Description

TECHNICAL FIELD

[0001] The utility model relates to a roof waterproof protective layer, especially to a large roof fine stone concrete waterproof protective layer structure which can effectively prevent cracking. BACKGROUND

[0002] The roof surface of some cast-in-place concrete frame structure large workshop is cast-in-place concrete pouring structure layer, and structure leveling layer, heat preservation layer, slope finding layer, waterproof leveling layer, waterproof layer, isolation layer and fine stone concrete protective layer are respectively applied on the structure layer, wherein the fine stone concrete protective layer is applied by first laying the isolation layer on the waterproof layer, then laying the steel mesh, and finally pouring the fine stone concrete protective layer, so as to form the large roof surface layer; the fine stone concrete protective layer is needed to be set on the large roof surface layer to make the roof overall beautiful and prevent the fine stone concrete protective layer from cracking irregularly; when the roof area is large, the steel mesh needs to be laid on the waterproof layer by splicing, generally 6m*6m steel mesh is used, and the meshes are connected together before laying; the fine stone concrete is poured on the laid steel mesh; when the fine stone concrete protective layer is poured, the separation joint on it is generally left according to the roof area and overall beauty; after the roof surface layer is completed, irregular cracks often appear on the surface layer due to the expansion of the steel mesh in a short time, which affects the beauty of the roof and causes quality problems; how to solve the above problems has become a problem to be solved in the field construction. SUMMARY

[0003] The utility model provides a large roof fine stone concrete waterproof protective layer structure which can effectively prevent cracking, and solves the technical problem that the large roof surface layer is prone to cracking.

[0004] The utility model solves the above technical problems through the following technical scheme:

[0005] A large roof fine stone concrete waterproof protective layer structure which can effectively prevent cracking comprises a roof waterproof protective layer, an isolation layer is arranged on the roof waterproof protective layer, longitudinal division joint templates and transverse division joint templates are arranged on the isolation layer, the longitudinal division joint templates and the transverse division joint templates form a grid-shaped space, a rectangular steel mesh is arranged in each rectangular frame of the grid-shaped space, and fine stone concrete is poured on the rectangular steel mesh.

[0006] After the poured fine stone concrete solidifies and the longitudinal division joint templates and the transverse division joint templates are removed, the longitudinal division joint of the roof surface layer, the transverse division joint and the rectangular fine stone concrete surface layer are formed.

[0007] The utility model unifies the consideration of the division joint on the fine stone concrete surface layer on the large roof and the reinforcing mesh pre-buried in the fine stone concrete, and sets up correspondingly, makes the expansion of the reinforcing mesh complete in the rectangular grid in the longitudinal and transverse division joints, realizes the corresponding setting of the rectangular fine stone concrete surface layer and the pre-buried reinforcing mesh, overcomes the cracking of the large roof surface layer, and improves the waterproof and the appearance of the roof surface. BRIEF DESCRIPTION OF DRAWINGS

[0008] Figure 1 It is the structural schematic diagram of the utility model;

[0009] Figure 2 It is the roof surface structure schematic diagram of the utility model after the construction is completed. CONCRETE EMBODIMENT

[0010] The utility model will be described in detail below in combination with the drawings:

[0011] A kind of large roof fine stone concrete waterproof protective layer structure that can effectively prevent cracking, including roof surface waterproof protective layer, isolation layer is set on roof surface waterproof protective layer, longitudinal division joint formwork 2 and transverse division joint formwork 3 are set on isolation layer, longitudinal division joint formwork 2 and transverse division joint formwork 3 form grid-like space, rectangular reinforcing mesh 4 is set in each rectangular frame 1 in grid-like space, fine stone concrete is poured on rectangular reinforcing mesh 4;Rectangular reinforcing mesh 4 and the fine stone concrete poured on it are set correspondingly, division joint formwork is set at the periphery of rectangular reinforcing mesh 4, when pouring concrete solidifies, remove division joint formwork and form rectangular grid unit, the expansion of reinforcing mesh pre-buried in this cell is completed in rectangular grid, will not cross over division joint, so that the probability of rectangular surface layer cracking is greatly reduced.

[0012] When the fine stone concrete poured solidifies and removes longitudinal division joint formwork 2 and with transverse division joint formwork 3, form the longitudinal division joint 6 of roof surface layer, transverse division joint 7 and rectangular fine stone concrete surface layer 5.

[0013] Site construction process is:

[0014] First step, on large area roof, construction waterproof layer is made, and closed water leak detection is made;

[0015] Second step, full-paved isolation layer is on waterproof layer;

[0016] Third step, according to the length and width of roof surface grid, isolation joint formwork is set;

[0017] Fourth step, reinforcing mesh is made according to grid size, and reinforcing mesh is placed into grid;

[0018] Fifth step, fine stone concrete is poured, and roof surface layer is formed;

[0019] Sixth step, cutting the division joint, taking out the division joint template, forming longitudinal and transverse division joints;

[0020] Seventh step, after the fine stone concrete shrinks stably, use weather-resistant structural adhesive to caulk.
