Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction engineering, in particular to an anti-floating anchor rod for construction engineering. Background Art
[0002] Anti-floating anchor rods are a kind of anti-floating measure for underground structures in construction projects. Anti-floating anchor rods are different from general foundation piles and have their own unique properties. The biggest difference between them and general foundation piles is that foundation piles are usually compression piles, and the pile body bears the pressure of the building load. The force is transmitted from the top of the pile to the bottom of the pile, and the force on the pile body changes with the change of the building load; while anti-floating piles are pull-out piles that bear tensile force. The force of ordinary anti-floating piles is also transmitted from the top of the pile to the bottom of the pile. The force on the pile body changes with the change of the groundwater level, but the force mechanisms of the two are exactly opposite. The following problems exist in the existing technology:
[0003] Because anti-floating anchor rods are often made of longer steel bars and inserted into pre-drilled holes, and then cement mortar is poured to complete solidification. However, due to the relatively simple structure of existing anti-floating anchor rods, they cannot be guaranteed to be stably located in the center of the hole when inserted into the hole, resulting in the problem that the position of the anti-floating anchor rod is easily offset when pouring cement mortar. Utility Model Content
[0004] The utility model provides an anti-floating anchor rod for construction engineering to solve the problems raised in the above background technology.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0006] An anti-floating anchor rod for construction engineering comprises an anchor rod steel bar, a placing head is fixedly installed on the bottom outer wall of the anchor rod steel bar, a positioning plate is penetrated through the upper outer wall of the anchor rod steel bar, a steel bar through-hole is penetrated through the middle outer wall of the positioning plate, a wear-resistant layer is fixedly installed on the inner wall of the steel bar through-hole, the outer wall of the wear-resistant layer overlaps the outer wall of the anchor rod steel bar, a positioning ring is fixedly installed on the bottom outer wall of the positioning plate, and conical nails are evenly fixedly installed on the bottom edge outer wall of the positioning plate.
[0007] A further improvement of the technical solution of the utility model is that: spring buckles are fixedly installed on the inner cavities of the left and right outer walls of the positioning ring, and a pressure plate is fixedly installed on the top outer wall of the spring buckle.
[0008] A further improvement of the technical solution of the utility model is that a beveled edge clamping plate is fixedly installed on the front outer wall of the pressure plate, and the outer wall of the beveled edge clamping plate penetrates the side outer wall of the positioning ring.
[0009] By adopting the above technical solution, through the mutual cooperation between the spring buckle, the pressure plate and the bevel pressure plate in the solution, when the positioning ring is inserted into the hole for inserting the anti-floating anchor rod, the bevel clamping plate will be squeezed, thereby making the positioning ring more stably inserted.
[0010] A further improvement of the technical solution of the utility model is that a grouting pipe hole is provided through the outer wall of the positioning ring, the grouting pipe hole is located on one side of the steel bar perforation, and a grouting pipe is clamped on the inner wall of the grouting pipe hole.
[0011] By adopting the above technical solution, through the mutual cooperation between the grouting pipe hole and the grouting pipe in the solution, the positioning plate will not affect the pouring of cement mortar after installation, and by pulling out the grouting pipe upward while pouring, it is finally possible to observe whether it is full through the grouting pipe hole.
[0012] A further improvement of the technical solution of the utility model is that pulley support rods are evenly and fixedly installed in the inner cavity of the positioning plate.
[0013] A further improvement of the technical solution of the utility model is that a pulley is movably mounted on the outer wall of the top end of the pulley support rod, the outer wall of the pulley penetrates the inner wall of the grouting pipe hole, and the outer wall of the pulley overlaps the outer wall of the grouting pipe.
[0014] By adopting the above technical solution, through the mutual cooperation between the pulley support rod and the pulley in the solution, the friction between the grouting pipe and the grouting pipe hole is reduced when the grouting pipe is pulled upward, thereby reducing wear and making the pulling process smoother.
[0015] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:
[0016] 1. The utility model provides an anti-floating anchor rod for construction engineering, which adopts the cooperation of anchor rod steel bars, placing heads, positioning plates, steel bar perforations, conical nails and positioning rings. The anchor rod steel bars are passed through the positioning plates by using the steel bar perforations, and then the placing heads at the lower end are put into the holes drilled in advance. Then the positioning ring at the bottom of the positioning plate is inserted into the holes, and the positioning plate is firmly fixed to the ground by using conical nails. Then the anchor rod steel bars are continuously moved downward until they reach the bottom. This solves the problem that the existing anti-floating anchor rods cannot be stably located in the center of the holes when inserted into the holes due to their relatively simple structure, resulting in the problem that the position of the anti-floating anchor rods is easily offset when pouring cement mortar. This achieves the effect of keeping the anchor rod steel bars in the center before grouting to prevent offset.
[0017] 2. The utility model provides an anti-floating anchor rod for construction engineering, which adopts the cooperation of a positioning plate, a grouting pipe hole and a grouting pipe. After the positioning plate is fixed, the grouting pipe is inserted into the grouting pipe hole and extended to the bottom of the prefabricated hole, and then cement mortar is injected into the hole through the grouting pipe. At the same time, it is pulled out upward while injecting until it is completely pulled out. It can be observed through the grouting pipe hole whether it is full, so that the anchor rod reinforcement is positioned without hindering the grouting operation, and the cement mortar is prevented from overflowing, which is more convenient to use.
