Description

Technical Field

[0001] The present invention relates to the technical field of steel structures, in particular to a lattice column steel structure system and a matching installation process. Background Art

[0002] In a beam steel structure system with a certain span, columns are usually set at the bottom of both ends of the beam to support the beam. Traditional beam steel structures use ordinary column structures for support.

[0003] For example, in the patent document with patent application number CN201720300908.3, a steel box beam is disclosed, whose main structure includes two box plates, two transverse plates, a partition and a mounting plate, the box plates and the transverse plates are vertically welded and fixed to form a cavity on the inner side, the partition is arranged in the cavity, the two ends of the partition are respectively welded to the box plates, the mounting plate is welded to the two ends of the box plates and the transverse plates, a first threaded hole is provided around the mounting plate, a reinforcing rib is welded at the outer connection of the box plate and the transverse plate, the reinforcing rib is arranged in a triangular shape, mounting seats are provided at the two ends of the bottom of the lower transverse plate, the mounting seat includes a bottom plate and baffles welded on both sides of the bottom plate, a rubber plate is provided between the baffles, second threaded holes are distributed on both sides of the bottom plate, a vertical plate is equidistantly welded in the middle of the upper transverse plate, through holes are provided around the vertical plate, and a reinforcing plate is welded in the middle of the front end of the vertical plate.

[0004] It can be seen from the records of the above patent that during installation, the base plate is fixed to the column by passing the fixing bolts through the second threaded holes. This simple structure that relies on the end of the beam to support the column can only play a role of rigid support during support.

[0005] However, when encountering working conditions that require support and resistance to wind loads, the comprehensive performance of the overall steel structure support and variable loads cannot be well guaranteed. Therefore, it is not suitable for engineering construction in outdoor environments with harsh outdoor environments and severe wind loads and variable loads.

[0006] Taking into account the stability of the span beam under harsh variable load environments, the present invention is designed and improved on the basis of the traditional beam-column structure, and the entire steel structure is optimized based on the lattice column structure. Considering that lattice columns are often used as compression-bending members, the material area can be arranged far away from the inertia axis, which can ensure the enhanced bending performance of the member under the same axial resistance conditions and save materials.

[0037] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only used as examples and are not intended to limit the scope of protection of the present invention. Figure 1-Figure 4 As shown in . Example 1:

[0038] The lattice column steel structure system includes a horizontally arranged large-span steel structure beam group 1, and lattice column assemblies are respectively installed at the bottom of both ends of the large-span steel structure beam group 1. The bottom of each lattice column assembly is pre-buried and fixed below the ground. A wind-load linkage mechanism is provided between the two lattice column assemblies. The upper ends of the wind-load linkage mechanism are respectively connected to the bottom of the middle section of the large-span steel structure beam group 1, and the lower ends are respectively installed in the foundation pit 2 below the ground. The middle section of the wind-load linkage mechanism extends to the left and right sides respectively and is respectively connected to the middle section of the lattice column assembly at the corresponding position.

[0039] After installation and construction, the lattice column steel structure system of the present invention forms a system in which both ends are stably supported by lattice column assemblies, and the middle part relies on the large-span steel structure beam group 1 as the upper bearing member, which can effectively ensure the stability and firmness of the support. At the same time, a wind load linkage mechanism is added at the bottom of the middle section of the large-span steel structure beam group 1 to adapt to the application in engineering environments in remote outdoor areas with relatively severe wind loads. The entire wind load linkage mechanism can play the role of buffering and offsetting the load by relying on damping when the system is subjected to wind load. At the same time, the entire wind load linkage mechanism is connected to the fixed linkage members of the lattice column assembly at the corresponding positions on both sides during operation. It can be linked to the integrated pre-assembled parts inside the inner cavity of the vertical lattice column 3 of the corresponding lattice column assembly according to the changes in the upper and lower positions of the upper large-span steel structure beam group 1 when subjected to load changes to achieve buffering and lifting adjustment, thereby driving the corresponding fixed linkage member to achieve follow-up lifting, so that after the fixed linkage member is lifted and lowered, the end of the tie wire rope 23 on the wind load linkage mechanism connected to it is driven to appropriately lift and lower, thereby achieving the effect of matching and buffering.

[0040] In any of the above schemes, it is preferred that the lattice column assembly includes a vertically arranged vertical lattice column 3, a load-bearing column 5 is installed on the top of the lattice column cavity 4 of the vertical lattice column 3, a load-bearing seat 6 is fixed on the top of the load-bearing column 5, the top of the load-bearing seat 6 is bolted to the connecting seat 7 at the bottom of the large-span steel structure beam group 1, an upper shock absorber 8 is installed between the load-bearing column 5 and the vertical lattice column 3, a lifting seat 9 is slidably installed in the lattice column cavity 4 below the load-bearing column 5, an upper pressure seat 10 is fixedly installed at the bottom of the load-bearing column 5, and an upper spring 11 is installed in the lattice column cavity 4 between the upper pressure seat 10 and the lifting seat 9. A top height adjustment support is installed in the lattice column cavity 4 below the lifting seat 9, and a lower spring 12 is installed inside the lattice column cavity 4 between the top height adjustment support and the lifting seat 9. The top of the lower spring 12 abuts against the bottom of the lifting seat 9, and the bottom abuts against the top of the top height adjustment support. A long through-open groove 13 is provided from top to bottom on the side wall of the lattice column cavity 4 facing the wind-loaded linkage mechanism, and a fixed linkage is fixedly installed on the side wall of the lifting seat 9 facing the wind-loaded linkage mechanism, and the fixed linkage is connected to the corresponding side of the wind-loaded linkage mechanism; the bottom of the vertical lattice column 3 is pre-embedded and fixed in the concrete pouring area 14 below the ground.

[0041] The overall support of the vertical lattice column 3 is relatively strong. A load-bearing column 5 is inserted in the top cavity of the vertical lattice column 3. Relying on the supporting effect of the load-bearing seat 6 on the top of the load-bearing column 5, effective support for the large-span steel structure beam group 1 can be achieved to ensure its support effect.

[0042] The upper shock absorber 8 can be made of rubber or spring shock absorbers, which mainly serves the purpose of coping with wind loads, so that the entire large-span steel structure beam group 1 can be controlled to move within a certain height range. At the same time, the load-bearing columns 5 can be used to limit the circumference to ensure the verticality of the large-span steel structure beam group 1.

[0043] The top height adjustment support installed in the cavity of the vertical lattice column 3 can adjust its height in advance or during the later maintenance process as needed to adjust the position of the fixed linkage part on its top and control the tightening force of the lower spring 12 at the corresponding position to cope with different wind loads and variable loads under later working conditions.

[0044] In any of the above schemes, it is preferred that the top height adjustment support member includes a vertical screw 15 fixedly installed at the bottom of the lattice column cavity 4 of the vertical lattice column, and a lifting threaded riser 16 is threadedly installed on the top outer wall of the vertical screw 15, and a lower pressure seat 17 is installed on the top of the lifting threaded riser 16. The top of the lower pressure seat 17 abuts against the bottom of the lower spring 12, and a rotating crank 18 is fixedly installed on the outer wall of the lifting threaded riser 16.

[0045] When adjusting, the top height adjustment support can drive the corresponding top threaded riser 16 to rise or fall by rotating the rotating crank 18, and finally achieve the purpose of driving the corresponding lower pressure seat 17 to move up and down, thereby achieving the purpose of adjusting the movement.

[0046] In any of the above schemes, it is preferred that the fixed linkage part includes a fixed side seat 19 fixedly mounted on the side wall of the lifting seat 9 facing the wind-borne linkage mechanism, and a rope fixing ring 20 is fixedly mounted on the fixed side seat 19, and the rope fixing ring 20 is connected to the corresponding side end of the wind-borne linkage mechanism.

[0047] The fixed linkage part can be fixed to the tie wire rope 23 through the rope fixing ring 20, thereby ensuring the tensioning effect of the tie wire rope 23. At the same time, the other end of the tie wire rope 23 is connected to the lower horizontal damper 27 to ensure the firmness of the connection of the entire tie wire rope 23. At the same time, the control of the horizontal damper 27 can achieve a buffering linkage effect when responding to loads.

[0048] In any of the above schemes, it is preferred that the wind-load linkage mechanism includes a central positioning top seat 21 fixedly installed in the middle section of the large-span steel structure beam group 1, and an upper pulley reversing group 22 is fixedly installed at the bottom of the central positioning top seat 21 at intervals along its left and right directions, and a tie wire rope 23 is clamped around each of the upper pulley reversing groups 22, and the lower end of each tie wire rope 23 extends vertically downward and is respectively connected to the damping buffer assembly installed inside the ground foundation pit 2, and the upper end of each tie wire rope 23 passes around the upper pulley reversing group 22 at the corresponding position and extends to one side to the rope fixing ring 20 at the corresponding position, and a wire rope hook 24 is fixedly installed at the upper end of each tie wire rope 23, and each wire rope hook 24 is respectively clamped on the rope fixing ring 20 at the corresponding position.

[0049] When working, the wind-load linkage mechanism mainly relies on the corresponding two tie-knotted steel wire ropes 23 to connect the damping buffer assembly at the bottom with the fixed linkage parts on both sides. When connecting, it can be reversed by bypassing the upper pulley reversing group 22. At the same time, it can realize the downward pulling of the middle bottom of the large-span steel structure beam group 1, effectively matching the fixed linkage parts on both sides to achieve multi-point positioning and downward pulling of the entire large-span steel structure beam group 1, thereby ensuring the stability of the entire large-span steel structure beam group 1 structure.

[0050] In any of the above schemes, it is preferred that the damping and buffering assembly includes a protective box 25 fixedly installed in the foundation pit 2 below the ground, and two lower wire rope reversing pulley groups 26 are symmetrically installed at intervals inside the protective box 25. The lower end of each of the tie wire ropes 23 extends from the through hole at the top of the protective box 25 to the inner cavity of the protective box 25. The lower end of each of the tie wire ropes 23 passes through the lower wire rope reversing pulley group 26 at the corresponding position and is converted into a horizontal shape and is fixedly connected to the output end of the horizontal damper 27 fixed at the corresponding position. Each of the horizontal dampers 27 is fixed relative to the ground.

[0051] After the damping buffer assembly is fixed, it can be fixedly tied to the tie wire rope 23 that is reversed to a horizontal state through the corresponding lower reversing pulley assembly 26 of the wire rope, thereby achieving the purpose of linking the tie wire rope 23 with the horizontal damper 27.

[0052] In any of the above solutions, preferably, a linkage locking mechanism is further installed on the upper part of the two tie wire ropes 23.

[0053] The interlocking locking mechanism includes two main pipe sleeves 28 respectively sleeved on the vertical sections of the tie wire rope 23 at corresponding positions, and the two main pipe sleeves 28 are tied and fixed by a connecting spring 29. A secondary pipe sleeve 30 is sleeved on the outer side wall of the inclined section of the tie wire rope 23 on one side of each main pipe sleeve 28, and a short-connecting steel wire rope 31 is fixedly connected to the outer side walls of the relatively arranged main pipe sleeve 28 and the secondary pipe sleeve 30, respectively. A short-connecting stud 32 and a short-connecting screw 33 are fixedly connected to the opposite ends of the two short-connecting steel wire ropes 31, respectively. The short-connecting stud 32 and the short-connecting screw 33 are fixedly connected by threaded engagement, and the main pipe sleeve 28 and the secondary pipe sleeve 30 are controlled by controlling the amplitude of the engagement of the short-connecting stud 32 and the short-connecting screw 33 to achieve tensioning of the inclined section and the vertical section of the same tie wire rope 23.

[0054] During installation, the interlocking locking mechanism mainly relies on controlling the amplitude of the screwing of the short-connecting stud 32 and the short-connecting screw 33 to control the main sleeve 28 and the auxiliary sleeve 30 to achieve the degree of tensioning of the inclined section and the vertical section of the same tie wire rope 23, thereby ensuring the firmness of the connection between the corresponding inclined section and the vertical section of the same tie wire rope 23, and playing the role of self-locking the same tie wire rope 23. The tie wire rope 23 after self-locking can be used as a tensioning tie member, and adjusting the tensioning force can control the comprehensive effect of the damping buffer and the spring buffer on both sides. Example 2:

[0055] The lattice column steel structure system includes a horizontally arranged large-span steel structure beam group 1, and lattice column assemblies are respectively installed at the bottom of both ends of the large-span steel structure beam group 1. The bottom of each lattice column assembly is pre-buried and fixed below the ground. A wind-load linkage mechanism is provided between the two lattice column assemblies. The upper ends of the wind-load linkage mechanism are respectively connected to the bottom of the middle section of the large-span steel structure beam group 1, and the lower ends are respectively installed in the foundation pit 2 below the ground. The middle section of the wind-load linkage mechanism extends to the left and right sides respectively and is respectively connected to the middle section of the lattice column assembly at the corresponding position.

[0056] After installation and construction, the lattice column steel structure system of the present invention forms a system in which both ends are stably supported by lattice column assemblies, and the middle part relies on the large-span steel structure beam group 1 as the upper bearing member, which can effectively ensure the stability and firmness of the support. At the same time, a wind load linkage mechanism is added at the bottom of the middle section of the large-span steel structure beam group 1 to adapt to the application in engineering environments in remote outdoor areas with relatively severe wind loads. The entire wind load linkage mechanism can play the role of buffering and offsetting the load by relying on damping when the system is subjected to wind load. At the same time, the entire wind load linkage mechanism is connected to the fixed linkage members of the lattice column assembly at the corresponding positions on both sides during operation. It can be linked to the integrated pre-assembled parts inside the inner cavity of the vertical lattice column 3 of the corresponding lattice column assembly according to the changes in the upper and lower positions of the upper large-span steel structure beam group 1 when subjected to load changes to achieve buffering and lifting adjustment, thereby driving the corresponding fixed linkage member to achieve follow-up lifting, so that after the fixed linkage member is lifted and lowered, the end of the tie wire rope 23 on the wind load linkage mechanism connected to it is driven to appropriately lift and lower, thereby achieving the effect of matching and buffering.

[0060] The top height adjustment support installed in the cavity of the vertical lattice column 3 can adjust its height in advance or during the later maintenance process as needed to adjust the position of the fixed linkage part on its top and control the tightening force of the lower spring 12 at the corresponding position to cope with different wind loads and variable loads under later working conditions.

[0066] When working, the wind-load linkage mechanism mainly relies on the corresponding two tie-knotted steel wire ropes 23 to connect the damping buffer assembly at the bottom with the fixed linkage parts on both sides. When connecting, it can be reversed by bypassing the upper pulley reversing group 22. At the same time, it can realize the downward pulling of the middle bottom of the large-span steel structure beam group 1, effectively matching the fixed linkage parts on both sides to achieve multi-point positioning and downward pulling of the entire large-span steel structure beam group 1, thereby ensuring the stability of the entire large-span steel structure beam group 1 structure.

[0067] In any of the above schemes, it is preferred that the damping and buffering assembly includes a protective box 25 fixedly installed in the foundation pit 2 below the ground, and two lower wire rope reversing pulley groups 26 are symmetrically installed at intervals inside the protective box 25. The lower end of each of the tie wire ropes 23 extends from the through hole at the top of the protective box 25 to the inner cavity of the protective box 25. The lower end of each of the tie wire ropes 23 passes through the lower wire rope reversing pulley group 26 at the corresponding position and is converted into a horizontal shape and is fixedly connected to the output end of the horizontal damper 27 fixed at the corresponding position. Each of the horizontal dampers 27 is fixed relative to the ground.

[0068] After the damping buffer assembly is fixed, it can be fixedly tied to the tie wire rope 23 that is reversed to a horizontal state through the corresponding lower reversing pulley assembly 26 of the wire rope, thereby achieving the purpose of linking the tie wire rope 23 with the horizontal damper 27.

[0069] In any of the above solutions, preferably, a linkage locking mechanism is further installed on the upper part of the two tie wire ropes 23.

[0070] The interlocking locking mechanism includes two main pipe sleeves 28 respectively sleeved on the vertical sections of the tie wire rope 23 at corresponding positions, and the two main pipe sleeves 28 are tied and fixed by a connecting spring 29. A secondary pipe sleeve 30 is sleeved on the outer side wall of the inclined section of the tie wire rope 23 on one side of each main pipe sleeve 28, and a short-connecting steel wire rope 31 is fixedly connected to the outer side walls of the relatively arranged main pipe sleeve 28 and the secondary pipe sleeve 30, respectively. A short-connecting stud 32 and a short-connecting screw 33 are fixedly connected to the opposite ends of the two short-connecting steel wire ropes 31, respectively. The short-connecting stud 32 and the short-connecting screw 33 are fixedly connected by threaded engagement, and the main pipe sleeve 28 and the secondary pipe sleeve 30 are controlled by controlling the amplitude of the engagement of the short-connecting stud 32 and the short-connecting screw 33 to achieve tensioning of the inclined section and the vertical section of the same tie wire rope 23.

[0071] During installation, the interlocking locking mechanism mainly relies on controlling the amplitude of the screwing of the short-connecting stud 32 and the short-connecting screw 33 to control the main sleeve 28 and the auxiliary sleeve 30 to achieve the degree of tensioning of the inclined section and the vertical section of the same tie wire rope 23, thereby ensuring the firmness of the connection between the corresponding inclined section and the vertical section of the same tie wire rope 23, and playing the role of self-locking the same tie wire rope 23. The tie wire rope 23 after self-locking can be used as a tensioning tie member, and adjusting the tensioning force can control the comprehensive effect of the damping buffer and the spring buffer on both sides.

[0072] The present invention further provides an installation process for a lattice column steel structure system, wherein the lattice column steel structure system is the above-mentioned lattice column steel structure system, and the installation process for the lattice column steel structure system comprises the following steps:

[0073] Prepare construction components and transport them to the construction site;

[0074] Harden the ground at the construction site and excavate foundation pit 2;

[0075] Hoist two vertical lattice columns 3 and pre-embed their bottoms, and fix them in place by pouring concrete; ensure the firmness of the vertical lattice columns 3 during installation;

[0076] A temporary opening is provided on the side wall of the lower side of each vertical lattice column 3 for installing a top height adjustment support member. The top height adjustment support member is fixedly installed at the bottom of the inner cavity of the vertical lattice column 3 through the temporary opening. After adjustment, the temporary opening can be welded and sealed to achieve closed control.

[0077] After the construction is completed, the temporary opening will be sealed with iron plates to prevent non-staff from performing arbitrary operations;

[0078] During aerial work, the top of each vertical lattice column 3 is used to sequentially install the integrated pre-assembled component consisting of the load-bearing column 5, upper shock absorber 8, load-bearing seat 6, lifting seat 9, upper pressure seat 10, upper spring 11, and lower spring 12 into the cavity of the vertical lattice column 3, and its bottom is supported on the top of the corresponding top height adjustment support member; pre-assembling the integrated pre-assembled component and then installing it in an integrated manner can effectively improve the operation efficiency and reduce the difficulty of operation;

[0079] The entire integrated pre-assembled component can be adjusted to a suitable height by screwing and adjusting the height of the top height adjustment support member;

[0080] After the height of the integrated pre-assembled part is adjusted, the fixed linkage part is installed on the side wall of the lifting seat 9 at the through-opening long slot 13;

[0081] After the two lattice column assemblies are installed, the long-span steel structure beam group 1 is hoisted and supported and fixed on the top of the two lattice column assemblies by hoisting equipment. At the same time, the middle positioning top seat 21 and two upper pulley reversing groups 22 are pre-fixed in the middle of the long-span steel structure beam group 1.

[0082] Install the fixed damping and buffering components inside the foundation pit 2. After the damping and buffering components are fixed and installed, continue to install the wind load linkage mechanism;

[0083] When installing the wind-load linkage mechanism, the lower ends of the two tie wire ropes 23 are fixedly installed on the output ends of the corresponding horizontal dampers 27, and the upper ends are passed around the upper pulley reversing group 22 and fixedly connected to the fixed linkage parts on the corresponding side.

[0084] After installation and construction, the lattice column steel structure system of the present invention forms a system in which both ends are stably supported by lattice column assemblies, and the middle part relies on the large-span steel structure beam group 1 as the upper bearing member, which can effectively ensure the stability and firmness of the support. At the same time, a wind load linkage mechanism is added at the bottom of the middle section of the large-span steel structure beam group 1 to adapt to the application in engineering environments in remote outdoor areas with relatively severe wind loads. The entire wind load linkage mechanism can play the role of buffering and offsetting the load by relying on damping when the system is subjected to wind load. At the same time, the entire wind load linkage mechanism is connected to the fixed linkage members of the lattice column assembly at the corresponding positions on both sides during operation. It can be linked to the integrated pre-assembled parts inside the inner cavity of the vertical lattice column 3 of the corresponding lattice column assembly according to the changes in the upper and lower positions of the upper large-span steel structure beam group 1 when subjected to load changes to achieve buffering and lifting adjustment, thereby driving the corresponding fixed linkage member to achieve follow-up lifting, so that after the fixed linkage member is lifted and lowered, the end of the tie wire rope 23 on the wind load linkage mechanism connected to it is driven to appropriately lift and lower, thereby achieving the effect of matching and buffering.

[0085] The overall support of the vertical lattice column 3 is relatively strong. A load-bearing column 5 is inserted in the top cavity of the vertical lattice column 3. Relying on the supporting effect of the load-bearing seat 6 on the top of the load-bearing column 5, effective support for the large-span steel structure beam group 1 can be achieved to ensure its support effect; the upper shock absorber 8 provided can adopt rubber shock absorption or spring shock absorption, which mainly serves the purpose of coping with wind loads and realizing that the entire large-span steel structure beam group 1 can be controlled to move within a certain height range. At the same time, relying on the load-bearing column 5, the circumferential direction can be limited to ensure the verticality of the large-span steel structure beam group 1.

[0086] The top height adjustment support installed in the cavity of the vertical lattice column 3 can adjust its height in advance or during the later maintenance process as needed to adjust the position of the fixed linkage part on its top and control the tightening force of the lower spring 12 at the corresponding position to cope with different wind loads and variable loads under later working conditions.

[0087] The column support of this steel structure system adopts vertical lattice columns 3 to effectively ensure its overall supporting strength. At the same time, a wind load linkage mechanism for resisting wind load and variable load is set between the two vertical lattice columns 3, which can better ensure the support while effectively resisting the role of balancing wind load in outdoor strong wind areas, thereby ensuring the stability of the entire system; the main body of the wind load linkage mechanism adopts tie wire ropes 23 to realize multiple linkage of the vertical lattice columns 3 on both sides, the large-span steel structure beam group 1 at the top and the ground, effectively offsetting or weakening the variable load generated by wind load by each component in the entire system to achieve damping and spring buffering, effectively reducing the impact of variable load on the rigidity strength of the system, and improving the stability of the system when responding to variable load; in addition, the wind load linkage mechanism of the entire system is also equipped with a corresponding linkage locking mechanism. By pre-installing and setting the locking degree of the linkage locking mechanism, the locking angle of each tie wire rope 23 can be controlled during pre-installation, ensuring the locking effect of the entire wind load linkage mechanism after installation, while allowing it to have a certain buffering amplitude, and at the same time playing a locking and locking protection effect when the amplitude is too large.
