Description

Technical Field

[0001] This application relates to the field of non-chiseling concrete mold technology, for example to a novel non-chiseling concrete mold for construction joints. Background Technology

[0002] Construction joint chiseling-free concrete mold is an innovative construction tool designed to improve construction efficiency and the quality of concrete structures. Cement needs to be poured in sections, and the construction joint formed between the first and second poured concrete sections requires manual roughening, which wastes a lot of time and labor. After demolding, the construction joint chiseling-free concrete mold can form a rough surface on the cement surface, which facilitates the formation of interlocking resistance after the later cement is poured.

[0003] In the existing technology, the construction joint chisel-free concrete mold has several sharp protrusions on the pouring side. After demolding, it forms pits on the concrete surface to replace the rough surface. However, after the cement solidifies, the sharp protrusions on the pouring side of the concrete mold are not easy to separate from the concrete. Forced removal will damage the concrete mold. Therefore, a new type of construction joint chisel-free concrete mold is proposed to solve the above problems. Utility Model Content

[0004] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0005] This disclosure provides a novel concrete mold for construction joints that eliminates the need for chiseling. It has a reasonable structure, is easy to operate, and can be demolded in sections, avoiding the problem of rough surface damage caused by stress concentration during overall demolding.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A novel concrete mold for construction joints that eliminates the need for chiseling includes a rectangular frame. The top of the frame has several movable holes arranged in a rectangular array. Each movable hole has a cross-shaped support fixed to its inner wall, flush with the top of the frame. Each cross-shaped support consists of four orthogonally distributed support rods, and a drive assembly is rotatably mounted at the center of the top of each cross-shaped support. Each support rod has a transmission component at its top that meshes with the drive assembly. The transmission component extends to the bottom of the cross-shaped support and has a threaded rod threaded inside. The bottom of the threaded rods in the same set of movable holes is connected to the same set of movable plates. The drive assembly, through external force, interacts with the transmission assembly, which in turn drives the threaded rods to move the corresponding movable plates, thus enabling rapid demolding. The movable plates are all adapted to and slide within their corresponding movable holes. The movable plate is flush with the bottom of the rectangular frame, and the bottom of the movable plate is provided with embedded components evenly distributed in a rectangular array. The embedded components form pits in the subsequently poured concrete to replace the rough surface. A set of molds is formed by the cross, drive component, threaded rod, transmission component, movable plate, and embedded components. Each set of movable holes in the rectangular frame is equipped with a set of molds. The drive component is linked to the transmission component, which drives the corresponding threaded rod to move up and down. Each drive component is linked to four transmission components at the same time, which in turn drives the four corresponding threaded rods to move synchronously. This achieves demolding of the movable plate in the mold set in one go, thereby realizing demolding by area according to the movable holes, reducing stress concentration and avoiding damage to the rough surface caused by stress concentration during overall demolding.

[0008] Furthermore, the drive assembly includes a bolt head spindle and a first gear. The bolt head spindle is rotatably positioned at the top center of the cross, and the first gear is fixedly sleeved on the outer side of the bolt head spindle. The first gear is connected to the transmission assembly.

[0009] Furthermore, the transmission assembly includes an internally threaded cylinder and a second gear. Each support rod of the cross is rotatably provided with an internally threaded cylinder at its top. The bottom end of the internally threaded cylinder extends to the bottom of the cross, and a second gear is fixedly sleeved on the top end of the internally threaded cylinder. The second gear meshes with the first gear. The internally threaded cylinder is threaded with a threaded rod inside. The threaded rod extends out of the bottom end of the internally threaded cylinder and connects to the corresponding movable plate. By using an electric wrench to rotate the bolt head spindle in sections, the meshing of the first gear and the second gear drives the internally threaded cylinder to rotate synchronously. The force generated by the rotation of the internal threads of the internally threaded cylinder causes the threaded rod to move upward, thereby driving the movable plate to move upward to remove the film, thus realizing the removal of the film in sections.

[0010] Furthermore, the embedded component includes a pull rod, a cone head, a baffle plate, a cone sleeve, and a spring. The top of the pull rod is fixed to the bottom of the movable plate, and the bottom of each pull rod is fixedly connected to a cone head. The cone head is used to form a pit on the surface of the poured concrete to replace the rough surface. The outer side of each pull rod is fixedly connected to a baffle plate located at the top of the cone head. The outer side of each pull rod is slidably connected to a cone sleeve. The inner cavity of the cone sleeve is adapted to the baffle plate and the cone head. A spring is sleeved on the outer side of the pull rod. The spring is located inside the inner cavity of the cone sleeve. The bottom end of the spring contacts the top side of the baffle plate, and the top end of the spring abuts against the top wall of the inner cavity of the cone sleeve. With the cooperation of the cone sleeve, spring, and baffle plate, when the cone head disengages from the pit it forms, the cone sleeve will press down on the side of the pit under the action of the spring to prevent the pit formed by the cone head from breaking and being damaged during demolding, thus affecting the quality of the rough surface.

[0011] Furthermore, the bottom of the movable plate, except for the area covered by the conical sleeve, is provided with four sharp protrusions arranged in a rectangular array. These four sharp protrusions form a rough surface during concrete pouring, replacing manual roughening and increasing the production efficiency of concrete structures.

[0012] The present disclosure provides a novel concrete mold for construction joints that eliminates the need for chiseling, which can achieve the following technical effects:

[0013] This invention uses a drive assembly linked with a transmission assembly. The transmission assembly drives its corresponding threaded rod to move up and down. Each drive assembly simultaneously links four transmission assemblies, which in turn drive the four corresponding threaded rods to move synchronously. This achieves demolding of the movable plate in the mold assembly in one go, thereby realizing demolding in sections according to the movable holes, reducing stress concentration and avoiding damage to the rough surface caused by stress concentration during one-time overall demolding.

[0026] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

[0027] A novel concrete mold for construction joints that eliminates the need for chiseling includes a rectangular frame 1. The top of the rectangular frame 1 has several movable holes 2 arranged in a rectangular array. The inner walls of each movable hole 2 are fixedly connected to a cross 3 flush with the top of the rectangular frame 1. Each cross 3 consists of four orthogonally distributed support rods, and a drive assembly 4 is rotatably mounted at the center of the top of each cross 3. Each support rod of the cross 3 has a transmission assembly 5 at its top that meshes with the drive assembly 4. The transmission assembly 5 extends to the bottom of the cross 3 and has a threaded rod 6 threaded inside. The bottom ends of the threaded rods 6 within the same set of movable holes 2 are connected to the same set of movable plates 7. The drive assembly 4, through external force, interacts with the transmission assembly 5, causing the transmission assembly 5 to drive the threaded rods 6 and move the corresponding movable plates 7, thus enabling rapid demolding. Each movable plate 7 is adapted to its corresponding movable hole 2. The movable plate 7 is flush with the bottom of the rectangular frame 1, and the bottom of the movable plate 7 is provided with embedded components 8 evenly distributed in a rectangular array. The embedded components 8 form pits in the subsequently poured concrete to replace the rough surface. A set of molds is formed by the cross 3, drive component 4, threaded rod 6, transmission component 5, movable plate 7, and embedded components 8. Each set of movable holes 2 in the rectangular frame 1 is provided with a set of molds. The drive component 4 is linked to the transmission component 5, and the transmission component 5 drives its corresponding threaded rod 6 to rise and fall. Each set of drive components 4 is linked to four sets of transmission components 5 at the same time, which in turn drives the four corresponding threaded rods 6 to move synchronously. Thus, the movable plate 7 in the mold set is demolded at one time, thereby realizing demolding by area according to the movable holes 2, reducing stress concentration and avoiding damage to the rough surface caused by stress concentration during overall demolding.

[0028] The drive assembly 4 includes a bolt head spindle 401 and a first gear 402. The bolt head spindle 401 is rotatably positioned at the top center of the cross 3. The first gear 402 is fixedly sleeved on the outer side of the bolt head spindle 401. The first gear 402 is connected to a transmission assembly 5. The transmission assembly 5 includes an internally threaded cylinder 501 and a second gear 502. An internally threaded cylinder 501 is rotatably mounted on the top of each support rod of the cross 3. The bottom end of the internally threaded cylinder 501 extends to the bottom of the cross 3, and a second gear 502 is fixedly sleeved on the top end of the internally threaded cylinder 501. 2. The second gear 502 meshes with the first gear 402. The internal threaded cylinder 501 is threaded with threaded rods 6. The threaded rods 6 extend out of the bottom of the internal threaded cylinder 501 and are connected to the corresponding movable plates 7. Using an electric wrench, the bolt head spindle 401 is rotated in sections. Since the first gear 402 meshes with the second gear 502, it drives the internal threaded cylinder 501 to rotate synchronously. The force generated by the rotation of the internal threads of the internal threaded cylinder 501 causes the threaded rods 6 to move upward, thereby driving the movable plates 7 to move upward to remove the film, thus realizing the removal of the film in sections.

[0029] The embedded component 8 includes a pull rod 801, a cone head 802, a baffle 803, a cone sleeve 804, and a spring 805. The top end of the pull rod 801 is fixed to the bottom of the movable plate 7. The bottom of each pull rod 801 is fixedly connected to a cone head 802, which is used to form a pit on the surface of the poured concrete to replace the rough surface. The outer side of each pull rod 801 is fixedly connected to a baffle 803 located at the top of the cone head 802. The outer side of each pull rod 801 is slidably connected to a cone sleeve 804. The inner cavity of the cone sleeve 804 is adapted to the baffle 803 and the cone head 802. A spring 805 is sleeved on the outer side of the pull rod 801. The spring 805 is located on the cone sleeve 805. Inside the cavity of 4, the bottom end of the spring 805 contacts the top side of the baffle 803 and the top end of the spring 805 abuts against the top wall of the inner cavity of the cone sleeve 804. With the cooperation of the cone sleeve 804, the spring 805, and the baffle 803, when the cone head 802 disengages from the recess it forms, the cone sleeve 804 will press the side of the recess under the action of the spring 805 to prevent the recess formed by the cone head 802 from breaking and being damaged during demolding, thus affecting the surface quality. The bottom of the movable plate 7, except for the area covered by the cone sleeve 804, is provided with four sharp protrusions 9 arranged in a rectangular array. The four sharp protrusions 9 form a rough surface during concrete pouring, replacing manual roughening and increasing the production efficiency of concrete structures.
