A die-fixing device used in expressway construction and building engineering construction

Abstract

The invention discloses a mold fixing device used in expressway construction and building engineering construction, which comprises a main fixing plate and an expansion plate, a fixing bar is installed in the middle of one side surface of the main fixing plate, and a fixing bar is installed on one side surface of the fixing bar. There is a first rotating shaft, a diagonal brace is installed at one end of the first rotating shaft, a second rotating shaft is installed at the bottom end of the fixing bar, a bottom horizontal bar is installed at one end of the second rotating shaft, and one side surface of the main fixing plate has four corners The first fixing bolt is provided, and the middle part of both ends of the surface of the other side of the main fixing plate is provided with buckle edges. The inside of the main fixing plate is provided with a chute, and the expansion plate and the main fixing plate are slidingly connected through the chute. In the present invention, by setting a fixed mold device that can be fixed to the ground, after placing the inner formwork, it can be fixed to the ground through the fixed mold device to form a supporting effect on the inner formwork, and the fixed mold device has the function of assembling, It can be easily assembled according to the length of the line during construction, and is convenient for construction and use.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to a mold fixing device used in expressway construction and building engineering construction. Background technique [0002] With the advancement of science and technology and the development of society, municipal roads and civil buildings are gradually being modularized. Modular buildings have the advantages of simple processing, low cost, and can greatly shorten the construction period. In the production process of highway and civil building modules, it is often necessary to use fixed mold devices to realize the pouring of road structure modules. [0003] In the road fixing device, since it involves the pouring of roadside ditches, road surfaces, curved flower beds and rapid flow troughs that are more commonly seen in the municipal and construction fields, it is necessary to use concrete to pour them, and it is more commonly used The formwork structure is generally wooden fo...

Problems solved by technology

[0003] In the road fixing device, since it involves the pouring of roadside ditches, road surfaces, curved flower beds and rapid flow troughs that are more commonly seen in the municipal and construction fields, it is necessary to use concrete to pour them, and it is more commonly used The formwork structure is generally wooden formwork or channel steel, and the support structure is used to support it on the outside to facilitate concrete pouring. However, the existing support structure is only supported by steel anchorage. Extruded deformation caused by pavers and rollers is not well supported

[0004] At the same time, when supporting ditches and other structures for internal mold making, if steel bars are anchored and fixed, the fixing method is point extrusion. For linear slopes, after pouring and forming, it is easy to be deformed due to hot or cold weather, resulting in ditches. The inner wall is not in a straight line, and the middle part will form a wave-shaped curved structure, which is not conducive to the water output of structures such as rapids and sewers. In severe cases, the outlet will be too small to cause blockage, which will affect the drainage effect on the road.
