[0020] An adjustment component, the adjustment component is used to adjust the relative position of the connecting plate and the supporting frame;

[0021] A support member is arranged on the connecting plate, and the support frame is used for abutting against and supporting the template.

[0022] In the technical solution, the position between the support member and the base is achieved by adjusting the components, and the position of the support member can be adjusted according to needs, thereby achieving stable support for the template.

[0023] In some embodiments, the adjustment component includes:

After being supported by the support member and the template, the connection plate can be pressed against the support frame, thereby ensuring that the first rack and the second rack can be stably meshed. This method is simple and convenient to operate, and when the horizontal position needs to be fine-tuned, the first rack and the second rack will not hinder the position adjustment of the connection plate, which is convenient for fine-tuning.

[0027] In some embodiments, the length direction of the connecting plate is parallel to the mounting side and perpendicular to the first rack;

[0028] There are two first racks and they are distributed along the width direction of the support frame;

[0029] There are two second racks distributed along the length direction of the connecting plate.

Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0054] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] Please refer to all the drawings. In an illustrative embodiment of the portable formwork bracket of the present invention, the portable formwork bracket includes: a base 100, a receiving chamber 101, a piston 200, a first screw rod 300 and a support module. One side of the base 100 is the installation side. The receiving chamber 101 is opened in the base 100 and passes through the installation side along its length direction. The piston 200 is slidably connected to the receiving chamber 101 along the length direction of the receiving chamber 101. The first screw rod 300 passes through and is rotatably connected to the base 100. The length direction of the first screw rod 300 is the same as the length direction of the receiving chamber 101. The first screw rod 300 is at least partially located in the receiving chamber 101 and is threadedly connected to the piston 200. The support module is arranged on the base 100; the support module is used to abut and support the template.

[0056] Through the above scheme, the structure of the portable formwork bracket is small and convenient for manual carrying. When in use, the base 100 is placed on one side of the support below the formwork. The installation side corresponds to the support, and the first screw 300 is rotated. The first screw 300 drives the piston 200 to move, so that a negative pressure is formed between the piston 200 and the support in the accommodating chamber 101, so that the support module is fixed on the support, which is convenient for the support module to support the formwork. Its connection method is simple and fast, and the connection strength is high. There is no need to drill holes on the support or the base 100, which improves the installation efficiency and construction efficiency.

[0057] In some embodiments, the base 100 is arranged in a rectangular block, and a vertical side wall thereof is a mounting side.

[0058] Further, the depth direction of the accommodating cavity 101 is perpendicular to the installation side. In other embodiments, the installation side is one side in the thickness direction of the base 100 , and the depth direction of the accommodating cavity 101 is the same as the thickness direction of the base 100 .

[0059] In some embodiments, the cross section of the accommodating chamber 101 may be polygonal. The corresponding shape of the piston 200 is the same as that of the accommodating chamber 101, thereby ensuring that the piston 200 can seal the accommodating chamber 101 and that the accommodating chamber 101 between the piston 200 and the support ensures negative pressure without air leakage.

[0060] Furthermore, the cross section of the accommodating chamber 101 has at least one straight side, so as to prevent the accommodating chamber 101 and the piston 200 from being cylindrical, and to prevent the piston 200 from being driven to rotate synchronously when the first screw rod 300 rotates, thereby preventing the piston 200 from being able to move horizontally.

[0061] In some embodiments, a through hole is formed on a side of the base 100 away from the installation side, and the through hole is connected to the accommodating cavity 101. The first screw rod 300 is used to pass through and rotate in the through hole.

[0062] Further, when the accommodating chamber 101 is a cylinder, the axis of the through hole is colinear with the axis of the accommodating chamber 101. The first screw rod 300 coaxially penetrates and is threadedly connected to the piston 200.

[0063] In some embodiments, a bearing is detachably connected in the through hole, and the bearing may be an axial bearing, which connects the first screw 300 to the through hole, thereby ensuring that the first screw 300 does not move along its length direction. When the first screw 300 is rotated, the first screw 300 only rotates along its own axis, thereby driving the piston 200 to move along the length direction of the first screw 300.

[0064] In some embodiments, a plug plate 400 is detachably connected to a side of the base 100 away from the installation side, and a threaded hole is provided on the plug plate 400; the first screw rod 300 can be threadedly connected to the threaded hole. When necessary, the plug plate 400 can be installed, and the first screw rod 300 can be passed through and threadedly connected to the threaded hole, at which time the threaded connection between the first screw rod 300 and the base 100 is realized. The end of the first screw rod 300 can be extended out of the accommodating cavity 101 so that the end of the first screw rod 300 is connected to the prefabricated hole on the support, thereby further improving the structural strength. While the connection is achieved through the negative pressure of the accommodating cavity 101 and the piston 200, the connection is also achieved through the first screw rod 300 and the prefabricated hole, further improving the stability of the structure.

[0065] It is worth noting that before the first screw rod 300 is threadedly connected to the first threaded hole on the inserting plate 400, the axial bearing needs to be removed to release the restriction on the movement of the first screw rod 300 along its own length direction.

[0066] In some embodiments, a slot 102 is provided on the base 100, and the depth direction of the slot 102 is perpendicular to the length direction of the first screw rod 300; the plug plate 400 is used to be plugged into the slot 102 along the depth direction of the slot 102. The plug plate 400 is inserted into the slot 102 to achieve the connection between the plug plate 400 and the base 100, and then the first screw rod 300 is penetrated and threadedly connected to the threaded hole to achieve the threaded connection between the first screw rod 300 and the base 100.

[0067] In some embodiments, the support module includes a support frame 500, which is disposed on the top of the base 100, and the height direction of the support frame 500 is perpendicular to the length direction of the first screw rod 300. The entire support frame 500 is parallel to the installation side.

[0068] Further, the support frame 500 includes two support rods, and the two support rods are perpendicular to the top of the base 100. Any connecting line between the two support rods is parallel to the installation side.

[0069] Furthermore, the support frame 500 further includes a crossbeam, which connects the ends of the two support rods away from the base 100 .

[0070] In some embodiments, the support module further includes a connection plate 600 , and the connection plate 600 is disposed on a side of the support frame 500 close to the installation side.

[0071] In some embodiments, the support module further includes an adjustment component, and the adjustment component is used to adjust the relative position of the connecting plate 600 and the support frame 500 .

[0072] In some embodiments, the support module further includes a support member 110 , which is disposed on the connecting plate 600 , and the support frame is used to abut against and support the template.

[0073] The position between the support member 110 and the base 100 is achieved by adjusting the components, and the position of the support member 110 can be adjusted as needed, thereby achieving stable support for the template.

[0074] In some embodiments, the adjustment assembly includes a first rack 700 , and the first rack 700 is disposed on a side of the support frame 500 close to the installation side; the length direction of the first rack 700 is disposed along the height direction of the support frame 500 .

[0075] Furthermore, the first rack 700 is disposed on a side of the support rod close to the installation side. The length direction of the first rack 700 is the same as the length direction of the support rod.

[0076] In some embodiments, the adjustment assembly includes a second rack 800, which is disposed on a side of the support frame 500 facing the second rack 800; the second rack 800 is used to engage with the first rack 700. The connection plate 600 is adjusted along the length direction of the first rack 700, and the first rack 700 is engaged with the second rack 800 to lock the position. After being supported by the support member 110 and the template, the connection plate 600 can be pressed against the support frame 500, thereby ensuring that the first rack 700 and the second rack 800 can be stably engaged. This method is simple and convenient to operate, and when the horizontal position needs to be fine-tuned, the first rack 700 and the second rack 800 will not hinder the position adjustment of the connection plate 600, which is convenient for fine-tuning.

[0077] In some embodiments, the length direction of the connecting plate 600 is parallel to the mounting side and perpendicular to the first rack 700. There are two first racks 700 and they are distributed along the width direction of the support frame 500. That is, the two first racks 700 are connected to two support rods respectively. There are two second racks 800 and they are distributed along the length direction of the connecting plate 600. The connection of multiple first racks 700 and second racks 800 can further improve the connection stability between the connecting plate 600 and the support frame 500.

[0078] In some embodiments, a slider 900 is slidably connected to the connecting rod along its length direction. A second screw rod is threadedly connected to the slider 900. The support member 110 is rotatably connected to the end of the second screw rod. The position of the support member 110 along the length direction of the connecting plate 600 can be adjusted by the slider 900, and can be adjusted according to needs to improve the stability of the support of the template.

[0079] In some embodiments, a slide groove 601 is provided on the connecting rod, and the slider 900 is slidably connected in the slide groove 601. This solution can ensure that the second screw rod and the slider 900 slide stably on the connecting rod, thereby adjusting the position of the support member 110.

[0080] In some embodiments, the support member 110 is rotatably connected to the end of the second screw rod, so as to avoid the situation where the support member 110 is already pressed against the template and then the second screw rod is rotated to cause the support member 110 to rotate synchronously and cause the template to tilt.

[0081] In some embodiments, a stud 130 is detachably connected to a side of the support member 110 away from the second screw rod. A fixing member 120 is provided on the second screw rod, and the fixing member 120 is used to fix the support member 110 to the second screw rod. When a screw hole is prefabricated on the template, the stud 130 can be connected to the support member 110, and the second screw rod and the support member 110 are fixed by the fixing member 120. At this time, rotating the second screw rod can drive the stud 130 to rotate. The stud 130 is threadedly connected to the screw hole prefabricated in the template, which improves the connection strength between the template and the template.

[0082] Furthermore, the fixing member 120 is hinged to the peripheral wall of the second screw rod near the supporting member 110. A slot 111 is provided on the fixing member 120, and the fixing member 120 can be moved and inserted into the slot 111, so as to achieve the fixing of the second screw rod and the supporting member 110.

[0083] In some embodiments, a connection hole may be provided on one side of the support member 110 for contacting the template, and the connection hole is connected to the stud 130 to achieve fixation between the support member 110 and the stud 130 .

[0084] Furthermore, the connection hole and the stud 130 may be threadedly connected.

[0085] In another embodiment, an insert block is provided at the end of the stud 130, and the insert block can be inserted into the connection hole, so that studs 130 of different sizes can be selected according to different needs.

[0086] In some embodiments, to ensure that the stud 130 can work, the spiral direction of the stud 130 is the same as that of the second screw.

[0087] In some embodiments, a rubber pad 140 is attached to the mounting side of the base 100, and the rubber pad 140 avoids the opening of the accommodating cavity 101. The rubber pad 140 reduces the wear on the support or the base 100. In addition, the rubber pad 140 can seal the gap between the mounting side and the support to prevent air leakage in the accommodating cavity 101 from causing a decrease in negative pressure, thereby preventing the base 100 from falling off.

[0088] In some embodiments, a hand-tightening piece is provided at one end of the first screw rod 300 away from the template, and the first screw rod 300 can be manually rotated by hand through the hand-tightening piece without the need for other tools.

[0089] In some embodiments, a hand-tightening piece is provided at one end of the second screw rod away from the template, and the second screw rod can be manually rotated by hand through the hand-tightening piece without the need for other tools.

[0090] In some embodiments, the base 100, the accommodating chamber 101, the piston 200, the first screw 300, the plug plate 400 and other structures are a base module. In the portable template bracket of the present invention, there can be two base modules, which are located on both sides of the support module, that is, both ends of the support frame are bases 100, which are set according to needs.

[0091] In some embodiments, the base 100 and the support frame may be connected by stud bolts, and when the base 100 or the support module is damaged, they may be replaced separately, thus saving costs.

[0092] In some embodiments, the support frame is further provided with an inclined foot, and the two ends of the bevel are respectively connected to the support frame and the base 100, and the bevel is inclined to improve the strength between the support frame and the base 100 and reduce the inclination of the support frame.

[0093] Furthermore, the bevel is arranged on a side of the support frame away from the installation side.

[0094] In some embodiments, the connecting plate 600 and the support frame may be covered with leather covers to prevent the connecting plate 600 from being separated from the support frame and ensure that the first rack 700 is engaged with the second rack 800. When the portable template bracket is not in use, the connecting plate 600 may also be prevented from falling and being lost.

[0095] In some embodiments, a side of the rubber pad 140 facing the support may also be provided with an adhesive layer, which is sticky so that the base 100 can be attached to the support.

[0096] Through the description of multiple embodiments of the portable formwork bracket of the present invention, it can be seen that the portable formwork bracket embodiment of the present invention has at least one or more of the following advantages:

[0097] 1. When in use, place the base 100 on one side of the support below the template.
