居家地暖工程施工技巧

Construction techniques of home heating project

1、 施工准备（含清理地面)→安装固定分、集水器→铺设绝热板和边界膨胀带→地暖反射膜→铺设盘管（PEX、PERT、PB等） ：加热盘管铺设的顺序是从远到近逐个环圈铺设，凡是加热盘管穿地面膨胀缝处，一律用膨胀条将地面分隔开来，加热盘管在此处均须加伸缩节，伸缩节为加热盘管专用伸缩节，其接口连接以加热管品种确定。施工中须由土建与安装事先划分好→设置过门伸缩缝（含盖钢丝网）→中间验收（一次水压试验）→回填细石混凝土层→完工验收（二次水压试验 ）。（专用温控器最后安装）竣工结束时，绘制图纸，准确标注盘管位置和地温传感器的埋设地点。

1, construction preparation (including cleaning ground) - Installation of fixed points, water collector, adiabatic plate and boundary expansion belt, floor heating reflecting film and paving coil (PEX, PERT, PB, etc.): the order of heating coil laying is to lay from far to near ring ring. Apart from this, the heating coil units must be provided with expansion joints. The expansion joint is a special expansion joint for heating coil units, and the interface connection is determined by the variety of heating pipes. In the construction, the construction and installation must be divided in advance - setting up the expansion joint of the door (including the cover wire mesh) - the intermediate acceptance (one water pressure test) - backfilling the fine stone concrete layer and the completion acceptance (the two water pressure test). (final installation of the special thermostat) at the end of the completion, draw up the drawings, accurately mark the location of the coil and the location of the ground temperature sensor.

2、卫生清理，建筑垃圾及灰尘

2. Sanitary cleaning, construction waste and dust

3、绝热层的铺设：

3. The laying of the adiabatic layer:

铺设绝热层的地面应平整、干燥、无杂物。墙面根部应平、直且无积灰现象。绝热层的铺设应平整，绝热层相互间的接缝应严密。直接与土壤接触的或有潮气侵入的地面，在铺放绝热层之前应先铺一层防潮层。

The ground should be flat, dry and free of sundries. The root of the wall should be flat, straight and without ash accumulation. The insulation layer should be laid flat and the joints between the insulation layers should be tight. A soil moisture barrier should be laid on the ground that is directly in contact with the soil or with moisture intrusion.

重视边角隔热层的设置和就位

伸缩缝的设置：

The setting of the expansion joint:

1. 在与内外墙、柱及过门等交接处应敷设不间断的伸缩缝，伸缩缝连接处应采用搭接方式，搭接宽度不小于10mm；伸缩缝与墙、柱应有可靠的固定方式，与地面绝热层连接应紧密，伸缩缝宽度不宜小于20mm。伸缩缝宜采用聚苯乙烯或高发泡聚乙烯泡沫塑料。

1. in the junction with internal and external walls, columns and doors and other joints should be laid uninterrupted expansion joints, expansion joints should be connected to the joint way, lap width is not less than 10mm; expansion joints and walls, columns should be reliable fixed mode, connected to the ground floor insulation, expansion joint width should not be less than 20mm. Expansion joints should be made of polystyrene or high foamed polyethylene foam.

2. 当地面面积超过30㎡或边长超过6m时，应按不大于6m间距设置伸缩缝，伸缩缝宽度不小于8mm（一般工地我们做10mm）。伸缩缝宜采用高发泡聚乙烯泡沫塑料或内满填弹性膨胀膏。

2. when the surface area is more than 30 or more than 6m, the expansion joint should be set at the distance of no more than 6m, and the width of the expansion joint is not less than 8mm (general site we do 10mm). Expansion joints should be made of high foamed polyethylene foam or filled with elastic expansion paste.

3. 伸缩缝应从绝热层的上边缘到填充层的上边缘整个截面上隔开。

3. the expansion joint should be separated from the upper edge of the insulation layer to the upper edge of the filling layer and the entire section.

5、卫生间施工 ：

5. Toilet construction:

卫生间应做两层隔离层，作法可参见《低温热水地面辐射供暖技术规程》附录 A。

The toilet should be made of two layers of isolation layer. The method can be seen in Appendix A of the technical specification for low temperature hot water floor radiant heating.

卫生间过门处应设置止水墙，在止水墙内侧应配合土建专业作防水，以防止卫生间积水渗入绝热层，并沿绝热层渗入其它区域。加热管穿止水墙处应设防水套管，防水套管两端应加密封。

The water stop wall should be set at the door of the toilet. In the inner wall of the water stop wall, the waterproofing should be combined with the civil engineering specialty to prevent the water from seeper into the insulation layer and infiltrate into other areas along the adiabatic layer. Waterproofing sleeves should be installed at the wall of the heating pipe through the watertight wall, and the ends of the waterproof bushing should be sealed.

做完防水闭水试验并经过验收。

Finish the water proof and closed water test and pass the acceptance.
