Compared with the prior art, the utility model has the following characteristics and beneficial effects:

Based on the finite element theory, the utility model establishes a finite element model to perform mechanical analysis on the L-shaped flexible jointed limb wall system with jointed steel beam sections, verifies the reliability of its nodes, and pre-embeds the pre-embedded jointed beam sections. In the wall unit, the pre-embedded joint short beam in the pre-embedded vertical joint column section is docked in the filler to form an L-shaped flexible joint joint limb wall, which has the advantages of clear force relationship, reliable connection relationship, and convenient construction. .

First, the connection relationship is reliable: the L-shaped flexible jointed limb wall relies on the pre-embedded joint beams embedded in the first wall unit and the pre-embedded vertical joint column sections and fillers connected in the second wall unit The on-site assembly connection realized by the combination of the steel beam and the filler makes the first wall unit and the second wall unit support each other in the lateral deformation, so as to achieve the purpose of stabilizing each wall pier.

Guaranteed.

Again, it is convenient for construction: the vertical joints are connected by the pre-embedded joint beam section and the pre-embedded vertical joint column section, and only the pre-embedded joint beam section and the pre-embedded vertical joint between the wall assembly units are connected. The joint column section is connected by high-strength bolts or bolts and welds, and then filled with flexible materials, which replaces the method of on-site pouring of concrete on the edge components in the prefabricated structure, and realizes dry connection, which greatly simplifies the on-site construction of the prefabricated structure. Compared with the wet connection of the vertical joints of the existing prefabricated shear walls, it has obvious advantages.

Then, optimize the anti-seismic performance of the structure: the pre-embedded joint beam section and the pre-embedded vertical joint column section are connected by high-strength bolts or bolted welding, so that the two wall assembly units support each other out of plane, which is the foundation of the wall. This connection method not only weakens the moment transfer between the two walls, but also makes the longitudinal and transverse walls of the structural system more clearly stressed, and makes the pre-embedded joint beams between prefabricated assembly units consume energy The capacity can be fully utilized, thereby optimizing the seismic performance of the structural system.

Finally, it is easy to repair after a strong earthquake: in view of the flexible connection between the first wall unit and the second wall unit, under the action of a strong earthquake, it will cause a large deformation of the flexible connection, thus dissipating most of the seismic energy at the joint, thus The cracking of the wall piers at the vertical joints is reduced. After the earthquake, it is only necessary to replace the exposed parts of the steel beam sections with embedded joints and repair a small amount of cracks in the wall piers.

To sum up, the node connection of the utility model is safe and reliable, has good anti-seismic performance, and at the same time realizes factory prefabrication and on-site installation at the same time: the wall assembly unit is prefabricated in the factory, spliced and installed on site, so that the structural components are manufactured and installed at the same time , which improves the construction speed of the main structure and provides a guarantee for the completion of the construction project on schedule. During the construction process, the assembly and combination of the structure reduces the amount of wet work on the concrete site, thereby reducing the use of formwork and temporary supports, thereby reducing It reduces the generation of construction waste, meets the requirements of material saving and environmental protection, and realizes the purpose of green construction.

Step 2: Take off the hook, and connect the pre-embedded joint column of the first wall unit corresponding to the first wall unit of the two floors through high-strength bolts or bolt welding.

Step 3, setting up the reinforcement skeleton at the upper and lower joints of the double-layer first wall unit, and supporting the concrete pouring formwork at the upper and lower joints.

Step 4, pouring concrete at the upper and lower joints.

Step five, carry out maintenance and complete the on-site assembly construction of the double-layer first wall unit. The construction of the double-layer second wall unit is similar to the first wall unit: the pre-embedded vertical joint column of the double-layer second wall unit The pre-embedded joint columns of the second wall unit are correspondingly connected and poured in concrete to complete the butt joint.

Step 6: Repeat steps 1 to 5 to complete the on-site assembly construction of the multi-layer L-shaped flexible joint wall.

While constructing the double-layer L-shaped flexible joint limb wall, the floor slab 4 is constructed.
