Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a reinforcement device for steel formwork used in the casting of cylindrical bridges. Background Technology

[0002] Bridge columns are important vertical load-bearing components in bridge structures. They generally refer to columns with circular cross-sections in bridge piers. They mainly bear the loads from the bridge superstructure and transfer them to the foundation and subgrade to ensure the stability and safety of the bridge. During construction, they are formed by pouring concrete using cylindrical cast-in-place steel formwork. To prevent bulging or other problems caused by inadequate formwork reinforcement during the concrete forming process, reinforcement devices are installed on the outside of the formwork.

[0003] Existing reinforcement devices typically use steel hoops to reinforce the outside of the formwork. However, when reinforcing cylindrical formwork of different diameters, it is necessary to make corresponding matching steel hoops separately, which is very troublesome and has great limitations in use. In addition, most steel hoops are for single use, which greatly reduces the utilization rate. Utility Model Content

[0011] It facilitates centering and automatic alignment while conveniently compensating for dimensional errors.

[0012] Preferably, the inclined surface of the support block is provided with an anti-slip pad.

[0018] Preferably, a limiting plate is fixedly connected to the bottom of the inner wall of the mounting groove by bolts, the right side wall of the limiting plate extends to the outside of the mounting groove, and the bottom of the limiting plate contacts the top of the hexagonal nut.

[0019] It can limit the position of the hexagonal nut, thereby improving the fixing effect.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example: Figures 1-5As shown, this utility model provides a technical solution for a bridge cylindrical casting steel formwork reinforcement device, including a hollow plate 100. There are two hollow plates 100, and the two hollow plates 100 are arranged symmetrically on the left and right sides. The inner cavity of the hollow plate 100 is provided with a support component 200. The front and rear side walls of the left hollow plate 100 are provided with a first fixing port 120, and the inner cavity of the first fixing port 120 is provided with a fixing component 300.

[0031] Please refer to this carefully. Figures 1-4 The support assembly 200 includes limiting blocks 210. The inner wall of the hollow plate 100 has grooves 110 at its top and bottom. The limiting blocks 210 are slidably connected between the inner walls of the upper and lower grooves 110. There are two limiting blocks 210, symmetrically arranged on the front and rear sides of the inner cavity of the grooves 110. Connecting blocks 211 are fixedly connected to the inner walls of the left and right limiting blocks 210, and are slidably connected to the inner walls of the hollow plate 100. The inner walls of the connecting blocks 211 extend to the outer side of the hollow plate 100 and are fixedly connected to supporting blocks 212. Positioning rods 213 are fixedly connected to the outer walls of the left and right limiting blocks 210. Fixing plates 220 are fixedly connected to the outer walls of the left and right hollow plate 100 by bolts. The inner wall of the 0 has insertion holes 221, which are evenly distributed from front to back. The end of the positioning rod 213 extends into the inner cavity of the insertion hole 221 and engages with the inner wall of the insertion hole 221. The inner walls of the front and rear support blocks 212 are provided with inclined surfaces, and the inclined surfaces of the support blocks 212 are provided with anti-slip pads. This kind of bridge cylindrical casting steel formwork reinforcement device uses the support component 200 in conjunction with the fixing plate 220 and the insertion holes 221, and then uses the hollow plates 100 on both sides to reinforce and support the formwork. It can adapt to formwork of different sizes, so that it is not necessary to make a matching one each time the formwork is reinforced. It is more convenient and greatly expands the scope of use. After use, it can be reused, which greatly improves the utilization rate.

[0032] Please refer to this carefully. Figures 1-5The fixing component 300 includes a rotating block 310, which is rotatably connected between the top and bottom of the inner cavity wall of the first fixing port 120 via a pin. A fixing screw 311 is fixedly connected to the right side wall of the rotating block 310. The front and rear side walls of the right hollow plate 100 have a second fixing port 121. The right end of the fixing screw 311 passes through the second fixing port 121 and is slidably connected to the inner cavity wall of the second fixing port 121. A hexagonal nut 312 is screwed onto the outer side wall of the fixing screw 311. The hexagonal nut 312 is located on the right side of the right hollow plate 100. Mounting grooves are opened on the front and rear sides of the top right side of the right hollow plate 100. 130, the bottom of the inner wall of the mounting groove 130 is fixedly connected to the limiting plate 320 by bolts. The right side wall of the limiting plate 320 extends to the outside of the mounting groove 130, and the bottom of the limiting plate 320 contacts the top of the hexagonal nut 312. This bridge cylindrical casting steel formwork reinforcement device can easily and quickly fix the hollow plates 100 on both sides to the outside of the formwork to reinforce and support the formwork through the fixing component 300. It is not only easy to operate, but also very convenient to install and disassemble. At the same time, the limiting plate 320 limits the hexagonal nut 312 to prevent loosening during use, improve the fixing effect and make the overall reinforcement more stable.

[0033] In use, the following steps are taken: After unscrewing the bolts on the fixing plate 220, remove the fixing plate 220 to release the limiting effect on the positioning rod 213. Then, slide the support block 212. The support block 212, through the connecting block 211, drives the limiting block 210 to slide in the slide groove 110. As the limiting block 210 slides, it simultaneously moves the positioning rod 213. Adjust the support blocks 212 on both sides to the corresponding positions according to the required size of the cylindrical template to be reinforced. Then, fit the corresponding insertion holes 221 on the fixing plate 220 onto the positioning rod 213 and fix the fixing plate 220 with bolts, thereby limiting and fixing the adjusted support blocks 212. Place the two hollow plates 100 on both sides of the template, so that the support blocks 212 on both sides contact the template surface. Then, rotate... The moving block 310, in conjunction with the first fixing port 120, rotates the fixing screw 311, moving the fixing screw 311 into the second fixing port 121. The hexagonal nut 312 is then rotated using a tool. When the hexagonal nut 312 contacts the right hollow plate 100, it presses against the right hollow plate 100. As the hexagonal nut 312 rotates, it, along with the fixing screw 311 and the rotating block 310, pulls the hollow plates 100 on both sides inwards, thus fixing them. This allows the hollow plates 100 on both sides, together with the support block 212, to reinforce and support the template. After installation, the limiting plate 320 is fixed in the mounting groove 130 using bolts. The limiting plate 320 limits the hexagonal nut 312, preventing loosening during use.
