Description

Technical Field

[0001] This utility model relates to the field of prefabricated steel structure building technology, specifically a prefabricated steel structure for building construction. Background Technology

[0002] Prefabricated steel structure buildings refer to prefabricated buildings whose structural system is composed of steel components. It is necessary for the steel structure, enclosure system, equipment and pipeline system and interior decoration system to be in harmony and unity. Columns are the supporting components of prefabricated steel structure buildings.

[0003] Chinese Patent No. 202320916967.9 discloses a prefabricated steel structure support column, including a mounting base and a main column. The main column is fixedly mounted on the top of the mounting base through a mounting positioning mechanism. The bottom of the main column is located in a mounting cavity opened at the top of the mounting base. Connecting components are fixedly mounted on the outside of the main column.

[0004] When this utility model is in use, the support column is prone to thermal expansion and contraction when the temperature changes significantly, which affects the stability of the support column. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated steel structure for building construction to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated steel structure for building construction, comprising a steel structure support; the steel structure support consists of a column, a mounting plate, and a mounting base; a shock-absorbing mechanism is mounted on the upper side of the mounting base; the upper end of the shock-absorbing mechanism is mounted on the bottom end of the mounting plate; a guide mechanism is installed between the mounting plate and the mounting base; a screw is mounted on the upper end of the mounting plate; a screw hole is provided at the bottom end of the column; a nut is installed on the outer side of the screw hole through the upper end of the screw; a filling cavity is provided inside the column; and the filling cavity is filled with a phase change material.

[0007] Preferably, the damping mechanism consists of a damping spring and a damper. The damper is installed at the bottom of the mounting plate and on the upper side of the mounting base, and the damping spring is installed at the bottom of the mounting plate and on the upper side of the mounting base, located outside the damper.

[0008] Preferably, a reinforcing strip is provided on the outer side of the support column, and the reinforcing strip is welded to the outer side of the support column.

[0009] Preferably, a heat-conducting plate is provided inside the packing cavity, and one end of the heat-conducting plate is welded to the inner wall of the support column.

[0010] Preferably, a hollow flexible tube is provided at the middle position of the packing cavity, and the hollow flexible tube is inserted into the packing cavity.

[0011] Preferably, a protective sleeve is provided between the mounting base and the mounting plate, and the protective sleeve is attached to the bottom of the mounting plate and the upper side of the mounting base with adhesive.

[0012] Preferably, the guiding mechanism consists of a through hole, a limiting plate, and a guide rod. The bottom end of the guide rod is mounted on the upper side of the mounting base, the through hole is located on the upper side of the mounting plate, the upper end of the guide rod is slidably mounted inside the through hole, and the limiting plate is mounted on the upper side of the guide rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The phase change material filled in the stuffing cavity inside the support column can undergo a phase change when the ambient temperature changes. When the temperature rises, the phase change material absorbs heat and changes from solid to liquid; when the temperature drops, it releases heat and changes from liquid to solid, thereby regulating the temperature of the support column, reducing the impact of temperature changes on the thermal expansion and contraction of the steel structure support, and improving the durability of the structure.

[0015] 2. One end of the heat-conducting plate inside the packing cavity is welded to the inner wall of the support column. Due to the good thermal conductivity of metal, when the support column experiences temperature fluctuations due to changes in the external ambient temperature, the heat-conducting plate can quickly transfer the heat from the inner wall of the support column to the phase change material inside the packing cavity, or transfer the heat released by the phase change material to the inner wall of the support column, thereby accelerating the heat exchange rate between the phase change material and the support column, improving the efficiency of the phase change material in regulating the temperature of the support column, and ensuring that the support column can maintain a relatively stable state when the temperature changes.

[0016] 3. The hollow flexible tube in the middle of the packing cavity is inserted into the packing cavity. It can provide a buffer space for the volume change of the phase change material during the phase change. When the phase change material changes from solid to liquid, the volume will expand. The hollow flexible tube can be squeezed and deformed to accommodate the expansion. When the phase change material changes from liquid to solid, the volume will shrink. The hollow flexible tube can return to its original shape, avoiding excessive internal stress on the packing cavity and support due to the volume change of the phase change material, and protecting the integrity of the support structure.

[0017] 4. When the guide mechanism is working, when the mounting plate is displaced by vibration or load, the upper end of the guide rod will slide inside the through hole of the mounting plate. Since the bottom end of the guide rod is fixed on the mounting base, the mounting plate is restricted to move up and down along the axis of the guide rod, thus realizing the guiding function. The limiting plate installed on the upper side of the guide rod can prevent the mounting plate from detaching from the guide rod during movement, ensuring the normal operation of the guide mechanism and guaranteeing the stability and safety of the relative movement between the mounting plate and the mounting base.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment of the utility model, a prefabricated steel structure for building includes a steel structure support 1; the steel structure support 1 consists of a column 4, a mounting plate 3 and a mounting base 2, a shock-absorbing mechanism 10 is installed on the upper side of the mounting base 2, the upper end of the shock-absorbing mechanism 10 is installed on the bottom end of the mounting plate 3, a guide mechanism 9 is installed between the mounting plate 3 and the mounting base 2, a screw 5 is installed on the upper end of the mounting plate 3, a screw hole is provided at the bottom end of the column 4, a nut 14 is installed on the outside of the screw hole at the upper end of the screw 5, a filling cavity 15 is provided inside the column 4, and the filling cavity 15 is filled with a phase change material 16.

[0026] The damping mechanism 10 consists of a damping spring 11 and a damper 12. The damper 12 is installed at the bottom of the mounting plate 3 and on the upper side of the mounting base 2. The damping spring 11 is installed at the bottom of the mounting plate 3 and on the upper side of the mounting base 2, located outside the damper 12. The damping mechanism 10 works together with the damping spring 11 and the damper 12 to perform the damping function. When the mounting plate 3 is subjected to vibration or external impact from the upper load, the damping spring 11 will first undergo elastic deformation, converting part of the impact energy into elastic potential energy for storage, thereby initially buffering the vibration. At the same time, the damper 12 will work with the relative movement between the mounting plate 3 and the mounting base 2. The damping medium inside the damper 12 will generate resistance, hindering the relative movement between the two, and dissipating the energy generated by the vibration through friction, damping, etc., avoiding continuous reciprocating vibration of the damping spring 11, so that the structure can quickly stabilize. The combination of the two greatly improves the damping effect of the steel structure support 1.

[0027] A reinforcing strip 19 is provided on the outside of the support column 4. The reinforcing strip 19 is welded to the outside of the support column 4 and fixed to the outside of the support column 4 by welding. Its operating principle is to use the high strength characteristics of the reinforcing strip 19 itself to increase the moment of inertia of the section of the support column 4, thereby improving the resistance of the support column 4 to deformation when subjected to loads such as axial pressure and lateral force. The welding connection method ensures a tight connection between the reinforcing strip 19 and the support column 4, so that the two can work together to resist external forces, effectively enhancing the overall structural strength and stability of the support column 4 and extending the service life of the support column 4.

[0028] A heat-conducting plate 18 is installed inside the packing cavity 15. One end of the heat-conducting plate 18 is welded to the inner wall of the support column 4. Since metal has good thermal conductivity, when the support column 4 experiences temperature fluctuations due to changes in the external ambient temperature, the heat-conducting plate 18 can quickly transfer the heat from the inner wall of the support column 4 to the phase change material 16 inside the packing cavity 15, or transfer the heat released by the phase change material 16 to the inner wall of the support column 4. This accelerates the heat exchange rate between the phase change material 16 and the support column 4, improves the efficiency of the phase change material 16 in regulating the temperature of the support column 4, and ensures that the support column 4 can maintain a relatively stable state when the temperature changes. A hollow flexible tube 17 is provided in the middle of the packing cavity 15. The hollow flexible tube 17 is inserted into the packing cavity 15. The hollow flexible tube 17 in the middle of the packing cavity 15 can provide a buffer space for the volume change of the phase change material 16 during the phase change. When the phase change material 16 changes from solid to liquid, its volume will expand. The hollow flexible tube 17 can be squeezed and deformed to accommodate the expansion. When the phase change material 16 changes from liquid to solid, its volume will shrink. The hollow flexible tube 17 can return to its original shape, avoiding excessive internal stress on the packing cavity 15 and the support column 4 due to the volume change of the phase change material 16, and protecting the integrity of the support column 4 structure.

[0029] A protective sleeve 13 is installed between the mounting base 2 and the mounting plate 3. The protective sleeve 13 is adhered to the bottom of the mounting plate 3 and the upper side of the mounting base 2 with adhesive. The protective sleeve 13 between the mounting base 2 and the mounting plate 3 is also adhered with adhesive, thus enclosing the damping mechanism 10 and the guide mechanism 9. Its operating principle is to prevent external dust, rainwater, impurities, etc. from entering the damping mechanism 10 and the guide mechanism 9, preventing these foreign objects from affecting the elastic performance and damping effect of the damping mechanism 10 and the smooth sliding of the guide mechanism 9. This protects the internal components, extends their service life, and ensures the normal operation of the structure.

[0030] The guiding mechanism 9 consists of a through hole 7, a limiting plate 6, and a guide rod 8. The bottom end of the guide rod 8 is mounted on the upper side of the mounting base 2. The through hole 7 is located on the upper side of the mounting plate 3. The upper end of the guide rod 8 is slidably mounted inside the through hole 7. The limiting plate 6 is mounted on the upper side of the guide rod 8. When the guiding mechanism 9 is working, if the mounting plate 3 is displaced due to vibration or load, the upper end of the guide rod 8 will slide inside the through hole 7 of the mounting plate 3. Since the bottom end of the guide rod 8 is fixed on the mounting base 2, this restricts the mounting plate 3 to move up and down only along the axis of the guide rod 8, thus realizing the guiding function. The limiting plate 6 mounted on the upper side of the guide rod 8 can prevent the mounting plate 3 from detaching from the guide rod 8 during movement, ensuring the normal operation of the guiding mechanism 9 and guaranteeing the stability and safety of the relative movement between the mounting plate 3 and the mounting base 2.

[0031] The working principle and usage process of this utility model: The steel structure support 1, as the core load-bearing and connecting component, consists of a column 4, a mounting plate 3, and a mounting base 2, forming a stable overall frame. The mounting base 2 is connected to the foundation or other building structure, providing a stable support foundation for the entire support. The mounting plate 3 is used to bear the upper building components or loads. The shock absorption mechanism 10 on the upper side of the mounting base 2 can effectively buffer and absorb the vibration and impact force transmitted from the outside. When vibration occurs, the shock absorption mechanism 10 will convert some of the kinetic energy into other forms of energy through its own deformation and damping action, reducing the vibration transmitted to the mounting plate 3 and the upper structure, thus playing a protective role. The guide mechanism between the mounting plate 3 and the mounting base 2... Structure 9 ensures that during vibration damping, the mounting plate 3 can only move along a specific direction, avoiding lateral offset or misalignment and ensuring structural stability. The screw 5 at the upper end of the mounting plate 3 engages with the screw hole at the bottom end of the support column 4, and the mounting plate 3 and support column 4 are detachably connected by tightening the nut 14, facilitating prefabricated construction. The phase change material 16 filled in the filling cavity 15 inside the support column 4 can undergo a phase change when the ambient temperature changes. When the temperature rises, the phase change material 16 absorbs heat and changes from solid to liquid; when the temperature drops, it releases heat and changes from liquid to solid, thereby regulating the temperature of the support column 4, reducing the impact of temperature changes on the thermal expansion and contraction of the steel structure support 1, and improving the durability of the structure.

[0032] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
