Description

Protective connecting structure of metal protective net attached to lifting operation safety protective platform

Technical Field

The utility model relates to a connection structure that is used for carrying out all-round protection to construction with adhesive type lift operation safety protection platform's safety protection network.

Background

The construction of high-rise and super high-rise buildings is widely popularized in cities, and the construction equipment and the construction mode are continuously updated. At present, the construction of high-rise and super high-rise buildings mostly adopts a suspended lifting operation safety protection platform (namely, an original 'attached lifting scaffold') controlled by a group machine to replace the traditional construction mode of setting up a floor fixed scaffold at full height, namely, the attached lifting operation safety protection platform is installed to be not more than 5 floors, and the scaffold is suspended to be gradually lifted for construction along with the increase of building floors. The appearance of the safety protection platform for attached lifting operation realizes the leap from static to moving of the scaffold, and the maximum characteristics and advantages of the safety protection platform are energy saving and environmental protection, so that the safety protection platform has great economic value, and although the building floor is built to be higher, the saving advantage is more obviously embodied.

The attached lifting operation safety protection platform is generally composed of a scaffold frame body structure with 4-5 floors of height, a corresponding lifting system, an anti-falling system, an anti-inclining system, a synchronous control system, a floor stopping system, a safety protection system and the like. Because the construction of attaching to lift operation safety protection platform adopts the mode of crowd's machine operation unsettled lift to replace the unsettled operation of the scaffold frame body that needs to set up full-height floor height with 4 ~ 5 floor height's support body, therefore the safety protection system is one of them key and important part.

The safety protection facilities of the traditional attached lifting operation safety protection platform generally adopt a flexible high-density polyethylene dense mesh safety net, and the safety net is poor in impact resistance, so that the safety net is gradually replaced by a safety net made of metal materials such as a punched steel plate net and the like at present. In order to solve the problems of rigid connection modes such as iron wire binding connection, half-side buckling connection and bolt direct connection which are conventionally adopted between the steel plate net and the attached lifting operation safety protection platform frame body, a connection structure of the attached lifting operation safety protection platform safety protection net is reported in the Chinese patent application of CN109779276A, and the connection structure is a structural member with a U-shaped clamping space, is clamped and matched with a transverse bearing and hanging structure such as angle steel and the like which are used for bearing and hanging the safety protection net in the outer vertical surface of the attached lifting operation safety protection platform, and is fastened and connected with a transverse beam frame of the safety protection net. In practice, the flexible moving range of the protective net is only limited in the inner-outer one-dimensional direction, and the protective net hardly has the moving range in the left-right direction and/or the up-down direction, and the external force impact on the protective net can come from any direction in practice due to different factors in the construction process, so the effective flexible deformation range of the protective net is limited, and the omnibearing protection cannot be realized. On the other hand, there is a room for improvement in installation and use in actual construction. For example, if the frame body bearing member attached to the lifting operation safety protection platform is not angle steel or the installation direction of the angle steel is not consistent with the prompting direction, the installation of the angle steel is also difficult.

SUMMERY OF THE UTILITY MODEL

And the inner vertical surface stop block is provided with a corresponding connecting structure such as a bolt connecting hole and the like for being mutually fixed with an attached lifting operation safety protection platform (comprising a vertical rod or a cross rod). The heights of the outer vertical surface check block and the inner vertical surface check block are not lower than the height of the transverse supporting beam or the supporting frame of the protective net in the vertical direction, so that the protective net and the transverse supporting beam or the supporting frame thereof in clearance fit in the groove-shaped clamping structure can be effectively prevented and avoided, and the possibility of accidents caused by the fact that the protective net and the transverse supporting beam or the supporting frame thereof are taken out of the groove under unexpected conditions can be avoided.

The specific form of the groove-shaped clamping-shaped structure body with the cross section shaped, which is formed by the outer vertical surface stop block, the inner vertical surface stop block and the bearing block connected to the bottom of the structure, can be selected in various ways.

Test results show that the clamping distance between the outer vertical surface baffle block and the inner vertical surface baffle block in the structure and the accommodating fit clearance between the protective net and the transverse supporting beam or the supporting frame can meet the requirement under the control within the range of 1-3 mm under normal conditions.

During construction, the connecting structure in the structural form is generally preferentially used for connecting the metal protective net of the attached lifting operation safety protection platform arranged as the bottom layer. On the basis of the structure, a limit stop extending downwards is further arranged below the outer vertical face stop in the structure, so that when the limit stop is used for connecting the metal protective net of the non-bottommost attached lifting operation safety protection platform, the limit stop extending downwards has a stop function and can limit the position above the lower protective net, and the protection safety is favorably improved.

The utility model discloses above-mentioned protective connection structure who adheres to operation safety protection platform metal protection network's that goes up and down uses the installation very simple and convenient, and application scope is extensive, does not receive any restriction, with bolt or other suitable connected mode with in it facade dog and firm connect in the support pole setting or the horizontal pole that adhere to operation safety protection platform after, with corresponding protection network direct card put the bearing in the cell type centre gripping space between facade dog and interior facade dog can. In the construction process, no matter the metal protective net of the safety protection platform for the attached lifting operation suddenly receives the impact external force from any direction, because the groove-shaped clamping space in the protective connecting structure of the utility model can limit the protective net to keep stable, but not be positioned on a fixed position, but can move in the groove-shaped clamping space in a single or composite front/back, left/right and up/down proper range, the impact external force received in different directions can be more effectively buffered and rapidly diffused and transmitted to the frame body of the safety protection platform for the attached lifting operation, the buffer capability of all-round impact external force impact resistance in the up-down, left-right and inside-outside three-dimensional directions is improved, the safety is ensured and improved, especially, once a person accidentally falls and impacts the safety protective net, the all-round buffer function in the three-dimensional direction is more favorable for reducing the injury caused by impact, the safety is improved.
