Abstract

A plastic drainage plate and its construction way for greening in top plates of a building is provided, which is an environmental-friendly and energy-saving tech for greening on top plates of a building, is a new tech the state is spreading vigorously. The invention comprises an invention of drainage plate and an invention of two construction ways. The shape of the product has reinforcing slot, hollowed plane and a pivot point for a water-accumulating cup, integrates such functions as pressure resisting, water draining and water accumulating. The construction way 1 is to adhere a plastic plate on the drainage plate at the edge of a building, which can guarantee the smoothness of the water outlet, is an important guarantee for the water drainage system of the building; the construction way 2 is to add and spread some concrete pivot points in the road places, which can not only guarantee smooth drainage, but also can improve the pressure resistance of the road.

Description

Plastic draining board and job practices in the greening of building top board

One, technical field

The present invention is placed on plastic draining board and geotextiles on the building top board to repave planting soil, plant the method for greening, the block plastic draining board product invention of a kind of concrete grid is arranged in this total inventive concept, with the job practices invention at various band drains, the present invention has three independent claims.

Two, technical background

Underground construction top board and roofing can be referred to as the building top board, and country actively supports to carry out planting technique, the band drain of the various ways of existing external import and domestic development on the market, and basic classification can have the flat band drain of web-like; The block band drain that has injection moulding to produce; The band drain that also has the sleave shape, I am existing multinomial invention on the flat band drain of web-like.The present invention proposes a kind of novel block band drain, integrates functions as one, and has also considered the problem of aspects such as packed and transported, can be applied to major works, also can be applicable to the flower garden greening of resident family.

The job practices of various band drains is completely to spread geotextiles on band drain, lacks rational way on structure node, and I propose a series of inventive method according to basic principle from put into practice engineering.

Three, summary of the invention

A. this product invention is the block band drain of a kind of grid, adopts the empty dull and stereotyped form of structure that connects with the cup-shaped fulcrum of one deck thread, and the invention intention is to make the hypotenuse groove on platen surface, and connects with fulcrum.This product has following advantage:

1, groove of the present invention plays the effect of polywater, the water on plane can be directed in the cup, helps virescence maintenance;

2, the groove of plate face has improved dull and stereotyped rigidity, and the plane Load Transfer to fulcrum, has been improved the bending resistance of product;

3, groove design is oblique, has considered that the levels product is superimposed mutually, non-sticking again angular relationship.

This product is injection moulding production, and the grid size is between 300 * 300mm～800 * 800mm; The fulcrum height is at 20mm～80mm; The hasp that mutual connection can be arranged between the grid also can not need hasp, and recess width is 1mm～12mm, and the degree of depth is 1mm～12mm.After the grid band drain completely spread, topped again one deck geotextiles just can the greening of earth backing kind.

B. be a specific product invention more than, introduce the invention of job practices again:

1, large-area rainwater finally is to discharge from the building edge, in order to prevent square ponding, the water outlet at edge just must be unobstructed, and present way is to cover band drain with geotextiles, can be sagging in the geotextiles of edge, will reduce effective drainage area like this, even stop up drainage outlet.The present invention is sticking plastic plate at the band drain edge, and width is 30～150mm, repaves geotextiles, just can guarantee effective draining space.

2, in the architecture greening road is arranged, road partly needs higher compressive strength, the present invention at first completely spreads band drain, on band drain with the white powder site of road that draws, on the band drain at road position, scatter fulcrum again with fine-stone concrete, about 5%～80% area, current equally can be unblocked like this, and local compressive strength also is improved.

Four, description of drawings

Fig. 2 is block band drain sectional drawing;

Fig. 3 is block band drain groove sectional drawing;

Fig. 4 is that the water outlet edge of band drain adds sticking plastic board sectional drawing;

Fig. 5 is the sectional drawing that scatters the pea gravel concreten fulcrum on the band drain at road position.

Five, specific implementation method

Fig. 1 is the some on the block band drain of the present invention plane, the 1st, and cup-shaped fulcrum, the 2nd, the surface plate that thread is empty, the 3rd, the UNICOM of the groove on the surface plate, groove and fulcrum;

Fig. 2 is the sectional drawing of Fig. 1;

Fig. 3 is the section of plane groove, the 2nd, and surface plate, the 3rd, groove.Fig. 1～Fig. 3 is product invention;

Fig. 4 is a building top board edge shop band drain 4 earlier, repaves plastic board 6, repaves geotextiles 5 at last; Band drain 4 comprises various types of band drains, is the method invention;

Fig. 5 is the road position of building top board, and shop band drain 4 scatters 5%～80% fine-stone concrete fulcrum 7 more earlier, repaves geotextiles 5 then, is the method invention.

Claims

1. the plastic draining board in the greening of building top board is the block band drain that injection moulding is produced, and it is characterized in that: thread empty plane and cup-shaped fulcrum are arranged, and fluted on the plane between the fulcrum.

2. the plastic draining board in the building top board greening as claimed in claim 1, it is characterized in that: depth of groove is 1～12mm, width is 1～12mm.

3. the job practices in the building top board greening is to repave geotextiles on various plastic draining boards, it is characterized in that: earlier sticking plastic board on the various band drains at building top board edge, repave geotextiles, and can guarantee the space of delivery port and unobstructed.

4. the job practices during the building top board is afforested, be on various plastic draining boards, to repave geotextiles, it is characterized in that: scatter 5%～80% fine-stone concrete fulcrum earlier on the band drain at road position, repave geotextiles, the bearing capacity that can improve the road position does not influence draining again.
