Heating and ventilation static pressure box structure and construction method thereof

Abstract

The invention relates to a heating and ventilation static pressure box structure and a construction method thereof. The heating and ventilation static pressure box structure includes a stand ladder, vertical members, an air supply pipe, a steel skeleton, a boom and a static pressure box bottom plate; the stand ladder, the vertical members and the static pressure box bottom plate define a closing space; the vertical side face of the stand ladder is provided with air supply outlets at intervals in the longitudinal direction; the lower surface of the stand ladder is provided with a first thermalinsulation layer, a steel wire gauze and a mortar layer; the steel skeleton includes an inclined section frame and a horizontal section frame; the upper end and the lower end of the steel skeleton areconnected with the vertical members on the corresponding sides through first connection members; the upper end of the boom is connected to the vertical side face of the stand ladder through a secondconnection member, and the lower end of the boom is connected to the steel skeleton; the static pressure box bottom plate is paved on the top surface of the steel skeleton and includes a bottom panel,a second heat insulation layer and a top panel which are sequentially arranged in sequence from bottom to top. The heating and ventilation static pressure box structure solves the technical problemsthat a traditional static pressure box structure is prone to generating cold and hot bridges, fluffy catkin and noise, the energy loss is generated, condensed water is formed, the space is narrow, andconstruction operation is difficult.

Description

technical field [0001] The invention relates to the field of decoration engineering, in particular to a HVAC plenum structure and a construction method thereof. Background technique [0002] The audience area of ​​the training hall of a certain project is stepped seats, and the air supply air from the air conditioner is sent from the main air duct through the static pressure box, and is sent out from the swirling air outlet with adjustable air volume under each stepped seat. In order to ensure the comfort of watching the game in the spectator area, and to avoid the wind behind the head and strong blowing sensation, the air supply system of the plenum box is required to have the basic functions of large air supply volume, no cold bridge, and low noise. The original design adopts the static pressure box of reinforced concrete structure, in which the bottom plate is 150 thick reinforced concrete bottom plate, and the bottom plate also acts as the partition wall of the fire prot...
