Abstract
The invention provides an I-beam with dovetail teeth, an I-beam with dovetail grooves, and an I-beam combination. The I-beam with the dovetail teeth comprises an upper wing plate, a web and a lower wing plate, wherein the upper wing plate is parallel with the lower wing plate, the web is perpendicularly connected between the upper wing plate and the lower wing plate, and the two edges of the upper wing plate and the two edges of the lower wing plate comprise the dovetail teeth respectively. The I-beam combination comprises the I-beam with the dovetail teeth and the I-beam with the dovetail grooves, wherein the dovetail teeth are clamped in the dovetail grooves of the I-beam with the dovetail grooves to form the stable I-beam combination. The I-beam combination can bear cross beams of large places, so that the steel frame structure in a project is firm and stable.
Description
Technical field
The present invention relates to I-steel, relate in particular to a kind of band dovetail tooth I-steel, band dovetail groove I-steel and I steel composite.
Background technique
I-steel also claims girder steel, is that cross section is I-shaped rectangular steel.I-steel is widely used in various building structure, bridge, vehicle, support, machinery etc.I-steel divides common I-steel and lightweight I-beam, three kinds of H shaped steel.I-steel is widely used in various building structure, bridge, vehicle, support, machinery etc.The edge of a wing of common I-steel and lightweight I-beam by root to attenuation gradually on limit, there is certain angle, the model of common I-steel and lightweight I-beam is to represent with the Arabic numerals of the high cms of its waist, web, edge of a wing thickness its specifications different from flange width represent with the milli number of waist wide (the b) × waist of high (h) × leg thick (d), as " general work 160 × 88 × 6 ", represent that waist high is 160 millimeters, leg is wide is 88 millimeters, and waist is thick is the common I-steel of 6 millimeters./ " light industry 160 × 81 × 5 ", represents that waist high is 160 millimeters, and leg is wide is 81 millimeters, and waist is thick is the lightweight I-beam of 5 millimeters.The specification of common I-steel also available model represents, model represents the cms that waist is high, as general work 16#.The high identical I-steel of waist, wide thick with waist if any several different legs, need add below a b c in model and be distinguished, as general work 32#a, 32#b, 32#c etc.The specification of the common I-steel of hot rolling is 10-63#.The common I-steel specification of hot rolling through the supply of both sides of supply and demand agreement is 12-55#.
Therefore I-steel cross section is symmetrical can fine Bending stress.So do crossbeam with I-steel in common engineering.
Summary of the invention
The invention provides a kind of I-steel and combination thereof, using as the large local crossbeam of load-bearing weight.
For this reason, the invention provides a kind of band dovetail tooth I-steel, comprise upper flange, web and lower wing plate, described upper flange is parallel with described lower wing plate, and described web is vertically connected between described upper flange and described lower wing plate; The two edges of described upper flange and described lower wing plate all include respectively dovetail tooth.
The present invention is optional, and described web and described upper flange joint are formed with side of body portion, and described web and described lower wing plate joint are formed with lower side of body portion.
The present invention also provides a kind of band dovetail groove I-steel, comprises upper flange, web and lower wing plate, and described upper flange is parallel with described lower wing plate, and described web is vertically connected between described upper flange and described lower wing plate; The recessed dovetail groove that is formed with of inward at both ends of described upper flange and described lower wing plate.
The present invention is optional, and described web and described upper flange joint are formed with side of body portion, and described web and described lower wing plate joint are formed with lower side of body portion.
The present invention also provides a kind of I steel composite, comprise as above with dovetail tooth I-steel and the band dovetail groove I-steel of the above, wherein, describedly with dovetail tooth I-steel described, with dovetail tooth, snap in describedly with in the described dovetail groove in dovetail groove I-steel, form described I steel composite.
Compared with prior art, the present invention has the following advantages:
I steel composite provided by the present invention includes band dovetail tooth I-steel and band dovetail groove I-steel, wherein said with dovetail tooth, snap in described with in the described dovetail groove in dovetail groove I-steel, form stable I steel composite, can, for the large local crossbeam of load-bearing, make the steel frame construction firm stable in engineering.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of embodiment of the present invention band dovetail tooth I-steel;
Fig. 2 is the schematic diagram of embodiment of the present invention band dovetail groove I-steel;
Fig. 3 is the schematic diagram of embodiment of the present invention I steel composite.
Embodiment
Please refer to Fig. 1, Fig. 1 is the schematic diagram of embodiment of the present invention band dovetail tooth I-steel.As can be seen from Figure 1, the present embodiment band dovetail tooth I-steel includes upper flange 1, web 2 and lower wing plate 3, and described upper flange 1 is parallel with described lower wing plate 3, and described web 2 is vertically connected between described upper flange 1 and described lower wing plate 3.The edges at two ends of described upper flange 1 is respectively with two upper dovetail teeth 11, and the edges at two ends of described lower wing plate 3 all includes respectively two lower dovetail teeth 31, and whole I-steel is symplex structure.And can also see in Fig. 1, in the present embodiment, the described described web with dovetail tooth I-steel 2 and described upper flange 1 joint are formed with upper side of body portion 12, described web 2 and described lower wing plate 3 joints are formed with lower side of body portion 32.Arranging of side of body portion 12 and 32 can make the ability of I-steel Bending stronger.
Please refer to Fig. 2, Fig. 2 is the schematic diagram of embodiment of the present invention band dovetail groove I-steel.As can be seen from Figure 2, the present embodiment band dovetail tooth I-steel includes upper flange 4, web 5 and lower wing plate 6, and described upper flange 4 is parallel with described lower wing plate 6, and described web 5 is vertically connected between described upper flange 4 and described lower wing plate 6.The inward at both ends of described upper flange 4 is the recessed dovetail groove 40 that is formed with respectively, and the inward at both ends of described lower wing plate 6 is recessed into and is formed with respectively lower dovetail groove 60, and whole I-steel is symplex structure.Although do not show in Fig. 2, but band dovetail groove I-steel provided by the present invention can be formed with side of body portion at described web 5 with described upper flange 4 joints, in described web 5 and described lower wing plate 6 joints, can be formed with lower side of body portion, form side of body portion and can make the ability of I-steel Bending stronger.
