Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1 to 6, the asymmetric lattice load box through long rib 2 conversion and reinforcement connector comprises a sleeve 1, through long ribs 2 and an annular barrier sheet 3. The bottom of sleeve 1 passes lower lattice 5 and with the lower surface fixed connection of lower lattice 5, sleeve 1 is open-ended cavity in top to with last lattice 4 butt, the internal surface of sleeve 1 is the heliciform surface structure.
Lead to long muscle 2 and be steel bar structure, lead to the top of long muscle 2 and pass last lattice 4 and be connected with the last fixed surface of last lattice 4, lead to in long muscle 2's the bottom is gone deep into sleeve 1, lead to the surface of long muscle 2 and have the external screw thread (not shown in the figure). Wherein the upper lattice 4 has a threaded hole (not shown in the figure) and the through ribs 2 are fitted into the threaded hole provided in the upper lattice 4. The mode of the bolt connection of the through long ribs 2 and the upper lattice 4 is convenient to disassemble and assemble to meet the requirements of different engineering environments, and the bolt connection mode can be replaced by a welding connection fixing mode.
Wherein the diameter of the through long rib 2 is smaller than the diameter of the opening of the sleeve 1, so that the through long rib 2 can freely move up and down in the sleeve 1.
As shown in fig. 1, the conventional product has no through long ribs 2. When the foundation pile is poured with concrete, the asymmetric lattice load box is filled with concrete. During liquid injection and pressurization, a piston in the oil cylinder 6 displaces to cause a fracture layer 7 to form an upper pile body 8 and a lower pile body 9, and load is transmitted to the asymmetric lattice load box through the upper reinforcement cage 10 and cannot be effectively transmitted to the lower reinforcement cage 11, so that the bearing capacity of the foundation pile is seriously influenced.
As shown in fig. 2. The through long rib 2 conversion reinforcing connecting piece is installed in the asymmetric lattice load box, and the top of the through long rib 2 is screwed into a threaded hole in the upper lattice 4 to form firm connection for reinforcing the upper lattice 4, and the upper lattice 4 is welded with an upper steel 8 rib cage 10 of the asymmetric lattice load box to form rigid connection. The sleeve 1 extends into the lower lattice 5 of the asymmetric lattice load box, and a firm connection for reinforcing the lower lattice 5 is formed, and the lower lattice 5 is welded with the lower reinforcement cage 11 of the asymmetric lattice load box to form a rigid connection and fixation. Lead to 2 bottoms of long muscle to stretch into to sleeve 1 bottom, annular separation piece 3 is located sleeve 1 opening part, plays the closure effect to sleeve 1 opening for cement paste gets into in sleeve 1 when preventing to detect preceding foundation pile construction.
As shown in fig. 3, when the concrete is poured into the foundation pile, the asymmetric lattice load box is filled with the concrete. When liquid injection pressurization is carried out, the piston in the oil cylinder 6 displaces to cause the occurrence of a fracture layer 7, at the moment, the upper lattice 4 drives the through long rib 2 to move upwards, and the through long rib 2 drives the annular blocking sheet 3 to move upwards together. The annular barrier 3 no longer closes the sleeve 1 at this time, so that the grout 13 can enter the sleeve 1 when the next grouting reinforcement 12 is performed.
As shown in fig. 4-6, when grouting reinforcement 12 is performed in the asymmetric lattice load box, the grout 13 will automatically fill the fracture layer 7 and flow into the sleeve 1 through the opening of the sleeve 1, i.e. the opening of the sleeve 1 is the grout inlet 14. Because the inner wall of sleeve 1 is thread structure to be convenient for bond after slip casting reinforcement 12, simultaneously because the surface that leads to long muscle 2 has the external screw thread, behind slip casting reinforcement 12, can effectual and sleeve 1 rigid connection. Thereby formed the steel reinforced concrete structure, can effectually pass power to lower steel reinforcement cage 11 with the load through last steel reinforcement cage 10, promoted the foundation pile bearing capacity of the stake of being examined, ensured can satisfy the operation requirement of engineering stake.
The height of the through long rib 2 extending into the sleeve 1 is not less than the stroke height of the oil cylinder 6 in the asymmetric lattice load box after being stressed, so that the bottom of the through long rib 2 is still positioned in the sleeve 1 when the through long rib 2 moves upwards along with the upper lattice 4, and the stroke of the oil cylinder 6 in the asymmetric lattice load box is not limited.
In order to improve the load effect of the upper and lower cages 10, 11 on continuous through-length transfer, the through-length bars 2 are converted into a plurality of reinforcing connectors, which are evenly distributed around the asymmetric lattice load box.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
