Description

Technical Field

[0001] The present invention relates to the technical field of precast floor production and construction, and specifically relates to a construction method of a sound-insulating floor facilitating the routing of water and electricity and the installation of floor heating. Background Art

[0002] Precast and assembled buildings are precast component products for assembling and building houses in an industrialized way of producing products on an assembly line. Such precast and assembled buildings can effectively improve the production and construction efficiency of buildings and can also effectively reduce the damage to the surrounding environment during production and construction; in addition, since they are precast components, components with different strengths and thicknesses can be provided according to the construction requirements of different buildings to meet the construction requirements of the buildings. According to the main structural forms of the buildings, they can be divided into: panel assembly types, such as large-panel buildings; box assembly types, such as reinforced concrete box buildings, wooden box buildings, etc.; frame assembly types, such as reinforced concrete skeleton precast buildings, light steel precast buildings, and light wood structure buildings, etc. For precast and assembled residential buildings, currently the relatively popular one is the reinforced concrete skeleton precast building.

[0003] Existing residential buildings are mainly high-rise residential buildings, and the number of households in a building can reach hundreds. If so many people live in the same building and the sound insulation effect between floors is poor, it will have a greater impact on the quality of life of the people in the building. Therefore, as people's requirements for the quality of life continue to increase, in actual life of residential buildings, the requirements for the sound insulation effect are also getting higher and higher. The sound insulation between different floors is closely related to the sound insulation effect of the floor slab. In current residential buildings, the construction related to floor slab sound insulation is carried out by the owners with sound insulation requirements inside their own houses during the decoration period. Since not all owners in the building carry out the construction of sound insulation during decoration, when only individual owners carry out the construction of sound insulation inside their own houses, the sound insulation effect cannot reach the ideal effect.

[0004] In addition, with the popularization of floor heating, floor heating has gradually become the preferred way of heating in people's lives in most parts of the country. The installation of floor heating is also installed by the owners during decoration. Due to the different technical levels of different decoration companies and different construction workers, and the different floor heating materials and material qualities selected, the effects of the installed floor heating and the quality of the installation construction are uneven, resulting in uneven heating effects achieved by central heating. Even the installation construction with poor quality and the relatively low-quality materials selected will cause the water in the floor heating pipes to seep out from the pipes, resulting in floor slab seepage, which not only affects the owner's own house but also affects the neighbors on the lower floor or next door. Moreover, the repair construction is complex, the construction period is long, and the construction cost is high.

[0005] It is known to those skilled in the art that it is most convenient to route the water and electricity pipelines in a house through the ground, and the amount of pipe materials used is the least. However, the pipeline routing in currently built residential buildings generally goes through the walls. This is because the water connection interfaces in the current houses basically only lead to the kitchen and the bathroom, and the water pipelines in the remaining positions in the house need to be modified by the owners during the decoration. The circuit also only leads a lighting circuit and a socket circuit from the distribution box to each room through wire pipelines, and the remaining circuits also need to be modified by the owners. During the process of modifying the above water and electricity pipelines, the owners will inevitably damage the ground of the house they purchased. To ensure construction safety, during the construction of the building, the water and electricity pipelines are not routed through the floor slab but only through the wall.

[0006] Therefore, researching a precast floor slab that can facilitate the pre-routing of water and electricity pipes, effectively has a sound insulation effect, and is also convenient for the construction and heat conduction of the floor heating, so as to overcome the above technical problems and change the previous technical habits, is a relatively new technical direction in this field. In addition, it is necessary to take into account the strength of the floor slab and reduce the decoration cost of the owners during the later decoration, and propose a set of precast floor slab structures and corresponding production methods as well as precast floor slab structures and corresponding construction methods. Summary of the Invention

[0007] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a construction method for a sound-insulating floor slab that facilitates the routing of water and electricity and the installation of floor heating. It can complete the construction quickly by assembling on the construction site, and can directly embed pipelines according to the water and electricity pipelines in the floor slab and lay the floor heating, thus improving the production efficiency and shortening the production cycle. Moreover, the top surface of the floor slab is directly constructed to the surface decoration layer, so that during the subsequent decoration of the owners, there is no need to modify the ground and no need to damage the ground, shortening the decoration cycle.

[0021] A further improvement of the present invention is that in step c), when both the connection layer and the water and electricity wiring layer are poured with coarse sand concrete, the connection layer and the water and electricity wiring layer are poured simultaneously; when the connection layer is poured with coarse sand concrete and the water and electricity wiring layer is poured with medium sand concrete, first pour the connection layer, and then pour the water and electricity wiring layer after the concrete of the connection layer has solidified.

[0040] The part of the connecting rod A6 extending out of the concrete base layer 2 is wound into a spiral part 9, and one end of the connecting rod A6 far from the concrete base layer 2 is wound to be parallel to the plate surface of the precast floor slab body 1.

[0041] A connecting plate 10 parallel to the plate surface of the precast floor slab body 1 is fixedly arranged at the edge of the side wall of the core plate 3 corresponding to the length direction of the concrete base layer 2. The connecting plate 10 extends outwards from the side wall of the concrete base layer 2 in the length direction, and the connecting rod B7 is fixedly connected to the edge of the connecting plate 10 away from the concrete base layer 2.

[0042] A strip-shaped through hole 11 is arranged along the length direction of the connecting rod B7.

[0044] The part of the core plate 3 corresponding to the inside of the concrete base layer 2 is a mesh plate with a plurality of flow holes evenly distributed.

[0045] Reinforcement layers 22 parallel to the plate surface of the precast floor slab body 1 are respectively fixedly arranged in the sound-insulating concrete layer A4 and the sound-insulating concrete layer B5. The reinforcement layers 22 are respectively fixedly connected to the core plate 3 through a plurality of connecting vertical rods 23, and the connecting vertical rods 23 are perpendicular to the plate surface of the precast floor slab body 1.

[0046] The connecting vertical rod 23 fixed to the sound-insulating concrete layer A4 is fixed at the wave crest position of the corrugated plate of the core plate 3, and the connecting vertical rod 23 fixed to the sound-insulating concrete layer B5 is fixed at the wave trough position of the corrugated plate of the core plate 3.

[0047] The connecting vertical rod 23 is a connecting bolt, and the connecting bolt respectively fixes and connects the corresponding positions of the core plate 3 and the reinforcement layer 22 through nuts 24.

[0048] A method for producing the precast sound-insulating floor slab as described above includes the following steps:

[0049] 1) First, the flat blank plate of the core plate 3 with a plurality of flow holes evenly distributed is cut and processed, so that a plurality of connecting rods B7 are symmetrically formed at both edges in the length direction of the flat blank plate, and a plurality of connecting rods A6 are symmetrically formed at both edges in the width direction;

[0050] 2) Then, the connecting rod B7 of the cut flat blank plate is drilled to form a strip-shaped through hole 11;

[0051] 3) Next, the connecting rod A6 is screwed to form a spiral part 9;

[0052] 4) Then, the flat blank plate is molded to form a corrugated plate with a corrugated structure evenly arranged in sequence along the width direction of the flat blank plate, and flow holes are provided at both the wave crest and wave trough of the corrugated plate;

[0053] 5) Then tie up the reinforcement layer 22 of the sound-insulating concrete layer A4, place the reinforcement layer 22 of the sound-insulating concrete layer A4 directly above the core plate 3, and make the reinforcement layer 22 match the corrugated plate of the core plate 3. Then mark the positions of the circulation holes at the wave crests of the corrugated plate corresponding to the reinforcement layer 22;

[0054] 6) Then pass the connecting bolts upward through the reinforcement layer 22 from the bottom of the marked position of the reinforcement layer 22 of the sound-insulating concrete layer A4, and fix the ends of the connecting bolts to the reinforcement layer 22 with nuts 24;

[0055] 7) Then add the mixed and stirred sound-insulating concrete into the rectangular groove casting mold, and scrape the top surface of the sound-insulating concrete to be horizontal. Then, when the top surface of the sound-insulating concrete is at the upper part of the rectangular groove casting mold, place the reinforcement layer 22 of the sound-insulating concrete layer A4 fixed with connecting bolts on the top surface of the sound-insulating concrete, and continue to add the mixed and stirred sound-insulating concrete into the rectangular groove casting mold. After scraping the top surface of the sound-insulating concrete to be horizontal again, make it higher than the top of the reinforcement layer 22 in the rectangular groove casting mold;

[0056] 8) During the solidification process of the sound-insulating concrete layer A4, pass the connecting bolts upward through the circulation holes at the wave troughs of the corrugated plate of the core plate 3, thread the nuts 24 on the upper parts of the connecting bolts passing upward through the circulation holes at the wave troughs, and horizontally place the reinforcement layer 22 of the sound-insulating concrete layer B5 on the connecting nuts 24. The connecting bolts passing through the circulation holes at the wave troughs continue to pass upward through the reinforcement layer 22 of the sound-insulating concrete layer B5 and then thread another connecting nut 24, so that the reinforcement layer 22 of the sound-insulating concrete layer B5 is clamped and fixed by the upper and lower connecting nuts 24;

The wide-side heightening side plate is provided with matching connection holes corresponding to the spiral part 9, and the connection holes are hermetically connected to the spiral part 9;

[0097] When both the connection layer 16 and the water and electricity wiring layer 15 are poured with coarse sand concrete, the connection layer 16 and the water and electricity wiring layer 15 are poured simultaneously; when the connection layer 16 is poured with coarse sand concrete and the water and electricity wiring layer 15 is poured with medium sand concrete, the connection layer 16 is poured first, and after the concrete of the connection layer 16 solidifies, the water and electricity wiring layer 16 is poured;

[0098] When the water and electricity wiring layer 15 is poured, the top surface of the concrete is scraped by a scraper to make the top surface of the entire floor slab in the same horizontal plane;

[0100] d) After the connection layer 16 solidifies, immediately remove the formwork corresponding to the connection layer 16 and remove the support members below the construction floor slab.

[0101] After removing both the formwork corresponding to the connection layer 16 and the support members below the precast floor slab body 1 of the construction floor slab, then remove the protective cushion layer B on the bottom surface of the sound insulation concrete layer A4 of the precast floor slab body 1 of the construction floor slab, and construct the decorative layer of the wall and the decorative layer of the ceiling inside the building below the construction floor slab.

[0102] After the concrete of the water and electricity wiring layer 15 solidifies, remove each formwork in step c), and then sequentially lay and fix the cement fiber board 17 on the top of the water and electricity wiring layer 15;

[0103] Both between the cement fiber board 17 and the water and electricity wiring layer 15 and between adjacent cement fiber boards 17 are fixedly connected by cement mortar.

[0104] After the cement fiber board 17 is laid, the top surface of the cement fiber board 17 is leveled by self-leveling of horizontal mortar.

[0105] e) After the cement fiber board 17 is fixed, then lay and fix the floor heating reflective film 19 on the top surface of the cement fiber board 17;

[0108] g) After the concrete of the floor heating laying layer 20 solidifies, then construct the surface decoration layer 21 on the top surface of the floor heating laying layer 20, thereby completing the installation of this layer of floor slab.

[0109] The surface decoration layer 21 is any one or more of laid floor tiles, floors or stone slabs, or the surface decoration layer 21 is a terrazzo layer or a floor cushion layer;

[0110] h) Lay the protective cushion layer A on the top surface of the surface decoration layer 21, and repeat the above steps on the floor slab where the protective cushion layer A is laid to carry out the construction of the upper layer of floor slab; after the columns, beams, walls of the layer where this layer of floor slab is located, the upper layer of floor slab of this layer of floor slab, and the decorative layer of the wall and the decorative layer of the ceiling inside the building corresponding to this layer of floor slab are all constructed, then remove the protective cushion layer A on the top surface of this layer of floor slab.

[0111] The proportion of the sound-insulating concrete adopts the proportion disclosed in the patent with the application number 202011348921.9.

[0112] By respectively arranging a sound-insulating concrete layer A and a sound-insulating concrete layer B at the bottom and top of the concrete base layer, effective sound insulation can be achieved. Moreover, the material of the sound-insulating concrete layer is sound-insulating concrete, which can ensure the connection strength with the concrete base layer, effectively avoid falling off or separation, and the strength of the sound-insulating concrete is also sufficient for the connection strength with other media during subsequent decoration construction.

[0113] Through the corrugated plate structure of the core plate, not only can the core plate have good compressive and tensile properties in the up and down directions and the waveform distribution direction of the corrugated plate with respect to the concrete base layer, but also the connecting rod A can form two upper and lower rows corresponding to the positions of the wave crests and wave troughs, thereby improving the connection strength between the two ends of the floor slab body and the beam.

[0114] The spiral part formed by the connecting rod A can not only effectively increase the contact range between the connecting rod and the concrete of the connecting layer, improve the strength of the concrete of the connecting layer, but also the spiral structure of the spiral part is convenient for axial tension and contraction, so that it can be adjusted according to the distance between the floor slab body and the beam during actual assembly.

[0115] Through the convex rods arranged at the top of the sound-insulating concrete layer B, not only can it be convenient for the floor slab to remove the corresponding convex rods at the corresponding positions according to the water and electricity pipe wiring diagram during construction to form a wiring groove, which is convenient for prefabricating water and electricity pipelines in the floor slab, but also it can further increase the height of the sound-insulating concrete layer and further improve the sound insulation effect of the floor slab.

[0116] Since the core plate is a mesh plate structure, it not only effectively reduces the weight of the core plate and the floor slab, but also is convenient for the pouring of the concrete base layer, thereby reducing the production cost; moreover, it can also make the connection effect between the core plate and the base concrete of the concrete base layer better, and then ensure the strength of the concrete base layer.

[0117] The core plate is fixedly connected to the reinforcement layer in the sound-insulating concrete layer through the connecting vertical rods, thereby further improving the connection strength between the concrete base layer and the sound-insulating concrete layer.

[0118] The wave crest position of the corrugated plate of the core plate is connected to the reinforcement layer of the sound-insulating concrete layer A through the connecting vertical rod, and the wave trough position of the corrugated plate of the core plate is connected to the reinforcement layer of the sound-insulating concrete layer B through the connecting vertical rod, so that internal stress can also be generated in the corrugated plate, and then the compressive, bending and flexural properties of the concrete base layer are greatly improved.

[0119] Pour the sound-insulating concrete layer A, the concrete base layer, and the sound-insulating concrete layer B successively from bottom to top. During the production and construction process of the sound-insulating floor slab body, no additional turnover is required. Just continuously add and heighten the side plates, side frames, and top plate molds above the pouring mold, which improves the production efficiency and also avoids losses during turnover.

[0120] The connecting vertical rods are bolts, which not only facilitate the connection and fixation between the corrugated board and the steel bar layer, but also can adjust the height between the steel bar layer and the corrugated board according to the sound-insulating floor slabs with different performance and size requirements, thus improving the production efficiency and applicability.

[0121] Through the action of the top plate mold, the sound-insulating concrete layer B can be quickly prepared, improving the production efficiency. Moreover, the top surface of the produced sound-insulating concrete layer B is horizontal, the convex rods on the top surface of the sound-insulating concrete layer B are evenly distributed, and the tops of the convex rods are also flush.

[0122] The floor slab structure from bottom to top is successively the sound-insulating concrete layer A of the precast floor slab body, the concrete base layer, the sound-insulating concrete layer B, the water and electricity wiring layer, the heat insulation layer, the floor heating laying layer, and the surface decoration layer. The formed two-layer sound-insulating layer can not only insulate the sound in the room below the floor slab, but also insulate the sound in the room above the floor slab. Moreover, during the floor slab construction, the construction party can directly embed the pipelines in the floor slab according to the unified pipeline, and directly uniformly lay the floor heating water pipes according to the construction requirements, ensuring the quality of the floor heating pipeline and the consistency of the heating efficiency of the floor heating pipeline.

[0123] After folding the connecting rod B, connect the adjacent precast floor slab bodies or beams through the fixing bolts. This is not only convenient for connection, but also can adjust the distance between adjacent precast floor slab bodies or the distance between the precast floor slab body and the beam by screwing the fixing bolts, thus ensuring the uniform distribution of the precast floor slab bodies on this floor, and further ensuring that the strength performance at each position of the floor slab of the floor meets the requirements and the strength performance is evenly distributed.

[0124] Through the structural setting of the heat insulation layer, it is ensured that the heat of the floor heating will not conduct heat downward to the floor slab, improving the heating effect of the floor heating.

[0125] The surface decoration layer is directly set above the floor heating laying layer, thus reducing the loss of the heat of the floor heating, and the heat generated by the floor heating can be quickly radiated from the surface.

[0126] It can be quickly assembled and constructed at the construction site, and the pipelines can be directly embedded in the floor slab according to the water and electricity pipelines, and the floor heating can be laid, thus improving the production efficiency and shortening the production cycle; moreover, the top surface of the floor slab is directly constructed to the surface decoration surface, so that during the subsequent decoration of the owner, there is no need to transform the ground, no need to damage the ground, and the decoration cycle is shortened.

[0127] When pouring the concrete on the layer for laying water and electricity pipelines, the top surface of the concrete is scraped by a squeegee to make the entire top surface of the floor slab lie in the same horizontal plane, thus facilitating the smooth laying of the subsequent cement fiber board.

[0128] Both between the cement fiber board and the layer for laying water and electricity pipelines and between adjacent cement fiber boards are fixedly connected by cement mortar, thus ensuring the connection strength between the cement fiber board and the layer for laying water and electricity pipelines.

[0129] After the laying of the cement fiber board is completed, the top surface of the cement fiber board is leveled by self-leveling of the horizontal mortar, thus ensuring that the laid floor heating reflective film is horizontal and the top surface of the cement fiber board on which the floor heating reflective film is laid is also absolutely flat, ensuring the heat reflection effect of the floor heating reflective film and further ensuring the heating effect of the floor heating.

[0130] Through the settings of the protective cushion layer A and the protective cushion layer B, the top surface and the bottom surface of the floor slab after the construction is completed are well protected, avoiding damage to the top surface or the bottom surface of the floor slab during the subsequent construction.
