Description
Technical Field
The invention relates to the field of building construction, in particular to a butt joint hinge structure of two adjacent net hanging rods of a falling object protection net.
Background
In the construction process of high-rise buildings, a horizontal protective net for receiving falling objects is required to be additionally arranged on the outer side of the scaffold along a certain height. Usually, the protective net is a large mesh net body formed by weaving fiber ropes in a staggered manner, and the periphery of the large mesh net body is connected with a steel pipe and accessories thereof.
Because the risk of the operation of erecting the horizontal protective net outside the scaffold is higher, and according to the higher requirement of the protection enhancement of the falling object protective net, the common large-mesh net body needs to be changed into the falling object protective net with stronger bearing force, the weight of the falling object protective net and the erecting area of the falling object protective net are correspondingly increased, and the risk is higher undoubtedly by adopting the traditional protective net erecting mode.
To solve this problem, we consider improving the way of building a rack by assembling the falling object protection net and its net hanging rod in the floor or in the rack, and then extending it outward in the horizontal direction until it reaches a predetermined position. However, because the area and the weight of the novel falling object protective net support are large, the falling object protective net located on the side face of the same building is difficult to be expanded outwards at one time. Therefore, we further consider that the falling protection net is expanded outwards in sections, which requires that the butt joint connection between two adjacent net hanging rods of the external net cannot be a rigid connection, but should be a flexible connection, i.e. the adjacent net hanging rods need to be capable of bending and can adapt to the sliding of the axial length of the net hanging rods, so that the outward expansion of the falling protection net in sections can be realized. In order to meet the requirement of the working condition, a butt joint hinge structure of two adjacent net hanging rods of the falling object protection net needs to be designed.
Disclosure of Invention
In view of the defects of the prior art, the invention provides a butt joint hinge structure of two adjacent net hanging rods of a falling object protection net, which can realize flexible connection between the two adjacent net hanging rods, so that the two adjacent net hanging rods can be flexibly bent and can be deformed in a certain telescopic way to avoid interference.
The technical scheme of the invention is as follows: a butt joint hinge structure of two adjacent net hanging rods of a falling protection net comprises a first hinge joint, a second hinge joint and a third hinge joint which are hinged to a hinge shaft simultaneously, wherein a telescopic sleeve is sleeved on a rear sleeve of the first hinge joint, the rear end of the telescopic sleeve is connected with a first external pipe, a reset spring is further connected between the rear sleeve of the first hinge joint and the first external pipe, the front end of the reset spring is fixed on the rear sleeve of the first hinge joint, and the rear end of the reset spring is fixed on the first external pipe; the rear portion of the second hinged joint is provided with a second external sleeve, the first external sleeve and the second external sleeve are respectively connected with two adjacent net hanging rods, the rear portion of the third hinged joint is provided with a third external sleeve, and the third external sleeve is connected with the end portion of an external support rod of the falling object protection net.
Preferably, the pipe diameter of the telescopic pipe is smaller than that of the rear sleeve of the first articulated joint, so that the telescopic pipe can move back and forth along the inside of the rear sleeve of the first articulated joint, and telescopic change of the distance between the first articulated joint and the first external connecting pipe is realized.
Preferably, the front end of the return spring is fixed on the outer wall of the rear sleeve of the first articulated joint, and the rear end of the return spring is fixed on the outer wall of the first outer joint pipe.
Preferably, the first external connecting pipe and the second external connecting sleeve are respectively connected with the net hanging rod through two bolts which are longitudinally and transversely staggered with each other.
Preferably, the third external sleeve is connected with the end part of the external stay bar through two bolts which are staggered longitudinally and transversely.
The invention has the advantages that: according to the invention, the first hinge joint, the second hinge joint and the third hinge joint which are simultaneously hinged on the same hinge shaft are used for realizing flexible butt joint of two adjacent net hanging rods, the third hinge joint is connected with the end part of the outer support rod of the falling object protection net, when the outer support rod is pushed outwards, the two adjacent net hanging rods can be bent around the hinge shaft, and the first hinge joint is also provided with the telescopic mechanism, so that the problem of mechanical interference caused by the change of the axial lengths of the two net hanging rods due to bending deformation can be buffered under the condition that the two net hanging rods synchronously move forwards, and the falling object protection net is favorably expanded outwards in sections. .
