The construction method of the L-shaped flexible joint coupled wall with pre-buried seam beam section, including the first wall unit and The prefabricated process and assembled in situ process of second wall unit, are as follows:
The prefabricated process of first wall unit:
Step 1 makes the pre-buried beam of the first wall unit, the pre-buried seam column of the first wall unit and is correspondingly connected with the first wall unit Shear stud and the first wall unit auxiliary bar.
Step 2, pre-buried seam beam section in making, in pre-buried seam beam section.
Step 3, by the pre-buried beam of the first wall unit, the pre-buried seam column of the first wall unit, upper pre-buried seam beam section and in it is pre-buried Seam beam section correspondence is fixed on design position.
Step 4 carries out the first wall unit framework of steel reinforcement of binding according to design requirement;
Step 5 connects the first wall unit seam column in the pre-buried seam column surrounding of the first wall unit and constructs muscle.
Step 6 installs the template of the first wall unit, and the one side in four faces up and down or multi-panel progress water Flat key slot or coarse surface treatment.
Step 7 pours the concrete of the first wall unit.
Step 8 is demoulded after pouring molding and maintenance, completes the prefabricated process of the first wall unit.
The prefabricated process of second wall unit:
Step 1 makes the pre-buried beam of the second wall unit, the pre-buried seam column of the second wall unit and is correspondingly connected with the second wall unit Shear stud and the second wall unit auxiliary bar.
Step 2 makes pre-buried vertical abutment joint shell of column.
Step 3 corresponds to the pre-buried beam of the second wall unit, the pre-buried seam column of the second wall unit and pre-buried vertical abutment joint shell of column It is connected on design position.
Step 4 binds the second wall unit framework of steel reinforcement.
Step 5 connects the second wall unit seam column in the pre-buried seam column surrounding of the second wall unit and constructs muscle.
Step 6 installs the template of the second wall unit, and the one side in four faces up and down or multi-panel progress water Flat key slot or coarse surface treatment.
Step 7 pours the concrete of the second wall unit.
Step 8 is demoulded after pouring molding and maintenance, completes the prefabricated process of the second wall unit.
Assembled in situ process:
Prefabricated the first wall unit and the second wall unit are transported to construction site, start on-site construction processes by step 1.
Step 2, by the upper pre-buried seam of the upper pre-buried seam short beam and upper pre-buried seam beam section of pre-buried vertical abutment joint shell of column Beam is correspondingly connected with, and pre-buried seam short beam pre-buried seam beam section in is correspondingly connected in pre-buried vertical abutment joint shell of column.
Step 3 fills filler in seaming position, and the assembled in situ for completing the L-shaped flexible joint coupled wall of single layer is applied Work.
The assembled in situ process of multilayer the first wall unit and/or the second wall unit:
Step 1 docks the lifting of upper layer the first wall unit with lower layer the first wall unit, by two layers of the first wall list The pre-buried seam column of member corresponds to spot welding connection.
Step 2 sloughs suspension hook, passes through high-strength spiral shell to the corresponding pre-buried seam column of first wall unit of two layers of first wall units Bolt or bolted and welded connection.
Step 3 is arranged framework of steel reinforcement in the seam areas up and down of the double-deck first wall unit, and installs seam areas up and down Concrete-pouring template.
Step 4 pours the concrete of upper and lower seam areas.
Step 5 is conserved, and the assembled in situ construction of the double-deck first wall unit, the construction of the double-deck second wall unit are completed It is similar with the first wall unit:The pre-buried vertical abutment joint column of the double-deck second wall unit and the pre-buried seam column of the second wall unit are corresponded to and connected It connects and is cast in concrete and complete docking.
Step 6 repeats step 1 to step 5, completes the assembled in situ construction of the L-shaped flexible joint coupled wall of multilayer.
Compared with prior art the invention has the characteristics that and advantageous effect:
The present invention is based on finite element theories, establish finite element model and connect limb to the L-shaped flexible joint with seam girder steel section Wall system carries out mechanical analysis, verifies the reliability of its node, and pre-buried seam beam section is embedded in wall unit and coordinates pre-buried erect Pre-buried seam short beam into seam shell of column butts up against formation L-shaped flexible joint coupled wall in filler, has stress relationship bright Really, the advantages that connection relation is reliable, convenient for construction.
First, connection relation is reliable:L-shaped flexible joint coupled wall is by the pre-buried seam beam being embedded in the first wall unit It is connected with the assembled in situ of filler being implemented in combination with the pre-buried vertical abutment joint shell of column being connected in the second wall unit, girder steel With the combination of filler so that the first wall unit and the second wall unit are mutually assisted in lateral deformation, are reached each wall limb and are stablized Purpose.
Secondly, stress relationship is clear:Flexible connection between first wall unit and the second wall unit so that in structural system Vertical, horizontal shear wall bears the division of labor of horizontal force action definitely, realizes that fining analysis provides for structural analysis and design It ensures.
Again, it is convenient for construction:The connection that pre-buried seam beam section and pre-buried vertical abutment joint shell of column are used at vertical abutment joint, only needs By between wall assembly unit pre-buried seam beam section and pre-buried vertical abutment joint shell of column carry out high-strength bolt or bolted and welded connection, so Flexible material joint filling is used afterwards, it is real instead of the mode for requiring edge member concrete cast in situs in fabricated construction Show involvement to connect so that fabricated construction site operation greatly simplifies, the wet connection with existing fabricated shear wall vertical abutment joint It compares, there is apparent advantage.
Then, optimize structural seismic performance:Pre-buried seam beam section is corresponding with pre-buried vertical abutment joint shell of column to pass through high-strength bolt Or bolted and welded connection so that two wall assembly units are provided for the stability of wall having carried out out-of-plane support each other It ensures, which not only weakens the transmission of moment of flexure between two walls so that structural system vertical, horizontal wall stress is brighter Really, and the pre-buried seam beam section energy dissipation capacity between prefabrication and assembly construction unit is played more abundant, to optimize structure The anti-seismic performance of system.
Finally, it is easily repaired after macroseism:In view of being flexible connection between the first wall unit and the second wall unit, in severe earthquake action Under, large deformation at flexible connection can be caused, to most of seismic energy at the node that dissipated, to reduce wall limb vertical The cracking of seam crossing only needs to change pre-buried seam girder steel section exposed parts and repairs a small amount of wall limb crack after shake.
To sum up, node of the present invention connection is safe and reliable, has good anti-seismic performance, at the same realize again prefabrication and In-site installation, which synchronizes, to carry out:Be prefabricated in the factory wall assembly unit, at the scene splicing installation so that structural elements makes and installation It is carried out at the same time, improves the speed of application of agent structure, guarantee is provided for the completion on schedule of project under construction, in work progress, The assembly of structure is combined, and the wet construction amount of coagulation soil scene is reduced, to reduce the usage amount of template, temporary support, into And reduce the generation of building waste, reach the requirement of section material and environmental protection, realizes the purpose of green construction.
