Description

End joint structure of structural member

The present invention relates to an end joint structure of a structural member; in particular, to an end joint structure of a structural member of a general building structure, which is constructed by a structural member having two vertical limbs and two horizontal limbs The joint plate is joined in a plugged manner.

As shown in Fig. 1, the cross-shaped bar member is fixed by butt welding, and the cross-shaped bar member is firstly aligned with the joint plate and then welded and fixed at the butt joint.

As shown in Fig. 2, the cross-shaped rods are fixed by angle steel welding, and the cross-shaped rods are first aligned with the joint plates, and then fixed with 4 angles of steel and welded.

As shown in Figure 3, the cross-shaped rods are fixed by angle steel or steel strips and bolts. The cross-shaped rods are first aligned with the joint plates, and then attached with angle steel or steel strips, and then fixed by bolts. .

When the cross-shaped bar shown in Fig. 1 is fixed by butt welding, ten The axial gap control of the glyph and the joint plate must be quite accurate. Therefore, the axial dimension accuracy requirements and installation accuracy of the cross bar are higher, and the manufacturing cost and installation time are also improved. Otherwise, the axial gap of the butt joint is too large. It is very difficult to complete the docking by the butt welding method. In this way, the fault tolerance space is small. If the axial length of the cross-shaped rod is too large, it cannot be installed, and it takes time to process the short or short.

When the cross-shaped bar member shown in Fig. 2 is fixed by angle steel welding, the axial gap control between the cross-shaped bar member and the joint plate may not be very precise, but the cross-shaped bar member and the joint plate must be aligned and fixed first, and then The four angle steels are welded together, and the welding amount on the spot is large. The angle steel cannot be welded and fixed with the cross-shaped rods at the factory. Although the axial clearance accuracy requirement can be reduced, the angled joint surfaces of the cross-shaped bar and the joint plate must also be aligned. Otherwise, the welding may be difficult when the angle steel cannot be attached, and the cross-section of the joint plate also needs to be with the cross-shaped bar. The same shape is the same as the cross and the same plate thickness. Because the angle steel is used for overlapping, the material usage is also high.

When the cross-shaped rods shown in Fig. 3 are fixed by angle steel or steel strips and bolts, they are fixed by bolts, but the bolt hole spacing is fixed. In order to avoid the problem that bolts cannot be installed on the holes, The dimensional accuracy requirements and mounting accuracy of the glyphs and the joint plates are relatively high, and the pitch spacing accuracy requirements of the bolts are also high. The cross section of the joint plates also needs to be the same as the cross-shaped bars and the same plate thickness, and more The angle steel or steel strip and the bolt lap joint material are also used in a relatively high amount.

The end joint structure of the structural rod of the present invention is completed by using a structural rod member and two sets of joint plates, wherein the structural rod member is composed of a long plate, and the end portion of the rod member is a section formed by the vertical limb and the horizontal limbs on both sides. The horizontal limbs on both sides have flat sides on both sides of the vertical limb The surface of the plate is formed with two notches having a width which is the thickness of the joint plate on both sides of the horizontal. The joint plate is used for joining the structural beam member and the structural beam member, and the two sets of the joint plate are coupled to the beam member of the structure, and the two sets of the joint plates maintain the interval between the vertical limb thicknesses of the structural members. Inserting the structural rod into the two sets of joint plates, so that the two sets of joint plates are respectively embedded in the two horizontal notches of the structural members, and the vertical members of the structural members are embedded in the interval between the two sets of the joint plates, and the joint plates are The horizontal limbs are in perpendicular contact with each other, and the joints of the structural members are completed by welding the joint edges of the joint plates and the vertical limbs of the structural members to the horizontal limbs.

The structural rod and the two sets of joint plates are joined by plugging or rotary plugging, the fault tolerance space is large, the axial length precision of the structural rods is not required to be high, the welding bead position construction space is good, and the welding time is low and the quality is high. There is no narrow working space problem, the average distribution of weld bead between the vertical limb and the horizontal limb and the joint plate is not easy to cause stress concentration, and can be greatly reduced when used in the buckling restraint for energy dissipation and shock absorption. The length required for the end joints increases the length of the energy dissipation core region.

In addition, the material thickness of the structural rod member and the two sets of joint plates need not be the same, as long as the two notches are matched with the thickness of the two sets of joint plates, and the two sets of joint plates are simple flat plate structures, and it is not necessary to use angle steel to connect the cross-shaped bars. When the joint plate is also required to use a cross-shaped section, and the thickness must be the same as the cross-shaped rod, otherwise the angle steel can not be flat surface joint.
