Description

Technical Field

[0001] This utility model relates to the field of concrete molds, specifically to a precast concrete assembled retaining wall mold. Background Technology

[0002] In manually excavated bored pile construction, the retaining wall is a crucial structure for ensuring the safety of pile foundation construction and the stability of the borehole. Traditional retaining wall construction often employs on-site concrete pouring, a method with drawbacks such as cumbersome procedures, long construction cycles, low efficiency, susceptibility to environmental influences, and difficulty in controlling precision and quality. Therefore, precast concrete assembled retaining walls are needed. However, current molds used for pouring precast concrete assembled retaining walls have several shortcomings. Firstly, traditional molds often use integral welded structures lacking modular design; a single mold can only produce a single specification of retaining wall segment, requiring new molds for each new project, resulting in low mold reuse rates. Furthermore, the integral molds are difficult to dismantle, requiring forceful hammering that can easily damage the edges and corners of the retaining wall segments. Secondly, traditional molds often lack a base or use a low-profile base, making them prone to deformation during concrete pouring. This also forces workers to frequently bend over, increasing their labor intensity. In addition, traditional molds lack an integrated positioning system; bolt holes must be marked and positioned by workers before drilling, which not only lengthens the construction cycle but also easily causes significant deviations and can damage the retaining wall segments during drilling.

[0003] Therefore, there is an urgent need for a new type of precast concrete assembly wall mold that can be used for multiple purposes, is easy to disassemble, reduces the labor intensity of workers, improves construction efficiency, ensures the quality of the wall protection, and can accurately form the bolt holes for assembly. Utility Model Content

[0004] In order to achieve multiple uses of one mold, simple demolding, improved construction efficiency, and guaranteed molding quality of precast concrete assembled retaining wall, the technical solution adopted by this utility model is: a precast concrete assembled retaining wall mold, including an arc-shaped bottom template, a left overlapping cover plate, a right overlapping cover plate, a pair of side templates, a pair of cover plate molds, and several square hole core molds.

[0005] The arc-shaped bottom template is suspended and clamped between a pair of side templates for placing the steel mesh, and together with the left overlapping cover plate and the right overlapping cover plate, it forms a shaping cavity to accommodate concrete.

[0006] The two ends of the arc-shaped bottom template are respectively provided with overlapping forming cavities. The left overlapping cover plate and the right overlapping cover plate are respectively provided for one overlapping forming cavity, so that the concrete at both ends in the forming cavity forms two cooperating overlapping ear plates after solidification.

[0007] A pair of cover plate molds cover the top of the arc-shaped bottom template and are sandwiched between a pair of side templates. The outer end faces of the pair of cover plate molds are respectively joined with the inner end faces of the left overlapping cover plate and the right overlapping cover plate to enclose the upper part of the shaping cavity.

[0008] The arc-shaped bottom template and the pair of overlapping cover plates are respectively provided with a number of core mold limiting holes for installing the square hole core mold. The core mold limiting holes and the square hole core mold form a nested structure so that after the concrete in the middle of the shaping cavity solidifies, a number of wall-protecting functional square holes are formed.

[0009] Based on the above, the bottom of the arc-shaped bottom template is provided with a base for lifting the arc-shaped bottom template off the ground.

[0010] Beneficial effects: By using the base to lift the curved bottom formwork off the ground, the placement height of the curved bottom formwork is increased, avoiding the need for workers to bend over to operate. Secondly, counterweights can be placed on the base to suppress the problem of mold displacement during pouring and vibration.

[0011] Based on the above, the arc-shaped bottom template and the side template, the cover plate template and the side template, and one of the overlapping cover plates and the side template are respectively detachably connected by bolts.

[0012] Beneficial effects: The curved bottom formwork, side formwork, cover plate formwork, and overlapping cover plate can be detachably connected by bolts, which facilitates on-site disassembly and assembly. Furthermore, the splicing position and formwork size can be adjusted according to the size and shape of the precast concrete assembled retaining wall.

[0013] Based on the above, one of the overlapping forming cavities is provided with a detachable arc block, which is used to form an overlapping ear plate with an inner notch at one end of the concrete.

[0014] Based on the above, the inner side of one of the overlapping cover plates penetrates into the other overlapping forming cavity to form an overlapping ear plate with an outer notch at the other end of the concrete, and the bottom end of the overlapping cover plate is provided with an extended steel plate for connecting the arc-shaped bottom template.

[0015] Based on the above, a plurality of cylindrical holes are respectively provided on the left overlapping cover plate and the right overlapping cover plate, and sleeves are detachably installed on the cylindrical holes respectively. The sleeves are used to form bolt holes on the overlapping ear plate.

[0016] Beneficial effects: By using a sleeve, bolt holes can be directly formed on the overlapping ear plate after the concrete has been poured and solidified, eliminating the need for secondary processing, improving the accuracy of the bolt hole positions on the overlapping ear plate, and avoiding damage to the protective wall caused by drilling.

[0017] Based on the above, in order to improve versatility, the specifications of a pair of cover plate molds are the same, and the specifications of several square hole core molds are the same.

[0018] This utility model has substantial features and advancements compared to existing technologies. Specifically, the precast concrete assembly wall mold provided by this utility model suspends and detachably clamps the arc-shaped bottom template between a pair of side templates, and covers the arc-shaped bottom template with a pair of cover plate molds and detachably clamps them between the pair of side templates. This enables rapid disassembly and assembly of the arc-shaped bottom template, left overlapping cover plate, right overlapping cover plate, a pair of side templates, a pair of cover plate molds, and several square hole core molds, significantly improving the reuse rate, reducing the difficulty of wall demolding, increasing the qualified rate of finished wall products, and shortening the construction period.

[0019] Furthermore, by using the left and right overlapping cover plates to create two matching overlapping ear plates, and by using a sleeve to directly form bolt holes on the overlapping ear plates after the concrete has been poured and solidified, the secondary processing steps are eliminated, the hole position accuracy of the bolt holes on the overlapping ear plates is improved, and the phenomenon of damage to the protective wall caused by drilling is avoided.

[0020] Furthermore, by using a base to lift the curved bottom template off the ground, the placement height of the curved bottom template is increased, avoiding the need for workers to bend over to operate it. Secondly, a counterweight can be placed on the base to suppress the problem of template displacement during pouring and vibration.

[0021] Therefore, this precast concrete assembly wall mold can achieve multiple uses with one mold, simple demolding, improve construction efficiency, and ensure the forming quality of precast concrete assembly wall. Attached Figure Description

Based on their distribution, they can be designated as the left cover plate mold 24 and the right cover plate mold 12. Based on their distribution, the several square hole core molds can be divided into a middle square hole core mold 10, a right square hole core mold 11, and a left square hole core mold 23.

[0030] The arc-shaped bottom template 19 is suspended and clamped between a pair of side templates 16 for placing the steel mesh, and together with the left overlapping cover plate 24 and the right overlapping cover plate 14, forms a shaping cavity to accommodate concrete.

[0031] The arc-shaped bottom template 19 has overlapping forming cavities at both ends. The left and right overlapping cover plates each correspond to one of these cavities, so that after the concrete within the forming cavity solidifies, two mating overlapping ear plates are formed. Based on their location, these can be designated as the right overlapping forming cavity 15 and the left overlapping forming cavity, respectively. The overlapping ear plates can be divided into the right overlapping ear plate 7 and the left overlapping ear plate 4.

[0032] A pair of cover plate molds cover the arc-shaped bottom mold plate 19 and are sandwiched between a pair of side mold plates 16. The outer end faces of the pair of cover plate molds are respectively joined with the inner end faces of the left overlapping cover plate 21 and the right overlapping cover plate 14 to enclose the upper part of the shaping cavity.

[0033] The arc-shaped bottom template 19 and the pair of overlapping cover plates are respectively provided with a number of core mold limiting holes for installing the square hole core mold. The core mold limiting holes and the square hole core mold form a nested structure so that after the concrete in the middle of the shaping cavity solidifies, a number of wall-protecting functional square holes are formed.

[0034] Based on their distribution location, they can be respectively designated as the right retaining wall functional square hole 1, the middle retaining wall functional square hole 2, and the left retaining wall functional square hole 6. The core mold limiting holes can be divided into the middle core mold limiting hole 17, the left core mold limiting hole 18, the right core mold limiting hole 25, the left cover plate square hole 22, and the right cover plate square hole 13.

[0035] Specifically, the bottom of the arc-shaped bottom template 19 is provided with a base 9 for lifting the arc-shaped bottom template 19 off the ground. That is, by using the base to lift the arc-shaped bottom template off the ground, the placement height of the arc-shaped bottom template is increased, avoiding the need for workers to bend over to operate it. Secondly, a counterweight can be placed on the base to suppress the problem of mold displacement during pouring and vibration.

[0036] The arc-shaped bottom template and the side template, the cover plate template and the side template, and one of the overlapping cover plates and the side template are detachably connected by bolts.

[0037] In this embodiment, to improve versatility, the specifications of a pair of cover plate molds are the same, and the specifications of a plurality of square hole core molds are the same.

The main difference from Embodiment 1 is that, in this embodiment, several cylindrical holes 27 are respectively provided on the left and right overlapping cover plates. Sleeves are detachably installed on each of the cylindrical holes 27, and these sleeves are used to form bolt holes on the overlapping ear plates. Based on their distribution, they can be designated as left bolt hole 5 and right bolt hole 8, respectively.

[0042] Beneficial effects: By using a sleeve, bolt holes can be directly formed on the overlapping ear plate after the concrete has been poured and solidified, eliminating the need for secondary processing, improving the accuracy of the bolt hole positions on the overlapping ear plate, and avoiding damage to the protective wall caused by drilling.

[0043] Specifically, when using the precast concrete assembled retaining wall mold provided by this utility model to manufacture precast concrete assembled retaining walls, such as... Figure 1 As shown, the mold needs to be designed according to the three parameters of the wall-mounted splicing piece, and a thermal expansion allowance of 1mm should be reserved during splicing.
