Paviny type jointable prefabricated road-face brick combined structure

Abstract

The invention belongs to a paving connectible prefabricated road brick combined structure, and its main technical characteristic: a square road brick is divided into upper and lower layers of the same size, staggered along the diagonals of top plane of the square road brick, where a reinforcing web is laid between the upper and lower layers, and two adjacent sides of the reinforcing web overlap two corresponding sides of the lower layer of the road brick and the two other sides of the reinforcing web extend along the diagonals of top plane of the lower layer of the road brick out of the two corresponding sides of the lower layer of the road brick, and the bottom plane of the upper layer of the road brick overlap the two extended sides of the reinforcing web. And it makes road surface have good whole stability and inter-road brick embedded constraint and horizontal tensile performance be strong.

Description

technical field [0001] The invention belongs to pavement bricks in the field of building materials, in particular to a pavement-type jointable prefabricated pavement brick composite structure. Background technique [0002] In order to beautify the people's living environment, pavement bricks are usually laid on the pavement of people's living and working places, such as squares, sidewalks and roads in residential areas, and prefabricated pavement bricks are often used. This pavement construction method is fast and efficient. The advantage of being partially replaceable has been generally recognized by people. However, the pavement connection of the existing pavement bricks adopts the upper and lower straight joints, the joints are not strict, the overall vertical embedded restraint and horizontal tensile strength are small, the horizontal integrity is poor, and the service life is short. The paved pavement is prone to mud pumping along the brick joints after being soaked in...

AI Technical Summary

Problems solved by technology

However, the pavement connection of the existing pavement bricks adopts the upper and lower straight joints, the joints are not strict, the overall vertical embedded restraint and horizontal tensile strength are small, the horizontal integrity is poor, and the service life is short. The paved pavement is prone to mud pumping along the brick joints after being soaked in water, and weeds are easy to grow from the brick seals on roads with few pedestrians and vehicles; especially when the pavement is subjected to the horizontal force of rapid braking of vehicles , the pavement bricks lack the overall cooperative resistance of mutual restraint, and it is easy to cause local pavement uplift, pull apart, or pavement bricks to be overturned and broken to cause pavement damage, etc.

This kind of phenomenon is not uncommon, affects people's life to a certain extent, and increases the maintenance cost of the road
