Description
Technical Field
The utility model relates to a steel construction board house stair structure.
Background
The light steel box house (also called steel structure board house) is convenient for transportation, transfer and reuse, so the light steel box house is very popular as a temporary house for field, disaster relief and the like. In order to facilitate disassembly and quick assembly, the base, the wall plate and the roof of the steel structure board house adopt riveting structures (bolt connection structures).
Most of the existing high-grade steel structure board houses have a multilayer structure with built-in stairs, namely, the steel structure board houses adopt the structural form of light steel villas, and the stairs are arranged inside the houses. Because the structural feature place of steel construction board house must adopt steel stair, the bottom and the bottom of stair all are equipped with flat straight plate, install stair between two-storey building about through flat straight plate and the bolt that passes flat straight plate, and the shortcoming of this kind of structure lies in, and the straight plate that stretches out and the bolt of connection on flat straight plate must be higher than ground, not only beautifully, appears hurting people's problems such as colliding with easily moreover, therefore greatly reduced the quality of steel construction board house.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a steel construction board house stair structure, it can avoid appearing connecting position and expose the problem in the outside, avoids appearing the injury people problem such as colliding with to improve the quality in steel construction board house.
In order to solve the technical problem, the utility model provides a steel construction board house stair structure, its two terraced guardrails including relative setting and the multistage footboard of connection between two terraced guardrails, its structural feature is: the lower part of the stair guardrail is fixedly connected with an upper connecting plate which extends downwards and is attached to the upper part vertical plate of the pedal at the uppermost part, the lower connecting plate and the upper connecting plate are both provided with bolt connecting holes, the inner surface of the lower part vertical plate of the pedal at the lowermost part is connected with a supporting upright post, and the lower connecting plate is connected with the lower part vertical plate and the supporting upright post through bolts.
The lower end of the upper connecting plate is lower than the bottommost part of the top of the stair guardrail, and the lower part of the upper connecting plate is connected with an upper connecting cross beam capable of being connected with a top building.
The stair guardrail comprises guardrail rods which are arranged oppositely from top to bottom, and reinforcing rib rods which are arranged in a bent manner are connected between the two guardrail rods.
After adopting above-mentioned structure, owing to set up the upper junction plate and the lower junction plate of above-mentioned structure, when making this stair of installation, wear to adorn horizontal bolt and all can realize the installation, the convex part appears in subaerial appearance of lower floor's building and superstructure no longer, has effectively avoided appearing hurting one's problems such as colliding with, has guaranteed the level and smooth degree on ground, has improved the performance of steel construction board house.
To sum up, the utility model has the advantages of use safe and reliable and the stair installation is firm effect.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments:
FIG. 1 is a schematic structural diagram of a stair structure of a steel-structure board house in the prior art;
FIG. 2 is a schematic top view of the structure of FIG. 1;
fig. 3 is a schematic structural diagram of an embodiment of the present invention;
FIG. 4 is a schematic top view of FIG. 3
FIG. 5 is a schematic structural view taken along line A-A in FIG. 3;
FIG. 6 is a schematic view of the connection of adjacent pallets.
Detailed Description
As shown in fig. 1 and 2, the stair structure of the steel structure board house in the prior art is provided in the drawing, the stair structure comprises a guardrail and a pedal, the upper part and the lower part of the pedal or the guardrail are connected with an extension plate 10, the extension plate 10 is provided with bolt holes, and the connecting plate is connected to the ground of an upper-layer building and a lower-layer building through bolts penetrating through the bolt holes, so that the part provided with the connecting plate and the heads of the bolts are higher than the ground, the collision problem is easy to occur, people are easy to trip, the injury accident is caused, and the quality of the steel structure board house is greatly reduced while the accident is easy to occur.
Referring to fig. 3 to 6, the present invention provides an embodiment of a stair structure of a steel-structure plank house, which includes two opposite stair railings 1 and a multi-level tread 2 connected between the two stair railings, in this embodiment, the stair railing 1 includes upper and lower guardrail rods opposite to each other, reinforcing bars arranged in a bending manner are connected between the two guardrail rods, the tread 2 is composed of a lower vertical plate, a patterned plate and an upper vertical plate, the bottom end of the lower vertical plate of the lowest tread is attached to the ground, in the adjacent two-level tread, the upper vertical plate of the lower tread is fixedly connected to the lower vertical plate of the upper tread, thereby forming a continuous multi-level tread, the lower portion of the stair railing 1 is fixedly connected to a lower connecting plate 3 extending downward and attached to the lower vertical plate of the lowest tread, the lower connecting plate 3 is provided with a bolt connecting hole, the inner surface of the lower vertical plate of the lowest pedal is connected with a support upright post 5, the lower connecting plate is connected with the lower vertical plate and the support upright post through bolts, and the structure basically needs the lower connecting plate to be connected with the bottom surface of a lower-layer building, so that the lower part of the whole stair only plays the role of a support leg.
Referring to fig. 3 to 6, an upper connecting plate 4 extending downwards is connected to the upper portion of the stair guardrail 1 and abuts against an upper vertical plate of an uppermost step, each upper connecting plate 4 has a bolt connecting hole, when a top beam is arranged at a position of a stair of an upper building, the upper connecting plate 4 can be directly connected to the top beam through a connecting bolt passing through the bolt hole, the lower end portion of the upper connecting plate 4 is lower than the bottommost portion of the top of the stair guardrail, an upper connecting cross beam 6 capable of being connected with the top building is connected to the lower portion of the upper connecting plate 4, when the stair is not provided with the top beam, the upper connecting cross beam 6 is connected to the top beam of the upper building, and the length and the extending condition of the upper connecting cross beam 6 can be determined according to the situation on site, so as to ensure the connection between the upper.
The utility model discloses can also have other embodiments, other technical scheme that form in the record of claim no longer carry out the repeated description one by one, the utility model discloses do not receive the restriction of above-mentioned embodiment, based on the equivalent change and the part replacement of above-mentioned embodiment are all in the utility model discloses a protection within range.
