Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal roof steel frame construction in general building construction, in particular to a damping structure of a metal roof steel frame construction. BACKGROUND

[0002] Metal roof steel frame construction generally refers to a framework structure constructed by steel structure materials, and a roof made of metal materials laid on the top of the framework structure. Because the metal roof has the characteristics of high strength, good durability and stable performance, and the steel structure framework structure has the advantages of fast installation speed and high structural strength, the metal roof steel frame construction is more and more widely used in building structures.

[0003] At present, in the metal roof steel frame construction, the connection between the metal roof and the steel structure framework is generally fixed by high-strength bolts. Although it can improve the overall stability of the structure, it is a rigid connection without damping structure, and the overall cooperation is weak. In extreme cases such as earthquakes, the bolt connection is prone to damage, which has great safety hazards.

[0004] In addition, a small part of metal roof steel frame construction designs have damping structures, but the damping form is relatively single, and the damping effect still needs to be improved. For example, the Chinese patent document with publication number CN220336256U discloses a factory roof structure, which includes a vertical rod, a cross beam and a pre-buried base, the top end of the vertical rod is fixedly connected with the cross beam, and the bottom end of the vertical rod is installed at the top end of the pre-buried base. It also includes a metal roof panel, a reinforcing rib, a cross frame, a damping connection assembly, a support assembly and a reinforcing assembly. The damping connection assembly includes a plurality of damping rods and a plurality of damping springs, the support assembly includes two inclined support beams, a vertical frame, a plurality of purlins and a plurality of positioning pins, the reinforcing rib is installed between the bottom end of the cross beam and the side wall of the vertical rod, supporting the cross beam, the cross frame is installed at the top end of the cross beam through the damping connection assembly, the support assembly is installed at the top end of the cross frame, and the reinforcing assembly is installed between two adjacent support assemblies. The metal roof panel is connected to the support assembly. The damping spring in the above-mentioned scheme can only play a vertical damping role and cannot play a horizontal damping role, and the overall damping effect needs to be further improved. SUMMARY

DETAILED DESCRIPTION

[0027] The application will be further described below in combination with the drawings and embodiments.

[0028] As Figures 1 to 16 shown, the application includes steel structure column 1, steel structure beam 2, arched upper suspension rod 3 and metal roof panel 4, the steel structure column 1 is arranged into two rows and symmetrically installed on the ground, the steel structure beam 2 is provided with a plurality of parallel ones, the left and right ends of each steel structure beam 2 are installed at the top ends of the two symmetric steel structure columns 1; that is, the axis of the steel structure beam 2 is arranged along the left and right directions, the plurality of steel structure beams 2 are arranged along the front and back directions, and each row of steel structure columns 1 is also arranged along the front and back directions.

[0029] The arc-shaped upper suspension rod 3 is provided with a plurality of arc-shaped upper suspension rods 3 corresponding to the steel structure cross beams 2 one by one, the middle part of the arc-shaped upper suspension rod 3 is located above the steel structure cross beam 2, the two ends of the arc-shaped upper suspension rod 3 in the length direction correspond to pass through the suspension rod through hole 23 arranged at the two ends of the steel structure cross beam 2 respectively, and the two ends of the arc-shaped upper suspension rod 3 in the length direction are connected with the inner sides of the two steel structure columns 1 through the straight hole bolt limiting assembly respectively; the left and right ends of the steel structure cross beam 2 are installed at the top end of the steel structure column 1 through the arc hole bolt spring limiting assembly respectively. The "inner side of the steel structure column 1" refers to the side of the two symmetrical steel structure columns 1 facing each other.

[0030] The arc hole bolt spring limiting assembly comprises a column circular arc hole 13, a beam column limiting bolt 14 and a beam column limiting spring 15. The column circular arc hole 13 is arranged at the top end of the steel structure column 1. The axis of the beam column limiting bolt 14 and the central axis of the column circular arc hole 13 are both arranged horizontally in the front-rear direction. The central axis of the column circular arc hole 13 refers to the central axis of the cylindrical surface corresponding to the upper arc wall (or lower arc wall) of the column circular arc hole 13. The middle part of each column circular arc hole 13 is lower than the left and right end parts. The beam column limiting bolt 14 passes through the column circular arc hole 13 and the bolt hole on the steel structure beam 2 to connect the steel structure column 1 and the steel structure beam 2 together. The beam column limiting bolt 14 can adopt a conventional fixed bolt head matched with a nut to play an axial limiting role, or can be provided with a nut at each end of the beam column limiting bolt 14 to play an axial limiting role. The beam column limiting bolt 14 can reciprocate along the column circular arc hole 13. The upper end of the beam column limiting spring 15 is connected to the beam column limiting bolt 14, and the lower end is connected to the steel structure column 1. The two ends of the beam column limiting spring 15 can be directly connected or indirectly connected to the above-mentioned connecting points. For example, in some preferred embodiments described below, the lower end of the beam column limiting spring 15 is connected to the wallboard fixing bolt 52 through a sleeve ring 16. When the beam column limiting bolt 14 is located at the lowest point of the column circular arc hole 13, the steel structure beam 2 is placed horizontally on the top end of the steel structure column 1. That is, under the conventional condition, the steel structure beam 2 is provided with vertical support force by the top end of the steel structure column 1. When the steel structure beam 2 is subjected to external force, it will produce a certain displacement trend in the left-right direction, so that the beam column limiting bolt 14 moves left and right in the column circular arc hole 13, and converts the external force into gravitational potential energy. Then, under the joint action of its own gravity and the elastic tension of the beam column limiting spring 15, the steel structure beam 2 will gradually recover to the original position. The steel structure beam 2 is installed at the top end of the two symmetrical steel structure columns 1 through the arc hole bolt spring limiting assembly, and the arc hole bolt spring limiting assembly is used to limit and fix the steel structure beam 2 and the steel structure column 1. In extreme cases such as earthquakes, the steel structure beam 2 is used to dissipate energy through displacement in a certain direction, and the automatic correction of the position deviation is realized. The steel structure beam 2 reciprocates along the arc track of the column circular arc hole 13 with the beam column limiting bolt 14, which can buffer the horizontal vibration and the vertical vibration at the same time.

[0031] The straight-hole bolt limiting assembly comprises a column vertical hole 11, a column limiting bolt 31, a column bolt limiting spring one 34, and a column bolt limiting spring two 55. The column vertical hole 11 is a strip-shaped hole extending in the vertical direction (for the up-and-down movement of the column limiting bolt 31), and is arranged on the steel structure column 1. The axis of the column limiting bolt 31 is horizontally arranged in the front-and-back direction. The column limiting bolt 31 passes through the column vertical hole 11 and the bolt hole on the arched upper suspension rod 3 to connect the steel structure column 1 and the arched upper suspension rod 3 together. The column limiting bolt 31 can reciprocate along the column vertical hole 11. The lower end of the column bolt limiting spring one 34 is connected to the steel structure column 1, and the upper end is connected to the column limiting bolt 31. The upper end of the column bolt limiting spring two 55 is connected to the steel structure column 1, and the lower end is connected to the end of the arched upper suspension rod 3. The two ends of the column bolt limiting spring one 34 can be directly or indirectly connected to the above-mentioned connecting points. For example, in some preferred embodiments described below, the upper end of the column bolt limiting spring two 55 is connected to the wall plate fixing bolt 52 through the sleeve ring two 53 and the fixed cylinder 54. The lower end of the column bolt limiting spring one 34 is connected to the end of the column fixing bolt 121. The end of the arched upper suspension rod 3 can move up and down with the column limiting bolt 31. When subjected to external forces such as earthquakes, the arched upper suspension rod 3 converts its kinetic energy into its gravitational potential energy by rising at the end position, and returns to its original position under the joint action of its own gravity, the column bolt limiting spring one 34, and the limiting spring two 55, thereby improving the damping effect.

[0032] The metal roof panel 4 is installed on the arched upper suspension rod 3 and the steel structure beam 2 through the elastic universal assembly. The elastic universal assembly can have various implementation forms, and at least comprises an elastic connecting piece and a universal adjusting piece. The elastic connecting piece is used to buffer and dampen, and the universal adjusting piece is used to enable the metal roof panel 4 to relatively displace with respect to the arched upper suspension rod 3 and the steel structure beam 2.

[0033] In some preferred schemes, the application further comprises a metal side wall panel 5. In order to improve the damping performance of the metal side wall panel installation structure, the preferred installation scheme is as follows: the metal side wall panel 5 is arranged outside the two rows of steel structure columns 1, and the elastic damping piece 51 is arranged between the metal side wall panel 5 and the steel structure column 1. The metal side wall panel 5, the elastic damping piece 51, and the steel structure column 1 are sequentially penetrated by the wall plate fixing bolt 52 in the left-and-right direction and are fixed by the fixed nut. The "outside of the two rows of steel structure columns 1" refers to the side farthest from each other of the two rows of steel structure columns 1. In extreme cases such as earthquakes, when the metal side wall panel 5 is subjected to external pressure, the elastic damping piece 51 can be deformed and compressed, and can dampen the metal side wall panel 5.

[0034] To further improve the overall structural reliability of the building, in the further preferred embodiments of the above preferred scheme, the lower end of the beam-column limiting spring 15 is connected to the inner end of one of the wall plate fixing bolts 52. The "inner end of the wall plate fixing bolt 52" refers to the end of the wall plate fixing bolt 52 located inside the steel structure column 1. When the metal side wall plate 5 is subjected to external pressure, such as strong wind, the elastic shock absorbing member 51 can be compressed, the wall plate fixing bolt 52 is elongated and the beam-column limiting spring 15 is stretched, thereby making it more difficult for the beam-column limiting bolt 14 to displace, improving the stability of the steel structure beam 2. Similarly, the lower end of the rod-column bolt limiting spring one 34 or the upper end of the rod-column bolt limiting spring two 55 is connected to the inner end of one of the wall plate fixing bolts 52. In the preferred embodiments shown in the drawings, the upper end of the rod-column bolt limiting spring two 55 is connected to the inner end of one of the wall plate fixing bolts 52. The beam-column limiting spring 15 and the rod-column bolt limiting spring two 55 are usually connected to different wall plate fixing bolts 52.

[0040] To further improve the overall structural reliability and shock absorption performance of the building, in some preferred embodiments, the upper end of the metal roof panel 4 is located above the middle region of the arched upper suspension rod 3, the lower end of the metal roof panel 4 is respectively arranged at the left end and the right end of the steel structure beam 2, the elastic universal assembly includes a first elastic universal assembly 7 and a second elastic universal assembly 8, the lower end of the metal roof panel 4 is installed on the steel structure beam 2 through the first elastic universal assembly 7, and the upper end and the middle part of the metal roof panel 4 are respectively installed on the arched upper suspension rod 3 and the steel structure beam 2 through the second elastic universal assembly 8. To facilitate assembly, the metal roof panel 4 is usually provided as two groups of left-right symmetrical distribution, and the upper ends of the two groups of metal roof panels 4 are connected through a roof connecting assembly. The middle part of the metal roof panel 4 refers to the intermediate region between the upper end and the lower end of the metal roof panel 4. In some alternative embodiments, the upper end and the middle part of the metal roof panel 4 can also be respectively installed on the arched upper suspension rod 3 through the first elastic universal assembly 7.

[0041] The first elastic universal component 7 comprises a plurality of disc springs 71, longitudinal steel structure lower beams 72 and universal rotating hangers 73, which are arranged at the ends of the steel structure cross beams 2.

The longitudinal steel structure lower beams 72 or the metal roof panels 4 have accommodating grooves matched with the universal rotating hangers 73, so that the lower ends of the metal roof panels 4 are attached to the upper end faces of the longitudinal steel structure lower beams 72. In order to facilitate assembly and effectively ensure the structural reliability, the lower ends of the metal roof panels 4 can be additionally provided with U-shaped bolts 41 for connecting the universal rotating hangers 73. The U-shaped bolts 41 are existing complete components, which generally comprise a U-shaped connecting piece and nuts at both ends of the U-shaped connecting piece. In some alternative embodiments, the universal rotating hangers 73 can also be connected through a lock catch structure and a fixed connecting ring at the lower ends of the metal roof panels 4. The lower ends of the metal roof panels 4 can be directly attached to the upper end faces of the longitudinal steel structure lower beams 72, or longitudinal steel structure upper beams 43 can be additionally arranged at the lower ends of the metal roof panels 4, and the longitudinal steel structure upper beams 43 are attached to the upper end faces of the longitudinal steel structure lower beams 72. Correspondingly, the accommodating grooves matched with the universal rotating hangers 73 can also be arranged on the lower surfaces of the longitudinal steel structure upper beams 43. The accommodating grooves can be continuous longitudinal groove structures or spaced blind hole structures. The accommodating grooves are used to hide the universal rotating hangers 73 and the connecting members at both ends thereof, so as not to affect the support of the longitudinal steel structure lower beams 72 on the metal roof panels 4 or the longitudinal steel structure upper beams 43. When the lower ends of the metal roof panels 4 and the ends of the steel structure cross beams 2 are shaken and deviated due to external forces, the universal rotating hangers 73 can generate a restraining force within a certain range and play a limiting role.

[0042] The second elastic universal assembly 8 comprises a longitudinal steel structure middle beam 81, a roof limiting bolt 82, a roof limiting nut 83, a universal rotating ring two 84, a ring limiting spring 85, a disc spring two 86, a longitudinal steel structure lower beam two 87 and a universal rotating ring three 88. The longitudinal steel structure middle beam 81 is arranged between the upper side of the arched upper suspension rod 3 and the metal roof panel 4, and extends along the front-rear direction. The metal roof panel 4 is fixedly installed on the longitudinal steel structure middle beam 81, and at least part of the longitudinal steel structure middle beam 81 is in contact with the arched upper suspension rod 3. The upper end of the roof limiting bolt 82 is fixedly installed in the longitudinal steel structure middle beam 81, and the lower end penetrates through the avoidance hole of the arched upper suspension rod 3. The roof limiting nut 83 is sleeved and fixed on the roof limiting bolt 82 below the arched upper suspension rod 3. The connecting position of the roof limiting nut 83 allows the arched upper suspension rod 3 to have a displacement space on the roof limiting bolt 82. The upper end of the universal rotating ring two 84 is fixedly installed at the lower end of the roof limiting bolt 82, and the lower end is fixedly connected to the upper end of the ring limiting spring 85. The disc spring two 86 and the universal rotating ring three 88 are arranged in the middle part of the steel structure beam 2. The disc spring two 86 is fixedly installed on the transverse steel plate 22 of the steel structure beam 2, and the top end is higher than the two longitudinal steel plates 21.

The lower end of the universal rotating ring three 88 is fixedly installed on the longitudinal steel structure lower beam two 87, and the upper end is fixedly connected to the lower end of the ring limiting spring 85.

[0043] In general, the upper end and the middle part of the metal roof panel 4 and the longitudinal steel structure middle beam 81 are placed on the arched upper suspension rod 3 under the action of its own gravity, and the arched upper suspension rod 3 provides support for the metal roof panel 4 and the longitudinal steel structure middle beam 81. However, due to the installation precision, deformation or vibration of the arched upper suspension rod 3, not all arched upper suspension rods 3 provide support for the metal roof panel 4 and the longitudinal steel structure middle beam 81. At the same time, the upper end of the roof limiting bolt 82 is fixedly installed in the longitudinal steel structure middle beam 81, and the lower end penetrates through the arched upper suspension rod 3. The roof limiting nut 83 does not lock the longitudinal steel structure middle beam 81 and the arched upper suspension rod 3, so that the arched upper suspension rod 3 has a certain displacement space on the roof limiting bolt 82. When individual or partial arched upper suspension rods 3 vibrate and displace, the overall stability of the metal roof panel 4 and the longitudinal steel structure middle beam 81 is not affected.

[0044] For the convenience of assembly, and further enhance the overall structural reliability of the building, in some preferred embodiments, the universal rotating ring one 73, the universal rotating ring two 84 and the universal rotating ring three 88 all include a cylindrical ring base 731, a base cover plate 732, a ring bolt 733, a base ring 734 and a connecting ring 735, the axial one end of the cylindrical ring base 731 is a closed end, the other end is an open end, the base ring 734 is fixedly installed outside the closed end of the cylindrical ring base 731, the base cover plate 732 is fixed on the open end of the cylindrical ring base 731 through screws, the ring bolt 733 penetrates the bolt hole provided on the base cover plate 732 and the end part 736 of the ring bolt 733 inside the cylindrical ring base 731 is fixedly provided with a bolt end part 736, the bolt end part 736 is rotatably connected with the base cover plate 732 through a plurality of balls 737, and the rotation axis is coaxial with the ring bolt 733. The balls 737 are installed in the annular grooves provided on the bolt end part 736 and the base cover plate 732. That is, the main body structure of the universal rotating ring one 73, the universal rotating ring two 84 and the universal rotating ring three 88 is the same, and all includes the above-mentioned cylindrical ring base 731, base cover plate 732, ring bolt 733, base ring 734, connecting ring 735, bolt end part 736 and ball 737. The bolt end part 736 can usually adopt a disc structure, or a spherical arc end face can be added to the upper surface of the disc structure, and the ring bolt 733 and the bolt end part 736 can be designed as an integral structure.

[0045] The difference lies in that the universal rotating ring one 73 and the universal rotating ring three 88 both further include a tightening member 738, the tightening member 738 is fixedly sleeved on the ring bolt 733 outside the base cover plate 732; the outer end of the ring bolt 733 in the universal rotating ring one 73 is connected and fixed with the threaded hole on the longitudinal steel structure lower beam one 72 through the external thread structure, and the end of the connecting ring 735 in the universal rotating ring one 73 away from the cylindrical ring base 731 is connected with the lower end of the metal roof panel 4; the outer end of the ring bolt 733 in the universal rotating ring three 88 is connected and fixed with the threaded hole on the longitudinal steel structure lower beam two 87 through the external thread structure, and the end of the connecting ring 735 in the universal rotating ring three 88 away from the cylindrical ring base 731 is connected with the lower end of the ring limiting spring 85. By rotating the tightening member 738 with a wrench, the rotation of the ring bolt 733 can be realized, which facilitates the butt joint of the ring bolt 733 and the longitudinal steel structure lower beam one 72 and the longitudinal steel structure lower beam two 87, thereby facilitating the overall installation of the universal rotating ring one 73 and the universal rotating ring three 88.

[0046] The universal rotating lifting ring 84 also includes a sleeve 841, one axial end of which is a closed end and the other end is an open end. The outer side of the closed end of the sleeve 841 is fixed to the end of the lifting ring bolt 733 on the outer side of the base cover plate 732. The inner wall of the open end of the sleeve 841 is provided with an internal thread, which is connected to the external thread provided at the lower end of the roof limiting bolt 82. The connecting lifting ring 735 in the universal rotating lifting ring 84 is connected to the upper end of the lifting ring limiting spring 85 at the end away from the cylindrical lifting ring base 731.

[0047] To further enhance the overall structural reliability of the building, in some preferred embodiments, a downwardly extending vertical limiting plate 42 is fixedly installed at the end of the metal roof panel 4. The inner side of the vertical limiting plate 42 forms a clearance fit with the left and right end faces of the steel structure beam 2, respectively. The vertical limiting plate 42 can limit the displacement of the metal roof panel 4 relative to the steel structure beam 2 in the left and right directions.

[0048] The present invention uses a first elastic universal joint 7 and U-bolts 41 to fix the lower end of the metal roof panel 4 to the end of the steel structure beam 2, and uses a second elastic universal joint 8 to connect the upper end and middle part of the metal roof panel 4 to the arched upper suspension rod 3 and the steel structure beam 2, thereby reducing the impact of the displacement of a single steel structure beam 2 and arched upper suspension rod 3 on the overall stability of the metal roof panel 4 and improving the stability of the metal roof panel 4.

[0049] The present invention has a compact structure. By setting up multiple elastic damping structures, it facilitates the dissipation of kinetic energy of the steel structure beam 2, the arched upper suspension rod 3 and the metal roof panel 4 under extreme conditions such as earthquakes, thereby improving the overall coordination, seismic resistance, stability and connection strength.
