut 8, then rotates handle 1 repeatedly, and scalable power transmission rod piece 2 passes 1 horizontal rotating force of handle
It is sent on bolt collar, drives bolt collar rotation, play the role of tightening pre- retention nut, reinforce high-strength bolt, until by steel
Structural column bottom end is fastenedly connected fixation with concrete foundation.The hexagonal internal bore sleeve 3-2 that Fig. 4 show the utility model is sleeved on
Schematic diagram at the top of pre-buried high-strength bolt 10 on pre- retention nut 8.Handle hole 9, which can avoid steel structure column side wall, makes the utility model
With the interference of operation.Be inserted into and handle length not enough or the arm of force it is smaller when, can jacketed steel pipe with Lengthened moment arm.
