Description

Technical Field

[0001] This application relates to the field of architecture, specifically to a method and structure for reserving and sealing floor openings, as well as a formwork frame. Background Technology

[0002] With the increasing adoption of pull-tab aluminum alloy formwork, more and more high-rise office buildings and other projects are using aluminum formwork. However, due to the construction requirements of high-rise buildings, a large opening must be reserved during the floor slab pouring to install large equipment such as tower cranes or concrete placing booms, and then the opening is sealed with cement later. In the traditional method, wooden formwork is usually installed directly on the bottom of the floor slab to seal the opening, and then cement is poured to fill the opening. However, this method has the disadvantages of low formwork installation efficiency and difficulty in controlling the dimensional accuracy of the formwork to match the size of the opening. In addition, the cement interception at the opening in the traditional sealing method requires special treatment with wire mesh, resulting in low work efficiency. Summary of the Invention

[0003] In view of this, it is necessary to provide a method and structure for reserving and sealing floor openings, as well as a formwork frame, in order to improve the installation efficiency of the formwork, improve dimensional accuracy, and avoid additional special treatment, thereby improving work efficiency.

[0004] One embodiment of this application provides a method for reserving and sealing floor openings, including:

[0005] Multiple first-plane templates are supported to the floor level by multiple first-support rods. The panels of the multiple first-plane templates face upward and are horizontally spliced ​​together to form a casting plane with openings.

[0006] Multiple transition templates are spliced ​​together along the edge of the opening onto the first plane template. Each transition template has a stop surface on the side away from the opening, and the stop surface is perpendicular to the pouring plane.

[0007] The embedded component is installed on the transition template. The embedded component includes a threaded embedded sleeve and a screw. The embedded sleeve is located on the side of the stop surface away from the opening, and the screw passes through the stop surface.

[0008] Multiple steel bars are laid horizontally above the pouring surface, and the steel bars extending to the stop surface are bent upwards.

[0009] Pour cement above the pouring surface until the cement submerges the horizontal reinforcing bars and embedded sleeves. The stop surface can prevent cement from entering the opening, so that the cement solidifies to form a floor with the opening.

[0010] Remove the first support rod and the first plane formwork, and retain the transition formwork and the embedded components. The embedded components are used to maintain the connection between the transition formwork and the floor.

[0011] After the opening is used up, multiple second plane templates are supported by multiple second support rods. The multiple second plane templates are spliced ​​together and connected to the transition template, so that the top surfaces of the second plane templates and the transition template together form a sealing plane to fill the opening.

[0012] Remove the bolts to disconnect the formwork from the floor slab;

[0013] Adjust the height of the second support rod so that the second plane template and the transition template are lowered together until the sealing plane is flush with the bottom surface of the floor.

[0014] Adjust the bent steel bar to fit into the opening, and pour cement into the opening. The sealing surface should be able to support the cement inside the opening. After the cement hardens, seal the opening to ensure the floor remains intact.

[0015] Remove the second support rod, the adapter plate, and the second plane template.

[0016] The method for reserving and sealing floor openings provided in this case involves pre-installing a transition template at the floor opening. This not only does not affect the reservation and use of the opening, but also allows the second plane template to be directly installed onto the transition template when sealing the opening later. This improves the installation efficiency and precision control of the second plane template, while avoiding additional special treatment, thereby improving the overall efficiency of the operation.

[0017] One embodiment of this application also provides a structure for reserving and sealing a floor opening, including multiple first planar templates, transition templates, embedded components, reinforcing bars, second planar templates, and support rods. Multiple first planar templates are joined together horizontally with their surfaces facing upwards to form a pouring plane with an opening. Multiple transition templates are joined together along the edge of the opening and connected to the first planar templates. Each transition template has a stop surface on the side opposite to the opening, and the stop surface is perpendicularly connected to the pouring plane. The embedded component includes a threaded embedded sleeve and a threaded rod. The embedded sleeve is located on the side of the stop surface opposite to the opening, and the threaded rod passes through the stop surface. Multiple reinforcing bars are distributed above the pouring plane and parallel to the pouring plane. The reinforcing bars can be bent upwards along the stop surface. Multiple second planar templates are joined together horizontally with their surfaces facing upwards to the inside of the transition templates to form a sealing plane with the same area as the opening. Multiple support rods can support the first and second planar templates and can adjust the height of the second planar templates.

[0018] In some embodiments, each transition template also has a horizontal pouring surface and a vertical connecting surface. The horizontal pouring surface is vertically connected to the side of the stop surface facing the opening, and the vertical connecting surface is connected to the bottom of the horizontal pouring surface. The vertical connecting surface is used to connect the side wall of the second planar template. The plate surface of the second planar template is flush with the horizontal pouring surface to jointly form a sealing plane.

[0019] In some embodiments, each transition template is provided with sealing plates at both ends, and the sealing plates are vertically connected to the stop surface, the horizontal pouring surface and the vertical connection surface.

[0020] In some embodiments, the stop surface is provided with a first connecting hole and a through hole. The first connecting hole is used to align with the hole on the side wall of the first flat template to connect the adapter template to the first flat template. The through hole is used to pass through the screw. The vertical connecting surface is provided with a second connecting hole. The second connecting hole is used to align with the hole on the side wall of the second flat template to connect the second flat template to the adapter template. The sealing plate is provided with a third connecting hole to connect the adjacent adapter template.

[0021] In some embodiments, the length of the adapter template extends in a straight line or at a right angle to block the rectangular opening.

[0022] In some embodiments, the end of the screw away from the pre-embedded sleeve has a pull ring.

[0023] In some embodiments, the embedded component further includes a gasket through which the screw passes, and the gasket is located between the pull ring and the adapter template.

[0024] In some embodiments, the stop surface is provided with a plurality of clearance grooves, which are arranged vertically, and each clearance groove is used to accommodate a bent portion of a steel bar.

[0025] In one embodiment of this application, a template frame is also provided, including a wall template and a reserved and sealed structure for floor openings in any of the above embodiments. The wall template is vertically set for casting vertical walls, and a first plane template is connected to the wall template.

[0026] The template frame provided in this case also achieves the purpose of improving the efficiency of reserving and sealing floor openings through the aforementioned floor opening reservation and sealing structure. Attached Figure Description

The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0074] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0075] This application embodiment provides a structure 100 for reserving and sealing floor openings, such as... Figures 1 to 18 This structure is used to pre-leave an opening 300 during the pouring of floor slab 200, and then seal the opening 300 later to restore the complete floor slab 200. The pre-leave and sealing structure 100 for the floor opening includes multiple first support rods 10, first plane templates 20, transition templates 30, embedded components 40, reinforcing bars 50, second plane templates 60, and second support rods 70. The multiple first plane templates 10 are used to splice together horizontally to form a pouring plane A with an opening. The multiple transition templates 30 can be spliced ​​together along the edge of the opening 300 and connected to the first plane templates 20. Each transition template 30 has a stop surface 31 on the side opposite to the opening 300, and the stop surface 31 is perpendicular to the pouring plane A. The embedded component 40 includes a threaded embedded sleeve 41 and a screw 42. The embedded sleeve 41 is located on the side of the stop surface 31 facing away from the opening 300 and is used to be embedded in the floor 200. The screw 42 passes through the stop surface 31 and connects to the embedded sleeve 41. The reinforcing bars 50 can be vertically and alternately distributed above the pouring plane A and parallel to the pouring plane A. The reinforcing bars 50 can be vertically bent upward along the stop surface 31 where they are blocked. Multiple second plane templates 60 are used to splice together horizontally inside the transition template 30. The top surfaces of the second plane templates 60 and the transition template 30 together form a sealing plane B with the same area as the opening 300. The first support rod 10 and the second support rod 70 can support the first plane template 20 and the second plane template 60 and can adjust the height of the first plane template 20 and the second plane template 60.

[0076] This application also provides a method for reserving and sealing floor openings, such as... Figure 19 This is used to create and seal floor openings through a pre-installed opening structure 100, allowing for the creation of an opening 300 during the pouring of the floor slab 200, followed by sealing the opening 300 to restore the complete floor slab 200. Methods for pre-installing and sealing floor openings include:

[0077] S1: As Figure 1 or Figure 10 Multiple first support rods 10 support multiple first flat templates 20 to the required height of the bottom surface of the floor to be poured. The multiple first flat templates 20 are used for pouring with the slab surface facing upward and spliced ​​together in the horizontal direction to form a pouring plane A with an opening 300.

[0078] S2: As Figure 2 or Figure 11 Multiple transition templates 30 are connected to the first plane template 20 along the edge of the opening 300, and multiple transition templates 30 are spliced ​​around the opening 300. Each transition template 30 has a stop surface 31 on the side away from the opening 300, and the stop surface 31 is perpendicular to the pouring plane A.

[0079] S3: As Figure 2 or Figure 11 The pre-embedded component 40 is installed on the stop surface 31 of the adapter template 30. The pre-embedded component 40 includes a threaded pre-embedded sleeve 41 and a screw 42. The pre-embedded sleeve 41 is located on the side of the stop surface 31 away from the opening 300. One end of the screw 42 passes through the stop surface 31 and extends into the pre-embedded sleeve 41, and the other end is located on the side of the stop surface 31 facing the opening 300.

[0080] S4: As Figure 3 or Figure 12 Multiple steel bars 50 are laid horizontally and tied above the pouring plane A. The multiple steel bars 50 are staggered, and the steel bars 50 extending to the stop surface 31 are bent vertically upward along the stop surface 31. That is, the part of the steel bar 50 blocked by the stop surface 31 is bent upward close to the stop surface 31.

[0081] S5: As Figure 4 or Figure 13 Cement is poured above the pouring plane A until it submerges the horizontal steel bar 50 and the embedded sleeve 41. The stop surface 31 can prevent cement from entering the opening 300, so that the cement solidifies to form a floor 200 with the opening 300.

[0082] S6: As Figure 14Remove the first support rod 10 and the first flat template 20, and retain the transition template 30 and the embedded component 40. The embedded component 40 is used to maintain the connection between the transition template 30 and the floor 20, and to prevent the transition template 30 from falling off the floor 20 when the opening 300 is used.

[0083] S7: As Figure 5 or Figure 15 After the opening 300 is used, multiple second plane templates 60 are supported by multiple second support rods 70. The multiple second plane templates 60 are spliced ​​together and connected to the transition template 30, so that the top surface of the second plane templates 60 and the transition template 30 together form a sealing plane B to fill the opening 300.

[0084] S8: As Figure 15 Remove screw 42 to disconnect the connection between the transfer template 30 and the floor 200, and leave the embedded sleeve 41 inside the floor 200;

[0085] S9: such as Figure 6 or Figure 16 Adjust the height of the second support rod 70 so that the second plane template 60 and the transition template 30 are lowered together until the sealing plane B is flush with the bottom surface of the floor 200, that is, the sealing plane B coincides with the pouring plane A, that is, the sealing plane B and the pouring plane A are located on the same plane within a certain error range.

[0086] S10: As Figure 6 or Figure 16 The vertically bent steel bar 50 is leveled within the opening 300, and cement is poured into the opening 300. The sealing plane B can support the cement within the opening 300. After the cement hardens, the opening 300 is sealed to ensure the integrity of the floor 200. Figure 17 ;and

[0087] S11: As Figure 18 Remove the second support rod 70, the adapter plate 30, and the second plane template 60.

[0088] It is understandable that the order of S2 and S3 can be reversed, that is, the pre-embedded component 40 is installed onto the adapter template 30 first, and then the adapter template 30 is installed onto the first plane template 20.

[0089] Furthermore, the vertical bend of the reinforcing bar 50 refers to a portion that is close to vertical within a certain error range. This vertical bend facilitates subsequent leveling of the reinforcing bar 50 and prevents it from becoming trapped in the cement. In other embodiments, the bend of the reinforcing bar 50 can also be inclined. If, during subsequent leveling, the bent reinforcing bar 50 becomes trapped in the solidified cement, it can be leveled by chiseling out the cement. Finally, the chiseled cement is filled by pouring water through the opening 300, thus completing the floor 200.

[0090] The reserved and sealed structure 100 for floor openings and its method pre-prepared a transition template 30 at the opening 300. This not only does not affect the use of the opening 300, but also allows the second plane template 60 to be directly installed onto the transition template 30 when sealing the opening 300 later. This improves the ease and efficiency of installing the second plane template 60, and also allows for precise control of the installation accuracy of the second plane template 60. Compared with the traditional method of not pre-installing the transition template 30, the method of this invention can precisely control the required quantity and size of the second plane template 60 to fill the opening 300. Furthermore, the sealing plane B formed by the second plane template 60 and the transition template 30 can also accurately match the size of the opening 300. By moving the sealing plane B downward, the number of second plane templates 60 used is not wasted, reducing unnecessary labor costs. At the same time, compared with the traditional method, the method of this invention also avoids the use of additional special treatments such as wire mesh, thereby improving the overall efficiency of the operation.

[0091] As an example, the first support rod 10 and the second support rod 70 have the same structure, the first plane template 20 and the second plane template 60 have the same structure, and include templates of different sizes, such as top support templates, keel templates and face templates. The first support rod 10 and the second support rod 70 support the top support template. The two ends of the keel template are connected to the top support template to form a skeleton. The face template fills the spaces between the multiple skeletons, thereby forming the entire pouring plane A or sealing plane B.

[0092] Please see Figure 7 and Figure 8 In some embodiments, each transition template 30 also has a horizontal pouring surface 32 and a vertical connecting surface 33. The horizontal pouring surface 32 is vertically connected to the side of the stop surface 31 facing the opening 300, and the vertical connecting surface 33 is vertically connected to the bottom of the horizontal pouring surface 32. The vertical connecting surface 33 is used to connect the side wall of the second planar template 60. The plate surface of the second planar template 60 is flush with the horizontal pouring surface 32 to jointly form the sealing plane B. That is, the sealing plane B is composed of the horizontal pouring surface 32 and the top surface of the second planar template 60.

[0093] Furthermore, each transition template 30 is provided with a sealing plate 34 at both ends. The sealing plate 34 is vertically connected to the stop surface 31, the horizontal pouring surface 32 and the vertical connecting surface 33. The sealing plate 34 is used to connect adjacent transition templates 30 and can also serve as a reinforcing rib to strengthen the transition template 30.

[0094] Furthermore, the stop surface 31 is provided with a plurality of arranged first connecting holes 31a and through holes 31b. The first connecting holes 31a are used to align with the holes on the side wall of the first flat template 20 to connect the adapter template 30 to the first flat template 20, and the through holes 31b are used to receive the screw 42. The vertical connecting surface 33 is provided with a second connecting hole 33a, which is used to align with the holes on the side wall of the second flat template 60 to connect the second flat template 60 to the adapter template 30. The sealing plate 34 is provided with a third connecting hole 34a to connect adjacent adapter templates 30. As an exemplary example, the templates are connected to each other by pins and tabs.

[0095] In some embodiments, the length of the transition template 30 extends in a straight line and at right angles to block the rectangular opening 300, wherein it is understood that there are four right-angled transition templates 30.

[0096] Please see Figure 9 In some embodiments, the end of the screw 42 away from the pre-embedded sleeve 41 has a pull ring 42a, which facilitates the rotation of the screw 42 by means of tools such as a pry bar.

[0097] Furthermore, the pre-embedded component 40 also includes a gasket 43, through which the screw 42 passes. The gasket 43 is located between the pull ring 42a and the adapter template 30. The gasket 43 is used to increase the contact area between the screw 42 and the adapter template 30. The pull ring 42a presses the adapter template 30 by pressing against the gasket 43, thereby increasing the friction between the screw 42 and the adapter template 30 and improving the stability of the adapter template 30.

[0098] In some embodiments, the stop surface 31 may be provided with multiple clearance grooves (not shown). The clearance grooves are vertically arranged and penetrate through the top of the transition template 30. Each clearance groove is used to accommodate a vertically bent part of a steel bar 50 to prevent the bent part of the steel bar 50 from immersing in the cement, thereby facilitating the straightening of the steel bar 50 when filling the opening 300 later.

[0099] This application also provides a template frame (not shown in the figure), including a wall template and a reserved and sealed structure 100 for floor openings. The wall template is set vertically and used to cast vertical walls. The first plane template 20 is vertically connected to the wall template. The floor 200 formed by the reserved and sealed structure 100 for floor openings is connected to the wall to form a building structure.

[0100] The template frame provided in this case also achieves the purpose of improving the efficiency and accuracy of reserving and sealing the 300mm opening through the aforementioned floor opening reservation and sealing structure.

[0101] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
