Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated buildings, in particular to a general mold for prefabricated building wall panels. Background Technique

[0002] In response to the needs of social progress and development, the country strongly advocates prefabricated buildings, and precast concrete buildings are the absolute main force in prefabricated buildings. Precast concrete buildings are mainly composed of precast concrete wall panels, floor slabs, composite slabs and other PC components. However, the generality of the existing related technology for producing PC component molds is relatively low. Not only do the molds for wall panels, floor slabs, composite slabs and prestressed slabs require different corresponding designs and productions, and the forms are different; even the molds for wall panels, floor slabs, composite slabs and prestressed slabs of different sizes need to be customized separately, and the molds of different sizes are basically not universal.

[0003] Therefore, the patent with the application number CN202022754413.2 discloses a standardized mold for prefabricated building wall panels. Although the size can be adjusted, it is by adding a plurality of uniformly distributed fixed grooves on the fixed side mold, and according to the size requirements, the movable side mold is cross-connected to different positions of the fixed grooves; however, due to the fixed spacing of the fixed grooves, the adjustable size of the mold of this patent is also fixed, and stepless adjustment cannot be achieved, resulting in a limited adaptation range, and multiple reserved fixed grooves will reduce the strength of the side mold; at the same time, each time when using multiple fixed grooves, only one fixed groove needs to be connected with a fixed hinge, and the other fixed grooves need to be blocked during the pouring process, which is time-consuming and laborious.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0027] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0028] Referring to Figure 1 and Figure 2 , in an embodiment of a general mold for prefabricated building wall panels of the present utility model, the general mold for prefabricated building wall panels includes a bottom plate 1, a first transverse side mold 21, a first longitudinal side mold 31, a second transverse side mold 22, a second longitudinal side mold 32, a first U-shaped frame 41, a second U-shaped frame 42, a third U-shaped frame 43, and a fourth U-shaped frame 44.

[0029] Among them, the first transverse side mold 21, the first longitudinal side mold 31, the second transverse side mold 22, and the second longitudinal side mold 32 are sequentially and slidably connected end to end through the first U-shaped frame 41, the second U-shaped frame 42, the third U-shaped frame 43, and the fourth U-shaped frame 44 respectively. Specifically, both ends of the first U-shaped frame 41 are welded to the bottom plate 1, one end of the first transverse side mold 21 is welded to the first U-shaped frame 41, and the other end of the first transverse side mold 21 is slidably inserted into the fourth U-shaped frame 44; one end of the first longitudinal side mold 31 is slidably inserted into the first U-shaped frame 41, and the other end of the first longitudinal side mold 31 is welded to the second U-shaped frame 42; one end of the second transverse side mold 22 is slidably inserted into the second U-shaped frame 42, and the other end of the second transverse side mold 22 is welded to the third U-shaped frame 43; one end of the second longitudinal side mold 32 is slidably inserted into the third U-shaped frame 43, and the other end of the second longitudinal side mold 32 is welded to the fourth U-shaped frame 44.

[0030] Among them, fasteners 5 are respectively provided on the first U-shaped frame 41, the second U-shaped frame 42, the third U-shaped frame 43, and the fourth U-shaped frame 44; specifically, the fasteners 5 can be set as screws, and the screws penetrate and are threadedly connected to the side walls of the first U-shaped frame 41, the second U-shaped frame 42, the third U-shaped frame 43, or the fourth U-shaped frame 44. Tightening the screws can make the screw rods of the screws abut against the corresponding first transverse side mold 21, first longitudinal side mold 31, second transverse side mold 22, or second longitudinal side mold 32 for fixation.

[0031] During use, the space formed by enclosing the first horizontal side mold 21, the first vertical side mold 31, the second horizontal side mold 22, and the second vertical side mold 32 with the bottom plate 1 is used as the pouring cavity for pouring the wall panel. Move the second horizontal side mold 22 to drive the first vertical side mold 31 to slide relative to the first U-shaped frame 41, and at the same time drive the third U-shaped frame 43 to slide relative to the second vertical side mold 32. Until the distance between the second horizontal side mold 22 and the first horizontal side mold 21 is suitable for the width of the wall panel to be customized, then use the corresponding fasteners 5 to limit the relative sliding of the side mold and the U-shaped frame, achieving the effect of steplessly adjusting the width of the pouring cavity; Move the second vertical side mold 32 to drive the second horizontal side mold 22 to slide relative to the second U-shaped frame 42, and at the same time drive the fourth U-shaped frame 44 to slide relative to the first horizontal side mold 21. Until the distance between the second vertical side mold 32 and the first vertical side mold 31 is suitable for the length of the wall panel to be customized, then use the corresponding fasteners 5 to limit the relative sliding of the side mold and the U-shaped frame, achieving the effect of steplessly adjusting the length of the pouring cavity. Therefore, by the above method, the mold size can be steplessly adjusted to make the pouring cavity suitable for the wall panel to be customized.

[0032] Referring to Figure 3 , the two ends of the first U-shaped frame 41, the second U-shaped frame 42, the third U-shaped frame 43, and the fourth U-shaped frame 44 in this embodiment are flush with the upper surface of the bottom plate 1 and the lower surfaces of the first horizontal side mold 21, the first vertical side mold 31, the second horizontal side mold 22, and the second vertical side mold 32. This not only does not affect the relative sliding of the U-shaped frame and the side mold, but also can reduce the gap between the side mold and the bottom plate 1 to prevent leakage of slurry.

[0033] Continuing to refer to Figure 1 and Figure 2 , in this embodiment, a guiding longitudinal groove 11 extending along the length direction of the first vertical side mold 31 is opened on the bottom plate 1 below the first vertical side mold 31. A first positioning block 111 is welded to one side of the second U-shaped frame 42. The bottom of the first positioning block 111 is located in the guiding longitudinal groove 11, and the two side surfaces of the first positioning block 111 are respectively close to the two side walls of the guiding longitudinal groove 11, so that the guiding longitudinal groove 11 can guide the sliding of the first vertical side mold 31 and prevent its position from shifting.

[0034] Similarly, a guiding transverse groove 12 extending along the length direction of the first horizontal side mold 21 can be opened on the bottom plate 1 outside the first horizontal side mold 21. A second positioning block 121 is welded to one side of the fourth U-shaped frame 44. The bottom of the second positioning block 121 is located in the guiding transverse groove 12, and the two side surfaces of the second positioning block 121 are respectively close to the two side walls of the guiding longitudinal groove 11.

[0035] Referring to Figures 4 - 6, in another embodiment, the general mold for prefabricated building wall panels further includes a first lead screw 61, a first nut 62 and a first motor 63. The first lead screw 61 extends along the length direction of the first horizontal side mold 21; the first nut 62 is welded to the upper surface of the fourth U-shaped frame 44 and coaxially threadedly sleeved on one end of the first lead screw 61; the first motor 63 is fixedly installed on the bottom plate 1 through a bracket, and the output shaft of the first motor 63 is coaxially connected to the other end of the first lead screw 61. By driving the first lead screw 61 to rotate through the first motor 63, the first nut 62 can drive the second longitudinal side mold 32 to slide along the first horizontal side mold 21 under the action of the thread, saving manpower.

[0036] Similarly, a second lead screw 71, a second nut 72 and a second motor 73 can also be provided; the second lead screw 71 extends along the length direction of the first longitudinal side mold 31; the second nut 72 is welded to the upper surface of the second U-shaped frame 42 and coaxially threadedly sleeved on one end of the second lead screw 71; the first motor 63 is fixedly installed on the first U-shaped frame 41, and the output shaft of the first motor 63 is coaxially connected to the other end of the second lead screw 71. By driving the second lead screw 71 to rotate through the second motor 73, the second nut 72 can drive the second horizontal side mold 22 to slide along the first longitudinal side mold 31 under the action of the thread.

[0037] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
