Summary of the invention

[0003] In view of this, the object of the present invention is to provide a glass curtain wall column installation auxiliary positioning device to solve the technical problem in the prior art that the selected installation position is reflected on the curved aluminum plate.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] Furthermore, the drive unit includes a gear coaxially arranged on the corresponding drive column; each arc support plate is hinged with a rack meshing with the corresponding gear; a second tension spring is connected between each rack and the arc support plate, and the second tension spring enables the rack to always mesh with the corresponding gear.

[0009] Furthermore, the free end of the extended strip is connected to a fixed plate; and a positioning strip capable of fitting with the plane side wall of the arc-shaped aluminum plate is rotatably connected between the opposite side walls of the fixed plate.

[0010] A method for using a glass curtain wall column installation auxiliary positioning device comprises the following steps:

[0011] S1: Slide the auxiliary positioning device onto the arc-shaped main bone, slide the sliding frame along the arc-shaped main bone and select the installation

[0012] Location;

[0013] S2: Use the slider to drive the U-shaped frame to slide away from the center of the arc-shaped aluminum plate to expose the limit strip;

[0014] S3: Using the rotating shaft to drive the two fixing bars to rotate in a direction away from the sliding frame, so that the two fixing bars are placed on the outer arc wall of the arc-shaped aluminum plate;

[0015] S4: Rotate the U-shaped frame so that the two fixing bars are in the same horizontal plane, so that the two fixing bars are parallel to the transverse main bone;

[0016] S5: Slide the two fixing bars on the limit bar and adjust the relative distance between the two fixing bars so that the relative distance is consistent with the glass curtain.

[0017] The wall studs are the same width;

[0018] S6: Install glass curtain wall columns on the curved aluminum plate according to the relative distance of the fixing strips.

[0019] The beneficial effects of the present invention are:

[0020] 1. Let the sliding frame slide on the arc-shaped main bone. When it reaches the selected installation position, use the slider to drive the U-shaped frame to slide away from the center of the arc-shaped aluminum plate, so that the limit strip is exposed. Then use the rotating shaft to drive the two fixed strips to rotate more than half a circle away from the sliding frame, so that the two fixed strips are placed on the outer arc wall of the arc-shaped aluminum plate; rotate the U-shaped frame so that the two fixed strips are located in the same horizontal plane and parallel to the horizontal main bone; slide the two fixed strips on the limit strip, adjust the relative position of the two fixed strips, so that the distance between the two matches the width of the glass curtain wall column; install the glass curtain wall column on the arc-shaped aluminum plate according to the relative distance of the fixed strips. Adjust the relative distance of the two fixed strips to be equal to the width of the glass curtain wall column, and place the two fixed strips on the arc-shaped aluminum plate. The selected installation position can be directly reflected on the arc-shaped aluminum plate through the fixed strips, thereby facilitating the installation of the glass curtain wall column.

[0021] 2. Compared with setting the sliding frame on the curved aluminum plate, the advantage of sliding the sliding frame on the curved main frame is that the installation order can be selected, and it can be installed from one side of the curved aluminum plate to the other side. Since the fixing bar can be rotated through the shaft, after installing the middle glass curtain wall column, the fixing bar is rotated away from the curved aluminum plate and the next installation position is selected through the sliding frame, so it can also be installed from the center of the curved aluminum plate to both sides.

[0022] 3. The advantage of rotatably connecting the U-shaped frame to the slider is that no matter where the sliding frame slides on the arc-shaped main bone, the two fixing bars can be kept in a vertical state by rotating the U-shaped frame, thereby avoiding skewing when installing the glass curtain wall columns; at the same time, the U-shaped frame is also slidably connected to the sliding frame by the slider, so that when the two fixing bars are swung to rest on the arc-shaped aluminum plate, the fixing bars can always be vertically resting on the outer arc wall of the arc-shaped aluminum plate; because the two fixing bars are slidably set on the limit bar, when the fixing bars are resting on the edge position of the arc-shaped aluminum plate, only when one fixing bar rests on the outer arc wall of the arc-shaped aluminum plate, under the limiting action of the limit bar, the other fixing bar can remain parallel to the fixing bar resting on the arc-shaped aluminum plate even if it is in a suspended state, so that the two fixing bars are in a state of the same horizontal plane, avoiding the two fixing bars from deviating, thereby avoiding the glass curtain wall columns from deviating when being installed.

[0023] 4. By setting two arc support plates, the outer arc surface of the arc support plate is in contact with the outer arc wall of the arc-shaped aluminum plate, and the original contact between the protruding strip and the arc-shaped aluminum plate is changed to a contact between two and one. Since the arc support plate is in a hinged state, the arc support plate can better fit the outer arc wall of the arc-shaped aluminum plate. Even if wear occurs, since the contact position of the arc support plate is different each time, the protruding strip can be avoided from tilting, so that the protruding strip is kept in the same horizontal plane, which can avoid errors in the installation of glass curtain wall columns; at the same time, the setting of the first spring can reduce the vibration caused by the direct contact between the arc support plate and the outer arc wall of the arc-shaped aluminum plate.

[0024] 5. When the rotating shaft drives the fixed bar to swing up for most of a circle, the arc support plate and the arc-shaped aluminum plate will vibrate when in contact. Under the action of the first spring, the support bar will move repeatedly until the potential energy of the first spring is released. Such waiting is a great waste of time for the installation of the glass curtain wall columns. In order to stop the movement of the support bar quickly and improve the installation efficiency of the glass curtain wall columns, the driving unit is used to extend the clamping block out of the clamping groove and clamp it against the side wall of the positioning groove, thereby hindering the repeated movement of the support bar and keeping the extended bar still, which is more convenient for the installation of the glass curtain wall columns.

[0025] Other advantages, objectives and features of the present invention will be described in the following description and will be apparent to those skilled in the art to some extent, or those skilled in the art may be taught from the practice of the present invention. The objectives and other advantages of the present invention may be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] like Figures 1 to 6 As shown, the present invention provides an auxiliary positioning device for installing glass curtain wall columns, comprising a sliding frame 8 slidably arranged on the side of the arc-shaped main frame 3 away from the arc-shaped aluminum plate 4; a sliding block is slidably connected to the side wall of the sliding frame 8 away from the arc-shaped aluminum plate 4 along the radial direction of the arc-shaped aluminum plate 4; a U-shaped frame 9 parallel to the sliding frame 8 is rotatably connected to the sliding block; a limiting strip 10 is arranged between the opposite side walls in the U-shaped frame 9; the two ends of the limiting strip 10 are respectively rotatably connected to the side walls of the U-shaped frame 9 through a rotating shaft; two fixing strips 11 are slidably arranged on the limiting strip 10; the sliding block can drive the U-shaped frame 9 to slide, so that the limiting strip 10 is away from the sliding frame 8, and when the rotating shaft drives the limiting strip 10 to rotate, the fixing strip 11 can swing in the direction away from the sliding frame 8 and contact the outer arc wall of the arc-shaped aluminum plate 4.

[0035] The principle and beneficial effects of the above technical solution:

[0036] When installing the glass curtain wall column 5, it is necessary to select an installation position on the curved aluminum plate 4. In order to solve this problem, the sliding frame 8 is allowed to slide on the curved main bone 3. When it reaches the selected installation position, the slider is used to drive the U-shaped frame 9 to slide in the direction away from the center of the curved aluminum plate 4, so that the limiting strip 10 is exposed, and then the two fixing strips 11 are driven by the rotating shaft to rotate more than half a circle in the direction away from the sliding frame 8, so that the two fixing strips 11 are placed on the outer arc wall of the curved aluminum plate 4; the U-shaped frame 9 is rotated so that the two fixing strips 11 are located in the same horizontal plane and parallel to the transverse main bone; the two fixing strips 11 are slid on the limiting strip 10, and the relative positions of the two fixing strips 11 are adjusted so that the distance between the two matches the width of the glass curtain wall column 5; the glass curtain wall column 5 is installed on the curved aluminum plate 4 according to the relative distance of the fixing strips 11. The relative distance between the two fixing strips 11 is adjusted to be equal to the width of the glass curtain wall column 5 , and the two fixing strips 11 are placed on the curved aluminum plate 4 , so that the selected installation position can be intuitively reflected on the curved aluminum plate 4 through the fixing strips 11 , thereby facilitating the installation of the glass curtain wall column 5 .

[0037] The advantage of rotatably connecting the U-shaped frame 9 to the slider is that no matter where the sliding frame 8 slides on the arc-shaped main bone 3, the two fixing bars 11 can be kept in a vertical state by rotating the U-shaped frame 9, thereby avoiding skewing when installing the glass curtain wall column 5; at the same time, the U-shaped frame 9 is also slidably connected to the sliding frame 8 by the slider, so that when the two fixing bars 11 are swung to rest on the arc-shaped aluminum plate 4, the fixing bars 11 can always be vertically resting on the outer arc wall of the arc-shaped aluminum plate 4; The fixing strip 11 is slidably arranged on the limiting strip 10. When the fixing strip 11 is placed on the edge of the curved aluminum plate 4, only when one fixing strip 11 is placed on the outer arc wall of the curved aluminum plate 4, under the limiting effect of the limiting strip 10, the other fixing strip 11 can remain parallel to the fixing strip 11 placed on the curved aluminum plate 4 even if it is in a suspended state, so that the two fixing strips 11 are in the same horizontal plane, avoiding the two fixing strips 11 from shifting, thereby avoiding the glass curtain wall column 5 from shifting during installation.

[0038] In this embodiment, Figure 2 , 3 As shown in 4, a fixing groove is opened in the fixing bar 11; an extending bar 12 is slidably arranged in the fixing groove; a positioning groove 13 is opened on the side wall of the extending bar 12 away from the sliding frame 8; a support bar 14 is slidably connected to the positioning groove 13 through a first spring; one end of the support bar 14 away from the first spring is hingedly connected to two symmetrically arranged arc support plates 15, the length direction of the arc support plate 15 is perpendicular to the support bar 14, and the outer arc surface of the arc support plate 15 can contact the outer arc wall of the arc-shaped aluminum plate 4.

[0039] The principle and beneficial effects of the above technical solution:

[0040] The setting of the extended strip 12 can extend the length of the fixed strip 11, so that the extended strip 12 exposes a longer length of the curved aluminum plate 4, which can facilitate the positioning of the glass curtain wall column 5 when installing the glass curtain wall column 5; each time the extended strip 12 is stuck on the arc outer wall of the curved aluminum plate 4, the side wall where the extended strip 12 contacts the arc side wall of the curved aluminum plate 4 will produce arc-shaped wear, forming a concave groove. Over time, when the extended strip 12 is placed on the outer arc wall of the curved aluminum plate 4, the extended strip 12 will be offset and cannot remain in the same horizontal plane, so that the extended strip 12 becomes inclined and cannot achieve the auxiliary positioning effect on the glass curtain wall column 5. Even if the extended strip 12 is adjusted to a state parallel to the longitudinal main bone 2 by rotating the U-shaped frame 9, due to the guiding effect of the concave groove, the extended strip 12 will return to the inclined contact state. In order to solve this problem:

[0041] By setting two arc support plates 15, the outer arc surface of the arc support plate 15 is in contact with the outer arc wall of the arc-shaped aluminum plate 4, and the original contact between the protruding strip 12 and the arc-shaped aluminum plate 4 is changed to a contact between two and one. Since the arc support plate 15 is in a hinged state, the arc support plate 15 can better fit the outer arc wall of the arc-shaped aluminum plate 4. Even if wear occurs, since the contact position of the arc support plate 15 is different each time, the protruding strip 12 can be avoided from being tilted, so that the protruding strip 12 remains in the same horizontal plane, which can avoid errors in the installation of the glass curtain wall column 5; at the same time, the provision of the first spring can reduce the vibration caused by the direct contact between the arc support plate 15 and the outer arc wall of the arc-shaped aluminum plate 4.

[0042] In this embodiment, Figure 4 , 5 As shown, the two sides of the support bar 14 are rotatably connected with driving columns 16 distributed along the length direction of the arc support plate 15; a plurality of tightening grooves are opened on the circumferential side of each driving column 16; a tightening block 17 is slidably connected in each tightening groove through a second spring; a transition block 18 is connected between the tightening block 17 and the second spring; the transition block 18 has a slot perpendicular to the sliding direction of the tightening block 17; a starting slot 19 is opened on the side wall of the tightening groove and is located in the same straight line as the slot; a wedge block 20 that is inserted into the slot is slidably connected in the slot through a third spring; the wedge-shaped surface of the wedge block 20 is exposed in the slot; a starting block 21 that can push the wedge block 20 out of the slot is slidably connected in the tightening groove through a first tension spring; the sliding direction of the starting block 21 is perpendicular to the sliding direction of the wedge block 20; the wedge-shaped surface of the wedge block 20 faces the starting block 21; a driving unit that can drive the tightening block 17 to extend out of the tightening groove and tighten against the side wall of the positioning groove 13 is provided on the driving column 16.

[0043] The principle and beneficial effects of the above technical solution:

[0044] When the rotating shaft drives the fixed bar 11 to swing more than half a circle, the arc support plate 15 contacts the arc-shaped aluminum plate 4 and generates vibration. Under the action of the first spring, the support bar 14 will move repeatedly until the potential energy of the first spring is released. Such waiting is extremely wasteful of the installation time of the glass curtain wall column 5. In order to allow the support bar 14 to stop moving quickly and improve the installation efficiency of the glass curtain wall column 5, the driving unit is used to extend the tightening block 17 out of the tightening groove and tighten against the side wall of the positioning groove 13, thereby hindering the repeated movement of the support bar 14 and keeping the extended bar 12 still, so as to facilitate the installation of the glass curtain wall column 5.

[0045] In this embodiment, Figure 4As shown, the drive unit includes a gear (not shown in the figure) coaxially arranged on the corresponding drive column 16; each arc support plate 15 is hinged with a rack 22 meshing with the corresponding gear on the side facing the support bar 14; a second tension spring 23 is connected between each rack 22 and the arc support plate 15, and the second tension spring 23 enables the rack 22 to always mesh with the corresponding gear.

[0046] The principle and beneficial effects of the above technical solution:

[0047] When the arc support plate 15 is in contact with the outer arc wall of the arc-shaped aluminum plate 4, the hinged rack 22 will be driven to move, thereby driving the driving column 16 to rotate through the gear. Under the action of centrifugal force, the starting block 21 will slide in the direction away from the first tension spring, thereby contacting the wedge surface of the wedge block 20 and pushing the wedge block 20 out of the slot. Then the second spring will drive the clamping block 17 to slide out of the clamping slot, so that the clamping block 17 is pressed against the side wall of the positioning slot 13, thereby hindering the repeated movement of the support bar 14, and the extended bar 12 remains stationary, which makes it easier to install the glass curtain wall column 5.

[0048] In this embodiment, Figure 3 As shown, the free end of the extending strip 12 is connected to a fixing plate; a positioning strip 24 capable of fitting with the plane side wall of the arc-shaped aluminum plate 4 is rotatably connected between the opposite side walls of the fixing plate.

[0049] The principle and beneficial effects of the above technical solution:

[0050] When the arc support plate 15 is placed on the arc outer wall of the arc-shaped aluminum plate 4 , the positioning bar 24 is controlled to rotate so that the positioning bar 24 is vertically attached to the plane side wall of the arc-shaped aluminum plate 4 , thereby facilitating the positioning and installation of the glass curtain wall column 5 .

[0051] Another object of the present invention is to provide a method for using a glass curtain wall column installation auxiliary positioning device, comprising the following steps:

[0052] S1: Slidingly install the auxiliary positioning device on the arc-shaped main bone 3, sliding the sliding frame 8 along the arc-shaped main bone 3 and selecting the installation position;

[0053] S2: After reaching the installation position, the U-shaped frame 9 is driven by the slider to slide in a direction away from the center of the arc-shaped aluminum plate 4, so that the limit bar 10 is exposed, providing space for the rotation of the fixing bar 11, so that the fixing bar 11 can be placed on the outer arc wall of the arc-shaped aluminum plate 4 after rotation;

[0054] S3: Use the rotating shaft to drive the two fixing bars 11 to rotate in a direction away from the sliding frame 8, so that the fixing bars 11 are placed on the outer arc wall of the arc-shaped aluminum plate 4, so that the selected installation position can be reflected on the arc-shaped aluminum plate 4 through the fixing bars 11, thereby facilitating the subsequent installation of the glass curtain wall columns 5;

[0055] S4: Rotate the U-shaped frame 9 so that the two fixing bars 11 are located at the same horizontal plane, so that the two fixing bars 11 are parallel to the transverse main bone 1. The glass curtain wall column 5 is usually installed vertically. In order to avoid tilting after installation, the position is corrected by rotating the U-shaped frame 9 to make it in a vertical state;

[0056] S5: Sliding the fixing strip 11 on the limiting strip 10, adjusting the relative distance of the fixing strip 11 so that the relative distance is the same as the width of the glass curtain wall column 5, and performing precise positioning;

[0057] S6: Install the glass curtain wall columns 5 on the curved aluminum plate 4 according to the relative distance of the fixing strips 11 .

[0058] The principle and beneficial effects of the above technical solution:

[0059] The sliding frame 8 is slidably set on the curved main bone 3, and after selecting an installation position, the glass curtain wall column 5 is installed. After the installation is completed, the fixing strip 11 is rotated away from the curved aluminum plate 4, and the sliding frame 8 is slid again, the next installation position is selected, and then the installation of the glass curtain wall column 5 is repeated; compared with setting the sliding frame 8 on the curved aluminum plate 4, the advantage of the sliding frame 8 being slidably set on the curved main bone 3 is that the installation sequence can be selected, and it can be installed from one side of the curved aluminum plate 4 to the other side. Since the fixing strip 11 can be rotated through the rotating shaft, after the middle glass curtain wall column 5 is installed, the fixing strip 11 is rotated away from the curved aluminum plate 4, and the next installation position is selected through the sliding frame 8, so it can also be installed from the center of the curved aluminum plate 4 to both sides.

[0060] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
