Description

Technical Field

[0001] This invention relates to a method for installing inclined column curved beams, and more particularly to a method and construction mechanism for segmented installation of inclined column curved beams without support frame. Background Technology

[0002] The advantages of lightweight and high strength enable steel structures to complete more complex shapes and constructions in large-span public buildings, making the buildings more beautiful and enhancing the overall image of the city. However, if it is a traditional regular steel structure, it is easier to handle during transportation and installation, and workers do not need to worry about deformation. But if the steel structure to be constructed is an irregular shape, there will be certain difficulties in the installation process.

[0003] For example, inclined column curved beam components have a large span and an irregular figure-eight structure. Both the curved beam and inclined column sections have some curvature. If the operation is not done properly, both the inclined column and curved beam sections are prone to deformation.

[0004] Conventional inclined column and curved beam components are often installed by erecting scaffolds under both the inclined column and the curved beam sections. These scaffolds support the inclined column and the curved beam section respectively until the welded areas have completely cooled and solidified before being removed. This installation method will lengthen the construction period and significantly increase the construction cost. Furthermore, because the scaffolds use multi-point contact support, the inclined column and curved beam will experience a certain degree of settlement after the scaffolds are dismantled, and this process is subject to certain uncertainties.

[0005] Therefore, this case aims to provide a segmented installation method and construction mechanism for inclined columns and curved beams without support frame, which can be installed in sections without the use of a jig and is less likely to cause excessive deformation to the inclined column when the curved beam and inclined column are matched. Summary of the Invention

[0006] This invention provides a method and mechanism for segmented installation of inclined column curved beams without support frame, which can effectively solve the above problems.

[0007] This invention is implemented as follows:

[0008] A method for segmented installation of inclined column curved beams using an unsupported formwork, comprising:

[0009] Step 1: Fix the embedded parts in the structural beams and slabs;

[0010] Step 2: Hoist the inclined column to the point where it abuts against the embedded part, and extend at least one guy rope from the center of the inclined column and fix it to the embedded part;

[0011] Step 3: Extend two sets of clamping frames from the side of the embedded part and clamp them onto the inclined column;

[0012] Step 4: Fix a node support rod at the top of the embedded part, so that the node support rod passes through the inclined column and forms a supporting arc surface at the top of the inclined column;

[0013] Step 5: Hoist the curved beam so that one end of the curved beam is placed in the supporting arc surface and the other end abuts against the exterior wall of the building. The outer support rod at the bottom of the curved beam is attached to the inclined column. Weld the two ends of the curved beam to the top of the inclined column and the exterior wall of the building respectively. Then, weld the bottom of the inclined column to the lower half of the embedded part to form a stable three-point connection.

[0014] Step 6: After the welded parts have cooled down, remove the embedded parts, guy ropes, clamping frames, node struts, and external struts to form a steel structure with a 7-shaped structure between the inclined column and the curved beam.

[0015] As a further improvement, step two also includes: taking the center line of the inclined column as a node, three guy ropes are respectively set at the midpoints of the three faces of the inclined column, and the other end of the guy ropes is fixed to the midpoint of the bottom surface of the embedded part and the vertices on both sides respectively.

[0016] As a further improvement, step three also includes: one set of clamping frames extending downward from the embedded part and clamping the lower half of the inclined column, and another set extending upward and clamping the upper half of the inclined column, with the two sets of clamping frames cooperating with the inclined column at the two lifting points of the inclined column.

[0017] As a further improvement, step four also includes: the node support rod is inserted from the side of the inclined column, penetrating the truss structure inside the inclined column, and forming a supporting arc surface on the other side of the inclined column; then, the bottom of the node support rod extends downwards to a connecting frame and is locked to the upper clamping frame; the point where the connecting frame and the node support rod cooperate is the midpoint of the node support rod.

[0018] As a further improvement, step five also includes: pressing the top surface of the inclined column and the outer surface of the curved beam against the supporting arc surface at the same time, so that both the load-bearing node and the welded node are located within the supporting arc surface, and dissipating the force to the node strut, connecting frame, and clamping frame through the supporting arc surface.

[0019] As a further improvement, step five also includes: before the curved beam is hoisted into place, the outer support rod is aligned with the inclined column. After the outer support rod and the inclined column are in place, the curved beam is hoisted into place and forms a connection with the welding point of the inclined column. The outer support rod at the center point of the curved beam pushes the inclined column outward.

[0020] This invention also provides a segmented installation construction mechanism for inclined column curved beams without support frame, comprising:

[0021] Embedded parts welded to the wall frame;

[0022] A guy rope assembly nailed to the bottom corner of the embedded part and locked to the center section of the inclined column;

[0023] Two sets of clamping frames are locked to the outside of the embedded part and respectively clamped to the outside of the inclined column;

[0024] A node support rod is locked to the top of the embedded part, passes through the inclined column and extends to the top of the inclined column. The node support rod extends downward to a connecting frame that is vertically fixed to the upper section of the clamping frame.

[0025] An outer strut is locked below the center of gravity of the curved beam, and the other end of the outer strut abuts against the inside of the inclined column.

[0026] As a further improvement, the guy rope assembly includes guy ropes nailed to the midpoint of the centerline of the three sides of the inclined column near the embedded part, and the other ends of the three guy ropes are respectively locked to the midpoint of the bottom of the embedded part and two vertices.

[0027] As a further improvement, the two sections of the clamping frame are respectively clamped to the two suspension points of the inclined column.

[0028] As a further improvement, the embedded component includes a lower embedded plate, a main beam plate locked above the lower embedded plate, and a tie rod assembly fixed to the right side of the lower embedded plate and the main beam plate and nailed to the wall frame.

[0029] The beneficial effects of this invention are:

[0030] This invention employs a segmented installation method for inclined columns and curved beams without the need for a support frame. Using a segmented hoisting approach, the inclined columns are first hoisted and secured to a clamping frame via guy ropes, then pulled inwards. Next, the curved beams are hoisted, and the inclined columns are pushed outwards via nodal struts on the curved beams. Welding is achieved at the connection points between the inclined columns and curved beams, and between the curved beams and the building structure. This method secures the inclined column and curved beam structure while preventing settlement, bending, and deformation of the weighted inclined columns. The entire construction process eliminates the need for complex support frames, and the various supporting structures work together to prevent deformation and displacement of the inclined columns and curved beams before welding and cooling. The resulting 7-shaped structure is aesthetically pleasing and resistant to deformation after use. Attached Figure Description

[0043] All embodiments of the present invention are intended to fall within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort indicate or imply the relative importance of the indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0045] In the construction process of hoisting and welding irregularly shaped steel structures, the use of jigs is a common method. The jigs provide internal and external support for the hoisted workpiece, serving as a temporary positioning and support structure. However, this requires custom-made jigs with coordinated internal and external components; otherwise, settlement and deformation can easily occur. The fabrication of jigs directly extends the construction period and increases costs. Furthermore, existing hoisting methods typically involve hoisting entire sections, but for L-shaped structures, neither curved beams nor inclined columns can achieve balance during the hoisting process, inevitably affecting the un-hoisted portion. To address these technical problems, this paper proposes the following technical solution:

[0046] In this implementation, the workpiece is hoisted as Figure 1 The inclined column and curved beam structure is a figure-7 shaped structure, and both the inclined columns and the curved beams have a certain degree of curvature.

[0047] Because this project uses segmented hoisting, there are three welding points: the weld between the inclined column and the embedded part, the weld between the inclined column and the curved beam, and the weld between the curved beam and the main building. If any of these three welding points fails before the welding cools and solidifies, it is extremely easy for the entire steel structure to collapse, causing a building accident.

[0048] Reference Figure 2 As shown, a method for segmented installation of inclined column curved beams using an unsupported formwork includes:

[0049] Step 1: Fix the embedded parts in the structural beams and slabs;

[0050] In this embodiment, in order to attach the structure and avoid causing excessive damage to the building's external walls, it is necessary to install embedded parts. Therefore, in order to install the embedded parts, firstly, a keel frame needs to be installed in the building's external walls. The keel frame is made of cement and is hidden in the wall to avoid being directly exposed to the outside, which would be unsightly. While forming a connection medium, it can also strengthen the building itself. Then, the embedded parts are locked to the keel frame. When the embedded parts are under stress, the stress can be directly transmitted and distributed to the entire building, improving the strength that the embedded parts can withstand.

[0051] Furthermore, since the embedded parts are locked onto the keel frame, they will not cause excessive damage to the main structure of the building. After the hoisting and welding process is completed, some of the embedded parts can be removed at any time and quickly moved to another hoisting point. If the embedded parts are directly connected to the main structure of the building, dozens or even hundreds of holes will be needed on the exterior of the main structure after a complete installation process. The embedded parts that cannot be removed are simply painted the same color as the wall for decoration.

[0052] After the embedded parts are fixed, hoisting can begin, proceeding to step two.

[0053] Step 2: Hoist the inclined column to the point where it abuts against the embedded part, and extend at least one guy rope from the center of the inclined column and fix it to the embedded part;

[0054] In this embodiment, the lifting cables at both ends are connected by the lifting device on the crane. First, the center of gravity of the inclined column is calculated (the center of gravity of the inclined column is generally the midpoint of the inclined column). Then, two symmetrical lifting points are found based on the center of gravity of the inclined column. The lifting cables are connected to the lifting points of the inclined column. Then, the crane is lifted to move the inclined column so that the inner side of the inclined column fits against the embedded part, thus forming a preliminary positioning. Then, one end of the guy rope is locked at the center of the inner side of the inclined column, and the other end of the guy rope is locked to the midpoint of the bottom line of the embedded part, thus forming the second step of positioning.

[0055] However, in the second step of positioning, if only one set of guy ropes is set, the top hoisting rope is prone to swaying under the action of the wind, and the guy rope with the fixed point is only the midpoint of the bottom line. Therefore, the entire inclined column is prone to swinging left and right under the action of the wind with the midpoint of the bottom line of the embedded part as the node. This not only makes the second step of positioning inaccurate, but also easily leads to the guy rope breaking.

[0056] Therefore, step two also includes: taking the center line of the inclined column as a node, setting three guy ropes at the midpoints of the three faces of the inclined column respectively. The other end of the guy ropes is fixed to the midpoint of the bottom surface of the embedded part and the vertices on both sides respectively. Specifically, the three faces are the side of the inclined column close to the embedded part and the left and right sides of this side. The midpoint of the center line of the three faces is taken on each of the three faces to establish three sets of guy ropes. The three sets of guy ropes are fixed at different nodes. With the fixation of the three fixed nodes, the entire inclined column is initially fixed, completing the second step of positioning, and providing a good positional basis for the subsequent positioning and fixing step three.

[0057] Step 3: Extend two sets of clamping frames from the side of the embedded part and clamp them onto the inclined column;

[0058] In this embodiment, because the inclined column is curved, it extends outwards, and its slope gradually increases as it extends upwards. Therefore, although the position is fixed through the second step of positioning, the three sets of guy ropes alone cannot completely hold the inclined column. The curved inclined column always tends to tilt downwards, so a final step of tying and fixing is required, namely:

[0059] First, a locking seat is installed on the side of the embedded part. The seat has two ear plates, and two sets of clamping frames are fixed on the ear plates. These are then fixed to the inclined column. Specifically, the clamping frame is an L-shaped structure. One end of the long end extends from the seat to the outer side of the inclined column, while the short end is clamped on the outer edge of the inclined column or the truss structure inside the inclined column. On one set of clamping frames, there are two sets of L-shaped structures facing each other, which can hold the entire inclined column from both sides, so that the inclined column is subjected to an inward clamping force. The upper and lower sets of clamping frames can respectively form an inward pulling force from the upper and lower halves of the inclined column. Combined with the tension of the guy rope at the center of gravity of the inclined column, three uniform tensions are formed on the inclined column, so that the inclined column, which is always bending outward, can be tightly tightened and positioned, providing a good preliminary foundation for the welding of the curved beam.

[0060] Two construction methods can be used during the installation of the clamping frame. One method is to make the part of the clamping frame that mates with the card seat a hinged structure, so that the clamping frame can be opened outward, making installation and disassembly more convenient. The other method is to first make the short end of the L-shaped structure of the clamping frame mate with the inclined column, and then fix it to the card seat of the embedded part, so as to keep the position of the clamping frame stationary.

[0061] It is important to note that the short end of the L-shaped clamping frame must be level with the inclined column during installation to ensure proper fit and thus guarantee clamping force.

[0062] In order to significantly improve the effectiveness of the clamping frame and prevent deformation of the inclined column after the clamping frame is removed, the two sets of clamping frames are positioned at the two suspension points of the inclined column. The suspension points are the relatively uniform stress-bearing ends of the inclined column, and similarly, the center of gravity is also at these points. When the tie structures at the suspension points and the center of gravity are removed, the impact on the stability of the inclined column itself is minimized.

[0063] After step three is completed, all construction steps for the inclined column are finished. The inclined column is now firmly anchored and positioned. Even if the curved beam is pressed down, the inclined column is unlikely to tilt, settle, or deform. This creates favorable conditions for the subsequent welding of the inclined column and the embedded parts. Then, the curved beam can be hoisted. During the connection between the curved beam and the inclined column, the connection only exists at the 7-shaped fold. The stability of the connection directly determines the aesthetics and stability of the entire inclined column-curved beam structure after it is formed. Therefore, before the inclined column and the curved beam are connected and before welding occurs, step four needs to be performed first.

[0064] Step 4: Fix a node support rod at the top of the embedded part, so that the node support rod passes through the inclined column and forms a supporting arc surface at the top of the inclined column;

[0065] As mentioned in the above description, the inclined column is actually a frame with an internal truss structure. There are gaps between various steel components, and the node struts utilize these gaps. During installation, they are inserted through the gaps in the truss structure and fixed to the top of the embedded part. After the node struts are fixed to the top of the embedded part, the supporting arc surface at the top of the node struts happens to be located at the top of the inclined column, and the arc surface is concave inward, which can hook the inclined column and support it together after the curved beam is in place.

[0066] Furthermore, since the node support rod is set at an angle, its installation is actually quite difficult. In this embodiment, a reverse fixing method is used to fix the angled support rod. The locking rod is driven in from the inside of the embedded part outward, so that the locking rod passes through the embedded part and connects with the node support rod. The angled fixing method makes the angled node support rod more stable and more stable when fixing the diagonal bar and curved beam.

[0067] The primary purpose of the node strut is to support the inclined column and the curved beam, and to standardize the welding points between them, so that they can limit and fix the two during welding and after welding, and wait for cooling and shaping. During the welding process, it will bear the weight of the inclined column and the curved beam. Therefore, in order to improve its support performance, step four also includes: the node strut is inserted from the side of the inclined column, penetrating the truss structure inside the inclined column, and forming a supporting arc surface on the other side of the inclined column. Then, the bottom of the node strut extends downward to a connecting frame and is locked to the upper clamping frame. The point where the connecting frame and the node strut cooperate is the midpoint of the node strut. The connecting frame connects the entire node strut with the clamping frame and the embedded parts. When the node strut is under pressure, it will be transmitted downward through the connecting frame to disperse the pressure.

[0068] After all the above construction steps are completed, step five, hoisting the curved beam, can be carried out.

[0069] Step 5: Hoist the curved beam so that one end of the curved beam is placed within the supporting arc surface, and the other end abuts against the exterior wall of the building. The outer support rod at the bottom of the curved beam is attached to the inclined column. Weld the two ends of the curved beam to the top of the inclined column and the exterior wall of the building, respectively.

[0070] When hoisting a curved beam, the center of gravity of the curved beam is calculated first, so that the crane hook is directly above the center of gravity. Then, two lifting points are calculated, and the curved beam is hoisted by connecting two slings through the hook.

[0071] When hoisting the curved beam above the inclined column, first, allow the curved beam to enter the supporting arc surface. However, at this time, do not allow the curved surface to directly overlap the inclined column, otherwise most of the weight of the curved beam will directly press on the inclined column. Since the bottom of the inclined column has not yet been welded, direct pressure may cause partial settlement and deformation of the curved structure before the bottom is fully fixed. After the curved beam enters the supporting arc surface, connect the other end of the curved beam to the building and support it directly on the building to share part of the weight of the curved beam. Only then can the curved beam be overlapped on the inclined column. Step five also includes: pressing the top surface of the inclined column and the outer surface of the curved beam against the supporting arc surface at the same time, so that the load-bearing node and the welded node are both located within the supporting arc surface. The load is distributed to the node support rod, connecting frame, and clamping frame through the supporting arc surface to relieve the pressure. At this time, part of the inclined curved beam presses on the inclined column and part presses on the node support rod, sharing the pressure of the inclined column.

[0072] However, as can be seen from the figure, the inclined column is partially tilted. If the crane force is removed directly when the initial welding is completed, it may cause the curved beam and the inclined column to slide, causing the inclined column or the curved beam to settle and deform. Therefore, step five also includes: before the curved beam is hoisted into place, the outer support rod is aligned with the inclined column. After the outer support rod and the inclined column are in place, the curved beam is hoisted into place and forms a fit with the welding point of the inclined column. The outer support rod at the center point of the curved beam pushes the inclined column outward.

[0073] During the hoisting of the inclined column, guy ropes, clamping frames, and node support rods were installed to pull the entire inclined column inward, so that the bottom of the inclined column would not tilt outward during welding and cooling. However, after the curved beam was lowered, it might slip before it was fully welded to the inclined column. Therefore, during the lowering of the curved beam, the outer support rods were used to push the inclined column outward, so that the inclined column, guy ropes, clamping frames, and node support rods would simultaneously provide an upward force to the curved beam, allowing the curved beam to maintain initial stability after the crane's tension was removed. Then, welding was started at both ends.

[0074] After the above two welding points are completed, since the entire structure is basically stable at this time and there will be no sudden increase in pressure, such as when the curved beam is lowered for installation, the inclined column can be welded to the lower half of the embedded part to completely fix the entire structure.

[0075] After the welding process is completed, a certain cooling time is required to allow the welded parts to cool and stabilize, so that all three weld points are secure. After the cooling process is completed, proceed directly to step six.

[0076] Step 6: After the welded parts have cooled down, remove the embedded parts, guy ropes, clamping frames, node struts, and external struts to form a steel structure with a 7-shaped structure between the inclined column and the curved beam.

[0077] Throughout the construction process, except for the lower half of the embedded part which needs to be welded to the bottom of the inclined column and cannot be disassembled, the other parts of the embedded part, as well as the guy rope, clamping frame, node support rod, and external support rod, can be disassembled and reused.

[0078] On-site, three or more sets of the above-mentioned components can be prepared. When the third set of components is being used, the welding process of the first set of components has been completed and the components can be disassembled. Therefore, as long as three sets of the above-mentioned components are prepared, the cycle can be completed.

[0079] Reference Figure 3-11 As shown, another embodiment of the present invention also provides a segmented installation construction mechanism for inclined column curved beam without support frame, including: an embedded part 1 welded to the wall frame; a group of guy ropes 2 nailed to the bottom corner of the embedded part 1 and locked to the center section of the inclined column; two sets of clamping frames 3 locked to the outside of the embedded part 1 and respectively clamped to the outside of the inclined column; a node support rod 4 locked to the top of the embedded part 1, passing through the inclined column and extending to the top of the inclined column, the node support rod 4 extending downward to a connecting frame 5 vertically fixed to the upper section of the clamping frame 3; and an outer support rod 6 locked below the center of gravity of the curved beam, the other end of the outer support rod 6 abutting the inside of the inclined column.

[0080] The guy rope group 2, the clamping frame 3, and the node support rod 4 are all designed to hold the inclined column in place, providing a stable condition for welding at both ends of the inclined column. The outer support rod 6 provides a stable condition for welding at both ends of the curved beam.

[0081] To improve the tie-in performance of the guy rope assembly 2, the guy rope assembly 2 includes guy ropes 21 nailed and fixed at the midpoint of the centerline of the three sides of the inclined column near the embedded part 1, and the other ends of the three guy ropes 21 are respectively locked at the midpoint of the bottom of the embedded part 1 and two vertices.

[0082] In order to improve the binding effect of the clamping frame 3, and at the same time, without damaging the inclined column, the two sections of the clamping frame 3 are respectively clamped to the two suspension points of the inclined column. The lower section of the clamping frame 3 is perpendicular to the inclined column, so that the binding performance is maximized.

[0083] In this embodiment, in order to improve the strength of the clamping frame 3, the clamping frame 3 includes a long plate 31 with a U-shaped structure and a short plate 32 connected to the long plate 31. The short plate 32 can be a square structure or an arc structure. The clamping frame 3 and the embedded part 1 can be connected by a ball joint or by screw locking.

[0084] In this embodiment, the node support rod 4 serves to cover the inclined column and the curved beam. Therefore, its stability directly determines the stability of the inclined column and the curved beam joint during the welding and cooling processes. To improve the strength of the long-distance node support rod 4 mounting base, the node support rod 4 includes a long arm 41, a supporting arc seat 42 located at the top of the long arm 41, a mounting seat 43 locked to the embedded part 1, and a reverse locking rod 44 that passes through the embedded part 1 from the inside and is threadedly connected to the inside of the long arm 41. The midpoint of the long arm 41 is supported and stabilized by the connecting frame 5, so there is no need to worry about it deforming and breaking in the middle. At the end of the long arm 41, there is a reverse locking rod 44 that locks the long arm 41 from the opposite direction, which largely prevents the long arm 41 from deforming and bending from the bottom, thereby improving the overall stability of the long arm 41.

[0085] During the connection between the outer strut 6 and the inclined column, as the height of the curved beam decreases, the outer strut 6 gets closer and closer to the inclined column. To prevent slippage between the outer strut 6 and the inclined column after connection and to avoid forcibly damaging the truss structure on the inclined column, a horizontal bar is provided on the inclined column. The outer strut 6 includes a strut 61 locked below the center of gravity of the curved beam, a receiving groove 62 opened on the inner side of the bottom of the strut 61 and inserted into the horizontal bar, and an inner nail 63 provided in the receiving groove 62 and penetrating the horizontal bar. During the descent of the strut 61, the receiving groove 62 will engage with the horizontal bar on the inclined column, and at the same time, the inner nail 63 will be inserted into the hole on the horizontal bar, so that the outer strut 6 and the inclined column are connected. At the same time, since the outer strut 6 is set at the center of gravity of the curved beam, it can support the curved beam while maintaining the stability of the inclined column itself.

[0086] As mentioned above, the embedded part 1 is divided into a removable part and a non-removable part. The specific composition of the embedded part 1 is as follows: the embedded part 1 includes a lower embedded plate 11, a main beam plate 12 locked above the lower embedded plate 11, and a tie rod group 13 fixed to the right side of the lower embedded plate 11 and the main beam plate 12 and nailed to the wall frame. The tie rod group 13 can be removed, while the lower embedded plate 11 and the main beam plate 12 are directly left on the exterior wall of the building and can be used as decoration by painting.

[0087] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
