Installation of bridge beams is performed using modern cranes, gpm, hydraulic portals and special construction equipment. Concrete beams are used for the construction and reconstruction of bridges, as well as overpasses on road and railway bridges. With their help, adjust the height and curves of the bridge, and they are the main carriers of the load of the entire structure. To date, there are no alternative constructive solutions to bridge beams, and they are made of concrete and steel, high grades.
The process of creating such building elements is complex and time consuming. First, the reinforcement frame of the future beam is assembled, after it is placed in a special form and poured with high-grade concrete with vibration seal. Steel structures are manufactured in stationary conditions with the use of welded and bolt joints, at the facility produces enlarged assembly and subsequent installation in the design position.
BRIDGE BALL TYPES
Professional installation of span structures of the bridge is capable of specialists of the enterprise Synthesis TMK.. The initial data for the work is the construction organization project (POS) and the agreed RRP necessary for the construction of the bridge and highway. It specifies places for storage of materials, products and installation of lifting mechanisms. The type of lifting mechanism of the crane or a group of cranes is selected, as well as methods of mounting bridge beams. In addition, a project of constructive solutions of the KMD and KZH brand is being compiled, in which all configurations, specifics and types of beams, components are calculated and designed.- Iron-concrete structures of taur section are necessary for the installation of span structures of the bridge and have a length of up to 24 meters.
- Bridge beams with a preliminary voltage from the valves their length reaches 36 meters. Such structures are used in span structures that distribute the load on the supports of road and railway overpasses.
- Concrete beams for the construction of pedestrian overpasses, with normal reinforcement, the length of such elements does not exceed 24 meters.
- Beams with double-taur section have a pre-stressed reinforcement and a length of 12 to 36 meters. From such beams, structures are built, the purpose of which is to support the bridge canvas and transfer the received load to the supports of the structure.
The organization of such a process as the transportation of bridge beams due to the large size of these structures is quite complex and time-consuming event that requires the availability of appropriate transport and permits. Logisticians and engineers of Sintez TMK will be able to move with rigging of bridge beams. They comply with the requirements for the storage of materials and products, organize internal quality control of materials for all stages of work.

Contact by phone or send an application by e-mail.Mounting of such large-sized elements as bridge reinforced concrete beams occurs from the ground when a crane or group of cranes is installed on a ground base or from water with a special floating crane. The last way is to assemble the structure from a previously installed span structure. Installation of beams in this case occurs with the help of console and boom cranes.
Installation of bridge beams
The rigging of bridge beams and the work associated with their final installation have a large number of features, the observance of which depends on the outcome of construction and safe operation, such a complex and expensive design as a bridge or highway. It is important to check the quality of beams by instrumental and visual methods, to control the correctness and completeness of the preparation of executive documentation directly at the enterprise where they were produced.- At the first stage, all the necessary documentation is drawn up and a robot production project is drawn up, an installation schedule, full compliance with which ensures the successful completion of the construction.
- The company manufactures beams, the type, size and purpose of which are described in detail in the sections of the project KMD, KZH, according to the PPR.
- Before sending the finished beams to the object right at the plant, their inspection and acceptance for the quality and availability of documents is carried out. Re-checking the condition of the material occurs after their arrival at the construction site in case of defects after transportation, the beams are returned to the manufacturer and replaced.
- The beams are equipped with rafting devices for capture and slinging, then the structure is installed in the design position. After their position is verified by the surveyor, the beams are finally fixed.
- Last phase of work. After lifting the bridge beams is carried out and their fixing is made, execution documentation is drawn up, then tests and commissioning of the finished structure are carried out.
“Synthesis TMK” provides input control of building materials and structures, which allows you to efficiently perform work and invest in time.
Besides, Synthesis TMK. on the construction site carries out incoming control of building materials and structures, which allows you to qualitatively perform work and invest in terms. It is important to pay due attention to geodetic control and drawing up of the PPR, the admission of the slightest error in which can lead to a stoppage of construction for a long period. Company Synthesis TMK. She has the necessary experience, cranes and equipment, which allows her to cope with the tasks associated with the installation, movement and repair of bridge beams of any size, weight and material.
Engineers of the enterprise will make a competent and complete design task for the manufacture of all components, conduct surveys and form a project of production works, advising all technical requirements. If necessary, specialists Synthesis TMK. will perform construction and installation works, including the installation of reinforced concrete beams of span buildings. And then they will conduct acceptance tests, issue executive documentation and put the facility into operation.
The company guarantees the high quality of its work and short deadlines for the execution of works recorded in the PRP.
The company has an integrated approach that allows you to avoid such common mistakes as:
A careful analysis of the initial data, competent PPR and the implementation of control measures allows the enterprise Synthesis TMK. Avoid these and other errors and minimize the risks associated with construction. The presence of engineers and builders of the company a clear work plan allows them to prevent problems of this nature at the construction site and make appropriate adjustments in advance, and it does not matter that this is the dismantling of bridge beams or the construction of new structures.- Violation of terms of supply and manufacture of components;
- Lack of lifting mechanisms of necessary power and other special equipment;
- Conducting work without proper geodetic control;
- Lack of incoming quality control of beams and other elements of the bridge;
- Problems related to logistics;
