[0002] The steel cage can restrain the prefabricated segment concrete, enabling it to withstand a certain horizontal force and improve its tensile performance. It is widely used in construction and tunnel and underground engineering fields. When making the steel cage, workers generally use iron wire to make a steel cage skeleton, and then use carbon dioxide shielded welding to weld the steel bars. However, when welding the existing steel cage, the steel bars are prone to shaking, and multiple workers are required to hold the steel bars steady while welding. Therefore, it brings great inconvenience to the workers and consumes physical and manpower.

[0003] The prior art CN116713677A discloses a steel bar fixing device for welding steel bar cages, which is implemented by placing the steel bar cage on the lower support seat, and then rotating the corresponding upper fixing seat to clamp the steel bar cage, and controlling the electric push rod to extend and retract so that the hook is clamped into the clamping seat, thereby achieving fixed clamping of the steel bar cage, ensuring that the steel bar cage remains stable during the welding process, which is beneficial to improving the welding effect, and the rotating shaft is driven to rotate by the first double-headed motor, and the rotating shaft drives the first bidirectional screw to rotate through the cooperation of the first bevel gear and the second bevel gear, and the first bidirectional screw drives the corresponding sliding plate to slide, and the sliding plate drives the bearing plate to move up and down through the connecting plate and the connecting seat, so as to facilitate the adjustment of the height of the lower support seat and the fixed steel bar cage, which is beneficial to the staff to weld the steel bar cage and improve the welding work efficiency, and is beneficial to the staff to put the steel bar cage into the lower support seat or remove it from the lower support seat, further improving the work efficiency.

[0004] However, when the above-mentioned positioning device is used to weld the steel cage, the steel bar spacing is generally fixed by the support plates on both sides of the base above the base.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0026] First embodiment:

[0027] See also Figures 1 to 3 The present invention provides a device for fixing the spacing of a segment reinforcement cage, comprising a base 101, a supporting mechanism, a fixing plate 102, a supporting frame 103, a first supporting plate 104, a second supporting plate 105 and a fixing rod 106, wherein the supporting mechanism comprises a mounting plate 107 and a supporting rod 108, wherein the mounting plate 107 and the supporting rod 108 are connected by a limiting member, and the limiting member comprises a limiting bolt 109 and a limiting nut 110.

The steel bars are supported by the second supporting plate 105 and the fixing rod 106, so that the outer layer of the steel cage can be installed. During the installation of the steel cage, the fixing plate 102, the first supporting plate 104 and the second supporting plate 105 are used in coordination to ensure the spacing at the bottom, both sides and the middle of the steel bars. At the same time, the steel cage spacing fixing device has a simple structure, is easy to manufacture, safe and reliable, thereby reducing the labor intensity of workers and improving work efficiency, thereby ensuring the processing quality of the steel cage and improving the work efficiency of construction. The existing positioning device generally fixes the steel cage spacing by the two side support plates of the base 101 above the base 101 when welding the steel cage. This method can only ensure the spacing at the bottom and both sides of the steel bars, but cannot ensure the spacing at the middle of the steel bars. In addition, it will greatly waste welding time during welding, and the technical requirements for workers are particularly high. In addition, the labor intensity is high and fatigue is easy, which increases the processing and production costs. Technical problems.

[0029] Among them, the supporting mechanism is located on the base 101, and is used to support the fixed plate 102. The number of the fixed plates 102 is two, and they are symmetrically arranged on the left and right sides above the base 101. The supporting frame 103 is evenly arranged on the base 101. The first supporting plate 104 is arranged on the supporting frame 103. The number of the first supporting plates 104 is two, and they are symmetrically arranged on the left and right sides above the base 101, and the two first supporting plates 104 are located between the two fixed plates 102. The second supporting plates 105 are evenly distributed on the first supporting plates 104, and each of the second supporting plates 105 is provided with a plurality of fixing rods 106.

[0031] Again, the mounting plate 107 is arranged on the base 101, and the support rod 108 is disassembled and arranged between two opposite and adjacent mounting plates 107, and the support rod 108 is arranged below the fixed plate 102. The mounting plate 107 and the support rod 108 are connected by a limit piece to realize the disassembly of the support rod 108, so as to achieve the purpose of disassembling the fixed plate 102.

A plurality of second steel bar grooves 113 are distributed on the second support plate 105, and a fixing rod 106 is arranged near each of the second steel bar grooves 113.

[0034] Finally, a plurality of first steel bar grooves 112 are evenly distributed on the fixed plate 102 and the first support plate 104, the number of the first steel bar grooves 112 of the fixed plate 102 and the first support plate 104 are the same, and the positions of the first steel bar grooves 112 of the fixed plate 102 and the first steel bar grooves 112 of the first support plate 104 correspond one to one, and the same steel bar is inserted into the first steel bar grooves 112 at the corresponding positions of the fixed plate 102 and the first support plate 104.

[0035] When using the device for fixing the spacing of the steel cage of the pipe segment according to the present embodiment, a plurality of the support rods 108 are inserted in sequence between the two oppositely and adjacently arranged mounting plates 107 at corresponding positions. When the support rods 108 are in contact with the base 101, the through holes of the support rods 108 will be aligned with the through holes of the mounting plates 107 at corresponding positions. At this time, the limiting bolts 109 are inserted into the through holes of the support rods 108 and the mounting plates 107, and then the limiting nuts 110 are sleeved outside the limiting bolts 109, so that the limiting nuts 110 move along the trajectory of the threads outside the limiting bolts 109, so that the limiting nuts 110 can be tightened outside the limiting bolts 109, so that the support rods 108 can be limited and fixed in the mounting plates 107 at corresponding positions, and then the fixing plates 102 can be limited and fixed above the base 101, thereby realizing the installation of the fixing plates 102 on the base 101.

[0036] After installing the fixing plate 102, several steel bars are sequentially inserted into the first steel bar grooves 112 at several corresponding positions on the fixing plate 102 and the first support plate 104, so as to realize the installation of the inner layer of the steel cage.

[0037] In summary, the steel bars are supported by the fixing plate 102 and the first supporting plate 104, so that the inner layer of the steel cage can be installed. The steel bars are supported by the second supporting plate 105 and the fixing rod 106, so that the outer layer of the steel cage can be installed. During the installation of the steel cage, the spacing at the bottom, both sides and the middle of the steel bars is guaranteed by the coordinated use of the fixing plate 102, the first supporting plate 104 and the second supporting plate 105. At the same time, the steel cage spacing fixing device has a simple structure, is easy to manufacture, safe and reliable, thereby reducing the labor intensity of workers and improving work efficiency, thereby ensuring the processing quality of the steel cage and improving the work efficiency of construction. The existing positioning device generally fixes the steel cage spacing by the two side support plates of the base 101 above the base 101 when welding the steel cage. This method can only ensure the spacing at the bottom and both sides of the steel bars, but cannot ensure the spacing at the middle of the steel bars. Moreover, it will greatly waste welding time during welding, and the technical requirements for workers are particularly high. In addition, the labor intensity is high and fatigue is easy, which increases the processing and production costs. Technical problems.
