Description

Technical Field

[0001] This invention relates to the field of building technology, specifically to formwork structures, ground floor structural beams, and their construction methods. Background Technology

[0002] Ground floor structural beams serve to bear the loads of the walls above the beams, transfer the loads from the ground floor slabs, and enhance the overall structural integrity of the building. They are necessary in conventional buildings without basements. When the ground floor elevation is higher than the original ground level and fill is required, there are currently two main construction methods for the ground floor structural beams in the fill area: the first is to erect the beam formwork first and then fill the soil; the second is to fill the soil first, then cut the trench and then build the brick formwork. The scheme most similar to this invention is the first method, where the beam formwork is erected first and then the soil is filled.

[0003] The construction method of first erecting the beam formwork and then backfilling soil follows the sequence of first erecting the beam formwork, then backfilling soil, and finally pouring the structural beam. This method has the following disadvantages: First, the structural beam divides the ground floor into small rectangular or irregular grids, making it impossible to use mechanical backfilling. Manual backfilling is slow, has a long construction period, and low construction efficiency. Second, soil clods are prone to falling into the beam formwork during the backfilling process, making cleaning difficult and failing to guarantee the quality of the ground structural beam. The construction method of setting up formwork before backfilling for ground floor structural beams has the disadvantages of low construction efficiency and poor quality of structural beams. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, a template structure, a ground floor structural beam, and their construction method are provided. This solves the problems of low construction efficiency and excessive manual labor in the construction of ground floor structural beams in embankment areas, and also improves construction quality.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: Firstly, the formwork structure is used in the construction of ground floor structural beams, including standard formwork boxes and formwork box connectors; The standard mold box is a factory component, including a U-shaped mold box bottom mold, a mold box cover plate, and a first sealing element. The mold box bottom mold includes a horizontally arranged mold box bottom plate and mold box wall plates located on both sides of the bottom plate. A mold box tongue and groove for supporting the mold box cover plate is provided on the upper part of the mold box wall plates. The first sealing element is placed in the mold box tongue and groove. The U-shaped mold box bottom mold and the mold box cover plate form a linear cavity structure with openings at both ends. The mold box connector is a factory component, including a connector bottom mold, a connector cover plate, and a second sealing element. The connector bottom mold includes a horizontally arranged connector base plate and connector wall plates located around the base plate. A connector tongue and groove for supporting the mold box cover plate is provided on the upper part of the connector wall plate. The second sealing element is placed inside the connector tongue and groove. A communicating cavity is formed between the connector bottom mold and the connector wall plate, and several intersecting communicating channels are provided in the communicating cavity. The ends of some standard molds are placed in the connecting channel, and the bottom molds of the molds are stacked on the bottom molds of the connectors. The standard molds and the mold connectors constitute the main body of the ground structure beam. Several linear cavity structures are connected through the connecting cavities to form the casting cavity of the ground layer structure beam. The ends of other standard molds are placed on the external foundation.

[0006] According to the above technical solution, it also includes lateral fixing anchors, with several lateral fixing anchors spaced apart on both sides of the standard mold box to support and limit the standard mold box; and at least one lateral fixing anchor between two adjacent connecting channels of the mold box connector to support and limit the mold box connector.

[0007] According to the above technical solution, the length of the standard template end placed on the mold box connector is not less than 200mm.

[0008] According to the above technical solution, the number of the connecting channels is 2, 3, or 4; the connecting cavity is a straight-line structure, a T-shaped structure, or a cross-shaped structure.

[0009] According to the above technical solution, lifting rings are provided on both the mold box cover plate and the connector cover plate.

[0010] According to the above technical solution, it also includes a brick masonry structure, which is set at the end of the standard mold box placed on the external foundation for sealing. If multiple standard molds connected by the mold connector are not at the same height, the standard molds or the mold cover plate can be raised by a brick structure.

[0011] According to the above technical solution, in the same standard mold box, the heights of the mold box wall panels on both sides of the bottom mold of the mold box are the same or different; the heights of the connecting wall panels on the periphery of the same mold box connector are the same or different; and the elevations of multiple standard mold boxes connected by the same mold box connector are the same or different.

[0012] Secondly, the ground floor structural beam includes a template structure as described above, wherein the main body of the ground floor structural beam contains multiple divided rectangular areas; and a first-floor structural slab is set within the rectangular areas as required.

[0013] Thirdly, the construction method for the ground floor structural beams employs a formwork structure as described in any of the above-mentioned methods; the method includes: S1: Site leveling. Before site leveling, there is a pre-constructed external foundation, and the sand and soil bedding layer is used to level the bottom of the mold box and the bottom of the connector mold to the design elevation. S2: Install the template structure according to the design position of the ground floor structural beams; S3: After installing the template structure, fill the soil to the ground level before pouring the ground structure beam; S4: Separate the connector cover plate and the mold box cover plate of the template structure in sequence; S5: After completing the formwork structure, the pouring of concrete forms the ground floor structural beams.

[0014] According to the above technical solution, a first-floor structural slab is installed inside the ground floor structural beam: In step S5, before pouring concrete in the formwork structure, the first layer of structural slab reinforcement is set in the bottom formwork of the standard formwork box and tied to the structural beam reinforcement in the formwork structure; then the concrete is poured. No first-floor structural slab is installed within the ground floor structural beams. In step S5, structural beam reinforcement is installed within the formwork structure; then concrete is poured.

[0015] The present invention has the following beneficial effects: 1. A sealed casting cavity for ground-level structural beams is formed by combining a standard formwork box and its connecting parts with a cover plate and a bottom formwork. During the ground backfilling stage, this facilitates backfilling operations and prevents soil clods from falling into the bottom formwork. During the concrete pouring stage of the structural beams and slabs, the formwork, acting as a structural component, avoids the difficulty of cleaning soil clods from the formwork. This effectively solves the construction problems of ground-level structural beams during backfilling, offering advantages such as simplified procedures, reduced manual labor, increased efficiency, promotion of green and environmentally friendly construction methods, and guaranteed project quality. Furthermore, the modular design meets the construction needs of ground-level structural beams of various specifications, improving construction efficiency and quality while reducing construction costs.

[0016] 2. By using this template structure, after the template structure is installed and before backfilling, the pouring cavity of the ground floor structural beam is sealed by the template cover plate and the connector cover plate. This prevents backfill soil from falling into the pouring cavity during the backfilling process, thus solving the problems of low construction efficiency and excessive manual labor in the construction of the ground floor structural beam in the fill area, and improving the construction quality.

[0017] 3. Install lateral fixing anchors to support and limit the formwork connectors; ensure the construction quality of the ground floor structural beams.

[0018] 4. The length of the precast standard formwork and formwork connectors adopts modular dimensions. The precast standard formwork and precast formwork connectors adopt a nested connection. The nesting of the two can realize any size of the actual beam. By adjusting the nesting length of the two, the same standard formwork can be used for the casting of multiple beams with little variation in length.

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

[0025] Example 1 Reference Figures 1-2 As shown, this invention provides a template structure.

[0026] It is used in the construction of ground floor structural beams and includes standard formwork 1 and formwork connector 2.

[0027] The standard mold is a factory-made component (precast concrete component or steel component), including a U-shaped mold bottom mold 1-1, a mold cover plate 1-2, and a first sealing element 1-3. The mold bottom mold includes a horizontally arranged mold bottom plate 1-11 and mold wall plates 1-12 located on both sides of the bottom plate. A mold tongue and groove 1-13 for supporting the mold cover plate is provided on the upper part of the mold wall plate. The first sealing element is placed in the mold tongue and groove. The U-shaped mold bottom mold and the mold cover plate form a linear cavity structure with openings at both ends. In the above structure, the mold cover plate is placed in the mold tongue and groove of the mold bottom mold, and the mold bottom mold is used to support the mold cover plate.

[0028] The mold box connector is a factory component (precast concrete component or steel component), including a connector bottom mold 2-1, a connector cover plate 2-2, and a second sealing element 2-3. The connector bottom mold includes a horizontally arranged connector base plate 2-11 and a connector wall plate 2-12 located on the periphery of the base plate. A connector tongue and groove 2-13 for supporting the mold box cover plate is provided on the upper part of the connector wall plate. The second sealing element is placed in the connector tongue and groove. A communicating cavity is formed between the connector bottom mold and the connector wall plate, and several intersecting communicating channels are provided in the communicating cavity. In the above structure, the connector cover plate is placed in the mold box tongue and groove of the connector bottom mold, and the connector bottom mold is used to support the connector cover plate.

[0029] The ends of some standard molds are placed in the connecting channel, and the bottom molds of the molds are stacked on the bottom molds of the connectors. The standard molds and the mold connectors constitute the main body of the ground structure beam. Several linear cavity structures are connected through the connecting cavities to form the ground layer structure beam casting cavity. The ends of other standard molds are placed on the external foundation 3.

[0030] In the above structure, modular standard formwork boxes are used as the main formwork for each beam in the ground floor structural beams, and modular formwork box connectors are used as nodes connecting adjacent beams. The standard formwork boxes located on the external foundation serve as support points, supporting the entire ground floor structural beams on the external foundation. Multiple prefabricated standard formwork boxes and multiple prefabricated standard connectors are assembled to form the main body of the ground floor structural beams to meet various design requirements. The main body of the ground floor structural beam contains a casting cavity, within which a reinforcing cage is placed, and then concrete is poured to form a complete ground floor structural beam. After the ground floor structural beams have set, the formwork box covers and connector covers can be recycled and reused.

[0031] Based on the above structure, the cover plate of the standard mold box and the mold box connector are combined with the bottom mold to form a sealed ground floor structural beam casting cavity. During the ground backfilling stage, it can facilitate backfilling operations and prevent soil clods from falling into the bottom mold of the formwork structure. During the concrete pouring stage of the structural beams and slabs, the formwork, as a structural component, can avoid the problem of difficult soil clod removal from the formwork. It can effectively solve the construction problems of ground floor structural beams during backfilling, and has the advantages of simplifying procedures, reducing manual labor, improving efficiency, promoting green and environmentally friendly construction methods, and ensuring project quality.

[0032] Example 2 Based on Example 1, lateral fixing anchors are also included. Several lateral fixing anchors are spaced apart on both sides of the standard mold box to support and limit its movement. At least one lateral fixing anchor 4 is provided between two adjacent connecting channels of the mold box connector to support and limit the connector. The lateral fixing anchors can be made of channel steel, steel pipe, or wooden piles, and are reusable. The lateral fixing anchors are inserted into the soil, with the distance between the bottom end of the anchor and the bottom of the mold box bottom formwork and the bottom of the connector bottom formwork not less than 500 mm. Lateral fixing anchors are centrally located on both sides of the straight connector, three lateral fixing anchors are provided on the side of the T-shaped connector, and four lateral fixing anchors are provided on the side of the cross-shaped connector. Lateral fixing anchors are provided on the sides of the standard mold box, with no fewer than two lateral fixing anchors per standard mold box.

[0033] In Examples 1-2, the prefabricated standard formwork and its connectors are modular in length. The prefabricated standard formwork and connectors are interlocked, allowing for the creation of any actual beam size. Preferably, the end of the standard formwork is positioned at least 200mm above the connector. By adjusting the interlocking length, the same standard formwork can be used for casting multiple beams with similar lengths.

[0034] In embodiments 1-2, the number of connecting channels in a mold box connector is 2, 3, or 4; the connecting cavity is a straight-line structure, a T-shaped structure, or a cross-shaped structure. The straight-line connector is used to connect two standard mold boxes in the same direction, the T-shaped connector is used to connect three standard mold boxes in different directions, and the cross-shaped connector is used to connect four standard mold boxes in different directions.

[0035] In embodiments 1-2, lifting rings 5 ​​are provided on both the mold box cover and the connector cover. During the installation of the mold box cover and the connector cover, as well as during subsequent recycling and reuse, the lifting rings facilitate the hoisting and disassembly of the mold box cover and the connector cover.

[0036] In Examples 1-2, a brick structure 6 is also included, which is used to seal the end of the standard mold placed on the external foundation.

[0037] In Examples 1-2, the heights of the mold wall panels on both sides of the bottom mold of the same standard mold box are the same or different; the heights of the connecting wall panels on the periphery of the same mold box connector are the same or different; and the elevations of multiple standard mold boxes connected by the same mold box connector are the same or different.

[0038] In the above embodiments, In the bottom mold of the connector, the preferred mold box width is the width of the structural beam plus twice the wall plate thickness, and the mold box height is the height of the structural beam plus the bottom plate thickness, or the height of the structural beam minus the thickness of the first-layer structural plate plus the bottom plate thickness. When the heights of the two side wall plates are different, the higher wall plate height is taken as the mold box height of the bottom mold.

[0039] The width and height of the bottom mold are related to the width and height of the structural beams and the thickness of the first-floor structural slab. When designing the first-floor structure, the variety of structural beam sections and structural slab thicknesses should be reduced to improve the prefabrication efficiency of standardized prefabricated molds.

[0040] As shown in the figure, the top of the bottom mold wall panel of the standard mold box is provided with a tongue and groove, the size of which is 60mm*80mm. If the tongue and groove is located in the middle of the wall panel, the size of which is 60mm*100mm, a first sealing element (sealing strip) is provided at the tongue and groove, and the mold box cover is supported by the tongue and groove of the bottom mold wall panel of the mold box.

[0041] The wall thickness of the bottom mold is the same as the bottom plate thickness, determined according to the bottom mold height. When reinforced concrete is used, if the bottom mold height is less than 800mm, the thickness of the bottom plate and wall is 120mm; if the bottom mold height is 800~1500mm, the thickness of the bottom plate and side walls is 150mm; if the bottom mold height is 1500~2000mm, the thickness of the bottom plate and side walls is 180mm.

[0042] If the mold box cover is made of reinforced concrete, the thickness of the plate is 60mm, the width is the width of the structural beam plus 80mm, the mold box cover is equipped with lifting rings, and the number of lifting rings is not less than 2, which can be reused.

[0043] When reinforced concrete is used in the bottom mold of the connector, the tongue and groove size is 80mm*80mm, and a second sealing element (sealing strip) is set at the tongue and groove. The cover plate of the connector is supported by the tongue and groove of the wall panel on the bottom mold of the connector.

[0044] The wall plate and bottom plate of the connector bottom mold have the same thickness, and the wall plate of the mold box bottom mold connected to it has the same thickness; when the wall plate thicknesses of several mold box bottom molds connected to the connector bottom mold are different, the largest wall plate thickness is taken as the wall plate thickness of the connector bottom mold.

[0045] The width of the connector bottom mold is the width of the mold box bottom mold plus twice the thickness of the connector wall plate. When the heights of several mold box bottom molds connected to the connector bottom mold are different, the height of the largest mold box bottom mold plus the thickness of the connector bottom plate is taken as the height of the connector bottom mold. If the connector cover plate is made of reinforced concrete, the plate thickness is 60mm, and the width is the same as the connector bottom mold. The cover plate of the straight connector is rectangular, the cover plate of the T-shaped connector is T-shaped, and the cover plate of the cross-shaped connector is cross-shaped. The cover plate is equipped with lifting rings, with no less than two lifting rings, which can be reused.

[0046] Example 3 The present invention also provides a ground floor structural beam, including a template structure as described above, wherein the main body of the ground structural beam contains a plurality of divided rectangular regions; and a first-floor structural slab is set in the rectangular regions as required.

[0047] Depending on the requirements, a first-floor structural slab can be omitted in all rectangular areas, a first-floor structural slab can be installed in some rectangular areas, or a structural slab can be installed in all areas.

[0048] In a ground-level structural beam where a first-floor structural slab is installed within a partially rectangular area, there may be a beam with a first-floor structural slab on one side and no first-floor structural slab on the other side, which is a soil layer. In this case, the elevation of the first-floor structural slab and the elevation of the soil layer are inconsistent, resulting in inconsistent wall heights on both sides of the bottom mold of the formwork box and on the periphery of the bottom mold of the connector. Preferably, the wall heights of the bottom mold of the formwork box and the bottom mold of the connector are the same when they are in contact.

[0049] Furthermore, due to differences in the building's function and equipment requirements on the first floor, the elevation of the beams (slabs) on the first floor may vary; this may result in multiple standard formworks connected by the same formwork connector having the same or different elevations. For multiple standard formworks connected by the formwork connector that are not at the same height, a brick structure is used to elevate the standard formworks or the formwork cover plates. When elevating the standard formworks, the base plate of the lowest-elevation standard formwork should fit snugly against the base plate of the connector, with the gap between the base plates of the remaining standard formworks and the connector base plates filled by a brick structure.

[0050] Additionally, one end of the structural beam is connected to another structural beam via a formwork connector, while the other end is supported on the external foundation. The end of the standard formwork located on the external foundation can also be supported on the external foundation via a brick masonry structure.

[0051] Example 4 This invention also provides a method for constructing ground floor structural beams, using a formwork structure as described above; the method includes: Transport any of the template structures described above to the designated area.

[0052] S1: Level the site to the elevation of the site before the formwork structure is erected. This elevation is generally about 200mm from the bottom of the formwork box or the bottom of the connector formwork. There is a pre-constructed external foundation before the site is leveled. Afterwards, use a sand cushion layer to level the site to the design elevation of the bottom of the formwork box and the bottom of the connector formwork.

[0053] S2: Install the template structure according to the design position of the ground floor structural beam. Specifically, first place the bottom formwork of the connector; then place the standard formwork box, including the bottom formwork box and the cover plate of the formwork box. The standard formwork box and the formwork box connector are nested together, and the nesting of the two can realize any size of the actual beam; then place the cover plate of the connector; finally, set lateral fixing anchors on the side of the prefabricated standard formwork box and the side of the prefabricated formwork box connector.

[0054] S3: After installing the template structure, fill the soil to the ground level before pouring the ground structure beam; S4: Sequentially lift the connector cover plate and the mold box cover plate of the template structure; use the lifting ring of the connector cover plate to lift the connector cover plate away from the bottom mold of the connector; then, use the lifting ring of the mold box cover plate to lift the mold box cover plate away from the bottom mold of the mold box, and finally remove the set lateral fixing anchor.

[0055] S5: After completing the formwork structure, the pouring of concrete forms the ground floor structural beams.

[0056] Since the ground structure beam is divided into multiple rectangular areas, and the first-floor structural slab may be installed within these rectangular areas, there are two scenarios during the construction process in step S5: The first method involves setting a first-layer structural slab within the ground-level structural beam: In step S5, before pouring concrete within the formwork structure, reinforcement bars for the first-layer structural slab are set within the bottom mold of the standard formwork box and tied to the reinforcement bars of the structural beam within the formwork structure; then, concrete is poured.

[0057] The second scenario involves the absence of a first-floor structural slab within the ground-level structural beam: In step S5, structural beam reinforcement is installed within the formwork structure; followed by concrete pouring.

[0058] In step S2, vertically arranged frame columns 7 are also provided on the external foundation.

[0059] When there is no reinforced concrete slab on the first floor of the building, the standard formwork may not extend to the edge of the column. A brick masonry pad (the above-mentioned brick masonry structure) is used on the shallow foundation or pile cap to the bottom of the standard formwork, and the ends of the standard formwork are sealed with a brick masonry structure.

[0060] When the first floor of the building has a reinforced concrete slab, the standard formwork needs to extend to the edge of the column, and a brick masonry pad (the above-mentioned brick masonry structure) should be used on the shallow foundation or pile cap to the bottom of the standard formwork.

[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
