Precipitation can aggravate the adverse effect to surrounding enviroment, therefore have the subway station of strict demand for surrounding enviroment, more using ground
The form of lower diaphragm wall support system.Because ground-connecting-wall is generally standard width, thus standard paragraphs bracing members can be supported directly upon even
On wall, steel can not be performed and enclose purlin, and bellend head section due to being limited by ground-connecting-wall arrangement, while in order to increase its monolithic stability
Property, control deformation, local steel can be set more encloses purlin, and the support of bracing members diagonal brace is enclosed on purlin in steel, and conventional way is in diagonal brace position
Steel enclose and drilled on purlin backboard, beat shearing resistance dowel, this mode constructional difficulties, and positioning is inaccurate, often resulting in dowel can not
Give full play to its shear behavior.
The content of the invention
The purpose of this utility model is to provide a kind of diaphram wall built-in type steel and encloses purlin plug system, by ground-connecting-wall
Upper pre-embedded steel slab, pre-embedded steel slab is enclosed purlin and is welded to connect firmly by different steel plates from steel after excavation of foundation pit, so as to reach resistance
The shearing that the transmission of bracing members diagonal brace comes.
The technical scheme that the utility model is used for：
A kind of diaphram wall built-in type steel encloses purlin plug system, it is characterised in that：
The ground-connecting-wall outside for enclosing purlin termination in steel is set encloses the vertical and vertical power transmission steel plate of purlin with steel；
Ground-connecting-wall surface on the outside of power transmission steel plate is provided with steel and encloses purlin pre-embedded steel slab, and the ground that steel encloses on the inside of purlin pre-embedded steel slab connects
It is provided with the walls and encloses the vertical shearing resistance dowel of purlin pre-embedded steel slab with steel, steel encloses purlin pre-embedded steel slab outside and to be provided with that enclose purlin with steel pre-buried
The vertical and horizontal anti-shear steel plate of steel plate, anti-shear steel plate one end is connected with power transmission steel plate.
Steel is enclosed purlin pre-embedded steel slab and is connected firmly with shearing resistance dowel by plug welding of perforating.
Shearing resistance dowel is located by connecting on ground-connecting-wall steel reinforcement cage when the steel reinforcement cage of ground-connecting-wall is performed.
Anti-shear steel plate encloses purlin pre-embedded steel slab by welding manner and steel and power transmission steel plate is connected.
The shape of the rectangular triangle of anti-shear steel plate, width outwards successively decreases from power transmission steel plate.
Power transmission steel plate is enclosed purlin and is connected using Type of Welding with steel.
The utility model has advantages below：
The utility model is fixed on ground-connecting-wall steel reinforcement cage in pre-position by shearing resistance dowel using pre-embedded steel slab,
Shaping is poured simultaneously with ground-connecting-wall, after excavation of foundation pit, steel is set up and is enclosed purlin, steel encloses purlin and passes through anti-shear steel plate and power transmission with pre-embedded steel slab
Steel plate is welded to connect, the shearing that can be transmitted to directly against diagonal brace, removes steel from and encloses answering for purlin backboard drilling implantation shearing resistance dowel
General labourer's sequence, the quantity of shearing resistance dowel, the thickness of model and anti-shear steel plate, size can be determined by bracing members diagonal brace calculation of axial force.
The shearing resistance that steel is enclosed on purlin backboard at lower edge position at diagonal brace position can be cancelled by means of which and send nail, and tool
Have the advantages that site operation is simple, quick, reliable, while destruction of a large amount of dowels to ground-connecting-wall can be reduced.
