Description

Technical Field

[0001] This utility model relates to the field of prefabricated bay window mold technology, and more specifically to the field of prefabricated bay window mold technology that can be demolded in situ. Background Technology

[0002] The precast bay window inner wall panel protrudes 100mm inward toward the window frame. When the inner mold is demolded, the 100mm wide inward protruding wall panel presses vertically onto the inner mold and the inner mold step surface, making it impossible to lift the inner mold for demolding. The only vertical demolding solution is to lift the component and then knock the inner mold downwards for demolding. In this production method, when the component and the inner mold are lifted as a whole, the inner mold is knocked downwards for demolding. At this time, the gravity generated when the inner mold falls will exert a large hammer force on the mold table surface downwards. The mold table will be greatly damaged and dented under the impact of gravity.

[0003] If the component manufacturing process is set to demold the inner mold in a horizontal inward direction, the 100mm wide inner wall reverse eaves exert vertical downward pressure on the template surface. When the inner mold is retracted, in addition to overcoming the adsorption force between the template and the component on the lower surface of the reverse eaves side, it is also necessary to overcome the vertical pressure of the reverse eaves of the component's inner wall panel on the inner mold panel. Therefore, the inner mold cannot achieve horizontal inward demolding due to the above background reasons.

[0004] In summary, existing prefabricated bay windows suffer from difficulties in demolding the inner mold and are prone to damage to the mold table under the production process without a bottom mold or mold table. Utility Model Content

[0005] The purpose of this utility model is to solve the technical problems of difficult demolding of the inner mold and easy damage of the mold table under the existing prefabricated bay window production process without bottom mold. This utility model provides a prefabricated bay window mold that can be demolded in situ.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] This utility model provides a precast bay window mold that can be demolded in situ, including a square-shaped bottom mold pad block set on the mold table, an outer mold set on the outer side wall of the bottom mold pad block, an inner mold set on the inner side wall of the bottom mold pad block, and a wall panel edge mold set on the top of the outer mold. The bottom mold pad block, the outer mold and the inner mold form a mold cavity. Multiple inner mold suspension support seats of equal height for installing the inner mold are detachably set on the inner side wall of the bottom mold pad block. There is a demolding gap between the inner mold suspension support seats and the mold table surface.

[0008] Specifically, the flatness of the fixed mold table surface must be inspected before production (using a 2m straightedge and feeler gauge for measurement). The mold table surface must be leveled before assembling and installing the mold. After the mold table surface is leveled, the support points of the mold table surface must be evenly stressed, and situations where the support points are suspended should be avoided. Otherwise, the mold table surface may become concave or torsional due to prolonged production of large components.

[0009] Mold assembly sequence: Weld the bottom mold pad block to the mold table surface -- Install the inner mold suspension support on the inner wall of the bottom mold pad block -- Place the inner mold on the inner mold suspension support and fasten it to the bottom mold pad block with bolts -- Hoist the steel cage into the mold cavity -- Assemble the outer mold -- Assemble the wall panel side mold -- Assemble the lifting points and tie rod fixtures.

[0010] Mold dismantling sequence: Mold dismantling is done in reverse order of mold assembly. First, remove the cantilever fixtures, tie rods, and other embedded fixtures---remove the wall panel side molds---remove the connecting bolts between the outer molds---remove the connecting bolts between the inner mold suspension support and the bottom pad---remove the connecting bolts between the inner mold inner side templates---use a rubber mallet to tap the inner side templates downwards in sequence (tapping the key molds first) to slightly loosen the inner side templates from the concrete surface---then use a two-way screw rod to pull the inner side templates downwards to achieve the downward movement of the inner side templates and complete the inner mold demolding action---lift out the component---clean the mold---mold assembly.

[0011] In one embodiment, the bottom mold pad is connected to the mold table surface by spot welding after being marked and positioned. The inner mold is placed on multiple inner mold suspension supports, which are fixed to the inner sidewall of the bottom mold pad by bolts.

[0012] In one embodiment, a channel steel support frame is welded to the bottom of the bottom mold pad, and multiple lower screw connecting lugs are welded on the channel steel support frame. Multiple upper screw connecting lugs, which correspond one-to-one with the multiple lower screw connecting lugs, are provided on the top of the inner mold. A bidirectional screw is hinged between the corresponding lower screw connecting lug and the upper screw connecting lug.

[0013] In one embodiment, the inner mold is rectangular in shape and includes four inner templates with corners. Adjacent inner templates are connected by a linkage mechanism and bolts. The upper screw has four connecting lugs, which are welded to the top of the inner side of the corresponding inner template. The lower screw has four connecting lugs and four bidirectional screws.

[0014] Specifically, the bidirectional lead screw effectively connects the four module plates of the inner mold with the base support channel steel.

[0015] In one embodiment, there is a 70mm demolding gap between the inner mold suspension support and the mold table surface.

[0016] Specifically, during demolding, first remove the connecting bolts between the inner templates of the inner mold, then remove the connecting bolts between the inner mold suspension support and the side of the bottom pad. At this time, there is a 70mm downward displacement space between the inner mold and the mold table surface. Use a rubber mallet to tap the inner mold downwards until the template surface and the concrete surface are slightly loosened. Then rotate the double-sided screw. Under the tension of the double-sided screw and the weight of the inner mold itself, the inner template slides downwards. Each inner template is driven by the linkage mechanism (connecting rod), and the inner mold moves down 70mm to complete the demolding action, realizing the overall in-situ demolding of the inner mold. This process does not require the use of a crane for demolding. At the same time, demolding and assembly do not require lifting the inner mold out, reducing the area occupied in the production site, greatly shortening the operation time of assembling and disassembling the inner mold, and reducing the crane occupancy rate.

[0017] In one embodiment, each inner template includes a panel and multiple stiffening plates welded to the panel in a crisscross pattern to increase the strength of the panel. The panel is 6mm thick, and each stiffening plate is 8mm thick. Both the panel and each stiffening plate are made of Q235 steel plate.

[0018] In one implementation, the linkage mechanism is a pull rod used for limiting the position.

[0019] In one embodiment, the outer mold is rectangular in shape and includes four outer templates. Adjacent outer templates are connected by bolts. Support frames are provided on the outer walls of each outer template, and a height adjustment screw mechanism is provided at the bottom of the support frame. The height adjustment screw mechanism controls the lifting height through a height limiting nut at the top and a lifting nut at the bottom.

[0020] Specifically: The support frame of the outer formwork is equipped with a height adjustment screw mechanism. When assembling the formwork, tighten the height limit nut and the lifting nut to the appropriate position (there should be no misalignment on the upper plane of the adjacent outer formwork). When disassembling the formwork, tighten the lifting nut downwards. Under the action of the eccentric force, the entire outer formwork module tilts downwards. At this time, the outer formwork is separated from the component, and the outer formwork is demolded in place without the need to use a crane to open the outer formwork.

[0021] In one embodiment, the support frame includes a horizontal bar welded to the lower side of the outer wall of the outer template, an inclined tie rod welded to the horizontal bar and the upper side of the outer wall of the outer template, and a height adjustment screw mechanism disposed on the horizontal bar on the side of the horizontal bar away from the outer template.

[0022] In one embodiment, the outer template includes a vertically arranged vertical panel and a lower flange plate welded to the outer wall of the vertical panel near the bottom. The lower flange plate is located below the support, and a 5mm gap is reserved between the bottom of the lower flange plate and the bottom of the vertical panel during welding.

[0023] The beneficial effects of this utility model are as follows:

[0024] 1. This utility model has a reasonable design, which shortens the operation time of mold assembly and disassembly, optimizes mold design, and has the advantages of simple process, more convenient construction and no damage to components.

[0025] 2. When demolding, first remove the connecting bolts between the inner templates of the inner mold, and then remove the connecting bolts between the inner mold suspension support and the side of the bottom pad. At this time, there is a 70mm downward displacement space between the inner mold and the mold table surface. Use a rubber mallet to tap the inner mold downwards until the template surface and the concrete surface are slightly loosened. Then rotate the double-sided screw. Under the action of the tension of the double-sided screw and the weight of the inner mold itself, the inner template slides downwards. Each inner template is driven by the linkage mechanism (connecting rod), and the inner mold moves down 70mm to complete the demolding action. This achieves the whole inner mold in-situ demolding. This process does not require the use of a crane for demolding. At the same time, the inner mold does not need to be lifted out for demolding and demolding assembly, which reduces the area occupied in the production site, greatly shortens the operation time of assembling and disassembling the inner mold, and reduces the crane occupancy rate.

[0026] 3. A height adjustment screw mechanism is set on the support frame of the outer formwork. When assembling the formwork, tighten the height limit nut and the lifting nut to the appropriate position (there should be no misalignment on the upper plane of the adjacent outer formwork). When disassembling the formwork, tighten the lifting nut downwards. Under the action of the eccentric force, the entire outer formwork module tilts downwards. At this time, the outer formwork is separated from the component, and the outer formwork is demolded in place without the need to use a crane to open the outer formwork. Attached Figure Description

[0041] Specifically, the flatness of the fixed mold table surface must be inspected before production (using a 2m straightedge and feeler gauge for measurement). The mold table surface must be leveled before assembling and installing the mold. After the mold table surface is leveled, the support points of the mold table surface must be evenly stressed, and situations where the support points are suspended should be avoided. Otherwise, the mold table surface may become concave or torsional due to prolonged production of large components.

[0042] Mold assembly sequence: Weld bottom mold pad 7 onto the mold table surface -- Install inner mold 3 suspension support 6 on the inner side wall of bottom mold pad 7 -- Place inner mold 3 on inner mold 3 suspension support 6 and fasten it to bottom mold pad 7 with bolts -- Hoist the steel cage into the mold cavity -- Assemble outer mold 1 -- Assemble wall panel side mold 2 -- Assemble lifting points and tie rod fixtures.

[0044] Example 2

[0045] This embodiment is a further optimization based on Embodiment 1, specifically:

[0046] After the bottom mold pad 7 is marked and positioned with the mold table surface, it is connected by spot welding. The inner mold 3 is placed on multiple inner mold 3 suspension supports 6, and the inner mold 3 suspension supports 6 are fixed to the inner side wall of the bottom mold pad 7 by bolts.

[0047] The bottom of the bottom mold pad 7 is welded with a channel steel support frame 8. Multiple lower screw connecting lugs are welded on the channel steel support frame 8. The top of the inner mold 3 is provided with multiple upper screw connecting lugs that correspond one-to-one with the multiple lower screw connecting lugs. A bidirectional screw 5 is hinged between the corresponding lower screw connecting lugs and the upper screw connecting lugs.

[0048] The inner mold 3 is square in shape and includes four inner templates with corners. Adjacent inner templates are connected by a linkage mechanism 4 and bolts. The upper screw has four connecting lugs, which are welded to the top of the inner side of the corresponding inner template. The lower screw has four connecting lugs and four bidirectional screws 5.

[0049] Specifically, the bidirectional lead screw 5 enables the four module plates of the inner mold 3 to be effectively connected to the base support channel steel.

[0050] Example 3

[0051] This embodiment is a further optimization based on embodiment 2, specifically:

[0052] There is a 70mm demolding gap between the inner mold 3 suspension support 6 and the mold table surface.

[0053] Each inner template includes a panel and multiple stiffening plates welded to the panel in a crisscross pattern to increase the panel's strength. The panel is 6mm thick, and each stiffening plate is 8mm thick. Both the panel and each stiffening plate are made of Q235 steel plate.

[0054] Linkage mechanism 4 is a pull rod used for limiting movement.

[0055] Specifically, during demolding, first remove the connecting bolts between the inner templates of the inner mold 3, and then remove the connecting bolts between the inner mold 3 suspension support 6 and the side of the bottom pad. At this time, there is a 70mm drop displacement space between the inner mold 3 and the mold table surface. Use a rubber mallet to tap the inner mold 3 downwards until the template surface and the concrete surface are slightly loosened. Then rotate the double-sided screw 5. Under the tension of the double-sided screw 5 and the weight of the inner mold 3 itself, the inner template slides downwards. Each inner template is driven by the linkage mechanism 4 (connecting rod), and the inner mold 3 moves down 70mm to complete the demolding action of the inner mold 3. This achieves the overall in-situ demolding of the entire inner mold 3. This process does not require the use of a crane for demolding. At the same time, the inner mold 3 does not need to be lifted out for demolding and demolding assembly, which reduces the area occupied in the production site, greatly shortens the operation time of assembling and disassembling the inner mold 3, and reduces the crane occupancy rate.

[0056] Example 4

[0057] This embodiment is a further optimization based on embodiment 3, specifically:

[0058] The outer mold 1 is square in shape and includes four outer templates. The two adjacent outer templates are connected by bolts. A support frame is provided on the outer wall of each outer template. A height adjustment screw mechanism is provided at the bottom of the support frame. The height adjustment screw mechanism controls the lifting height through the height limiting nut at the top and the lifting nut at the bottom.

[0059] Specifically: The support frame of the outer formwork is equipped with a height adjustment screw mechanism. When assembling the formwork, tighten the height limit nut and the lifting nut to the appropriate position (there should be no misalignment on the upper plane of the adjacent outer formwork). When disassembling the formwork, tighten the lifting nut downwards. Under the action of the eccentric force, the entire outer formwork module tilts downwards. At this time, the outer formwork is separated from the component, and the outer formwork is demolded in place without the need to use a crane to open the outer formwork.
