Detailed Description
The present invention will be described in further detail with reference to specific examples, but the present invention is not limited thereto.
Referring to fig. 1 to 4, an embodiment of the present invention provides a concrete supporting structure for an open cut foundation pit, specifically including a concrete supporting rod 1 and supporting beams 2, wherein the concrete supporting rod 1 is disposed between the supporting beams 2; connecting seats 3 are prefabricated at two ends of the concrete supporting rod 1; two rows of threaded sleeves 4 are prefabricated at the positions, opposite to the connecting seats 3, of the inner sides of the supporting beams 2, two rows of bolt holes 3-1 corresponding to the threaded sleeves 4 are formed in the two sides of the connecting seats 3, high-strength bolts 5 penetrate through the bolt holes 3-1 to be fixedly connected with the threaded sleeves 4, and the concrete supporting rods 1 are fixedly connected with the supporting beams 2. When the concrete support bar needs to be disassembled, concrete does not need to be cut, and the concrete support bar 1 can be separated from the support beam 2 only by disassembling the high-strength bolt 5, so that the construction efficiency is improved.
Furthermore, a groove 6 is formed in the supporting beam 2 between the two columns of threaded sleeves 4, a boss 3-2 extends outwards from the center of the outer end of the connecting seat 3, the boss 3-2 is embedded into the groove 6, and when the high-strength bolt 5 connecting the concrete supporting rod 1 and the supporting beam 2 is in an accident and causes connection looseness, the high-strength bolt can be temporarily supported by the boss 3-2 and the groove 6, so that the reliability of the structure is improved.
In order to enable the concrete support rod 1 to smoothly enter the groove 6, the upper end of the groove is opened. When the concrete supporting rod 1 is hoisted to enter the groove 6, the concrete supporting rod 1 directly enters the groove 6 smoothly through the opening at the upper end of the groove.
Further, a beam support 7 is prefabricated below the groove 6 of the support beam 2, and the lower end of the concrete support rod 1 is seated above the beam support 7. On one hand, the beam support 7 can also improve the connection strength of the concrete support rod 1 and the support beam 2, so that the whole connection structure is safer and more reliable; on the other hand, the shearing strength of the bolt-connected concrete supporting rod 1 can be ensured.
The concrete support rod is characterized in that a rectangular pipe 8 extends outwards from the center of the inner end of the connecting seat 3, the rectangular pipe 8 is located between two rows of bolt holes 3-1, a plurality of through holes are formed in the left end and the right end of the rectangular pipe 8, reinforcing steel bars 1-1 extending out of the end of the concrete support rod 1 penetrate through the through holes in the rectangular pipe 8 to be fixed with the connecting seat 3, and the concrete support rod 1 is poured to achieve reliable combination of the concrete support rod 1 and the connecting seat 3.
