Description
Technical Field
[0001] The present invention relates to the technical field of thermal insulation boards, and in particular to a construction method for a novel internal pouring and external splicing combined system of a disassembly-free thermal insulation integrated board. Background Art
[0002] With increasing demands for energy efficiency in buildings, adding insulation panels to exterior wall construction is a mainstream solution. Insulation panels are applied to the building envelope to reduce heat loss from indoor spaces, thereby maintaining indoor temperatures. Initially, insulation panels were installed separately after the concrete walls were cast. Later, to extend the service life of insulation panels, a cast-in-place concrete composite insulation construction technique was developed, in which insulation panels are bonded to the wall using steel mesh. The concrete walls on either side of the insulation panels are connected using insulation connectors and steel mesh.
[0003] During actual construction, it was found that the above construction method had the following technical problems: the above insulation board was connected to the cast-in-place shear wall through insulation connectors and wire mesh, and was not directly cast integrally with the cast-in-place shear wall, resulting in poor fixing effect of the insulation board. Summary of the Invention
[0004] In response to the deficiencies in the above-mentioned background technology, the present invention proposes a new construction method for an internally cast and externally assembled combined system of disassembly-free thermal insulation integrated panels, which solves the technical problem that in the existing construction method, the thermal insulation panels are connected to the cast-in-place shear walls through thermal insulation connectors and steel wire mesh frames, but are not directly cast integrally with the cast-in-place shear walls, resulting in poor fixing effect of the thermal insulation panels.
[0005] The technical solution of the present invention is achieved as follows: a new type of construction method for an internal pouring and external splicing combination system of a non-disassembly-required thermal insulation integrated panel, comprising the following steps: Step 1: Layout the thermal insulation panels, make steel formwork, and cut and assemble the thermal insulation panels in sequence; simultaneously produce and transport prefabricated components to the construction site; Step 2: Mark the prefabricated component lines, cast-in-situ shear wall column lines and wall column control lines on the floor; Step 3: Hoist and fix the prefabricated components to the corresponding laying-out positions; Step 4: Tie up the steel bars at the cast-in-situ shear wall and install the water and electricity pipelines; after tying up the steel bars at the cast-in-situ shear wall and the embedded water and electricity pipelines, install the wall column aluminum formwork; Step 5: Hoist the thermal insulation panels and the steel formwork to the preset position. After the thermal insulation panels are in place, The aluminum formwork and the insulation board on the outside are reinforced and connected by bolts; the integrated steel-plastic anchor bolts of the insulation structure are driven into the insulation board through the anchor holes reserved on the insulation board; Step 6: Install the beam and slab formwork and independent support; Step 7: Tie the steel bars and install the water and electricity pipelines at the beam and slab; Hoist the composite slab and connect the composite slab with the steel bars at the beam and slab; Step 8: Pour concrete into the space between the aluminum formwork of the cast-in-place shear wall columns, the space between the aluminum formwork at the connection between the prefabricated components and the cast-in-place shear wall, and the space between the inner aluminum formwork and the insulation board on the outside; Step 9: Treat the joints between the insulation board on the exterior wall and the prefabricated components of the exterior wall; Step 10: Protect the insulation board after construction is completed. In the construction method of the present application, the insulation board is used as the exterior wall formwork that does not need to be dismantled, and the steel-plastic anchor bolts and bolts of the integrated insulation structure connected to the insulation board are directly cast into the cast-in-place shear wall, forming an integrated connection between the insulation board and the cast-in-place shear wall, which greatly improves the fixing effect of the insulation board and solves the technical problem that the insulation board is connected to the cast-in-place shear wall through insulation connectors and steel wire mesh in the existing construction method, but is not directly connected to the cast-in-place shear wall as an integral whole, resulting in poor fixing effect of the insulation board.
[0006] The outer side of the insulation board is installed with a steel formwork, and the loose insulation boards are assembled into the outer formwork of the overall exterior wall according to the size determined in the design drawing through the steel formwork. They are hoisted to the corresponding position of the floor and combined with the aluminum formwork on the inner side of the exterior wall to form the casting formwork of the exterior wall. This design effectively improves the molding quality of the exterior wall insulation board.
[0007] The exterior walls of the cast-in-place part adopt the non-removal insulation board construction technology. The non-removal insulation board is applied to the outside of the exterior wall, and the aluminum formwork is used on the inside. The insulation board does not need to be removed after being cast together with the main body. The non-removal insulation board is used instead of the external formwork, which does not need to be removed later, thus solving the problem of difficult control of the exterior wall quality and saving the cost of external formwork rental, support and removal.
[0008] During construction, except for the outer side of the wall, insulation boards that do not need to be removed are used, and the rest of the cast-in-place parts are all made of aluminum alloy formwork. The use of aluminum alloy formwork has fast construction speed and good molding quality.
[0009] Preferably, the prefabricated components in step 3 are coded and hoisted in sequence according to the component codes. After the prefabricated components are coded, it is convenient to quickly hoist the prefabricated components to the corresponding positions according to the component codes, which is conducive to improving the installation efficiency of the prefabricated components.
[0010] Preferably, when tying the steel bars in step 4, the interior wall steel bars are tied after the exterior wall steel bars. That is, when tying the wall column steel bars, the exterior wall steel bars are tied first, and the plumbing and electrical installation are synchronized with the steel bar tying. After the exterior wall steel bars and the water and electricity pipelines are installed, the insulation workers begin to install the outer insulation board, and the reinforcement workers simultaneously tie the interior wall steel bars. The plumbing and electrical installation are carried out simultaneously with the steel bar tying without affecting the overall progress.
[0011] Preferably, concrete support bars and I-shaped steel bars are provided between the insulation board and the aluminum formwork in step five, and the concrete support bars and I-shaped steel bars are arranged perpendicularly to the steel bars at the cast-in-place shear wall. The provision of the concrete support bars and I-shaped steel bars is to ensure the thickness of the cast-in-place shear wall, and to avoid the situation where the cast-in-place shear wall thickness is insufficient due to excessive tightening between the insulation board and the aluminum formwork. The concrete support bars and I-shaped steel bars are arranged perpendicularly to the steel bars at the cast-in-place shear wall to ensure that the size of the concrete support bars and I-shaped steel bars is the same as the thickness of the cast-in-place shear wall, so as to ensure the thickness of the cast-in-place shear wall.
[0012] Preferably, the thermal insulation structure integrated steel-plastic anchor bolt in step 5 is vertically inserted into the steel bars of the cast-in-place shear wall. After the thermal insulation structure integrated steel-plastic anchor bolt is vertically inserted into the steel bars of the cast-in-place shear wall, when concrete is poured to form the cast-in-place shear wall, the thermal insulation structure integrated steel-plastic anchor bolt is vertically cast into the cast-in-place shear wall, thereby ensuring the tension of the cast-in-place shear wall on the insulation board.
[0013] Preferably, the independent support in step six is an axially retractable support frame. The axially retractable support frame is designed to facilitate axial retractable adjustment of the support frame to adapt to the beam-slab formwork, thereby ensuring the support function of the support frame on the beam-slab formwork. The axially retractable support frame can be two support rods, one of which has a screw at its end and an internal threaded hole at its end. The screw is threadedly connected to the internal threaded hole. The distance between the two support rods can be adjusted by adjusting the length of the screw extending into the internal threaded hole, thereby achieving axial retractable adjustment of the support frame.
[0014] Preferably, the joint treatment in step nine includes cleaning the joints, inserting Class A insulation blocks, inserting waterproof cavities, inserting foamed polyethylene rods, sealing with building weatherproof sealants, and installing finished Eps skirtings. Since there is slurry overflow at the joints between the non-disassembly insulation board and the prefabricated exterior wall during the construction of the main structure, the slurry at the joints is manually removed before the detailed construction of the joints. The cleaning of the joints is to ensure the effect of the subsequent sealing construction. Among them, Class A insulation blocks, waterproof cavities, foamed polyethylene rods, building weatherproof sealant sealing and finished Eps skirtings are all to ensure the sealing performance of the joints between the prefabricated components and the insulation boards, and to avoid water seepage along the joints between the prefabricated components and the insulation boards.
[0015] Preferably, the Class A insulation blocks, waterproof cavities, foamed polyethylene rods, building weatherproof sealant plugging, and finished EPS skirting are arranged in order from the inside out. That is, the junction of the non-removable insulation board and the prefabricated exterior wall is connected with a special adhesive, the waterproof cavity outside the insulation is sealed with foamed polyethylene rods and building weatherproof sealant, and the finished EPS skirting is installed on the prefabricated exterior wall near the insulation edge.
[0016] Preferably, in step nine, the contact area between the prefabricated component and the insulation board and the insulation board are pressed into the prefabricated component by at least 50 mm. The insulation board is pressed into the prefabricated component by at least 50 mm to leave enough space for the above-mentioned joint treatment between the prefabricated component and the insulation board to ensure the sealing performance of the joint between the prefabricated component and the insulation board.
[0017] Preferably, the protective treatment in step 10 includes applying an interface agent, applying cement waterproof mortar, pressing in an alkali-resistant glass fiber mesh, applying a primer, spraying a main layer of paint, and applying a decorative surface paint in sequence. The protective treatment of applying an interface agent, applying cement waterproof mortar, pressing in an alkali-resistant glass fiber mesh, applying a primer, spraying a main layer of paint, and applying a decorative surface paint in sequence greatly reduces the time it takes for the insulation board to be eroded by external factors, thereby increasing the service life of the insulation board.
[0018] Beneficial effects of the present invention: 1. In the construction method of this application, the insulation board is used as the exterior wall formwork that does not need to be dismantled, and the steel-plastic anchor bolts and bolts of the insulation structure integrated with the insulation board are directly cast into the concrete wall, forming an integrated connection between the insulation board and the cast-in-place shear wall, which greatly improves the fixing effect of the insulation board.
[0019] 2. The exterior wall of the cast-in-place part adopts the non-removal insulation board construction technology. The non-removal insulation board is applied to the outside of the exterior wall, and the aluminum formwork is used on the inside. The insulation board does not need to be removed after being cast together with the main body. The non-removal insulation board is used to replace the external formwork, which does not need to be removed later, thus solving the problem of difficult control of the exterior wall quality and saving the cost of external formwork rental, support and removal.
[0020] 3. During construction, except for the outer side of the exterior wall, non-removable insulation boards are used, and the rest of the cast-in-place parts are all made of aluminum alloy formwork. The aluminum alloy formwork has fast construction speed and good molding quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.
[0030] Example 1, a new type of construction method for the internal pouring and external splicing combination system of the heat preservation integrated panel without disassembly, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, it includes the following steps: Step 1: layout the insulation board 3 in sequence, make the steel formwork, and cut and assemble the insulation board 3; at the same time, produce and transport the prefabricated components 1 to the construction site; Step 2: draw the prefabricated component lines, cast-in-place shear wall column lines and wall column control lines on the floor; Step 3: hoist and fix the prefabricated components 1 to the corresponding layout positions; Step 4: tie the steel bars at the cast-in-place shear wall 2 and install the water and electricity pipelines; after tying the steel bars at the cast-in-place shear wall 2 and the water and electricity pre-buried pipelines, install the wall column aluminum formwork; Step 5: hoist the insulation board 3 and the steel formwork to the preset position. After the insulation board 3 is in place, the aluminum formwork on the inside and the insulation board 3 on the outside are bolted together. Secure the connection; drive the integrated steel-plastic anchor bolts of the insulation structure into the insulation board 3 through the anchor holes reserved on the insulation board 3; Step 6: Install the beam and slab formwork and independent support 4; Step 7: Tie the steel bars and install the water and electricity pipelines at the beam and slab; Hoist the composite slab and connect the composite slab to the steel bars at the beam and slab; Step 8: Pour concrete into the space between the aluminum formwork of the wall columns of the cast-in-place shear wall 2, the space between the aluminum formwork at the connection between the prefabricated component 1 and the cast-in-place shear wall 2, and the space between the inner aluminum formwork and the insulation board 3 on the outside; Step 9: Treat the joints between the insulation board 3 on the exterior wall and the prefabricated component 1 on the exterior wall; Step 10: Protect the insulation board 3 after construction is completed. In the construction method of the present application, the insulation board 3 is used as the exterior wall formwork that does not need to be dismantled, and the steel-plastic anchor bolts and bolts of the insulation structure integrated with the insulation board 3 are directly cast into the cast-in-place shear wall 2, forming an integrated connection between the insulation board 3 and the cast-in-place shear wall 2, which greatly improves the fixing effect of the insulation board 3 and solves the technical problem that the insulation board is connected to the cast-in-place shear wall through insulation connectors and steel wire mesh in the existing construction method, but is not directly connected to the cast-in-place shear wall as an integral whole, resulting in poor fixing effect of the insulation board.
[0031] The outer side of the insulation board 3 is installed with a steel formwork, and the loose insulation boards are assembled into the outer formwork of the overall exterior wall according to the size determined in the design drawing through the steel formwork. They are hoisted to the corresponding position of the floor and combined with the aluminum formwork on the inner side of the exterior wall to form a casting formwork for the exterior wall. This design effectively improves the molding quality of the exterior wall insulation board.
[0032] The exterior walls of the cast-in-place part adopt the non-removal insulation board construction technology. The non-removal insulation board is applied to the outside of the exterior wall, and the aluminum formwork is used on the inside. The insulation board does not need to be removed after being cast together with the main body. The non-removal insulation board is used instead of the external formwork, which does not need to be removed later, thus solving the problem of difficult control of the exterior wall quality and saving the cost of external formwork rental, support and removal.
[0033] During construction, except for the outer side of the wall, a non-removable insulation board 3 is used, and the rest of the cast-in-place parts are all made of aluminum alloy formwork. The aluminum alloy formwork has a fast construction speed and good molding quality.
[0034] Example 2, based on Example 1, a new type of construction method for the internal pouring and external splicing combination system of the heat preservation integrated panel without disassembly, such as Figure 1 and Figure 2 As shown, in step 3, the prefabricated components 1 are coded, and the prefabricated components 1 are hoisted in sequence according to the component codes. After the prefabricated components 1 are coded, it is convenient to quickly hoist the prefabricated components 1 to the corresponding positions according to the component codes, which is conducive to improving the installation efficiency of the prefabricated components 1.
[0035] Example 3, based on Example 1, a new type of construction method for the internal pouring and external splicing combination system of the heat preservation integrated panel without disassembly, such as Figure 1 and Figure 3 As shown, in step 4, when tying the steel bars, the exterior wall steel bars are tied first, followed by the interior wall steel bars. This means that when tying the wall column steel bars, the exterior wall steel bars are tied first, and plumbing and electrical installation are performed simultaneously with the steel bar tying. After the exterior wall steel bars and plumbing and electrical pipelines are installed, the insulation workers begin installing the exterior insulation board, while the reinforcement workers simultaneously tie the interior wall steel bars. This allows the plumbing and electrical installation to proceed simultaneously with the steel bar tying without affecting the overall progress.
[0036] Example 4, based on Example 1, a new type of construction method for the internal pouring and external splicing combination system of the heat preservation integrated panel without disassembly, such as Figure 1 As shown, in step five, concrete support bars and I-shaped steel bars are provided between the insulation board 3 and the aluminum formwork. The concrete support bars and I-shaped steel bars are both perpendicular to the steel bars at the cast-in-place shear wall 2. The provision of the concrete support bars and I-shaped steel bars is to ensure the thickness of the cast-in-place shear wall 2 and to avoid the situation where the thickness of the cast-in-place shear wall is insufficient due to excessive tightening between the insulation board 3 and the aluminum formwork. The concrete support bars and I-shaped steel bars are both perpendicular to the steel bars at the cast-in-place shear wall. This provision is to ensure that the size of the concrete support bars and I-shaped steel bars is the same as the thickness of the cast-in-place shear wall, so as to ensure the thickness of the cast-in-place shear wall.
[0037] Example 5, based on Example 4, a new type of construction method for the internal pouring and external splicing combination system of the heat preservation integrated panel without disassembly, such as Figure 1 As shown, the thermal insulation structure integrated steel-plastic anchor bolt in step 5 is vertically extended into the steel bar of the cast-in-place shear wall 2. After the thermal insulation structure integrated steel-plastic anchor bolt is vertically extended into the steel bar of the cast-in-place shear wall 2, when pouring concrete to form the cast-in-place shear wall 2, the thermal insulation structure integrated steel-plastic anchor bolt is vertically cast into the cast-in-place shear wall 2, ensuring the tension of the cast-in-place shear wall on the insulation board.
[0038] Example 6, based on Example 1, a new type of construction method for the internal pouring and external splicing combination system of the heat preservation integrated panel without disassembly, such as Figure 6As shown, the independent support 4 in step 6 is an axially retractable support frame. The axially retractable support frame is designed to facilitate axial retractable adjustment of the support frame to adapt to the beam-slab formwork, ensuring the support frame's supporting effect on the beam-slab formwork. The axially retractable support frame can be two support rods, one support rod having a screw at the end and the other support rod having an internal threaded hole at the end. The screw is threadedly connected to the internal threaded hole. The distance between the two support rods can be adjusted by adjusting the length of the screw extending into the internal threaded hole, thereby achieving axial retractable adjustment of the support frame.
[0039] Example 7, based on Example 1, a new type of construction method for the internal pouring and external splicing combination system of the heat preservation integrated panel without disassembly, such as Figure 5 As shown, the joint treatment in step nine includes cleaning the joints, inserting Class A insulation blocks 5, inserting waterproof cavities 6, inserting foamed polyethylene rods 7, sealing with building weatherproof sealant 8, and installing finished EPS skirtings 9. Since there is slurry overflow at the joints between the non-removal insulation board and the prefabricated exterior wall during the construction of the main structure, the slurry at the joints is manually removed before the detailed construction of the joints. The cleaning of the joints is to ensure the effect of the subsequent sealing construction. Among them, Class A insulation blocks 5, waterproof cavities 6, foamed polyethylene rods 7, sealing with building weatherproof sealant 8, and finished EPS skirtings 9 are all to ensure the sealing performance of the joints between the prefabricated components and the insulation boards, and to avoid water seepage along the joints between the prefabricated components and the insulation boards.
[0040] Example 8, based on Example 7, a new type of construction method for the internal pouring and external splicing combination system of the heat preservation integrated panel without disassembly, such as Figure 5 As shown, the Class A insulation block 5, waterproof cavity 6, foamed polyethylene rod 7, building weatherproof sealant plugging 8, and finished EPS skirting 9 are arranged in sequence from the inside to the outside. That is, the junction of the non-removal insulation board and the prefabricated exterior wall is connected with a special adhesive, the waterproof cavity 6 outside the insulation board is sealed with foamed polyethylene rod 7 and building weatherproof sealant 8, and the finished EPS skirting 9 is installed near the insulation edge of the prefabricated exterior wall.
[0041] Example 9, based on Example 8, a new type of construction method for the internal pouring and external splicing combination system of the heat preservation integrated panel without disassembly, such as Figure 5 As shown, in step nine, the contact area between the prefabricated component 1 and the insulation board 3 is such that the insulation board 3 is pressed at least 50 mm into the prefabricated component 1. The reason for pressing the insulation board 3 at least 50 mm into the prefabricated component 1 is to leave sufficient space for the aforementioned joint treatment between the prefabricated component 1 and the insulation board 3, thereby ensuring the sealing performance of the joint between the prefabricated component 1 and the insulation board 3. Preferably, the insulation board 3 is pressed 50 mm into the prefabricated component 1.
[0042] Example 10, based on Example 1, a new type of construction method for the internal pouring and external splicing combination system of the heat preservation integrated panel without disassembly, such as Figure 1As shown, the protective treatment in step 10 includes applying an interface agent, applying cement waterproof mortar, pressing in an alkali-resistant glass fiber mesh, applying a primer, spraying a main layer of paint, and applying a decorative topcoat. This protective treatment, which is performed from the inside out, of applying an interface agent, applying cement waterproof mortar, pressing in an alkali-resistant glass fiber mesh, applying a primer, spraying a main layer of paint, and applying a decorative topcoat, significantly reduces the time it takes for the insulation board to be eroded by external factors, thereby increasing the service life of the insulation board.
[0043] When Example 10 is implemented, Step 1: Layout the insulation board 3, make the steel formwork, cut and assemble the insulation board 3 in sequence; at the same time, produce and transport the prefabricated components 1 to the construction site; Step 2: Mark the prefabricated component lines, cast-in-place shear wall column lines and wall column control lines on the floor; Step 3: hoist and fix the prefabricated component 1 to the corresponding setting-out position; Step 4: Tie up the steel bars at the cast-in-place shear wall and install the water and electricity pipelines; After tying up the steel bars at the cast-in-place shear wall and the embedded water and electricity pipelines, install the wall column aluminum formwork; Step 5: Hoist the insulation board 3 and the steel formwork to the preset position. After the insulation board 3 is in place, reinforce the inner aluminum formwork and the outer insulation board 3 with bolts; drive the insulation structure integrated steel-plastic anchor bolts into the insulation board 3 through the anchor bolt holes reserved on the insulation board 3; Step 6: Install beam and slab formwork and independent support 4; Step 7: Tie the steel bars and install the water and electricity pipelines at the beam and slab; hoist the composite slab and connect it to the steel bars at the beam and slab; Step 8: Pour concrete into the space between the aluminum formworks of the cast-in-place shear wall 2 columns, the space between the aluminum formworks at the connection between the prefabricated component 1 and the cast-in-place shear wall 2, and the space between the inner aluminum formwork and the outer insulation board 3.
[0044] Step 9: Perform joint treatment on the joints between the insulation board 3 on the exterior wall and the prefabricated components 1 of the exterior wall; Step 10: After the construction of the insulation board 3 is completed, the insulation board 3 is protected.
[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
