Description

Technical Field

[0001] This utility model relates to the technical field of window sill construction, and in particular to a prefabricated device for improving the efficiency of bricklaying construction on the upper part of the window sill coping. Background Technology

[0002] Currently, installing a concrete capping on the windowsill of a masonry infill wall can effectively solve the problems of cracks and water leakage at the 45-degree angled section at the bottom corner of the window. However, according to specifications and design requirements, the windowsill capping needs to be embedded into the walls at both ends for a certain length, such as at least 240mm as required by the specifications.

[0003] The traditional method of constructing a window sill coping involves pausing construction when the infill wall reaches the window sill position, installing the coping formwork, laying reinforcement bars, and pouring concrete. After pouring, the brickwork of the upper wall continues. This method requires workers to stop and wait, resulting in excessively long construction time, affecting the construction progress and reducing work efficiency. Another method is for workers to leave a length for the coping to enter the wall during construction, and then pour the concrete coping later. However, this method causes the brick wall to be in a partially cantilevered state at the coping position, which is prone to uneven cracking and settlement. Furthermore, the pouring of the concrete coping in the later section extending into the wall is difficult, and the concrete filling is not full, leading to problems such as honeycomb surface and leakage later.

[0004] The existing construction method involves setting up U-shaped precast components at both ends of the window sill, then setting the openings of the precast components opposite each other, and then laying bricks on the top wall of the precast components. In this way, the precast components can serve as cantilever supports at the brickwork of the window sill, and also leave space for pouring the coping of the window sill.

[0005] The existing technical solutions mentioned above have the following drawbacks: When the window sill extends into the opening of the precast component, the openings of the precast component at both ends of the window sill will be sealed when the formwork is erected. This causes the concrete inside the precast component to be unable to be vibrated and to flow freely. As a result, the concrete at the opening of the precast component where the window sill extends into the precast component will develop honeycomb pitting after solidification. It may even cause water seepage at the opening of the precast component due to uneven settlement of the materials inside the concrete. This problem urgently needs to be solved. Utility Model Content

[0006] The purpose of this invention is to provide a prefabricated device that improves the efficiency of bricklaying construction on the upper part of the window sill coping, and which also improves the construction quality of the window sill coping.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A prefabrication device for improving the construction efficiency of bricklaying above the window sill coping, comprising a prefabrication sleeve for manufacturing U-shaped prefabricated parts. The prefabrication sleeve includes an inner sleeve in a U-shaped configuration and an outer sleeve in a C-shaped configuration. The outer sleeve is sleeved outside the inner sleeve, and a U-shaped prefabrication groove for concrete forming is formed between the inner sleeve and the outer sleeve. Sealing plates for closing both ends of the prefabrication groove are provided at both ends of the opening of the inner sleeve. A connecting flange is provided on one side of the sealing plate away from the inner sleeve, and a fixing device for fixing the opening ends of the inner sleeve and the outer sleeve is provided on the connecting flange. One side wall of the inner sleeve provided with the connecting flange is inclined and bent towards the side wall of the outer sleeve, and the distance between the bent side wall of the inner sleeve and the side wall of the outer sleeve is gradually decreasing, and the distance between one end of the inner sleeve provided with the connecting flange and the outer sleeve is the smallest.

[0009] By adopting the above technical solution, a prefabrication groove is formed between the inner sleeve and the outer sleeve, and the prefabrication groove is in a U-shaped configuration. Since one side wall of the inner sleeve is bent towards the side wall of the outer sleeve, it will result in that the prefabrication groove is gradually decreasing at the bent part of the inner sleeve. When the concrete of the prefabricated part solidifies in the prefabrication groove, an inclined inward vibrating groove will be formed on one end face of the opening of the U-shaped prefabricated part. In this way, after the formwork of the window sill coping is supported between two prefabricated parts, the vibrating groove can connect the outside and the inside of the prefabricated part. The operator can insert a vibrating rod into the prefabricated part through the vibrating groove for vibration, or can also insert other stirring tools into the prefabricated part through the vibrating groove to stir the concrete in the prefabricated part, ensuring that the window sill coping extending into the prefabricated part can also be stirred, so as to ensure that the concrete extending into the prefabricated part can be evenly stirred, and further ensure the construction quality of the window sill coping inside the prefabricated part.

[0010] Further, the fixing device includes covering flanges fixed at both ends of the opening of the outer sleeve. The covering flanges are fitted on one surface of the connecting flange, and a number of fixing bolts are inserted through the connecting flange and the covering flanges.

[0011] By adopting the above technical solution, the inner sleeve and the outer sleeve can be initially positioned when forming the prefabrication groove through the covering flanges and the connecting flange, and then the inner sleeve and the outer sleeve are finally fixed through the fixing bolts, so that the formation and use of the prefabrication groove are more stable.

[0012] Further, a number of fish scales are provided on one side of the inner sleeve close to the outer sleeve and on one side of the outer sleeve close to the inner sleeve.

[0013] By adopting the above technical solution, the fish scales can make a number of holes formed on both the inner and outer surfaces after the prefabricated part is formed. In this way, the integrity of the connection between the window sill coping and the bricklaying mortar is better during the connection process with the prefabricated part, so that the connection between the prefabricated part and other components is more stable.

[0014] In summary, the beneficial technical effects of this utility model are as follows:

[0015] 1. The use of an inner shell, an outer shell, and an inclined inner shell sidewall improves the construction quality of the window sill coping.

[0016] 2. Connecting flanges, covering flanges, and fixing bolts are used to connect the inner shell and the outer shell together;

[0017] 3. Fish scales were used, which improved the tightness of the connection between the window sill and the prefabricated components. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Reference Figure 1 and Figure 2 This utility model discloses a prefabricated device for improving the construction efficiency of bricklaying on the upper part of a window sill. It includes a pre-support shell 1 for making U-shaped prefabricated parts. The pre-support shell 1 includes an outer shell 12 arranged in a C-shape and an inner shell 2 arranged in a Z-shape. The outer shell 12 is fitted over the inner shell 2, and an inverted U-shaped prefabricated groove 11 can be formed between the outer shell 12 and the inner shell 2.

[0024] Reference Figure 1 and Figure 2 To expedite the construction of the existing window sill, the inner shell 2 and outer shell 12 are now fitted together. A plastic film is laid on a flat ground, and then the inner shell 2 and outer shell 12, forming the precast groove 11, are laid down on the plastic film. Finally, a release agent is applied to the outer wall of the inner shell 2 and the inner wall of the outer shell 12, and a steel reinforcement frame is placed in the precast groove 11. Finally, concrete is poured into the precast mold and vibrated. The formed precast components are placed on both sides of the window sill, with the openings of the precast components at both ends of the window sill facing opposite directions. The window sill cap penetrates the window sill and extends into the opening of the precast component.

[0025] Reference Figure 1 and Figure 2 In this design, one side of the inner shell 2 bends towards the side wall of the outer shell 12. As a result, the inner side of one side of the precast groove 11 is set in an inclined state. From the open end face of the precast component, a vibration groove is formed that connects the inside and outside of the precast component opening. After the formwork for the window sill capping is supported between the two precast components, the vibration groove can connect the outside and the inside of the precast component. The operator can insert the vibrator into the precast component through the vibration groove to vibrate, or insert other mixing tools into the precast component through the vibration groove to mix the concrete inside the precast component. This ensures that the window sill capping extending into the precast component can also be mixed, thereby ensuring that the concrete extending into the precast component can be mixed evenly, and thus ensuring the construction quality of the window sill capping inside the precast component.

[0026] Reference Figure 1 and Figure 2 A sealing plate 22 is provided on the side wall of the opening of the inner shell 2. A connecting flange 23 is provided on the side of the sealing plate 22 away from the inner shell 2. The sealing plate 22 spans across the width of the precast groove 11 and is used to seal the gap between the inner shell 2 and the outer shell 12. When the outer shell 12 is fitted over the inner shell 2, the covering flange 13 is attached to the surface of the connecting flange 23. Then, the relative position of the inner shell 2 and the outer shell 12 can be fixed and stabilized by fixing bolts. In order to further improve the construction quality of the window sill coping, several fish scales 21 are evenly distributed on the outer side wall of the inner shell 2 and the inner side wall of the outer shell 12. In this way, there will be many holes on the inner and outer surfaces of the precast component, which provides more connection area for subsequent connection with the window sill coping and the mortar connection of the masonry wall.

[0027] Reference Figure 3 In this design, the U-shaped precast component is placed flat, with one side having a vibration groove at the top and the other side without a vibration groove at the bottom. The bottom edge of the precast component is designed as a slope with an inner higher surface and an outer lower surface, meaning that the width of the top surface of the bottom edge of the precast component is inclined. This way, when the window sill coping is formed inside the precast component, even if there is water seepage at the concrete joint, the height difference will prevent it from reaching the top surface of the bottom edge of the precast component, thus further improving the water-proofing ability of the window sill coping.

Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
