Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction equipment technology, specifically an adjustable double shear wall expansion joint template. Background Technology
[0002] The most common method for formwork construction is to use plywood formwork, modular steel formwork, aluminum alloy formwork, composite plastic formwork, steel (aluminum) frame formwork, etc. First, complete the formwork and concrete pouring of the shear wall on one side of the expansion joint. After the outer formwork of one side of the shear wall is removed, install the formwork of the other side of the shear wall and pour the concrete of the other side of the shear wall. Finally, remove the formwork at the expansion joint.
[0003] Because the expansion joint is narrow, traditional tie bolts cannot pass through (which would occupy the space of the joint). Traditional methods require the construction of one side of the shear wall first, and then the other side, which affects the construction progress. Because the expansion joint is narrow, the external formwork of the shear wall is not easy to reinforce, which can easily lead to grout leakage and compromise the construction quality. In the later stages, the formwork at the expansion joint of the shear wall is not easy to remove, resulting in low construction efficiency.
[0004] The information disclosed in the above background section is only intended to enhance the understanding of the overall background of this utility model, and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Utility Model Content
[0005] To address the aforementioned shortcomings, the present invention aims to provide an adjustable double shear wall expansion joint formwork. The formwork width can be adjusted by means of pin holes to adapt to the expansion joint, which not only achieves easy adjustment but also ensures the quality of reinforcement construction. The formwork is easy to dismantle and the construction efficiency is high.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An adjustable double shear wall expansion joint formwork includes a first aluminum formwork panel and a second aluminum formwork panel arranged in parallel. Two or more upper pin plates are vertically arranged on the front and rear ends of the sides opposite to the first and second aluminum formwork panels. Two or more lower pin plates are vertically arranged on the front and rear ends of the sides opposite to the first aluminum formwork panel. The lower end face of the upper pin plate abuts against the upper end face of the lower pin plate. Two or more pin holes are arranged on the upper pin plate from near to far away from the first aluminum formwork panel. Two or more pin holes are arranged on the lower pin plate at the end far from the second aluminum formwork panel. The formwork also includes a front pin connecting rod and a rear pin connecting rod. Both the front and rear pin connecting rods have two or more pins vertically arranged. The pins of the front pin connecting rod are adapted to the pin holes on the front upper and lower pin plates, and the pins of the rear pin connecting rod are adapted to the pin holes on the rear upper and lower pin plates.
[0008] Furthermore, a pin upper plate and a pin lower plate, identical to those at both ends, are also provided in the middle between the front and rear ends, as well as a middle pin connecting rod connecting the pin upper plate and the pin lower plate. The structure of the middle pin connecting rod is also consistent with the structure of the pin connecting rods at both ends.
[0009] Furthermore, lifting lugs are also provided on the upper side of the first aluminum formwork panel and the second aluminum formwork panel.
[0010] Furthermore, two or more pin holes are provided on the lower plate of the pin along the direction away from the second aluminum mold panel, from near to far, with one of the pin holes located at the end of the lower plate of the pin away from the second aluminum mold panel.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] This invention achieves adjustment of the gap between the first and second aluminum formwork panels by aligning the pin holes at different distances on the upper plate with the pin holes on the lower plate and fixing them with pin connecting rods. The method of adjusting the gap is simple and reliable. The fixing with pin connecting rods makes the shear drywall formwork more stable, less prone to grout leakage, and ensures construction quality. Attached Figure Description

In the description of these embodiments, it should be understood that terms indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this embodiment and simplifying the description. They do not indicate or imply that the device or component 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.
[0016] like Figure 1As shown, the adjustable double shear wall expansion joint formwork includes a first aluminum formwork panel 1 and a second aluminum formwork panel 2 arranged relatively parallel to each other. Two or more upper pin plates 3 are vertically arranged on the front and rear sides of the first aluminum formwork panel 1 and the second aluminum formwork panel 2, respectively. Two or more lower pin plates 4 are vertically arranged on the front and rear sides of the second aluminum formwork panel 2, respectively, opposite to the first aluminum formwork panel 1. The lower end face of the upper pin plate 3 abuts against the upper end face of the lower pin plate 4. Two or more first pin holes 5 are arranged on the upper pin plate 3 from near to far along the direction away from the first aluminum formwork panel 1. The plate 3 has a second pin hole (not shown in the figure) at the end away from the second aluminum mold panel 2. It also includes a front pin connecting rod 61 and a rear pin connecting rod 62. The front pin connecting rod 61 and the rear pin connecting rod 62 are provided with two or more pins 7 in the vertical direction. The pins 7 of the front pin connecting rod 61 are adapted to the first pin hole 5 and the second pin hole (not shown in the figure) on the front pin upper plate 3 and the pin lower plate 4. The pins 7 of the rear pin connecting rod 62 are adapted to the first pin hole 5 and the second pin hole (not shown in the figure) on the rear pin upper plate 3 and the pin lower plate 4.
[0017] This invention achieves adjustment of the gap between the first aluminum formwork panel 2 and the second aluminum formwork panel 3 by aligning the pin holes at different distances on the upper plate 3 with the pin holes on the lower plate 4, and then fixing them with pin connecting rods. The method of adjusting the gap is simple and reliable. The fixing with pin connecting rods makes the shear drywall formwork more stable, less prone to grout leakage, and ensures construction quality.
[0018] As a preferred embodiment of the above implementation, a pin upper plate 3 and a pin lower plate 4, identical to those at both ends, are also provided in the middle between the front and rear ends of the opposite sides of the first aluminum formwork panel 1 and the second aluminum formwork panel 2, along with a middle pin connecting rod connecting the pin upper plate 3 and the pin lower plate 4. The structure of the middle pin connecting rod is also consistent with the structure of the pin connecting rods at both ends. This makes the shear drywall formwork more stable, less prone to grout leakage, and ensures construction quality.
[0019] As a preferred embodiment of the above-described method, lifting lugs 7 are further provided on the upper side of the first aluminum formwork panel 1 and the second aluminum formwork panel 2 to facilitate the handling and hoisting of the first aluminum formwork panel 1 and the second aluminum formwork panel 2.
[0020] As a preferred embodiment of the above-described method, two or more pin holes are provided on the lower pin plate 4 in a direction away from the second aluminum formwork panel 2, with one pin hole located at the end of the lower pin plate 4 away from the second aluminum formwork panel 2. This can further improve the adjustment range of the expansion joint.
[0021] Although the present invention has been described in detail above with specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
