Detailed description of the invention
Below in conjunction with accompanying drawing and concrete case study on implementation a kind of locking device fixing for railing of the present utility model done and further elaborate, but protection domain of the present utility model can not be limited with this.
See Fig. 1, Fig. 1 is the scheme of installation of a kind of locking device fixed for railing of the utility model.As can be seen from Figure 1, locking device of the present utility model includes column 1, clamp 3 and bolt 2 three parts.Clamp 3 includes grooved steel plate 31 and nut 32.As can be seen from Figure 2, Fig. 2 is clamp structure schematic diagram in a kind of locking device fixing for railing of the utility model to the structure of clamp 3.Fluting on grooved steel plate 31 is by the shaping formation of steel plate bending, and the fluting of grooved steel plate 31 is U-type groove, and the part of steel plate bending is two wing plates 312 forming U-type groove; Grooved steel plate 31 is provided with the installing hole 311 for interspersed bolt 2, column 1 is provided with 11 for interspersed bolt 2; Column 1 is connected by screw rod with clamp 3, and screw rod to be interspersed in the installing hole 311 on 11 on column 1 and grooved steel plate 31 and to be fixed by nut 32; The opening of the U-type groove on grooved steel plate 31 is towards column 1, and railing A is arranged on the position between U-type groove and column 1.By screwing bolts 2, clamp 3 is moved to column 1 direction, clamp 3 drives the railing A in U-type groove close towards column 1 direction, and then realizes railing A to be firmly locked between clamp 3 and column 1.
Nut 32 is fixedly welded on the position of installing hole 311 on grooved steel plate 31.First then fixed by nut 32 through installing hole 311 when bolt 2 is connected with clamp 3, add the compactness that bolt 2 is connected with grooved steel plate 31, ensure that clamp 3 can be good at locking railing A.And prevent because often dismounting causes the loss of nut 32.Nut 32 and U-type groove lay respectively at the both sides of grooved steel plate 31, ensure that nut 32 does not occupy the installing space of railing A in U-type groove.
Bolt 2 has enough length, makes bolt 2 through 11 on column 1, and be connected on clamp 3, can fix railing A securely after tightening.Require that the length of bolt 2 is greater than the diameter of column 1 and the thickness sum of the diameter of railing A, the thickness of grooved steel plate 31 and nut 32.
11 and the size of installing hole 311 and bolt 2 match, ensure that bolt 2 can either smoothly through 11 and installing hole 311, again can not because of 11 and the excessive screw rod that causes of installing hole 311 rock.
Two wing plates 312 on grooved steel plate 31 are arranged above and below along column 1, ensure the railing A of installation and can keep mutually vertical between column 1.The setting up and down of wing plate 312 can ensure that railing A can not slide up and down along on column 1 direction.
The degree of depth of U-type groove is less than the diameter of railing A, and when enabling fastening bolt 2, railing A directly contacts with column 1, and two of grooved steel plate 31 wing plates 312 do not reach column 1.If the U-type groove degree of depth is greater than railing A diameter, after two wing plates 312 of screwing bolts 2 time slot shape steel plate 31 contact, railing A can not be pressed on column 1 by clamp 3, can not realize fixing railing A.On grooved steel plate 31, the wing plate 312 of U-type groove both sides is stuck in the movement that railing A effectively can prevent railing A, is realized the installation and removal of railing A by the installation and removal of bolt 2.
Installing hole 311 on grooved steel plate 31 is positioned at the center of U-type groove, is namely positioned at two wing plate 312 centre positions, and two railing A are positioned at U-type groove and lay respectively at the both sides of screw rod.When screwing bolts 2, two railing A that can ensure to lay respectively in U-type groove bolt 2 both sides to be pressed on column 1 and stressed identical simultaneously.
Column 1 is arranged on the position near railing A, the making material of column 1 is the steel pipe that bearing capacity is stronger, column 1 is provided with the through hole of erection bolt 2, and as shown in Figure 3, Fig. 3 is the structural representation of a kind of locking device central post fixed for railing of the utility model.According to practical application need can be provided with on column 1 at least one 11, and set 11 height on column 1 are different.11 of proper height can be selected according to the height installing clamp 3, also on same column 1, multiple railing A can be installed differing heights.On column 1, the perforate of 11 can towards different directions according to the actual requirements.Such as, when needing the railing A fixing two mutual right-angled intersections, select orthogonal two 11 of perforate direction that clamp 3 is installed.
In the process that scaffold protective frame is set up, a kind of locking device installation steps in use of fixing for railing of the present utility model are as follows:
The first step: before setting up guard rail A, bolt 2 is first pierced into 11 on column 1 by scaffold building personnel;
Second step: connect clamp 3 and bolt 2, make the U-type groove opening of grooved steel plate 31 towards column 1, namely wing plate 312 direction is towards column 1, and this process is without the need to tightening bolt 2;
3rd step: column 1 is fixed on the region needing to set up guard rail A;
4th step: put into by railing A in the U-type groove of grooved steel plate 31, tights a bolt 2, completes railing A and fixes.
Locking device structure of the present utility model is simple, it is firm to lock and easy for installation, can prolonged and repeatedly use.What the utilization of the utility model device can greatly reduce scaffold guard rail sets up the time, improves production efficiency, and greatly reduces the proportion of goods damageds of column, decrease a large amount of material maintenance costs, have good application prospect.
