Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a casting template for double shear walls. Background Technology

[0002] Double shear walls, also known as double-limb shear walls or linked shear walls, are a common lateral force resisting system in high-rise building structures. They are composed of two or more parallel shear wall limbs, forming a cooperating overall structural unit.

[0003] Currently, the traditional method for constructing double shear walls involves filling the space between the two walls with extruded polystyrene (XPS) boards as formwork. This method has low installation precision and is prone to displacement during concrete pouring, making it difficult to control the wall dimensions. Furthermore, the XPS boards between the walls cannot be removed after demolding, affecting the appearance quality and causing material waste. This method needs to be improved. Utility Model Content

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 , Figure 2 As shown, a casting template for a double shear wall includes a pair of inner templates 1, a pair of outer templates 2, an adjusting frame 3, a screw 4, and a nut 5.

[0018] like Figure 1 , Figure 2 As shown, a pair of inner templates 1 are arranged vertically side by side, and a pair of outer templates 2 are respectively arranged vertically on the outside of each inner template 1. An adjusting frame 3 is arranged between the pair of inner templates 1 and is used to adjust the distance between the pair of inner templates 1.

[0019] like Figure 1 , Figure 2 As shown, the screw 4 is horizontally mounted on the inner template 1, and the inner template 1 has a screw hole 11 for the end of the screw 4 to be screwed in. The screw 4 passes through the outer template 2, and the nut 5 is threaded to the screw 4 and is used to press the outer template 2.

[0020] like Figure 2 , Figure 3 As shown, a strip-shaped hole 41 is provided through the screw 4 along its length, and a wedge-shaped pressure plate 42 is vertically inserted into the strip-shaped hole 41. The pressure plate 42 is used to abut against the nut 5. A wire hole 43 is provided at the upper end of the pressure plate 42 to facilitate the convenient carrying of multiple pressure plates 42.

[0021] When pouring concrete for a double shear wall, first assemble and fix the adjusting frame 3 with a pair of inner formwork 1. Then, hoist the pair of inner formwork 1 and fix them vertically to the ground. Then, use the adjusting frame 3 to adjust the spacing between the pair of inner formwork 1 to meet the construction requirements of double shear walls with different spacing.

[0022] Then screw the screw rod 4 into the screw hole 11 on the inner template 1, so that the outer template 2 is fitted onto the screw rod 4. Finally, tighten the nut 5 to press the outer template 2, thus fixing the outer template 2. Then insert the pressure plate 42 into the strip hole 41 on the screw rod 4 to limit the nut 5 and prevent it from loosening. Finally, the double shear wall can be poured.

[0023] Therefore, by setting up a combined template consisting of inner and outer parts, and adding an adjustment frame 3 between a pair of inner templates 1, the spacing between the inner and outer templates can be adjusted to meet the pouring requirements of double shear walls with different spacings and improve practicality.

[0024] Meanwhile, the outer template 2 is connected and fixed by screws 4 that can be installed from the outside, which solves the problem of difficult operation in narrow spaces, simplifies the installation and dismantling process, allows for fine adjustment of the wall size, ensures high-precision template installation, ensures construction quality, enables reusability, and reduces material waste.

[0025] like Figure 4 , Figure 5 As shown, the adjustment frame 3 includes an adjustment rod 31 and multiple sets of telescopic frames 32. The adjustment rod 31 is set vertically, and each set of telescopic frames 32 includes a pair of adjustment blocks 321, a pair of adjustment seats 322, and multiple pull rods 323.

[0026] like Figure 4 , Figure 5 As shown, a pair of adjusting blocks 321 are sleeved on adjusting rod 31, and the adjusting rod 31 is provided with a bidirectional threaded section 311 that is threadedly connected to the pair of adjusting blocks 321. Adjusting seat 322 is provided on the back side of the inner template 1, and the pull rods 323 are in pairs, with one end rotatably connected to the adjusting block 321 and the other end rotatably connected to the adjusting seat 322.

[0027] When it is necessary to adjust the spacing between a pair of inner templates 1, the control rod 31 is rotated. At this time, the bidirectional threaded section 311 on the control rod 31 controls a pair of adjustment blocks 321 to move closer or further apart, and drives the pull rod 323 to rotate, thereby adjusting the spacing between a pair of adjustment seats 322, and thus adjusting the spacing between a pair of inner templates 1.

[0028] Therefore, by setting multiple sets of telescopic frames 32 between a pair of inner templates 1 and using an adjusting rod 31 for control, the vertical and flatness of the wall can be easily controlled, ensuring high-precision template installation and ensuring construction quality.

[0029] like Figure 5 , Figure 6 As shown, the back of the adjusting seat 322 is provided with a mounting plate 324, and the back of the inner template 1 is provided with an upper opening and a mounting slide rail 325 for the mounting plate 324 to slide into. A locking pin 326 is threaded onto the mounting slide rail 325, and a locking hole 327 is provided on the mounting plate 324 for the locking pin 326 to be inserted.

[0030] When it is necessary to connect the adjusting frame 3 to the inner template 1, the mounting plate 324 is vertically slid into the mounting rail 325, and then the locking pin 326 is tightened to engage the locking hole 327, thus assembling the adjusting frame 3 and the inner template 1. Furthermore, by providing a detachable connection between the adjusting frame 3 and the inner template 1, separate transportation is possible, while also facilitating rapid on-site assembly and construction.

[0031] like Figure 7 As shown, the adjusting rod 31 includes multiple rod sections 312. Each rod section 312 has an insert rod 313 at its upper end and an insertion hole 314 at its lower end for inserting the insert rod 313. A pin 315 is horizontally provided at the lower end of the rod section 312 to pass through the insert rod 313.

[0032] Therefore, by setting segmented adjustment rods 31, the number of rods 312 can be selected according to needs, adapting to different construction requirements and improving practicality.

[0033] like Figure 7 As shown, the cross-sections of the insertion rod 313 and the insertion hole 314 are both hexagonal to facilitate the connection of an electric wrench to achieve rotational control of the adjusting rod 31.

[0034] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
