Description

Technical Field

[0001] This invention relates to the field of curtain wall fixing structure technology, specifically to a rapid pre-fixing structure for curtain wall installation of building devices. Background Technology

[0002] A curtain wall is a non-load-bearing exterior wall cladding for a building. It hangs like a curtain, hence the name "curtain wall." It is a lightweight wall structure commonly used in modern large and high-rise buildings for decorative purposes. Composed of panels and a supporting structural system, it is a building envelope or decorative structure that can have a certain degree of displacement relative to the main structure or its own deformation capacity, and does not bear the load of the main structure.

[0003] While existing pre-fixed structures simplify the installation process to some extent, several insurmountable problems remain. First, the positioning accuracy of embedded parts is a key factor affecting the quality of curtain wall installation. However, due to limitations in construction conditions and errors in measurement technology, the positioning accuracy of embedded parts is often difficult to guarantee, leading to misalignment during installation. Second, the connection method between embedded parts and the keel is also a crucial factor affecting the stability and safety of the curtain wall. However, existing connection methods between embedded parts and the keel are relatively simple, mainly using welding or bolts. These methods not only have limited connection strength but are also susceptible to corrosion, failing to meet the needs of different curtain wall types and complex building structures. Therefore, we propose a rapid pre-fixed structure for curtain wall installation. Summary of the Invention

[0006] A sleeve is movably connected at the center of the axial direction of the positioning post, and a threaded cylinder is fixedly connected to the left end of the sleeve. An adjusting bolt is threadedly connected to the outer wall of the threaded cylinder.

[0007] The sleeve has an adjusting pin fitted onto its inner wall, and a directional sleeve is movably connected to the right end of the sleeve. An expansion strip is provided on the right end of the directional sleeve.

[0008] Preferably, the cross-sectional area of ​​the inner wall of the threaded cylinder is adapted to the cross-sectional area of ​​the adjusting pin.

[0009] Preferably, the number of the adjusting pins, sleeves, and directional sleeves is four sets, and each set of adjusting pins, sleeves, and directional sleeves is symmetrically distributed on the left and right sides of the central axis of the positioning post in the horizontal direction with the central axis of the positioning post as the axis of symmetry.

[0010] Preferably, the cross-sectional area of ​​the end of the positioning pin is greater than the cross-sectional area of ​​the directional sleeve.

[0011] Preferably, the positioning post is fixedly connected to an auxiliary seat on its front surface, an auxiliary plate is hinged to the inner surface of the auxiliary seat, a strip groove is formed at the center of the front surface of the auxiliary plate, a rotating shaft is rotatably connected to the top of the left surface of the inner wall of the strip groove, a positioning pin is fixedly connected to the outer wall of the rotating shaft, an auxiliary nut is movably installed at the top corner of the front surface of the auxiliary plate, and an irregular groove is formed on the front surface of the auxiliary plate near the outer side of the strip groove.

[0012] Preferably, a triangular block is fixedly connected at the bottom corner of the inner wall of the irregular groove, and a protrusion is fixedly connected at the bottom opening of the inner wall of the irregular groove.

[0013] Preferably, the horizontal centerline of the auxiliary plate, the horizontal centerline of the rotating shaft, and the horizontal centerline of the positioning pin are located on the same straight line.

[0016] Preferably, the outer surface of the expansion strip has multiple sets of evenly distributed circular grooves.

[0017] Compared with the prior art, the present invention provides a rapid pre-fixing structure for curtain wall installation of building devices, which has the following beneficial effects:

[0018] 1. This building installation features a rapid pre-fixing structure for curtain wall installation. The positioning device allows for depth adjustment, making the positioning columns suitable for wall installations at various depths. This improves the applicability of the positioning device across different depth ranges and enhances its overall usability. Workers use external tools to tap the adjusting pins, causing them to move directionally until their ends fully enter the positioning holes, thus completing the installation and improving ease of installation. During installation, the tapping action causes the expansion strip at the end of the directional sleeve to expand outwards, pushing it into the inner wall of the positioning hole. This increases the contact area between the directional sleeve and the positioning hole, further enhancing the stability of the positioning device. The circular groove acting on the expansion strip increases friction after it embeds into the inner wall of the positioning hole, further improving the embedding effect and enhancing the positioning efficiency of the device.

[0019] 2. This building installation features a rapid pre-fixing structure for curtain wall installation. To improve the positioning accuracy of the device, the positioning slots are placed at the fixing points of the external fixing plates to be installed, thus confirming the position of the positioning columns. This process is repeated, using an electric telescopic rod in conjunction with the central body to adjust the distance between the positioning columns, ensuring that all four positioning columns are aligned with the fixing points of the external fixing plates to be installed. This confirms the distribution of the positioning columns, and the measured spacing data of the positioning columns is effectively recorded. This confirms the positioning holes for the fixing points of the external fixing plates to be installed, preventing rework and ensuring the subsequent erection of the fixing beams. This improves the ease of use of the positioning columns, accelerates the construction progress, and enhances the precision of the device.

[0020] 3. This building installation features a rapid pre-fixing structure for curtain wall installation. To improve the positioning effect, auxiliary nuts are removed, and the auxiliary plate is unfolded from the outer wall of the positioning column by adjusting the auxiliary seat. This unfolds and lays the plate in the recessed areas of the curtain wall, compensating for the contact area and increasing the effective area between the positioning column and the curtain wall surface. This improves the stability of the positioning column during installation. The positioning angle of the positioning nail is adjusted by rotating the pivot, which reinforces the fixation of the unfolded auxiliary plate. Workers can reinstall the removed auxiliary nuts from the back of the auxiliary plate to achieve positioning at the top corner of the auxiliary plate, improving the stability of the positioning column. The protrusions and triangular blocks in the irregular groove are at different heights, enhancing the embedding effect of the auxiliary plate, improving the positioning effect of the positioning column, and expanding the applicability of the positioning column.

[0021] 4. The building installation features a rapid pre-fixing structure for curtain wall installation. To enhance the functionality of the device, rubber pads, diagonal braces, and fixing seats are used to form a triangle between the electric telescopic rod and the positioning column. The stability of the triangle is utilized to enhance the stability of the positioning column. The suction cups installed increase the support of the center point when the positioning column is fixed to the external fixing plate, improving the convenience of secondary installation of the positioning column and the external fixing plate, and enriching the functionality of the device.

[0030] like Figure 1 - Figure 7As shown, the present invention provides a technical solution: a quick pre-fixing structure for curtain wall installation of building devices, including a central body 1, one end of an electric telescopic rod 2 is provided on the outer wall of the central body 1, the other end of the electric telescopic rod 2 is fixedly connected to a positioning column 5, a positioning device is provided inside the positioning column 5, the positioning device includes a sleeve 54 movably connected at the center of the front surface of the positioning column 5, a threaded cylinder 52 is fixedly connected to the left end of the sleeve 54, an adjusting bolt 53 is threadedly connected to the outer wall of the threaded cylinder 52, an adjusting nail 51 is sleeved on the inner wall of the sleeve 54, and a directional sleeve 55 is movably connected to the right end of the sleeve 54, with an expansion strip 56 provided at the right end of the directional sleeve 55.

[0031] In one embodiment of the present invention, the device is placed at the external fixing plate to be installed. The positioning groove 58 is placed at the fixing point of the external fixing plate to be installed, thereby confirming the position of the positioning column 5. This operation is repeated, and the distance between the positioning columns 5 is adjusted by the electric telescopic rod 2 in conjunction with the central body 1, so that all four positioning columns 5 are aligned with the fixing point of the external fixing plate to be installed. The distribution of the positioning columns 5 is confirmed, and the measured spacing data of the positioning columns 5 is effectively recorded. This confirms the positioning holes of the fixing point of the external fixing plate to be installed, preventing rework and affecting the subsequent erection of the fixing beam. This improves the ease of use of the positioning columns 5, speeds up the construction progress, and enhances the accuracy of the device during installation. Adjust the directional sleeve 55 until it is pushed into the designated positioning hole, then activate the positioning device. There are four sets of adjusting pins 51, sleeves 54, and directional sleeves 55. Each set of adjusting pins 51, sleeves 54, and directional sleeves 55 is symmetrically distributed on both sides of the horizontal axis of the positioning post 5, improving the stability of the sleeves 54. The operator can manually adjust the adjusting bolts 53. The adjusting bolts 53, in conjunction with the threaded sleeve 52, allow for different length extension and retraction adjustments of the positioning device in the positioning post 5. This provides adjustment during the installation of the positioning post 5, enabling the positioning device to be adjusted to different depths. Therefore, the positioning post 5 is suitable for wall installation at various depths. The positioning device is designed to accommodate different depths of the positioning pin 5, thus improving its applicability. The adjustment process via the adjusting bolt 53 and threaded sleeve 52 is very convenient, enhancing the ease of adjustment for different depths. When the operator uses an external tool to tap the adjusting pin 51, the cross-sectional area of ​​the inner wall of the threaded sleeve 52 matches the cross-sectional area of ​​the adjusting pin 51. The adjusting pin 51 moves directionally during the tapping process, ensuring its end fully enters the positioning hole, thereby completing the installation of the positioning device. This improves the ease of installation. During installation, the tapping action on the adjusting pin 51 by the operator further enhances its ease of use, as the cross-sectional area of ​​the adjusting pin 51's end is larger than that of the directional sleeve 55. The cross-sectional area of ​​the expansion strip 56 at the end of the directional sleeve 55 is increased, causing it to expand outwards under the action of the adjusting pin 51. This results in the expansion strip 56 tending to insert into the inner wall of the positioning hole, thus the outer wall of the expansion strip 56 acts on the inner wall of the positioning hole. When the adjusting pin 51 is embedded at the bottom of the inner wall of the positioning hole, the expansion strip 56 is tightly embedded in the inner wall of the positioning hole, increasing the contact area between the directional sleeve 55 and the positioning hole. This further enhances the stability of the positioning device and prevents it from detaching due to direct pulling by external forces. Multiple sets of evenly distributed circular grooves 57 are formed on the outer surface of the expansion strip 56. The circular grooves 57 act on the expansion strip 56, increasing the friction between the expansion strip 56 and the inner wall of the positioning hole after the expansion strip 56 is embedded in the inner wall.This further improves the embedding effect of the expansion strip 56 into the inner wall of the positioning hole, thus enhancing the positioning effect of the positioning device.

[0032] In addition, to improve the positioning effect of the device, an auxiliary seat 6 is fixedly connected to the front surface of the positioning post 5. An auxiliary plate 61 is hinged to the inner surface of the auxiliary seat 6. A strip groove 63 is opened at the center of the front surface of the auxiliary plate 61. A rotating shaft 64 is rotatably connected to the top of the left surface of the inner wall of the strip groove 63. A positioning nail 65 is fixedly connected to the outer wall of the rotating shaft 64. An auxiliary nut 62 is movably installed at the top corner of the front surface of the auxiliary plate 61. A special groove 66 is opened on the outer side of the front surface of the auxiliary plate 61 near the strip groove 63. When the positioning post 5 needs to be installed in the recessed area of ​​the curtain wall, the auxiliary nut 62 is removed. By adjusting the auxiliary seat 6, the horizontal central axis of the auxiliary plate 61, the horizontal central axis of the rotating shaft 64, and the horizontal central axis of the positioning nail 65 are all on the same straight line, which improves the stability of the auxiliary plate 61. This allows the auxiliary plate 61 to unfold from the outer wall of the positioning post 5 and unfold to pave the recessed area of ​​the curtain wall, compensating for the contact area of ​​the recessed area of ​​the curtain wall, increasing the effective area between the positioning post 5 and the curtain wall surface, and improving the positioning effect of the positioning post 5. To ensure stability during installation, after the auxiliary plate 61 is unfolded, the positioning angle of the positioning pin 65 can be adjusted by rotating the shaft 64, which strengthens the fixation of the unfolded auxiliary plate 61. At the same time, the worker can reinstall the disassembled auxiliary nut 62 from the back of the auxiliary plate 61 to achieve positioning at the top corner of the auxiliary plate 61, thus improving the stability of the positioning post 5. When cement is poured and fixed around the positioning post 5, the irregular groove 66 is provided with a hollow wave-shaped structure. The irregularity of the contact surface and the embedding surface is increased by the irregular groove 66 in the auxiliary plate 61, making the cement more attractive to the positioning of the auxiliary plate 61. A triangular block 68 is fixedly connected at the bottom corner of the inner wall of the irregular groove 66, and a protrusion 67 is fixedly connected at the bottom groove opening of the inner wall of the irregular groove 66. The protrusion 67 and the triangular block 68 in the irregular groove 66 are at different heights, which enhances the embedding effect of the auxiliary plate 61, enhances the positioning effect of the positioning post 5, and improves the applicability of the positioning post 5.

[0033] In the embodiments of the present invention, to enrich the functionality of the device, a mounting base 3 is fixedly connected to the front surface of the central body 1, a suction cup 4 is movably connected to the inner wall of the mounting base 3, a fixing base 23 is fixedly installed on the right surface of the positioning post 5, one end of a diagonal rod 22 is fixedly connected to the right surface of the fixing base 23, and a rubber pad 21 is fixedly connected to the other end of the diagonal rod 22. After the positioning post 5 is installed, the rubber pad 21, together with the diagonal rod 22 and the fixing base 23, forms a triangle with the electric telescopic rod 2 and the positioning post 5. The stability of the triangle is utilized to prevent the positioning post 5 from deforming under long-term force, thus preventing the positioning post 5 from detaching from the electric telescopic rod 2, thereby enhancing the stability of the positioning post 5. The suction cup 4 increases the support of the center point when the positioning post 5 is fixed to the external fixing plate, improving the convenience of secondary installation of the positioning post 5 and the external fixing plate, and enriching the functionality of the device.

[0034] In this invention, during use, the device is placed at the desired external fixing plate. The positioning groove 58 is positioned at the fixing point of the external fixing plate to confirm the position of the positioning column 5. This process is repeated, using the electric telescopic rod 2 in conjunction with the central body 1 to adjust the distance between the positioning columns 5, ensuring that all four positioning columns 5 are aligned with the fixing point of the desired external fixing plate. This confirms the distribution of the positioning columns 5. The measured spacing data of the positioning columns 5 is effectively recorded, thus confirming the positioning holes for the fixing points of the desired external fixing plate. This prevents rework and ensures the subsequent erection of the fixing beam, improving the ease of use of the positioning columns 5, accelerating construction progress, and enhancing the accuracy of the device during installation. During the process, the directional sleeve 55 is adjusted and pushed into the designated positioning hole. The positioning device is then activated. The operator can manually adjust the adjusting bolt 53. The adjusting bolt 53, in conjunction with the threaded cylinder 52, allows for different length extension and retraction adjustments of the positioning device within the positioning post 5. This adjustment function during the installation of the positioning post 5 enables the positioning device to be adjusted to different depths, making the positioning post 5 suitable for wall installations at various depths. This improves the applicability of the positioning device to different depth ranges of the positioning post 5. The adjustment process using the adjusting bolt 53 and threaded cylinder 52 is very convenient. Alternatively, the operator can use an external tool to tap the adjusting nail 51, causing it to move in a directional direction during the tapping process. The adjustment pin 51 is moved so that its end is fully inserted into the positioning hole, thus completing the installation of the positioning device. During the installation process, the adjustment pin 51 is tapped by the workers, causing the expansion strip 56 at the end of the directional sleeve 55 to expand outwards under the action of the adjustment pin 51. This causes the expansion strip 56 in the positioning hole to tend to insert into the inner wall of the positioning hole. As a result, the outer wall of the expansion strip 56 acts on the inner wall of the positioning hole, so that when the adjustment pin 51 is embedded in the bottom of the inner wall of the positioning hole, the expansion strip 56 is tightly embedded in the inner wall of the positioning hole. This increases the contact area between the directional sleeve 55 and the positioning hole, preventing the positioning device from detaching due to direct pulling by external forces. The circular groove 57 acts on the expansion strip 56, causing the expansion strip 56 to embed... The increased friction between the expansion strip 56 and the inner wall of the positioning hole increases the positioning post 5's position in the recessed area of ​​the curtain wall. When the positioning post 5 needs to be installed in the recessed area of ​​the curtain wall, the auxiliary nut 62 is removed, and the auxiliary plate 61 is unfolded from the outer wall of the positioning post 5 by adjusting the auxiliary seat 6. This unfolds and lays the plate in the recessed area of ​​the curtain wall, compensating for the contact area and increasing the effective area between the positioning post 5 and the curtain wall surface. After the auxiliary plate 61 is unfolded, the positioning angle of the positioning nail 65 is adjusted by rotating the pivot 64, which reinforces the fixation of the unfolded auxiliary plate 61. The worker can then reinstall the removed auxiliary nut 62 from the back of the auxiliary plate 61 to achieve positioning at the top corner of the auxiliary plate 61. When cement is poured around the positioning post 5 for fixation...The irregularity of the contact and embedding surfaces is increased by the irregular groove 66 in the auxiliary plate 61, making the cement more adhesive to the positioning of the auxiliary plate 61. The protrusions 67 and triangular blocks 68 in the irregular groove 66 are at different heights, enhancing the embedding effect of the auxiliary plate 61 and the positioning effect of the positioning post 5. After the positioning post 5 is installed, the rubber pad 21, together with the diagonal rod 22 and the fixing seat 23, forms a triangle with the electric telescopic rod 2 and the positioning post 5. The stability of the triangle prevents the positioning post 5 from deforming under long-term force, thus preventing it from detaching from the electric telescopic rod 2 and enhancing its stability. The suction cup 4 added to the support of the center point when the positioning post 5 is fixed to the external fixing plate, enriching the functionality of the device.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
