Description
Technical field
The utility model relates to a kind of keel, is specifically related to a kind of high strength clamping keel.
Background technology
In building decoration engineering, be used for bearing the stress frame of decorated wall surface, cylinder, bottom surface, door and window and ceiling finish material quality, be called decoration framework, also can be called keel, the Main Function of keel be fix, make, load-bearing.The kind of keel has a lot, according to the difference making material, can be divided into rough ground, lightgage steel joist, aluminium alloy joist, steel joist etc.; Divide according to use position, channel, straight wall keel, floor file keel can be divided into again and hang keel.
Lightgage steel joist, it is a kind of novel constructional materials, along with the development of China's modernization construction, lightgage steel joist is widely used in the places such as hotel, departure lounge, Che Yunzhan, station, playground, market, factory, office building, old building remodeling, interior decoration setting, ceiling.Steel joist suspended ceiling have lightweight, intensity is high, adapt to the effects such as waterproof, shockproof, dust-proof, sound insulation, sound-absorbing, constant temperature, also has the advantages such as duration short, easy construction simultaneously.In the construction technologies such as traditional light steel keel partition and furred ceiling, the component and fittings such as keel are connected with keel, junction box and spool and keel fixing etc., adopts the modes such as self-plugging rivet, tapping screw or special fastener to carry out usually, expense of not only taking a lot of work is expected, once have a power failure, just cannot construct, affect the duration.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of high strength clamping keel, and these keel not only bonding strength are high, not easily come off, and can independently dock, and do not need extra instrument to assist, docking operation facilitates easy-to-use.
Following scheme is adopted in order to reach above-mentioned technical purpose the utility model:
A kind of high strength clamping keel, comprise cylindric keel, on the lateral surface of described cylindric keel, circumference is evenly equipped with groove, the two ends of keel are provided with plug and jack, described plug is solid cylinder, uniform at least two endoporus of circumference on the external surface of plug, be provided with the positioning head wanting with hole size to coordinate in endoporus, described positioning head is fixed in endoporus through elastic mechanism; Described jack is the sleeve of hollow, and on the sidewall of jack, circumference is evenly equipped with the locating hole consistent with described interior hole number, and the size of locating hole and the matching size of positioning head close.
Pass through technique scheme, coordinate at the two ends of keel and be provided with plug and jack, during use by the plug of adjacent keel and jack with the use of, because the positioning head in plug endoporus is fixed in endoporus through elastic mechanism, now positioning head is depressed into the height concordant with the inwall of jack when therefore using, plug can be inserted in jack smoothly, then twist plug gently, when positioning head is screwed to the angle of locating hole, under the control of elastic mechanism, positioning head ejects, be connected together firmly by two keel, the elastic mechanism used in the technical program can be spring or other elastomeric material, require that the connection of elastic mechanism and endoporus and positioning head is tight, elastic deformation is good.In order to adapt to the user demand of light joist, the lateral surface of keel is provided with the uniform groove of circumference, just can well controls the weight of keel according to the difference of depth of groove, easy to use with construction, this symmetrical structure also ensure that keel uniform force, with the working strength of keel simultaneously.
Further, plug described in the utility model and locating hole are also provided with the pin-and-hole matched, in jack, are provided with alignment pin.
Further, positioning head described in the utility model is any one in cuboid, cylinder or triangular prism.
Further, on the lateral surface of cylindric keel described in the utility model, circumference is evenly equipped with groove, and the degree of depth of groove is not less than 1/8th of keel internal diameter.
The beneficial effects of the utility model are: 1. the utility model provides a kind of high strength clamping keel, the two ends cooperation of keel is provided with plug and jack, plug is provided with positioning head, positioning head is connected with elastic mechanism, in the endoporus that can submerge in plug, or eject from endoporus, therefore, when adjacent Keel butt joint, under the control of elastic mechanism, positioning head ejects, and two keel can be connected together firmly, the utility model structure is simply easy for installation, brings great convenience to constructor.2, in order to adapt to the user demand of light joist, the lateral surface of keel is provided with the groove that circumference is uniform, the weight of keel just can well be controlled according to the difference of depth of groove, easy to use with construction, this symmetrical structure also ensure that keel uniform force, with the working strength of keel simultaneously.

Fig. 2 is the structural representation in the utility model A-A cross section.
Fig. 3 is the structural representation in the utility model B-B cross section.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, Figure 2 and Figure 3, a kind of high strength clamping keel, comprise cylindric keel, on the lateral surface of described cylindric keel, circumference is evenly equipped with 4 grooves 3, and the degree of depth of groove is 1/8th of keel internal diameter, and the two ends of keel are provided with plug 1 and jack 2, described plug 1 is solid cylinder, uniform four endoporus 4 of circumference on the external surface of plug, be provided with the positioning head 5 wanting with hole size to coordinate in endoporus 4, described positioning head 5 is fixed in endoporus 4 through elastic mechanism 7; Described jack 2 is the sleeve of hollow, on the sidewall of jack 2, circumference is evenly equipped with the locating hole 6 consistent with described endoporus 4 quantity, the size of locating hole 6 and the matching size of positioning head 5 close, plug 1 and jack 2 can also arrange the pin-and-hole matched, alignment pin is provided with in pin-and-hole, after the keel that clamping is good adjacent, as inserting alignment pin in pin-and-hole or two keel can more firmly dock by other securing member.
During use, by the plug of adjacent keel and jack with the use of, because the positioning head 5 in endoporus 4 is fixed in endoporus through elastic mechanism 9, now positioning head 5 is depressed into the height concordant with the inwall of jack when therefore using, plug 1 can be inserted in jack 2 smoothly, then twist plug 1 gently, when positioning head 5 is screwed to the angle of locating hole 6, under the control of elastic mechanism 9, positioning head 5 ejects, be connected together firmly by two keel, finally alignment pin can also be used, through the pin-and-hole that plug-socket is equipped with, the keel that two dock are fixed together further.
