Description

Technical Field

[0001] This invention relates to the field of building curtain wall installation technology, and in particular to a positioning device for a steel structure spherical curved surface curtain wall support. Background Technology

[0002] Currently, architectural designs are becoming increasingly unique, and the requirements for appearance are also getting higher and higher. It is common to use irregularly shaped curtain walls on the outside to enhance the appearance of buildings.

[0003] The installation and positioning of supports for spherical glass curtain walls has always been a relatively tricky problem. Because the curtain wall glass is prefabricated, it needs to be assembled directly on site. If there is a large error in the installation of the curtain wall supports, the entire spherical curved glass will not be able to be installed in the correct position. Therefore, the requirements for the layout and positioning of the supports are extremely high. The traditional method of positioning the curtain wall supports is to use a steel ruler to measure the distance. However, this method is not very practical for spherical curved glass curtain walls. This results in large errors in the installation of the curtain wall supports on each steel structure, leading to excessively large joints in the installation of the spherical glass curtain wall, which affects the aesthetics and stability. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a steel structure spherical curved surface curtain wall support positioning device, which solves the problem that the traditional curtain wall support positioning method uses a steel ruler to measure the distance during installation, but this method has a large error in the installation of the curtain wall support, resulting in excessively large joints in the installation of the spherical glass curtain wall.

[0005] According to an embodiment of the present invention, a positioning device for a steel structure spherical curved curtain wall support includes a mounting plate with a column passing through it. The column is located in the center of the mounting plate, and four supports are evenly distributed on the lower side of the mounting plate. An auxiliary device includes a telescopic member movably mounted on the column and a positioning grab disposed at one end of the telescopic member. A limit seat is disposed on the upper part of the column, and the auxiliary device is located on the upper side of the limit seat and abuts against it. The telescopic member is used to adjust the measuring length of the auxiliary device, the positioning grab is used to determine the installation position of the curtain wall support on the steel structure, and the limit seat is used to adjust the position of the auxiliary device on the column. A positioning device is movably disposed at the lower end of the column and located directly below the mounting plate, and is used to determine the relative position of the column.

[0006] Compared with existing technologies, this invention has the following advantages: During the installation of the spherical curved curtain wall, the center and radius of the steel structure used for installing the spherical curved curtain wall are visualized through the setting of the telescopic component and the positioning grabber. In use, the positioning device is aligned with the center point of the top view projection of the steel structure, and the auxiliary device on the column is adjusted to be located at the center of the spherical steel structure. Then, the telescopic component is extended to the spherical steel structure to determine the installation position of the curtain wall support on the spherical steel structure, ensuring that the extension line of each set of curtain wall supports installed on the steel structure passes through the center of the sphere, and ensuring that the curtain wall supports installed on the spherical steel structure are on the same arc surface. This solves the technical problem of excessively large splice seams in the installation of spherical glass curtain walls caused by non-standard installation of curtain wall supports.

[0027] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] like Figures 1 to 10As shown in the figure, this embodiment of the invention proposes a positioning device for a steel structure spherical curved curtain wall support, including a mounting plate 1 with a column 2 passing through it. The column 2 is located in the center of the mounting plate 1, and four supports 101 are evenly distributed on the lower side of the mounting plate 1; an auxiliary device including a telescopic member movably mounted on the column 2 and a positioning grab 6 mounted on one end of the telescopic member. A limit seat is provided on the upper part of the column 2, and the auxiliary device is located on the upper side of the limit seat and abuts against it. The telescopic member is used to adjust the measuring length of the auxiliary device, the positioning grab 6 is used to determine the installation position of the curtain wall support on the steel structure, and the limit seat is used to adjust the position of the auxiliary device on the column 2; a positioning device is movably mounted on the lower end of the column 2 and located on the lower side of the mounting plate 1, and is used to determine the relative position of the column 2.

[0029] The detailed working process of this embodiment is as follows: The function of the column 2 is to facilitate the movement of the auxiliary device to meet the needs of spherical steel structures 801 of different sizes. The limiting seat is used to limit the auxiliary device after the center 800 of the sphere is determined, so that it is located at the center 800 of the spherical steel structure 801. The function of the telescopic component is to visualize the radius of the spherical steel structure 801. The function of the positioning claw 6 is to be locked on the spherical steel structure 801. The two work together to facilitate the determination of the installation position of the curtain wall support 802. The function of the positioning device is to determine the center point of the top view projection of the steel structure 801 and place the positioning device at the center point.

[0030] During the installation of the spherical curved curtain wall, the center 800 and radius of the steel structure 801 used for installing the spherical curved curtain wall are visualized through the setting of the telescopic component and the positioning claw 6. In use, first determine the center point of the top-view projection of the steel structure 801, then align the positioning device with the center point of the top-view projection of the steel structure 801. Adjust the auxiliary device on the column 2 to position it at the center 800 of the spherical steel structure 801. Then, use the limiting seat to limit the auxiliary device located at the center 800. Next, extend the telescopic component onto the spherical steel structure 801 and lock the positioning claw 6 onto the spherical steel structure 801 (as shown in the example). Figure 10 As shown in the figure, this is used to determine the installation position of the curtain wall support 802 on the spherical steel structure 801, ensuring that the extension line of each set of curtain wall supports 802 installed on the steel structure 801 passes through the center of the sphere 800, so that the curtain wall supports 802 installed on the spherical steel structure 801 are on the same arc surface. This solves the technical problem of excessively large splice seams in the installation of spherical glass curtain walls caused by non-standard installation of curtain wall supports 802.

[0031] like Figures 2 to 4As shown, the telescopic component includes a measuring rod 3 and an extension arm 5. A movable seat 201 is slidably mounted on the upper part of the column 2. One end of the measuring rod 3 is hinged to the movable seat 201. The extension arm 5 is slidably mounted inside the measuring rod 3 through an adjusting component. The adjusting component is used to adjust the extension length of the extension arm 5. A sliding groove 301 is provided inside the measuring rod 3. A locking block 502 is provided at one end of the extension arm 5. The locking block 502 is located inside the sliding groove 301. A positioning grabber 6 is fixedly mounted at the end of the extension arm 5 away from the locking block 502.

[0032] The detailed working process of this embodiment is as follows: The movable seat 201 is used to connect the column 2 and the measuring rod 3. The movable seat 201 can move up and down and rotate on the column 2. The measuring rod 3 can swing on the movable seat 201. The extension arm 5 is located inside the measuring rod 3 and can be pulled out to increase the working length of the measuring rod 3 to meet the working needs. The function of the locking block 502 and the slide groove 301 is to prevent the extension arm 5 from rotating inside the measuring rod 3, and at the same time to limit the extension arm 5 to prevent it from being completely pulled out of the extension arm 5 and affecting its use.

[0033] like Figure 5 and Figure 6 As shown, the adjusting component includes a rotating shaft 501 and a conical seat 504. The rotating shaft 501 is driven within the extension arm 5. One end of the rotating shaft 501 is threaded. The conical seat 504 is threaded to the threaded end of the rotating shaft 501. A conical hole 302 is provided inside the end of the extension arm 5 away from the positioning gripper 6. A cross-shaped U-groove 303 is provided at the end of the extension arm 5 with the conical hole 302. The conical seat 504 is located within the conical hole 302. A limiting groove 304 is provided within the conical hole 302. A limiting strip 503 is provided on the conical seat 504 and is located within the limiting groove 304.

[0034] The detailed working process of this embodiment is as follows: The rotating shaft 501 is driven and installed inside the extension arm 5. The unthreaded end extends out of the extension arm 5 and is rotatably mounted on the positioning gripper 6. Operation is performed by rotating the end of the extension arm 5. The tapered hole 302 inside the extension arm 5 is used to place the tapered seat 504. With the setting of the limiting strip 503 and the limiting groove 304, the tapered seat 504 can move back and forth in the tapered hole 302 but cannot rotate. The end of the extension arm 5 with the tapered hole 302 is provided with a cross U-shaped groove 303. With the setting of the cross U-shaped groove 303, the end of the extension arm 5 with the tapered hole 302 is evenly distributed. Divided into four segments, the tapered seat 504 is threadedly connected to the threaded end of the rotating shaft 501. When the rotating shaft 501 is rotated, the tapered seat 504 will move forward or backward. When the tapered seat 504 moves within the tapered hole 302, it will expand into four segments of the extension arm 5 under the action of compression, so that it abuts against the inside of the measuring rod 3, thereby controlling the position of the extension arm 5 within the measuring rod 3. When the extension arm 5 needs to be adjusted, the rotating shaft 501 is rotated in the opposite direction to control the tapered seat 504 to move backward. When one end of the expanded four segments of the extension arm 5 is no longer compressed by the tapered seat 504, it will spring back to its original position under its own elasticity, and then adjustment can be made.

[0035] The purpose of placing the operating end of the rotating shaft 501 close to the positioning gripper 6 is to facilitate the operation of the personnel installing the curtain wall support 802 on the spherical steel structure 801.

[0036] like Figure 2 and Figure 7 As shown, the limiting seat includes an adjusting seat 7 and a pressing handle 704. The adjusting seat 7 is sleeved on the column 2 and located below the movable seat 201. A movable shaft 703 is provided on the adjusting seat 7. The pressing handle 704 is hinged to one end of the movable shaft 703. A compression spring 702 is sleeved on the movable shaft 703 and is located inside the adjusting seat 7.

[0037] The detailed working process of this embodiment is as follows: The adjusting seat 7 has an opening, and the pressing handle 704 is used to press the opening on the adjusting seat 7 to bring it closer, so as to change its inner diameter, so that the adjusting seat 7 can be firmly clamped on the column 2 and will not slip off. The end of the pressing handle 704 that contacts the adjusting seat 7 is similar to a cam pressing and pressing. When adjustment is needed, simply pull up the pressing handle 704, and the opening on the adjusting seat 7 will open under its own elasticity and the elastic force of the compression spring 702, increasing its inner diameter, so that it can move on the column 2.

[0038] like Figure 2 and Figure 8 As shown, the positioning device includes a positioning rod 4, which is movably disposed inside the lower part of the column 2. An L-shaped groove 202 is provided on the column 2, which is located on the lower side of the mounting plate 1. A limit block 401 is provided at the upper end of the positioning rod 4, which is located inside the L-shaped groove 202.

[0039] like Figure 2 As shown, the lower end of the positioning rod 4 is tapered.

[0040] The detailed working process of this embodiment is as follows: The purpose of the tapered lower end of the positioning rod 4 is to align it with the center point of the top view projection of the steel structure 801, reducing errors. The positioning rod 4 can extend and retract inside the lower part of the column 2 to protect the positioning rod 4 during movement and prevent it from being damaged, thus affecting its accuracy in use. The function of the limiting block 401 is to limit the positioning rod 4 inside the lower part of the column 2, making it easier to operate the positioning rod 4. When the positioning rod 4 needs to be lowered, rotate the positioning rod 4 so that the limiting block 401 can move up and down in the L-shaped groove 202, so that the limiting block 401 can be lowered to align it with the center point of the top view projection of the steel structure 801. When it needs to be retracted, retract the limiting block 401 into the column 2, and then rotate it so that the limiting block 401 is locked at one end of the L-shaped groove 202.

[0041] like Figure 7 As shown, an anti-slip sleeve 701 is provided inside the adjusting seat 7.

[0042] The detailed working process of this embodiment is as follows: The function of the anti-slip sleeve 701 is to prevent the adjustment seat 7 and the column 2 from making direct hard contact and causing wear, while increasing the friction between them.

[0043] like Figure 9 As shown, the upper end of column 2 is bolted with an anti-detachment plate 203.

[0044] The detailed working process of this embodiment is as follows: The function of the anti-detachment plate 203 is to prevent the movable seat 201 on the column 2 from being pulled out of the column 2 and affecting its use.

[0045] like Figure 1 As shown, each bracket 101 is equipped with a caster wheel 102 at its bottom.

[0046] The detailed working process of this embodiment is as follows: The function of the caster wheel 102 is to facilitate adjustment, so as to save time and reduce the workload when the positioning rod 4 and the center point of the top view projection of the steel structure 801 are aligned. The caster wheel 102 used in this embodiment has a self-locking function to prevent the positioning rod 4 from being displaced due to shaking after alignment.

[0047] like Figure 3 As shown, the positioning grabber 6 has two positioning strips 601 inside.

[0048] The detailed working process of this embodiment is as follows: The function of the two positioning strips 601 is to ensure that the steel structure 801 inside the positioning grab 6 can be located in the exact center of the positioning grab 6, thereby improving the installation accuracy of the curtain wall support 802.

[0049] The implementation principle of this application embodiment is as follows: In use, first determine the center point of the top view projection of the steel structure 801, then align the positioning rod 4 with the center point of the top view projection of the steel structure 801, adjust the movable seat 201 on the column 2 so that it is located at the center 800 of the spherical steel structure 801, then use the adjusting seat 7 to limit the movable seat 201 located at the center 800, then stretch the extension arm 5 from the measuring rod 3 to the spherical steel structure 801, rotate the rotating shaft 501, the conical seat 504 will move forward, and when the conical seat 504 moves in the conical hole 302, it will be stretched into four parts of the extension arm 5 under the action of compression, so that it abuts and fixes against the inside of the measuring rod 3, and then the positioning claw 6 is locked on the spherical steel structure 801, so that the center and radius of the steel structure 801 for installing the spherical curved curtain wall can be visualized.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
