Description

Technical Field

[0001] This utility model relates to the field of municipal bridge construction technology, and more specifically, to a support bracket for municipal bridge construction. Background Technology

[0002] Support brackets for municipal bridge construction are important temporary support structures used in bridge construction to temporarily bear construction loads, formwork systems, and concrete structures. These support brackets are temporary support systems designed according to the bridge's structural form, primarily used in the construction of cast-in-place concrete beam segments, especially in critical processes such as the pouring of the No. 0 block and the assembly of hanging baskets. Their core function is to provide a stable operating platform for construction, ensuring the stability and safety of the bridge's main structure during construction.

[0003] For example, application number CN202121011837.8 discloses a support bracket for municipal bridge construction. Under the limiting sliding action of the sliding groove on the threaded moving cylinder, the two threaded moving cylinders can move towards or in opposite directions. The rotating support rod rotates synchronously. At the same time, under the telescopic support action of the telescopic rod on the support plate, the support plate moves up and down for support, thereby facilitating quick adjustment of the support and improving construction efficiency. The above device solves the problem that "the current support bracket for municipal bridge construction has a simple structure and is not convenient for quick adjustment of the support, which makes it inconvenient for temporary support work and greatly reduces work efficiency." However, in the prior art, traditional brackets are limited by terrain. When the bracket is used in soft soil, the soft soil foundation needs to be reinforced, which not only increases the number of procedures but also increases construction costs.

[0004] Therefore, a support bracket for municipal bridge construction is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a support bracket for municipal bridge construction to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a support bracket for municipal bridge construction, comprising a pier body, a bridge body, a support frame, an adaptive support base plate, and a connecting frame. One end of the pier body is provided with the bridge body, and the side end face of the bridge body is provided with the support frame. The bottom end face of the support frame is attached to the ground through the adaptive support base plate. The side of the support frame away from the adaptive support base plate is provided with the connecting frame, and the connecting frame is arranged around the pier body.

[0007] The adaptive support substrate includes a basic body and an upper support plate. A cross groove is cut into the lower end face of the basic body, and the upper support plate is fitted into the basic body through the cross groove. A hydraulic cylinder is provided on the bottom end face of the upper support plate. A support block is provided on the telescopic end of the hydraulic cylinder, and a helical pile is provided on the side of the support block away from the hydraulic cylinder. A pressure sensor is provided on the contact surface between the telescopic end of the hydraulic cylinder and the support block.

[0008] Preferably, the support frame includes a first horizontal bar and a first vertical bar. The side end face of the first vertical bar is connected to a reinforcing bar by a high-strength precision-rolled threaded steel bar, and the reinforcing bars are arranged in a crisscross pattern. The support frame is limited and connected to the upper end face of the basic body by a flange.

[0009] Preferably, the connecting frame includes a second horizontal bar and a second vertical bar. The bottom end face of the second horizontal bar is provided with a first connecting block, and the side end face of the first connecting block is provided with the first support bar and the second support bar. The end of the first support bar and the second support bar away from the first connecting block is provided with a second connecting block. The second connecting block is specifically installed on the upper end face of the support frame.

[0010] Preferably, there are several sets of the first horizontal bar and the first vertical bar, and the several sets of the first horizontal bar and the first vertical bar are connected by detachable flanges to form a rectangular frame.

[0011] Preferably, the second horizontal bar and the second vertical bar are provided in several groups, and the several groups of the second horizontal bar and the second vertical bar are connected by detachable flanges to form a trapezoidal frame.

[0012] Preferably, the hydraulic cylinder is connected to an external hydraulic pump via a hydraulic pipe, the pressure sensor is electrically connected to a PLC controller, and the PLC controller is specifically installed on the bottom surface of the adaptive support substrate.

[0013] Preferably, the basic body is provided in several groups, and the groups of basic bodies are fixedly connected by high-strength precision rolled threaded steel. The upper support plate is cross-shaped, and a through hole is drilled through the upper end face of the upper support plate. The upper support plate is fixedly connected to the basic body through the through hole and bolts.

[0014] Preferably, the support frame is connected to the pier body by double-ended studs, and the support frame is connected to the basic body and connecting frame in the adaptive support base plate by high-strength precision-rolled threaded steel.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] Compared with existing technologies, this support bracket for municipal bridge construction uses an adaptive support base plate to support a support frame, which in turn supports a connecting frame, ultimately working on the pier and bridge body. The hydraulic cylinder in the adaptive support base plate drives the support block and helical pile to move up and down, and a pressure sensor detects pressure changes in real time. The helical pile facilitates fixation in soft soil without requiring additional equipment, thus solving the problem that "existing brackets are limited by terrain; when used in soft soil, the soft soil foundation needs additional reinforcement, which not only increases the number of steps but also increases construction costs."

[0017] Compared with existing technologies, this municipal bridge construction support bracket is used in a way that facilitates the operation of the bridge pier and bridge body through the support frame composed of a first horizontal bar, a first vertical bar, and a reinforcing bar, and a connecting frame composed of a second horizontal bar, a second vertical bar, a first connecting block, a first support rod, a second support rod, and a second connecting block. The support frame is connected to the basic body in the adaptive support base plate via high-strength precision-rolled threaded steel and flanges, thus supporting the support frame. A pressure sensor in the adaptive support base plate monitors the pressure between the support frame and the ground in real time. The use of helical piles helps to fix the device to soft soil. The activation of the hydraulic cylinder between the upper support plate and the support block evenly distributes the pressure on the support frame to the ground, thus solving the problem that "existing brackets are limited by terrain; when used in soft soil, the soft soil foundation needs additional reinforcement, which not only increases the number of procedures but also increases construction costs." Furthermore, the distance between the support frame and the ground can be adjusted in real time through the upper support plate, support block, and hydraulic cylinder to provide stable support for the support frame and connecting frame.

They can be customized or selected according to actual needs. Here we only use them and do not make any structural or functional improvements. We will not go into details here.

[0028] The working process of this utility model is as follows: First, the first horizontal bar 31, the first vertical bar 32, and the reinforcing bar 33 form a support frame 3.

The pressure sensor 46 in the adaptive support base plate 4 is real-time. The pressure between the support frame 3 and the ground is monitored. The spiral pile 45 helps to fix the adaptive support base plate 4 to the soft soil. The hydraulic cylinder 43 between the upper support plate 42 and the support block 44 is activated. The pressure on the support frame 3 is evenly distributed to the ground by the upper support plate 42, the support block 44 and the hydraulic cylinder 43.

This solves the problem that "in the existing technology, traditional brackets are limited by the terrain. When the bracket is used in soft soil, the soft soil foundation needs to be reinforced, which not only increases the number of steps but also increases the construction cost".
