4.3   工法要点

4.3 main points of industrial law

4.3.1施工准备：

4.3.1 construction preparation:

4.3.1.1将散热器抬到试压台上，连接试压泵，打开进水阀门，往散热器内充水，同时打开放气嘴，排净空气，待水满后关闭放气嘴。

4.3.1.1 will be carried to the radiator on testingtable, connect the pressure test pump, open the inlet valve to the radiator with water and open the vent mouth, exhaust air, water to be full closed after discharge nozzle.

4.3.1.2加压到规定的压值后，关闭进水截门，持续2-3min，观察散热器接口板壁阀门有无渗漏，不渗漏为合格。

4.3.1.2 pressure to the specified pressure after closing the water inlet valve, duration 2-3min, observation of radiator valve has no leakage wall interface, no leakage for qualified.

4.3.1.3如有渗漏视情况修理或更换，试压合格后打开泄水阀门，泄净水后将散热器运到安装地点安装。

4.3.1.3 if there is leakage, repair or replace, test the pressure after opening the discharge valve, discharge the water after the radiator to install the installation site.

4.3.2按照设计图纸要求将符合设计规格的散热器运到各房间，根据散热器的尺寸、安装位置及高度在墙上画出安装中心线。

4.3.2 according to the requirements of the design drawings, the radiator that meets the design specifications is transported to the rooms. The installation center line is drawn on the wall according to the size, location and height of the radiator.

4.3.3托钩和固定卡安装：

4.3.3 hook and fixed card installation:

4.3.3.1按设计及规范要求在要安装散热器的墙上画出散热器托钩安装的中心线位置。

4.3.3.1, according to the design and specification requirements, draw the center line of the radiator hooked hook on the wall of the radiator to be installed.

4.3.3.2用錾子或冲击钻等在墙上按画出的位置打孔洞，固定卡孔洞深度不少于80mm（使用膨胀螺栓应按膨胀螺栓的要求深度），打好孔洞将托钩栽好固定。

4.3.3.2 with a chisel or percussion drill on the wall to draw the location of holes, fixing hole depth of not less than 80mm (the use of expansion bolts should be according to the requirements of the depth of the expansion bolt), lay the holes to support hook fixed planting.

4.3.3.3每组钢制板式散热器背板上均在四角焊上带孔的钢板支架，而后将散热器安装在墙上的固定支架上（也可以按照厂家配套的托钩进行安装）。

4.3.3.3 each group of steel plate radiator backplane is welded with steel plate support with holes on the four corners, then the radiator is installed on the fixed support on the wall (also can be installed according to the supporting hook matched by the manufacturer).

4.3.3.4在轻质板墙上，钩卡用穿通螺栓加垫圈固定在墙上，并且保证垫片不能高出装饰墙面。

4.3.3.4 is on the wall of light plate. The hook card is fixed on the wall with a perforated bolt and a washer, and ensures that the gasket cannot be high out of the decorative wall.

4.3.4散热器挂装：将采暖管路冲洗干净后，把钢制板式散热器抬起挂在固定支架上，散热器背面与装饰后的墙内表面安装距离要符合设计或产品说明书要求，如设计未注明，应为30mm。带上垫圈和螺母，紧到一定程度后找平找正，然后拧紧到位。

4.3.4 radiator installation: after heating the heating pipeline, the steel plate radiator is lifted up and hung on the fixed support. The distance between the back surface of the radiator and the interior wall of the decoration must meet the requirements of the design or product specification. If the design is not specified, it should be 30mm. Take the washer and nut, tighten to a certain degree and look for the correct, then tighten it in place.

4.3.5钢制板式散热器的放风门按设计要求由厂家负责配套安装好。

4.3.5 steel plate radiator at the door according to the design requirements by the manufacturers responsible for supporting the installation.

4.3.6支管安装：

4.3.6 branch installation:

4.3.6.1侧进侧出式板式散热器支管安装：分为同侧连接、异侧连接和下进下出异侧连接三种连接方式（如上图所示）。同侧连接方式适用于各种型号的散热器；异侧连接适用于有较大结构长度的散热器，使整个长度能均匀散热；采用下进下出异侧连接方式散热能力要降低10%，因此不建议采用此连接方式。支管由采暖立管甩口位置连接支管至散热器，坡度为1%，坡向利于排气和泄水。

4.3.6.1 side inlet and outlet side plate radiator tube installation: it can be divided into three connection ways: one side connection, opposite side connection and down inlet and outlet side side connection (as shown above). The way of the same side connection is suitable for all kinds of radiator. The opposite side connection is suitable for the radiator with larger structure length, so that the whole length can be evenly dissipating. The heat dissipation ability of the lower down outlet and the opposite side connection mode is reduced by 10%, so it is not recommended to use this connection mode. The branch pipe is connected with the branch pipe to the radiator by the position of the heating riser. The slope is 1%. The slope is favorable to the exhaust and discharge.

4.3.6.2下进下出式板式散热器支管安装：下进下出式散热器支管多数都是塑料或复合采暖管道埋地敷设，在相应位置甩口出地面垫层用钢塑转换接头换金属管与散热器连接，因为下进下出散热器进出口支管过短，尺寸无法调整，支管与散热器接口对接困难，为便于安装，采取在散热器接口处地面预留200mm*300mm管槽的方法，利用塑料管道的柔性保证金属管与散热器接口正常对接（详见散热器支管连接大样图）。支管连接完成后将预留的管槽填实，填堵管沟时要派专人看管散热器支管，防止施工过程中将支管偏离原位，使露出地面的金属管道保持垂直，垫层混凝土凝固后，土建可以进行面层的施工。

4.3.6.2 in and out in the bottom plate type radiator pipe installation: in a branch type radiator is mostly plastic or composite heating pipes buried in the corresponding position, a ground cushion with swing steel plastic adapter for metal tube connected with the radiator, because in and out the radiator import and export branch is too short, can not adjust the size. Docking branch pipe and radiator interface difficulties, in order to facilitate the installation, take in the radiator at the interface of ground 200mm*300mm tube slot reservation method, using the flexible metal tube radiator and ensure normal plastic pipe butt joint interface (see heat exchanger branch connection drawing). After the completion of branch connection will be reserved for the pipe filled, filling pipe ditch to send someone to look after the radiator pipe, to prevent the construction process will deviate from the branch in situ, the metal pipe above the ground to keep vertical bedding concrete construction can be solidified, the surface layer.

4.3.7采暖系统安装完毕，按照设计及规范要求进行系统水压试验，发现渗漏及时处理，直至试压合格。

4.3.7 heating system is installed, according to the design and standard requirements of the system water pressure test, found that the leakage of timely treatment, until the test pressure is qualified.
