Circular tube guardrail connecting component and circular tube guardrail

Abstract

The invention discloses a circular tube guardrail. The circular tube guardrail is fixed on vertical columns on two sides or on a wall by a plurality of transverse railing circular tubes via connecting components. A middle vertical plate of the connecting component connects a top arc portion and a bottom arc portion, the outer diameter of the top arc portion and the bottom arc portion is in clearance fit with the inner diameter of the circular tubes, fixing holes are reserved on the vertical plate, connecting holes are reserved on the bottom arc portion, and central axes of the connecting holes penetrate through an arc center and form included angles with a plumb line. The circular tube transverse rails are mounted on the vertical columns on the two sides via the internally hidden connecting components, tube fitting sectional bars are directly used as the circular tubes and are excellent to hold, good in user feeling, convenient to obtain and low in cost. The connecting component is good in rigidity, strong in bearing capacity and high in safety. By rotating each of the circular tubes by a certain angle, a fastening position can be rotated to the angle not easy to see by observers, so that attractive and elegant appearance is realized while requirements on convenience and quickness in assembling are met, grade of products is greatly improved, and product competitiveness and customer satisfaction are effectively improved.

Description

technical field [0001] The invention relates to the field of building components, in particular to a circular tube guardrail connection component and a circular tube guardrail. Background technique [0002] Chinese national standards GB50096-2011 "Residential Design Code", GB50352-2005 "Civil Building Design Code" and other standards have mandatory requirements for installing safety guardrails in front of balconies and floor-to-ceiling windows. At the same time, real estate developers also have simple installation and beautiful appearance , connecting screws are not visible and other requirements. In the prior art, a pre-embedded part is usually fixed on the wall or column first, and then the two ends of the circular pipe rail are spot-welded on the pre-embedded part, and then a collar is used to cover the welded part, but this method not only An electric welding machine is required during assembly, which is cumbersome and complicated, and the appearance is not beautiful, a...
