The present invention provides an exhaust gas discharge device for a fire engine in a fire station, the device comprising: a base frame inserted into a guide groove formed on the floor of the garage of the fire station; a lifting frame connected to the upper part of the base frame to slide in a vertical direction; a suction hood having a suction hole on one side while having a container shape including a space unit inside thereof; a discharge pipe unit for guiding the exhaust gas of the fire engine in the garage to be discharged to the outside of the garage; a discharge fan for generating a suction force for the exhaust gas to be discharged to the outside of the garage through the discharge pipe unit; a lifting means for generating a driving force to slide the lifting frame in the vertical direction; a rotation connection member for enabling the suction hole of the suction hood to face an exhaust port of the fire engine while the suction hood rotates around the hinge when the lifting frame ascends by the lifting means; a stopper for stopping a wheel of the fire engine when the fire engine stops while the exhaust port of the fire engine is adjacent to the front side of the upper part of the suction hood; a stop sensor for detecting whether the stopper of the fire engine is stopped; a vehicle sensor detecting whether the fire engine enters the direction of the stopper unit; and a control unit for controlling the operation of the lifting means and the discharge fan in accordance with a signal of the vehicle sensor and the stop sensor or controlling the operation of the lifting means and the discharge fan by a user regardless of the signal of the stop sensor and the vehicle sensor.

A roof vent for a contoured metal surface. The roof vent includes a base or foot having one or more recessed channels that extend between opposing edges of the foot. The recessed channels are sized and shaped to receive correspondingly shaped ridges of the contoured metal roof surface.

Insulation devices, methods and related construction techniques are provided. An exemplary device may include a body having a plurality of openings defining an openwork, to allow the passage of air therethrough when placed in contact with insulation material. The device may further include a plurality of spacer struts and/or spacing depressions fixedly attached to the body. The struts may be configured to maintain a predetermined distance between a first side of the insulation material and a building surface. The body and struts act together to define and maintain a space between the first side of the insulation material and the building surface, for example, for ventilation. The building surface can be the bottom face of a roof, an insulated attic floor, wall sheathing or a soundproofed demising wall, for example. The spacer device can be capable of being transported and stored together with, or as a separate item from, the insulation material, and can also be stored in nested layers. The device can also be stored in rolled form. The openwork of the device can additionally or alternatively include a sheet of entangled net filaments or other similar material.

A roof curb is used in association with a roof flashing installed on a roof with an incline and corrugated ribs, the roof flashing having a base member that may be mounted over a substantially vertical chimney in the roof and a hollow member having a first end and a second end, the first end being larger than the second end and the first end being attached to the base member of the roof flashing. The roof curb includes a first skid and a second skid that may be mounted upon the roof substantially in a direction of the incline and substantially parallel to each other. The first skid and the second skid each have a length that terminates in a top end and a bottom end, each of the first skid and the second skid being tapered such that the bottom end of each of the first and the second skids has a height greater than the top end, the first and the second skids being selectively attached to the roof to bridge the corrugated ribs and the taper being of a gradation to permit attachment of the roof flashing to the roof curb and passage of the substantially vertical chimney therethrough, the roof curb being discrete from the roof flashing.

A building based on a large-space structure body and a freestanding external envelope structure and a construction method, wherein the building comprises a structure body composed of a vertical-structure reinforced concrete member, a reinforced concrete girder and a reinforced concrete slab, and a freestanding combined external envelope system externally hung in a periphery of the structure body; and the structure body is made of a prefabricated combined reinforcement cage member poured with concrete, the prefabricated combined reinforcement cage member is combined and assembled by a prefabricated vertical-structure reinforcement cage member, a prefabricated girder reinforcement cage member and a prefabricated slab reinforcement cage member, and the prefabricated vertical-structure reinforcement cage member is a prefabricated shear wall reinforcement cage member or a prefabricated column reinforcement cage member.

The present invention relates to a cover assembly for a drain and vent pipe. The cover assembly comprises an attaching component, a slide latch, a screen wire, a gasket and multiple tooth configuration. The attaching component is positioned between the screen wire and the slide latch. The screen wire is detachable from the attaching component, thereby enabling easy cleaning and replacement of the screen wire. The slide latch includes the gasket made of silicone rubber, which is extruded into a mold into which the multiple tooth are placed. The multiple tooth grips to an outer surface of the drain or vent pipe, and prevents the cover assembly from sliding off during use. The slide latch is attached to the attaching component at one end and to an outer surface of the drain or vent pipe on the other end.

A portable chimney system includes a trailer having an opening extending into an interior of the trailer. A door is hingedly coupled to the trailer and the door is positionable in a closed position. An awning is removably coupled to the trailer. The awning is selectively positioned on the rear side such that the awning surrounds the opening. The door abuts the awning when the door is positioned in the closed position. A chimney is removably coupled to the awning. The chimney may be fluidly coupled to a stove is positioned within the trailer thereby facilitating the chimney to direct combustion gases outwardly from the trailer.

A water heater heats water with a combustion gas. An exhaust tube includes one end portion and the other end portion, is connected to the water heater at one end portion, and inside thereof is defined as an emission path for the combustion gas. An exhaust pipe is greater in outer diameter than the exhaust tube, and a part of the exhaust tube on a side of the other end portion is introduced in the inside thereof. An exhaust terminal is attached to an end portion of the exhaust pipe and has an exhaust port for exhausting the combustion gas to the outside. An exhaust straightening member is attached to the other end portion of the exhaust tube and has an opening portion for allowing the combustion gas to flow out toward the exhaust port.
