Description

Technical Field

[0001] This invention relates to the field of building casting formwork, specifically to a building casting formwork connector and a formwork laying construction method. Background Technology

[0002] Concrete pouring is the construction process of pouring prepared concrete into a formwork, leveling it, and compacting it. The pouring process requires continuity and uniformity, and must prevent segregation of the concrete. It is an essential building forming process for existing concrete structures.

[0003] The construction procedures for cast-in-place structures are determined during the design phase to meet requirements such as aesthetic appearance and uniform stress distribution. These procedures impose certain requirements on the shape and flatness of the cast-in-place surface. For example, in bridge support structures, besides smooth lines for aesthetic appeal, the overall shape of the cast-in-place structure must be uniform and standardized to ensure even stress distribution across each unit area, thus improving service life and support stability. Deviations in shape can lead to uneven thickness or angles in the cast-in-place structure, resulting in uneven stress distribution and uneven support forces on the top support structure. The main impact is on the uneven pressure distribution between the structure and the foundation, which can have a fatal impact on the overall structural stability and service life of the cast-in-place structure. In view of these problems, a formwork connector for building casting and a formwork laying construction method are proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a formwork connector for building casting and a formwork laying construction method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a building casting formwork connector, comprising a formwork for casting and shaping, a connector body for connecting the joint positions of the formwork, and a joint inspector for assisting in adjusting the connector body. The formwork comprises a formwork component one and a formwork component two, and fixing holes are evenly provided at the joint positions of the formwork component one and the formwork component two.

[0006] The connector body includes a connecting screw, and fixing nuts are fitted on both sides of the connecting screw. The fixing nuts are clamped inward and fixed on the outside of the joint position of template part one and template part two. An adjusting member is sleeved on the outside of the connecting screw. A wedge is tightly fitted between the outside of the adjusting member and the gap between template part one and template part two. The wedge can move inward or outward.

[0007] Preferably, the seam inspector includes a fixed frame, a magnetic block is fixedly mounted on the inner center of the fixed frame, a main guide wheel is rotatably mounted on the outermost side of the fixed frame, a displacement sensor is fixedly mounted on the left side of the fixed frame, and a follower is mounted on the displacement end of the displacement sensor.

[0008] Preferably, the template further includes a template component suitable for curved surfaces.

[0009] Preferably, an adjusting nut is tightly fitted to the outermost side of the wedge, and the adjusting nut is screwed onto the outermost end of the connecting screw.

[0010] Preferably, a connecting rod is fixedly assembled between the displacement sensor and the fixed frame, and a driven wheel is rotatably assembled on the outer side of the driven member.

[0011] Preferably, the passive running direction of the displacement sensor is perpendicular to the running direction of the main drive wheel.

[0012] Preferably, a controller is mounted on the back of the fixing frame, the controller is electrically connected to the displacement sensor, and a drive motor is mounted inside the main guide wheel, the drive motor being electrically connected to the controller.

[0013] A construction method for laying formwork in building casting includes the following steps:

[0014] Step A: Prepare the template. Based on the shape of the building to be cast, use BIM technology to accurately determine the specific shape, curvature, size, and splicing joint position of the template. After the design is completed, make the corresponding template according to the data dimensions. The manufacturing process mainly includes cutting and welding. After cutting the plate, weld the edge joint fixing strips. In addition, according to the template area and the volume and density of the internal cast body, add reinforcing ribs to support the internal pressure during casting.

[0015] Step B: Construction preparation. After excavating the foundation pit, the pile foundation and ground foundation are poured, and the internal steel reinforcement of the poured body is constructed.

[0016] Step C: Assemble the template. Determine the calibration point position for pouring the outer formwork based on the location of the pile foundation and the steel reinforcement frame. Position and install the template according to the calibration point position and the template with calibration standard. Then assemble the template to both sides according to the reference position. During assembly, after aligning the joint positions, insert the connecting bolt into the inside of the fixing hole. Then screw the fixing nut on the innermost side of the connecting bolt for initial fixation and maintain the initial positioning between the two adjacent template pieces. Then, attach the adjusting piece to the outside of the fixing nut. Then, insert the wedge between the outer plate of the template and the connecting bolt. Finally, screw the adjusting nut into the outermost side of the wedge.

[0017] Step D: Adjust the flatness of the inner plate of the template. Use a combination of steel cable and electric cable to connect the joint inspector to the template via mechanical and electrical connections. Then place the joint inspector at the bottom of the inner wall of the template and start the equipment. The main drive wheel is driven by the drive motor and moves. The magnetic block generates magnetic force and adheres to the inner wall of the template. As the main drive wheel moves upward, the entire equipment moves upward along the inner wall of the template as a reference. During the movement, the unevenness of the inner wall of the newly installed template will cause the driven part to move relative to the fixed frame. The displacement sensor records the position in real time. Finally, according to the deviation of the inner wall of the joint, rotate the adjusting nut to move the wedge inward or outward to adjust the staggered position of the joint. After the adjustment is completed, tighten the fixing nut to achieve positioning.

[0018] Step E: After the template is fixed, pour the inner cavity of the template.

[0019] Preferably, in step A, the density of the reinforcing ribs at the bottom of the template is greater than the density of the reinforcing ribs at the top of the template.

[0020] Preferably, in step C, before adjusting the inner and outer positions of two adjacent templates, it is necessary to adjust the bottom positions of the two adjacent templates, and use the bottom anchor rods to adjust the horizontal position and level the bottom.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention develops a connector body that can adjust the flatness of the joint surface between two adjacent templates and a joint inspector for automatically checking the gap between the joint surfaces. In use, the data obtained by the joint inspector can be used to directly determine the position of the wedge by adjusting the position of the adjusting nut, thereby adjusting the position of the gap between the planes of two adjacent mold plates, ensuring that the shape of the cast building is more standard, and minimizing the shape error between the final cast body and the design. Therefore, in actual use, the cast body can work more evenly according to the stress effect designed, ensuring the overall standard forming effect of the cast body and improving the uniformity of stress on the cast body.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-5 The present invention provides a technical solution: a building casting formwork connector, including a formwork 1 for casting and shaping, a connector body 2 for connecting the joint position of the formwork 1, and a joint inspector 3 for assisting in the adjustment of the connector body 2. The formwork 1 includes a formwork component 11 and a formwork component 22, and fixing holes are evenly provided at the joint position of the formwork component 11 and the formwork component 22.

[0030] The connector body 2 includes a connecting screw 21. Fixing nuts 22 are fitted on both sides of the connecting screw 21. The fixing nuts 22 are clamped inward and fixed on the outside of the joint between template part 11 and template part 22. An adjusting member 23 is sleeved on the outside of the connecting screw 21. A wedge block 24 is tightly fitted on the outside of the adjusting member 23 at the gap between template part 11 and template part 22. The wedge block 24 can move inward or outward.

[0031] This invention develops a connector body 2 capable of adjusting the flatness of the joint surface between two adjacent templates, and a joint inspector 3 for automatically checking the gap between the joint surfaces. In use, the data obtained by the joint inspector 3 can be used to directly adjust the position of the adjusting nut 25 to determine the position of the wedge 24, thereby adjusting the position of the gap between the planes of the two adjacent mold plates. This ensures that the shape of the cast building is more standard and minimizes the shape error between the final cast body and the design. Therefore, in actual use, the cast body can work more evenly according to the designed stress effect, ensuring the overall standard of the cast body and improving the uniformity of stress on the cast body.

[0032] Specifically, the seam inspector 3 includes a fixed frame 31, with a magnetic block 32 fixedly mounted on the inner center of the fixed frame 31, a main guide wheel 33 rotatably mounted on the outermost side of the fixed frame 31, a displacement sensor 37 fixedly mounted on the left side of the fixed frame 31, and a follower 35 mounted on the displacement end of the displacement sensor 37. The magnetic block 32 is an electromagnet structure that can generate magnetic force after being energized, assisting the fixed frame 31 in adsorbing onto the inner wall of the template 1. While ensuring that it does not affect walking, it supports the overall device to adsorb and walk on the inner wall of the template 1. Depending on the material of the template 1, when magnetic adsorption cannot adsorb, a negative pressure adsorption device can be selected instead. This technology is most commonly used inside glass cleaning robots, which can use the negative pressure generated by airflow to adsorb the device onto the outside of the plane. The adsorption and walking methods of the seam inspector 3 are not limited to the above two.

[0033] Specifically, template 1 also includes template element 13 suitable for curved surface shapes.

[0034] Specifically, the outermost side of the wedge 24 is tightly fitted with an adjusting nut 25, which is screwed onto the outermost end of the connecting screw 21, as shown in Figure 5. The acute angle of the inclined surface of the wedge 24 is preferably 45 degrees, but it can also be 30 degrees, and its cross-section is a right triangle or a right trapezoid. When moving left or right, given the pitch, the number of rotations can be determined, and the corresponding distance can be moved. Based on this distance and trigonometric functions, the change in distance between the two templates after moving a fixed number of times can be calculated. That is, rotating the adjusting nut 25 a fixed number of times can adjust the distance between the template planes at the corresponding distance. This value can be positive or negative.

[0035] Specifically, a connecting rod 34 is fixedly mounted between the displacement sensor 37 and the fixed frame 31, and a driven wheel 36 is rotatably mounted on the outside of the driven member 35. Through the above measurement method, in conjunction with the movement of the fixed frame 31, the inner wall edge of the initial template 1 is used as the initial value. The driven member 35, which moves against the inner wall of another template 1, will drive the displacement detection end of the displacement sensor 37 to change displacement. At each measurement position, this displacement change will be compared with the base position, and the positive and negative value curves of the output values ​​will be generated. The background computer will calculate the difference in the gap of the plate plane at each measurement point based on the value. Then, based on the height of the measurement point relative to the ground corresponding to the installation position value of the connector body 2, the corresponding data will be extracted separately. The required pitch of rotation will be calculated in reverse based on the data. The direction of rotation will be calculated based on the positive and negative values. Thus, after another movement, the rotation direction and number of rotations of the adjusting nut 25 at each installation position of the connector 2 can be directly output. The specific number of rotations can be accurate to a 5° angle, thereby realizing intelligent measurement and adjustment, and improving adjustment efficiency and accuracy.

[0036] Specifically, the passive running direction of the displacement sensor 37 is perpendicular to the running direction of the main drive wheel 33. The displacement sensor 37 is a linear displacement sensor that can measure the displacement difference between the fixed frame 31 and the driven member 35 by measuring the amount of extension and retraction.

[0037] Specifically, a controller is mounted on the back of the fixed frame 31. The controller is electrically connected to the displacement sensor 37. A drive motor is mounted inside the main guide wheel 33. The drive motor is electrically connected to the controller. The main guide wheel 33 is elongated and its outer wall is divided into left and right parts. Each left and right part is equipped with a drive motor. The speed, angle, and direction of rotation of the drive motor can be controlled by a computer. The structure on both sides can adjust the speed and direction. The position of the main guide wheel 33 can be changed by the difference in speed and direction, thereby controlling the position and orientation calibration of the fixed frame 31. It can achieve precise walking movements on the inner wall of the reference template. An extension rod is mounted on the outside of the connecting rod 34. The extension rod can be equipped with a pointer or a visual recognition device, which is used to guide the movement of the device inside the seam or directly identify the direction and position of the seam to assist in the direction control of the main guide wheel 33. The visual recognition device is an image recognition device based on AI algorithms. It calculates the seam position by using the difference between the seam position and the color, shadow, etc. of the inner wall of the template 1 to assist in the control of the walking direction of the main guide wheel 33.

[0038] The pointer-type control method involves a freely moving, sharp pointer passively moving inside the gap. The top of the pointer is hinged to an extension rod outside the connecting rod 34. A pressure switch is located at the pointer's top and hinged position, measuring the pointer's deflection direction. Through contact recognition, after one pressure switch reads a value, it determines that the pointer is pressed towards that switch position and calculates the pressure value. Due to the hinge and lever principle, the actual pointer position deflects in the opposite direction to the pressure switch. Since the device's movement direction is opposite to the gap's direction, the gap's direction forces the pointer to deflect in the opposite direction. Therefore, the pressure switch position is the opposite direction of the device's calibration direction. Thus, after recognizing the deflection between the device's movement direction and the gap's direction, the control... The controller receives the pressure value and pressure direction. The controller will control the main guide wheel 33 to rotate the traveling direction of the fixed frame 31 in the opposite direction of the pressure switch, so that the traveling direction of the equipment tends to reduce the pressure value of the pressure switch, and preferably makes the pressure switch have no value output. The rotation angle is determined according to the pressure value. The larger the pressure value, the larger the rotation angle. This value is proportional. Therefore, the output values ​​of the two sets of pressure switches on the left and right are always kept within a certain range of signal logic values ​​in the computer. Then the fixed frame 31 is in the correct traveling direction. When the value exceeds this range, the controller will intervene and deflect the direction so that the value returns to the range within the value range. Therefore, through this operation, it can be ensured that the seam inspector 3 can travel along the direction of the seam, and thus it can also be adapted to the template 1 with a curved surface.

[0039] A construction method for laying formwork in building casting includes the following steps:

[0040] Step A: Prepare template 1. Based on the shape of the building to be cast, use BIM technology to accurately determine the specific shape, curvature, size, and splicing joint position of the template. After the design is completed, make the corresponding template 1 according to the data size. The manufacturing process mainly includes cutting and welding. After cutting the plate, weld the edge joint fixing strips. And according to the template area and the volume and density of the internal cast body, add reinforcing ribs to support the internal pressure during casting.

[0041] Step B: Construction preparation. After excavating the foundation pit, the pile foundation and ground foundation are poured, and the internal steel reinforcement of the poured body is constructed.

[0042] Step C: Assemble template 1. Determine the calibration point position for pouring the outer formwork based on the position of the pile foundation and the steel reinforcement frame. Position and install the template 1 with calibration standard according to the calibration point position. Then assemble template 1 on both sides according to the reference position. During assembly, after aligning the joint positions, insert the connecting screw 21 into the inside of the fixing hole. Then screw the fixing nut 22 on the innermost side of the connecting screw 21 for initial fixation and maintain the initial positioning between the two adjacent templates. Then, attach the adjusting piece 23 to the outer side of the fixing nut 22. Then, insert the wedge 24 between the outer plate of template 1 and the connecting screw 21. Finally, screw the adjusting nut 25 into the outermost side of the wedge 24.

[0043] Step D: Adjust the flatness of the inner plate of template 1. Use a combination of steel cable and electric cable to connect the joint inspector 3 mechanically and electrically. Then place the joint inspector 3 at the bottom of the inner wall of template 1 and start the equipment. The main drive wheel 33 is driven by the drive motor and moves. The magnetic block 32 generates magnetic force and adheres to the inner wall of template 1. As the main drive wheel 33 moves upward, the entire equipment moves upward along the inner wall of template 1, which serves as the reference. During the movement, the uneven position of the newly installed inner wall of template 1 will cause the driven part 35 to move relative to the fixed frame 31. The displacement sensor 37 records the position in real time. Finally, according to the deviation position of the inner wall of the joint position, rotate the adjusting nut 25 to move the wedge 24 inward or outward to adjust the staggered position of the joint position. After the adjustment is completed, tighten the fixing nut 22 to achieve positioning.

[0044] Step E: After the template is fixed, pour the inner cavity of template 1.

[0045] Specifically, in step A, the density of the reinforcing ribs at the bottom of template 1 is greater than that at the top of template 1. The design density of the reinforcing ribs needs to be based on the characteristics of fluid height pressure. The number of ribs at the bottom should be densely distributed, while the number at the top should be sparse. This ensures that the pressure per square meter can support the inner wall of template 1 and keep it flat. Furthermore, the reinforcing ribs should be welded using a cooling welding method to ensure that the plate does not deform after welding.

[0046] Specifically, in step C, before adjusting the inner and outer positions of two adjacent templates, it is necessary to adjust the bottom position of the two adjacent templates 1. The bottom anchor rod is used to adjust the horizontal position and level the bottom. The bottom of the template can be leveled by adjusting the screw-in nut or by adjusting the shim. It is necessary to ensure that the bottom of all assembled adjacent templates is at the same horizontal baseline position.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
