Description
Technical field
The invention belongs to construction engineering technical fields, relate generally to building sloping roof structure and its method of construction.
Background technology
The roofing in house is roughly divided into two class of pitched roof and flat roof deck.In China's conventional house building, pitched roof building
Very favored by people always.Traditional pitched roof building is first to set up house beam, then sets up roof slope roof truss, then in room
Under tile and cover tile are laid on upper frame.This traditional roof structure is very easy to be impaired, and tile is easy to be started by strong wind or by hard object
It smashes, wind resistance anti-disaster ability is poor, once tile damages or falls, house will fill wind roof leaking, need often to repair.In addition its
Poor sealing, heat-resisting and winter resistance are all poor.Into the modern times, people start directly to pour into a mould pitched roof using armored concrete,
Although wind resistance anti-disaster ability and leakproofness are improved, the aesthetic feeling on traditional tile top is lost completely, and its is heat-resisting and anti-
Cold still poor, summer is sultry within doors, and winter is cold.More major problem is that, since cement mortar is not corrosion-resistant and antidetonation
, often there is the problems such as roofing splits, falls off, leaking, it is often necessary to repair in use in the characteristics such as property is poor.In addition, raining
When, rainwater leaves along pitched roof, completely sinuous flow, brings inconvenience to people.Although someone, which takes to set up in eaves, connects rain slot, by rain
Water introduces downpipe, but this exposed beauty for connecing rain slot and seriously affecting building by connecing rain slot, also often due to sealing
It is not in place to lead to leak, often to repair.
Invention content
It is an object of the present invention to solve the deficiency of the existing technology and provide a kind of stabilized structure, attractive and durable, heat-insulated effects
Fruit is good and can effectively converge house pitched roof and its method of construction that rainwater recycles.
The purpose of the present invention is achieved through the following technical solutions：
A kind of structurally stable heat-isolating antiseepage pitched roof is included the sloping roof poured using armored concrete, is layed in
The light steel keel support of roofing, the roofing tile being laid on lightgage steel joist frame；The light steel keel support includes along the slope of roof
Be spaced installation the main joist being mutually parallel, arranged for interval be welded on main joist and with the orthogonal secondary joist of main joist,
It is mutually aligned the fixed block that interval is welded on every secondary joist；The roofing tile includes between riding upon two fixed blocks from room
Eaves bottom sequence is laid with to the under tile at the top of roofing, sequence and is laid with cover tile of the buckle closure on adjacent two-way under tile and fixed block；?
The roofing pours recessed hidden eaves gutter close at root edge, is located at main joist in roofing and secondary joist junction is embedded with
Steel bar end, the main joist and/or secondary joist are welded with steel bar end, and the under tile is installed on by connecting bolt on secondary joist；
Scupper is offered on the upward slope under tile close to hidden eaves gutter, falling of being communicated with eaves gutter is provided at both ends in hidden eaves gutter
Rain pipe.
Roofing of the present invention include armored concrete pouring layer and the cement mortar screeding layer being successively laid with, waterproof layer,
Waterproof roll layer, insulating layer, cement mortar protective course.
Steps are as follows for the method for construction of structurally stable heat-isolating antiseepage pitched roof of the present invention：
Being poured Step 1: completing sloping roof using armored concrete, when pouring under roofing eaves and building masonry wall
Intersection formwork pours hidden eaves gutter, and embedded bar head is arranged in a matrix in roofing；
Step 2: being laid with light steel keel support in roofing；It first is laid with main joist along the slope of roof, then on main joist laterally
Secondary joist is welded, then interval is welded and fixed block on every secondary joist, and the fixed block on every secondary joist is mutually aligned to be formed
Multichannel fixed block；Finally main joist and steel bar end are welded, light steel keel support is fixed；
Mat formation Step 3: carrying out tiling, under tile is sequentially laid between two fixed blocks along longitudinal direction by column, using connection
Bolt passes through under tile and secondary joist, and under tile is installed and is fixed, and cover tile sequence is then laid with buckle closure in adjacent two-way under tile and solid
Determine on block；Close to hidden eaves when opening up scupper under tile at the upward slope close to hidden eaves gutter, or being laid under tile
It is laid at the upward slope of ditch to have opened up the under tile of scupper；
Step 4：The pipe that rains communicated with eaves gutter is set at hidden eaves gutter both ends, or in hidden eaves gutter both ends ditch
Bottom opens up water falling hole, and the pipe that rains is set up under water falling hole.
After the completion of the reinforced concrete roof of above-mentioned steps one pours, successively in roofing topping laying cement mortar screeding
Layer, waterproof layer, waterproof roll layer, insulating layer, cement mortar protective course.
The present invention is fixed on light steel by the way that light steel keel support is firm on roofing, by under tile by connecting bolt
On keel bracket, the firm installation of under tile is realized, will not loosen and be scattered.By in reinforced concrete roof close at root edge structure
Hidden eaves gutter is built, and opens up scupper on the upward slope under tile close to hidden eaves gutter, the rainwater that retention roofing flows down simultaneously draws
Enter eaves gutter, rainwater enters the pre-buried pipe that rains in eaves gutter end by hidden eaves gutter, through rainwater down pipe in-line arrangement to rain water collecting system
It is interior, it realizes rainwater cycling and reutilization, avoids and cause a large amount of ponding of roofing on most of rainwater catchment to roof boarding and drip to wear
The case where stone damage roofing, occurs.In addition, being played very there are certain overhead space between reinforced concrete roof and tiling
Good heat-blocking action, can make house indoor more comfortable.The eaves gutter of hidden, which designs, makes row's rain system hidden under tiling, right
Facade does not influence completely.
Sloping roof structure that the present invention is built is light and handy and firm stable, is unlikely to deform, will not fall off, and has anti-high wind, anti-
Shake ability is strong, the outstanding features such as heat-insulated, good seepage-proof property.The method of construction simple process of pitched roof of the present invention, it is quick for installation, build
Make at low cost, construction safety.
