Template supporting device for concrete supporting construction of shaft and lane engineering

Abstract

The invention discloses a template supporting device for concrete supporting construction of shaft and lane engineering and relates to a template supporting device for cast-in-place concrete of shaft and lane engineering. The template supporting device comprises wall templates and a vault template and is characterized in that the template supporting device comprises steel joists and fixing anchor rods, wherein each steel joint comprises a cross arm, stand columns and a vault beam; each fixing anchor rod comprises a rod body, a cover plate and a nut; the steel joints are mounted at intervals in the length direction of the poured concrete roadway, and the rod bodies penetrate through the steel joists and are fixed in surrounding rock; the wall templates and the vault template are laid on two steel joists, concrete is poured between the surrounding rock and the templates, and the wall templates and the vault template are laid sequentially with increasing of height of the poured concrete; the steel joists are dismounted after concrete setting, the concrete surface is covered with the cover plate, and composite supporting is formed. The template supporting device has the advantages that the template supporting device is novel in concept, stable and firm in structure, simple to manufacture, convenient to mount and capable of being repeatedly used and wood materials are saved; the roadway is unimpeded, the construction is convenient, and the production efficiency is improved; the strength of the steel joists is high and integrally connected with the surrounding rock to form a stereoscopic structure, and the strength of the supporting device is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of concrete support, and in particular relates to cast-in-place concrete and reinforced concrete support formwork devices for shaft engineering. Background technique [0002] Cast-in-place concrete and cast-in-place reinforced concrete support is an important structural form in the permanent support of shaft engineering. It is often used in horse head gates, substation chambers, water pump room chambers, and crushing chambers that require higher support levels. The engineering support of wells and roadways with relatively high crushing degree of surrounding rocks. In the traditional cast-in-place concrete support, it is necessary to erect multiple horizontal supports and vertical supports in the roadway to fix the formwork keel, install wall formwork and vault formwork on the keel, and pour concrete. The disadvantage is that the roadway is blocked and takes a long time. It is necessary to wait until the con...

AI Technical Summary

Problems solved by technology

The disadvantage is that the roadway is blocked, and it takes a long time. All the supports need to be removed after the concrete is solidified, and then the next step of excavation or support process is entered. The construction efficiency is low, and the traffic and construction are inconvenient; the horizontal support, vertical support, keel and formwork are multi-purpose Wood production, production and installation are labor-intensive, time-consuming, wood consumption is high, and resources are seriously wasted
