Description

Technical Field

[0001] This invention relates to the field of building curtain wall installation technology, specifically to a curtain wall column connection structure and construction method with directional adjustment and conical surface centering functions. Background Technology

[0002] Building curtain walls typically consist of mullions, beams, panels, and connecting components. Among these, the curtain wall mullions, as the main vertical load-bearing components, are responsible for bearing the wind load, self-weight, and other external forces transmitted by the curtain wall panels, and transferring the load to the main structure. The installation quality of the curtain wall mullions directly affects the overall flatness, verticality, connection reliability, and subsequent panel installation accuracy of the curtain wall.

[0003] In actual construction, curtain wall mullions typically need to be connected to the civil engineering walls, embedded parts, or main structure via connectors. Due to errors in civil engineering construction, deviations in the position of embedded parts, deviations in the flatness of the wall surface, and errors in on-site measurement, the position of curtain wall mullions usually needs to be adjusted during installation. Existing connection structures mostly use elongated holes with bolts to achieve position adjustment.

[0004] For example, Chinese patent CN101949186A discloses an installation and adjustment structure for a building curtain wall column and the main building structure. It discloses that the installation connection between the curtain wall column and the main building structure is achieved through connecting corner pieces, embedded plates, and fasteners, making column installation and adjustment more convenient. This type of structure can improve the inconvenience of traditional welding installation to some extent, but its adjustment method mainly relies on screw holes, slotted holes, or fasteners. During column position adjustment, it is still necessary to repeatedly loosen the fasteners, move the column, measure and correct, and then re-tighten. Furthermore, front-to-back distance adjustment and left-to-right position adjustment easily rely on the same connecting component, and the adjustments in the two directions affect each other; secondary positional shifts may also occur during the tightening process.

[0005] Chinese patent CN217461101U discloses a curtain wall column connection structure, which includes embedded parts, adapters, columns, and sleeves. The upper and lower ends of the sleeves are respectively fitted into two adjacent columns. The adapter has a horizontal elongated hole on its side, allowing the columns to be adjusted inward and outward through the elongated hole. This structure can accommodate construction errors to a certain extent and connect adjacent columns through the sleeves. However, the adjustment of this type of structure still mainly relies on the sliding of bolts in the elongated holes, lacking a structure that can stably support the columns and provide clear adjustment levels. At the same time, the constraint between the upper and lower columns is mainly achieved through the insertion of the sleeves, and it cannot actively correct the axial deviation of the upper and lower column sections through the guiding effect of the conical surface during the segmented hoisting and docking process.

[0006] Therefore, the existing curtain wall mullion connection structure still has the following shortcomings: First, the adjustment of the front and rear distance of the column mainly relies on the sliding of the bolt in the elongated hole. Construction workers need to repeatedly loosen the bolt, move the column, measure the distance and re-tighten it, which is cumbersome. In addition, the column is prone to secondary displacement during the tightening process. Secondly, the front-to-back distance adjustment and the left-to-right centering adjustment often rely on the same set of bolt holes or connecting components. The adjustments in the two directions affect each other, which can easily lead to the left and right positions shifting after the front-to-back adjustment is completed, or the front-to-back distance changing again after the left and right correction, causing construction workers to need to make multiple corrections. Third, after the column adjustment is completed, if the locking points are not arranged properly, the connection position may rotate slightly or loosen under long-term wind load, vibration or temperature deformation, which will affect the reliability of the curtain wall column connection. Fourth, when the curtain wall mullions are large and need to be installed in sections, adjacent sections are usually connected by sleeves, connecting plates, or bolts. Since each section may have independent positional and vertical deviations during installation, misalignment, axial offset, or assembly stress can easily occur when the upper and lower sections are joined, affecting the accuracy of subsequent curtain wall panel installation.

[0007] Therefore, there is an urgent need for a curtain wall column connection structure and construction method that can enable rapid adjustment of front and rear distances, precise correction of left and right positions, reliable locking after adjustment, and guidance and centering when connecting adjacent columns. Summary of the Invention

[0008] The purpose of this invention is to provide a curtain wall column connection structure with directional adjustment and conical centering functions, so as to solve the problems mentioned in the background art of mutual interference between front-to-back distance adjustment and left-to-right centering adjustment, low adjustment efficiency, insufficient locking reliability, and easy axial deviation when connecting upper and lower segmented columns.

[0009] To achieve the above objectives, the present invention provides a curtain wall column connection structure with directional adjustment and conical surface centering functions, comprising: a base plate, wherein mounting holes are provided on both the upper and lower parts of one side of the base plate; two side plates connected to one side of the base plate; a column body disposed between the two side plates, wherein an upper fitting mechanism is connected to the upper end of the column body, a lower fitting mechanism is connected to the lower end of the column body, mounting blocks are respectively connected to both sides of the column body, and a placement block is connected below the mounting blocks; and a support and adjustment mechanism, wherein two sets of support and adjustment mechanisms are respectively disposed on the opposite inner sides of the two side plates, the support and adjustment mechanism including a support plate, the support plate being fixed to the side plate, the upper end surface of the support plate being wavy, and multiple grooves being formed by the troughs of the wavy shape, the multiple grooves being arranged sequentially along the front-to-back adjustment direction of the column body approaching or away from the base plate, and the lower end of the placement block being provided with a wavy support surface that mates with the upper end surface of the support plate. This allows the placement blocks to fall into different grooves, thus changing the front-to-back distance of the column body relative to the base plate; a centering adjustment mechanism, with two sets of centering adjustment mechanisms respectively set on the two side plates and located on both sides of the column body, the centering adjustment mechanism includes a top screw threaded to the side plate and a top block connected to the inner end of the top screw, the top block abutting against the side of the column body; a locking mechanism, which is set between the side plate and the column body, is used to lock and fix the column body between the two side plates; wherein, the upper fitting mechanism has a conical fitting hole, and the lower fitting mechanism has a conical insertion block that fits into the conical fitting hole, so that when two adjacent upper and lower column body sections are joined, the conical surface fit is used for guiding and centering; the front-to-back adjustment direction of the placement adjustment mechanism and the left-to-right adjustment direction of the centering adjustment mechanism intersect each other, so that the front-to-back distance adjustment of the column body and the left-to-right centering adjustment are independent of each other.

[0010] In a preferred embodiment, a measuring scale is provided on the side plate corresponding to the positions of multiple grooves. The measuring scale is used to indicate the front-to-back distance of the column body relative to the substrate when the placement block is located in different grooves.

[0011] In a preferred embodiment, a connecting frame is connected below the mounting block. The connecting frame has a U-shaped structure, and both ends of the connecting frame are connected to the mounting block by mounting bolts. The lower end of the connecting frame is connected to the placement block.

[0012] In a preferred embodiment, each centering adjustment mechanism includes two set screws spaced apart vertically. Two threaded holes corresponding to the set screws are provided on the side plate. The two set screws are threaded into the corresponding threaded holes, and a rotating handle is connected to the outer end of the set screw.

[0013] In a preferred embodiment, the locking mechanism includes three locking screws arranged in a triangle. Connection ports are provided on both side plates and the column body at positions corresponding to the locking screws. The connection ports are elongated holes extending along the front-to-back adjustment direction of the column body. The locking screws pass through one side plate, the column body, and the other side plate in sequence, and both ends of the locking screws extend to the outer sides of the two side plates respectively.

[0014] In a preferred embodiment, both ends of the outer wall of the locking screw are threaded, and locking nuts are threaded to both sides of the outer wall of the three locking screws. The three locking nuts located on the same side abut against the outer side of the side plate on the corresponding side.

[0015] In a preferred embodiment, the upper fitting mechanism includes an upper insert block, a first mounting plate, and an upper fitting block. The lower end of the upper insert block is inserted into the upper end of the column body. The upper insert block is connected to the first mounting plate on both sides. The first mounting plate is in the shape of an inverted L-shape. One side of the two first mounting plates is connected to the column body and the upper insert block by a first connecting bolt. The upper fitting block is connected to the middle of the upper end of the upper insert block. The upper fitting block is connected to a first upper support block on one side and a second upper support block on the other side. The lower ends of the first and second upper support blocks are connected to the upper end of the upper insert block. The upper end of the upper fitting block is provided with a tapered fitting hole. The tapered fitting hole is tapered with a larger upper part and a smaller lower part.

[0016] In a preferred embodiment, the lower fitting mechanism includes a lower insert block, the upper end of which is inserted into the lower end of the column body. Two second mounting plates are connected to both sides of the lower insert block, respectively located on both sides of the column body. One side of each of the two second mounting plates is connected to the column body and the lower insert block via a second connecting bolt. A lower fitting block is connected to the lower end of the lower insert block. A first lower support block is connected to one side of the lower fitting block, and a second lower support block is connected to the other side of the lower fitting block. The upper ends of both the first and second lower support blocks are connected to the lower end of the lower insert block. A tapered insert block is connected to the lower end of the lower insert block.

[0017] In a preferred embodiment, an elastic pad is provided between the lower end of the connecting frame and the placement block.

[0018] The present invention also provides a construction method for a curtain wall column connection structure with the above-mentioned directional adjustment and conical surface centering functions, comprising the following steps: S1. The substrate is attached to the predetermined installation position of the civil engineering wall, and the substrate is fixed to the civil engineering wall by the connectors inserted in the installation holes, so that the two side plates form an installation space for accommodating the column body. S2. Hoist the column body between the two side plates and support the placement blocks on both sides of the column body on the corresponding support plates respectively; S3. According to the design distance between the column body and the civil wall, lift or move the column body so that the placement block falls into the grooves at different positions on the support plate to complete the adjustment of the front and rear distance of the column body. S4. Rotate the top screws on the two side plates, and push the side of the column body through the top block at the inner end of the top screw, so that the column body can be adjusted to be centered between the two side plates. S5. After the front and rear distances and left and right centering positions are adjusted to the correct positions, the column body is locked and fixed between the two side plates using the locking mechanism. S6. When the column body needs to be installed in sections, first fix the lower column body so that the tapered fitting hole at the upper end of the lower column body faces upward. Then hoist the upper column body so that the tapered insert at the lower end of the upper column body is inserted into the tapered fitting hole at the upper end of the lower column body. The tapered surface fit is used to guide and center the two adjacent column bodies.

[0019] Compared with the prior art, the beneficial effects of the present invention are: 1. In actual construction, there are often positional deviations in civil engineering walls, embedded parts, or main structures. Traditional adjustment methods using elongated holes and bolts require repeated loosening and tightening of bolts, moving the column, measuring the spacing, and then re-tightening. Furthermore, the column is prone to slippage when not properly tightened. This invention utilizes the wavy upper surface of the support plate to mate with the wavy support surface of the placement block, allowing the block to fall into different grooves, thus achieving front-to-back distance adjustment while the column body is supported. This structure provides clear support positions for the column body, reducing the number of repeated measurements and bolt tightening / loosening, and improving installation efficiency and adjustment stability in high-altitude or confined working environments.

[0020] 2. In existing connection structures, position adjustments in the front-to-back and left-to-right directions often rely on the same set of elongated holes, angle brackets, or bolt connectors, which can easily lead to misalignment in one direction after adjustment in the other. This invention separates the support adjustment mechanism and the centering adjustment mechanism. The support adjustment mechanism is responsible for adjusting the front-to-back distance of the column body towards or away from the base plate, while the centering adjustment mechanism, through a top screw and a top block, is responsible for the left-to-right centering adjustment of the column body between the two side plates. Since the two directions are executed by different mechanisms, construction personnel can first perform front-to-back adjustments and then left-to-right centering adjustments, achieving independent control of front-to-back and left-to-right centering adjustments and reducing mutual interference between multi-directional adjustments.

[0021] 3. During use, curtain wall columns need to withstand wind loads, panel weight, temperature deformation, and vibration. If the locking structure is unreliable, the columns may experience slight displacement or rotation. This invention incorporates a locking mechanism between the side panels and the column body. After adjusting the front-to-back distance and left-to-right centering position, the column body is locked and fixed between the two side panels. Furthermore, when the locking mechanism uses three locking screws arranged in a triangle, it can form multi-point clamping constraints, improving the torsional and offset resistance of the connection points. The connection port is designed as an elongated oval hole extending along the front-to-back adjustment direction, accommodating different front-to-back adjustment positions of the column body and avoiding on-site hole enlargement, rework, or forced installation.

[0022] 4. For tall curtain wall columns, on-site installation and connection typically require segmented hoisting. Since the upper and lower column segments are installed and adjusted independently, axial deviation, misalignment, or connection skew can easily occur during end-to-end connection. Forcing a connection using only ordinary sleeves, connecting plates, or bolts can easily generate assembly stress and affect subsequent installation of beams and curtain wall panels. This invention incorporates a tapered fitting hole in the upper fitting mechanism and a tapered insert block in the lower fitting mechanism. When two adjacent column segments are joined, the tapered insert block is inserted into the tapered fitting hole, and the tapered surface provides a guiding effect, gradually aligning the upper and lower column segments. This reduces the difficulty of manual hole alignment and forced correction, improving the efficiency and axial consistency of segmented column connection.

[0023] 5. The various mechanisms of this invention can work synergistically according to the actual construction process, improving the overall installation quality and long-term connection reliability. During construction, the column installation foundation is first formed by the base plate and side plates. Then, the column body is adjusted in the front-to-back distance by the support and adjustment mechanism, followed by left-to-right centering adjustment by the centering adjustment mechanism. Once the front-to-back distance and left-to-right position meet the requirements, the adjustment result is fixed by the locking mechanism. When the column needs to be installed in sections, the upper and lower cooperation mechanisms are used to guide and center the upper and lower sections. The various mechanisms of this invention form a complete construction system of "support and positioning, directional adjustment, locking and fixing, and segmented centering," which can effectively reduce problems such as repeated on-site correction, temporary shim compensation, hole enlargement rework, and forced docking. It is particularly suitable for curtain wall construction scenarios with large civil engineering deviations, segmented column installation, and limited space for high-altitude operations.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention. Example

[0027] like Figures 1 to 8 As shown, the curtain wall column connection structure with directional adjustment and conical centering functions according to a preferred embodiment of the present invention includes: a base plate 1, side plates 3, a column body 7, a support and adjustment mechanism, a centering adjustment mechanism, and a locking mechanism. Mounting holes 2 are provided on both the upper and lower parts of one side of the base plate 1. During construction, expansion bolts, chemical anchors, or other connectors can be passed through the mounting holes 2 to fix the base plate 1 to a predetermined position in the civil wall or main structure. Two side plates 3 are connected to one side of the base plate 1. The two side plates 3 can be welded to the base plate 1, integrally formed with the base plate 1, or connected by fasteners. An installation space for accommodating the column body 7 is formed between the two side plates 3.

[0028] The column body 7 is located between two side plates 3. The upper end of the column body 7 is connected to an upper fitting mechanism, and the lower end of the column body 7 is connected to a lower fitting mechanism. Mounting blocks 8 are connected to both sides of the column body 7, and a placement block 11 is connected below the mounting block 8. The placement block 11 is used to cooperate with the support and adjustment mechanism to adjust the front and rear distance of the column body 7.

[0029] Two sets of support and adjustment mechanisms are respectively set on the inner sides of the two side plates 3. Each set of support and adjustment mechanisms includes a support plate 4, which is fixed on the side plate 3. The upper end surface of the support plate 4 is wavy, and the troughs of the wavy shape form multiple grooves 5. The grooves 5 are arranged sequentially along the front-to-back adjustment direction of the column body 7, moving closer to or further away from the base plate 1. The lower end of the placement block 11 is provided with a wavy support surface that matches the upper end surface of the support plate 4, so that the placement block 11 can fall into different grooves 5 to change the front-to-back distance of the column body 7 relative to the base plate 1. When adjusting the front-to-back distance, the construction personnel can lift or move the column body 7 to make the placement block 11 leave the current groove 5 and fall into another groove 5. When the placement block 11 falls into different grooves 5, the front-to-back distance of the column body 7 relative to the base plate 1 changes, thereby realizing the step-by-step adjustment of the front-to-back position of the column body 7. Since the placement block 11 is supported by the support plate 4, the column body 7 has a clear support position during the adjustment process, which helps to improve the stability of the adjustment.

[0030] Measuring scales 6 are provided on the side plate 3 at the positions corresponding to multiple grooves 5. The measuring scales 6 are used to indicate the front-to-back distance of the column body 7 relative to the base plate 1 when the placement block 11 is located in different grooves 5. Construction personnel can quickly select the corresponding groove 5 according to the design spacing and measuring scales 6, reducing repeated on-site measurements.

[0031] A connecting frame 9, which has a U-shaped structure, is connected to the mounting block 8 at its lower end via mounting bolts 10. The lower end of the connecting frame 9 is connected to the placement block 11. An elastic washer 12 is provided between the lower end of the connecting frame 9 and the placement block 11. The elastic washer 12 allows the placement block 11 to have a certain vertical floating amount relative to the connecting frame 9, enabling the wavy support surface of the placement block 11 to better conform to the upper surface of the tray 4. Simultaneously, after the locking mechanism is tightened, the elastic washer 12 provides elastic pre-tightening, reducing the risk of loosening due to vibration.

[0032] Two sets of centering adjustment mechanisms are respectively installed on the two side plates 3, located on both sides of the column body 7. Each set of centering adjustment mechanisms includes two vertically spaced top screw rods 14. Two threaded holes 13 are provided on the side plates 3, corresponding one-to-one with the top screw rods 14. The two top screw rods 14 are threaded into the corresponding threaded holes 13. A rotating handle is connected to the outer end of each top screw rod 14, and a top block 15 is connected between the two side plates 3. The top block 15 abuts against the side of the column body 7. When left-right centering adjustment of the column body 7 is required, the operator rotates the top screw rod 14, causing it to move inward or outward relative to the side plate 3. The top block 15 at the inner end of the top screw rod 14 pushes against the side of the column body 7, thereby allowing the column body 7 to move left and right between the two side plates 3. Because centering adjustment mechanisms are provided on both sides, the operator can precisely center the column body 7 by rotating one side forward and the other side backward.

[0033] The forward and backward adjustment direction of the support adjustment mechanism intersects with the left and right adjustment direction of the centering adjustment mechanism, making the forward and backward distance adjustment and the left and right centering adjustment of the column body 7 independent. Specifically, the support adjustment mechanism uses the placement block 11 to cooperate with different grooves 5 to adjust the column body 7 closer to or further away from the base plate 1, while the centering adjustment mechanism uses the top screw 14 and the top block 15 to adjust the column body 7 left and right between the two side plates 3. Both mechanisms perform adjustment functions in different directions, reducing the problem of mutual interference between the two adjustments during on-site construction.

[0034] A locking mechanism is installed between the side plate 3 and the column body 7 to lock the column body 7 between the two side plates 3. The locking mechanism includes three locking screws 17, which are arranged in a triangle to improve the torsional and offset resistance of the connection position. Connection ports 16 are provided on both side plates 3 and the column body 7 at positions corresponding to the locking screws 17. The connection ports 16 are elongated holes extending along the front-back adjustment direction of the column body 7. The locking screws 17 pass sequentially through one side plate 3, the column body 7, and the other side plate 3, with both ends extending to the outer sides of the two side plates 3. Both ends of the outer wall of the locking screws 17 are threaded, and locking nuts 18 are threaded to both sides of the outer wall of each of the three locking screws 17. The three locking nuts 18 located on the same side abut against the outer surface of the corresponding side plate 3.

[0035] The upper fitting mechanism includes an upper insertion block 19, a first mounting plate 20, and an upper fitting block 22. The lower end of the upper insertion block 19 is inserted into the upper end of the column body 7. The upper insertion block 19 is connected to the first mounting plate 20 on both sides. The first mounting plate 20 is in the shape of an inverted L-shape. One side of the two first mounting plates 20 is connected to the column body 7 and the upper insertion block 19 by a first connecting bolt 21. The upper fitting block 22 is connected to the middle of the upper end of the upper insertion block 19. The upper fitting block 22 is connected to the first upper support block 23 on one side and to the second upper support block 24 on the other side. The lower ends of the first upper support block 23 and the second upper support block 24 are connected to the upper end of the upper insertion block 19. The upper end of the upper fitting block 22 is provided with a tapered fitting hole 32. The tapered fitting hole 32 is tapered with a larger upper end and a smaller lower end.

[0036] The lower fitting mechanism includes a lower insert block 25, the upper end of which is inserted into the lower end of the column body 7. A second mounting plate 26 is connected to both sides of the lower insert block 25. The two second mounting plates 26 are located on both sides of the column body 7. One side of each of the two second mounting plates 26 is connected to the column body 7 and the lower insert block 25 by a second connecting bolt 27. A lower fitting block 28 is connected to the lower end of the lower insert block 25. A first lower support block 29 is connected to one side of the lower fitting block 28. A second lower support block 30 is connected to the other side of the lower fitting block 28. The upper ends of the first lower support block 29 and the second lower support block 30 are both connected to the lower end of the lower insert block 25. A tapered insert block 31 is connected to the lower end of the lower insert block 25.

[0037] When curtain wall columns need to be installed in sections, the lower column body 7 is first fixed to the civil engineering wall using the aforementioned connecting structure, with the tapered fitting hole 32 at the upper end of the lower column body 7 facing upwards. Then, the upper column body 7 is hoisted, with the tapered insert 31 at the lower end of the upper column body 7 facing downwards and gradually inserted into the tapered fitting hole 32 at the upper end of the lower column body 7. Because the tapered insert 31 and the tapered fitting hole 32 form a tapered surface fit, during insertion, the tapered surface guides the two adjacent column bodies 7, gradually aligning them and reducing the risk of misalignment and axial displacement between the upper and lower column bodies. Example

[0038] The present invention also provides a construction method for a curtain wall column connection structure with the above-mentioned directional adjustment and conical surface centering functions, comprising the following steps: Step S1: Attach the base plate 1 to the predetermined installation position of the civil engineering wall, and fix the base plate 1 to the civil engineering wall through the connectors inserted in the installation holes 2, so that the two side plates 3 form an installation space for accommodating the column body 7.

[0039] Step S2: Hoist the column body 7 between the two side plates 3, and make the placement blocks 11 on both sides of the column body 7 support the corresponding support plates 4 respectively.

[0040] Step S3: Based on the designed distance between the column body 7 and the civil engineering wall, lift or move the column body 7 so that the placement block 11 falls into the grooves 5 at different positions on the support plate 4 to adjust the front-to-back distance of the column body 7. Specifically, the placement block 11 connected to the lower end of the mounting block 8 rests on the wavy upper surface of the support plate 4. Each groove 5 corresponds to a step position. According to the required front-to-back distance between the column body 7 and the wall, the worker selects the corresponding groove 5 with reference to the measuring scale 6, lifts the column body 7 so that the placement block 11 is removed from the current groove 5, moves it to the target groove 5 and puts it down, realizing a quick coarse adjustment of the front-to-back distance.

[0041] Step S4: After completing the front and rear coarse adjustment, rotate the rotating handle of the centering mechanism to drive the top screw 14 to screw in or out of the threaded hole 13 in the side plate 3. The top block 15 at the inner end of the top screw 14 pushes against the side of the column body 7, so that the column body 7 can be adjusted to be centered between the two side plates 3.

[0042] Step S5: After adjusting the front-back distance and left-right centering position, the column body 7 is locked and fixed between the two side plates 3 using the locking mechanism. Specifically, three locking screws 17 arranged in a triangle are passed sequentially through the elongated oval connection port 16 on one side plate 3, the corresponding connection port 16 on the column body 7, and the elongated oval connection port 16 on the other side plate 3. Both ends of the locking screws 17 are screwed into the locking nuts 18 and tightened. The elongated oval connection port 16 allows the locking screws 17 to move freely within the front-back adjustment range to adapt to changes in the position of the column body 7.

[0043] Step S6: When the column body 7 needs to be installed in sections, each column body 7 has an upper fitting mechanism installed at its upper end and a lower fitting mechanism installed at its lower end. Taking two adjacent column sections as an example: First, fix the lower column body 7 so that the tapered fitting hole 32 at the upper end of the lower column body 7 faces upward. Then, hoist the upper column body 7 so that the tapered insert 31 at the lower end of the upper column body 7 is inserted into the tapered fitting hole 32 at the upper end of the lower column body 7. The taper of the tapered insert 31 is precisely matched with the taper of the tapered fitting hole 32, thereby guiding and centering the two adjacent column body sections 7 through the tapered surface fit.

[0044] Specifically, the small end of the conical insert 31 first enters the large end of the conical mating hole 32. Due to the guiding effect of the conical surface, even if there is a slight axial deviation between the two column bodies 7, the conical insert 31 will generate a lateral force after contacting the conical surface of the conical mating hole 32. This force guides the axis of the upper column body to gradually approach the axis of the lower column body. As the descent depth increases, the contact area of ​​the conical surface increases, and the alignment effect becomes more accurate. When the conical insert 31 is fully inserted into the conical mating hole 32 and the end faces of the two column bodies 7 are tightly fitted, the two column bodies 7 are fixedly connected by a special fixing plate and fixing bolts, reducing the assembly stress when the upper and lower column bodies are joined and improving the alignment accuracy of the upper and lower column bodies.

[0045] Using the above construction method, the column body 7 can first be adjusted in front and back distance using the support and adjustment mechanism, then adjusted in left and right centering using the centering adjustment mechanism, and finally fixed by the locking mechanism. During segmented installation, adjacent upper and lower column body segments 7 can be guided and aligned by the conical surface of the conical insert 31 engaging with the conical mating hole 32. Thus, the present invention can effectively improve the installation efficiency, position adjustment accuracy, and segmented connection reliability of curtain wall columns.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
