Description

Technical Field

[0001] This utility model relates to the field of steel formwork technology, specifically a flattening mechanism for road and bridge steel formwork. Background Technology

[0002] Steel formwork for bridges and roads is a common formwork material used in the construction of bridges, roads, and other engineering projects. It is typically used during concrete pouring to help maintain the shape of the concrete and improve construction efficiency. Steel formwork is made of steel plates and other steel materials and is used to shape concrete structures. Steel formwork needs to be flattened. In bridge and road projects, uneven formwork surfaces can cause wavy or uneven surfaces on concrete components, thus affecting the quality of the project. The purpose of flattening steel formwork is to ensure that it does not deform during use, thereby achieving a flat, sealed, and stable effect, guaranteeing the accuracy and quality of the concrete structure, extending the service life of the formwork, and avoiding additional repair and maintenance work. A flattening mechanism for road and bridge steel formwork, disclosed in CN210816803U, includes a pull ring, a collar, a positioning ring, a positioning plate, a rotating shaft, a roller, a support frame, a positioning rod, a clamping plate, a connecting shaft, a baffle, a guide groove, a sliding tube, a handle, a hydraulic cylinder, a top plate, a secondary wheel, a wheel frame, a sleeve, a first helical spring, a sliding frame, a connecting plate, a guide rod, a second helical spring, a positioning plate, a pull rope, and a motor. This flattening mechanism can be used directly near the steel formwork, avoiding the need for transportation of the steel formwork. It also facilitates local repairs by flattening specific areas of the steel formwork. Furthermore, its design is reasonable, its operation is convenient, and it meets societal needs.

[0003] The aforementioned patent proposes that by setting up a hydraulic cylinder, and then combining it with rollers, local compression of the steel template can be achieved, which facilitates local trimming and flattening of the steel template. However, in actual use, as the steel template moves, the area that the top plate can flatten on the steel template is limited. As a result, when the top plate flattens the steel template at the next location, it does not hold the flattened steel template, and the template will deform in local areas, affecting the overall flatness of the template. Utility Model Content

[0004] The purpose of this utility model is to provide a flattening mechanism for road and bridge steel formwork, so as to solve the problem mentioned in the background art of not maintaining the flattened steel formwork.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flattening mechanism for road and bridge steel formwork, comprising a flattening structure, wherein the flattening structure includes an operating table and a motor installed inside the operating table, and an installation component is installed on the top of the operating table; The mounting components include two sets of fixing plates. The top of the fixing plates has a top groove. Rollers A are movably installed between the fixing plates. Inner support shafts are installed between the fixing plates and are located on both sides of the fixing plates. A pressing component is installed inside the top groove, and an adjusting component is installed at the top of the pressing component.

[0006] Preferably, the pressing component includes a movable plate, and two sets of movable plates are provided, with a roller B movably installed between the two sets of movable plates.

[0007] Preferably, a central strip is installed between the top ends of the movable plates, and an inverted T-shaped groove is opened at the center of the top end of the central strip. Limiting grooves are opened on both sides of the two sets of movable plates.

[0015] 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.

[0016] Example 1: Please refer to Figures 1-4 A flattening mechanism for road and bridge steel formwork includes a flattening structure 1, which includes an operating table 11 and a motor 12 installed inside the operating table 11. An installation component 13 is installed on the top of the operating table 11.

[0017] The mounting component 13 includes a fixing plate 131, which has two sets. The top of the fixing plate 131 has a top groove 134. A roller A133 is movably installed between the fixing plates 131. An inner support shaft 132 is installed between the fixing plates 131, and the inner support shaft 132 is located on both sides of the fixing plate 131. A pressing component 14 is installed inside the top groove 134, and an adjusting component 15 is installed at the top of the pressing component 14.

[0018] The pressing component 14 includes a movable plate 141, which is provided in two sets. A roller B143 is movably installed between the two sets of movable plates 141. The rollers B143 and A133 flatten the steel template. The staggered arrangement of rollers A133 and B143 can make the steel template be subjected to uniform and multi-directional pressure when passing through the device, reducing the risk of excessive pressure in local areas, reducing material fatigue damage, effectively smoothing out small pits, bumps or ripples on the surface, and further improving the surface flatness of the steel template.

[0019] A central strip 144 is installed between the top ends of the movable plates 141. An inverted T-shaped rotating groove 145 is opened in the middle of the top end of the central strip 144. Limiting grooves 142 are opened on both sides of the two sets of movable plates 141. The central strip 144 facilitates the control of the two sets of movable plates 141 and roller B143 to move together. The length of the movable plate 141 is consistent with the length of the top groove 134, so that the movable plate 141 is inside the top groove 134.

[0020] Limiting strips 135 are installed on both sides of the interior of the top groove 134. Threaded holes 136 are provided on the top of the fixing plate 131 and on both sides of the top groove 134. The threaded holes 136 facilitate fixing the pressing member 14 inside the top groove 134. The limiting strips 135 are adapted to the limiting groove 142 to limit the movement of the moving plate 141.

[0021] The top of the movable plate 141 is provided with an installation strip 146. Bolts 147 are installed on both sides of the top of the installation strip 146. A washer 148 is installed between the top of the installation strip 146 and the upper end of the bolts 147. The length of the installation strip 146 is greater than the length of 134, so that the installation strip 146 can be fixed to the top of the fixed plate 131 by using bolts 147.

[0022] In this embodiment: the steel template is placed at the top of roller A133, and roller B143 is at the top of the steel template. The steel template is pushed to one side of the device. There are multiple sets of rollers A133 and roller B143. After one set of rollers A133 and roller B143 flattens the steel template, as the steel template is pushed, one end of the steel template moves into the next set of rollers A133 and roller B143. Rollers A133 and roller B143 hold the steel template immediately after flattening, which can reduce the need for operators to move or adjust the steel template and maintain its flatness. Setting multiple sets of rollers A133 and roller B143 can prevent the steel template from deforming again, thereby ensuring the smooth progress of subsequent work.

[0023] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-4 The adjusting component 15 includes a top bar 151 and a threaded shaft 153 threaded through the middle of the top bar 151. A rotating handle 152 is installed at the top of the threaded shaft 153, and an inner rotating block 154 is installed at the bottom of the threaded shaft 153. The inner rotating block 154 is movably installed inside the inverted T-shaped rotating groove 145 to facilitate control of the position of the middle bar 144. After the mounting strip 146 and bolt 147 fix the position of the lowering component 14, the adjusting component 15 adjusts the position of the moving plate 141, the roller B143 and the middle bar 144.

[0024] In this embodiment: the mounting strip 146 is installed on the top of the fixed plate 131, and the bolt 147 is used to fix the mounting strip 146 and the fixed plate 131. Before flattening steel templates of different sizes, the rotating handle 152 can be held and rotated to drive the threaded shaft 153 and the inner rotating block 154 to rotate. The inner rotating block 154 is located inside the inverted T-shaped rotating groove 145. As the rotating handle 152 rotates, it will push the central strip 144 to move down, that is, drive the moving plate 141 to move down at the middle of the fixed plate 131 with the top groove 134. Since the moving plate 141 has limit grooves 142 at both ends, which are used in conjunction with the limit strip 135 to limit the angle of the moving plate 141. When the moving plate 141 moves down, the roller B143 will approach the top of the steel template, which makes it easier for the device to flatten steel templates of different thicknesses.
