A self-adjusting built-in embedded joint and its embedded method

Abstract

The invention disclosed by the invention belongs to the technical field of electric well bridges, and specifically relates to a self-adjusting pre-embedded section of a building and a pre-embedded method thereof. The technical solution thereof is to include a bridge, the bridge is provided with a second through hole, and further includes: The butt plate of the bridge frame can be detachably connected; and the embedded joints of the bridge frame can be detachably connected; The connecting component or the fourth connecting component is connected, and the beneficial effect of the present invention is: by splicing the first splicing plate and the second splicing plate into a pre-embedded piece, the splicing structure between the first splicing plate and the second splicing plate is novel and ingenious, Fast splicing can be achieved, and it is easy to disassemble, which is convenient for inspection and maintenance of the cables inside the docking. The connecting piece and the bridge frame are connected through the first connecting component, and the plug in the first connecting component is located in the slot of the plug and is not exposed Outside, avoid the screws scratching the cables.

Description

technical field [0001] The invention relates to the technical field of electric shaft bridges, in particular to a self-adjusting building pre-embedded section and a pre-embedded method thereof. Background technique [0002] Cable trays are divided into trough type cable trays, tray type cable trays, stepped cable trays, grid trays and other structures, which are composed of brackets, support arms and installation accessories; they can be erected independently or laid in various buildings and pipes. On the gallery bracket, it reflects the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized and installed in the open air bridge outside the building. If it is near the sea or belongs to the corrosion area, the material must be It has the physical properties of corrosion resistance, moisture resistance, good adhesion and high impact resistance. [0003] The embedded section of the existing e...

Problems solved by technology

[0005] For this reason, the present invention provides a self-adjusting built-in joint. By setting the built-in joint as the first splicing plate and the second splicing plate, and connecting them through the third connecting component, it is convenient to remove the built-in joint. , the pins connecting the bridge frame and the docking plate are inserted into the slots of the plug caps, and are not exposed outside, and the embedded joints are connected to the bridge frame through the second connecting component or the fourth connecting component, so that the embedded joints are elastically fixed and have an anti-seismic effect , to solve the problem that the pre-embedded joints of the existing electric well bridge passing through the floor are hollow tubes welded by four identical plates. When the bridge needs to be maintained and replaced, it is not convenient to remove the pre-embedded joints, making maintenance inconvenient ; and there are protruding screws on the inner wall of the bridge, which is easy to scratch the cable when the cable is laid; and the embedded joints are fixed by bolts, so that the embedded joints do not have anti-seismic performance. When shaking or earthquakes occur, the embedded joints are easy to move The position makes the pre-embedded section unstable and damages the cable
