Description

Technical Field

[0001] This utility model belongs to the field of prefabricated concrete structure construction technology, specifically relating to a steel frame stiffened composite slab bottom plate splicing template structure. Background Technology

[0002] Composite slabs are the most commonly used components in prefabricated concrete structures in my country. To ensure the integrity of composite slabs, cast-in-place concrete strips are often left between the bottom slabs of the composite slabs to form an integral joint between the bottom slabs.

[0003] To achieve the cast-in-place concrete pouring at the joint of the composite slab bottom plate, additional formwork and supports are required for this area. This is inconsistent with the construction technology that only requires a small amount of necessary support for the bottom plate, resulting in complex on-site formwork support design, difficulty in ensuring construction quality, deformation of the concrete at the joint after demolding, and height difference with the ground on both sides of the bottom plate. These problems have become common quality issues in the field of prefabricated concrete structure construction.

[0004] Therefore, it is necessary to propose a formwork construction technology that is simple to construct and has controllable quality to meet the need for a reasonable and efficient construction of concrete formwork for the bottom joints of composite slabs, improve the current construction technology of prefabricated concrete structures, and promote the good application of composite slab technology. Utility Model Content

[0005] This utility model addresses the common problem of large deformation of the concrete joints in composite slab base plates or significant height differences with surrounding composite slab base plates by providing a steel-framed reinforced formwork structure for composite slab base plate joints. This achieves the combined benefits of simple formwork structure construction and excellent concrete forming quality in the composite slab base plate joints.

[0006] This utility model provides the following technical solution:

[0007] A steel-framed reinforced composite slab bottom plate joint template structure includes a bottom plate, joints, wooden templates, triangular steel frames, bolt holes and bolts. The wooden templates are tightly attached to the bottom of the bottom plate on both sides of the joints, and the triangular steel frames are tightly attached to the wooden templates. The bottom plate, wooden templates and triangular steel frames are fastened together by bolts passing through the bolt holes.

[0008] Preferably, the triangular steel frame is welded together from chords, diagonal members and vertical members, and the chords, diagonal members and vertical members can be made of small-sized steel sections.

[0009] Preferably, the triangular steel frame is set at a certain interval along the length of the joint, and the arrangement of the bolt holes corresponds to the triangular steel frame.

[0010] Preferably, after the wooden formwork and triangular steel frame are spliced ​​and the concrete above the base plate is poured, they can be recycled by loosening the bolts and the exposed bolts can be cut off. Attached Figure Description
