RU215158U1 - CONCRETE BLOCK FENCE - Google Patents

Abstract

The utility model relates to the means of ensuring safe traffic on highways and artificial structures and is designed to separate oncoming traffic lanes on highways and prevent the spread of an emergency to the oncoming traffic lane in case of its occurrence, as well as to ensure safety from the side of the roadside (side guardrails) at high embankments. The concrete block of the fence includes a body with cavities and mounting loops located on the upper surface, with a recess into the body, with branches bent in a horizontal plane. The cavities can be made open from below, in the form of notches open from the bottom and from the back surface of the block, in the form of notches open from the bottom and from the ends. The cavities and recesses are separated by bridges. The technical result consists in reducing the weight of the fencing block while maintaining its strength properties, which reduces its cost and simplifies transportation, installation and dismantling, as well as loading and unloading operations.

Description

Technical field

The utility model relates to the means of ensuring safe traffic on highways and artificial structures and is designed to separate oncoming traffic lanes on highways and prevent the spread of an emergency to the oncoming traffic lane in case of its occurrence, as well as to ensure safety from the side of the roadside (side guardrails) at high embankments. Due to the presence of cavities in the block, an additional damper is provided in the event of a collision. The road reinforced concrete fence significantly reduces the risk of unauthorized crossing of the highway by pedestrians in a place not established by traffic rules. In addition, the product can be used as a support structure for various elements: enclosing, advertising, stands and others.

Prior Art

Blocks of road barriers play an important role in road infrastructure. Road barriers are special reinforced concrete products. They are designed to ensure road safety (for example, to carry out an emergency forced stop in the event of loss of control over transport) and to minimize damage in the event of an accident. Also, with their help, you can redirect dense car traffic.

A block of a road separating barrier is known, containing a hollow body made of polymeric material, made of two identical parts connected along the contour, made of polyethylene (patent RU 8373, publ. 16.11 1998).

From patent RU 68529, publ. 11/27/2007, a block of a road dividing fence made of plastic, with the possibility of filling with liquid, containing a body with an open bottom cavity with an upper and lower base, end walls located at an angle to the bottom base, longitudinal walls made in the form of double panels with a gap, one of the end walls of the housing has a latch located under it in the form of a boss, and the other end wall of the housing has a through hole for installing a latch of a nearby block in the process of assembling a road separating barrier.

The disadvantage of the known fences is that they are made of plastic, this material, with all the advantages, is not durable, it requires fixing and weighting.

Concrete parking barriers are now used everywhere to control the movement of vehicles and pedestrians in certain areas.

Any concrete fence offers a number of advantages, standing out favorably from other materials and types of products: long service life, resistance to various external influences and preservation of appearance throughout the entire period of operation, practicality, no need for special care, affordable cost, wide choice height, dimensions, weight, shape, design of products, ease of installation and ease of transportation, high weight, which makes it difficult to move the fence by vandals, resistance to scratches, mechanical stress.

From the patent for invention RU 2283913, publ. 09/20/2006, a road barrier made of concrete is known, made in the form of a reinforced concrete beam with a broadened base resting on a strip foundation located under it in the form of a slab with openings for anchors, also made from the lower part of the broadened base of the reinforced concrete beam along a vertical axis passing through the center masses of the cross section of a reinforced concrete beam.

The design of a reinforced concrete road block is known, made in the form of a parallelepiped with an expanded base, mounting loops located in recesses on the upper surface of the block (“Rules for earthworks, installation of temporary fences, placement of temporary facilities in Moscow”, approved by Decree of the Government of Moscow dated 19 May 2015 No. 299-PP https://files.stroyinf.ru/Data2/1/4293764/4293764085.pdf).

The disadvantage of the known fence is a large weight, which imposes restrictions on assembly and dismantling and transportation.

The essence of the utility model

The technical result of this utility model is the simplification of transportation, installation and dismantling of the concrete block of the fence. The implementation of cavities inside provides lightening of the product as a whole, which means simplification and facilitation of transportation to the installation site, which will save logistics.

The technical result is ensured by the fact that the concrete block of the fence, including the body with front, rear, top and end surfaces, is made with cavities and mounting loops located on the upper surface of the block with a recess into the body with branches bent in a horizontal plane.

The block can be made straight in the form of a parallelepiped or with an expanded base, with a front surface made of vertical and inclined parts, a horizontal straight top and vertical straight end and rear surfaces. The body of the block can be made symmetrical and not symmetrical.

On the end surfaces of the block, it is possible to make protrusions, for example, to install panel racks.

The outer dimensions of the support block can be made in accordance with the "Rules for excavation, installation of temporary fences, placement of temporary facilities in the city of Moscow", approved by Decree of the Government of Moscow dated May 19, 2015 No. 299-PP, in the form of a concrete rectangular parallelepiped with a height 600 mm, 400 mm wide and a front inclined surface in its upper part with a top surface width of 250 mm and a front vertical surface height of 200 mm, but can be designed to the Customer's dimensions and have other dimensions.

The branches of the mounting hinges are recessed into the body from the upper surface by 20-300 mm, and the branches bent in the horizontal plane are made with a length of 200-1000 mm, and can be bent both in opposite directions and in one direction.

The execution of cavities inside the body of the block causes the implementation of embedded parts in the form of mounting loops of the original design. Each mounting loop can be made with a vertical straight lug, which can be located in a recess, with a recess into the body with loops bent in a horizontal plane relative to the lug. The horizontal branches of the mounting loops are made elongated with hooks at the ends, which provides better anchoring of the branches of the loops with concrete.

The cavities in the body are separated by jumpers. Cavities can be made different in shape and section, in the form of a truncated pyramid, parallelepiped, square, triangle, semicircle, trapezium, etc.

The body of the block can be made with cavities separated by a jumper, open only from below.

It is possible that the body is made jointly with cavities open at the bottom, separated by bridges, and with recesses open at the bottom and at the ends.

Or, the cavities can be made in the form of recesses, open at the bottom and behind, separated by bridges. The recesses can be rectangular, triangular, round, trapezoidal.

The maximum size of the cavities inside the block is made taking into account the minimum required thickness of the block, for laying the mounting loop in the concrete body, while observing the protective layers up to the working reinforcement of the loop. Preferably, the volume of the cavity in the block body is 5-70% of the total volume of the block.

The block can be made symmetrical, with inclined front and rear surfaces, or the front surface has an inclined and vertical parts. The depth of penetration of the branches and their length are made in accordance with the Technical Recommendations TR94-2003, Sling loops for precast concrete and reinforced concrete structures, design, calculation and testing, Moscow 2003.

The block can be used as a supporting block for enclosing structures (sections) in the form of panels or for information or advertising structures. Racks with panel can be fixed to the unit by bolting, bracketing or welding.
