End, another connection box are placed at the node of prefabricated post, and two connection boxes are bolted by connecting box, each to connect the upper of box
Portion is equipped with reserved grout hole.
Further, the quantity of the connection box on the precast beam is consistent with vertical muscle quantity, and one end of every vertical muscle passes through
The other end of one connection box, vertical muscle extends to one end of precast beam;And each connection box has matched reserved grout hole, in advance
Grout hole is stayed to be through to the top of connection box;Wherein the connection box of side is placed on the lowest part of precast beam, the connection of the other side
Box is embedded at the node of prefabricated post, and the connection box of two sides keeps horizontal.
Further, the T-steel is at least 4, is embedded in prefabricated post, and T-steel is on the left and right directions of prefabricated post
Stretching prefabricated post is symmetrical, and the quantity of angle steel bolt and the quantity of T-steel are identical.
Further, hole matched with the pre-buried through-hole of beam-ends is equipped on the lateral edge of a wing of angle steel and T-steel;?
Longitudinal edge of a wing of angle steel is equipped with the hole with angle steel bolt matching, and the length of hole is greater than angle steel spiral shell on longitudinal edge of a wing of angle steel
The diameter of bolt.
Further, the L v notch v depth is the top for there be not connection bolt just, and the depth of U-shaped breach is not have just
The top of angle steel bolt is crossed, and L v notch v and U-shaped breach constitute a plane at node.
The benefit of the utility model is with advantage: early period, whole dry type connected, and without welding, principle is simple at scene, installation
Convenient, connection is reliable, good integrity, avoids wearing muscle in work progress, it is insufficient to efficiently solve prefabricated member shear resistance
Problem, and construct and terminate upper back not there are construction trace, neat appearance can also protect top steel not to be corroded.

Embodiment
As shown in figs. 1-7, a kind of novel precast concrete bean column node, the bean column node need to prepare precast beam 1, prefabricated
Column 2, angle steel 3, connection bolt 5 and connection box bolt 10.
As shown in Fig. 2, the production for precast beam 1, needs the position selection of the pre-buried through-hole 6 of beam-ends, reserved grout hole 7
And arrange, it needs the deployment scenarios of the vertical muscle 8 of basis to carry out the connection box 9 in left side pre-buried, guarantees that vertical muscle 8 extends to beam-ends, and
And hole of the row to pass through connection box bolt 10 is reserved on precast beam 1.
As shown in Figure 3 and Figure 4, for the production of prefabricated post 2, main is to need to carry out on angle steel bolt 4 and T-steel 13
Pre-buried, the distance that angle steel bolt 4 stretches out the U-shaped breach 12 in prefabricated post 2 is unsuitable too long, and the pre-buried of T-steel 13 is to guarantee that it is anti-
Cut the essential step of ability.The depth of L v notch v 11 and U-shaped breach 12 was not there to be the most top of connection bolt 5 and angle steel bolt 4 just
End is advisable, and L v notch v 11 and U-shaped breach 12 may be constructed a plane at node.
As shown in figure 5, the quantity of the connection box 9 on precast beam 1 is consistent with vertical 8 quantity of muscle, the connection box 9 in left side is pre-buried
It is embedded at the node of column in the connection box 9 of beam-ends, right side, the connection box 9 of two sides keeps horizontal, and to avoid as far as possible and beam
Pre-buried through-hole 6 is held to intersect.Each connection box 9 has matched reserved grout hole 7, reserves grout hole 7 through connection 9 top of box
Precast beam 1 or prefabricated post 2 node at.
As shown in Figure 6 and Figure 7, for the production of angle steel 3, it should be noted that the hole lengths on the vertical edge of a wing are greater than pre-embedded bolt
4 diameter, angle steel 3 can not be installed caused by avoiding because of production error.
A kind of novel precast concrete bean column node, construction method are as follows:, will be pre- after scene installs prefabricated post 2 in place
1 vertical lifting of beam processed is simultaneously placed on T-steel 13, and connection bolt 5 is penetrated after angle steel 3 is placed in place and is fixed, by angle steel spiral shell
Bolt 4 and connection box bolt 10 are fixed, and complete preliminary installation.Support mold pouring mortar is then carried out, uses sand for having the gap
Slurry or concrete fill up, and conserve and complete whole installations.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
