Abstract
The present invention discloses a light steel paired joist connection structure and a connection method thereof, which belongs to a light steel joist for a building. The present invention is characterized in that a connecting piece is not connected between two paired joist bodies which are provided with grooves; a tenon is arranged at one end of one paired joist body, and clamping hooks which outward bulge are arranged on both lateral walls of the tenon; clamping grooves are respectively arranged on both lateral walls of one end of the other paired joist body, and the clamping grooves are matched with the clamping hooks on the tenon. A novel light steel paired joist connection structure is formed as long as the tenon of one paired joist body is inserted into a groove of another paired joist body until the clamping hooks on both of the two lateral walls of the tenon of the paired joist body are fit with the clamping grooves of both sides of the end of another paired joist body. The novel connection structure is used for the lengthening connection of light steel paired joists. The present invention has the advantages of high integral strength, convenient construction, good stability and low cost.
Description
Technical field
The present invention relates to syndeton of a kind of lightgage steel joist for building, especially light steel paired joist and attaching method thereof.
Background technology
The inventor once invented " automatic connecting light steel keel ", China Patent No.: 97231611.6, only solve main joist and do not wanted the problem of spreading annex, but because rider keel is different with the structure of main joist, if cancellation spreading annex is inconvenient, therefore the connection new construction of rider keel is failed to solve always, for with the light steel paired joist spreading, the syndeton of traditional light steel paired joist, remain between two rider keels, for example the connection between A auxiliary keel body and the B auxiliary keel body is by a special connector, these connector two ends insert in respectively in the groove of A auxiliary keel body and B auxiliary keel body end, reach the purpose of connection of two rider keels or spreading rider keel, but this connection has following deficiency: because the fit clearance between rider keel and the connector is big, the abutment is often very loose, the accuracy and the safety of spreading clinch are low, construction inconvenience is produced and managerial trouble link owing to this connector needs special production to increase again, and cost is also higher.
Summary of the invention
The problem to be solved in the present invention is the connector that will cancel between two rider keels, provides a kind of and can make direct-connected new syndeton and new method of attachment thereof between two light steel paired joists, makes bulk strength height, easy construction.
For addressing the above problem, solution of the present invention is: a kind of syndeton of light steel paired joist, comprise A auxiliary keel body with groove shape and with the identical B auxiliary keel body of its section structure, it is characterized in that: an end of described A auxiliary keel body is provided with the same head, is respectively equipped with outwards outstanding grab on this tenon two side; Be respectively equipped with draw-in groove outwards outstanding and that be complementary with grab on the above-mentioned tenon two side on the two side of described B auxiliary keel body one end.
Grab on the described tenon two side is extreme direction inclination outside tenon; The cross dimensions of described tenon is greater than the cross dimensions of above-mentioned A auxiliary keel body, and this tenon two side is recessed, and its top is plane.
Connection Step is as follows: get A auxiliary keel body and B auxiliary keel body, connect therebetween and do not need any connector, but the tenon of A auxiliary keel body one end is directly inserted in the groove of B auxiliary keel body one end, and continue deeply, till the draw-in groove on grab on this tenon two side and the two side, B rider keel one end matches, promptly finish fixedly connected between two rider keels.
After adopting technique scheme, the present invention has following beneficial effect against existing technologies:
Because the connector in the middle of the syndeton of this light steel paired joist has been cancelled, syndeton is simplified, links such as the production of connector and handling of goods and materials have been saved, easy construction, the efficient height, cost is low, as long as the tenon of an auxiliary keel body is directly inserted in the groove of another auxiliary keel body, grab on the A rider keel tenon two side and the draw-in groove on the B rider keel two side are matched, it is formed a fixed connection, the bulk strength that connects improves, tie point can not become flexible, safe and reliable, accuracy and good stability, no external force acts on B auxiliary keel body groove two side, then two auxiliary keel bodies cannot separate, thereby this connection structure connecting is simple, the method facility, quality is good.
Description of drawings
Fig. 1 is the syndeton of light steel paired joist of the present invention, the perspective view that A auxiliary keel body and B auxiliary keel body are connected as one.
Fig. 2 be the syndeton of light steel paired joist of the present invention be decomposed into or connect before the A auxiliary keel body and the perspective view of B auxiliary keel body.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
As depicted in figs. 1 and 2, the syndeton of light steel paired joist of the present invention comprises A auxiliary keel body 1 and the B auxiliary keel body 2 with groove shape, both section structures are identical, it is characterized in that: be provided with a tenon 3 (left part of A rider keel 1 in referring to Fig. 2) in an end of above-mentioned A auxiliary keel body 1, be respectively equipped with outwards outstanding grab 4 on the two side of this tenon 3, and tilt to the outer extreme direction of tenon 3, present embodiment is to be made by punching press, the cross dimensions of this tenon 3 is less than the cross dimensions of its auxiliary keel body 1, the two side of this tenon 3 is recessed, and its top is plane; Be respectively equipped with draw-in groove 5 on the two side of above-mentioned B auxiliary keel body 2 one ends, the grab 4 on this draw-in groove 5 and above-mentioned tenon 3 two sides is complementary.
The syndeton of above-mentioned light steel paired joist, its method of attachment step is: get two auxiliary keel bodies, for example A auxiliary keel body 1 and B auxiliary keel body 2, connection therebetween is without any need for connector, but directly insert the tenon 3 of A auxiliary keel body 1 one ends (present embodiment is a left end) in the groove 6 of B auxiliary keel body 2 one ends (present embodiment is a right-hand member), and continue deeply, till the draw-in groove 5 on grab on these tenon 3 two sides 4 and the two side, B auxiliary keel body 2 right part matches, promptly finish fixedly connected between two rider keels, become a kind of new Joining Structure of light steel paired joist.
Claims (2)
1. the syndeton of a light steel paired joist, comprise A auxiliary keel body with groove shape and with the identical B auxiliary keel body of its section structure, it is characterized in that: an end of described A rider keel is provided with a tenon, is respectively equipped with outwards outstanding grab on this tenon two side; Be respectively equipped with on the two side of described B auxiliary keel body one end with above-mentioned tenon two side on the draw-in groove that is complementary of grab; The grab of described tenon two side is to the tenon outer end to tilt respectively; The cross dimensions of described tenon is less than the cross dimensions of above-mentioned A auxiliary keel body, and this tenon two side is recessed, and its top is plane.
