Description

Hinged diagonal strut

The present invention relates to an articulated diagonal strut member; and more particularly to an articulated diagonal strut member of a general building structure, which is connected in an interlaced manner by a shaft hole plate having a shaft hole, and can simultaneously be used with the diagonal strut member The vertical limb of the end section is brought into close contact with the horizontal limb to complete the assembly by welding.

As shown in the figure above, the M453702 pin-type buckling beam support device is provided with a pin-receiving hole for the buckling beam support device, and the pin-joining hole uses the carrier plate to strengthen the bearing strength of the circular hole. It is a commonly used reinforcement method for connecting the ends of the general steel structural members in an articulated manner, that is, two pieces of washers are welded on both sides of the steel plate opening, but for the cross-shaped members, only the vertical plate is strengthened. At the position of the hole, the horizontal plate is not directly connected with the pin hole, the transmission of the force is transmitted to the vertical plate by the pin hole, and the vertical plate is redistributed to the horizontal plate, that is, between the pin hole and the cross section Only the one-shaped cross-section of the vertical plate has the weakest minimum strength and the stress is concentrated at the one-shaped cross-section with a small cross-sectional area.

As shown in the figure below in Figure 1, even though the M453702 pin-type frustration beam support device proposes the use of a reinforced plate, the reinforced plate is only connected to the cross section. The horizontal plate is spaced apart from the vertical plate of the cross-shaped section, and is still in a manner of dispersing the force. The force is not integrated, the stress concentration is likely to occur at the joint between the reinforcing plate and the horizontal plate, and the total lateral direction of the pin connection hole is also Larger width, need to use a larger horizontal joint space, the shape of the multi-piece partition also makes the structure more complicated, regardless of welding, or surface anti-corrosion treatment, or energy dissipation bracing surface and the surrounding material isolation treatment are more susceptible to A plurality of narrow spaces spaced vertically between the sheets result in difficulties or flaws in the application.

The hinged diagonal strut member of the invention is connected by the horizontal limbs of the shaft hole plate and the diagonal strut member in an interlaced manner, and the shaft hole plate can be simultaneously connected to the vertical limb and the horizontal limb of the diagonal strut member, so that the load is transmitted from the shaft hole At the same time, it can be dispersed to the vertical limb and the horizontal limb at the same time. The shaft hole plate and the diagonal strut member can be integrally combined with the force, which not only strengthens the bearing capacity of the shaft hole, but also makes the vertical limb of the end of the diagonal strut member, or horizontal. The limb is not prone to stress concentration problems.

In the present invention, the diagonal strut member is formed by 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 the vertical limb is provided with a shaft hole. The shaft hole plate is a flat plate structure, and the shaft hole plate is provided with a shaft hole. The horizontal limb of the diagonal strut member and the shaft hole plate are mutually embedded, and the shaft hole of the shaft hole plate is aligned with the shaft hole of the vertical limb of the diagonal strut member, and the surface of the shaft hole plate can be attached to the vertical limb of the diagonal strut member The surface, the axial hole plate and the horizontal limb of the diagonal strut member are perpendicularly arranged to each other, and the shaft hole plate can simultaneously make a close contact with the vertical limb and the horizontal limb of the diagonal strut member, and the shaft hole plate and the diagonal strut member The contact edge of the vertical limb and the horizontal limb is welded to complete the assembly of the hinged diagonal strut.

In the invention, the shaft hole plate is closely attached to the surface of the diagonal strut member, so that the axial hole portion of the end portion of the diagonal strut member is strengthened, but the advantage of thinning is still saved, and the space required for installation can be saved.

In the invention, the size of the shaft hole plate is smaller than the vertical limb size of the diagonal strut member, so that the welded joint between the shaft hole plate and the diagonal strut member is located at the surface, which can be easily completed by using the fillet welding method, and no multi-separator is used. As shown in the figure below, the reinforcement method is prone to problems caused by poor welding angle, or the steel plate needs to be slotted to achieve the cost of processing.

In the invention, the shaft hole plate is closely attached to the surface of the diagonal strut member, and is formed without a narrow space, so that the welding or the surface treatment is not limited to the space defect or the angle is poor, and the application or assembly is less likely to occur. The difficulties and embarrassment.

In the invention, the edge of the slot of the shaft hole plate is chamfered, and when the vertical joint of the diagonal strut member and the horizontal limb are perpendicularly joined to each other by welding, the welded bead will generate a protrusion, so the slot of the shaft hole plate The chamfering of the edge can avoid interference with the protrusion of the bead, so the shaft hole plate can be attached to the surface of the vertical limb of the diagonal strut member, avoiding the gap between the steel plates, causing poor welding joint and avoiding corrosion in the external environment. The substance is easily invaded into the gap between the steel sheets.
