Description

Gridding supporting structure for hole template Technical Field The invention relates to the technical field of building construction, in particular to a gridding supporting structure for an opening template. Background In the building construction process, templates are usually required to be arranged for the opening parts in the structures such as walls, floors and the like so as to finish concrete pouring molding. In order to ensure the size and the forming quality of the hole, the template is required to be reliably supported on the inner periphery of the hole and is kept in a stable state in the construction process. In the prior art, the supporting mode of the hole template mainly comprises the supporting mode of adopting a square timber, a steel pipe or a single supporting rod, and the supporting mode is usually used for supporting and fixing the template through a small number of supporting points. The method is simple in structure, but has the defects that on one hand, due to the fact that the distribution of supporting points is discrete, a continuous supporting structure is lacking in a formwork, overall stress is uneven, local deformation and even displacement are easy to generate in the concrete pouring process, so that the forming precision of a hole is affected, on the other hand, the traditional supporting structure is mainly a member with a fixed length or a limited adjusting range, quick adaptation is difficult to be carried out according to holes with different sizes, on-site cutting or member replacement is usually needed, the construction efficiency is low, and for holes with larger sizes, a stable stress system is difficult to form only by means of small amount of internal support, extra diagonal braces or temporary reinforcing structures are often needed to be added, the construction complexity is increased, the connection reliability of the overall structure is poor, and the stability is still difficult to effectively guarantee. Disclosure of Invention The invention aims to overcome the defects of the prior art, provides a gridding supporting structure for a hole template, forms an internal grid framework through a cross-shaped support and a connecting piece, and realizes uniform jacking of a template frame body by matching with a splayed support, thereby solving the problems of insufficient rigidity, easy deformation, poor universality and inconvenient disassembly and assembly of the traditional hole support. In order to achieve the above purpose, the technical scheme adopted by the invention is a gridding support structure for an opening template, comprising: The template frame body is used for being arranged around the inner periphery of the hole; the grid-shaped supporting structure is arranged in the template frame body and comprises a plurality of cross-shaped supporting structures and a plurality of first connecting pieces, wherein the first connecting pieces are used for connecting every two cross-shaped supporting structures together so as to realize the connection of the plurality of cross-shaped supporting structures into the grid-shaped supporting structure; The splayed support structures are supported between the periphery of the grid-shaped support structure and the inner periphery of the template frame body at intervals, each splayed support structure comprises two support rods which are arranged at an included angle, one ends of the two support rods are intersected and connected with the cross-shaped support structure at the outer side of the grid-shaped support structure through a second connecting piece, the other ends of the two support rods are respectively propped against different positions of the template frame body, The length of the support rod and the first connecting piece is adjustable.
