Description

Technical Field

[0001] This utility model relates to the field of building thermal insulation and sound insulation technology, and in particular to a building thermal insulation and sound insulation system. Background Technology

[0002] With the increasing demands for energy-efficient and green buildings, floor insulation and soundproofing systems are being used more and more widely in residential and public buildings. Traditional floor structures often use single insulation materials or simple layered structures, resulting in poor sound insulation performance. Furthermore, during the construction of wire mesh panels, adjacent panels are connected by binding with wire, which is labor-intensive and yields poor connection results. Therefore, this solution provides a building insulation and soundproofing system. Utility Model Content

[0003] The purpose of this utility model is to provide a building insulation and sound insulation system that is simple to operate and improves the thermal insulation and sound insulation effect.

[0004] This utility model is achieved through the following measures:

[0005] A building thermal insulation and sound insulation system is characterized by comprising a plurality of thermal insulation and sound insulation boards disposed on a floor slab base layer, wherein a fine stone concrete protective layer is poured on the plurality of thermal insulation and sound insulation boards, and a plurality of wire mesh is disposed within the fine stone concrete protective layer. In addition, vertical sound insulation sheets are disposed between the thermal insulation and sound insulation boards, the fine stone concrete protective layer and the wall, and around the pipes penetrating the floor slab, and are made of electronically cross-linked polyethylene.

[0006] The specific features of this utility model also include:

[0007] The aforementioned thermal insulation and sound insulation board is an HN thermal insulation and sound insulation board. The HN thermal insulation and sound insulation board uses graphite molded polystyrene board, extruded board, or graphite extruded board as the substrate, and is bonded together with electronic cross-linked polyethylene in the factory using adhesive. It is a composite board with thermal insulation, sound insulation, and vibration damping properties, and is used in building floor thermal insulation and sound insulation systems. Compared with traditional floor structures, it has better sound insulation and other effects.

[0008] Long strips of adhesive tape are provided on all four sides of the upper side of the thermal insulation and sound insulation board. Two-thirds of the width of the adhesive tape is covered with backing paper, and the remaining one-third of the width is adhered to the board, leaving a one-third width gap between the board and the edge. After several boards are aligned and laid out, the backing paper is removed from the adhesive tape on each board. The middle one-third of the tape is then adhered to the gap on the board, and the remaining one-third of the tape extends beyond the board and is then adhered to the gap on the adjacent board. The backing paper on the tape on the adjacent board is then removed and adhered to the already attached tape, further sealing the gaps between adjacent boards and preventing cement slurry from leaking downwards during the compaction of the fine aggregate concrete.

[0009] A circular tape is provided at the top corner of the adjacent thermal insulation and sound insulation board to seal the gaps not covered by the long strip tape.

[0010] Two adjacent wire mesh panels are connected into a whole by a number of clamping mechanisms. The wire mesh panels are made of several cylindrical thin steel wires welded together in a crisscross pattern. The clamping mechanism includes a clamping shell and a clamping core. The clamping shell includes a clamping plate disposed around the thin steel wires on one side of the wire mesh panel. The lower side of the clamping plate is provided with a clamping groove, which passes through the lateral side of the clamping plate away from the corresponding thin steel wire. The clamping core includes an insert plate disposed around the thin steel wires on the adjacent side of the wire mesh panel. The insert plate cooperates with the clamping groove.

[0011] Both sides of the card plate have through holes, and a matching cylindrical pin is movably inserted through the through holes. A circular plate is provided on the outer side of the cylindrical pin. A spring is provided around the cylindrical pin between the circular plate and the card plate end face. One end of the spring is fixed to the circular plate, and the other end of the spring is fixed to the card plate. Both sides of the insertion plate have insertion holes that mate with the inner end of the cylindrical pin. The inner end of the cylindrical pin is inserted into the corresponding insertion hole. When the card core is engaged in the card slot, the cylindrical pin is inserted into the insertion hole under the action of the spring, thus achieving a locking connection.

[0012] The insert plate has a pair of inclined surfaces on its side facing the card plate. The pair of inclined surfaces cooperate with the cylindrical pin and are close to the corresponding insertion hole. When the card case and the card core are engaged, the cylindrical pin can be slid along the inclined surface by squeezing. During the sliding process, the spring is squeezed and finally inserted smoothly into the insertion hole.

[0013] The insert plate has a positioning groove on its side facing the card plate, and the card plate has a corresponding positioning strip. During the process of engaging the card case and the card core, the positioning strip and the positioning groove are first aligned so that the positioning strip is engaged in the positioning groove. At this time, the cylindrical pin will naturally engage smoothly and be inserted into the insertion hole.

[0014] Both the card plate and the insert plate have elongated clamps on the side closest to the thin steel wire. The elongated clamps can be fixed to the card plate or the insert plate by welding. After the elongated clamps are fitted around the thin steel wire, they are fixed by corresponding nuts and bolts. When laying the wire mesh, corresponding card shells and card cores are installed in advance on the outer periphery of the thin steel wires of two adjacent wire meshes. After the laying is completed, the card cores are inserted into the card shells.

[0015] The beneficial effects of this utility model are as follows: This solution is simple to construct and easy to operate. By setting the HN thermal insulation and sound insulation board, the thermal insulation and sound insulation effect is improved. At the same time, the setting of long strip tape makes the sealing effect of the gaps better during construction. In addition, the clamping mechanism makes the connection and fixation between the wire mesh sheets simple and firm. Attached Figure Description

[0027] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0028] Example 1

[0029] See Figures 1-7 A building thermal insulation and sound insulation system includes several thermal insulation and sound insulation boards 1 installed on the floor slab base, a fine stone concrete protective layer poured on the several thermal insulation and sound insulation boards 1, several wire mesh sheets 5 installed in the fine stone concrete protective layer, and vertical sound insulation sheets installed between the thermal insulation and sound insulation boards 1, the fine stone concrete protective layer and the wall, and around the pipes penetrating the floor slab, and made of electronically cross-linked polyethylene.

[0030] The thermal insulation and sound insulation board 1 is the HN thermal insulation and sound insulation board. The HN thermal insulation and sound insulation board is made of graphite molded polystyrene board, extruded board or graphite extruded board as the base material. It is bonded to electronic cross-linked polyethylene with glue in the factory. It is a composite board with thermal insulation, sound insulation and shock absorption properties and is used for building floor and ground thermal insulation and sound insulation systems.

[0031] Long strips of adhesive tape 2 are provided on all four sides of the upper side of the thermal insulation and sound insulation board 1. Two-thirds of the width of the adhesive tape 2 is covered with backing paper 3. The remaining one-third of the width of the adhesive tape 2 is covered with the thermal insulation and sound insulation board 1, leaving a blank area of ​​one-third the width of the adhesive tape 2 between the thermal insulation and sound insulation board 1 and the edge. After several thermal insulation and sound insulation boards 1 are laid in alignment, the backing paper 3 of the adhesive tape 2 on the thermal insulation and sound insulation board 1 is removed. The middle one-third of the width of the adhesive tape 2 is covered with the blank area on the thermal insulation and sound insulation board 1, and the one-third of the width of the adhesive tape 2 extending out of the thermal insulation and sound insulation board 1 is covered with the blank area of ​​the adjacent thermal insulation and sound insulation board 1. Then the backing paper 3 of the adhesive tape 2 on the adjacent thermal insulation and sound insulation board 1 is removed and covered with the already covered adhesive tape 2, thereby further sealing the gap between the adjacent thermal insulation and sound insulation boards 1 and preventing cement slurry from seeping downwards during the vibration of fine stone concrete.

[0032] A circular tape 4 is provided at the top corner of the adjacent thermal insulation and sound insulation board 1 to seal the gaps not covered by the long tape 2.

[0033] Two adjacent wire mesh panels 5 are connected into a whole by a number of clamping mechanisms 6. The wire mesh panel 5 is made of several cylindrical thin steel wires welded together in a crisscross pattern. The clamping mechanism 6 includes a clamping shell and a clamping core. The clamping shell includes a clamping plate 7 set around the thin steel wires on one side of the wire mesh panel 5. A clamping groove 12 is provided on the lower side of the clamping plate 7. The clamping groove 12 passes through the horizontal side of the clamping plate 7 away from the corresponding thin steel wire. The clamping core includes an insert plate 8 set around the thin steel wires on the adjacent side of the wire mesh panel 5. The insert plate 8 cooperates with the clamping groove 12.

[0034] Both sides of the card plate 7 have through holes, through which a matching cylindrical pin 13 is inserted. A circular plate is provided on the outer side of the cylindrical pin 13. A spring 10 is provided around the cylindrical pin 13 between the circular plate and the end face of the card plate 7. One end of the spring 10 is fixed to the circular plate, and the other end of the spring 10 is fixed to the card plate 7. Both sides of the insertion plate 8 have insertion holes 16 that mate with the inner end of the cylindrical pin 13. The inner end of the cylindrical pin 13 is inserted into the corresponding insertion hole 16. When the card core is engaged in the card slot 12, the cylindrical pin 13 is inserted into the insertion hole 16 under the action of the spring 10, thus achieving a locking connection.

[0035] The insert plate 8 has a pair of inclined surfaces 15 on the side facing the card plate 7. The pair of inclined surfaces 15 cooperate with the cylindrical pin 13 and are close to the corresponding insertion hole 16. When the card case and the card core are engaged, the cylindrical pin 13 can be slid along the inclined surface 15 by squeezing. During the sliding process, the spring 10 is squeezed and finally successfully inserted into the insertion hole 16.

[0036] The insert plate 8 has a positioning groove 14 on the side facing the card plate 7, and the corresponding card plate 7 has a matching positioning strip 11. During the process of snapping the card case and the card core together, the positioning strip 11 and the positioning groove 14 are aligned first, so that the positioning strip 11 is snapped into the positioning groove 14. At this time, the cylindrical pin 13 will naturally be smoothly connected and inserted into the insertion hole 16.

[0037] Both the card plate 7 and the insert plate 8 have long strip clamps 9 on the side near the thin steel wire. The long strip clamps 9 can be fixed to the card plate 7 or the insert plate 8 by welding. After the long strip clamps 9 are fitted around the thin steel wire, they are fixed by the corresponding nuts and bolts. When laying the wire mesh 5, the corresponding card shells and card cores are installed in advance on the outer periphery of the thin steel wires of the two adjacent wire mesh 5. After the laying is completed, the card cores are inserted into the card shells.

[0038] Example 2

[0039] Construction process and key points of Example 1:

[0040] 1. Base layer inspection and treatment. The base layer of the floor slab and the wall base at the base of the walls should be cleaned thoroughly, and any protruding objects should be removed to ensure a smooth base layer; leveling treatment may be necessary. The base layer should be dry. Before the construction of the floating floor slab thermal insulation and sound insulation system, a full inspection of the floor slab base layer should be conducted and recorded.

[0041] 2. Mark control lines. Mark horizontal control lines and vertical control lines for the upper edge of the sound insulation sheet on the surface of the wall plaster layer. These lines are used to control the elevation of the fine aggregate concrete protective layer on the floor and the upper edge of the vertical sound insulation sheet. Mark the location lines of the expansion joints of the fine aggregate concrete protective layer on the surface of the cast-in-place floor slab and extend them to the surface of the wall plaster layer. This is used to control the setting of the expansion joints in the protective layer.

[0042] 3. Treatment of indoor and outdoor door openings. For open balconies, entrance door openings (thresholds), and bathroom door openings, fill with fine aggregate concrete to the design height, smooth it, or create a slope.

[0043] 4. Install vertical sound insulation strips. Install vertical sound insulation strips at the base of walls and under pipes penetrating floors. The top of the vertical sound insulation strips should be at least 10mm above the surface of the fine aggregate concrete protective layer, and should be continuously installed at all wall bases and under pipes penetrating floors. The width of the joints between vertical sound insulation strips should not exceed 1mm. After installation, a complete inspection of the installation should be conducted and recorded.

[0044] 5. Laying the thermal insulation and sound insulation boards. The thermal insulation and sound insulation subfloor boards should be laid flat using the dry-laying method, with the joints aligned and the boards perfectly aligned horizontally and vertically. Adjacent thermal insulation and sound insulation subfloor boards should be tightly joined, with a joint width of less than 1mm. The thermal insulation and sound insulation subfloor boards can be cut as needed. After laying, a complete inspection of the laying condition should be conducted and recorded.

[0045] 6. Joint Treatment. Waterproof tape (or sealant applied by brushing or spraying) should be applied to the joints between the thermal insulation and sound insulation pad materials, between the thermal insulation and sound insulation pad materials and the vertical sound insulation sheets, and between the vertical sound insulation sheets. The following requirements should be met:

[0046] 1) The width of the waterproof tape on both sides of the joint should be equal;

[0047] 2) Use a scraper to smooth outwards to remove air bubbles and smooth out wrinkles in the tape. If it is impossible to smooth it out completely, cover and stick a certain length of waterproof tape on the outside to reinforce the seal and prevent cement slurry from seeping in during concrete pouring;

[0048] 3) Apply sealant evenly to the seams by brushing or spraying. For seams with air bubbles or incomplete sealing, apply sealant again to the outside after brushing or spraying.

[0049] 4) No part of the waterproof tape or sealant should be missed when applying it. Before pouring fine aggregate concrete, all waterproof tape or sealant on all joints should be inspected and repaired promptly, and the results should be recorded.

[0050] 7. Laying and binding the wire mesh. The wire mesh should be clean and undamaged. The binding of the wire mesh should comply with the following regulations:

[0051] 1) The overlap width of the mesh panels shall not be less than 100mm (one mesh);

[0052] 2) Use thin iron wire to tie the overlaps. After tying, pay attention to the treatment of the wire ends to avoid the wire ends piercing the thermal insulation and sound insulation pad material and waterproof tape (or sealing interface adhesive) or damaging the hot water floor heating pipe.

[0053] 3) When tying wire mesh using the one-time casting method, spacers, stirrups, and other measures should be used to ensure its vertical position;

[0054] 4) The wire mesh at the expansion joint should be disconnected;

[0055] 5) When hot water underfloor heating pipes are embedded within the fine aggregate concrete protective layer, the lower layer of wire mesh should be laid first, then the hot water underfloor heating pipes should be fixed, and then the upper layer of wire mesh should be laid. The laying and fixing of underfloor heating pipes should comply with the requirements of the "Technical Specification for Radiant Floor Heating" JGJ142 and other relevant standards.

[0056] 6) Before pouring fine aggregate concrete, the binding of all wire mesh sheets should be checked and recorded.

[0057] 8. Install expansion joints. Place polyethylene foam boards or pre-set wooden strips of the same width as the joint at the expansion joint location, and remove them after the fine aggregate concrete protective layer has reached a certain strength.

[0058] 9. The fine aggregate concrete protective layer can be poured in one pour or in two pours. The concrete pouring should meet the following requirements:

[0059] 1) The water-cement ratio should be strictly controlled, and the slump of fine aggregate concrete should not exceed 130mm;

[0060] 2) Mortar spots should be made after the thermal insulation and soundproofing pads are laid;

[0061] 3) During pouring, the transport trolley should not drive directly on the wire mesh and thermal insulation and soundproofing pad material; wooden boards should be laid on it instead.

[0062] 4) When pouring concrete at the base of the wall or where pipes penetrate the floor slab, care should be taken to prevent cement slurry from entering between the vertical sound insulation sheet and the wall.

[0063] 5) During a single pour, there should be special spacers or stirrups under the wire mesh, and the spacing should not exceed 500mm. During the pouring and vibration of concrete, the displacement of the reinforcing bars should be minimized. The position of the wire mesh should be checked and adjusted in a timely manner to ensure that the mesh (the upper mesh in the case of double-layer wire mesh) is in the upper middle part of the fine stone concrete protective layer.

[0064] 6) When pouring concrete twice, the first pour should be about 25mm thick (about 35mm if there is hot water underfloor heating) and then poured. Immediately afterwards, lay and tie the wire mesh, and then pour the second pour, which should be about 15mm thick. The interval between the two pours should not exceed the initial setting time of the concrete.

[0065] 10. Vibrate the fine aggregate concrete, compact, level, and roughen. The concrete can be compacted using a plate vibrator; or rolled back and forth with a 30kg roller until slurry is squeezed out from the surface; low-lying areas should be filled with concrete; after the concrete has slightly absorbed water for 2-3 hours, smooth, polish, and roughen it. Smooth and polish at least twice before final setting.

[0066] 11. Joint Cutting. For floating floor slab insulation and soundproofing systems without underfloor heating, joints should be cut at interior doorways and other locations with significant changes in room dimensions 48–72 hours after the protective concrete layer is poured to release stress. These post-cut joints should comply with the following regulations:

[0067] 1) The fine stone concrete protective layer of the thermal insulation and sound insulation system for the floor with hot water underfloor heating, kitchen floor, and floating floor at the kitchen doorway must not be cut.

[0068] 2) A seam can be cut on one or both sides at the interior doorway;

[0069] 3) The cut should cut through the wire mesh, with a width controlled at 3-5mm and a depth controlled at 15-25mm;

[0070] 12. Curing. After the concrete is smoothed and roughened, cover it with a curing film and sprinkle water. Ensure the film remains moist during curing, watering at least 3-4 times daily, increasing the frequency in summer. The curing time is 7-14 days. People may walk on the fine aggregate concrete protective layer only after its compressive strength reaches 5 MPa. During the curing period, it is strictly forbidden to push wheelbarrows, pile heavy objects, or trample on it.

[0071] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
