Compared with prior art, the utility model has the beneficial effects that:
(1) easy construction.
Interconnecting piece upper and lower sides SRC column Shaped Steels section local wide, passes through shaped steel sleeve connection in the utility model.Sleeve
It is prefabricated on the downside of interconnecting piece on SRC columns Shaped Steel by high-strength bolt, it only need to will connection upside SRC column Shaped Steels when site operation
It is fixed in insert type steel bushing and with high-strength unilateral bolt and intercolumniation connection can be completed.Common weldering is connected compared to current shaped steel
It connects and is bolted entirely, shaped steel sleeve connection is few using bolt quantity, and avoids the welding sequence of construction site;Compared to complete
Cast-in-place SRC intercolumniations connect to be connect with the prefabricated SRC intercolumniations using equivalent cast-in-place thought, and the utility model is connected using dry type, is applied
Work scene is not necessarily to large area concrete operation, and interconnecting piece is not provided with stirrup, is held by rationally designing shaped steel sleeve reinforcement interconnecting piece
Carry power, easy construction.In the present invention, the both sides that muscle is anchored at column in precasting yard by anchorage are indulged in column, scene is applied
Working hour is not necessarily to bar connecting process, further simplifies construction.
(2) construction quality is high.
Multi-purpose compared to the connection of current shaped steel is bolted and welds entirely, and the shaped steel sleeve that the utility model uses accounts for
There is the advantage that construction quality is high.
Because in SRC columns use cross-shaped steel, and SRC column Shaped Steels cross-sectional sizes can according to actual loading situation and
It is fixed.Therefore in complete be bolted, in the case where shaped steel section is smaller, being bolted can be difficult to ensure because construction space is smaller
Quality of connection;In being welded to connect, because site operation personnel specialty quality is very different at this stage, and welding is needed using a variety of
Necessary instrument facility, leads to that construction quality is difficult to ensure and process is increasingly complex.
The use of the utility model interconnecting piece shaped steel shaped steel sleeve, avoids the welding procedure of construction site, and shaped steel set
Cylinder is prefabricated in the factory and passes through preassembling, at the construction field (site) only need to be from outside while construction precision can obtain being effectively ensured
It tightens high-strength one-way bolt and shaped steel connection can be completed, do not influenced by construction space, and can guarantee higher construction quality.
(3) functional promotion.
Common iron or low-yield steel can be used in shaped steel sleeve in the utility model.Using common iron
When, pass through rational design, it is ensured that the bearing capacity and ductility demand of interconnecting piece;When using low-yield steel, interconnecting piece can
As energy consumption member, when reasonable Arrangement, is conducive to Aseismic Design.In the higher area of shockproof requirements, dissipative cell can be added in intercolumniation
Further promote shock resistance.
