Description

Technical Field

[0001] The present application relates to the technical field of prefabricated building formwork, and in particular to a method for processing right-angle joints of prefabricated building walls and a right-angle processing formwork. Background Art

[0002] During prefabricated building construction, the treatment of right-angled joints in walls is crucial for ensuring structural stability and exterior quality. Currently, traditional methods for treating right-angled joints have numerous practical limitations. When the first side of the wall is located outside the building facade, workers must stand on narrow scaffolding to perform formwork installation and fastening operations. This limited construction space not only makes operations difficult but also poses significant safety risks.

[0003] At the same time, the traditional formwork's fastening structure is poorly designed, making it difficult to ensure consistent spacing between the formwork panels of the internal and external corners. This can easily lead to uneven thickness of the right-angled wall after pouring, affecting structural accuracy. Furthermore, the formwork's lack of fit between the wall and the formwork often results in concrete leakage during the pouring process, which not only affects construction quality but also increases the workload for subsequent repairs. Furthermore, the installation and disassembly process of traditional formwork is cumbersome, and the fastening bolts are prone to self-rotation and jamming, resulting in low construction efficiency and low formwork reuse, which increases construction costs. Summary of the Invention

[0004] The purpose of the present invention is to solve the above-mentioned problems and provide a method for processing right-angle joints of prefabricated building walls and a right-angle processing template.

[0005] The technical solution of this application is achieved as follows:

[0006] In a first aspect, the present application provides a method for treating right-angle joints in prefabricated building walls, the method relying on a right-angle treatment template; the right-angle treatment template comprising:

[0007] External corner templates and internal corner templates, each of which comprises template plates extending in directions perpendicular to each other;

[0008] A fastening bolt and a fastening nut that can be screwed onto the fastening bolt; the fastening bolt passes through the external angle formwork and the internal angle formwork at a preset angle, so that an acute angle a is formed between the fastening bolt and the formwork plate; the internal thread of the fastening nut matches the external thread of the fastening bolt, so that the fastening nut can be sleeved and screwed onto the fastening bolt; wherein the acute angle a is 45°;

[0009] The processing method comprises:

Lay the inner side of the template module of the external corner template on the first side of the wall, insert the fastening bolts through the external corner template, align the through-holes on the internal corner template with the fastening bolts and insert the fastening bolts, and lay the inner side of the template plate of the internal corner template on the second side of the wall;

[0011] S2. Screw the fastening nut onto the fastening bolt and press the fastening nut against the internal corner formwork, so that the internal corner formwork and the external corner formwork are pressed against the wall. At this time, a casting area for casting the right-angle wall is formed between the inner side of the external corner formwork, the inner side of the internal corner formwork, and the wall;

[0012] S3, pouring concrete into the pouring area until the concrete solidifies to a predetermined strength;

[0013] S4.

After removing the fastening bolt, the external angle template can be demoulded to complete the pouring work.

[0014] The advantages or beneficial effects of the above technical solution include at least:

[0015] In a second aspect, the present application further provides a right-angle processing template. The right-angle processing template includes the right-angle processing template as described above.

[0016] The advantages or beneficial effects of the above technical solution include at least:

[0017] First, it improves construction operability, especially when the first side of the wall is outside the building facade. Workers do not need to perform complicated fastening operations on narrow construction scaffolding, which reduces construction difficulty and improves construction safety.

[0018] Secondly, the structural design of forming a 45° acute angle with the formwork plate by tightening the bolts can effectively limit the approach direction of the internal corner formwork and the external corner formwork, ensure the consistent spacing between the formwork plates, and ensure the forming accuracy of the right-angle wall.

[0019] Thirdly, through the distribution design of multiple sets of fastening bolts, the setting of sealing gaskets and the guiding role of the abutment tube, the closeness between the formwork and the wall is enhanced, the leakage of concrete during pouring is reduced, and the construction quality of the joints is guaranteed.

[0020] Fourthly, the installation and disassembly process of the template is simplified. The hexagonal slot design avoids the self-rotation of the fastening bolts.

[0040] A method for treating right-angle joints in prefabricated building walls, the method relying on a right-angle treatment template; the right-angle treatment template comprising:

[0041] The external corner template 20 and the internal corner template 30 each include template plates extending in directions perpendicular to each other. The external corner template 20 is provided with a plurality of fastening tubes 21 for receiving fastening bolts 40. The fastening tubes 21 are hollow, allowing the fastening bolts 40 to pass through the external corner template 20 and the internal corner template 30. The fastening tubes 21 also have hexagonal slots 211 corresponding to the hexagonal heads of the fastening bolts 40, allowing the hexagonal heads to fit into the hexagonal slots 211.

[0042] A fastening bolt 40 and a fastening nut 41 that can be screwed onto the fastening bolt 40; the fastening bolt 40 passes through the external corner template 20 and the internal corner template 30 at a preset angle, so that there is an acute angle a between the fastening bolt 40 and the template plate; the internal thread of the fastening nut 41 matches the external thread of the fastening bolt 40, so that the fastening nut 41 can be sleeved and screwed onto the fastening bolt 40; wherein, the angle of the acute angle a is 45°; this angle can limit the direction in which the internal corner template 30 and the external corner template 20 approach each other, ensuring that the spacing between the template plates of the two templates is consistent.

[0043] The processing method comprises:

[0044] S1. Fit the inner side of the template module of the external corner template 20 to the first side of the wall 10, pass the fastening bolt 40 through the external corner template 20, and embed the hexagonal head into the hexagonal slot 211 to prevent it from rotating. Align the through-hole on the internal corner template 30 with the fastening bolt 40 and pass the fastening bolt 40 through it, and fit the inner side of the template plate of the internal corner template 30 to the second side of the wall 10; It should be noted that the two assembled walls 10 are at right angles, such as Figure 1 As shown, the right-angled positive side is the first side surface, as shown in Figure 2 As shown, the negative side is the second side.

[0045] At this time, the internal angle template 30 can move forward and backward on the fastening bolts 40 to adapt to the thickness of the wall 10.

[0046] S2. Screw the fastening nut 41 onto the fastening bolt 40, and press the fastening nut 41 against the internal corner template 30, so that the internal corner template 30 and the external corner template 20 are pressed against the wall 10. At this time, a casting area for casting the right-angle wall 10 is formed between the inner side of the external corner template 20, the inner side of the internal corner template 30, and the wall 10; wherein, a plurality of abutment tubes 31 are installed on the outer side of the internal corner template 30; the abutment tubes 31 are hollow structures, so that the fastening bolt 40 passes through the abutment tubes 31 after passing through the internal corner template 30; the fastening nut 41 abuts against the end of the abutment tube 31;

[0047] S3, pouring concrete into the pouring area until the concrete solidifies to a predetermined strength;

[0048] S4. Unscrew the fastening nut 41 from the fastening bolt 40, and use a tool to hammer the fastening bolt 40 toward the external corner template 20 to move the fastening bolt 40 toward the external corner template 20. Then remove the fastening bolt 40. After removing the fastening bolt 40, demould the external corner template 20 to complete the pouring work.

[0049] In step S2, it should be noted that the fastening bolt 40 includes a smooth area and an external thread area; Figure 11 As shown; wherein, the external thread area is close to the end of the screw of the fastening bolt 40, and the external thread area accounts for 1 / 5 of the overall length of the fastening bolt 40; and the length of the thickened portion 311 of the abutment cylinder 31 is increased to a preset length, which is at least 3 times the length of the external thread area; it is necessary to ensure that the smooth area of ​​the fastening bolt 40 is in the casting area, and to prevent the external thread area from invading the casting area, so that the portion of the fastening bolt 40 located in the concrete can be removed. Figure 11 As can be seen from the enlarged image, the top of the external thread area is flush with the smooth area, ensuring that there will be no jamming during the template installation process.

[0050] The embodiment of the present invention also provides a right angle processing template, referring to Figure 1 and Figure 2 The template includes a positive corner template 20 and a negative corner template 30; the positive corner template 20 and the negative corner template 30 both include template plates whose extension directions are perpendicular to each other;

[0051] The ends of the formwork panels are attached to both sides of the wall 10 so that a casting area for casting the right-angle wall 10 is formed between the inner side of the external corner formwork 20, the inner side of the internal corner formwork 30 and the wall 10;

[0052] The template further includes:

[0053] Fastening bolts 40, fastening bolts 40 pass through the template at a preset angle, such as Figure 5 As shown, there is an acute angle a between the fastening bolt 40 and the template plate. The angle of the acute angle a is 45 degrees, so that the outer corner template 20 and the inner corner template 30 move along the axial direction of the fastening bolt 40. Since the thickness of the wall 10 is consistent, the acute angle a can ensure that the spacing between the template plates in the two directions is consistent, ensuring that the thickness of the right-angle wall 10 is consistent with the thickness of the straight wall 10, and as shown Figure 6As shown, the spacing between the module panels can be adaptively adjusted according to the thickness of the straight prefabricated building wall 10, so as to adapt to walls 10 of different thicknesses. In addition, it should be noted that the template is made of metal and can be reused.

[0054] A fastening nut 41, wherein the internal thread of the fastening nut 41 matches the external thread of the fastening bolt 40, so that the fastening nut 41 can be sleeved and screwed onto the fastening bolt 40;

[0055] Among them, the screw head of the fastening bolt 40 is nested in the outer side of the external corner template 20, and the fastening nut 41 abuts against the outer side of the internal corner template 30, so as to change the distance between the external corner template 20 and the internal corner template 30 by changing the position of the fastening nut 41 on the fastening bolt 40.

[0056] Based on the further improvement of the above structure, the fastening bolts 40 and the fastening nuts 41 matched therewith are assembled in at least three groups; Figure 5 As shown, one group is inserted between the angles of the formwork panels, and the other two groups are symmetrically installed on the two formwork panels. The fastening bolts 40 and fastening nuts 41 located in the middle are used to adjust the approximate spacing between the formwork panels. The fastening bolts 40 and nuts located on both sides are used to enable the formwork panels to fit with the walls 10 on both sides for secondary pre-tightening to prevent leakage during pouring. At the same time, the contact portion between the formwork panels and the wall 10 is provided with a sealing gasket 50 to further prevent leakage.

[0057] Based on the further improvement of the above structure, a number of fastening cylinders 21 for passing fastening bolts 40 are installed on the outside of the external angle template 20; the fastening cylinder 21 is a hollow structure so that the fastening bolts 40 can pass through the template through the fastening cylinder 21; and the fastening cylinder 21 is also provided with a hexagonal groove 211 corresponding to the hexagonal head of the fastening bolt 40, so that the hexagonal head can be embedded in the hexagonal groove 211. After the fastening bolt 40 passes through the template, the hexagonal head is embedded in the hexagonal groove 211, so that when the fastening nut 41 is rotated on the fastening bolt 40, the fastening bolt 40 will not rotate with it, ensuring that the fastening nut 41 can be normally rotated on the fastening bolt 40 and change its position;

[0058] Furthermore, several abutment tubes 31 are installed on the outside of the internal angle template 30; the abutment tube 31 is a hollow structure, so that the fastening bolt 40 passes through the abutment tube 31 after passing through the internal angle template 30. The abutment tube 31 has a guiding function, which enhances the contact area between the internal angle template 30 and the fastening bolt 40, so that the template is not easily deflected and stuck when moving along the axial direction of the bolt, and the fastening nut 41 abuts against the end of the abutment tube 31; the outside of the abutment tube 31 has a thickened portion 311 to increase the contact area between the nut and the abutment tube 31.

[0059] It should be noted that if Figure 11 As shown, the fastening bolt 40 includes a smooth area and an external thread area, and the fastening nut 41 can be screwed into the external thread area. When moving the internal corner template 30, it is necessary to move the internal corner template 30 in the smooth area to prevent the external thread area from invading the casting area, and the fastening cylinder 21 on the internal corner template 30 is lengthened, as shown in FIG. Figure 11 As shown, the fastening nut 41 can be tightened toward the fastening cylinder 21 in the external thread area, ensuring that the smooth area can always be located in the casting area, which facilitates the subsequent removal of the fastening bolt 40. The height of the external thread area is lower than that of the smooth area, which can facilitate the extraction of the fastening bolt 40 from the concrete.

[0060] like Figures 9 and 10 As shown, the external corner template 20 and the internal corner template 30 have reinforcing ribs to ensure that the templates are straight and not easy to bend;

[0061] When installing the template, first install the external corner template 20 on the outside of the wall 10 and make it fit the wall 10, then pass the fastening bolt 40 through the fastening cylinder 21 and the external corner template 20, so that the hexagonal head is stuck in the hexagonal slot 211, and then pass the internal corner template 30 through the fastening bolt 40, so that the internal corner template 30 fits the wall 10, and then screw the fastening nut 41 onto the fastening bolt 40 and tighten it to make the template fit tightly against the wall 10, and then you can start pouring concrete.

[0062] When the formwork is disassembled, the fastening nut 41 needs to be unscrewed, and then the internal angle formwork 30 needs to be removed. It should be noted that at this time the fastening bolt 40 is still mounted on the fastening tube 21 of the external angle formwork 20. Since the smooth area is in the concrete, the worker located in the direction of the internal angle formwork 30 can use a tool to hammer the fastening bolt 40 in the direction of the external angle formwork 20 to move it in the direction of the external angle formwork 20. Since the smooth area is in the concrete, after a certain period of knocking, the smooth area of ​​the fastening bolt 40 can be separated from the concrete, and the fastening bolt 40 can be removed. After removing the fastening bolt 40, the external angle formwork 20 can be demoulded to complete the pouring work.
