It is a part of in pit；Then, external hexagonal sleeve 14 is twisted with spanner, drives shank of bolt 13 to rotate, until reaching setting torsion；
4) and then by spanner taken out out of installation operation hole 10, installation cover plate combination part 4, two sections of box-type section bars of completion
It is fixedly connected.
The operation instruction of the utility model under different operating conditions.
Referring to Fig. 10, the utility model embodiment one：The utility model general assemble formula interconnection technique is based on for one kind
Box-type section assembling frame.Box-type section is also section form preferred in frame structure, but by assembled interconnection technique
Restriction causes existing assembling frame frequently with H types or i shaped cross section.Skill is connected using general assemble formula of the present utility model
Art, a kind of general box-type section assembling frame system can be formed with the above-mentioned restriction of more economical cost breakthrough.Such as Figure 10,
The inflection point of box-type section frame column nearby sets general assemble formula connection system of the present utility model, and connection end plate is according in post
Power characteristic Design, the structural behaviour of approximate welding integral post can be achieved.For the ease of installation, under end plate A 1 and upper shell of column
End is connected, and end plate B 2 is fixed on lower shell of column upper end.Similarly, the utility model interconnection technique is applied on Vierendeel girder, also can be real
Existing block assembly.Two kinds of forms are often had according to joint face position difference on beam：1) the first is such as Figure 10 a, Vierendeel girder across
Middle setting the utility model universal connecting system.Every Vierendeel girder span centre need to only set 1 set of connection system, end plate A 1 and end plate B
2 is interchangeable, only need to ensure that each joint face is supporting.This assembling frame system joint face is few, and installation is fast, integral rigidity
Greatly, but component conveying requires higher, similar common assembling frame system.2) second of such as Figure 10 b, it is different from the former,
The both ends of beam respectively set a set of the utility model connection system, and joint face adjusts segment distance from beam-ends to centre.Every frame
Set a roof beam in place and be divided into three sections, including the small short beam that longer middle part beam body and both ends respectively are isolated by.The small short beam one end and framework
The strong welds such as post, the other end are fixed with end plate B 2；And middle part beam body both ends are supporting is fixed with end plate A 1.On such frame column
The beam section of welding is shorter, is readily transported and lifts；Moreover, by rationally designing connection system rotational stiffness and ultimate bending moment, can
Formed one " specified plastic hinge ", similar to dog bone type Vierendeel girder, there is more preferable static characteristics and energy consumption ability.It is actual
In, from overall structure performance, the position of Reasonable adjustment assembled connection system and mechanical characteristic, structure can be designed
The assembling frame system of excellent performance and economical and efficient.The embodiment especially suitable for all kinds of multi and tall steel building buildings,
The structure such as superelevation power transmission tower and storage rack.
Refer to Figure 11 and 12, the utility model embodiment two：For the utility model general assemble formula connect system to
Realize the assembling of box-type section continuous rigid frame bridge and arch bridge.The arch rib of arch bridge, the bridge floor girder of continuous rigid frame bridge and bridge pier are normal
Larger biaxial bending is subjected to, is most ideal chose using box-shaped section component.In existing continuous rigid frame bridge, for section chi
Very little larger component, often takes tank wall perforate, and workmen enters installation in chamber；For the less structure of sectional dimension
Part, often abandon box-type section because interconnection technique limits.Using the utility model general assemble formula interconnection technique, without tank wall
Box-shaped section component assembling can be conveniently realized under conditions of perforate, is solved the above problems.It is that box-type section is T-shaped just such as Figure 11
Structure, in the less section of moment of flexure the utility model general assemble formula can be set to connect system, by continuous T-shaped just structure be decomposed into compared with
Subsection, it is easy to implement plant produced and Fast Installation；Similarly such as Figure 12, by reasonable Arrangement and joint face is designed, using this
Longer and bending arch rib can also be realized segmentation by utility model technology, be easy to industrialized production and Fast Installation, at the same again without
It need to worry and larger cost is paid in outward appearance and mechanical property.When the arch rib of bridge, bridge floor and pier section size increase, always
Section can be decomposed into the combination of multiple small size chambers, or design by assembling of the present utility model connection theory large-scale
Special end plate.Certainly, the utility model assembled interconnection technique can also be used for simply supported girder bridge, continuous bridge, cable-stayed bridge or hand basket
The bridge of the other structures type such as arch bridge.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
