Abstract

The utility model relates to a composite material manhole seat, which is made of BMC molding compounds. The vertical body of the manhole seat has the structure of a thin top and a thick bottom, and the thickness is from 5 mm to 20 mm. The thickness of a supporting body is from 3 mm to 15 mm, and the thickness of the outer edge is from 3 mm to 15 mm. Three-supports are uniformly distributed between the vertical body and an out line, and the thickness of each of the three-supports is from 3 mm to 10 mm. The manhole seat is matched with a BMC die pressing manhole cover or a rainwater grate, manufacturing cost can be reduced greatly and the competitive position of the price of the manhole cover and the rainwater grate can be improved.

Description

Composite well seat

Affiliated technical field:

The utility model relates to a kind of accessory of composite drain cover---composite well seat.

Technical background:

Composite drain cover mainly seriously grows up at casting iron well lid is stolen, and along with the progress and development of composite material, it is more and more ripe to do the well lid technology with composite material, and manufacturing enterprise is also more and more.And along with the successful Application of composite drain cover, the user just progressively accepts this well lid.

The BMC moulded well covers because of stable material quality, processing presentation quality simple, product is better, cost of manufacture is relatively low, obtained very fast development in recent years, but the materials of BMC moulded well covers are bigger to the cost impact of well lid, and in order to reduce the cost of well lid, people work on well lid one after another.

Because of well lid has certain thickness, especially well lid centre thickness is thicker, often requires the height of well seat also higher, and the consumption of material is more, causes cost higher.The patent No. is that 2003201314766 " composite material manhole seat " discloses a kind of well seat outer ring horizontal direction or seat bottom vertical direction for taking out heart frame construction, the inspection shaft seat of the uniform vertical rib of well seat periphery wall, this well seat has alleviated the weight of well seat, reduced cost of production, increased contact area with concrete material.But the design of the mould of this well seat is complicated, and the production and processing difficulty is big, and product waster rate is higher.

The utility model content:

To be exactly that design is a kind of can satisfy instructions for use and cost is low, make simple, cost rate is high BMC composite well seat to the purpose of this utility model.This well seat can be made circle, square, rectangle etc. and be suitable for the well lid of corresponding size and material and the accessory of rain grid made.

The utility model is described in further detail below in conjunction with drawings and Examples, but therefore the utility model is not limited among the described scope of embodiments.

Accompanying drawing is a partial sectional view of the present utility model:
