The utility model is achieved by following technical solution.
A kind of Prefabricated beam connection structure that is conducive to antidetonation, comprise precast beam body, foundation columns and for connecting the second stage concrete of precast beam body and foundation columns, described foundation columns top is provided with groove, foundation columns outside is reserved with post reinforcing bar, precast beam body beam-ends is reserved with beam steel, and described precast beam body is arranged in groove, and beam steel and post reinforcing bar are fixed together by welding, second stage concrete is built between foundation columns and precast beam body, and post reinforcing bar and beam steel are encased completely.
The width of described groove is than the large 5cm～10cm of the width of precast beam body, and the degree of depth is identical with the height of precast beam body.
Reserved beam steel in described precast beam body is at the bottom of beam end is bent to beam downwards, and downward bent part divides by welding manner and is fixed on post reinforcing bar 21.
Described groove connects foundation columns, and foundation columns mixed lateral column steel bar preassembling is left to foundation columns top.
The beneficial effects of the utility model are:
Compared with prior art, the syndeton of precast beam described in the utility model, its bean column node welds by the vertical posts reinforcing bar of foundation columns and the lower camber beam reinforcing bar of precast beam body, and forms whole skeleton, has reduced the possibility that bean column node is thrown off, bean column node power transmission is clear and definite, coupling stiffness is large, and good stability is connected firmly, construct simple and convenient, speed of application is fast.The safety factor that has increased the permanent normal operation of framework, in the long run, has significant economic benefit, can be in precast beam link technique field wide popularization and application.

The specific embodiment
Below in conjunction with accompanying drawing, further describe the technical solution of the utility model, but described in claimed scope is not limited to.
As shown in Figures 1 to 5, a kind of Prefabricated beam connection structure that is conducive to antidetonation described in the utility model, comprise precast beam body 1, foundation columns 2 and for connecting the second stage concrete 3 of precast beam body 1 and foundation columns 2, described foundation columns 2 tops are provided with groove 22, foundation columns 2 outsides are reserved with post reinforcing bar 21, precast beam body 1 beam-ends is reserved with beam steel 11, described precast beam body 1 is arranged in groove 21, and beam steel 11 is fixed together by welding with post reinforcing bar 21, second stage concrete 3 is built between foundation columns 2 and precast beam body 1, and post reinforcing bar 21 and beam steel 11 are encased completely.Adopt the technical program, because bean column node is by beam steel 11 welding reserved with precast beam body 1 of the vertical posts reinforcing bar 21 of foundation columns 2, as shown in the weld 4 in Fig. 3, make post reinforcing bar 21 form whole skeleton in beam steel 11, and by second stage concrete 3, groove 22 is built and filled up, make post reinforcing bar 21 and beam steel 11 be placed in second stage concrete 3 completely interior fixing, thereby reduced the possibility that bean column node is thrown off, make bean column node power transmission clear and definite, coupling stiffness is large, good stability.
The width of described groove 22 is than the large 5cm～10cm of the width of precast beam body 1, and the degree of depth is identical with the height of precast beam body 1.To meet the requirement of strength of building the second stage of coagulation body soil 3, node is connected more firm.
Described groove 22 connects foundation columns 2, and foundation columns 2 mixed lateral column reinforcing bars 21 are left to foundation columns 2 tops in advance.
Reserved beam steel 11 in described precast beam body 1 is at the bottom of beam end is bent to beam downwards, and downward bent part divides by welding manner and is fixed on post reinforcing bar 21.Because beam steel 11 is at the bottom of beam end is bent to beam downwards, be convenient to so the interior reserved post reinforcing bar 21 of foundation columns 2 and weld, as shown in Figure 3, downward bent part divides beam steel 11 and post reinforcing bar 21 to be welded in weld 4, node is connected according to firm, and simple to operation.
During construction, first build foundation columns 2, and at the reserved groove 22(of capital as shown in Figure 4), at reserved groove 22, should make its degree of depth identical with the height of precast beam body 1, width is than the wide 5cm～10cm of precast beam body 1, and groove 22 connects foundation columns 2, and the beam steel in foundation columns 2 outsides is left to capital in advance; Then build precast beam body 1, and make that the horizontal section length of the reserved beam steel 11 of precast beam body 1 beam-ends is that beam can bearing length 1/3, lower horizontal section length is curved at the bottom of beam; Again precast beam body 1 is arranged in groove 22, by reserved post reinforcing bar 21 welding of reserved beam steel 11 lower horizontal sections of precast beam body 1 and foundation columns 2 outsides, within the scope of deck-molding by beam steel 11 and post reinforcing bar 21 integral solder; Finally, by the concrete surface dabbing of foundation columns 2 and precast beam body 1, build second stage concrete 3.Compared with prior art, the utility model construction is simple, and connection reliability is good.
