Abstract
The utility model relates to a combined stair beam, which is formed by superposing and fixedly connecting at least two slices of oblong hard plates, and a slot which can be used for being embedded and fixing a stair rail is formed between the two slices of oblong hard plates which are formed into the stair beam. The stair beam can be a multi-section type structure, a middle connecting plate is clamped between the forked tail ends of section type hard plates, and the middle connecting plate is extended outward for a part which is used for connecting the forked tail end of the adjacent section type hard plate and the sharp corner end of the other section. A stair which is formed by combining the stair beam, a ladder plate and a platform is concise, lively, and shapely configuration from a whole body; in addition, the stair beam of the utility model can realize industrialization volume production, can be matched by adopting different length sections to satisfy the requirements of customers according to the requirements of different customers, and relieves the process steps that the existing stair needs to be made after measured.
Description
Technical field
The utility model relates to a kind of stair stringer, especially a kind of stair stringer of being made by hard material such as steel, alloy or plastic-steel.
Prior art
Stair are made up of gangboard, railing, river, hurdle and stair stringer etc., the stair stringer in past is generally with monoblock steel plate, alloy sheets or other hard material, process through boring, cutting etc., old money twin beams stair stringer generally is a single piece, during manufacturing, need be customized according to the real size in client house, the production cycle is long, cost is higher relatively, and can not organize production in enormous quantities.Moreover the size of " single piece " beam is long overweight, is unsuitable for remote vanning transportation, and the freight height; After old money stair stringer and gangboard, railing, the aggregate erection of river, hurdle, its structure is numerous and diverse, and cost promptly not attractive in appearance is high again.
Technical scheme
The technical problem that the utility model solves is to overcome above-mentioned shortcoming, and a kind of modular stairway beam is provided, and this stair stringer has simple in structure, convenient transportation, the characteristics of the whole stair brevity and lucidity in assembling back; This modular stairway can also standardization or industrialized mass production.
The technical solution of the utility model is: design a kind of modular stairway beam, it comprises at least by two superimposed affixed forming of rectangle hard plate, forms the groove that can be used for embedding river, stair hurdle between two rectangle hard plates behind the closed assembly.
This hard plate can be more piece segmentation hard plate, also has the middle connecting plate of a chip size less than the segmentation hard plate between every sectional type hard plate, and adjavant secional hard plate connects by middle connecting plate.
One end of above-mentioned segmentation hard plate is a dovetail, the other end is the wedge angle with the swallowtail shape complementation, middle connecting plate is clipped between segmentation hard plate dovetail one end, and a protruding part, and the coattail end of adjacent segmentation hard plate is connected by middle connecting plate with the closed angle end of another section.
Inwall at groove can have valve rubber.Earth terminal at stair stringer can have the ground connector; In the top upper connector can be arranged.
The utility model has been owing to adopted by two superimposed affixed forming of rectangle hard plate, forms the structure of the groove that can be used for embedding river, stair hurdle between two rectangle hard plates behind the closed assembly, and such stair stringer is seen brevity and lucidity on the whole.
In addition, stair stringer adopts the structure of joining by dovetail sheet and intermediate plate between multisection type and two adjacent segment, so just can realize industrialized mass production, select for use the collocation of different length section to satisfy requirement of client according to different clients' needs again, remove the operation of manufacturing after the first measurement from.
Description of drawings
Fig. 1: the modular stairway girder construction schematic diagram that the utility model is made of two whole slabs;
Fig. 2: the utility model is the decomposing schematic representation of segmented stair stringer;
Fig. 3: for Fig. 2 assembles staircase structure schematic diagram behind gangboard and the platform.
Embodiment
See also Fig. 1, a kind of modular stairway beam, it comprises by two length of a film square plates 1,11 are superimposed and forming by screw together, formed the groove 12 that can be used for embedding river, sheet glass hurdle 5 (see figure 3)s between the two length of a film square plates 1,11 after the installation, the valve rubber (not shown) can have been arranged at the inwall of groove 12.
Referring to Fig. 2, steel plate 1,11 shown in Figure 1 can be made more piece segmentation steel plate 2,21, segmentation steel plate 2,21 is that an end is a dovetail 23, the other end is the wedge angle 24 with dovetail 23 shape complementarities, between every sectional type steel plate 2,21, also have the steel middle connecting plate 22 of a chip size less than segmentation steel plate 2,21, middle connecting plate 22 is clipped between segmentation steel plate 2,21 dovetails 23 ends, and a protruding part, the coattail end of adjacent segmentation steel plate is connected by middle connecting plate 22 with the closed angle end of another section; Form the groove 12 that can be used for embedding river, sheet glass stair hurdle 5 (see figure 3)s between the segmentation steel plate 2,21 after the connection.Certainly, except that available dovetail type connected, also tack connected or connects with other shape for neat mouthful between the adjacent segmentation steel plate 2,21 of homonymy.Middle connecting plate 22 also can be clipped between segmentation steel plate 2,21 wedge angles 24 ends except can being clipped between segmentation steel plate 2,21 dovetails 23 ends.For conveniently seeing the structure of stair stringer clearly, the hypomere with the segmentation beam among the figure partly amplifies.
Fig. 3 is the stair that are assembled into stair stringer shown in Figure 2, and it also comprises gangboard 6, platform 8 and river, hurdle 5; River, flat glass hurdle 5 is embedded in the clip slot 12; Intermediate connector 7 is combined upper and lower bench of stair and landing beam 9, forms complete stair; One of gangboard 6 terminates on the stair stringer, and a side joint of platform 8 is on landing beam 9, and gangboard 6 other ends and platform 8 opposite sides can directly be fixed on the metope or join with other stair stringer, form twin-spar construction.Earth terminal in the bench of going downstairs has ground connector 3; Can there be upper connector 4 upper end at stair stringer.
Can find out clearly that from Fig. 3 the stair after the installation see that on the whole succinctly attractive in appearance, whole structure is good.
