TECHNICAL FIELD
[0001] The utility model relates to the technical field of steel reinforcement cage manufacturing, in particular to a steel reinforcement cage mechanical connecting device. BACKGROUND
[0002] With the development of the construction industry, high-rise buildings and large-span bridges are increasing, and the application of building steel reinforcement is developing towards large diameter, dense arrangement and high strength. Purely using traditional steel reinforcement connection processes such as steel reinforcement binding, lap joint arc welding, flash butt welding and gas pressure welding cannot meet the construction needs. In the late 1980s, China began to promote steel reinforcement mechanical connection technology and developed corresponding industry standards. In the design documents, it has been required to use mechanical connection for steel reinforcement with a diameter of 25 mm or more.
[0003] However, from the perspective of construction quality, the steel reinforcement mechanical connection using the traditional construction method has the following shortcomings: 1. There is often a gap between the mechanical connection ends of two steel reinforcements, and the axial tension of the steel reinforcement after connection is reduced; 2. After the steel reinforcement is threaded, the semi-finished product is transported to the construction site for installation and connection. If the threaded ends of the steel reinforcement cage are not completely in the same section, the installation and connection efficiency is reduced, the waiting time for the next process is longer, and the safety risk is increased. SUMMARY
[0004] The utility model is made to solve the above technical problems, and aims to provide a steel reinforcement cage mechanical connection device that can effectively eliminate the gap between the mechanical connection ends of the steel reinforcement cage and control the quality of the steel reinforcement mechanical connection.
[0005] In order to achieve the above purpose, the utility model provides a steel reinforcement cage mechanical connection device arranged in a steel reinforcement cage seam welder for controlling the gap between the mechanical connection ends of the steel reinforcement cage. The steel reinforcement cage includes a plurality of longitudinal long main reinforcements and a plurality of longitudinal short main reinforcements. The seam welder includes a fixed rotary disc with a plurality of circular holes arranged on the fixed rotary disc. The connection device includes a flush plate and a connecting rod arranged on the flush plate, wherein,
[0006] The flush plate is parallel to the fixed rotary disc;
[0007] One end of the connecting rod is arranged on the flush plate, and the other end is arranged on the fixed rotary disc;
[0008] A customized pipe is arranged in the circular hole; wherein,
[0009] A flush bolt and a positioning bolt are arranged on the customized pipe;
[0010] The flush plate is used to control the longitudinal long main reinforcement in the same section;
[0011] The flush bolt is used to control the longitudinal short main reinforcement in the same section.
[0012] The positioning bolt is used to control the displacement of the longitudinal long main reinforcement and the longitudinal short main reinforcement in the processing.
[0013] Preferably, the thickness of the flush plate is the same as that of the fixed rotary disc.
[0014] Preferably, the connecting rod is perpendicular to the flush plate and the fixed rotary disc.
[0015] Preferably, the connecting rod is uniformly arranged between the flush plate and the fixed rotary disc.
[0016] Preferably, the connecting rod is welded and fixed on the flush plate and the fixed rotary disc.
[0017] Preferably, the shape and size of the flush plate are the same as those of the fixed rotary disc.
[0018] Preferably, the flush plate is a flush steel plate.
[0019] Preferably, a plurality of screw holes are arranged on the customized pipe, and the flush bolt and the positioning bolt are arranged in corresponding screw holes, respectively.
[0020] Preferably, the number of the screw holes is at least 2.
[0021] Preferably, the distance between the flush plate and the screw hole at the end of the customized pipe is 35d-500mm, wherein,
[0022] The d is the diameter of the reinforcement.
[0023] According to the above description and practice, the mechanical connecting device for the reinforcement cage can ensure the smooth and efficient operation process by keeping the flush plate parallel to the fixed rotary disc on the seam welder, and can ensure the stable installation of the flush plate and the accurate positioning of all longitudinal long main reinforcements in the same horizontal section. The flush bolt on the fixed rotary disc accurately acts on the longitudinal short main reinforcement, so that the longitudinal short main reinforcement can be arranged in the same section, thereby realizing the perfect alignment of the overall structure. The positioning bolt effectively locks the position of the main reinforcement in the processing of the longitudinal main reinforcement of the reinforcement cage, prevents any unnecessary deviation, and ensures the extreme pursuit of processing precision. The device realizes the reduction of the gap between the mechanical connection ends of the reinforcement cage by the precise cooperation of the flush plate, the connecting rod, the customized pipe, the flush bolt and the positioning bolt, and ensures the stability of the overall structure.

For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.
[0032] The traditional connecting device in the prior art has the problem that gaps often exist at the mechanical connecting ends of the two steels, resulting in reduced axial tension of the steel after connection.
[0033] The specific embodiments of the utility model will be described in detail below with reference to the drawings.
[0034] In this embodiment, a steel cage mechanical connecting device is disclosed, Figure 1 The entire three-dimensional structure of the steel cage mechanical connecting device is shown. Figure 2 The connecting structure without the steel cage mechanical connecting device is shown. Figure 3 The steel mechanical connecting structure with the steel cage mechanical connecting device is shown.
[0035] Please refer to Figures 1 to 3 In the utility model, the steel cage mechanical connecting device comprises: a flush plate 1 and a connecting rod 2 arranged on the flush plate 1, wherein the steel cage comprises a plurality of longitudinal long main steels and a plurality of longitudinal short main steels; the flush plate 1 is parallel to the fixed rotating disc on the seam welder; one end of the connecting rod 2 is arranged on the flush plate 1, and the other end is arranged on the fixed rotating disc; a plurality of round holes are arranged on the fixed rotating disc, and a customized pipe 3 is arranged in the round hole; wherein flush bolts and positioning bolts are arranged on the customized pipe 3; the flush plate 1 is used for controlling the longitudinal long main steels in the same section; the flush bolts are mainly used for controlling the longitudinal short main steels in the same section, so that they can be arranged in the steel cage in an orderly and uniform manner; and the positioning bolts are used for locking the positions of the longitudinal long main steels and the longitudinal short main steels during the processing of the longitudinal long main steels and the longitudinal short main steels, so as to prevent deviation caused by vibration or external force. After cutting the main steel end, threading the steel, and polishing the threaded end, the main steel is moved through the corresponding hole of the rotating disc of the seam welder, reaches the corresponding steel plate round hole of the fixed rotating disc, and then is inserted into the customized pipe 3, the longitudinal short main steel is tightened against the bolt, and the longitudinal long main steel is tightened against the flush steel plate. After all the longitudinal long main steels are in place, the bolts are tightened in sequence. The end of the coil steel (winding steel) is first welded on a main steel, and then the winding steel is wound on the main steel by rotating the fixed rotating disc and the moving rotating disc (the moving disc rotates and moves backward at the same time), and welding is performed at the same time, so as to form the product steel cage.
[0036] As Figure 3 As shown in the prior art, the steel cage is mechanically connected by a sleeve, if the installation precision is insufficient, gaps exist between the two opposite steels in the sleeve 6, which leaves hidden dangers for engineering quality. Compared with the steel cage mechanical connection in the prior art, the steel cage mechanical connecting device in the utility model solves the problem that the main steel joint section is not flush during the processing of the current steel cage. As Figure 1The device has the advantages that all the longitudinal long main reinforcement and longitudinal short main reinforcement are respectively arranged in the same section through the flush plate 1 and flush bolt, the two opposite steels are tightly connected in the sleeve 6 when the sleeve mechanical connection is adopted, and the engineering quality is ensured.
[0037] The flush plate 1 has the same thickness as the fixed rotary disc, the installation speed of the engineering is ensured, and the mechanical connection quality of the steel is ensured.
[0038] The connecting rod 2 is perpendicular to the flush plate 1 and the fixed rotary disc, the flush plate 1 is parallel to the fixed rotary disc, the parallel design not only ensures the stability of the operation process, but also greatly improves the processing efficiency.
[0039] The connecting rod 2 is uniformly arranged between the flush plate 1 and the fixed rotary disc, so that the overall support and accurate positioning of the steel cage are realized.
[0040] The connecting rod 2 is welded and fixed on the flush plate 1 and the fixed rotary disc, the welding not only ensures the firmness of the connection, but also does not affect the material performance, so that the flush plate 1 and the fixed rotary disc can be connected as a whole through the connecting rod 2 and work cooperatively.
[0041] The flush plate 1 and the fixed rotary disc are the same in size, the flush plate 1 and the fixed rotary disc are consistent in thickness and are accurately matched in size. The same size further enhances the cooperation degree between the two, reduces the friction and wear caused by size deviation, and improves the precision and efficiency of the whole device.
[0042] The flush plate 1 is a flush steel plate. The flush plate 1 is made of high-strength flush steel plate, and the surface is specially treated to increase wear resistance and corrosion resistance, so as to ensure stability and reliability during long-term use.
[0043] A plurality of screw holes are arranged on the customized pipe 3, and the flush bolt and the positioning bolt are arranged in the screw holes. The number of screw holes is at least 2. The number of screw holes can be adjusted according to specific requirements, so as to adapt to steel cages of different specifications and sizes, so as to ensure that the bolts can bear uniform stress, and improve the stability and durability of the whole device.
[0044] The distance between the flush plate 1 and the endmost screw hole is 35d-500mm, wherein d is the diameter of the steel.
[0045] In the existing pile steel reinforcement cage processing process, the steel reinforcement cage mechanical connecting device is used, the steel reinforcement cage thread end can be completely controlled in the same section in the steel field, the on-site installation connection time is greatly improved, the on-site installation speed is fast, and the safety risk caused by long pile foundation hole forming waiting time can be reduced. After the steel reinforcement cage semi-finished product processed by the device is transported to the site, the installation time of two steel reinforcement cages is about 20 minutes, and the installation time of two steel reinforcement cages processed by the ordinary process is about 1 hour, the crane and labor time is saved, and the construction cost is greatly reduced. The device has a wide application range, and can be used for mechanical connection construction of various types of steel bars.
