Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a rapid and accurate positioning device for steel column installation and its usage method. Background Technology

[0002] In steel structure design, cup-shaped column bases are often used when the bending moment at the column base is large. The embedment depth is 1.5 to 2.0 times the height of the steel column section. However, since there are no anchor bolts during construction, it is impossible to accurately position the steel column relative to the axis. Usually, construction workers in the industry temporarily fix the column by inserting wedge-shaped steel plates into the side of the cup-shaped wall during construction.

[0003] When installing the steel column, the wedge-shaped steel plate is tilted to form a cup shape. However, once the wedge-shaped steel plate is tilted to a certain angle, it will be fixed. But the tilt angle of the steel plate is fixed, which limits its application range. When the angle of the steel plate is inconsistent with the tilt angle of the inner wall of the cup, the steel plate needs to be continuously hammered to adjust the position of the steel column and center it. This makes the centering and positioning of the steel column during installation inconvenient. The hammering process is difficult to control in terms of force and precision, and the speed is slow. It is also very likely to damage the side wall of the cup. Summary of the Invention

[0004] To address the inconvenience and low efficiency of centering steel columns when installing them on a cup-shaped base, this invention provides a rapid and precise positioning device and method for steel column installation.

[0005] The steel column installation rapid and accurate positioning device and its usage method provided by this invention adopt the following technical solution:

[0006] In a first aspect, a rapid and precise positioning device for steel column installation includes a clamping assembly and a positioning assembly. The clamping assembly includes a plurality of clamping members distributed around the steel column to restrict the lateral degree of freedom of the steel column. The positioning assembly includes a plurality of positioning members corresponding one-to-one with the clamping members. Each of the clamping members is provided with an mounting member for mounting on the positioning member. The distance between the mounting member and the clamping member is adjustable. The positioning member is fixedly installed on the top of the cup opening.

[0007] Optionally, the clamping assembly further includes several adjusting members that correspond one-to-one with the clamping members. The adjusting members are fixed to the top of the clamping members and are used to adjust the distance between two opposing clamping members.

[0008] Optionally, the mounting component is sleeved on the positioning component in a vertical direction, and the bottom end of the mounting component is flared.

[0009] Optionally, the positioning component further includes a pulley rotatably disposed at the top of the positioning member, wherein the rotation direction of the pulley (22) is the same as the movement direction of the mounting member.

[0010] Optionally, the bottom end of the positioning member is provided with a fixing plate, the fixing plate is fixed to the top of the cup mouth, and one end of the flared end of the mounting member abuts against the fixing plate.

[0011] Optionally, a connector is provided on one side of the mounting component in the horizontal direction, and the connector is slidably disposed on the clamping component in the horizontal direction.

[0012] Secondly, a method for using a rapid and precise positioning device for steel column installation includes the following steps:

[0013] S1. Mark the horizontal and vertical axes of the steel column at the top of the cup opening and draw a vertical line. Grind the concrete within this area to ensure that the entire surface within this area is level.

[0014] S2. Measure the actual distance between two pairs of points on the cross line. Based on the dimensions of the steel column, the distance from the edge of the steel column to the cross point on the cup opening can be calculated.

[0015] S3. Align the cross lines set on the fixing plate of the positioning component with the cross lines marked on the cup mouth, and then fix the positioning component on the concrete cup mouth.

[0016] S4. Fix the four clamping parts around the steel column to be hoisted using the adjusting parts. Adjust the exposed length of the connecting parts according to the distance between the edge of the steel column and the cross point on the cup mouth.

[0017] S5. Lift the steel column and lower it down. Align the flared end of the installation component with the positioning component fixed on the cup opening, and then slowly lower it down. The installation component will automatically fit onto the positioning component.

[0018] In summary, the present invention has at least one of the following beneficial effects: during installation, the steel column can be positioned more accurately within the cup opening, and the installation is more convenient and the work efficiency is higher. Attached Figure Description

[0023] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0024] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0025] This invention discloses a rapid and precise positioning device for steel column installation and its usage method. (Refer to...) Figure 1 The rapid and precise positioning device for steel column installation includes a clamping assembly 1 and a positioning assembly 2. The clamping assembly 1 includes several clamping members 11. In this embodiment, the steel column has a rectangular cross-section, and four clamping members 11 are provided, with each clamping member 11 located on one of the four sides of the steel column. The clamping members 11 are made of square steel. The positioning assembly 2 includes four positioning members 21. In this embodiment, the positioning member 21 is a round steel bar. A fixing plate 23 is provided at the bottom of the positioning member 21. The fixing plate 23 is fixed to the top wall of the cup opening by bolts, so that the four positioning members 21 are fixed vertically on the four top walls of the cup opening.

[0026] A connector 13 is slidably installed horizontally on the side of the clamping member 11 away from the steel column. In this embodiment, the connector 13 is a square steel. An installation member 3 is welded and fixed vertically to the end of the connector 13 away from the clamping member 11. In this embodiment, the installation member 3 is a round steel and is sleeved on the positioning member 21. When installing the steel column, the four clamping members 11 are fixed to the side wall of the steel column. The position of the positioning member 21 is determined according to the size of the steel column and the size of the cup opening, and the positioning member 21 is fixed with bolts. The connector 13 is slid to adjust the distance between the installation member 3 and the clamping member 11. The steel column is inserted into the cup opening. The four installation members 3 are sleeved on the four positioning members 21, which facilitates the positioning of the steel column and also fixes the steel column in the cup opening, facilitating construction.

[0027] Reference Figure 1 and Figure 2 In order to facilitate the mounting part 3 to be fitted onto the positioning part 21, the bottom end of the mounting part 3 is flared, so that the bottom opening of the mounting part 3 is much larger than that of the positioning part 21, making it easier to fit the mounting part 3 onto the positioning part 21 and making the operation more convenient.

[0028] To facilitate a smoother installation of the mounting component 3 onto the positioning component 21, the positioning assembly 2 also includes a pulley 22 rotatably mounted on the top of the positioning component 21. The circumference of the pulley 22 abuts against the inner wall of the mounting component 3. When the mounting component 3 is placed onto the positioning component 21, the pulley 22 first abuts against the flared wall of the mounting component 3. The pulley 22 is compressed and rotates, simultaneously adjusting the position of the mounting component 3 so that it is completely fitted onto the positioning component 21. This reduces the friction between the inner wall of the flared opening of the mounting component 3 and the positioning component 21, making it easier to install the mounting component 3 onto the positioning component 21. Additionally, the top of the positioning component 21 is tapered.

[0029] To facilitate the adjustment of the position of the mounting part 3, a scale is provided on the top side of the connector 13. When moving the connector 13, the distance between the mounting part 3 and the clamping part 11 can be easily adjusted by observing the scale on the connector 13, making the adjustment more convenient.

[0030] Reference Figure 1 The clamping assembly 1 also includes four adjusting members 12. In this embodiment, the adjusting members 12 are steel plates. Each clamping member 11 corresponds to one adjusting member 12. The adjusting members 12 are welded and fixed to the clamping member 11. The four adjusting members 12 are arranged in a grid shape. The side walls of the clamping member 11 and the adjusting members 12 abut against the side wall of the column. Fixing members 14 are installed on two adjacent adjusting members 12. In this embodiment, the fixing members 14 are bolts. The fixing members 14 can fix two adjacent adjusting members 12 together and make the adjusting members 12 clamp the column, and make the clamping member 11 clamp the steel column.

[0031] To accommodate columns of different sizes, the clamping assembly 1 has movable slots 15 along its length in each adjusting member 12. When four adjusting members 12 are joined together, the movable slots 15 on adjacent adjusting members 12 can connect. The fixing member 14 is passed through the movable slots 15 on the two joined adjusting members 12, and nuts are threaded onto the upper and lower ends of the fixing member 14. The nuts are rotated to tighten them against the adjusting members 12, thus fixing the two adjusting members 12 together. When using columns of different sizes, the fixing member 14 is loosened, and the adjusting members 12 are moved to adjust the distance between the two opposing adjusting members 12. This allows columns of different sizes to pass through the space between the four adjusting members 12, making the clamping assembly 1 more versatile.

[0032] A method for using a rapid and precise positioning device for steel column installation includes the following steps:

[0033] Step 1: Mark the horizontal and vertical axes of the steel column at the top of the cup opening and draw a vertical line. Grind the concrete within this area to ensure that the entire surface within this area is level.

[0034] Step 2: Measure the actual distance between the two pairs of points on the cross line. Based on the dimensions of the steel column, the distance from the edge of the steel column to the cross point on the cup rim can be calculated.

[0035] Step 3: Align the cross lines on the fixing plate 23 of the positioning component 21 with the cross lines marked on the cup mouth, and then fix the positioning component 21 to the concrete cup mouth.

[0036] Step 4: Fix the four clamping parts 11 around the steel column to be hoisted using the adjusting parts 12. Adjust the exposed length of the connecting parts 13 according to the distance between the edge of the steel column and the cross intersection point on the cup mouth.

[0037] Step 5: Lift the steel column and lower it down. Align the flared end of the mounting piece 3 with the positioning piece 21 fixed on the cup opening, and then slowly lower it down. The mounting piece 3 will automatically fit onto the positioning piece 21, which can quickly achieve the positioning of the steel column.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
