Abstract

A toughened glass manhole cover for urban roads is provided with a manhole cover body made of toughened glass and a rubber ring arranged around the toughened glass manhole cover body, wherein, the toughened glass manhole cover body is a single-layer body or is bonded together by a plurality of layers, the toughened glass manhole cover body also can have a plurality of geometric shapes, the cross section of the rubber ring is L-shaped, and the four sides and the lower edge of the manhole cover body can be covered by the L-shaped annular groove of the L-shaped rubber ring for damping and sealing. According to operating requirements, an L-shaped groove air hole can be arranged on the inside of the L-shaped rubber ring. The utility model has the advantages that: the manhole cover can improve the physical characteristics of a prior manhole cover, prolong service life and beautify urban roads, parks, green areas and squares with safety and reliability, good appearance and durability, easy maintenance and construction.

Description

The tempered glass well lid

Technical field

The utility model relates to the tempered glass well lid that uses on a kind of urban road.

Background technology is present, the casting iron well lid that in the urban road pipe-line construction, generally uses, because of its poor safety performance, outmoded, the frequent robber of outward appearance decrease, are easy to fracture etc., brought great inconvenience to pipeline construction and working service, also be difficult to adapt to the needs of modern city construction development simultaneously.

Summary of the invention

The purpose of this utility model provide a kind of safe and reliable, attractive and durable, be easy to safeguard, the tempered glass well lid of easy construction.

For achieving the above object, the utility model is taked following design scheme:

A kind of double-deck tempered glass well lid that is used on the urban road has a well lid body, and it is characterized in that: described well lid body is to be made by tempered glass, is provided with a rubber washer around this tempered glass well lid body.

Described tempered glass well lid body profile is respectively multiple geometry, as, circular, oval, square, rectangle, triangle, pentagon, hexagon, octagon, rhombus, parallelogram etc.

Described tempered glass well lid body is single or multiple lift bonding making mutually.

The section shape of described rubber washer is L shaped, in the L shaped annular groove that four limits and the lower limb of well lid body can be coated on L shaped rubber washer, plays the effect of damping sealing.

According to instructions for use, can be provided with L flute profile air vent in the inboard of L shaped rubber washer.

The utility model has the advantages that: safe and reliable, attractive and durable, be easy to safeguard, easy construction, improved the physical property of pipeline manhole lid, can prolong its application life, beautified urban road, park green land, the environment on square.

The specific embodiment

Referring to Fig. 1, shown in Figure 2: a kind of tempered glass well lid that is used on the urban road, a well lid body 2 is arranged, described well lid body is to be made by tempered glass, is provided with a rubber washer 1 around tempered glass well lid body.

Described tempered glass well lid body profile is respectively multiple geometry, as, circular (see figure 1), ellipse, square (see figure 3), rectangle (see figure 5), triangle, pentagon, hexagon (see figure 4), octagon (see figure 6), rhombus, parallelogram etc.

Described tempered glass well lid body is single or multiple lift bonding making mutually, and Fig. 2 is double-deck tempering glassy phase bonding making mutually, according to different specifications and instructions for use, can select single or multiple lift tempered glass bonding making mutually for use.

According to instructions for use, can be provided with L flute profile air vent 3 in the inboard of L shaped rubber washer.This round manhole cover 2 cooperates circular L shaped rubber washer 1, and this square well lid 4 cooperates square L shaped rubber washer 5.

This toughened interlayer glass well lid can adopt two planks tempered glass, and employing high strength PVB bonding film, make two bonding glass together through high pressure, through after glass surface sandblast, the colored glaze processing, be used in the capping aspect of municipal sewage, rainwater, cable, water meter chamber simultaneously.

This tempered glass well lid, be that the collection environmental protection is attractive and durable, function products such as easy care easy construction, can stand-40 ℃-327.5 ℃ the great change temperature difference and not broken, broken back fragment granule does not have acute angle and can avoid human body is damaged, through detecting fully, the performances such as mechanics that compared cast iron and interlayer tempered glass, adopted the birefringence principle, the three-point bending strength experimental technique, methods such as lifting and lowering method have detected bearing stress respectively, bending strength and impact failure intensity, the result is that every performance of tempering double-layer glass product all is better than cast iron products, and has following six big characteristics:

Thermal insulation is good; Sound insulation is good; Anti-freezing frost performance is good, and dew point can reach-50 ℃; Good airproof performance moisture dust is difficult for entering; Good stability, withstand voltage being difficult for breaks, long service life; Flexibility is by force applicable to any ambient condition.

Use tempering double-layer glass well lid and can solve the poor safety performance that casting iron well lid exists better, outward appearance is outmoded, often steal problems such as decreasing, be easy to fracture, reach the thermal insulation, sound insulation, the anti-freezing frost that improve pipeline manhole lid, sealing, stability, flexibility are with application life that prolongs well lid and the purpose of beautifying the modern city environment.

The effect of this well lid material therefor and processing:

Plate glass and tempering: the one, it is pollution-free, do not corrode, and the 2nd, resistance to compression behind the glass tempering, impact resistance is strong, makes it durable temperature resistance difference fusion.

The PVB bonding film: bonding force is strong, does not rupture

Colored glaze: green or steel gray and well lid environment for use, as road, the color environment of sidewalk, park, greenery patches, wide sound is harmonious.Glaze is wear-resisting behind high temperature sintering, does not come off, and does not fade.

Sandblast: destroy the glass surface brightness,, prevent light pollution with anti-skidding.

The hard rubber packing ring: L type rounded washers mainly is the mitigation power effect between glass and the aboveground edge when playing the piping shaft glass cover and installing.

Processing method:

(1) circle that the plate glass sheet is cut into φ 600mm is as the criterion with well head upper edge size, and the limit portion of circle is worn into the splay configuration limit, and per two glass circles are a product.

(2) with the one side sandblast of a glass circle, carry out the colored glaze printing afterwards.

(3) glass is carried out tempering.

(4) it is bonding with the PVB bonding film a slice colored glaze Circular glass and a slice white glass to be carried out high pressure.

The L type hard rubber gasket sleeve that tempering is pressed from both sides people's same size is installed on the upper edge pedestal of pipe fly together.
