Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Fig. 1-Fig. 7, a kind of steel-concrete combination precast beam and prefabricated post connection structure of the utility model, packet
Precast beam unit 11 and precast column unit 12 are included, precast beam unit 11 is U-shaped steel-concrete structure, and in precast beam unit 11
Reinforcing bar 8 in interior setting beam, as shown in Fig. 4 (b) and Fig. 5.Precast column unit 12 is reinforced concrete structure, is axially inside set
Reinforcing bar 13 in more columns is set, as shown in Figures 2 and 3；U-shaped steel in precast beam unit 11 is stretched out from 11 end of precast beam unit,
The U-shaped steel bottom of 11 end of precast beam unit is stretched out without bottom plate, and the connection edge of a wing 3 in strap bolt hole is arranged in U-shaped steel end.As one
Embodiment is planted, the U-shaped steel inner wall even distribution in precast beam unit 11 there are multiple anchoring keys 2, as shown in Fig. 4 (a)-Fig. 4 (c).Make
For another embodiment, the U-shaped steel surface in precast beam unit 11 is evenly equipped with ripple 5, as shown in Fig. 5 (a) and Fig. 5 (b).It is more
U-shaped steel phase after each one end of a precast beam unit 11 rides on the same precast column unit 12, in opposite precast beam unit 11
Connection reinforcing bar 9 is provided in the region of connection.
As shown in Figure 2 and Figure 6, for right-angled intersection beam type structure is arranged, each one end of four precast beam units 11 is ridden over together
After on one precast column unit 12, one pair of them by the connection edge of a wing 3 and connect with respect to the U-shaped steel in precast beam unit 11 in end
