Construction site fence connecting beam bottom fixing device

Abstract

The invention relates to construction safety appliances, and discloses a construction site fence connecting beam bottom fixing device. The construction site fence connecting beam bottom fixing deviceincludes a connecting beam, fence poles, and a fixing pole; the inner bottom of the connecting beam is arranged to be a cavity structure and is telescopically connected with a vertical fixing rod; four sets of vertical sliding grooves are equally spaced on the outer side of the middle and lower parts of the fixing rod; the inside of the sliding grooves are slidingly connected with balls; the outside of the balls is connected with an inserting rod with an L-shaped structure with the end facing down in a rolling manner; the straight section of the inserting rod crosses a bottom plate; the insideof the sliding groove is provided with plurality sets of limit grooves at equal intervals from top to bottom; a set of clamping plate is slidingly sleeved on the fixing rod on the upper side of the inserting rod; the position of the clamping plate corresponding to the sliding groove is telescopically connected with a spring rod; the outer end of the spring rod is fixedly installed with a limit plate; and a spring is sleeved on the spring rod located between the limit plate and the outside of the clamping plate. The construction site fence connecting beam bottom fixing device has the advantages of simple operation, adjustable height, high fixability, and is beneficial to popularization and use.

Description

technical field [0001] The invention relates to a construction safety appliance, in particular to a bottom fixing device of a construction site fence connecting beam. Background technique [0002] During the construction process, it is often necessary to set up safety fences to remind construction workers or passersby to pay attention to construction safety. The safety fences currently used are generally fixed on the ground with a certain number of columns, and some ropes are pulled or tied between the columns. , in order to play the role of prompting and intercepting workers or pedestrians. [0003] Chinese Patent (Announcement No.: CN 203160825 U, Announcement Date: 2013.08.28) discloses a connection and combined safety fence for construction sites, comprising a plurality of vertical poles, and the bottom ends of the vertical poles are respectively connected with vertical pole fixing devices. A horizontal rail is connected between two adjacent vertical poles, and connecti...

Problems solved by technology

However, when the fence is in use, the poles are generally directly inserted into the ground, but most of the fences do not take the columns or beams between the fences as the key focus. For simple insertion of the columns into the ground, Whether it is possible to ensure the stability of the column and not tilt or collapse in the case of wind blowing and shaking, this fence also has such problems. Once the connecting column or beam tilts, it will have a great impact on the entire fence, so it needs to be designed A device capable of stably fixing connecting columns or connecting beams between fences
