End joint structure of diagonal strut member

The present invention relates to an end joint structure of a diagonal strut member; in particular, to an end joint structure of a diagonal strut member of a general building structure, which is capable of simultaneously engaging a diagonal strut member by a joint plate having a recessed groove The vertical limbs are brought into close contact with the horizontal limbs and welded to complete the assembly.

As shown in Fig. 1, the double-strength joint plate of the conventional publication No. 200837253 is used, and the double-joint plate is used to sandwich the in-line plate-shaped ductile bracing, but the in-line toughness of the in-line toughness is insufficient, and the end portion is insufficient. The joint is prone to frustration or local frustration, and at least the cross-shaped section is more robust.

As shown in Fig. 2, the geometric connecting assembly and method for braced frame connections of the conventional US20130074440, between the energy dissipation diagonal strut members and the joint plate, are sandwiched by two sets of C-shaped steels with embedded grooves, and two sets of C-shaped Steel can be in complete contact with the energy dissipation diagonal strut. The disadvantage is that the C-shaped steel is more difficult to work with and more material. The energy-dissipating diagonal strut and the joint plate need to be connected through two sets of C-shaped steel to increase the material. Use, and the thickness of the joint plate needs to be the same as that of the energy dissipation diagonal strut, otherwise the C-shaped steel has In addition, the thickness of the joint plate can be different from the thickness of the energy dissipation diagonal strut.

As shown in Fig. 3, the conventional CN104234255A embedded buckling restraint support joint joint head, the energy dissipation diagonal strut member and the grooved joint plate surface are fully engageable, but the practical energy dissipation bracing It is very difficult to dock the vertical limbs of the rods and the joint plates on the construction site. It may be impossible to install due to the excessive length of the energy dissipation diagonal strut members, or the assembly gap is too short, so that the butt welding is performed. The amount is too large, so this method is an assembly method with extremely high precision.

The end joint structure of the diagonal strut member of the present invention is completed by using a diagonal strut member and a pair of joint plates, and the diagonal strut member is composed of a long plate, and the end portion of the rod member is composed of a vertical limb and two horizontal limbs. The cross-section, the joint plate is a flat plate structure, and the joint plate is provided with a groove corresponding to the horizontal limb thickness of the diagonal strut member, and the diagonal strut member is clamped by the pair of joint plates, and the horizontal limb of the diagonal strut member can be embedded in the groove of the joint plate The surface of the joint plate can be completely attached to the surface of the vertical limb, and the joint plate and the horizontal limb are fitted to each other in a perpendicular manner, and the joint plate can simultaneously contact the vertical limb and the horizontal limb, and the joint panel and the diagonal strut member The contact edge of the vertical limb and the horizontal limb is welded to complete the assembly of the end joint structure of the diagonal strut member.

a protruding plate is arranged at an end of the joint plate at the axial direction of the diagonal strut member, and the protruding plate is disposed at an axial position of the diagonal strut member and is parallel to the axial line of the diagonal strut member The protruding plate width is less than or equal to the height of the diagonal strut member, so that the protruding plate of the engaging plate can form the axis of the diagonal strut member at the vertical surface of the diagonal strut member. The contact edges of the line direction are available for soldering.

The edge of the groove of the joint plate is chamfered. When the vertical limb of the diagonal strut member is connected with the horizontal joint at a right angle, the weld bead will be raised, and the chamfer of the edge of the groove can avoid the diagonal support. The weld bead at the intersection of the vertical limb of the member and the horizontal limb at a right angle avoids interference so that the surface of the joint plate can be attached to the surface of the vertical limb.

Since the joint plate and the diagonal strut member have a margin of relative movement in the axial direction, even if there is an axial length error during the field assembly, sufficient contact edges are retained, and the assembly is easier to weld.

The protruding plate on the joint plate is integrally formed by the flat plate, thereby saving material. The protruding plate increases the axial parallel welding on the vertical limb of the diagonal strut member, so that the joint is stronger, and the diagonal strut is clamped by the pair of joint plates. In the way of the piece, the 1 pair of joint plates has better stiffness than the single set of joint plates.
