Description

Technical Field

[0001] The present application relates to the field of concrete pouring, and in particular to a formwork support structure for pouring concrete. Background Art

[0002] The concrete formwork support system is one of the indispensable technologies in modern construction. It plays a vital role in pouring concrete structures. The system is mainly responsible for maintaining the shape and size of the concrete during the hardening process until the concrete reaches sufficient strength to be self-supporting. With the development of the construction industry and the advancement of technology, the concrete formwork support technology is also constantly evolving and improving to meet the more complex and changing architectural design needs, improve construction efficiency, and ensure project quality and safety.

[0003] When pouring concrete, it is usually necessary to support the bottom formwork first, usually using a wooden formwork. During support, the installation position of the formwork should be measured repeatedly to ensure that the formwork is level, which is time-consuming and labor-intensive, and the formwork needs to be clamped to prevent concrete flow.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when pouring a concrete structure with an irregular cavity or a small-section long cavity, the space inside the cavity is small, and it is difficult to support and remove the formwork, so there is room for improvement. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides a formwork support structure for pouring concrete, aiming to solve the above problems.

[0006] A formwork support structure for pouring concrete, comprising a main support airbag, a plurality of pouring formworks and a plurality of secondary support airbags detachably connected to the outside of the main support airbag, wherein all the pouring formworks surround the main support airbag, the secondary support airbags are pressed against the pouring formworks, one end of the main support airbag is connected to a first air pump for inflating and deflation of the main support airbag, one end of each of the secondary support airbags is connected to a second air pump for inflating and deflation of the secondary support airbag, and each of the secondary support airbags is installed with an air pressure sensor for controlling the inflation and deflation of the second air pump.

[0007] By adopting the above technical solution, after the casting formwork is installed, the main supporting airbag and the auxiliary supporting airbag are inserted into the cavity, and the main supporting airbag and the auxiliary supporting airbag are inflated respectively by the first air pump and the second air pump. After the volume of the auxiliary supporting airbag expands, it supports the casting formwork and improves the formwork efficiency; in addition, the air pressure sensor can monitor the air pressure inside the auxiliary supporting airbag in real time. When the air pressure inside the auxiliary supporting airbag is lower than the air pressure required for construction, the second air pump will inflate and pressurize the auxiliary supporting airbag to ensure that the auxiliary supporting airbag can provide sufficient supporting force for the casting formwork; when the concrete structure is poured, the main supporting airbag and the auxiliary supporting airbag are deflated, and the main supporting airbag and the auxiliary supporting airbag can be pulled out of the cavity. The casting formwork does not have any additional fixing devices, which is easy to dismantle later. The whole process saves time and effort, is simple to operate, and is easy to use.

[0008] Optionally, each of the secondary supporting airbags is connected with an elastic anti-slip strip along its length, and the anti-slip strip is in close contact with the casting template.

[0009] By adopting the above technical solution, the anti-slip strip can increase the friction between the auxiliary support airbag and the casting template, thereby reducing the sliding between the auxiliary support airbag and the casting template.

[0010] Optionally, a plurality of anti-slip blocks are evenly distributed on the anti-slip strip, all of the anti-slip blocks are integrally formed with the anti-slip strip, and a plurality of slots for the anti-slip blocks to be inserted are evenly provided on the casting template.

[0011] By adopting the above technical solution, after the auxiliary support airbag is tightly attached to the casting template, part of the anti-sliding block on the auxiliary support airbag will be stuck in the slot of the casting template, thereby reducing the occurrence of slippage between the auxiliary support airbag and the casting template and improving the stability of the auxiliary support airbag supporting the casting template.

[0012] Optionally, a plurality of reinforcing strips are arranged in parallel on the outer side wall of each secondary support airbag along its length direction.

[0013] By adopting the above technical solution, on the one hand, the reinforcing strip can improve the structural strength of the secondary support airbag and reduce the occurrence of accidental rupture of the secondary support airbag; on the other hand, the reinforcing strip can reduce the area of ​​contact between the secondary support airbag and the outside world, thereby reducing the friction between the secondary support airbag and the ground when dragging the secondary support airbag for storage, reducing the wear of the secondary support airbag, and extending the service life of the secondary support airbag.

[0014] Optionally, the main support airbag is provided with a plurality of male Velcros at intervals along its length direction, each of the male Velcros is arranged around the main support airbag, and each of the secondary support airbags is connected with a plurality of female Velcros adhered to the male Velcro at intervals along its length direction.

[0015] By adopting the above technical solution, when the secondary support airbag is installed on the main support airbag, the female Velcro on the secondary support airbag is adhered to the male Velcro of the main support airbag in turn, thereby fixing the secondary support airbag on the main support airbag; in addition, construction workers can adjust the number of secondary support airbags as needed, which makes the use more flexible and improves construction efficiency.

[0016] Optionally, a reserved column is connected to a side of the casting template facing away from the auxiliary supporting airbag.

[0017] By adopting the above technical solution, after pouring is completed, the reserved column can be pushed to separate the pouring template in the cavity from the concrete structure, thereby facilitating the removal of the pouring template.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] 1. After the casting formwork is installed, the main supporting airbag and the auxiliary supporting airbag are inserted into the cavity, and the main supporting airbag and the auxiliary supporting airbag are inflated by the first air pump and the second air pump respectively. After the volume of the auxiliary supporting airbag expands, it supports the casting formwork and improves the formwork efficiency; in addition, the air pressure sensor can monitor the air pressure inside the auxiliary supporting airbag in real time. When the air pressure inside the auxiliary supporting airbag is lower than the air pressure required for construction, the second air pump will inflate and pressurize the auxiliary supporting airbag to ensure that the auxiliary supporting airbag can provide sufficient supporting force for the casting formwork; when the concrete structure is poured, the main supporting airbag and the auxiliary supporting airbag are deflated, and the main supporting airbag and the auxiliary supporting airbag can be pulled out of the cavity. The whole process saves time and labor, and is simple to operate and easy to use.

[0020] 2. After the auxiliary support airbag is in close contact with the casting template, part of the anti-sliding block on the auxiliary support airbag will be stuck in the slot of the casting template, thereby reducing the slippage between the auxiliary support airbag and the casting template and improving the stability of the auxiliary support airbag supporting the casting template.

[0021] 3. On the one hand, the reinforcement strip can improve the structural strength of the auxiliary support airbag and reduce the occurrence of accidental rupture of the auxiliary support airbag; on the other hand, the reinforcement strip can reduce the area of ​​the auxiliary support airbag in contact with the outside world, thereby reducing the friction between the auxiliary support airbag and the ground when the auxiliary support airbag is dragged for storage, reducing the wear of the auxiliary support airbag and extending the service life of the auxiliary support airbag.

[0022] 4. When installing the secondary support airbag on the main support airbag, stick the female Velcro on the secondary support airbag to the male Velcro of the main support airbag in turn, so as to fix the secondary support airbag on the main support airbag; in addition, the construction personnel can adjust the number of secondary support airbags as needed, which makes the use more flexible and improves the construction efficiency.

[0023] 5. After pouring is completed, push the reserved column to separate the pouring formwork in the cavity from the concrete structure, making it easier to remove the pouring formwork. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present application embodiment discloses a formwork support structure for pouring concrete. Figure 1 , including a main supporting airbag 2, a plurality of casting templates 1 and a plurality of auxiliary supporting airbags 3 detachably connected to the outer side of the main supporting airbag 2. Specifically, eight auxiliary supporting airbags 3 are provided.

[0032] Reference Figure 1 and Figure 2All casting templates 1 are installed at intervals around the main supporting airbag 2, and all secondary supporting airbags 3 are pressed against the casting template 1. A first air pump for inflating and deflation of the main supporting airbag 2 is installed at one end of the main supporting airbag 2, and a second air pump for inflating and deflation of the secondary supporting airbag 3 is installed at one end of each secondary supporting airbag 3, and a pressure sensor for controlling the inflation and deflation of the second air pump is installed in each secondary supporting airbag 3. After the casting formwork 1 is installed, the main supporting airbag 2 and the auxiliary supporting airbag 3 are inserted into the cavity, and the main supporting airbag 2 and the auxiliary supporting airbag 3 are inflated respectively by the first air pump and the second air pump. After the volume of the auxiliary supporting airbag 3 expands, it supports the casting formwork 1 and improves the formwork efficiency; in addition, the air pressure sensor can monitor the air pressure inside the auxiliary supporting airbag 3 in real time. When the air pressure inside the auxiliary supporting airbag 3 is lower than the air pressure required for construction, the air pressure sensor controls the second air pump to inflate through the PLC controller. The second air pump will inflate and pressurize the auxiliary supporting airbag 3, thereby ensuring that the auxiliary supporting airbag 3 can provide sufficient supporting force for the casting formwork 1; when the concrete structure is poured, the main supporting airbag 2 and the auxiliary supporting airbag 3 are deflated, and the main supporting airbag 2 and the auxiliary supporting airbag 3 can be pulled out of the cavity. The whole process saves time and labor, is simple to operate, and is easy to use.

[0033] Reference Figure 2 and Figure 3 The side of the casting template 1 away from the secondary support airbag 3 is fixedly connected with a reserved column 12. After the casting is completed, the reserved column 12 is pushed to separate the casting template 1 in the cavity from the concrete structure, so that the casting template 1 is easily taken out.

[0034] Reference Figure 2 and Figure 3 Each secondary support airbag 3 is connected with an elastic anti-slip strip 31 along its length. The anti-slip strip 31 is made of rubber material and is in close contact with the casting template 1. A number of anti-slip blocks 311 are evenly distributed on the anti-slip strip 31. All anti-slip blocks 311 are integrally formed with the anti-slip strip 31. A number of slots 11 for the anti-slip blocks 311 to be inserted into are evenly provided on the casting template 1. The anti-slip strip 31 can increase the friction between the secondary support airbag 3 and the casting template 1, thereby reducing the sliding between the secondary support airbag 3 and the casting template 1; after the secondary support airbag 3 is in close contact with the casting template 1, part of the anti-slip blocks 311 on the secondary support airbag 3 will be inserted into the slots 11 of the casting template 1, thereby reducing the occurrence of sliding between the secondary support airbag 3 and the casting template 1, and improving the stability of the secondary support airbag 3 supporting the casting template 1.

[0035] Reference Figure 2 and Figure 3On the outer side wall of each secondary support airbag 3, a plurality of elastic reinforcing strips 32 are fixedly connected in parallel along the length direction thereof, and the reinforcing strips 32 are made of rubber material. On one hand, the reinforcing strips 32 can improve the structural strength of the secondary support airbag 3 and reduce the occurrence of accidental rupture of the secondary support airbag 3; on the other hand, the reinforcing strips 32 can reduce the contact area between the secondary support airbag 3 and the outside world, thereby reducing the friction between the secondary support airbag 3 and the ground when the secondary support airbag 3 is dragged for storage, reducing the wear of the secondary support airbag 3, and extending the service life of the secondary support airbag 3.

[0036] Reference Figure 2 and Figure 3 The main support airbag 2 is fixedly connected with a plurality of male Velcro 21 in strip shape at intervals along its length direction, and each male Velcro 21 is arranged around the main support airbag 2. Each secondary support airbag 3 is fixedly connected with a plurality of female Velcro 33 adhered to the male Velcro 21 at intervals along its length direction. When the secondary support airbag 3 is installed on the main support airbag 2, each female Velcro 33 on the secondary support airbag 3 is adhered to the male Velcro 21 of the main support airbag 2 in sequence, so as to fix the secondary support airbag 3 on the main support airbag 2; in addition, the construction personnel can adjust the number of secondary support airbags 3 according to the needs, which is more flexible to use and improves the construction efficiency.

[0037] The implementation principle of a formwork support structure for pouring concrete in an embodiment of the present application is as follows: after the pouring formwork 1 is installed, the main support airbag 2 and the auxiliary support airbag 3 are inserted into the cavity, and the main support airbag 2 and the auxiliary support airbag 3 are inflated respectively by the first air pump and the second air pump. After the volume of the auxiliary support airbag 3 expands, it supports the pouring formwork 1, thereby improving the formwork efficiency; in addition, the air pressure sensor can monitor the air pressure inside the auxiliary support airbag 3 in real time. When the air pressure inside the auxiliary support airbag 3 is lower than the air pressure required for construction, the air pressure sensor controls the second air pump to inflate through the PLC controller, and the second air pump will inflate and pressurize the auxiliary support airbag 3, thereby ensuring that the auxiliary support airbag 3 can provide sufficient supporting force for the pouring formwork 1; when the concrete structure is poured, the main support airbag 2 and the auxiliary support airbag 3 are deflated, and the main support airbag 2 and the auxiliary support airbag 3 are pulled out of the cavity. The whole process saves time and effort, is simple to operate, and is easy to use.
