Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building component production technology, specifically, it relates to prefabricated bay window molds. Background Technology

[0002] In prefabricated buildings, precast bay windows are widely used because they reduce on-site construction and improve building quality. With the rapid development of the construction industry, the demand for precast concrete components is increasing, and the requirements are becoming more stringent. As a core component of prefabricated buildings, precast bay windows must meet the following requirements: Structural complexity: The upper floating panel (sunshade baffle) and the lower floating panel (window sill) form an intermediate cavity with a depth of 300-800mm; Decorative requirements: Exposed surfaces often have decorative layers such as carvings and textures (thickness 5-20mm), and must be free from damage during demolding; Precision standard: The flatness error of the installation interface is ≤1mm.

[0003] However, traditional precast bay window molds typically employ a fixed middle mold design, which has the following drawbacks: Demolding difficulties: The bay window structure includes a cavity formed by the upper and lower bay panels. The middle mold part of the mold is difficult to remove due to the narrow cavity, and often requires forceful demolding, resulting in damage to the edge of the component. Insufficient precision: Misalignment is prone to occur at the joint between the middle mold and the side mold, resulting in poor flatness of the bay window base plate after pouring (error > 3mm), which affects the installation quality; Inefficient: Demolding requires multiple people to work together and external lifting equipment, and a single demolding takes up to 30 minutes.

[0004] Based on the above technical issues, it is necessary to develop a prefabricated bay window mold that can achieve rapid and non-destructive demolding while ensuring production efficiency and the flatness and precision of the molded surface. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated bay window mold, which aims to solve the problems of difficult demolding, insufficient molding accuracy and low production efficiency of traditional prefabricated bay window molds.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A precast bay window mold, characterized in that it includes a bay window inner mold middle mold, two bay window inner mold side molds symmetrically arranged on both sides of the bay window inner mold middle mold, and a number of bay window outer molds, wherein the bay window inner mold middle mold, the two bay window inner mold side molds and the number of bay window outer molds enclose a concrete pouring cavity. The inner mold of the bay window includes a horizontally arranged upper forming panel and a bottom plate. A lifting mechanism is installed between the upper forming panel and the bottom plate, and the lifting mechanism is used to drive the upper forming panel to move up and down. The bay window inner mold side mold includes a side mold upper forming panel, a side mold side forming panel, and a side mold bottom plate; the side mold upper forming panel is horizontally flush with and adjacent to the middle mold upper forming panel, and the side mold bottom plate is horizontally flush with the middle mold bottom plate; the side mold upper forming panel and the side mold bottom plate are aligned with each other at the ends away from the bay window inner mold middle mold, and the side mold side forming panel is vertically installed at the ends of the side mold upper forming panel and the side mold bottom plate away from the bay window inner mold middle mold.

[0007] As a further preferred embodiment of this technical solution, the inner mold of the bay window further includes an upper support channel steel, a lower support channel steel, a support column, and a support angle steel; the upper forming panel of the inner mold is fixedly installed on the upper surface of the upper support channel steel, and the two sides of the upper forming panel of the inner mold extend beyond the support area of ​​the upper support channel steel; the lower support channel steel is fixedly connected to the bottom plate of the inner mold through a vertically arranged support column; the support angle steel is fixedly connected below the overhang of the upper forming panel of the inner mold.

[0008] As a further preferred embodiment of this technical solution, the lifting mechanism includes a top screw and a screw bolt that is threadedly engaged with the top screw; the top screw vertically penetrates the lower support channel steel, and the top screw and the lower support channel steel are in sliding engagement; the top of the top screw is fixedly connected to the upper support channel steel, and the top screw moves up and down through the screw bolt.

[0009] As a further preferred embodiment of this technical solution, the lead screw includes a fixing bolt, an upward drive bolt, and a downward drive bolt; the fixing bolt is fixedly connected to the upper support channel steel, and the upper end of the top screw passes through the fixing bolt and is fixedly connected to the upper support channel steel; the upward drive bolt and the downward drive bolt are respectively installed above and below the lower support channel steel, and respectively abut against the upper and lower surfaces of the lower support channel steel.

[0010] As a further preferred embodiment of this technical solution, the inner mold of the bay window also includes a limiting post, which is vertically installed on the bottom plate of the inner mold, and the height of the limiting post is greater than the height of the lower support channel steel.

[0011] As a further preferred embodiment of this technical solution, the inner mold side mold of the bay window further includes a connecting plate. The connecting plate is vertically installed below the forming panel on the side mold, and one end of the forming panel on the side mold, near the middle mold of the inner mold of the bay window, extends out of the connection position of the connecting plate. The overhang of the forming panel on the side mold is adjacent to the overhang of the forming panel on the middle mold and is supported by the supporting angle steel. One side of the supporting angle steel is fixedly connected to the lower surface of the overhang of the forming panel on the middle mold, and the other side is detachably connected to the connecting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Completely solves the problem of demolding damage: Traditional molds use fixed inner molds for bay windows that cannot detach from the narrow cavity. Forced demolding inevitably scratches the concrete surface and can easily cause irreversible damage to the decorative surfaces that require further processing. However, this utility model sets the inner mold of the bay window to be vertically liftable. During the demolding stage, the inner mold of the bay window can actively descend, thereby freeing up a certain central cavity area. This allows the side molds of the inner mold of the bay window to be moved horizontally without contact, completely avoiding physical friction with the concrete component. This fundamentally eliminates the scratching and chipping phenomena during the demolding process, ensuring that the surface of the component is perfectly undamaged.

[0014] Significantly improves molding accuracy: In traditional molds, misalignment at the joint between the inner mold and the side mold of the bay window can easily create steps, resulting in an uneven bottom plate of the bay window. However, this utility model can precisely control the lifting stroke of the inner mold and the middle mold through a lifting mechanism, so that the molding panel on the middle mold and the molding panel on the side mold can be precisely kept at the same height. This mechanical precision guarantee mechanism can make the bottom plate of the bay window after casting achieve a perfectly flat effect and completely eliminate joint misalignment.

[0015] Significantly improves production efficiency: Traditional mold dismantling requires external pushing equipment and multiple people to work together, which is cumbersome and time-consuming. However, this utility model adopts a lifting bay window inner mold and middle mold, combined with a modular quick-release connection structure. The entire mold dismantling process does not require heavy equipment assistance, which can significantly shorten the operation time and make production efficiency achieve a qualitative leap.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] like Figures 1 to 3 The precast bay window mold shown includes a middle mold 1 for an inner bay window, two side molds 2 for an inner bay window symmetrically arranged on both sides of the middle mold 1, and several outer molds for a bay window. The middle mold 1, the two side molds 2, and the several outer molds enclose a concrete pouring cavity. When assembling the mold, the middle mold 1 and the two side molds 2 are first aligned and placed close together. Then, the several outer molds are installed on the middle mold 1 and the side molds 2 to form a concrete pouring cavity. A concrete pouring inlet is left at the upper end of the middle mold 1.

[0020] It should be clarified that the core innovation of this application lies in the structural design of the inner mold 1 and the side mold 2 of the inner mold of the bay window. Therefore, the specific structure of the outer mold of the bay window will not be described in detail here. Those skilled in the art can clearly understand the specific structure of the outer mold of the bay window described in this embodiment and its connection relationship with other components in the mold through the prior art.

[0021] For the middle mold 1 of the bay window inner mold, in this embodiment, the middle mold 1 of the bay window inner mold includes a horizontally arranged upper forming panel 101 and a bottom plate 102 of the middle mold. In actual use, the bottom plate 102 of the middle mold is horizontally fixed on a prefabrication platform or a fixed frame. A lifting mechanism is installed between the upper forming panel 101 and the bottom plate 102 of the middle mold. The lifting mechanism is used to drive the upper forming panel 101 of the middle mold to move up and down. In this embodiment, the upper forming panel 101 of the middle mold is lifted up and down by the lifting mechanism. This not only facilitates the rapid demolding of the middle mold 1 of the bay window inner mold after molding, but also allows for a certain amount of operable space in the middle area of ​​the mold after the middle mold 1 of the bay window inner mold has completed shrinkage demolding. This facilitates the non-destructive demolding of the side mold 2 of the bay window inner mold. At the same time, in this embodiment, the relative position of the upper forming panel 101 of the middle mold and the upper forming panel 201 of the side mold can be adjusted by controlling the lifting stroke of the lifting mechanism to ensure the flush accuracy between the two and improve the flatness of the final component forming surface.

[0022] More specifically, the inner mold 1 of the bay window further includes an upper supporting channel steel 103, a lower supporting channel steel 104, a supporting column 105, and a supporting angle steel 106; the upper forming panel 101 of the inner mold is fixedly installed on the upper surface of the upper supporting channel steel 103, and the upper supporting channel steel 103 is mainly used to distribute the pressure borne by the upper forming panel 101 of the inner mold during concrete pouring; the two sides of the upper forming panel 101 of the inner mold extend outside the support area of ​​the upper supporting channel steel 103, and the supporting angle steel 106 is fixedly connected below the cantilevered part of the upper forming panel 101 of the inner mold, and the cantilevered part is mainly used for flush positioning with the side mold 2 of the inner mold of the bay window; the lower supporting channel steel 104 is fixedly connected to the bottom plate 102 of the inner mold through the vertically arranged supporting column 105, and the lower supporting channel steel 104, the supporting column 105, and the bottom plate 102 of the inner mold together bear the pouring pressure from the upper forming panel 101 of the inner mold through a lifting mechanism.

[0023] For the side mold 2 of the inner mold of the bay window, in this embodiment, the side mold 2 of the inner mold of the bay window includes a side mold upper forming panel 201, a side mold side forming panel 202, and a side mold base plate 203; the side mold upper forming panel 201 is horizontally flush with and adjacent to the middle mold upper forming panel 101, and the two are combined to form a horizontal forming surface of the prefabricated bay window outer shape surface; the side mold base plate 203 is horizontally flush with the middle mold base plate 102, and the side mold base plate 203 is also horizontally fixed on the prefabrication platform or fixed frame; the side mold upper forming panel 201 and the side mold base plate 203 are aligned with each other at the end away from the middle mold 1 of the inner mold of the bay window, and the side mold side forming panel 202 is vertically installed at the end of the side mold upper forming panel 201 and the side mold base plate 203 away from the middle mold 1 of the inner mold of the bay window.

[0024] More specifically, the inner mold side mold 2 of the bay window also includes a connecting plate 204. The connecting plate 204 is vertically installed below the upper forming panel 201 of the side mold, and one end of the upper forming panel 201 of the side mold, near the middle mold 1 of the inner mold of the bay window, extends out of the connection position of the connecting plate 204. The overhang of the upper forming panel 201 of the side mold is adjacent to the overhang of the upper forming panel 101 of the middle mold, and is supported by the supporting angle steel 106. One side of the supporting angle steel 106 is fixedly connected to the lower surface of the overhang of the upper forming panel 101 of the middle mold, and the other side is detachably connected to the connecting plate 204. The supporting angle steel 205 is not only used to support the two overhangs, but also to position the upper forming panel 101 of the middle mold and the upper forming panel 201 of the side mold, ensuring that the two are horizontally aligned.

[0025] Combining all the above technical features, the assembly process of the prefabricated bay window mold in this embodiment is as follows: First, the middle mold base plate 102 of the middle mold 1 of the bay window inner mold is fixed on the prefabrication platform or fixed frame; then, the side molds 2 of the bay window inner mold are installed on both sides of the middle mold 1 of the bay window inner mold. According to the height position of the forming panel 201 on the side mold, the height of the forming panel 101 on the middle mold is adjusted up and down by the lifting mechanism so that the lower surface of the overhang of the forming panel 201 on the side mold is attached to the upper surface of the supporting angle steel 106, and the side molds 2 of the bay window inner mold are moved so that the forming panel 201 on the side mold is closely joined with the forming panel 101 on the middle mold. Then, the supporting angle steel 106 and the connecting plate 204 are connected by bolts; finally, the bay window outer mold is connected to the middle mold 1 and the side molds 2 of the bay window inner mold.

[0026] After the mold is assembled, concrete can be poured. After the concrete is poured, the mold can be removed. The demolding process is as follows: First, remove the connecting bolts between the supporting angle steel 106 and the connecting plate 204; then, use the lifting mechanism to lower the forming panel 101 on the middle mold to detach it from the forming surface, thus completing the demolding of the middle mold 1 of the bay window inner mold; finally, remove the side mold 2 of the bay window inner mold and the bay window outer mold. Since the middle mold 1 of the bay window inner mold has been moved aside, there is no resistance to the subsequent demolding operation. Example

[0027] This embodiment is a further preferred embodiment of embodiment 1. In this embodiment, the lifting mechanism includes a top screw 107 and a screw bolt 108 threadedly engaged with the top screw 107. The top screw 107 vertically penetrates the lower support channel steel 104, and the top screw 107 and the lower support channel steel 104 are in sliding engagement. The top of the top screw 107 is fixedly connected to the upper support channel steel 103, and the top screw 107 moves up and down through the screw bolt 108.

[0028] Specifically, the lead screw 108 includes a fixing bolt 1081, an upward drive bolt 1082, and a downward drive bolt 1083; the fixing bolt 1081 is fixedly connected to the upper support channel steel 103, and the upper end of the top screw 107 passes through the fixing bolt 1081 and is fixedly connected to the upper support channel steel 103; the upward drive bolt 1082 and the downward drive bolt 1083 are respectively installed above and below the lower support channel steel 104, and respectively abut against the upper and lower surfaces of the lower support channel steel 104.

[0029] This embodiment uses a mechanical lifting method with a top screw 107 and screw bolt 108. It should be clarified that the fixing bolt 1081 serves to improve the connection stability between the top screw 107 and the upper support channel steel 103, while the upward drive bolt 1082 and the downward drive bolt 1083 are the main components that drive the top screw 107 and the upper forming panel 101 of the middle mold to move up and down. Specifically: When the upper forming panel 101 of the middle mold does not need to be adjusted up and down, the upper driving bolt 1082 and the lower driving bolt 1083 abut against the upper and lower surfaces of the lower support channel steel 104 respectively to limit and support. When the upper forming panel 101 of the middle mold needs to move upward, the lower driving bolt 1083 needs to be loosened first to move it away from the lower surface of the lower support channel steel 104, and then the upper driving bolt 1082 is tightened. Due to the limit of the upper surface of the lower support channel steel 104, the top screw 107 gradually rises, thereby driving the upper forming panel 101 of the middle mold to move upward. After reaching the target position, the lower driving bolt 1083 is tightened again to make it abut against the lower surface of the lower support channel steel 104. When the upper forming panel 101 of the middle mold needs to descend, the upward drive bolt 1082 needs to be loosened first. If the concrete adhesion on the upper forming panel 101 of the middle mold is small, the upper forming panel 101 of the middle mold and the top screw rod 107 can fall freely under their own gravity, so that the upward drive bolt 1082 always remains in contact with the upper surface of the lower support channel steel 104, thereby achieving automatic demolding. If the concrete adhesion on the upper forming panel 101 of the middle mold is large, after loosening the upward drive bolt 1082, the upper forming panel 101 of the middle mold and the top screw rod 107 can fall freely under their own gravity, so that the upward drive bolt 1082 always remains in contact with the upper surface of the lower support channel steel 104, thereby achieving automatic demolding. If the lead screw 107 is not able to fall freely under its own weight, then the downward drive bolt 1083 needs to be tightened. Due to the limitation of the lower surface of the lower support channel steel 104, the top screw 107 is pulled by the tension and drives the upper forming panel 101 of the middle mold to complete the demolding. After demolding, the upper forming panel 101 of the middle mold and the top screw 107 can fall freely under their own weight, so that the upward drive bolt 1082 abuts against the lower support channel steel 104 again. Finally, the downward drive bolt 1083 is tightened again so that it abuts against the lower surface of the lower support channel steel 104. Example

[0030] This embodiment is a further preferred embodiment of embodiment 1. In this embodiment, the middle mold 1 of the bay window inner mold also includes a limiting post 109. The limiting post 109 is vertically installed on the middle mold base plate 102. The height of the limiting post 109 is greater than the height of the lower support channel steel 104. The limiting post 109 is a square steel. The function of the limiting post 109 is to control the falling stroke of the upper forming panel 101 and the top screw rod 107 of the middle mold. Example

[0031] This embodiment is a further preferred embodiment of embodiment 1. In this embodiment, the inner mold side mold 2 of the bay window further includes a plurality of supporting ribs 205. The supporting ribs 205 are fixedly installed between the upper forming panel 201, the side forming panel 202, the bottom plate 203 and the connecting plate 204 of the side mold, and are perpendicular to the upper forming panel 201, the side forming panel 202, the bottom plate 203 and the connecting plate 204 of the side mold. The function of the supporting ribs 205 is to improve the pressure bearing capacity of the inner mold side mold 2 of the bay window.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
