Description

Technical Field

[0001] The utility model application belongs to the technical field of external scaffolding protection nets, and specifically relates to a connection structure between a steel plate net and an external scaffolding. Background Art

[0002] In the construction of high-rise buildings, in order to prevent workers from falling and ensure the safety of construction workers, external scaffolding protection nets will be laid on the external scaffolding. The external scaffolding protection net is usually made of several steel plate nets laid on the outside of the external scaffolding. In addition to effectively protecting the lives of construction workers, it can also provide wind and rain protection for equipment and materials on the construction site to reduce environmental pollution. At the same time, in order to ensure the construction period, the external scaffolding protection net is also required to be easy to install and disassemble, and can be quickly erected and dismantled after completion.

[0003] In the specific construction process, the use of external scaffolding protection nets often has the following problems:

[0004] When using some components such as wire ropes and wall-penetrating steel pipes, they need to be passed from the main body of the building through the external scaffolding protective net to the external environment. Since the protective net is usually a closely arranged steel plate mesh, it forms an obstruction to it. At this time, the steel plate mesh that has an obstructive effect must be moved or removed to form sufficient avoidance gaps for wire ropes, wall-penetrating steel pipes and other components to pass through and be used.

[0005] However, the existing connection method between the external scaffolding and the steel mesh has limitations - after the steel mesh is installed and fixed to the external scaffolding, it is often impossible to make local adjustments. When there is a conflict with the use of steel wire ropes, wall-penetrating steel pipes, etc., the conflicting steel mesh can only be removed as a whole, resulting in a large gap left at this position, which not only affects the overall appearance of the external scaffolding protective net, but also directly affects the use effect of the external scaffolding protective net.

[0006] Therefore, it is urgent to design a new connection device or method between the steel plate mesh and the external scaffolding, which can make the connection between the two more flexible, so that each steel plate mesh can be moved locally, overcoming the defect that the steel plate mesh can no longer be locally moved after installation, thereby avoiding the problem of overall dismantling of the steel plate mesh and the formation of excessive avoidance gap after dismantling, so as to achieve the purpose of making the external scaffolding protective net better play a protective and wind and rainproof role. Utility Model Content

[0007] The utility model application discloses a connection structure of a steel plate mesh and an external scaffolding to solve the problems existing in the above-mentioned prior art.

[0008] To achieve the above-mentioned purpose, the utility model provides a connection structure between a steel plate mesh and an external scaffolding, comprising: the steel plate mesh is movably installed on the outside of the vertical pole of the external scaffolding through a movable connection mechanism; when it is necessary to adjust the installation height of the steel plate mesh, the movable connection mechanism is opened and drives the steel plate mesh to extend outward, and then the height is adjusted upward or downward.

[0009] Furthermore, the movable connection mechanism includes: a connecting part, used to connect with the vertical pole; a mounting part, used to connect with the steel plate mesh; a folding part, one or more groups of folding structures, one end of the folding part is hinged to the connecting part, and the other end is hinged to the mounting part.

[0010] Furthermore, the folding part includes a first folding strip and a second folding strip, and the first folding strip is provided with an open groove for accommodating the second folding strip; the open end of the first folding strip is hinged to one end of the second folding strip, and the other end of the first folding strip is hinged to the connecting part; the other end of the second folding strip is hinged to the mounting part.

[0011] Furthermore, the connecting portion is a strip-shaped structure, and the width of the upper end portion is greater than that of the lower end portion.

[0012] Furthermore, a plurality of slots for accommodating the connecting parts are evenly spaced on the side wall of the vertical pole.

[0013] Furthermore, the slot is a through slot.

[0014] Furthermore, the mounting portion is an I-shaped structure, and the steel plate mesh is inserted between its two flange plates. Each flange plate is provided with a mounting hole for connecting the steel plate mesh; and a through hole matching the mounting hole is provided at a corresponding position of each steel plate mesh frame.

[0015] The advantages and positive effects of the utility model are:

[0016] 1. The connection structure between the steel plate mesh and the external scaffolding disclosed in the utility model application is that the steel plate mesh is installed on the outside of the vertical pole through a movable connection mechanism. The movable connection mechanism makes the connection between the steel plate mesh and the vertical pole more flexible, and the steel plate mesh can be moved up and down locally through the movable connection mechanism. When it is necessary to adjust the height of the steel plate mesh, the movable connection mechanism can be used to first extend the steel plate mesh to the outside of the vertical pole, and then the height of the steel plate mesh can be adjusted. This technical solution overcomes the defect that the steel plate mesh cannot be moved locally after being installed on the vertical pole in actual construction, and solves the problem that when construction components such as wire ropes and wall-penetrating steel pipes need to pass through the external scaffolding protective net from the main body of the building, the existing construction method needs to remove part of the steel plate mesh as a whole to form an avoidance gap, and the existing construction method causes the avoidance gap to be too large, which affects the use effect of the external scaffolding protective net. This connection structure allows the steel plate mesh to only be fine-tuned locally at the original position, and the size of the avoidance gap formed is more reasonable, achieving the technical effect of ensuring that construction components can pass through without affecting the use of the external scaffolding protection net. Ultimately, the purpose of enabling the external scaffolding protection net to better protect and shelter from wind and rain is achieved, and this solution has a simple structure and is easy to operate.

[0017] 2. The connection structure of the steel plate mesh and the external scaffolding disclosed in the utility model application is designed as a folding and telescopic structure. When the installation position of the relevant steel plate mesh needs to be adjusted on the construction site, it is only necessary to use the movable connection mechanism to stretch and move the steel plate mesh outward, and then adjust the steel plate mesh to a suitable position, so as to form a sufficient gap for steel wire ropes, wall-penetrating steel pipes and other components to pass through; and when the construction site does not need to use the adjustment of the position of the steel plate mesh, it is only necessary to fold and shrink the movable connection mechanism, and install the steel plate mesh and the vertical pole normally, so as to save space;

[0018] 3. The connection structure of the steel plate mesh and the external scaffolding disclosed in the utility model application is hinged by bolts between the connection part, the first folding strip, the second folding strip and the installation part, and is fastened and fixed by installing nuts on the bolts. This design increases the flexibility of the connection structure and is detachable. Construction workers can arbitrarily adjust the extension degree of the folding part and the angle of the steel plate mesh according to the size of the avoidance gap required on site, and the connection is firm.

[0019] 4. The connection structure between the steel plate mesh and the external scaffolding disclosed in the utility model application has a strip-shaped connection portion which is inserted into a slot on the side wall of the vertical pole, and the slot is a through slot. This design makes the implementation of the solution more convenient and saves materials.

[0020] 5.

[0031] The specific implementation of the utility model application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0032] In the technical solution disclosed in the utility model application, "inside" and "outside" refer to the inside and outside relative to the outline of the component or structure itself. In addition, it should be noted that the terms used, such as "first" and "second", are used to distinguish one element from another element and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0033] According to the utility model application, a connection structure between a steel plate mesh and an external scaffolding is disclosed, such as Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the steel plate mesh 2 is movably installed on the outside of the vertical pole 1 of the external scaffolding through a movable connection mechanism 3;

[0034] When the installation height of the steel plate mesh 2 needs to be adjusted, the movable connection mechanism 3 is opened and drives the steel plate mesh 2 to extend outward, and then the height is adjusted upward or downward.

[0035] In the above technical solution, the steel plate mesh 2 is installed on the outside of the vertical pole 1 through the movable connection mechanism 3. The movable connection mechanism 3 makes the connection between the steel plate mesh 2 and the vertical pole 1 more flexible, and the steel plate mesh 2 can be moved up and down locally through the movable connection mechanism 3. Figure 6 , Figure 7 and Figure 8 As shown, when the installation height of the steel plate mesh 2 needs to be adjusted, the steel plate mesh 2 is first extended to the outside of the vertical pole 1 using the movable connection mechanism 3, and then the height of the steel plate mesh 2 is adjusted.

[0036] This design overcomes the defect that the steel plate mesh 2 cannot be moved locally after being installed on the vertical pole 1 in actual construction, thereby solving the problem that when some construction components such as steel wire ropes and wall-penetrating steel pipes need to pass through the external scaffolding protection net from the main body of the building, the existing construction method requires the overall removal of part of the steel plate mesh 2 to form an avoidance gap, and the problem that the avoidance gap formed by the existing construction method is too large, which affects the use effect of the external scaffolding protection net. This connection structure can make the steel plate mesh 2 unnecessary to be removed, and only needs to be fine-tuned locally at the original position to make the size of the avoidance gap formed more reasonable, achieving the technical effect of ensuring that the construction components pass through without affecting the use of the external scaffolding protection net. This design is an upgrade and optimization of the original structure, and ultimately achieves the purpose of enabling the external scaffolding protection net to better protect and shelter from wind and rain.

[0041] In the above technical solution, the folding part 302 is a retractable folding structure. This design can better achieve the purpose of extending the steel plate mesh 2 to the outside of the vertical pole 1 and then adjusting the height of the steel plate mesh 2. "One end of the folding part 302 is hinged to the connecting part 301, and the other end is hinged to the mounting part 303", specifically, the folding part 302 is flexibly hinged with the connecting part 301 and the mounting part 303 by using bolts and nuts. When the steel plate mesh 2 is adjusted to the desired position, the steel plate mesh 2 can be fixed to the desired position by tightening the bolts and nuts. When the position of the relevant steel plate mesh 2 needs to be adjusted at the construction site, it is only necessary to use the movable connection mechanism 3 to stretch and move the steel plate mesh 2 to the outside, and then adjust the steel plate mesh 2 to a suitable position, so that sufficient gaps can be formed for components such as wire ropes and wall-penetrating steel pipes to pass through; and when the construction site does not need to use the adjustment of the position of the steel plate mesh 2, it is only necessary to fold and shrink the movable connection mechanism 3, and install the steel plate mesh 2 and the vertical pole 1 normally to save space.

[0042] In some specific embodiments, such as Figure 4 , Figure 5 As shown, the folding portion 302 includes a first folding strip 302a and a second folding strip 302b, and the first folding strip 302a is provided with an opening groove for accommodating the second folding strip 302b;

[0043] The open end of the first folding strip 302a is hinged to one end of the second folding strip 302b, and the other end of the first folding strip 302a is hinged to the connecting portion 301;

[0044] The other end of the second folding strip 302 b is hinged to the mounting portion 303 .

[0045] In the above technical solution, the folding portion 302 includes at least one group of folding components, namely, a first folding strip 302a and a second folding strip 302b. In practice, the folding components can be appropriately increased according to the construction site and the size of the installed steel plate mesh 2, and a plurality of first folding strips 302a and second folding strips 302b can be installed to meet the requirements of the construction site.

[0046] In other embodiments, Figure 3 , Figure 4 , Figure 5 As shown, the connection part 301 is a strip structure, the width of the upper end thereof is greater than the lower end (not clearly shown in the drawings of the specification), and a plurality of slots 101 for inserting the connection part 301 are evenly spaced on the side wall of the upright pole 1. Furthermore, for greater convenience and material saving, the slots 101 can be designed as through slots.

[0047] In some other embodiments, such as Figure 4 , Figure 5As shown, the mounting portion 303 is an I-shaped structure, and the steel plate mesh 2 is inserted between its two flange plates, and each flange plate is provided with a mounting hole 303a for connecting the steel plate mesh 2;

[0048] And a through hole matching the mounting hole 303a is formed at a corresponding position of the frame of each steel plate mesh 2 (not shown in the drawings of the specification).

[0049] The utility model application exemplarily describes the use method of the connection structure of the steel plate mesh and the external scaffolding in the external scaffolding protection net, which is as follows:

[0050] S1. Each steel plate mesh 2 is sequentially installed on the vertical pole 1 through the movable connection mechanism 3. The connection part 301 on each movable connection mechanism 3 is inserted into the slot 101. The frames on both sides of each steel plate mesh 2 are bolted to the installation part 303, that is, one steel plate mesh 2 is height-adjusted by two movable connection mechanisms 3, and the outer edges of two adjacent steel plate meshes 2 are closely arranged to form an integral protective net on the external scaffolding;

[0051] S2. According to the position where the component to be used passes through the outer scaffolding protection net, adjust part of the steel plate mesh 2 on the outer scaffolding protection net: loosen the nuts on the hinged bolts between the connecting part 301, the first folding strip 302a, the second folding strip 302b and the mounting part 303, first extend the steel plate mesh 2 outward, and then adjust the height position of the steel plate mesh 2;

[0052] S3. Adjust the steel plate mesh 2 to the desired position, and then tighten the nuts on the hinge bolts between the connecting part 301, the first folding strip 302a, the second folding strip 302b and the mounting part 303 to fix them at this position.
