Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to an integrated hoisting and bracket combined support device. Background Technology

[0002] Due to the high piers, continuous rigid frame bridges often employ off-the-ground scaffolding for their beam segments during construction. This method is well-suited for high-pier bridge construction, reducing the amount of scaffolding material used and thus lowering costs. However, a drawback of existing technology is that during later dismantling, the scaffolding, located at the bottom of the beam segment, cannot be vertically lifted for removal. Typically, the scaffolding components must be dragged out one by one from below the beam segment. This dismantling method is inefficient and poses significant safety risks during high-altitude operations, and existing methods cannot effectively address these issues.

[0003] Chinese patent CN 212771960 U discloses a bracket removal device for block 0, which can remove the bracket as a whole, but it can only remove the bracket for block 0 and is not universally applicable to the construction of other beam segments. Chinese utility model patent CN 113818362 A introduces an integrated structure and construction method for prefabricated brackets and hanging baskets, describing the steps of the construction method, including pier pre-construction, block 0 construction, hanging basket module construction, and hanging basket pre-stressing construction, but it uses a complex bracket system and does not consider the construction steps during removal. Chinese patent CN208293447U discloses a device for the overall removal of cap beam brackets, which is easy to operate, not limited by site, and can efficiently and quickly complete the removal operation, but it is only applicable to the overall removal of cap beams and cannot be applied to continuous rigid frame bridges.

[0004] These limitations make existing technologies difficult to apply effectively in practice, hindering the resolution of challenges in dismantling non-grounded scaffolding systems for high-pier bridges. Therefore, to improve the efficiency and safety of the scaffolding dismantling process, reduce the impact on construction progress and the threat to construction workers' safety, a new technology combining lifting and bracket dismantling, applicable to all beam segments, needs to be developed. Utility Model Content

[0005] To address the shortcomings in the aforementioned background technology, this utility model proposes an integrated hanging and bracket combined support device, which solves the problem of low dismantling efficiency of non-grounded supports in the prior art.

[0006] The technical solution of this utility model is implemented as follows: an integrated suspension and bracket combined support device includes a support bracket set on a bridge pier, the support bracket being detachably connected to the bridge pier via an anchoring rod; a bracket module is set on the support bracket, a support module is set above the bracket module, a suspension module is connected to the support module, and the suspension module is connected to the upper end of the bridge pier or a beam segment set above the bridge pier. The support bracket, as a key component connecting the bridge pier and the bracket module, provides convenience for subsequent dismantling operations through its detachable connection method.

[0007] Preferably, the bracket module includes several tripods mounted on supporting brackets, with the upper ends of the tripods collectively supporting the bracket module. Specifically, the tripods include several pairs of hinged horizontal and diagonal bars, with adjacent diagonal and / or horizontal bars connected by transverse connecting rods. The core component of the bracket module, the tripod, uses horizontal and diagonal bars hinged together and connected by transverse connecting rods to form a stable structure. This design ensures the load-bearing capacity of the bracket module while allowing for flexible adjustments according to actual needs.

[0008] Preferably, the supporting brackets are provided in two layers, with the two layers of supporting brackets cooperating with one end of the horizontal bar and the lower end of the diagonal bar, respectively, to ensure stable support for the bracket module.

[0009] Preferably, the support module includes a bottom formwork, the bottom of which is connected to a horizontal bar, and several trusses are fixedly installed on the bottom formwork. The bottom formwork is a steel formwork and is fixedly connected to the horizontal bar by bolts. Lifting lugs are fixedly installed on the trusses and are connected to the hanger module. The combined structure of the bottom formwork and the trusses not only provides a reliable support platform for bridge construction, but also, through the connection of the lifting lugs and the hanger, enables the overall lowering during dismantling.

[0010] Preferably, the lifting module includes several pairs of pulley blocks and winches fixedly installed on the top surface of the beam segment or the top of the pier. The lifting ropes of the winches pass over the pulley blocks and are connected to the lifting lugs on the truss. By utilizing the cooperation of the pulley blocks and the winches, the bracket module and the support module can be lifted smoothly, the lowering speed can be effectively controlled, and the safety of the dismantling process can be ensured.

[0011] Preferably, the supporting bracket is a steel bracket, and the supporting bracket is provided with through holes to allow the anchoring tie rod to pass through; the lower end of the hoisting rope of the winch is connected to a lifting rod, which is connected to the lifting lug. By setting the lifting rod, the stability of the hoisting is further improved.

[0012] The beneficial effects of this utility model are: 1. Improved construction efficiency: By welding the bracket module and support module into a single unit, dismantling can be achieved in one go, avoiding the tedious process of dismantling the bracket and support modules multiple times in traditional methods, greatly saving time and labor. At the same time, eliminating the dismantling step and using a whole-unit hoisting method improves the stability of the hoisting process.

[0013] 2. Simple Operation: The demolition method described in this utility model simplifies the demolition steps, making the operation simpler and faster. It only requires cutting the anchoring rods at the connection between the supporting bracket and the pier, and then using a hoisting module to lower the entire structure to the ground, reducing the complexity and risks of high-altitude operations.

[0014] 3. Improved safety: By reducing the number and complexity of high-altitude operations, the risks to construction workers working at heights are reduced, thereby improving construction safety. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] like Figure 1 , 2As shown in Embodiment 1, an integrated suspension and bracket combined support device includes a support bracket 8 mounted on a bridge pier. The support bracket 8 is detachably connected to the bridge pier via an anchoring rod 9, facilitating its installation and disassembly. A bracket module 7 is mounted on the support bracket 8, and a support module 5 is mounted above the bracket module 7. A suspension module 4 is connected to the support module 5, and the suspension module 4 is connected to the upper end of the bridge pier or a beam segment mounted above the bridge pier. This allows the suspension module 4 to be installed and supported using the bridge pier or beam end. The support bracket 8, as a key component connecting the bridge pier and the bracket module, provides convenience for subsequent dismantling operations due to its detachable connection.

[0019] Example 2: An integrated hanging and bracket combined support device. Based on Example 1, the bracket module 7 includes several tripods 71 ​​mounted on supporting brackets 8, with the upper ends of the tripods 71 ​​collectively supporting the bracket module 5. In this example, the tripods 71 ​​include several pairs of hinged horizontal bars 711 and diagonal bars 712, with adjacent diagonal bars 712 and / or horizontal bars 711 connected by transverse connecting rods. The core component of the bracket module, the tripod, uses horizontal bars and diagonal bars hinged together and connected by transverse connecting rods to form a stable structure. This design ensures the load-bearing capacity of the bracket module while facilitating flexible adjustments according to actual needs.

[0020] Specifically, in this embodiment, the supporting bracket 8 is provided in two layers. The two layers of supporting bracket 8 respectively cooperate with one end of the horizontal bar 711 and the lower end of the diagonal bar 712, ensuring stable support for the bracket module. The supporting bracket 8 is a steel bracket, and the supporting bracket 8 is provided with through holes to allow the anchoring rod 9 to pass through. The steel bracket ensures both load-bearing capacity and convenient connection and disassembly.

[0021] Example 3: An integrated hanging and bracket combined support device, based on Example 2, wherein the support module 5 includes a bottom template 3, the bottom of which is connected to a horizontal bar 711, and several trusses 2 are fixedly installed on the bottom template 3.

[0022] Specifically, in this embodiment, the bottom formwork 3 is a large steel formwork, which is laid on the horizontal bar of the tripod and fixedly connected to the horizontal bar 711 by bolts. Lifting lugs are fixedly installed on the truss 2, and these lugs are connected to the hanger module 4. The combined structure of the bottom formwork and the truss not only provides a reliable support platform for bridge construction but also, through the connection of the lifting lugs and the hanger, allows for overall lowering during dismantling. The opening formed in the center of the bottom formwork meets the requirements for the installation of bridge piers.

[0023] Example 4 describes an integrated lifting and bracket combined support device. Based on Example 3, the lifting module 4 includes several pairs of pulley blocks 41 and winches fixedly installed on the top surface of the beam segment or the top of the pier. The hoisting ropes of the winches pass over the pulley blocks 41 and are connected to the lifting lugs on the truss 2. By utilizing the cooperation of the pulley blocks and the winches, the bracket module and the support module can be lifted smoothly, the lowering speed can be effectively controlled, and the safety of the dismantling process can be ensured.

[0024] Furthermore, a boom is connected to the lower end of the hoisting rope of the winch, and the boom is connected to the lifting lug. Example 5, a dismantling construction method using the integrated hoist and bracket combined support device as described in the above examples, includes the following steps: Step 1: Install the hanger module 4 on the upper end of the bridge pier or on the beam segment above the bridge pier, and connect the hanger module 4 to the support module 5. In this embodiment, the bracket module 7 and the support module 5 are connected as a whole by bolts, which can be dismantled in one go, avoiding the cumbersome process of dismantling the bracket module and support module in multiple stages in the traditional method, greatly saving time and labor. The overall hoisting and dismantling method improves the stability of construction.

[0025] Step 2: Connect the lifting lugs of the hanger module 4 and the support module 5 to integrate the entire dismantling device into one unit, so that the hanger module can be used to pull and support the support module and other components in the future.

[0026] Step 3: Cut the anchor rod 9 at the connection between the support bracket 8 and the pier. As an optional solution, the hoisting rope of the traction machine of the hanger module can be tensioned before cutting the anchor rod to facilitate the cutting of the anchor rod.

[0027] Step 4: Lower the bracket module 7 and support module 5 to the ground as a whole using the gantry module 4. This demolition method minimizes the time spent working at heights and the risks to personnel by lowering the entire structure.

[0028] This demolition method simplifies the demolition process, enabling the entire structure to be lowered without the need to disassemble and hoist each component separately, making the operation simpler and faster. It only requires cutting the anchoring rods at the connection between the supporting bracket and the pier, and then using a lifting module to lower the entire structure to the ground, reducing the complexity and risk of working at height. By reducing the number and complexity of high-altitude operations, the risks to construction workers are lowered, thereby improving construction safety.
