Tie device

Abstract

The invention discloses a tie device. The tie device comprises a plate clamp, an adjusting clamp and a connector, wherein the plate clamp is detachably connected with the wall of a door / window entrance of an existing building; the adjusting clamp is connected with the plate clamp and is used for adjusting the clamping force between the plate clamp and the wall; and the plate clamp is fixedly connected with a scaffold through a connector. The tie device is suitable for the tying of the scaffolds outside the existing buildings and the outer walls, and is particularly suitable for the existing buildings, the outer walls of which have protection requirements and values; and the wall of the door / window entrance is utilized and is clamped and fixed by adoption of the plate clamp, so that the decoration layer and structural layer of the outer wall are prevented from damage, the rigidity is good, a hole filling process is not required and then no hidden danger such as water seepage is caused.

Description

Technical field [0001] The invention relates to the technical field of building facade construction, in particular to a tie-in device. Background technique [0002] The main function of the scaffold tie device is to connect the scaffold body to the main structure of the building, which can strengthen the overall stability of the scaffold and improve the load-bearing capacity of the scaffold, thereby avoiding major safety accidents such as overturning or collapse of the scaffold. [0003] At present, the commonly used tie-in methods for external walls can be summarized into two types: pre-embedded method and post-anchor method. The pre-embedding method is only suitable for new structures. Before pouring concrete, embed parts, steel pipes, steel bars, etc. in the outer wall. The advantages of the pre-embedding method are good rigidity and accurate burying position, but this method is expensive and troublesome to disassemble , The dismantled hole shall be sealed later. The post-anch...

Problems solved by technology

The pre-embedded method is only suitable for new structures. Embedded parts, steel pipes, steel bars, etc. are pre-embedded on the outer wall before pouring concrete. The advantages of the pre-embedded method are good rigidity and accurate embedding position, but this method is costly and troublesome to disassemble. , the dismantled hole needs to be sealed in the later stage

The post-anchoring method is applicable to both new and old building structures. The principle is to drill holes on the side of the wall, install expansion anchors or chemical anchors, and then connect them with anchor plates welded together with steel pipes in advance. The advantage is good rigidity. , There is no hole filling process, so there is no hidden danger of water seepage, but this method needs to make holes in the outer wall, destroy the outer wall, and after the construction is completed, the anchor bolts cannot be reused and the cost is high

[0004] The above two methods are suitable for newly-built exterior walls or buildings with low protection requirements for exterior wall finishes, while for existing buildings, especially historical buildings that need to be protected (whose facades have certain value or have a history that requires protection) building), the above two methods are no longer applicable
