Description

Pre-bonded diagonal strut

The invention relates to a diagonal strut member which is pre-joined by a joint plate; in particular, a pre-bonded 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 limb of the end section is brought into close contact with the horizontal limb, so that the joint plate can be temporarily fixed to the diagonal strut member in advance and has the function of axially telescopically adjusting the length.

As shown in Fig. 1, the slotted frustum beam support device of the conventional I341347 is provided with a groove on the long plate-shaped main body, so that the joint plate can be inserted into the groove and generated with the long plate-shaped main body. Contacting to provide the welding part, in addition to reducing the length of the joint portion and increasing the length of the deformation energy-dissipating portion, the joint assembly is quick and convenient, especially when the joint plate is pre-welded to the beam-column rod member fixed on the structure, It is fastened by oblique insertion and does not require precise assembly positioning.

However, when the joint plate is pre-welded to the beam-column rod member fixed on the structure, the joint position of the joint plate at the two ends of the diagonal line of the beam-column frame is respectively installed, and the groove axis of the groove-type buckling beam support device is fixed. Need to match the linear accuracy In other cases, one end of the groove can be inserted into the joint plate, and the other end of the lateral position is a little bit stuck and the edge can not be inserted to complete the installation.

In addition, in the long plate-shaped main body of the slotted frustum beam support device of I341347, if the long plates perpendicular to each other are welded by the fillet, the long plate is not required to be grooved, and the fillet is welded or opened. In the groove welding, the weld bead will be convex, but the long plate at the end groove is flat on the edge of the groove, so the fillet welding cannot be used, and the slot welding method must be used, so that the automatic welding machine is assembled during welding. It is impossible to complete the welding at one time. The welding at the vertical intersection of the grooved long plates at both ends needs to be treated separately, and the weld bead must not have protrusions, otherwise it will hinder the insertion of the joint plate and get stuck, so it is necessary to grind the convex portion of the weld bead. Make sure that there is no bulge, so it takes more time.

The pre-bonded diagonal strut member of the present invention is a rod member whose axial length is retractable and adjustable, and can be matched with the situation when the diagonal length of the beam-column frame and the design value are large when the field installation accuracy is not good. Adjustments make installation easier and faster.

In the pre-bonded diagonal strut member of the present invention, the joint plate and the diagonal strut member are combined by the groove, and only the relative axial movement between the joint plate and the diagonal strut member is generated, so that only the assembly and fixing are required. With the length of the field installation, the position of the axial direction is adjusted and then fixed by welding, and the assembly is faster.

When the joint plate is pre-bonded to the diagonal strut member, when the joint plate is first fixed to the beam-column frame, there may be an excessive cross between the two sets of the joint plates on the diagonal line. The error causes the end of the diagonal strut to be stuck to the joint plate, and the joint plate cannot be inserted to complete the installation.

In the diagonal strut member in which the joint plate of the present invention is pre-bonded, after the joint plate and the diagonal strut member are combined by the groove, the whole set can be hoisted to the beam-column rod member on the structure, and then loosened. The temporary fixing device can adjust the length and then lock the temporary fixing device, and then the welding can be conveniently fixed. Since only the axial direction has the problem of positioning accuracy, the axial positioning does not affect the transmission of the axial force, so the assembly precision is easier to control without affecting the structural behavior.

In the diagonal strut member in which the joint plate of the present invention is pre-joined, the diagonal strut member is composed of a long plate, and the end portion has a cross section formed by a vertical joint of the vertical limb and the horizontal limb, and at least two sets of vertical limbs are respectively disposed at a horizontal level. The upper and lower plane positions of the limbs are maintained at intervals of the thickness of the joint plates between the two sets of vertical limbs, and the joint plate is provided with a groove of the horizontal limb thickness of the diagonal strut member, and the horizontal limb of the diagonal strut member is embedded in the groove of the joint plate. And the joint plate is embedded in the interval between the two sets of vertical limbs, the surface of the joint plate can be attached to the surface of the vertical limb of the diagonal strut member, and the joint plate can simultaneously be attached to the vertical limb and the horizontal limb of the diagonal strut member. The contact plate enables the joint plate to be temporarily fixed to the diagonal strut member in advance and has the function of axially telescopically adjusting the length. After the joint plate is positioned, the joint between the vertical plate and the horizontal limb of the joint plate and the diagonal strut member is The contact edge is welded and fixed, and the assembly of the pre-bonded diagonal strut member of the joint plate is completed.
