Abstract
Description
Technical Field
[0001] This invention relates to the field of building wall panel design technology, specifically to a production method for an integrated thermal insulation and soundproof composite panel. Background Technology
[0002] In Sichuan, prefabricated composite floor slabs extensively utilize truss-reinforced concrete composite base slabs. Their thermal and sound insulation employs the traditional floating insulation method, which involves placing a fine aggregate concrete protective layer on top of the insulation board. However, this method reduces the net height of living spaces and increases the floor slab's weight, contradicting the goals outlined in the "Implementation Plan." Furthermore, the wet work involved in on-site cutting, splicing, and installation of the insulation board with water violates the industrialized and green construction methods of prefabricated buildings and makes it difficult to control the floor slab construction quality. Therefore, current prefabricated floor slabs fail to integrate thermal and sound insulation with the structure in both design and construction, impacting the livability of residences and hindering the development of prefabricated green buildings.
[0003] To address the aforementioned issues, Chinese patent CN114922330A discloses an integrated prefabricated composite floor slab with thermal insulation and sound insulation structure. This slab includes upper and lower polymer mortar surface layers for thermal insulation and sound insulation, with a reinforcing mesh on the polymer mortar surface layers. The steel truss of the composite slab is flexibly connected to the mesh via connectors on the thermal insulation and sound insulation template. Finally, concrete is poured to form an integrated prefabricated floor slab with the steel truss and insulation board. The thermal insulation and sound insulation system in this patent requires the insulation board to be laid under the existing composite slab using connectors to meet the thermal insulation and sound insulation requirements, increasing the thickness of the entire composite floor slab and thus reducing the usable floor height. Furthermore, due to the addition of connectors, additional fixing plates and anchor bolts need to be installed on the insulation board, making the manufacturing process complex and failing to effectively utilize the advantages of industrialized prefabricated building production.
[0004] In addition, in the existing integrated thermal insulation and sound insulation panel structure, the thermal insulation and sound insulation layers are all made of porous materials. Although they have good thermal insulation and sound insulation properties, their material strength is low. During the transportation and installation of the product, pads and supports need to be set at the bottom of the product as stress points. Therefore, the existing thermal insulation and sound insulation products cannot be transported and installed after molding. Furthermore, the existing products do not consider the issue of pre-reserved junction boxes in the composite panels. However, in actual projects, junction boxes are often pre-reserved on the surface of the composite panels. Therefore, the existing thermal insulation and sound insulation composite panel products still require drilling operations after installation to allow pipes to pass through.
[0005] This invention, while ensuring the product's thermal insulation and soundproofing performance, fully solves the problems of existing products being unable to be transported and installed, and the need for pre-installed junction boxes. Summary of the Invention
[0006] To address the shortcomings of existing technologies, this invention aims to provide a production method for an integrated thermal insulation and soundproof composite slab. This method involves embedding the thermal insulation and soundproof layer within a groove, inserting reinforcing bars into the connecting groove, and then pouring concrete to connect the composite slab layer and the thermal insulation and soundproof layer as a single unit. This avoids the impact on thermal insulation performance caused by tie rods and ensures the usable floor height, aligning with the current trend of green and energy-saving prefabricated building development.
[0007] This invention is achieved through the following technical solution:
[0008] A method for producing an integrated thermal insulation and soundproof composite panel includes the following steps:
[0009] S1: Install the thermal insulation and sound insulation layer mold, and install several groove-shaped tooling on the mold;
[0010] S2: Pour thermal insulation and sound insulation lightweight concrete into a mold to form a thermal insulation and sound insulation layer with several connecting grooves. The connecting grooves are located on the upper side of the thermal insulation and sound insulation layer and are set along the width direction of the thermal insulation and sound insulation layer.
[0011] S3: Maintain and remove the trough-shaped tooling;
[0012] S4: A steel mesh and truss reinforcement are laid on the side of the thermal insulation and sound insulation layer, and the bottom reinforcement of the steel mesh extends into several of the connecting grooves.
[0013] S5: Embed a junction box on the side of the thermal insulation and soundproofing layer;
[0014] S6: Subsequently, a composite board layer mold is installed on the upper side of the thermal insulation and sound insulation layer, and concrete is poured to form a composite board layer. The lower side of the composite board layer has a groove, and the groove embeds the thermal insulation and sound insulation layer inside. The lower side of the composite board layer is flush with the lower side of the thermal insulation and sound insulation layer.
[0015] S7: Finally, cure and demold, and the composite floor slab is completed.
[0016] Compared to existing technologies, where thermal insulation and sound insulation systems require the installation of insulation boards under the existing composite slab using connectors to meet insulation and sound insulation requirements, increasing the thickness of the entire composite floor slab and thus reducing the usable floor height; furthermore, the addition of connectors necessitates the installation of fixing plates and anchor bolts on the insulation board, complicating the manufacturing process and failing to effectively utilize the advantages of industrialized production in prefabricated buildings, this invention provides a method for producing an integrated thermal insulation and sound insulation composite slab. Specifically, the method involves first pouring lightweight thermal insulation and sound insulation concrete to form a thermal insulation and sound insulation layer, and then... The surface has several connecting grooves formed by groove-shaped tooling, and the connecting grooves can be concave, dovetail, arch, or other structural forms. Then, steel mesh and truss steel bars are laid, and the bottom steel bars of the steel mesh are extended into the connecting grooves. At this time, when the composite slab layer is poured, the poured concrete can enter the connecting grooves, so that after the composite slab layer is formed, the composite slab layer and the thermal insulation and sound insulation layer are connected as one. Secondly, when pouring the composite slab layer, it is necessary to ensure that the thermal insulation and sound insulation layer is embedded in the lower side of the composite slab layer, so that the lower side of the composite slab layer and the thermal insulation and sound insulation layer are flush, thereby ensuring the floor height and usable space.
[0017] Further optimization includes the following sub-steps in step S1:
[0018] Before installing the thermal insulation and sound insulation layer mold, several pads need to be pre-embedded on the mold platform. The pads are located inside the thermal insulation and sound insulation layer, and the bottom of the pads is flush with the lower side of the thermal insulation and sound insulation layer.
[0019] Further optimization includes the following sub-steps in step S1:
[0020] Before installing the thermal insulation and sound insulation layer mold, several positioning blocks need to be fixed on the mold table according to the location and quantity of the pre-embedded junction boxes. The positioning blocks are located inside the thermal insulation and sound insulation layer. The bottom of the positioning block is flush with the lower side of the thermal insulation and sound insulation layer, and the top of the positioning block is flush with or extends beyond the upper side of the thermal insulation and sound insulation layer.
[0021] Further optimization involves increasing the cross-sectional size of the positioning block from top to bottom.
[0022] Further optimization involves connecting the positioning block to the junction box via bolts.
[0023] To further optimize this process, step S4 also includes the following sub-steps:
[0024] After the bottom reinforcing bars are inserted into several of the connecting grooves, the upper reinforcing bars in the bottom reinforcing bars extend out of both ends of the connecting grooves, and the connecting grooves are continuous along the width direction of the thermal insulation and sound insulation layer.
[0025] Further optimization involves chamfering at both the top and bottom corners of the cross-section of the composite plate layer.
[0026] To further optimize this process, step S7 also includes the following sub-steps:
[0027] After the composite floor slabs are manufactured, several of the composite floor slabs are transported to the site. When two composite floor slabs are connected, the ends of the two composite floor slabs are joined together, and concrete is poured at the chamfered corner of the upper joint, while crack-resistant mortar is filled at the chamfered joint of the lower joint.
[0028] To further optimize the process, when splicing the ends of two composite floor slabs, lapped reinforcing bars need to be installed between the two composite floor slabs, with both ends of the lapped reinforcing bars lapped onto the upper sides of the two composite floor slabs respectively.
[0029] Further optimization involves pulling out several positioning blocks after the composite floor slab is installed using a screw-out tool. Each positioning block has a through threaded hole from top to bottom. The screw-out tool is T-shaped, and its long rod portion has an external thread that matches the threaded hole.
[0030] Compared with the prior art, the present invention has the following advantages and beneficial effects:
[0031] 1. This invention provides a method for producing integrated thermal insulation and soundproof composite slabs. The precast floor slabs produced using this method are lighter, reducing the self-weight of precast components by more than 50%. Compared with existing thermal insulation and soundproofing layer methods, the usable floor space is increased by 3-5 cm because the thermal insulation and soundproofing panels are embedded in the composite slab. The absence of tie rods and other auxiliary tools reduces structural costs. The floor slab steel mesh and truss steel bars can be hoisted and installed as a whole after binding, eliminating the need for reconnection processes. The floor slab splicing adopts a close-fitting structure, effectively improving the efficiency of component installation.
[0032] 2. This invention provides a method for producing an integrated thermal insulation and soundproof composite panel. A positioning block of a suitable size is set in the wiring hole to avoid the problem that the composite floor panel cannot be transported and installed due to insufficient material strength of the thermal insulation and soundproof layer as the bottom layer. In addition, the positioning block can also serve as a positioning block for the junction box, thereby ensuring the rapid installation of the junction box.
[0033] 3. This invention provides a method for producing an integrated thermal insulation and sound insulation composite panel. By prefabricating pads inside the thermal insulation and sound insulation layer, the thermal insulation and sound insulation products can be transported and installed after forming.
[0034] 4. This invention provides a production method for an integrated thermal insulation and sound insulation composite board, which solves the problem of the existing thermal insulation and sound insulation composite board products requiring on-site drilling and excavation based on the location of the pre-embedded junction box after installation.

[0045] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.
[0046] Example 1
[0047] This embodiment 1 provides a prefabricated thermal insulation and soundproof composite floor slab, such as Figures 1 to 3 As shown, it includes a composite slab layer 1 and a thermal insulation and soundproofing layer 2;
[0048] The side of the composite slab layer 1 is provided with a groove, and the thermal insulation and sound insulation layer 2 is embedded in the groove. The outer side of the thermal insulation and sound insulation layer 2 is flush with the side of the composite slab layer 1.
[0049] The inner side of the thermal insulation and sound insulation layer 2 has several connecting grooves; the bottom side of the groove has several protrusions embedded in the connecting grooves, and the bottom steel bar 3 of the composite slab layer 1 extends into the connecting grooves.
[0050] Compared to existing technologies, where insulation and soundproofing systems require the installation of insulation boards under the existing composite slab using connectors to meet insulation and soundproofing requirements, increasing the thickness of the entire composite floor slab and thus reducing the usable floor height, this solution addresses the problem of complex manufacturing processes due to the added connectors necessitating the installation of fixing plates and anchor bolts on the insulation board. This prevents the effective utilization of the advantages of prefabricated building industrial production. This solution provides a prefabricated insulation and soundproofing composite floor slab, specifically comprising a composite slab layer 1 and an insulation and soundproofing layer 2 made of lightweight aggregate concrete. The composite slab layer 1 has a groove on its side, into which the insulation and soundproofing layer 2 is embedded, ensuring a flush fit. This achieves insulation and soundproofing while avoiding increasing the overall thickness of the composite floor slab, thus preserving the usable floor height. Furthermore, the inner surface of the insulation and soundproofing layer 2 has a connecting groove for connecting with a protrusion on the inner side of the groove, thereby integrating the composite slab layer 1 and the insulation and soundproofing layer 2 into a single unit, thus avoiding… The existing technology suffers from the impact of tie-in components on thermal insulation performance; the connecting groove can be concave, dovetail, arch, or other structural forms, thus stably embedding the thermal insulation and sound insulation board into the composite slab, reducing the overall thickness of the composite floor slab and increasing the usable clear height; the protrusion is concrete poured simultaneously with the composite slab layer 1 using the same material, and is reinforced with steel bars; to ensure a stable bond between the thermal insulation and sound insulation board and the post-poured concrete surface, the upper surface of the thermal insulation and sound insulation board can be made into a roughened surface; in specific operation, firstly, a lightweight aggregate concrete thermal insulation and sound insulation board made of silicate cement, shale ceramsite, polypropylene fiber, foaming agent, and other additives is prefabricated, and the pre-reserved connecting groove in the board is a through groove structure, the spacing and number of which are determined according to the spacing and number of bottom steel bars 3 in the design drawings; after the steel mesh and truss steel bars 4 are tied together, the whole assembly is hoisted and placed on the thermal insulation and sound insulation board, wherein the bottom steel bars 3 are placed in the pre-reserved groove, and the upper steel bars and truss steel bars 4 are placed on the upper surface of the thermal insulation and sound insulation board. After installation, pour concrete for the composite slab layer 1.
[0051] Please see Figure 1 and Figure 2 As a specific implementation method to facilitate the connection of composite floor slabs to beams, the method is configured as follows: the connecting groove runs through the width of the thermal insulation and sound insulation layer 2, and several connecting grooves are evenly distributed along the length of the thermal insulation and sound insulation layer 2; the upper layer steel bar 5 in the bottom steel bar 3 extends out of both ends of the connecting groove.
[0052] It is understood that in this embodiment, there are multiple connecting slots, all of which are through slots, thus facilitating the upper reinforcing bars 5 in the bottom reinforcing bars 3 to pass through two connecting slots and be stably connected to the beam; the upper opening size of the connecting slot is 2.5 times the diameter of the bottom reinforcing bar 3, the overall depth is 1.5 times the diameter of the bottom reinforcing bar 3, and the width of the lower connecting slot is 3 times the diameter of the bottom reinforcing bar 3. The cavity of the connecting slot is filled and compacted with post-cast concrete.
[0053] Please see Figure 3 As a specific implementation method to facilitate later installation, the method is configured such that: the ends of the composite slab layer 1 are chamfered, the ends of adjacent composite slab layers 1 are spliced together and connected by lapped steel bars 6, and the two ends of the lapped steel bars 6 are respectively lapped on the upper side of the two composite slab layers 1; in this embodiment, the chamfered ends are used to facilitate later installation, and both the upper and lower ends of the chamfered ends are chamfered, and then the two are fixedly connected by lapped steel bars 6.
[0054] Please continue reading. Figure 3 As a specific implementation method for filling and sealing the joints, the joints of adjacent composite slab layers 1 are filled with crack-resistant mortar 7; in this embodiment, an additional 50cm thick concrete is poured at the upper chamfered joint between composite slab layers 1 to wrap the thermal insulation and sound insulation board, and the lower chamfered joint is filled and sealed with polymer-modified crack-resistant mortar 7.
[0055] Example 2
[0056] This embodiment 2 is a further optimization based on embodiment 1, such as... Figures 4-7 As shown.
[0057] Compared to existing technologies, which do not consider the issue of pre-installed junction boxes 9 in composite panels, while in actual engineering projects, composite panels often have pre-installed junction boxes 9 on their surface, existing thermal insulation and soundproof composite panel products still require drilling operations after installation to allow pipes to be installed. This is time-consuming, labor-intensive, and easily damages the thermal insulation and soundproof layer 2. This embodiment provides a specific implementation method to avoid damage to the thermal insulation and soundproof layer 2 during transportation. Please refer to [link / reference]. Figure 4 The configuration is as follows: several wire holes are reserved on the inner side of the thermal insulation and sound insulation layer 2, and a positioning block 10 is provided in the wire holes. The positioning block 10 has a through threaded hole in the middle, and the top of the positioning block 10 is used to position the wire box 9.
[0058] It is understandable that in this embodiment, during the casting and molding stage of the thermal insulation and sound insulation layer 2, a wire hole is pre-reserved. Since the material of the thermal insulation and sound insulation layer 2 is easily damaged during transportation, after the thermal insulation and sound insulation layer 2 is integrally formed, a positioning block 10 of appropriate size is set in the wire hole. This avoids the problem that the thermal insulation and sound insulation layer 2, as the bottom layer, cannot be transported and installed due to insufficient material strength during the transportation of the composite floor slab. In addition, since the installation position of the junction box 9 in the composite floor slab must be precisely positioned in the prior art, the positioning block 10 can also serve to position the junction box 9, thereby ensuring the rapid installation of the junction box 9. The connecting block is preferably a wooden block, which is used to avoid hard contact with the thermal insulation and sound insulation layer 2 through the wooden positioning block 10. The junction box 9 can be directly fixed and installed using the upper surface of the wooden block as a positioning buckle or bolt.
[0059] Please see Figure 7 As a specific embodiment for quickly removing the positioning block 10, it is configured as follows: it also includes a screwing tool 11. The top of the positioning block 10 is connected to the junction box 9 by bolts and threads. The screwing tool 11 is T-shaped, and the long rod of the screwing tool 11 has external threads that are compatible with the threaded hole. In this embodiment, the positioning block 10 has a through threaded hole from the ground to the middle of the top surface, and is connected to the junction box 9 by bolts. When it is necessary to remove the positioning block 10, the bolts are unscrewed, and the long rod of the screwing tool 11 is screwed into the threaded hole, and then pulled out with force. The screwing tool 11 is not shown in the attached drawings and is similar to a wine opener.
[0060] Please see Figure 5 As a specific implementation method to facilitate the pulling out of the positioning block 10, the positioning block 10 is configured such that the cross-sectional size gradually increases from the top to the bottom. In this embodiment, the positioning block 10 can preferably be in the shape of a T-shaped column, a frustum, or a polygonal column, or other shapes.
[0061] As a redundancy scheme, the draft angle of the positioning block 10 is set to 2-3°.
[0062] Please see Figure 6 In this embodiment, the top of the positioning block 10 has a protruding rectangular platform, the top size of which is adapted to the bottom size of the wire box 9.
[0063] Please see Figure 4Because the existing integrated thermal insulation and sound insulation panel structure uses porous materials for the thermal insulation and sound insulation layer 2, although it has good thermal insulation and sound insulation properties, its material strength is low. During product transportation and installation, pads and supports need to be set at the bottom of the product as stress points. Therefore, existing thermal insulation and sound insulation products cannot be transported and installed after molding. This embodiment facilitates the transportation of composite floor slabs by pre-embedding a pad 8 inside the thermal insulation and sound insulation layer 2. The bottom of the pad 8 is flush with the outer surface of the thermal insulation and sound insulation layer 2. The pad 8 is prefabricated inside the thermal insulation and sound insulation layer 2. The pad 8 is made of sound-absorbing and vibration-damping bricks supported by cork, thus connecting with the thermal insulation and sound insulation layer 2 as a whole and having the same function. Its overall shape is an inverted T-shaped column with a larger top and smaller bottom. The bottom is flush with the outer surface of the thermal insulation and sound insulation layer 2, which facilitates the support.
[0064] Example 3
[0065] This embodiment 3 further optimizes the embodiment 2 and provides a specific construction process, including the following specific steps:
[0066] Step 1: Clean the mold table.
[0067] Step 2: According to the dimensions of the composite slab, fix the pre-embedded component transportation and installation pad 8 on the mold table; the pad 8 is a sound insulation and vibration damping brick made of cork, with a size of 100mm×100mm (length×width) and a height of 30-40mm, which is the thickness of the thermal insulation and sound insulation layer 2. The pad 8 is set with a draft angle of 2-3 degrees and its shape is approximately an inverted trapezoid, forming a shape that is larger at the top and smaller at the bottom; the pad 8 is placed at the corresponding point specified in the design drawings.
[0068] Step 3: According to the location and quantity of the pre-embedded junction boxes 9 in the drawings, fix the positioning blocks 10 for positioning the pre-embedded junction boxes 9 on the mold table; the positioning blocks 10 are made of wood and are 100mm×100mm (length×width). The top of the positioning blocks 10 has a rectangular platform that is 210mm higher than the thermal insulation and sound insulation layer. The size is the opening size of the junction box 9. The junction box 9 can be directly fastened to the rectangular platform for positioning or positioned by threaded connection; the positioning blocks 10 are set with a draft angle of 2 to 3 degrees and are approximately trapezoidal in shape, that is, the shape is smaller at the top and larger at the bottom. There is a through threaded hole inside.
[0069] Step 4: Apply a release agent to the mold of the thermal insulation and soundproof layer 2. The release agent is a water-based release agent.
[0070] Step 5: Install the second mold for the thermal insulation and soundproofing layer;
[0071] Step 6: Install several trough-shaped fixtures. The trough-shaped fixtures should be set according to the spacing and quantity of the bottom steel bar mesh. The trough-shaped fixtures are through-slot structures. The upper opening size is 2.5 times the diameter of the bottom steel bar, the overall depth is 1.5 times the diameter of the bottom steel bar, and the lower through-slot width is 3 times the diameter of the bottom steel bar.
[0072] Step 7: Pour thermal insulation and sound insulation lightweight concrete to form thermal insulation and sound insulation layer 2; the lightweight concrete to be poured is made of silicate cement, shale ceramsite, polypropylene fiber, foaming agent and other additives.
[0073] Step 8: Then maintain and remove the channel-shaped tooling; when dismantling the mold, the channel-shaped tooling and the side molds for splicing the plates need to be removed, but the side molds for the product and the beam do not need to be removed.
[0074] Step 9: Lay the steel mesh and truss reinforcement 4; the bottom steel mesh 3 and the upper steel mesh are tied together with wire in a quincunx pattern. During laying, the whole structure can be hoisted into the mold. The bottom steel mesh 3 is placed in the pre-formed connecting groove, and the upper steel mesh is laid directly on the surface of the pre-formed thermal insulation and sound insulation layer 2. Since the thickness of the thermal insulation and sound insulation layer 2 is the same as the design requirement of the steel reinforcement protective layer, there is no need to place additional mortar spacers to meet the thickness requirements of the steel reinforcement protective layer.
[0075] Step 10: Embed the junction box 9 on the upper surface of the thermal insulation and sound insulation layer 2; The junction box 9 is installed by directly upside down on the positioning block 10 embedded in step 3, and it is fixed by being connected to the rectangular platform of the positioning block 10 by a snap or thread.
[0076] Step 11: Installation of the composite slab bottom structural layer mold; The composite slab bottom structural layer mold is placed directly on the mold in step 5, and the two sets of molds are connected and fixed by T-bolts.
[0077] Step 12: Concrete pouring for the composite floor slab structural layer; the composite slab has a 50mm wide concrete frame on the splicing side between the slabs, with a 15mm chamfer at the top and a 10mm chamfer at the bottom.
[0078] Step 13: Final curing and demolding; the composite floor slab is now complete.
[0079] Step 14: Transport the completed composite floor slabs to the site for installation and pour the post-cast strip at the slab joints; the products are transported by stacking them in an overlapping manner, with the pre-embedded pad 8 in step 2 serving as the support point between each layer. The support point can avoid the problem that the thermal insulation and sound insulation layer 2 cannot be transported due to its porous material and insufficient strength.
[0080] Step 15: After the pouring is completed, the grooves of the joints between the slabs are treated; the upper joints of the slabs are filled with post-poured concrete, and the lower joints are filled and sealed with polymer-modified mortar.
[0081] Step 16: Use the screw-out tool 11 to remove the positioning block 10 from the thermal insulation and sound insulation layer 2; when removing the junction box 9, a threaded tool rod is required. The rod is 100mm long and the thread length is 30mm. When using it, the rod thread should be fully screwed into the positioning block 10. After screwing it in, pull the rod outward and remove the positioning block 10 through the interaction force between the threads, leaving an opening for the junction box 9 to be threaded later.
