Description

[0001] The present invention relates to the technical field of civil engineering and in particular to a device for crack-free concreting.

[0002] A crack-free concreting device is used to prevent cracks in the ground after concreting. Cracks arise from physical structural changes in the concrete structure, caused by internal and external influences. These cracks are the primary cause of reduced load-bearing capacity, durability, and watertightness in concrete structures.

[0003] In current technology, the introduction of expansion joints in the ground is usually used to prevent cracks from forming in the ground after concreting due to various factors.

[0004] According to current technology, when creating cut joints, the concrete surface is typically processed by an operator using a handheld saw. This process is not only time-consuming and labor-intensive, but also requires constant adjustment of the cutting position by the operator, which can easily lead to gaps at the cut edges in the concrete and thus impair the effectiveness of crack prevention. Therefore, we propose a device for crack-free concreting during the concreting process.

[0005] The object of the present invention is to provide a device for crack-free concreting, thereby solving the problems raised in the prior art above.

[0006] To solve the aforementioned problem, the invention offers the following technical solutions: A device for crack-free concreting, comprising a mounting plate; a rectangular groove arranged in the mounting plate; and a transverse motion assembly arranged on the top of the mounting plate, wherein the transverse motion assembly comprises a support frame arranged in the rectangular groove, wherein a T-shaped groove is provided inside the support frame, wherein the inner wall of the T-shaped groove is rigidly connected to an electric push rod, wherein the output end of the electric push rod is rigidly connected to a T-shaped block, wherein the outer wall of the T-shaped block is slidably connected to the inner wall of the T-shaped groove, wherein a mounting bracket is rigidly connected to the underside of the T-shaped block, wherein the lower inner wall of the mounting bracket is rigidly connected to a drive motor, wherein the drive motor is rigidly connected at the output end to an output shaft, and wherein a saw blade is rigidly connected to the outer wall of the end face of the output shaft.The arrangement of the transverse movement assembly allows the operator to extend the end of the electric push rod by actuating it, thus moving the T-shaped block laterally along the inner wall of the T-shaped groove. This moves the mounting bracket, the drive motor, and the saw blade beneath the T-shaped block laterally, thereby adjusting the cutting position of the saw blade in the concrete and improving the effectiveness of the device.

[0007] Preferably, a lifting assembly is attached to the top of the mounting plate, the lifting assembly comprising a mounting column rigidly connected to the top of the mounting plate, the top of the mounting column being rigidly connected to a cover plate, a cylinder being attached to the lower center of the cover plate, the outlet end of the cylinder being rigidly connected to a lifting plate, a limiting block being attached to the outer wall of the lifting plate, the inner wall of the end face of the limiting block being slidably connected to a limiting rod, the top of the limiting rod being rigidly connected to the underside of the cover plate, and the underside of the lifting plate being rigidly connected to the top of the support frame. The arrangement of the lifting assembly allows the cutting depth of the saw blade in the joint to be adjusted when sawing joints in concrete using a saw blade.The operator activates the cylinder, causing the cylinder's outlet end to extend downwards and the lifting plate to move downwards. As the lifting plate descends, the saw blade beneath it moves downwards simultaneously, allowing the saw blade's cutting depth to be adjusted within the joint. Simultaneously, the limit block along the outer wall of the limit bar moves downwards, enhancing the lifting plate's stability during the lifting process.

[0008] Preferably, four casters are firmly attached to the underside of the mounting plate, with each of the four casters located at one of the four corners of the underside of the mounting plate. The four casters attached to the bottom of the mounting plate facilitate the mobility of the device.

[0009] Preferably, a handle is firmly attached to the top of the mounting plate.

[0010] Preferably, the outer wall of the top of the T-shaped block is adapted to the inner wall of the T-shaped groove.

[0011] Preferably, the number of boundary blocks is four, with the four boundary blocks being located at each of the four corners of the lifting plate.

[0012] The present invention provides a device for crack-free concreting. The device for crack-free concreting has the following advantageous effects: A device for crack-free concreting, incorporating a transverse movement assembly to prevent cracking in the concrete, requires cutting the dried concrete after the pouring process is complete. To cut the concrete, the operator activates the drive motor, which sets the output shaft in rotation. As the output shaft rotates, the saw blade is driven into rotation, creating cuts in the concrete. During the cutting process, if the position of the cut in the concrete needs to be adjusted, the operator actuates the electric push rod, extending the output end of the electric push rod and moving the T-shaped block transversely along the inner wall of the T-shaped groove.This causes the mounting bracket, drive motor and saw blade to move transversely beneath the T-shaped block to adjust the position of the saw blade's cutting edge on the concrete, thus increasing the efficiency of the device.

[0013] The lifting assembly's design allows the saw blade to adjust the cutting depth within the joint when sawing concrete joints. The operator activates the cylinder, causing its end to extend downwards and the lifting plate to move downwards. As the lifting plate descends, the saw blade beneath it moves downwards simultaneously, allowing the cutting depth to be adjusted within the joint. Simultaneously, the limiting block along the outer wall of the limiting bar moves downwards, improving the lifting plate's stability during the lifting process. Fig. Figure 1 is a schematic representation of the three-dimensional structure of the present invention. Fig. Figure 2 is a partial sectional view of the present invention. Fig. Figure 3 is a partial sectional view of the transverse movement assembly of the present invention. Fig. Figure 4 is a partial sectional view of the lifting assembly in the present invention.

[0014] To better understand the technical features, objectives and effects of this invention, the specific embodiment is explained below with reference to the accompanying figures.

[0015] As it is in the Fig. 1, Fig. 2, Fig. 3 to Fig. As shown in Figure 4, the present invention comprises the following two specific embodiments. Example 1

[0016] Concreting device for crack-free concreting, comprising a mounting plate 1; a rectangular groove 5 arranged in the mounting plate 1; and a transverse motion assembly 41 arranged on the upper side of the mounting plate 1, characterized in that the transverse motion assembly 41 comprises a support frame 411 arranged in the rectangular groove 5, wherein a T-shaped groove 412 is provided inside the support frame 411, wherein the inner wall of the T-shaped groove 412 is rigidly connected to an electric push rod 413, wherein the output end of the electric push rod 413 is rigidly connected to a T-shaped block 414, wherein the outer wall of the T-shaped block 414 is slidably connected to the inner wall of the T-shaped groove 412, wherein a mounting bracket 415 is rigidly connected to the underside of the T-shaped block 414, wherein the lower inner wall of the mounting bracket 415 is rigidly connected to a drive motor 416, wherein the drive motor 416 is rigidly connected at its output end to an output shaft 417,wherein a saw blade 418 is firmly attached to the outer wall of the end face of the output shaft 417;

[0017] The arrangement of a transverse movement assembly 41 serves to prevent cracking in the concrete, whereby the dried concrete must be cut after the concreting process is complete. When cutting the concrete, the operator activates the drive motor 416, which sets the output shaft 417 into rotation. As the output shaft 417 rotates, the saw blade 418 is driven into rotation, enabling the saw blade 418 to create cuts in the concrete. During the cutting process, if the position of the cut in the concrete needs to be adjusted, the operator actuates the electric push rod 413, which extends the output end of the electric push rod 413 and moves the T-shaped block 414 transversely along the inner wall of the T-shaped groove 412.This causes the mounting bracket 415, the drive motor 416 and the saw blade 418 to move transversely below the T-shaped block 414 in order to adjust the position of the cutting edge of the saw blade 418 on the concrete and thus increase the efficiency of the device;

[0018] Rollers 2 are firmly attached to the underside of the mounting plate 1, with the number of rollers 2 being four, each located at one of the four corners of the underside of the mounting plate 1. The four rollers 2 attached to the bottom of the mounting plate 1 facilitate the mobility of the device; A handle 3 is firmly attached to the top of the mounting plate 1;

[0019] The outer wall of the top of the T-shaped block 414 is adapted to the inner wall of the T-shaped groove 412. Example 2

[0020] In contrast to embodiment 1, this embodiment discloses a lifting assembly as shown in Fig. 4 shown: A lifting assembly 42 is attached to the top of the mounting plate 1, the lifting assembly 42 comprising a mounting column 421 fixedly connected to the top of the mounting plate 1, the top of the mounting column 421 being fixedly connected to a cover plate 422, a cylinder 423 being attached to the lower center of the cover plate 422, the outlet end of the cylinder 423 being fixedly connected to a lifting plate 424, a limiting block 425 being attached to the outer wall of the lifting plate 424, the inner wall of the end face of the limiting block 425 being slidably connected to a limiting rod 426, the top of the limiting rod 426 being fixedly connected to the underside of the cover plate 422, and the underside of the lifting plate 424 being fixedly connected to the top of the support frame 411.The arrangement of the lifting assembly 42 allows the cutting depth of the saw blade 418 to be adjusted in the joint when sawing joints in concrete using the saw blade 418. The operator actuates the cylinder 423, causing the end of the cylinder 423 to extend downwards and the lifting plate 424 to move downwards. As the lifting plate 424 moves downwards, the saw blade 418 located below it moves downwards synchronously, allowing the cutting depth of the saw blade 418 in the joint to be adjusted. While the lifting plate 424 moves downwards, the limiting block 425 moves downwards synchronously along the outer wall of the limiting rod 426, thereby improving the stability of the lifting plate 424 during the lifting process. There are four limiting blocks 425, each located at one of the four corners of the lifting plate 424.

[0021] Operating principle: To prevent cracking in the concrete, the dried concrete must be cut after it has been poured. When cutting the concrete, the operator activates the drive motor 416, which sets the output shaft 417 into rotation. As the output shaft 417 rotates, the saw blade 418 is driven into rotation, enabling it to create cuts in the concrete. During the cutting process, if the position of the cut needs to be adjusted, the operator operates the electric push rod 413. This extends the output end of the electric push rod 413 and moves the T-shaped block 414 transversely along the inner wall of the T-shaped groove 412. This causes the mounting bracket 415, the drive motor 416, and the saw blade 418 to move transversely beneath the T-shaped block 414, adjusting the position of the saw blade 418's cut on the concrete and thus increasing the efficiency of the device.

[0022] When sawing joints in concrete using saw blade 418, the cutting depth of the saw blade 418 must be adjusted within the joint. The operator actuates the cylinder 423, causing the end of the cylinder 423 to extend downwards and the lifting plate 424 to move downwards. As the lifting plate 424 moves downwards, the saw blade 418 located beneath it moves downwards synchronously, allowing the cutting depth of the saw blade 418 within the joint to be adjusted. While the lifting plate 424 moves downwards, the limiting block 425 moves downwards synchronously along the outer wall of the limiting rod 426, thereby improving the stability of the lifting plate 424 during the lifting process.
