Description
Technical field
This utility model relates to buildings in general, is specially a kind of Assembled prefabricated stair module.
Background technology
Owing to cast-in-site stair exist more deficiency, therefore, this area provided the multiple technical scheme of industrialization making stair product in factory in recent years, in order to be directly installed on building use.But this stair are not yet approved by this area at present, it main reason is that: pre-stair weight is relatively big, loads and unloads and installs complexity, and the production cost making precast stair is higher than cast stair.Although the advantage of precast stair is a lot, but owing to it exists handling, installs complicated deficiency, existing precast stair product is made to promote the use of.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Assembled prefabricated stair module being easily installed and transporting.
For solving the problems referred to above, technical solution adopted in the utility model is:
A kind of Assembled prefabricated stair module, its key technology is: it stair gripper shoe including concreting and the multiple step plates being fixedly installed in described stair gripper shoe, described stair gripper shoe includes the support plate body tilted and is arranged on described support plate body two ends horizontal-extending lower carrier and upper carrier, it is provided with lightening hole in described stair gripper shoe and step plate, in described lightening hole, is lined with steel pipe.
As further improvement of the utility model, described step plate is the strip shape body that cross section is triangular in shape, and step plate is bolted in described stair gripper shoe.
As further improvement of the utility model, described step plate is wooden structures or lightweight steel construction.
As further improvement of the utility model, being provided with steel pipe skeleton in described stair gripper shoe, described steel pipe skeleton includes some support beams that the support column that two or more is arranged side by side is arranged on described support column with welding.
As further improvement of the utility model, described support column and support beam all use square steel tube.
As further improvement of the utility model, on described steel pipe skeleton, welding is provided with multiple peg.
Use and have the beneficial effects that produced by technique scheme:
This utility model will arrange lightening hole in the support plate body of stair and step plate, and in lightening hole, display steel pipe, on the one hand the molding of lightening hole is facilitated, on the other hand can play a supporting role, strengthen its intensity, avoiding being ruptured by lightening hole, the setting of lightening hole reduces the weight of whole precast stair, it is simple to lifts by crane, install and transports.
Support plate body and the step plate split of stair are arranged so that the structure of stair gripper shoe is simpler, and its top and bottom are smooth, pour simplicity, conveniently laying when transport, take up room little.Step plate split design can alleviate the weight of stair gripper shoe, and convenient concentration of step plate arranges and transport.Whole stair gripper shoe is greatly saved the working time when playing sling cart and lifting is installed, and reduces working strength.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model detailed description of the invention or technical scheme of the prior art, the accompanying drawing used required in detailed description of the invention or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of this utility model steel pipe skeleton.
Wherein: carrier under 1 stair gripper shoe, 1-1 support plate body, 1-2, the upper carrier of 1-3,1-4 support column, 1-5 support beam, 1-6 service sleeve, 1-7 depressed part, 1-8 pre-buried connecting plate A, 1-9 pre-buried connecting plate B, 2 step plates, 2-1 lightening hole, 3 fix bolt, 4 suspension ring.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, 1-2 and specific embodiment carry out clear, complete description to utility model below in conjunction with the accompanying drawings.
A kind of Assembled prefabricated stair module as shown in Figure 1, it stair gripper shoe 1 including concreting and the multiple step plates 2 being arranged in described stair gripper shoe 1, described step plate 2 is the strip shape body that cross section is triangular in shape, step plate 2 is bolted in described stair gripper shoe 1, pre-buried connecting plate A1-8 and pre-buried connecting plate B1-9 it is provided with in described stair gripper shoe 1, described pre-buried connecting plate A1-8 is vertically arranged, described pre-buried connecting plate B1-9 is horizontally disposed with, described step plate 2 is connected with described pre-buried connecting plate A1-8 and pre-buried connecting plate B1-9 by fixing bolt 3.
It is provided with lightening hole 2-1 in described stair gripper shoe 1 and step plate 2, it is lined with steel pipe in described lightening hole 2-1, as shown in the figure, described step plate 2 is provided with lightening hole 2-1 in its longitudinal direction, step plate 2 can arrange multiple lightening hole 2-1, can be substantially reduced the weight of step plate 2, reduce the heavy burden of stair gripper shoe 1, described step plate 2 is concreting molding or uses lighter wooden structures.
Described stair gripper shoe 1 includes support plate body 1-1 tilted and is arranged on described support plate body 1-1 two ends horizontal-extending lower carrier 1-2 and upper carrier 1-3, is provided with steel pipe skeleton in described stair gripper shoe 1.
As in figure 2 it is shown, described steel pipe skeleton includes that the support column 1-4 that two or more is arranged side by side is arranged on some support beams 1-5 on described support column 1-4 with welding.Described support column 1-4 uses together with pipe or square tubes soldering with support beam 1-5, forms steel pipe skeleton, owing to steel pipe skeleton takies more space so that the unit weight reduction of stair gripper shoe 1, therefore makes its weight reduction, convenient transport and lifting, convenient installation.Described in the present embodiment, support column 1-4 and support beam 1-5 all use square steel tube, contact for face between square steel tube, easy to operate during welding, are connected firmly.
