The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.

As shown in Figure 1, the utility model provides a kind of guard rail, is used for the various unlimited edge in the construction operation place of engineering construction work progress is carried out security protection.Guard rail is made up of the support protective unit more than two groups, and every pack support protective unit comprises vertical rod 10 and the cross bars 20 that laterally are connected with vertical rod 10; Be provided with connector 30 between the support protective unit, connector 30 is connected with the cross bar 20 of adjacent supports protective unit with fixing two adjacent pack support protective units.When the assembly and disassembly of support protective unit, be connected and fixed two adjacent pack support protective units with connector 30, need not use other fasteners during installing/dismounting, installation and removal are more convenient and easy, and can not cause damage to the support protective unit after the dismounting, the parts after the dismounting can repeat turnover and use.

In conjunction with referring to Fig. 2, the vertical rod 10 of the guard rail of this preferred embodiment is provided with for the connecting hole 12 that connects cross bar 20, when forming guard rail, cross bar 20 laterally is connected with vertical rod 10 by the connecting hole 12 that passes through in the vertical rod 10, thereby forms a pack support protective unit.Particularly, the number of the connecting hole 12 in the vertical rod 10 is two, correspondingly, the quantity of the cross bar 20 that laterally is connected with vertical rod 10 in each support protective unit is two, be that every pack support protective unit is made up of a vertical rod 10 and two cross bars 20, make guard rail in simple in structure, can satisfy the demand of security protection.

As shown in Figure 3, in this preferred embodiment, the lower end of vertical rod 10 is connected with holder 11, and holder 11 is provided with first bolt hole 15, and the expansion bolt that sets on ground is fixed in ground by first bolt hole 15 on the holder 11 with vertical rod 10 and holder 11.Use expansion bolt fixedly vertical rod 10 and holder 11, need or not to carry out welding operation at the ground embedded iron parts, feasiblely set up time saving and energy savingly, reduced cost; Further, vertical rod 10 is one-body molded with holder 11, and is convenient when making support; Particularly, dismounting vertical rod 10 only needs during with holder 11 expansion bolt severed and get final product, only damages expansion bolt, can not cause loss to vertical rod 10 and holder 11, and vertical rod 10 and the holder of pulling down 11 can repeat the turnover use.

As Fig. 4, shown in Figure 5, in this preferred embodiment, two ends of the cross bar 20 of support protective unit are provided with second bolt hole 25, and connector 30 is for being provided with the sleeve pipe of the 3rd bolt hole 35, cross bar 20 and connector 30 by second bolt hole 25 and the 3rd bolt hole 35 cooperate be connected and fixed.When the cross bar 20 of support protective unit is connected with connector 30 bolts.Only need earlier connector 30 to be placed in adjacent two pack support protective unit cross bars, 20 interconnective ends, with bolt connector 30 is connected with the cross bar 20 of support protective unit then, only need pull down the separable cross bar 20 of connecting bolt and connector 30, simple to operate saving trouble during dismounting.

In this preferred embodiment, in order to make the sleeve pipe of connector 30 to be enclosed within smoothly on the cross bar 20, the internal diameter that the sleeve pipe of connector 30 is set is greater than or equal to the external diameter of cross bar 20; In the practical application, when the external diameter of connector 30 equated substantially with cross bar 20 internal diameters, effect was better.Preferably, in this preferred embodiment, second bolt hole 25 is arranged between two end homogeneous phases of cross bar 20, the 3rd bolt hole 35 is being arranged between homogeneous phase on the connector 30, can regulate the permanent position of connecting bolt on cross bar 20 ends and connector 30 according to the place needs, and then can piecewise uniform ground adjust the connection length of guard rail, and make that the application of guard rail is more flexible, strengthened practicality greatly.

To sum up, guard rail of the present utility model, cross bar 20 laterally is connected with vertical rod 10 by the connecting hole 13 in the vertical rod 10, thereby forms a pack support protective unit; The cross bar 20 of two adjacent pack support protective units is connected and fixed by connector, and is simple to operation.Vertical rod 10 lower ends are connected with holder 11, and first bolt hole 15 is set on the holder 11, finish fixing to vertical rod 10 and holder 11 by expansion bolt, good fixing effect, and also easy to implement; In addition, the cross bar 20 of each pack support protective unit of guard rail evenly respectively is provided with second bolt hole 25, evenly respectively be provided with the 3rd bolt hole 35 on the connector 30, during practical application, thereby can regulate the connection length of the position adjusting guard rail of connecting bolt according to the needs of construction plant, make that the utility model scope of application is wider.During the utility model dismounting, only need untie the bolt that connects cross bar 20 and connector 30, the expansion bolt of severing on the holder 12 gets final product, and the dismounting operation simply and not can cause damage to guard rail, the parts that disassemble can repeat turnover and use, and have improved the utilization ratio of guard rail.

The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
