The purpose of the utility model is realized like this:
an assembly structure node of a prefabricated welded steel bar mesh floor bottom rib comprises a support, a bottom net and an additional rib, wherein a bottom net placing area is enclosed between the support and the support, one end of the additional rib is anchored into the support, and the other end of the additional rib extends into the bottom net placing area; the bottom net comprises transverse steel bars and longitudinal steel bars, the transverse steel bars are arranged along the length direction of the longitudinal steel bars, a welded steel bar mesh is formed at the joint of the transverse steel bars and the longitudinal steel bars by welding, and the bottom net is placed on the bottom net placement area; the additional ribs extending into the bottom net placing area are connected with the bottom net in a lap joint mode, and bottom net steel bar anchoring is achieved. The additional muscle one end is fixed on the support in advance, and the additional muscle other end stretches out towards end net placing area, and during end net installation, only need directly place end net in end net placing area, will attach muscle and end net overlap joint can, compare traditional whole net construction, make end net avoid with other reinforcing bar collisions, the counterpoint is easy, the construction is simple.
The purpose of the utility model can also adopt the following technical measures to solve:
as a more specific scheme, the distance between the transverse additional ribs is not more than 2 times of the distance between the transverse reinforcing steel bars of the bottom net, and the distance between the longitudinal additional ribs is not more than 2 times of the distance between the longitudinal reinforcing steel bars of the bottom net, so that mutual collision between the additional reinforcing steel bars and the transverse reinforcing steel bars and the longitudinal reinforcing steel bars of the bottom net is avoided, and the installation is easier.
More specifically, the area of the base net is not larger than the area of the base net placement region. Because the area of the bottom net is not more than that of the bottom net placing area, the bottom net can be directly placed in the bottom net placing area, and the operation is simple.
More specifically, the additional rib is anchored into the support to a depth of not less than 5d and beyond the center line of the support.
The utility model has the advantages as follows:
the utility model discloses, attach muscle one end and fix on the support in advance, the additional muscle other end is placed the region towards end net and is stretched out, and during end net installation, only need directly place end net in end net places the region, will attach muscle and end net overlap joint can, compare the whole construction of traditional net, make end net avoid colliding with other support reinforcing bars, the counterpoint is easy, the construction is simple.
The utility model discloses, transversely attach the interval that adds the muscle and be not more than 2 times of the interval of the horizontal reinforcing bar of end net, vertically attach the interval that adds the muscle and be not more than 2 times of the interval of the vertical reinforcing bar of end net to avoid attaching muscle, horizontal reinforcing bar and vertical reinforcing bar and collide each other, the installation is easier.

Detailed Description
The invention will be further described with reference to the following drawings and examples:
embodiment, referring to fig. 1 to 9, a bottom net assembly construction node for a floor slab includes a support 1, a bottom net 2 and an additional reinforcement 3, wherein the bottom net 2 includes transverse reinforcements 21 and longitudinal reinforcements 22, the transverse reinforcements 21 are arranged along the length direction of the longitudinal reinforcements 22, the distance between the transverse reinforcements 21 is S1, the distance between the longitudinal reinforcements 22 is S2, and the joints of the transverse reinforcements 21 and the longitudinal reinforcements 22 are welded to form welded reinforcement meshes.
A bottom net placing area 4 is defined between the support 1 and the support 1, the area of the bottom net 2 is not larger than that of the bottom net placing area 4, one end of the additional rib 3 is fixed in the support 1, the other end of the additional rib 3 extends into the bottom net placing area 4, the distance between the additional rib 3 and the additional rib 3 is S3, the distance between the additional rib 3 and the additional rib 3 is not larger than 2 times of the distance between the bottom net and the steel bars in the same direction, namely S3 is not more than 2S2 or S3 is not more than 2S 1.
