Abstract
The utility model relates to a novel roof grid seam. The novel roof grid seam comprises a waterproof layer arranged on a roof screed-coat; a waterproof protective layer is adhered to the waterproof layer; a group of splay angles are uniformly distributed on the waterproof protective layer; polystyrene boards are arranged in gaps of the splay angles; and space between adjacent two splay angles on the waterproof protective layer is filled with concrete. The beneficial effects of the novel roof grid seam are that the novel roof grid seam is easily constructed; the waterproof protective layer is free from damage during a construction process; a traditional construction method is replaced; the novel roof grid seam is easy to operate and attractive in design; investment on labor and materials is reduced; and the novel roof grid seam is economical and environmentally-friendly.
Description
Technical field
The utility model relates to a kind of new type roof dividing joint, belongs to technical field of buildings.
Background technology
In building operations, due to the temperature difference, concrete shrinkage, creep, the impact of the deformation factor such as load and vibration, subsidence of foundations easily causes building rigit waterproof layer cracking, in order to reduce crack, need stay in advance and establish dividing joint at roofing.Roofing dividing joint generally adopts plank isolation to obtain, and is specially and before concreting, installs template, treats that concrete initial set takes out plank and obtains dividing joint after having built; Or after facing concrete has been constructed, carry out joint-cutting, after concrete curing completes, insert encapsulant and obtain dividing joint.This mode working procedure is loaded down with trivial details, time-consuming taking a lot of work, and easily destroy waterproofing course, cause concrete pavement to pollute.
Utility model content
The purpose of this utility model is: the problem existing for above-mentioned prior art, propose a kind of simple in structure, the new type roof dividing joint of easy construction.
In order to reach above object; new type roof dividing joint of the present utility model; comprise the waterproofing course being arranged on roofing leveling layer; on described waterproofing course, be attached with fish tail and waterproof layer; its improvements are; on described fish tail and waterproof layer, uniform one group of splay angle, is provided with polyphenyl plate in the gap of described splay angle, on described fish tail and waterproof layer, between adjacent two splay angles, is filled with concrete.
The utility model further improves, and described splay angle is that leg-of-mutton cement mortar stick is arranged symmetrically with and forms by two cross sections, between described two cement mortar sticks, is filled with polyphenyl plate.
It is that the top of described polyphenyl plate is provided with layer of polyurethane or bitumen layer that the utility model further improves.
It is to be provided with reinforcing bar in described concrete that the utility model further improves.
The utility model has the advantage of: adopt the utility model easy construction, and can not destroy fish tail and waterproof layer in work progress, replaced traditional construction method, simple to operate, be designed beautifully, greatly reduce the input of artificial and material, economic environmental protection.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the cross-sectional view of an embodiment of the utility model.
The specific embodiment
Embodiment mono-
The new type roof dividing joint of the present embodiment; its structure as shown in Figure 1; comprise the waterproofing course 6 being arranged on roofing cement mortar levelling layer 7, on waterproofing course 6, be attached with fish tail and waterproof layer 5, uniform one group of splay angle 4 on fish tail and waterproof layer 5; in the intermediate gap of splay angle 4, be provided with polyphenyl plate 1; polyphenyl plate 1 meets national standard, and its thickness is 2cm, on fish tail and waterproof layer 5, between adjacent two splay angles 4, is filled with concrete; form concrete pavement 3, in concrete, can be provided with reinforcing bar.Wherein, splay angle 4 is that leg-of-mutton cement mortar stick is arranged symmetrically with and forms by two cross sections, and is filled with polyphenyl plate 1 between two cement mortar sticks, and the top of polyphenyl plate 1 is provided with layer of polyurethane or bitumen layer 2.
After roof waterproof topping 5 has been constructed; first on fish tail and waterproof layer 5, having the place of dividing joint to lay cement mortar that splay angle 4(adopts 1:2 is fixed on above fish tail and waterproof layer 5 with the pattern of two-sided splay angle); and the polyphenyl plate cutting 1 is arranged in the intermediate gap of splay angle 4; make the pre-buried roofing that is fixed on of polyphenyl plate 1 and splay angle 4 form dividing joint, spacing is 4 * 4m.Then concreting on fish tail and waterproof layer 5; form in concrete pavement 3(concrete pavement 3 reinforcing bar can be set), after concreting maintenance, without taking out polyphenyl plate 1; directly brushing polyurethane or bituminous liquids above polyphenyl plate 1, obtain layer of polyurethane or bitumen layer 2.Use this dividing joint can not damage fish tail and waterproof layer 5 in work progress; and cement mortar splay angle 4 can firmly be fixed polyphenyl plate 1 and can be used as the absolute altitude control line of concrete pavement 3; because polyphenyl plate 1 self has certain elasticity; not only can solve the harmomegathus problem of roof waterproof topping 5, also not affect concrete finish.Therefore, work progress can not damage and pollute completed surface layer, and dividing joint is straight, attractive in appearance.
In addition to the implementation, the utility model also can have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, drop on the protection domain of the utility model requirement.
Claims (4)
1. a new type roof dividing joint; comprise the waterproofing course being arranged on roofing leveling layer; on described waterproofing course, be attached with fish tail and waterproof layer; it is characterized in that: uniform one group of splay angle on described fish tail and waterproof layer; in the gap of described splay angle, be provided with polyphenyl plate, on described fish tail and waterproof layer, between adjacent two splay angles, be filled with concrete.
