Description
Technical field
The present invention relates to a kind of construction method of the plug-in type truss member with rubbing surface self-protection function.
Background technology
Steel truss structure has stronger span ability, is widely used in building structure, bridge structure.At present, large span
Using integral node, web member to be connected with integral node using high-strength bolt steel truss girder bridge more.The connection of web member and integral node
Mode has two kinds, and one kind is that, to spelling formula, another kind is plug-in type.Wherein, plug-in type truss member simple structure, economic performance
Good, stress reliability, it is general using drum section, it is especially common in Practical Project.
But, plug-in type truss member has a contradiction point in design and construction, is exactly plug-in type rod member and be inserted into section
Gap between point.Wish that this gap is the smaller the better from design angle, so just can guarantee that the coefficient of friction of rubbing surface is effective
Play, it is ensured that structure stress safety.But this gap is too small, the problem brought first is exactly installation difficulty, influence construct into
Degree；Even if rod member is installed, Rod end causes the damage of rubbing surface when rubbing surface is passed through, inevitably, and
Later stage cannot repair, and this will directly affect the bearing capacity and durability of structure.Therefore, this is just wished from construction angle
Gap is big as far as possible.In order to meet the demand of design and construction simultaneously, the accuracy of manufacture requirement of plug-in type rod member is just very high.It is real
In the engineering of border, it is difficult to ensure that rubbing surface is not destroyed in work progress.
The content of the invention
Regarding the issue above, the present invention provides one kind both can guarantee that plug-in type truss member smoothly inserted node
The plug-in type purlin with rubbing surface self-protection function of high-strength bolt rubbing surface, simple structure, easy construction can be effectively protected again
The construction method of hack lever part.
The purpose of the present invention is achieved through the following technical solutions, the plug-in type truss with rubbing surface self-protection function
The construction method of rod member, comprises the following steps that：
1) notch is preset in the centre position of plug-in type truss member end web, in notch length range, notch will
Plug-in type truss member end web separate, two risers of plug-in type truss member respectively with the plug-in type truss member for being separated
End web part constitutes T-shaped section；
2) along notch both sides, bolt hole one, the hole between bolt hole one are preset on the web of plug-in type truss member end
Away from being pitch-row one；Bolt hole two is preset on the plug-in type truss member end web of notch end both sides, between bolt hole two
Pitch-row is pitch-row two；
3) bolt hole three corresponding with bolt hole two is set in prestretching fixed plate, and the pitch-row between bolt hole three is pitch-row
Three, pitch-row two is more than pitch-row three；
4) bolt hole four is set in web splice plate, the pitch-row between bolt hole four is pitch-row four, pitch-row four and pitch-row one
It is equal；
5) bolt on plug-in type truss member end web and prestretching fixed plate is passed through with positioning punch or high-strength bolt
Hole two, three；
6) gusset plate is inserted into the plug-in type truss member end with rubbing surface self-protection function；
7) after the plug-in type truss member with rubbing surface self-protection function is installed in place, the positioning exited in bolt hole two
Punch or high-strength bolt, plug-in type truss member riser will voluntarily recover with the elastic deformation of end web；
8) high-strength bolt carried out between gusset plate and riser applies stubborn；
9) the plug-in type truss member end web of default notch both sides is coupled together using web splice plate, has been constructed
Into.
It is of the invention to eliminate dovetail groove compared with traditional plug-in type rod member rod end is constructed, prestretching fixation steel plate is employed,
Make riser that elastic deformation occur with the web part for being separated by pretension, be effectively protected rubbing surface；Present invention construction
Details stress reliability, easy construction, simple to operate, saving construction cost.
The present invention both can be applied to plug-in type truss drum rod member, can also be applied to plug-in type truss box type rod piece.
Brief description of the drawings
Fig. 1 is plug-in type rod end structural map,
Fig. 2 is A--A profiles in Fig. 1,
Fig. 3 is prestretching fixed plate structural map,
Fig. 4 is web splice plate structural map,
Fig. 5 is that plug-in type truss member rod end dispatches from the factory installation diagram,
Fig. 6, Fig. 7, Fig. 8 are each stage scheme of installations of plug-in type truss member rod end.
Specific embodiment
With reference to the accompanying drawings, by taking the scheme that drum plug-in type truss member, end do not set dovetail groove as an example, this is elaborated
Invention.
1) notch 1, in notch length range, notch 1 are preset in the centre position of plug-in type truss member end web 9
By Rod end web 9 separate (see Fig. 1), two risers 10 of plug-in type truss member respectively with the plug-in type truss for being separated
The part of Rod end web 9 composition T-shaped section as described in Figure 2.
Plug-in type truss member is drum, i.e., there is one web plug-in type truss member end；Or box, i.e. plug-in type
There is twice web truss member end.
2) along the both sides of notch 1, bolt hole 1 is preset on plug-in type truss member end web 9, between bolt hole one
Pitch-row is pitch-row one；On the plug-in type truss member end web 9 of the end both sides of notch 1 preset bolt hole 22, bolt hole two it
Between pitch-row be pitch-row two, be reduce stress concentration, set circular port in the afterbody of notch 1 (see Fig. 1).
3) bolt hole 3 11 corresponding with bolt hole 22 is set in prestretching fixed plate 6, and the pitch-row between bolt hole three is
Pitch-row three (see Fig. 3), pitch-row two is more than pitch-row three.It is predeterminable on plug-in type truss member end web 9 according to stress needs
One or more bolts hole 22, predeterminable one or more bolts hole 3 11 in prestretching fixed plate 6.
4) bolt hole 4 12 corresponding with bolt hole one is set in web splice plate 8, the pitch-row between bolt hole four is hole
Away from four, pitch-row four is equal with pitch-row one (see Fig. 1,4).
5) spiral shell on plug-in type truss member end web 9 and prestretching fixed plate 6 is passed through with positioning punch or high-strength bolt 3
Keyhole two, three (see Fig. 5), because pitch-row two is more than pitch-row three, therefore after prestretching fixed plate 6 is installed in place, riser 10 with separated
The web part elastic deformation that will occur jointly to rod member centerline side.Such as using positioning punch, then need to set safety plug, prevent
Only punch is positioned in transportation to drop.
6) gusset plate 5 is inserted at the plug-in type truss member end with rubbing surface self-protection function (see Fig. 7,8).Due to perpendicular
There is elastic deformation in plate 10, therefore plug-in type truss member end can be easily inserted gusset plate 5 with the web part for being separated,
It is effectively protected rubbing surface 7, therefore claims it there is rubbing surface self-protection function.
7) after the plug-in type truss member with rubbing surface self-protection function is installed in place, determining in bolt hole 22 is exited
Position punch or high-strength bolt 3 (see Fig. 6), riser 10 will voluntarily recover with the elastic deformation of the web part for being separated.
8) high-strength bolt carried out between gusset plate 5 and riser 10 applies stubborn；
9) coupled together the plug-in type truss member end web 9 of the both sides of default notch 1 using web splice plate 8 (see
Fig. 7,8), construction is completed.
It is of the invention to eliminate dovetail groove compared with traditional plug-in type rod member rod end is constructed, prestretching fixation steel plate is employed,
Make riser that elastic deformation occur with plug-in type truss member end web separate part by pretension, be effectively protected friction
Face, simple structure, easy construction substantially increases the reliability of rubbing surface.
