How much is the stair wall handrail K7 type 30 2 stainless steel pipe on the market

Now stainless steel handrails, the general surface tube is made of millimeter thickness, and the small tube is millimeter. The thickness of the 25-sided pipe of the window guard is in, and the thickness of the round pipe of 19 is generally used in millimeters. (19 round flower tubes, that is, millimeters with patterns.) The pattern pipe is not thick, don't listen to the merchant nonsense about my thickness).

1. The height of the handrail against the wall of all safety passages is meters, and the height of the handrails against the wall of the indoor staircase is meters.

The production process of stainless steel handrails is as follows:

First of all, the elbows of the face pipe should be welded and brought to the construction site; Then go to the construction site for on-site welding, which should be installed slowly from the top floor, and pay special attention to the elbow of the face pipe of the stainless steel handrail, which should be welded on site. If you find that **is not right, cut**; Among them, the stainless steel handrail and the stainless steel elbow look smooth, each noodle restaurant only needs to weld the first foot, especially remind that the most important thing is to weld the foot of the stainless steel handrail is horizontal, and the face pipe is straight; After making the face pipes, move on to the other feet and those pipes; The last step is to polish and polish. When welding stainless steel handrails, it should be noted that the welding should not be too strong, because it is easy to deform.

In this way, the stainless steel handrail is made. Of course, this is just a theory, how to make stainless steel handrails, or go to the scene to learn the master stainless steel handrail production.

The standards for the production of stainless steel handrails generally have the following five points:

1. The most important point is whether the interface of the elbow in the turning position of the main face pipe is smooth and there are no traces. This requires that the elbow interface of the stainless steel handrail can not have traces of connection, and the sand polishing should have a bright luster.

2. The two smaller stainless steel pipes parallel to the main surface pipe of the stainless steel handrail should be in a horizontal plane with the main surface pipe, no matter how many sections are seen, or from the bottom net or from the top to the bottom, they should be parallel to the main surface pipe.

3. The stainless steel handrail tube fixed on the ground should be perpendicular to the ground.

4. The solid stainless steel pipe is called the corolla. In order to be parallel to each other with the column, the spacing error exists, but the different spacing cannot be seen with the naked eye, we can use a tape measure to measure it.

5. The column with the largest root of the stainless steel handrail should be vertical, and the interface should be smooth without traces.

There are no hard and fast rules!! Generally, it is on the inside of the stairs that is on the left.

The parallel distance from the upper inflection point to the lower inflection point of the stair tread is the length of the face tube, and the length of the elbow needs to be reduced when unloading. If the horizontal projection of the handrail of the platform section is designed and the distance between the edge of the rest platform e = b 2, the handrails of the upper and lower stairs should be connected horizontally in the rest platform section, and the height of the handrail is equal to h.

When the width of the platform is large, when the horizontal projection of the stair handrail of the platform section is the distance e > b 2 from the edge of the rest platform, the platform handrails exceeding b 2 should be horizontally connected, and the height of the handrail is equal to h.

Find the starting point c in the handrail of the sprint climb run. Equal to the height of the handrail at point A of the platform. The edge of the first step of the sprint stair at point c is d=b-e.

When the platform (including the rest platform and the sprint staircase flat step) is regarded as a first-order step, the two points are actually the same point on the same step, and the height of the handrails of the two points is naturally equal.

Some large noodles are used in the 63 (face tube), 51 (standing legs), 38 (cross braces), and 22 (columns) of Xiyouwo 63

Area conversion: anti-theft window 1 square anti-theft window (square tube: round pipe 1: ) stair handrail, protective fence (1:1:2:4).

Most of the stair handrails are equipped with round pipes. The more practical type is 63 round pipe used as a face pipe, 38 round pipe as a column, and 25 round pipe as a rung, so that the collocation is simple and generous. The thickness can be selected according to its own cost, and it is better to choose a more robust one for the family type.

If it is a public place in a shopping mall, it is recommended to use a distinctive elliptical tube as a face tube, and the following pillars can be matched with round pipes, so that it will be more beautiful to use in public places.

The office space and the shop can be matched with square pipes, which have distinctive characteristics and personalities, highlighting the grade and taste. The square tube can be made of 60*40 or 50*10 rectangles as the face tube, 40*20 or 30*10 for the column, and 10*20 or 10*10 for the rung. The thickness is usually about or.

In addition to the matching, you can also choose to use stainless steel pipes with brushed surfaces or European-style colored stainless steel pipes as handrails.

The general combination pipe has 47 32 22), (60 47 28 22), some large face pipe is 63, the combination is: 63 (face pipe) 51 (standing leg) 38 (cross brace) 22 (column), other pipe types can also be interchangeable to get a better and more suitable match.

Generally, the width of the stair tread should not be less than meters, the height of the tread should not be greater than meters, the height of the stair handrail should not be less than meters, the clearance between the vertical dry parts of the stair railing should not be greater than meters, the net width of the platform of the staircase should not be less than the width of the staircase and should not be less than meters, the lower edge of the structure of the stair platform can be walked, and the vertical height of the passage should not be less than two meters.

1. Specification for the height of indoor staircase handrails.

The height of the interior staircase decoration is 90cm, of course, this data can be changed according to the actual situation. When the length of the staircase is more than 5 meters long, the height of the stair handrail can be appropriately raised to 100cm. In addition, if there are children at home, the height of the staircase handrail should be set at 100cm for safety reasons.

2. Specifications for outdoor stair handrails.

When the height is less than 24 meters, the height of the outdoor shared staircase handrail should not be less than 105cm, and when the height is more than 24 meters, the height of the outdoor stair handrail should not be less than 110cm.

Stair handrails generally have clear requirements. Generally, the height of the handrail is 800-1150mm.

The width of the staircase is specified in the residential design code, and in other buildings, the requirements for fire evacuation must be met. The width of expressive stairs in public buildings is usually large, but attention should be paid to the relationship between the setting of handrails and the width of the staircase.

A stair handrail is a support for a stair guardrail. Stair handrails are classified according to the material: stair polymer handrails, stair wrought iron handrails, stair stainless steel handrails, stair glass handrails, stair solid wood handrails, and stair copper handrails.

There are also some special stair handrails: stair glow handrails.

stair handrails are high; 850—1100mm。

1) The height of the handrail surface is related to the slope of the staircase.

15。～30。Take 900, 30. ～45。Take 850, 45. ～60。Take 800, 60. ～75。take 750);

2) The horizontal protective railing should not be less than 1050mm;

3) When the width of the staircase is greater than 1650mm (three strands**), a handrail against the wall should be added; When the width of the staircase exceeds 2200mm (four strands**), a middle handrail should also be added.

The clear height size of the stair rest platform beam and the lower passage should not be less than 2000mm, and the clear height between the stairs should not be less than 2200mm.

The height of the handrail of the indoor shared staircase should not be lower than 900 from the center line of the tread to the upper of the handrailWhen the horizontal handrail is more than 500 years long, its height should not be less than 1000The height of the railing of the outdoor shared staircase should not be less than 1050, and the height of the middle and high-rise residential buildings should not be less than 1100

When the width of the stairwell is greater than 200, it is not advisable to choose a lattice that is easy for children to climb. The clearance between the vertical members of the railing should not be greater than 110When railings and handrails are up and down or plane transfers, it is advisable to maintain the connection.

shall not be less than 90cm, and the height of the horizontal section greater than 50cm shall not be less than, and it should be calculated from the leading edge of the step (that is, the corner of the step), and the specification has provisions.

This depends on the design needs, there are stainless steel handrails, there are ordinary seamless steel pipe handrails, and now the most commonly used multi-layer is 05J8 residential small bay staircase handrails, two size diameters, need 40 (inch and a half) 32 (inch two) 20 (6 points) 14 round bar, 18 round bar, see 05J8 2 17 for specific practices

I forgot to say, the pipes are all thin-walled pipes with thick walls, and there should be requirements on the thickness drawings, but I personally think that the thick ones can be welded on the line, after all, they only play a role in aesthetics and protection.

At present, the ** change is too big, these pipes are sold according to the ruler price, 40 of 42 yuan a 6 meters I don't remember how much the rest is, you go to the market just now to ask.

1. The railing (non-forced) is greater than or equal to.

2. Handrails greater than or equal to.

3. The wall thickness of stainless steel pipe should not be less than.

Some large face pipes use 63 63 (face tube), 51 (standing legs), 38 (cross braces), and 22 (columns).

Area Conversion: Stair handrails, guardrails (1:1:2:4).

There are no specific instructions.

However, it is noted in 06J401-1.

1. The railing (non-forced) is greater than or equal to.

2. Handrails greater than or equal to.
