Stands of temporary road signs. Strengthening openings. General requirements for installing road signs
Buy telescopic stands from the Vostok Formwork company. But no matter how good the formwork is, for a durable and monolithic component of the building, one more component will be needed, these are high-quality supporting and auxiliary elements.
Floor formwork on telescopic racks - as a method of pouring monolithic floors concrete
So, you have decided to buy formwork stands from the manufacturer, our engineers will calculate the quantity you need in a short time
Let us describe a simplified diagram of this design:
It looks like this - 1) First of all, a tripod is installed, then a stand is attached to it. In laying a wooden beam BDK for formwork uses a uniform formwork or the so-called crown. 2) After installing and securing the racks, a plywood deck with cut-offs is laid on top, then a concrete mixture is poured onto it. Such a system is floor formwork on telescopic stands.
Advantages of using telescopic stands
- Easy to transport
- Quick installation and disassembly of the structure (including with a unifork and a tripod)
- Safety and durability
- Applicable even in harsh climatic conditions
The use of formwork on telescopic stands in construction makes it possible to obtain various monolithic structures with a flat surface, without any special additional processing.
Telescopic formwork stands - all sizes at low prices
Telescopic stand for formwork – serves as a support for horizontal panels of structures. It can also perform the fixing function of horizontal components of formwork systems for some time. We offer telescopic formwork stands in the following standard sizes: 1700, 3100, 3700, 4200, 4500 and 5500. Their height is adjustable within these limits. In our company you can reallybuy telescopic stands from stock.
The main criteria for a telescopic construction stand in production
Function construction tripod lies in the reliable and quick installation of the racks - it helps to firmly and strictly vertically fix the support, and this in turn reduces horizontal loads and vibration at the time of supplying the solution.
The construction formwork is fixed in the upper part of the rack and acts as element holding the plywood-wood beam BDK-1. At the same time, it can serve as a holding element for one or more beams, if they overlap. This unit at first glance seems simple, but in fact it is key - after all, the entire flood deck is supported on it. Therefore, you should take a responsible approach to choosing a construction fork.
Today, there are a huge number of companies on the market offering racks and other components of floor formwork, but only a few can offer their customers products that meet the stated load-bearing standards. Our company is one of the few in Moscow that supplies reliable and first-class equipment (including telescopic stand, price which depends on its size). Well, the answer to the question is " How long does the formwork last?" you will find on our website in the "Questions/Answers" section.
And if you can't affordbuy volumetric formwork, then it is possible for us for formwork.
Table. Loads on the telescopic stand
In this table we have indicated the maximum load-bearing values for racks in kg. When calculating the loads on the formwork system, take into account the demand factor from 1,2

GENERAL REQUIREMENTS FOR INSTALLING ROAD SIGNS
Road signs must be installed in accordance with the requirements of GOST R 52289-2004. The types of signs, their number, and installation location are determined by the location approved by the relevant State Automobile Inspectorate. The installation of road signs, as well as their removal on specific sections of roads, is carried out with the permission of the State Automobile Inspectorate of the territory, region, autonomous republic. The installation of each sign and, above all, signs introducing various restrictions, must be justified. The total number of signs on a road section should be as minimal as possible. Short-term or seasonal signs are installed only for the period when they are necessary, and are immediately removed after the reason for installing the sign has been eliminated.
In one cross-section of the road, it is allowed to install no more than three signs, excluding duplicates and additional information signs (plates). In this case, they must be placed: on supports, columns and pillars (masts) horizontally (which is preferable) or vertically; on guy wires, frames and brackets located above the roadway - horizontally at the same level.
Methods for installing signs on roads outside populated areas.
On roads outside populated areas, sign supports should be installed outside the shoulders on berms sprinkled to the side of the road (Fig. a), embankment slopes (Fig. b), on the right-of-way behind the side ditch (Fig. c) or above the roadsides (Fig. e ). The distance from the edge of the roadway to the edge of the sign closest to it should be from 0.5 to 2 m, and to the edge of signs indicating preliminary directions - from 0.5 to 5 m. On mountain roads, it is allowed to install supports on the side of the road in cramped conditions. In this case, the distance between the edge of the roadway and the edge of the sign closest to it must be at least 1 m (Fig. d). It is recommended to install supports behind the parapet on the side of the slope, build them into parapet blocks, or install them between individual parapet blocks. In areas where beam or cable fences are installed, it is recommended to place sign supports behind the fences on the side of the slope, closer to the fence supports, or fixed directly to the fence supports. It is permitted to install signs on the median strip to duplicate signs located on the right side of the road or above the roadway. On a concave profile dividing strip, supports should be installed closer to the roadway in the direction of travel for which the sign is intended. The edge of the sign should not protrude beyond the fence line (Fig. e).
Methods for installing advance direction signs
Preliminary direction signs and distance indicators should be installed on supports located on berms sprinkled to the side of the road (Fig. a), slopes of embankments and excavations (Fig. b) or on the right-of-way behind the side ditch (Fig. c). In areas where fences are installed, sign supports should be located closer to the fence supports so that the distance between the edge of the sign and the support is at least 0.75 m (Fig. d). It is recommended to attach preliminary direction indicators to inclined supports installed next to the roadbed (Fig. e) or on the slopes of excavations (Fig. f). This design of the supports allows the edge of the sign to be placed at a distance of 0.5 - 1 m from the edge of the roadbed, without installing a fence. In areas where supports cannot be installed on an embankment slope or next to the roadbed, it is recommended to place sign boards above the curbs or roadway on L-shaped supports (Fig. g). On roads of categories I - II, signs can be installed above the roadway on U-shaped supports or guy wires. The supports of load-bearing structures must be located on the berm at a distance of at least 0.5 m from the edge of the road or the edge of the dividing strip (Fig. h, i).
Methods of installing signs in populated areas.
In populated areas, signs should be installed on individual supports (Fig. a), on the same column with a traffic light (Fig. b), on brackets attached to lighting masts, supports of the contact network of trams and trolleybuses (Fig. c, d) or the walls of buildings ( Fig. e), on guy ropes attached to buildings (Fig. f), stretched between the building and a special support or between lighting masts (Fig. g). It is allowed to install signs above signal bollards with artificial lighting (Fig. h). The distance from the bottom edge of the sign (excluding the plate) to the surface of the road surface should be: from 1.5 to 2 m - when installed on the side of the road outside populated areas, from 2 to 4 m - in populated areas; from 5 to 6 m - when placed above the roadway or curb. Signs must be removed from the lighting network wires by at least 1 m, and from the high voltage network wires by at least 2.5 m (Fig. e). Within the security zone of high-voltage lines, hanging signs on guy wires is prohibited.
Signs are placed above the curb (or roadway) in the following cases:
A) in areas where lateral placement of the sign is not possible;
b) when this is the only way to ensure good visibility of the sign;
c) if necessary, regulate traffic in separate lanes;
d) with heavy traffic of large vehicles.
The sequence of arrangement of several signs on one support
Depending on the relative position of the signs on one support, the order of their location is determined in accordance with the figure below. It is preferable to place signs horizontally.
The order of placing signs of different groups on one support should be as follows: priority signs; warning signs; prescriptive signs; prohibition signs; information and directional signs; service signs. When placing signs of one group on one support, the order of their arrangement is determined by the number of the sign in the group.
Examples of placing sign 5.7.1 or 5.7.2 on the same support with other signs
Exception. If several signs are installed when entering a one-way road, then signs 5.7.1 and 5.7.2 are located above the other signs.
Road sign posts can be made of various materials that provide sufficient stability under the influence of the calculated wind load, when washing signs manually and mechanically, and also exclude the possibility of intentional damage to the posts by individuals. For this purpose, stands made of pipes with a diameter of 76 mm are most often used.
The length of road sign posts is determined from the condition that the height of the lower edge of the sign above the surface of the roadway must be at least 2 - 2.5 m plus the amount of penetration of the post into the ground. In this case, the upper edge of the sign should rise above the upper end of the post by 0.15 m.
