Example Embodiment

[0024] The present invention will be further described in detail below with reference to the drawings and specific embodiments. According to the following description, the purpose, technical solution and advantages of the present invention will be more clear. It should be noted that the described embodiments are preferred embodiments of the present invention, not all embodiments.

[0025] Combine figure 1 with figure 2 As shown, a new type of modular floor slab includes CLT slab 1, concrete slab 2 and self-tapping screws 3.

[0026] The CLT board 1 is provided with a number of concave grooves 101 spaced apart, the tail of the self-tapping screw 3 is fixed in the concave groove 101, the head of the self-tapping screw 3 is exposed outside the CLT board 1, and the concrete slab 2 Cast on CLT plate 1 and self-tapping screws.

[0027] The distance between adjacent concave grooves 101 is preferably 300 mm to 700 mm.

[0028] The concave grooves 101 are arranged at equal or non-equal int...

Abstract

The invention relates to a novel combined type floor slab and a construction method thereof. The novel combined type floor slab structurally comprises a CLT (Cross Laminated Timber) plate, a concreteplate and self-tapping screws, wherein a plurality of concave grooves are formed in the CLT plate at intervals; the tail parts of the self-tapping screws are fixedly connected into the concave grooves; the heads of the self-tapping screws are exposed out of the CLT plate; the concrete plate is poured onto the CLT plate and the self-tapping screws. According to the novel combined type floor slab provided by the invention, the concave grooves and the self-tapping screws are distributed on the interface of the CLT plate and the concrete plate, so that the CLT plate and the concrete plate have thecommon effect and the rigidity and the bearing capability of a wooden ceiling can be improved, the vibration absorption and sound insulation properties of the wooden ceiling are improved and the fireproof performance of the wooden ceiling is improved; a floor slab solution is provided for developing a wooden structure toward high-rise buildings.

Description

technical field [0001] The invention relates to a novel combined floor slab and a construction method thereof, in particular to a floor slab composed of cross-laminated timber (CLT) and concrete and a construction method thereof, belonging to the technical field of civil engineering. Background technique [0002] Cross-laminated timber (CLT) was first used as a building material in Europe in the 1990s. It is a rectangular shape made of 3 to 9 layers of solid wood sawn timber or structural composite panels orthogonally formed by pressing with structural adhesives. Engineered wood lumber products in , straight and flat lumber forms. Due to the billet assembly process, CLT panels can make full use of small-sized sawn timber, and have good economy and dimensional stability. Since CLT solves the height limit of wooden structures, it can be used to build low, middle and even high-rise residential and non-civilian buildings, and is known as the "second renaissance" of the construc...
