Description

Technical Field

[0001] This utility model relates to the field of shear wall construction formwork technology, and in particular to a construction formwork device for irregular corner shear walls. Background Technology

[0002] Traditional shear wall construction formwork includes side formwork, square timber, steel pipes, tie bolts, etc. However, this type of formwork is only highly suitable for shear wall construction with right-angle corners. For shear walls with irregular corners (such as trapezoidal corners), the narrow space at the corner and the large size of the reinforcement system of traditional formwork make installation and removal difficult, cumbersome and time-consuming, resulting in low construction efficiency. Furthermore, it can easily cause the side formwork joints to be unable to be properly reinforced, leading to bulging and grout leakage, thus reducing construction quality. Utility Model Content

[0003] The purpose of this invention is to provide a construction template device for irregular corner shear walls, thereby addressing the shortcomings in the aforementioned background technology.

[0004] The technical solution of this utility model is: a construction formwork device for irregular corner shear walls, which includes several formwork components, tie bolts, anti-overflow joint components, and corner connectors. The tie bolts are used to connect two sets of formwork components arranged opposite to each other. The anti-overflow joint components are arranged on the opposite sides of the two sets of formwork components to seal the joints of adjacent formwork components on the same side. The corner connectors are arranged on the opposite sides of the two sets of formwork components to connect the steel pipe back ribs in adjacent formwork components on the same side.

[0005] Preferably, the corner connector includes a first hemisphere, a second hemisphere, a first connecting pipe, and a second connecting pipe. The first connecting pipe and the second connecting pipe are respectively connected to the curved surface of the first hemisphere and the curved surface of the second hemisphere. The flat surfaces of the first hemisphere and the second hemisphere abut against each other and are rotatably connected to change the included angle between the first connecting pipe and the second connecting pipe.

[0006] Preferably, the inner diameter of the first connecting pipe and the inner diameter of the second connecting pipe are respectively larger than the outer diameter of the steel pipe back rib, and the end of the steel pipe back rib passes through the first connecting pipe or the second connecting pipe and is connected by a pipe connector.

[0007] Preferably, the first hemisphere and the second hemisphere are respectively provided with ball connection holes, the axis of the ball connection holes being perpendicular to the plane of the first hemisphere, for installing ball connectors that connect the first hemisphere and the second hemisphere.

[0008] Preferably, the template assembly includes a side template, timber, pre-connectors, and the steel pipe back ribs. The timber and the steel pipe back ribs are arranged in a cross pattern on the same side of the side template, and the pre-connectors connect and secure the side template, the timber, and the steel pipe back ribs.

[0009] Preferably, the pre-connector includes a first limiting plate, a second limiting plate, and a plate connector for connecting the two. The first limiting plate and the second limiting plate are located on both sides of the side template, and their facing surfaces abut against the side template and the steel pipe back rib, respectively. The side template has a groove adapted to the first limiting plate.

[0010] Preferably, the seam anti-overflow component is a polyethylene film or waterproof tape attached to the template assembly.

[0011] Preferably, the tie bolt includes at least one of sleeve tie bolt and three-section tie bolt.

[0012] The beneficial effects of this utility model are: (1) By using the anti-overflow joint component to seal the joint gap of adjacent template components on the same side, the risk of grout leakage is reduced; by using the corner connector to reinforce the joint of adjacent template components on the same side, the problem of the two sets of tie bolts conflicting and difficult to quickly install and dismantle is avoided in the traditional construction process: tie bolts are respectively installed on the adjacent template components on the same side near the joint, and the problem of insufficient clamping force near the joint, resulting in bulging and grout overflow is avoided in the traditional construction process: due to the conflict between the two sets of tie bolts, at least one set of tie bolts must be installed at a position slightly further away from the joint, which leads to insufficient clamping force near the joint; the construction template device provided by the above technical solution can efficiently install and dismantle the template device and ensure the fastening effect of the irregular corner template joint, thereby improving construction efficiency and construction quality.

[0013] (2) By using pre-connectors, the side formwork, timber and steel pipe back bracing can be pre-connected and tightened before the tie bolts are installed, avoiding the problems of too many components, complicated position calibration and low construction efficiency when timber, steel pipe back bracing and tie bolts are installed and connected at the same time in the traditional construction process.

[0024] The technical solutions of the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] In the description of the embodiments of this utility model, it should be understood that the terms "top," "bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, it should be noted that unless otherwise expressly specified and limited, the terms "set" and "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in this utility model through specific circumstances.

[0026] Reference Appendix Figure 1-5This embodiment provides a construction formwork device for an irregular corner shear wall, which includes several formwork components 100, tie bolts 200, joint overflow prevention components 300, and corner connectors 400. The tie bolts 200 are used to connect two sets of formwork components 100 arranged opposite each other. The joint overflow prevention components 300 are arranged on the opposite sides of the two sets of formwork components 100 to seal the joints of adjacent formwork components 100 on the same side. The corner connectors 400 are arranged on the opposite sides of the two sets of formwork components 100 to connect the steel pipe back ribs 140 in the adjacent formwork components 100 on the same side. It is worth noting that the "adjacent formwork components 100 on the same side" mentioned here refers to adjacent formwork components 100 located on the same side of the area to be poured, which is also equivalent to adjacent formwork components 100 on the same side of the poured shear wall.

[0027] By adopting the above technical solution, the joint gaps of adjacent template components 100 on the same side are sealed by the anti-overflow joint component 300; the risk of grout leakage is reduced; and the joint of adjacent template components 100 on the same side is reinforced by the corner connector 400. This avoids the problem in traditional construction processes where tie bolts 200 are installed near the joint on adjacent template components 100 on the same side, causing the two sets of tie bolts 200 to conflict with each other and making them difficult to install and remove quickly. It also avoids the problem in traditional construction processes where the conflict between the two sets of tie bolts 200 requires at least one set of tie bolts 200 to be installed at a position slightly further away from the joint, which leads to insufficient clamping force near the joint, resulting in formwork bulging and grout overflow. The construction template device provided by the above technical solution can efficiently install and remove the template device and ensure the tightness of the joint of irregular corner templates, thereby improving construction efficiency and construction quality.

[0028] Reference Appendix Figure 4-5 The corner connector 400 in this embodiment includes a first hemisphere 410, a second hemisphere 420, a first connecting pipe 430, and a second connecting pipe 440. The first connecting pipe 430 and the second connecting pipe 440 are respectively connected to the curved surface of the first hemisphere 410 and the curved surface of the second hemisphere 420. The flat surfaces of the first hemisphere 410 and the second hemisphere 420 abut against each other and are rotatably connected to change the included angle between the first connecting pipe 430 and the second connecting pipe 440.

[0029] The first hemisphere 410 and the second hemisphere 420 are respectively provided with ball connection holes 450. The axis of the ball connection hole 450 is perpendicular to the plane of the first hemisphere 410. It is used to install the ball connector 460 connecting the first hemisphere 410 and the second hemisphere 420. By loosening the ball connector 460, the first hemisphere 410 and the second hemisphere 420 can have rotational freedom. When rotating the first hemisphere 410 or the second hemisphere 420, the included angle of the first connecting pipe 430 and the second connecting pipe 440 can be changed to adapt to the fastening requirements of the template at the joint of different irregular corners (such as trapezoidal corners). After adjusting the included angle of the first connecting pipe 430 and the second pipe to fit the irregular corner in the construction scene, the ball connector 460 can be locked.

[0030] The first connecting pipe 430 and the second connecting pipe 440 are respectively used to connect the steel pipe back ribs 140 in the adjacent template components 100 on the same side. Therefore, the inner diameter of the first connecting pipe 430 and the inner diameter of the second connecting pipe 440 are larger than the outer diameter of the steel pipe back ribs 140. The end of the steel pipe back ribs 140 passes through the first connecting pipe 430 or the second connecting pipe 440 and is connected by the pipe connector 480.

[0031] To facilitate connection, the first connecting pipe 430, the second connecting pipe 440, and the steel pipe back rib 140 are each provided with a pipe connection hole 470 for installing the pipe connector 480. The steel pipe back rib 140 is inserted into the first connecting pipe 430 (or the second connecting pipe 440) so that the pipe connection hole 470 on the steel pipe back rib 140 corresponds to the pipe connection hole 470 on the first connecting pipe 430 (or the second connecting pipe 440), and then the pipe connector 480 is inserted.

[0032] After removing the pipe connector 480, steel pipe back ribs 140 of different lengths can be inserted into the first connecting pipe 430 (or the second connecting pipe 440) to meet the needs of different construction scenarios.

[0033] Both the ball connector 460 and the pipe connector 480 mentioned above can use high-strength bolts commonly found on construction sites.

[0034] Reference Appendix Figure 2-3The template assembly 100 in this embodiment includes a side template 110, timber 120, pre-connectors 130, and steel pipe back ribs 140. The timber 120 and steel pipe back ribs 140 are arranged in a cross pattern on the same side of the side template 110. The timber 120 is vertical and located between the side template 110 and the steel pipe back ribs 140, while the steel pipe back ribs 140 are horizontally positioned. The pre-connectors 130 connect and secure the side template 110, timber 120, and steel pipe back ribs 140. By using the template assembly 100, the side template 110, timber 120, and steel pipe back ribs 140 can be pre-connected and secured before the tie bolts 200 are installed. This avoids the problems of excessive components, cumbersome position calibration, and low construction efficiency when the timber 120, steel pipe back ribs 140, and tie bolts 200 are installed and connected simultaneously in traditional construction processes.

[0035] The pre-connector 130 includes a first limiting plate 131, a second limiting plate 132, and a plate connector for connecting the two. The first limiting plate 131 and the second limiting plate 132 are located on both sides of the side formwork 110, and their facing surfaces abut against the side formwork 110 and the steel pipe back rib 140, respectively. The side formwork 110 has a groove 111 that matches the first limiting plate 131. It is worth noting that "matching" includes matching in shape, cross-sectional dimensions, thickness, etc., so that the plate surface of the first limiting plate 131 facing away from the second limiting plate 132 can be flush with the plate surface of the side formwork 110, avoiding the problem of the first limiting plate 131 partially or completely protruding from the side formwork 110, which would cause the cast shear wall sidewall to have depressions or uneven surfaces.

[0036] During construction, the timber 120 and steel pipe back rib 140 are first precisely arranged on one side of the side formwork 110. The first limiting plate 131 is installed in the groove 111 of the side formwork 110, and the plate connector passes through the side formwork 110 and is then connected to the second limiting plate 132.

[0037] To prevent depressions in the sidewalls of the cast shear wall, the plate connector in this embodiment includes a connecting rod 133 and a nut 134. One end of the connecting rod 133 is fixedly connected to the surface of the first limiting plate 131 near the second limiting plate 132, and the other end passes through the second limiting plate 132 and is threaded to the nut 134. This embodiment does not use traditional discrete bolts, which avoids the problem of uneven shear wall sidewalls caused by the ends of discrete bolts protruding from the surface of the first limiting plate 131.

[0038] The aforementioned joint overflow prevention component 300 is a polyethylene film or waterproof tape that is attached to the template assembly 100 (especially the upper surface of the side template 110 facing the area to be poured). During construction, two parts of the same polyethylene film or waterproof tape are attached to the adjacent side templates 110 on the same side to seal the joint and effectively prevent grout leakage at the joint.

[0039] The aforementioned tie bolt 200 includes at least one of sleeve-type tie bolt 200 and three-section tie bolt 200.

[0040] Compared with the prior art, the beneficial effects of this utility model include at least the following:

[0041] (1) The joint gaps of adjacent template components 100 on the same side are sealed by the anti-overflow joint component 300 to reduce the risk of grout leakage; the joint of adjacent template components 100 on the same side is reinforced by the corner connector 400 to avoid the problem in the traditional construction process: the two sets of tie bolts 200 are installed near the joint on the adjacent template components 100 on the same side, which causes the two sets of tie bolts 200 to conflict with each other and are difficult to install and remove quickly. It also avoids the problem in the traditional construction process: the two sets of tie bolts 200 must be installed at a position slightly away from the joint due to the conflict between the two sets of tie bolts 200, which leads to insufficient clamping force near the joint, resulting in bulging and grout overflow. The construction template device provided by the above technical solution can efficiently install and remove the template device and ensure the fastening effect at the joint of the irregular corner template, thereby improving construction efficiency and construction quality.

[0042] (2) By using pre-connector 130, the side formwork 110, timber 120 and steel pipe back rib 140 can be pre-connected and tightened before the installation of tie bolt 200, thus avoiding the problems of too many components, complicated position calibration and low construction efficiency when timber 120, steel pipe back rib 140 and tie bolt 200 are installed and connected at the same time in the traditional construction process.

[0043] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
