The node of the steel structure beam column also meets the requirement of ductility design.
Under the action of an earthquake, the steel damage energy-consumption connecting component with the low yield point enters a yield state before a main body structure made of common steel is adopted, the plastic deformation of the structure is concentrated, most of earthquake energy is effectively dissipated, the main body structure keeps elasticity, and the fuse wire function is achieved. Adopt high strength bolted connection, shake the back through changing the too big damage power consumption coupling assembling that warp, realize the target of quick recovery structure service function. The node connected by the high-strength bolt is convenient and quick to process, manufacture, disassemble and install, the damaged element is manufactured by the connecting component of the node, the damaged element does not need to be additionally increased, higher anti-seismic performance is realized at lower cost, and the popularization and the application in future engineering are facilitated.
The existing beam-column nodes are generally fixedly connected in a nested clamping mode, once the connecting mode is damaged, the deformation can cause that a component is difficult to separate and needs to be cut and reinforced, so that high earthquake resistance and repairability are preferentially realized for the excellent earthquake resistance, and how to realize high-efficiency repairability is a difficult problem for controlling damaged parts at the nodes.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose, the utility model discloses to the above-mentioned problem that has the node position easily destroyed and the pertinence provide a damage controllable assembled steel construction beam column node, it has realized that the damage point is controllable, the subassembly is easily dismantled and is changed, the characteristics of high bending resistance.
The utility model discloses the problem that will solve is realized by following technical scheme:
the utility model provides a controllable assembled steel construction beam column node damages which characterized in that: the T-shaped structure comprises a vertical column and a cross beam which form a T-shaped structure, wherein the vertical column and the cross beam are connected through an L-shaped connecting piece arranged at a first corner at the outer side;
triangular ribs are arranged between each L-shaped connecting piece, and notches for resisting folding are arranged in the middle of each rib or on the inner edge of each rib.
Furthermore, the upright posts and the cross beams are all made of I-shaped steel.
Furthermore, bending brackets are respectively arranged on two sides of the web plate of the upright post, the bending brackets on the two sides are symmetrical, and one flange of the bending bracket self-supporting post is connected to the other flange.
Furthermore, the bending support comprises a flat plate fixed on the web plate and inclined plates obliquely extending along two ends of the flat plate and connected to the flanges.
Furthermore, the straight line formed by the straight extension of the outer edge of the rib is a bending-resistant line, and the bending-resistant lines corresponding to the extension direction of the inclined plate are parallel.
Furthermore, each L-shaped reinforcing member is provided with a round notch on both sides for bending resistance.
The utility model discloses for the beneficial effect that has now:
the L-shaped steel plate is connected with the bolt, so that the stress is reasonable and clear, welding is not needed, welding seams are avoided on connecting members, the installation and operation are simple, and the ductile deformation capacity is good.
The high-strength bolt and the steel plate are used as main deformation energy-consuming components, so that the high-strength bolt and the steel plate have high energy-consuming capacity, simple economic structure, convenience in replacement, quickness in repair and low cost.
The structure is controllable in failure mode under the action of major earthquake, deformation and energy consumption of the structure can be concentrated on the steel plate under the action of rare earthquake, only the steel plate enters plastic energy consumption, the rest part and the structure main body are in the elastic range to achieve the control of damage, the main structure is protected from being damaged under the action of earthquake, and the main structure can be quickly repaired after being damaged.
The problems of poor node mechanical property and poor anti-seismic property of the existing steel structure connection welding node are solved, and the defects of the prior art are overcome. The semi-rigid connection of beam column node, the assembly of building structure accords with the design requirement of "strong post weak beam". The invention makes up the defects of the prior steel structure beam column node from three angles of replacement, bolt energy consumption and damage control.
