Description
Technical Field
The utility model relates to a building stair construction technical field especially relates to a steel stair are with consolidating instrument.
Background
At present, during the construction of the stairs in the building, a scaffold is usually erected at a stair opening or a steel stair is used, so that a worker can construct on the scaffold or the steel stair. When the steel stair is used, the hoisting distance and the aluminum die installation distance are reserved, so that the width of the steel stair is 300 to 400mm smaller than the width of a stair hole of the construction structure, and the steel stair is high in height, so that the stair is prone to shaking when the steel stair walks on the steel stair, and potential safety hazards are generated. In order to make the steel stair difficult to rock, at present, the steel bar is welded on the steel stair and is jacked on a construction structure body, so that the rocking of the steel stair is reduced. However, reinforcing the steel stair by welding reinforcing steel bars can only be suitable for the construction of one building, when the steel stair is turned over to be used in other building constructions, the original reinforcing steel bars need to be removed, new reinforcing steel bars with proper lengths are welded, and the steel stair is very troublesome and time-consuming and labor-consuming. The steel stair welded with the reinforcing steel bars is easy to scrape and touch other objects in the operation process, and the reinforcing steel bars are directly abutted to a construction structural body to easily damage a building.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model aims to provide a reinforcing tool for steel stairs.
The utility model adopts the technical proposal that: the utility model provides a steel stair are with reinforcement instrument, is including bearing seat, sleeve, bolt, nut, picture peg and clamp plate, bear seat fixed mounting on steel stair, bear and be provided with the slot on the seat, telescopic one end is connected with the nut, the upper end fixed connection of the other end and picture peg, the lower extreme of picture peg inserts in the slot, the one end of bolt is worn to establish and is stretched into the sleeve after through the nut, the other end and clamp plate fixed connection, bolt and nut threaded connection.
Furthermore, an arc-shaped bearing groove for bearing the sleeve is arranged on the bearing seat.
Further, the sleeve is coaxially arranged with the nut.
Furthermore, both sides of the nut are fixedly connected with a connecting plate, and the connecting plate is fixedly connected with the sleeve.
Furthermore, the pressing plate is a square plate, the length of the pressing plate is 100 millimeters, the width of the pressing plate is 100 millimeters, and the thickness of the pressing plate is 4 millimeters.
Compared with the prior art, the utility model discloses following beneficial effect has: a steel stair are with reinforcement tool, install on steel stair, prevent effectively that steel stair from rocking, the utility model discloses easy installation, labour saving and time saving can have enough to meet the need the use, the suitability is wider.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic sectional view of the present invention;
fig. 3 is a schematic structural view of the sleeve and the bearing seat.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 3, a steel stair is with reinforcement instrument, including bearing seat 1, sleeve 2, bolt 3, nut 4, picture peg 5 and clamp plate 6, bearing seat 1 fixed mounting is provided with slot 101 on the steel stair, the one end and the nut 4 of sleeve 2 are connected, the upper end fixed connection of the other end and picture peg 5, and the lower extreme of picture peg 5 inserts in slot 101, the one end of bolt 3 is worn to establish and is stretched into sleeve 2 behind the nut 4, and the other end and clamp plate 6 fixed connection, bolt 3 and nut 4 threaded connection.
The bearing seat 1 is provided with an arc-shaped bearing groove 102 for bearing the sleeve 2.
The sleeve 2 is arranged coaxially with the nut 4.
Both sides of nut 4 all fixedly connected with a connecting plate 7, connecting plate 7 and sleeve 2 fixed connection. The nut 4 is through two connecting plates 7 and sleeve 2 fixed connection promptly, and such connected mode makes nut 4 position more stable, and life is longer, can be better carry on spacingly to the bolt.
The pressing plate 6 is a square plate, the length of the pressing plate 6 is 100 millimeters, the width of the pressing plate 6 is 100 millimeters, and the thickness of the pressing plate 6 is 4 millimeters. The pressing plate 6 is large in area, the pressing plate 6 presses the construction structure body, pressure intensity is small, and the construction structure body cannot be damaged.
The utility model discloses during the use, thereby change bolt 3 through rotatory bolt 3 and stretch out the length of sleeve 2 to make 6 tops of clamp plate tightly on the construction structure, picture peg 5 also tightly supports 1 inner wall of bearing seat in the top this moment, thereby prevent effectively that steel stair from rocking. The utility model discloses easily installation, labour saving and time saving saves the manual work.
Through the length difference that makes bolt 3 stretch out, thereby make the utility model discloses with the utility model discloses the suitability of the steel stair of installing is wider, can have enough to meet the need and be used for different construction building.
After the steel stair is used, the bolts 3 are rotated to enable the pressing plate 6 to be far away from the construction structure body, and then the inserting plate 5 is pulled out of the inserting groove 101. Because the bearing seat 1 is flat, other objects are not easy to be scraped during transportation.
The above embodiments are based on the technical solution of the present invention, and detailed implementation and specific operation processes are given, but the present invention is not limited to the above embodiments.
