In order to achieve higher shock resistance, the connecting structure of the building has certain shearing resistance and longitudinal tension resistance; the shearing resistance can resist the damage of the horizontal force to the building, and is mainly determined by the strength and the toughness of the building material; the resistance to longitudinal tensile forces is mainly exerted on the connecting structures of the buildings. The traditional building, no matter be brick-concrete structure or integrative pouring formula structure, all adopt reinforcement formula connection structure to strengthen the ability that the building resisted longitudinal tension, the reinforcing bar is buried underground in the building wall, utilizes concrete placement to pour reinforcing bar and building wall and becomes an organic whole, has also improved the ability that the building resisted longitudinal tension when improving wall strength. When the length of the steel bars is not enough, the single steel bars are longitudinally connected into a sufficient length by adopting a binding or welding method. Because the wall body can be built only by binding and welding the reinforcing steel bars on site, the building structure can be constructed only on site, and the industrialized production cannot be realized.

The modularized building structure produced in an industrial manner has the characteristics of high standardization degree, less construction waste, high construction speed, small influence on the surrounding environment and the like.

Detailed Description

The following description of the embodiments is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.

As shown in figure 1 and figure 2, a building assembly structure connecting rod includes tubular main part 1, sets up public head 2, female head 3 at main part 1 both ends respectively, and main part 1, public head 2 and female head 3 adopt metal material integral structure. And the male head 2 and the female head 3 are provided with threads matched with each other. When in connection, the male head 2 at the lower end of the previous connecting rod is inserted into the female head 3 at the upper end of the next connecting rod, and the male head 2 and the female head 3 are locked and connected together through threads by rotating the connecting rods; the connection in sequence can connect a plurality of connecting rods into a whole in the longitudinal direction. The male head 2 is a circular truncated cone coaxial with the main body part 1, and the outer diameter of the top end of the male head is smaller than that of the bottom of the male head, so that the male head is in a regular circular truncated cone shape. The outer wall of the circular truncated cone body is provided with external threads, and the center of the circular truncated cone body is provided with a through hole 4 communicated with the inner cavity of the main body part 1; the female head 3 is a conical counter bore which is coaxially arranged with the main body part 1 and matched with the cone frustum, and an overflow hole 5 penetrating through the pipe wall of the main body part 1 is arranged on the main body part. When the connecting rod is used, a longitudinally arranged mounting hole is reserved in a building wall module, after the wall module is hoisted in place, the connecting rod is inserted into the mounting hole, the male head 2 faces downwards, the female head 3 faces upwards, the male head of the connecting rod is inserted into the female head of the connecting rod at the next layer, and then the connecting rod is rotated to screw threads between the male head 2 and the female head 3, so that the longitudinal connection of the connecting rods at the upper layer and the lower layer is completed; and then high-strength cement is injected into the hole in the center of the connecting rod, the cement overflows to the outside of the connecting rod along the overflow hole 5 after filling the center hole of the connecting rod, and finally cement paste is filled in the inner gap and the outer gap of the connecting rod, and the cement paste with high fluidity can also permeate into the gap on the end face of the building component, so that the effects of pressure equalization and pressure reduction of the cement paste are achieved, the local pressure of the bottom component of the high-rise building is favorably reduced, and the effective load is improved. After the cement paste is dried, the connecting rod is bonded with the wall material, so that higher mechanical strength and connection firmness are achieved.
