Specific embodiment
It referring to Fig.1, is a kind of adjustable connection structure of light gage steel joist disclosed by the utility model, including sunpender 1, main dragon
Bone 2 and secondary joist 3, grid-shaped setting between main joist 2 and secondary joist 3, between two secondary joists 3 of 2 two sides of main joist
Be connected with connector 4, connector 4 is slidably socketed on main joist 2, be between connector 4 and secondary joist 3 it is prefabricated, when installation,
It only needs for connector 4 to be socketed on main joist 2, structure is simple, is convenient for operation, the side of 2 two sides of main joist along its length
Several clip assemblies 5 have been set up, have been used to connect and fix connector 4, to increase the steady of lightgage steel joist entirety
Qualitative, clip assembly 5 is gradually intensively arranged by both ends to the middle part of main joist 2.
According to the needs of installation, staff can be kept it mobile towards the middle part of main joist 2, then be led to sliding connector 4
It crosses corresponding clip assembly 5 to be fixed, the distance between adjacent secondary joist 3 is adjusted to realize, is installed simultaneously
During do not need special nail piercing equipment, conveniently add secondary joist 3, it is steady after being mounted with lamp decoration to improve lightgage steel joist
Qualitative and stress uniformity.
Referring to Fig. 2 and Fig. 3, main joist 2 is H profile steel comprising web 21 and the wing for being symmetrically fixed in 21 both ends of web
Plate 22, web 21 thicken setting in processing, and the length direction of two lateral edge webs 21 offers several grooves 211 respectively, and two
The groove 211 of side can be symmetrical arranged or shift to install, but by the both ends of web 21 to middle part gradually dense distribution, in the application
It is illustrated for shifting to install.
Referring to Fig. 3 and Fig. 4, clip assembly 5 includes card convex 51 and is connected to card convex 51 and groove 211 far from its opening one
Spring 52 between the inner wall of side, it is generally the case that card convex 51 stretches out groove 211 far from one end of spring 52, when spring 52 is received
When contracting, card convex 51 be can be recycled to the inside of groove 211.
Referring to Fig. 2, connector 4 is U-shaped, and T-type fixed plate 6 is welded between two sides and secondary joist 3, connects for increasing
Contact area between fitting 4 and secondary joist 3, to improve the bonding strength and stability of the two.
Referring to Fig. 4, the two sidewalls of connector 4 are connected with flanging 41 close to the positional symmetry of opening, and two flangings 41 are towards mutual
Close direction extends and is formed gap, passes through for web 21, and the lower surface of the one end close to each other of two flanging 41 is solid respectively
It is connected to the connecting plate 42 extended downwardly, when installation, connector 4 is socketed on main joist 2 by one end of main joist 2, makes two companies
Two sides of the fishplate bar 42 respectively with web 21 fit closely, corresponded on two connecting plates 42 card convex 51 stretching one end open up respectively it is limited
Position hole 421, is used for for 51 grafting of card convex, to indirectly fix to secondary joist 3.
Card convex 51 is connected with anti-drop block 53 close to one end of spring 52, and the inner wall of groove 211 corresponds to the position of anti-drop block 53
Offer the slideway 2111 slided for anti-drop block 53, the setting of anti-drop block 53 prevents it from recessed for limiting to card convex 51
Abjection in slot 211, and card convex 51 and limit hole 421(is caused to see Fig. 3) between can not stablize cooperation.
Referring to Fig. 3 and Fig. 4, when adjusting, shackle member is pressed, is retracted to it in groove 211, then along the length of main joist 2
Direction mobile connection part 4 is spent, when moving to the appropriate position, shackle member automatic spring, and it is plugged to corresponding limit hole 421
In, that is, realize the adjusting to spacing between secondary joist 3.
Further, the one end of card convex 51 far from spring 52 is spherical surface, which makes staff only need to press lightly on
Connector 4 can be pushed to slide, reduce the frictional force between card convex 51 and connector 4, more convenient staff to its into
Row operation.
Referring to Fig. 3 and Fig. 4, the both ends on connecting plate 42 along its length are respectively equipped with gap 422, with limit hole
It is located at sustained height between 421, when staff pushes at connector 4 to card convex 51, due to the setting of gap 422, connection
Part 4 can preferably be cooperated between the spherical surface of card convex 51, i.e., be able to drive spring under the action of by thrust in card convex 51
52 shrink, to be retracted in groove 211, facilitate staff and install.
When 4 stress of connector, the connecting plates 42 of two sides may run-off the straight deformation, cause card convex 51 not insert normally
It connects in limit hole 421, and then connector 4 can not be fixed, the final stability for influencing reinforcing bar keel, when serious
Be likely to result in some potential safety problems, in order to solve the above technical problems, make connecting plate 42 extend downwardly and with it is remote on main joist 2
Wing plate 22 from 1 one end of sunpender abuts against, and is correspondingly connected on the wing plate 22 42 end face of plate and offers limit for its grafting
Slot 221, the length direction along wing plate 22 extend.
When connector 4 is socketed on main joist 2, the connecting plate 42 of two sides is plugged to corresponding limiting slot 221 respectively
It is interior, prevent connector 4 in the case where stress, both side plate misplaces.
Referring to Fig. 2, sunpender 1 is arranged on connector 4, connects with one end and connector 4 far from the side screw thread of flanging 41
It connects, the other end can be fixed on floor by expansion bolt, and the setting of threaded connection is readily transported, while facilitating staff
In-site installation.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
