Abstract
A joint of semi-precast beam of the utility model is arranged on the lateral side with a convex extending concrete block whose inner has a plurality of reinforcing steel bars. A plurality of lower layer reinforcing steel bars inside the concrete block extend through to outer a distance from the concrete block end and is bent. Hoop bars inside the concrete block extend to upper section a distance. The central place of the joint of the semi-precast beam is provided with a plurality of predetermined through-holes. The utility model has the advantages of saving cost and avoiding complex joint construction.
Description
Technical field
The utility model relates to a kind of building unit, relates in particular to a kind of half precasting column beam joint of saving cost, exempting joint construction complexity.
Background technology
Beam, the post of reinforced concrete structure (RC), concrete wherein mainly are to be used for resistance to compression, and reinforcing bar is for tension and bears shearing, so that concrete structure can bear seismic forces and load-carrying.
With precasting construction method construction of buildings the time, when especially being positioned at the precast pole of desiring on the precast pole of bottom in conjunction with several precasting beams and a top, it is in the beam column joint several bars of precast pole (vertically) and each precasting beam (laterally) setting that protrudes out that staggers, behind the envelope mould in column beam joint concrete perfusion fixed.But, above-mentioned when being configured in actual use, there is following shortcoming:
Above-mentioned when being configured in the staggered beam column main reinforcement laterally and longitudinally in column beam joint place, has construction than complexity and because of the too small shortcoming that does not allow to occur any operational error of headspace, when meeting the more design of number of steel bars configuration, more can be too much because of the number of steel bars of column beam joint, can't stagger and necessary size of amplifying beam column inadequately in the space, so waste material does not meet economic benefit, necessity of being improved is arranged in fact.
The utility model content
In order to overcome the complicated shortcoming of existing precasting column beam joint construction, the utility model provides a kind of half precasting column beam joint, and it has the advantage of saving cost, exempting joint construction complexity, and further accelerating construction progress.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of half precasting column beam joint, it is characterized in that, half precasting column beam joint lateral location protrudes out and is provided with the concrete block that inside has several bars, stretch through by concrete block inside and to be provided with several lower floors reinforcing bar to the outside, the outer end of each lower floor's reinforcing bar protrudes out a segment distance and bending by the concrete block end, stirrup extends to its top one segment distance by concrete block inside, and half precasting column beam joint centre is provided with several default through holes.
Aforesaid half precasting column beam joint wherein is provided with a convex surface above the central authorities of half precasting column beam joint, bury top reinforcement in the convex surface in advance underground, by protruding out a segment distance around the convex surface.
Aforesaid half precasting column beam joint, wherein central authorities' four edges of half precasting column beam joint are respectively equipped with several default through holes.
Aforesaid half precasting column beam joint, wherein half precasting column beam joint is cross by outstanding concrete block around the mediad.
The beneficial effects of the utility model are, it has the advantage of saving cost, exempting joint construction complexity, and further accelerating construction progress.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the exploded perspective schematic diagram of the utility model first embodiment.
Fig. 2 is the assembled sectional view of the utility model first embodiment.
Fig. 3 is the exploded perspective schematic diagram of the utility model second embodiment.
Fig. 4 is the assembled sectional view of the utility model second embodiment.
The number in the figure explanation:
10 half precasting beam splices
11 concrete blocks
12 lower floor's reinforcing bars, 13 stirrups
14 through holes, 15 convex surfaces
16 top reinforcementes, 20 precast poles
21 reinforcing bars, 30 precast poles
31 steel bar connectors, 32 non-shrink mortars
The specific embodiment
See also Fig. 1, shown in Figure 2, the lateral location of the utility model half precasting column beam joint 10 protrudes out the concrete block 11 that is provided with inner several bars, half precasting column beam joint 10 is by outstanding concrete block 11 around the mediad and be cross, stretch through by concrete block 11 inside and to be provided with several lower floor's reinforcing bars 12 arranged side by side to the outside, the outer end of each lower floor's reinforcing bar 12 is to protrude out one section suitably distance and bending by concrete block 11 ends, and stirrup 13 is to extend to the one section suitable distance in its top by concrete block 11 inside.
The central authorities' outside four edges at half precasting column beam joint 10 are respectively equipped with several default through holes 14, and each through hole 14 is respectively upper and lower perforation half precasting column beam joint 10.
During use (as shown in Figure 1 and Figure 2), the utility model mainly is to protrude out several bars 21 on the set precast pole 20 in bottom, each root reinforcing bar 21 correspondence respectively wears and enters in the through hole 14, and pass through hole 14 up, insert several pre-buried in set precast pole 30 bottoms, top steel bar connector 31 inside again, pour into non-shrink mortar 32 at through hole 14, steel bar connector 31 and gap location between the reinforcing bar 21 again and combine fixing.Lower floor's reinforcing bar 12 in the utility model can be respectively with the precasting beam (not shown) in the outside on set reinforcing bar (not shown) combine and fix with concrete, stirrup 13 can be respectively with beam top reinforcement and floor (not shown) on set reinforcing bar (not shown) combine and fix with concrete, because the complexity when the utility model can be exempted the joint construction has cost-effective advantage.
As shown in Fig. 3, Fig. 4, be another embodiment of the utility model, half precasting column beam joint, 10 structures most of with shown in Figure 1 are identical, its difference be in: above half precasting column beam joint, 10 central authorities, protrude out and be provided with the convex surface 15 of a height a little more than concrete block 11 height, be embedded with in the convex surface 15, by stretching out and along the top reinforcement 16 of concrete block 11 directions, the height of these convex surface 15 end faces is the height of floor finished surface the side, during use, also have and aforesaid effect.
The utility model is desired to reach topmost purpose and is: half precasting column beam joint 10 is arranged on the precast pole 20 of lower floor, the reinforcing bar 21 that passes on the precast pole 20 of lower floor penetrates half precasting column beam joint, 10 default several through hole 14 inside that form, reinforcing bar 21 penetrates in several pre-buried in precast pole 30 bottoms on upper strata steel bar connectors 31, and is fixing with non-shrink mortar 32 combinations again.The lateral location of half precasting column beam joint 10 is provided with lower floor's reinforcing bar 12 and stirrup 13, lower floor's reinforcing bar 12 combines fixing respectively with the precasting beam (not shown) in the outside, stirrup 13 can combine fixing respectively with beam top reinforcement and floor, reach to save cost and exempt joint construction complexity purpose.
In sum, the utility model is with quite simple space structures form, reaches the purpose of complexity when saving cost and exempting the joint construction, has the value of industry, and has novelty, creativeness, practicality, so file an application in accordance with the law.
