Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to a cargo station ground slit structure and a cargo station thereof. Background Art

[0002] In logistics buildings or other large-space operation buildings, it is common to use concrete floors (floors) on a large scale. The large-scale pouring of concrete in pieces faces the defects of the material itself. Since concrete is a brittle material, it faces cracking caused by thermal expansion and contraction after large-scale paving. Although there are steel bars in the surface layer, they will be damaged and cracked in the face of the huge tensile force generated by thermal expansion and contraction. Moreover, these cracks develop in irregular, disordered and unpredictable directions, thus affecting the aesthetics and daily use. In cargo stations, the ground is heavily loaded, and forklifts or trailers will drive on it for a long time. Under repeated rolling, cracks will accelerate the damage of the ground. At the same time, the damage of the ground will affect the driving of vehicles inside, and the cycle will repeat. Utility Model Content

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but the embodiments should not be construed as limiting the present invention.

[0023] See also Figure 1 The utility model of the cargo terminal ground slit structure comprises a structural floor 1, wherein the structural floor 1 is provided with a plurality of parallel structural floor slits 6 in the longitudinal and transverse directions, a plurality of induced cracks 2 are provided between two adjacent structural floor slits 6, the induced cracks 2 are partially disconnected, and the induced cracks 2 are also perpendicular to each other in the longitudinal and transverse directions, a plurality of induced cracks 2 are provided between two adjacent structural floor slits 6, and the structural floor 1 is provided with a structural deformation joint (not shown in the figure) as an anti-crack joint.

[0024] See also Figures 2 to 3 The structural floor 1 around the square columns 4 arranged in the freight terminal is provided with a prismatic through-slit 5 surrounding the square columns 4, each of the structural floor through-slits 6 corresponds to a row of square columns 4, and both ends of each structural floor through-slit 6 are respectively connected to the prismatic through-slit 5, and asphalt mortar 9 is provided in the prismatic through-slit 5. The top of the structural floor 1 within the range of the prismatic through-slit 5 is provided with a C15 filling layer 12 and a floor paint layer 13, and the C15 filling layer 12 and the floor paint layer 13 are arranged in sequence from bottom to top.

[0025] See also Figure 1 There are two to three induced cracks 2 evenly distributed on the structural floor 1 within a span of a column, and the spacing between the induced cracks 2 is not greater than 6m.

[0026] See also Figure 4 The induced crack 2 is plugged with a PE rod 7 and the crack surface is provided with a polyurethane caulking layer 8.

[0027] See also Figure 5 The seam of the structural floor slab through-seam 6 is stuffed with asphalt mastic 9, and the seam surface is provided with an asphalt mastic caulking layer 10, and the two sides of the structural floor slab through-seam 6 are respectively provided with mutually separated force transmission steel bars 11.

[0028] The seam edges of the structural deformation seams are provided with hemming angle steels or armor seams.

[0029] See also Figure 3 and Figure 6The structural floor 1 next to the wall is provided with a straight through seam 3 parallel to the direction of the wall, the gap between the square column 4 corner 14 and the structural floor 1 is provided with asphalt mastic 9, and the gap between the square column 4 corner 14 and the C15 filling layer 12 and the floor paint layer 13 is provided with an asphalt mastic filling layer 10.

[0030] In one or more embodiments, the distance between the two structural floor seams 6 is not greater than 30m, and the width of the structural floor seam 6 is 10-15mm; the induced cracks 2 are 5mm wide and 35mm deep; the widths of the prismatic seams 5 and the straight seams 3 are both 10mm; and the thickness of the floor paint layer 13 is 1mm.

[0031] Before the implementation of the utility model, it is first necessary to clarify whether the structural floor 1 is provided with a temperature expansion joint (not shown in the figure). If there is a temperature expansion joint, a through joint, i.e., the aforementioned structural deformation joint, needs to be provided at the location of the structural expansion joint. The seam width is recommended to be the same as the structural expansion joint, and angle steel edging or armor seam can be provided at the seam edge as required. If the structural floor 1 is a whole, this does not need to consider the corresponding relationship with the structural floor 1 split seam. The utility model is not limited to whether there is a structural deformation joint and whether angle steel edging and armor seam are provided.

[0032] According to the column grid size, a structural floor seam 6 is set within 30m, and the width of the structural floor seam 6 is 10-15mm. Of course, 30m is only a reference size, and the specific data is subject to the column grid.

[0033] Within a column span, two or three induced cracks 2 can be divided in a column span according to the size of the column span. The spacing between the induced cracks 2 should not be greater than 6m. The width of the induced crack 2 is 5mm, and the depth is 1 / 3 of the plate thickness. In one or more embodiments, the depth is 35mm. The above dimensions are used as a reference dimension. Slightly enlarged or reduced are all within the protection scope of the utility model.

[0034] A prism-shaped through seam 5 is arranged around the square column 4, and the width of the prism-shaped through seam 5 is 10 mm. Within the prism range, a fireproof floor paint or epoxy floor paint is used as the floor paint layer 13, and the thickness is 1 mm. Of course, the material of the floor paint layer 13 is not limited to fireproof floor paint and epoxy floor paint, and any material that meets the specification requirements and has a certain elasticity can be used.

[0035] Along the direction of the wall, a straight line through seam 3 with a width of 10 mm is cut. The wall is not limited to an interior wall or an exterior wall, and the masonry material of the wall is not limited.

[0036] The induced crack 2 is filled with PE rods, and the seam surface is filled with polyurethane. At the same time, the surface filling material polyurethane should be selected with a deformation coefficient of more than 25% to meet the daily temperature deformation expansion and contraction. Therefore, the filling material is required to have a certain elasticity and wear resistance. Other materials with the same or similar properties can also be selected. In addition, when filling the seams, it is necessary to pay attention to the temperature during the operation, the middle value of the highest temperature and the lowest temperature under normal conditions in the local area, such as about 20 degrees in the southern region. The stable value is not limited to a specific value, and it can be around the middle temperature.

[0037] The utility model discloses a cargo terminal, which comprises a structural floor slab 1 and square columns 4. The structural floor slab 1 has the above-mentioned cargo terminal ground slit structure.

[0038] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
