Technical Field

[0001] The present application relates to the technical field of construction engineering, and in particular to a detachable formwork structure for a deformation joint protective wall. Background Art

[0002] The deformation joint protection wall is a double wall close together. The deformation joint is a general term for expansion joints, settlement joints and seismic joints. The wall often deforms under the influence of external factors, resulting in cracks or even damage. The deformation joint is a structural joint reserved for this situation. The deformation joint is usually narrow, generally 10-20cm.

[0003] In the process of constructing deformation joint protective wall, formwork is usually used to assist the construction. The formwork is an integrated setting. During construction, the operator fixes the formwork in a suitable position, and then pours concrete in the formwork. After solidification, the construction is completed.

[0004] The above-mentioned existing technical solutions have the following defects: the deformation joint protection wall formwork is difficult to remove after the wall is poured and the formwork cannot be used in a cyclical manner, resulting in a large amount of material waste, so there is still room for improvement. Utility Model Content

[0005] In order to improve the convenience of construction and reduce resource waste, the present application provides a detachable formwork structure for a deformation joint protective wall.

[0006] The present application provides a deformation joint protection type wall detachable formwork structure adopts the following technical solution:

[0007] A detachable formwork structure for a deformation joint protective wall includes a prefabricated formwork, a reinforcement piece and a locking assembly, the prefabricated formwork includes an outer formwork and an inner formwork, the outer formwork and the inner formwork are spliced ​​and fixed by the locking assembly, the reinforcement piece is fixed to the outer side walls of the outer formwork and the inner formwork, the locking assembly includes a tension screw, a dovetail clamp, a locking nut, a barrier sleeve and a fastening bolt, the ends of the tension screws pass through and are threadedly connected to the fastening bolts, the dovetail clamp, the outer formwork, the inner formwork, the barrier sleeve and the locking nut in sequence, and a lifting lug is fixed to the reinforcement piece.

[0008] By adopting the above technical solution, during construction, the operator fixes the reinforcements on the outer walls of the outer formwork and the inner formwork, then places the inner formwork toward one side of the deformation joint wall, then ties the steel bars, then splices the outer formwork and the inner formwork together, then passes the tension screw through one side wall of the reinforcement, the outer formwork, the inner formwork and the other side wall of the reinforcement in sequence, and threads the barrier sleeve and the locking nut to the end of the tension screw close to the inner formwork, then positions the assembled prefabricated formwork at the designated position, then screws the end of the tension screw close to the deformation joint wall into the deformation joint wall, then installs the dovetail clip and the fastening bolt at the other end of the tension screw, and after the entire formwork system is tied and fixed The concrete can be poured, and the reinforcement piece reinforces the precast formwork, improves the stability of the precast formwork, fixes the precast formwork by the tension screw rod, and then pours concrete in the precast formwork. After solidification, the deformation joint protective wall is completed. When disassembling the precast formwork, the operator first removes the fastening bolts and dovetail clips, and then removes the tension screw rods from the precast formwork, and then lifts and transfers the precast formwork through the lifting lugs, thereby realizing the transportation and turnover of the precast formwork, solving the problem that the deformation joint protective wall formwork is difficult to remove after the wall is poured and the formwork cannot be circulated, resulting in a large amount of material waste, improving the convenience of construction and saving resources.

[0009] Preferably, a sleeve is passed through the prefabricated template, and the tension screw is inserted into the sleeve.

[0010] By adopting the above technical scheme, the supporting effect of the surrounding concrete can be strengthened by setting the sleeve, and the shear strength can be enhanced, thereby ensuring the fixing effect of the tension screw. After pouring the concrete, the concrete layer and the tension screw are isolated by the sleeve, so that the tension screw is not fixed together with the concrete, which makes it easier for the operator to remove the tension screw when disassembling the formwork.

[0011] Preferably, it further comprises a reinforcing diagonal brace rod, one end of which is connected to the outer side wall of the reinforcing member, and the other end of which is supported on the ground.

[0012] By adopting the above technical solution and setting diagonal braces, a supporting effect is achieved on the prefabricated formwork, thereby enhancing the overall stability of the formwork and achieving a reinforcement effect.

[0013] Preferably, a plurality of lifting lugs are provided, and the plurality of lifting lugs are spaced apart along the top of the reinforcement member.

[0014] By adopting the above technical solution, a plurality of lifting lugs are arranged at intervals along the top of the reinforcement member, so that the operator can choose to use any lifting lug to lift the prefabricated formwork according to the stress conditions of the prefabricated formwork, thereby improving the convenience of turnover.

[0018] By adopting the above technical solution, the reinforced diagonal brace and the reinforcement piece are fixed by bolts, which is simple to operate, easy to implement, and convenient to disassemble and assemble.

[0019] Preferably, the reinforcing diagonal brace rods may be steel pipes, steel sections or aluminum mold diagonal braces.

[0020] By adopting the above technical solution, the reinforced diagonal bracing rods can be made of materials with certain support properties such as steel pipes, steel sections or aluminum mold diagonal braces, thereby improving the stability and safety of the construction.

[0021] Preferably, a plurality of the tension screws are installed on the prefabricated template, and a gap between two adjacent tension screws is 500-600 mm.

[0022] By adopting the above technical solution, the gap between two adjacent tension screws is reasonably set to 500-600mm, which can better ensure the auxiliary construction effect of the precast formwork and save materials. If the gap between two adjacent tension screws is less than 500mm, the amount of tension screws used is relatively large, which increases the resource burden. If the gap between two adjacent tension screws is greater than 600mm, the precast formwork is insufficiently fixed by the tension screws, which can easily cause local stress rupture of the precast formwork when pouring concrete in the precast formwork.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: during construction, the operator fixes reinforcements on the outer walls of the outer formwork and the inner formwork, then places the inner formwork toward one side of the expansion joint wall, then ties the steel bars, and then splices the outer formwork and the inner formwork together, and then successively passes the tension screw through one side wall of the reinforcement, the outer formwork, the inner formwork and the other side wall of the reinforcement, and threadingly connects the barrier sleeve and the locking nut to the end of the tension screw close to the inner formwork, and then positions the assembled prefabricated formwork at the designated position, and then screws the end of the tension screw close to the expansion joint wall into the expansion joint wall, and then installs the dovetail clip and the fastening bolt at the other end of the tension screw to tie and fix the entire After the formwork system is established, concrete can be poured. The reinforcement parts reinforce the precast formwork and improve the stability of the precast formwork. The precast formwork is fixed by the tension screws, and then concrete is poured in the precast formwork. After solidification, the deformation joint protective wall is completed. When disassembling the precast formwork, the operator first removes the fastening bolts and dovetail clips, then removes the tension screws from the precast formwork, and then lifts and transfers the precast formwork through the lifting lugs, thereby realizing the transportation and turnover of the precast formwork, solving the problem that the deformation joint protective wall formwork is difficult to remove after the wall is poured and the formwork cannot be circulated, resulting in a large amount of material waste, improving the convenience of construction and saving resources.

[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] The present application embodiment discloses a deformation joint protection type wall detachable formwork structure. Figure 1 and Figure 2A deformation joint protection type wall detachable formwork structure includes a prefabricated formwork 1, a locking assembly 2, a reinforcement member 3 and a reinforcement diagonal brace 4. The prefabricated formwork 1 can be an aluminum formwork, a steel formwork or a brass formwork, preferably an aluminum formwork. The aluminum formwork has the advantages of high strength, good corrosion resistance, and long service life. It is not easy to be damaged despite frequent movement and installation during construction. The prefabricated formwork 1 includes an outer formwork 101 and an inner formwork 102. The outer formwork 101 and the inner formwork 102 are of the same shape and size, and the thickness of the outer formwork 101 and the inner formwork 102 is usually 4mm. The reinforcement member 3 is fixed on the outer side walls of the outer formwork 101 and the inner formwork 102. The outer formwork 101 and the inner formwork 102 are spliced ​​together facing each other, and the reinforcement member 3 completely covers the outer side walls of the outer formwork 101 and the inner formwork 102. The thickness of the reinforcement member 3 is greater than the thickness of the outer formwork 101 or the inner formwork 102. The reinforcement member 3 reinforces the prefabricated formwork 1 and improves the stability of the prefabricated formwork 1. The locking assembly 2 penetrates the prefabricated template 1 to fix the prefabricated template 1, and a lifting lug 5 is fixed on the reinforcement member 3. A plurality of lifting lugs 5 are provided, and the plurality of lifting lugs 5 are spaced apart along the top of the reinforcement member 3. One end of the reinforcement diagonal brace 4 is connected to the outer side wall of the reinforcement member 3, and the other end of the reinforcement diagonal brace 4 is supported on the ground, and the angle between the reinforcement diagonal brace 4 and the reinforcement member 3 is 45-60 degrees.

[0030] During construction, the operator reinforces the outer formwork 101 and the inner formwork 102 through the reinforcement member 3, splices them together, and then positions them at the designated position, and then fixes the outer formwork 101 and the inner formwork 102 through the locking assembly 2, and then fixes the reinforcement diagonal brace rod 4 on the outside of the reinforcement member 3, so that the reinforcement diagonal brace rod 4 obliquely supports the precast formwork 1. After the installation is completed, concrete can be poured in the precast formwork 1, and the deformation joint protective wall is completed after the concrete solidifies and forms. When pouring concrete into the precast formwork 1, the precast formwork 1 will be subjected to a large lateral pressure. If there is no oblique support, the precast formwork 1 is prone to overturning and sideways, affecting the pouring quality and construction safety. By installing the reinforcement diagonal brace rod 4, the position of the precast formwork 1 can be effectively fixed, the lateral pressure can be resisted, and the stability and safety of the precast formwork 1 can be ensured. The stable precast formwork 1 can ensure the flatness and verticality of the concrete pouring, improve the pouring quality, and reduce the later repair work. Reasonable arrangement of the reinforcement diagonal bracing rods 4 can keep the prefabricated formwork 1 in a good state under stress conditions, thereby ensuring the concrete forming effect.

[0031] The material of the reinforcing diagonal brace 4 should have sufficient strength and durability to withstand the weight of the prefabricated formwork 1 and the lateral pressure during the pouring of concrete. Steel pipes, steel sections and other materials can be used, and the reinforcing diagonal brace 4 can be fixed together with the reinforcing member 3 by welding, bolting and the like. Bolt connection is preferred to facilitate subsequent disassembly and assembly. The reinforcing member 3 can be a reinforcing square tube or a reinforcing keel, and the specification of the reinforcing square tube is 60*40*2.5mm. When disassembling the prefabricated formwork 1, the operator separates the reinforcing diagonal brace 4 from the reinforcing member 3, then removes the locking assembly 2 from the prefabricated formwork 1, and then hoists and transfers the prefabricated formwork 1 through the lifting lug 5, thereby realizing the handling and turnover of the prefabricated formwork 1.

[0032] Furthermore, a sleeve 6 is fixed on the prefabricated template 1, and the sleeve 6 is located between the outer template 101 and the inner template 102. There are a plurality of sleeves 6, and the plurality of sleeves 6 horizontally penetrate the outer template 101 and the inner template 102, and the plurality of sleeves 6 are distributed in an array. Figure 3 , the locking assembly 2 is correspondingly provided with several, specifically, the locking assembly 2 includes a tension screw 21, a dovetail clamp 22, a locking nut 23, a blocking sleeve 24 and a fastening bolt 25. When the outer template 101 and the inner template 102 are spliced, the operator fixes the sleeve 6 between the outer template 101 and the inner template 102. After the outer template 101 and the inner template 102 are reinforced by the reinforcement member 3, the operator then sequentially passes the end of the tension screw 21 through the side wall of the reinforcement member 3 near the outer template 101, the outer template 101, the sleeve 6, the inner template 102 and the side wall of the reinforcement member 3 near the inner template 102 Wall, and the blocking sleeve 24 and the locking nut 23 are threadedly connected at the end of the tension screw 21 close to the inner template 102, the blocking sleeve 24 is located between the locking nut 23 and the inner template 102, the inner template 102 is placed toward the deformation joint wall 7, the end of the tension screw 21 close to the deformation joint wall 7 is screwed into the deformation joint wall 7, and then the dovetail clip 22 and the fastening bolt 25 are threadedly connected at the end of the tension screw 21 close to the outer template 101, the dovetail clip 22 is located between the outer template 101 and the fastening bolt, and the entire template system can be tied and fixed by tightening the fastening bolt 25.

[0033] Several tension screws 21 are installed on each prefabricated formwork 1, and the gap between two adjacent tension screws 21 is 500-600mm. The fixing effect of the tension screw 21 mainly comes from the friction between the surrounding concrete, but the shear strength of the concrete is relatively poor, and the tension screw 21 is prone to sliding deformation when subjected to shear force. The provision of the sleeve 6 can strengthen the supporting effect of the surrounding concrete and enhance the shear strength, thereby ensuring the fixing effect of the tension screw 21. Concrete contains a large amount of water, and the tension screw 21 is made of iron, which is easily corroded by water and rusted. By providing the sleeve 6, the tension screw 21 can be effectively prevented from being corroded by water and its service life can be extended. After the sleeve 6 is provided, the tension screw 21 can be separated from the concrete, which is convenient for construction personnel to pour concrete in the middle of the steel bars, enhance the compactness and stability of the concrete, and also facilitate subsequent operators to remove the tension screw 21.

[0034] The implementation principle of a deformation joint protection type wall detachable formwork structure in the embodiment of the present application is:

[0035] During construction, the operator fixes the reinforcement member 3 on the outer side walls of the outer formwork 101 and the inner formwork 102, and then places the inner formwork 102 toward the side of the deformation joint wall 7. Then, the steel bars are tied, and then the outer formwork 101 and the inner formwork 102 are spliced ​​together, and the sleeve 6 is fixed between the outer formwork 101 and the inner formwork 102, and then the end of the tension screw 21 is successively passed through the side wall of the reinforcement member 3 near the outer formwork 101, the outer formwork 101, the sleeve 6, the inner formwork 102, and the side wall of the reinforcement member 3 near the inner formwork 102, and the blocking sleeve 24 and the locking nut 23 are threadedly connected to the end of the tension screw 21 near the inner formwork 102. Then, the assembled prefabricated formwork 1 is positioned at a designated position, and then the end of the tension screw 21 close to the deformation joint wall 7 is screwed into the deformation joint wall 7, and then the dovetail clamp 22 and the fastening bolt 25 are threadedly connected to the end of the tension screw 21 close to the outer formwork 101, and the fastening bolt 25 is tightened to tighten and fix the entire formwork system. Then, the reinforcement diagonal brace 4 is fixed on the outside of the reinforcement member 3, so that the reinforcement diagonal brace 4 supports the prefabricated formwork 1 obliquely.

[0036] After installation, concrete can be poured into the prefabricated formwork 1, and the protective wall of the deformation joint is completed after the concrete solidifies and takes shape. When disassembling the prefabricated formwork 1, the operator separates the reinforcing diagonal brace 4 from the reinforcing member 3, and then removes the fastening bolts 25 and the dovetail clip 22 from the tension screw 21, and then removes the tension screw 21 from the prefabricated formwork 1. The barrier sleeve 24 will fall between the deformation joint wall 7 and the protective wall, and the outer formwork 101 and the inner formwork 102 can be hoisted and transferred by the lifting lug 5, thereby realizing the transportation and turnover of the prefabricated formwork 1. The problem that the deformation joint protective wall formwork is difficult to remove after the wall is poured and the formwork cannot be used in a turnover manner, which causes a large amount of material waste, improves the convenience of construction and saves resources.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
