The utility model provides an ancient building roofing construction structures is applicable to and is under construction winter in the north, buries heating element in waterproof layer before the roofing tile, and heating element can generate heat, and compensation tile mortar hydration heat not enough reaches the purpose to the heat preservation maintenance behind the roofing tile.
In a possible embodiment, the waterproof layer 5 comprises a non-slip structure, the heating element is located on the upper part of the non-slip structure, and the cement mortar of the waterproof layer 5 coats the non-slip structure and the heating element. In this embodiment, the waterproof protective layer 5 is prevented from slipping off the roof by providing an anti-slip structure. The waterproof layer serves the purpose of protecting the waterproof layer. The waterproofing layer may comprise a laid up roll of waterproofing material.
In a possible embodiment, the heating assembly is fixed to the anti-slip structure by means of fasteners. Anti-skidding structure and heating element are a body structure, and at 5 in-process of construction waterproof layer, heating element receives the spacing difficult aversion of anti-skidding structure.
In a possible embodiment, referring to fig. 2, the anti-slip structure comprises a steel net 51 laid on the waterproof layer 4, the heating assemblies are distributed along the steel net 51, and the heating assemblies are fixed to the steel net 51 by fasteners.
In this embodiment, the anti-slip structure comprises a steel net 51, and the steel net 51 has a plurality of through holes, so that the heating assembly can be conveniently fixed on the steel net 51. The anti-skid assembly may further include a plurality of cleats 52, each of the cleats 52 being spaced apart from the steel net 51. The cleats 52 may be wood strips.
In one possible embodiment, the heating assembly includes a plurality of heat tracing bands 53, and each of the heat tracing bands 53 is distributed at different positions of the steel net 51.
Electric tracing products are generally classified into: the automatic temperature-limiting heat tracing band 53, the constant-power heat tracing band 53 and the MI mineral cable adopt the two heat tracing principles that current generates heat through a common resistor, and compared with the automatic temperature-limiting electric heat tracing band 53, the two heat tracing principles have larger limitation, the constant-power heat tracing band 53 and the MI mineral cable generate heat stably, the heat generation amount is in direct proportion to the length, the longer the used heat tracing band 53 is, the higher the output power is, the temperature cannot be automatically adjusted along with the change of the external environment, and if a circuit is arranged, the crossed or local excessive density can cause the local temperature of a roof to be overhigh. The self-temperature-limiting heat tracing band 53 can automatically adjust the temperature according to the change of the ambient temperature, so that the maintenance temperature is always kept within a certain range. The present application preferably employs this relatively advanced self-limiting heat tracing band 53.
The self-temperature-limiting electric tracing band 53 is composed of conductive plastics and two parallel busbars with an insulating layer, the conductive plastics are composed of plastic polymers and nano conductive carbon particle mixtures, and when the power supply busbars are electrified, the carbon particles form a circuit between the two power supply busbars and generate heat.
For each electrical trace band 53, the number of conductive paths between the parallel bus bars fluctuates with temperature. When the temperature around the electric tracing band 53 is lowered (cooled), the micro molecules of the conductive plastic shrink to reduce the resistance, so that the carbon particles are connected to form a current-carrying circuit, and the electric tracing band 53 generates heat. When the temperature rises, the conductive plastic expands with micro molecules to increase the resistance, causing the interruption of the power circuit, and the electric tracing band 53 automatically reduces the power output. When the ambient temperature is reduced (cooled), the conductive plastic is restored to the micro-molecular shrinkage state, the carbon material is correspondingly connected to form a circuit, and the heating power of the electric tracing band 53 is automatically increased.
The temperature of the self-temperature-control heat tracing band 53 can be automatically adjusted when the temperature of the mortar is low, and can be automatically adjusted to be low when the temperature is too high, so that the internal temperature is prevented from being too high, the excessive temperature difference between the inside and the outside is avoided, and the generation of cracks can be prevented. Since the temperature of the electric tracing band 53 is automatically adjusted by the self-temperature control, it has advantages that other heat tracing cables do not have, and it does not cause the electric tracing band 53 and the cable itself to be damaged by the over-temperature. For example, DXW-12-J type self-temperature-limiting electric tracing band 53 with a nominal power of 25W/m, a rated voltage of 220V and a surface temperature of 65 ℃ can be selected.
The fastening member includes a band, and each of the heat tracing bands 53 is fixed to the steel net 51 by the band at intervals in a length direction.
Each of the heat tracing bands 53 extends from the lead portion at the edge of the roof structure layer 1 to the inner side of the steel mesh 51, and then extends to different positions to be distributed over the entire surface of the steel mesh 51. The lead position can be determined by the operation field according to the actual environment.
At least part of the heat tracing band 53 of the historic building roofing construction structure is provided with a first extension section 531 and a second extension section 532, the first extension sections 531 of the heat tracing bands 53 are parallel, and the second extension sections 532 of the heat tracing bands 53 respectively extend in a bending way in different directions.
Alternatively, as shown in fig. 2 and 3, the length of the first extension 531 of each heat trace band 53 is gradually reduced in a direction from the middle portion to both sides.
Optionally, one end of each heat tracing band 53 located at the lead part is electrically connected with a junction box, and each junction box is electrically connected with a distribution box. Each first extension section 531 is arranged in a centralized and parallel mode, so that unified wiring is facilitated, and the wiring difficulty is reduced. It should be noted that the junction box is a common fitting for electrically connecting the end of the heat tracing band, and the prior art discloses more, and the structure of the junction box is not described in detail in the present application.
Before actual construction, parameters need to be calculated and selected, specifically as follows:
1. thermal calculation for roof tile maintenance
The coordination among cement heat productivity, covering layer heat dissipation and tracing band 53 electric power is mainly considered in the roof tile maintenance thermal calculation, and the specific calculation refers to the existing specification and a calculation manual. For example: the average minimum temperature at night in one month in Beijing city is-8 ℃, the average maximum temperature in white day is 3 ℃, M10 bagged masonry mortar is selected for roof tiles, the calorific value of cement is ignored, and the temperature of the mortar is not lower than 5 ℃ when the roof tiles are mixed with warm water.
2. Electric power calculation for roof tile maintenance
Covering a cotton quilt with the thickness of 0.03 m after the roof tile is finished, wherein the optimal maintenance temperature of the roof is 20 ℃, the maximum temperature difference between the inside and the outside is about 28 ℃, and the heat conductivity coefficient k of the cotton quilt is =0.04W/m 2 DEG C. (thermal conductivity is the heat transferred in watts/m per 1 square meter area within 1 hour at 1m thickness of material with 1 temperature difference between two surfaces under stable heat transfer conditions 2 DEG C degree
The heat loss per square meter of the tile mortar in the maintenance process is = 0.04X 28 ÷ 0.03=37.3W/m 2 ,
Therefore, the maintenance electric power of the roof tile is 37.3W/m 2 3. And (4) selecting the type and the spacing of the heat tracing band.
The following problems are mainly considered in the heat tracing design selection: according to the technical requirement of roof heat preservation and maintenance, the optimal maintenance temperature is maintained at 20 ℃, and after 7 days of maintenance, the mortar strength can reach the critical strength (not less than 5.0N/mm) 2 ) The use of the heat tracing band 53 may be stopped at this time. Because the maintenance time by using the heat tracing band 53 is short, the maintenance temperature requirement is not high, the technical requirement of maintenance can be met by selecting the low-temperature basic self-temperature-limiting electric heat tracing band 53 in actual construction, and the DXW-12-J self-temperature-limiting electric heat tracing band 53 is selected in the project, the nominal power is 25W/m, the rated voltage is 220V, and the surface temperature is 65 ℃. Considering the adverse factors that the quilt is uneven in thickness and seams, the heat tracing band 53 has a gap to cause uneven heating, and the like, the heat conduction of the heat tracing band 53 has a safety coefficient of 1.2, the heat conduction is 37.3 multiplied by 1.2=44.76 watts, and the value is 45 watts. In order to ensure the maintenance temperature of the tile mortar, the heat quantity led in by the roof heat tracing band 53 per square meter is more than or equal to 45 tiles, and the heat dissipation quantity of the DXW-12-J low-temperature heat tracing band 53 is 25 tiles/meter, so that the electric heat tracing band is required to be used by 45 ÷ 25=1.8 meters per square meter of the roof, and the electric heating band interval is 1 ÷ 1.8=0.55 meters.
After the calculation and selection of the parameters, the installation of the heat tracing band 53 may be performed.
An anti-skid steel mesh is arranged in tile mortar on a ancient building roof, a heat tracing band 53 is bound on the anti-skid steel mesh of a sloping roof by plastic buttons in front of tiles, a threading pipe is not needed, the heat tracing band 53 is used at one time, the tile is electrified and heated after being finished, the roof is covered by cotton quilt, and after the mortar strength reaches critical strength (about 7 days, the mortar strength is not less than 5.0N/mm 2 ) The power supply is cut off and the heat tracing band 53 is left in the roof.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and although the present invention has been disclosed with reference to the above preferred embodiment, but not to limit the present invention, any person skilled in the art can make modifications or changes to equivalent embodiments by utilizing the above technical contents without departing from the scope of the present invention, and any simple modification, equivalent change and modification made to the above embodiments by the technical matters of the present invention are within the scope of the present invention.
