Description

Technical Field

[0001] The invention relates to a steel hanging box and belongs to the technical field of bridge construction. Background Art

[0002] The connection between the formworks of the steel hanging box adopts the conventional method: that is, it is connected by bolts. Each layer is assembled by 4 templates of the same size with rounded chamfers, and the blocks and layers are connected by bolts.

[0003] However, in practice, the bottom layer of formwork is constantly immersed in tidal water, and the numerous connecting bolts are prone to rust, making loosening and removal difficult. Initial formwork removal took over seven days, and the riverbed was located close to the bottom plate of the steel box. Tidal water drove silt to accumulate on the outside of the steel box, enveloping the bottom layer of formwork and hindering its removal. A common solution is to rent a long-arm excavator at low tide to desilt the bottom of the box, and then hire divers and equipment to remove the bolts underwater. This method is slow, time-consuming, costly, and has a low safety factor. Summary of the Invention

The slider 1236 is inserted into the long groove 1237, and the slider 1236 can move in the long groove 1237 along the left and right directions of the steel hanging box template 11.

[0031] To facilitate the connection of the bolt rod 1234 to the anchor bolt 121, in this embodiment, a connecting plate 1213 is provided on the clamping plate 1211, and a fixing nut 1235 is provided on the connecting plate 1213. A second through hole is formed in the connecting plate 1213, and the second through hole is located above the fixing nut 1235. The bolt rod 1234 passes through the second through hole and the fixing nut 1235 in sequence from top to bottom. The central axes of the first through hole and the second through hole overlap.

[0032] In order to facilitate the insertion of the anchor bolt 121 into the installation groove of the anchor plate 122, in this embodiment, the anchor plate 122 also includes a base plate 1221 installed on the steel hanging box template 11, and the positioning plate 1223 and the wedge block 1222 are installed on the base plate 1221 so that the two adjacent installation grooves are on the same straight line.

[0033] In this embodiment, the positioning plate 1223 is an L-shaped structure, and the mounting groove is formed by the positioning plate 1223 and the bottom plate 1221. The positioning plate 1223 also includes a connecting portion 12231 and a clamping portion 12232. The connecting portion 12231 is welded to the bottom plate 1221, and the bottom plate 1221, the connecting portion 12231, and the clamping portion 12232 form the mounting groove.

[0034] In order to enhance stability, in this embodiment, a triangular reinforcing rib (not shown) is connected between the clamping plate 1211 and the connecting plate 1213 .

[0035] Please refer to Figure 7 In this example, one end of the steel box template 11 is recessed inward to form a rounded chamfer. There are four steel box templates 11, which form a square steel box 1 with rounded corners. The steel box has three layers, with the connection components and pre-tightening components installed on the bottom layer.

[0036] Steel hanging box construction method: according to the steel hanging box design drawings, the steel hanging box template 11, connection components and pre-tightening components are manufactured. The steel hanging box is connected with two layers of steel hanging boxes in the height direction. Anchor plates 122 are installed between the bottom steel hanging box templates 11, and support plates 1231 are installed on the bottom steel hanging box templates 11, and the support plates 1231 are located in the height direction of the anchor plates 122. According to the steel hanging box design drawings, the concrete base plate 1221 is laid, the suspension system is set up, the bottom steel hanging box formwork 11 is hoisted to the concrete base plate 1221 for assembly, the base 1232 is installed on the support plate 1231, the jack and the top block are installed on the base 1232, the anchor bolt 121 is inserted into the two adjacent anchor plates 122, the anchor bolt 121, the base 1232 and the top block are connected through the bolt rod 1234, and the positioning nut 1233, the fixing nut 1235 and the nut on the top block are installed on the bolt rod 1234 at the same time. All nuts are pre-tightened to preliminarily connect the bottom steel hanging box formwork 11. The driving device drives the bolt rod 1234 to move upward, and the nuts on the base 1232 are pre-tightened for a second time to reinforce the bottom steel hanging box formwork 11. The driving device is depressurized to remove the nuts and driving device on the top surface of the top block. According to the steel hanging box design drawings, the remaining two layers of steel hanging box formwork 11 are hoisted on the bottom steel hanging box formwork 11. The two layers of steel hanging box formwork 11 above the bottom steel hanging box formwork 11 are connected by bolts, and the layers of the steel hanging box are connected by bolts. Lower the steel hanging box to the bottom of the water and seal the bottom of the bottom steel hanging box. After the construction inside the steel hanging box is completed, remove the two layers of steel hanging boxes on the bottom steel hanging box in turn, and then install the driving device and the nuts on the top surface of the top block on the base 1232. The driving device lifts the top block to drive the bolt rod 1234 to move upward to remove the nuts on the top surface of the base 1232. The driving device relieves pressure to remove all nuts, anchor bolts 121, pre-tightening components and the base 1232, and finally hoists away the bottom steel hanging box formwork 11.

[0037] To sum up: This application sets a connecting component and a pre-tightening component on the steel hanging box template, and fixes the steel hanging box by the cooperation of the connecting component and the pre-tightening component. Compared with the existing technology, the installation or removal of the steel hanging box is simple, which improves construction efficiency, improves the working environment, and effectively reduces construction costs.
