Description

Technical Field

[0001] This utility model relates to the field of building formwork construction technology, specifically to a building formwork fixing structure. Background Technology

[0002] In building construction, formwork fixing structures are used to fix the spatial position of formwork (such as elevation, verticality, cross-sectional dimensions, etc.), ensuring that concrete components meet design requirements, bearing the weight of the formwork itself, the weight of the concrete, construction loads (such as the weight of personnel and equipment), and the lateral pressure during concrete pouring, preventing the formwork from deforming, displacing, or collapsing during the pouring process, and ensuring the safety of construction personnel and the structure.

[0003] Chinese patent discloses a building formwork fixing structure (publication number CN222759376 U). This patented technology fixes double-channel steel to the building formwork with tie bolts, so that the double-channel steel and the building formwork are closely fitted. This allows the pressure on the formwork generated by pouring concrete to be transferred to the double-channel steel through the building formwork. The double-channel steel improves the overall strength of the building formwork fixing. However, double-channel steel is a heavy steel material, and its self-weight is significantly higher than that of traditional timber or single-channel steel keel, which increases the overall load of the support system, increases the construction difficulty and safety risks. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A formwork fixing structure for construction includes:

[0006] Four back plates are symmetrically distributed on the left and right sides. A support mechanism is provided on the back side of the pair of back plates on the right side. U-shaped frames are connected to the upper and lower positions of the front side of the pair of back plates. An aluminum alloy back rib is connected to the inner side of the U-shaped frame. Several first through holes are opened horizontally on the top of the aluminum alloy back rib. An elongated hole is opened on one side of the aluminum alloy back rib. Four tie bolts are connected horizontally inside the elongated hole.

[0007] In one possible implementation, the support mechanism includes a second hinge seat, inside which a support sleeve and a second support rod are respectively connected. A base plate is connected to the bottom of the second hinge seat. A first support rod is slidably connected inside the support sleeve. One end of the first support rod is rotatably connected to the back plate, and one end of the second support rod is rotatably connected to the back plate.

[0008] In one possible implementation, the back plate, the first support rod, the support sleeve, and the second support rod are arranged in a triangular pattern.

[0009] In one possible implementation, the back side of the back plate is connected from top to bottom to a first hinge seat and a third hinge seat, the first hinge seat being rotatably connected to a first support rod, and the third hinge seat being rotatably connected to a second support rod.

[0010] In one possible implementation, the end of the support sleeve is provided with a pair of third through holes, and a second bolt connection is connected through the interior of the third through holes. The bottom of the first support rod is provided with a plurality of fourth through holes, and the second bolt connection penetrates the interior of the fourth through holes.

[0011] In one possible implementation, the U-shaped frame has second through holes on both the upper and lower sides, and a first bolt connection is connected through the interior of the second through hole, with the first bolt connection penetrating the interior of the first through hole.

[0012] In one possible implementation, the base plate has a pair of mounting holes inside, and an anchor pile is connected through the mounting holes.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] By using aluminum alloy back ribs, the weight is reduced compared to double-channel steel, while maintaining the same strength. The aluminum alloy back ribs on both sides are fixed to the building formwork using tie bolts. A back plate is then installed on the back side of the aluminum alloy back ribs, and a first support rod, a support sleeve, the back plate, and a second support rod are arranged in a triangular configuration on the back side of the back plate. The bottom plate is then fixed with a pair of anchor piles, resulting in a stable triangular arrangement between the back plate, the first support rod, the support sleeve, the back plate, and the second support rod. This converts the horizontal lateral pressure of the poured concrete and the self-weight of the back ribs into the axial force of the support rods. The load is transferred bidirectionally through the support sleeve, avoiding single-point stress and greatly improving stability. Attached Figure Description

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] This application provides a building formwork fixing structure to solve the problems in the prior art.

[0023] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0024] like Figures 1-3 As shown, a building formwork fixing structure includes:

[0025] Four back plates 7 are symmetrically distributed on the left and right sides. A support mechanism is provided on the back side of the pair of back plates 7 on the right side. U-shaped frames 13 are connected to the upper and lower positions of the front side of the pair of back plates 7. An aluminum alloy back rib 3 is connected to the inner side of the U-shaped frame 13. Several first through holes 1 are opened horizontally on the top of the aluminum alloy back rib 3. An elongated hole 4 is opened on one side of the aluminum alloy back rib 3. Four tie bolt connecting pairs 2 are horizontally connected inside the elongated hole 4.

[0026] In some examples, the support mechanism includes a second hinge seat 16, inside which a support sleeve 6 and a second support rod 8 are respectively connected. The bottom of the second hinge seat 16 is connected to a base plate 9. The support sleeve 6 is slidably connected to a first support rod 5. One end of the first support rod 5 is rotatably connected to a back plate 7, and one end of the second support rod 8 is rotatably connected to the back plate 7. The first support rod 5, the support sleeve 6, the back plate 7, and the second support rod 8 are arranged in a triangle. The base plate 9 is then fixed by a pair of anchor piles 10, so that the back plate 7, the first support rod 5, the support sleeve 6, the back plate 7, and the second support rod 8 are arranged in a stable triangle. The horizontal lateral pressure of the concrete pouring and the self-weight of the back rib are converted into the axial force of the support rod. The load is transferred bidirectionally through the support sleeve 6, avoiding single-point stress and greatly improving stability.

[0027] In some examples, the back plate 7, the first support rod 5, the support sleeve 6, and the second support rod 8 are arranged in a triangle to further improve the stability between the back plate 7, the first support rod 5, the support sleeve 6, and the second support rod 8.

[0028] In some examples, the back side of the back plate 7 is connected from top to bottom to a first hinge seat 14 and a third hinge seat 17. The first hinge seat 14 is rotatably connected to the first support rod 5, and the third hinge seat 17 is rotatably connected to the second support rod 8. By setting the first hinge seat 14 and the third hinge seat 17, the angles of the first support rod 5, the support sleeve 6 and the second support rod 8 can be flexibly adjusted.

[0029] In some examples, the end of the support sleeve 6 is provided with a pair of third through holes 18, and the interior of the third through holes 18 is connected by a second bolt connection pair 15. The bottom of the first support rod 5 is provided with several fourth through holes 19, and the second bolt connection pair 15 passes through the interior of the fourth through holes 19. By removing the second bolt connection pair 15, the distance between the support sleeve 6 and the first support rod 5 can be adjusted.

[0030] In some examples, the upper and lower sides of the U-shaped frame 13 are provided with second through holes 12, and a first bolt connection pair 11 is connected through the interior of the second through hole 12. The first bolt connection pair 11 passes through the interior of the first through hole 1. By inserting the first bolt connection pair 11 into the interior of the second through hole 12 and the first through hole 1, it is convenient to fix the U-shaped frame 13 and the aluminum alloy back rib 3.

[0031] In some examples, a pair of mounting holes 20 are provided inside the base plate 9, and an anchor pile 10 is connected through the mounting holes 20. By setting the anchor pile 10, it is convenient to fix the base plate 9.

[0032] This invention reduces weight compared to double-channel steel by using aluminum alloy back ribs 3, while maintaining the same strength. The aluminum alloy back ribs 3 on both sides are fixed to the building formwork using tie bolts 2. A back plate 7 is then installed on the back side of the aluminum alloy back ribs 3, and a first support rod 5, a support sleeve 6, the back plate 7, and a second support rod 8 are arranged in a triangular configuration on the back side of the back plate 7. A pair of anchor piles 10 then fix the base plate 9, ensuring a stable triangular arrangement between the back plate 7, the first support rod 5, the support sleeve 6, the back plate 7, and the second support rod 8. This converts the horizontal lateral pressure of the poured concrete and the self-weight of the back ribs into the axial force of the support rods. The support sleeve 6 enables bidirectional load transfer, avoiding single-point stress and significantly improving stability.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
