Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ditch construction, in particular to a rectangular ditch construction device. BACKGROUND

[0002] In the construction of a rectangular ditch, there is a lack of a special and efficient device for supporting the formwork in the tunnel. Usually, a relatively simple support method is relied on, such as a temporarily built simple support or the use of scattered support components, which are difficult to ensure the stability of the formwork during the construction process. Due to the lack of effective support mechanisms, the formwork is prone to displacement and deformation under the lateral pressure of the concrete during concrete pouring, which may result in inaccurate structural dimensions of the ditch, unsmooth lines, and poor appearance quality. At the same time, this unstable support method also increases the safety risk during the construction process, because the formwork may collapse and cause harm to the construction personnel. Moreover, the traditional support method is relatively cumbersome to install and adjust, which requires a large amount of time and labor, reduces the construction efficiency, increases the construction cost, and cannot meet the demand for efficient and high-quality construction in the rapid development of modern infrastructure.

[0016] In the rectangular trench construction device provided in the application, the abutting arm is connected to the middle position of the support and is inclined towards the sliding assembly, and a rubber pad is arranged outside the abutting arm.

[0017] The support mechanism in the application is arranged on the support and can provide stable and reliable support for the formwork in the tunnel. By cooperation of the fixed edge and the sliding assembly, the formwork is tightly clamped, effectively resisting the lateral pressure generated during concrete pouring, ensuring that the formwork remains in a fixed position during construction, thereby ensuring that the structure size of the trench is accurate, and the finally formed trench meets the design requirements.

[0037] Reference Figs. 1-2 A rectangular side ditch construction device includes a main beam, a side connected to the main beam, and a sliding side in sliding connection with the main beam, and a clamping groove with a width controllable by sliding the sliding side is formed between the side and the sliding side.

[0038] The main beam provides an overall support frame as the main load-bearing structure. The side edges are connected to the main beam and together with the sliding edges form a structure for clamping the formwork. The sliding edges can slide along the main beam, and by changing the relative position between the sliding edges and the side edges, the width of the clamping groove is adjusted. In use, the formwork is placed in the clamping groove, and the sliding edges are slid according to the width of the formwork to tightly fit the two sides of the formwork, thereby achieving stable clamping of the formwork. It can adapt to formworks of different widths, improving the versatility of the device. By adjusting the sliding of the sliding edges, it can ensure that the formwork is firmly fixed during construction, ensuring the accuracy of the formwork position, which helps to improve the precision and quality of the trench construction, and the operation is relatively simple, facilitating quick adjustment and installation by construction personnel.

[0039] The application provides a rectangular trench construction device, which comprises a support 10; a support mechanism 20 arranged on the support 10 and used for supporting the formwork in the tunnel.

[0040] The support 10 provides a basic support platform for the entire device, and the support mechanism 20 is installed on the support 10, which is designed to effectively support the formwork in the tunnel. During construction, the support 10 is placed in the appropriate position, and the support mechanism 20 directly contacts and applies a support force to the formwork to resist various forces generated on the formwork during concrete pouring, thereby maintaining the stable state of the formwork. The support mechanism 20 provides special support for the formwork in the tunnel, enhancing the stability of the formwork during construction. Compared with the traditional method without a special support mechanism 20, it can better ensure the accuracy of the trench structure size and reduce quality problems caused by deformation of the formwork. At the same time, it helps to improve the construction efficiency, because stable formwork support can reduce the adjustment and repair work during construction.

[0041] It should be noted that the formwork includes two, forming a structure similar to a rectangular box, and the two formworks are poured with concrete, and after molding, a cement wall is formed.

[0042] The support mechanism 20 includes a fixed edge 30, a sliding assembly 40, and a locking mechanism 50. The fixed edge 30 is connected to one side of the support 10, the sliding assembly 40 is slidingly connected to the support 10, the sliding assembly 40 cooperates with the fixed edge 30 to clamp the formwork, and the locking mechanism 50 can lock the sliding assembly 40 after the sliding assembly 40 slides to the clamping position.

[0043] The fixed edge 30 is used to support one side of the formwork, and the sliding assembly 40 supports the other side of the formwork.

[0044] The fixed edge 30 is fixed on the support 10 as a support and positioning reference on one side of the formwork. The sliding assembly 40 can slide on the support 10, and through relative movement with the fixed edge 30, the clamping of formworks of different widths is realized. When the sliding assembly 40 slides to the appropriate position and the formwork is tightly clamped between the fixed edge 30 and the sliding assembly 40, the locking mechanism 50 acts to lock the sliding assembly 40 in this position to prevent displacement during construction. Through the connection relationship with the sliding assembly 40 and the support 10, the locking mechanism 50 generates friction or mechanical restraint to ensure that the sliding assembly 40 remains fixed.

[0045] The clamping force and position of the formwork can be accurately adjusted to adapt to formworks of various sizes, improving the flexibility and adaptability of the device. The locking mechanism 50 ensures the stability of the formwork support during concrete pouring and other construction processes, effectively preventing the formwork from loosening or shifting, thereby ensuring the construction quality of the ditch and reducing defects caused by formwork movement.

[0046] In some embodiments, the support mechanism 20 includes two, one on each end of the support 10.

[0047] The arrangement of the two support mechanisms 20 allows for one-time construction clamping of the two opposite cement walls in the ditch.

[0048] The fixed edge 30 is a reverse triangular frame structure connected to the end of the support 10, and the hypotenuse of the fixed edge 30 is in close contact with the side of the tunnel slope, forming a support.

[0049] The fixed edge 30 of the reverse triangular frame structure is designed to fit the shape of the side of the tunnel slope. During installation, the fixed edge 30 is connected to the end of the support 10 and placed in the tunnel, with the hypotenuse in close contact with the side of the slope. In this way, when the formwork is subjected to concrete pressure, the fixed edge 30 not only provides lateral support to the formwork through its own structure, but also transfers part of the pressure to the tunnel slope by fitting with the side of the slope, forming a stable support force distribution.

[0050] The structural characteristics of the tunnel slope are fully utilized, increasing the stability and reliability of the support. The pressure borne by the support 10 and the fixed edge 30 alone is reduced, reducing the risk of damage or deformation of the device. At the same time, it can better ensure the installation accuracy of the formwork at the slope position, effectively improving the construction quality of the ditch at the slope section, and ensuring the fit of the ditch line with the slope.

[0051] The sliding assembly 40 includes a sliding rail 401, a sliding seat 402, and a blocking piece 403. The sliding rail 401 is connected to the support 10, the sliding seat 402 is slidingly connected to the sliding rail 401, and the blocking piece 403 is connected to the sliding seat 402.

[0052] The slide rail 401 is fixed on the bracket 10 to provide a sliding track for the slide base 402. The slide base 402 can slide freely along the slide rail 401, and the distance between the slide base 402 and the fixed edge 30 is adjusted by the movement of the slide base 402 to adapt to templates of different widths. The stopper 403 is connected with the slide base 402, and when the slide base 402 slides to the appropriate position, the stopper 403 cooperates with the fixed edge 30 to clamp the template. The sliding connection between the slide base 402 and the slide rail 401 ensures smoothness and accuracy of sliding, making the template clamping operation more convenient.

[0053] The sliding assembly 40 realizes flexible adjustment of the clamping width of the template, and the operation is simple and convenient. The cooperation of the slide rail 401 and the slide base 402 ensures the stability and accuracy of sliding, reducing the problem of unstable clamping of the template caused by unsmooth or deviated sliding. The existence of the stopper 403 increases the contact area and clamping force with the template, improves the reliability of template fixation, and helps to ensure the stability of the template during construction.

[0054] The slide rail 401 is fastened and connected on the bracket 10 through the mounting hole on the bracket 10, and the slide rail 401 extends out of the two side surfaces of the bracket 10. The slide base 402 is slidingly connected with the protruding part of the bracket 10.

[0055] The slide rail 401 is fastened and installed through the mounting hole on the bracket 10, ensuring the firm fixation of the slide rail 401 on the bracket 10. The slide rail 401 extends out of the two side surfaces of the bracket 10 to provide sufficient sliding space for the slide base 402. The slide base 402 is slidingly connected with the protruding part of the bracket 10. This structural design enables the slide base 402 to maintain a stable motion trajectory during sliding and can fully utilize the length of the slide rail 401 for position adjustment. During installation and adjustment, the construction personnel can conveniently move the slide base 402 according to the width of the template to make it slide smoothly on the protruding part of the bracket 10.

[0056] The stability of the connection between the slide rail 401 and the bracket 10 is enhanced, ensuring the reliability of the sliding assembly 40 during operation. The slide rail 401 extending out of the two side surfaces of the bracket 10 provides a larger adjustment range for the slide base 402, improving the adaptability of the device to templates of different widths. The sliding connection of the slide base 402 with the protruding part of the bracket 10 makes the sliding of the slide base 402 more stable, reducing shaking and deviation, which helps to accurately adjust the template clamping position and improve the construction precision.

[0057] In some embodiments, the locking mechanism 50 includes a base 501, a first branch arm 502, a telescopic branch arm 503, and an abutting arm 504. The base 501 is connected to the sliding assembly 40, the first branch arm 502 is hinged to the base 501, the telescopic branch arm 503 is hinged to the first branch arm 502, and the abutting arm 504 is connected to the bracket 10. After adjusting the length of the telescopic branch arm 503, it can abut against the abutting arm 504.

[0058] The base 501 is connected with the sliding assembly 40 and moves with the sliding assembly 40. The first supporting arm 502 is hinged with the base 501 and can rotate at a certain angle around the hinge point. The telescopic supporting arm 503 is hinged with the first supporting arm 502. By adjusting the length of the telescopic supporting arm 503, the overall extension state of the telescopic supporting arm 503 can be changed. When the sliding assembly 40 slides to the appropriate position of clamping the formwork, the length of the telescopic supporting arm 503 is adjusted to make the end of the telescopic supporting arm 503 abut against the abutment arm 504. At this time, the first supporting arm 502, the telescopic supporting arm 503 and the abutment arm 504 form a stable triangular structure, and the sliding assembly 40 is locked at the current position by mechanical constraint.

[0059] A reliable locking mode is provided to ensure the stability of the sliding assembly 40 in the formwork clamping position. The triangular structure has good stability and can effectively resist external force interference in the construction process to prevent the sliding assembly 40 from sliding accidentally and ensure the stable support of the formwork in the concrete pouring process, thereby ensuring the quality of the ditch construction and reducing the quality problems caused by the movement of the formwork.

[0060] Meanwhile, the telescopic supporting arm 503 can be pulled by the staff outside the tunnel, which is convenient for operation. Meanwhile, the telescopic supporting arm 503 is rotated and adjusted to the appropriate length, and then the telescopic supporting arm 503 is abutted against the abutment arm 504. At this time, since the blocking piece 403 abuts against the formwork along with the sliding assembly 40, when the telescopic supporting arm 503 is abutted against the abutment arm 504, it is equivalent to giving the blocking piece 403 the force of abutting against the formwork again, so that the blocking piece 403 is fixed.

[0061] The telescopic supporting arm 503 includes the second supporting arm 506 and the bolt 505. The second supporting arm 506 is hinged with the first supporting arm 502, and the bolt 505 is threadedly connected with the second supporting arm 506. The bolt 505 is connected at one end of the second supporting arm 506 and is installed in the same direction as the extension direction of the second supporting arm 506. Rotating the bolt 505 can make the bolt 505 extend or retract along the extension direction of the second supporting arm 506.

[0062] The second supporting arm 506 is hinged with the first supporting arm 502 to constitute the main structure of the telescopic supporting arm 503. The bolt 505 is threadedly connected with the second supporting arm 506 and is installed in the same direction as the extension direction of the second supporting arm 506. When it is necessary to adjust the length of the telescopic supporting arm 503, the bolt 505 is rotated. Due to the thread, the bolt 505 will move along the extension direction of the second supporting arm 506. If the bolt 505 is rotated outward, the second supporting arm 506 will be pushed to extend. Conversely, rotating inward will make the second supporting arm 506 shorten. The length of the telescopic supporting arm 503 is accurately adjusted in this way to realize accurate abutment with the abutment arm 504 and complete the locking or unlocking of the sliding assembly 40.

[0063] The length of the telescopic support arm 503 can be precisely adjusted, and the operation is simple and convenient. The construction personnel can quickly and accurately adjust the length of the telescopic support arm 503 according to actual needs by rotating the bolt 505, so as to adapt to different installation and locking requirements. Such precise adjustment helps to improve the reliability and stability of the locking mechanism 50, further ensures the stability of the formwork support, and ensures the quality and precision of the trench construction.

[0064] The abutting arm 504 is connected at the middle position of the support 10 and is inclined towards the sliding assembly 40, and the outer side of the abutting arm 504 is provided with a rubber pad.

[0065] The abutting arm 504 is connected at the middle position of the support 10 and is inclined towards the sliding assembly 40, and the outer side of the abutting arm 504 is provided with a rubber pad.

[0066] The abutting arm 504 is connected at the middle position of the support 10 and is inclined towards the sliding assembly 40, and the outer side of the abutting arm 504 is provided with a rubber pad.

[0067] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
