Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly relates to an assembled steel-wood trestle bridge. Background Art

[0002] During the construction process, it is necessary to build some temporary trestle bridges to serve the construction, so as to facilitate the building construction.

[0003] Currently, the construction trestle bridges generally adopt steel structures and concrete structures. After connecting the steel parts to form the required structure, the base of the steel structure is fixed by concrete to form a trestle bridge. The connection of the existing trestle bridge components is extremely inconvenient. At the same time, the concrete structure requires formwork support and has a certain curing period, which affects the construction progress. At the same time, the materials of the existing trestle bridge components cannot be reused, wasting a lot of manpower, material resources and financial resources.

[0004] Therefore, how to provide a trestle bridge that is easy to use and improves the on-site construction efficiency is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0005] The purpose of the present invention is to provide an assembled steel-wood trestle bridge, which is composed of combined columns, beams and plates, and is connected by the mortise and tenon method. The building method is simple, the building speed of the trestle bridge is improved, and it is beneficial to improve the on-site construction efficiency.

[0006] To solve the above technical problems, the present invention provides an assembled steel-wood trestle bridge, including combined columns, combined beams and combined plates. The combined columns include four wooden square columns and four steel square columns. The steel square columns are distributed in a cross shape. The wooden square columns are respectively arranged between adjacent steel square columns, and the wooden square columns are distributed in a rectangle. The height of the wooden square columns is greater than the height of the steel square columns, and is used to form an installation groove for clamping and installing the combined beams and arranged perpendicular to each other. The combined beams are clamped in the installation groove, and the combined plates are installed on the combined beams.

[0007] Preferably, the wooden square columns and the steel square columns are connected by bolts.

[0008] Preferably, the bolts are distributed staggeredly.

[0009] Preferably, the bottoms of the wooden square columns and the steel square columns are connected to the embedded parts of the base through studs.

[0010] Preferably, the combined beam includes a cross beam and a longitudinal beam. An upper opening groove is arranged on the longitudinal beam, and a lower opening groove is arranged on the cross beam.

[0011] Preferably, thin-walled steel sections are provided on the outer peripheries of the combined plates, the cross beams and the longitudinal beams.

[0012] Preferably, the thin-walled steel sections are fixedly installed by rivets.

[0013] The prefabricated steel-wood trestle provided by the present invention includes composite columns, composite beams and composite plates. The composite columns include four wooden square columns and four steel square columns. The steel square columns are distributed in a cross shape. The wooden square columns are respectively arranged between adjacent steel square columns and are distributed in a rectangle. The height of the wooden square columns is greater than that of the steel square columns, and is used to form mounting grooves for clamping and installing the composite beams and arranged perpendicular to each other. The composite beams are clamped in the mounting grooves, and the composite plates are installed on the composite beams. For the prefabricated steel-wood trestle of the present application, wooden square columns and steel square columns of different specifications and sizes are made according to the requirements of the construction site. The steel square columns are in a cross shape, and the height of the wooden square columns needs to be greater than that of the steel square columns. Install the four wooden square columns between the adjacent cross-shaped columns of the steel square columns and make the bottoms of the wooden square columns and the steel square columns flush. Due to the height difference between the wooden square columns and the steel square columns, mounting grooves perpendicular to each other are formed at the tops of the wooden square columns and the steel square columns. Make four composite columns in sequence, assemble the wooden beams and channel steel beams according to different sizes to form composite beams. Similarly, make four composite beams, two long composite beams and two short composite beams. Splice steel channels and wooden boards of different specifications to form composite plates. Fix the bottoms of the four composite columns at the construction position, splice the composite beams with the composite columns, and connect the composite beams in two directions by mortise and tenon joints, biting together. Finally, connect the composite plates with the composite beams to form a temporary construction trestle. Through the combined composite columns, composite beams and composite plates, and connected by mortise and tenon joints, the building method is simple, the building speed of the trestle is increased, and it is beneficial to improve the on-site construction efficiency.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 5 , Figure 1 which is a schematic diagram of the overall structure of a specific implementation manner provided by the present invention; Figure 2 is Figure 1 a schematic assembly diagram of the cross beam and the longitudinal beam shown; Figure 3 is Figure 1 a schematic diagram of the combined column structure shown; Figure 4 is Figure 1 a bottom cross-sectional view of the structure shown; Figure 5 is Figure 3 a cross-sectional view of the combined column shown.

[0024] In a specific implementation manner provided by the present invention, it mainly includes a combined column 1, a combined beam 2 and a combined plate 3. The combined column 1 includes four wooden square columns 101 and four steel square columns 102. The steel square columns 102 are distributed in a cross shape. The wooden square columns 101 are respectively arranged between adjacent steel square columns 102, and the wooden square columns 101 are distributed in a rectangular shape. The height of the wooden square columns 101 is greater than the height of the steel square columns 102, and is used to form a mounting groove for clamping and installing the combined beam 2 and arranged perpendicular to each other. The combined beam 2 is clamped in the mounting groove. The combined column 1 and the combined beam 2 are connected by a mortise and tenon method to form a trestle structure, and the combined plate 3 is installed on the combined beam 2. The combined plate 3 serves as a construction platform.

[0025] Specifically, in the actual application process, wooden square columns 101 and steel square columns 102 of different specifications and sizes are made according to the requirements of the construction site. The steel square column 102 is cross-shaped, and the height of the wooden square column 101 needs to be greater than that of the steel square column 102. Four wooden square columns 101 are installed between the adjacent cross-shaped columns of the steel square column 102, and the bottoms of the wooden square column 101 and the steel square column 102 are flush. Due to the height difference between the wooden square column 101 and the steel square column 102, installation grooves perpendicular to each other are formed at the tops of the wooden square column 101 and the steel square column 102. Four combined columns 1 are made in sequence. According to different sizes, wooden beams and channel steel beams are assembled to form a combined beam 2. Similarly, four combined beams 2 are made, two long combined beams 2 and two short combined beams 2. Channels of different specifications and wooden boards are spliced to form a combined board 3. At the construction position, the bottoms of the four combined columns 1 are fixed, the combined beam 2 is spliced with the combined column 1, and the two-direction combined beams 2 are connected by mortise and tenon joints and bite together. Finally, the combined board 3 is connected with the combined beam 2 to form a temporary construction trestle.

[0026] In order to ensure that the prefabricated steel-wood trestle in the above embodiment has sufficient construction strength requirements, the wooden square column 101 and the steel square column 102 are connected by bolts 4, and the bolts 4 are staggered. By setting corresponding through holes in the wooden square column 101 and the steel square column 102, and connecting the adjacent wooden square column 101 and steel square column 102 through the bolts 4 in a through-length manner, the combined strength of the wooden square column 101 and the steel square column 102 is ensured, making the combined column 1 more in line with the on-site construction strength requirements. Field tests show that under the condition of the same cross-sectional size, the structural bearing capacity of the combined column 1 formed by the wooden square column 101 and the steel square column 102 is about 60% higher than that of the pure steel column structure, fully meeting the construction strength requirements of the construction site.

[0027] Based on this, the bottoms of the wooden square column 101 and the steel square column 102 are both connected to the embedded part 7 of the base 6 through studs 5. First, the embedded part 7 is embedded into the base 6. The bottom of the steel square column 102 at the lower end face of the combined column 1 is welded to the embedded part 7, and the embedded part 7 is connected to the concrete base 6 through the stud 5. The combined column 1 is connected to the base 6 through the stud 5 and the embedded part 7, ensuring the fixing strength of the combined column 1 itself and making the formed trestle structure more stable.

[0028] Furthermore, the composite beam 2 includes a cross beam 201 and longitudinal beams 202. Upper opening grooves are provided on the longitudinal beams 202, and lower opening grooves are provided on the cross beam 201. At the upper end of the composite column 1, the steel square column 102 does not extend, leaving an installation groove position between the wooden square column 101 and the steel square column 102, which facilitates the placement of the cross beam 201 and the longitudinal beams 202. After placing the composite column 1 and the composite beam 2, at the upper beam-column joint of the composite column 1, the wooden square column 101 extends to the top of the composite beam 2 flush, and the steel square column 102 extends to the bottom of the composite beam 2 flush. The cross beam 201 in the long-span direction has a groove downward at the beam-column joint, and the longitudinal beam 202 in the short-span direction has a groove upward. After splicing the two, the top of the cross beam 201 and the longitudinal beams 202 is flush with the top of the composite column 1, and the bottom of the cross beam 201 and the longitudinal beams 202 is flush with the bottom of the steel square column 102.

[0029] It should be noted that thin-walled steel sections 7 are provided on the outer peripheries of the composite slab 3, the cross beam 201, and the longitudinal beams 202. The composite beam 2 is assembled by riveting a wooden square and the thin-walled steel section 7. The two sides of the cross beam 201 and the longitudinal beams 202 are connected to the channel steel by rivets 8. The thin-walled steel section 7 is truncated at the beam-column joint, and grooves are left on the cross beam 201 and the longitudinal beams 202 for easy lapping. Similarly, the composite slab 3 is composed of a wooden board and the thin-walled steel section 7, and the connection between the wooden board and the thin-walled steel section 7 is achieved by riveting 8.

[0030] In summary, the prefabricated steel-wood trestle provided in this embodiment mainly includes composite columns, composite beams, and composite slabs. The composite columns include four wooden square columns and four steel square columns. The steel square columns are distributed in a cross shape, and the wooden square columns are respectively arranged between adjacent steel square columns and are distributed in a rectangular shape. The height of the wooden square columns is greater than that of the steel square columns, and installation grooves for clamping and installing the composite beams and arranged perpendicular to each other are formed. The composite beams are clamped in the installation grooves, and the composite slabs are installed on the composite beams. For the prefabricated steel-wood trestle of the present application, wooden square columns and steel square columns of different specifications and sizes are fabricated according to the requirements of the construction site. The steel square columns are cross-shaped, and the height of the wooden square columns needs to be greater than that of the steel square columns. The four wooden square columns are installed between the adjacent cross-shaped columns of the steel square columns, and the bottoms of the wooden square columns and the steel square columns are made flush. Due to the height difference between the wooden square columns and the steel square columns, installation grooves perpendicular to each other are formed at the tops of the wooden square columns and the steel square columns. Four composite columns are fabricated in sequence, and the wooden beams and channel steel beams are assembled according to different sizes to form composite beams. Similarly, four composite beams are fabricated, two long composite beams and two short composite beams. The channel steel and wooden boards of different specifications are spliced to form composite slabs. The bottoms of the four composite columns are fixed at the construction position, the composite beams are spliced with the composite columns, and the composite beams in two directions are connected by mortise and tenon joints and bite together. Finally, the composite slabs are connected to the composite beams to form a temporary construction trestle. Through the combined composite columns, composite beams, and composite slabs, which are connected by the mortise and tenon method, the construction method is simple, the construction speed of the trestle is increased, and it is beneficial to improve the on-site construction efficiency.
