End formwork reinforcing device

Abstract

The invention provides an end formwork reinforcing device. The two ends of a supporting rod are fixed to an upper reserved rebar and a lower reserved rebar through a first U-shaped clamping piece, andthe upper reserved rebar and the lower reserved rebar are arranged on an end formwork in a penetrating mode; then, a first inclined strut and a second inclined strut are adjusted to the appropriate angle, the second end of the first inclined strut is detachably connected to the upper reserved rebar through a first fastener, and the second end of the second inclined strut is detachably connected to the lower reserved rebar through a second fastener; when lateral pressure is transmitted in the concrete pouring process, reinforcing of the end formwork is achieved based on the multiple effects ofa fastening joint of the supporting rod, the first inclined strut and the second inclined strut, welding operation on the construction site is reduced, meanwhile, gaskets are arranged at the connection positions between the U-shaped clamping piece and the reserved rebars, and damage to the reserved rebars is decreased.

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.
