Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to an adjustable bearing pad template. Background Technology

[0002] Currently, wooden formwork is commonly used for concrete padding at construction sites. However, wooden formwork is less durable than steel formwork, and it often deforms after only two spans of padding are poured. Furthermore, because the formwork height is fixed, workers need to mark lines on the inside of the formwork to determine the pouring height, which is inconvenient. Inaccurate control of the elevation during finishing also leads to deviations in the padding elevation. Problematic padding needs to be addressed during subsequent beam and slab erection, significantly reducing construction efficiency.

[0003] Therefore, it is necessary to propose an adjustable bearing pad stone template to solve the above problems. Utility Model Content

[0004] Technical Problem to be Solved: The purpose of this utility model is to provide an adjustable bearing pad stone formwork to solve the problems mentioned in the background art, which are that the existing bearing pad stone formwork is usually made of wood. Wood formwork is not as durable as steel formwork. It deforms after pouring two spans of bearing pad stone. In addition, since the height of the formwork is fixed, the workers need to use chalk lines on the inside of the formwork to determine the pouring height, which is not simple to construct. The elevation control is not accurate when finishing, which leads to deviations in the elevation of the pad stone. The problematic pad stone needs to be treated when erecting beams and slabs, which greatly reduces the construction efficiency.

[0005] Technical Solution: To achieve the above objectives, this utility model is implemented through the following technical solution: An adjustable support pad template includes an inner frame and an outer frame that are movably fitted together. Both the inner and outer frames are rectangular. Two base supports are fixedly installed on each of the four outer side walls of the inner frame, and the base supports on each side wall of the inner frame are symmetrically arranged on both sides of its bottom. A screw is fixedly installed vertically on the top of the base support, and a washer is movably fitted on the screw. The washer is fixedly connected to the bottom of the outer frame, and nuts I and II are threaded onto the screw on the upper and lower sides of each washer, respectively.

[0006] Preferably, the four outer side walls of the inner frame are provided with vertical scale lines.

[0007] Preferably, the tops of the two screws located at the same vertical angle of the inner frame are fixedly mounted with the same L-shaped plate.

[0008] Preferably, both the inner frame and the outer frame are welded from steel plates with a thickness of 3mm.

[0009] Beneficial Effects: Compared with the prior art, this utility model provides an adjustable bearing pad template. This adjustable bearing pad template has a unique structure and is easy to use. In the initial state, the top surfaces of the inner frame and the outer frame are flush. When the pad pouring operation is required, the worker first moves the nuts I on each screw upward to create enough space for the outer frame to rise. Then, the outer frame is pushed upward until the distance between its top surface and the bottom surface of the inner frame reaches the required pouring height. When the outer frame reaches the predetermined position, the nuts II on each screw are rotated upward to make them closely contact the bottom surface of the pad, providing initial support for the outer frame. Subsequently, each nut I is moved downward to make its bottom surface contact the top surface of the pad. In this way, through the dual action of nuts I and II, the outer frame is firmly fixed at the required height position, thereby ensuring the stability of the pad pouring process.

[0010] Compared to traditional wooden formwork, this formwork is welded from 3mm thick steel plates, which greatly improves its durability and allows it to maintain its shape and performance during multiple foundation stone pouring processes. In addition, through the use of components such as screws, nuts I, nuts II, and washers, workers can flexibly adjust the height of the outer frame according to actual construction needs. This height adjustment mechanism is not only easy to operate, but also allows for precise control of the foundation stone elevation during construction, effectively avoiding elevation deviation problems caused by fixed formwork height.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Example 1: This Example 1 provides an adjustable bearing pad stone formwork, which is a direct improvement on the existing bearing pad stone formwork. It features a unique structure. Please refer to [link / reference]. Figure 1-3As shown, the device includes an inner frame 1 and an outer frame 2 that are movably fitted together. Both the inner frame 1 and the outer frame 2 are welded from steel plates with a thickness of 3mm. Both the inner frame 1 and the outer frame 2 are rectangular. Two base supports 3 are fixedly installed on each of the four outer side walls of the inner frame 1, and the base supports 3 on each side wall of the inner frame 1 are symmetrically arranged on both sides of its bottom. A screw rod 4 is fixedly installed vertically on the top of the base support 3. A washer 5 is movably fitted on the screw rod 4. The washer 5 is fixedly connected to the bottom of the outer frame 2, and nuts I 6 and II 7 are threaded onto the screw rod 4 on the upper and lower sides of each washer 5, respectively. There are various ways to connect the inner frame 1 and the base support 3, as well as the outer frame 2 and the washer 5. For example, the inner frame 1 and the base support 3, and the outer frame 2 and the washer 5 are all fixed together by welding.

[0017] Working principle: In the initial state, the top surfaces of the inner frame 1 and the outer frame 2 are flush. When using this template to pour the foundation stone, the worker first adjusts the height of the template according to the requirements. During adjustment, the nut I6 on each screw 4 is moved upward, and then the outer frame 2 is pushed upward until the distance between the top surface of the outer frame 2 and the bottom surface of the inner frame 1 reaches the required height. At this time, the nut II7 on each screw 4 is rotated upward until the nut II7 contacts the bottom surface of the washer 5. Then, the nut I6 is moved downward so that the bottom surface of the nut I6 contacts the washer 5, thereby fixing the outer frame 2. Then the pouring operation can be carried out.

[0018] Example 2: The difference between Example 2 and Example 1 is as follows: Figure 2 As shown, the four outer side walls of the inner frame 1 are provided with vertical scale lines 9. In the initial state, the bottom surface of the outer frame 2 is flush with the 0 mark of the scale line 9. When adjusting the height of the template, it is only necessary to observe the scale line 9 on the inner frame 1, without the need to use external measuring tools. The top of the two screws 4 located at the same vertical angle of the inner frame 1 is fixedly installed with the same L-shaped plate 8. By using the L-shaped plate 8 to fix the two adjacent screws 4 together, not only is the stability of the screws 4 enhanced, but the upper end of the screws 4 can also be prevented from scratching the workers.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
