Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and specifically relates to a steel structure base for factory buildings. The steel structure base is particularly suitable for use in the process of connecting steel columns of industrial steel structure factories with concrete foundations, and the errors generated during the construction process are adjusted through the steel structure base. Background Art

[0002] Industrial plants refer to various houses that are directly used for production or supporting production, including main workshops, auxiliary rooms and ancillary facilities. The construction of industrial plants is similar to the construction principle of general reinforced concrete buildings. They all need to first construct the foundation underground, then fill it with backfill soil, bury the foundation underground, and then build the upper structure. At present, the base and superstructure structure of industrial plants are mostly built with a large amount of steel. Among them, the steel structure base, as the base of the factory, is usually pre-cast in the cup foundation in a matrix form, and the part of the steel structure base used to connect with the superstructure structure is extended out of the ground, and the superstructure structure may include steel structure pillars and steel structure walls used to support the plant.

[0003] In the process of burying the steel structure base in the foundation pit, on the one hand, after the steel structure base is buried, it is necessary to fill the soil. Therefore, the steel structure base body should not hinder the filling work. On the other hand, there are certain height errors in the depths of different foundation pits. In order to ensure that the upper connection position of the steel structure base remains parallel to the design elevation of the column bottom, the steel structure base needs to have a certain adjustment function.

[0004] Patent document CN212956597U proposes a steel structure base for factory buildings, including three groups of through holes on the front and rear sides of the bottom plate, and pins are movably arranged inside the three groups of through holes. A push plate is arranged on the upper surface of one side of the pin, and the six push plates are symmetrically arranged about the center line of the upper surface of the bottom plate. Three groups of protective shells are arranged between the three groups of symmetrically arranged push plates and on the upper surface of the bottom plate. The central positions of the three groups of push plates are all provided with threaded rods, and the threaded rods longitudinally penetrate the interior of the protective shells. The same transmission rod is arranged inside the three groups of protective shells, and connecting plates are arranged on both sides of the upper surface of the bottom plate, and a tamping plate is arranged above the connecting plates. The steel structure base for factory buildings can improve the stability of the steel structure base during installation and prevent the installation position from being offset. In addition, it can reduce the shaking of the factory wall in bad weather and improve the stability of the connection between the wall and the steel structure base. However, the steel structure base body for factory buildings proposed in patent document CN212956597U has problems of hindering filling and pouring during the process of being buried in the foundation pit, and the steel structure base lacks adjustment function. Therefore, it is urgent to develop a steel structure base for factory buildings that is easy to pour into the cup mouth, easy to adjust, and has high stability. Summary of the invention

DETAILED DESCRIPTION

[0024] In order to further describe the present invention, a steel structure base for an industrial steel structure plant building of the present invention is described in more detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Depend on Figure 1 The front view cross-sectional structure diagram of a steel structure base for an industrial steel structure factory building of the present invention is shown in combination with Figure 2 , Figure 3 , Figure 5 It can be seen that the steel structure base for an industrial steel structure factory building of the present invention includes a bottom plate 1 horizontally arranged in a foundation pit, a rectangular sleeve 2 arranged vertically upward is fixedly connected to the middle of the upper plate surface of the bottom plate 1, and a telescopic column 3 is slidably connected inside the rectangular sleeve 2. By setting the telescopic column 3 and setting the outer surface of the telescopic column 3 to a rectangle, the surface width of the telescopic column 3 is equal to the inner wall width of the rectangular sleeve 2, so that the telescopic column 3 can move up and down in the rectangular sleeve 2; a mounting plate 4 is fixedly connected to the upper end of the telescopic column 3, and a plurality of vertically symmetrically arranged bolt heads 5 are fixedly connected to the upper end of the mounting plate 4. By setting the mounting plate 4 and the bolt heads 5, when in use, the mounting plate 4 is in contact with the ground, and the bolt heads 5 are used to connect the present invention to other components in the factory building.

[0026] Depend on Figure 7 shown Figure 1 The enlarged structural diagram of A in the middle is combined with Figure 1 , Figure 2 , Figure 4 , Figure 6It can be seen that a limiting mechanism for limiting its own height position is provided inside the lower end of the telescopic column 3, and the limiting mechanism includes a cylindrical groove 6 provided inside the lower end of the telescopic column 3, and two symmetrically arranged latches 7 are slidably connected in the cylindrical groove 6, and a spring 8 is fixedly connected between the two latches 7. By setting the spring 8, under the condition of no external force, the spring 8 keeps pushing the two latches 7 away from each other, so that the latch 7 maintains the tendency to move out of the cylindrical groove 6; a circular plate 9 is rotatably connected inside the lower end of the telescopic column 3 and located on the upper side of the cylindrical groove 6, and a lever 10 arranged vertically upward is fixedly connected to the upper end of the latch 7, and a sliding groove 11 matching the lever 10 is provided on the circular plate 9, and the upper end of the lever 10 is slidably connected to the sliding groove 11, and a cylindrical rod 12 arranged vertically upward and rotatably connected to the telescopic column 3 is coaxially fixedly connected to the upper end of the circular plate 9, and a knob 13 is fixedly connected to the upper end of the cylindrical rod 12, and a groove 14 is provided at the upper end of the mounting plate 4. The knob 13 It is embedded in the groove 14 and is set by the knob 13 embedded in the groove 14 without affecting other installation work on the upper surface of the subsequent mounting plate 4; by setting the lever 10 and the sliding groove 11, when the knob 13 is rotated, the knob 13 drives the circular plate 9 to rotate through the cylindrical rod 12, and the circular plate 9 drives the sliding groove 11 thereon to rotate, and the lever 10 can only move horizontally, so the sliding groove 11 will push the lever 10 to move with the help of its inner wall; further, the lever 10 drives the pin 7 to move in the cylindrical groove 6, and the inner wall of the rectangular sleeve 2 is provided with a plurality of limiting holes 15 matching the pin 7. The end of the pin 7 away from the spring 8 is horizontally slid and inserted into one of the limiting holes 15. By setting the limiting hole 15, when the pin 7 corresponds horizontally to one of the limiting holes 15, the pin 7 that maintains a tendency to move out of the cylindrical groove 6 can be inserted into the limiting hole 15, so that the telescopic column 3 cannot continue to move up and down in the rectangular sleeve 2.

[0027] Depend on Figure 1 The front view cross-sectional structure diagram of a steel structure base for an industrial steel structure factory building of the present invention is shown in combination with Figure 2 , Figure 4 , Figure 5It can be seen that a horizontally arranged pressure plate 16 is slidably sleeved on the outside of the rectangular sleeve 2, and a plurality of circumferentially symmetrically arranged hook rings 17 are fixedly connected to the upper end of the pressure plate 16. A plurality of circumferentially symmetrically arranged receiving grooves 18 are provided in the base plate 1, and an insertion rod 19 is slidably connected in the receiving groove 18. A plurality of circumferentially symmetrically arranged first connecting members 20 are fixedly connected to the lower end of the pressure plate 16 near the rectangular sleeve 2, and a second connecting member 22 is rotatably connected to the lower end of the first connecting member 20 through an inclined connecting rod 21. The lower end of the second connecting member 22 slides through the upper surface of the base plate 1 and is fixedly connected to the upper end of the insertion rod 19. The hook ring 17 is provided for lifting equipment to lift the steel structure base, and since the hook ring 17 is fixed on the pressure plate 16, during the process of the steel structure base being lifted, the pressure plate 16 moves upward away from the base plate 1, and then the insertion rod 19 is driven by the connecting rod 21 to remain in the receiving groove 18, thereby not hindering the base plate 1 from vertically entering the base.

[0028] Working principle: When the steel structure base needs to be buried in the cup mouth, first use the lifting equipment to hook the four hook rings 17 to keep the pressure plate 16 horizontal. At this time, under the action of gravity, the bottom plate 1 moves downward relative to the pressure plate 16, and the pressure plate 16 pulls the connecting rod 21, and the connecting rod 21 drives the insertion rod 19 to remain in the storage groove 18. Then the steel structure base is vertically aligned with the cup mouth and slowly lowered into the cup mouth. When the bottom plate 1 contacts the bottom surface of the foundation pit, the lifting equipment can release the hook ring 17. At this time, due to the obstruction of the inner wall of the foundation pit, the insertion rod 19 still remains in the storage groove 18.

[0029] Next, concrete is continuously poured into the cup mouth. Under the action of the downward pressure generated when pouring concrete, the pressure plate 16 is continuously pushed downward along the outer wall of the rectangular sleeve 2. Therefore, the pressure plate 16 drives the upper end of the connecting rod 21 downward through the first connecting member 20, so that the lower end of the connecting rod 21 pushes the second connecting member 22 in the direction away from the rectangular sleeve 2. The second connecting member 22 drives the insertion rod 19 to continuously extend out of the storage groove 18 and insert into the inner wall of the cup mouth, thereby strengthening the connection between the bottom plate 1 and the cup mouth.

[0030] When it is impossible to continue pouring concrete, the pressure plate 16 can no longer move downward, and then the knob 13 is turned, the knob 13 drives the cylindrical rod 12 to rotate, the cylindrical rod 12 drives the circular plate 9 to rotate, and the circular plate 9 drives the sliding groove 11 to rotate, so that the lever 10 and the sliding groove 11 move relative to each other, and the two levers 10 drive the two latches 7 to move into the cylindrical groove 6 and squeeze the spring 8. The spring 8 is elastically deformed and compressed by the force and stores elastic potential energy. When the latch 7 leaves the uppermost limit hole 15, the mounting plate 4 can be pushed downward, and the mounting plate 4 drives the extension The telescopic column 3 moves downward in the rectangular sleeve 2. When the mounting plate 4 moves downward to match the designed elevation, the latch 7 corresponds to another limit hole 15. The knob 13 is loosened, and the elastic potential energy of the spring 8 is released to push the latch 7 to move out of the cylindrical groove 6 and insert it into the corresponding limit hole 15 at this time, so that the telescopic column 3 is fixed to the rectangular sleeve 2. At the same time, the latch 7 drives the lever 10 to move, and the lever 10 moves in the sliding groove 11 and causes the circular plate 9 to rotate. The circular plate 9 drives the knob 13 to rotate to the initial position through the cylindrical rod 12, thereby completing the construction of the steel structure base.

[0031] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and range of equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
