Technical Field
The utility model belongs to the technical field of assembled concrete wallboard connects, particularly, relate to a semi-rigid connection structure of assembled wallboard.
Background
In the research of an assembled steel structure, three types of nodes are commonly used at present, namely a rigid connection node, a flexible connection node and a semi-rigid connection node.
The rigid connection node is characterized in that the external wall panel and the main structure are connected into a whole in grouting or welding modes and are deformed under stress together, and the main connection modes comprise angle steel connection, embedded sleeve connection, steel clamp consolidation, hook head bolt connection and the like. The rigid connection node is widely applied in practical engineering, has a set of complete specifications, does not need to cast concrete on site, and saves the construction period; but the rigid connection node has obvious defects, the installation operation is more complicated, and a large internal force can be generated under the action of rare earthquakes, so that the wallboard is damaged and falls off, and serious earthquake damage is caused.
The flexible node can release the stress to be applied in the prefabricated concrete structure. In the existing flexible connection node, a limit hole in the node is generally a long round hole, and a bolt can move in the long round hole, so that the external wall-hung panel and a main structure can have relative displacement, therefore, the node cannot be damaged due to the generation of larger internal force under the action of external load, and the generation of wall cracks or the falling-off condition of the wall panel can be reduced; meanwhile, the installation difficulty is low, and the construction is convenient. But the flexible connection node has the disadvantage that the strength and rigidity of the external wall panel are not fully utilized in earthquake resistance.
Although the semi-rigid connection node has good rigidity and ductility and also has certain shock resistance, the current semi-rigid connection node is still in a starting stage and lacks corresponding quantitative standards. In the research on relation between bending moment and corner of a node of a section steel bolt connection assembly type semi-rigid beam column proposed by caoyong, qianggang and the like, although it is mentioned that whether the node belongs to semi-rigidity is judged by whether the bending moment-corner skeleton curve of the node has obvious elasticity, yield and damage stages, quantitative standards are not obtained.
Chinese patent CN215519660U discloses an assembled wallboard connecting structure, which is characterized in that a reserved member is pre-embedded in a wall body, a threaded sleeve is fixedly installed in the wall body, a connecting plate is installed on one side of the wall body through a fixing member, and a connecting member is installed between the wall body and the connecting plate.

The height of the T-shaped steel 12 in the flexible joint 2 needs to be correspondingly increased due to the fact that the gap between the lower end of the wallboard 15 and the bottom of the concrete frame 14 is too large, so that steel consumption is increased, and the stability of the flexible joint 2 is not facilitated; if the gap between the lower end of the wall plate 15 and the bottom of the concrete frame 14 is too small, the mixture 3 is difficult to pour, and the construction difficulty is increased.
In some embodiments, the gap between the concrete columns and beams in the wall panel 15 and the concrete frame 14 can be filled with the mixture 3, and if cement mortar is present on site, the gap can also be filled with the cement mortar. For buildings with low fire protection requirements, polyurethane foam filling can be adopted, and the seams are sealed by silicone adhesive or other elastic sealing materials.

The utility model provides a semi-rigid connection structure's theory of operation lies in: cracks may first develop from the mix 3 under the action of an earthquake due to the relatively weak crack resistance of the mix 3. After the mixture 3 is cracked, the supporting effect of the mixture on the wall plate 15 is greatly lost, the wall plate 15 can generate micro rotation by taking the rigid node 1 as a fixed rotation point and taking the distance between the rigid node 1 and the flexible node 2 as a radius under the restraining and limiting effects of the rigid node 1 and the flexible node 2, and the energy generated by earthquake can be consumed in the process; meanwhile, the energy dissipation rubber layer 13 arranged at the rigid node 1 can absorb seismic energy. Under the comprehensive action of the rigid node 1 and the flexible node 2, the shock resistance is greatly improved.
In the normal use process, the flexible node 2 and the mixture 3 only have the limiting and supporting effects on the wall plate 15, the component which mainly plays a role in connecting the wall plate 15 and the concrete frame 14 is the rigid node 1, and the connection between the wall plate 15 and the concrete frame 14 is guaranteed in strength under the effects of the high-strength bolt 8, the shear-resistant stud 6 and the I-steel 5; simultaneously, through at 15 upper ends of wallboard and 15 lower extremes of wallboard outsourcing channel-section steel 4 in advance, can play biography power and the effect that improves the wholeness, and the restraint power of rigid node 1 department production to wallboard 15 distributes at wallboard 15's whole strip limit comparatively evenly through the transmission effect of channel-section steel 4, and this kind of measure can effectively prevent rigid node 1 and flexible node 2's local damage.
