Abstract
The utility model belongs to the technical field of ladders, and in particular discloses a straight ladder for the construction industry. The straight ladder for the construction industry comprises two parallel arranged straight ladder poles and a plurality of ladder sections which are arranged between the two straight ladder poles in parallel, wherein the straight ladder poles are square pipes, and the ladder sections are D-shaped pipes; two ends of each ladder section are connected with the straight ladder poles through a flange structure; and the straight ladder poles and the ladder are made of an aluminum alloy material. According to the straight ladder, the square pipes are used as the ladder poles, and the D-shaped pipes are used as the ladder sections, so that the ladder is good in load-bearing and steadiness while functions of the ladder are realized, and the ladder can be firmer and more durable.
Description
Technical field
The utility model relates to a kind of ladder, specifically the vertical ladder used of a kind of construction industry.
Background technology
At present, the vertical ladder that building trade is used, general is all to adopt the two straight line ladder bars that be arranged in parallel and the parallel some section of ladders that are located between described two straight line ladder bars to form, the section of ladder of some vertical ladders also adopts D shape pipe as section of ladder, the terraced bar of this ladder generally adopts the flute profile material as terraced bar, the terraced bar of this ladder is owing to adopting the flute profile material to make, and bearing is poor, and is not too firm.
The utility model content
The purpose of this utility model is to provide all vertical ladders of using of good construction industry of a kind of bearing and steadiness.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is as follows:
A kind of vertical ladder comprises the two straight line ladder bars that be arranged in parallel and the parallel some section of ladders that are located between described two straight line ladder bars, and described straight line ladder bar is box section, and described section of ladder is D shape pipe.
The two ends of described section of ladder link together by turnup structure and described straight line ladder bar.
Described straight line ladder bar and section of ladder are aluminum alloy material and make.
The utility model is by adopting box section as terraced bar, with D shape pipe as section of ladder, in the function that has realized ladder, and load-bearing and steadiness good, make ladder more durable.
Description of drawings
Figure 1 shows that the main TV structure schematic diagram of the vertical ladder that the utility model embodiment provides;
Figure 2 shows that the side-looking structural representation of the vertical ladder that the utility model embodiment provides;
In figure: 1, terraced bar, 2, section of ladder.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is further elaborated.
Referring to Fig. 1, the figure shows the structure of the vertical ladder that the utility model embodiment provides.For convenience of explanation, only show the part relevant with the utility model embodiment.
A kind of vertical ladder comprises the two straight line ladder bars that be arranged in parallel and the parallel some section of ladders that are located between described two straight line ladder bars, and described straight line ladder bar is box section, and described section of ladder is D shape pipe.
The utility model is by adopting box section as terraced bar, with D shape pipe as section of ladder, in the function that has realized ladder, and load-bearing and steadiness good, make ladder more durable.
Further, the two ends of described section of ladder link together by turnup structure and described straight line ladder bar.
The two ends of described D shape pipe are connected with described straight line ladder bar by turnup structure, make connection more firm, and comparatively simple in manufacturing process, after directly the installing hole of the correspondence on described terraced bar being passed at the two ends of described D shape pipe, the D shape termination flange that will stretch out with instrument is pressed on described terraced bar lateral surface and gets final product.
Further, described straight line ladder bar and section of ladder are aluminum alloy material and make.
The utility model has not only strengthened the steadiness of ladder, and has made ladder described in the utility model more light by adopting aluminum alloy material to make, and conveniently moves.
The above is only preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
