Description

Technical Field

[0001] This invention relates to the field of civil engineering, and in particular to a reinforcement device and method for a protruding formwork template on an exterior wall. Background Technology

[0002] In modern architecture, many protruding moldings are incorporated into the exterior walls to enhance aesthetics. While these protrusions improve the overall appearance, they also complicate the construction process. After each set-up of the exterior wall formwork and the protrusion molding templates, workers must temporarily assemble and connect additional reinforcing templates piece by piece before finally securing them to the existing formwork and protrusion molding templates. This process is time-consuming, resulting in slow construction, long working hours, and safety risks such as falls for workers. Furthermore, this temporary assembly method cannot guarantee consistent structure and dimensions, compromising the reinforcement effectiveness of each template and ultimately leading to poor quality protrusion moldings. Summary of the Invention

[0003] The purpose of this invention is to provide a reinforcement device and method for exterior wall protrusion templates, which can reduce the operation time of protrusion template reinforcement and ensure the final protrusion forming quality.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A reinforcement device for exterior wall protrusion molding templates includes two clamping groups spaced apart vertically, a connecting group, and a fixing group. Each clamping group includes two clamping plates spaced apart front to back, two first wooden beams fixedly connected to opposite sides of the two clamping plates and spaced apart front to back, and at least two wing plates obliquely arranged opposite the clamping plates. One end of each wing plate is fixedly connected to the opposite side of the two clamping plates, and the end face of the other end of each wing plate is flush with the end face of the same end of the two clamping plates. The connecting group includes two second wooden beams spaced apart front to back. The upper sides of the two second wooden beams are fixedly connected to opposite sides of the two upper clamping plates. The lower side of the square is fixedly connected to the opposite sides of the two lower clamping plates, and the first and second wooden squares connected to the same clamping plate are arranged left and right; the fixing group includes upper and lower fixing members, the upper fixing member is fixedly connected to the upper clamping group or / and the upper side of the two second wooden squares, and the lower fixing member is fixedly connected to the lower clamping group or / and the lower side of the two second wooden squares; thus, a clamping cavity with one side opening is formed between the lower end of the upper clamping group, the upper end of the lower clamping group and the second wooden square, and an upper channel that runs through left and right and extends up and down is formed between the upper clamping group and the second wooden square, and a lower channel that runs through left and right and extends up and down is formed between the lower clamping group and the second wooden square.

[0005] The ends of the first and second timbers connected to the same plywood are flush with each other in the left-right direction, away from the plywood.

[0006] The first and second timbers connected to the same plywood are spaced apart on the left and right.

[0007] The upper fixing member is located between the first and second timbers of the upper clamping group, and one side of the upper fixing member is fixedly connected to the upper side of the two first timbers, and the other side is fixedly connected to the upper side of the two second timbers; correspondingly, the lower fixing member is located between the first and second timbers of the lower clamping group, and one side of the lower fixing member is fixedly connected to the lower side of the two first timbers, and the other side is fixedly connected to the lower side of the two second timbers.

[0008] The upper end face of the upper fixing member is flush with the upper end face of the second timber, and the lower end face of the lower fixing member is flush with the lower end face of the second timber.

[0009] The two clamping plates of the upper clamping group are flush with the lower end surfaces of the two first timbers, and the two clamping plates of the lower clamping group are flush with the upper end surfaces of the two first timbers.

[0010] The end face of the second timber facing away from the first timber is flush with the end face of the plywood on that side.

[0011] Each clamp is fixedly connected to two spaced-apart wing plates.

[0012] A method for reinforcing exterior wall protrusion molding templates involves reinforcing the exterior wall templates and protrusion molding templates using the aforementioned reinforcement device after the exterior wall templates and protrusion molding templates have been erected. The reinforcement method includes the following steps: Align the opening end of the clamping cavity of the reinforcement device with the outside of the boss-shaped template, and then move the reinforcement device toward the side facing the outer wall template until the outer end face of the boss-shaped template, which is included in the clamping cavity, contacts the second wooden block. When the outer end face of the protruding mold template in the clamping cavity abuts against the second wooden block, if the clamping plate, wing plate, and outer wall template abut against each other, and the upper and lower end faces of the protruding mold template are respectively abutting against the upper and lower end faces of the clamping cavity, they are fixedly connected to the outer wall template by passing through the upper and lower channels respectively, thereby reinforcing the outer wall protruding mold template; if the left-right dimension of the clamping plate is smaller than the left-right dimension of the protruding mold template, an auxiliary wooden block is fixedly connected to the outer wall template at the position of the corresponding wing plate, and the left-right dimension of the auxiliary wooden block is equal to the difference in left-right dimensions between the clamping plate and the protruding mold template, thereby reinforcing the protruding mold in the clamping cavity. When the outer end face of the template abuts against the second timber, the clamping plate and wing plate abut against the auxiliary timber, and then are fixedly connected to the outer wall template by passing through the upper and lower channels respectively through the upper and lower tie bolts, thereby reinforcing the outer wall protrusion template; if the vertical height of the clamping cavity is greater than the vertical height of the protrusion template, an auxiliary timber is fixedly connected to the upper end and / or lower end of the protrusion template. When the outer end face of the protrusion template in the clamping cavity abuts against the second timber, the end of the auxiliary timber away from the protrusion template abuts against the clamping cavity, and then is fixedly connected to the outer wall template by passing through the upper and lower channels respectively through the upper and lower tie bolts, thereby reinforcing the outer wall protrusion template.

[0013] Because the present invention adopts the above-described technical solution, the present invention has the following beneficial effects: 1. The reinforcement device of the present invention can be prefabricated, that is, the reinforcement device of the present invention can be manufactured in advance. After the external wall template and the external wall protrusion shaped template are set up, the reinforcement device of the present invention can be directly installed on the template. Then, the fixing device of the present invention can be connected to the external wall template and the external wall protrusion shaped template by tie bolts. Unlike traditional construction operations, it is not necessary to assemble each piece temporarily. This can greatly speed up the construction, reduce the working time, and reduce the danger to construction workers. Moreover, the prefabricated reinforcement device has a basically consistent structure and size, which can ensure the reinforcement effect of each template, that is, ensure the final protrusion forming quality. 2. The reinforcement device of the present invention adopts the above-mentioned design, so that when the template is reinforced, at least the outer side of the boss model module is restricted and fixed in the clamping cavity of the reinforcement device, which facilitates the subsequent connection of tie bolts. Moreover, the present invention uses two tie bolts to fix the parts of the reinforcement device located on the upper and lower sides of the boss model module to the outer wall template. In this way, the reinforcement device of the present invention can be firmly fixed to the outer wall template and the outer wall boss model template, and the stability of the boss model template is ensured, thereby ensuring the final boss forming quality. 3. The reinforcement device of the present invention has the aforementioned wing plates fixedly installed on the front and rear clamps. During the reinforcement construction process, the front and rear clamps and the wing plates can abut against the wooden blocks supported on the template together. This arrangement not only increases the relative contact points between the reinforcement device and the template, thus making the connection between the reinforcement device and the template more secure and further ensuring the reinforcement effect of the template and the final quality of the protrusion forming; but also, during the reinforcement construction process, the wing plates can play an anti-torsion role. That is, when the reinforcement device and the supported template are tightened by the upper and lower tie bolts, the wing plates can prevent the fixing device from twisting. Therefore, during construction, the tie bolts can be tightened faster and easier, further ensuring the reinforcement effect of the reinforcement device and the final quality of the protrusion forming. 4. The entire reinforcement device can be removed from the template by unscrewing the tie bolts, which is convenient to remove. Moreover, after removal, it can be reused for reinforcement of the same shape of the exterior wall protrusion template. That is, the reinforcement device of this invention can be reused, thereby saving costs. Attached Figure Description

Figure 4 According to Figure 3 A cross-sectional view along the AA direction. Detailed Implementation

[0015] The following description, in conjunction with the accompanying drawings and specific embodiments, illustrates the external wall protrusion molding template reinforcement device, reinforcement method, and isolation wall of the present invention.

[0016] like Figures 1 to 2As shown, this invention discloses a reinforcement device for an exterior wall protrusion molding template. The reinforcement device includes two clamping groups spaced apart at the top and bottom, a connecting group, and a fixing group. Each clamping group includes two clamping plates 1 spaced apart at the front and back, two first wooden blocks 2 fixedly connected to opposite sides of the two clamping plates 1 and spaced apart at the front and back, and at least two wing plates 3 obliquely arranged opposite the clamping plates 1. One end of each wing plate 3 is fixedly connected to the opposite side of the two clamping plates 1, and the end face of the other end of each wing plate 3 is flush with the end face of the same end of the two clamping plates 1. The connecting group includes two second wooden blocks 4 spaced apart at the front and back. The upper sides of the two second wooden blocks 4 are fixedly connected to opposite sides of the two upper clamping plates 1. The lower side of the timber 4 is fixedly connected to the opposite sides of the two lower clamping plates 1, and the first timber 2 and the second timber 4 connected to the same clamping plate 1 are arranged left and right; the fixing group includes two fixing members 5, the upper fixing member 5 is fixedly connected to the upper clamping group or / and the upper side of the two second timber 4, and the lower fixing member 5 is fixedly connected to the lower clamping group or / and the lower side of the two second timber 4; thus, a clamping cavity A1 with one side opening is formed between the lower end of the upper clamping group, the upper end of the lower clamping group and the second timber 4, and an upper channel 21 that runs through left and right and extends up and down is formed between the upper clamping group and the second timber 4, and a lower channel 22 that runs through left and right and extends up and down is formed between the lower clamping group and the second timber 4.

[0017] Because the front and rear clamping plates 1 are spaced apart, the two first wooden blocks 2 fixed on the front and rear clamping plates 1 are spaced apart front to back, and the two second wooden blocks 4 fixed on the front and rear clamping plates 1 are also spaced apart front to back. Therefore, there are gaps between the front and rear first wooden blocks 2 and between the front and rear second wooden blocks 4. Thus, the reinforcement device of the present invention forms the above-mentioned upper channel 21 and lower channel 22 that run through the left and right and extend up and down. That is, the upper channel 21 and lower channel 22 run through the entire reinforcement device in the left and right direction, and have a certain length in the up and down direction. Moreover, because the two second wooden blocks 4 are spaced apart, that is, the part of the two second wooden blocks 4 located between the upper and lower clamping groups is also spaced apart, the part of the two second wooden blocks 4 also forms a left and right through channel 23. In this way, the upper channel 21 between the upper clamping group and the second wooden block 4, the channel 23 between the part of the two second wooden blocks 4 located between the upper and lower clamping groups, and the lower channel 22 between the lower clamping group and the second wooden block 4 are connected vertically. Thus, during subsequent reinforcement construction, it is easier for the bolt 61 of the tie bolt 6 to pass through the upper channel 21 and the lower channel 22, making the construction easier and indirectly shortening the construction time.

[0018] Preferably, the end faces of the first timber 2 and the second timber 4 connected to the same clamping plate 1 that are away from the clamping plate 1 are flush in the left-right direction. That is, the rear end faces of the first timber 2 and the second timber 4 fixedly connected to the front clamping plate 1 are flush in the left-right direction, and the front end faces of the first timber 2 and the second timber 4 fixedly connected to the rear clamping plate 1 are flush in the left-right direction. In this way, the front and rear ends of the channel are flat, which makes it easier for the bolts 61 of the tie bolts 6 to pass through, thereby making the reinforcement construction easier and faster.

[0019] In this embodiment, the first timber 2 and the second timber 4, which are connected to the same clamping plate 1, are spaced apart from each other on the left and right sides. This arrangement, while maintaining the same length in the left and right directions of the clamping group, reduces the length of the first timber 2 and the second timber 4 in these directions, thus reducing the material used. If the lengths of the first timber 2 and the second timber 4 in the left and right directions remain unchanged, the length of the clamping group in these directions can be extended, thereby extending the length of the clamping cavity A1. This allows a larger portion of the boss-shaped module to be clamped within the clamping cavity A1 during reinforcement, resulting in better reinforcement and ensuring the final quality of the boss molding.

[0020] Furthermore, the upper fixing member 5 is located between the first timber 2 and the second timber 4 of the upper clamping group, and one side of the upper fixing member 5 is fixedly connected to the upper side of the two first timber 2, and the other side is fixedly connected to the upper side of the two second timber 4. Correspondingly, the lower fixing member 5 is located between the first timber 2 and the second timber 4 of the lower clamping group, and one side of the lower fixing member 5 is fixedly connected to the lower side of the two first timber 2, and the other side is fixedly connected to the lower side of the two second timber 4. This connection makes the connection between the clamping group and the second timber 4 more secure, and does not affect the passage of the tie bolt 6 through the reinforcement component. Moreover, this arrangement makes full use of the gap between the first timber 2 and the second timber 4, thereby reducing the space occupied by the upper and lower fixing members 5. In addition, this arrangement blocks the upper and lower ends of the channel, thereby preventing the tie bolt 6 from moving up or down and detaching from the fixing device of the present invention, thus making construction more convenient.

[0021] Preferably, the upper end face of the upper fixing member 5 is flush with the upper end face of the second timber 4, and the lower end face of the lower fixing member 5 is flush with the lower end face of the second timber 4, thereby avoiding too many unevennesses on the outer end face of the present invention, which would affect the movement of construction personnel.

[0022] In this embodiment, the two clamping plates 1 of the upper clamping group are flush with the lower end faces of the two first wooden blocks 2, and the two clamping plates 1 of the lower clamping group are flush with the upper end faces of the two first wooden blocks 2. This allows the reinforcing device of the present invention to be applicable not only to the reinforcement of cuboid or cubic boss-shaped templates, but also to the convenient combination with other wooden blocks to reinforce boss-shaped templates of different shapes, thus broadening the applicability of the reinforcing device of the present invention.

[0023] Preferably, the end face of the second timber 4 on the side opposite to the first timber 2 is flush with the end face of the plywood 1 on that side. Figure 1 From the perspective of the middle, the right end face of the two second wooden blocks 4 is flush with the right end face of the plywood 1.

[0024] In this embodiment, each clamping plate is fixedly connected with two spaced-apart wing plates 3. That is to say, in a clamping assembly, the front side of the front clamping plate 1 is fixedly connected with two spaced-apart wing plates 3, and the rear side of the rear clamping plate 1 is also fixedly connected with two spaced-apart wing plates 3.

[0025] The components of the reinforcement device of the present invention can be fixed by directly using screws commonly found on the construction site, which makes the materials readily available and the operation of fixing the connection simple and convenient.

[0026] Combination Figure 3 , 4 As shown, the present invention also discloses a method for reinforcing an exterior wall protrusion molding template. After the exterior wall template 7 and the exterior wall protrusion molding template 8 are erected, the aforementioned reinforcing device is used to reinforce the exterior wall protrusion molding template 8. The reinforcement method includes the following steps: Align the opening end of the clamping cavity A1 of the reinforcing device with the outside of the boss-shaped template 8 (i.e. the side of the boss-shaped template 8 away from the outer wall template 7), and then move the reinforcing device toward the side facing the outer wall template 7 until the outer end face of the boss-shaped template 8, which is included in the clamping cavity A1, comes into contact with the second wooden block 4. When the outer end face of the boss-shaped template 8 in the clamping cavity A1 abuts against the second wooden block 4, if the clamping plate 1, the wing plate 3 abut against the outer wall template 7, and the upper and lower end faces of the boss-shaped template 8 are respectively attached to the upper and lower end faces of the clamping cavity A1, then the upper and lower tie bolts 6 pass through the upper channel 21 and the lower channel 22 respectively and are fixedly connected to the outer wall template 7, thereby reinforcing the outer wall boss-shaped template 8; if the left and right dimensions of the clamping plate 1 are smaller than the left and right dimensions of the boss-shaped template 8, then auxiliary wooden blocks 92 and 93 can be fixedly connected to the outer wall template 7 at the corresponding wing plate 3 positions (in this embodiment, because each clamping plate is fixedly connected with two wing plates 3 spaced apart, it shows that there are at least two auxiliary wooden blocks spaced apart on each side, as indicated by 92 and 93 respectively), and the left and right dimensions of the auxiliary wooden blocks are equal to those of the clamping plate 1 and the boss. The dimensional difference in the left-right direction of the shaped template 8 causes the clamping plate 1, the wing plate 3, and the auxiliary wooden blocks 92 and 93 to abut against each other when the outer end face of the shaped template 8 in the clamping cavity A1 abuts against the second wooden block 4. Then, the upper and lower tie bolts 6 pass through the upper channel 21 and the lower channel 22 respectively and are fixedly connected to the outer wall template 7, thereby reinforcing the outer wall shaped template 8. If the vertical height of the clamping cavity A1 is greater than the vertical height of the shaped template 8, the auxiliary wooden block 91 can be fixedly connected to the upper end and / or the lower end of the shaped template 8. When the outer end face of the shaped template 8 in the clamping cavity A1 abuts against the second wooden block 4, the end of the auxiliary wooden block 91 away from the shaped template 8 abuts against the clamping cavity A1. Then, the upper and lower tie bolts 6 pass through the upper channel 21 and the lower channel 22 respectively and are fixedly connected to the outer wall template 7, thereby reinforcing the outer wall shaped template 8.

[0027] Before carrying out reinforcement construction, the auxiliary timbers 91, 92, and 93 are fixedly connected to the outer wall template 7 and the boss-shaped template 8. Then, the reinforcement device is moved to the side facing the outer wall template 7 until the outer end face of the boss-shaped template 8, which is included in the clamping cavity A1, contacts the second timber 4.

[0028] The support of the exterior wall template 7 and the exterior wall protrusion template 8 is a conventional technical solution. The method of fixing the reinforcement device to the exterior wall template 7 with tie bolts 6 is also a known technology. That is, wooden blocks 10 and steel pipes 101 are supported on the other side of the exterior wall template 7. Multiple wooden blocks 10 are set at intervals and attached to the other side of the exterior wall template 7. Multiple auxiliary steel pipe groups consisting of two auxiliary steel pipes 101 are set at intervals on the outside of the wooden blocks 10. Then, the tie bolts 6 are passed through the upper channel 21 / lower channel 22 of the reinforcement device of the present invention, the exterior wall templates 7 on both sides, and the two auxiliary steel pipes 101 of the auxiliary steel pipe group in sequence. Finally, the nuts 62 of the tie bolts 6 are tightened.

[0029] Because the reinforcement device of the present invention is used, and the reinforcement device of the present invention can be prefabricated, that is, the reinforcement device of the present invention can be prefabricated, so that after the outer wall template 7 and the outer wall protrusion template 8 are set up, the reinforcement device of the present invention can be directly installed on the template, and then the fixing device of the present invention can be connected to the outer wall template 7 and the outer wall protrusion template 8 by tie bolts 6. Unlike the traditional construction operation, it is not necessary to temporarily assemble each piece, which can greatly speed up the construction speed, reduce the working time, and reduce the danger to construction workers. Moreover, the prefabricated reinforcement device has a basically consistent structure and size, which can ensure the reinforcement effect of each template, that is, ensure the final protrusion forming quality.

[0030] Because the upper channel 21 and lower channel 22 of this invention extend horizontally and vertically, instead of a horizontally extending circular hole as in conventional technology where the bolt 61 of the tie bolt 6 just passes through, the conventional design requires the circular hole to be precisely aligned with the reserved hole on the outer wall template 7 for the tie bolt 6 to be inserted. This places high demands on the construction skills of workers temporarily assembling and reinforcing the template, and consequently, takes more time. The design of the upper channel 21 and lower channel 22 extending horizontally and vertically in this invention solves the problems existing in the conventional technology. Because of this design, as long as the outer side of the boss-shaped module is placed in the clamping cavity A1, a portion of the vertically extending upper channel 21 and lower channel 22 will always be aligned with the reserved hole on the outer wall template 7. This greatly reduces the installation difficulty of the reinforcement device of this invention, making the installation of the tie bolt 6 even simpler, thereby further shortening the construction time.

[0031] Because the upper channel 21 and lower channel 22 of this invention are arranged to extend horizontally and vertically, even if the vertical height of the clamping cavity A1 is greater than the vertical height of the boss-shaped template 8, the height of the inserted auxiliary wooden block 91 does not need to be specified, as long as the reinforcing device and the boss-shaped template 8 cannot move vertically relative to each other. This further reduces the difficulty of the reinforcement construction and thus further shortens the construction time.

[0032] Because the end face of the second timber 4 facing away from the first timber 2 is flush with the end face of the clamping plate 1 on the same side, the overall shape of the reinforcement device of the present invention is more compact. Moreover, when locking the tie bolt 6, the contact area between the nut 62 of the tie bolt 6 and the reinforcement device is larger. Therefore, after locking the tie bolt 6, the reinforcement device of the present invention is more tightly and firmly connected to the outer wall template 7, thereby further ensuring the final boss forming quality.

[0033] Because the reinforcing device of the present invention has the aforementioned wing plates 3 fixedly installed on the front and rear clamping plates 1, during the reinforcement construction process, the front and rear clamping plates 1 and the wing plates 3 can abut together against the auxiliary wooden blocks 92 and 93 supported on the template or template. This not only increases the relative contact points between the reinforcing device and the template, thus making the connection between the reinforcing device and the template more secure, further ensuring the reinforcement effect of the template and the final quality of the protrusion forming; but also, during the reinforcement construction process, the wing plates 3 can play an anti-torsion role. That is, when the reinforcing device and the supported template are tightened by the upper and lower tie bolts 6, the wing plates 3 can prevent the fixing device from twisting. Therefore, during construction, the tie bolts 6 can be tightened faster and easier, further ensuring the reinforcement effect of the reinforcing device and the final quality of the protrusion forming. And because each clamping plate 1 is fixed with upper and lower wing plates 3, the number of contact points between the reinforcing device of the present invention and the external wall template 7 can be further increased, further ensuring the reinforcement effect of the template and the anti-torsion effect, thus further ensuring the final quality of the protrusion forming.

[0034] When the project is nearing completion and the formwork and the reinforcement device of this invention need to be removed, the entire reinforcement can be removed from the formwork simply by unscrewing the nuts 62 of the tie bolts 6. This makes the disassembly of the reinforcement device of this invention convenient and quick, further shortening the construction time. Moreover, the removed reinforcement device can be reused for the reinforcement of the same shape of the exterior wall protrusion formwork 8. In other words, the reinforcement device of this invention is reusable, which can also save construction costs.

[0035] Those skilled in the art should understand that the above references to the relative positions of front, back, left, right, up, and down are for the purpose of better describing the relationship between the components, not for limitation, and that the relative positions will change accordingly as the viewing perspective changes.

[0036] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
