Description

Technical Field

[0001] This invention relates to the field of template joint reinforcement technology, and in particular to a template joint reinforcement device for underground ring road construction. Background Technology

[0002] Formwork joints are the gaps between formwork panels. If not reinforced, these gaps can lead to displacement and deformation of the panels, affecting the overall stability of the structure. Reinforcing formwork joints increases the rigidity and stability of the structure, ensuring the safety and reliability of the formwork system. Ineffective reinforcement of formwork joints can also cause grout leakage, resulting in waste and a decline in pouring quality. Reinforcing formwork joints effectively prevents grout leakage and ensures the quality of concrete pouring.

[0003] A search revealed Chinese patent CN113062590A, which discloses a template joint reinforcement device and its usage method, belonging to the field of building formwork construction. The device includes a first fixing plate, a second fixing plate, and a wedge-shaped component. The first fixing plate is a T-shaped plate, adapted to be installed on one side of the template joint and fitted together. One end of the first fixing plate is adapted to connect with the second fixing plate. A positioning groove is provided on the first fixing plate, and a wedge-shaped component is installed in the positioning groove. The wedge-shaped component is adapted to be fitted into the positioning groove and position the second fixing plate. This invention solves the technical problems in the prior art such as misalignment, grout leakage, holes, and exposed reinforcement caused by gaps in the template.

[0004] While the aforementioned patents have certain beneficial effects, they only consider the sealing effect of the joints between the templates, without reinforcing and fixing the template installation. When the templates shake, the gaps between them can easily widen, reducing the sealing effect. During concrete pouring, the templates are easily impacted by the concrete, and as the pouring time increases, the stability of the templates gradually decreases, making the joints between the templates prone to breakage. This reduces the overall efficiency of the device and causes concrete leakage. Furthermore, considering the expansion and contraction of concrete, the bottom of the template needs to be increased or decreased in space. Otherwise, while the templates prevent concrete leakage, the concrete may expand or contract during the hardening process due to external factors, causing cracks in the concrete. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as poor template stability leading to reduced sealing effect of template joints, and to propose a template joint reinforcement device for underground ring road construction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A formwork joint reinforcement device for underground ring road construction includes multiple formwork panels, and also includes:

[0008] A sealing assembly, comprising multiple sets, includes a slotted iron sheet installed between multiple templates. The slotted iron sheet is used to grind the sidewalls of the templates and fill the gaps between the templates. One end of the slotted iron sheet is fixedly installed with a reinforcing iron sheet to prevent cement leakage, and the reinforcing iron sheet and the slotted iron sheet form a T-shape.

[0009] A reinforcement component is used to reinforce the position of the slotted iron sheet. The reinforcement component includes multiple wooden beams fixedly installed on the side of the template away from the reinforcement iron sheet. The multiple wooden beams are respectively located on both sides of the slotted iron sheet. A main keel is connected through the wooden beams and the slotted iron sheet. Connecting components are fixedly installed at both ends of the main keel away from the slotted iron sheet.

[0010] A support assembly for stabilizing the entire device, the support assembly being located on the side of the template away from the reinforcing iron sheet.

[0011] Preferably, a fastening iron piece for fixing the reinforcing iron piece is fixedly installed at the end of the slotted iron piece away from the reinforcing iron piece, and the side wall of the fastening iron piece is provided with a threaded hole for installation.

[0012] Preferably, a pressing rod is connected through the timbers, and the pressing rod is located on the side of the timber away from the template. A snap-fit ​​iron bend is fixedly installed at one end of the pressing rod on the outer wall of the timber, and the snap-fit ​​iron bend is used to press the multiple timbers together.

[0013] Preferably, the mounting assembly is used to connect multiple timbers together, and the mounting assembly includes connectors fixedly installed at both ends of the main keel, with secondary keels fixedly installed at the bottom of the connectors, and the secondary keels being vertically installed on both sides of the timbers.

[0014] Preferably, the bottom of the template has an engineering joint, and an engineering joint plate is slidably connected to the bottom of the template to seal the engineering joint.

[0015] Preferably, a reinforcing block is fixedly installed on the side of the engineering joint board away from the engineering joint. The reinforcing block is L-shaped and located at the bottom of the lowest wooden beam, and is slidably connected to the wooden beam. A handle is fixedly installed on the side of the reinforcing block away from the engineering joint board.

[0016] Preferably, the support assembly includes a support block installed on the side of the template away from the reinforcing iron sheet. The support block is located on the side of the reinforcing block away from the template. A first support rod is fixedly connected between the top of the support block and the uppermost set of wooden beams. The first support rod is used to fix the position of the wooden beams and the pressing rod.

[0017] Preferably, a second support rod and a third support rod are fixedly installed on the side of the support block near the template, and the second support rod is located above the third support rod.

[0018] Preferably, the end of the second support rod furthest from the support block is fixedly installed with the middle wooden beam, and the end of the third support rod furthest from the support block is fixedly installed with the bottommost wooden beam.

[0019] Preferably, the joints of the template are filled with sealant, and a sealing strip is fixedly installed at the angle between the template and the interlocking iron sheet, with the sealing strip located on the side of the template away from the reinforcing iron sheet.

[0020] Compared with the prior art, the advantages of the present invention are as follows:

[0021] 1. This invention installs interlocking iron plates, reinforcing iron plates, and snap-fit ​​iron plates between templates. The interlocking iron plates polish the splicing surfaces between the templates, making the mating surfaces smoother and improving the splicing effect. At the same time, the reinforcing iron plates prevent cement from leaking from the splicing joints. The joints are sealed with sealant and sealing cotton strips, further improving the splicing effect and sealing effect of the joints. The number of interlocking iron plates can be increased according to construction requirements, making it suitable for templates of different heights and enhancing the practicality of the device.

[0022] 2. This invention uses a device that integrates pressing iron bends, main keels, and timber beams. Iron blocks are used to fix the timber beams, and the main keels are connected through the timber beams and interlocking iron plates. Secondary keels connect multiple sets of main keels, and pressing rods bring the timber beams closer together. First support rods and other components fix the position of the pressing rods, making all components a unified whole. The interaction between these components reinforces the formwork layer by layer, enhancing the sealing effect and improving the stability of the formwork. This prevents the formwork from shaking during cement pouring, which would reduce work efficiency. The entire device is simple and quick to install, requiring no bolts or other components for connection and fixation, saving a significant amount of engineering materials and improving work efficiency.

[0023] 3. This invention provides space for cement expansion by reserving an engineering joint at the bottom of the template and utilizing the movable features of the engineering joint plate and the reinforcing block. At the same time, when the cement shrinks, the engineering joint plate moves towards the cement, avoiding the concrete from being restricted by the template when the concrete shrinks during the hardening process or expands due to temperature, which would cause cracks or deformation in the concrete and result in poor concrete pouring effect, thereby reducing the practicality of the entire device.

[0024] In summary, this invention improves the sealing effect of gaps between multiple templates by installing slotted iron plates at the joints of the templates and filling the joints with sealant. The friction between the slotted iron plates and the templates makes the joints smoother, resulting in a better splicing effect. Multiple components reinforce the templates layer by layer, making them more robust and stable. The interaction between components eliminates the need for screws, nuts, and other similar components, saving engineering materials and improving work efficiency. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Reference Figure 1 , Figure 7 and Figure 8 A formwork joint reinforcement device for underground ring road construction includes a set of formwork 1, with interlocking iron plates 3 installed between the formwork 1. During installation, the interlocking iron plates 3 move up and down, causing friction and making the contact surface between the formwork 1 and the interlocking iron plates 3 smoother, removing larger impurities and preventing poor adhesion between the interlocking iron plates 3 and the formwork 1, which would result in ineffective cement blocking. A reinforcing iron plate 2 is fixedly installed at one end of the interlocking iron plate 3, forming a T-shape with the interlocking iron plate 3. The height of the formwork 1 is determined according to construction requirements, and the number of reinforcing iron plates 2 is determined based on the height of the formwork 1. This device is suitable for formwork of different heights. Plate 1 is used for gap sealing, which enhances the practicality of the device. Reinforcing iron plate 2 is used to prevent cement from entering the joint gaps of multiple templates 1, which would result in poor concrete pouring. Multiple snap-fit ​​iron plates 4 are fixedly installed on the end of the interlocking iron plate 3 away from the reinforcing iron plate 2. After determining the position of the reinforcing iron plate 2, the snap-fit ​​iron plates 4 are bent to the left and right ends to fix the position of the reinforcing iron plate 2. The operation is simple and quick, and the position of the reinforcing iron plate 2 can be fixed without the installation of other components. The side wall of the snap-fit ​​iron plate 4 has a through threaded hole 5, which is used to reinforce the device, making the device more secure and stable.

[0039] A set of templates 1 is filled with sealant 6 to prevent gaps between multiple interlocking iron plates 3, thus improving the sealing effect between templates 1. A sealing cotton strip 21 is fixedly installed at the angle between template 1 and interlocking iron plate 3. The sealing cotton strip 21 is located on the side of template 1 away from the reinforcing iron plate 2, making the splicing between a set of templates 1 tighter and improving the reinforcement effect of the splicing joint, effectively preventing concrete leakage.

[0040] Reference Figure 2 , Figure 3 , Figure 9 and Figure 10 Multiple wooden beams 7 are fixedly installed on the side of template 1 away from the reinforcing iron plate 2. When the interlocking iron plate 4 is engaged, the wooden beams 7 are fixed between template 1 and interlocking iron plate 4. The multiple wooden beams 7 are located at the left and right ends of the interlocking iron plate 3, and a main keel 10 is connected through the wooden beams 7 and the interlocking iron plate 3. A connecting piece 12 is fixedly installed at the two ends of the main keel 10 away from the wooden beams 7. A secondary keel 11 is fixedly installed at the bottom of the connecting piece 12, and the secondary keel 11 is vertically installed on both sides of the wooden beams 7. The secondary keel 11 and the connecting piece 12 are used to connect multiple sets of wooden beams 7. A pressing rod 8 is connected through the wooden beams 7. The pressing rod 8 extends from the wooden beams. The side of the 7th piece near the connector 12 is horizontally inserted into another wooden beam 7. The pressing rod 8 is located on the outer wall of the wooden beam 7, and a snap-fit ​​iron bend 9 is fixedly installed at one end of the pressing rod 8 on the outer wall of the wooden beam 7. The snap-fit ​​iron bend 9 and the pressing rod 8 are used to fix a set of fixed wooden beams 7, so that a set of wooden beams 7 are close to each other and fit together more tightly, avoiding the instability of the fixing of the wooden beams 7 to the insert iron plate 3, which would cause the insert iron plate 3 to loosen. At the same time, the pressing rod 8 squeezes the snap-fit ​​iron plate 4 to fit the wooden beam 7 more closely. The whole process does not require the installation of screws, nuts and other components, saving a lot of engineering materials, and making the reinforcement effect of the device better.

[0041] Reference Figure 3 and Figure 6 A support block 16 is installed on the side of template 1 away from the reinforcing iron plate 2. A first support rod 13 is fixedly connected between the top of the support block 16 and the uppermost set of wooden beams 7. A second support rod 14 and a third support rod 15 are fixedly installed on the side of the support block 16 close to template 1, with the second support rod 14 located above the third support rod 15. The end of the second support rod 14 away from the support block 16 is fixedly connected to the middle set of wooden beams 7, and the end of the third support rod 15 away from the support block 16 is fixedly connected to the lowermost set of wooden beams 7. The first support rod 13, the second support rod 14, and the third support rod 15 are respectively located above each set of pressing rods 8 to prevent the pressing rods 8 from rotating upward and to prevent the wooden beams 7 from loosening after the pressing rods 8 rotate upward, thus reducing the overall stability of the device.

[0042] Reference Figures 3 to 6 and Figure 11A joint 17 is provided below a set of templates 1. A joint plate 18 is slidably connected to the bottom of template 1 and is located at the joint 17. The joint plate 18 is used to prevent cement from leaking from the joint 17. A reinforcing block 19 is fixedly installed on the side of the joint plate 18 away from the reinforcing iron plate 2. The reinforcing block 19 is L-shaped and is located below the bottom set of wooden beams 7. The top of the reinforcing block 19 is slidably connected to the wooden beams 7. A handle 20 is fixedly installed on the side of the reinforcing block 19 away from the joint 17. The reinforcing block 19 is located on the side of the support block 16 close to template 1. Pulling the handle 20 will move the joint plate 18 towards the support block 16, providing space for the concrete to expand or contract freely and avoiding affecting the cement pouring effect.

[0043] In this invention, during the installation of template 1, there will be a small gap between the two templates 1, and a few centimeters of engineering joint 17 should be left at the bottom. At this time, hold the reinforcing iron plate 2 and insert the back slotting iron plate 3 and the snapping iron plate 4 into the small gap. Then move it up and down, and use the reinforcing iron plate 2 to rub the part in contact with the template 1 to remove larger impurities. The slotting iron plate 3 cleans the inside of the small gap. After cleaning, determine the number of reinforcing iron plates 2 required according to the height of template 1. After inserting them, insert the sealing cotton strip 211 into the angle between template 1 and slotting iron plate 3 to prevent concrete from seeping in during pouring. Use two wooden beams 7 to tightly clamp the slotting iron plate 3 and snapping iron plate 4 behind template 1. Then use the main keel 10 to pass through the wooden beam 7 and slotting iron plate 3, and then use the connector 12 to fix the main keel 10 and the secondary keel 11 together.

[0044] After securing the metal clip 4, bend it in a crisscross pattern and fasten it onto the timber 7. Insert the pressing rod 8 into the timber 7, passing through the timber 7 and the middle slotted metal clip 3. Then rotate the pressing rod 8 downwards, pressing the metal clip 4 down to assist in securing it. The metal clip bend 9 at the end of the pressing rod 8 is tightly inserted into the side wall of the timber 7. At this point, the pressing rod 8 and the metal clip bend 9 connect the metal clip 4, the slotted metal clip 3, and the timber 7 into a whole, eliminating the need for screws and nuts for connection and securing, thus saving a lot of engineering materials. If further reinforcement is needed, screws can be screwed into the threaded holes 5 reserved on the metal clip 4 for fixing. The devices assist each other in securing them. Fill the remaining gaps with sealant 6 to enhance the sealing effect.

[0045] The first support rod 13, the second support rod 14, and the third support rod 15 are respectively pressed against the wooden beam 7, and the angles are adjusted to press down the pressing rod 8 below. The ends are fixed by the support block 16. At this time, the wooden beam 7 clamps the interlocking iron plate 3, and the fastening iron plate 4 fastens the wooden beam 7. The pressing rod 8 connects the devices into a whole while pressing down the fastening iron plate 4. The first support rod 13, the second support rod 14, and the third support rod 15 press down the pressing rod 8 while pressing against the wooden beam 7. The reinforcement between the entire device is layered and mutually reinforcing, with a good reinforcement effect, less material used, and easy installation.

[0046] Concrete shrinks to some extent during the hardening process and expands with temperature changes. In some cases, to allow the concrete to expand or shrink freely, an engineering joint 17 can be left at the bottom of the formwork 1 to reduce cracking and deformation of the concrete surface. Before the concrete sets, the engineering joint 17 needs to be covered with an engineering joint board 18. A reinforcing block 19 is connected to the back of the engineering joint board 18. The reinforcing block 19 is located below the bottom wooden beam 7. Before pouring concrete, the reinforcing block 19 and the engineering joint board 18 can provide reinforcement and support. After the concrete has initially set, the engineering joint board 18 can be pulled back by the handle 20 to provide space for the concrete to expand or shrink freely, and it can be reused multiple times.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
