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; gaskets are arranged on joints between the ladder sections and the inner sides of the straight ladder poles; 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, the D-shaped pipes are used as the ladder sections, and the gaskets are arranged on joints of the ladder sections and the inner sides of the straight ladder poles, so that the ladder is good in load-bearing and steadiness while functions of the ladder are realized, the ladder can be firmer and more durable, and friction noise causing unsafe psychological influence to a person, which is generated when the joints of the ladder sections and the ladder poles can be prevented when the straight ladder is used.
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, directly is squeezed on the side of terraced bar by D shape is managed two ends, and the terraced bar of this ladder is owing to adopting the flute profile material to make, bearing is poor, and is not too firm; In addition, can make in use section of ladder produce relative sliding and then send friction noise in terraced bar junction and terraced bar, affect to a certain extent people's safe handling, can cause a kind of unsafe psychological impact to the people.
The utility model content
The vertical ladder that provides a kind of construction industry to use is provided the purpose of this utility model, its bearing and steadiness are all good, and can not make section of ladder produce relative sliding in terraced bar junction and terraced bar when using, and then avoid sending because of friction the noise that causes a kind of unsafe psychological impact to the people.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is as follows:
The vertical ladder that a kind of construction industry is used, comprise 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, described straight line ladder bar is box section, and described section of ladder is D shape pipe, is provided with pad at described section of ladder and junction, described straight line ladder bar inboard.
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, and be provided with pad at described section of ladder and junction, described straight line ladder bar inboard, in the function that has realized ladder, and make the load-bearing of ladder and steadiness good, make ladder more durable, and section of ladder can not occur in use and the friction noise that causes a kind of unsafe psychological impact to the people is sent in terraced bar junction because of slip.
Description of drawings
Figure 1 shows that the main TV structure schematic diagram of the vertical ladder that construction industry that the utility model embodiment provides is used;
Figure 2 shows that the structural representation of the side-looking of the vertical ladder that construction industry that the utility model embodiment provides is used;
Figure 3 shows that the schematic diagram of the pad that the utility model embodiment provides;
In figure: 1, terraced bar, 2, section of ladder, 3, pad.
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.
Shown in Fig. 1 ~ 3, the vertical ladder structure that the construction industry that the figure shows the utility model embodiment provides is used.For convenience of explanation, only show the part relevant with the utility model embodiment.
The vertical ladder that a kind of construction industry is used, comprise the two straight line ladder bars 1 that be arranged in parallel and the parallel some section of ladders 2 that are located at 1, described two straight line ladder bar, described straight line ladder bar 1 is box section, described section of ladder 2 is D shape pipe, is provided with pad 3 in described section of ladder 2 and described straight line ladder bar 1 inboard junction.
More excellent, described box section is rectangular tube.
The utility model is by adopting box section as terraced bar, with D shape pipe as section of ladder, and be provided with pad at described section of ladder and junction, described straight line ladder bar inboard, in the function that has realized ladder, and make the load-bearing of ladder and steadiness good, make ladder more durable, and section of ladder can not occur in use and the friction noise that causes a kind of unsafe psychological impact to the people is sent in terraced bar junction because of slip.
More excellent, the cross sectional shape of the shape of described pad 3 and described section of ladder 2 adapts
More excellent, the two ends of described section of ladder 2 link together by turnup structure and described straight line ladder bar 1.
Because the two ends of described D shape pipe are connected by turnup structure and described straight line ladder bar, 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 1 and section of ladder 2 are aluminum alloy material and make.Described pad 3 is made for aluminum alloy material.
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.
