[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] To address the problem that existing steel templates have fixed and non-adjustable dimensions, requiring multiple custom-made steel templates of corresponding sizes to manufacture bridge bearing pad stones of different sizes, resulting in poor compatibility and high costs, this invention provides an adjustable steel template device for bridge bearing pad stones. This device enables the manufacture of bridge bearing pad stones of various sizes using a single steel template, offering strong compatibility and low cost.

[0026] It should be noted that the adjustable steel formwork device described in this utility model is used for, but not limited to, bridge bearing pad stones. For ease of explanation, this utility model only uses the application of the adjustable steel formwork device to bridge bearing pad stones as an example. The principle of the adjustable steel formwork device applied to other types of equipment is essentially the same as that applied to bridge bearing pad stones, and will not be elaborated here.

[0027] Please see Figure 1 , Figure 1 This is a schematic diagram of the adjustable steel formwork device according to an embodiment of the present invention. The adjustable steel formwork device includes a formwork assembly 1 and a connecting assembly 2. The formwork assembly 1 includes a first angle steel member 11, a second angle steel member 12, and an adjusting member 13. Both the first angle steel member 11 and the second angle steel member 12 have slots 111 for engaging the corners of the bridge bearing pad stones. The two sides of the adjusting member 13 abut against the first angle steel member 11 and the second angle steel member 12, respectively. The connecting assembly 2 detachably connects the first angle steel member 11, the second angle steel member 12, and the adjusting member 13, and can fix the first angle steel member 11 and the second angle steel member 12 at different intervals.

[0028] In this embodiment, the adjusting member 13 is plate-shaped. It works in conjunction with the inner walls of the first angle steel member 11 and the second angle steel member 12 to press against the concrete, thus fixing and positioning the concrete to form the shape of the bridge bearing pad. The adjusting member 13 of appropriate size can be selected according to the required size of the bridge bearing pad, ensuring that the adjusting member 13, the first angle steel member 11, and the second angle steel member 12 fit together perfectly to compress the concrete. The connecting assembly 2 is used to detachably connect the first angle steel member 11, the second angle steel member 12, and the adjusting member 13. When the adjusting member 13 needs to be replaced, the connecting assembly 2 can be disassembled first, the adjusting member 13 replaced, and the connecting assembly 2 reinstalled. This allows the adjustable steel formwork device to be compatible with fixing various sizes of bridge bearing pads, providing strong compatibility and eliminating the need for custom-made steel formwork for each size of bridge bearing pad, thus reducing costs.

[0029] The connecting component 2 is mainly used to detachably connect the first angle steel member 11, the second angle steel member 12 and the adjusting member 13, so that the first angle steel member 11, the second angle steel member 12 and the adjusting member 13 can be connected together or disassembled and separated, so as to facilitate the replacement of the adjusting member 13, so that the adjusting member 13 and the inner surface formed by the first angle steel member 11 and the second angle steel member 12 can cooperate to press the concrete.

[0030] In one embodiment, please refer to Figure 1The connecting component 2 includes a connecting rod 21 and multiple binding members 22. The first angle steel member 11, the second angle steel member 12, and the adjusting member 13 all have through holes (not shown in the figure). The binding members 22 are fitted onto the connecting rod 21, with both ends of the binding members 22 passing through the corresponding through holes, and then the two ends of the binding members 22 are knotted. In this embodiment, the binding members 22 can be steel wire or thin rope. The binding members 22 can first be fitted onto the connecting rod 21, and then pass through the corresponding through holes. The first angle steel member 11, the second angle steel member 12, and the adjusting member 13 have two through holes. The two ends of the binding members 22 pass through the two through holes and are knotted on the other side, thus locking and fixing the first angle steel member 11, the second angle steel member 12, and the adjusting member 13 to the connecting rod 21. Therefore, the first angle steel member 11, the second angle steel member 12, and the adjusting member 13 are connected and fixed through the connecting rod 21. When it is necessary to disassemble the adjusting component 13, the binding 22 can be untied first, the connecting rod 21 can be disassembled, and then the adjusting component 13 can be disassembled.

[0031] In another embodiment, please refer to Figure 4 The connecting assembly 2 includes a connected screw 23 and a handle 24. The first angle steel member 11, the second angle steel member 12, and the adjusting member 13 are all provided with lugs 25, each lug 25 having a through screw hole. Multiple screw holes are arranged coaxially, and the screw 23 is threaded through multiple screw holes. In this embodiment, the first angle steel member 11, the second angle steel member 12, and the adjusting member 13 are connected together by the screw 23. When it is necessary to disassemble the adjusting member 13, the screw 23 can be threaded out of each lug 25 in sequence, making disassembly and assembly quick and convenient.

[0032] In one embodiment, please refer to Figure 2 The first angle steel member 11 includes a base 112, a lifting plate 113, and a locking member 114. The lifting plate 113 is slidably connected to the base 112, and the locking member 114 connects the base 112 and the lifting plate 113, and can fix the lifting plate 113 in its current position when it is in the locked state. In this embodiment, the inner area of ​​the first angle steel member 11 can be adjusted by sliding the lifting plate 113 up and down relative to the base 112. When the lifting plate 113 slides upward relative to the base 112, the inner area of ​​the first angle steel member 11 gradually increases; when the lifting plate 113 slides downward relative to the base 112, the inner area of ​​the first angle steel member 11 gradually decreases, so that the first angle steel member 11 can adapt to the limiting and fixing of bridge bearing pad stones of different areas. The locking member 114 can lock or unlock the lifting plate 113. When unlocked, the lifting plate 113 can slide up and down relative to the base 112. When the lifting plate 113 slides to the target position, the locking member 114 can lock the lifting plate 113 so that the lifting plate 113 remains fixed in the current position.

[0033] In one embodiment, please refer to Figure 2The locking component 114 includes a stud 115 and a first screw 116. One end of the stud 115 is fixed to the base 112, and the other end of the stud 115 passes through the lifting plate 113. The first screw 116 is threaded onto the stud 115 and abuts against the lifting plate 113. In this embodiment, the first screw 116 can move up and down relative to the stud 115 through its threads when rotating. When the first screw 116 moves upward, it can drive the lifting plate 113 to rise, and when it moves downward, the lifting plate 113 can descend by its own gravity.

[0034] Further, please refer to Figure 3 The locking component 114 also includes a second screw 117. The lifting plate 113 has a first flange 118, a stud 115 passes through the first flange 118, a first screw 116 abuts against the side of the first flange 118 facing the base 112, and the second screw 117 is threaded onto the stud 115 and abuts against the side of the first flange 118 facing away from the first screw 116. Compared to the previous embodiment, this embodiment adds a second screw 117. When adjusting the height of the lifting plate 113, the first screw 116 and the second screw 117 can be rotated simultaneously to drive the lifting plate 113 to rise and fall by pressing against the first flange 118. The second screw 117 can limit the top of the lifting plate 113 to completely lock the lifting plate 113.

[0035] In one embodiment, please refer to Figure 3 The locking component 114 also includes a third screw 119. The base 112 is a U-shaped steel with a second flange 120. A stud 115 passes through the second flange 120. The third screw 119 is threaded onto the stud 115 and abuts against the side of the second flange 120 facing the first flange 118. In this embodiment, the third screw 119 is welded to the second flange 120, and the stud 115 is threaded through the third screw 119 and welded to the second flange 120. The third screw 119 is used to increase the fixing area of ​​the stud 115, so that the stud 115 can remain fixed for a long time. The first screw 116 and the second screw 117 can drive the lifting plate 113 to rise and fall stably when rotated.

[0036] In one embodiment, please refer to Figure 5 The adjustable steel formwork device also includes a third angle steel member 14, with an installation space formed between the third angle steel member 14 and the second angle steel member 12. The installation space is provided with another adjusting member 13. The second angle steel member 12, the third angle steel member 14 and the adjusting member 13 can be detachably connected by another connecting component 2, so that the inner surface formed by the connection of the second angle steel member 12, the third angle steel member 14 and the adjusting member 13 can limit and fix the bridge bearing pad stone.

[0037] In one embodiment, please refer to Figure 5The adjustable steel formwork device also includes a fourth angle steel member 15. Installation spaces are formed between the fourth angle steel member 15, the third angle steel member 14, and the first angle steel member 11. Adjustment members 13 are respectively provided in both installation spaces.

In this embodiment, there are four adjustment members 13, arranged around the perimeter of the adjustable steel formwork device. Each adjustment member 13 has corresponding angle steel members connected to both sides. The four adjustment members 13 and the four angle steel members enclose a closed steel formwork, which can be used to limit and fix rectangular bridge bearing pad stones. When it is necessary to replace an adjustment member 13, it is usually necessary to replace two opposing adjustment members 13 simultaneously so that the steel formwork can still maintain its rectangular shape after installing a new adjustment member 13.

[0038] In one embodiment, slots (not shown in the figure) are provided on the sides of the first angle steel member 11 and the second angle steel member 12 that are close to each other, and the two sides of the adjusting member 13 are slidably inserted into the two slots. In this embodiment, the adjusting member 13 can be slidably engaged with the first angle steel member 11 and the second angle steel member 12 for pre-fixation, and then the connecting assembly 2 is used to connect the adjusting member 13, the first angle steel member 11 and the second angle steel member 12 in sequence to complete the connection and fixation.

[0039] To better understand this utility model, the following is combined with... Figures 1 to 5 The technical solution of this utility model is described in detail below:

[0040] The adjustable steel formwork device provided by this utility model has a first angle steel member 11 and a second angle steel member 12, both of which have slots 111, allowing them to be engaged with the corners of bridge bearing pad stones via the slots 111.
