The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Shown in Fig. 1-8.
The interim guard rail of a kind of assembly type stair, it is mainly lacked one turning column 1 than number of floor levels by quantity, column 2 that bottom and top layer are installed and adjustable armrest railing 3 are formed, column 2 is fixed on bottom and the top stair ground (as Fig. 8) by expansion bolt, turning column 1 is fixed on except that on the stair ground of bottom and top layer (as Fig. 7) by expansion bolt, one end of the adjustable armrest railing 3 of bottom and top layer links to each other with turning column 1 by connecting bolt, the other end also links to each other with column 2 by connecting bolt, and the two ends of the adjustable armrest railing 3 except that top layer and bottom link to each other with corresponding turning column 1 by connecting bolt respectively.As shown in Figure 1.Turning of the present invention column 1 is by left column 101, right column 102, connect cross bar 103 and elongated base plate 104 compositions, as Fig. 2, shown in 3, thereby elongated base plate 104 is provided with and installs expansion bolt elongated base plate is fixed on the ground through hole of stair, left column 101 and right column 102 are welded on the elongated base plate 104, connect to form doorframe shape structure by connecting cross bar 103 between left column 101 and the right column 102, upper end and/or place, centre position at left column 101 and right column 102 are provided with the brace 105 that links to each other with adjustable armrest railing 3, thereby brace 105 is provided with for the through hole of connecting bolt by adjustable armrest railing 3 is linked to each other with turning column 1.Column 2 of the present invention comprises cylinder 201 and short bottom plate 202, and cylinder 201 is welded on the short bottom plate 202, and expansion bolt is fixed on the ground through hole of stair by making short bottom plate thereby short bottom plate 202 is provided with confession; Upper end and/or middle part at cylinder 201 are connected with brace 203, thereby brace 203 is provided with for the through hole of connecting bolt by realizing linking to each other with adjustable armrest railing 3, shown in Fig. 4,5.Adjustable armrest railing 3 of the present invention is by the tubulose body of rod 301, fixedly connected 302, activity intubate 303 and flexibly connect sheet 304 and form, as shown in Figure 6, described fixedly connected 302 end with the tubulose body of rod 301 is weldingly connected, flexibly connect an end of sheet 304 and an end of activity intubate 303 and be weldingly connected, activity intubate 303 is inserted in the other end of the tubulose body of rod 301; Described fixedly connected 302 and flexibly connect and to be equipped with the through hole that passes through for connecting bolt on the sheet 304, and be arranged with the anti-interference structure 305 that connects, as symmetrically arranged chamfering or arc structure.In addition, fixedly connected 302 also can be weldingly fixed on earlier fixedly on the intubate 306 when specifically implementing, and fixedly intubate 306 is fixed by welding in the tubulose body of rod 301 again.
In addition, the intubate at the two ends of adjustable armrest railing 3 also can be designed to be movable structure when specifically implementing, and at this moment, only needs to install dog screw additional on the tubulose body of rod 301 and chute gets final product.
In addition, can the adjustable hand rail of one deck be set according to height of armrests when specifically implementing, also can design two layers or more adjustable hand rail, only need the burn-on brace of respective numbers of column and column corresponding position, turning to get final product.
Using method of the present invention is:
With expansion bolt column and turning column are fixed on the stair ground earlier, shown in Fig. 7,8, then with fixedly connected 302 of the tubulose body of rod 301 1 ends with column or turning column on corresponding brace link to each other, then activity intubate 303 is inserted in the pipe support, the position of adjusting activity intubate 303 in the tubulose body of rod 301 makes to flexibly connect sheet 304 and corresponding column or continuous the getting final product of the usefulness of the brace on the column of turning connection breechblock.During dismounting, unclamp the connecting bolt that connects the tubulose body of rod 301 earlier, take off the tubulose body of rod 301, unclamping column then can be connected base plate with the turning column with column with expansion bolt nut on the column of turning and take out from ground, only stay the expansion breechblock on stair ground, the normal construction that can make expansion bolt not influence balustrade by the method for welding or hammering gets final product, and the column of pulling down, turning column and adjustable armrest railing 3 can be transported to next building site to be continued to use.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
