Description

Technical Field

[0001] The present invention relates to the technical field of precast floor production and construction, and particularly to 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 constructing 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, different strength and thickness components 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 type, such as large panel buildings; box assembly type, such as reinforced concrete box buildings, wooden box buildings, etc.; frame assembly type, 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 great 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 sound insulation effects 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 sound insulation construction during decoration, when only individual owners carry out sound insulation construction 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 for people to keep warm in most parts of the country. The installation of floor heating is also carried out 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 floor heating effects and installation construction qualities of the installed construction are uneven, resulting in uneven heating effects achieved by central heating. Even if the installation construction quality is poor and the selected material quality is low, it 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 lower or adjacent neighbors. Moreover, the repair construction is complex, the construction period is long, and the construction cost is high.

[0005] Those skilled in the art all know that it is most convenient to lay the water and electricity pipelines in a house from the ground, and the amount of pipes used is the least. However, the pipelines in currently built residential buildings generally run through the walls. This is because the water connection interfaces in current houses basically only lead to the kitchen and bathroom, and the water pipelines in the rest of the house need to be modified by the owners during 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 rest of the 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 do not run through the floor slab but only through the wall.

[0006] Therefore, researching a precast floor slab that can facilitate the pre-laying of water and electricity pipes, effectively has a sound insulation effect, and is also convenient for the construction and heat conduction of 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 floor slab strength and reduce the decoration cost of the owners during later decoration, and for this purpose, a set of precast floor slab structures, corresponding production methods, and precast floor slab structures and corresponding construction methods are proposed. Summary of the Invention

[0007] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a sound-insulating floor slab that is convenient for water and electricity wiring and floor heating installation. The floor slab structure from bottom to top is successively a sound-insulating concrete layer A of the precast floor slab body, a concrete base layer, a sound-insulating concrete layer B, a water and electricity wiring layer, a heat-insulating layer, a floor heating laying layer, and a surface decoration layer. The formed two sound-insulating layers 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 construction of the floor slab, the construction party can directly embed the pipelines in the floor slab according to a unified pipeline, and directly lay the floor heating water pipes in accordance with the construction requirements, ensuring the quality of the floor heating pipeline and the consistency of the heating efficiency of the floor heating pipeline.

[0008] The technical solution adopted by the present invention is:

[0009] A sound-insulating floor slab facilitating the laying of water and electricity lines and the installation of underfloor heating, which sequentially includes a precast floor slab layer, a water and electricity line laying layer, a heat insulation layer, an underfloor heating laying layer, and a surface decoration layer from bottom to top. The precast floor slab layer includes a plurality of precast floor slab bodies fixedly connected to each other in sequence. Each precast floor slab body includes a concrete base layer. A sound-insulating concrete layer A is fixedly connected to the bottom of the concrete base layer. A sound-insulating concrete layer B is fixedly connected to the top of the concrete base layer. A core plate is fixedly connected to the middle part inside the concrete base layer. The part of the core plate corresponding to the concrete base layer is a corrugated plate and is uniformly arranged in sequence along the width direction of the concrete base layer. Connecting rods A are symmetrically and fixedly connected to the outer sides of the side walls of the core plate corresponding to the width direction of the concrete base layer respectively. Connecting rods B are symmetrically and fixedly connected to the outer sides of the side walls of the core plate corresponding to the length direction of the concrete base layer respectively.

[0010] A further improvement scheme of the present invention is that the connecting rods A are respectively arranged at the peak positions and trough positions of the corrugated plates.

[0011] A further improvement scheme of the present invention is that the part of the connecting rod A extending out of the concrete base layer is twisted into a spiral part, and one end of the connecting rod A far from the concrete base layer is twisted to be parallel to the plate surface of the precast floor slab body.

[0012] A further improvement scheme of the present invention is that a connecting plate parallel to the plate surface of the precast floor slab body is fixedly arranged at the edge of the side wall of the core plate corresponding to the length direction of the concrete base layer. The connecting plate extends out of the side wall of the concrete base layer in the length direction. The connecting rod B is fixedly connected to one side edge of the connecting plate far from the concrete base layer.

[0013] A further improvement scheme of the present invention is that a strip-shaped through hole is arranged along the length direction of the connecting rod B.

[0014] A further improvement scheme of the present invention is that a plurality of convex rods are uniformly arranged on the top surface of the sound-insulating concrete layer B.

[0015] A further improvement scheme of the present invention is that a water and electricity pipe is placed and fixed on the top surface of the sound-insulating concrete layer B. The convex rods at the positions corresponding to the water and electricity pipe on the top surface of the sound-insulating concrete layer B are removed to form a wiring groove. The water and electricity pipe is fixed in the wiring groove, and then medium sand concrete or coarse sand concrete is poured and filled to form a water and electricity line laying layer.

[0016] A further improvement scheme of the present invention is that the part of the core plate corresponding to the inside of the concrete base layer is a mesh plate uniformly distributed with a plurality of through holes.

[0017] A further improved solution of the present invention is that steel bar layers parallel to the plate surface of the precast floor slab body are respectively fixedly arranged in the sound insulation concrete layer A and the sound insulation concrete layer B. Each steel bar layer is fixedly connected to the core board through a plurality of connecting vertical rods respectively, and the connecting vertical rods are perpendicular to the plate surface of the precast floor slab body.

[0018] A further improved solution of the present invention is that the connecting vertical rods fixed to the sound insulation concrete layer A are fixed at the wave crest positions of the corrugated plates of the core board, and the connecting vertical rods fixed to the sound insulation concrete layer B are fixed at the wave trough positions of the corrugated plates of the core board.

[0019] A further improved solution of the present invention is that the connecting vertical rods are connecting bolts, and the connecting bolts respectively fix and connect the corresponding positions of the core board and the steel bar layer through nuts.

[0020] A further improved solution of the present invention is that both ends of the precast floor slab body are fixedly connected to the corresponding beams through connecting rod A, and both sides of the precast floor slab body are fixedly connected to the corresponding connecting rod B of the adjacent precast floor slab body on the corresponding side or to the corresponding beam on the corresponding side through connecting rod B.

[0021] A further improved solution of the present invention is that the connecting rod A of the precast floor slab body is fixed to the exposed steel bars of the beam at the corresponding end, and the connecting rod B of the outermost precast floor slab body facing the beam on the corresponding side is fixed to the exposed steel bars of the beam on the corresponding side.

[0022] A further improved solution of the present invention is that after the connecting rod B between two adjacent precast floor slab bodies is turned up or down simultaneously, they are fixedly connected through fixing bolts.

[0023] A further improved solution of the present invention is that a connection layer is formed by filling coarse sand concrete between both ends and both sides of the precast floor slab body and the corresponding beams at the corresponding ends, as well as between two adjacent precast floor slab bodies.

[0024] A further improved solution of the present invention is that the heat insulation layer sequentially includes a cement fiber board laid on the top surface of the water and electricity wiring layer from bottom to top and a floor heating reflective film fixed on the top surface of the cement fiber board.

[0025] A further improved solution of the present invention is that the length extension direction of the laid cement fiber board is perpendicular to the length direction of the precast floor slab body.

[0026] A further improved solution of the present invention is that the floor heating laying layer includes floor heating pipes fixed on the top surface of the heat insulation layer and is filled with coarse sand concrete.

[0027] A further improved solution of the present invention is that the surface decoration layer is a laid floor or floor tile.

[0028] The beneficial effects of the present invention are as follows:

[0029] First, for the sound-insulating floor slab facilitating the routing of water and electricity lines and the installation of underfloor heating, 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 line routing layer, the heat-insulating layer, the underfloor heating laying layer, and the surface decoration layer. The formed two sound-insulating layers 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 construction of the floor slab, the construction party can directly embed the unified pipeline in the floor slab according to the unified pipeline, and directly lay the underfloor heating water pipes uniformly according to the construction requirements, ensuring the quality of the underfloor heating pipeline and the consistency of the heating efficiency of the underfloor heating pipeline.

[0030] Second, for the sound-insulating floor slab facilitating the routing of water and electricity lines and the installation of underfloor heating, after folding the connecting rod B, it is connected to the adjacent precast floor slab body or beam through the fixing bolt. This not only facilitates the 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 bolt, thereby 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 distribution is uniform.

[0031] Third, for the sound-insulating floor slab facilitating the routing of water and electricity lines and the installation of underfloor heating, through the structural setting of the heat-insulating layer, it is ensured that the heat of the underfloor heating will not conduct heat downward to the floor slab, improving the heating effect of the underfloor heating.

[0032] Fourth, for the sound-insulating floor slab facilitating the routing of water and electricity lines and the installation of underfloor heating, the surface decoration layer is directly set above the underfloor heating laying layer, thereby reducing the loss of the heat of the underfloor heating, and the heat generated by the underfloor heating can be quickly radiated from the surface.

[0092] a) Fix the supports for the precast floor slab body 1 to be installed in advance below the position where the floor slab is to be installed, and then hoist the precast floor slab body 1 to the top of the floor successively through a lifting device, and fix them to the beams or the precast floor slab bodies 1 hoisted before respectively through the connecting rods A6 and the connecting rods B7;

[0093] A protective cushion layer B is provided on the bottom surface of the sound-insulating concrete layer A4 of the precast floor slab body 1 hoisted by the lifting device.

[0094] b) Then, according to the wiring drawings of the water and electricity pipelines on the floor where the precast floor slab body 1 is located, chisel off the convex rods 8 corresponding to the positions where the water and electricity pipes 14 pass through, so as to form a wiring groove 12, and then carry out the wiring of the water and electricity pipelines;

[0095] c) Pouring templates are respectively fixed at the bottom of the connection between adjacent precast floor slab bodies 1, the bottom of the connection between the precast floor slab body 1 and the beam, and the beam corresponding to the edge of the floor range formed by the hoisted precast floor slab bodies 1, and medium sand concrete or coarse sand concrete is poured successively or simultaneously for the connection layer 16 and the water and electricity wiring layer 15;

[0096] 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, first pour the connection layer 16, and then pour the water and electricity wiring layer 15 after the concrete of the connection layer 16 has solidified;

[0097] When pouring the water and electricity wiring layer 15, the top surface of the concrete is scraped by a scraper to make the entire floor top surface lie in the same horizontal plane;

[0098] The top surface of the water and electricity wiring layer 15 is higher than the top surface of the convex rod 8 and higher than the top of the floor heating pipeline 18;

[0099] d) After the connection layer 16 has solidified, immediately remove the pouring template corresponding to the connection layer 16 and remove the support members under the construction floor slab;

[0100] After removing the pouring template corresponding to the connection layer 16 and the support members under 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 under the construction floor slab;

[0101] After the concrete of the water and electricity wiring layer 15 has solidified, remove each pouring template in step c), and then lay and fix the cement fiber board 17 on the top of the water and electricity wiring layer 15 in sequence;

[0102] 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;

[0103] After the cement fiber board 17 is laid, the top surface of the cement fiber board 17 is leveled by horizontal mortar self-leveling;

[0104] 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;

[0105] f) Lay the connected floor heating pipes 18 on the top surface of the floor heating reflective film 19 in sequence, and pour coarse sand concrete to form the floor heating laying layer 20;

[0106] When pouring the floor heating laying layer 20, use a scraper to scrape the top surface of the entire floor slab to be in the same horizontal plane at the top surface of the concrete;

[0107] g) After the concrete of the floor heating laying layer 20 solidifies, then carry out the construction of 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;

[0108] The surface decoration layer 21 is any one or more of the laid floor tiles, floors or stone slabs, or the surface decoration layer 21 is a terrazzo layer or a floor cushion layer;

[0109] 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 construction of the columns, beams, walls of the floor slab where this layer is located, the upper layer of floor slab of this layer, and the decorative layers of the walls and the decorative layer of the ceiling in the building corresponding to this layer of floor slab are all completed, then remove the protective cushion layer A on the top surface of this layer of floor slab.

[0110] The mixing ratio of the sound insulation concrete adopts the mixing ratio disclosed in the patent with the application number 202011348921.9.

[0111] By respectively arranging the sound insulation concrete layer A and the sound insulation concrete layer B at the bottom and top of the concrete base layer, effective sound insulation can be achieved, and the material of the sound insulation concrete layer is sound insulation concrete, so as to ensure the connection strength with the concrete base layer, effectively avoid falling off or separation, and the strength of the sound insulation concrete is also sufficient for the connection strength with other media during subsequent decoration construction.

[0112] Through the corrugated plate structure of the core plate, not only can the core plate have good compressive and tensile properties for the concrete base layer in the up and down directions and the waveform distribution direction of the corrugated plate, 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.

[0113] 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 stretching and contraction, so that it can be adjusted according to the distance between the floor slab body and the beam during actual assembly.

[0114] Through the convex rods provided at the top of the sound-insulating concrete layer B, it is not only convenient to remove the corresponding convex rods according to the water and electricity pipe wiring diagram during the construction of the floor slab to form a wiring groove and facilitate the prefabrication of water and electricity pipelines in the floor slab, but also can further increase the height of the sound-insulating concrete layer, further improving the sound insulation effect of the floor slab.

[0115] Since the core board is a mesh board structure, it not only effectively reduces the weight of the core board and the floor slab, but also facilitates the pouring of the concrete base layer, thus reducing the production cost; moreover, it can also make the connection effect between the core board and the base concrete of the concrete base layer better, thereby ensuring the strength of the concrete base layer.

[0116] The core board is connected and fixed to the steel bar layer in the sound-insulating concrete layer through connecting vertical rods, thereby further improving the connection strength between the concrete base layer and the sound-insulating concrete layer.

[0117] The wave crest position of the corrugated board of the core board is connected to the steel bar layer of the sound-insulating concrete layer A through a connecting vertical rod, and the wave trough position of the corrugated board of the core board is connected to the steel bar layer of the sound-insulating concrete layer B through a connecting vertical rod, so that internal stress can also be generated in the corrugated board, and further greatly improve the compressive, flexural and flexural properties of the concrete base layer.

[0118] The sound-insulating concrete layer A, the concrete base layer and the sound-insulating concrete layer B are poured successively from bottom to top. During the production and construction of the sound-insulating floor slab body, no additional turnover is required. It is only necessary to 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.

[0119] The connecting vertical rod is a bolt, which is not only convenient for connecting and fixing the corrugated board to 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.

[0120] Through the function 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.

[0121] The floor slab structure from bottom to top is successively the sound-insulating concrete layer A, 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 of the precast floor slab body. The formed two-layer sound insulation 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 construction of the floor slab, the construction party can directly embed the unified pipeline in the floor slab according to the unified requirements, 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.

[0122] After folding the connecting rod B and connecting it to the adjacent precast floor slab body or beam through the fixing bolts, it is not only convenient to connect, but also the distance between adjacent precast floor slab bodies or the distance between the precast floor slab body and the beam can be adjusted by screwing the fixing bolts, so as to ensure the uniform distribution of the precast floor slab bodies on this floor, and further ensure that the strength performance at each position of the floor slab of the floor meets the requirements and the strength performance is evenly distributed.

[0123] Through the structural setting of the heat insulation layer, it is ensured that the heat of the floor heating will not conduct downward to the floor slab, improving the heating effect of the floor heating.

[0124] 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.

[0125] The construction can be quickly assembled and completed 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 there is no need to transform the ground during the subsequent decoration of the owner, and there is no need to damage the ground, shortening the decoration cycle.

[0126] When the concrete top surface of the water and electricity wiring layer is poured, the entire top surface of the floor slab is scraped to be in the same horizontal plane by a scraper, which is convenient for the subsequent smooth laying of the cement fiber board.

[0127] Both between the cement fiber board and the water and electricity wiring layer and between adjacent cement fiber boards are fixedly connected through cement mortar, thus ensuring the connection strength between the cement fiber board and the water and electricity wiring layer.

[0128] After the cement fiber board is laid, the top surface of the cement fiber board is leveled by horizontal mortar self-leveling, so as to ensure 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.

[0129] Through the setting of the protection cushion A and the protection cushion 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.
