Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and in particular relates to a matrix assembled steel pipe column system. Background Art

[0002] In recent years, with the advancement of bridge construction technology, steel pipe column supports have become widely used due to their structural stability and material savings. During construction, the steel pipe columns in the steel pipe column supports are often cut and welded to the required length based on on-site construction needs, which is cumbersome and affects construction efficiency.

[0003] Prefabricated steel pipe column supports are disclosed in the prior art. For example, CN208293437U discloses a prefabricated large-diameter steel pipe support structure for cast-in-place beams, comprising steel pipe columns, horizontal cross-links, and vertical diagonal cross-links. A connecting plate A is provided on the side surfaces of each end of the steel pipe column. The steel pipe columns, one or more, are arranged vertically side by side and then stacked and connected. The upper and lower portions of each steel pipe column are connected to an A connecting plate group via the A connecting plate group, which is then connected to the horizontal cross-links. A vertical diagonal cross-link is provided between the two parallel horizontal cross-links. One end of the vertical diagonal cross-link is connected to the A connecting plate on the upper side of the steel pipe column via the B connecting plate group, and the other end is connected to the A connecting plate on the lower side of the steel pipe column via the B connecting plate group.

[0040] The column bracket 1 is composed of a plurality of rectangular column units 2 fixedly connected in sequence up and down; the column unit 2 includes four column bodies 3 distributed in a rectangular shape and fixing members 4 arranged on the four sides of the column unit 2;

[0041] The fixing member 4 includes an upper cross-link 41 hinged at both ends to the top of the column body 3, a lower cross-link 42 hinged at both ends to the bottom of the column body 3, and a middle oblique link 43 hinged at the top to the top of the column body 3 and hinged at the bottom of another column body 3 at an angle downward. Specifically, hinge ears 31 corresponding to the fixing member 4 are welded to both ends of the column body 3. The upper cross-link 41 and the lower cross-link 42 are hinged at both ends of the hinge ears 31 close to the end of the column body 3. The middle oblique link 43 is hinged at both ends to the end of the hinge ears 31 away from the end of the column body 3. It should be noted that hinge holes 311 are spaced apart at upper and lower intervals on the hinge ears 31. Hinge plates 411 are welded at both ends of the upper cross-link 41, the lower cross-link 42, and the middle oblique link 43. Hinge connection can be achieved by passing a pin through the hinge plates 411 and the hinge holes 311 at the corresponding positions.

[0042] An inspection platform 5 is fixed to the outer periphery of the top of the column unit 2, and a guardrail 51 is fixed to the outside of the inspection platform 5; a triangular support frame 52 is fixed to the bottom of the inspection platform 5, and the triangular support frame 52 is welded to the outer wall of the column body 3;

[0043] The ladder 6 is arranged in the column unit 2, and the bottom of the ladder 6 is fixedly connected to the lower cross link 42, and the top is inclined upward and fixedly connected to the upper cross link 41; handrails 61 are fixed on both sides of the ladder 6; in this embodiment, a horizontal extension platform 62 is fixed to the top and bottom of the ladder 6 respectively; the extension platform 62 at the top of the ladder 6 is fixedly connected to the upper cross link 41; the extension platform 62 at the bottom of the ladder 6 is fixedly connected to the lower cross link 42; the extension platforms 62 at the top and bottom of the ladder 6 are respectively provided with makeshift grooves 621 corresponding to the upper cross link 41 and the lower cross link 42.

[0044] Flanges 32 are fixed to both ends of the column body 3 , and a plurality of bolt holes 321 are evenly opened on the flange 32 . Bolts are passed through the bolt holes 321 to fix and connect two upper and lower adjacent column bodies 3 .

[0045] In this embodiment, mutually perpendicular support rods 7 are provided on the top of the column unit 2, and both ends of the support rods 7 are fixedly connected to the upper cross link 41; a walking platform 8 is fixed on the top of the support rod 7, and a ladder opening 81 corresponding to the ladder 6 is left on the walking platform 8.

[0046] During use, the column unit 2 is first assembled. When assembling the column unit 2, the column body 3 is positioned according to the length of the upper cross-link 41 and the lower cross-link 42. Then, the lower cross-link 42 is hoisted to the hinge ears 31 at the bottom of two adjacent column bodies 3 on one side of the column unit 2 using an external machine. A pin is passed through the lower cross-link 42 and the corresponding hinge hole 311, and the two ends of the lower cross-link 42 are hinged to the hinge ears 31 near the end of the column body 3. Then, the middle oblique link 43 is hoisted to the same position using an external machine. A pin is passed through the middle oblique link 43 and the corresponding hinge hole 311, and the upper and lower ends of the middle oblique link 43 are hinged to the top and bottom of the column body 3 respectively. Finally, the upper cross-link 41 is hoisted and a pin is passed through the upper cross-link 41 and the corresponding hinge hole 311, and the two ends of the upper cross-link 41 are hinged to the hinge ears 31 near the end of the column body 3. Following the same method, the upper cross-joint 41, lower cross-joint 42, and middle diagonal joint 43 of the fixing member 4 are fixed around each column unit 2. During the assembly of the column units 2, the fixed ladder 6 is installed. After a column unit is assembled, the inspection platform 5 is installed on its top periphery. Meanwhile, the support rod 7 is welded to the upper cross-joint 41 at the top, and the walking platform 8 is laid on the support rod 7 and fixed to the support rod 7.

[0047] Then, the column unit 2 is hoisted to the appropriate position of the construction area with the help of external machinery, and then the column units 2 are hoisted and fixed in sequence. During the hoisting and fixing, the operator uses the ladder 6 to climb onto the maintenance platform 5, aligns the bolt holes 321 of the flanges 32 on the upper and lower column bodies 3, and then uses bolts through the bolt holes 321 to securely connect the two adjacent column bodies 3. Then, the upper and lower column units 2 are secured together, and so on, until the column bracket 1 is built to the appropriate height.

[0048] As can be seen from the above, the provision of the ladder 6, the inspection platform 5, and the walking platform 8 not only facilitates the erection of the column support 1 in this embodiment, but also facilitates the subsequent inspection and maintenance of the column support 1, meeting actual construction needs. It also provides excellent safety and stability. Furthermore, the upper cross-link 41, the lower cross-link 42, and the middle diagonal link 43 in the fixing member 4 are connected to the column body 3 using an articulated connection, making installation quick and convenient, helping to improve construction efficiency, and providing excellent stability. Furthermore, the provision of the extension platform 62 not only facilitates access to the inspection platform 5, but also facilitates the fixed connection of the ladder 6 to the upper cross-link 41 and the lower cross-link 42.
