Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to an adjustable-angle internal corner mold. Background Technology

[0002] For example, Chinese Utility Model Patent Publication No. CN 219548384 U discloses a weld-free internal corner template, which includes: a straight internal corner template, comprising a straight internal corner template panel, the inner side of which is detachably connected to several reinforcing ribs via a first bolt assembly, and both ends of the straight internal corner template panel being connected to a reinforcing rib via a first bolt assembly; and a corner internal corner template, comprising a corner internal corner template panel, which includes a first corner internal corner template panel and a second corner internal corner template panel, the first corner internal corner template panel and the second corner internal corner template panel being detachably connected via a right-angle connecting piece and an L-shaped connecting piece. Its angle is not adjustable, making it inconvenient for the template to loosen, and it is also inconvenient to store after disassembly. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an adjustable-angle corner mold, which is conducive to the loosening of the corner mold and is also easy to store after the template is disassembled.

[0004] To solve the above problems, an adjustable-angle concave mold was adopted, which includes:

[0005] Beam corner formwork;

[0006] The bottom corner formwork of the slab is perpendicular to the side corner formwork of the beam, and its side is flush with the inner top of the side corner formwork of the beam, thus forming a right angle with the side corner formwork of the beam.

[0007] The hinge groove is located at the inside corner formed by the side corner formwork of the beam and the bottom corner formwork of the slab.

[0008] The hinge, which is embedded in the hinge groove, includes a rotating joint and a fixed joint that share a common pin. The fixed joint is fixed to the side corner template of the beam, and the rotating joint is fixed to the bottom corner template of the plate.

[0009] With this structure, the beam side corner formwork is installed on the upper side of the beam side formwork, and the slab bottom corner formwork is installed on both sides of the slab bottom formwork, thus completing the installation of the corner formwork. During demolding, the limiting positions between the corner formwork, the beam side formwork, and the slab bottom formwork are released. As long as the corner formwork is loosened, it can be pulled away from the beam side formwork and the slab bottom formwork, realizing the corner formwork demolding. Then the slab bottom formwork can be demolded, making room for the demolding of the beam side formwork. When using slipform construction, the limiting positions of the corner formwork and the slab bottom formwork can be released first, without affecting the vertical movement of the slab bottom formwork. After the slab bottom formwork is dismantled, the corner formwork is dismantled, and then the beam side formwork is dismantled. The beam formwork and the slab bottom formwork can be stacked and then slid synchronously, which helps to save space for storing formwork and make full use of the overhead layer of the slipform system. The corner formwork can also be rotated to further reduce its height. When stacked, it is easier to pass through the bottom of the concrete.

[0010] As a further improvement of this utility model, a first rib is fixedly connected to the beam side corner template and the slab bottom corner template. The first rib is set at the end of the beam side corner template and the slab bottom corner template. A notch is opened at the intersection of the first rib, and the notch is connected to the hinge groove to allow the hinge to rotate.

[0011] With this structure, the first rib helps to reinforce the corner mold end; the notch prevents obstruction of rotation and affects storage.

[0012] As a further improvement of this utility model, a lug is provided at the end of the first rib, the lug is pin-connected to a support, a screw is installed on the support, and the two screws are connected by a straight threaded sleeve to form a diagonal brace.

[0013] With this structure, the screw and the straight threaded sleeve can easily form a diagonal brace.

[0014] As a further improvement of this utility model, the support has a U-shaped groove, which is adapted to the screw.

[0015] This structure facilitates assembly and welding.

[0016] As a further improvement of this utility model, a continuous steel back rib is provided between the first ribs at both ends, and lugs for connecting the diagonal braces are arranged at intervals along the steel back rib.

[0017] With this structure, the steel back ribs are beneficial for reinforcing the corner molds, and the lugs arranged on the steel back ribs help to form diagonal braces on the steel back ribs, thus strengthening the steel back ribs.

[0018] As a further improvement of this utility model, a second rib is provided between the steel back rib of the beam side corner template and the steel back rib of the slab bottom corner template, and a notch is also opened at the intersection of the second rib.

[0019] With this structure, the second rib helps to vertically support the steel back rib, preventing the steel back rib from bending along the template surface.

[0020] As a further improvement of this utility model, the first rib, the second rib, and the steel back rib are made of galvanized square steel pipe.

[0021] As a further improvement of this utility model, the first rib and the steel back rib are provided with assembly holes at intervals.

[0022] With this structure, bolts and nuts are fastened through the assembly holes. The first rib facilitates left and right splicing to extend the length of the corner mold, and the steel back rib facilitates splicing with the bottom mold of the plate and the side mold of the beam.

[0023] This invention facilitates the priority separation of the bottom corner formwork from the bottom formwork of the slab, and allows the beam side formwork and the bottom formwork of the slab to be stored separately and then slid synchronously after separation. Attached Figure Description

[0033] Beam corner formwork 1;

[0034] The bottom corner formwork 2 is perpendicular to the side corner formwork 1 of the beam, and its side is flush with the inner top of the side corner formwork 1 of the beam, thus forming a right angle with the side corner formwork 1 of the beam;

[0035] Hinge groove 3 is provided at the inside corner formed by the side corner formwork 1 of the beam and the bottom corner formwork 2 of the slab;

[0036] Hinges 4, which are embedded in hinge grooves 3, include rotating joints 401 and fixed joints 402 that share a common pin. Fixed joints 402 are fixed to beam side corner templates 1, and rotating joints 401 are fixed to plate bottom corner templates 2.

[0037] With this structure, the beam side corner formwork 1 is installed on the upper side of the beam side formwork, and the slab bottom corner formwork 2 is installed on both sides of the slab bottom formwork, thus completing the installation of the corner formwork. During demolding, the limiting positions between the corner formwork, the beam side formwork, and the slab bottom formwork are released. As long as the corner formwork is loosened, it can be pulled out from between the beam side formwork and the slab bottom formwork. Then, the slab bottom formwork can be removed first to make room for demolding, and then the beam side formwork can be removed. After the concrete reaches the design strength, the beam bottom formwork can be removed last. This helps to properly arrange the demolding priority. When using slipform construction, the limiting positions of the corner formwork and the slab bottom formwork can be released first without affecting the vertical movement of the slab bottom formwork. After the slab bottom formwork is dismantled, the corner formwork is moved out laterally, and then the beam side formwork is dismantled. The beam formwork and the slab bottom formwork can be stacked and then slid synchronously, which helps to save space for storing formwork and make full use of the overhead layer of the slipform system. The corner formwork can also be rotated to further reduce its height. When stacked, it is easier to pass through the bottom of the concrete.

[0038] In this embodiment, a first rib 5 is fixedly connected to the beam side corner template 1 and the slab bottom corner template 2.

A notch 6 is opened at the intersection of the first rib 5, and the notch 6 is connected to the hinge groove 3 so that the hinge 4 can rotate.

[0039] With this structure, the first rib 5 helps to strengthen the end of the corner mold; the notch 6 prevents obstruction of rotation, and with the first rib 5, it can also rotate to reduce the overall height.

[0040] In this embodiment, a lug 7 is provided at the end of the first rib 5, the lug 7 is pin-connected to the support 8, and a screw 9 is installed on the support 8. The two screws 9 are connected by a straight threaded sleeve 10 to form a diagonal brace.

[0041] With this structure, the screw 9 and the straight threaded sleeve 10 can easily form a diagonal brace.

[0042] In this embodiment, the support 8 has a U-shaped groove 801, which is adapted to the screw 9.

[0043] This structure facilitates assembly and welding.

[0044] In this embodiment, a continuous steel back rib 11 is provided between the first ribs 5 at both ends, and lugs 7 for connecting the diagonal braces are arranged at intervals along the steel back rib 11.

[0045] With this structure, the steel back rib 11 is conducive to reinforcing the corner mold, and the lugs 7 are arranged on the steel back rib 11, which helps to form diagonal braces on the steel back rib 11 and strengthen the steel back rib 11.

[0046] In this embodiment, a second rib 12 is provided between the steel back rib 11 of the beam side corner template 1 and the steel back rib 11 of the slab bottom corner template 2, and a notch 6 is also opened at the intersection of the second rib 12.

[0047] With this structure, the second rib 12 helps to vertically support the steel back rib 11, preventing the steel back rib from bending along the template surface.

[0048] In this embodiment, the first rib 5, the second rib 12, and the steel back rib 11 are made of galvanized square steel pipe.

[0049] In this embodiment, the first rib 5 and the steel back rib 11 are provided with mounting holes 13 at intervals.

[0050] With this structure, bolts and nuts are inserted through the assembly holes 13, the first rib 5 is easy to splice left and right to extend the length of the corner mold, and the steel back rib 11 is easy to splice with the bottom mold of the plate and the side mold of the beam.

[0051] This invention facilitates the priority separation of the bottom corner formwork from the bottom formwork of the slab, and allows the beam side formwork and the bottom formwork of the slab to be stored separately and then slid synchronously after separation.

[0052] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several equivalent substitutions or obvious modifications can be made without departing from the concept of the present invention, and all such modifications, with identical performance or use, should be considered within the protection scope of the present invention.
