Description

Technical Field

[0001] This utility model belongs to the field of positioning tooling technology, specifically relating to a cup-shaped foundation steel structure column installation positioning device. Background Technology

[0002] Traditional building construction methods involve constructing the entire structure from bottom to top within the foundation pit. Specifically, this means first installing the foundation piles, then constructing the basement from the bottom up, and finally completing the above-ground structure. Another method is reverse construction, where, for example, the basement columns are constructed simultaneously or immediately after the foundation piles are completed, and then the basement beams and roof slab are installed later. Reverse construction is a method that can reduce foundation pit deformation, save costs, and shorten the construction period.

[0003] After the inverted floor slab is formed, the vertical structure needs to be constructed, typically using steel or concrete columns. If steel columns are used, the column heads need to be embedded during the construction of the inverted floor slab for subsequent connection to the steel columns. During the connection process, due to the influence of the inverted floor slab, large machinery cannot use a one-step hoisting method; the steel columns need to be installed in sections. When installing the intermediate steel structural columns, the intermediate steel structural columns and the lower steel structural columns below must maintain consistent verticality, and the connection accuracy between the column heads and the intermediate steel structural columns must be controlled. During installation, auxiliary equipment is typically required for positioning. For example, Chinese invention patent application number CN202410569418.8 discloses a multi-directional adjustment device and method for steel structure positioning. Specifically, it discloses an adjustable outer frame, positioned between the upper and lower steel structure columns, used to determine the position of the middle steel structure column, which can be embedded within the adjustable outer frame. The adjustable outer frame includes multiple fixedly connected mounting rods, with each pair of mounting rods forming a group, and the mounting rods in the same group being on the same straight line; a telescopic screw rod, installed between the mounting rods in the same group, used to adjust the distance between the mounting rods in the same group; and a jacking screw rod, installed on two groups of parallel mounting rods, with the jacking screw rod perpendicular to the mounting rods.

[0004] However, steel structure columns have a large self-weight. When using detachable auxiliary positioning devices such as snap-fit ​​devices, the contact between the steel structure column and the concrete foundation during installation can easily cause the auxiliary positioning device to shift, thus losing its positioning function. Summary of the Invention

[0005] Based on this, this application provides a cup-shaped foundation steel structure column installation positioning device to solve the problem that the steel structure column has a large self-weight, and when using detachable auxiliary positioning devices such as snap-fit ​​devices, the contact between the steel structure column and the concrete foundation during installation can easily cause the auxiliary positioning device to shift and lose its positioning function.

[0006] The technical solution to the above-mentioned technical problems in this application is as follows:

[0007] A cup-shaped foundation steel structure column installation and positioning device, set at the elevation of the steel structure column, includes:

[0008] A fixing plate and a positioning plate are provided. The fixing plate is welded to the steel structure column. The positioning plate is set perpendicular to the fixing plate and is provided with a scale.

[0009] Preferably, the end of the fixing plate away from the positioning plate is provided with an arc-shaped groove.

[0010] Preferably, the diameter of the arc-shaped groove is the same as the outer diameter of the steel structure column, and the chord length of the arc-shaped groove is not greater than one-quarter of the perimeter of the cross-section of the steel structure column.

[0011] Preferably, the system further includes a propulsion component, which includes a first jack, a second jack, and an auxiliary plate. The first jack is connected to the fixed plate, and the second jack is connected to the positioning plate. The auxiliary plate is detachably connected to the cup-shaped base, and the first jack and the second jack are detachably connected to the end of the auxiliary plate away from the cup-shaped base.

[0012] Preferably, the propulsion component further includes a housing, which covers the fixing plate and the positioning plate, and is detachably connected to the first jack and the second jack.

[0013] Preferably, a support plate is provided on the side of the auxiliary plate away from the positioning plate, and the support plate is used to support the auxiliary plate.

[0014] Preferably, a thickened plate is provided at one end of the fixing plate near the positioning plate, and the thickened plate is connected to the first jack.

[0015] Preferably, a reinforcing plate is provided at the end of the positioning plate away from the fixing plate, and the reinforcing plate is connected to the second jack.

[0016] Preferably, the lower end face of the positioning plate is provided with a groove, and a scale is slidably disposed in the groove.

[0017] The technical solution adopted in this application can achieve the following beneficial effects:

[0018] 1. By increasing the firmness of the fixing plate through welding, the problem of the steel structure column having a large self-weight is solved. When using detachable auxiliary positioning devices such as snap-fit ​​devices, the contact between the steel structure column and the concrete foundation during installation can easily cause the auxiliary positioning device to shift and lose its positioning function.

The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] Please see Figures 1 to 4 This application provides a cup-shaped foundation steel structure column installation and positioning device, which is set at the elevation of the steel structure column and includes: a fixing plate 100 and a positioning plate 200. The fixing plate 100 is welded to the steel structure column; the positioning plate 200 is set perpendicular to the fixing plate 100 and is provided with a scale.

[0029] Specifically, the fixing plate 100 is made of, but not limited to, I-beams, steel plates, steel blocks, etc., and different shapes of materials are used to make it according to the needs of the site. The positioning plate 200 is also made of, but not limited to, I-beams, steel plates, steel blocks, etc. Preferably, the fixing plate 100 and the positioning plate 200 are made of the same material. The fixing plate 100 and the positioning plate 200 are connected by welding or as a whole. The bottom of the positioning plate 200 is provided with scales, which can be set on the positioning plate 200 by engraving, patching, etc.

[0030] Further, the construction workers measured the elevation and marked it on the steel structure column. After marking, they aligned the lower end of the fixing plate 100 with the marked elevation (four plates were set up, symmetrically and equidistantly on the perimeter of the elevation). They then used an electric welding machine to weld the fixing plate 100 to the steel structure column, ensuring a firm weld on all contact surfaces. Simultaneously, they ensured that the positioning plate 200 was perpendicular to the fixing plate 100, and that the fixing plate 100 was parallel to the central axis of the steel structure column (the central axis of the steel structure column is the center line perpendicular to the horizontal plane when the column is erected). At the same time, the construction workers laid out lines on the upper surface of the cup-shaped foundation (the distance from the central axis of the steel structure column to the lines was the same, and the spacing was set according to the actual situation). The steel structure column is lifted by a crane and slowly placed into the reserved position in the cup-shaped foundation. When the positioning plate 200 contacts the upper surface of the cup-shaped foundation, the crane stops lowering the steel structure column. Then, the construction personnel observe the values ​​on the scale of the positioning plate 200 and compare the four values. They then adjust the position of the steel structure column by manually pushing or mechanically moving it until the four values ​​are the same. After that, the subsequent construction can proceed. This completes the installation and positioning of the steel structure column. (If the fixing plate 100 has been used before, the construction personnel need to measure the width of the fixing plate 100, adjust the scale, or increase the thickness of the fixing plate 100 to make the scale on the four positioning plates 200 reach the same position on the outer surface of the steel structure column.)

[0031] The technical solution of the cup-shaped foundation steel structure column installation and positioning device adopted in this application can achieve the following beneficial effects:

[0032] 1. By increasing the firmness of the fixing plate 100 through welding, the problem of the steel structure column having a large self-weight is solved. When using detachable auxiliary positioning devices such as snap-fit ​​devices, the contact between the steel structure column and the concrete foundation during installation can easily cause the auxiliary positioning device to shift and lose its positioning function.

[0033] 2. By setting scales on the positioning plate 200, the problem of not being able to clearly see the distance parameters and direction to be moved when moving steel structure columns is solved.

[0034] Based on the above solution, an arc-shaped groove 120 is provided at the end of the fixing plate 100 away from the positioning plate 200. The diameter of the arc-shaped groove 120 is the same as the outer diameter of the steel structure column, and the chord length of the arc-shaped groove 120 is no greater than one-quarter of the perimeter of the steel structure column cross-section. By providing the arc-shaped groove 120, the contact area between the fixing plate 100 and the steel structure column is increased, thereby increasing the stability of the fixing plate 100 and the positioning plate 200. By limiting the chord length of the arc-shaped groove 120, the width of the fixing plate 100 is limited. A shorter chord length reduces damage to the steel structure column during welding or cutting, and solves the problems of wasted force due to a large welding area and high ultimate bearing capacity of the fixing plate 100, as well as long cutting time and low efficiency due to a large welding area.

[0035] In a preferred embodiment of this application, a propulsion component 300 is further included, which includes a first jack 310, a second jack 320, and an auxiliary plate 330. The first jack 310 is connected to the fixed plate 100, and the second jack 320 is connected to the positioning plate 200. The auxiliary plate 330 is detachably connected to the cup-shaped base, and the first jack 310 and the second jack 320 are detachably connected to the end of the auxiliary plate 330 away from the cup-shaped base.

[0036] The fixed ends of the first jack 310 and the second jack 320 are detachably connected to the auxiliary plate 330 by means of snap-fit, bolt connection, etc. The auxiliary plate 330 is made of, but is not limited to, steel plates, I-beams, etc., and is not limited to plate types. The first jack 310 is located above the second jack 320 (the auxiliary plate 330 is set vertically, with the top facing away from the ground). The first jack 310 is connected to the end of the fixed plate 100 away from the positioning plate 200, and the second jack 320 is connected to the end of the positioning plate 200 away from the fixed plate 100. When the positioning plate 200 contacts the upper surface of the cup-shaped foundation and the crane stops on the lower steel structural column, the construction workers install the auxiliary plate 330 on the side wall of the cup-shaped foundation, opposite to the positioning plate 200 (the horizontal projections coincide), and install the first jack 310 and the second jack 320 on the auxiliary plate 330. By observing the values ​​corresponding to the scale and lines, the workers control the extension and retraction of the first jack 310 and the second jack 320, so that under the control of the construction workers, they can move the steel structural column to the designated position, and then stop the extension and retraction of the first jack 310 and the second jack 320. By setting up the first jack 310, the second jack 320 and the auxiliary plate 330, the problem of the inability to control the distance of manual pushing or hoisting, which makes it difficult to move the steel structural column to the preset position, is solved.

[0037] Furthermore, to protect the first jack 310 and the second jack 320, the propulsion component 300 also includes a housing 350. The housing 350 covers the fixed plate 100 and the positioning plate 200, and is detachably connected to the first jack 310 and the second jack 320. Both the fixed plate 100 and the positioning plate 200 are provided with grooves 352, extending vertically, and located on the side of the fixed plate 100 near the positioning plate 200 and the side of the positioning plate 200 away from the fixed plate 100, respectively. The housing 350 is n-shaped, with bosses at both ends. The bosses slide and limit the grooves 352, and cover the fixed plate 100 and the positioning plate 200. The first jack 310 and the second jack 320 are connected to the housing 350 by bolts, chucks, etc. By sliding the bosses from top to bottom to the bottom of the grooves 352, the second jack 320 is positioned corresponding to the positioning plate 200. At the end furthest from the fixed plate 100, the first jack 310 is positioned at one end of the fixed plate 100. After the housing 350 is installed, the auxiliary plate 330 is fixed to the side wall of the cup-shaped foundation. The first jack 310 and the second jack 320 are adjusted so that their fixed ends are in contact with the auxiliary plate 330. Then, the steel structure column is moved as needed. By setting up the housing 350, the first jack 310 and the second jack 320 are protected. At the same time, the housing 350 is connected to the first jack 310 and the second jack 320, reducing the installation time of the first jack 310 and the second jack 320 and improving work efficiency.

[0038] In the preferred design, to increase the ultimate compressive strength of the auxiliary plate 330, a support plate 340 is provided on the side of the auxiliary plate 330 away from the positioning plate 200. The support plate 340 is used to support the auxiliary plate 330. The support is located on the side of the auxiliary plate 330 away from the positioning plate 200, and at the end of the auxiliary plate 330 away from the cup-shaped foundation. The other end of the support can be connected to the ground, foundation, etc. When the first jack 310 and the second jack 320 push the steel structure column, the auxiliary plate 330 is used as the fulcrum. By adding the support plate 340, the auxiliary plate 330 is made more stable, solving the problem that the auxiliary plate 330 may shift or be damaged when the first jack 310 and the second jack 320 push the steel structure column, causing the steel structure column to be unable to move; at the same time, the safety of the auxiliary plate 330 is improved.

[0039] In another preferred embodiment of this application, a thickened plate 110 is provided at the end of the fixing plate 100 near the positioning plate 200, and the thickened plate 110 is connected to the first jack 310. A reinforcing plate 210 is provided at the end of the positioning plate 200 away from the fixing plate 100, and the reinforcing plate 210 is connected to the second jack 320. Both the thickened plate 110 and the reinforcing plate 210 are provided with U-shaped slots 211 that open upwards (away from the ground). The size of the U-shaped slots 211 is the same as the size of the telescopic ends of the first jack 310 and the second jack 320. The thickened plate 110 and the reinforcing plate 210 are fixedly connected to the fixed plate 100 and the positioning plate 200, respectively. By setting the thickened plate 110 and the reinforcing plate 210, the ultimate compressive strength of the fixed plate 100 and the positioning plate 200 is increased, solving the problem that the fixed plate 100 and the positioning plate 200 are easily squeezed and deformed. At the same time, by setting the U-shaped slots 211 on the thickened plate 110 and the reinforcing plate 210, the first jack 310 and the second jack 320 are positioned, solving the problem that the fixed plate 100 or the positioning plate 200 may be damaged due to incorrect installation position caused by operational errors during installation.

[0040] Based on the above solution, a groove 220 is provided on the lower end face of the positioning plate 200, and a scale 230 is slidably disposed within the groove 220. Scale markings created by spraying, engraving, or other methods are prone to falling off or wearing down. The scale 230 is slidably engaged within the groove 220. When the scale 230 is worn and unusable, it can be slid out of the groove 220 and replaced with a new scale 230. This method is simple and convenient, solving the problems of difficult maintenance and scale markings becoming illegible to the human eye due to external factors.

[0041] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
