Embodiment
To make the goal of the invention, technical scheme and beneficial effect of the present invention of greater clarity, with reference to
Accompanying drawing is illustrated to embodiments of the invention, it is necessary to explanation is, in the case where not conflicting, this Shen
Please in embodiment and embodiment in feature can mutually be combined.
Fig. 1 is referred to, Fig. 1 is main joist and secondary joist attachment structure schematic diagram；A kind of main joist and time
Keel connecting structure, including (secondary joist is two under normal circumstances, such as Fig. 1 for main joist 3 and secondary joist
Shown in, including the first secondary joist 4 and the second secondary joist 5, the first secondary joist 4 and the second secondary joist 5
It is linearly arranged in same plane), the main joist 3 and the secondary joist are intersecting to be set, in the master
Keel and the secondary joist intersection location are connected by connector, and the connector is inserted with the main joist 3
Connect in succession, the connector is connected with the secondary joist clamping, in order to from side by the connector with dragon
Bone skeleton is fixed, and forms three-dimensional connected mode, and connector passes through bolt 6 with the secondary joist simultaneously
Connection.
The concrete structure of the connector, refers to Fig. 2, and it includes the component 2 of first assembly 1 and second,
The component 2 of first assembly 1 and second is fastened and connected, and T-shaped cavity, the T-shaped chamber are formed after fastening
The top of body is inverted U, and bottom forms to be extended downwardly after the inside constriction in inverted U edge, T-shaped
Cavity up/down perforation.In order to main joist grafting, offer on the component 2 of first assembly 1 and second slotting
The slot that main joist is walked is formed after groove, fastening.
Because under normal circumstances, main joist is inverted T shaped keel, the top width of inverted T shaped keel is more than abdomen
Plate thickness, therefore, the width for being more than bottom with the width on the main joist neck top of main joist clamping.
The concrete structure of above-mentioned first assembly 1 is as shown in figure 3, first assembly 1 has inverted L shape body
Integral piece, the neck 102 that its top margin 101 is recessed to its plate face, this neck 102 is discontinuous card
Groove, its edge of top margin 101 have be bent to form downwards crotch 103 (this crotch be used for engage the second component
2 edge), its side 104 bends inwards the first boss 105 to be formed and be contacted with secondary joist flank,
The flank Access Division of the above section of first boss 105 formation secondary joist side, partly serves as secondary below
The web Access Division of keel side, offers two keyholes first on side of the first boss below 105
106, the first neck of main joist side 107 is offered on the side between two the first keyholes 106, by
It is usually inverted T shaped keel in main joist, the rib width at the top of it is thick compared with web, so main joist side the
The width on the top of one neck 107 is more than the width of bottom.
The concrete structure of above-mentioned second component 2 is as shown in figure 4, the second component 2 has the one of plate-like body
The card 202 of the 201 oriented anisopleual extensions of plate-like body at the top of body part, plate-like body, so card
Piece 202 be set for the eccentric relative to plate-like body (i.e. card 202 width on plate-like body not
Symmetrically), bend inwards to form second boss 203 in the middle part of plate-like body, the top of second boss 203
The flank Access Division of secondary joist opposite side is formed, secondary joist opposite side is formed at the bottom of second boss 203
Web Access Division, two the second keyholes 204 are offered in web Access Division, in two the second keyholes 204
Between side on offer the second neck of main joist opposite side 205, because main joist is usually inverted T shaped
Keel, the rib width at the top of it is thick compared with web, so the second neck of main joist opposite side 205 is also top
Width be more than bottom width.
Need 2 points of explanation：
(1) in the second component 2, the part of card 202 with the equidirectional of second boss 203 is narrower,
It is used for the clamping of neck 201 with first assembly 1, the card 202 with the opposite direction of second boss 203
Wider, gripping when it is used to fasten with the component 2 of first assembly 1 and second in part.
(2) in first assembly 1 keyhole position, lug boss position and main joist slot position with second group
Position on part 2 is corresponded.
Although disclosed embodiment is as above, its content is only to facilitate understand the present invention
Technical scheme and the embodiment that uses, be not intended to limit the present invention.Technology belonging to any present invention
Technical staff in field, can be with the premise of disclosed core technology scheme is not departed from
Any modification and change, but the protection domain that the present invention is limited are made in the form and details of implementation, still
The scope that must be limited by appended claims is defined.
