Description

Technical Field

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] Precast concrete utility tunnels are a new technology developed and applied for the first time in China. They offer superior structural stability and lower maintenance costs compared to traditional steel-structured utility tunnels. Precast utility tunnels consist of two parts: precast columns and precast beams.

[0004] The precast columns of prefabricated concrete pipe galleries are constructed by pre-embedded column bases, internally reserved reinforcing bars, and concrete pouring. The heaviest precast column currently weighs 16.2 tons, thus placing higher demands on the prefabrication accuracy of the pre-embedded column bases. The precast column bases of prefabricated pipe galleries must match corresponding molds, and the positional accuracy of the precast column base plates must be within ±1mm, with a large number of precast column bases required. Traditional assembly methods using marking lines for column bases have disadvantages such as slow assembly speed and low accuracy. To meet construction requirements, the column bases need to be assembled quickly while meeting the accuracy requirements. Utility Model Content

[0020] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0021] The present invention will be described in detail below with reference to the accompanying drawings. This embodiment discloses a column base assembly fixture applied to a column-and-column-separated structure, such as... Figure 1 As shown, it includes a limiting plate base 3, and a limiting plate assembly 1 is provided on the upper part of the limiting plate base 3; like Figure 3 As shown, the limiting plate assembly 1 includes a first limiting plate 101, which is disposed at one end of the upper part of the limiting plate base 3, and a second limiting plate 102 is disposed at the other end of the upper part of the limiting plate base 3; a first limiting elongated plate 103 is disposed at one end of the second limiting plate 102, and a first limiting frame 104 is disposed between the first limiting plate 101 and the second limiting plate 102; the first limiting frame 104 is disposed at the front and rear ends of the limiting plate base 3, a second limiting frame 106 is disposed at one end of the front end of the first limiting frame 104, a third limiting vertical plate 110 is disposed at the other end, and a second limiting vertical plate 109 is disposed at one end of the third limiting vertical plate 110; limiting blocks 107 are disposed at both ends of the rear end of the first limiting frame 104, a first limiting vertical plate 108 is disposed on the side of the limiting block 107, and a second limiting elongated plate 105 is disposed at the rear of the limiting block 107.

[0022] The various limiting plates on the limiting plate group 1 are divided into the first limiting group 11 to the sixth limiting group 16. All the limiting plates are spot welded to the limiting plate base 3 according to the size of the precast column foot. The limiting plates are combined to form a limiting group. The limiting group, together with the wedge, fixes the position of the precast column foot plate. After the plate is fixed, the plate of the precast column foot is spot welded to fix it.

[0023] like Figure 4As shown, the components of the limiting plate group 1, including the limiting plate, the limiting elongated plate, and the limiting frame, are divided into first to fourth limiting groups 14. The first limiting group 11 includes a second limiting plate 102, a second limiting frame 106, and a limiting block 107. During installation, a first side plate 7 is placed between the second limiting plate 102 and the second limiting frame 106. One end of the first side plate 7 is in close contact with the second limiting plate 102, and the other end is in close contact with the second limiting frame 106. The side of the first side plate 7 is in close contact with the limiting block 107, thus achieving limiting of the first side plate 7 in three directions, thereby completing the precise installation of the first side plate 7.

[0024] The second limiting assembly 12 includes a first limiting plate 101, another limiting block 107, a first limiting vertical plate 108, and a second limiting vertical plate 109. During installation, another first side plate 7 is placed on the side of the first limiting plate 101, with one end of the first side plate 7 in close contact with the first limiting plate 101, and the other end of the first side plate 7 in close contact with the first limiting vertical plate 108 and the second limiting vertical plate 109. The side of the first side plate 7 is in close contact with the other limiting block 107, achieving limiting in three directions, thus completing the precise installation of the other first side plate 7.

[0025] The third limiting group 13 includes a first limiting frame 104 and a third limiting vertical plate 110. During installation, a second side plate 8 is placed between the first limiting frame 104 and the third limiting vertical plate 110. One end of the second side plate 8 is in close contact with the first limiting frame 104, and the other end is in close contact with the third limiting vertical plate 110. The first limiting frame 104 and the third limiting vertical plate 110 cooperate to achieve limiting in two directions. Since the first side plate 7 has been installed, the side of the second side plate 8 is in close contact with one end of the first side plate 7, thus achieving limiting in three directions and completing the precise installation of the second side plate 8.

[0026] The fourth limiting group 14 includes a second limiting frame 106 and another first limiting frame 104. When installing another second side plate 8, the second side plate 8 is placed between the first limiting frame 104 and the second limiting frame 106. One end of the second side plate 8 is tightly attached to the first limiting frame 104, and the other end is tightly attached to the second limiting frame 106. The first limiting frame 104 and the second limiting frame 106 cooperate to achieve limiting in two directions. The side of the second side plate 8 is limited by the already installed first side plate 7, and is tightly attached to one end of the first side plate 7, thus achieving limiting in three directions and completing the precise installation of the other second side plate 8.

[0027] like Figure 5As shown, the fifth limiting group 15 includes a first limiting plate 103 and a second limiting plate 105. The first limiting plate 103 and the second limiting plate 105 cooperate to realize the installation of the column base plate. This is done after the first side plate 7 and the second side plate 8 are installed. The lower surface of the column base plate is in close contact with the upper surface of the first side plate 7 and the second side plate 8. One side of the column base plate is in close contact with the first limiting plate 103, and the other side is in close contact with the second limiting plate 105. This allows the column base plate to be limited in both the horizontal and vertical directions, thus achieving precise installation of the column base plate.

[0028] The sixth limiting group 16 includes a first limiting plate 101 and a second limiting plate 102. Multiple first limiting plates 101 are arranged horizontally, with equal spacing between them. Each first limiting plate 101 is fixedly connected to a limiting plate base 3. Multiple second limiting plates 102 are also arranged horizontally, with through holes between them. Each second limiting plate 102 is fixedly connected to the limiting plate base 3.

[0029] Three first limiting plates 101 are provided, distributed at the upper, middle, and lower parts of one end of the limiting plate base 3. The upper and lower first limiting plates 101 are used to limit the first stiffening plate 9. By tightly abutting the side of the first stiffening plate 9 against the side of the first limiting plate 101, the installation of the first stiffening plate 9 on one side can be completed. Three second limiting plates 102 are provided. By tightly abutting the side of the first stiffening plate 9 against the side of the first stiffening plate 9, the first stiffening plate 9 on the other side can be limited. The first limiting plates 101 and the second limiting plates 102 can limit the first side plate 7 and the first stiffening plate 9, ensuring accurate installation position.

[0030] The first limiting plate 103 is horizontally positioned, with its middle sidewall fixedly connected to the second limiting plate 102, and its lower sidewall fixedly connected to the limiting plate base 3. The second limiting plate 105 is vertically positioned, with its middle sidewall fixedly connected to the limiting block 107, and its lower sidewall fixedly connected to the limiting plate base 3. The first and second limiting plates 103 work together to limit the installation of the column base, ensuring accurate positioning.

[0031] The first limiting vertical plate 108 and the third limiting vertical plate 110 are vertically arranged, and the second limiting vertical plate 109 is horizontally arranged. The first limiting vertical plate 108, the second limiting vertical plate 109, and the third limiting vertical plate 110 are fixedly connected to the limiting plate base 3. The first limiting frame 104 is fixedly connected to the limiting plate base 3, and the second limiting frame 106 is fixedly connected to the limiting plate base 3.

[0032] The first limiting frame 104 is "n"-shaped, consisting of one horizontal plate and two vertical plates. The vertical plates limit the first side plate 7, and the horizontal and vertical plates work together to limit the second side plate. The second limiting frame 106 is "L"-shaped, consisting of two vertical plates, one vertically positioned and the other horizontally positioned. The vertically positioned plate limits the second side plate 8, and the horizontally positioned plate limits the first side plate 7.

[0033] like Figure 2 As shown, a rotating mechanism is provided at the lower end of the limiting plate base 3, and a fixed base 2 is provided at the lower end of the rotating mechanism. The rotating mechanism is fixedly connected to the limiting plate base 3 and the fixed base 2. The rotating mechanism includes a reducing shaft 6, the lower end of which is fixedly connected to the fixed base 2, and a bearing 4 is sleeved on the upper end of the reducing shaft 6. A sleeve 5 is provided on the bearing 4, the bearing 4 is located inside the sleeve 5, and the upper end of the sleeve 5 is fixedly connected to the limiting plate base 3.

[0034] The rotating mechanism includes a reducing shaft 6, a bearing 4, and a sleeve 5. The reducing shaft 6 is spot-welded to the fixed base 2. The small end of the reducing shaft 6 is fitted with the inner side of the bearing 4, and the outer side of the bearing 4 is fitted with the sleeve 5. The sleeve 5 is spot-welded to the limiting plate base 3. The rotating mechanism is used to rotate the entire tooling when assembling prefabricated column feet. Workers can adjust the appropriate angle to assemble the column feet, which is convenient to operate and improves work efficiency.

[0035] like Figure 6 As shown, the column base consists of a column base plate, two first side plates 7, two second side plates 8, four first stiffening plates 9, and four second stiffening plates 10. The column base assembly fixture allows for precise and rapid assembly of the column base plate, first side plates 7, second side plates 8, and first stiffening plates 9 at key locations. The second stiffening plates 10 are welded to the column base after the other column base plates are spot-welded to the fixture and removed from it. This later welding is to ensure the structural dimensions of the column base (the second stiffening plate has a larger heat input; welding it first could easily lead to component deformation).

[0036] Installation method: like Figure 7 As shown, the first side plate 7 is positioned and fixed by the first limiting group 11 in conjunction with the wedge; as Figure 8 As shown, the two second side plates 8 are fixed by the third limiting group 13 and the fourth limiting group 14 (in conjunction with the wedge and the first side plate 7); Figure 9 As shown, the second limiting assembly 12 (which works with a wedge and two second side plates 8) is used to fix another first side plate 7 with the wedge; after the two first side plates 7 and two second side plates 8 are assembled, the side plates are spot-welded together for fixation; as shown Figure 10As shown, the four first stiffening plates 9 are positioned using the sixth limiting group 16, the first side plate 7, and the second side plate 8, and then spot-welded to the first side plate 7 and the second side plate 8; Figure 11 As shown, the column base plate is positioned using the fifth limiting group 15 and then spot-welded to the first side plate 7, the second side plate 8, and the first stiffening plate 9. After assembly, the external wedges are removed, and the precast column foot (assembled) is lifted out.

[0037] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
