Abstract
Description
Technical Field
[0001] This application relates to the technical field of large square footing construction, and particularly relates to a large square footing structure. Background Art
[0002] Large square footing structures are mostly seen in strip foundations under masonry walls. To meet the requirements of foundation bearing capacity, they are the enlarged parts of the walls or columns of buildings underground. Their function is to bear the loads transmitted from the upper structure of the building and transfer them together with their own weights to the foundation.
[0003] When conducting large square footing construction on the shore, riverbank, or seaside, tide waiting construction is required. First, the foundation is excavated at low tide. After filling the pond slag to the designed high tide level, the foundation is compacted, and then brick stacking begins. Among them, when at the seaside, the water will rise. If brick stacking is used for large square footing construction, the overall construction progress, that is, the construction efficiency, may be affected by the water, which needs further improvement. Utility Model Content
[0004] In order to improve the construction efficiency of the large square footing structure, this application provides a large square footing structure.
[0005] A large square footing structure provided by this application adopts the following technical solutions:
[0006] A large square footing structure includes a box body with a hollow interior, a steel bar frame placed inside the box body, and concrete filled in the box body. The box body is made of metal material. A plurality of through holes are spaced along the length direction on the upper surface of the box body. Cross bars are provided on the opposite side walls of the box body, and lifting lugs are provided on the cross bars. A plurality of lifting lugs are spaced along the length direction of the cross bars.
[0007] By adopting the above technical solutions, by setting the box body, the height of the upper surface of the box body can be higher than the average high tide level to provide a certain isolation effect against the external water, thereby improving the construction efficiency of the large square footing structure and facilitating the solidification of the internal concrete. With the steel bar frame placed inside the box body and the concrete poured through the through holes, it replaces the large square footing structure made of brick stacking in the prior art, with a relatively fast construction speed, that is, further improving the construction efficiency of the large square footing structure. And the overall bearing capacity is also relatively high. During installation, usually, the steel bar frame is first installed inside the box body on the ground and then hoisted to the excavated foundation by a crane. Due to the added steel bars, the weight of the overall box body increases significantly. If the rope is directly wound around the box body, there may be a possibility of damage during hoisting. Therefore, by setting the cross bars and lifting lugs on the cross bars, the acting forces borne during hoisting are relatively uniform, reducing the possibility of damage to the box body.
[0008] Preferably, the box body includes a frame body with an open upper end surface and a cover plate welded to the opening of the frame body, and the through hole is arranged on the cover plate.
[0009] By adopting the above technical solution, the box body is split into a frame body and a cover plate welded to the opening of the frame body, so as to install the steel bar frame in the frame body, facilitating the installation of the steel bar frame and reducing the installation difficulty of the steel bar frame.
[0010] Preferably, the frame body includes a container cut in half along the horizontal direction and a steel plate welded to the opening on the side of the container.
[0011] By adopting the above technical solution, for the frame body, the container is cut in half along the horizontal direction to form two frame bodies, enabling the reuse of discarded empty containers, reducing the use of other materials, and for the large square footing structure by the sea, it is convenient for collection, transportation to the construction site for processing. Among them, since one side of the container is open, it is sealed with a steel plate.
[0012] Preferably, angle steels are fixedly connected between the frame body and the cover plate, and the angle steels are respectively fixedly connected to the upper surface of the cover plate and the side wall of the frame body.
[0013] By adopting the above technical solution, by setting the angle steels, the sealing effect between the cover plate and the frame body can be further improved, that is, the sealing effect on the inside of the container is improved, reducing the possibility of water entering the box body after subsequent water swelling.
[0014] Preferably, screw rods are fixedly penetrated through the opposite side walls of the frame body, several screw rods are arranged at intervals along the length direction of the frame body, the screw rods penetrate through the cross bar, and nuts are threadedly connected to the screw rods.
[0015] By adopting the above technical solution, by setting the screw rods, the connection strength between the cross bar and the box body can be improved, and it is also convenient to disassemble the cross bar for reuse, reducing costs.
[0016] Preferably, both ends of the screw rod respectively penetrate through the cross bars located on both sides of the frame body.
[0017] By adopting the above technical solution, both ends of the screw rod respectively penetrate through the cross bars located on both sides of the frame body, so as to play a pulling effect when the nuts are threadedly connected, improving the bearing capacity of the frame body during subsequent lifting and reducing damage to the frame body.
[0018] Preferably, the lifting lug is provided with a connecting component, and the lifting lug is detachably connected to the cross bar through the connecting component.
[0019] By adopting the above technical solution, since the cross bar is detachable for repeated use, the lifting lug is detachably connected to the cross bar through the connecting component so as to replace the damaged lifting lug.
[0020] Preferably, the connecting component includes a connecting plate fixedly connected to the lifting lug and a bolt passing through the connecting rod. The cross bar is provided with threaded holes for threaded connection of the bolts, and a plurality of the threaded holes are arranged at intervals along the length direction of the cross bar.
[0021] By adopting the above technical solution, the lifting lug is mounted on the cross bar through the connecting plate and the bolt. The mounting strength of the bolt is relatively high and it is also convenient for replacement.
[0022] Preferably, a sliding groove is formed on the upper surface of the cross bar. The length direction of the sliding groove is parallel to the length direction of the cross bar. The sliding groove extends to the opposite end faces of the cross bar. The connecting plate is slidably connected to the sliding groove. The connecting plate protrudes with a limiting block, and a limiting groove for the limiting block to slide is formed on the inner wall of the sliding groove. The threaded hole is arranged on the inner wall of the sliding groove.
[0023] By adopting the above technical solution, by providing the sliding groove, the connection strength between the lifting lug and the cross bar can be further improved. And by arranging the threaded hole in the sliding groove, the possibility that the bolt slides off under the influence of external force when it is exposed to the outside can be reduced.
[0024] In summary, the utility model has the following beneficial effects:
[0025] 1. By providing the box body, the height of the upper surface of the box body can be higher than the average high tide level to achieve a certain isolation effect on the external water, thereby accelerating the construction efficiency of the large square footing structure and facilitating the solidification of the internal concrete.
