Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and specifically relates to a detachable beam formwork reinforcement device and construction method. Background Technology

[0002] In building construction, when casting concrete components such as beams on site, they are often assembled using formwork, timber, round steel pipes, and traditional steel pipe supports. Tie bolts are then used to reinforce the formwork on both sides. The selection of tie bolts depends on the cross-sectional dimensions of the component. However, this method is difficult to remove the tie bolts under the pressure of the concrete, so they can only be used once. The bolts exposed on the concrete surface need to be cut off separately using an oxy-acetylene torch, which wastes materials and labor. Moreover, due to the varying skill levels of construction workers, the bolt positions cannot be guaranteed to be uniform, leading to overloading of the beam side formwork, poor reinforcement effect, and affecting the forming quality of the component.

[0003] Chinese patent application CN217326459U discloses a socket-type beam side formwork reinforcement device, including a fixed support. The upper end of the fixed support is fixedly connected to one side of the main beam side rib. An adjusting steel pipe is provided at the side end of the fixed support. The reinforcement device also includes a sliding support. The adjusting steel pipe has several limiting holes through it in the horizontal direction, and pins are inserted into the limiting holes. The sliding support is located between the pins and the fixed support within its stroke range. This device is fixed to the main beam side rib by the fixed support and the sliding support. Due to the width limitation of the support rod, the effective area of ​​the reinforcement device is small, and a large number of reinforcement devices need to be installed sequentially to achieve a stable reinforcement effect, which increases construction costs and reduces installation efficiency. Summary of the Invention

[0004] This invention provides a detachable beam formwork reinforcement device and construction method to solve the problems of cumbersome steps, serious material waste, and high construction costs in traditional construction methods.

[0005] In view of the above problems, the technical solution proposed by the present invention is as follows:

[0006] This invention provides a detachable beam formwork reinforcement device, including a support rod, a fixed rod, a movable rod, and side ribs. The fixed rod is vertically connected to the top of the support rod, and the movable rod is slidably disposed on one side of the fixed rod and arranged parallel to the fixed rod. At least two side ribs are provided, and they are respectively movably disposed on the sides of the fixed rod and the movable rod that are close to each other. The side ribs are perpendicular to the fixed rod. The top of the support rod is in contact with the bottom of the beam formwork, and the side ribs on both sides abut against the left and right sides of the beam formwork, respectively. Each side rib is provided with a monitoring mechanism.

[0007] The monitoring mechanism includes an abutment block, a monitor, a controller, and an indicator light. Two abutment blocks and two monitors are provided, respectively located at both ends of the side rib. The abutment block is movably positioned on the side of the side rib near the beam formwork, with its outer side protruding from the side of the side rib. The monitoring end of the monitor abuts against the inner side of the abutment block. The output end of the monitor is electrically connected to the input end of the controller. The input end of the indicator light is electrically connected to the output end of the controller. The controller is equipped with a data acquisition module, a processing module, a power supply module, and a transmission module. The power supply module is electrically connected to the controller. The data acquisition module, the processing module, and the transmission module are communicatively connected to the controller.

[0008] As a preferred embodiment of the present invention, a sleeve is fixedly connected to the bottom of the movable rod, the sleeve is sleeved on the outside of the support rod, and the end of the support rod is provided with a first limiting hole array, a first limiting piece is inserted into the first limiting hole, the first limiting piece has a wedge-shaped structure, and one side of the first limiting piece abuts against the end of the sleeve.

[0009] As a preferred embodiment of the present invention, both the fixed rod and the movable rod are provided with sliding grooves, a sliding block is provided on one side of the side rib, and reinforcing ribs are provided on both sides of the sliding block. The controller is installed on the reinforcing ribs, the sliding block is in clearance fit with the sliding groove, and a second limiting hole is arrayed inside the sliding groove. A second limiting piece is inserted inside the second limiting hole. The second limiting piece has the same structure as the first limiting piece, and one side of the second limiting piece abuts against the bottom of the sliding block.

[0010] As a preferred embodiment of the present invention, the power supply module is used to provide power to the controller, the acquisition module is used to receive the signal from the monitor, the controller has preset monitoring values, the processing module is used to convert the signal from the acquisition module and compare it with the preset monitoring values ​​for calculation, the transmission module is wirelessly connected to the host computer for remote transmission of monitoring results, and at least two sets of indicator lights are provided, which are respectively located at both ends of the side rib.

[0011] As a preferred embodiment of the present invention, the side rib has a movable groove on the side near the beam template. The shape and size of the movable groove are adapted to the shape and size of the abutment block. One side of the abutment block is embedded in the movable groove. The monitor is set inside the movable groove. Threaded holes are symmetrically opened at the bottom of the movable groove. Limiting grooves are symmetrically opened on one side of the abutment block. Limiting rods are set inside the limiting grooves. The limiting rods have a "T" shape structure. The end of the limiting rod passes through the abutment block and engages with the threaded hole.

[0012] As a preferred embodiment of the present invention, the depth of the limiting groove is greater than the distance between the inner side of the abutting block and the inner wall of the movable groove.

[0013] As a preferred embodiment of the present invention, a spring is sleeved on the outer side of the limiting rod, one end of the spring is fixedly connected to the inner wall of the movable groove, and the other end of the spring abuts against the inner side of the abutting block.

[0014] On the other hand, a method for reinforcing detachable beam formwork includes the following steps:

[0015] S1, Reinforcement device assembly: Insert the sleeve at the bottom of the movable rod into the end of the support rod, and then install the corresponding number of side ribs on the fixed rod and movable rod according to the beam section height. Align the sliding block on the side rib with the sliding groove and insert it to assemble the side rib with the fixed rod and movable rod as one unit.

[0016] S2, Reinforcing device installation: After the beam formwork is laid, the assembled reinforcing device is installed at equal intervals along the extension direction of the beam formwork to the outside of the formwork. First, adjust the height position of each side rib and insert the second limiting piece into the corresponding second limiting hole to keep the side rib fixed. Then, the support rod is attached to the bottom surface of the beam formwork. Next, the side rib on one side of the fixed rod is pressed against one side of the beam formwork. Then, the movable rod is pushed inward to press the side rib on one side of the movable rod against the other side of the beam formwork. Then, the first limiting piece is inserted into the corresponding first limiting hole to limit and fix the movable rod, so that the reinforcing device is clamped and fixed on the outside of the beam formwork.

[0017] S3, the monitoring mechanism is working. The controller switches on each side rib are turned on. The squeezing force between the side rib and the side of the beam formwork is transmitted to the monitor through the abutment block. After receiving the pressure signal, the monitor transmits it to the acquisition module. The acquisition module transmits the received signal to the processing module for data conversion and compares it with the monitoring value set in advance by the controller. When the real-time data is greater than the preset monitoring value, the controller controls the indicator light to turn green. When the real-time data is less than the preset value, the indicator light turns red.

[0018] S4, Reinforcement device adjustment: The construction personnel adjust the clamping force of the reinforcement device corresponding to the red indicator light. By adjusting the insertion depth or position of the first limit piece, the distance between the side ribs on both sides is reduced to ensure that the side ribs are tightly clamped to both sides of the beam formwork until all the indicator lights on the side ribs are green.

[0019] S5, the reinforcement device is removed, concrete is poured into the formwork, and after the concrete has set, the first limiting piece is removed, the movable rod is pulled outward to separate the support rod and the fixed rod from the beam formwork, the second limiting piece on the movable rod and the fixed rod is removed, and the side ribs are separated in sequence. The various components of the reinforcement device are sorted and stored for reuse.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] (1) The device uses support rods, fixed rods and movable rods to clamp and reinforce the outer periphery of the beam formwork, and uses horizontally set side ribs to increase the clamping range of the device, reduce the number of devices required, and has a good reinforcement effect. It is also easy to install, effectively prevents the formwork from deforming and leaking grout, improves the forming quality of the components, and can be used for beam components of various sizes. The detachable structure is easy and quick to install and can be recycled, which greatly reduces the construction cost and meets the requirements of saving materials and energy.

[0022] (2) The device is equipped with a monitoring mechanism on the side ribs. The monitoring sensor senses the pressure of the side ribs in real time and reflects the clamping force between the side ribs and the beam template, avoiding unstable clamping, facilitating the installation and adjustment of the device, ensuring the stability and reliability of the template reinforcement, improving the practicality of the reinforcement device, and meeting diverse usage needs.

[0023] (3) This construction method improves the construction efficiency of the formwork reinforcement system of cast-in-place structure. The device is simple to install and easy to operate. It avoids the hole sealing work caused by the traditional method of using tie bolts, effectively saving manpower and time, reducing water seepage and sealing hazards. At the same time, it can also be used for reinforcement construction of areas such as reverse wall, suspended formwork, end structural columns, and door edge columns. It has a wide range of applications and high promotion value.

[0038] Example 1

[0039] See attached document Figure 1-6 As shown, the present invention provides a technical solution: a detachable beam formwork reinforcement device, including a support rod 101, a fixed rod 102, a movable rod 103, and side ribs 104. The fixed rod 102 is vertically connected to the top of the support rod 101, and the fixed rod 102 and the support rod 101 form an "L"-shaped integral structure. The movable rod 103 is slidably disposed on one side of the fixed rod 102, and is parallel to the fixed rod 102. The movable rod 103 can move relative to the fixed rod 102, thereby facilitating the adjustment of the distance between the two and adapting to the use of beam member formwork of different sizes. At least two side ribs 104 are provided, and are respectively movably disposed on the side of the fixed rod 102 and the movable rod 103 that are close to each other. The side ribs 104 are perpendicular to the fixed rod 102. The top of the support rod 101 is attached to the bottom of the beam formwork, and the side ribs 104 on both sides are... 4. The movable rod 103, the supporting rod 101, and the fixed rod 102 abut against the left and right sides of the beam template respectively, forming a clamp-like structure with an opening at the top. The supporting rod 101 supports the bottom template and fits against the two sides of the beam template through the side ribs 104 to clamp and reinforce the template. The side ribs 104 are movably installed on the movable rod 103 and the fixed rod 102. An appropriate number of side ribs 104 can be installed according to the actual component size, which widens the clamping range of the two sets of vertical rods on the templates on both sides. This reduces the number of reinforcement devices required for beam components of the same length compared to traditional ones, thus reducing construction costs. Each side rib 104 is equipped with a monitoring mechanism 106. The monitoring mechanism 106 is used to monitor the clamping force between each side rib 104 and the template in real time, avoiding the reduction of the clamping force due to vibration or other external forces, which would reduce the reinforcement effect of the template and ensure the reliability of the device.

[0040] The monitoring mechanism 106 includes an abutment block 1061, a monitor 1062, a controller 1063, and an indicator light 1064. Two abutment blocks 1061 and two monitors 1062 are provided, respectively located at both ends of the side rib 104. The abutment block 1061 is movably positioned on the side of the side rib 104 near the beam formwork, with its outer side protruding from the side of the side rib 104. The side rib 104 contacts the formwork surface through the protruding abutment blocks 1061 at both ends, preventing poor formwork flatness from affecting the clamping stability of the side rib 104. The monitoring end of the monitor 1062 abuts against the inner side of the abutment block 1061, and the output end of the monitor 1062... The input terminal of the controller 1063 is electrically connected. The monitor 1062 uses a pressure sensor. The clamping force generated between the template surface and the abutment block 1061 acts on the detection terminal of the pressure sensor, which generates a voltage signal. The relationship between the voltage signal and the pressure value reflects the clamping force of the side rib 104 on the template in real time. The input terminal of the indicator light 1064 is electrically connected to the output terminal of the controller 1063. The indicator light 1064 emits different colors of light under the control of the controller 1063, making it easy to intuitively identify the clamping status at the current point. The controller 1063 is equipped with a data acquisition module 10631 and a processing module 10632. The system comprises a power supply module 10633 and a transmission module 10634. The power supply module 10633 is electrically connected to the controller 1063. The acquisition module 10631, processing module 10632, and transmission module 10634 are communicatively connected to the controller 1063. The power supply module 10633 uses an external battery to provide power to the controller 1063. The acquisition module 10631 receives signals from the monitor 1062. The controller 1063 has preset monitoring values. The processing module 10632 converts the signals from the acquisition module 10631, converting the voltage signal received by the acquisition module 10631 into a pressure value. The pressure value is compared with the preset monitoring value to calculate the relationship between the pressure value data and the preset pressure detection value, thereby determining whether the clamping force of the side rib 104 is in place. The transmission module 10634 is wirelessly connected to the host computer for remote transmission of monitoring results. This facilitates the reception of monitoring result data after connecting each transmission module 10634 in the control background, realizing remote monitoring and control of the beam formwork reinforcement status of the entire construction site. There are at least two sets of indicator lights 1064, which are respectively set at both ends of the side rib 104. The two indicator lights 1064 on the same side rib 104 work synchronously, so that construction personnel in different directions can quickly observe the status of the indicator lights 1064.

[0041] The embodiments of the present invention are also implemented through the following technical solutions.

[0042] In an embodiment of the present invention, a sleeve 1031 is fixedly connected to the bottom of the movable rod 103. The sleeve 1031 is fitted onto the outside of the support rod 101, and the inner diameter of the sleeve 1031 is adapted to the outer diameter of the support rod 101, which facilitates the installation and adjustment of the movable rod 103. The end of the support rod 101 is provided with a first limiting hole 1011, and a first limiting piece 1012 is inserted into the first limiting hole 1011. The first limiting piece 1012 has a wedge-shaped structure, and one side of the first limiting piece 1012 is connected to the sleeve 103. The end of the tube 1031 abuts against the first limiting piece 1012, which is inserted into the first limiting hole 1011. The straight edge of the piece limits and abuts the end of the sleeve 1031, preventing the sleeve 1031 from being pushed backward and keeping the movable rod 103 in a clamped state. In addition, the top and side of the support rod 101 are provided with the first limiting hole 1011, and the top hole and the side hole are spaced apart, which makes the limiting effect of the first limiting hole 1011 stronger, so that the movable rod 103 can be limited and fixed to any size position.

[0043] In an embodiment of the present invention, both the fixed rod 102 and the movable rod 103 are provided with sliding grooves 105. A sliding block 1041 is provided on one side of the side rib 104, and reinforcing ribs 1042 are provided on both sides of the sliding block 1041. The controller 1063 is mounted on the reinforcing ribs 1042. The sliding block 1041 and the sliding groove 105 are in clearance fit. The fit between the sliding block 1041 and the sliding groove 105 makes it easier and faster for the side rib 104 to be installed onto the fixed rod 102 and the movable rod 103. The reinforcing rib 1042 improves the strength of the side rib 104. The sliding groove 105 has a second limiting hole 1051 arranged inside. A second limiting piece 1052 is inserted inside the second limiting hole 1051. The second limiting piece 1052 has the same structure as the first limiting piece 1012. One side of the second limiting piece 1052 abuts against the bottom of the sliding block 1041. The cooperation between the second limiting piece 1052 and the second limiting hole 1051 is used to fix the height position of the side rib 104. The operation is simple.

[0044] In an embodiment of the present invention, a movable groove 1043 is provided on the side of the side rib 104 near the beam template. The shape and size of the movable groove 1043 are adapted to the shape and size of the abutment block 1061. One side of the abutment block 1061 is embedded in the movable groove 1043. A monitor 1062 is disposed inside the movable groove 1043. When the side rib 104 contacts the template and generates pressure, the abutment block 1061 is squeezed and the force is transmitted to the detection end of the monitor 1062. At this time, the pressure of the abutment block 1061 acting on the monitor 1062 is the clamping force of the side rib 104, thereby realizing the monitoring of the clamping force. Threaded holes 1044 are symmetrically provided at the bottom of the movable groove 1043. One side of the abutment block 1061... A symmetrical limiting groove 10611 is provided, and a limiting rod 1065 is provided inside the limiting groove 10611. The limiting rod 1065 has a "T" shaped structure. The end of the limiting rod 1065 passes through the abutment block 1061 and cooperates with the threaded hole 1044. The depth of the limiting groove 10611 is greater than the distance between the inner side of the abutment block 1061 and the inner wall of the movable groove 1043. When the abutment block 1061 is squeezed, it moves into the movable groove 1043. The limiting rod 1065 prevents the abutment block 1061 from falling off the side rib 104 during the movement. At the same time, due to the depth of the limiting groove 10611, even if the abutment block 1061 moves to the innermost side, the limiting rod 1065 will not protrude from the outer surface of the abutment block 1061, thus preventing interference.

[0045] In an embodiment of the present invention, a spring 1066 is sleeved on the outer side of the limiting rod 1065. One end of the spring 1066 is fixedly connected to the inner wall of the movable groove 1043, and the other end of the spring 1066 abuts against the inner side of the abutment block 1061. The spring 1066 and the limiting rod 1065 are coaxially arranged. The spring 1066 is a compression spring, and its elastic force acts on the abutment block 1061, which facilitates the pop-out and reset of the abutment block 1061. At the same time, the monitor 1062 is provided with monitoring parameters to counteract the reaction force of the spring 1066 on the clamping force.

[0046] Example 2

[0047] See attached document Figure 7 As shown in the figure, another embodiment of the present invention provides a detachable beam formwork reinforcement construction method, which includes the following steps:

[0048] S1, assembling the reinforcement device: insert the sleeve at the bottom of the movable rod 103 into the end of the support rod 101, and then install the corresponding number of side ribs 104 on the fixed rod 102 and the movable rod 103 according to the beam section height. Align the sliding block 1041 on the side rib 104 with the sliding groove 105 and insert it, so that the side rib 104 is assembled with the fixed rod 102 and the movable rod 103 as one unit.

[0049] S2, Reinforcing device installation: After the beam formwork is laid, the assembled reinforcing device is installed at equal intervals along the extension direction of the beam formwork to the outside of the formwork. First, adjust the height position of each side rib 104 and insert the second limiting piece 1052 into the corresponding second limiting hole 1051 to keep the side rib 104 fixed. Then, the support rod 101 is attached to the bottom surface of the beam formwork. Then, the side rib 104 on one side of the fixed rod 102 is pressed against one side of the beam formwork. Then, the movable rod 103 is pushed inward to press the side rib 104 on one side of the movable rod 103 against the other side of the beam formwork. Then, the first limiting piece 1012 is inserted into the corresponding first limiting hole 1011 to limit and fix the movable rod 103, so that the reinforcing device is clamped and fixed on the outside of the beam formwork.

[0050] S3, the monitoring mechanism is activated, and the controller 1063 switch on each side rib 104 is turned on. The compressive force between the side rib 104 and the side of the beam formwork is transmitted to the monitor 1062 through the abutment block 1061. After receiving the pressure signal, the monitor 1062 transmits it to the acquisition module 10631. The acquisition module 10631 transmits the received signal to the processing module 10632 for data conversion and compares it with the monitoring value set in advance by the controller 1063. When the real-time data is greater than the preset monitoring value, the controller 1063 controls the indicator light 1064 to turn green. When the real-time data is less than the preset value, the indicator light 1064 turns red.

[0051] S4, Reinforcement device adjustment: The construction personnel adjust the clamping force of the reinforcement device corresponding to the red indicator light 1064. By adjusting the insertion depth or position of the first limiting piece 1012, the distance between the side ribs 104 on both sides is reduced to ensure that the side ribs 104 are tightly clamped to both sides of the beam formwork until all the indicator lights 1064 on the side ribs 104 are green.

[0052] S5, the reinforcement device is removed, concrete is poured into the formwork, and after the concrete has solidified, the first limiting piece 1012 is removed, the movable rod 103 is pulled outward, so that the supporting rod 101 and the fixed rod 102 are separated from the beam formwork. Then the second limiting piece 1052 on the movable rod 103 and the fixed rod 102 is removed, and the side ribs 104 are separated in sequence. The various components of the reinforcement device are sorted and stored for reuse.

[0053] The construction method provided in this embodiment forms a clamp-like grip on the beam component formwork through the installation of the reinforcement device. This has a large range of action, good reinforcement effect, and real-time monitoring of the clamping force and reinforcement status, effectively preventing accidents such as formwork leakage and bursting, and improving the forming quality of the beam component. At the same time, this construction method does not use the traditional tie bolt connection and fixation method, does not damage the formwork and internal structure of the component, effectively saves construction manpower and material costs, and improves the intelligent monitoring of the construction process.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.

A method for reinforcing detachable beam formwork, applied to the detachable beam formwork reinforcement device according to any one of claims 1 to 4, characterized in that, Includes the following steps: S1, assembling the reinforcement device: insert the sleeve at the bottom of the movable rod (103) into the end of the support rod (101), and then install the corresponding number of side ribs (104) on the fixed rod (102) and the movable rod (103) according to the beam section height. Align the sliding block (1041) on the side rib (104) with the sliding groove (105) and insert it into the groove, so that the side rib (104) is assembled with the fixed rod (102) and the movable rod (103) as a whole. S2, Reinforcing device installation: After the beam formwork is laid, the assembled reinforcing device is installed at equal intervals along the extension direction of the beam formwork to the outside of the formwork. First, adjust the height position of each side rib (104) and insert the second limiting piece (1052) into the corresponding second limiting hole (1051) to keep the side rib (104) fixed. Then, the support rod (101) is attached to the bottom surface of the beam formwork. Then, the side rib (104) on the side of the fixed rod (102) is pressed against the side of the beam formwork. Then, the movable rod (103) is pushed inward to make the side rib (104) on the side of the movable rod (103) press against the other side of the beam formwork. Then, the first limiting piece (1012) is inserted into the corresponding first limiting hole (1011) to limit and fix the movable rod (103) so that the reinforcing device is clamped and fixed on the outside of the beam formwork. S3, the monitoring mechanism is working, and the controller (1063) switch on each side rib (104) is turned on.
