Description

Technical Field

[0001] This utility model relates to the field of building construction formwork, and in particular to a pre-embedded device for shear wall tie bars. Background Technology

[0002] Masonry tie bars are important structural steel bars used in masonry structures to strengthen the connection between masonry (usually hollow bricks) and concrete components (such as frame columns, structural columns, shear walls, etc.). Their main function is to improve the overall integrity and seismic performance. During the pre-embedding process, some tie bars are embedded in the joints of the masonry, while others are suspended on the outside.

[0003] In traditional shear wall wooden formwork, after installation, the ends of the tie bars are exposed by drilling holes. On the one hand, the size of the holes is impractical; large holes are prone to grout leakage, while small holes are inconvenient to pass through. On the other hand, the drilled holes cannot be repaired to position the suspended part of the tie bars.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0021] See Figure 1 and Figure 2 This utility model provides a pre-embedded device for tie bars in shear walls, which includes: Multiple end templates 1 cover the plane where the tie bars are located. When set up, they are basically parallel to the plane where the tie bars are located (i.e., the end plane of the shear wall). There is a gap 11 between the end templates 1 for the ends of the tie bars to extend. The width of each end template 1 is greater than the width of the end plane of the shear wall to form a pouring space 10, and the length is the distance between adjacent tie bars of height. The side ends of the end templates 1 and the side templates 3 of the wall together enclose a pouring space 10.

[0022] After the formwork support is completed, cement is poured into the pouring space 10. The cement will wrap the masonry 02 to form a shear wall.

[0023] The reinforcing plate 2 is used to support the end templates 1 and increase their support strength. The reinforcing plate 2 extends along the distribution direction of the multiple end templates 1 and fits with them. The reinforcing plate 2 should cover all the end templates 1 as much as possible in terms of length, so as to achieve complementary strength among the multiple end templates 1 and achieve the purpose of joint support.

[0024] The reinforcing plate 2 has a protrusion 21 extending into the gap 11 on its contact surface with the end template 1. The protrusion 21 is adapted to the gap 11 to completely seal the gap 11. The material of the protrusion 21 is not limited and can be wood, rubber, or metal. Generally, two sets of tie bars 00 are provided at the same height position of the wall. The width of the reinforcing plate 2 is equal to the distance between the two sets of tie bars 00. The gap 11 includes an inner gap 111 between the two sets of tie bars 00 and an outer gap 112 from the tie bar 00 to the side template 3 of the wall on the same side.

[0025] If three or more sets of N tie bars 00 are installed at the same height position, the number of inner gaps 111 is N-1, while the number of outer gaps 112 is always two.

[0026] The inner gap 111 is blocked by the protrusion 21, that is, each inner gap 111 corresponds to a reinforcing plate 2; while the outer gap 112 is blocked by the sealing member 13. Two embodiments of the sealing member 13 are provided in this application.

[0027] In the first embodiment, the sealing component 13 is a sealing insert plate. Preferably, the sealing insert plate is a wooden pin structure. This structure is convenient to use and easy to process. That is, workers can cut the wooden board with a cutting saw to form a wooden pin.

[0028] In the second embodiment, the sealing element 13 can also be the same as the reinforcing plate 2, thus achieving both sealing and reinforcement.

[0029] In terms of fixation, the end template 1 and the reinforcing plate 2 are fixed together by a connector, which can be a positioning bolt, which is screwed onto the end template 1 and the reinforcing plate 2. Specifically, the end template 1 and the reinforcing plate 2 are provided with threaded holes, and the positioning bolt is installed in the threaded holes.

[0030] Of course, the end template 1 and the outer side template 3 of the wall are fixed by the horizontal keel 20. The horizontal keel 20 is a common fixing method for existing templates. During installation, the horizontal keel 20 is erected on the steel bars 21 embedded in the shear wall and has a threaded part at the end of the steel bar. During fixing, the horizontal keel 20 is fixed by screwing the bolt cap to the threaded part and pressing it.

[0031] In summary, this utility model provides a pre-embedded device for tie bars in shear walls, comprising: multiple end templates covering the plane where the tie bars are located, and generally parallel to the plane where the tie bars are located during installation; gaps are left between the end templates for the ends of the tie bars to extend out, and the width of each end template is greater than the width of the end plane of the shear wall to form a pouring space; the side ends of the end templates and the side templates of the wall together enclose a pouring space. After the templates are supported, cement is poured into the pouring space, and the cement will encapsulate the masonry to form a shear wall. A reinforcing plate is used to support the end templates and increase their support strength; the reinforcing plate extends along the distribution direction of the multiple end templates and is attached to them. The reinforcing plate has protrusions extending into the gap on its mating surface where it contacts the end template. These protrusions are adapted to the gap to completely seal it. Typically, two sets of tie bars are installed at the same height position on the wall. The width of the reinforcing plate is equal to the distance between the two sets of tie bars. The gap includes the inner gap between the two sets of tie bars and the outer gap from the tie bars to the side template of the wall on the same side.

[0032] This invention adjusts the structure of the traditional end template, changing it from an integral type to a spliced ​​type; the advantages are: 1. No drilling is required; tie bars pass through the gaps, facilitating space adjustment. 2. The positions of each end template can be adjusted independently, and the support of the tie bars can be adjusted adaptively.

[0033] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
