Description

Technical Field

[0001] The utility model relates to the field of roadbed construction templates, in particular to a connection structure of roadbed construction templates. Background Art

[0002] The connection structure of the roadbed construction formwork is a key part to ensure the quality and safety of construction. When designing this connection structure, many factors need to be considered, including the practicality, safety and economy of the formwork. First of all, from the perspective of practicality, the connection structure of the formwork needs to ensure that the joints are tight to prevent leakage, and at the same time ensure the correctness of the shape, size and relative position of each part of the concrete structure and components. Secondly, safety is another important consideration. The connection structure of the formwork must have sufficient bearing capacity and rigidity to maintain stability under various loads and prevent damage and collapse; finally, economy is also a factor that needs to be considered when designing the formwork connection structure. Under the premise of ensuring practicality and safety, the one-time investment in the formwork should be reduced as much as possible, the turnover speed of the formwork should be accelerated, the labor for support and dismantling should be reduced, and the self-weight of the formwork structure should be reduced. In practical applications, the appropriate connection method can be selected according to the specific engineering requirements and construction conditions, and necessary optimization and improvement can be carried out to improve construction efficiency and quality;

[0003] In the prior art, the connection structure of the roadbed construction template is composed of a roadbed template, a support plate, a fixed plate, a connecting plate, a connecting column and two fixed columns. The support plate, the fixed plate, the connecting plate and the connecting columns are fixedly connected. The two fixing columns pass through the through holes opened on the connecting columns and extend to the inside of the through holes opened in the vertical direction of the roadbed template. During use, during installation, the fixing columns must first be inserted through the through holes of the connecting columns and then through the through holes of the roadbed template, which requires multiple alignments, which is inconvenient to operate. Secondly, the two fixing columns are independent individuals and have a circular cross-section, and the fixing columns are used in combination with the support plates, the fixed plates, the connecting plates and the connecting columns. If the fixing columns are accidentally lost, the supporting plates, the fixed plates, the connecting plates and the connecting columns used in combination with them will lose their original uses.

[0004] Therefore, it is necessary to provide a new connection structure of roadbed construction template to solve the above technical problems. Utility Model Content
