Problems solved by technology

In addition, the distance between the tower crane and the building is different in different construction sites, and the specifications are different. The tower crane attached to the wall can only be cut and welded. This method is difficult to achieve the design strength of the welded part, and it cannot be reused, resulting in waste of materials, which does not meet the current green construction standards. Require

Embodiment Construction

[0051] The present invention will be specifically described below with reference to specific embodiments.

[0052] like Figure 1-17 As shown in the figure, a prefabricated concrete high-rise residential tower crane is installed with a wall rod device for energy dissipation and vibration reduction. The wall rod device includes an assembly end 10, an assembly end 20, a connecting piece 30, an inner core material 40, and a connecting square tower 1. 50. The connecting square tower 2 60, the connecting conversion piece 1 70, the connecting conversion piece 2 80 and the connection fixing piece 90 which is detachable and matched with the reserved connecting parts of the building; the assembly end 10 and the assembly end 20 pass through the connecting piece 2 30 constitutes a detachable fit, the first assembly end 10 and the second assembly end 20 have gaps; the inner core material 40 is arranged in the gap between the first assembly end 10 and the second assembly end 20 for frictio...

Abstract

The invention belongs to the technical field of prefabricated buildings, and specifically relates to an energy-dissipation and vibration-absorbing type wall-attached rod device of a tower crane for a prefabricated concrete high-rise residential building. The device comprises a first prefabricating end, a second prefabricating end, a second connector, an inner core material, a first connecting square tower, a second connecting square tower, a first connecting switching part, a second connecting switching part and a connecting fixing part. With the adoption of the wall-attached rod, the problem of prefabricating, combining and connecting of a prefabricated wallboard of the prefabricated concrete high-rise residential building and the tower crane under different distance can be solved; the impact of the wall-attached rod to the wall body and the compressive fatigue under the wind-induced vibration and earthquake effects can be reduced; the damage of the wall-attached rod of the tower crane to the wall of the residential building can be avoided; a reliable, easy-dismounting, replaceable and random-combined wall-attached rod connecting device is provided to ensure the safe operation of the tower crane during the construction of the prefabricated concrete high-rise residential building; the device can be widely applicable to the connecting of the tower crane of the prefabricated concrete high-rise residential building and has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of prefabricated buildings, and in particular relates to a prefabricated concrete high-rise residential tower crane energy dissipation and vibration damping wall-attaching rod device. Background technique [0002] With the rapid development of construction industrialization, prefabricated concrete high-rise structures have been widely used in residential buildings. During the construction of prefabricated concrete high-rise residential buildings, tower cranes are required to transport building materials to construction sites and construction platforms. Tower cranes have become a must for high-rise building construction. Essential equipment. There are three types of tower cranes: external attachment, internal attachment and external hanging. The connection between the tower crane and the prefabricated concrete high-rise residential building has become a key factor in the safe construction of the tower crane. ...
