Abstract
The invention relates to a steel plate-brickwork combination stressed building component and a production method thereof, belonging to the technical field of structural engineering. The production method comprises the following steps: after mounting a wall surface wrapping steel plate of which the plate surface is provided with through holes on the wall surface of the existing wall, dismantling partial walls adjacent to the wall surface wrapping steel plate so as to respectively form brickworks of an underpinned beam and a supporting column; then mounting section wrapping steel plates on the sections of the brickworks and welding and sealing the section wrapping steel plates and the wall surface wrapping steel plate so as to form a wrapping steel plate shell; and finally, filling structural adhesive between the brickworks and the wrapping steel plate shell under pressure. The invention adopts the existing wall as the brickworks and reinforces the wall by arranging the steel plates on both sides of the existing wall so as to avoid carrying out wet operation in a construction process and effectively shorten the construction period. Moreover, a large quantity of templates and scaffoldsupports needed by concrete pouring in the prior art are reduced so as to save the construction cost, and meanwhile, the condition that the section of the component is larger to influence the attraction and the use of buildings is avoided.
Description
Technical field
The present invention relates to a kind of steel plate-brickwork combination stressed building component and production method thereof, be applied to existing masonry load-carrying members house when carrying out large-space rebuilding, that sets up in the time of need removing load bearing wall underpins beam, post, belongs to technical field of structural engineering.
Background technology
In order to satisfy the large space demand of existing masonry load-carrying members house on function of use, need partial weight-bearing masonry (most for brick) wall extracted to carry out spatial spread, cause the transfer route of original body of wall bearing load to change, must be provided with and effectively underpin beam, post primary structure member, just can guarantee the safety and normal use of structure.
At present, carry out the engineering of large-space rebuilding about the masonry load-carrying members, adopt traditionally comparative maturity underpin beam, the post primary structure member is the combining structure of reinforced concrete structure, steel and concrete etc.In general, prior art is fairly perfect and safe and reliable on construction technology, but, work owing to have the concrete construction part and can not take into full account original body of wall, there is following weak point in it: there is the concrete construction part in (1), concrete normal curing time need be guaranteed, increased the early strong concrete that waits Admixture even adopt, just can carry out form removal after also needing a period of time, normally come into operation, therefore, this employing concrete wet trade forms underpins beam, the bearing post primary structure member, curing time is longer, has prolonged the construction period; (2) beam that increases newly, the column section part overwhelming majority are the outer outsides that wraps in residual allowable ratio of height to sectional thickness of masonry wall or column, be after it satisfies certain technical requirements, be embedded in body of wall inside, the beam that increases newly in the prior art, post are not considered residual masonry subparticipation work, simultaneously in order to satisfy the Concrete Construction quality, the sectional dimension that increases beam, post newly can not be too small, directly influences the attractive in appearance and use of building; (3) concretely build shaping and need a large amount of templates and scaffold to support, increase construction cost, easily cause simultaneously the job site crowded, security incident takes place, greatly jeopardize constructor's safety.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of steel plate-brickwork combination stressed building component is provided.It adopts existing wall segment as inner core, and in the outside of this existing wall segment steel plate is installed and is reinforced, thereby avoids constructing of steel plate-brickwork combination stressed member to carry out wet trade in the process, shortens the construction period effectively; Simultaneously, also reduce needed a large amount of templates of concreting and scaffold bracing frame in the prior art, save construction cost; It is attractive in appearance and use to avoid occurring the member section building that influences bigger than normal in addition.
In order to realize above technical purpose, the present invention adopts following technical scheme:
A kind of steel plate-brickwork combination stressed building component comprises encased steel plate housing and masonry.Described masonry is made with the existing body of wall that formation underpins beam, bearing post with pending large-space rebuilding, described encased steel plate housing is arranged at the periphery of masonry, and offer the through hole that is used for reperfusion structure glue on the encased steel plate housing, and link into an integrated entity by securing member and through hole reperfusion structure glue between encased steel plate housing and the masonry.
The encased steel plate housing comprises metope encased steel plate and section encased steel plate.The metope encased steel plate is two, this two metopes encased steel plate is relatively arranged on two metopes of the existing body of wall that is built into masonry, and two metope encased steel plates are fixedlyed connected by securing member with placing masonry therebetween, and the section encased steel plate is installed on the section of masonry, and section encased steel plate and metope encased steel plate welded closure are integral.In work progress, should carry out steel plate welding back reperfusion structure glue earlier, must not put upside down sequence of construction.
Between described metope encased steel plate and the masonry cement sand bed is set, this cement sand bed is bonded on the masonry, and is provided for the groove of reperfusion structure glue on this cement sand bed.Simultaneously, structure glue can penetrate into inner masonry by the securing member perforation along groove.
