In the figure: 1. a decorative layer; 11. a granite layer; 12. a cement mortar layer; 2. stainless steel well covers; 21. a stainless steel basin; 22. a stainless steel frame; 3. a steel keel; 31. a galvanized square tube main beam; 32. the galvanized square tube secondary beam.
Detailed Description
The technical solution of the present invention is further described below with reference to the following embodiments:
the utility model provides a decorative cover of large-span access hole, decorative layer 1 including the from top to bottom setting gradually, stainless steel well lid 2 and steel joist 3, the upper surface at stainless steel well lid 2 is pour to decorative layer 1, stainless steel well lid 2 includes stainless steel basin 21 and the stainless steel frame 22 that a plurality of linearity were laid, steel joist 3 includes two zinc-plated square tube girder 31 and a plurality of zinc-plated square tube secondary beam 32, zinc-plated square tube girder 31 and the perpendicular fixed connection of zinc-plated square tube secondary beam 32, the equidistant linear arrangement of each zinc-plated square tube secondary beam 32, stainless steel well lid 2 covers and establishes on the access hole, stainless steel basin 21 and 3 fixed connection of steel joist. The bottom of stainless steel apron has been installed steel joist 3 and has been increased apron self intensity, reaches the apron top and walks people's requirement, through the stainless steel basin 21 that falls into a plurality of equalling with the apron to with stainless steel basin 21 and stainless steel frame 22 fixed connection, satisfy the operation requirement of large-span.
The decorative layer 1 comprises a granite layer 11 and a cement mortar layer 12. Wherein the thickness of the granite layer 11 is 30mm. The granite has good frost resistance and high hardness, and people can pass through the cover plate. The thickness of the cement mortar layer 12 is 22-30mm. The cement mortar layer 12 should not be too thin to prevent hollowing or cracking, nor too thick to increase costs. In the cement mortar layer 12, the mass ratio of cement to mortar is 1. The cement mortar layer is used as an adhesive for granite and stainless steel manhole covers 2.
The stainless steel frame 22 is fixed to the manhole by expansion bolts. The fixing function of expansion bolts is stronger, and the weight that can bear is very heavy, when fixed stainless steel frame 22, does not influence the bearing performance of apron.
The gap between the cover plate and the access hole is filled with yellow sand. The yellow sand can be backfilled in place, and the sand with water can be more compact.
Four corners of the stainless steel basin 21 are provided with maintenance hanging holes. The arrangement of the access hanging hole is convenient for installing and disassembling the cover plate.
The present embodiment is only for further explanation and is not intended to limit the present invention, and persons skilled in the art can make non-inventive modifications to the present embodiment as required after reading the present specification, but all the embodiments are protected by patent law within the scope of the present invention.
