AI Technical Summary
In subway construction, the insecure reinforcement of small-section formwork leads to inaccurate formwork positioning, deformation, displacement, misalignment, uneven joints, dimensional encroachment, and poor overall alignment of the secondary lining. Moreover, the construction cost of dealing with such problems is high.
The template reinforcement structure adopts L-shaped hooks and steel plate clamps. The L-shaped hooks are hooked into the connecting bolt holes of the spliced steel templates, and the steel plate clamps are connected to the keel to form multiple connections, which enhances the stability of the templates. The position can be adjusted by nuts, which is suitable for different models of spliced steel templates.
It achieves stable fixation of the template, avoids displacement and deformation, simplifies position adjustment, reduces construction costs, and provides convenient on-site applicability and recyclable materials.

[0005] Further, the back of the spliced steel formwork is crossly arranged with a main keel and a secondary keel, the secondary keel is pressed on the main keel, the secondary keel is parallel to the spliced steel formwork, and the steel plate fixture is vertically placed on the secondary keel.
[0006] Further, the hook body of L type draw hook is hooked into the connecting bolt hole of two adjacent spliced steel formworks.
[0007] Further, at least two formwork reinforcing structures are arranged on the same spliced steel formwork.
[0008] Further, the rod body of L type draw hook is marked with external threads, the anti-drop part is a nut, and the nut is screw-coupled with the rod body.
[0009] Further, the mounting hole of the steel plate fixture is a long hole parallel to the long side of the steel plate fixture.
[0010] Compared with the prior art, the utility model has the advantages that:
[0011] The utility model provides a kind of formwork support construction tunnel lining's formwork reinforcing structure, simple structure, reasonable in design, by installing reinforcement in different height, different position, unified axis, it realizes the multiple connection of L type draw hook and steel plate fixture, the strength of formwork reinforcement is improved, the phenomenon of formwork displacement, deformation, uneven stress is prevented from happening;When the size of formwork, position is not suitable, when formwork position is adjusted, only need to be adjusted after the nut that cooperates with steel plate fixture is removed, it is convenient and fast;By the installation hole drilled in advance, and the cooperation of L type draw hook and installation hole, it can be applicable to different models of spliced steel formwork, provide convenient conditions for on-site use;L type draw hook, steel plate fixture and other components are made of on-site material, not only convenient to disassemble, simple to make, and from long-term interests, can be recycled as turnover material, save a lot of cost.
