Abstract

Poduszka zderzeniowa słupkowa nakierowująca, składa się z co najmniej dwóch słupków (1) ustawionych w rzędzie, zbrojonej płyty betonowej (2) oraz co najmniej jednego panelu bocznego (3), przy czym słupki (1) są podzielone na sekcję górną (1a), środkową (1b) i dolną, a kąt pomiędzy sekcją górną (1a) i środkową (1b) wynosi od 5° do 175°, w płycie betonowej znajdują się tuleje kotwiące w ilości równej ilości słupków (1), sekcje dolne słupków są osadzone luźno w tulejach kotwiących, w części środkowej słupka (1b) po stronie przeciwnej do kierunku pochylenia sekcji górnej (1a) znajduje się inicjator przegubu plastycznego (1d), panele boczne mają postać połączonych teleskopowo rur (3a, 3b). Poduszka charakteryzuje się tym, że panele boczne (3) są połączone przegubami płaskimi (4) z pierwszym i ostatnim słupkiem poduszki zderzeniowej.The steering post crash cushion consists of at least two posts (1) arranged in a row, a reinforced concrete slab (2) and at least one side panel (3), with the posts (1) divided into an upper section (1a), middle (1b) and lower, and the angle between the upper (1a) and middle (1b) sections is from 5° to 175°, there are anchor sleeves in the concrete slab equal to the number of posts (1), the lower sections of the posts are loosely embedded in the anchor sleeves, in the central part of the post (1b), on the side opposite to the direction of inclination of the upper section (1a), there is a plastic hinge initiator (1d), the side panels have the form of telescopically connected pipes (3a, 3b). The cushion is characterized by the fact that the side panels (3) are connected with flat joints (4) to the first and last pillars of the crash cushion.
