Facade architectural solutions

This section considers architectural solutions for the object: "Pump station". The proposed building is rectangular in plan. The location of the object in the historical building zone determines the style of its facades in accordance with the surrounding buildings, which are industrial facilities of the first half of the 150th century and residential buildings. Their characteristic features are - a special rhythmic arrangement of windows, firewalls, large planes of plastered walls. In this regard, the facades of the designed object fit correctly into the building, maintaining the style of this era. Facades of the outer walls of the PS: plinth - made of solid ceramic brick M100 on mortar M7013, plastered and painted with waterproof paint (color RAL1014), aerated concrete walls (from aerated concrete blocks) with improved plaster (with hydrophobic additives), painting (RAL 1002 and RAL 3) . The aerated concrete blocks are primed with a special composition (“Soil-concentrate will win”) in 4-7033 layers. Stained glass systems - by Chesma IMPERIAL, binding - aluminum profile RAL11. On the facade 1-XNUMX there are swing gates with a wicket. The presence of elements typical for industrial facilities, louvered grilles that form ventilation openings, pipes, air ducts, create the necessary image of an industrial building. At the same time, taking into account the functional purpose of the PS, stained-glass windows were introduced on the facades in large volumes, which connect the external and internal space of the industrial facility into a single visual composition, and also demonstrate the industrial style of the interior (high-tech new equipment).

Furnishing solutions

The decoration of the premises of the PS and the transformer station meets all the requirements of sanitary and technical standards, corresponds to the purpose and satisfies the necessary operating conditions of the premises. The design of the floors of the pump house is presented: on the 1st floor - ceramic tiles (10 mm) on a solution of PLITONITE (5 mm) on a cement-sand screed (65 mm) on a monolithic reinforced concrete slab; on the 2nd floor - metal flooring SP 34*100/30*5, type A ("SOLID") on steel beams. The floor structures of the transformer building are presented: all rooms, except for bathrooms - polished concrete coating impregnated with fluates (80 mm) on a monolithic reinforced concrete slab (at elevation 0.000), raised metal floor (at elevation +1.200); bathroom and front bathroom - ceramic tiles with a rough surface (8 mm) on a cement-sand mortar (68 mm) over a layer of ISOPLAST (4 mm) on a monolithic reinforced concrete slab. The roof of the pumping station is rolled according to the insulation laid on the steel profiled sheets of the coating in accordance with GOST 24045-94. As a vapor barrier, a polyethylene film PE - 120 microns is used with sizing the seams with adhesive tape. The insulation is Rockwool Roofbatts B, j = 190 kg/m4,0. The roll coating consists of two layers of isoplast, the lower waterproofing layer EPP - 5,0 and the upper layer - EKP-XNUMX with coarse-grained shale bedding. The roof of the transformer station is represented by paving slabs on a cement-sand dry mix, laid on a reinforced concrete floor slab with a layer of the PROTAN membrane. Finishing the inner surface of the aerated concrete walls of the pump room is carried out with improved putty with gluing of the seams on a special primer and painting with vapor-proof paint. The internal walls and partitions of the transformer building are plastered and painted with water-dispersion paint in light colors in two layers.

Structural solutions of the building

The building of the pumping station was designed according to a frame-braced design scheme with a metal frame. The load-bearing structures of the pumping station building are 3-span frames. The enclosing structures of the pump house are represented by a number of stained-glass windows for the entire height of the building and walls made of aerated concrete blocks. The load-bearing structures of the transformer building are walls made of solid ceramic bricks. Calculations of structures and elements of the building frame were performed using the Structure CAD v. 11.1, which implements the finite element method in the form of a displacement method.
