Description
Technical field
The utility model relates to a kind of base device of security protection guardrail, espespecially a kind of base device for work progress steel work security protection guardrail.
Background technology
In building operations, due to steel building have lightweight, intensity is high, anti-seismic performance good, can reasonable Arrangement functional areas between, the construction period is short, recycle and be worth high and comprehensive cost is low, obtains in recent years general application.
At present at the construction field (site), as shown in Figure 1, the setting that intersects vertically of many horizontal long steel pipes 10 and many vertical long steel pipes 20, fixes by anchor ear or thicker wire colligation at infall mutually the steel structure protective guardrail of building, and has formed steel structure protective guardrail.This protection guardrail is arranged on the limit of facing of building, constructor is played to the effect of security protection.When this steel structure protective guardrail is installed, vertically long steel pipe 20 bottoms are directly welded on floor base plate 30, during to floor base plate 30 concreting, the vertical long steel pipe 20 of part is embedded in concrete, in the time of dismounting steel structure protective guardrail, vertical long steel pipe 20 can only be cut off to dismounting, its length shortens like this, is unfavorable for that the turnover in later stage is used.Because vertical long steel pipe 20 is directly welded on floor base plate 30, in the time that needs are set up steel structure protective guardrail again, it is not easy to remove again, and flexibility is poor.
Utility model content
The purpose of this utility model is to overcome the defect of prior art, and a kind of base device of steel work security protection guardrail is provided, and makes steel structure protective guardrail easy accessibility, improves the turnover repeat usage of steel pipe.
The technical scheme that realizes above-mentioned purpose is:
The base device of the utility model steel work security protection guardrail, described steel work security protection guardrail is mainly intersected vertically and is formed by connecting by many horizontal long steel pipes and many vertical long steel pipes, and described base device comprises:
One short steel pipes, offers a through hole on the sidewall of described short steel pipes, be welded with a nut on described through hole; The internal diameter of described short steel pipes is greater than the external diameter of described vertical long steel pipe; Described vertical long steel pipe is inserted in described short steel pipes;
One adapts to the screw rod of described nut, and described screw rod is screwed together in described nut, and wears described through hole and push against on the outer wall of described vertical long steel pipe, thereby orders about described vertical long steel pipe fastening on the inwall of described short steel pipes.
Adopt the base of thick short steel pipes as steel work security protection guardrail, be welded on the base plate of floor, vertically long steel pipe is inserted in short steel pipes, by the fastening vertical long steel pipe of the screw rod on short steel pipes, has guaranteed the steadiness of steel structure protective guardrail.When dismounting, only screw rod need be unscrewed, extract vertical long steel pipe, it is all convenient to install with dismounting.Compared to existing technology, cut off dismounting, the utility model has guaranteed the complete of long steel pipe, can repeat turnover and use.
Improvement of the present utility model is: described long steel pipe is Φ 48 steel pipes.
Improvement of the present utility model is: described short steel pipes is Φ 60 steel pipes.

Fig. 2 is the perspective view of the base device of the utility model steel work security protection guardrail;
Fig. 3 is that the base device of the utility model steel work security protection guardrail is along the sectional view of horizontal center line axis downward direction;
Fig. 4 be the utility model steel work security protection guardrail base device use time perspective view.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Shown in Figure 2, be the perspective view of the base device of the utility model steel work security protection guardrail.This base device comprises a short steel pipes 40, offers a through hole 401 on the sidewall of this short steel pipes 40, is welded with a nut 402 on through hole 401.Shown in Fig. 3, the internal diameter of this short steel pipes 40 is greater than the external diameter of the vertical long steel pipe 20 of steel work security protection guardrail, and vertically long steel pipe 20 can be inserted in short steel pipes 40.
This base device also comprises that one adapts to the screw rod 403 of nut 402, the external thread spiro fastening of screw rod 403 is in the internal thread of nut 402, screw rod 403 wears through hole 401 and pushes against on the vertical long steel pipe 20 in short steel pipes 40, continue to tighten screw rod 403, be anchored on the inwall of short steel pipes 40 thereby order about vertical long steel pipe 20, realize the fastening of vertical long steel pipe 20.
Refer to shown in Fig. 4, this device in use, is directly welded on short steel pipes 40 on floor base plate 30, or is welded on the girder steel of steel pipe.After short steel pipes 40 has welded, vertically long steel pipe 20 is inserted in short steel pipes 40, by tightening screw rod 403, vertically long steel pipe 20 is fixing, after many vertical long steel pipes 20 fix, connect laterally long steel pipe 10 according to prior design, by anchor ear or thicker wire etc. laterally long steel pipe 10 be vertically fixed on vertical long steel pipe 20, the security protection guardrail of steel work has just been set up like this.
As a preferred embodiment of the present utility model, at the construction field (site), the short steel pipes in the utility model base device is selected Φ 60 steel pipes, and laterally long steel pipe 10 and vertical long steel pipe 20 are selected Φ 48 steel pipes.Burrow and form a through hole 401 at the sidepiece of Φ 60 steel pipes, on through hole 401, weld a nut 402, screw togather the base device that a screw rod 403 has just formed steel work security protection guardrail.Then Φ 48 steel pipes are inserted in Φ 60 steel pipes, tighten screw rod 403 by Φ 48 steel pipe fastenings in Φ 60 steel pipes, then connect the security protection guardrail that horizontal long steel pipe 10 has just formed steel work.The utlity model has the features such as simple, easy to use of making.
When on floor base plate 30 when concreting, short steel pipes 40 is cast in floor concrete, its length is greater than the height of concreting, so having sub-fraction, exposes on concrete surface short steel pipes 40, while removing steel work security protection guardrail, only screw rod need be unscrewed, extract vertical long steel pipe 20.The long steel pipe that can make like this to form steel work security protection guardrail is intact, conveniently repeats turnover and uses, cost-saving.Adopt this base device, make the installation and removal of steel work security protection guardrail all convenient, there is practicality.
Below embodiment has been described in detail the utility model by reference to the accompanying drawings, and those skilled in the art can make many variations example to the utility model according to the above description.Thereby some details in embodiment should not form restriction of the present utility model, the utility model by the scope defining using appended claims as protection domain of the present utility model.
