Technical field
The present invention relates to technical field of buildings, especially relates to a kind of L-type assembled stem steel plate shear force wall and its dress
With construction method.
Background technology
Building industrialization is a kind of low-carbon, green, environmental protection, efficient mode of construction, is the Prefabrication in factory, transport
The drawbacks of carrying out assembling assembly to scene, overcome traditional construction pattern, effectively improves architecture production efficiency, improves structure safety
Performance, energy-saving and emission-reduction, improve resource utilization, reduce construction cost.
At present, for assembled architecture, two mainly influence the problem of structure is safe：1st, component anti-seismic performance；2nd, structure
Bonding strength between part.In traditional reinforced concrete shear wall in order to improve its anti-seismic performance, it is necessary to configure a large amount of reinforcing bars come
Resistance seismic shear, when factory makes and processes, bar-mat reinforcement and steel reinforcement cage etc. are not implemented completely certainly fabricated shear wall at present
Dynamic metaplasia production, most still by manually binding, production efficiency is low, and quality is difficult to ensure that, labour cost is higher, and is difficult to full
Foot automation pours the demand of production line.Currently, the connection between traditional assembled steel reinforced concrete shear wall member is mostly
Connected using grout sleeve, the form such as slurry anchor connection, above type of attachment, component requirement on machining accuracy is high, constructional difficulties, efficiency
Lowly, simultaneously as the bad control of internal grouting quality, can seriously affect bonding strength between component, reduce integrally-built peace
Full performance.
The content of the invention
To solve the above problems, the present invention provides a kind of L-type assembled stem steel plate shear force wall and its assembling construction party
Method, program overall performance is good, it is simple to make, without cumbersome steel bar meter process, and scene splicing is convenient and reliable, can be completely achieved mark
Standardization design, be factory produced, prefabricated construction, greatly improves production and processing and construction efficiency；Meanwhile connect between program component
Intensity height is connect, structural safety performance is reliable, and anti-seismic performance is good.
To achieve the above object, the present invention adopts the following technical scheme that：
