Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a cast-in-place lightweight wall formwork assembly process based on a secondary structure and a formwork system thereof. Background Art

[0002] In the construction of building structures, secondary structures are non-load-bearing or enclosure structures. They are constructed immediately after the main load-bearing structure (primary structure) is completed. They include key elements such as structural columns, lintels, water-stopping beams, parapets, capping, infill walls and partitions. They need to be constructed in advance before the decoration project. Although the secondary structure does not directly bear the main load of the building, it is crucial to ensure the overall structural integrity, stability and aesthetic appearance of the building.

[0003] However, the current practice of cast-in-place secondary structure technology faces significant challenges, mainly in the following aspects:

[0004] 1. Lack of precision and standards: Existing technologies are limited by the basic conditions of the primary structure, and the cast-in-place operation of the secondary structure often fails to meet the high standards of flatness and verticality without plastering. The construction of the primary structure is often carried out in an open environment, lacking precise control, while the casting of the secondary structure needs to be carried out under the indoor beam or slab, with limited space, which puts higher requirements on the height of the formwork, the flatness and verticality of the connection with the existing structure, and requires the fullness and height of the wall to be accurate and correct. Existing technologies are difficult to meet these high standards.

[0005] 2. High material costs: Traditional formwork support technology uses a large amount of materials, not only horizontal and vertical reinforcement materials, but also various accessories required for formwork splicing, which leads to a significant increase in material costs. This high-consumption model not only increases the project budget burden, but also violates the sustainable development concept of green buildings.

[0006] 3. Low efficiency: Due to the large amount of materials used, the mold assembly and demolding process becomes complicated and time-consuming, requiring a lot of manpower, which seriously affects the efficiency of formwork assembly and overall pouring. The cumbersome mold assembly and demolding process not only prolongs the construction period, but also increases labor costs and reduces the overall economic benefits of the construction.

[0007] To sum up, the existing secondary structure cast-in-place technology has problems such as poor versatility, high cost, and large waste of materials in the secondary structure cast-in-place process. The existing secondary structure cast-in-place technology has obvious deficiencies in precision control, cost control and construction efficiency. Technological innovation is urgently needed to overcome these bottlenecks and promote the development of construction technology towards a more efficient, economical and environmentally friendly direction.

[0008] Therefore, the prior art needs to be further developed. Summary of the invention

[0040] Furthermore, the height of the bottom angle steel is 5 cm to 15 cm, and the assembly process also includes:

[0041] When there is an error in the height of the wall formed by the mold, the height adjustment device is used to adjust the height adjustment device so that the bottom of the template does not exceed the highest point of the bottom angle steel to correct the height of the template.

[0042] A formwork system is assembled by the above-mentioned assembly process. The formwork system is spliced ​​by several groups of formworks enclosed on both sides of the wall.

[0044] Furthermore, the extended square steel is formed by splicing the standard square steel and the extended structure, and the extended structure is slidably connected to the inner cavity of the standard square steel.

[0045] Beneficial effects:

[0046] 1. It can be understood that, by adopting the assembly process in this embodiment, the specifications of the square steel are determined according to the drawings before assembly, and the installation plan of the square steel is selected. During the pre-assembly process, the standard plate formwork is assembled into a standard plate formwork group. During the mold closing process, the standard plate formwork group is directly assembled, and the fastest square steel installation plan that matches the wall is selected. The process and steps of installing the formwork are simplified, the consumables consumed in the assembly process are reduced, and the support materials and assembly time are reduced, thereby improving the efficiency of formwork assembly, and solving the technical problems of poor versatility, high cost and large waste of materials in the traditional building formwork process in the related technology during the cast-in-place process of the secondary structure.

[0047] 2. Specifically, the square steel, which is the most commonly used building material in cast-in-place lightweight wall formwork, is standardized, and the square steel is customized according to the common indoor wall height. For example, common heights such as 2.35m and 2.65m can be selected to improve the versatility of the square steel. During the assembly process, if the height of the wall matches the standard square steel, the standard square steel is directly used. If it does not match, an extension structure is used to extend the standard square steel. This can reduce the use of consumables generated by splicing, simplify the assembly process, and improve the efficiency of formwork assembly.

[0048] 3. In the process of forming the standard plate formwork group, a certain number of standard plates are selected for assembly according to the length of the wall. The standard plate group is aligned and connected according to the installation drawing, and assembled in the assembly form of "one side of the square steel is the tie angle steel, and the other side is fixed with screws" to form a standard plate formwork group. The above-mentioned assembly form not only reduces the assembly time of mold closing, but also in the process of demolding, there is no need to disassemble the standard plates one by one according to the traditional process. Multiple standard plates can be disassembled together as a combination at the same time. When used next time, the combination of multiple standard plates can be directly used. This not only improves the speed of assembly and demolding, but also saves the labor of transportation after demolding, improves the efficiency of assembly, and further improves the overall construction efficiency.

[0049] 4. In the cast-in-place lightweight wall formwork assembly process based on secondary structure in this embodiment, the adjustment area is lengthened. In addition to completing the basic function of height calibration, when there is a large gap between the formwork height and the beam or ceiling, the height of the formwork is further adjusted by the height calibration equipment, thereby achieving the purpose of quickly solving the height error, improving the assembly efficiency, solving the problem of multiple template matching caused by height differences in indoor formwork, and meeting the high flexibility requirements of the secondary structure formwork.

[0071] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0072] According to an embodiment of the present invention, a cast-in-place lightweight wall formwork assembly process based on a secondary structure is provided. Figures 1 to 19 ,include:

[0073] S1: Lay out the lines according to the drawings and install the positioning ribs and bottom angle steel 11;

[0074] S2: Determine the specifications of the square steel 4 according to the drawing and select the installation plan of the square steel 4;

[0075] S3: Install the standard plate template to form a standard plate template group 5, install the internal angle plate template 3 and the plugging plate template 6;

[0076] S4: Splice the internal angle plate template 3, the standard plate template group 5, and the plugging plate template 6, and install the three-stage water-stop tension screw 2 on the inner side of the templates on both sides of the mold according to the designed wall thickness, which is used for positioning and pulling the wall thickness, and complete the installation of the mold;

[0077] S5: After the mold is closed, vertical and horizontal reinforcement is performed on the outside of the formwork to complete the assembly of the cast-in-place lightweight wall formwork.

[0078] It can be understood that, by adopting the assembly process in this embodiment, the specifications of the square steel 4 are determined according to the drawings before assembly, and the installation plan of the square steel 4 is selected. During the pre-assembly process, the standard plate formwork is assembled into a standard plate formwork group 5, and during the mold closing process, the standard plate formwork group 5 is directly assembled, and the fastest square steel installation plan that matches the wall is selected, which simplifies the process and steps of installing the formwork, reduces the consumables consumed in the assembly process, reduces the support materials and assembly time, thereby improving the efficiency of the formwork assembly, and solves the technical problems of poor versatility, high cost and large waste of materials in the traditional building formwork process in the related technology during the cast-in-place process of the secondary structure.

[0079] In the cast-in-place lightweight wall formwork assembly process based on the secondary structure of this embodiment, the steps of determining the specifications of the square steel 4 according to the drawings and selecting the installation scheme of the square steel 4 include:

[0080] S2.1.1: Based on the wall height marked on the drawing, if the wall height matches the standard square steel 41, the standard square steel 41 shall be used;

[0081] S2.1.2: If the height of the wall is greater than the standard square steel 41, the extended square steel 42 is selected and the specifications of the extended structure 421 forming the extended square steel 42 are determined.

[0082] Specifically, the square steel 4, which is the most commonly used building material in the cast-in-place lightweight wall formwork, is standardized, and the square steel 4 is customized according to the common indoor wall height. For example, common heights such as 2.35m and 2.65m can be selected to improve the versatility of the square steel 4. During the assembly process, if the height of the wall matches the standard square steel 41, the standard square steel 41 is directly used. If it does not match, the extension structure 421 is used to extend the standard square steel 41. This can reduce the use of consumables generated by splicing, simplify the assembly process, and improve the efficiency of the formwork assembly.

[0083] In the cast-in-place lightweight wall formwork assembly process based on the secondary structure of this embodiment, see Figure 1 The standard plate template group 5 includes at least two standard templates, the at least two standard plate templates include a first template 51 and a second template 52 spliced ​​to each other, and the square steel 4 includes a standard square steel 41 and an extended square steel 42 to form the standard plate template group 5. The steps include:

[0084] S3.1.1: Use a positioning tool to install the tie angle steel 13 at the top of the right edge of the first template 51, install the square steel 4 at the right edge of the first template 51, install the standard square steel 41 or form the extended square steel 42 according to the drawing, and fix and tighten the square steel 4 and the tie angle steel 13 at the top of the right edge of the first template 51 through the clamp 12;

[0085] S3.1.2: Use a positioning tool to install the tie angle steel 13 at the middle and bottom of the right edge of the first template 51, so that the square steel 4 and the tie angle steel 13 at the bottom and middle of the right edge of the first template 51 are fixed and tightened by the seam clamp 12;

[0086] S3.1.3: Align the second template 52 with the first template 51 that has been installed, and fix the square steel 4 located on the right edge of the first template 51 to the second template 52 by fixing screws at the top, middle and bottom of the left edge of the second template 52;

[0087] S3.1.4: The first and last standard plates of the standard plate template group 5 are both installed with the positioning tool to install the tie angle steel 13 at the top, middle and bottom of the side where the square steel 4 is not installed;

[0088] S3.1.5: Complete the splicing of the remaining standard panel formwork along the entire length of the wall.

[0089] It is understandable that the square steel 4 can also be installed on the left side of the first template 51 according to the orientation or structure of the wall. In other words, the assembly form of "one side of the square steel 4 is the tie angle steel 13, and the other side is screwed" can be applied to the template assembly of any wall structure.

[0090] Specifically, the standard board formwork adopts non-standard customized board, which is customized according to the common indoor wall height, such as 1.9m, 2.3m and other common heights, to improve the versatility of the non-standard customized version. During the assembly process, there is no need to use too many templates for splicing, thereby reducing the generation of splicing seams, solving the problem of wall flatness after demolding, and improving the flatness and verticality of the wall.

[0091] In some embodiments, the first set of screws is fixed at one quarter of the square steel 4, and the remaining screws are distributed according to the length of the square steel.

[0092] Specifically, in the process of forming the standard plate formwork group 5, a certain number of standard plates are selected for assembly according to the length of the wall, the standard plate group is aligned and connected end to end according to the installation drawing, and assembled in accordance with the assembly form of "one side of the square steel 4 is the tie angle steel 13, and the other side is fixed with screws", thereby forming the standard plate formwork group 5.

[0093] It can be understood that, by using the tie angle steel 13 for fixing, the strength of the template where the tie angle steel 13 is located can be increased.

[0094] The above-mentioned assembly form not only reduces the assembly time of the mold, but also during the demolding process, there is no need to disassemble the standard plates one by one according to the traditional process. Multiple standard plates can be disassembled together as a combination at the same time. When used next time, the combination of multiple standard plates can be directly used. This not only improves the speed of assembly and demolding, but also saves the labor of transportation after demolding, improves the efficiency of assembly, and thus further improves the overall construction efficiency.

[0095] It is understandable that the primary structure is cast in the open air without a ceiling, and the secondary structure cast-in-place technology is to cast the non-load-bearing walls under the beams or slabs. Therefore, the walls and area of ​​the secondary structure are smaller than the walls of the primary structure. Whether it is customized non-standard formwork or using standard plate formwork group 5 for disassembly and assembly, the difficulty and cost are less than the use cost and installation and transportation difficulty of the formwork of the primary structure.

[0096] In the cast-in-place lightweight wall formwork assembly process based on the secondary structure of this embodiment, see Figure 2-4 The steps of forming the extended square steel 42 include:

[0097] S3.1.1.1: Insert the extension structure 421 into the inner cavity of the standard square steel 41;

[0098] S3.1.1.2: And adjust the height of the extension structure 421 to a suitable position according to the drawings;

[0099] S3.1.1.3: Fix the extension structure 421 to the standard square steel 41 to form the extended square steel 42.

[0100] It should be noted that the square steel 4, the most commonly used building material in the template, is standardized and customized according to the common indoor wall height, such as common heights such as 2.35m and 2.65m, to improve the versatility of the square steel 4. During the assembly process, if the height of the wall matches the standard square steel 41, the standard square steel 41 is directly used. If the square steel 4 needs to be extended, the extension structure 421 can be used. The position of the extension structure 421 can be adjusted by pulling the extension structure 421, thereby adjusting the length of the extended square steel 42, which can reduce the use of consumables generated by splicing, simplify the assembly process, and improve the efficiency of the template assembly.

[0101] It is understandable that by customizing standard square steels of universal length and matching extension structures 421 with standard square steels 41 of various specifications, various length combinations of square steels 4 can be achieved, which can fully meet the use requirements of square steels 4 under walls of any height in secondary structures.

[0102] Specifically, a plurality of reserved holes are provided on the surface of the standard square steel 4 facing away from the template, and the reserved holes are distributed on the standard square steel 4 along a certain arrangement and combination. The plurality of reserved holes are not only used to position the transverse reinforcement square steel 81, but also are the installation holes of the three-stage water stop bolts 2, thereby being able to meet the transverse reinforcement size requirements of walls of any different heights.

[0103] Specifically, the extension structure 421 is provided with a plurality of mounting holes for installing screws at a certain adjustment interval. When the extension structure 421 is adjusted to a suitable position, the screws are locked into the suitable mounting holes, thereby locking the extension structure 421 to the standard square steel 41 .

[0104] In some embodiments, based on the performance of the force analysis, the distribution of the reserved holes, the floor height of common secondary structures and other considerations, the standard square steel 41 can be selected to be 2.35m. By cooperating with extension structures 421 of different specifications, the extended square steel 42 can achieve a combination of multiple lengths for some common floors, such as 2.45m, 2.55m, 2.65m, 2.85m, 4m, etc. Of course, the length combination of the extended square steel 42 is not limited to this, and extension structures 421 of different specifications can be customized as needed.

[0105] In the cast-in-place lightweight wall formwork assembly process based on the secondary structure of this embodiment, see Figure 5The internal angle plate template 3 includes a first substrate 31 and a second substrate 32 which are perpendicular to each other. The steps of installing the internal angle plate template 3 include:

[0106] S3.2.1: Use positioning tools to install the tie angle steel 13 on the top of the first base plate 31 and the second base plate 32 respectively, install the square steel 4 at the edge of the first base plate 31, install the standard square steel 41 or form the extended square steel 42 according to the drawing, align the square steel 4 with the bottom of the inner angle plate template 3, and fix and tighten the square steel 4 and the tie angle steel 13 located on the top of the first base plate 31 through the clamp 12;

[0107] S3.2.2: Use a positioning tool to install the tie angle steel 13 at the middle and bottom of the first base plate 31, respectively, so that the square steel 4 and the tie angle steel 13 are fixed and tightened by the clamp 12;

[0108] S3.2.3: Install the square steel 4 at the edge of the second base plate 32, install the standard square steel 41 or form the extended square steel 42 according to the drawing, align the square steel 4 with the bottom of the inner angle plate template 3, fix and tighten the square steel 4 and the tie angle steel 13 located at the top of the second base plate 32 through the seam clamp 12, and use the positioning tool to install the tie angle steel 13 in the middle and bottom of the second base plate 32 respectively, so that the square steel 4 and the tie angle steel 13 are fixed and tightened through the seam clamp 12;

[0109] S3.2.4: Install the square steel 4 at the right angle joint of the inner corner, install the inner corner scissors 14 at the right angle joint of the inner corner according to the drawing, and fix the square steel 4 through the inner corner scissors 14.

[0110] Specifically, during the assembly of the formwork of the secondary structure, since the formwork of the secondary structure does not require wooden squares, there is no need to use upper angle irons.

[0111] By using a simple positioning tool processed by template, it is possible to avoid re-measuring the installation position each time, thus further improving the efficiency of assembly; the internal angle scissors are used for the subsequent placement of exterior wall square tubes.

[0112] In the cast-in-place lightweight wall formwork assembly process based on the secondary structure of this embodiment, see Figure 6 , the installation steps of the plug plate template 6 are:

[0113] S3.3: Select a plugging plate of set width according to the drawing, use positioning tools to install and fix square steel 4 at the left and right edges of the plugging plate respectively, install standard square steel 41 or form extended square steel 42 according to the drawing, and complete the installation of the plugging plate template 6.

[0114] In the cast-in-place lightweight wall formwork assembly process based on the secondary structure of this embodiment, see Figure 7The assembly process also includes installing a positive angle plate template, the positive angle plate template includes a first positive angle template 91 and a second positive angle template 92, the square steel 4 includes a standard square steel 41 and an extended square steel 42, and the steps of installing the positive angle plate template include:

[0115] S3.4.1: Place the first external corner template 91 vertically on the second external corner template 92, so that the plate surface of the first external corner template 91 is flush with the end of the second external corner template 92;

[0116] S3.4.2: Install the square steel 4 on the first external angle template 91. Install the standard square steel 41 or form the extended square steel 42 according to the drawing so that the square steel 4 can cover the joint between the first external angle template 91 and the second external angle template 92. Install the tie angle steel 13 on the first external angle template 91 and fix the square steel 4 on the first external angle template 91 using the seam clamp 12.

[0117] S3.4.3: Install the square steel 4 on the second external angle template 92, install the standard square steel 41 or form the extended square steel 42 according to the drawing, so that a positive angle groove is formed between the two square steels 4, install the tie angle steel 13 on the second external angle template 92, and use the clamp 12 to fix the square steel 4 on the second external angle template 92;

[0118] S3.4.4: Install the male angle steel 16 in the male angle groove and fix the male angle steel 16 by the male angle hook 17 and the clamp 12.

[0119] By adopting the above-mentioned assembly structure, a positive angle groove is formed between the two square steels 4, which facilitates the installation of the positive angle steel 16 and solves the problem of non-standard positive and negative angles.

[0120] In the cast-in-place lightweight wall formwork assembly process based on the secondary structure of this embodiment, see Figure 7-8 The installation of the mold assembly includes the installation of the inner wall and the outer wall. The steps of installing the inner wall include:

[0121] S4.1.1: Install the internal angle plate template 3 at the internal angle, splice the standard plate template group 5 with the internal angle plate template 3, align the side of the standard plate template group 5 where the square steel 4 is not installed with the internal angle plate template 3, and fix the standard plate template group 5 through the square steel 4 and the tie angle steel 13 by the seam clamp 12;

[0122] S4.1.2: Complete the splicing of other templates so that the other templates are aligned with the bottom of the installed template;

[0123] S4.1.3: Install the height checker 15, check whether the bottom angle steel 11 is close to the ground, and use the height checker to adjust the height of the inner wall formwork after the bottom angle steel 11 is close to the ground;

[0124] S4.1.4: Install the plugging plate template 6, align the plugging plate template 6 with other templates, install the male angle steel 16 in the female angle seam formed by the two square steels 4, and fix the male angle steel 16 by the male angle hook 17 and the seam clamp 12;

[0125] S4.1.5: Install the three-stage water-stop tension screw 2 on the inner wall side in accordance with the reserved holes on the square steel 4.

[0126] It is understandable that the reserved holes on the square steel 4 need to be aligned with the reserved holes on the template.

[0127] Specifically, during the mold closing process, the internal angle plate template 3 is first installed, and then the internal angle plate template 3 is connected to the spliced ​​standard plate template group 5, and all templates need to keep the bottoms aligned; calibration is performed before installing the plugging plate template 6 to prevent the templates on both sides of the plugging plate template 6 from being misaligned.

[0128] Specifically, the three-stage water-stop tensioning screw rod 2 is used to tighten the reinforcement square steel on both sides of the wall, and to position and support the inner side of the formwork according to the design wall thickness requirements to prevent the formwork from running out of the formwork. The rotatable bolts on the inner and outer walls can be removed after the wall is formed, and the fixed bolts remain in the wall. It plays the role of plugging holes.

[0129] Preferably, the three-stage water-stop tension screw 2 is a three-stage water-stop tension screw.

[0130] In the cast-in-place lightweight wall formwork assembly process based on the secondary structure of this embodiment, see Figure 7-8 The mold assembly includes the inner wall assembly and the outer wall assembly. The installation steps of the outer wall assembly include:

[0131] S4.2.1: Install the internal angle plate template 3 at the internal angle, splice the standard plate template group 5 with the internal angle plate template 3, pass the fixing bolts of the three-stage water-stop tension screw 2 through the reserved holes on the standard plate template group 5 and the square steel 4, align the side of the standard plate template group 5 where the square steel 4 is not installed with the internal angle plate template 3, and fix the standard plate template group 5 through the square steel 4 and the tie angle steel 13 by the seam clamp 12;

[0132] S4.2.2: Complete the splicing of other templates so that the other templates are aligned with the bottom of the installed template;

[0133] S4.2.3: Install the height checker 15, check whether the bottom angle steel 11 is close to the ground, and use the height checker to adjust the height of the exterior wall formwork after the bottom angle steel 11 is close to the ground;

[0134] S4.2.4: Install the plugging plate template 6, align the plugging plate template 6 with other templates, install the male angle steel 16 in the female angle seam formed by the two square steels 4, and fix the male angle steel 16 by the male angle hook 17 and the seam clamp 12;

[0135] S4.2.5: Connect the outer wall rotatable bolts of the three-stage water-stop tension screw 2 with the fixing bolts.

[0136] Specifically, the templates are connected and fixed by square steel 4, tie angle steel 13, and clamps. When assembling the template, the screw holes of the three-stage water-stop tension screw 2 need to be passed through the reserved holes on the template and the square steel 4 to facilitate the subsequent assembly of the three-stage water-stop tension screw 2.

[0137] In the cast-in-place lightweight wall formwork assembly process based on the secondary structure of this embodiment, see Figure 7 , the steps for vertical reinforcement on the outside of the formwork include:

[0138] S5.1.1: Install the square steel 4 used for vertical reinforcement between the square steel 4 on both sides of the standard plate, and fix the square steel 4 used for vertical reinforcement to the standard plate;

[0139] S5.1.2: After all the square steel bars 4 used for vertical reinforcement are installed, use the height adjustment equipment to adjust the height again.

[0140] Specifically, by continuing to vertically reinforce the square steels 4 around the wooden board, the formwork is vertically reinforced by all the square steels 4 to increase the strength of the formwork.

[0141] In the cast-in-place lightweight wall formwork assembly process based on the secondary structure of this embodiment, see Figure 9-14 , the steps for transverse reinforcement on the outside of the formwork include:

[0142] S5.2.1: Place the reinforcing square steel 81 horizontally on the internal angle scissors 14, pass the reinforcing square steel 81 through the three-stage water-stop tension screw 2, fix and tighten the reinforcing square steel 81 through the seam clamp 12, install the buckle 21 on the three-stage water-stop tension screw 2 so that the buckle 21 is pressed on the reinforcing square steel 81, and fix the buckle 21 through a nut, and install the internal angle hook 19 on the two reinforcing square steels 81 at the internal angle seam;

[0143] S5.2.2: Place the corner 83 on the internal corner scissors 14 and fix the corner 83 by the pin and the clamp 12;

[0144] S5.2.3: Install the buckle 84 in the reinforcing square steel 81, pass the reinforcing square steel 81 through the three-stage water-stop tension screw 2, install the buckle 21 on the three-stage water-stop tension screw 2 so that the buckle 21 is pressed against the reinforcing square steel 81, and fix the buckle 21 with a nut, install the joint assembly 85 on another reinforcing square steel 81 at a right angle to the reinforcing square steel 81, and tighten the joint assembly 85 to fix the other reinforcing square steel 81;

[0145] S5.2.4: Install the joint assembly 85 on the reinforcing square steels 81 on both sides of the plugging plate template 6, install the plug 86 on the plugging plate template 6, and tighten the joint assembly 85 to fix the plug 86;

[0146] S5.2.5: Install multiple layers of transverse reinforcement structures at different levels of the mold;

[0147] S5.2.6: Inspect the reinforced formwork to check overall levelness, verticality, and height.

[0148] In some embodiments, the buckle 21 adopts a butterfly buckle, which includes a support leg extending toward the template. The support leg can be used to support the vertically supported square steel 4. Compared with the original assembly process, there is no need to add an additional buckle support structure, which further reduces the assembly process and the use of consumables.

[0149] Specifically, the position of the reinforced square steel can be limited by the internal corner scissors, and the stability can be enhanced by the internal corner hook. The corner is used to reinforce the formwork at the external corner. The reinforced square steel 81 is compressed by the press buckle 21, and the three-stage water-stop tension screw can be tightened at the same time to fix the wall panel.

[0150] In some embodiments, the multi-layer transverse reinforcement structure is preferably three or four layers. Since the cast-in-place walls of the secondary structure are non-load-bearing walls, when three or four transverse reinforcements are set, the strength requirements of the formwork are fully met, while reducing the use of materials and assembly time.

[0151] See also Figure 16-Figure 17 When the template height is 2.35m, four transverse reinforcements are set on the wall, and the spacing of the four transverse reinforcements is 300mm-550mm-600mm-600mm-300mm, the deflection at each calculated span is less than the limit value at the maximum deflection, meeting the requirements of the "Technical Regulations for Safety of Construction Templates".

[0152] See also Figure 18-19 When the template height is 2.85m, four transverse reinforcements are set on the wall, and the spacing of the four transverse reinforcements is 300mm-650mm-750mm-850mm-300mm, the deflection at each calculated span is less than the limit value at the maximum deflection, meeting the requirements of the Technical Regulations for Safety of Construction Templates.

[0153] In summary, through simulation and verification, specific dimensional requirements can be put forward for the distances of horizontal and vertical reinforcement based on the bulk density of the casting material, saving a lot of materials.

[0154] It can be understood that, as shown in the figure, the deformation of the bottom of the template is relatively large, so two reinforcing square steels 81 can be used in the transverse reinforcement structure located at the bottom of the template to further increase the strength of the bottom of the template.

[0155] In the cast-in-place lightweight wall formwork assembly process based on the secondary structure of this embodiment, see Fig.15 The height of the bottom angle steel 11 is 5 to 15 cm. The assembly process also includes:

[0156] S5.3: When there is an error in the height of the wall formed by the mold, the height adjuster 15 is adjusted by the height adjustment device so that the bottom of the template does not exceed the highest point of the bottom angle steel 11 to correct the height of the template.

[0157] Specifically, since the height under the beam or board in the room is fixed, there are strict requirements on the height of the template. In the existing assembly process, when there is a large gap between the height of the template and the beam or ceiling, the height dimension is generally met by splicing templates of appropriate sizes. In this case, the width of the template to be spliced ​​may be only a few centimeters. The installers often need to re-cut and then assemble the cut templates, which takes a lot of time. After the mold is removed, the possibility of subsequent use of these plates is very small, resulting in a waste of materials. The above-mentioned bottom angle steel 11 is used to lengthen the shielding plate of the bottom angle steel 11. In addition to completing the basic function of height calibration, when there is a large gap between the height of the template and the beam or ceiling, the height of the template is further adjusted by the height calibration equipment, thereby achieving the purpose of quickly solving the height error, improving the efficiency of assembly, and solving the problem of multiple template matching caused by height differences in indoor mold making, and meeting the high flexibility requirements of the template of the secondary structure.

[0158] In the template system of this embodiment, see Figure 5 The formwork system is assembled by the above-mentioned assembly process. The formwork system is spliced ​​by several groups of formworks enclosed on both sides of the wall. The several groups of formworks include internal angle plate formworks 3, standard plate formwork groups 5, and plugging plate formworks 6. The formwork system also includes horizontal reinforcement structures and vertical reinforcement structures for reinforcing the several groups of formworks.

[0159] It can be understood that, by using the formwork system in this embodiment, the type of square steel 4 is determined according to the drawings before assembly, the standard plate formwork is assembled into a standard plate formwork group 5 during the pre-assembly process, the standard plate formwork group 5 is directly assembled during the mold closing process, and square steel matching the wall is selected to simplify the process and steps of installing the formwork, reduce the consumables consumed in the assembly process, reduce the support materials and assembly time, thereby improving the efficiency of formwork assembly, and solving the technical problems of poor versatility, high cost and large waste of materials in the traditional building formwork process in the related technology during the cast-in-place process of secondary structures.

[0160] In the template system of this embodiment, see Figure 5 The standard plate formwork group 5 includes at least two standard formworks, and at least two standard plate formworks include a first formwork 51 and a second formwork 52 spliced ​​to each other. The joint of the first formwork 51 and the second formwork 52 is installed with an extended square steel 42, a standard square steel 41 or an extended square steel 42, and the standard square steel 41 or the extended square steel 42 is fixed to the first formwork 51 by a tie angle steel, and the extended square steel 42 or the standard square steel 41 is fixedly connected to the second formwork 52 by screws.

[0161] Specifically, the standard board formwork adopts non-standard customized board, which is customized according to the common indoor wall height, such as 1.9m, 2.3m and other common heights, to improve the versatility of the non-standard customized version. During the assembly process, there is no need to use too many templates for splicing, thereby reducing the generation of splicing seams, solving the problem of wall flatness after demolding, and improving the flatness and verticality of the wall.

[0162] In some embodiments, the first set of screws is fixed at one quarter of the square steel 4, and the remaining screws are distributed according to the length of the square steel.

[0163] Specifically, in the process of forming the standard plate formwork group 5, a certain number of standard plates are selected for assembly according to the length of the wall, the standard plate group is aligned and connected end to end according to the installation drawing, and assembled in accordance with the assembly form of "one side of the square steel 4 is the tie angle steel 13, and the other side is fixed with screws", thereby forming the standard plate formwork group 5.

[0164] It can be understood that, by using the tie angle steel 13 for fixing, the strength of the template where the tie angle steel 13 is located can be increased.

[0165] The above-mentioned assembly form not only reduces the assembly time of the mold, but also during the demolding process, there is no need to disassemble the standard plates one by one according to the traditional process. Multiple standard plates can be disassembled together as a combination at the same time. When used next time, the combination of multiple standard plates can be directly used. This not only improves the speed of assembly and demolding, but also saves the labor of transportation after demolding, improves the efficiency of assembly, and thus further improves the overall construction efficiency.

[0166] It is understandable that the primary structure is cast in the open air without a ceiling, and the secondary structure cast-in-place technology is to cast the non-load-bearing walls under the beams or slabs. Therefore, the walls and area of ​​the secondary structure are smaller than the walls of the primary structure. Whether it is customized non-standard formwork or using standard plate formwork group 5 for disassembly and assembly, the difficulty and cost are less than the use cost and installation and transportation difficulty of the formwork of the primary structure.

[0167] In the template system of this embodiment, see Figure 5 The extended square steel 42 is formed by splicing the standard square steel 41 and the extended structure 421 , and the extended structure 421 is slidably connected to the inner cavity of the standard square steel 41 .

[0168] It should be noted that, specifically, the square steel 4, the most commonly used building material in the template, is standardized and customized according to the common indoor wall height, such as common heights such as 2.35m and 2.65m, to improve the versatility of the square steel 4. During the assembly process, if the height of the wall matches the standard square steel 41, the standard square steel 41 is selected. If the square steel 4 needs to be extended, the extension structure 421 can be used. By pulling the extension structure 421, the position of the extension structure 421 can be adjusted, thereby adjusting the length of the extended square steel 42, which can reduce the use of consumables generated by splicing, simplify the assembly process, and improve the efficiency of the template assembly.

[0169] It is understandable that by customizing standard square steels of universal length and matching extension structures 421 with standard square steels 41 of various specifications, various length combinations of square steels 4 can be achieved, which can fully meet the use requirements of square steels 4 under walls of any height in secondary structures.

[0170] Specifically, a plurality of reserved holes are provided on the surface of the standard square steel 4 facing away from the template, and the reserved holes are distributed on the standard square steel 4 along a certain arrangement and combination. The plurality of reserved holes are not only used to position the transverse reinforcing square steel 81 , but also serve as installation holes for the water stop bolts 2 .

[0171] Specifically, the extension structure 421 is provided with a plurality of mounting holes for installing screws at a certain adjustment interval. When the extension structure 421 is adjusted to a suitable position, the screws are locked into the suitable mounting holes, thereby locking the extension structure 421 to the standard square steel 41 .

[0172] In some embodiments, based on the performance of the force analysis, the distribution of the reserved holes, the floor height of common secondary structures and other considerations, the standard square steel 41 can be selected to be 2.35m. By cooperating with extension structures 421 of different specifications, the extended square steel 42 can achieve some common floor height combinations of 2.45m, 2.55m, 2.65m, 2.85m, 4m and other length combinations. Of course, the length combination of the extended square steel 42 is not limited to this, and extension structures 421 of different specifications can be customized as needed.

[0173] In some embodiments, the multi-layer transverse reinforcement structure is preferably three or four layers. Since the cast-in-place walls of the secondary structure are non-load-bearing walls, when three or four transverse reinforcements are set, the strength requirements of the formwork are fully met, while reducing the use of materials and assembly time.

[0174] It can be understood that, as shown in the figure, the deformation of the bottom of the template is relatively large, so two reinforcing square steels 81 can be used in the transverse reinforcement structure located at the bottom of the template to further increase the strength of the bottom of the template.

[0175] In the template system of this embodiment, see Figure 5 The formwork system includes a bottom angle steel 11, and the bottom angle steel 11 includes a bottom plate 111 in contact with the ground and an adjustment area 112 connected to the bottom plate, and the height of the adjustment area 112 is 5 cm to 15 cm.

[0176] Specifically, since the height under the beam or board in the room is fixed, there are strict requirements on the height of the template. In the existing assembly process, when there is a large gap between the height of the template and the beam or ceiling, the height dimension is generally met by splicing templates of appropriate sizes. In this case, the width of the template to be spliced ​​may be only a few centimeters. The installers often need to re-cut and then assemble the cut templates, which takes a lot of time. After the mold is removed, the possibility of subsequent use of these plates is very small, resulting in material waste. The above-mentioned bottom angle steel 11 is used to lengthen the adjustment area 112. In addition to completing the basic function of height calibration, when there is a large gap between the height of the template and the beam or ceiling, the height of the template is further adjusted by the height calibration equipment, thereby achieving the purpose of quickly solving the height error, improving the efficiency of assembly, and solving the problem of multiple template matching caused by height differences in indoor mold making, and meeting the high flexibility requirements of the secondary structure template.
