Description

Technical Field

[0001] This utility model belongs to the field of casting formwork technology, specifically relating to a casting formwork structure for the top slab of a sandwich space. Background Technology

[0002] In existing building structures, basements need to withstand various loads from the soil, moisture, and ground activity above. Therefore, some basement roofs are designed as mezzanine (double-layer) structures. By increasing the number of slabs, these loads can be effectively distributed, and the load-bearing capacity of the roof slab can be improved.

[0003] Existing mezzanine roof slabs are usually poured sequentially from bottom to top. However, when pouring the top slab, since the bottom slab and the side walls of the mezzanine structure have already been poured, the formwork for the top slab that is set on the bottom slab cannot be disassembled and removed after the top slab is poured. This results in a waste of the formwork structure, that is, the reuse rate of the formwork is low, which increases the construction cost and is not conducive to practical use. Utility Model Content

[0004] The present invention aims to provide a formwork structure for casting the top slab of a mezzanine space, so as to solve the problem of low reuse rate of existing casting formwork used in the casting of mezzanine top slabs mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a formwork support structure for casting the top slab of a mezzanine space, comprising...

[0006] The enclosure module includes multiple vertically arranged enclosure panels, which are spliced ​​together and the overall cross-sectional shape of the enclosure panels is square. The side walls of the enclosure panels are provided with clearance holes.

[0007] The base plate module includes multiple horizontally arranged base templates. The lower end of the outer wall of the enclosure panel is provided with a base template, and the multiple base templates are spliced ​​together in sequence.

[0008] Support components are used to support the enclosure panels and the bottom formwork;

[0009] The reinforcement module is installed on the bottom template.

[0010] The principle and effects of this technical solution:

[0011] 1. By combining the bottom formwork and the retaining panel, the retaining panel can separate a portion of the area without the bottom formwork, and the retaining panel forms the pouring side panel. This allows the area outside the retaining panel to be poured first when pouring the top slab. After the top slab is poured, the bottom formwork and its corresponding support components can be disassembled and removed through the inside of the retaining panel into the mezzanine area. Then, the retaining panel is removed, and the bottom formwork is set at the retaining panel location for pouring. This improves the reusability of the support components and the bottom formwork, maximizes the recycling of parts, and reduces costs.

[0012] 2. By strengthening the module settings, the pouring strength will not be affected by the inability to install steel mesh at the retaining module. Furthermore, the setting of clearance holes on the retaining plate allows the steel bars to pass through the clearance holes, thereby improving the pouring strength of the inner side of the post-poured retaining plate.

[0013] The present invention is further configured as follows: the reinforcing module includes a vertical reinforcing cage, a horizontal reinforcing cage, and multiple vertically arranged column templates. The multiple column templates are spliced ​​together and set at the bottom of the bottom template and the cladding plate. The overall cross-sectional shape of the multiple column templates is square. The vertical reinforcing cage is set inside the column template, and the top of the vertical reinforcing cage extends to the top of the bottom template. The horizontal reinforcing cage is set on the bottom template and connected to the vertical reinforcing cage. The cladding plate is located inside the horizontal reinforcing cage. The support component is also used to support the column template.

[0014] The principle and effect of this technical solution: By closing and limiting the vertical steel reinforcement cage through the column formwork, the vertical steel reinforcement cage can be integrally formed with the pre-cast top slab. At the same time, the vertical steel reinforcement cage can provide support, and the horizontal steel reinforcement cage can be connected and threaded through the surrounding steel mesh. This does not affect the casting strength of the top slab outside the retaining panel. In other words, after the vertical and horizontal steel reinforcement cages are cast, they act as beams and columns, thus overcoming the problem that the inability to set steel mesh on the inside of the retaining panel affects the casting strength of the top slab. Furthermore, when the inside of the retaining panel is cast after its removal, by connecting the steel mesh with the steel bars extending outside the clearance holes and coordinating with the support components, the impact on the casting strength of the inside of the retaining panel can be reduced.

[0015] The present invention is further configured such that: the support assembly includes vertical struts, diagonal struts, scaffolding, diagonal braces, and horizontal braces; the scaffolding is set below the retaining panel, and the projection of the scaffolding on the horizontal plane is located inside the projection of the retaining panel on the horizontal plane; one end of the diagonal brace is connected to the scaffolding, and the other end of the diagonal brace is connected to the inner wall of the retaining panel; vertical struts are installed on the bottom surface of the bottom formwork; the column formwork on the side closest to the scaffolding is connected to the scaffolding through horizontal braces; and diagonal struts are installed on the outer wall of the remaining column formwork.

[0016] The principle and effect of this technical solution: By supporting the bottom formwork with vertical braces, supporting the column formwork away from the scaffolding with diagonal braces, supporting the retaining panels with scaffolding and diagonal braces, and supporting the column formwork on the side close to the scaffolding with scaffolding and horizontal braces, each formwork component can be supported and stabilized. In addition, the scaffolding can also act as a ladder, making it convenient for workers to climb into and out of the mezzanine.

[0017] The present invention is further configured to include a protective component, which includes a protective plate disposed on the top of the scaffolding, the protective plate being located inside the enclosure panel.

[0018] The principle and effect of this technical solution: By setting up the protective plate, the steel bars extending outside the clearance hole and into the inner side of the retaining plate can be isolated, so as to avoid the workers being obstructed by the steel bars when climbing into and out of the inner side of the retaining plate. At the same time, it can also isolate the bottom formwork and support components from the steel bars, which is conducive to the workers' disassembly and assembly of tools and entry and exit from the mezzanine.

[0019] The present invention is further configured such that: a horizontally arranged steel pipe is pre-embedded in the horizontal steel reinforcement cage, and the steel pipe abuts against the outer wall of the enclosure panel.

[0020] The principle and effect of this technical solution: The steel pipe allows the device to arrange a steel mesh in the un-poured (post-poured) area inside the retaining wall when pouring the inner area of ​​the retaining wall. This maximizes the pouring strength of the area and ensures its reliability, without having to destroy the horizontal steel cage area after pouring by drilling.

[0021] The present invention is further configured such that a baffle is installed on the top surface of both the protective plate and the enclosure plate.

[0022] The principle and effect of this technical solution: The baffle can prevent concrete from spilling during pouring, and can also protect and shield workers when they enter or exit the inside of the enclosure and pass out parts and tools.

[0023] The present invention is further configured such that the length of the bottom template is different from the width of the bottom template.

[0024] The principle and effect of this technical solution: By making the length and width of the bottom template different, the square formed by the enclosure module is made into a rectangle, so that the bottom template can be removed vertically from the inside of the enclosure panel, and it is easier to remove than a square.

[0039] Example:

[0040] As attached Figure 1-6 As shown, this utility model discloses a formwork structure for casting the top slab of a mezzanine space, which is set on the bottom top slab 610. The side walls of the basement and the bottom top slab 610 are cast first. The formwork structure for casting the top slab of a mezzanine space includes an enclosure module, a bottom slab module, a support component, a reinforcing module, and a protective component. The enclosure module includes multiple vertically arranged enclosure panels 110. The multiple enclosure panels 110 are spliced ​​together, and the overall cross-sectional shape of the multiple enclosure panels 110 is square. The side walls of the enclosure panels 110 are provided with clearance holes 111. In this solution, four enclosure panels 110 are used as an example, and the four enclosure panels 110 form a cuboid shape.

[0041] The base slab module includes multiple horizontally arranged base formwork pieces 210. The outermost base formwork piece 210 abuts against the side wall of the basement, and the innermost base formwork piece 210 is spliced ​​to the lower end of the outer wall of the retaining panel 110. The retaining panel is located in the middle of the base formwork piece 210 group, and the length and width of the base formwork piece 210 are not the same.

[0042] The reinforcing module includes a vertical reinforcing cage 310, a horizontal reinforcing cage 320, and multiple vertically arranged column formwork 330s. The multiple column formwork 330s are spliced ​​together and set at the bottom of the bottom formwork 210 and the retaining plate 110. The bottom surface of the column formwork 330 is connected to the top surface of the bottom top plate 610. The overall cross-sectional shape of the multiple column formwork 330s is square. The vertical reinforcing cage 310 is set inside the column formwork 330, and the top of the vertical reinforcing cage 310 extends to the top of the bottom formwork 210. The bottom of the vertical reinforcing cage 310 can be installed on the top surface of the bottom top plate 610 by welding or other means. The horizontal reinforcing cage 320 is set on the bottom formwork 210 and connected to the vertical reinforcing cage 310. The retaining plate 110 is located inside the horizontal reinforcing cage 320.

[0043] The support components include vertical struts 410, diagonal struts 420, scaffolding 430, diagonal braces 440, and horizontal braces 450. Scaffolding 430 is located below the retaining plate 110, and the projection of scaffolding 430 on the horizontal plane is located inside the projection of retaining plate 110 on the horizontal plane. One end of diagonal brace 440 is connected to scaffolding 430, and the other end of diagonal brace 440 is connected to the inner wall of retaining plate 110. Vertical struts 410 are installed on the bottom surface of bottom formwork 210. Column formwork 330 near scaffolding 430 is connected to scaffolding 430 through horizontal braces 450. Diagonal struts 420 are installed on the outer wall of the remaining column formwork 330. The shape of scaffolding 430 corresponds to the square shape formed by retaining plate 110. Horizontally arranged steel pipes are pre-embedded in the horizontal steel cage 320, and the steel pipes abut against the outer wall of retaining plate 110.

[0044] The protective assembly includes a protective plate 510 installed on the top of the scaffold 430. The protective plate 510 is located inside the enclosure 110, and a baffle 520 is installed on the top surface of the protective plate 510 and the enclosure 110.

[0045] In use, first install the enclosure module, base plate module, support components, reinforcing modules, and protective components. Then, a steel mesh needs to be installed on the base formwork 210. The ends of the steel mesh can be connected to the steel mesh at the top of the basement side wall or to the horizontal steel cage 320, depending on the location. Then, the area above the base formwork 210 is poured and formed. Before pouring, the clearance holes 111 and the steel pipes need to be sealed with water-stopping components such as water-stopping plugs and water-stopping rings. After the concrete above the base formwork 210 has solidified, workers enter the mezzanine area through the inside of the enclosure plate 110 to install the vertical struts 410, diagonal struts 420, column formwork 330, and diagonal struts 420. The poles 440, crossbars 450, and retaining panels 110 are disassembled and removed, leaving only the scaffolding 430 in the mezzanine. Workers then leave the mezzanine area and install the bottom formwork 210 on the scaffolding 430, sealing the bottom formwork 210 with the previously poured concrete area. The water-stopping components inside the steel pipes are then removed, and steel bars are inserted into the steel pipes to create a steel mesh in the area corresponding to the retaining panels 110. After the steel mesh is in place, concrete is poured into the area to complete the final molding. During this process, only the support components below the retaining panels 110 cannot be removed; all other support components can be removed, resulting in a high recycling and reuse rate.
