Description

Technical Field

[0001] The present invention relates to the technical field related to building construction, and in particular to an auxiliary fixing frame for supporting raft steel bars. Background Art

[0002] A raft is a concrete slab used in foundation engineering, with the foundation beneath it and columns, walls, and other structures above it. The type of foundation used in a building is closely related to the type of subsoil and the distribution of soil layers. In engineering design, geological conditions often arise where the rock and soil beneath the basement slab is composed of weathered residual soil, fully weathered rock, strongly weathered rock, or moderately weathered soft rock, making it possible to use a natural foundation. High-rise building basements often serve as underground parking garages, which prohibit the use of excessive interior walls, thus limiting the use of box foundations. Raft foundations can fully utilize the foundation's bearing capacity, adjust for uneven settlement, and meet the space requirements of parking garages, making them an ideal foundation type. The main structural types of raft foundations are flat-plate raft foundations and beam-slab raft foundations. Flat-plate raft foundations are widely used in high-rise buildings due to their ease of construction.

[0003] Support fixation is one of the important factors to ensure the normal use of raft reinforcement. The traditional raft reinforcement construction method is relatively wasteful of materials, cannot meet the requirements of environmental protection and resource conservation, and is cumbersome to install, wastes human resources, and has low construction efficiency.

[0032] The section of the support column 3 located above the first support plate 1 is the raft steel bar connection section, and the section of the support column 3 located below the second support plate 2 is the anchoring section. An anchor is connected to the outer wall of the anchoring section, one end of the anchor is connected to the outer wall of the anchoring section, and the other end of the anchor is freely set.

[0033] Among them, multiple layers of steel bars can be set on the raft slab steel bar connection section, for example, two layers of steel bars can be set, namely the first steel bar layer 10 and the second steel bar layer 11, and the first steel bar layer 10 and the second steel bar layer 11 can be installed on the raft slab steel bar connection section; there are multiple support columns 3, and the provision of multiple support columns 3 can improve the support and fixation of the first support plate 1 and the second support plate 2 as well as the first steel bar layer 10 and the second steel bar layer 11, thereby improving the stability of the overall device. The first steel bar layer 10 and the second steel bar layer 11 have the same structure, and the height of the first steel bar layer 10 and the second steel bar layer 11 is 20 cm, so that the first steel bar layer 10 and the second steel bar layer 11 have high structural strength, thereby improving the reliability and safety of the overall device. The first steel bar layer 10 and the second steel bar layer 11 can both include transverse steel bars 12 and longitudinal steel bars 13, and the transverse steel bars 12 and the longitudinal steel bars 13 can be tied and fixed to the raft slab steel bar connection section of the support column 3 respectively.

[0034] like Figure 1 and Figure 2 As shown, in this embodiment, the first support plate 1 is provided with multiple rows of first through holes 14 extending vertically therethrough, and the second support plate 2 is provided with multiple rows of second through holes extending vertically therethrough. The first through holes 14 and the second through holes are arranged in a one-to-one correspondence, and each group of correspondingly arranged first through holes 14 and second through holes is penetrated by a support column 3.

[0035] The side of the first support plate 1 is provided with a plurality of horizontally arranged first bolt holes, the plurality of first bolt holes are arranged in parallel, and each first bolt hole is connected to a row of first through holes 14; the side of the second support plate 2 is provided with a plurality of horizontally arranged second bolt holes, the plurality of second bolt holes are arranged in parallel, and each second bolt hole is connected to a row of second through holes;

[0036] The support column 3 is provided with a third bolt hole and a fourth bolt hole arranged horizontally, the third bolt hole is connected to the corresponding first bolt hole, and the fourth bolt hole is connected to the corresponding second bolt hole;

[0037] A first bolt 9 is threadedly connected to each of the first bolt holes, and a second bolt 15 is threadedly connected to each of the second bolt holes. The first bolt 9 also passes through the third bolt hole on the corresponding row of support columns 3, and the second bolt 15 also passes through the fourth bolt hole on the corresponding row of support columns 3.

[0038] Preferably, the first bolt 9 is also threadedly connected to the corresponding third bolt hole, and the second bolt 15 is also threadedly connected to the corresponding fourth bolt hole. The first bolt 9 and the second bolt 15 can improve the stability of the support column 3, the first support plate 1, and the second support plate 2. By using the first bolt to mate with the first and third bolt holes, and the second bolt to mate with the second and fourth bolt holes, a stable connection between the first support plate and the support column and a stable connection between the second support plate and the support column can be achieved, resulting in a stable and reliable structure and convenient assembly and disassembly.

[0039] like Figure 1 and Figure 4 As shown, a specific embodiment of this embodiment comprises a fixed anchor head 7 and an anchor cable 6. An anchor seat 4 is provided on the anchoring section. One end of the anchor cable 6 is fixedly connected to the anchor seat 4, and the other end of the anchor cable 6 is fixedly connected to the fixed anchor head 7. The anchor cable 6 can be a prestressed anchor cable. Using a fixed anchor head and anchor cable allows the fixed anchor head to be buried within a stable rock mass and then grout-compacted, thereby increasing the supporting force of the anchor cable and, in turn, improving the stability of the support column.

The plurality of fixing columns 8 are equidistantly arranged below and in the middle of the support column 3. Winding the anchor rope 6 around several fixing columns 8 can increase the supporting force of the prestressed anchor rope 6, thereby improving the stable support of the support column 3.

[0042] like Figure 4 As shown, the fixed anchor head 7 of this embodiment has a conical structure, and one end of the anchor rope 6 is fixed at the center of the large end of the conical structure. The anchor rope is embedded in the stable rock mass through the anchor holder 4 and the fixing column 8, and then grouting and compacting is carried out to improve the supporting force of the anchor rope 6, thereby improving the stability of the support column 3.

[0043] Optionally, the anchor fixing seat 4 is a cylindrical structure or a hook-shaped structure.

[0044] like Figure 1 and Figure 2 As shown, the first support plate 1 and the second support plate 2 of this embodiment are both square plates and have the same shape and size.
