For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. Example 1
[0034] like Figure 1 As shown, an adaptive steel bar clamp for an arch seat includes a clamp plate 100, and a plurality of steel bar grooves 110 are spaced apart on one side of the clamp plate 100 along the length direction, which can match the insertion of the arch seat steel bar from one side of the clamp plate 100, and the spacing is consistent with the spacing between the arch seat steel bars, so as to help position the arch seat steel bars. At least two clamp plate oblong holes 120 are spaced apart on the other side of the clamp plate 100 along the length direction, and the length direction of the clamp plate oblong holes 120 is consistent with the width direction of the clamp plate 100, and the spacing matches the spacing of the bolt holes of the arch seat template. The centers of the clamp plate oblong holes 120 are generally arranged in a straight line. If the thickness of the steel bar protective layer in the corresponding arch seat section is consistent, then the center line of the clamp plate oblong holes 120 is parallel to the long side of the clamp plate 100. The clamp plate 100 can be made of steel plate. For example, in this embodiment, it is made of 8mm thick steel plate. The size can be determined according to needs. In this embodiment, 0.2m*1m is used.
[0035] Furthermore, there are at least two fixture plate oblong holes 120, and at least one of the long sides is marked with fixture plate scale lines (not shown in the figure). Through the fixture plate scale lines, it is convenient to confirm that the fixture fixing bolt 300 is installed at the appropriate position of the fixture plate oblong hole 120 during fixing. If the thickness of the steel bar protective layer in the corresponding arch seat section is consistent, the fixture plate scale lines can be used to quickly identify the specific position of the fixture fixing bolt 300 in the fixture plate oblong hole 120, and multiple fixture fixing bolts 300 can be installed at the corresponding scale line positions in the fixture plate oblong hole 120.
[0036] Combination Figure 2 and Figure 3 As shown, when in use, first install a layer of arch seat template 400, install the fixture fixing bolt 300 in the bolt hole of the arch seat template at the top of the installed arch seat, the head of the fixture fixing bolt 300 is at the bottom, the screw rod passes through the top steel plate of the arch seat upward, and then the oblong hole 120 of the fixture plate is matched and inserted into the fixture fixing bolt 300. According to the thickness of the steel bar protective layer, refer to Figure 2 Move the fixture plate 100 left and right in the direction shown, adjust the relative position of the fixture fixing bolt 300 in the oblong hole of the fixture plate, and after the adjustment is completed, screw the fixture fixing bolt 300 into the fixture fixing nut to fix the fixture plate 100. According to the length of the arch seat template 400, a sufficient number of steel bar fixtures can be assembled according to the above steps. In this embodiment, an oblong hole of the fixture plate corresponding to the bolt hole of the arch seat template is provided. By fixing the fixture plate 100 on the arch seat template 400, it is not necessary to use a steel frame to fix the steel bar fixture, which reduces the waste of materials and avoids the trouble of processing different steel frames due to different heights of the arch seat template. At the same time, since the oblong hole of the fixture plate has a certain length, it can be adjusted left and right to meet the requirements of the arch seat steel bar binding of steel bar protective layers of different thicknesses, which can reduce the number of fixtures configured and also reduce material waste. Example 2
[0037] like Figure 4 As shown, an adaptive steel bar clamp for an arch seat includes a clamp plate 100 and a fixing seat 200, wherein: Figure 5 As shown, a plurality of steel bar grooves 110 are provided at intervals on one side of the fixture plate 100 along the length direction, which can match the insertion of the abutment steel bars from one side of the fixture plate 100, and the spacing is consistent with the spacing between the abutment steel bars, thereby helping to position the abutment steel bars. Figure 6-7As shown, the fixing seat 200 includes a fixing plate 210 and a clamping plate 220. The fixing plate 210 is connected to a clamping plate 220 on the top and bottom of one side along the length direction, respectively. The spacing between the two clamping plates 220 can match the other side of the fixture plate 100 inserted; the fixing plate 210 is provided with at least two fixing seat oblong holes 230 at intervals on the other side along the length direction, and the spacing of the fixing seat oblong holes 230 matches the spacing of the bolt holes of the arch seat template. Due to the different arch seat steel bars, sometimes different fixture plates 100 need to be processed to set steel bar grooves 110 with different spacings. By adopting the form of the fixing seat 200, the width of the fixture plate 100 can be reduced, and the material consumption of the fixture plate 100 can be reduced. The fixing seat 200 does not need to be replaced, and a suitable fixture plate 100 can be inserted when in use. After completing this project, the above-mentioned steel bar fixture can also be transferred to other projects for continued use, especially the fixing seat 200 can be reused many times.
[0038] The fixture plate 100, the fixing plate 210 and the clamping plate 220 can be made of steel plates. For example, in this embodiment, the fixture plate 100 and the fixing plate 210 are made of 8 mm thick steel plates, and the clamping plate 220 can be made of 8 mm thick steel plates or thinner steel plates. The size can be determined as needed, such as the fixture plate 100 and the fixing plate 210 are 0.1m*1m, and the clamping plate 220 is 0.08m*1m. The fixing plate 210 and the clamping plate 220 can be fixed by welding.
[0039] Furthermore, the length of the fixing plate 210 and the clamping plate 220 is less than or equal to the clamping plate 100. This design takes into account that during installation, multiple steel bar clamps are required to be installed on the arch seat formwork 400. If the length of the fixing plate 210 and the clamping plate 220 is too large, it will affect the installation of other steel bar clamps.
[0040] Furthermore, there are at least two oblong holes 230 of the fixing seat, and a fixing plate scale line is marked on at least one side of the long sides to facilitate and quickly realize the positioning of the fixture fixing bolt 300.
[0041] In addition, in order to better fix the fixture plate 100 and the clamping plate 220, fixture plate through holes and clamping plate through holes may be correspondingly provided in the fixture plate 100 and the clamping plate 220, and then fastened by bolts and nuts.
[0042] The installation process of the steel bar clamp of this embodiment is similar to that of the first embodiment, except that before the steel bar clamp is inserted into the clamp fixing bolt 300, the clamp plate 100 is pre-inserted between the two clamping plates 220 and close to the fixing plate 210, and then subsequently fixed to the arch seat formwork 400. Example 3
[0043] This embodiment is similar to the second embodiment, except that the fixing plate 210 replaces the fixing clamping structure 240 and is matched with a fixing connecting bolt 260 and a fixing connecting nut.
[0044] Combination Figure 8-11 As shown, the top and bottom surfaces of one side of the fixed plate 210 along the length direction are respectively connected with multiple groups of fixed clamping structures 240 at intervals, and each group of fixed clamping structures 240 includes two clamping bars, wherein the bottom surface of one clamping bar is connected to the top surface of the fixed plate 210, and the top surface of the other clamping bar is connected to the bottom surface of the fixed plate 210, and the spacing between the two clamping bars can match the other side of the inserted fixture plate 100, and at least two groups of fixed clamping structures 240 are penetrated by clamping structure through holes 250, and at least two fixture plate through holes are penetrated at intervals on the other side of the fixture plate 100 along the length direction, and the positions of the clamping structure through holes 250 match the positions of the fixture plate through holes, and the fixed connecting bolts 260 can pass through the clamping structure through holes 250 and the fixture plate through holes and be tightened by the fixed connecting nuts to fix the fixed clamping structures 240 and the fixture plate 100 together; the other side of the fixed plate 210 along the length direction is vertically spaced with multiple fixed seat oblong holes 230. Compared with the clamping structure using the clamping plate 220 , the clamping strip can further reduce the amount of material used.
[0045] Furthermore, the length of the fixing plate 210 is less than or equal to that of the fixture plate 100, and the fixing clamping structure 240 does not exceed the side of the fixing plate 210 along the width direction to avoid affecting the installation of other steel bar fixtures.
[0046] Furthermore, there are at least two oblong holes 230 of the fixing seat, and a fixing plate scale line is marked on at least one side of the long sides to facilitate and quickly realize the positioning of the fixture fixing bolt 300.
[0047] The installation process of the steel bar clamp of this embodiment is similar to that of the second embodiment. After the clamp plate 100 is inserted into the fixed clamping structure 240, the clamp plate 100 is first fixed to the fixed clamping structure 240 with the fixed connecting bolts 260 and the fixed connecting nuts, and then the subsequent operation of fixing it to the arch seat formwork 400 is performed.
