[0034] The lower connecting unit includes a connecting seat 304, an arc-shaped side panel 305, and a vertical connecting arm 306; the connecting seat 304 is provided with two groups, and the two groups of connecting seats 304 are symmetrically fixed at the bottom of both ends of the arc-shaped bottom plate 301, and the arc-shaped side panels 305 are rotatably connected to the connecting seat 304 through a rotating shaft and are sleeved on the outer side of the building's external steel frame 4 through the two arc-shaped side panels 305 to realize the connection between the arc-shaped bottom plate 301 and the support tube 201; the vertical connecting arm 306 is fixed to the end surfaces of the two arc-shaped side panels 305 that are away from each other and extends through the linear slide groove 205 to the top of the support tube 201, and is used to realize the mutual embrace of the two arc-shaped side panels 305 by gathering the two vertical connecting arms 306, thereby realizing convenient sleeve connection with the building's external steel frame 4.

[0035] The pre-fixed locking member 308 includes a hammer block 3081, a second wedge-shaped block 3082, an extrusion block 3083, and a limit slider 3084; the second wedge-shaped block 3082 and the limit slider 3084 are fixed to the bottom of the hammer block 3081, there are two limit sliders 3084 and they are symmetrically fixed on both sides of the second wedge-shaped block 3082, there are two extrusion blocks 3083 and they are symmetrically fixed to the bottom of both ends of the second wedge-shaped block 3082; the vertical connecting arm 3081 is provided with a plurality of screws 3083, and the screws 3083 are ... 06 is provided with a vertical slide groove 307, a positioning groove 303 is provided on the side of the L-shaped hook arm 302 near the top bend, and positioning tooth blocks 206 are provided on both sides of the inner wall of the linear slide groove 205; the second wedge-shaped block 3082 is distributed in the space enclosed by the two L-shaped hook arms 302 and the two vertical connecting arms 306, and the extrusion block 3083 is limitedly slidably connected in the vertical slide groove 307 to guide the up and down movement of the second wedge-shaped block 3082.

[0036] By hammering the hammer block 3081, the pre-fixed locking piece 308 is moved downward as a whole, so that the second wedge-shaped block 3082 can squeeze the two arc-shaped side panels 305 and the limiting slider 3084 can squeeze the two L-shaped hook arms 302, thereby achieving the two arc-shaped side panels 305 to fit tightly against the outer side of the building's external steel frame 4 and the positioning slot 303 to be clamped in the positioning tooth block 206.

[0037] In this embodiment, the specific steps for installing the expanded metal mesh 1 are as follows:

[0038] First, take out a connector consisting of a set of support components 2 and connection components 3, and then manually press the bottom of the two vertical connecting arms 306 to make their tops close to each other (it should be noted that: at this time, the pre-fixed locking piece 308 does not squeeze the vertical connecting arm 306 and the L-shaped hook arm 302, that is, at this time, the pre-fixed locking piece 308 and the vertical connecting arm 306 are both movable relative to each other), and the vertical connecting arm 306 can drive the arc-shaped side panel 305 to rotate outward with the connecting seat 304 as the base, and the two arc-shaped side panels 305 are separated from each other. At this time, the two arc-shaped side panels 305 can be embraced on the outside of the building's external steel frame 4, and then release the pressure on the vertical connecting arm 306. The arc-shaped side panel 305 will be reset and fit to the outside of the building's external steel frame 4 under the action of its own gravity, thereby realizing the initial connection between the connector and the building's external steel frame 4.

[0039] Then, the position of the support pipe 201 is adjusted according to the installation position of the steel plate mesh 1, so as to ensure that the support pipe 201 can effectively support the steel plate mesh 1, and at the same time make the distance between the steel plate mesh 1 and the external steel frame 4 of the building meet the set distance, and the operation is as follows:

[0040] Since the arc-shaped side panel 305 and the external steel frame 4 of the building are not fixed at this time, the entire connecting piece can be moved horizontally along the outer wall of the external steel frame 4 of the building, so that the support tube 201 can be adjusted to be directly below the installation position of the steel plate mesh 1. In addition, since the arc-shaped bottom plate 301 and the support tube 201 are in a sliding connection state through the cooperation of the L-shaped hook arm 302 and the straight slide groove 205, the support tube 201 can be moved horizontally and longitudinally with the arc-shaped bottom plate 301 as the base, thereby realizing the distance adjustment between the L-shaped hook 202 and the external steel frame 4 of the building, and the position of the L-shaped hook 202 is the installation position of the steel plate mesh 1.

[0041] When the position adjustment of the support tube 201 is completed, the hammer block 3081 can be knocked downward by an external tool to move the pre-fixed lock 308 downward as a whole, wherein the second wedge-shaped block 3082 will squeeze the two vertical connecting arms 306, and this squeezing force is transmitted to the two arc-shaped side panels 305 so that the arc-shaped side edges 305 can fit tightly against the surface of the building's external steel frame 4, thereby achieving pre-fixation of the arc-shaped side panels 305 and the building's external steel frame 4. At the same time, the limiting slider 3084 can squeeze the two L-shaped hook arms 302, causing the L-shaped hook arms 302 to undergo micro-deformation, and the positioning slot 303 on the L-shaped hook arm 302 is engaged with the positioning tooth block 206 on the side of the linear slide groove 205, thereby achieving the relative position fixation of the support tube 201 and the arc-shaped bottom plate 301.

[0042] After that, other connectors are installed according to the above operation (it should be noted that the number of connectors required to be installed under a single steel mesh 1 shall not be less than two). After the corresponding number of connectors are installed, the bottom edge of the steel mesh 1 can be clamped to the L-shaped hook 202, and then the first wedge-shaped clamping block 204 is hammered with a tool to move it down along the T-shaped plug-in slot 203. At this time, the first wedge-shaped clamping block 204 is closely fitted with the end face of the steel mesh 1, thereby fixing the steel mesh 1. After that, the corresponding number of connectors are installed on the top of the steel mesh 1, and the operation steps are the same as above.

[0043] The steel mesh 1 can be quickly installed by cooperating with the above multiple parts. Compared with the traditional structure of combined installation of scattered parts, the support component 2 and the connecting component 3 are combined into an integral structure, which is not only easier to operate, but also requires fewer actions to tighten the bolts during the overall installation. Only two wedge-shaped blocks are needed to complete the initial installation, and finally one bolt is used for reinforcement, and the overall installation efficiency is faster.

[0044] Please refer to Figures 7 and 8The reinforcement unit includes a lower extension block 309 and a through hole 310; the lower extension block 309 is integrally formed at the bottom of the arc-shaped side plate 305, and the through hole 310 is opened on the end face of the lower extension block 309. Bolts penetrate the through holes 310 on the two lower extension blocks 309 and are tightened with nuts to achieve the connection and reinforcement between the arc-shaped side plate 305 and the external steel frame 4 of the building.

[0045] In this embodiment: after completing the installation of a single steel plate mesh 1, you can check whether the position of the connecting piece is appropriate. If adjustment is required, you only need to knock the bottom of the hammer block 3081 upwards through the workpiece to move the pre-fixed lock 308 upward as a whole, thereby releasing the squeezing of the vertical connecting arm 306 and the L-shaped hook arm 302. The L-shaped hook arm 302 automatically resets to release the clamping connection with the positioning tooth block 206. At this time, the position of the support pipe 201 can be fine-tuned again. This operation facilitates the accurate installation of the steel plate mesh 1. After determining the position of the support pipe 201, knock the hammer block 3081 downwards again, and then pass the bolts through the through holes 310 on the two lower extension blocks 309 and tighten them with the nuts to reinforce the fastening state of the arc side plate 305 and the external steel frame 4 of the building, thereby ensuring the stable installation of the steel plate mesh 1.

[0046] Please refer to Figure 5 The top length of the first wedge-shaped block 204 is greater than the length of the T-shaped plug-in slot 203, the bottom length of the first wedge-shaped block 204 is less than the diameter of the inscribed circle of the square slot at the end of the T-shaped plug-in slot 203, and an anti-drop block is integrally formed at the bottom of the first wedge-shaped block 204. The width of the first wedge-shaped block 204 matches the width of the inner wall of the straight slot of the T-shaped plug-in slot 203.

[0047] In this embodiment, this structure can prevent the first wedge-shaped block 204 from falling off. It should also be noted that the square notch at the end of the T-shaped plug-in slot 203 is used to provide a rotation space for the first wedge-shaped block 204 .

[0048] By rotating the first wedge-shaped block 204 to a state perpendicular to the straight slot of the T-shaped slot 203 and tilting it away from the L-shaped hook 202, the first wedge-shaped block 204 can avoid the installation area of ​​the steel plate mesh 1 without affecting the docking of the steel plate mesh 1 and the L-shaped hook 202. Then, the first wedge-shaped block 204 can be rotated to a state parallel to the straight slot of the T-shaped slot 203.

[0049] Please refer to Figures 1 to 8The support tube 201, L-shaped hook 202, T-shaped slot 203, linear slide 205, and positioning tooth block 206 are integrally formed from a round tube by stamping, punching, and bending processes; the arc bottom plate 301, L-shaped hook arm 302, and positioning slot 303 are integrally formed from a steel plate by punching, stamping, and bending processes; the arc side plate 305, lower extension block 309, and through hole 310 are integrally formed from a steel plate by punching and stamping processes.

[0050] In this embodiment: the above structure makes the overall production and assembly process of the assembly component 2 and the connection component 3 simple, without complex structure, and easy to put into production and application.

[0051] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
