Description

Technical Field

[0001] This invention relates to the field of building engineering, and more specifically to the field of aluminum panel curtain wall installation. Background Technology

[0002] In recent years, with the continuous improvement of material and cultural living standards, people are paying more and more attention to the overall aesthetics of buildings while focusing on their functional use. As a result, curtain wall decoration technology has been widely promoted and applied. Currently, whether it is a new building or an old renovation project, aluminum single-panel curtain walls are widely used for many facades due to their advantages such as light weight, good rigidity, high strength, good durability and corrosion resistance, and ease of cleaning and maintenance.

[0003] The existing installation method involves completing the keel construction and obtaining concealed acceptance from all parties. After the aluminum panels arrive on site, one person manually fixes the panels while another drills holes and installs screws. This method is prone to significant installation errors, uneven seams, and substandard flatness. Furthermore, manual positioning during drilling inevitably causes panel displacement, affecting the overall installation effect. By inventing a pre-positioning control method, the construction efficiency and post-installation aesthetic quality of aluminum panels are improved, thereby reducing labor intensity, shortening the construction period, and saving production costs.

[0004] In addition, due to the long distance of the secondary keel, the spacing between adjacent secondary keels cannot be well guaranteed, and there is a lack of a spacing measurement and comparison device to facilitate the staff to observe the changes in the spacing of the secondary keels. Summary of the Invention

[0005] One objective of this invention is to provide a positioning pre-control component to ensure the installation accuracy of the keel structure, improve construction efficiency, and save production costs.

[0006] To achieve the above objectives, a positioning pre-control component is used for the pre-control installation of aluminum plates and keel structures. The aluminum plates are fixed on the keel structure, which includes multiple main keels and multiple secondary keels. The extension direction of the main keels is set to the Z-axis direction, and the extension direction of the secondary keels is set to the Y-axis direction. The Z-axis direction and the Y-axis direction are orthogonal to each other and both orthogonal to the X-axis direction.

[0007] The component includes a positioning fixture and a clamp. The positioning fixture includes a four-sided structure, comprising a first side and a second side extending along the Y-axis, the first side and the second side being used to abut against the inner edge of the secondary keel; the clamp is used to fix the positioning fixture onto the secondary keel, the clamp including a first fixing bar, a second fixing bar, a first connecting portion and a second connecting portion; the first connecting portion and the second connecting portion are respectively located on both sides of the secondary keel along the X-axis, used to clamp the first fixing bar and the second fixing bar in the Z-axis direction, the first fixing bar and the second fixing bar extending along the X-axis direction, and together applying a clamping force along the Z-axis direction to the secondary keel and the first side or the second side.

[0008] In one or more embodiments, the first connecting part is a shaft, the second connecting part is a movable bolt, and the shaft and the movable bolt pass through the first fixing strip and the second fixing strip in sequence and are locked by a nut.

[0009] In one or more embodiments, the first fixing strip includes a first screw hole and a groove, the groove including an opening, the second fixing strip includes a pair of second screw holes, one of the first screw hole and the second screw hole being symmetrically distributed to allow the shaft portion to pass through, the groove being symmetrically distributed with the other second screw hole to allow the movable bolt to pass through, and the opening being used for loading and unloading the movable bolt.

[0010] In one or more embodiments, the clamp further includes a handle rotatably mounted on the movable bolt and locked by a nut along the Z-axis.

[0011] In one or more embodiments, the first fixing strip includes a pair of first screw holes, and the second fixing strip includes a pair of second screw holes, the pair of first screw holes and the pair of second screw holes being symmetrically distributed to allow the shaft portion and the movable bolt to pass through.

[0012] In one or more embodiments, the four-sided structure of the positioning fixture is formed by welding angle steel.

[0013] In one or more embodiments, the quadrilateral structure further includes a third side and a fourth side extending along the Z-axis direction, the inner side length of the third side and the fourth side being equal to the difference between the inner side length defined by the inner edges of two adjacent secondary keels and twice the thickness of the angle steel and the reserved gap.

[0014] In one or more embodiments, the reserved gap is 5 mm.

[0015] Another object of the present invention is to provide a method for pre-controlling the positioning of aluminum panel curtain walls, comprising the following steps:

[0016] Install the main keel; install the secondary keels sequentially along the Z-axis.

[0017] After each two adjacent secondary keels are installed, the above positioning fixture is placed between the two adjacent secondary keels, and the positioning fixture is pushed along the Y-axis to check the spacing error between the two adjacent secondary keels.

[0018] Fix the main keel and the secondary keel, place the positioning fixture between any two adjacent secondary keels again, and fix it with the above-mentioned clamp, so that the positioning fixture provides a supporting force for the secondary keel along the Z-axis direction;

[0019] Pre-drill holes on the secondary keel according to the positions where the aluminum plate will be installed.

[0020] In one or more embodiments, two clamps are used at any opposite corner of the positioning fixture to fix the positioning fixture to the adjacent secondary keel.

[0021] The aforementioned positioning and pre-control components, with their positioning fixtures located between adjacent secondary keels, can effectively reduce the spacing error between the two secondary keels, ensuring the installation accuracy of the keel structure. Furthermore, the specially designed clamping structure fixes the positioning fixtures onto the keel structure, providing stable support and facilitating subsequent operations such as pre-drilling on the secondary keels. The aluminum panels are then fitted with these pre-drilled holes, allowing one person to complete the positioning and drilling of the aluminum panel installation holes and the entire aluminum panel installation process. The pre-drilled aluminum panels are installed more smoothly with even joints, effectively improving construction efficiency. Attached Figure Description

[0052] The present invention will be further described below with reference to specific embodiments and accompanying drawings. More details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can obviously be implemented in many other ways different from those described herein. Those skilled in the art can make similar extensions and derivations based on actual application situations without departing from the spirit of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.

[0053] It should be noted that these and other accompanying drawings are merely examples and are not drawn to scale, and should not be construed as limiting the scope of protection of the present invention.

[0054] Reference Figure 1 As shown, the positioning pre-control component is used for the pre-control installation of the aluminum plate (not shown) and the keel structure 10. The aluminum plate is fixed to the keel structure 10, which includes multiple main keels 101 and multiple secondary keels 102. The extension direction of the main keels 101 is set to the Z-axis direction, and the extension direction of the secondary keels 102 is set to the Y-axis direction. The Z-axis direction and the Y-axis direction are orthogonal to each other and both are orthogonal to the X-axis direction. The back wall used to set the keel structure extends along the ZOY plane.

[0055] The positioning pre-control assembly includes a positioning fixture 20 and a clamp 30. The positioning fixture 20 includes a four-sided structure, comprising a first side 201 and a second side 202 extending along the Y-axis direction. The first side 201 and the second side 202 are used to abut against the inner edge 1028 of the secondary keel 102. Specifically... Figure 1 As shown, the outer edges of the first side 201 and the second side 202 abut against the inner edge 1028 of the secondary keel 102.

[0056] It should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.

[0057] Furthermore, this application uses specific terms to describe embodiments of the application. For example, "an embodiment," "one embodiment," and / or "some embodiments" refer to a particular feature, structure, or characteristic related to at least one embodiment of the application. Therefore, it should be emphasized and noted that "an embodiment," "one embodiment," or "an alternative embodiment" mentioned twice or more in different locations in this specification do not necessarily refer to the same embodiment. In addition, certain features, structures, or characteristics in one or more embodiments of the application can be appropriately combined.

[0058] In one or more embodiments, the four-sided structure of the positioning fixture is formed by welding angle steel. If L50 angle steel is selected, its strength is verified on-site by hammering to ensure it fully meets the requirements for fixture fabrication. A cutting machine is used for cutting, ensuring the cutting blade's material input surface is aligned with the cutting line during the cutting process. If the center of the cutting blade is aligned with the cutting line, the actual cut size will be smaller than the marked size. The angle steel is kept perpendicular to the cutting blade, with the material input surface aligned with the cutting line, and the cutting is performed slowly. After cutting, burrs on the cut surface are ground with an angle grinder to make the cut surface smooth. This method is used to cut and grind the four angle steel sides of the four-sided structure separately for later use.

[0059] Furthermore, the four-sided structure also includes a third side 203 and a fourth side 204 extending along the Z-axis direction. The inner side length of the third side 203 and the fourth side 204 is equal to the difference between the inner side length defined by the inner edge of the two adjacent secondary keels 102 and twice the thickness of the angle steel and the reserved gap.

[0060] Preferably, the reserved gap is 5mm. It should be noted that the 5mm reserved gap does not affect the abutment of the first side 201 and the second side 202 with the inner edge 1028 of the secondary keel 102. Considering the possibility that the shape of the keel frame may be slightly irregular, a 5mm gap is reserved between the inner edge of the angle iron of the positioning fixture 20 and the secondary keel to facilitate the adjustment of the positioning fixture.

[0061] It should be noted that the reserved gap is not limited to the above embodiments. In other embodiments, the reserved gap is selected by the staff according to the actual reserved situation.

[0062] Continue to refer to Figure 1 As shown, the distance between the inner edges of two adjacent secondary keels 102 is measured along the Z-axis, and the inner side length of the positioning fixture 20 is determined based on this length. The inner side length of the positioning fixture 20, which is also the inner side length of the third side 203 and the fourth side 204, is: the distance between the two inner edges 1028 of the two adjacent secondary keels 102 minus twice the thickness of the angle steel and then minus the reserved gap.

[0063] The outer side lengths of the third side 203 and the fourth side 204 of the positioning fixture 20 are the sum of the aforementioned inner side lengths and the width of the angle steel.

[0064] Based on the inner and outer side lengths and the end, create a 45° bevel. Draw lines on the angle iron, with the shorter side of the angle iron located on the inner side. After determining the dimensions of the angle iron, cutting and grinding it, place the angle iron on a flat work platform, ensuring that all sides are on the same horizontal plane, with the shorter side closer to the inside and the longer side closer to the outside, and all sides of the angle iron facing the same direction. Then, splice the ends of the two angle iron pieces together.

[0065] Before welding, use a right-angle ruler to position both sides to ensure the splicing angle is a 90° right angle. After positioning, perform spot welding first, then re-measure the splicing angle of the two angle irons and check for warping. Repeat this process for the other triangles, splicing and spot welding them. After all four sides are spot welded, check the inner angles of the splices and the flatness of the tooling. Once everything is checked and found to be correct, perform full welding on each seam. During welding, control the input of welding heat to avoid welding deformation.

[0066] After welding is completed, the weld seam is ground to ensure there are no protrusions. The tooling welding is complete, and the positioning tooling 20 is fabricated. The completed positioning tooling 20 can be directly used for the construction of the keel structure.

[0067] For example, during the two pre-installation of the keel, the positioning fixture 20 is placed between the two secondary keels 102, and the positioning fixture 20 is slowly moved along the Y-axis. During the pushing process, the staff can use this as a distance to measure the comparison part and check the distance error between the two secondary keels 102.

[0068] The clamp 30 is used to fix the positioning fixture 20 onto the secondary keel 102. (Refer to...) Figures 4 to 8 As shown, the clamp 30 includes a first fixing bar 305, a second fixing bar 306, a first connecting portion 301, and a second connecting portion 302. The first connecting portion 301 and the second connecting portion 302 are located on both sides of the secondary keel 102 along the X-axis direction, and are used to clamp the first fixing bar 305 and the second fixing bar 306 in the Z-axis direction. The first fixing bar 305 and the second fixing bar 306 extend along the X-axis direction and together apply a clamping force along the Z-axis direction to the secondary keel 102 and the first side 201 or the second side 202.

[0069] Specifically, in one embodiment, the first connecting part 301 is a movable bolt, and the second connecting part 302 is a shaft. The shaft and the movable bolt pass through the first fixing bar 305 and the second fixing bar 306 in sequence and are locked by the nut 303. The shaft can be a fixing bolt that passes through the first fixing bar 305 and the second fixing bar 306 and is locked by the nut along the Z-axis direction; or it can be a shaft rod that is fixedly connected to the first fixing bar 305 and the second fixing bar 306.

[0070] Based on the above embodiments, referring to Figure 5 and Figure 6 As shown, the first fixing strip 305 includes a first screw hole 3051 and a groove 3052, the groove 3052 including an opening. The second fixing strip 306 includes a pair of second screw holes 3061, one of the first screw holes 3051 and the other screw hole 3061 being symmetrically distributed to allow the shaft portion to pass through. The groove 3052 is symmetrically distributed with the other second screw hole 3061 to allow the movable bolt to pass through, and the opening of the groove 3052 is used for loading and unloading the movable bolt.

[0071] When opening the clamp, remove the movable bolt from the opening of the groove 3052, separating the movable bolt from the first fixing strip 305. At this time, the first fixing strip 305 and the second fixing strip 306 also separate from each other. When closing the clamp, insert the movable bolt into the groove 3052 from the opening of the groove 3052, with the groove 3052 on the side near the secondary keel 102. The movable bolt is locked along the Z-axis by the nut 303, thereby completing the fixing of the first fixing strip 305 and the second fixing strip 306.

[0072] In one or more embodiments, the clamp 30 further includes a handle 304, which is rotatably mounted on the movable bolt and locked by a nut along the Z-axis. The handle 304 is used to apply tension to the movable bolt. When operating the movable bolt, the operator can directly pull the handle 304 to remove the movable bolt from the opening of the groove 3052, which is labor-saving and convenient. When the first fixing bar 305 and the second fixing bar 306 are engaged, the handle is rotated to the X-axis direction to avoid affecting subsequent construction work.

[0073] Embodiments of the first fixing bar 305 and the second fixing bar 306 include, but are not limited to, the methods described above. In another embodiment, to enhance the firmness of the clamping force, the first fixing bar 305 includes a pair of first screw holes, and the second fixing bar 306 includes a pair of second screw holes, the pair of first screw holes and the pair of second screw holes being symmetrically distributed to allow the shaft and the movable bolt to pass through. The shaft and the movable bolt are respectively locked by upper and lower nuts, thereby firmly clamping the secondary keel 102 and the first side 201 or the second side 202 in the fixture.

[0074] The fixture is made as follows: holes are made in the middle of both ends of a flat iron with a length of 150mm, 20mm from the edge. These holes are the second screw holes 3061, with a diameter of 12-14mm, thus completing the making of the second fixing strip 306.

[0075] Take a flat iron piece with a length of 150mm and make a hole with a diameter of 14mm in the middle, 20mm from the edge at one end. This hole is the first screw hole 3051. Make a groove 3052 on the side 20mm from the end at the other end. The opening width of the groove 3052 is about 14mm and the length is about 32mm, thus completing the production of the first fixing strip 305.

[0076] Take a flat iron piece with a length of 180mm and make a hole with a diameter of 14mm in the middle, 20mm from the end of one end. Make a small arc downwards and backwards from the opening, with a chord length of 50mm and a chord spacing of 15mm. Keep the two ends of the arc flush with the flat iron piece to complete the handle 304. The arc shape allows for easier application of force to the first connecting part.

[0077] It should be noted that the above dimensions should not constitute a limitation of this disclosure. The specific dimensions of the fixture shall be determined by the operator with reference to the specific working environment.

[0078] Reference Figure 4 As shown, when assembling the fixture, the two holes of the first fixing strip 305 and the second fixing strip 306 with equal distances from the edge are connected with fixing bolts, and the nuts 303 are tightened to ensure that the length of the screw of the first fixing strip 305 and the second fixing strip 306 is slightly longer than the sum of the thickness of the angle steel and the thickness of the keel by about 5mm, so as to form the second connecting part 302.

[0079] Along the other end of the X-axis, the movable screw is connected by passing through the second fixing bar 306 and the clamping handle 304 to form the first connecting part 301. The movable screw should be as long as possible to provide sufficient leeway for the installation process, and can be adjusted during subsequent use, but it should not exceed the handle by too much distance to avoid wasting materials and affecting subsequent construction and installation.

[0080] The following is combined Figure 7 and Figure 8 This section introduces the usage of the clamp, taking the example of using the clamp to fix the first side 201 and the secondary keel 102. The installation position is as follows: Figure 1 Point A is shown. In one embodiment, the secondary keel 102 and the positioning fixture are both made of L50 angle steel of the same specification, and the angle steel is L-shaped. The wall 5 is located on the ZOY plane, the secondary keel 102 extends along the Y-axis, and the first connector 301 and the second connector 302 extend along the Z-axis.

[0081] When the clamp is opened, the first connector 301 is disengaged from the first fixing strip 305. Then, the opened clamp is wrapped around the secondary keel 102 and the first side 201. The secondary keel 102 and the first side 201 of the clamp are tightened in four directions by the movable bolt in the groove 3052, the shaft passing through the first screw hole 3051 and the second screw hole 3061, the first fixing strip 305 located above, and the second fixing strip 306 located below.

[0082] Specifically, the first connecting piece 301 and the first fixing strip 305 are respectively attached to the outer side of the secondary keel 102 and the inner edge of the first side 201. The second connecting piece 302 is pressed against the inner side of the secondary keel 102 along the X-axis direction, and the first connecting piece 301 and the first fixing strip 305 are fixed and pressed against the outer side of the secondary keel 102 along the X-axis direction, so as to simultaneously clamp the secondary keel 102 and the first side 201 in the X-axis and Z-axis directions, and fix the positioning fixture on the secondary keel.

[0083] Based on the above introduction to positioning fixtures, a method for pre-controlling the positioning of aluminum panel curtain walls can also be understood, including the following steps.

[0084] Install the main keel 101.

[0085] Install the secondary keel 102 sequentially along the Z-axis.

[0086] After each pair of adjacent secondary keels 102 are installed, the positioning fixture 20 is placed between the two adjacent secondary keels 102 and pushed along the Y-axis to check the spacing error between the two adjacent secondary keels 102.

[0087] Fix the main keel 101 and the secondary keel 102, and place the positioning fixture 20 between any two adjacent secondary keels 102 again, and fix it with the aforementioned clamp 30, so that the positioning fixture 20 provides support force for the secondary keel 102 along the Z-axis direction.

[0088] Pre-drill holes on the secondary keel 102 according to the positions where the aluminum plate will be installed (not shown in the hole location diagram).

[0089] In one or more embodiments, two clamps are used at either opposite corner of the positioning fixture to fix it to the adjacent secondary keel, thereby increasing the fastening force. The positioning fixture can also be installed at other locations on the secondary keel 102, as long as it can provide effective support.

[0090] Specifically, first install the main keel 101 located at both ends along the Y-axis.

[0091] After positioning the main keel at both ends, draw a line along the Y-axis between the two keels, and draw a line at each end of the main keel 101 along the Z-axis to control the distance between the main keel 101 and the wall surface 5. Ensure that multiple main keels 101 are installed and controlled on a single ZOY plane.

[0092] After confirming that the positions of each main keel 101 are correct, they are connected to the post-installed embedded parts. The above method can effectively improve the installation accuracy and straightness of the main keel.

[0093] After installing the main keel, perform the secondary keel positioning and layout steps along the Y-axis on the main keel 101. Install the secondary keel 102 according to the positioning lines along the Y-axis.

[0094] First, install the uppermost and lowermost secondary keel 102 along the Z-axis of the wall. The secondary keel 102 is installed on the main keel 101.

[0095] After adjusting the distance between the two secondary joists 102 and the wall 5, a line is drawn along the Z-axis between the upper and lower secondary joists 102 to control the distance between each secondary joist 102 and the wall 5.

[0096] When installing the second secondary keel 102 along the Z-axis, first, according to the layout position, use positioning clamps to fix the main keel 101 and the secondary keel 102. Then, place the positioning fixture 20 between the upper and lower secondary keels 102 and slowly push the positioning fixture 20 from one end of the secondary keel 102 to the other end along the Y-axis. During the pushing process, the staff will use this to check the spacing error between the two secondary keels 102.

[0097] After confirming that the spacing between the upper and lower secondary keels 102 and the overall spacing between the keel structure and the wall 5 are correct, welding is performed for final fixation. This process is repeated to install the other secondary keels, thus achieving the fixation of the main and secondary keels.

[0098] Next, place the positioning fixture 20 between any two adjacent secondary keels 102, check whether the first side 201 and the second side 202 of the positioning fixture 20 are aligned with the secondary keels, and fix it with the aforementioned clamp 30. At this time, the secondary keel 102 is fixed to the main keel 101, and the positioning fixture 20 plays the role of providing support along the Z-axis direction.

[0099] Pre-drill holes in the secondary keel 102 using a drill bit of the same specification as the self-tapping screw, keeping the drill bit perpendicular to the outer side of the secondary keel 102 on the ZOY plane. These pre-drilled holes align with the aluminum plate mounting holes, resolving the delays caused by the disconnect between the aluminum plate and keel structure construction, avoiding interruptions during material waiting, and allowing direct installation of the aluminum plates upon arrival, thus shortening the construction period.

[0100] Pre-drilling can also pre-position the installation location of the aluminum plate, effectively solving the problem of large deviations caused by workers holding the plate and drilling holes. This results in smooth joints and high flatness of the installed aluminum plates. It also allows one person to complete the installation, which previously required two people, effectively reducing labor costs.

[0101] In some embodiments, numbers describing the quantity of components and attributes are used. It should be understood that such numbers used in the description of embodiments are modified in some examples by the terms "approximately," "approximately," or "generally." Unless otherwise stated, "approximately," "approximately," or "generally" indicates that the numbers are allowed to vary by ±20%.

[0102] Accordingly, in some embodiments, the numerical parameters used in the specification and claims are approximate values, which may be changed depending on the characteristics required by individual embodiments. In some embodiments, the numerical parameters should take into account a specified number of significant digits and employ a general method of digit preservation. Although the numerical ranges and parameters used to confirm their breadth of application in some embodiments of this application are approximate values, in specific embodiments, such values ​​are set as precisely as feasible.

[0103] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0104] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of the present invention.

[0105] For example, the materials for positioning fixtures and clamps can be selected according to the specific construction scenario, and positioning fixtures are not limited to being welded from angle steel; furthermore, the reserved gap between the positioning fixtures and the secondary keel can be selected by the staff according to the actual working conditions.

[0106] Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention's technical solution shall fall within the protection scope defined by the claims of the present invention.
