Description

Technical Field

[0001] The invention relates to the technical field of building construction engineering, in particular to a lantern-shaped roof ridge frame and a construction method thereof. Background Art

[0002] In the construction of arched roof steel structures, especially in the construction process of roofs with larger spans, due to the large span of the roof main beams, the roof main beams are generally constructed in sections in actual construction. Each main beam section requires a support frame for support. The larger the span of the main beam section, the more support frames are required. Therefore, for roof steel structures with larger spans, the number of support frames is larger, which increases the construction cost of the roof steel structure construction.

[0003] Moreover, the lifting of each main beam segment needs to be carried out strictly according to the construction schedule. The corresponding segment can only be lifted when it needs to be installed in segments. The segments after lifting need to be set at the corresponding positions through support frames, and then the adjacent segments are welded and fixed. At this time, the support frame set under the main beam segment is used to support the main body of the main beam segment and is basically not set at the welding interface of the main beam segment. Therefore, in actual welding operations, the supporting force of the docking interface ends of adjacent main beam segments is insufficient, welding is difficult, and the overall construction difficulty is increased. Summary of the Invention

[0004] In response to the deficiencies in the above-mentioned background technology, the present invention proposes a lantern-shaped ridge frame and a construction method thereof. The ridge main beam of the present invention is completed by welding multiple segments, which can form a stable lantern-shaped structure. In addition, each segment of the main beam can be carried out on the ground or in the factory, which not only has a fast construction speed but also low cost. During the construction process, the support frame arranged at the butt joint end of each main beam segment can provide better support for the butt joint ends of the main beam segments, thereby making it easier to connect the main beam segments.

[0005] The technical solution of the present invention is achieved as follows:

[0006] A lantern-shaped ridge frame includes a concrete base set on the ground, an embedded steel frame with shear studs fixed inside the concrete base, a support steel plate on top of the embedded steel frame, a ridge main beam set between symmetrical concrete bases, and two ends of the ridge main beam fixed to the support steel plates of the corresponding concrete bases;

[0007] The ridge main beam includes main beam segment I, main beam segment II and main beam segment III. Main beam segment I and main beam segment III are respectively fixed on both sides of main beam segment II and are symmetrically arranged about main beam segment II, forming a "𠘨"-shaped structure.

[0008] Furthermore, the main beam segment I and the main beam segment III both include an arc-shaped beam I and a V-shaped support column. The V-shaped support column is arranged on the outer arc side of the arc-shaped beam I, and the two ends of the V-shaped support column face the outer arc side of the arc-shaped beam I. The outer arc side of the arc-shaped beam I is provided with two support legs corresponding to the two ends of the V-shaped support column respectively. The two ends of the V-shaped support column are respectively connected to the corresponding support legs through connecting parts, and the corner ends of the V-shaped support column are fixedly connected to the support steel plate on the concrete base.

[0009] Furthermore, the V-shaped support column includes a hook-shaped support rod and a connecting straight rod, the connecting straight rod is coaxially arranged with the short rod of the hook-shaped support rod, and is connected to one end of the short rod of the hook-shaped support rod through a connecting piece.

[0010] Furthermore, a swing column is hinged on the arc beam I. The swing column is located on the side of the hook-shaped support rod away from the connecting straight rod and close to one end of the arc beam I. The bottom end of the swing column is hinged on the concrete frame around the main ridge beam.

[0011] Furthermore, the connecting member includes a reinforcing rib plate and a wing plate arranged on the side wall of the corresponding rod member, and the reinforcing rib plate is connected to the corresponding wing plate through bolts.

[0012] Furthermore, the main beam segment II includes two mutually symmetrical curved beams II and two mutually symmetrical V-shaped connecting rods. The two curved beams II are distributed in an "eight" shape and correspond to the curved beam I of the main beam segment I and the curved beam I of the main beam segment III, respectively. The curved beam II is fixedly connected to the corresponding curved beam I and is located on the extended arc line of the corresponding curved beam I.

[0013] The two V-shaped connecting rods are located between the two arc-shaped beams II and correspond to the two arc-shaped beams II respectively. The two ends of the V-shaped connecting rod are fixed on one side of the outer arc of the corresponding arc-shaped beam II. The corner ends of the two V-shaped connecting rods are provided with welding planes for welding.

[0014] Furthermore, a reinforcement rod is connected between the top ends of the two arc-shaped beams II.

[0015] A construction method for the lantern-shaped ridge frame as described in the above technical solution comprises the following construction steps:

[0016] S1: Complete the ground assembly of the V-shaped support column;

[0017] S2: Complete the ground assembly of main beam segment I and main beam segment III;

[0018] S3: Complete the assembly of main beam segment II on the ground;

[0019] S4: Remove the reinforcing ribs on the sides of the outriggers, hook-shaped support rods, and straight rods;

[0020] S5: Use the lifting equipment to move the main beam segment I to the top of the preset concrete base, fix the corresponding V-shaped support column on the corresponding concrete base and install the corresponding swing column on the corresponding concrete frame, and then pull the guy ropes on both sides of the corresponding curved beam I;

[0021] S6: Use the lifting equipment to move the main beam segment III to the top of the preset concrete foundation, fix the corresponding V-shaped support column on the corresponding concrete foundation and install the corresponding swing column on the corresponding concrete frame. Then, the main beam segment III is arranged symmetrically with the main beam segment I and guy ropes are stretched on both sides of the curved beam I of the main beam segment III.

[0022] S7: A support frame is provided on the side where the main beam segment I and the main beam segment III are close to each other, and the support frame is provided below the end where the main beam segment I and the main beam segment III are close to each other;

[0023] S8: If it is the first time to construct the ridge beam, two groups of the main beam segments I and III need to be set up during construction, and purlins need to be fixed between two adjacent main beam segments I and adjacent main beam segments III, and then step S9 can be performed. If it is not the first time to construct the ridge beam, purlins need to be fixed between the main beam segment I constructed later and the adjacent main beam segment I, and between the main beam segment III constructed later and the adjacent main beam segment III, and then step S9 can be performed.

[0024] S9: Use the lifting equipment to lift the main beam segment II to between the main beam segment I and the main beam segment III, and make the two ends of the main beam segment II be located on the support frames on the corresponding side respectively;

[0025] S10: The construction workers weld the corresponding curved beams I and II using a hanging basket or lifting equipment. After welding, the support frame is removed to complete the construction of the ridge beam.

[0026] S11: Fix the purlins between adjacent main beam sections II;

[0027] S12: Repeat steps S1-S11 according to the design requirements until the ridge frame is completed.

[0028] Furthermore, the step S1 includes the following specific construction steps:

[0029] S1.1: Place the butt joint rod and the hook-shaped support rod on the ground frame and align one end of the butt joint rod with the end of the short rod of the hook-shaped support rod. Then, connect the butt joint rod and the short rod of the hook-shaped support rod with a connector and weld the butt joint surface of the butt joint rod and the short rod of the hook-shaped support rod.

[0030] S1.2: Repeat step S1.1 to complete the assembly of the V-shaped support columns in main beam sections I and III.

[0031] The step S2 includes the following specific construction steps:

[0032] S2.1: Place the V-shaped support column on the ground frame and align the two ends of the V-shaped support column with the two outer legs of the curved beam I. Connect the corresponding V-shaped support column ends to the legs using connectors and weld the joint surfaces of the V-shaped support column ends and the legs.

[0033] S2.2: Install the rocking column on the curved beam I according to the design requirements;

[0034] S2.3: Repeat steps S2.1 and S2.2 to complete the ground assembly of main beam segments I and III;

[0038] S3.3: Weld reinforcement rods between the tops of the two sets of curved beams II to complete the ground assembly of main beam segment II.

[0039] The beneficial technical effects of the present invention are:

[0040] 1. Main beam segment I can be stably installed on the concrete base with the support of V-shaped support columns. Main beam segment III can also be stably installed on the concrete base with the support of corresponding V-shaped support columns. Main beam segment II can be directly hoisted between main beam segments I and III using lifting equipment. The installation of main beam segments I and III does not require additional support frames, which can significantly reduce the construction cost of the ridge beam.

[0041] 2. The curved beam I is symmetrically arranged and welded to the curved beam II of the main beam segment II. The curved beam I on both sides can play a role in cohesive support for the curved beam II, thereby making the main beam of the ridge more stable and the structural strength higher;

[0042] 3. V-shaped support columns, main beam sections I, II, and III are all assembled on the ground or directly produced in the factory. There is no need to install them step by step according to the construction progress, which not only improves the construction speed but also reduces the construction cost.

[0043] 4. When lifting in sections, the support frames installed at the joints of adjacent sections on the same ridge beam can provide better support for the welding parts between the sections, which is more conducive to welding between the sections and ensures welding strength.

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0051] like Figure 1 and Figure 2As shown, in Example 1, a lantern-shaped ridge frame includes a concrete base 1 set on the ground. The concrete base 1 is symmetrically arranged on both sides of the construction site according to the design requirements. An embedded steel frame 11 is provided in the concrete base 1, and a support steel plate 12 is fixed on the top of the embedded steel frame 11. Specifically, the concrete base 1 is constructed according to the construction requirements, and shear bolts are fixed on the embedded steel frame 11, and the support steel plate 12 is located on the top of the concrete base 1. The shear bolts can strengthen the connection between the embedded steel frame 11 and the concrete base 1, and then strengthen the connection between the support steel plate 12 and the concrete base 1, so that the subsequent installation of the ridge main beam is more stable.

[0052] A ridge beam is provided on the mutually symmetrical concrete bases 1, with both ends of the ridge beam corresponding to the two mutually symmetrical concrete bases 1. Both ends of the ridge beam are fixed to the support steel plates 12 of the corresponding concrete bases 1.

[0053] The ridge main beam includes main beam segment I2, main beam segment II3 and main beam segment III4. Main beam segment I2 and main beam segment III4 are respectively arranged on both sides of main beam segment II3 and are symmetrically arranged about main beam segment II3.

[0054] like Figure 1-Figure 3 As shown, the main beam segment I2 and the main beam segment III4 both include an arc-shaped beam I51 and a V-shaped support column 52. The V-shaped support column 52 is arranged on the outer arc side of the arc-shaped beam I51, and both ends of the V-shaped support column 52 face the outer arc side of the arc-shaped beam I51.

[0055] Specifically, the V-shaped support column 52 includes a hook-shaped support rod 521 and a docking straight rod 522. The docking straight rod 522 is coaxially arranged with the short rod of the hook-shaped support rod 521. One end of the docking straight rod 522 faces the short rod of the hook-shaped support rod 521 and is fixedly connected to the short rod of the hook-shaped support rod 521 through a connecting member 6.

[0056] Two supporting legs 511 corresponding to the two ends of the V-shaped column are fixed on the outer arc side of the arc-shaped beam I 51. The two ends of the V-shaped support column 52, namely the long rod end of the hook-shaped support rod 521 and the end of the docking straight rod 522, are respectively connected to the corresponding supporting legs 511 through the connecting piece 6.

[0057] The connector 6 includes a reinforcing rib 61 and a wing plate 63. The wing plate 63 is fixed to the side walls of the two corresponding rods to be connected, with the wing plate 63 on the corresponding rod near the end to be connected. The reinforcing rib 61 is a straight steel plate and is fixed to the corresponding wing plates 63 by bolts 62. Specifically, the wing plates 63 on both sides of the long rod of the hook-shaped support rod 521 are fixed to the wing plates 63 on both sides of the corresponding support legs 511; the wing plates 63 on both sides of the short rod of the hook-shaped support rod 521 are fixed to the wing plates 63 on both sides of the corresponding connecting straight rod 522; and the wing plates 63 on both sides of the short rod of the hook-shaped support rod 521 are fixed to the wing plates 63 on both sides of the corresponding support legs 511. After the reinforcing rib 61 reinforces the wing plates 63 on the side walls of the rods to be connected, the opposite ends of the rods to be connected are welded to achieve a fixed connection between the rods to be connected.

[0058] In this embodiment, the corner ends of the V-shaped support columns 52 are disposed on the support steel plate 12 of the concrete base 1. Specifically, the corner ends of the V-shaped support columns 52 are provided with fixing surfaces that contact the support steel plate 12 on the concrete base 1. The corner ends of the V-shaped support columns 52 are fixedly connected to the support steel plate 12 via bolts 62.

[0059] Through the above arrangement, the construction of main beam segment I2 and main beam segment III4 can be completed respectively on two symmetrically arranged concrete bases 1. After the construction of main beam segment I2 and main beam segment III4 is completed, the construction of main beam segment II3 can be carried out.

[0060] Main beam segment II3 is located between main beam segments I2 and III4. It comprises two symmetrical curved beams II71 and two symmetrical V-shaped connecting rods 72. Specifically, the two curved beams II71 are arranged in an "eight" pattern and correspond to curved beams I51 of main beam segment I2 and I51 of main beam segment III4, respectively. Curved beams II71 are located on the extended arcs of their corresponding curved beams I51 and are fixedly connected to them by welding.

[0061] Two V-shaped connecting rods 72 are located between the two curved beams II 71 and are fixed to each of them. The ends of the V-shaped connecting rods 72 are fixed to the outer arc of the corresponding curved beams II 71. The corner ends of the two V-shaped connecting rods 72 are close to each other and are each provided with a welding surface. The welding surfaces of the two V-shaped connecting rods 72 abut against each other, and the two V-shaped connecting rods 72 are fixed together by welding.

[0062] A reinforcement rod 73 is welded between the top ends of the two curved beams II 71. In the present invention, the two welded V-shaped connecting rods 72 can make the two curved beams II 71 form a whole, and the reinforcement rod 73 connected between the top ends of the curved beams II 71 can strengthen the structural strength of the entire main beam segment II 3.

[0063] like Figure 1 and Figure 4 As shown, in the present invention, a swing column 512 is hingedly connected to curved beam I 51. This column 512 is located on the side of the hook-shaped support rod 521 away from the connecting rod 522 and near one end of curved beam I 51. The bottom end of the swing column 512 is hingedly connected to the concrete frame surrounding the main ridge beam. Specifically, the concrete frame surrounding the main ridge beam is a building structure installed on the ground. The swing column 512 installed on the concrete frame not only provides traction for curved beam I 51 but also provides reverse support, allowing curved beam I 51 to better provide force-gathering support for curved beam II 71.

[0064] The completed main beam segment I2, main beam segment II3 and main beam segment III4 can form a symmetrical "𠘨"-shaped structure, which is the lantern ridge main beam. The symmetrical structure has good stability. At the same time, the V-shaped support column 52 can gather the bearing force to its tip and transfer it to the concrete base 1, which can provide stable support for the entire ridge main beam.

[0065] In the present invention, both the main beam segment I2 and the main beam segment III4 are directly hoisted on the corresponding concrete base 1 by hoisting equipment, and no additional support frame is required during the hoisting process, which makes the construction cost of the ridge main beam low. Moreover, the main beam segment I2 can be stably set on the concrete base 1 under the support of the V-shaped support column 52, and the main beam segment III4 can be stably set on the concrete base 1 under the support of the corresponding V-shaped support column 52. The main beam segment II3 can be directly hoisted between the main beam segment I2 and the main beam segment III4 by hoisting equipment. The main beam segment I2 and the main beam segment III4 can directly serve as support for the main beam segment II3, and no additional support frame is required, which further reduces the construction cost of the ridge main beam.

[0066] In addition, the symmetrically arranged arc beams Ⅰ51 can have a good force-gathering effect on the main beam segment Ⅱ3, making the installation of the main beam segment Ⅱ3 more stable, and thus making the structure of the overall ridge main beam more stable.

[0067] Example 2:

[0068] A construction method for a lantern-shaped ridge frame as described in Example 1 comprises the following construction steps:

[0069] S1: Complete the ground assembly of the V-shaped support column 52.

[0070] The specific construction steps included in step S1 are:

[0071] S1.1: Place the butt joint rod 522 and the hook-shaped support rod 521 on a tire frame on the ground, and align one end of the butt joint rod 522 with the end of the short rod of the hook-shaped support rod 521. Then, connect the butt joint rod 522 and the short rod of the hook-shaped support rod 521 through the connector 6 and weld the butt joint surface between the butt joint rod 522 and the short rod of the hook-shaped support rod 521.

[0072] S1.2: Repeat step S1.1 to complete the assembly of the V-shaped support columns 52 in the main beam segment I2 and the main beam segment III4.

[0073] S2: Complete the ground assembly of main beam segment I2 and main beam segment III4.

[0074] The specific construction steps included in step S2 are:

[0075] S2.1: Place the V-shaped support column 52 on the ground frame, aligning the ends of the V-shaped support column 52 with the two outer legs 511 of the curved beam I 51. Connect the corresponding ends of the V-shaped support column 52 to the legs 511 using connectors 6, and weld the joint surfaces of the ends of the V-shaped support column 52 and the legs 511.

[0076] S2.2: Repeat step S2.2 to complete the ground assembly of main beam segment I2 and main beam segment III4.

[0077] In the above steps S1 and S2, when the connecting member 6 connects the two corresponding connected rods, it is first necessary to make the connected sides of the two rods to be connected touch each other, and make the wing plates 63 on the side walls of each rod correspond to each other, and then the reinforcing ribs 61 are attached to the corresponding wing plates 63 on the side ground of the two rods to be connected, and then the wing plates 63 and the reinforcing ribs 61 thereon are fixed by bolts 62 to achieve the preliminary connection of the two connected rods, and then the abutting sides of the two rods to be connected are welded to complete the fixed connection between the hook-shaped support rods 521 in the main beam segment Ⅰ2 and the main beam segment Ⅲ4 and the connecting straight rods 522 and the arc beam Ⅰ51 legs 511.

[0078] S3: Complete the assembly of main beam segment II3 on the ground.

[0079] The specific construction steps included in step S3 are:

[0080] S3.1: Place V-shaped connecting rod 72 on the tire frame on the ground. V-shaped connecting rod 72 is located on the outer arc side of curved beam II 71. Weld both ends of V-shaped connecting rod 72 to curved beam II 71 according to design requirements.

[0081] S3.2: Arrange the two sets of curved beams II 71 symmetrically and align the welding planes of the corner ends of the two symmetrical sets of V-shaped connecting rods 72 for welding;

[0082] S3.3: Weld reinforcement rods 73 between the top ends of the two sets of curved beams II 71 to complete the ground assembly of main beam segment II 3.

[0083] S4: Cut off the reinforcing ribs 61 on the side of the supporting legs 511 , the side of the hook-shaped support rod 521 , and the side of the connecting straight rod 522 .

[0084] When main beam segment I2 and main beam segment III4 are assembled on the ground or in the factory, the reinforcing ribs 61 on the side of the support legs 511, the side of the hook-shaped support rods 521 and the side of the connecting straight rods 522 are cut off, and the cut parts are smoothed to make main beam segment I2 and main beam segment III4 more beautiful and more integrated.

[0085] S5: Move the main beam segment Ⅰ2 to the top of the preset concrete base 1 through the lifting equipment, fix the corresponding V-shaped support column 52 on the corresponding concrete base 1 and install the corresponding swing column 512 on the corresponding concrete frame, and then pull the guy rope on both sides of the corresponding curved beam Ⅰ51.

[0086] The main beam segment I2 is set behind the concrete base 1. Since the subsequent main beam segment II3 needs to be installed, in order to ensure the normal installation of the main beam segment II3, the installed main beam segment I2 needs to be reinforced. The guy ropes arranged on both sides of the corresponding curved beam I51 play a better reinforcement role on the V-shaped support column 52 and the curved beam I51, so that the main beam segment I2 has better stability.

[0087] S6: Use the lifting equipment to move the main beam segment III4 to the top of the preset concrete base 1, fix the corresponding V-shaped support column 52 on the corresponding concrete base 1, and install the corresponding swing column 512 on the corresponding concrete frame. Then, the main beam segment III4 is symmetrically arranged with the main beam segment I2, and guy ropes are stretched on both sides of the curved beam I 51 of the main beam segment III4.

[0088] After the main beam segment III4 is set on the concrete base 1, the subsequent main beam segment II3 needs to be installed. In order to ensure the normal installation of the main beam segment II3, the installed main beam segment III4 needs to be reinforced. The guy ropes installed on both sides of the corresponding curved beam I51 play a better reinforcement role on the V-shaped support column 52 and the curved beam I51, so that the main beam segment III4 has better stability.

[0089] S7: A support frame 8 is set on the side where the main beam segment I2 and the main beam segment III4 are close to each other. The support frame 8 is set below the end where the main beam segment I2 and the main beam segment III4 are close to each other.

[0090] The support frame 8 can support the ends of the main beam segment I2 and the main beam segment III4 that are close to each other, which is more conducive to the subsequent installation of the main beam segment II3.

[0091] S8: If it is the first time to construct the ridge main beam, two groups of the above-mentioned main beam segment Ⅰ2 and main beam segment Ⅲ4 need to be set up during construction, and purlins 9 need to be fixed between the two adjacent main beam segments Ⅰ2 and the adjacent main beam segments Ⅲ4, and then step S9 is performed. If it is not the first time to construct the ridge main beam, purlins 9 need to be fixed between the main beam segment Ⅰ2 constructed later and the main beam segment Ⅰ2 adjacent to it, and between the main beam segment Ⅲ4 constructed later and the main beam segment Ⅲ4 adjacent to it, and then step S9 is performed.

[0092] The purlin 9 can reinforce the adjacent main beam segment I2 and the adjacent main beam segment III4. The purlin 9 is fixed between the corresponding curved beams I51. There are multiple purlins 9, and the multiple purlins 9 are evenly distributed along the arc length of the curved beam I51.

[0093] S9: Use the lifting equipment to lift the main beam segment II3 to between the main beam segment I2 and the main beam segment III4, and make the two ends of the main beam segment II3 respectively located on the support frame 8 on the corresponding side.

[0094] The support frame 8 can support the connection between the main beam segment II3 and the main beam segment I2, and the main beam segment III4, so that the main beam segment II3 and the main beam segment I2, and the main beam segment III4 are welded and fixed with better stability and higher welding quality.

[0095] S10: The construction workers weld the corresponding curved beams I51 and II71 through a hanging basket or lifting equipment. After the welding is completed, the support frame 8 is removed to complete the construction of the ridge main beam.

[0096] When welding and fixing the curved beam I51 and the curved beam II71, the construction workers can perform the welding operation through a hanging basket provided on the support frame 8 or directly through lifting equipment such as a ladder, an aerial work platform vehicle and the like.

[0097] S11: Fix purlins 9 between adjacent main beam sections Ⅱ3.

[0098] The purlin 9 can strengthen the connection between the main beam segments II3 on adjacent ridge main beams, thereby connecting two adjacent ridge main beams into a whole with better stability.

[0099] S12: Repeat steps S1-S11 according to the design requirements until the ridge frame is completed.

[0100] In accordance with the design and construction requirements, multiple ridge beams are constructed at the construction site. The multiple ridge beams form the entire ridge frame, thereby completing the construction of the ridge frame.

[0101] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
