Description

Technical Field

[0001] This utility model relates to the field of bridge construction, specifically to a support device for bridge construction. Background Technology

[0002] During bridge construction, especially for the construction of bridge piers, temporary support platforms are often needed to accommodate personnel operations, material storage, and equipment placement. Traditional support systems typically utilize scaffolding or custom-made steel supports, but these structures have several limitations:

[0003] On the one hand, scaffolding systems need to be erected layer by layer from the ground, which not only consumes a lot of materials and has a long construction period, but is also significantly affected by the height and cross-sectional shape of the piers, making it difficult to ensure a stable connection between the support platform and the piers, thus posing safety hazards. At the same time, the load-bearing capacity of scaffolding is limited, which cannot meet the placement requirements of large construction equipment, thus restricting the improvement of construction efficiency.

[0004] On the other hand, while customized steel supports can adapt to specific pier structures to a certain extent, they have poor versatility. Moreover, their installation process relies heavily on welding and fixing, making on-site operations difficult. Dismantling them later also requires cutting operations, which is not only time-consuming and labor-intensive, but may also damage the surface of the pier.

[0005] In addition, the height adjustment of existing support platforms mostly adopts manual prying or mechanical hoisting methods, which have low adjustment accuracy and are cumbersome to operate, making it difficult to flexibly adjust the working height according to the construction progress. At the same time, the connection stability between the platform and the support structure is insufficient, and it is prone to displacement due to factors such as vibration and load changes in high-altitude working environment, which affects construction safety.

[0006] In addition, traditional support platforms are mostly enclosed structures, which have problems such as excessive weight and poor drainage. Furthermore, the poor ventilation of enclosed platforms is detrimental to the health of workers at heights.

[0007] Therefore, developing a support device that can be quickly installed, flexibly adjusted in height, and has strong stability is key to solving the support problem in bridge pier construction. It is of great significance for improving construction efficiency, reducing safety risks, and saving project costs. Utility Model Content

[0008] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a support device for bridge construction; it is a support device that can be quickly installed, has flexible height adjustment, and is highly stable.

[0009] This utility model is implemented as follows: a support device for bridge construction is constructed, characterized in that it includes annular positioning seats for fixing to bridge piers, with two sets of jacks fixedly installed on each annular positioning seat. The two sets of jacks correspond to the two sides of the bridge pier respectively. Supporting steel is mounted on the jacks, and a construction support platform is fixed on the supporting steel. The construction support platform forms a relatively wide construction area, which can be used as an operating platform during bridge construction. Together with the two sets of supporting steel, it constitutes the main support body for bridge construction, which can be lifted by the jacks.

[0010] According to the present invention, a bridge construction support device is characterized in that: a connecting through hole is provided on the supporting steel, and two sets of horizontal supporting steel are connected by a screw. The two ends of the screw are threaded, so that the two ends of the screw pass through the connecting through hole and are then locked by a nut. The screw can connect the two sets of supporting steel into a whole, which facilitates the adjustment of the spacing between the two sets of supporting steel, and also facilitates the confinement of the two sets of supporting steel around the bridge pier.

[0011] According to the present invention, a bridge construction support device is characterized in that the construction support platform is a mesh platform.

[0012] According to the present invention, a bridge construction support device is characterized in that: the annular positioning seat is composed of two sets of semi-circular positioning blocks joined together, the ends of the semi-circular positioning blocks are fixed by bolts, and the joined ends are used to form a fixed installation platform for the jack; multiple positioning holes are opened around the semi-circular positioning blocks, and positioning pins are inserted into the positioning holes along the bridge pier, and the annular positioning seat is fixed to the bridge pier by the positioning pins.

[0013] According to the present invention, a bridge construction support device is characterized in that the construction support platform and the support steel are fixed together by steel wire binding or bolts.

[0014] Compared with existing technologies, the support equipment used in this bridge construction has the following significant advantages:

[0015] (1) Convenient and efficient installation and disassembly, with strong adaptability: The circular positioning seat is composed of two sets of semi-circular positioning blocks. The ends are fixed by bolts and can be quickly fixed on the bridge pier with positioning pins. There is no need to build it layer by layer from the ground, which greatly shortens the installation cycle. At the same time, this combination structure can be adapted to bridge piers of different diameters. When the size of the pier changes, only the degree of closure of the semi-circular positioning blocks needs to be adjusted, which solves the problem of poor universality of traditional customized steel brackets and reduces the replacement cost of the equipment.

[0016] (2) The support structure is stable, reliable, and highly safe: The two sets of horizontal support steel sections are connected as a whole by screws. The threads at both ends of the screws cooperate with the nuts, which not only allows for flexible adjustment of the spacing between the two sets of support steel sections to ensure that they are tightly confined around the bridge piers, but also enhances the overall rigidity of the support structure, effectively resisting vibrations and load changes during construction and preventing displacement of the support platform. In addition, the construction support platform adopts a mesh structure, which ensures good ventilation and rapid drainage, reducing the risk of slipping due to water accumulation during the rainy season. At the same time, the mesh structure is lightweight, reducing the load on the support structure and further improving overall safety.

[0017] (3) The height adjustment is flexible and precise to meet the construction needs: The main support can be lifted by jacks. Compared with the traditional manual prying or mechanical hoisting adjustment method, it is easier to operate and has higher adjustment accuracy. The height of the support platform can be adjusted at any time according to the construction progress, which provides convenience for construction operations at different stages and significantly improves construction efficiency.

[0018] (4) Diverse and stable connection methods with wide adaptability: The construction support platform and the support steel can be fixed by steel wire binding or bolts. The two connection methods can be flexibly selected according to the construction scenario, which not only ensures the stability of the connection, but also improves the adaptability of the equipment under different construction conditions. At the same time, the cooperation between the screw and the connecting through hole on the support steel makes the spacing adjustment of the support steel not limited by the cross-sectional shape of the pier, and can achieve stable support for both circular and irregular shaped piers.

[0019] (5) Excellent economy and practicality: All components of the equipment are made of conventional steel, screws, jacks and other materials, which are low in manufacturing cost and easy to procure; the mesh construction support platform reduces the amount of materials used and lowers the weight and manufacturing cost of the equipment while ensuring load-bearing capacity. In addition, the components of the equipment can be reused. After the project is completed, they can be disassembled and transported to the next construction site for continued use, reducing resource waste and further reducing construction costs.

[0023] The following will be combined with the appendix Figures 1-3This utility model will be described in detail, and the technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0024] This utility model provides a support device for bridge construction, such as... Figures 1-3 As shown, it can be implemented in the following manner: including annular positioning seats 2 for fixing on bridge pier 1, two sets of jacks 3 are fixedly installed on each annular positioning seat 2, the two sets of jacks 3 correspond to the two sides of the bridge pier 1 respectively, the jacks 3 are supported by supporting steel 4, and the supporting steel 4 is fixed with a construction support platform 5; the construction support platform 5 forms a relatively wide construction area, which can be used as an operating platform during bridge construction, and together with the two sets of supporting steel 4, it constitutes the main support body for bridge construction, which can be lifted by the jacks 3.

[0025] like Figures 1-3 As shown in this application, the supporting steel 4 has a connecting through hole 4-1. The two sets of horizontal supporting steel 4 are connected by a screw 6. The two ends of the screw 6 are threaded, so that the two ends of the screw 6 pass through the connecting through hole 4-1 and are then locked by a nut. The screw 6 can connect the two sets of supporting steel 4 into a whole, which makes it easy to adjust the spacing between the two sets of supporting steel 4, and also makes it easy to limit the two sets of supporting steel 4 around the bridge pier 1.

[0026] like Figures 1-3 As shown in the figure, in this application, the construction support platform 5 is a mesh platform.

[0027] like Figures 1-3 As shown in this application, the annular positioning seat 2 is composed of two sets of semi-circular positioning blocks 2-1 joined together. The ends of the semi-circular positioning blocks 2-1 are fixed by bolts 7, and the joined ends are used to form a fixed installation platform for the jack 3. The semi-circular positioning blocks 2-1 have multiple positioning holes 2-2 around their perimeter. Positioning pins 2-3 are inserted into the bridge pier 1 through the positioning holes 2-2, and the annular positioning seat 2 is fixed to the bridge pier 1 by the positioning pins 2-3.

[0028] like Figures 1-3 As shown in this application, the construction support platform 5 and the support steel 4 are fixed together by steel wire binding or bolts.

[0029] The following describes the implementation process of the support equipment used in the construction of this bridge:

[0030] First, install the annular positioning seats: Drill holes at corresponding locations on the bridge pier, and bring two sets of semi-circular positioning blocks together from both sides of the bridge pier, aligning their ends to form a circular structure. Insert positioning pins into the bridge pier to securely fix the annular positioning seats to the pier. Next, use bolts to fix the ends of the semi-circular positioning blocks, creating a fixed mounting platform for the jacks at the joined ends. After installing the annular positioning seats, install the jacks. On the fixed mounting platform formed by the joined ends of the annular positioning seats, fix two sets of jacks to the corresponding sides of the bridge pier.

[0031] Next, install the supporting steel sections: Place the supporting steel sections above the jacks, ensuring their accurate positioning. Then, using the connecting through holes on the supporting steel sections, connect the two horizontal sets of supporting steel sections with threaded rods. Specifically, pass both ends of the threaded rods through the connecting through holes of the two sets of supporting steel sections. Since both ends of the threaded rods have threads, tighten them with nuts after passing through the through holes. In this way, the two sets of supporting steel sections are connected as a whole. Adjust the spacing between the two sets of supporting steel sections according to the actual dimensions of the bridge pier, limiting their position around the bridge pier.

[0032] Then, a construction support platform is erected: the construction support platform is a mesh platform, which is placed on the supporting steel. Depending on the actual construction needs, the construction support platform is firmly connected to the supporting steel by means of wire binding or bolt fixing, forming a wider construction area, which serves as an operating platform during bridge construction.

[0033] During construction, if it is necessary to adjust the height of the support platform, the jacks are activated to lift the main support structure, which consists of two sets of supporting steel sections and the construction support platform, until the required height is reached.

[0034] After construction is completed, dismantle the equipment in the reverse order of installation. First, disconnect the connection between the construction support platform and the supporting steel, and remove the mesh construction support platform. Then, loosen the nuts at both ends of the screw rod and remove the screw rod from the connecting through hole of the supporting steel, separating the two sets of supporting steel. Next, remove the jack, then pull out the positioning pin, unscrew the bolts fixing the ends of the semi-circular positioning blocks, separate the two sets of semi-circular positioning blocks, and remove them from the bridge pier, completing the dismantling of the entire equipment.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
