Description

Technical Field

[0001] The invention belongs to the technical field of steel structure construction, and particularly relates to a box-type column quick installation device and an installation method. Background Art

[0002] Steel structure columns are prefabricated columns for building construction, referred to as steel columns. During the construction process, the steel columns need to be placed in the cup-mouth foundation first, and then aligned and fixed. In common construction methods, the alignment and fixation of steel columns are generally carried out using wedge blocks and cable wind ropes. The wedge blocks are placed between the inner wall of the cup-mouth foundation and the steel columns, and then the steel structure columns are moved to the center of the cup-mouth foundation by hammering the wedge blocks to achieve the purpose of alignment. After alignment, they are fixed with cable wind ropes, and then the wedge blocks are removed. The disadvantage of the above construction process is that it consumes manpower, especially the use of cable wind ropes, which requires multiple people to assist in the work. The wedge blocks are not convenient to remove after being pressed, and the wedge blocks are also easy to damage the cup-mouth foundation during the hammering process, causing errors. Summary of the invention

[0003] The purpose of the present invention is to provide a box-type column quick installation device and installation method in order to solve the above problems.

[0004] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0005] A box-type column quick installation device, comprising a positioning structure for positioning a steel column at the center of a cup base, and a fastening structure for pre-fixing the steel column, the positioning structure comprising four long plates, a lower edge box arranged below one side of the long plate, a telescopic wedge-shaped base arranged inside the lower edge box, and a wedge-shaped positioning block arranged on the inclined surface of the wedge-shaped base, a steel plate is arranged between the wedge-shaped positioning block and the steel column, and a buckle rod that is mutually buckled with the wedge-shaped positioning block is arranged at the top of the steel plate;

[0006] The fastening structure includes a cross bar arranged below the two ends of the long board and parallel to the long board, the lower surface of the cross bar is provided with an arc-shaped groove, an internal threaded tube is clamped inside the arc-shaped groove, the internal thread of the internal threaded tube is connected to an external threaded rod, the end of the internal threaded tube is provided with a supporting base plate for contacting the base surface of the cup mouth, the outer surface of the middle section of the internal threaded tube is slidably sleeved with a ring, the end of the external threaded rod is provided with a supporting limit foot for contacting the steel plate, the outer surface of the ring is provided with a spoke rod, and the bottom end of the long board is provided with a driving member corresponding to the spoke rod.

[0007] As a further optimization scheme of the present invention, the cross section of the wedge-shaped positioning block is I-shaped. Setting the cross section to be I-shaped can increase the contact area of ​​the side surface of the wedge-shaped block and avoid excessive local pressure when subjected to force.

[0008] As a further optimization scheme of the present invention, telescopic rods are provided at both ends of the four long boards, and pins are provided at the intersection of adjacent telescopic rods. Since there is no support at the bottom of the lower edge box, in order to prevent the long boards and the lower edge box from falling due to unstable center of gravity, the four long boards are fixed to each other to form a rectangle or square, which is more stable when used.

[0009] As a further optimization scheme of the present invention, a double-headed screw extending above the long board is provided inside the lower edge box, and two threaded sliders are provided on the surface of the double-headed screw. A hinged connecting rod is provided between the threaded slider and the wedge-shaped base, and a limit piece for limiting the stroke is provided at the right-angle end of the wedge-shaped base. The above method of driving the wedge-shaped base to extend and retract has strong force bearing capacity and does not require locking. The threaded slider is driven to move by the thread. When the wedge-shaped base is extended to the maximum stroke, the hinged connecting rod is perpendicular to the double-headed screw, serving as a force support point for the wedge-shaped base.

[0010] As a further optimization solution of the present invention, the driving member includes a rotating rod rotatably arranged inside the long board, and a driving disc with spokes is arranged at the bottom end of the rotating rod, so as to facilitate the fastening structure to operate quickly from above the long board.

[0011] As a further optimization scheme of the present invention, each of the internal threaded tube is fixed by two cross bars, and the two cross bars are located on both sides of the ring. The two cross bars are suspended under the long board through the lower edge block. By setting up two cross bars, the internal threaded tube can be better clamped without affecting the rotation of the internal threaded tube. The cross bars located on both sides of the ring help to distribute the force evenly and prevent the internal threaded tube from falling out of the arc-shaped groove under the force.

[0012] As a further optimization scheme of the present invention, the bottom end of the steel column is provided with pre-positioning steel bars, and the side surface of the bottom end of the steel column is provided with root nails for increasing the connection strength with concrete. The support limit feet are arranged corresponding to the root nails. The root nails are a conventional operation, which imitates the plant root system to increase the adhesion of the steel column after casting. The root nails can be used to limit the external threaded rod, and there is no need to additionally limit the external threaded rod when operating the fastening structure.

[0013] As a further optimization scheme of the present invention, the collar is composed of two half rings spliced ​​together, the splicing direction is parallel to the axis of the collar, the internal threaded tube and the external threaded rod are cast in concrete together with the steel column, and the spliced ​​collar can be easily recycled and reused, but the collar will be subjected to torque during operation, so its splicing direction needs to avoid the direction of the torque.

[0014] In order to implement the above-mentioned installation device, the present invention also proposes a method for installing a box-type column using a box-type column quick installation device, comprising the following steps:

[0015] S1: hoist the steel column into the cup mouth foundation, insert the internal threaded tube into the arc-shaped slot, place the long board to the center of the top edge of the cup mouth foundation, and make the lower edge box stick to the inner wall of the cup mouth foundation;

[0016] S2: Extend the wedge-shaped base outward to the maximum and fix it. Buckle the steel plate with the surface of the wedge-shaped positioning block and place it between the wedge-shaped base and the steel column. Draw a mark on the surface of the steel column and hammer the wedge-shaped base to make the two opposite wedge-shaped bases maintain the same height.

[0017] S3: Use a wrench to fix the external threaded rod to prevent it from rotating, drive the ring to rotate through the spoke rod, drive the internal threaded tube to rotate through the ring, the external threaded rod is rotated out of the internal threaded tube, the support base plate at the end of the internal threaded tube is pressed against the inner wall of the cup base, and the support limit foot at the end of the external threaded rod presses the steel plate against the surface of the steel column;

[0018] S4: Release the wedge-shaped base to retract it, take out the wedge-shaped positioning block, take out the long plate and its connected components, disengage the internal threaded tube from the arc-shaped slot, and pour concrete into the cup mouth foundation.

[0019] The beneficial effects of the present invention are:

[0020] The present invention provides an integrated positioning structure and a fastening structure, which makes it faster and more convenient to position and fix the steel column. The telescopic wedge-shaped base can be used to quickly disassemble and assemble the wedge-shaped positioning block, and only wedge-shaped positioning blocks of different specifications are needed to adapt to steel columns of various sizes. The steel column can also be pre-fixed directly by the fastening structure, which saves manpower and simplifies the operation compared to cable wind rope fixation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0030] Example 1

[0031] like Figure 1-6 As shown, a box-type column quick installation device includes a positioning structure 3 for positioning a steel column 2 at the center of a cup base 1, and a fastening structure 4 for pre-fixing the steel column 2. The positioning structure 3 includes four long plates 31, a lower edge box 32 arranged below one side of the long plate 31, a telescopic wedge-shaped base 36 arranged inside the lower edge box 32, and a wedge-shaped positioning block 311 arranged on the inclined surface of the wedge-shaped base 36. A steel plate 312 is arranged between the wedge-shaped positioning block 311 and the steel column 2, and a buckle rod 313 that is mutually buckled with the wedge-shaped positioning block 311 is arranged at the top of the steel plate 312;

[0032] The fastening structure 4 includes a cross bar 44 arranged below the two ends of the long board 31 and parallel to the long board 31, an arc-shaped groove 45 is opened on the lower surface of the cross bar 44, an internal threaded tube 46 is clamped inside the arc-shaped groove 45, the internal thread of the internal threaded tube 46 is connected with an external threaded rod 47, the end of the internal threaded tube 46 is provided with a supporting base plate 411 for contacting the surface of the cup mouth base 1, a ring 48 is slidably sleeved on the outer surface of the middle section of the internal threaded tube 46, and a supporting limit foot 410 for contacting the steel plate 312 is provided at the end of the external threaded rod 47, a spoke rod 49 is provided on the outer surface of the ring 48, and a driving member corresponding to the spoke rod 49 is provided at the bottom end of the long board 31, and the driving member includes a rotating rod 41 rotatably arranged inside the long board 31, and a driving disc 42 with spokes is provided at the bottom end of the rotating rod 41. It should be noted that the ring 48 is slidably arranged with the internal threaded tube 46, and the contact surface is provided with stripes for driving the internal threaded tube 46 to rotate.

[0033] The cross section of the wedge-shaped positioning block 311 is an I-shape. Setting the cross section to be an I-shape can increase the contact area of ​​the side surface of the wedge-shaped block 311 and avoid excessive local pressure when subjected to force.

[0034] Telescopic rods 39 are provided at both ends of the four long boards 31, and pins 310 are provided at the intersection of adjacent telescopic rods 39. Since there is no support at the bottom of the lower edge box 32, in order to prevent the long boards 31 and the lower edge box 32 from falling due to unstable center of gravity, the four long boards 31 are fixed to each other to form a rectangle or square, which is more stable when used.

[0035] A double-headed screw 33 extending above the long plate 31 is provided inside the lower edge box 32, and two threaded sliders 34 are provided on the surface of the double-headed screw 33. A hinged connecting rod 35 is provided between the threaded slider 34 and the wedge-shaped base 36. A limit piece 37 for limiting the stroke is provided at the right-angle end of the wedge-shaped base 36. The above-mentioned method of driving the wedge-shaped base 36 to extend and retract has strong force bearing capacity and does not require locking. The threaded slider 34 is driven to move by the thread. When the wedge-shaped base 36 is extended to the maximum stroke, the hinged connecting rod 35 is perpendicular to the double-headed screw 33, serving as a force support point for the wedge-shaped base 36.

[0036] Each internal threaded tube 46 is fixed by two cross bars 44, and the two cross bars 44 are located on both sides of the collar 48. The two cross bars 44 are suspended below the long plate 31 through the lower edge block 43. By providing two cross bars 44, the internal threaded tube 46 can be better clamped without affecting the rotation of the internal threaded tube 46. The cross bars 44 are located on both sides of the collar 48, which helps to evenly distribute the force and prevent the internal threaded tube 46 from falling out of the arc-shaped groove 45 under the force.

[0037] In order to implement the above-mentioned installation device, the present invention also proposes an installation method using the above-mentioned box-type column quick installation device, comprising the following steps:

[0038] S1: hoist the steel column 2 into the cup mouth foundation 1, insert the internal threaded tube 46 into the arc-shaped slot 45, place the long board 31 to the center of the top edge of the cup mouth foundation 1, and make the lower edge box 32 stick to the inner wall of the cup mouth foundation 1;

[0039] S2: Extend the wedge-shaped base 36 outward to the maximum and fix it, buckle the steel plate 312 with the surface of the wedge-shaped positioning block 311, and place it between the wedge-shaped base 36 and the steel column 2, draw a mark on the surface of the steel column 2, and hammer the wedge-shaped base 36 to keep the heights of the two opposite wedge-shaped bases 36 consistent;

[0040] S3: Use a wrench to fix the external threaded rod 47 to prevent it from rotating, drive the ring 48 to rotate through the spoke rod 49, drive the internal threaded tube 46 to rotate through the ring 48, the external threaded rod 47 rotates out of the internal threaded tube 46, the support base plate 411 at the end of the internal threaded tube 46 is pressed against the inner wall of the cup base 1, and the support limit foot 410 at the end of the external threaded rod 47 presses the steel plate 312 against the surface of the steel column 2;

[0041] S4: Release the wedge-shaped base 36 to retract it, take out the wedge-shaped positioning block 311, take out the long plate 31 and its connected components, disengage the internal threaded tube 46 from the arc-shaped slot 45, and pour concrete into the cup mouth foundation 1.

[0042] Example 2

[0043] Different from Example 1, the bottom end of the steel column 2 is provided with pre-positioning steel bars to facilitate the initial positioning of the steel column 2. The side surface of the bottom end of the steel column 2 is provided with root nails 21 for increasing the connection strength with concrete. The support limit foot 410 is arranged corresponding to the root nail 21. The root nail 21 is a conventional setting, which imitates the plant root system to increase the adhesion of the steel column 2 after pouring. In this embodiment, the root nail 21 is used to limit the external threaded rod 47. In the above step S3, the "using a wrench to fix the external threaded rod 47 to prevent it from rotating" is omitted, and there is no need to additionally restrict the rotation of the external threaded rod 47 when operating the fastening structure.

[0044] Example 3

[0045] Different from the first embodiment, the collar 48 of the present embodiment is composed of two half-rings. Figure 7 As shown, the splicing direction is parallel to the axial direction of the collar, and the internal threaded tube 46 and the external threaded rod 47 are cast in the concrete together with the steel column 1. The spliced ​​collar 48 can be easily recycled and reused, but the collar 48 will be subjected to torque during operation, so its splicing direction needs to avoid the direction of the torque.

[0046] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
