Description

Technical Field

[0001] This application relates to the technical field of building exterior walls, and in particular to a cast-in-place exterior wall based on insulation board and its construction process. Background Technology

[0002] Currently, in order to achieve the effect of "insulating heat in winter and insulating heat in summer", insulation boards are usually installed on the exterior walls of buildings. The insulation boards block the heat exchange between the interior and exterior, thereby achieving the effect of heat insulation.

[0003] Currently, the infill walls of building exteriors in my country are mostly constructed using masonry blocks, followed by external insulation. This type of wall has poor overall performance, is prone to cracking, and is time-consuming, labor-intensive, costly, and inefficient to construct.

[0004] To shorten the construction period, in the existing technology, after the steel reinforcement cage is tied, formwork and insulation board are built on both sides of the steel reinforcement cage. The insulation board is set on the outside and fixed to the formwork through a connecting mechanism. At this time, a concrete pouring cavity is formed between the formwork and the insulation board. Then, concrete is poured into the concrete pouring cavity and cured. The formwork is removed after the concrete strength reaches the demolding standard.

[0005] Because the existing connection mechanism usually consists of a tie rod and a nut threaded to the tie rod, holes need to be made on both the insulation board and the template for the tie rod to pass through. This results in many thermal bridges at the connection mechanism during subsequent use, which leads to a shortened service life of the insulation board and a decrease in the thermal insulation performance of the cast-in-place exterior wall. Therefore, further improvements are needed. Summary of the Invention

[0006] In order to reduce the possibility of thermal bridging in the insulation board, thereby extending its service life and improving the insulation effect of the cast-in-place exterior wall, this application provides a cast-in-place exterior wall based on the insulation board and its construction process.

[0007] This application provides a cast-in-place exterior wall based on insulation board and its construction process, which adopts the following technical solution: A cast-in-place exterior wall based on insulation boards includes a reinforcing cage, insulation boards and formwork respectively disposed on both sides of the reinforcing cage, a connecting mechanism for connecting the insulation boards to the reinforcing cage, a support for the insulation boards and formwork, and cast-in-place concrete poured into a casting cavity formed between the insulation boards and formwork. The connecting mechanism includes an installation rod for sliding connection of the insulation boards, a fixing member for fixing the insulation boards to the installation rod, and a connecting assembly for installing the installation rod to the reinforcing cage. The length direction of the installation rod is parallel to the length direction of the reinforcing cage, and several installation rods are spaced apart along the height direction of the reinforcing cage. The inner surface of the insulation board has a sliding groove for sliding connection of the installation rod, the sliding groove extends to the two opposite inner sidewalls of the insulation board, and a limiting groove is formed on the opposite inner surface of the sliding groove. The installation rod is provided with a limiting block that slides into the limiting groove. Several insulation boards are provided along both the height and length directions of the reinforcing cage, and adjacent insulation boards abut against each other.

[0008] By adopting the above technical solution, the insulation board is slidably connected to the installation rod, and adjacent insulation boards abut against each other. The insulation board is then fixed to the installation rod using fasteners. Next, the installation rod is installed onto the reinforcing cage using connecting components, thus installing the insulation board onto the reinforcing cage. The installation rod and the sliding groove in the insulation board for the installation rod to slide and connect reduce the possibility of holes being made in the insulation board during the installation of the formwork using tie rods. This reduces the possibility of thermal bridging at these holes, extends the service life of the insulation board, and improves the insulation effect of the cast-in-place exterior wall.

[0009] Preferably, the reinforcing cage includes a plurality of vertically arranged first reinforcing bars and a plurality of horizontally arranged second reinforcing bars. The second reinforcing bars are fixedly connected to the first reinforcing bars and are wound around the first reinforcing bars. The connecting assembly includes a connecting plate disposed at one end of the mounting rod away from the insulation board and an adjusting member for adjusting the height of the connecting plate. The connecting plate is L-shaped and includes a horizontally arranged horizontal portion and a vertical portion perpendicular to the horizontal portion, so that the connecting plate is hung on the second reinforcing bars.

[0010] By adopting the above technical solution, during the binding process of the reinforcing cage, the spacing between adjacent first reinforcing bars will actually be different. Therefore, when the installation rods are hung on the first reinforcing bars through connecting plates and installed on the first reinforcing bars through connecting components, the spacing between adjacent installation rods will be different. This may result in the two rows of insulation boards not abutting each other or overlapping, thus affecting the subsequent concrete pouring and the flatness between adjacent rows of insulation boards, i.e., affecting the appearance of the insulation boards. Therefore, by setting up adjusting components to change the height of adjacent installation rods, the adjacent insulation boards can abut each other, thereby improving the insulation effect of the cast-in-place exterior wall and also improving the appearance of the insulation boards.

[0011] Preferably, the adjusting member includes a first adjusting block abutting against the lower surface of the horizontal part and a second adjusting block abutting against the side wall of the vertical part. A binding strap is threaded through the first adjusting block, and the second adjusting block and the connecting plate are both provided with through holes for the binding strap to pass through.

[0012] By adopting the above technical solution, when the upper row of insulation boards and the lower row of insulation boards are staggered, the height can be adjusted as needed. A first adjusting block of the corresponding height is placed between the horizontal part and the second reinforcing bar, abutting against the lower surface of the horizontal part, so that the surfaces of the two rows of insulation boards come into contact, thereby changing the height position of the insulation boards. The horizontal displacement can also be adjusted as needed. A second adjusting block of the corresponding width is placed between the vertical part and the second reinforcing bar, abutting against the surface of the vertical part near the mounting rod, thereby changing the horizontal position of the upper row of insulation boards. This reduces the possibility of staggering between the two rows of insulation boards, ensuring that the outer surfaces of the insulation boards between adjacent rows are flush. This improves the insulation effect on the cast-in-place exterior wall while also enhancing the appearance of the insulation boards.

[0013] Preferably, the outer surfaces of the first adjusting block and the second adjusting block are provided with first toothed grooves, and the surfaces of the horizontal part and the vertical part near the second reinforcing bar are provided with second toothed grooves. The first toothed groove engages with the second toothed groove. The length direction of the first toothed groove is parallel to the length direction of the second reinforcing bar. The through holes provided on the first adjusting block and the second adjusting block are all provided with waist-shaped holes.

[0014] By adopting the above technical solution, since relative slippage may occur between different first and second adjusting blocks during the process, the slippage can be restricted by setting the first and second tooth grooves, thereby reducing the possibility of relative collision between the first and second adjusting blocks.

[0015] Preferably, the adjusting component further includes a third adjusting block slidably connected to the connecting plate, a sliding plate abutting against the second reinforcing bar to allow the third adjusting block to slide, and a limiting part to restrict the sliding of the third adjusting block; the upper surface of the third adjusting block is provided with a first guide surface, which is inclined downward close to the template; the lower surface of the vertical part is provided with a second guide surface slidably connected to the first guide surface; the two ends of the sliding plate abut against the insulation board and the template, respectively; the width of the vertical part is greater than the width of the horizontal part; and a limiting plate protruding from the sliding plate abuts against the side wall of the vertical part.

[0016] By adopting the above technical solution, the third adjusting block is slidable to adjust the spacing between the upper and lower rows of insulation boards. After adjustment, a limiting component is used to limit the height adjusted. Furthermore, by having both ends of the sliding plate abut against the insulation board and the template respectively, the two formed pouring spaces are limited. The reinforced first guide surface is inclined downwards near the template, allowing the connecting block to rise as the third adjusting block slides towards the template. Due to the abutment between the first and second guide surfaces, the insulation board moves towards the sliding plate, abutting against it, reducing the possibility of gaps between the insulation board and the sliding plate, thus ensuring that the insulation boards in adjacent rows are staggered. The limiting plate further reduces the possibility of the connecting plate moving away from the sliding plate during the height adjustment process of the third adjusting block.

[0017] Preferably, each of the two adjacent insulation boards has a protruding convex plate that abuts against each other. The adjusting component also includes a drive rod rotatably connected to the third adjusting block. The length direction of the drive rod is parallel to the length direction of the sliding plate. The drive rod is exposed outside the reinforcing cage. The drive rod has an installation groove for installing the limiting part. The limiting part includes a spring fixedly connected to the inner wall of the installation groove and a limiting block fixedly connected to the spring. The sliding plate has limiting holes for the limiting block to slide and insert. Several limiting holes are spaced apart along the length direction of the sliding plate. The spring forces the limiting block to move towards the limiting hole.

[0018] By adopting the above technical solution, a drive rod is provided, which is exposed outside the reinforcing cage, so as to pull the third adjusting block to slide along the sliding plate, reducing the possibility of the third adjusting block being unable to slide due to the influence of the reinforcing cage. When the adjusted height is appropriate, the drive rod is rotated so that the limiting block is moved towards the limiting hole by the spring force, so as to be inserted into the limiting hole and limit the drive rod, thereby restricting the sliding of the third adjusting block and fixing the height of the insulation board.

[0019] Preferably, the end of the drive rod away from the third adjusting block is threaded, the drive rod is provided with a nut threaded to the thread, the template is provided with a through hole for the drive rod to pass through, and the nut abuts against the template.

[0020] By adopting the above technical solution, since the free end of the drive rod may be exposed on the sliding plate when the third adjusting block is pulled to slide along the sliding plate, affecting the subsequent installation of the template, the free end of the drive rod is threaded and a through hole is made on the template so that the excess drive rod can be threaded through the through hole and connected to the nut to connect with the template. This reduces the need for other installation parts to install the template and the reinforcing cage, and also restricts the drive rod from rotating due to external forces.

[0021] Preferably, the sliding plate has a guide groove communicating with the limiting hole. When the drive rod rotates clockwise, it drives the limiting block to move along the guide groove toward the limiting hole. The thread is a right-hand thread.

[0022] By adopting the above technical solution and setting a guide groove, the possibility of the limiting block being inserted into the corresponding limiting hole before being properly adjusted is reduced. It also facilitates height adjustment after multiple insulation boards are installed. After adjustment, the perforation on the template is aligned with the drive rod so that the drive rod passes through the perforation. It should be noted that since rotating the nut may cause the drive rod to rotate as well, the thread on the drive rod is set to a right-hand thread. Because it is compatible with the nut, the nut is also a right-hand nut. This ensures that rotating the nut, even when driving the drive rod, results in forward rotation, reducing the possibility of the limiting rod moving out of the limiting hole when the nut is rotated.

[0023] In summary, this application has the following beneficial effects: 1. By setting up installation rods, the possibility of holes being made in the insulation board when installing the formwork by inserting tie rods through the installation rods is reduced, thereby reducing the possibility of thermal bridging in the insulation board at these holes, extending the service life of the insulation board and improving the insulation effect of the cast-in-place exterior wall.

[0024] 2. By setting up adjustment components, the spacing between the installation rods can be adjusted so that adjacent insulation boards can abut against each other, thereby improving the insulation effect of the cast-in-place exterior wall and also improving the appearance of the insulation board.

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail below.

[0028] This application discloses a cast-in-place exterior wall based on insulation board and its construction process.

[0029] Example 1: A cast-in-place exterior wall based on insulation board, referring to Figure 1 , Figure 2 It includes a steel cage 1, insulation boards 2 and templates 3 respectively set on both sides of the steel cage 1, a connecting mechanism 4 for connecting the insulation boards 2 to the steel cage 1, a support member 5 for supporting the insulation boards 2 and templates 3, and cast-in-place concrete (not shown in the figure) poured into the casting cavity formed between the insulation boards 2 and templates 3.

[0030] The steel cage 1 includes several vertically arranged first steel bars 11 and several horizontally arranged second steel bars 12. It should be noted that in this embodiment, the second steel bars 12 are fixedly connected to the first steel bars 11, specifically by welding the two together for fixation.

[0031] In this embodiment, several insulation boards 2 are provided along both the height and length directions of the reinforcing cage 1, and adjacent insulation boards 2 abut against each other. Specifically, there are two insulation boards 2 along the height direction of the reinforcing cage 1 and three along the length direction of the reinforcing cage 1.

[0032] The connecting mechanism 4 includes an installation rod 41 for sliding connection of the insulation board 2, a fixing member (not shown in the figure) for fixing the insulation board 2 to the installation rod 41, and a connecting assembly 7 for installing the installation rod 41 to the reinforcing cage 1. Specifically, in this embodiment, the length direction of the installation rod 41 is parallel to the length direction of the reinforcing cage 1, and several installation rods 41 are spaced apart along the height direction of the reinforcing cage 1. The number of installation rods 41 is determined according to the height of the reinforcing cage 1 and the number of insulation boards 2 required according to the height of one exterior wall. In this embodiment, two installation rods 41 are provided along the height direction of the reinforcing cage 1. Correspondingly, a first sliding groove 21 is provided on the inner surface of the insulation board 2 for sliding connection of the installation rod 41. The first sliding groove 21 extends to the two opposite inner side walls of the insulation board 2, and a limiting groove 22 is provided on the opposite side walls of the first sliding groove 21. A limiting rod 411 protrudes and is fixedly connected to the limiting groove 22 on the opposite side walls of the installation rod 41. Therefore, three insulation boards 2 are provided on one installation rod 41.

[0033] Reference Figure 2 , Figure 3 It should be noted that, further, in order to reduce the gap between adjacent insulation boards 2, in this embodiment, each adjacent insulation board 2 is provided with a protruding and mutually abutting convex plate 23. Specifically, the convex plates 23 are respectively provided on the opposite side walls of the insulation board 2 and on the opposite end faces of the insulation board 2. The convex plates 23 on the adjacent rows of insulation boards 2 abut against each other, so that the abutting position between the two convex plates 23 is arranged in a Z-shape. Since there are two rows, no convex plates 23 are provided at the edge of the insulation board 2.

[0034] The fastener can be adhesive, which fills the first groove 21 to fix the insulation board 2 and the mounting rod 41, or it can be a cable tie, which is fixed by having through holes 81 on the insulation board 2 and the mounting rod 41 for the cable tie to pass through. The choice is made according to the requirements. In this embodiment, the fastener is adhesive.

[0035] Reference Figure 2, Figure 4 The connecting assembly 7 includes a connecting plate 71 disposed at the end of the mounting rod 41 away from the insulation board 2, and an adjusting member 72 for adjusting the height of the connecting plate 71. In this embodiment, the connecting plate 71 is L-shaped, and several connecting plates 71 are spaced apart along the length of the mounting rod 41, specifically two, which are respectively disposed near both ends of the mounting rod 41. Specifically, the connecting plate 71 includes a horizontal part 711 disposed horizontally and a vertical part 712 disposed perpendicular to the horizontal part 711. The vertical part 712 is disposed below the horizontal part 711 so that the connecting plate 71 is hung on the second reinforcing bar 12.

[0036] Reference Figure 4 , Figure 5 The adjusting member 72 includes a first adjusting block 721 that abuts against the lower surface of the horizontal part 711 and a second adjusting block 722 that abuts against the side wall of the vertical part 712. A binding strap 8 is threaded through the first adjusting block 721, and both the second adjusting block 722 and the connecting plate 71 have through holes 81 for the binding strap 8 to pass through.

[0037] Referring to the figure, further, in order to reduce the possibility of slippage and disengagement of the first adjusting block 721 and the second adjusting block 722, in this embodiment, the outer surfaces of the first adjusting block 721 and the second adjusting block 722 are provided with first toothed grooves, and the surfaces of the horizontal part 711 and the vertical part 712 near the second reinforcing bar 12 are provided with second toothed grooves. The first toothed grooves engage with the second toothed grooves, and the length direction of the first toothed grooves is parallel to the length direction of the second reinforcing bar 12. The through holes 81 provided on the first adjusting block 721 and the second adjusting block 722 are all provided with waist-shaped holes.

[0038] Among them, the support member 5 is the support keel 51 and the support rod 52, which is a common method in the prior art, and will not be described in detail here.

[0039] The implementation principle of a cast-in-place exterior wall based on insulation board in this application embodiment is as follows: a second reinforcing bar 12 is wound around several first reinforcing bars 11 and welded to the first reinforcing bars 11. Several insulation boards 2 are slidably connected to the mounting rod 41. At this time, adjacent insulation boards 2 abut against each other, and adhesive is filled into the first sliding groove 21 to fix the insulation board 2 and the mounting rod 41. After fixing, the connecting rod set on the mounting rod 41 is hung on the second reinforcing bar 12. When there is a gap between the second reinforcing bar 12, the corresponding first adjusting block 721 and second adjusting block 722 are placed in the horizontal part 711 and the vertical part 712 to adjust the gap between the connecting plate 71 and the second reinforcing bar 12. When installing the insulation board 2 of the previous row, the adjusting member 72 is used to adjust its height so that it abuts against the insulation board 2 of the next row.

[0040] After the insulation board 2 is installed, it is supported by the support member 5, and the template 3 is installed on the inside of the steel cage 1 and supported by the support member 5 before pouring concrete.

[0041] This application also discloses a construction process for cast-in-place exterior walls based on insulation boards, including the following steps: S1: Install steel cage 1: S2: Install insulation board 2: Several insulation boards 2 are slidably connected to the mounting rod 41. At this time, the adjacent insulation boards 2 abut against each other. The mounting rod 41 is installed on the outside of the steel cage 1 through the connecting component 7 and supported by the support member 5. S3: Formwork support: The template 3 is placed inside the steel cage 1 and supported by the support member 5, so that the template 3 and the insulation board 2 form a concrete pouring cavity. S4: Pour concrete into the concrete casting mold cavity and cure it. After the concrete strength reaches the demolding standard, proceed to the next step. S5: Remove formwork 3. At this time, insulation board 2 and the poured concrete form an outer wall with insulation board 2.

[0042] Example 2: Reference Figure 6 , Figure 7 The difference from Embodiment 1 is that the adjusting member 72 further includes a third adjusting block 723 slidably connected to the lower surface of the connecting plate 71, a sliding plate 724 abutting against the second reinforcing bar 12 to allow the third adjusting block 723 to slide, a driving rod 725 rotatably connected to the third adjusting block 723, and a limiting part 726 restricting the sliding of the third adjusting block 723. The third adjusting block 723 is slidably connected to the lower end face of the vertical part 712. In this embodiment, the upper surface of the third adjusting block 723 has a first guide surface 9, which is inclined downwards near the template 3. The lower surface of the vertical part 712 has a second guide surface 91 slidably connected to the first guide surface 9.

[0043] In this embodiment, the length of the sliding plate 724 is longer than the width of the overall reinforcing cage 1, and both ends of the sliding plate 724 are exposed outside the reinforcing cage 1. For the installation of the sliding plate 724, a groove 7241 is provided on the lower end face of the sliding plate 724. When the second reinforcing bar 12 is wound around the first reinforcing bar 11 and welded, when the height of the second reinforcing bar 12 is about the same as the height of the connecting plate 71, the sliding plate 724 is first placed on the second reinforcing bar 12 so that the second reinforcing bar 12 is embedded in the groove 7241. The height of the sliding plate 724 at this time is pre-positioned. Then the second reinforcing bar 12 is installed to complete the installation of the overall reinforcing cage 1. When it is determined that the height and horizontal height of the sliding plate 724 are about the same as the connecting plate 71, the sliding plate 724 is then welded to the second reinforcing bar 12 to reduce the possibility of relative slippage. Furthermore, the two ends of the sliding plate 724 abut against the insulation board 2 and the template 3 respectively, so as to control the size of the pouring space formed between the insulation board 2 and the template 3.

[0044] Regarding the sliding of the third adjusting block 723, specifically, a slider is fixedly protruding from the lower end face of the third adjusting block 723, and a second sliding groove 7242 is provided on the upper surface of the sliding plate 724 for the slider to slide and connect. In this embodiment, the slider is set in a T-shape and is set in a T-shape relative to the second sliding groove 7242. The slider is slidably connected to the second sliding groove 7242 so that the third adjusting block 723 is slidably connected to the sliding plate 724.

[0045] Reference Figure 7 , Figure 8 The drive rod 725 is parallel to the length of the sliding plate 724 and protrudes from the reinforcing cage 1 to allow operation of the drive rod 725 to slide the third adjusting block 723. The drive rod 725 has an installation groove 7251 for mounting the limiting part 726. The limiting part 726 includes a spring 7261 fixedly connected to the inner wall of the installation groove 7251 and a limiting block 7262 fixedly connected to the spring 7261. The sliding plate 724 has a limiting hole 7243 for the limiting block 7262 to slide and insert. Several limiting holes 7243 are spaced apart along the length of the sliding plate 724. In this embodiment, the spring 7261 forces the limiting block 7262 to move closer to the limiting hole 7243 to limit the sliding of the drive rod 725, thereby limiting the sliding of the third adjusting block 723.

[0046] Furthermore, in order to reduce the possibility of the connecting plate 71 sliding off the third adjusting block 723, in this embodiment, the width of the horizontal part 711 near the vertical part 712 is greater than the width near the insulation plate 2, and a limiting plate 7244 protruding from the sliding plate 724 abuts against the side wall of the horizontal part 711, so as to limit the possibility of the connecting plate 71 sliding off the third adjusting block 723.

[0047] Reference Figure 9 Furthermore, since the drive rod 725 is exposed outside the steel cage 1, when the third adjusting block 723 is slidable, the free end of the drive rod 725 may be longer than the sliding plate 724. At this time, the end of the drive rod 725 away from the third adjusting block 723 is provided with a thread 7252, and the drive rod 725 is provided with a nut 7253 connected to the thread 7252. The template 3 is provided with a through hole 31 for the drive rod 725 to pass through, and the nut 7253 abuts against the template 3 to strengthen the connection strength between the template 3 and the insulation board 2 through the connecting assembly 7.

[0048] Back Figure 7 It should be noted that, in order to reduce the need to adjust the height of the insulation board 2 later, the sliding plate 724 is provided with a guide groove 7245 that communicates with the limiting hole 7243. The guide groove 7245 is set on one side close to the sliding plate 724. Specifically, in this embodiment, when the drive rod 725 rotates clockwise, it drives the limiting block 7262 to move along the guide groove 7245 toward the direction close to the limiting hole 7243. The thread 7252 set on the drive rod 725 is a right-hand thread 7252, so that the nut 7253 is a right-hand nut 7253, so as to reduce the possibility of the limiting block 7262 sliding out of the limiting hole 7243 when the nut 7253 is rotated.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
