Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, the steel reinforced concrete column 100, the steel beam 200, and the connecting steel column 700 are included. In the invention, the section steel column in the prior art is changed into the reinforced concrete column 100, so that compared with the prior art, the consumption of a large amount of section steel is saved. The connecting steel column 700 is vertically arranged on the steel beam 200, and is further provided with an inclined rod 300 for ensuring the strength, the inclined rod 300 is arranged on the nodes of the reinforced concrete column 100 and the steel beam 200 and the nodes of the steel beam 200 and the connecting steel column 700 in a diagonal manner, each three layers of the inclined rods 300 are arranged in fig. 1, and the inclined rods 300 are inclined from top to bottom and far away from the reinforced concrete column 100.
Referring to fig. 1, the reinforced concrete column 100 and the steel beam 200 mainly include two nodes, including a vertical node a between the reinforced concrete column 100 and the steel beam 200, and a node B between the reinforced concrete column 100, the steel beam 200, and the diagonal member 300.
Vertical node between reinforced concrete column 100 and steel beam 200
Referring to fig. 2, the steel beam 200 is an H-shaped steel, and includes a top plate 210, a bottom plate 220, and ribs 230 therebetween. The rib 230 is provided with a reinforcing rib 260, and the reinforcing ribs 260 are perpendicular to the rib 230, the top plate 210 and the bottom plate 220. One end of the steel beam 200 is provided to the reinforced concrete column 100, and in the end of the steel beam 200, a plurality of pegs 400 are provided on the top surface and/or the bottom surface of the top plate 210 and/or both sides of the rib plate 230 and/or both sides of the reinforcing rib 260. And with reference to fig. 3, a plurality of holes 240 are provided on the top plate 210 and/or the bottom plate 220.
Referring to fig. 2, a steel plate 500 having a thickness of 24cm is provided under the end of the steel beam 200, the steel plate 500 is fixed to the base plate 220 by chemical bolts 600, and the steel plate 500 and the base plate 240 are parallel to each other and spaced apart by 300 cm. The chemical bolts 600 and the steel plate 500 are fixed by means of perforation welding.
Thus, after the concrete is poured, the studs 400 increase the engaging force of the steel beam 200 at the joints in the reinforced concrete column 100; the concrete can pass through the hole positions 240, and after solidification, an occlusion structure is formed, so that the firmness of the joints of the steel beam 200 is enhanced; the steel plate 500 can enlarge the overall height of the node of the steel beam 200, increase the torsion resistance and the load resistance of the steel beam 200 at the node, and greatly enhance the stability and the firmness of connection between the steel beam 200 and the reinforced concrete column 100.
Referring to fig. 4, the reinforced concrete column 100 includes reinforcing bars including vertical reinforcing bars 111, horizontal reinforcing bars 112, and stirrups 113. The vertical steel bars 111 partially pass through the reinforced concrete column 100 where the ends of the steel beams 200 do not pass through. Since a part of the vertical steel bars 111 is shielded by the steel beam 200 and cannot directly pass through the steel beam, the vertical rib 250 shown in fig. 2 is arranged at the node of the steel beam 200, and the vertical rib 250 is provided with two positions, which are respectively vertically arranged at the top of the top plate 210 and the bottom of the bottom plate 220. The ends of the vertical reinforcing bars 111 which cannot pass through directly can be welded on the vertical ribs 250 by a double-sided welding mode.
The stirrup 113 is an annular reinforcement surrounding the vertical reinforcement 111 on the periphery, however, it cannot be arranged at the node, and in order to make up for the absence of the stirrup 113 at the node, an oblique reinforcement 114 as shown in fig. 4 is arranged. The end of the diagonal reinforcement 114 is provided with a barb for hooking on the vertical reinforcement 111 located at the outermost periphery, and then the diagonal reinforcement 114 is wound around the node of the steel beam 200. Therefore, after the concrete is solidified, the support of the reinforcing steel bars cannot be lost at the joints.
Node among (II) reinforced concrete column 100, steel beam 200 and diagonal rod 300
With reference to fig. 5, the difference between the first step and the second step is that the reinforced concrete beam is provided with a second section steel 800 at the node, and the top of the second section steel 800 is welded on the bottom plate 220 at the node of the steel beam 200. The diagonal member 300 is also an H-shaped steel, and the bottom plate 320 and the top plate 310 thereof extend to the steel beam bottom plate 220 and the bottom of the second steel section 800, respectively, and are welded together.
The part of the inclined rod 300, from which the bottom plate 220 extends, shields the bottom of the section steel 800, and the steel plate 500 is arranged below the part and is also fixed by punching and welding with the chemical bolt 600.
The same as the first step, the second section steel 800 is also provided with a plurality of studs 400 and hole sites 240, and vertical steel bars 111, transverse steel bars 112 and stirrups 113 in the reinforced concrete. The arrangement of the vertical reinforcing bars 111 is slightly different from that of the vertical ribs 250. The second middle vertical rib 250 is provided on the extension plate of the bottom plate 220 of the diagonal bar 300.
In the invention, the reinforced concrete column 100 has low material cost and convenient construction, and saves section steel used by the steel column in the prior art. And the firmness of the connection joint between the reinforced steel beam 200 and the reinforced concrete column 100 is enhanced by the first reinforcing steel plate(s) and the second reinforcing steel plate(s), and the engagement force of the steel beam 200 joint between concrete is enhanced mainly through the steel plate 500, the reinforcing rib 260 and the stud 400, so that the joint has strong stability and firmness. Therefore, compared with the prior art, the invention saves the consumption of the section steel, is convenient for construction and is beneficial to accelerating the construction speed.
