Problems solved by technology
Among them, the cast-in-place concrete floor slab has defects such as large amount of consumption, low construction efficiency, and easy cracking; the prefabricated floor slab has defects such as structural integrity and seismic performance inspection; and the assembled integral floor slab has problems such as troublesome construction and difficult guarantee of reliability.
Therefore, laminated floor slabs are widely used as a new type of building board. However, the flat structure of laminated floor slabs makes the butt edges between the boards easy to touch during stacking or hoisting, storage and transportation, or due to padding during stacking. The block elasticity leads to the collision of broken or cracks, so that the overall strength is reduced or even unusable

Embodiment Construction
[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0035] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other co...

The invention discloses a composite floor slab. The composite floor slab comprises lower prefabricated pre-stressed slabs and an upper cast-in-place concrete layer, wherein orthogonal structural ribsand pre-stressed ribs are arranged in the pre-stressed slabs; truss main ribs of the cast-in-place concrete layer is arranged in parallel above the corresponding structural ribs, and the structural ribs and the truss main ribs are connected through uniformly arranging a plurality of connecting hanging and pulling ribs; and the side surfaces of the pre-stressed slabs of the composite floor slab used for butting joint with each other are arc-shaped surfaces, the pre-stressed ribs extend out of the arc-shaped surfaces, and the surface unevenness difference caused by coarse aggregates exposing from concrete on the arc-shaped surfaces of the side surfaces is not less than 4 mm. The arc-shaped side faces formed by water washing after manufactured by arc-shaped side forms greatly reduce the problems of breakage and cracks caused by touching when stacking, hoisting and using the composite floor slab, and the yield is improved.
Description
technical field [0001] The invention relates to the field of construction, in particular to a laminated floor slab, a curved side form for side forming and a preparation method for the laminated floor slab. Background technique [0002] At present, the floor slabs in the construction field mostly adopt structural forms such as cast-in-place concrete floor slabs, prefabricated floor slabs, and assembled integral floor slabs. Among them, the cast-in-place concrete floor slab has defects such as large amount of use, low construction efficiency, and easy cracking; the prefabricated floor slab has defects such as structural integrity and seismic performance inspection; and the assembled integral floor slab has problems such as troublesome construction and difficult guarantee of reliability. Therefore, laminated floor slabs are widely used as a new type of building board. However, the flat structure of laminated floor slabs makes the butt edges between the boards easy to touch dur...
