Include the first connector 211 and convex into the second stitching section 22 of the end of the second Two bors d's oeuveres shaped steel 12, first stitching section 21
The first plush copper 212 of the first connector 211 is stretched out, the second stitching section 22 is adapted with the first stitching section 21, the second stitching section 22
The second connector 221 and convex including docking connection with the first plush copper 212 stretch out the second plush copper of the second connector 221
222, second plush copper 222 docks connection with the first connector 211.
Passing through the setting of the first plush copper and the second plush copper so that splicing construction forms wrong head docking and connected, and such first
The piece of the splicing end of the Two bors d's oeuveres shaped steel 12 of Two bors d's oeuveres shaped steel 11 and second is nonlinear type, and it is strong to improve the structure being spliced into
Degree so that the Two bors d's oeuveres shaped steel purlin stress of splicing is more stable, it can be ensured that pattern foundation pit supporting structure safety and stably.
Shown as shown in Figure 1, Figure 3 and Figure 4 as a better embodiment of the present utility model, the splicing construction 20 also includes
It is attached at the first splice plate 23 of the first plush copper 212 and the joint of the second connector 221 and is attached at the second plush copper 222 and first
Second splice plate 24 of the joint of connector 211, first splice plate 23 are sticked in the first plush copper 212 and the second connector 221
Outside and be bolted connection and be located at the first plush copper in the first plush copper 212 and the second connector 221, the first splice plate 23
212 and second connector 221 joint and the flange plate for the H profile steel being partially disposed at the first plush copper 212 on, be also partially disposed in
On the flange plate of H profile steel at second connector 221, the first splice plate 23 is fastenedly connected by bolt with corresponding flange plate.
Second splice plate 24 is sticked in the outside of the second plush copper 222 and the first connector 211 and is bolted connection in second
The connector 211 of plush copper 222 and first, the second splice plate 24 is located at the joint of the second plush copper 222 and the first connector 211 and portion
On the flange plate of H profile steel at second plush copper 222 that is placed in, the flange plate for the H profile steel being also partially disposed at the first connector 211
On, the second splice plate 24 is fastenedly connected by bolt with corresponding flange plate.
It is as depicted in figs. 1 and 2, convex in the first plush copper 212 and second as another better embodiment of the present utility model
First 222 place of being affixed is fastenedly connected by connecting bolt 25.Because the first plush copper 212 protrudes out the first connector 211, second is convex
First 222 protrude out the second connector 221, so dock splice when, H profile steel at the second plush copper 222 and the first plush copper 211
Flange plate can be fitted, and two flange plates of fitting are fastenedly connected by connecting bolt 25.The connecting bolt 25 is multiple, in a row
It is installed on two flange plates of fitting, the connecting bolt 25 positioned at the end of the second plush copper 222 is close to the first connector 211
End set.So cause splicing construction the first plush copper and the first connector, and the second plush copper and the second connector it is mutually wrong
The distance opened is the size that connecting bolt 25 is set, and the distance to stagger should not be too small, because of the connection for needing to meet connecting bolt
Size, the distance to stagger can not be too big, and conference of staggering is because connecting bolt influences away from too far away the power transmission of shaped steel purlin
Performance.So the distance to stagger is arranged to the size that connecting bolt 25 sets, it can be ensured that the transmission force property of shaped steel purlin, really
Protect splicing construction firm and stably.
It is shown as shown in Figure 1, Figure 3 and Figure 4 as another better embodiment of the present utility model, in the first plush copper 212 and
The joint of two connectors 221 is provided with and put more energy into floor 26, the joint of the second plush copper 222 and the first connector 211 also be provided with plus
Strength floor 26.Put more energy into floor 26 by setting to strengthen the structural strength of splicing construction, so that it is guaranteed that splicing construction firm and
Stable, specifically, floor 26 of the putting more energy into web corresponding with H profile steel is fastenedly connected.
As another better embodiment of the present utility model, the end of the first plush copper 212 and the docking of the second connector 221
The first connecting plate 27 is equipped with, two the first connecting plates 27 are affixed merging and are bolted connection；Second plush copper 222 and first
The end of the docking of connector 221 is equipped with the second connecting plate 28, and two the second connecting plates 28 are affixed merging and are fastened by bolts
Connection.In the end set connecting plate of Two bors d's oeuveres shaped steel docking, docking, two connecting plates are affixed merging and are bolted connection.
After connecting plate is set, put more energy into floor 26 not only can web corresponding with H profile steel be fastenedly connected, can also with connecting plate fasten connect
Connect.
The joint of the utility model assembling-type combination steel purlin is cross-linked having the beneficial effect that for structure：
Two bors d's oeuveres H profile steel purlin is connected by the way of the splicing of wrong head, and distance is staggered to be connected during splicing in both sides purlin end
The size of bolt, the distance that staggers can not be too small, otherwise can not meet that bolt splices size, the distance that staggers can not be too big, otherwise
The transmission force property of purlin can be influenceed away from too far away due to bolt.The joint place of first plush copper and the second plush copper, using shaped steel certainly
The flange plate of body is spliced by high-strength bolt, can solve additional splicing plate so that the flange plate contact of purlin is close.
Splice plate is set in the outside of shaped steel and spliced by high-strength bolt and is connected.Power transmission is set to put more energy into floor in purlin end, and
Connected by high-strength bolt.H profile steel purlin mistake head splicing can effectively save splice plate dosage, bolt quantity, can also improve and apply
Work efficiency rate, improve the stress performance of purlin.
The utility model is described in detail above in association with accompanying drawing embodiment, those skilled in the art can root
Many variations example is made to the utility model according to described above.Thus, some details in embodiment should not be formed to this practicality
New restriction, the utility model will be used as the scope of protection of the utility model using the scope that appended claims define.
