[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Traditional dry-hanging stone wall construction requires the use of expansion bolts to fix the embedded plate, and then welding the vertical steel frame to the embedded plate. However, in modern buildings, lightweight partition walls are often used in this area, such as autoclaved aerated concrete blocks, hollow bricks, interlocking blocks, and ALC concrete lightweight partition panels. These materials do not meet the requirements for using expansion bolts. Instead, the steel frame needs to be fixed from top to bottom or fixed to the concrete structural column or ring beam, or through bolts can be used to fix it to the embedded plate. This method is less efficient, more labor-intensive, and more costly.

[0024] The wall frame installation structure 1 disclosed in this application does not require the use of expansion bolts to fix the embedded plate, nor does it require the steel frame to be fixed to the top and bottom or to the concrete structural column or ring beam. As a result, the construction difficulty is reduced, the construction efficiency is improved, and the construction cost is reduced.

[0025] Reference Figures 1 to 4 The present invention discloses a wall frame installation structure 1, which includes multiple vertical mounting rods 10 and multiple fixing units 20. Each vertical mounting rod 10 is fixed to the decorative surface of the building wall 2 by multiple mounting components. The multiple vertical mounting rods 10 are spaced apart along the first direction 40 of the building wall 2, and the multiple vertical mounting rods 10 extend along the second direction 50 of the building wall 2.

[0026] The wall frame installation structure 1 provided in this embodiment can be used in elevator lobbies with dry-hanging stone wall cladding, and can also be used in the lobby of public buildings with dry-hanging stone wall cladding. This embodiment does not limit it in this regard.

[0027] For ease of explanation, the following description uses the wall frame installation structure 1 for an elevator lobby with dry-hanging stone wall cladding as an example.

[0028] The vertical mounting rod 10 is made of channel steel or galvanized square steel.

[0029] It should be noted that the first direction 40 of the building wall 2 is the length direction of the building wall 2, the second direction 50 of the building wall 2 is the height direction of the building wall 2, and the third direction 60 of the building wall 2 is the width direction of the building wall 2. The first direction 40, the second direction 50 and the third direction 60 of the building wall 2 are set perpendicular to each other.

[0030] Specifically, each vertical mounting rod 10 is fixed to the decorative surface of the building wall 2 by multiple mounting components, which are spaced apart along the second direction 50.

[0031] Among them, such as Figure 1 As shown, each vertical mounting rod 10 is fixed to the decorative surface of the building wall 2 by three spaced-apart mounting components.

[0032] In this embodiment, each installation component includes two installation units 30, which are respectively disposed on opposite sides of the vertical installation rod 10. The self-locking end of the installation unit 30 passes through the building wall 2 and is locked and fixed to the back of the building wall 2. The other end of the installation unit 30 is located outside the building wall 2 and is connected to the outer wall of the vertical installation rod 10. Multiple fixing units 20 are fixed to the decorative surface of the building wall 2 by the vertical installation rod 10. The multiple fixing units 20 are spaced apart along the second direction 50, and each fixing unit 20 extends along the first direction 40. The dry-hanging stone is used for dry-hanging installation on the fixing unit 20. By using the installation unit 30 to fix the vertical installation rod 10 to the decorative surface of the building wall 2, compared with the traditional dry-hanging stone construction, the construction efficiency is improved and the construction period is shortened. At the same time, the construction cost is reduced.

[0033] The construction process of the wall frame installation structure 1 provided in this embodiment is as follows: multiple through holes are drilled on the building walls 2 on both sides of the elevator door opening. The multiple through holes penetrate the building walls 2 along the third direction 60. The self-locking end of the installation unit 30 passes through the through hole and is locked and fixed to the back of the building wall 2. The other end of the installation unit 30 is located outside the building wall 2 and is connected to the outer wall of the vertical installation rod 10. After the vertical installation rod 10 is installed, the fixing unit 20 is fixed to the decorative surface of the building wall 2 through the vertical installation rod 10. The stone 4 is dry-hung on the fixing unit 20 through the stainless steel stone dry-hanging parts 3.

[0034] It should be noted that the stainless steel stone dry-hanging component 3 is a component well known to those skilled in the art, and its structure will not be described in detail here.

[0035] Furthermore, in this embodiment, the installation unit 30 includes a heavy-duty orchid clip 31 and a corner bracket 32. The first sidewall of the corner bracket 32 ​​is attached to the decorative surface of the building wall 2, and the second sidewall of the corner bracket 32 ​​is attached to the outer sidewall of the vertical mounting rod 10. The self-locking end of the heavy-duty orchid clip 31 passes through the first sidewall of the corner bracket 32 ​​and the building wall 2, and is locked and fixed to the back of the building wall 2. The other end of the heavy-duty orchid clip 31 passes through the second sidewall of the corner bracket 32 ​​and is threadedly connected to a nut. By setting the heavy-duty orchid clip 31, compared with the traditional dry-hanging stone construction, the construction efficiency is improved, the construction period is shortened, and the construction cost is reduced. At the same time, when the back of the building wall 2 is an elevator shaft or a closed space, the use of the heavy-duty orchid clip 31 reduces the construction difficulty and construction cost.

[0036] Specifically, an installation hole is provided on the first side wall of the corner bracket 32. The installation hole penetrates the first side wall of the corner bracket 32. The center line of the installation hole is connected to the through hole on the building wall 2. The center line of the installation hole and the center line of the through hole are both set parallel to the third direction 60.

[0037] The second side wall of the corner bracket 32 ​​and the outer side wall of the vertical mounting rod 10 can be connected by welding. Alternatively, the second side wall of the corner bracket 32 ​​and the outer side wall of the vertical mounting rod 10 can be connected by bolts.

[0038] During installation, the self-locking end of the heavy-duty orchid clip 31 passes through the mounting hole and the through hole in sequence and is locked and fixed to the back of the building wall 2. The other end of the heavy-duty orchid clip 31 is located on the side of the corner bracket 32 ​​away from the building wall 2 and is threadedly connected to the nut so that the corner bracket 32 ​​is fixed to the building wall 2 by the heavy-duty orchid clip 31.

[0039] Continue to refer to Figure 5 and Figure 6 In this embodiment, the heavy-duty orchid clip 31 includes a screw 311 and a self-closing hinge 312. The self-closing hinge 312 is connected to one end of the screw 311 via a rotating shaft 313, and the self-closing hinge 312 can rotate relative to the screw 311. When the self-closing hinge 312 is in the initial state, it covers the end of the screw 311, and its extension direction is parallel to the center line of the screw 311. When the self-closing hinge 312 is in the locked state, it is sleeved on the end of the screw 311, and its extension direction is perpendicular to the center line of the screw 311. By setting the self-closing hinge 312, compared with the traditional dry-hanging stone construction, it is not necessary to pre-embed steel plates on the back of the building wall 2. The self-closing hinge 312 of the heavy-duty orchid clip 31 self-locks to achieve fastening with the corner bracket 32 ​​on the front (i.e., the decorative surface) of the building wall 2.

[0040] Specifically, during use, the centerline of the screw 311 is set parallel to the third direction 60, and the centerline of the rotating shaft 313 is set perpendicular to the centerline of the screw 311.

[0041] During installation, the self-closing hinge 312 is fitted over the end of the screw 311, with the extension direction of the self-closing hinge 312 parallel to the centerline of the screw 311. The end of the screw 311 covered with the self-closing hinge 312 is then passed through the mounting hole and the through hole in sequence. When the self-closing hinge 312 has completely passed through the through hole, it rotates downward under its own weight. At this point, the self-closing hinge 312 is fitted over the end of the screw 311, with the extension direction of the self-closing hinge 312 perpendicular to the centerline of the screw 311. In other words, the self-closing hinge 312 fixes the screw 311 inside the building wall 2, preventing the screw 311 from passing through the through hole. The end of the screw 311 away from the self-closing hinge 312 is threadedly connected to a nut, and one end of the nut abuts against the first side wall of the angle bracket 32, so that the angle bracket 32 ​​is locked onto the decorative surface of the building wall 2.

[0042] Furthermore, in this embodiment, the self-clinching hinge 312 includes an arc plate 3121 and two oppositely arranged plates 3122. The two plates 3122 are respectively disposed on opposite sides of the opening of the arc plate 3121. The arc plate 3121 and the two plates 3122 together form an accommodating cavity. A through-hole 3123 is provided on the arc plate 3121, which communicates with the accommodating cavity. The rotating shaft 313 passes through the end of the screw 311, and the two protruding ends of the rotating shaft 313 are respectively inserted into... The screw 311 is installed in two plates 3122, which can rotate relative to the rotating shaft 313. When the self-clamping joint 312 is in the initial state, the end of the screw 311 is inserted into the accommodating cavity, and the center line of the screw 311 is parallel to the center line of the arc plate 3121. When the self-clamping joint 312 is in the locked state, the end of the screw 311 extends through the through-hole 3123 to the outside of the self-clamping joint 312, and the center line of the screw 311 is perpendicular to the center line of the arc plate 3121.

[0043] Furthermore, in this embodiment, the heavy-duty orchid clip 31 also includes a washer 314, which is attached to the side of the corner bracket 32 ​​away from the building wall 2. The screw 311, away from the end of the self-dangling hinge 312, passes through the first side wall of the corner bracket 32 ​​and is threadedly connected to the washer 314 and the nut.

[0044] During installation, the gasket 314 and the first side wall of the corner bracket 32 ​​are attached to the side away from the building wall 2. The screw 311, away from the end of the self-dangling hinge 312, passes through the mounting hole and the hole on the gasket 314 in sequence and is threadedly connected to the nut. One end of the nut abuts against the gasket 314.

[0045] Continue to refer to Figures 1 to 4In this embodiment, each fixing unit 20 includes multiple horizontal mounting rods 21, and a horizontal mounting rod 21 is installed between every two adjacent vertical mounting rods 10. The multiple horizontal mounting rods 21 together form a straight line.

[0046] Specifically, the two ends of the horizontal mounting rod 21 are connected to the side walls of two adjacent vertical mounting rods 10, respectively. The extension direction of the horizontal mounting rod 21 is parallel to the first direction 40.

[0047] The horizontal mounting rod 21 and the vertical mounting rod 10 can be connected by welding. Alternatively, they can be connected by bolts.

[0048] In this embodiment, the horizontal mounting rod 21 is made of galvanized angle steel.

[0049] The construction process of the wall frame installation structure 1 provided in this embodiment is as follows: Angle brackets 32 are welded to opposite sides of the vertical mounting rod 10, and mounting holes are made on the angle brackets 32. Then, through holes are drilled in the building wall 2, extending along a third direction 60 through the building wall 2, ensuring that the mounting holes correspond one-to-one with the through holes. A self-closing hinge 312 is fitted over the end of the screw rod 311, i.e., the extension direction of the self-closing hinge 312 is parallel to the centerline direction of the screw rod 311. The end of the screw rod 311 covered with the self-closing hinge 312 is passed sequentially through the holes, mounting holes, and through holes on the gasket 314. When the self-closing hinge 312 completely passes through the through hole, the self-closing hinge 312 rotates downwards under its own weight. At this time, the self-closing hinge 312 is fitted onto the... The end of the screw 311, i.e., the extension direction of the self-adhesive hinge 312, is perpendicular to the centerline of the screw 311. That is to say, the self-adhesive hinge 312 fixes the screw 311 inside the building wall 2, preventing the screw 311 from passing through the through hole. The end of the screw 311 away from the self-adhesive hinge 312 is threadedly connected to the nut, and one end of the nut abuts against the washer 314, so that the corner bracket 32 ​​is locked on the decorative surface of the building wall 2. After all the corner brackets 32 are fixed, the vertical mounting rod 10 is fixed on the decorative surface of the building wall 2. Then, the horizontal mounting rod 21 is installed between two adjacent vertical mounting rods 10 to assemble a steel frame installation structure. The stone 4 is dry-hung on the fixing unit 20 through the stainless steel stone dry-hanging parts 3.

[0050] The wall frame installation structure 1 provided in this application includes multiple vertical mounting rods 10 and multiple fixing units 20. Each vertical mounting rod 10 is fixed to the decorative surface of the building wall 2 by multiple mounting components. The multiple vertical mounting rods 10 are spaced apart along a first direction 40 of the building wall 2, and each of the multiple vertical mounting rods 10 extends along a second direction 50 of the building wall 2. Each mounting component includes two mounting units 30, which are respectively located on opposite sides of the vertical mounting rod 10. The self-locking end of the mounting unit 30 passes through the building wall 2 and is locked and fixed to the back of the building wall 2. The other end of the mounting unit 30 is located outside the building wall 2 and is connected to the outer wall of the vertical mounting rod 10. The multiple fixing units 20 are fixed to the decorative surface of the building wall 2 by the vertical mounting rods 10. The multiple fixing units 20 are spaced apart along the second direction 50, and each fixing unit 20 extends along the first direction 40. By setting the mounting units 30, compared with the traditional dry-hanging stone construction, the construction efficiency is improved, the construction period is shortened, and the construction cost is reduced.

[0051] The wall frame installation structure 1 provided by this utility model has the following advantages: the device has a simple structure, is easy to manufacture, and is easy to operate.
