Description

Technical Field

[0001] This utility model relates to the field of concrete mold technology, specifically to a precast window sill capping concrete block mold. Background Technology

[0002] As an important component of the building's exterior wall structure, the function of the window sill coping is to prevent rainwater from seeping into the interior of the wall along the window sill, while also enhancing the overall integrity of the structure around the window opening. Traditionally, the window sill coping is constructed by casting concrete on-site with formwork. However, cast-in-place concrete requires a curing period, which affects construction efficiency, and it is difficult to guarantee the quality of the finished product, especially in rainy or low-temperature environments.

[0003] In recent years, in order to improve construction efficiency, precast concrete window sill capping has been gradually promoted and applied. However, the mold technology it relies on still has certain defects. Most existing precast molds are fixed-size structures and cannot flexibly adjust the length, which leads to the need to customize multiple sets of molds for different projects, increasing material costs and storage pressure. In addition, existing molds are relatively troublesome to assemble and disassemble, affecting the pouring efficiency. Therefore, a device is needed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a precast window sill capping concrete block mold, which solves the problems of inconvenient size adjustment and cumbersome assembly and disassembly of existing casting molds.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a precast window sill capping concrete block mold, including a base plate, side plates and a connecting mechanism, wherein the side plates include an extension plate, a baffle and an inclined plate, and the number of extension plates is at least two, and the base plate, extension plates, baffle and inclined plate form a casting space with the opening facing.

[0006] The extension plate is fixedly connected to the upper surface of the base plate. The baffle and the inclined plate are respectively provided on both sides of the extension plate. The bottom of the extension plate is provided with a fixing mechanism to fix the extension plate to the upper surface of the base plate.

[0007] The number of connecting mechanisms is multiple, and they are respectively located between the extension plate and the baffle, and between the extension plate and the inclined plate.

[0008] Optionally, the connecting mechanism includes a connecting buckle, a fixing seat, and a limiting strip. The connecting buckle is located on one side of the extension plate and the baffle, and the fixing seat is located on one side of the extension plate and the inclined plate. The limiting strip passes through the connecting buckle and the fixing seat to fix adjacent side plates. The fixing seat has a limiting mechanism inside to prevent the limiting strip from moving.

[0009] Optionally, the limiting mechanism includes a compression spring and a limiting block. The bottom of the limiting strip has limiting teeth. The limiting block is slidably connected to the inner wall of the fixed seat and engages with the limiting teeth. The compression spring is located on the inner wall of the fixed seat and its top abuts against the bottom of the limiting block to push the limiting block upward.

[0010] Optionally, the fixing mechanism includes a slide groove, a slider, a connecting seat, and a fixing nut. The slide groove is formed on one side of the base plate. The top of the slider passes through the slide groove and is guided to the slide groove. The connecting seat is fixedly connected to one side of the extension plate. The top of the slider passes through the connecting seat. The fixing nut is threaded onto the outer surface of the slider and abuts against the upper surface of the connecting seat.

[0011] Optionally, guide grooves and guide blocks are provided at both ends of the base plate along its length, and the guide grooves and guide blocks are connected to guide each other for splicing adjacent base plates.

[0012] Optionally, a lever is rotatably connected to the side of the base plate near the guide block. The lever is used to close one side of the guide block to prevent the guide block from separating from the guide groove.

[0013] Optionally, a plurality of positioning blocks are fixedly connected to one side of the upper surface of the base plate, and one side of the positioning block abuts against the outer surface of the extension plate to reduce the tilt of the extension plate.

[0015] This utility model provides a precast concrete block mold for window sill coping, which has the following advantages:

[0016] This utility model provides a precast window sill capping concrete block mold. Through the cooperation of the base plate and side plates, the side plates can be enclosed into a rectangle, and then the concrete can be poured within the rectangle enclosed by the side plates. Further cooperation with the extension plate and connecting mechanism set in the middle allows the length of the poured precast window sill to be adjusted to adapt to different needs. The connecting mechanism allows for quick disassembly and assembly of the baffle, inclined plate and extension plate, shortening the connection time and improving the flexibility of the device during use. The fixing mechanism set at the bottom of the extension plate can fix the extension plate to the base plate, ensuring the perpendicularity of the extension plate to the base plate and reducing the occurrence of tilting of the extension plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a precast window sill capping concrete block mold, including a base plate 1, side plates and a connecting mechanism. The side plates include an extension plate 2, a baffle 3 and an inclined plate 4. The number of extension plates 2 is at least two. The base plate 1, extension plates 2, baffle 3 and inclined plate 4 form a pouring space with the opening facing.

[0025] The extension plate 2 is fixedly connected to the upper surface of the base plate 1. The baffle 3 and the inclined plate 4 are respectively provided on both sides of the extension plate 2. The bottom of the extension plate 2 is provided with a fixing mechanism to fix the extension plate 2 to the upper surface of the base plate 1.

[0026] There are multiple connecting mechanisms, which are respectively located between the extension plate 2 and the baffle 3, and between the extension plate 2 and the inclined plate 4.

[0027] Adjust the number of extension plates 2 spliced ​​according to the required length of the window sill. After adjustment, install baffle 3 and inclined plate 4 on both sides of extension plate 2. Use the connecting mechanism to fix the three together. After fixing, use the fixing mechanism to fix the enclosed rectangle on the base plate 1 to form a pouring cavity. Pour the concrete into the cavity.

[0028] In this embodiment, as a preferred solution, the connecting mechanism includes a connecting buckle 5, a fixing seat 6, and a limiting strip 7. The connecting buckle 5 is located on one side of the extension plate 2 and the baffle 3, and the fixing seat 6 is located on one side of the extension plate 2 and the inclined plate 4. The limiting strip 7 passes through the connecting buckle 5 and the fixing seat 6 to fix the adjacent side plates. The fixing seat 6 is provided with a limiting mechanism inside to prevent the limiting strip 7 from moving.

[0029] After the limiting strip 7 passes through the limiting buckle and is inserted into the fixing seat 6, the limiting mechanism in the fixing seat 6 limits the position of the limiting strip 7 to prevent the limiting strip 7 from shaking. One side of the limiting strip 7 has a protrusion that can be locked together with the connecting buckle 5. After the position of the limiting strip 7 is fixed, the position of the connecting buckle 5 and the fixing seat 6 can be fixed, thereby fixing the adjacent extension plate 2 together.

[0030] In this embodiment, as a preferred option, the limiting mechanism includes a compression spring 8 and a limiting block 9. The bottom of the limiting strip 7 is provided with limiting teeth 10. The limiting block 9 is slidably connected to the inner wall of the fixed seat 6 and engages with the limiting teeth 10. The compression spring 8 is provided on the inner wall of the fixed seat 6 and its top abuts against the bottom of the limiting block 9 to push the limiting block 9 upward.

[0031] The compression spring 8 pushes the limiting block 9 upward. The bottom of the limiting block 9 is provided with a protruding tooth that cooperates with the limiting tooth 10. The protruding tooth can engage with the limiting tooth 10, thereby fixing the position of the limiting strip 7 and preventing the limiting strip 7 from moving. When disassembly is required, press the limiting block 9 downward. The limiting block 9 will press down the compression spring 8, and the limiting block 9 will separate from the limiting tooth 10, releasing the limitation on the limiting strip 7, thereby separating the fixing seat 6 and the connecting buckle 5.

[0032] In this embodiment, as a preferred solution, the fixing mechanism includes a slide groove 11, a slider 12, a connecting seat 13, and a fixing nut 14. The slide groove 11 is formed on one side of the base plate 1. The top of the slider 12 passes through the slide groove 11 and is guided and connected to the slide groove 11. The connecting seat 13 is fixedly connected to one side of the extension plate 2. The top of the slider 12 passes through the connecting seat 13. The fixing nut 14 is threadedly connected to the outer circular surface of the slider 12 and abuts against the upper surface of the connecting seat 13.

[0033] The slider 12 slides on the inner wall of the groove 11. A threaded post is provided above the slider 12. After the fixing nut 14 is screwed on the slider 12, the connecting seat 13 can be pressed together with the groove 11, thereby fixing the extension plate 2 on the base plate 1. After the position of the extension plate 2 is fixed, the baffle 3 and the inclined plate 4 are installed on both sides of the extension plate 2 for pouring. The lower surface of the connecting seat 13 is provided with knurling to increase the sliding friction with the surface of the groove 11 and further reduce the shaking of the extension plate 2.

[0034] In this embodiment, as a preferred solution, guide grooves 15 and guide blocks 16 are respectively provided at both ends of the base plate 1 along its length. The guide grooves 15 and guide blocks 16 are connected to each other to splice adjacent base plates 1. A lever 17 is rotatably connected to the side of the base plate 1 near the guide block 16. The lever 17 is used to close one side of the guide block 16 to prevent the guide block 16 and the guide groove 15 from separating.

[0035] The guide groove 15 and the guide block 16 can be slidably connected together, thereby splicing the two base plates 1 together. The paddle 17 is located at both ends of the guide block 16. After rotating the paddle 17 to one side of the guide block 16, one side of the guide block 16 can be closed, preventing the guide block 16 and the guide groove 15 from moving relative to each other, thereby fixing the position of the guide block 16.

[0036] In this embodiment, as a preferred option, a plurality of positioning blocks 18 are fixedly connected to one side of the upper surface of the base plate 1. One side of the positioning block 18 abuts against the outer surface of the extension plate 2 to reduce the tilt of the extension plate 2.

[0037] The side of the positioning block 18 near the extension plate 2 is a plane, which is perpendicular to the base plate 1. When fixing the extension plate 2, ensure that the extension plate 2 is in contact with the positioning block 18, so that the tilt angle of the extension plate 2 can be determined, making the extension plate 2 perpendicular to the base plate 1.

[0038] In this embodiment, as a preferred option, a through hole 19 is provided on one side of the inclined plate 4 for passing through the reinforcing bar.

[0039] A reinforcing bar is passed through through hole 19 to enhance the strength of the windowsill.

[0040] In this invention, the working steps of the device are as follows:

[0041] 1. Select the corresponding number of extension plates 2 according to the required length of the window sill. Use the limiting strip 7 to splice multiple extension plates 2 together. After splicing, place the extension plates 2 on the base plate 1, adjust the position of the slider 12, and use the fixing nut 14 to fix the extension plates 2 on the base plate 1.

[0042] 2. After fixing the extension plate 2, install the baffle 3 and the inclined plate 4 on both sides of the extension plate 2 and fix them with the limiting strip 7, and pass the reinforcing bar through the through hole 19.

[0043] 3. After the adjustment is completed, pour the concrete. After the concrete has solidified, press the limiting block 9 to remove the limiting strip 7 from the fixing seat 6. Separate the extension plate 2, baffle 3, and inclined plate 4. Unscrew the fixing nut 14 to separate the base plate 1 from the extension plate 2. After separation, take out the poured windowsill.
