End template reinforcement device

Abstract

The present invention provides a terminal template reinforcement device, the two ends of the support rod and the upper and lower ribs that pass through the terminal template are fixed by the first U-shaped clamping piece, and then the first diagonal brace and the second brace are adjusted. Bracing to a suitable angle, detachably connect the second end of the first diagonal brace to the upper rib through the first fastener, and detachably connect the second end of the second diagonal brace through the second fastener In the lower part of the reinforcement, when there is lateral pressure transmission in the concrete pouring process, the multiple functions of the fastening nodes of the support rod and the first diagonal brace and the second diagonal brace are used to realize the reinforcement of the end formwork, reducing the construction site. Welding operation, at the same time, a gasket is placed at the joint between the U-shaped clamp and the throwing tendon to reduce damage to the throwing tendon.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a terminal formwork reinforcing device. Background technique [0002] Nowadays, domestic subway construction is developing rapidly, and the construction of the second lining structure of subway stations and sections is mostly carried out in separate warehouses due to structural design and construction technology. The construction of the second lining sub-silo often involves the closure of the formwork at the end of the cross section. Because the end formwork has the characteristics of structural ribs and a wide range of formwork closures, it is often difficult to take better formwork reinforcement measures during construction. Usually, steel bars are used. However, the above method has many shortcomings. During the welding operation, it is easy to cause burn damage to the outer waterproof layer, and the welding operation is easy to cause welding damag...

Problems solved by technology

The construction of the second lining sub-silo often involves the closure of the formwork at the end of the cross section. Because the end formwork has the characteristics of structural ribs and a wide range of formwork closures, it is often difficult to take better formwork reinforcement measures during construction. Usually, steel bars are used. However, the above method has many shortcomings. During the welding operation, it is easy to cause burn damage to the outer waterproof layer, and the welding operation is easy to cause welding damage to the structural ribs, and the welding reinforcement Insufficient form precision control, poor inspection of welding and reinforcement effects, frequent welding operations, increased fire hazards on site

[0003] In the process of strengthening the ends of the sub-warehouse construction of underground projects, the traditional reinforcement methods have a particularly large impact on waterproofing and steel reinforcement works, and will cause the end formwork to explode and run out of dust due to insufficient reinforcement, which directly affects the concrete. Construction quality, in order to prevent the occurrence of the above problems, the plugging and reinforcement measures of the end formwork of the separate warehouse construction must be paid attention to and taken seriously

In view of the fact that the traditional method of welding reinforcement with steel rods has very limited effect on the reinforcement of the end formwork, and there are problems such as damage to the waterproof coil of the underground project, damage to the reinforcement, increased fire hazards during welding operations, and poor gas environment quality in the working space.
