Abstract
Description
Technical Field
[0001] The utility model relates to an engineering construction tool, in particular to a template structure capable of automatically adjusting the curvature. Background Art
[0002] The formwork is an important tool used in concrete pouring. The traditional formwork is a flat board made of wood, which is easy to assemble and disassemble. With the development of technology, there are now some steel formworks made of steel, which need to be prefabricated according to the specific building and fixed to each other by bolts and other connectors. The advantage of steel formwork is that it is more reusable and can be easily made into the required shape, such as round, arc, etc. However, due to the high manufacturing cost and manufacturing precision requirements of prefabricated steel formworks in specific shapes, it will lose its reusability advantage, resulting in a very limited scope of application. For this reason, many buildings with curved shapes still use straight steel formworks for pouring, and the required curvature is spliced by multiple straight plates. At the same time, adjustable screws are installed on the back of the steel formwork, and the adjacent steel formworks are connected by the adjustable screws. However, this is not only difficult to operate, inefficient and poor in building precision, but also leads to obvious corners at the joints of the steel formworks. The adjustable screws can also easily cause deformation of the side of the formwork, resulting in damage to the formwork. Utility Model Content
[0003] The utility model aims to provide a self-adjusting arc template structure which can conveniently form casting templates with different arcs, so as to accurately cast the arc surface of the building, ensure the repeatability of the template and improve the construction efficiency.
[0004] The self-adjusting arc template structure described in the utility model includes a steel plate, one side of which is provided with a plurality of longitudinal ribs and transverse ribs in directions perpendicular to each other, the transverse ribs are provided with a plurality of recessed grooves, and the grooves on all the transverse ribs are relatively arranged in the longitudinal direction; one or both sides of the longitudinal ribs are equipped with connecting components for connecting and fixing adjacent steel plates to each other, connecting holes are opened on the steel plate, and there is also a pulling and fixing component that passes through the connecting holes and connects and fixes the relatively arranged steel plates.
[0005] Furthermore, the groove extends inwardly from the outer side of the transverse rib to the inner side of the steel plate.
[0006] Furthermore, the groove is V-shaped.
[0007] Furthermore, the connection assembly includes a fixing plate and a locking nut respectively installed on adjacent steel plates. A through hole is opened on the fixing plate, and the locking screw passes through the through hole of the fixing plate and is screwed and fixed to the locking nut.
[0008] Furthermore, the tension fixing assembly includes a tension bolt and a pressure block, and two ends of the tension bolt respectively pass through the connecting holes of two oppositely arranged steel plates and are screwed to the pressure block.
[0009] Furthermore, there is a sleeve, which is sleeved on the tension bolt, and two ends of the sleeve are respectively abutted against two oppositely arranged steel plates.
[0010] Furthermore, there is a pad, which is arranged on the side of the steel plate facing away from the casting position, and the steel plate is provided with a through hole opposite to the connecting hole. The tension bolts pass through the steel plate and the pad in sequence and are screwed and fixed to the pressing block.
[0011] The self-adjusting arc formwork structure described in the utility model is to sequentially arrange a number of steel plates on both sides of the concrete facade to be poured. The steel plates on the same side of the concrete facade are sequentially arranged in the transverse direction and are fixedly connected to each other through a connecting assembly. After being connected and positioned, the steel plates will be folded to a certain extent at the groove of the transverse rib due to the setting of the groove, and form a turn, so that the whole steel plate forms an arc, and then the templates connected in sequence form the required arc surface as a whole; on the other hand, the connection holes of the steel plates on both sides of the concrete facade are relatively arranged, and are fixedly connected to each other through a pulling and fixing assembly, and the space between them is the pouring position of the concrete.

[0016] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

After the connection and positioning, the steel plates will be folded to a certain extent at the groove of the transverse rib due to the setting of the groove, and form a turn, so that the whole steel plate forms an arc, and then the templates connected in sequence form the required arc surface as a whole; on the other hand, the connection holes of the steel plates on both sides of the concrete facade are relatively arranged, and are fixedly connected to each other by pulling and fixing components, and the space between them is the pouring position of the concrete.
[0021] In the self-adjusting arc template structure, the groove 4 extends inward from the outer side of the transverse rib 3 to the inner side of the steel plate 1, so that the steel plate can be easily bent at the groove; at the same time, the groove 4 is V-shaped, which makes the structural strength after deformation higher. The deformation amplitude can be effectively controlled by the opening size of the groove, thereby meeting the deformation needs while ensuring the structural strength of the template.

In addition, a sleeve 73 can be provided, the sleeve can be made of steel or plastic, the sleeve is sleeved on the tension bolt 71, and the two ends of the sleeve are respectively against the two oppositely arranged steel plates 1, which can not only protect the tension bolts and prevent the concrete from solidifying on its surface, but also exert a supporting effect on the opposite sides of the two steel plates, so as to more stably connect and position the formwork. In addition, a pad 8 can also be provided, the pad is arranged on the side of the steel plate 1 facing away from the casting position, and a through hole opposite to the connection hole 6 is opened on the steel plate, the tension bolt 71 passes through the steel plate and the pad in turn and is screwed to the pressure block, which can prevent the formwork from being deformed or even bursting due to excessive force on the tension bolt, so as to better protect the formwork.
