Wherein, as shown in Figure 2, described well formula Vierendeel girder 30 is positioned at the connected node position that concrete column 10 and arch without beam 20 intersect, and it is concealed in arch without beam 20 planes.As shown in Figure 3, this well formula Vierendeel girder 30 comprises two horizontal peg stiffeners 31 and two vertical peg stiffeners 32, this horizontal peg stiffener 31 be connected mutual vertical connection of peg stiffener 32, and as shown in Figure 4, each horizontal peg stiffener 31 and vertical peg stiffener 32 include rectangle crossbeam 33 and several pegs 34, these peg 34 equal vertical weldings are in the upper surface of rectangle crossbeam 33, and all pass between arch without beam 20 and the concrete column 10 at each peg 34 of connected node position.
In the present embodiment, in conjunction with Fig. 3 and Fig. 4, the rectangle crossbeam 33 of the horizontal peg stiffener 31 of each bar and vertical peg stiffener 32 all is to be welded by two sections rectangular steel plates (see figure 5)s.See Fig. 4, the rectangle crossbeam 33 of described horizontal peg stiffener 31 is to be made of length different the first rectangular steel plates 311 and the second rectangular steel plates 312, the rectangle crossbeam 33 of described vertical peg stiffener 32 is to be made of length different the 3rd rectangular steel plates 321 and the 4th rectangular steel plates 322, this first rectangular steel plates 311, the second rectangular steel plates 312 and the 3rd rectangular steel plates 321, the head end of the 4th rectangular steel plates 322 pools together welding and forms groined type structure (seeing Fig. 3), and in four the first weld seam 35 and the second weld seams 36 that corners formation is intervally arranged of groined type structure, this first weld seam 35 is mutually vertical with the second weld seam 36.Particularly, the head end of described the second rectangular steel plates 312 and the 4th rectangular steel plates 322 extends welding section 313 and switching phase 314, and the switching phase 314 of each second rectangular steel plates 312 and the 4th rectangular steel plates 322 encloses the four edges (see figure 3) that forms the groined type structure centre.
As shown in Figure 4, described peg 34 is that a bond pads is at vertically peg stiffener 32 and the laterally upper surface of peg stiffener 31 in twos, and respectively organize and keep at regular intervals between the peg 34, particularly, as shown in Figure 6, each peg 34 includes peg bar 341 and peg cap 342, welds in the bottom of this peg bar 341.
As shown in Figure 2, described arch without beam 20 is Concrete Slab 20, arrangement of reinforcement 40 in this arch without beam 20 has at least two-layer, its every layer arrangement of reinforcement 40 is all horizontal, vertical being laid in the same plane, and, the horizontal stroke of each arrangement of reinforcement 40, be longitudinally set with the horizontal peg stiffener 31 of putting direction and well formula Vierendeel girder 30, the horizontal stroke of vertical peg stiffener 32, be longitudinally set with that to put direction identical, its at the middle and upper levels arrangement of reinforcement 40 be laid on the surface of well formula Vierendeel girder 30, this lower floor's arrangement of reinforcement 40 is passed by the below, bottom surface of well formula Vierendeel girder 30, thereby behind the arch without beam 20 integrated poured concrete, this well formula Vierendeel girder 30 is embedded in the arch without beam 20, can not expose the superstructure surface.
As shown in Figure 2, described concrete column 10 is reinforcing bar or profile steel concrete column 10, is supporting arch without beam 20, and it can be cylinder or square or rectangular column structure, joins shaped steel in it and can be passed by the middle hole of well formula Vierendeel girder.In addition, these concrete column 10 interior some reinforcing ribs 11 that vertically are provided with, this reinforcing rib 11 can be round steel or angle steel.The horizontal peg stiffener 31 of well formula Vierendeel girder 30, vertically the arrangement of reinforcement 40 of peg stiffener 32, arch without beam 20 in the top of this concrete column 10 all can with reinforcing rib 11 anchorings.
Work progress of the present invention is as follows:
At first, welding well formula Vierendeel girder 30, make two sections vertical peg stiffeners 32 be vertically welded in respectively the both sides of the central point of horizontal peg stiffener 31, and calculate to guarantee bonding strength by the welding of equal strength design, so that the Vierendeel girder of superstructure forms the groined type structure.
Then in the upper surface weld stud 34 of well word rectangle crossbeam forming well formula Vierendeel girder 30, and this well formula Vierendeel girder 30 is lifted on the top of concrete column 10 formworks.
Then, lay netted arrangement of reinforcement 40 in the above and below of cross steel frame, these arrangement of reinforcement 40 horizontal strokes, be longitudinally set with that to put direction identical with horizontal stroke, the longitudinal direction of laterally peg stiffener 31, vertical peg stiffener 32.
At last, seal the template of concrete column 10 and arch without beam 20, can form whole arch without beam 20 by concreting, certainly, the concreting in the concrete column 10 should be poured into a mould prior to superstructure, otherwise should keep support, avoids well formula Vierendeel girder 30 stressed.
By experimental results demonstrate, above-mentioned well formula Vierendeel girder 30 is placed between concrete column 10 and the arch without beam 20, can greatly strengthen shock resistance and the punch resistant capability of building structure.
In sum, design focal point of the present invention is, it mainly is to adopt well formula Vierendeel girder 30 to strengthen in the node area that concrete column 10 and arch without beam 20 intersect, but its punch resistant capability of Effective Raise, need not to arrange in addition cap, have the floor structure of raising and the bending rigidity of support column junction and the effect of anti-seismic performance, also can make things convenient for simultaneously the node processing of concrete column 10 and floor structure and reduce difficulty of construction.
In addition, the horizontal peg stiffener 31 of well formula Vierendeel girder 30 and vertical peg stiffener 32 are by being welded, and peg 34 is vertically set on the upper surface of rectangle crossbeam 33, effectively strengthens the anchoring effect of well formula Vierendeel girder 30 between arch without beam 20 and concrete column 10.
The above, it only is preferred embodiment of the present invention, be not that technical scope of the present invention is imposed any restrictions, therefore every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any trickle modification, equivalent variations and modification that above embodiment does.
