Abstract
The utility model discloses a fixing clamping member for steel tubes for edge guardrails. The fixing clamping member comprises cross-shaped fixing clamping member bodies made of phi53 steel tubes, threaded holes are formed in steel tubes around the fixing clamping member bodies, phi48 guardrail steel tubes are fixed through the fixing clamping member bodies made of the phi53 steel tubes and expansion screws, existing fasteners are replaced, the fixing clamping member cannot be damaged easily, and the repeated utilization rate is high; and short steel tubes can serve as cross rods and utilized. The fixing clamping member is quick in assembly, light, convenient to produce, simple to install and low in technical skill requirement.
Description
Technical field
The utility model relates to a kind of frontier defense guard rail rod steel pipe fixed fastener that faces.
Background technology
Along with China's rapid growth of economy, highrise building has also obtained development at a high speed, the highrise building of 20 multilayers and 30 multilayers has been practised sky now and has been seen and be used to, the building of 40 multilayers even 50 multilayers has also appearred in some area, and in the work progress of highrise building, safety and the programming that frontier defense protects engineering of facing of building plays crucial effects again.So for the pressure that satisfies construction party on the engineering safety protection purpose up to standard is very big, should also want salary earner payer expenses of labour to the rental charge that leasing company pays wholesale.So, accomplish to protect and up to standardly not only waste money but also incur loss through delay the duration according to traditional fixedly assembly mode.
Facing at present that frontier defense protects in construction is heavy especially of sport, be control safety key factor up to standard, to face the protective materials on limit mainly be to assemble with fastener with steel pipe to set up to floor in the past: vertical rod is embedded in the floor to be connected with cross bar by fastener and places metope or cylinder inside to play the effect of protection.Each Lin Bianlou two vertical rods of all need standing during routine is set up, could be connected by fastener with cross bar like this, and the vertical rod height must not be lower than 1.2 meters, and face the long position guard rail in limit and need per two meters and vertical rod is set as support, often short steel pipe then can't be used for guard rail in construction.
The utility model content
The technical problems to be solved in the utility model provides a kind of frontier defense guard rail rod steel pipe fixed fastener that faces.
The technical solution of the utility model is: a kind of frontier defense guard rail rod steel pipe fixed fastener that faces, comprise the cross fixed fastener of being made by Φ 53 steel pipes, and the steel pipe around the fixed fastener is provided with screwed hole.
The length of described fixed fastener is 17-20 centimetre.
Described screwed hole is 2-3 centimetre to the distance of steel tube end part.
Described outer wall of steel pipe is provided with protective paint layer.
The beneficial effects of the utility model are: the guard rail steel pipe of Φ 48 fixed with setscrew by the fixed fastener of being made by Φ 53 steel pipes, existing fastener is replaced, and fixed fastener are not fragile, and the recycling rate of waterused height; Cross bar can adopt short steel pipe, short steel pipes can also be utilized, and the utility model is assembled fast, and is light; Easy to make, to install simple and easyly, it is low that technical capability requires.
Description of drawings
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 uses schematic diagram for the utility model.
The specific embodiment
A kind of frontier defense guard rail rod steel pipe fixed fastener that faces; comprise the cross fixed fastener of being made by Φ 53 steel pipes 24; steel pipe around the fixed fastener is provided with screwed hole 3; the length of fixed fastener is 18 centimetres; described screwed hole is 3 centimetres to the distance of steel tube end part, and described outer wall of steel pipe is provided with protective paint layer.
Processing technology: with Φ 53 wall thickness 3mm(internal diameter 50mm) steel pipe is processed into cross specification shape, and boring, and forms screw thread at hole wall; And join one piece of bolt at screwed hole, and the fixed fastener mopping after the processing is handled.This fixed fastener can be processed at the scene, also can process in factory, and is easy to process, and fixed fastener is not fragile, the recycling rate of waterused height.
Construction technology: guard rail Φ 48 steel pipes 1 are inserted in the fixed fastener, and bolt is tightened the fixed protection railing get final product.
Economic and Efficiency Analysis: adopt the common steel tube fixed fastener to protect required expense: face limit (less than two meters) by one and calculate for the unit: two cross bars of needs, two vertical rods, fixed fastener needs 6.
According to the actual rental charge in job site, 0.008 yuan of/sky of fastener.
The every month fixed fastener lease expenses in a hole is: * 0.008(rental charge every day 6(fastener number)) * 30(days)=1.44 yuan (every month rental charge)
And adopt novel guard rail fixed fastener only to need disposable input, no longer produce other fees: 1 yuan of each fixed fastener, 6 at each hole needs 1*6=6 unit.
Calculated in 1 year as pressing, 1.44*12=17.28 unit, fixed fastener only need drop into 6 yuan, and expense can be reduced in annual each hole: 17.28-6=11.28 unit.
