Abstract
The utility model discloses a kind of roofing square steel tube primary and secondary purlin and connect node, including main purlin, secondary purlin and connecting plate, the U-shape that described connecting plate is made up of two blocks of side plates and base plate, the same side of two blocks of side plates and base plate is welded on main purlin, and the notch of connecting plate is upward, one end of described purlin is positioned at the notch of connecting plate, and secondary purlin is bolted connection with connecting plate.After the lifting of secondary purlin is in place, bottom has U-shaped link slot to hold, and need not just fix with bolt at once, until purlin in batch all lift in place after, integrated connection in batch, eliminate installer's waiting time when lifting purlin, substantially increase installation effectiveness；On the most U-shaped link slot, connecting hole is split into ellipse, is connected with secondary purlin after fixing, in use freely can stretch along with the deformation of roofing, it is to avoid roofing and purlin node are drawn bad, it is ensured that the connection safety of node.
Description
Technical field
This utility model belongs to connection joints of steel structure, particularly relates to a kind of roofing square steel tube primary and secondary purlin and connects node.
Background technology
In large space structure roofing, owing to main purlin spacing is too big, cause roof boarding span too big, thus cause room
Panel design is unreasonable, so roofing generally uses the mode that primary and secondary purlin combines；Owing to the specification of primary and secondary purlin is different, permissible
Being the forms such as clod wash C-type steel, H profile steel, square steel tube, primary and secondary purlin absolute altitude also has difference simultaneously, and this results in primary and secondary purlin even
Connect the difference of node, and the quality of node type of attachment and switching performance brings shadow can to construction and roofing holistic resistant behavior
Loud, only appropriate design purlin node guarantee roofing construction convenience and structural safety.
Summary of the invention
In order to solve problems of the prior art, it is an object of the invention to provide a kind of roofing square steel tube primary and secondary purlin
Connect node.
In order to realize foregoing invention purpose, the technical scheme that this utility model employing is as described below:
A kind of roofing square steel tube primary and secondary purlin connects node, and including main purlin, secondary purlin and connecting plate, described connecting plate is
The U-shape being made up of two blocks of side plates and base plate, the same side of two blocks of side plates and base plate is welded on main purlin, and connecting plate
Upward, one end of described purlin is positioned at the notch of connecting plate to notch, and secondary purlin is bolted connection with connecting plate.
Preferably, two blocks of side plates of connecting plate offer bar shaped elongated hole respectively, by bolt through bar shaped elongated hole with secondary
Purlin makes time purlin firmly be connected with connecting plate.
Preferably, constitute two blocks of side plates of connecting plate and base plate is formed in one structure.
Preferably, described connecting plate is made up of steel plate bending.
Owing to using technique scheme, this utility model has a following superiority:
After the lifting of secondary purlin is in place, bottom has U-shaped link slot to hold, and just need not fix with bolt at once, treat purlin in batch
All lift in place after, integrated connection in batch, eliminate installer lift purlin time waiting time, substantially increase installation
Efficiency；On the most U-shaped link slot, connecting hole is split into ellipse, is connected after fixing with secondary purlin, in use can be along with roofing
Deformation freely stretch, it is to avoid roofing and purlin node are drawn bad, it is ensured that the connection safety of node.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: the main purlin of 1-；2-purlin；3-connecting plate；4-bolt；5-bar shaped elongated hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings and the technical solution of the utility model is described in further detail by embodiment.
As it is shown in figure 1, a kind of roofing square steel tube primary and secondary purlin connects node, including main purlin 1, secondary purlin 2 and connecting plate
3, the U-shape that described connecting plate 3 is made up of two blocks of side plates and base plate, the same side of two blocks of side plates and base plate is welded on main purlin
On bar 1, and the notch of connecting plate 3 is upward, and one end of described purlin 2 is positioned at the notch of connecting plate 3, secondary purlin 2 be connected
Plate 3 is bolted connection, and two blocks of side plates of connecting plate 3 offer bar shaped elongated hole 5 respectively, by bolt 4 through bar shaped
Elongated hole 5 and time purlin 2 make time purlin firmly be connected with connecting plate.
Constitute two blocks of side plates of connecting plate 3 and base plate is formed in one structure.
Described connecting plate 3 is made up of steel plate bending.
Concrete fabrication and installation step of the present utility model is:
1) select to make the plate size of connecting plate by Force Calculation and structure；
2) on plate, disciform bar shaped elongated hole is opened by location；
3) steel plate is bent into by size the U-shaped shape connecting plate of needs；
4) upwards being welded in factory with main purlin by the notch of connecting plate, weld size, absolute altitude, horizontal level are by calculating really
Fixed；
5) on-site hoisting time purlin is placed in the notch of connecting plate, adjusts and makes the bolt hole on time purlin and bar shaped elongated hole pair
Should；
6) secondary purlin is tightened with bolt by the gross with U-type groove it is connected.
