Description

The method of floor drain sunk same-layer drainage construction

Technical field

The present invention relates to a kind of construction techniques, the job practices during especially for dwelling house or public works employing same floor wastewater discharge technique.

Background technology

The interlayer drainage pattern is generally adopted in the water discharging under the present domestic dwelling house, and its major defect is: (1) upper strata dirt very easily leaks into down one deck by pipeline, increases the possibility of transmission; (2) maintenance of pipeline and maintenance are carried out in lower floor, disturb resident family of lower floor; (3) concrete floor is destroyed the globality of floor by Durchgangshohle repeatedly, spreads to possibility upstairs when increasing waterproof difficulty and fire; (4) draining noise pollutes big.

Therefore, " Code for design of dwelling houses " (GB50096-1999) 6.1.6 bar regulation: the sewage drainage transverse tube of dwelling house should be located in this layer cover." Code for design of building water supply and sewerage " be 4.3.8 bar regulation (GB50015-2003): the fixture drain of residence toilet should not passing through floors enter his family." healthy residence construction technique main points " (version in 2004) 2.7.4 bar regulation: branch drain should be the boundary with this family.Above clause all requires the residence toilet Drainage Design will adopt co-layer draining.Therefore, in recent years owing to the appearance of the commercial house and the introduction of advanced foreign technology, same floor wastewater discharge technique is very fast in China's development.

At present, the same floor wastewater discharge technique of China mainly contains three kinds: the one, and the body of wall concealed type, the 2nd, the lift slab formula, the 3rd, fall board-like.

Body of wall concealed type co-layer draining belongs to the continent mode of beatting up, and mainly emphasizes tank for excrement pan hiddenly in body of wall, does not generally advocate to be provided with floor drain, and the requirement that this and China washroom must be provided with floor drain is not inconsistent.The ground that lift slab formula co-layer draining need improve the washroom can make the washroom be higher than the ground in room, parlor like this, and not only water is excessive in the meeting, also has the inconvenient problem of the elderly's action.Can satisfy the co-layer draining requirement simply though fall board-like co-layer draining, need to increase cost, increase loading, waterproof quality to civil engineering requires also than higher, when design, must consider the drainage problem of caisson, otherwise may form reservoir, cause the difficulty of maintenance.

Summary of the invention

At the defective that existing co-layer draining job practices exists, the invention provides a kind of be used for geothermal heating system formula dwelling house plate does not fall, lift slab is not provided with the co-layer draining method of floor drain.

Solving the problems of the technologies described above the concrete technical measures of being taked is: a kind of method of floor drain sunk same-layer drainage construction is characterized in that: adopt the hidden water tank type toilet of back draining; Under the prerequisite that guarantees slope requirement, the end face of side floor drain (1) is equal with ceramic tile layer end face or a little less than ceramic tile layer end face, it below the ceramic tile layer geothermal layer, it below the geothermal layer floor end face, the sinking inlet part of floor drain is between floor end face and floor bar, the degree of depth of sinking to imbedding is equal to or greater than the floor drain height minus and removes the geothermal layer height, reduces the ceramic tile layer height again, adds the slope height; Sinking method is dewatering horizontal tube and side floor drain direct burial sinking construction method or dewatering horizontal tube and side floor drain mould sunk type job practices.

Beneficial effect of the present invention:

The specific embodiment

Accompanying drawings job practices of the present invention.

The principle of floor drain sunk same-layer drainage construction method: in order to satisfy the demand of co-layer draining, floor drain used among the present invention adopts the side dewatering type, and Fig. 1 illustrates a kind of side dewatering type floor drain.Wherein, arrow is represented the direction of current; A is water main inlet port (drain cover), and water main inlet port during actual installation (drain cover) is equal with ground or a little less than ground; B is secondary water inlet, is used for being connected with the sewer pipe of washbasin or washing machine, to replenish the water seal water of floor drain 1 at any time; C is a delivery port, is connected with soil stack 7 through dewatering horizontal tube 5; H1 is the height of floor drain 1, and because of the model difference, it highly also has different, generally between 60～210mm, and the common 110mm that is of a size of.

Utilize " geothermal layer has the thickness more than 50 millimeters at least " this advantage, the part of side floor drain housing and dewatering horizontal tube is sunk to imbedding in the floor, Fig. 2 is the size relationship figure of floor, geothermal layer, ceramic tile layer.Among the figure, 2 is floor, and its thickness is generally 100～180mm, and present northern residential houses is got 120mm mostly, by propping up template earlier, pricks and ties up reinforcing bar, and the method for last concreting forms.Reinforcing bar generally is positioned at the bottom of floor.For not influencing floor strength, generally speaking, the sinking of floor drain is imbedded size and should be reduced above the reinforcing bar to the thickness of soffit less than total floor thickness, that is to say that the bottom surface of floor drain can not be lower than steel bar layer.

Underground heat is the heating mode that generally adopts in the north in recent years.Normally at floor 2 upper berth one deck thermal reflecting coatings, dish ground heat pipe on thermal reflecting coating, cobble is spilt in the shop, gap of ground heat pipe, uses cement mortar screeding again, thereby forms the above geothermal layer 3 of 50mm at least.At geothermal layer 3 upper berth mortar cement, sticking brick forms the ceramic tile layer 4 of about 20mm.For ease of construction, the position of placing floor drain should not lay the ground heat pipe.

Complex chart 1 and Fig. 2: the height h1 of floor drain 1 is 120mm, and the thickness h 3 of geothermal layer 3 is 60mm or greater than 60mm, the thickness h 4 of mortar ceramic tile layer 4 is 20mm; When floor drain 1 when the distance of standpipe 7 is not more than 1m, the high h5 of the gradient is 20mm.

Difference in size after the height h4 addition of the size after floor drain height h1, the high h5 addition of the gradient and the thickness h 3 of geothermal layer 3, mortar ceramic tile layer 4 is: (h1+h5)-(h3+h4)=(120mm+20mm)-(60mm+20mm)=and 60mm; If this 60mm that differs is sunk in the floor, or sinking size h6 is greater than more than the 60mm, then: h3+h4+h6 〉=h1+h5, thus satisfied the requirement for height that floor drain is installed.Because the thickness of floor is more than 120mm, the shape of floor drain is that the diameter of the first half is thick, the diameter of Lower Half is thin, so, the floor drain that the diameter at a sinking position is not more than 100mm sinks to imbedding 60mm at most, with the pipeline of the DN50 30mm that sinks at most, can ignore to the intensity effect of floor.

Embodiment 1
