Description

Technical Field

[0001] This invention belongs to the field of window sill coping construction technology, specifically relating to a three-section post-cast window sill coping construction structure. Background Technology

[0002] In building construction, the coping of window sills is usually constructed using a direct pouring method. This method requires pausing the masonry work when the wall reaches the coping height, then installing reinforcing bars and formwork before pouring concrete. Construction of the upper masonry can then resume after the coping is poured. However, this method significantly restricts the construction progress, and workers often reverse the order of operations to improve efficiency. For example, they may leave a groove for the coping to extend into the wall during construction and then pour concrete later. This causes the brick wall to be under partial cantilever stress during construction, which can easily lead to uneven cracking and settlement. Furthermore, the later pouring of concrete into the section extending into the wall is difficult and can easily result in incomplete concrete pouring, honeycomb-like surfaces, and subsequent leakage.

[0003] For example, a Chinese patent discloses a precast concrete block for window sill coping (patent publication number: CN114837344A). This precast concrete block features a simple structure and convenient manufacturing. Reinforcing bars are pre-embedded within the precast concrete block, resulting in a small size and light weight, facilitating transport to the construction floor and reducing technical downtime caused by pouring concrete for coping. This saves on construction time and labor costs. While this technical solution addresses the current problem of low efficiency in window sill coping, in actual construction, most window sills are not fixed in size. Although the precast concrete block's dimensions can be adjusted during manufacturing, cast-in-place sections typically require formwork before pouring. The formwork's dimensions are often unsuitable for most cast-in-place window sill sections. Therefore, it is usually necessary to fabricate suitable formwork on-site according to different window sizes, which is time-consuming and labor-intensive. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a three-section post-cast window sill coping construction structure to solve the problem that in the current window sill coping construction process, it is necessary to build appropriate templates according to different window sizes, which is time-consuming and labor-intensive.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A three-section post-cast window sill coping construction structure includes a wall and a window sill reserved during wall construction. Two precast coping blocks are spaced apart on the upper surface of the window sill. Both precast coping blocks are the same width as the wall, and one end of each block is embedded into the wall by a certain distance. Through holes are formed on the surface of both precast coping blocks, with the through holes extending along the width of the wall. Support plates are detachably connected to the outer surfaces of each precast coping block through the through holes. One side of each support plate... The surfaces are all in close contact with the wall surface. Each of the support plates has a movable plate that moves along the length of the windowsill on one side surface. The two movable plates on each side of the windowsill are symmetrically arranged about the windowsill. Multiple connecting plates can be detachably connected between the two movable plates that are arranged opposite each other in the same vertical plane. The multiple connecting plates are all arranged along the length of the windowsill. The two opposite sides of the two precast coping blocks, the upper surface of the windowsill, and the opposite sides of the movable plates and connecting plates together form a casting chamber for making the cast-in-place coping section.

[0007] Furthermore, the height of the movable plate and the connecting plate is greater than the height of the precast block; the two adjacent connecting plates and the connecting plate and the movable plate can slide vertically and be detachably connected by a tenon and mortise structure, and the movable plate and the connecting plate together form a flat surface and are in close contact with the wall.

[0008] Furthermore, each of the support plates has a vertically arranged strip-shaped through hole on the side surface near the wall, and the strip-shaped through hole corresponds to the through hole; the support plates on both sides of the capping precast block are tightly attached to the wall surface by bolts and nuts, and the bolts pass through the through hole and the corresponding strip-shaped through hole.

[0009] Furthermore, a limiting block is inserted between two support plates set on both sides of the wall and positioned opposite each other. The limiting block moves along the width of the wall, and when any surface of the limiting block abuts against the surface of the wall or the surface of the precast coping block, the support plate is exactly in a horizontal position; the length of the limiting block is greater than the width of the precast coping block.

[0010] Furthermore, each of the support plates has a locking block fixedly connected to the side of its surface away from the wall. Multiple locking blocks in the same vertical plane are detachably connected to a support block. The support block slides horizontally along the length of the windowsill. The movable plate and the connecting plate have a stop block fixedly connected to the side of their surfaces away from the wall. Each of the connecting plate and the movable plate has a pressure block elastically inserted horizontally on the side of its surface away from the wall. One end of each pressure block has a smooth surface and protrudes from the surface of the connecting plate and the movable plate. The protruding end of each pressure block is on the movement path of the support block.

[0011] Furthermore, each of the connecting plates has a connecting lug fixed to its top, and the two corresponding connecting lugs on both sides of the windowsill are tightened together by bolts and nuts.

[0012] The beneficial effects of this invention are as follows:

[0013] 1. This invention uses support plates fixed to both sides of the precast coping block as fixed ends. The support plates are fixedly connected to the precast coping block by bolts and nuts. The template composed of connecting plates and movable plates is fixedly connected to the support plates. By extending the length of the bolts, the template can be adapted to window sills of different widths. By using multiple connecting plates to cooperate to form one side template of the casting chamber, it can also be adapted to window sills of different lengths. Through the strip-shaped through holes set on the support plate, the position of the connecting plate can be moved vertically within a certain range, thereby making the template adaptable to window sills of different heights. This effectively improves the applicability of the invention. Construction workers no longer need to make different coping cast-in-place section templates according to the window sill size, effectively reducing the construction process and workload. Furthermore, the various parts of this invention can be reused after use, further reducing construction costs.

[0014] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0023] like Figures 1-5 As shown,

[0024] A three-section post-cast window sill coping construction structure includes a wall 1 and a window sill 2 reserved during the construction of the wall 1. Two precast coping blocks 3 are spaced apart on the upper surface of the window sill 2, symmetrically arranged about the window sill 2. Both precast coping blocks 3 are the same width as the wall 1, and one end of each precast coping block 3 is embedded 150mm into the wall. Multiple protruding precast steel bar joints 4 (only 4 are shown in the figure) are provided on the opposite sides of each precast coping block 3. These joints are arranged along the length of the window sill 2, and are evenly spaced circumferentially along the end face of each precast coping block 3. Through holes are provided on the surface of both precast coping blocks 3, arranged along the width of the wall 1. Support plates 5 are detachably connected to the two outer sides of each precast coping block 3 through the through holes. One side surface of each support plate 5 is in close contact with the surface of the wall 1. One side surface of each support plate 5 is slidably connected to a movable plate 6 that moves along the length of the windowsill 2. The movable plate 6 moves within the length range of the precast coping block 3 and is in close contact with its surface. The two movable plates 6 respectively set on both sides of the windowsill 2 are symmetrically arranged about the windowsill 2. Multiple connecting plates 7 can be detachably connected between the two movable plates 6 arranged opposite each other in the same vertical plane. The connecting plates 7, movable plates 6 and the same side surface of the support plate 5 are all in the same vertical plane. The multiple connecting plates 7 are all arranged along the length of the windowsill 2. The opposite side surfaces of the two precast coping blocks 3, the upper surface of the windowsill 2, and the opposite side surfaces of the movable plates 7 and connecting plates 7 together form a casting chamber. The steel reinforcement skeleton 8 of the cast-in-place section 16 of the coping is placed in the casting chamber. After the steel reinforcement skeleton 8 is tied to the precast steel reinforcement joint 4 with iron wire, concrete is poured into the casting chamber.

[0025] Combination Figure 1 and Figure 2As shown, construction is paused when wall 1 reaches the coping elevation of window sill 2. Pre-fabricated coping blocks 3 are placed in their corresponding positions according to the dimensions of window sill 2. Multiple support plates 5 are fixedly connected to the corresponding coping blocks 3, and the support plates 5 are adjusted to a horizontal position. An appropriate number of connecting plates 7 are selected based on the length of window sill 2, and the connecting plates 7 are fixedly connected to the movable plate 6. Adjacent connecting plates 7 are also fixedly connected to each other. At this point, one side surface of multiple connecting plates 7, movable plate 6, and support plates 5 all abuts against the surface of wall 1. Multiple connecting plates 7 and movable plate 6 together form one side of the formwork for the pouring chamber. The pre-fabricated steel reinforcement cage 8 is tied to the pre-fabricated steel reinforcement joint 4 with wire, allowing the pouring chamber to be filled. Indoor concrete is poured and a cast-in-place capping section 16 is constructed. By fixing the support plate 5 to the capping precast block 3 as the fixed end, multiple movable plates 6 of fixed size are detachably connected between two adjacent movable plates 6 as movable ends. The corresponding number of connecting plates 7 can be added according to the window sill 2 of different lengths, which is suitable for building templates on window sills 2 of different sizes, effectively improving the scope of application. Furthermore, since the movable plates 6 are slidably set on one side of the support plate 5, the number and position of the connecting plates 7 can be finely adjusted by adjusting the distance between the movable plates 6 and the support plate 5, so that the template composed of multiple connecting plates 7 and movable plates 6 can be tightly attached to the capping precast block 3 and the two sides of the wall 1, ensuring the sealing of the pouring chamber.

[0026] In this embodiment, the height of the movable plate 6 and the connecting plate 7 is greater than the height of the precast block 3; the two adjacent connecting plates 7 and the connecting plate 7 and the movable plate 6 can slide vertically and be detachably connected by a tenon and mortise structure, and the movable plate 6 and the connecting plate 7 together form a flat surface and are in close contact with the wall 1.

[0027] Combination Figure 3 As shown, the height of the connecting plate 7 and the movable plate 6 is greater than the height of the precast coping block 3, which ensures that a part of the surface of the connecting plate 7 and the movable plate 6 can be tightly attached to the surface of the wall 1, preventing concrete leakage when pouring the cast-in-place coping section 16; the vertical sliding tenon structure facilitates the assembly and disassembly of the connecting plate 7, and can play a horizontal restriction role between adjacent connecting plates 7, ensuring that the connecting plate 7 is tightly attached to the surface of the wall 1, and also makes the surface of the side near the windowsill 2 remain flat after two adjacent connecting plates 7 are connected, so that the surface of the cast-in-place coping section 16 is flat and does not require the construction personnel to repair it again.

[0028] In this embodiment, each of the support plates 5 has a vertically arranged strip-shaped through hole 9 on the side surface near the wall 1, and the strip-shaped through hole 9 corresponds to the through hole; the support plates 5 on both sides of the capping precast block 3 are tightly attached to the surface of the wall 1 by means of bolt and nut connection, and the bolt passes through the through hole and the corresponding strip-shaped through hole 9.

[0029] As shown in the figure, when the support plate 5 and the precast coping block 3 are connected by bolts and nuts, since the height of the connecting plate 7 and the movable plate 6 is greater than the height of the precast coping block 3, the position of the support plate 5 can be adjusted vertically through the strip-shaped through hole 9, thereby adjusting the position of the connecting plate 7 and the movable plate 6 in the vertical direction, ultimately achieving the purpose of adjusting the height of the casting chamber. This invention can be applied to the production of cast-in-place coping sections 16 of different heights and sizes within a certain range, effectively improving the applicability of the invention. Furthermore, the support plate 5 and the precast coping block 3 are fixed by bolts and nuts, making the operation simple, convenient, and easy to disassemble and assemble.

[0030] In this embodiment, a limiting block 10 is provided between two support plates 5 arranged on both sides of the wall 1 and facing each other. The limiting block 10 is "L" shaped and moves along the width direction of the wall 1. When any surface of the limiting block 10 abuts against the surface of the wall 1 or the surface of the precast coping block 3, the support plate 5 is exactly in a horizontal position. The length of the limiting block 10 is greater than the width of the precast coping block 3.

[0031] When the support plate 5 is connected to the precast coping block 3 by bolts and nuts, the limiting block 10 is simultaneously inserted into the support plate 5 on both sides of the precast coping block 3. Since the precast coping block 3 and the wall 1 form a right angle structure, when the surface of the limiting block 10 abuts against the surface of the wall 1 or the surface of the precast coping block 3, both support plates 5 are in a horizontal position, which can quickly level the support plate 5. Then, the bolts and nuts are tightened on the leveled support plate 5. After the connecting plate 7 is installed, there is no need for secondary leveling, which effectively improves construction efficiency and ensures stability during subsequent construction.

[0032] In this embodiment, each of the support plates 5 has a locking block 11 fixedly connected to the side surface away from the wall 1. Multiple locking blocks 11 in the same vertical plane are detachably connected to a support block 12. The support block 12 slides horizontally along the length of the windowsill 2. The movable plate 6 and the connecting plate 7 have a stop block 13 fixedly connected to the side surface away from the wall 1. Each of the connecting plate 7 and the movable plate 6 has a pressure block 14 elastically inserted horizontally on the side surface away from the wall 1 (a spring is provided between the connecting plate 7, the movable plate 6 and the pressure block 14, which is not shown in the figure). One end of the pressure block 14 is smooth and protrudes from the surface of the connecting plate 7 and the movable plate 6. The protruding end of each pressure block 14 is on the movement path of the support block 12.

[0033] Combination Figure 4 and Figure 5As shown, when the support plate 5 is fastened to the precast coping block 3 by bolts and nuts, and the template composed of multiple connecting plates 7 is fixedly connected to the movable plate 6, when the support block 12 is engaged with the locking block 11 on one of the support plates 5 and moves along the length direction of the windowsill 2, the locking block 11 limits and guides the support block 12. During the movement, the surface of the support block 12 will abut against the pressure block 14, causing the pressure block 14 to move towards the windowsill 2. At the same time, the pressure block 14 will compress the spring, and the spring will compress and apply pressure to the surfaces of the corresponding connecting plates 7 and movable plates 6, so that the connecting plates 7 and movable plates 6 abut against the surface of the wall 1. When the support block 12 is simultaneously engaged with multiple locking blocks 11 on two support plates 5, the support block 12 can simultaneously engage multiple locking blocks 11 along its length direction. The pressure block 14 compresses the formwork, which is composed of the connecting plate 7 and the movable plate 6, so that the formwork is tightly attached to the surface of the wall 1, reducing the possibility of gaps between the surface of the wall 1 and the connecting plate 7 and the movable plate 6, thereby ensuring the sealing of the pouring chamber. When the support block 12 is fixedly connected to the locking block 11 on the surface of the two support plates 5, the stop block 13 on the surface of the connecting plate 7 just abuts against the surface of the support block 12. The connecting plate 7 is moved vertically and the stop block 13 on its surface abuts against the surface of the support block 12. At this time, the upper and lower surfaces of the connecting plate 7 and the movable plate 6 are on the horizontal plane. The support block 12 and the stop block 13 cooperate to not only provide vertical support for the connecting plate 7, but also to quickly adjust the connecting plate 7 and the movable plate 6 to the same horizontal position, effectively improving the efficiency of construction.

[0034] In this embodiment, each of the connecting plates 7 has a connecting lug 15 fixed to its top. The two corresponding connecting lugs 15 on both sides of the windowsill 2 are tightened by bolts and nuts, which further improves the contact strength between the connecting block and the surface of the wall 1 and reduces the generation of gaps.

[0035] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
