Abstract

The utility model relates to a butterfly self-lock connecting fastener which can be used in a knock-down wall type framework node connecting fastener, comprising a fastener body, and two fastener wings which are parallel with each other, are arranged at the two ends of the fastener body and have self-lock shoulders, the surface, on which the fastener wing is connected with the fastener body, is at the same plane of the fastener body, and through holes are arranged on the surface. The butterfly self-lock connecting fastener naturally finishes the fastening work with a vertical post by only utilizing the process that screws are fixedly fastened with a beam, and an anti-deforming moment arm of the node can give full play in the event that the physical spaces of the beam and the vertical post are limited. The utility model can fully give play in the strength of section steel and the butterfly self-lock connecting fastener, and can reduce the infection on the strength of the node from the lacking fastening strength of the screw; furthermore, the utility model has simple structure.

Description

The butterfly self-lock connecting clamp

Technical field

The utility model relates to the mullion of a kind of dismantled and assembled, skeleton partition wall (or claiming partition system) and the cross linkage of crossbeam.Cross section geometry one timing at mullion and crossbeam can realize its coupling stiffness and intensity to greatest extent.

Background technology

At present, known dismantled and assembled, skeleton partition wall (or claiming partition system) structure is to make skeleton by mullion and crossbeam, be inlaid with plaque and door and window on this structure, so the strength and stiffness of skeleton has determined the strength and stiffness of this system to a certain extent.Because the characteristic of dismantled and assembled, skeleton partition wall itself has determined mullion and crossbeam must disconnect at the crosspoint top rail, and is connected with screw by connector.But the space limits that to make that connector can't be done very big, causes tie point to become the weak spot of this structure, and whole system is rocked greatly.The key that throws into question is a little less than node strength and the rigidity, can't make the strength and stiffness of mullion and crossbeam itself obtain performance.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of butterfly self-lock connecting clamp that makes full use of arm of force effect on limited three dimensions is provided.

Butterfly self-lock connecting clamp described in the utility model comprises the card main body, is respectively arranged with two card wings with self-locking shoulder at the two ends of card main body, and each blocks one side that the wing is connected with the card main body and blocks main body at grade, has through hole on it.

The mutual distance of the self-locking shoulder at described card main body two ends is determined according to the width of the mullion that will install, determines according to the width of the crossbeam that will connect in the distance that the self-locking shoulder of the same end of card main body is mutual.

The described card wing has the self-locking grooves that is shaped as a shape, and its trench bottom is positioned at same plane with the card main body.

The described card wing is that circular arc excessively is connected with the two ends of the junction of card main body.

Butterfly self-lock connecting clamp described in the utility model has utilized self-lock mechanism, makes its node strength and rigidity can reach desirable, and has reduced the influence that coupling stiffness and intensity are subjected to screw intensity.Beneficial effect is, the butterfly self-lock connecting clamp only utilizes the fastening work of having finished naturally in the fastening process of screw and crossbeam with mullion, and the resistance to deformation arm of force of node has been issued in the condition that limits crossbeam and mullion geometric space and gives full play to.Can give full play to the intensity of section bar and butterfly self-lock connecting clamp itself, and reduce the influence that the fastening strength deficiency of coping screw own causes node strength, simple in structure.When using the inside groove of the screw-in of the self-locking grooves from Connection Card both sides crossbeam, make it to form self-locking grooves and improved tightness with Connection Card from the merit screw.The connection angle of Connection Card and the node bending resistance arm of force according to the self-locking shoulder decision of Connection Card, have made full use of limited structure space fully.

The utility model is described in further detail below in conjunction with accompanying drawing and instantiation.

Fig. 2 is the structure chart that the butterfly self-lock connecting clamp connects horizontal, vertical beam;

Fig. 3 is the lateral view of Fig. 2;

Fig. 4 is butterfly self-lock connecting clamp and mullion and crossbeam locking process schematic diagram.

The specific embodiment

Referring to Fig. 1, butterfly self-lock connecting clamp 3 described in the utility model comprises card main body 4, is respectively arranged with at the two ends of card main body 4 to have two card wings 5 self-locking shoulder 6, that be parallel to each other, each blocks the wing and the one side that is connected of card main body 4 and blocks main body 4 at grade, has through hole on it.Described self-locking shoulder 6 be with card wing plate that card main body 4 two ends are connected on protruding opposite flank, it both played the chucking effect to mullion 1, again crossbeam was played pressuring action.

The self-locking at described card main body 4 two ends is takeed on 6 mutual distance L and is determined according to the width of the mullion 1 that will install, and it is definite according to the width of the crossbeam 2 that will connect to take on 6 mutual distances in the self-locking of card main body 4 same ends.

The described card wing 5 has the self-locking grooves 7 that is shaped as a shape, and its trench bottom is positioned at same plane with card main body 4.For making things convenient for crossbeam to insert self-locking grooves, between two self-locking grooves bottom land planes of crossbeam side and card main body 4 the same sides certain interval is arranged.

The described card wing 5 is that circular arc excessively is connected with the two ends of the junction of card main body 4.

Referring to Fig. 2 and Fig. 3, during installation, mullion 1 is placed on the card main body 4, and insert in the self-locking grooves of the card wing 5 on the both sides of the crossbeam 2 of two disconnections, with self-tapping screw Connection Card 3 is connected with crossbeam 2, at the mullion 1 and the another side of crossbeam 2 Connection Card 3 is installed equally again.

Referring to Fig. 4, the inner of the self-locking grooves 7 of each card wing has self-locking shoulder 6, because the distance between the bottom land plane of two self-locking grooves that are parallel to each other is greater than the width of the crossbeam that is connected, there is a gap bottom land plane and crossbeam side, with the fastening process of crossbeam in the outer end of self-locking grooves draw close to crossbeam, two self-lockings shoulders that drive both sides clamp to mullion.Than can several times clamping mullions to ten fastening pressures times over screw, what make it not only to have finished crossbeam laterally connects simultaneously but also has finished being connected of crossbeam and mullion according to the card length of the wing and self-locking shoulder breadth degree.Two of its characteristics are: the butterfly self-lock connecting clamp was finished by self-locking with being connected also of crossbeam, when if the two sides of crossbeam also are flute profile, make it outwards to extrude when time in the grooved that screws in the crossbeam section bar with self-tapping screw from self-locking grooves, with the mutual jam-packed of the self-locking grooves of Connection Card both sides, strengthened the tightness of screw.Three of its characteristics are: the butterfly self-lock connecting clamp is to control four self-locking shoulders respectively by four dish wings, can make the abundant balance of strength, make its connection angle fixed according to the self-locking shoulder of Connection Card fully, and made full use of arm of force effect, eliminated the weak problem of node of structure from three-D space structure.
