However, in this type of construction method, since the support point of the force-bearing system is on the lower side of the hole, the support system needs to be erected and dismantled. The construction frame body is large, and the work and waste
Especially in this construction method, it can only be constructed layer by layer from bottom to top. Only after the reserved holes in the lower layer are sealed and poured, can the upper layer be built on this basis, and the construction period becomes longer. , seriously affecting the progress of the project

Embodiment
[0026] Embodiment: A suspended formwork structure with a super large reserved opening, including a template 6, an upper stress system and a lower stress system located on the upper and lower sides of the template 6.
[0027] The upper stress system includes several upper main keels 2 and upper sub-keels 3 arranged vertically, the upper main keels 2 are located below the upper sub-keels 3, the upper main keels 2 are evenly placed on the upper part of the reserved opening, and the two ends are supported on the structural floor 1 upper, supporting the upper sub-keel 3;
[0028] The lower stress system includes several lower main keels 11 and lower sub-keels 8 arranged vertically, the lower sub-keels 8 are fixed on the bottom of the formwork 6, and the lower main keels 11 are located at the bottom of the lower sub-keels 8, which are arranged symmetrically with the upper sub-keels 8;
[0029] The upper stress system and the lower stress system are connected by the tension bolt 5, t...

The invention discloses an extra-large reserved hole hanging template structure which comprises a template, an upper stress system and a lower stress system, wherein the upper stress system and the lower stress system are positioned on the upper side and the lower side of the template respectively. The upper stress system comprises a plurality of upper primary keels and a plurality of upper secondary keels which are vertically arranged, the lower stress system comprises a plurality of lower primary keels and a plurality of lower secondary keels which are vertically arranged, a plurality of connectors are connected between the upper stress system and the lower stress system, and the connectors, the upper stress system and the lower stress system are fixedly locked through locking parts. The hanging template structure is different from a traditional bottom supporting structure and belongs to horizontal structure template reinforcement modes, the upper primary keels and secondary keels collectively bear construction loads of the lower stress system, the lower stress system is not depended, different floors can simultaneously construct, working efficiency is improved, and working time is saved.
Description
technical field [0001] The invention relates to the field of reserved hole plugging construction, in particular to a method for hanging formwork at a larger reserved hole in a concrete structure. Background technique [0002] Super-large reserved holes, such as square openings reserved for floor structural slab tower cranes, strip-shaped openings reserved for floor structural slab post-pouring belts, etc., have large concrete structures during later pouring and sealing, which have always been the difficulty and focus of post-construction construction. At present, this kind of reserved hole is mostly sealed after the construction of the main structure is completed, and the micro-expansion concrete is poured, and the bottom formwork is supported by the frame back method, so as to ensure the stability of the support. However, in this type of construction method, since the supporting point of the force-bearing system is on the lower side of the hole, this type of supporting syst...
