Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a mechanical connection device for a sonic logging pipe and a reinforcing cage. Background Technology

[0002] The sonic logging tube is the channel for ultrasonic testing of cast-in-place piles. It is pre-embedded inside the reinforcing cage and used to detect the integrity of the pile body (such as whether there are defects such as broken piles, slag inclusions, and voids). The installation quality directly affects the accuracy of the test results.

[0003] A search revealed Chinese patent CN220953568U, which discloses a fixing device for sonic logging pipes in bored piles. The device includes an outer ring of a reinforcing cage, with a sonic logging pipe body inside the outer ring. A connecting and fixing device connects the sonic logging pipe body and the outer ring of the reinforcing cage. This device includes a first fixing ring and a second fixing ring. A reinforcing bar is provided on the side of the first fixing ring, and the reinforcing bar is welded to the first fixing ring. A hook is provided at the top of the reinforcing bar and welded to the reinforcing bar. The end of the hook is attached to the outer ring of the reinforcing cage. The sonic logging pipe body is used for sonic logging pipe construction in pile foundation engineering. The sonic logging pipe body is connected and installed via the connecting and fixing device. This device, composed of a reinforcing bar, a first fixing ring, and a second fixing ring, is readily available, simple to manufacture, and enhances the construction quality of the sonic logging pipe body, accelerates construction efficiency, and conforms to the concepts of green construction and safe construction.

[0004] Based on the above search and existing technology, the findings were as follows:

[0005] The aforementioned patents require the installation of hooks at high altitudes, which is cumbersome and time-consuming. Furthermore, the opening direction of the hooks may conflict with the position of the reinforcing bars, making adjustments difficult and inefficient. In addition, multiple welding processes reduce the reliability of the hooks, and the reinforcing cage may deform during hoisting. Forced installation may cause the sonic logging tube to twist or the weld points to crack, thus presenting certain limitations. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a mechanical connection device for sonic logging pipes and reinforcing cages. The installation process is simple and efficient, avoiding loosening at the connection points and improving the construction quality of cast-in-place piles.

[0007] The technical solution to achieve the purpose of this utility model is: a mechanical connection device for a sonic logging tube and a steel cage, including longitudinal main bars, wherein multiple longitudinal main bars are provided, and a connection component is also included;

[0008] The first stiffening hoop is fixedly installed on the outside of the longitudinal main reinforcement, and multiple first stiffening hoops are provided;

[0009] The connecting assembly also includes a connecting end plate welded to one side of the longitudinal main reinforcement.

[0010] Preferably, a plurality of second stiffening hoops are fixedly installed on the inner side of the longitudinal main reinforcement, a pair of grouting pipes are provided on the inner side of the second stiffening hoops, and an acoustic logging pipe is sleeved inside the connecting end plate.

[0011] Preferably, a toothed anti-slip pad is provided between the connecting end plate and the sonic logging tube. The toothed anti-slip pad is provided at both ends of the connecting end plate. Fastening screws are threaded on both sides of the connecting end plate, and one end of the fastening screw abuts against the sonic logging tube.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] Firstly, the internal and external stiffening hoop arrangement of this utility model greatly improves the overall rigidity and deformation resistance of the steel cage, reduces the risk of displacement, detachment or damage of the grouting pipe during construction, ensures its final position is accurate, and guarantees the grouting effect.

[0014] Secondly, the connecting end plate of this utility model is pre-welded to the longitudinal main reinforcement, providing a firm and precise installation positioning point for the sonic logging pipe; the gasket increases the friction of the contact surface, effectively preventing the sonic logging pipe from rotating or sliding axially under vibration or external force; the threaded fastening screw can apply a large and adjustable locking force to firmly press the sonic logging pipe between the connecting end plate and the toothed gasket, ensuring that the sonic logging pipe remains stable and reliably connected throughout the construction process.

[0015] This method solves the problems of existing construction methods, which require installing hooks at high altitudes, which is cumbersome, time-consuming, and the hook opening direction may conflict with the position of the reinforcing bars, making adjustment difficult and inefficient. Furthermore, multiple welding reduces the reliability of the hooks, the reinforcing cage may deform during hoisting, and forced installation may cause the sonic logging tube to be twisted or the weld points to crack.

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved mechanical connection device for a sonic logging pipe and a reinforcing cage. The technical solution of this utility model is as follows:

[0025] like Figure 1 As shown, a mechanical connection device for a sonic logging pipe and a reinforcing cage includes longitudinal main bars 1, of which multiple longitudinal main bars 1 are provided to provide basic support for grouting work, and also includes connecting components.

[0026] The first stiffening hoop 2 is fixedly installed on the outside of the longitudinal main reinforcement 1. Multiple first stiffening hoops 2 are provided and connected with the main reinforcement to form a steel cage, thereby improving the stability of the building.

[0027] The connecting assembly also includes a connecting end plate 5 welded to one side of the longitudinal main reinforcement 1 to assist in the installation of the sonic logging pipe 4 and ensure that the sonic logging pipe 4 is firmly connected to the main reinforcement.

[0028] Furthermore, multiple second stiffening hoops 3 are fixedly installed on the inner side of the longitudinal main reinforcement 1, and a pair of grouting pipes 8 are provided on the inner side of the second stiffening hoop 3. A sonic logging pipe 4 is sleeved inside the connecting end plate 5. The grouting pipes 8 are tightly connected to the steel cage to prevent them from falling off.

[0029] Furthermore, a toothed anti-slip pad 6 is provided between the connecting end plate 5 and the sonic logging pipe 4. The toothed anti-slip pad 6 is provided at both ends of the connecting end plate 5. Fastening screws 7 are threaded on both sides of the connecting end plate 5. One end of the fastening screw 7 abuts against the sonic logging pipe 4. The toothed anti-slip pad 6 and the fastening screw 7 increase the friction between the connecting assembly and the sonic logging pipe 4, thus maintaining the firmness of the sonic logging pipe 4 on the reinforcing cage.

[0030] The specific working method is as follows: A reinforcing cage is formed by longitudinal main bars 1, first stiffening hoops 2, and second stiffening hoops 3. After the reinforcing cage is made, the connecting assembly is connected to the sonic logging tube 4. An opening is made on the connecting end plate 5, through which the connecting assembly can be opened. After the sonic logging tube 4 is inserted into the connecting end plate 5, the fastening screws 7 on both sides of the opening are tightened. In addition, toothed anti-slip pads 6 are installed on the upper and lower sides of the connecting end plate 5 to ensure that the sonic logging tube 4 is connected firmly. Then, the connecting end plate 5 is welded to the longitudinal main bars 1 on the reinforcing cage to ensure firmness and prevent detachment. According to the specifications, the length of the single-sided weld is 10d, and the length of the double-sided weld is 5d. The number of connections can be selected according to the connection situation.

[0031] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features.
