DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Combination Figure 1-Figure 5 As shown, a channel forming mold frame of the utility model comprises a channel body 1 and a frame 2 for a channel forming slipform machine, wherein the channel body 1 is composed of a channel inner concave surface 11, a channel outer wall 12 and a channel top wall 13.

[0038] The inner mold frame 3 is arranged on the frame 2, and its outer side is in contact with the inner concave surface 11 of the channel;

[0039] The connecting member 4 is arranged on the end surface of the inner mold frame 3 and is arranged parallel to the channel top wall 13;

[0040] The outer mold frame 5 is arranged on the connecting member 4 and the number is two, wherein the opposite surfaces of the two outer mold frames 5 are in contact with the channel outer wall 12 respectively, and the connecting member 4 is used to adjust the distance between the outer mold frame 5 and the inner mold frame 3 to realize the molding of channel walls of various thicknesses;

[0041] The adjusting member 6 is arranged on the frame 2 and is perpendicular to the channel top wall 13;

[0042] The forming plate 7 is disposed on the adjusting member 6 , and its vertical height can be adjusted by the adjusting member 6 to achieve forming of the channel top wall 13 of various heights.

[0043] The channel forming mold frame is mainly composed of a channel body 1 and a frame 2. The channel body 1 is further subdivided into a channel inner concave surface 11, a channel outer wall 12 and a channel top wall 13. Its core components include an inner mold frame 3, a connector 4, an outer mold frame 5, an adjustment member 6 and a forming plate 7. The inner mold frame 3 is firmly arranged on the frame 2, and its outer side is tightly fitted to the channel inner concave surface 11, serving as a supporting template for the internal shape of the channel. The connector 4 is cleverly installed on the end face of the inner mold frame 3 and remains parallel to the channel top wall 13. This design enables the connector 4 to serve as a bridge for adjusting the distance between the outer mold frame 5 and the inner mold frame 3. By adjusting the connector 4, the distance between the two outer mold frames 5 and the inner mold frame 3 can be flexibly changed, thereby achieving precise control of the channel wall thickness to meet different thickness requirements.

The introduction of this component makes it possible to adjust the height of the forming plate 7. The forming plate 7 is installed on the adjusting member 6. By operating the adjusting member 6, the construction personnel can easily adjust the vertical height of the forming plate 7, thereby realizing precise control of the height of the channel top wall 13 and meeting diverse design needs. In summary, the channel forming mold frame realizes all-round and precise control of the channel shape and size through the synergistic effect of the inner mold frame 3, the connecting member 4, the outer mold frame 5, the adjusting member 6 and the forming plate 7. This design not only improves the flexibility and adaptability of the construction, but also ensures the accuracy and stability of the channel forming, and effectively overcomes the many defects of the traditional molds.

[0044] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 5 As shown; the connecting member 4 includes:

[0045] The fixing parts 41 are welded to the end surface of the inner mold frame 3, and the number of the fixing parts 41 is two and they are respectively arranged on the two side ends of the inner mold frame 3;

[0046] A first threaded column 42, one end of which is fixedly mounted on the end of the outer mold frame 5, and the other end of which penetrates and extends to the other side surface of the fixing member 41; and

[0047] The first hand-tightening piece 43 is threadedly connected to the outer side of the first threaded column 42, and its number and distribution position are adapted to the first threaded column 42. The connecting piece 4 is a key component for adjusting the distance between the outer mold frame 5 and the inner mold frame 3. Its internal structure includes a fixing piece 41, a first threaded column 42 and a first hand-tightening piece 43. First, the fixing piece 41 is firmly welded to the end face of the inner mold frame 3, and there are two fixing pieces 41, which are respectively arranged on the two side ends of the inner mold frame 3 to ensure the stability and symmetry of the connection. The fixing piece 41 serves as a support and positioning point, providing a basis for subsequent adjustments. Then, one end of the first threaded column 42 is fixedly installed on the end of the outer mold frame 5. This design The design enables the outer formwork frame 5 to be connected to the fixing piece 41 on the inner formwork frame 3 through the first threaded column 42, and the other end of the first threaded column 42 penetrates and extends to the other side surface of the fixing piece 41. This extended portion becomes the basis of the threaded connection. Finally, the first hand screw 43 is designed to be connected to the outer thread of the first threaded column 42, and its number and distribution position are adapted to the first threaded column 42. By rotating the first hand screw 43, the construction personnel can move forward and backward along the thread track of the first threaded column 42, thereby driving the outer formwork frame 5 to move inward or outward, thereby changing the distance between the outer formwork frame 5 and the inner formwork frame 3, and realizing precise adjustment of the channel wall thickness.

[0048] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 5As shown; the number of first threaded columns 42 is four, which are equally divided into two groups, and each outer mold frame 5 is provided with two first threaded columns 42, wherein the fixing piece 41 is also processed with a first movable hole 8 adapted to the first threaded column 42, and the number and distribution position of the first movable holes 8 correspond to the first threaded columns 42, and the first threaded column 42 can be laterally displaced on the inner side of the first movable hole 8, and is fixed to a certain position on the fixing piece 41 by a first hand-tightening piece 43. Firstly, the number of first threaded columns 42 is set to four, and is equally divided into two groups, with two in each group, which are respectively installed on the ends of the two outer mold frames 5. Such a layout ensures that the outer mold frame 5 can maintain balance and stability during the adjustment process, and avoids displacement or deformation caused by uneven force. Then, the fixing piece 41 is processed with a first movable hole 8 adapted to the first threaded column 42 Holes 8, the number and distribution positions of these first movable holes 8 correspond one-to-one with the first threaded columns 42, providing space for the first threaded columns 42 to move laterally. This design allows the first threaded columns 42 to move laterally within a certain range on the inner side of the first movable holes 8 without the need for complete disassembly, thereby further increasing the flexibility and convenience of adjustment. During the adjustment process, the construction personnel first loosen the fixation of the first threaded columns 42 by rotating the first hand-tightening piece 43, and then use the lateral displacement ability of the first threaded column 42 in the first movable hole 8 to move the outer formwork 5 to the desired position. Once the outer formwork 5 reaches the predetermined position, the first hand-tightening piece 43 is rotated again to fix the first threaded column 42 to the fixing piece 41 through a threaded connection, thereby achieving precise control of the distance between the outer formwork 5 and the inner formwork 3.

[0049] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 5As shown; the inner side of the first hand screw 43 is provided with an internal thread matched with the external thread of the first threaded column 42, and a rubber pad is provided on the end of the first hand screw 43 close to the fixing member 41. The first hand screw 43 is a key component for connecting and adjusting the distance between the outer mold frame 5 and the inner mold frame 3. The inner side is designed with an internal thread matched with the external thread of the first threaded column 42, which is not directly marked in the figure, but it can be understood from the description that this thread design allows the first hand screw 43 to move up and down along the thread trajectory of the first threaded column 42 through a rotation action, thereby achieving the tightening or loosening of the first threaded column 42. In further optimized design, a rubber pad is specially provided on the end of the first hand screw 43 close to the fixing member 41, which is not directly marked in the figure, but its position can be imagined based on the description. The introduction of the rubber pad not only increases the first hand screw 43 The contact area with the fixing part 41 improves the stability of the connection, and through its elasticity and buffering effect, effectively reduces the potential damage to the formwork structure caused by vibration and impact generated during the tightening process. When it is necessary to adjust the distance between the outer formwork 5 and the inner formwork 3, the construction personnel first rotate the first hand-tightening piece 43 to move it downward along the first threaded column 42 until the tightening effect on the first threaded column 42 is completely released. Then, the outer formwork 5 can be guided by the first threaded column 42 and laterally displaced in the first movable hole 8 of the fixing part 41 until the desired adjustment position is reached. Finally, the first hand-tightening piece 43 is rotated again to move it upward along the first threaded column 42, and the first threaded column 42 is firmly fixed to the fixing part 41 through the pressing effect of the rubber pad, thereby completing the precise adjustment of the thickness of the entire channel wall.

[0050] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 5 As shown; the adjusting member 6 comprises:

[0051] A second threaded column 61 is disposed through the frame 2 and one end of which is connected to the forming plate 7; and

[0052] The second hand screw 62 is threadedly connected to the outer side of the second threaded column 61, wherein the second hand screw 62 and the second threaded column 61 are used to fix the forming plate 7 to a certain height to form the channel top wall 13 of various heights. The adjusting member 6 is a key component for controlling the vertical height of the forming plate 7, and its design is ingenious and practical. Specifically, the adjusting member 6 is mainly composed of the second threaded column 61 and the second hand screw 62. The second threaded column 61 is penetrated and arranged on the frame 2, and one end thereof is interconnected with the forming plate 7 to form a stable supporting structure. This design ensures that the forming plate 7 can adjust its vertical height as the second threaded column 61 moves up and down. The height of the channel top wall 13 can be precisely controlled, and the second hand screw 62 is designed to be threadedly connected to the outside of the second threaded column 61. The construction personnel can move up and down along the thread track of the second threaded column 61 by rotating the second hand screw 62. When the height of the forming plate 7 needs to be adjusted, it is only necessary to rotate the second hand screw 62 to move it up or down along the second threaded column 61, thereby driving the forming plate 7 to make corresponding height adjustments. Once the forming plate 7 reaches the predetermined height position, the second hand screw 62 is rotated again to fasten it to the second threaded column 61, so as to ensure the stability and accuracy of the forming plate 7.

[0053] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 5As shown; the number of second threaded columns 61 and second hand screws 62 is four, and each forming plate 7 is provided with two second threaded columns 61 and second hand screws 62. The four second threaded columns 61 and second hand screws 62 are symmetrically distributed according to the center of the frame 2. In order to ensure the stability and accuracy of the forming plate 7 during the height adjustment process, the dependent claim specifically stipulates the number and distribution of the second threaded columns 61 and second hand screws 62. Specifically, the number of second threaded columns 61 and second hand screws 62 is four, and each forming plate 7 is provided with two sets of such components, totaling four sets. The layout of these four sets of components on the forming plate 7 is not random, but is symmetrically distributed according to the center of the frame 2. This symmetrical layout is not only beautiful, but more importantly, it can ensure that the forming plate 7 is When subjected to external force, it can evenly disperse stress, thereby maintaining its stability and balance. The second threaded column 61 in each set of components passes through the frame 2 and is firmly connected to the forming plate 7, serving as the main structure for supporting and adjusting the height, and the second hand screw 62 is threadedly connected to the outer side of the second threaded column 61. By rotating the second hand screw 62, it can move up and down along the thread track of the second threaded column 61, thereby achieving precise adjustment of the height of the forming plate 7. Since the four sets of components are symmetrically distributed, when adjusting the height of the forming plate 7, the construction personnel can operate the four groups of components at the same time, or selectively adjust several groups of components according to actual needs to achieve the expected adjustment effect. This design not only improves the efficiency of the adjustment, but also ensures the stability and safety of the forming plate 7 during the adjustment process.

[0054] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 5 As shown; the frame 2 is processed with second movable holes 9 whose number and distribution positions are compatible with the second threaded columns 61, and the second threaded columns 61 can be laterally displaced in the second movable holes 9. In order to further improve the adjustment function of the channel forming mold frame, the frame 2 is specially processed with second movable holes 9 whose number and distribution positions are compatible with the second threaded columns 61. These second movable holes 9 are not only channels for the second threaded columns 61 to pass through, but also the key to their lateral displacement. Specifically, when it is necessary to adjust the position of the forming plate 7 in the horizontal direction or make fine adjustments to adapt to channels of different widths, the second threaded columns 61 can be The second threaded column 61 can be laterally displaced in the second movable hole 9. This design makes the connection between the second threaded column 61 and the frame 2 no longer limited to a fixed point, but can move freely within a certain range, thereby greatly increasing the flexibility and accuracy of adjustment. It is worth noting that although the second threaded column 61 can be laterally displaced in the second movable hole 9, its threaded connection with the second hand screw 62 still maintains a stable tightening effect, which means that during the adjustment process, the height of the forming plate 7 can still be accurately controlled by rotating the second hand screw 62, and the lateral displacement provides additional degrees of freedom to adapt to different construction requirements.

[0055] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 5 As shown; a threaded hole is provided at one end of the forming plate 7 close to the second threaded column 61, and the second threaded column 61 is threadedly connected to the inner side of the threaded hole. In order to achieve stability and accuracy of the forming plate 7 during height adjustment, the dependent claim specifically stipulates that a threaded hole should be provided at one end of the forming plate 7 close to the second threaded column 61. This design enables the second threaded column 61 to be directly threadedly connected to the inner side of the threaded hole, thereby forming a stable mechanical connection. When the height of the forming plate 7 needs to be adjusted, the construction personnel can rotate the second hand screw 62. Since the second hand screw 62 and the second threaded column 61 are also threadedly connected, Therefore, the second threaded column 61 will move up and down along the threaded trajectory. Since one end of the second threaded column 61 has been firmly threaded in the threaded hole of the forming plate 7, the forming plate 7 will also rise or fall with the movement of the second threaded column 61, thereby achieving precise adjustment of the height. This threaded connection design not only ensures the stability of the forming plate 7 during the adjustment process, avoids construction problems caused by loosening or falling off, but also makes the adjustment process simple and quick. At the same time, due to the precision of the threaded connection, the height adjustment of the forming plate 7 can be very precise, meeting the construction requirements of different channel top wall 13 heights.

[0056] The specific working principle of a channel forming mold frame of the utility model is as follows:

[0057] The channel forming mold frame realizes accurate forming of the channel body 1 through the coordinated work of various precisely designed components. The mold frame is mainly supported by a frame 2, on which an inner mold frame 3, a connecting member 4, an outer mold frame 5, an adjusting member 6 and a forming plate 7 are installed.

[0058] First, the inner mold frame 3 is arranged on the frame 2, and its outer side is in close contact with the inner concave surface 11 of the channel, which serves as the basis for forming the internal shape of the channel. The connecting piece 4 is fixed on the end face of the inner mold frame 3, including a fixing piece 41, a first threaded column 42 and a first hand-tightening piece 43. Each outer mold frame 5 is connected to the fixing piece 41 through two first threaded columns 42. The first threaded column 42 passes through the first movable hole 8 on the fixing piece 41 and can be displaced laterally on its inner side. By rotating the first hand-tightening piece 43 and utilizing its threaded connection with the first threaded column 42, the distance between the outer mold frame 5 and the inner mold frame 3 can be adjusted, thereby controlling the thickness of the formed channel wall. The end of the first hand-tightening piece 43 is The rubber pad also provides additional cushioning and sealing effects. The adjusting member 6 is responsible for adjusting the vertical height of the forming plate 7 to form channel top walls 13 of different heights. Each forming plate 7 is provided with two second threaded columns 61 and second hand screws 62, totaling four groups, which are symmetrically distributed around the center of the frame 2. The second threaded column 61 passes through the second movable hole 9 on the frame 2 and is connected to the threaded hole of the forming plate 7, so that it can be laterally displaced in the second movable hole 9 to adapt to different width requirements. By rotating the second hand screw 62 and utilizing its threaded connection with the second threaded column 61, the height of the forming plate 7 can be accurately adjusted, thereby achieving control of the height of the channel top wall 13.

[0059] In summary, the channel forming mold frame adjusts the channel wall thickness through the coordinated work of the inner mold frame 3 and the outer mold frame 5, and accurately controls the height of the channel top wall 13 through the cooperation of the adjusting member 6 and the forming plate 7. The entire mold frame structure is reasonably designed and flexible to adjust, and can meet the forming requirements of channels of different specifications.
