Description
The technical field is as follows:
the invention relates to a pre-embedded anti-cutting steel foundation in a reinforced concrete slab.
Background art:
in the construction process of industrial and electric engineering, large-scale equipment is usually required to be installed on reinforced concrete floors and composite floors, equipment foundation bases are usually required to be elevated so as to facilitate pipe network laying, dynamic load is generated in the operation process of the equipment, and therefore embedded parts need to meet corresponding anchoring depth according to standard requirements. In the structural design, factors such as positioning of embedded parts, anchoring, punching resistance of a floor slab, an equipment raising method and the like are usually considered, and in order to prevent punching damage of the floor slab and cracking damage caused by insufficient anchoring depth, the thickness of the floor slab is properly considered in the design, so that the increase of engineering cost is brought along; meanwhile, along with the popularization of the fabricated building in industry and electric power engineering, the application of the profiled steel sheet floor slab is more and more extensive, the uneven structure of the profiled steel sheet limits the positioning and anchoring depth of the embedded parts, and brings great challenges to the design of related embedded parts, so that the prior art is necessarily improved to overcome the defects in the prior art.
The invention content is as follows:
the invention provides a pre-embedded anti-cutting steel foundation in a reinforced concrete slab to solve the problems in the prior art.
The technical scheme adopted by the invention is as follows:
the utility model provides a pre-buried type is anti dashes and is cut steel basis among reinforced concrete slab, includes support column, anti dashes and cuts the board, buries a layer and has the profiled sheet of frontal and valley face, and a plurality of support column is separated by a determining clearance and sets up side by side and form the supporter, two on the frontal of profiled sheet was arranged in to the supporter parallel to each other, at the waist welding anti dashes and cuts the board of every support column, profiled steel and anti dashes and cut the board and all pre-buried in burying a layer, the top of support column stretches outside burying a layer.
Further, the support column is of an H-shaped steel beam structure.
Furthermore, the bottom surface of support column has the welding to have the backup pad, and the support column is arranged in on the frontal surface of profiled sheet through the backup pad.
Furthermore, the anti-cutting plate is of a rectangular plate structure, an H-shaped hole is formed in the anti-cutting plate, and the anti-cutting plate is horizontally welded on the support column.
Further, the embedded part layer is formed by pouring concrete.
The invention has the following beneficial effects:
the embedded part layer can be adjusted according to the height of the embedded part layer, and the engineering adaptability is strong; set up anti die-cut board on the support column of H type, can effectively prevent the die-cut destruction of structure, the backup pad size of bottom can set up according to the profiled sheet model, and nimble easy operation can effectively reduce the time limit for a project, and economy practices thrift, safe and reliable.
Description of the drawings:
FIG. 1 is a structural view of a support pillar, an impact-cut plate and a profiled steel sheet according to the present invention.
Fig. 2 is a diagram illustrating an application of the present invention.
The specific implementation mode is as follows:
the invention will be further described with reference to the accompanying drawings.
Referring to fig. 1 and 2, the pre-buried impact-cutting-resistant steel foundation for reinforced concrete slabs according to the present invention includes supporting columns 12, impact-cutting-resistant plates 13, a buried layer 10, and a profiled steel sheet 2 having a front surface and a valley surface, wherein a plurality of supporting columns 12 are arranged side by side with a certain gap therebetween to form supporting bodies, two supporting bodies are arranged in parallel on the front surface of the profiled steel sheet 2, the impact-cutting-resistant plates 13 are welded to the waist of each supporting column 12, and the buried layer 10 is formed by casting concrete. The profiled steel sheet 2 and the anti-cutting plate 13 are both embedded in the embedded part layer 10, the top end of the support column 12 extends out of the embedded part layer 10, and the top end of the support column 12 is fixedly provided with an installation beam 11 for overhead equipment. The height of the supporting columns 12 can be adjusted according to the height of the embedded layer 10.
The supporting column 12 is in an H-shaped steel beam structure, so that the supporting column 12 is better supported on the profiled steel sheet 2, a supporting plate 14 is welded on the bottom surface of the supporting column 12, and the supporting column 12 is placed on the front surface of the profiled steel sheet 2 through the supporting plate 14.
The anti-cutting plate 13 is of a rectangular plate structure, an H-shaped hole is formed in the anti-cutting plate 13, and the anti-cutting plate 13 is horizontally welded on the support column 12.
The invention is suitable for profiled steel plate concrete combined floor boards, the supporting columns 12 are fixed above the wave crests of the profiled steel plates, the supporting plates 14 on the bottom surfaces of the supporting columns 12 can be set to be reasonable in length according to the types of the profiled steel plates, so that the supporting plates 14 are kept stable above the wave crests of the profiled steel plates, and the width of the supporting plates 14 is not less than 2 times of the wave width of the profiled steel plates.
The anti-punching area can be increased by the anti-punching plate 13, the bearing capacity of a steel foundation is improved, and the anti-punching plate is suitable for installation and fixation of large-scale equipment on a composite floor slab and a concrete floor slab.
