Description

Technical Field

[0001] The invention belongs to the technical field of steel-wood structure building construction, and particularly relates to a large-span steel-wood installation structure and an installation method. Background Art

[0002] Steel-wood structure is a hybrid structure characterized by its traditional architectural style and durability. Wood-clad steel is a common steel-wood structure, with the steel structure as the main load-bearing structure and the wood material as the outer insulation.

[0003] An equestrian center is a venue used for equestrian competitions and related activities. It typically includes competition venues, warm-up areas, training grounds, high-standard stables, and offers spectator seating, VIP stands, sky boxes, and other viewing facilities. Equestrian centers not only host various equestrian competitions but also often integrate events, horse inspection and quarantine, industry exchange and cooperation, equestrian culture and art, and youth education and training.

[0004] Wood is a common building material in equestrian centers. It has thermal insulation properties and absorbs water and microorganisms, reducing the growth of moisture and mold. Furthermore, wood protects horses' legs and hooves from kicking against the walls. Even if stable partitions are made of other durable materials, such as brick, they can be covered with wooden panels to mitigate the forces of kicking and protect the horses. Wood structures effectively address the thermal bridge issues often associated with steel structures, significantly improving insulation and energy conservation.

[0005] Large-span structures generally refer to buildings with horizontal spans exceeding 30 meters. These structures are often used in industrial buildings, such as large-span factories, aircraft assembly plants, and large warehouses. Large-span structures are a key indicator of a country's architectural technology.

[0006] The existing shortcoming is that when constructing large-span steel-wood structures, due to the large size of the components, the construction site environment and equipment construction requirements are high, and the construction is inconvenient. Summary of the Invention

[0007] The purpose of the present invention is to provide a large-span steel-wood installation structure and installation method to address the problems existing in the prior art. The solution has the advantages of convenient construction, stable structure and splicing installation.

[0008] To achieve the above object, the technical solution adopted by the present invention is: a large-span steel-wood installation structure, including a number of support wooden frames arranged in parallel. The support wooden frame includes a large-span cross beam and cross beam installation columns located at both ends of the large-span cross beam. The large-span cross beam includes two single beams arranged opposite to each other. The single beam includes a number of cross beam units spliced in sequence. A connecting member is provided between adjacent cross beam units; support portions for installing the single beam are provided on both sides of the top of the cross beam installation column. The large-span cross beam is fixed to the cross beam installation column through fasteners; a diagonal support for supporting the large-span cross beam is connected to the cross beam installation column; a number of glued laminated wood members are provided between the large-span cross beams of adjacent support wooden frames.

[0009] In the above solution, the large-span cross beam has a large span. A structure of splicing a number of cross beam units in sequence through connecting members and using a combination of two single beams is adopted to facilitate hoisting and construction. Support portions are provided on both sides of the top of the cross beam installation column to support the bottom of the large-span cross beam, and then the large-span cross beam is fastened through fasteners. A diagonal support is provided on the cross beam installation column to support the large-span cross beam, and glued laminated wood members are provided between adjacent support wooden frames to connect them into a whole.

[0010] Further, a number of temporary support columns are provided between the two cross beam installation columns. A cushion block for supporting the bottom surface of the large-span cross beam is provided on the top of the temporary support column.

[0011] By providing temporary support columns to support the large-span cross beam during construction to ensure the structural stability, and providing cushion blocks to contact the bottom of the large-span cross beam to ensure the support effect.

[0012] Further, positioning holes are correspondingly provided at both ends of the connecting member on the cross beam unit. A connecting pin shaft for connecting the connecting member and the cross beam unit is provided in the positioning hole. An installation slot for connecting the connecting member is provided at the end of the cross beam unit.

[0013] After the connecting member is installed in the installation slot at the end of the cross beam unit, the connecting member is aligned with the positioning hole on the cross beam unit, and the connecting member and the cross beam unit are connected through the connecting pin shaft, thus completing the splicing of adjacent cross beam units. The shape of the installation slot matches that of the connecting member.

[0014] Further, the connecting member includes a middle metal plate and two U-shaped metal parts arranged opposite to each other. The middle metal plate is located between the upper and lower U-shaped metal parts.

[0015] Positioning holes are provided on both the two U-shaped metal parts and the middle metal plate to ensure the connection stability between adjacent cross beam units.

[0016] Further, a wood filling block is provided between the opposite single beams, and a long pin shaft is provided between the opposite single beams. The long pin shaft passes through the wood filling block.

[0017] The relative position between the two single beams is ensured by setting wooden filling blocks to enhance the structural strength, and long pins are set to position the wooden filling blocks.

[0018] Furthermore, mounting holes are correspondingly opened on the crossbeam mounting columns and the single beams, and fastening bolt assemblies for connecting the single beams on both sides and the crossbeam mounting columns are provided at the mounting holes.

[0019] The single beams on both sides are connected and fixed on the beam mounting columns by tightening the bolt assembly, which is easy to operate.

[0020] The present invention also discloses a method for installing a large-span steel-wood installation structure, comprising the following steps: S1. Set up temporary support columns and beam installation columns. Place wooden blocks on top of the temporary support columns to support the long-span beams. After hoisting the single beam into place, connect the single beam to the installation columns. Then hoist the single beam on the other side to complete the fixation of the long-span beams on both sides of the installation columns. S2. After confirming the position of the temporary support column and installation column of the next beam, proceed with the installation of the next supporting wooden frame in sequence according to step S1; after completing the installation of the current large-span beam, connect several glulam rods between the current large-span beam and the previous large-span beam; S3. Repeat step S2 to complete the construction of the remaining supporting wooden frames and glued wood rods to form the frame body.

[0021] In the above scheme, S1 first sets up the beam installation column and the temporary support column, and sets the pad on the top of the temporary support column to ensure the support of the bottom of the large-span beam, which is convenient for fastening and fixing the large-span beam. During construction, the single beam is connected on one side first, and then the other side is hoisted and connected, which is convenient for construction, reduces the single hoisting load, and improves safety; S2 then installs the next supporting wooden frame according to the steps in S1, and sets plywood rods between the two large-span beams. S3 completes the installation of the remaining supporting wooden frames and plywood rods according to S2, installs the large-span frame, and constructs the top frame structure on the top of the frame body.

[0022] Furthermore, step S1 includes the following steps: building an assembly platform frame, hoisting the beam units to the top of the assembly platform frame, and assembling the beam units into a single beam through connectors.

[0023] By building an assembly platform frame, it is convenient to assemble the beam units into single beams. The assembly platform frame is lower than the beam installation column, which facilitates the assembly operation and reduces the risk of the beam falling.

[0024] Furthermore, a roller for axially moving the beam unit is provided on the top of the assembly platform frame.

[0025] The rollers are provided to facilitate axial movement of the beam unit and facilitate assembly operations.

[0026] Furthermore, the steps for installing the single beam in step S1 are as follows: S11. Fasten the single beam on one side to the crossbeam mounting column using short fasteners; S12. After hoisting the other side single beam to the support part, use extended fasteners to connect the two side single beams and the beam mounting column; S13. Remove the short fasteners, install the fastening bolt assembly, and replace the extended fasteners with the fastening bolt assembly.

[0027] When installing the single beam on site, first fasten the single beam on one side to the beam mounting column with short fasteners to free up the lifting equipment for lifting the single beam on the other side. After S12 lifts the single beam on the other side to the support part and aligns it, use long fasteners to perform preliminary connection and limit the single beams and beam mounting columns on both sides to prevent the single beam from moving over a large range when the short fasteners are removed. Finally, fasten the single beams on both sides with the fastening bolt assembly, and replace the extended fasteners with the fastening bolt assembly.

[0028] Compared with the prior art, the present invention has the following beneficial effects: 1. The long-span beam is formed by setting two opposing single beams. Each single beam is spliced ​​by multiple beam units. After splicing near the installation location on site, it is directly hoisted and installed, reducing the hoisting distance of the long-span beam and improving construction efficiency. The beam unit is small in size and light in weight, with low requirements on the site environment and equipment, and is easy to transport and install. 2. During construction, temporary support columns were installed, and the supporting wooden frame and glued wood rods were constructed in sequence to ensure the structural stability of the long-span beams on the supporting wooden frame; 3. By building an assembly platform frame, it is convenient to set the connecting parts and perform the assembled connection of adjacent beam units, which ensures a stable structure and fast construction.

[0046] The single beams 2 on both sides are connected and fixed to the crossbeam installation column 1 through the fastening bolt assemblies, which is convenient for operation.

[0047] The present invention also discloses an installation method for a long-span steel-wood installation structure, including the following steps: S1. Set up the temporary support column 12 and the crossbeam installation column 1, set a cushion wood 13 for supporting the long-span crossbeam at the top of the temporary support column 12, after hoisting the single beam 2 in place, connect the single beam 2 with the installation column; then hoist the single beam 2 on the other side to complete the fixation of the long-span crossbeams on both sides of the installation column; S2. After confirming the positions of the temporary support column 12 and the installation column of the next crossbeam, according to step S1, sequentially install the next support wooden frame; after completing the installation of the current long-span crossbeam, connect a number of glued wood members 10 between the current long-span crossbeam and the previous long-span crossbeam; S3. Repeat step S2 to complete the construction of the remaining supporting wooden frames and glued wood rods 10 to form the frame body.

[0048] In the above scheme, S1 first sets up the beam installation column 1 and the temporary support column 12, and sets the pad 13 on the top of the temporary support column 12 to ensure the support of the bottom of the large-span beam, which is convenient for fastening the large-span beam in position. During construction, the single beam 2 on one side is connected first, and then the other side is hoisted and connected, which is convenient for construction, reduces the single hoisting load, and improves safety; S2 then installs the next supporting wooden frame according to the steps in S1, and sets the glued wood rod 10 between the two large-span beams. S3 completes the installation of the remaining supporting wooden frames and glued wood rods 10 according to S2, installs the large-span frame, and constructs the top frame structure 11 on the top of the frame body.

[0049] The top frame structure 11 includes a herringbone frame connecting adjacent large-span beams and a connecting beam perpendicular to the herringbone frame.

[0050] Furthermore, step S1 includes the following steps: building an assembly platform frame 19, hoisting the beam unit 201 to the top of the assembly platform frame 19, and assembling the beam unit 201 into a single beam 2 through connectors.

[0051] The assembly platform frame 19 is constructed to facilitate the assembly of the beam unit 201 into a single beam 2. The assembly platform frame 19 is lower than the beam mounting column 1, which facilitates the assembly operation and reduces the risk of the beam falling.

[0052] Before assembling the wooden beams, a 130t crane is first used to assemble the platform cradle 19. After installing the assembly platform cradle 19, a spirit level is used to check the cradle elevation to ensure the accuracy of the wooden beam assembly. After the assembly is completed, a truck crane is used to lift the large-span beams from west to east.

[0053] The vertical height of the large-span beam hoisted on the assembly platform frame 19 is 15m. The total length of the large-span beam is 96m, which is divided into 6 sections of 14m+18m+18m+18m+18m+10m.

[0054] When assembling long-span beams, ensure that all metal connectors, reinforcement hardware, bolts, and metal pins are fully secured. The two crane slings are aligned at a 65° angle, and 10mm x 20m traction ropes are installed at both ends. A test hoisting test is conducted at a height of 0.5m above the assembly platform. Only after the hoisting test is stable and clear of any safety hazards can the official hoisting be carried out.

[0055] After the large span beam is hoisted into place, it must be bolted to the metal beam mounting column 1 before the sling can be removed. The wooden filler block 15300*500*500 is reinforced with wood screws according to the size.

[0056] After the double-piece large-span beams are hoisted, the slings can be removed only after the bolts, metal pins and wood screws are reinforced in time.

[0057] Furthermore, a roller 20 for axially moving the beam unit 201 is provided on the top of the assembly platform frame 19 .

[0058] The roller 20 is provided to facilitate the axial movement of the beam unit 201 and facilitate the assembly operation.

[0059] Furthermore, the steps for installing the single beam 2 in step S1 are as follows: S11, fastening the single beam 2 on one side to the crossbeam mounting column 1 using the short fastener 8; S12, after hoisting the other side single beam 2 to the support portion 7, use the extended fastener 21 to connect the two side single beams 2 and the beam mounting column 1; S13, remove the short fastener 8, install the fastening bolt assembly, and replace the lengthened fastener 21 with the fastening bolt assembly.

[0060] When installing the single beam 2 on site, first fasten the single beam 2 on one side to the beam mounting column 1 through the short fasteners 8, so as to free up the lifting equipment to lift the single beam 2 on the other side. S12 lifts the single beam 2 on the other side to the support part 7. After alignment, use long fasteners to perform preliminary connection and limit the single beams 2 and the beam mounting column 1 on both sides to prevent the single beam 2 from moving over a large range when the short fasteners 8 are removed. Finally, fasten the single beams 2 on both sides by the fastening bolt assembly, and replace the lengthened fasteners 21 with the fastening bolt assembly.

[0061] A plurality of positioning holes 6 are correspondingly provided on the single beam 2 and the crossbeam mounting column 1 to facilitate the replacement operation of the lengthened fastener 21 with a permanently fixed fastening bolt assembly.

[0062] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
