Embodiment Construction

[0026] Refer to the attached figure 1 to attach Figure 13 The joint reinforcement structure of prefabricated unidirectional laminated boards of the present invention will be described in detail below.

[0027] The joint reinforcement structure of the prefabricated one-way laminated slabs of the present invention comprises more than two prefabricated slabs 1, and at the joint between two adjacent prefabricated slabs 1, a connection steel bar 2 is reserved for one, and a groove is reserved for the other 3. The connecting steel bars 2 include multiple connecting steel bars 2 respectively extending into the groove 3 and matching with the groove 3 , and the ends of the connecting steel bars 2 are connected by a structural steel bar 4 .

[0028] The groove 3 includes a parallel groove 31 parallel to the connecting steel bar 2 and a vertical groove 32 perpendicular to the connecting steel bar 2. The parallel groove 31 includes a plurality of vertical grooves 32 located at the ends ...

Abstract

The invention discloses a prefabricated one-way laminated slab abutted seam reinforcing structure, and belongs to the field of fabricated buildings. The prefabricated one-way laminated slab abutted seam reinforcing structure structurally comprises two or more prefabricated slabs, wherein a plurality of connecting steel bars are reserved at the abutted seam position of every two adjacent prefabricated slabs, a groove is reserved in the abutted seam position of every two adjacent prefabricated slabs, the connecting steel bars extend into the grooves respectively and are matched with the grooves,and the ends of the connecting steel bars are connected through a constructional steel bar. Compared with the prior art, the prefabricated one-way laminated slab abutted seam reinforcing structure has the advantages that the problems that slab seam gaps are widened and cracked due to the fact that one-way slab abutted seams are subjected to loads are solved, and therefore the prefabricated one-way laminated slab abutted seam reinforcing structure has very good application and popularization value.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to a joint reinforcement structure of prefabricated one-way laminated boards. Background technique [0002] With the vigorous development of prefabricated buildings, the application of horizontal prefabricated components in concrete structures has become more common. As a horizontal prefabricated component that is widely used at present, laminated slabs are usually designed into two-way slabs and one-way slabs according to the stress situation. Most of the existing designs of the seams between the unidirectional slabs use two unidirectional slabs to directly join together to form a dense seam, or leave a 30-50mm post-casting small seam between the two unidirectional slabs. A section of structural steel reinforcement is designed above the slab joints, and there is no relatively reliable connection measure for the gap between the two slabs. There are no relatively reliable conn...
