Background technique

With the advancement of the urban process, the contradiction of decreasing land for urban construction has become more prominent, and super high-rise buildings have developed rapidly due to the advantages of less land use, low urban infrastructure costs, and the ability to improve the appearance of the city.

With more and more super high-rise buildings in modern engineering projects, the difficulty and quality requirements of construction technology are constantly increasing, and the complexity and difficulty of construction technology management are also getting higher and higher. Safety protection is an important management content in construction engineering, especially when performing exterior decoration, due to the limitation of geographical location and construction site, safety protection has become a major problem for super high-rise buildings. Falling prevention objects for exterior wall construction Protection, such as when the outer wall is facing the street, in the prior art, a temporary roof is generally chosen to be erected on the street. However, although the temporary roof solves the problem of safety protection for falling objects, it also has social impacts such as occupying a lot of passage space and affecting the city appearance.

Contents of the invention

Aiming at the prior art proposed above, a temporary roof is usually chosen to be erected on the street, but although the temporary roof solves the problem of safety protection for falling objects, it also has problems such as occupying a lot of passage space and affecting the city appearance, etc. The present invention provides A supporting structure of an outer protective net and a construction method of the outer protective net. The supporting structure and the construction method do not occupy the space of the lower side passage of the outer wall, and at the same time do not cause damage to the building.

The present invention provides a supporting structure for an outer protective net and a construction method for the outer protective net to solve the problem through the following technical points: an outer protective net supporting structure includes a protective net and a mounting frame, and the mounting frame includes a support frame and is fixed on A strut on the support frame, the strut protrudes outward from one side of the support frame, there are at least two mounting frames, and the height of the support frame on each mounting frame can be adjusted;

The struts on each mounting bracket are used to provide support for the protective net.

Specifically, the support frame is used as a connection between each installation frame and the building. In this solution, by setting the height of each support frame to be adjustable, the purpose is to achieve the following purposes: the protective net support structure provided by this solution is , installed in the interior of the building, the height of the support frame can be adjusted to adapt to the height of the two adjacent floors of the building, that is, the height of the support frame is adjusted according to the story height, so that the lower end of the support frame is supported on the lower floor On the upper surface of the upper floor, the upper end interacts with the lower surface of the upper floor, so that each support frame can be clamped between two adjacent floors, and the struts can be protruded from the windows of the building for protection. The functional protective net is erected on the pole. In this program, there are at least two mounting frames, so that each supporting frame can be installed at a reasonable location of the building, such as installing each mounting frame in different rooms facing the same window opening on the same floor, each mounting frame on each mounting frame After the struts protrude from the windows of the corresponding rooms, a protective net fixing frame protruding relative to the building wall can be obtained, that is, the fixing frame is composed of a plurality of struts.

In this scheme, since the adoption of this scheme does not require openings such as expansion bolt holes on the building, this scheme will not cause damage to the building; the installation of this scheme utilizes the space between the building floors, so This scheme does not affect the traffic capacity of the lower passage of the building; since the height of the above installation frame is adjustable, when the supporting structure is used in different buildings or between different floors of the same building, when the floor height changes When adjusting the height of the installation frame, the structure can have a good support ability for the protective net, that is, the scheme also has the characteristics of strong versatility.

A further technical solution is:

As a specific implementation of the support frame: the support frame includes a plurality of vertical rods and a plurality of connecting rods, and the connecting rods are used as intermediate connectors between the vertical rods to realize the mutual restraint between the vertical rods. At least one of the two ends of the bottom end and the top end is provided with a first telescopic part, and each first telescopic part protrudes outward relative to the end of the vertical pole where it is located, and the extension length of the first telescopic part is adjustable. In this solution, the first telescopic part is provided on at least one end of each vertical rod, so that the length of the vertical rod and the first telescopic part can adapt to the floor height value of the building, that is, when the support structure is in use, each vertical The rods are arranged between any adjacent two floors of the building. Among the two ends of the combined rods formed by each vertical rod and the corresponding first telescopic part, the lower end is supported on the upper surface of the lower floor, and the upper end and the lower surface of the upper floor are connected to each other. At the same time, since there are multiple vertical poles and the multiple vertical poles are equivalent to being connected as a whole by connecting rods, in this way, when there is a falling object on the protective net, it can effectively ensure that the support frame has sufficient stability to ensure that the protective net has a stable protection ability. At the same time, in this solution, the support frame is equivalent to being composed of multiple rods. The support frame is not only light in weight, but also has strong structural stability. At the same time, it is convenient to transfer each rod and pass through a narrow space such as a door frame.

In order to prevent the ends of the combined rods from causing excessive local stress on the building, it also includes first pads whose number is twice the number of uprights; the first pads are all wooden blocks. When the support structure is in use, a first spacer is arranged between the end of the combined rod and the floor, so that the interaction area between the building and the support frame can be increased. By setting the above first block as a wooden block, the characteristics of the soft and rough surface of the wooden block itself can be used to increase the friction between the support frame and the building, so that the support frame is subjected to the force brought by the falling object. When the impact force occurs, its position in the building will not be affected by the above impact force; at the same time, in the process of extending the first telescopic part, the characteristics of easy deformation of the wooden block can be used, so that the building will not be damaged due to excessive force. Large surfaces are damaged.

As a person skilled in the art, the above first telescopic part can use hydraulic cylinders, pneumatic cylinders, etc., but the above implementations all require the installation and commissioning of the support structure and other auxiliary equipment, such as gas cylinders, compressors, oil pumps, etc. As a solution with simple structure, convenient installation and debugging, and low manufacturing, use, and maintenance costs, each vertical rod is a circular steel pipe, and the two ends of each vertical rod are provided with first telescopic parts. All are threaded rods that are threadedly connected to the corresponding vertical rods, and each threaded rod is threadedly connected with a locking nut. In this solution, the extension length adjustment of the first telescopic part can be realized by making the first telescopic part and the vertical rod rotate relative to each other through external force. The above locking nut is used to realize the connection between the threaded rod and the vertical rod after adjustment locking. For ease of manufacture, it is preferably set such that the axis of the internally threaded hole on the pole is collinear with the axis of the pole.

In summary, when the support structure is installed, it is equivalent to the combination rod being clamped between adjacent floors, that is, when the support structure is installed, it is a necessary step to adjust the length of the combination rod. For the installation efficiency of the support structure, among the threaded rods at both ends of each vertical rod, the thread on one of the threaded rods is a coarse thread, and the thread on the other threaded rod is a fine thread. In this solution, the above coarse thread is used to realize the rapid and coarse adjustment of the length of the combined rod, and the above fine thread is used to realize the fine adjustment of the length of the combined rod, that is, after the length of the combined rod has been coarsely adjusted to a certain extent, the fine thread can then be used .

The above combined rod can realize the position constraint of the support frame in the height direction in the space. In order to make the support frame also have good position accuracy in the horizontal direction in the space, it also includes a cross bar connected to the support frame. Both ends of the crossbar are provided with second telescopic parts, and two second pads are also included; the second pads are all wooden blocks. The combined rod formed by the above second telescopic part and the cross bar is used to interact with the walls on the left and right sides of the support frame, that is, through the walls on both sides, to avoid the left and right movement of the support frame when subjected to a large impact force. The function of the above second cushion block is the same as that of the first cushion block, and is used to increase the contact area between the support frame and the building. In this solution, it is preferable to set the combined rods composed of the cross bar and the second telescopic part to be multiple, and the combined rods composed of the cross bar and the second telescopic part are installed crosswise on the main body of the support frame to ensure any The total length of the composite rod composed of the cross bar and the second telescopic part is greater than the distance between the walls on both sides of the support frame, that is, the length direction of the composite rod composed of the cross rod and the second telescopic part does not fall within the distance between the corresponding walls on both sides In this way, it can effectively ensure that the support frame will rotate when it is subjected to excessive impact force. By setting the above second block as a wooden block, the characteristics of the soft and rough surface of the wooden block itself can be used to increase the friction between the support frame and the building, so that the support frame is subjected to the force brought by the falling object. When the impact force occurs, its position in the building will not be affected by the above impact force; at the same time, in the process of extending the second telescopic part, the characteristics of easy deformation of the wooden block can be used, so that the building will not be damaged due to excessive force. Large surfaces are damaged.

The second telescopic part is a threaded rod on which a locking nut is threaded, and among the two second telescopic parts, the thread on one of the threaded rods is a coarse thread, and the thread on the other threaded rod is Fine thread. In this solution, the above coarse thread is used to realize rapid and coarse adjustment of the length of the combined rod, and the above fine thread is used to realize the fine adjustment of the length of the corresponding combined rod, that is, after the length of the combined rod has been coarsely adjusted to a certain extent, the fine thread thread.

In order to make the above protective net not limited to the use of mesh structure to block large falling objects, when it is used to block welding spatter and rainwater, in order to enable welding spatter and rainwater to collect in a specific area of the protective net, limit the welding Splashes and rainwater can fall from a specific edge position of the protective net, which is set as follows: the lower end of the support rod is hingedly connected with the support frame through a hinge shaft, and also includes a winch and a pull rope wound on the winch, and the winch is fixed on the support On the frame, the free end of the stay rope is connected with the upper end of the strut. In this scheme, the inclination of the struts can be adjusted through the winch, so that when multiple supporting structures support the protective net, the inclination of the struts on a single support structure can be adjusted at any time to adjust the state of the protective net. Purpose.
