Prefabricated parapet bears down on one reserving hole, is connected by dowel pre-buried in wall body with prefabricated parapet.Employed in the method many
Connection method is planted, and wet trade operation is more.The connection of wall body top and bottom is required to accurately connect positioning, and two pieces of walls
The wider width of section is poured after between body, installation process is needed to use compared with instruments such as multi-templates so that work progress is complex, limit
Its popularization and application is at different conditions made.
The content of the invention
It is an object of the invention to provide a kind of precast concrete daughter wall member.Simple structure of the present invention, it is convenient and practical.
Another object of the present invention is to provide a kind of attachment structure of precast concrete daughter wall member.The present invention is being protected
Card parapet be connected with agent structure it is safe and reliable on the premise of, with in-site installation with dry type connect based on, wet trade amount it is few,
Connection adjustable, the flexible advantage of positioning, therefore the construction of prefabricated concrete structure parapet can be simplified, and it is easy to spread should
With.
The technical scheme is that：Precast concrete daughter wall member of the invention, including parapet wall body, bracket and
Parapet bears down on one, and parapet is beared down on one and is connected by parapet wall body between bracket.
The attachment structure of precast concrete daughter wall member of the invention, precast concrete daughter's wall member two ends be provided with
The precast concrete construction post of agent structure component connection, precast concrete construction post is used as precast concrete daughter's wall member
Level connection joint bearing, the company with agent structure component is realized by connector in precast concrete parapet member bottom section and two ends
Connect.
Precast concrete parapet member lower is connected with agent structure component using joint bar grouting in the present invention, and prefabricated
Concrete daughter's wall member or so two ends are connected by screw bolts with prefabricated constructional column, are realized by above two connected mode prefabricated
The firm connection of concrete daughter wall member and agent structure component.Prefabricated constructional column is pre-buried vertical with agent structure component
Being reliably connected for connection reinforcing bar ensures that prefabricated constructional column can be realized as the level connection joint bearing of precast concrete daughter's wall member
The horizontal loading that precast concrete daughter's wall member is undertaken effectively is passed into agent structure component.Attachment structure of the invention
It is easy to the installation of prefabricated daughter's wall member, the bracket of its bottom can be placed directly when installing precast concrete daughter's wall member
In on concrete cast-in-situ layer, it is to avoid precast concrete daughter wall member installs positioning needs temporary support, and agent structure structure
Pre-buried connection dowel carries out that device to hole is easy for installation with preformed hole in bracket in part, in the absence of the problem of pre-buried dowel location difficulty.
The invention provides a kind of easy construction, simple structure, reasonable stress, convenient and practical new precast concrete parapet and dress
With formula reinforced concrete structure main body connected mode.
