Description

Technical Field

[0001] This application belongs to the field of building formwork installation technology, specifically relating to a building formwork installation error compensation device. Background Technology

[0002] Construction formwork is a temporary template used for concrete pouring and shaping. Formwork is mostly modular and assembled. Small errors in a single formwork piece can accumulate through splicing, often leading to excessive deviations in the overall structure. Therefore, error compensation must be used to eliminate the cumulative effect. If there are cumulative errors in the installation of the formwork, the dimensions of the poured concrete structure will not meet the design requirements, affecting the load-bearing performance of the components.

[0003] A search revealed a building formwork installation device and method with publication number CN114961258A. This device enables the re-measurement and adjustment of the verticality and horizontality of the formwork, as well as the measurement and adjustment of the horizontality of the strip formwork. However, the components used to support the formwork are located outside the formwork, and the components have a large number of concave surfaces. When concrete is poured onto the formwork, it impacts the formwork, causing it to separate from the bottom formwork. This results in the concrete coming into contact with the components outside the formwork. After the concrete hardens, some of the component surfaces retain hardened concrete. This concrete is not only difficult to clean, but it also affects the reusability of the installation equipment. Summary of the Invention

[0004] This application provides a building formwork installation error compensation device, which realizes the installation of building formwork and the lateral and / or longitudinal compensation of installation errors by setting a base plate, a support component, a lateral sliding component and a longitudinal sliding component.

[0005] To achieve the above-mentioned objectives, this application provides the following technical solution:

[0006] According to one aspect of this application, a building formwork installation error compensation device is provided, which includes a base plate, the upper surface of which is provided with a support assembly for installing the formwork, and the support assembly is provided with a lateral sliding assembly and a longitudinal sliding assembly for controlling the lateral and longitudinal sliding of the formwork, respectively.

[0007] The support assembly includes multiple sliding plates, each sliding plate having multiple mold shells on its upper surface. Each mold shell has a cylinder and a rod adapted to the cylinder on its inner side. The cylinder is fixed at the top center of the inner wall of the mold shell, and has an air hole at its upper end. Two collars are movably sleeved on the outer side of the rod. Two connecting rods are symmetrically fixed on the outer wall of the collars. A support rod is fixed at the other end of the connecting rod. The upper surface of the support rod has two inclined surfaces, and the inclined surfaces of the four support rods respectively match the four corners of the inner wall of the mold shell.

[0008] The lateral sliding assembly includes a fixing strip fixed laterally to the upper surface of the slide plate and notches respectively opened on both sides of the bottom of each mold shell. Multiple matching U-shaped blocks are snapped onto the upper surface of the fixing strip. The top of the U-shaped blocks is fixedly connected to the lower end of the insert rod, and threaded holes are opened on both sides of the blocks. A screw is provided inside the threaded holes.

[0009] The longitudinal sliding assembly includes a U-shaped frame longitudinally fixed to the upper surface of the base plate and a groove formed at the bottom of the slide plate. The U-shaped frame is engaged with the inner side of the groove. At least two extrusion ports are formed on the inner wall of the U-shaped frame, and an extrusion block is engaged in the extrusion port. A matching insert plate is inserted into the inner side of the U-shaped frame. At least two oblique grooves corresponding to the extrusion block are formed on the side wall of the insert plate corresponding to the extrusion block.

[0010] In this configuration, the notches on both sides of the bottom of each mold shell are respectively engaged with the outer side of the fixing strip, the cylindrical sleeve is engaged with the outer side of the corresponding insert rod, the inclined surfaces on the upper surfaces of the four support rods are respectively engaged with the four corners of the inner wall of the mold shell, and the U-shaped block is fixed to the fixing strip by a screw.

[0011] As a further improvement to the technical solution of this application, a conical cylinder is fixedly provided at the lower end of the cylinder.

[0012] As a further improvement to the technical solution of this application, a knob is fixedly provided at one end of the screw located outside the U-shaped block.

[0013] As a further improvement to the technical solution of this application, a trapezoidal block is fixedly connected to one end of the insert plate.

[0014] As a further improvement to the technical solution of this application, the width of the insert plate is the same as the length of the distance between the inner walls of the U-shaped frame, and the inclined groove and the extrusion block are staggered.

[0015] Compared with the prior art, the building formwork installation error compensation device described in this application has the following advantages:

[0016] (1) This application achieves built-in stable support for the mold shell through the support components. Through the coordinated action of the cylinder, insert rod, collar, connecting rod and support rod on the inner wall of the mold shell, the inclined surface at the upper end of the support rod is closely fitted with the inner wall of the four corners of the mold shell, which can effectively resist the impact force during concrete pouring, prevent the mold shell from separating from the slide plate, reduce the contact between concrete and external components. Compared with the traditional external support structure, the built-in support can prevent concrete residue on the surface of the components, reduce the cleaning difficulty, significantly improve the reusability of the installation equipment, and at the same time ensure the structural stability of the mold shell during the pouring process and reduce the positional displacement caused by impact.

[0017] (2) This application achieves precise compensation for mold installation error through the cooperation of the transverse sliding component and the longitudinal sliding component. In the transverse sliding component, the threaded transmission structure of the knob, screw and U-shaped block can accurately adjust the transverse displacement of the mold. In the longitudinal sliding component, the linkage design of the insert plate, inclined groove and extrusion block can flexibly control the longitudinal position of the slide plate and stabilize the friction after fixing. The two work together to effectively eliminate the accumulation of small errors in a single mold, ensure that the overall structural dimensions meet the design requirements, improve the stress performance of concrete components, and solve the quality problem caused by excessive cumulative error in traditional assembly.

[0027] Please refer to Figure 1-7 This application discloses a building formwork installation error compensation device, which includes a base plate 1. The upper surface of the base plate 1 is provided with a support component 2 for installing the formwork. The support component 2 is provided with a lateral sliding component 3 and a longitudinal sliding component 4 for controlling the lateral and longitudinal sliding of the formwork, respectively.

[0028] The support assembly 2 includes multiple slide plates 21. Each slide plate 21 has multiple mold shells 22 on its upper surface. Each mold shell 22 has a cylinder 23 and a rod 25 that matches the cylinder 23 on its inner side. The cylinder 23 is fixed at the top center of the inner wall of the mold shell 22, and an air hole 24 is opened at its upper end. Two collars 27 are movably sleeved on the outer side of the rod 25. Two connecting rods 28 are symmetrically fixed on the outer wall of the collars 27. A support rod 29 is fixed at the other end of the connecting rod 28. Two inclined surfaces 210 are opened on the upper surface of the support rod 29. The inclined surfaces 210 on the upper surface of the four support rods 29 are respectively matched with the four corners of the inner wall of the mold shell 22.

[0029] The lateral sliding assembly 3 includes a fixing strip 31 that is laterally fixed to the upper surface of the slide plate 21 and notches 36 that are respectively opened on both sides of the bottom of each mold shell 22. Multiple matching U-shaped blocks 32 are snapped onto the upper surface of the fixing strip 31. The top of the U-shaped block 32 is fixedly connected to the lower end of the insert rod 25, and threaded holes 33 are opened on both sides of it. A screw 34 is provided inside the threaded hole 33.

[0030] The longitudinal sliding assembly 4 includes a U-shaped frame 41 longitudinally fixed to the upper surface of the base plate 1 and a groove 42 opened at the bottom of the slide plate 21. The U-shaped frame 41 is engaged inside the groove 42. At least two extrusion ports 43 are opened on the inner wall of the U-shaped frame 41. An extrusion block 44 is engaged in the extrusion port 43. A matching insert plate 45 is inserted into the inner side of the U-shaped frame 41. At least two inclined grooves 46 corresponding to the extrusion block 44 are opened on the side wall of the insert plate 45. The width of the insert plate 45 is the same as the distance between the inner walls of the U-shaped frame 41. The inclined grooves 46 and the extrusion block 44 are staggered. The extrusion block 44 is pushed into the extrusion port 43 by the inclined grooves 46, so that the extrusion block 44 can be stably engaged in the extrusion port 43.

[0031] In this configuration, the notches 36 on both sides of the bottom of each mold shell 22 are respectively engaged with the outer side of the fixing strip 31, the cylinder 23 is sleeved with the outer side of the corresponding insert rod 25, the inclined surface 210 on the upper surface of the four support rods 29 is respectively engaged with the four corners of the inner wall of the mold shell 22, and the U-shaped block 32 is fixed with the fixing strip 31 by the screw 34, thereby making the mold shell 22 engaged with the slider 21.

[0032] In a preferred embodiment, a tapered cylinder 26 is fixedly provided at the lower end of the cylinder 23 to facilitate the connection between the cylinder 23 and the insertion rod 25.

[0033] In a preferred embodiment, a knob 35 is fixedly provided at one end of the screw 34 located outside the U-shaped block 32 to facilitate the rotation of the screw 34.

[0034] In a preferred embodiment, a trapezoidal block 47 is fixedly connected to one end of the insert plate 45 to facilitate the insertion of the insert plate 45 into the inside of the U-shaped frame 41.

[0035] In application, firstly, the mold shell 22 is snapped onto the upper surface of the slide plate 21 to ensure that the position of the mold shell 22 is initially aligned. At this time, the cylinder 23 at the center of the inner wall of the mold shell 22 is in a vertical state. Under the action of gravity, the cylinder 23 is fitted onto the outside of the insert rod 25. The collar 27 slides downward on the surface of the insert rod 25 under the action of gravity. As the insert rod 25 is inserted into the cylinder 23, the connecting rod 28 drives the support rod 29 to unfold towards the four corners of the mold shell 22. Because the two inclined surfaces 210 at the upper end of the support rod 29 are aligned with the four corners of the mold shell 22, The inner wall of the support rod 29 is matched with the inner wall of the mold shell 22. When the support rod 29 is fully extended, the inclined surface 210 fits tightly with the inner wall of the mold shell 22, forming a stable support for the mold shell 22. At the same time, the air hole 24 at the upper end of the cylinder 23 can balance the internal air pressure and prevent the insertion rod 25 from being hindered by air pressure. This built-in support structure is located inside the mold shell 22, which can effectively resist the impact force during concrete pouring, prevent the mold shell 22 from separating from the slide plate 21, reduce the risk of concrete contacting external components, and improve the equipment reuse rate.

[0036] When it is necessary to adjust the lateral position of the mold shell 22 to compensate for installation errors, the knob 35 can be turned to drive the screw 34 to rotate in the threaded hole 33. Since one end of the screw 34 is in contact with the fixing strip 31, the thrust generated by the rotation will push the U-shaped block 32 to slide along the length of the fixing strip 31. The U-shaped block 32 drives the upper collar 27 and other components to move synchronously through the insert rod 25. The notches 36 on both sides of the mold shell 22 slide along the fixing strip 31 to ensure stable movement. By controlling the rotation angle of the knob 35, the lateral displacement of the mold shell 22 can be precisely adjusted (the adjustment accuracy can reach ±1mm), thereby eliminating lateral installation errors. After the adjustment is completed, the mold shell 22 is installed. The screw 34 and the fixing strip 31 are tightly abutted, and the position of the U-shaped block 32 is fixed by friction to prevent the mold shell 22 from shifting during the casting process.

[0037] When it is necessary to compensate for the longitudinal installation error of the mold shell 22, the trapezoidal block 47 is pushed to drive the insert plate 45 to slide inside the U-shaped frame 41. Since the inclined groove 46 of the insert plate 45 and the extrusion block 44 are staggered, when the insert plate 45 moves, the inner wall of the inclined groove 46 will squeeze the extrusion block 44, causing the extrusion block 44 to partially pop out from the extrusion port 43 and press against the inner wall of the groove 42 at the bottom of the slide plate 21. By controlling the insertion depth of the insert plate 45, the pop-out amount of the extrusion block 44 can be adjusted, thereby controlling the sliding resistance of the slide plate 21 along the length of the U-shaped frame 41. When it is necessary to move the slide plate 21, the slide plate 21 is pushed to make the groove 42 slide along the U-shaped frame 41 to achieve the longitudinal position adjustment of the mold shell 22. After the adjustment is in place, the insert plate 45 is pushed to make the extrusion block 44 completely press against the groove 42, and the slide plate 21 is fixed by friction to complete the longitudinal error compensation.
