Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically a one-time casting structure for the flashing base layer and roof structure. Background Technology

[0002] Flashing is a waterproofing structure installed on building roofs, walls, and other surfaces at the junction of two different materials or at the turning points of building components to prevent the seepage of rainwater and other liquids. Currently, flashing uses a formwork support system for pouring concrete. The formwork typically requires bolts for fixation. The bolts connect to the formwork at both ends to ensure the spacing between formwork sections meets requirements, withstands the lateral pressure of the concrete, prevents deformation, and maintains the stability of the formwork's position and shape. Because bolts are used, removing the formwork is difficult or requires manual cutting.

[0003] Therefore, how to quickly and easily remove bolts when dismantling formwork during construction is a problem that urgently needs to be solved in existing technologies. Utility Model Content

[0004] The purpose of this utility model is to address the problem of how to quickly and easily remove bolts during the template dismantling process in the existing technology by setting up a one-time casting structure for the flashing base layer and the roof structure.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The flashing base layer and roof structure are formed by one-time casting, including template and screw rod, wherein the screw rod is snapped onto the template;

[0007] The template includes an exterior wall template and an interior wall template. The screw is used to fix the template and reduce deformation of the concrete structure. The screw passes through both the exterior and interior wall templates, keeping the central axis of the exterior and interior wall templates parallel. Furthermore, the central axis of the template is perpendicular to the ground in the building structure. The exterior wall template is located on the exterior side of the building structure, and the interior wall template is located on the interior side. A first hole is provided on the exterior wall template away from the ground, and a second hole is provided on the interior wall template away from the ground. The screw is installed corresponding to the first and second holes. The first and second holes are frame-like structures, with the area of ​​the first hole being larger than the area of ​​the second hole. The center point of the first hole and the center point of the second hole are on a straight line.

[0008] Preferably, the central axis of the screw intersects perpendicularly with the central axis of the template.

[0009] Preferably, the screw maintains a gap with the top surface of the concrete structure.

[0010] Preferably, the inner wall formwork is provided with a baffle on the side facing the outer wall formwork. The baffle is used to form a groove on the top surface of the concrete structure when pouring concrete. With the ground in the building structure as the projection surface, the length of the longest extension direction of the baffle matches the length of the longest extension direction of the inner wall formwork.

[0011] Preferably, the position of the baffle on the inner wall template is adjustable.

[0012] Preferably, the edge of the inner wall template facing the ground is configured as a curved surface.

[0013] Preferably, a support rod is provided on the side of the inner wall formwork facing the interior of the building structure. The support rod is used to reduce the deformation of the inner wall formwork. One side of the support rod is connected to the inner wall formwork, and the other side of the support rod is a free end. The free end of the support rod abuts against the floor of the interior of the building structure, and the support rod and the inner wall formwork form an acute angle fit.

[0014] Preferably, the screw includes a nut and a pipe. The nut is used to fix the template and reduce the template from slipping. The pipe is used to connect and cooperate with the nut through the template to maintain a certain distance between the outer wall template and the inner wall template.

[0015] Preferably, the nut and the pipe are detachably connected.

[0016] Preferably, the nut is provided with a washer, the washer being used to reduce slippage when the nut secures the pipe, and the washer being disposed on the side of the nut facing the pipe.

[0025] The present invention will now be described in detail with reference to the accompanying drawings.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0027] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] In the description of this utility model, it should be noted that the terms "upper," "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. These terms are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] In Example 1: The flashing base and roof structure of this utility model are formed by one-time casting, including a template 1 and a screw 2. The screw 2 is snapped onto the template 1. The template 1 includes an outer wall template 3 and an inner wall template 4. The screw 2 is used to fix the template 1 to reduce the deformation of the concrete structure. The screw 2 passes through the outer wall template 3 and the inner wall template 4 to keep the central axis of the outer wall template 3 parallel to the central axis of the inner wall template 4. Furthermore, the central axis of the template 1 is perpendicular to the ground in the building structure. The outer wall template 3 is set on the building... The inner wall formwork 4 is set on the side of the building structure facing the outside, and the outer wall formwork 3 is provided with a first hole 5 on the side away from the ground in the building structure. The inner wall formwork 4 is provided with a second hole 6 on the side away from the ground in the building structure. The screw 2 is installed corresponding to the first hole 5 and the second hole 6. The first hole 5 and the second hole 6 are frame structures. The area of ​​the first hole 5 is larger than the area of ​​the second hole 6. The center point of the first hole 5 and the center point of the second hole 6 are located on a straight line.

[0032] As a preferred embodiment, based on the above method, the central axis of the screw 2 is further perpendicular to the central axis of the template 1. This structural arrangement reduces force transmission between the screw 2 and the template 1 during construction, further improving the connection and fit between them.

[0033] The integrated roof structure of this invention allows for a mechanical connection between the screw rod 2 and the template. When the screw rod 2 passes through the first hole 5 and the second hole 6 to fix the template 1, an integrated flashing structure is formed. When the template needs to be removed after construction, since the area of ​​the first hole 5 is larger than that of the second hole 6, when a certain force is applied to the screw rod 2 from the inner wall template 4 side, the screw rod 2 moves along the inside of the first hole 5, causing the connection state between the screw rod 2 and the template 1 to change. This facilitates the quick removal of the screw rod 2 and reduces the removal time of the template 1.

[0034] Specifically, the template 1 can be a wooden template, an aluminum template, etc., and the screw 2 can be made of stainless steel, alloy, or other materials.

[0035] In Example 2: The flashing base layer and roof structure of this utility model are formed by one-time casting. Further, based on the above method, the screw 2 maintains a gap with the top surface of the concrete structure. This structural arrangement effectively reduces the damage to the concrete structure caused by the screw 2 when the formwork 1 is removed.

[0036] As a preferred embodiment, based on the above method, a baffle 7 is further provided on the side of the inner wall formwork 4 facing the outer wall formwork 3. The baffle 7 is used to form a groove on the top surface of the concrete structure during concrete pouring. With the ground in the building structure as the projection plane, the length of the longest extension direction of the baffle 7 matches the length of the longest extension direction of the inner wall formwork 4. This structural arrangement can effectively reduce the cost and time of re-plasticizing the concrete after removing the formwork 1.

[0037] Specifically, the baffle 7 can be made of materials such as stainless steel or alloy.

[0038] As a preferred embodiment, based on the above method, the position of the baffle 7 on the inner wall template 4 is further adjustable. This structural arrangement effectively changes the position of the baffle 7 to adapt to the height and spatial arrangement during actual use, further improving the practicality of this invention in practical application.

[0039] Specifically, the baffle 7 can be removed or placed by means of sliding, separating, or snapping.

[0040] As a preferred embodiment, based on the above method, the edge of the inner wall formwork 4 facing the ground is further configured as a curved structure. This structural design effectively reduces the stress on the concrete structure at corners and enhances the stability of the concrete.

[0041] As a preferred embodiment, based on the above method, a support rod 8 is further provided on the side of the inner wall formwork 4 facing the interior of the building structure. The support rod 8 is used to reduce the deformation of the inner wall formwork 4. One side of the support rod 8 is connected to the inner wall formwork 4, and the other side of the support rod 8 is a free end. The free end of the support rod 8 abuts against the floor of the interior of the building structure, and the support rod 8 and the inner wall formwork 4 form an acute angle fit. With this structural arrangement, the stability of the inner wall formwork 4 and the outer wall formwork 3 can be effectively maintained during construction, reducing the deformation of the inner wall formwork 4 and thus the deformation of the concrete structure caused by concrete pouring.

[0042] Specifically, the support rod 8 can be made of high-strength materials such as alloys or steel.

[0043] In Example 3: The flashing base layer and roof structure of this utility model are formed by one-time casting. Based on the above method, the screw 2 further includes a nut 9 and a pipe 10. The nut 9 is used to fix the template 1 and reduce the sliding of the template 1. The pipe 10 is used to connect and cooperate with the nut 9 through the template 1 to keep the outer wall template 3 and the inner wall template 4 at a certain distance.

[0044] In this embodiment, the nut 9 can effectively reduce the slippage of the pipe 10 during construction, thereby reducing the displacement of the screw 2 on the outer wall template 3 and the template 4 and reducing the deformation of the concrete structure.

[0045] Specifically, the nut 9 and the pipe 10 can be made of materials with high hardness, such as stainless steel or steel.

[0046] As a preferred embodiment, based on the above method, the nut 9 and the pipe 10 are further designed to be detachably connected. This structural design allows for the effective installation of the screw 2, and also allows for the replacement of pipes 10 of different lengths to suit actual use, thus improving the practicality of this invention in real-world applications.

[0047] As a preferred embodiment, based on the above method, the nut 9 is further provided with a washer 11. The washer 11 is used to reduce slippage when the nut 9 fixes the pipe 10. The washer 11 is located on the side of the nut 9 facing the pipe 10. With this structural arrangement, when the template 1 is removed and a force is applied to the screw 2, the kinetic energy transmission between the nut 9 and the pipe 10 can be effectively reduced, thereby improving the service life of the screw 2.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
