Description

Technical Field

[0001] This utility model relates to the field of building mold technology, and in particular to a locking component and a prefabricated house forming mold. Background Technology

[0002] Precast houses, being prefabricated in a factory and requiring only on-site assembly, have seen rapid development in recent years due to their significantly shorter construction cycle compared to traditional buildings. Precast houses are formed by pouring concrete into precast molds, which typically include an inner mold, a bottom mold, and an outer mold. These molds, together with the bottom mold, form a ring-shaped casting cavity. The outer mold consists of four outer templates located around the bottom mold, which can slide along their own thickness for easy demolding.

[0003] In related technologies, limiting hooks are set between two adjacent outer formworks to prevent them from moving away from each other. However, the limiting hooks are difficult to make the two adjacent outer formworks fit tightly together on the side that is close to each other. There is a gap between the two adjacent outer formworks on the side that is close to each other, resulting in poor sealing and easy leakage of concrete, which leads to poor casting and forming effect of precast houses. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a locking component that enables two adjacent outer templates to fit tightly together on their closest sides, thereby improving sealing performance, preventing concrete leakage, and resulting in better casting and forming of the precast building.

[0005] This utility model also proposes a prefabricated house forming mold.

[0006] According to a first aspect of the present invention, a locking assembly is used for the outer mold of a prefabricated house forming mold. The outer mold includes four outer templates arranged in a rectangular pattern. The locking assembly includes a first locking member and a second locking member. The first locking member includes a hinge seat and a locking portion. The hinge seat is located on one of the adjacent sides of two outer templates. One end of the locking portion is hinged to the hinge seat, and the end of the locking portion away from the hinge seat forms a locking slope. The second locking member includes a limiting portion and a lifting portion. The limiting portion and the lifting portion are located on the adjacent sides of two outer templates. The other of the outer templates is located on one side of the other and arranged vertically. The lifting part can extend and retract vertically. The locking part can rotate to a locking state where the locking ramp abuts against the side of the limiting part away from the hinge seat. When the locking part is in the locking state, the locking ramp extends upward in a direction close to the hinge seat, and the lifting part can extend to abut against the top of the locking part. Alternatively, the locking ramp extends downward in a direction close to the hinge seat, and the lifting part can extend to abut against the bottom of the locking part.

[0007] The locking assembly according to the embodiments of the present utility model has at least the following beneficial effects: In this application, after the four outer formworks slide to the pouring position, the locking part is rotated to the locked state, and the locking ramp abuts against the side of the limiting part away from the hinge seat. Then, the lifting part extends so that it abuts against the locking part. Since the locking part, when locked, extends upward along the direction close to the hinge seat, and the lifting part can extend to abut against the top of the locking part, or extends downward along the direction close to the hinge seat, and the lifting part can extend to abut against the bottom of the locking part, when the lifting part extends and squeezes the locking part, the locking ramp of the locking part will squeeze the side of the limiting part away from the hinge seat, thereby causing the adjacent two outer formworks to move closer together to fit tightly, resulting in better sealing and less concrete leakage, thus improving the pouring and forming effect of the precast house.

[0008] According to some embodiments of the present invention, a locking groove is provided on the side of the locking part away from the hinge seat, and the side wall of the locking groove away from the hinge seat forms the locking slope.

[0011] According to some embodiments of the present invention, when the locking part is in the locked state, the extension direction of the locking part forms a 45° angle with the thickness direction of the two adjacent outer templates, and the locking inclined surface and the hinge seat are respectively located at both ends of the extension direction of the locking part.

[0012] According to some embodiments of the present invention, the hinge axis of the locking part extends horizontally and is perpendicular to the extension direction of the locking part; and / or, the lifting part is configured as a jack.

[0025] The following is for reference. Figures 1 to 6 This invention describes a locking assembly and a prefabricated house forming mold according to embodiments of the present invention.

[0026] like Figures 1 to 3As shown, the locking assembly 100 according to the first aspect of the present invention is used for the outer mold 500 of the prefabricated house forming mold. The outer mold 500 includes four outer templates 510 arranged in a rectangular shape. For example, the prefabricated house forming mold may include a mounting frame 200, an inner mold 400, an outer mold 500, and a bottom mold 300, etc. The bottom mold 300 is disposed on the mounting frame 200 and has a rectangular frame structure. The inner mold 400 is disposed on the mounting frame 200 and may include four inner templates 410 located on the inner side of the bottom mold 300. The four outer templates 510 of the outer mold 500 are disposed on the mounting frame 200 and located on the outer side of the bottom mold 300, respectively. The outer mold 500 can slide along its own thickness direction.

[0027] refer to Figure 2 and Figure 3 As shown, the locking assembly 100 includes a first locking member 110 and a second locking member 120. The first locking member 110 includes a hinge seat 111 and a locking part 112. The hinge seat 111 is located on one of the adjacent outer templates 510 on the side closest to each other. One end of the locking part 112 is hinged to the hinge seat 111. The end of the locking part 112 away from the hinge seat 111 forms a locking slope 113. The second locking member 120 includes a limiting part 121 and a lifting part 122. The limiting part 121 and the lifting part 122 are located on the other of the adjacent outer templates 510 on the side closest to each other and are arranged vertically. The lifting part 122 can extend and retract vertically. That is, in the two adjacent outer templates 510, the first outer template 510 is provided with a first locking member 110 on the side closer to the second outer template 510, and the second outer template 510 is provided with a second locking member 120 on the side closer to the first outer template 510.

[0028] The locking part 112 can be rotated to a locking state where the locking ramp 113 abuts against the side of the limiting part 121 away from the hinge seat 111. When the locking part 112 is in the locking state, the locking ramp 113 extends upward in a direction close to the hinge seat 111, and the lifting part 122 can extend to abut against the top of the locking part 112. Alternatively, the locking ramp 113 extends downward in a direction close to the hinge seat 111, and the lifting part 122 can extend to abut against the bottom of the locking part 112.

[0029] In this application, after the four outer templates 510 are slid to the pouring position, the locking part 112 is rotated to the locking state, and the locking inclined surface 113 abuts against the side of the limiting part 121 away from the hinge seat 111. Then the lifting part 122 is extended so that the lifting part 122 abuts against the locking part 112. When the locking part 112 is in the locked state, the locking ramp 113 extends upward along the direction close to the hinge seat 111, and the lifting part 122 can extend to abut the top of the locking part 112. Alternatively, the locking ramp 113 extends downward along the direction close to the hinge seat 111, and the lifting part 122 can extend to abut the bottom of the locking part 112. Thus, when the lifting part 122 extends and presses the locking part 112, the locking ramp 113 of the locking part 112 will press the side of the limiting part 121 away from the hinge seat 111, thereby causing the adjacent two outer templates 510 to move closer together to fit tightly, resulting in better sealing and less concrete leakage, thus improving the casting and forming effect of the precast house.

[0030] refer to Figure 2 and Figure 3 As shown, in some embodiments of this application, a locking groove 114 is provided on the side of the locking part 112 away from the hinge seat 111, and a locking slope 113 is formed on the side wall of the locking groove 114 away from the hinge seat 111. In this embodiment, the locking groove 114 is provided to improve the locking effect of the locking assembly 100.

[0031] refer to Figure 3 As shown, in some embodiments of this application, the lifting portion 122 is located above the limiting portion 121. When the locking portion 112 is in the locked state, the locking groove 114 is located at the bottom end of the locking portion 112, and the lifting portion 122 can extend to abut against the top end of the locking portion 112. For example, when the locking portion 112 is in the locked state, the bottom end of the locking groove 114 can be provided through, and the locking ramp 113 can extend upwards at an angle close to the hinge seat 111.

[0032] When the lifting part 122 extends and presses down on the locking part 112, the distance between the locking inclined surface 113 and the side of the limiting part 121 away from the hinge seat 111 gradually decreases, thereby driving the two adjacent outer templates 510 to move closer together until they fit tightly.

[0033] It should be noted that in some other embodiments of this application, the lifting part 122 may be located below the limiting part 121, and when the locking part 112 is in the locked state, the locking groove 114 is located at the top of the locking part 112, and the lifting part 122 can extend to abut against the bottom of the locking part 112.

[0034] refer to Figure 2 and Figure 3As shown, in some embodiments of this application, when the locking part 112 is in a locked state, the extension direction of the locking part 112 forms a 45° angle with the thickness direction of the two adjacent outer templates 510, and the locking inclined surface 113 and the hinge seat 111 are located at both ends of the extension direction of the locking part 112.

[0035] In this embodiment, the arrangement makes the two adjacent outer templates 510 closer together on the side, resulting in a better seal and less leakage of concrete, thus improving the casting and forming effect of the precast house.

[0036] refer to Figure 2 and Figure 3 As shown, in some embodiments of this application, the hinge axis of the locking part 112 extends horizontally and is perpendicular to the extension direction of the locking part 112. In this embodiment, this arrangement makes it easier to rotate the locking part 112 so that its extension direction forms a 45° angle with the thickness direction of the two adjacent outer templates 510, thereby improving the locking effect.

[0037] In some embodiments of this application, the lifting part 122 is configured as a jack. The jack can be operated manually, without the need for a hydraulic or electrical system, which not only reduces costs but also makes it more convenient to use. Furthermore, it is suitable for work environments where hydraulic and electrical systems are not installed.

[0038] It should be noted that the lifting part 122 can also be a lifting cylinder or an electric push rod, etc., which will not be elaborated here.

[0039] According to the prefabricated house forming mold of the second aspect embodiment of the present utility model, refer to Figures 1 to 6 As shown, the system includes a mounting frame 200, a bottom mold 300, an inner mold 400, an outer mold 500, and multiple locking components 100 as described in the first aspect embodiment. The bottom mold 300 is mounted on the mounting frame 200 and may have a rectangular frame structure. The inner mold 400 includes four inner templates 410, which are mounted on the mounting frame 200 and located on the inner sides of the bottom mold 300. The outer mold 500 includes four outer templates 510, which are mounted on the mounting frame 200 and located on the outer sides of the bottom mold 300. The outer templates 510 can slide along their own thickness direction. For example, the mounting frame 200 may be provided with slide rails 220 on all four sides, and the outer templates 510 are slidably mounted on the corresponding slide rails 220. A locking component 100 is provided between the adjacent sides of each pair of adjacent outer templates 510.

[0040] In this embodiment, the precast house forming mold, by adopting the locking component 100 of the first aspect of the present invention, can make the two adjacent outer templates 510 fit tightly on the side that is close to each other, thereby making the sealing better and the concrete less likely to leak out, thus making the precast house casting and forming effect better.

[0041] Since the prefabricated house forming mold can adopt all the technical solutions of the locking component 100 of the first aspect embodiment, it has at least all the beneficial effects brought about by the technical solutions of the first aspect embodiment. These additional beneficial effects will not be repeated here.

[0042] refer to Figures 4 to 6 As shown, in some embodiments of this application, the inner template 410 is slidably connected to the mounting frame 200. The sliding direction of the inner template 410 is set as follows: the inner template 410 can slide from top to bottom along the direction away from its outer template 510, and can slide from bottom to top along the direction close to its outer template 510. The prefabricated house forming mold also includes multiple driving components 600. Each inner template 410 and the mounting frame 200 are provided with a driving component 600, which is used to drive the inner template 410 to slide.

[0043] In this embodiment, when the driving component 600 drives the inner template 410 to slide from bottom to top along the direction close to its outer side of the outer template 510, the inner template 410 can be quickly moved to the pouring position. When the driving component 600 drives the inner template 410 to slide from top to bottom along the direction away from its outer side of the outer template 510, the inner template 410 can be quickly demolded. Moreover, the inner template 410 slides downward at an angle, and the demolding can also be made easier by utilizing the gravity of the inner template 410 itself.

[0044] refer to Figures 4 to 6 As shown, in some embodiments of this application, the drive assembly 600 includes a first connecting portion 610, a guide portion 620, a sliding portion 630, a hinge rod 640, and a drive screw 650.

[0045] The first connecting part 610 is located on the inner sidewall of the inner template 410. The guide part 620 is located on the mounting bracket 200 and below the bottom mold 300. The guide part 620 can extend along the thickness direction of the adjacent inner template 410, pass through the bottom mold 300 and extend to the outside of the bottom mold 300. The outer end of the guide part 620 can be provided with a threaded hole, and the inner end of the guide part 620 can be provided with a groove 621. The groove 621 can extend along the extending direction of the guide part 620. The sliding part 630 is slidably installed in the groove 621 of the guide part 620 along the thickness direction of the adjacent inner template 410. The sliding part 630 is located below the inner side of the adjacent inner template 410. The sliding part 630 can be provided with a pulley and slides through the pulley to make the sliding smoother. The two ends of the hinge rod 640 are respectively hinged to the guide part 620 and the first connecting part 610. The drive screw 650 is threaded to the threaded hole of the guide part 620 and extends along the sliding direction of the sliding part 630. The inner end of the drive screw 650 is connected to the sliding part 630, and the outer end of the drive screw 650 extends out of the outer side of the bottom mold 300. The outer end of the drive screw 650 can be connected to a handle 660.

[0046] In this embodiment, the exposed handle 660 drives the screw 650 to rotate. The screw 650 is threadedly connected to the threaded hole of the guide part 620, and can move along the thickness direction of the adjacent inner template 410. This causes the sliding part 630 to slide along the thickness direction of the adjacent inner template 410. The sliding part 630 can drive the corresponding inner template 410 to slide through the hinge rod 640 between it and the first connecting part 610 on the inner sidewall of the inner template 410. This allows the inner template 410 to slide to the pouring position or to achieve demolding. The operation is simple and convenient, saving time and effort.

[0047] It should be noted that the drive component 600 can also be other structures. For example, the inner template 410 can be slid by the extension and retraction of the hydraulic cylinder, which will not be elaborated here.

[0048] refer to Figures 4 to 6 As shown, in some embodiments of this application, the inner template 410 is provided with a plurality of second connecting portions 420 on its inner side, and the mounting bracket 200 is provided with a plurality of support members 210. The second connecting portion 420 is provided with a connecting groove 421, which extends obliquely from top to bottom along the direction away from the adjacent inner template 410. The support member 210 is provided with a connecting shaft 211, which is parallel to the surface of the adjacent inner template 410 in the thickness direction and extends in the horizontal direction. The connecting shaft 211 passes through the connecting groove 421 and can slide relative to the second connecting portion 420 along the extension direction of the connecting groove 421.

[0049] In this embodiment, the cooperation between the connecting shaft 211 of the support member 210 and the connecting groove 421 of the second connecting part 420 not only supports the inner mold 400, but also enables the inner template 410 to slide precisely to the pouring position or to be demolded along the inclined direction.

[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
