Abstract
The utility model discloses a clamp type keel, which belongs to the technical field of building materials and is composed of two side plates and a base plate. A semi-circular groove is arrange at the upper end of a first side plate, a reversed hook structure composed of an inclined face and an arc is arranged on one side of the semi-circular groove, and a symmetrical structure is arranged on the other side of the semi-circular groove. Holes are evenly distributed on the side plates, the structure of a second side plate is the same with the structure of the first side plate, and the first side plate, the second side plate and the base plate are connected to form a rectangle with the cross section provided with an opening. The cross section of an auxiliary keel is a rectangle with an opening. The opening end portion of the cross section of the auxiliary keel is provided with an extending portion which is clamped on reversed hook structures of the side plates of a main keel. The clamp type keel has the advantages that the structures of the main keel and the auxiliary keel are reasonable and connection of the main keel and the auxiliary keel are convenient and firm.
Description
Technical field
The utility model relates to a kind of cassette keel, belongs to building material technical field.
Background technology
Existing main joist and rider keel structure are comparatively complicated, and main joist is connected inconvenient with rider keel.
Summary of the invention
In view of the above problems, the purpose of the utility model is to provide a kind of cassette keel.
A kind of cassette keel of the utility model; Comprise: main joist and rider keel; Main joist is that two side plates (first side plate and second side plate) and base plate are formed; There is semicircle groove the upper end of first side plate, and the overhead structure of being made up of inclined-plane and circular arc in a side of semicircle groove has symmetrical structure at the opposite side of semicircle groove; Be uniformly distributed with porosely on the side plate, the structure of second side plate is identical with first side plate, and first side plate and second side plate and base plate are connected to form the rectangle that the cross section is an opening; The rider keel cross section is the rectangle of opening; Open end in the rider keel cross section has extension, and the open end extension in rider keel cross section is stuck on the overhead structure of side plate of main joist.
The advantage of the utility model: main joist and rider keel are rational in infrastructure, and main joist and rider keel are easy to connect and firm.
Description of drawings
When combining accompanying drawing to consider; Through with reference to following detailed, can more completely understand the utility model better and learn wherein many attendant advantages easily, but accompanying drawing described herein is used to provide the further understanding to the utility model; Constitute the part of the utility model; Illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model, wherein:
Fig. 1 is the side plate sketch map of the utility model;
Fig. 2 is the principal character structural representation of the side plate of the utility model;
Fig. 3 is that the main joist of the utility model is connected sketch map with rider keel;
Fig. 4 is the main joist structural representation of the utility model.
The specific embodiment
Referring to figs. 1 through Fig. 4 the embodiment of the utility model is described.
Obviously, the many modifications made based on the aim of the utility model of those skilled in the art and the variation protection domain that belongs to the utility model.
A kind of cassette keel of the utility model; Comprise: main joist 1 and rider keel 6; Main joist 1 is that two side plates (first side plate 8 and second side plate 9) and base plate 7 are formed; There is semicircle groove 3 upper end of first side plate 8, and the overhead structure of being made up of inclined-plane 5 and circular arc 4 in a side of semicircle groove 3 has symmetrical structure at the opposite side of semicircle groove 3; The structure that is uniformly distributed with porose 2, the second side plates 9 on the side plate (first side plate 8 and second side plate 9) is identical with first side plate 8, and first side plate 8 and second side plate 9 are connected to form the rectangle that the cross section is an opening with base plate 7; Rider keel 6 cross sections are the rectangle of opening; Open end in rider keel 6 cross sections has extension, and the open end extension in rider keel 6 cross sections is stuck on the overhead structure of side plate of main joist 1.
Be uniformly distributed with porose on the base plate 7.
As stated, the embodiment of the utility model has been carried out explanation at length, but as long as break away from the inventive point and the effect of the utility model in fact a lot of distortion can not arranged, this will be readily apparent to persons skilled in the art.Therefore, such variation also all is included within the protection domain of the utility model.
