Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment, in particular to an angle separation device for square lattice column construction and a square lattice column supporting structure. Background Art

[0002] In large-scale foundation pit support projects, lattice columns are often used as efficient and economical temporary supports to connect the supporting structure and the surrounding soil. During structural construction, lattice columns often pass through the structural part to form temporary supports. A square lattice column, such as an easily disassembled assembled lattice column with application number 202222457525.0, comprises four vertically arranged angle steels, which are arranged in a square array. The four right angles of the four angle steels are the four corners of the square, and the adjacent angle steels are fixedly connected by tie plates. During construction, square lattice columns are used to pass through the concrete slab formwork system for temporary support. After the concrete slab construction is completed, the square lattice columns above and below the concrete slab need to be cut off. However, during dismantling, the cutting of the square lattice columns near the structural concrete will be subject to space restrictions, making cutting inconvenient. In addition, it is difficult to cut the square lattice columns to be flush with the upper and lower surfaces of the concrete slab, resulting in poor surface flatness of the concrete slab. Moreover, since the cut portions of the square lattice columns tend to protrude from the surface of the concrete slab, it is difficult to caulk the cut portions to prevent leakage, which affects the anti-seepage performance of the concrete slab.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0032] In this utility model, unless otherwise specified or limited, the terms "assemble," "connect," "connect," "fix," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0033] Example 1:

[0034] Figures 1 to 4An embodiment of the utility model is shown of an angle spacer device for square lattice column construction. The angle spacer device for square lattice column construction in this embodiment includes a first right-angle block 1 and a second right-angle block 2. One end of the first right-angle block 1 and the second right-angle block 2 are detachably connected by a bite assembly 3, and the other end is detachably connected by a snap assembly 4. A right-angle opening 5 is formed between the first right-angle block 1 and the second right-angle block 2 for the angle steel 61 of the square lattice column 6 to pass through.

[0035] When in use, the square lattice column 6 (the square lattice column 6 includes four vertically arranged angle steels 61, the four angle steels 61 are arranged in a square array, the four right angles of the four angle steels 61 are the four corners of the square, and the adjacent angle steels 61 are fixedly connected by a tie plate 62) is passed through the concrete slab 7, and the angle steels 61 of the square lattice column 6 and the corresponding upper and lower surfaces of the concrete slab 7 are respectively provided with square lattice column construction corner spacers, and the angle steels 61 of the square lattice column 6 are passed through the corresponding right-angle openings 5, and the top surfaces of the first right-angle block 1 and the second right-angle block 2 on the upper surface of the concrete slab 7 are flush with the upper surface, and the bottom surfaces of the first right-angle block 1 and the second right-angle block 2 on the lower surface of the concrete slab 7 are flush with the lower surface. After the concrete slab 7 has solidified, the concrete slab 7 and the first right-angle block 1 are separated and removed from the square lattice column 6. The first right-angle block 1 is then removed from the concrete slab 7. At this point, a gap is formed where the first and second right-angle blocks 1 and 2 were originally located, providing space for cutting the square lattice columns 6 at the upper and lower parts of the concrete slab 7. This avoids the inconvenience and unevenness of cutting the square lattice columns 6 due to space constraints. Furthermore, since the gap can be removed to form the gap, it is convenient to fill the gap with a sealing material 8, preventing water leakage at the cut and improving the anti-seepage performance of the concrete slab 7. On the other hand, it is convenient to fill the gap with the sealing material 8 and smooth it, improving the surface smoothness of the concrete slab 7.

[0036] Further, if Figure 3 and Figure 4 As shown, in this embodiment, the snap assembly 3 includes a snap bar 31 and a snap groove 32 that snap together. The snap bar 31 and the snap groove 32 are respectively provided on the first right-angle block 1 and the second right-angle block 2. The structure is simple and the processing is convenient.

[0037] Furthermore, in this embodiment, both the snapping strip 31 and the snapping groove 32 are parallel to the right-angled side. The snapping strip 31 is parallel to the right-angled side of the first right-angled block 1, and the snapping groove 32 is parallel to the right-angled side of the second right-angled block 2. In this way, the snapping strip 31 and the snapping groove 32 can snap together and separate along the length of the right-angled side.

[0038] Furthermore, in this embodiment, the bite strip 31 is fixed on the inner side of a right angle side of the first right angle block 1 and is parallel to the right angle side, and the bite groove 32 is provided on the inner side of a right angle side of the second right angle block 2 and is parallel to the right angle side.

[0039] like Figure 1 As shown, one end of the first right-angle block 1 and the second right-angle block 2 is an end of a right-angle side away from the right-angle portion b, and the other end of the first right-angle block 1 and the second right-angle block 2 is an end of another right-angle side away from the right-angle portion b (as shown in FIG. Figure 1 shown).

[0040] Furthermore, in this embodiment, the engagement groove 32 is an arcuate groove. That is, the cross-section of the engagement strip 31 is an arcuate surface, adapted to engage with the engagement groove 32. Thus, on the one hand, after the engagement groove 32 and the engagement strip 31 engage, the cooperation with the snap-fit assembly 4 prevents the first right-angle block 1 and the second right-angle block 2 from vertically displacing relative to each other. On the other hand, the engagement groove 32 and the engagement strip 31 cooperate to facilitate the combination of the first right-angle block 1 and the second right-angle block 2 by engaging and snapping, and to separate the first right-angle block 1 and the second right-angle block 2 by folding and then disengaging the engagement, thus facilitating the combination and separation of the first right-angle block 1 and the second right-angle block 2.

[0041] Furthermore, if Figure 3 As shown, in this embodiment, the snap-fit assembly 4 includes a lower snap plate 41 and an upper snap plate 42 respectively provided on the first right-angle block 1 and the second right-angle block 2. The upper snap plate 42 and the lower snap plate 41 are pressed against each other from top to bottom. The upper surface of the lower snap plate 41 is provided with a snap groove 411, and the lower surface of the upper snap plate 42 is provided with a snap block 421. The snap block 421 is snapped with the snap groove 411, and an elastic member 412 is pressed tightly between the snap groove 411 and the snap block 421. In this way, during the assembly process, the snap bars 31 and the snap groove 32 of the first right-angle block 1 and the second right-angle block 2 are first snapped together, and then the snap block 421 is snapped with the snap groove 411. The opposite is true when disassembling. The structure is simple and easy to assemble and disassemble. It is easy to install on the angle steel 61 of the square lattice column 6 and also easy to remove from the angle steel 61 of the square lattice column 6.

[0042] Furthermore, if Figure 3 As shown, in this embodiment, the lower buckle plate 41 is fixed to the first right-angle block 1, and the upper buckle plate 42 is fixed to the second right-angle block 2. The buckle groove 411 is provided along the length of the right-angle side. The buckle groove 411 is provided with a recessed groove 413 on the side away from the right-angle side. A buckle block 421 is provided with a protrusion 422 on one side. The protrusion 422 engages with the recessed groove 413. The elastic member 412 is provided on the first right-angle block 1 and abuts against the buckle block 421. Under the elastic force of the elastic member 412, the protrusion 422 engages with the recessed groove 413, providing a vertical separation and limiting function for the first and second right-angle blocks 1 and 2, preventing the first and second right-angle blocks 1 and 2 from vertically displacing relative to each other. When splitting, push the upper buckle plate 42 toward the elastic member 412 to separate the outer protrusion 422 from the inner recessed groove 413, and then the buckle block 421 and the buckling groove 411 can be separated up and down, thereby realizing the splitting of the first right-angle block 1 and the second right-angle block 2.

[0043] Specifically, the lower buckle plate 41 is fixed on the inner side of the other right-angle side of the first right-angle block 1 , and the upper buckle plate 42 is fixed on the inner side of the other right-angle side of the second right-angle block 2 .

[0044] Furthermore, in this embodiment, a handle 423 is provided on the upper buckle plate 42 to facilitate the buckle block 421 and the buckle groove 411 to engage and disengage operations.

[0045] Furthermore, in this embodiment, both ends of the first right-angle block 1 and the second right-angle block 2 are flush, and the upper and lower surfaces are flush.

[0046] Furthermore, in this embodiment, the elastic member 412 is an elastic block, such as a rubber block, a silicone block, etc. The elastic force of the elastic member 412, on the one hand, improves the engagement between the outer protrusion 422 and the inner recessed groove 413 to prevent accidental separation thereof, and on the other hand, facilitates the engagement and separation of the outer protrusion 422 and the inner recessed groove 413, thereby facilitating the assembly and disassembly of the first right-angle block 1 and the second right-angle block 2.

[0047] Example 2:

[0048] Figure 5 Another embodiment of the angle spacing device for square lattice column construction of the present invention is shown. The structure of this embodiment is basically the same as that of the first embodiment, and the difference lies in that the elastic member 412 includes a clamping block and a spring, and the spring is fixed between the clamping block and the inner side of the first right-angle block 1, and the clamping block is clamped to the side of the upper buckle plate 42 facing the first right-angle block 1.

[0049] Example 3:

[0050] Figures 6 to 8 An embodiment of the square lattice column support structure of the present invention is shown. The square lattice column support structure of this embodiment includes a square lattice column 6 and a concrete slab 7. The square lattice column 6 includes four vertically arranged angle steels 61. The four angle steels 61 are arranged in a square array. The four right angles of the four angle steels 61 are respectively the four corners of the square. Adjacent angle steels 61 are fixedly connected by a tie plate 62. The square lattice column 6 is passed through the concrete slab 7. The corresponding parts of the angle steels 61 and the upper and lower surfaces of the concrete slab 7 are respectively provided with the square lattice column construction angle spacer device of embodiment one or embodiment two. The angle steel 61 is passed through the corresponding right-angle opening 5. The top surface of the first right-angle block 1 and the second right-angle block 2 on the upper surface of the concrete slab 7 is flush with the upper surface, and the bottom surface of the first right-angle block 1 and the second right-angle block 2 on the lower surface of the concrete slab 7 is flush with the lower surface.

[0052] Figure 8The diagram is a schematic diagram of the main structure after the corner device is removed. A gap is formed after the concrete slab 7 removes the corner device, and the gap is filled with a plugging material 8 and smoothed to improve the surface smoothness of the concrete slab 7.
