Roof high-low is striden the waterproofing of movement joints node
Technical field
The utility model relates to a kind of buildings waterproof joint structure, relates in particular to a kind of roof high-low for new building and strides the waterproofing of movement joints node.
Background technology
Always arranged dividing of height in adjacent building, stride and just formed roof high-low between the height building roof.And building often can produce distortion under the extraneous factor effect, causes cracking even destruction.So the build joint change that reserves for this situation is called deformation joint.The deformation joint that has between roof high-low is striden need to guarantee waterproof; existing waterproof measure is to adopt coil waterproof layer to carry out the just linking between the building; cover deformation joint by coil waterproof layer; then be fixed in coil waterproof layer in the groove of high building by press strip; be at last the protection coil waterproof layer, need to cover by iron sheet again and block that the loaded down with trivial details and iron sheet of whole construction is through the bad weather such as drenching with rain in the above; easy oxidation scission, the life-span is not long.
The utility model content
The purpose of this utility model is to solve above-mentioned technical problem, provides a kind of roof high-low to stride the waterproofing of movement joints node.
The purpose of this utility model is achieved through the following technical solutions:
Roof high-low is striden the waterproofing of movement joints node, comprise the first building and the second building, has difference in height between described the first building and the second building, and be provided with deformation joint between described the first building and the second building, be provided with reinforced concrete soil pressure eaves on described the first external wall, described reinforced concrete soil pressure eaves goes out to extend to the top of the second building parapet to the exterior wall evagination.
Preferably, be coated with floated coat on the described reinforced concrete soil pressure eaves, the bottom of described floated coat becomes the angle setting, and the end face of described floated coat and the angle on inclined-plane are less than 90 °.
Preferably, the end face of described the second building parapet is fixed with anticorrosion batten, be connected by fluid sealant between described anticorrosion batten and the floated coat, be provided with waterproofing course between described parapet and the second building roof, the logical closing in press strip of one end of described waterproofing course is pressed abd fixed on the described anticorrosion batten, the other end is connected by the coil waterproof layer of hot air welding and waterproofing course below, described reinforced concrete soil pressure eaves extend to waterproofing course on the parapet directly over.
Preferably, described deformation joint is the shrinkage joint.
The beneficial effects of the utility model are mainly reflected in: extend be used to the pressure eaves that blocks deformation joint by the exterior wall from high building, gear presses eaves to extend low building parapet top simultaneously, waterproofing course on the parapet closed up also to have well block easy construction, good water-proof effect.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1: structural representation of the present utility model.
The specific embodiment
The utility model has disclosed roof high-low and has striden the waterproofing of movement joints node, comprises the first building and the second building.Have difference in height between described the first building and the second building, and the first building is higher than the second building, described the first building and second is provided with deformation joint between building.Deformation joint described in the utility model is the shrinkage joint.
Combination is shown in Figure 1, is provided with reinforced concrete soil pressure eaves 11 on the exterior wall 1 of described the first building, and described reinforced concrete soil pressure eaves 11 extends to the top of the second building parapet 2 to exterior wall 1 outer protrusion.Owing to be that the utility model is that new building is carried out the waterproof purpose, can not cause the puzzlement that is difficult for connection.
Be coated with floated coat on the described reinforced concrete soil pressure eaves 11.Prolong to the first external wall lateral bine for fear of water, the bottom of described floated coat becomes the angle setting, and the end face 13 of described floated coat and the angle on inclined-plane 12 are less than 90 °.
Form between floated coat and the parapet 2 and be tightly connected.Concrete, the end face of described the second building parapet 2 is fixed with anticorrosion batten 21, is tightly connected by fluid sealant 22 between described anticorrosion batten 21 and the floated coat.Like this.Enter into deformation joint even there is water also not have the space.
Be provided with waterproofing course 3 between the roofing of described parapet 2 and the second building, the logical closing in press strip of one end of described waterproofing course 3 presses (meaning not shown in the figures) to fasten on described anticorrosion batten 21, and the other end is connected by the coil waterproof layer 4 of hot air welding with waterproofing course 3 belows.Other techonospheres of building described in the utility model and the concrete fixed form of described coil waterproof layer 4 are all consistent with prior art, do not repeat them here.
Certainly, in order better waterproofing course 3 to be had protective effect, described reinforced concrete soil pressure eaves 11 needs to extend the top that is arranged on waterproofing course 3.
The utility model still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of the utility model.
