A kind of steel building brace summer
Technical field
The utility model relates to a kind of steel building brace summer.
Background technology
Steel building is promoted fast and rapidly with its easy construction, brace summer intensity used in steel building in prior art is lower, easy distortion, and current brace summer generally comprises an i iron and two channel-section steels, i iron and channel-section steel are fixed by bolt, bolt protrudes from i iron surface, makes i iron surface irregularity, thus affects the use of this brace summer.
Utility model content
Technical problem to be solved in the utility model is, provides the steel building brace summer that a kind of intensity is higher, be not easy distortion, i iron surfacing.
For solving the problems of the technologies described above, the steel building brace summer that the utility model provides, it comprises an i iron and two channel-section steels, described i iron comprises two the first plate bodys paralleled and the second plate body be vertically connected between two the first plate bodys, described each channel-section steel includes the 3rd plate body and is vertically connected on two the 4th plate bodys at the 3rd plate body two ends respectively, the corner of the outside of belly of two channel-section steels is provided with the gripper shoe of L shape, the perpendicular dual-side of the gripper shoe of L shape is welded and fixed with the first plate body and the second plate body respectively, the outside of belly of two the 3rd plate bodys is provided with the arc fin of the some articles of extensions of the length directions along the 3rd plate body, the position being positioned at the second plate body both sides of i iron forms a rectangular recess respectively, two channel-section steels are separately positioned in two rectangular recess, the back side of two the 3rd plate bodys fits with two surfaces of the second plate body respectively, the back side of four the 4th plate bodys fits with the inner surface of the first corresponding plate body respectively, four the 4th plate bodys are respectively arranged with one first through hole, two the first plate bodys are provided with altogether the ladder hole that four difference, four the first through hole one_to_one corresponding are arranged, each ladder hole includes and is connected and larger the second through hole of a diameter of coaxial line and the less third through-hole of a diameter, being connected of all equal with the first corresponding through-hole diameter and the coaxial line of third through-hole in each ladder hole.
As preferably, the external surface of two described the first plate bodys is provided with a zinc coat.
After adopting above structure, the utility model compared with prior art, has following advantage:
In the utility model, the 3rd plate body is provided with arc fin, and arc fin plays the effect of reinforcing rib, simultaneously, the gripper shoe of L shape is set in the corner of the outside of belly of channel-section steel, makes this brace summer intensity higher, be not easy distortion, and, first plate body arranges ladder hole, and when bolt is located in after in ladder hole and corresponding first through hole, the head of bolt is placed in the second through hole, so just make the head of bolt concordant with the surface of the first plate body, make i iron surfacing.
Accompanying drawing explanation
Fig. 1 is the cross sectional representation of a kind of steel building brace summer of the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, the utility model steel building brace summer comprises an i iron and two channel-section steels, described i iron comprises two the first plate bodys 1 paralleled and the second plate body 2 be vertically connected between two the first plate bodys 1, described each channel-section steel includes the 3rd plate body 3 and is vertically connected on two the 4th plate bodys 4 at the 3rd plate body 3 two ends respectively, the corner of the outside of belly of two channel-section steels is provided with the gripper shoe 8 of L shape, the perpendicular dual-side of the gripper shoe 8 of L shape is welded and fixed with the first plate body 1 and the second plate body 2 respectively, the outside of belly of two the 3rd plate bodys 3 is provided with the arc fin 7 of the some articles of extensions of the length directions along the 3rd plate body 3, the position being positioned at the second plate body 2 both sides of i iron forms a rectangular recess 5 respectively, two channel-section steels are separately positioned in two rectangular recess 5, the back side of two the 3rd plate bodys 3 fits with two surfaces of the second plate body 2 respectively, the back side of four the 4th plate bodys 4 fits with the inner surface of the first corresponding plate body 1 respectively, four the 4th plate bodys 4 are respectively arranged with one first through hole 401, two the first plate bodys 1 are provided with altogether the ladder hole that four difference, four the first through hole 401 one_to_one corresponding are arranged, each ladder hole includes and is connected and larger the second through hole 601 of a diameter of coaxial line and the less third through-hole 602 of a diameter, third through-hole 602 in each ladder hole is all with the first corresponding through hole 401 equal diameters and being connected of coaxial line, in the present embodiment, first plate body 1 arranges ladder hole, when bolt is located in after in ladder hole and corresponding first through hole 401, the head of bolt is placed in the second through hole 601, so just make the head of bolt concordant with the surface of the first plate body 1, make i iron surfacing, and, 3rd plate body 3 is provided with arc fin 7, arc fin 7 plays the effect of reinforcing rib, simultaneously, the gripper shoe 8 of L shape is set in the corner of the outside of belly of channel-section steel, make this brace summer intensity higher, be not easy distortion.
The external surface of two described the first plate bodys 1 is provided with a zinc coat, and zinc coat plays corrosion-resisting function, makes the utility model be not easy be corroded and damage, makes application life longer.
Below only apply preferably example with regard to the utility model and made explanation, but can not be interpreted as it is limitations on claims, structure of the present utility model can have other to change, and is not limited to said structure.In a word, all various changes done in the protection domain of independent claims of the present utility model are all in protection domain of the present utility model.
