Problems solved by technology

[0004] The above-mentioned prefabricated laminated slabs are first hoisted to the building when in use, and then poured with cement. The cement is used as the adhesive between two adjacent prefabricated laminated slabs. The quantity is limited, and its bonding force is not strong. When the laminated board is subjected to lateral force, it is easy to deviate. Once the laminated board deviates, the casting layer is prone to cracking, which is prone to leakage problems.

Embodiment 1

[0040] Such as figure 1 As shown, a prefabricated laminated board includes a board body 1 and a connecting structure 2. The board body 1 is formed by pouring concrete and is in the shape of a rectangular board. A steel frame 3 is pre-embedded inside the board body 1 .

[0041] The connection structure 2 includes a fitting block 21, a fitting groove 22, a connecting hole 23, a connecting block 24, a connecting piece 25, a connecting ring 26, and a rib hole 27. The fitting block 21 is integrally formed on the board body 1, and on the board Fitting blocks 21 are provided on the four side walls of the body 1; the number of fitting grooves 22 is equal to that of the fitting blocks 21, which are integrally formed on the board body 1 and are located on the same side wall of the board body 1 21 and the fitting groove 22 are adjacent to each other; the fitting block 21 and the fitting groove 22 are paired, and are used for forming an insertion fit between two adjacent boards 1 when the...

Embodiment 2

[0047] Such as figure 2 and image 3 Shown, a kind of prefabrication technology of prefabricated laminated board comprises the following steps:

[0048] (1) Build the frame, lay the steel bars crosswise in the shape of "well", and then use steel wires to bind and position the intersections of two adjacent steel bars, and then weld and reinforce the intersections between the steel bars. At this time, the laminated plate The steel frame is initially formed.

[0049] One thing to note is that in the process of building the frame, a part of the steel bars should be exposed on the side of the frame as the supporting part required to form the fitting block, and then the nuts need to be welded at the end of the supporting part, and the A block of wax is melted in the center of the nut, and the thickness of the wax block is greater than the thickness of the laminated slab when it is finally formed, so that after the steel frame is placed in the mold and concrete is poured, the nut ...

Abstract

The invention discloses a prefabricated laminated slab and a prefabrication process thereof, relates to a building technology, and is used for solving the problem that a common laminated slab is easyto loosen in connection. The laminated slab comprises a slab body and a connecting structure. The connecting structure comprises an embedded block arranged on the slab body, an embedded groove formedin the slab body, a connecting hole formed in the slab body, a connecting block inbuilt in the embedded block and a connecting piece used for matching with the connecting block, the embedded block andthe embedded groove of two adjacent slab bodies are embedded with each other, and the connecting piece penetrate through the connecting hole and then is in threaded connection to the connecting block. The process comprises the following process steps of: building a frame, pouring and forming, demoulding and trimming, and building and maintaining. The prefabricated laminated slab has the followingadvantages and effects that the connecting structures can be used for being connected with each other in the process that two adjacent laminated slabs are spliced with each other, so that when the laminated slabs are subjected to the action of transverse force, the laminated slabs are not prone to being separated from each other, a pouring layer poured on the laminated slabs is not prone to beingseparated, and the purpose of reducing the leakage occurrence probability is achieved.

Description

technical field [0001] The invention relates to building technology, in particular to a prefabricated laminated board and its prefabricated process. Background technique [0002] The laminated slab is an assembled integral floor slab composed of prefabricated slabs and cast-in-place reinforced concrete layers. The laminated slab has good integrity, and the upper and lower surfaces of the slab are flat, which is convenient for decoration of the facing layer. During the construction process, there is no need to build formwork. The construction period is greatly shortened compared with the method of pouring on site, so it has become a common construction method in modern engineering. [0003] At present, the Chinese invention whose authorized notification number is CN207700482U discloses a prefabricated laminated board, which includes a laminated board body, and steel bars are arranged in the laminated board body. The part of the steel bar close to the end of the laminated sla...
