Description
Technical Field
[0001] This utility model belongs to the technical field of sound barrier foundation embedded parts installation, specifically relating to a limiting device for bridge sound barrier foundation embedded parts. Background Technology
[0002] Sound barriers play a vital role in modern transportation and industry, and are widely used in various transportation and municipal road sections such as highways, railways, light rail, and viaducts. They effectively block the propagation path of vehicle noise, significantly reduce the interference of traffic noise on surrounding residents, and strongly protect the environmental quality of residents during production, living, and working processes. In industrial production areas, sound barriers also play an indispensable role. They can effectively block transmitted sound and significantly attenuate the noise generated by industrial equipment, not only building a solid defense for the hearing health of workers, but also significantly improving the overall environmental quality around factories.
[0003] With the increasing emphasis on and in-depth implementation of green and environmentally friendly concepts throughout society, the application market for sound barriers, as a direct and efficient noise reduction device, is showing a continuous expansion trend. Currently, the steel structure columns and sound-absorbing and sound-insulating panels of sound barriers are usually processed and manufactured in factories. Under the standardized production environment of factories, the structural dimensions and processing precision of these components can be well controlled. However, in actual construction sites, the steel structure columns of the sound barrier need to be installed on the foundation embedded parts, which places extremely high demands on the installation and positioning precision of the sound barrier embedded parts.
[0004] Specifically, during on-site construction, the error requirements for embedded parts in terms of horizontal, vertical, and perpendicularity must be accurate to the millimeter level. Moreover, the more embedded parts there are, the more difficult it is to accurately control the embedded error. Currently, the most common method on construction sites is to use steel reinforcement supports to fix the embedded parts one by one and then correct them. However, this method has obvious drawbacks: if the construction speed is too fast, the installation accuracy of the embedded parts cannot be guaranteed, and the acceptance standards cannot be met; on the other hand, if the construction accuracy is to be ensured, the construction progress will inevitably be delayed. In addition, steel reinforcement supports are disposable tools and cannot be recycled, which undoubtedly greatly increases the construction cost.
[0005] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content
[0006] The purpose of this utility model is to provide a limiting device for the foundation embedded parts of a bridge sound barrier, so as to solve the technical problems of inconvenience in uniformly limiting the embedded parts during the construction of the foundation, low construction efficiency and high construction cost.
[0007] To achieve the above objectives, the bridge sound barrier foundation embedded part limiting device of this utility model provides the following technical solution:
[0008] A limiting device for embedded parts in the foundation of a bridge sound barrier includes:
[0009] A connecting crossbar, which is used to be detachably connected to the formwork of the bridge being poured;
[0010] A supporting vertical rod is provided, which is perpendicular to the connecting horizontal rod.
[0011] A fixing structure is provided on a supporting vertical rod;
[0012] A limiting steel plate has a set of positioning through holes. The number of positioning through holes is not less than the number of foundation embedded parts required for one column installation position. Each positioning through hole is used to pass through one foundation embedded part.
[0013] The fixed structure is provided with a locking component, and the limiting steel plate is detachably connected to the fixed structure through the locking component.
[0014] As a further optimized technical solution, the connecting crossbar is provided with a through hole, and a connecting bolt assembly is installed through the through hole.
[0015] As a further optimized technical solution, the fixing structure includes a horizontal extension rod, one end of which is fixedly connected to the supporting vertical rod.
[0016] As a further optimized technical solution, the locking component is arranged at the end of the horizontal extension rod away from the supporting vertical rod. The locking component includes a supporting horizontal groove with the opening facing away from the supporting vertical rod. The supporting horizontal groove is used to horizontally place a limiting steel plate, and a clamping element for pressing the limiting steel plate is provided on the supporting horizontal groove.
[0017] As a further optimized technical solution, the clamping element is a set bolt, which passes through the support transverse groove and is threaded into the support transverse groove.
[0018] As a further optimized technical solution, the set bolt is set on the top wall of the supporting transverse groove.
[0019] As a further optimized technical solution, the limiting steel plate is provided with vibration holes for vibrating and pouring concrete at the location of the foundation embedded parts.
[0020] As a further optimized technical solution, the feature is that a soft and elastic buffer pad is provided at the position of the limiting steel plate corresponding to the clamping part.
[0021] As a further optimized technical solution, the vibration hole is arranged in the middle of the limiting steel plate.
[0022] Beneficial effects:
[0023] (1) With the help of a set of positioning through holes on the limiting steel plate, a unified limiting operation can be carried out on a number of foundation embedded parts at a column installation position at one time. Compared with the traditional mode of fixing embedded parts one by one, this device solves the problem of error accumulation that is difficult to avoid due to individual operation from the root, so that the installation accuracy of embedded parts in terms of horizontal, vertical and vertical aspects is greatly improved, and the construction efficiency is high. It fully meets the strict construction acceptance standards and provides a solid and reliable foundation for the subsequent installation of sound barriers.
[0024] (2) The key components of the device, such as the connecting crossbar and the bridge template, the limiting steel plate and the fixed structure, are all designed to be detachable. This design allows construction personnel to flexibly and conveniently install, disassemble and adjust the position of the device according to the actual site conditions during the construction process, which greatly improves construction efficiency, shortens the construction cycle and reduces construction difficulty.
[0025] (3) Unlike traditional disposable steel reinforcement supports, the pre-embedded limit device for the foundation of the bridge sound barrier has excellent reusability. After completing a construction task, it can be put into use in subsequent construction projects through simple disassembly, cleaning and maintenance. After multiple engineering practices, it has been verified that long-term use of this device can significantly reduce the procurement cost of construction materials, avoid the waste of a large amount of disposable materials, and save considerable expenses for the project.

[0030] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art are within the protection scope of this utility model.
[0031] In the description of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. The terms "connected" and "linked" used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.
[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0033] The shapes and sizes of the components in the attached drawings do not reflect the actual proportions of the product; they are only intended to illustrate the content of this utility model.
[0034] This utility model provides a limiting device for foundation embedded parts of a bridge sound barrier. An installation position is reserved at the top of the steel formwork of the box girder flange. A connecting crossbar is detachably installed on the steel formwork. A supporting vertical bar is fixedly installed on the connecting crossbar. A fixing structure is fixedly installed on the supporting vertical bar. By installing a limiting steel plate on the fixing structure, a set of foundation embedded parts is limited at one time using the limiting steel plate. The construction is convenient and efficient, which helps to ensure construction accuracy and can be standardized. This device can be reused repeatedly, saving costs.
[0035] Specifically, a 32m cast-in-place box girder for a single railway span is used as an example for detailed explanation. The sound barrier for this 32m cast-in-place box girder consists of 32 sets of embedded parts, with each set containing 12 foundation embedded parts. According to the "Standard for Acceptance of Construction Quality of Railway Sound Barrier Engineering" TB10428-2012, the verticality error of the bolts should not exceed 0.2%, the allowable deviation in the length of the exposed foundation embedded parts is ±3mm, and the horizontal and vertical positional deviation of the bolts should not exceed 2mm. Using existing steel reinforcement supports to fix and correct each bolt individually has several drawbacks. Fixing too quickly results in insufficient accuracy, failing to meet acceptance requirements; while correcting each bolt individually ensures high accuracy, delaying construction progress. Furthermore, using disposable steel for fixing prevents recycling, leading to high labor and material costs.
[0036] The bridge sound barrier foundation embedded part limiting device of this utility model includes a connecting horizontal bar 1, a supporting vertical bar 2, a fixing structure 3 and a limiting steel plate 4.
[0037] like Figure 1-2 As shown, the connecting crossbar 1 is made of angle steel. Two through holes are provided on the connecting crossbar 1, and connecting bolt assembly 7 is installed through the through holes. The device is detachably connected to the steel formwork for bridge casting by using the connecting bolt assembly 7.
[0038] There are two parallel support vertical rods 2, both of which are made of angle steel. The support vertical rods 2 are set perpendicular to the connecting horizontal rod 1, and their height is close to the foundation embedded parts that need to be limited.
[0039] The fixing structure 3 is set on the supporting vertical rod 2, specifically including a horizontal extension rod made of angle steel. One end of the horizontal extension rod is fixedly connected to the supporting vertical rod 2, and a locking component 5 is provided at the end of the horizontal extension rod away from the supporting vertical rod 2.
[0040] The limiting steel plate 4 has a set of positioning through holes 6, the number of which is no less than the number of foundation embedded parts required for one column installation position. In this embodiment, the set of positioning holes has 12 holes, and each positioning through hole 6 is used to pass through one foundation embedded part. The limiting steel plate 4 is detachably connected to the fixing structure 3 by locking component 5.
[0041] Specifically, the locking component 5 includes a support transverse groove, which is made of three sections of angle steel. One of the longer sections of angle steel is fixedly connected to the horizontal extension rod, and the two shorter sections of angle steel are set on the upper part of the longer section of angle steel and form a support transverse groove for placing the limiting plate 4 with the bottom section of angle steel. The opening of the support transverse groove is set away from the support vertical rod 2, so as to facilitate the horizontal placement of the limiting steel plate 4. A clamping member 8 for pressing the limiting steel plate 4 is provided on the support transverse groove.
[0042] In this embodiment, the clamping member 8 is a set bolt, which passes through the support transverse groove and is threaded into it. Thus, after the limiting steel plate 4 is placed in the support transverse groove, the limiting steel plate 4 can be fixed in the support transverse groove by tightening the set bolt towards the limiting steel plate 4, and the limiting steel plate 4 can be disassembled by tightening the set bolt away from the limiting steel plate 4.
[0043] To facilitate operation of the set screws, they are positioned on the top wall of the supporting transverse groove. This ensures that when installing the limiting steel plate 4, the set screws face directly towards the operator, making it easier for them to tighten them.
[0044] Furthermore, the limiting steel plate 4 is equipped with vibration holes 9 for vibrating the concrete at the location of the foundation embedded parts during pouring. The rational layout of the vibration holes 9 in the middle of the limiting steel plate 4 plays a crucial role in the concrete pouring process. Construction workers can use the vibration holes 9 to insert the vibrating equipment deep into the concrete around the foundation embedded parts, ensuring that the concrete evenly and fully fills every gap, forming a tight and stable bond between the foundation embedded parts and the concrete. This optimized vibration method greatly improves the stability of the entire sound barrier foundation, effectively extends the service life of the sound barrier, and reduces subsequent maintenance costs.
[0045] Furthermore, a soft and elastic buffer pad 10 is provided at the position of the limiting steel plate 4 corresponding to the clamping member 8. When the clamping member 8 clamps the limiting steel plate 4, the buffer pad 10 acts as a sturdy protective barrier, effectively absorbing and dispersing the pressure and friction generated during the clamping process, preventing the clamping member 8 from causing scratches, wear, or other damage to the limiting steel plate 4. This not only significantly extends the service life of the limiting steel plate 4 but also greatly improves the durability of the entire device, reducing replacement costs and time losses due to component damage.
[0046] It is understood that the above description is merely exemplary and the embodiments of this application do not limit the scope of the application.
[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
