[0002] When constructing a box girder, first tie the bottom plate and web reinforcements. The web reinforcements are U-shaped reinforcements that are spaced along the longitudinal direction of the box girder. Then, the longitudinal reinforcements need to be passed through multiple web reinforcements along the longitudinal direction of the box girder and tied to the web reinforcements.

[0003] The inventors have found that due to the long longitudinal length of the box girder, the longitudinal reinforcement will bend to a certain extent when it is inserted, so the installation spacing of the reinforcement needs to be guaranteed. However, in the construction of the box girder reinforcement, the workers arrange the reinforcement randomly, which easily causes uneven installation spacing of the longitudinal reinforcement, thus affecting the construction quality of the box girder.

[0027] Please refer to Figure 1 The present embodiment provides a box girder reinforcement positioning tool 100, which includes a fixing frame 10 and a plurality of support ribs 20. The fixing frame 10 includes a bottom frame 11 for fixing a box girder bottom plate 201 and a side frame 12 for fixing a box girder web reinforcement 202. The plurality of support ribs 20 are spaced apart on the side frame 12 to support longitudinal ribs 203 installed on the box girder web reinforcement 202.

[0028] It is understandable that when the box girder 200 is constructed, the bottom plate 201 and the web reinforcement 202 are first tied, and the web reinforcement 202 is a U-shaped reinforcement arranged at intervals along the longitudinal direction of the box girder 200. Then, the longitudinal reinforcement 203 needs to be passed through the plurality of web reinforcements 202 along the longitudinal direction of the box girder 200 and tied with the web reinforcement 202. In other words, the box girder reinforcement positioning tool 100 provided in this embodiment is mainly used to position the longitudinal reinforcement 203 to ensure the installation spacing between the longitudinal reinforcements 203.

[0029] In order to facilitate the positioning of the longitudinal ribs 203 with reference to the support ribs 20 , in the present embodiment, the support ribs 20 protrude from the side frame 12 in a direction close to the box beam 200 .

[0030] Specifically, the web reinforcement 202 includes inner reinforcement 2021 and outer reinforcement 2022, and the longitudinal reinforcement 203 includes inner longitudinal reinforcement 2031 (not shown) and outer longitudinal reinforcement 203. The inner longitudinal reinforcement 2031 is tied to the inner reinforcement 2021, and the outer longitudinal reinforcement 203 is tied to the outer reinforcement 2022.

[0031] Furthermore, the distance that the support rib 20 protrudes from the side frame 12 is greater than or equal to the width of the web reinforcement 202 of the box girder 200. It can be understood that since the inner longitudinal rib 2031 and the outer longitudinal rib 203 are at the same height, the support rib 20 can position the inner longitudinal rib 2031 and the outer longitudinal rib 203 at the same time.

[0032] It should be noted that, in this embodiment, the box girder reinforcement positioning tool 100 is installed at both ends of the box girder 200 in the longitudinal direction. In other words, the box girder reinforcement positioning tool 100 of this embodiment is used to position both ends of the longitudinal reinforcement 203. In other embodiments, the box girder reinforcement positioning tool 100 can also be arranged at intervals along the longitudinal direction of the box girder 200 to prevent the longitudinal reinforcement 203 from falling in the middle position.

[0033] In order to adapt to different types of box girders 200, the spacing between the support ribs 20 is changed to adjust the spacing between the longitudinal ribs 203. In this embodiment, the support ribs 20 and the side frames 12 are detachably connected.

[0034] Specifically, the box girder reinforcement positioning tool 100 also includes a sleeve 30. The sleeve 30 is fixed to the side frame 12. In the present embodiment, the sleeve 30 can be fixed to the side frame 12 by welding. The axis of the sleeve 30 is consistent with the axis of the support rib 20, that is, the sleeve 30 should be installed horizontally as much as possible. The support rib 20 is installed on the side frame 12 through the sleeve 30. It can be understood that when the longitudinal rib 203 needs to be installed, the support rib 20 is passed through the sleeve 30, and the two ends of the longitudinal rib 203 are placed on the support rib 20 with reference to the position of the support rib 20, and the longitudinal rib 203 is tied to the web reinforcement 202; when the longitudinal rib 203 is installed, the support rib 20 only needs to be pulled out of the sleeve 30.

[0035] In order to ensure that the spacing between the support bars 20 is the same during the installation process, in this embodiment, the box girder reinforcement positioning tool 100 also includes a connecting bracket 40. The connecting bracket 40 connects multiple support bars 20. In this embodiment, the connecting bracket 40 is set obliquely and is located at the end of the support bar 20. In other embodiments, the connecting bracket 40 can be set vertically or located in the middle of the support bar 20, as long as multiple support bars 20 can be fixedly connected, the utility model is not limited.

[0036] Further, in order to ensure that the size of the fixing frame 10 is consistent with the size of the box beam 200, the side frame 12 is inclined relative to the bottom frame 11. The inclination angle of the side frame 12 relative to the bottom frame 11 is consistent with the inclination angle of the web reinforcement 202 of the box beam 200 relative to the bottom plate 201 of the box beam 200. It can be understood that the inner size of the fixing frame 10 is consistent with the outer size of the box beam 200, so that the fixing frame 10 can fit the box beam 200 when the box beam 200 is constructed.

[0037] Optionally, the material of the fixing frame 10 is angle steel, and the fixing frame 10 is made by welding multiple sections of angle steel. During specific construction, the fixing frame 10 can be processed according to the size of the box beam 200. The material of the support rib 20 is φ10 steel bar.

[0038] The working principle and process of the box beam reinforcement positioning tool 100 provided by the embodiment of the utility model are:

[0039] When constructing the box girder 200, firstly process the fixing frame 10 according to the design size of the box girder 200. Then tie the bottom plate 201 and the web reinforcement 202 on the fixing frame 10. The web reinforcement 202 is a U-shaped reinforcement arranged at intervals along the longitudinal direction of the box girder 200. Fix the support rib 20 on the fixing frame 10 so that it protrudes from the fixing frame 10 and the web reinforcement 202. Install the longitudinal reinforcement 203, place the two ends of the longitudinal reinforcement 203 on the support rib 20, and then tie the longitudinal reinforcement 203 and the web reinforcement 202. After the complete longitudinal reinforcement 203 is tied, remove the support rib 20 from the fixing frame 10 and proceed to the next step of construction.

[0040] The beneficial effects of the box girder reinforcement positioning tool 100 provided by the embodiment of the utility model are:

[0041] The box girder reinforcement positioning tool 100 of the utility model includes a fixing frame 10 and a plurality of support ribs 20. The fixing frame 10 includes a bottom frame 11 for fixing the bottom plate 201 of the box girder 200 and a side frame 12 for fixing the web reinforcement 202 of the box girder 200. The plurality of support ribs 20 are arranged at intervals on the side frame 12, and are used to support the longitudinal reinforcement 203 installed on the web reinforcement 202 of the box girder 200. The box girder reinforcement positioning tool 100, by installing a plurality of support ribs 20 on the fixing frame 10, the spacing between the plurality of support ribs 20 can be specifically set according to the construction requirements, so that the longitudinal reinforcement 203 can be installed and tied with reference to the position of the support ribs 20, thereby ensuring the installation spacing of the box girder 200 reinforcement and improving the construction quality of the box girder 200.

For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
