Abstract

The utility model discloses a dark corridor daylighting smoke exhaust structure, include: a plurality of holes are formed on the roof at the top of the dark corridor at equal intervals along the trend of the dark corridor; a concrete flanging structure is poured upwards around each opening; a plurality of lighting and smoke exhausting windows are arranged around each concrete flanging structure; and the top cover structure is arranged at the top of the concrete flanging structure and covers the hole. Thereby solving the problems of lighting and smoke discharge of the corridor in the top layer of the multi-storey building.

Description

Dark corridor lighting and smoke exhausting structure

Technical Field

The utility model relates to a building field especially relates to a dark corridor daylighting smoke exhaust structure.

Background

Common commercial pedestrian street to two-layer commercial building, its bottom is the shop that the four sides were on the street, does not have the interior corridor that needs to discharge fume, and its second floor, and the evacuation corridor that needs two public stair and mutual UNICOM is restricted by the regulation, and when corridor both sides and extreme all arranged the room, the building utilization efficiency was the highest, but its inside evacuation corridor is because unable with building outer wall connection to produce probably the dark corridor that exceeds 20m, has the facility of discharging fume according to the standard needs. The traditional way is for satisfying the corridor requirement of discharging fume, generally has two measures: firstly, sacrificing part of room area, and connecting two sides of the corridor with the outer wall. And secondly, adopting a mechanical smoke exhaust mode. The first case of dark corridors is conventionally unable to meet natural ventilation smoke extraction requirements, and the second case is difficult to use mechanical smoke extraction due to commercial development cost constraints.

Disclosure of Invention

An object of the utility model is to provide a dark corridor daylighting smoke discharging structure solves corridor daylighting and the problem of discharging fume in the multi-storey building top layer.

The technical scheme for realizing the purpose is as follows:

a dark corridor lighting and smoke evacuation structure, comprising:

a plurality of holes are formed on the roof at the top of the dark corridor at equal intervals along the trend of the dark corridor;

a concrete flanging structure is poured upwards around each opening;

a plurality of lighting and smoke exhausting windows are arranged around each concrete flanging structure; and

and the top cover structure is arranged at the top of the concrete flanging structure and covers the hole.

Preferably, the roof on both sides of the dark corridor is sequentially provided with a waterproof layer, a heat insulation layer, a cement mortar layer and a concrete layer from bottom to top.

Preferably, the concrete flange structure comprises from the inside to the outside in sequence: a concrete layer, a waterproof layer and a cement mortar layer;

the top cover structure comprises from the inner side to the outer side in sequence: a concrete layer and a cement mortar layer.

The utility model has the advantages that: the utility model discloses an effectual structural design need not take place the lug connection with the building outer wall, has improved the plane coefficient, reduces the public stand area of building, has increased and has sold the area. The natural smoke exhaust system is adopted under the condition of not being connected with the outer wall, so that the manufacturing cost and later-period operation cost increased by a mechanical smoke exhaust system are reduced.

Drawings

Fig. 1 is a sectional structure view of the dark corridor lighting and smoke exhausting structure of the present invention.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1, the lighting and smoke exhausting structure of the dark corridor of the present invention includes a plurality of holes 200 formed on the roof 1 at the top of the dark corridor 100 at equal intervals along the direction of the dark corridor 100, and a concrete flanging structure 300 is formed around each hole 200 by upward pouring. A plurality of lighting and smoke exhausting windows 400 are arranged around each concrete flanging structure 300, so that the area of the smoke exhausting window meets the lighting and smoke exhausting area requirements of the dark corridor 100. A top cover structure 500 for covering the opening 200 is provided on top of the concrete flange structure 300.

On the roofing 1 of dark corridor 100 both sides, from the bottom up has set gradually waterproof layer 2, heat preservation 3, cement mortar layer 4 and concrete layer 5. Concrete flange structure 300 includes from inboard to the outside in proper order: concrete layer, waterproof layer and cement mortar layer. The roof structure 500 includes, in order from the inside to the outside: a concrete layer and a cement mortar layer.

The present invention is preferably applied to the top floor of a low-rise/multi-rise public building, the space of the lower floor is a large space (such as the whole-floor office or business space) without a public corridor or the space of the lower floor is independently divided into rooms (such as shops) directly facing outdoors, and the present invention can achieve the optimal effect when the top floor needs to be evacuated by the public corridor.

The above embodiments are provided only for the purpose of illustration, not for the limitation of the present invention, and those skilled in the relevant art can make various changes or modifications without departing from the spirit and scope of the present invention, therefore, all equivalent technical solutions should also belong to the scope of the present invention, and should be defined by the claims.
