According to the stirrup disclosed by the utility model, the consumption of steel can be saved; the construction workload of workers is reduced; and the durability and the bearing capacity of the stirrup are also enhanced.
Description
Technical field
The utility model belongs to construction engineering technical field, is specially the cross edge member monolithic welding of a kind of shear wall stirrup.
Background technology
Shear wall is claimed wind resistance wall or seismic structural wall, earthquake resistant wall again, is the body of wall that mainly bears the horizontal load that wind load or geological process cause in house or the structure, can play the effect that preventing that structure is destroyed by horizontal loading.In the construction of shear wall,, need the multiple edge member of configuration, like L type edge member, T type edge member or cross edge member etc. according to the architectural feature of building.When building edge member, normally be employed on the stirrup that connects moulding and build concrete formation at present, wherein the bonding strength of stirrup plays crucial effects to the rigidity and the intensity of edge member.As shown in Figure 1; Stirrup structure chart for existing cross edge member; It is to be made up of the outer stirrup of cross framework and the lacing wire that is arranged in this outer reinforcement, and said outer stirrup generally is made up of the rectangle hoop of two band crotches, and said lacing wire is generally S type structure; Be respectively equipped with crotch at the lacing wire two ends, lacing wire is articulated on the vertical muscle of shear wall indulging the effect that muscle and concrete play constraint through the crotch at its two ends.But this stirrup and lacing wire are when making, and crotch and stirrup repeated segments need consume the lot of reinforcing steel bar material, and this causes cost of production higher; And the lacing wire of S type is also comparatively complicated when fitting operation, causes the construction working amount of reinforcing bar bigger, and this also has considerable influence to construction period and cost of labor.
The utility model content
To above-mentioned deficiency of the prior art, the main purpose of the utility model is to provide a kind of can save the cross edge member monolithic welding of the shear wall stirrup of steel, minimizing construction working amount under the prerequisite that guarantees the stirrup structural strength.
The technical scheme of the utility model is following: the cross edge member monolithic welding of shear wall stirrup; Comprise the outer reinforcement of cross frame construction, it is characterized in that said outer reinforcement is by laterally constituting with vertical two groups of rectangular frames that are provided with; Described two groups of rectangular frames are respectively naturally by after the all-in-one-piece reinforcement bar bending process; Be connected to form with the two ends butt joint of reinforcement bar and through flash butt welding, being welded to connect a little of its two ends is the flash of light solder joint; In outer reinforcement, be provided with some stirrup limb bars laterally and/or longitudinally, the two ends of stirrup limb bar all adopt the butt welding of T type to be connected on two opposite side of outer reinforcement.
Further, said stirrup limb bar parallels with the limit of outer reinforcement or is vertical.
Further, laterally the flash of light solder joint on the rectangular frame is positioned at the mid point of its horizontal edge, and the flash of light solder joint on the vertical rectangular frame is positioned at the mid point of its vertical edge.
With respect to prior art, the utlity model has following beneficial effect:
1, steel have been saved: in the stirrup structure, saved the crotch of traditional stirrup and the length of repeated segments, the highest 25% the steel consumption amount of can saving.
2, reduced the workload of workman's construction: adopt the mode of welding to help simplifying working process, accelerating construction progress, and obvious reduction is arranged with respect to traditional installation procedure workload.
3, structure is firm, and the durability and the supporting capacity of stirrup also had raising.
Description of drawings
Fig. 1 is the stirrup structural representation of existing cross edge member;
Fig. 2 is the structural representation of the cross edge member monolithic welding of the utility model shear wall stirrup.
Among the figure, 1-outer reinforcement, 2-stirrup limb bar, 3-flash of light solder joint.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
As shown in Figure 2; The cross edge member monolithic of the shear wall of the utility model is welded stirrup, comprises the outer reinforcement 1 of cross frame construction, and said outer reinforcement 1 is by laterally constituting with vertical two groups of rectangular frames that are provided with; Described two groups of rectangular frames are respectively naturally by after the all-in-one-piece reinforcement bar bending process; Be connected to form with the two ends butt joint of reinforcement bar and through flash butt welding, being welded to connect a little of its two ends is flash of light solder joint 3.Wherein, Laterally the flash of light solder joint 3 on the rectangular frame is positioned at the mid point of its horizontal edge; Flash of light solder joint 3 on the vertical rectangular frame is positioned at the mid point of its vertical edge; Help the frame stressing balance like this, laterally the horizontal axis square crossing of the vertical axis of rectangular frame and vertical rectangular frame forms cross.In outer reinforcement 1, be provided with some stirrup limb bars 2 laterally and/or longitudinally; Wherein, Laterally be provided with at least two vertical stirrup limb bars in the rectangular frame; In vertical rectangular frame, be provided with at least two horizontal stirrup limb bars, said stirrup limb bar 2 parallels with the limit of outer reinforcement 1 or is vertical and be symmetrical set with respect to the axis of corresponding rectangular frame separately.The two ends of stirrup limb bar 2 all adopt the butt welding of T type to be connected on two opposite side of outer reinforcement 1, form support and reinforcing to outer reinforcement 1 with this, to increase the globality of stirrup structure.
Stirrup limb bar 2 in the utility model is rectilinear form; Its termination can directly be welded fixing; Utilization rate to material is higher; Therefore the material of 160mm ~ 280mm length at least can be saved with respect to every traditional of S type stirrup limb bar, and, when producing in batches, cost can be effectively reduced because its consumption is very big.Butt welding of T type and the flash butt welding adopted in the utility model are prior art; Wherein the butt welding of T type is that end face with two workpiece compresses all the time; Utilize resistance heat to be heated to plastic state, apply the method that upsetting force when only keeping welding (or do not add upsetting force pressure) is accomplished welding then rapidly; And flash butt welding is to be assembled into banjo fixing butt jointing through the resistance weldment; Energized is also moved its end face closely to reach local contact gradually; Utilize these contact points of resistance heat heating (producing flash of light); Make the end plane metal fusing, when the end reaches predetermined temperature in the certain depth scope, apply the method that upset force is accomplished welding rapidly.Can keep the bonding strength of stirrup limb bar through the mode of butt welding of T type and flash butt welding, also simplify operation, the workload when having reduced construction.
