Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a segmented hoisting and fixing device for ultra-high precast columns. Background Technology

[0002] Ultra-high precast columns are core components of prefabricated buildings. They refer to concrete columns with unconventional heights that are prefabricated in factories and then transported to the site for installation. They are produced using standardized methods and integrate components such as steel bars and embedded parts, resulting in high construction efficiency.

[0003] Patent CN223358450U discloses a segmented hoisting and fixing device for ultra-high precast columns. It utilizes positioning components to initially position and connect fixed angle steel to the lower precast column. After two adjacent fixed angle steels are fixed to the adjacent vertical edges of the lower precast column using tie rods, the two fixed angle steels form positioning surfaces in three directions, providing positioning reference and hoisting limits for the upper precast column. After the upper and lower precast columns are spliced, two more fixed angle steels are used to surround two more adjacent vertical edges, forming a stable structural system around the precast column. Grouting is then performed to complete the precast column splicing. However, this segmented hoisting and fixing device for ultra-high precast columns requires four fixed angle steels, necessitating multiple positioning operations on each of the four sides, causing inconvenience for construction workers. Summary of the Invention

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a segmented hoisting and fixing device for ultra-high precast columns.

[0005] A segmented hoisting and fixing device for ultra-high precast columns includes a first fixing angle steel and a second fixing angle steel that surround the splice joint between the upper and lower precast columns; The first fixed angle steel and the second fixed angle steel are both right-angle bent shapes, and the free ends of the first fixed angle steel and the second fixed angle steel are connected by positioning angle steel after they intersect. The first fixed angle steel cloth is provided with a first strip hole, the second fixed angle steel cloth is provided with a second strip hole, and the positioning angle steel cloth is provided with a third strip hole that matches the first and second strip holes. The first fixed angle steel and the positioning angle steel are connected by a positioning component passing through the matching first and third strip holes, second and third strip holes.

[0006] Furthermore, the first fixing angle steel includes two first fixing plates that are integrally arranged and perpendicular to each other; The first fixing plate has a first latch with an outward opening, and a first strip hole is provided above and below the first latch; The first fixing plate is also provided with a first auxiliary positioning hole, and the two right-angle bends of the first fixing plates are provided with a second auxiliary positioning hole.

[0007] Furthermore, the first auxiliary positioning hole and the second auxiliary positioning hole are flush with each other and are used to pass through the positioning bolts connecting the lower precast column.

[0008] Furthermore, the second fixing angle steel includes two integrally arranged and mutually perpendicular second fixing plates; The second fixing plate has a second latch with an outward opening, and a second strip hole is provided above and below the second latch; A third auxiliary positioning hole is provided at the right-angle bend of the two second fixing plates.

[0009] Furthermore, the second fixing plate is also provided with a fourth auxiliary positioning hole that is flush with the third auxiliary positioning hole. The third and fourth auxiliary positioning holes are used to pass through the positioning bolts of the lower precast column.

[0010] Furthermore, the first fixing plate extends into the second bayonet, and the second fixing plate extends into the first bayonet.

[0011] Furthermore, the positioning angle steel includes two integrally arranged and mutually perpendicular third fixing plates; The third fixing plate has several third strip-shaped holes.

[0012] Furthermore, the first strip hole, the second strip hole, and the third strip hole are all horizontal holes; The first auxiliary positioning hole, the second auxiliary positioning hole, the third auxiliary positioning hole, and the fourth auxiliary positioning hole are all horizontal holes.

[0013] Furthermore, the height of each of the third strip holes is adapted to the height of the first strip hole and the second strip hole, respectively.

[0014] Furthermore, a rubber pad layer is also provided on the inner side of the first fixing plate and the second fixing plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This segmented hoisting and fixing device for ultra-high precast columns first aligns the openings of the first and second fixing angle steels and then fits them onto the outside of the lower precast column. The right angles of the first and second fixing angle steels are then engaged with the diagonal points of the lower precast column. The first fixing plate extends into the second locking slot, and the second fixing plate extends into the first locking slot, forming an interlocking state. Then, a positioning angle steel is placed on the outside of the intersection of the first and second fixing angle steels. Bolts are used to pass through the overlapping third and first strip holes, as well as the overlapping third and second strip holes, to achieve a fixed connection between the positioning angle steel and the first and second fixing angle steels.

[0016] This ultra-high precast column segmented hoisting and fixing device only requires two fixing angle steels to interlock with each other, and at the same time, auxiliary positioning angle steels can fix the joint of the upper and lower precast columns. In operation, only the two opposite corners of the precast column need to be fixed. The two fixing angle steels are interlocked and easy to install and remove, and there will be no interference or jamming during the interlocking process.

[0017] Furthermore, the connecting holes are designed as strip holes, which are more flexible in adjustment and can be adapted to the fixing of precast column splicing joints of different lengths and widths. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5 As shown, this embodiment provides a segmented hoisting and fixing device for ultra-high precast columns, including a first fixing angle steel and a second fixing angle steel that surround the joint between the upper precast column 1 and the lower precast column 2. The first and second fixing angle steels are both right-angled bends, and their free ends intersect and are connected by a positioning angle steel. The first fixing angle steel has a first strip-shaped hole, the second fixing angle steel has a second strip-shaped hole, and the positioning angle steel has a third strip-shaped hole that matches the first and second strip-shaped holes. A positioning element passes through the matching first and third strip-shaped holes, and the second and third strip-shaped holes, to connect the first fixing angle steel and the positioning angle steel, as well as the second fixing angle steel and the positioning angle steel. The positioning element can be a bolt, or other parts that can be inserted and fixed.

[0026] Specifically, such as Figures 2-4 As shown, the first fixing angle steel includes two integrally arranged and mutually perpendicular first fixing plates 3. Each first fixing plate 3 has an outward-facing first latch 31, with first strip-shaped holes 32 above and below the latch 31. The first fixing plate 3 also has a first auxiliary positioning hole 33, and a second auxiliary positioning hole 34 is formed at the right-angle bend of the two first fixing plates 3. In this embodiment, the first auxiliary positioning hole 33 communicates with the first latch 31, and the first auxiliary positioning hole 33 and the second auxiliary positioning hole 34 are flush, used to pass through and connect the positioning bolt 4 of the lower precast column 2. A connecting thread 21 is pre-embedded in the lower precast column 2, and the positioning bolt is adapted to the connecting thread 21.

[0027] Specifically, such as Figure 2 , Figure 3 and Figure 5As shown, the second fixing angle steel includes two integrally arranged and mutually perpendicular second fixing plates 5. Each second fixing plate 5 has an outward-facing second latch 51, with second strip-shaped holes 52 above and below the latch 51. A third auxiliary positioning hole 53 is provided at the right-angle bend of the two second fixing plates 5. The second fixing plate 5 also has a fourth auxiliary positioning hole 54 flush with the third auxiliary positioning hole 53. Both the third and fourth auxiliary positioning holes 53 and 54 are used to pass through and connect the positioning bolts 4 of the lower precast column 2. The fourth auxiliary positioning hole 54 is longer than the second strip-shaped hole 52, facilitating flexible installation of the positioning bolts 4. The fourth auxiliary positioning hole 54 can also be used for connection with the positioning angle steel.

[0028] In this embodiment, the first fixing plate 3 is inserted into the second bayonet 51, and the second fixing plate 5 is inserted into the first bayonet 31. By using positioning angle steel for connection, the fixing device at the joint of the upper and lower precast columns can be installed, and grouting and other operations can then be carried out.

[0029] In this embodiment, the positioning angle steel includes two integrally arranged and mutually perpendicular third fixing plates 6. The third fixing plate 6 has a third strip-shaped hole 61.

[0030] Specifically, the first strip hole 32 of the first fixing angle steel, the second strip hole 52 of the second fixing angle steel, and the third strip hole 61 of the positioning angle steel are all horizontal holes; and multiple holes are provided for each.

[0031] The first auxiliary positioning hole 33, the second auxiliary positioning hole 34 of the first fixed angle steel, and the third auxiliary positioning hole 53 and the fourth auxiliary positioning hole 54 of the second fixed angle steel are all horizontal holes.

[0032] Furthermore, the height of the third slot 61 of the positioning angle steel is adapted to the height of the first slot 32 of the first fixed angle steel and the second slot 52 of the second fixed angle steel. Bolts pass through the corresponding third slot 61 and first slot 32, and through the corresponding third slot 61 and second slot 52, thus achieving a fixed connection between the positioning angle steel and the first and second fixed angle steels. Due to the structural design of the first latch 31 of the first fixed angle steel and the second latch 51 of the second fixed angle steel, the first and second fixed angle steels can be adaptively connected according to the length and width of the precast column. Furthermore, since the first slot 32 of the first fixed angle steel, the second slot 52 of the second fixed angle steel, and the third slot 61 of the positioning angle steel are all horizontal slots, they can accommodate the fixing of the first and second fixed angle steels at different positions, making adjustment convenient and operation simple.

[0033] In this embodiment, a rubber pad layer is also provided on the inner side of the first fixing plate 3 and the second fixing plate 5.

[0034] The segmented hoisting and fixing device for ultra-high precast columns provided in this embodiment is used by first aligning the openings of the first and second fixing angle steels and then fitting them onto the outside of the lower precast column 2, so that the right angles of the first and second fixing angle steels are respectively engaged with the diagonal points of the lower precast column 2, and the first and second fixing angle steels are close to the outer side wall of the lower precast column 2; the upper precast column 1 slowly falls along the guide surface formed by the two fixing angle steels to achieve initial alignment of the joint; after the joint is in place, the first fixing plate 3 is inserted into the second locking slot 51, and the second fixing plate 5 is inserted into the first locking slot 31 to form an interlocking state. Then, a positioning angle steel is placed on the outside of the intersection of the first and second fixing angle steels, and bolts are used to pass through the overlapping third strip hole 61 and the first strip hole 32, as well as the overlapping third strip hole 61 and the second strip hole 52, to achieve a fixed connection between the positioning angle steel and the first and second fixing angle steels. After the installation of this fixing device is completed, grouting will begin. Once the concrete at the joint is poured and formed, the fixing device can be removed and reused in other locations.

[0035] The segmented hoisting and fixing device for ultra-high precast columns provided in this embodiment only requires two interlocking fixing angle steels and auxiliary positioning angle steels to fix the joint between the upper precast column 1 and the lower precast column 2. Operationally, fixing only needs to be performed at two opposite corners of the precast column, thus optimizing the structure and simplifying the operation. Furthermore, the interlocking and snap-fitting method of the two fixing angle steels facilitates installation and disassembly, and prevents interference or jamming during the interlocking process.

[0036] In this embodiment, the connecting holes are designed as strip holes, which are more flexible in adjustment and can be adapted to the fixing of precast column splicing joints of different lengths and widths.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
