Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1, a layer of heat insulation board with the thickness of 40mm is added between the steel bracket and the wall body to be used as a heat release bridge base plate. The thermal conductivity and the strength of the thermal-bridge-proof mat meet the technical requirements (K = 0.051W/m) ² K, static bending strength 21.9 MPa). An installation procedure: manufacturing a bracket → processing a heat-proof bridge pad → polishing and cleaning a wall surface → controlling a size of a wall bullet → punching an expansion bolt hole according to the position of the bracket → washing floating dust in the hole or blowing by an air pump → injecting a polyurethane foaming agent and nailing an expansion bolt → installing the heat-proof bridge pad and the bracket → correcting the upper, lower, left and right positions and then screwing the bolt. The method comprises the following specific steps: (1) After the various steel brackets are manufactured, hot galvanizing antiseptic treatment is completely carried out; expansion bolt holes are reserved on the support heat-releasing bridge base plate. (2) The heat-proof bridge pad plate is cut according to the size shown in the figure (generally, the width of each side of the bridge pad plate is 20cm larger than that of the heat-release bridge pad plate of the support)And punching expansion bolt holes on the heat-proof bridge base plate by using an impact electric drill. (3) After the base layer wall surface is qualified according to the relevant quality acceptance standard, the wall surface pops out a size position line from top to bottom according to the elevation position, and an expansion bolt positioning point is determined (note that the outer wall at the position is necessarily a reinforced concrete outer wall). (4) Punching at the positioning point by using an impact electric drill with a corresponding specification, wherein the punching depth is about 5mm deeper than the length of the expansion pipe; the maximum static force after the expansion bolt is installed is influenced by the residue of impurities in the hole, and the impurities and floating dust in the hole are blown out by an air pump (the maximum static force of an M6/8/10/12 expansion bolt is 120/170/320/510 kg respectively). (5) And filling the polyurethane foaming agent into the hole, and installing the expansion bolt in time. (6) And installing a heat-proof bridge base plate and a support, and screwing the nut after correcting the upper, lower, left and right positions.

Referring to fig. 2:1. the pipeline of the overground part is penetrated through the outer wall by penetrating through the pipeline sleeve of the overground outer wall, such as a solar house entrance sleeve and the like. The first procedure is as follows: the structure is reserved with a hole. The hole size is 10cm larger than the diameter of the plastic sleeve. A second procedure: and (5) mounting a PVC plastic sleeve, and foaming between the plastic sleeve and the opening to finish the mounting of the pipeline. A third procedure: and (4) penetrating the pipe, foaming the space between the pipeline and the plastic sleeve, and finally using anti-crack mortar. And (3) troweling and drying the anti-crack mortar on a layer of gridding cloth, then pasting a steam-isolating membrane in the room, and performing a breathable membrane treatment outdoors.

2. The plastic sleeve and the pipeline are concentric, and the plastic sleeve and the pipeline are concentrically positioned by three small wood blocks. Then, the sealing plates on two sides are manufactured by using wood templates and the like, the sealing plates on two sides are attached to two sides of the outer wall, and the two plates are fixed into a whole by using the pull rod. And the gaps among the waterproof sleeve, the plastic sleeve and the pipeline are filled by adopting a field foaming measure, and the foaming requirement is satisfied.

3. After the foaming is finished, the mould is removed (not less than 24 h) after the foaming is completely solidified. And the screw hole of the fixed sealing plate is plugged by the foaming agent. After the air-permeable brick is dried completely, the crack-resistant mortar for leveling, a layer of gridding cloth and the crack-resistant mortar are used for leveling and drying by a wallpaper cutter, then a steam-insulating film is attached indoors, and a breathable film is processed outdoors.

4. Quality control and precautions: (1) when the water stop sleeve is pre-buried, the elevation must be accurate so as to ensure that the plugging material has the annular equal thickness. (2) During foaming, the plugging is tight so as to prevent slurry leakage during foaming, ensure the foaming compactness and smoothness, control the filling amount well and ensure that the compactness and the foaming volume weight are not less than 30kg. (3) The cased pipe does not allow for various joints. (4) After the foaming is finished, the mould is removed after the foaming agent is solidified. Meanwhile, indoor pipeline support fixing needs to be finished, and the sealing performance of the foaming agent is prevented from being disturbed by the pipeline. (5) Construction environment of foaming: if the construction is carried out at a proper temperature, the construction cannot be carried out at a temperature lower than 10 ℃.
