Device for connecting building formwork to wall anchors

Abstract

This utility model discloses a connection device for anchoring building formwork to a wall. It includes an angle steel installed on the wall using multiple expansion bolts. A formwork is attached to one side of the angle steel and fits against the wall. Multiple through holes are provided on the surface of the formwork and on the side of the angle steel closest to the formwork. Nails are inserted into the inner cavity of the through holes where the angle steel and formwork fit together. This utility model uses expansion bolts to install the angle steel onto the wall, then attaches the formwork to the angle steel, and inserts multiple nails into the through holes where the angle steel and formwork fit together. A pull plate is then placed inside the limiting grooves on the surface of the multiple nails. The pulling assembly is then assembled and operated to move the pull plate, causing the formwork and angle steel to fit tightly together. This achieves a rapid connection using multiple nails to tighten the angle steel connected to the wall, improving connection efficiency compared to bolt connections.

Description

Technical Field

[0001] This utility model belongs to the field of building formwork technology, and in particular relates to a connection device for anchoring building formwork to walls. Background Technology

[0002] The connection between the formwork and the wall is a crucial step in ensuring the quality of concrete forming, structural stability, and construction safety during building construction. Improper connection may lead to formwork displacement, grout leakage, wall dimensional deviations or structural defects, or even safety accidents.

[0003] The method of fixing the formwork by using through bolts (tie bolts) to penetrate the formwork and the wall, along with nuts, washers, and water-stop rings (for waterproof walls), is rather cumbersome. To improve the connection efficiency between the wall and the formwork, we designed a connection device for anchoring the formwork to the wall. This device uses angle steel with multiple nail rods connected to the wall for a quick connection, which improves the connection efficiency compared to bolt connections. Utility Model Content

[0021] In the following description, embodiments of the connection device for anchoring building templates and walls according to the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-4This invention illustrates a connection device for anchoring building templates to a wall, comprising an angle steel 1 mounted on the wall by multiple expansion bolts, a template 2 attached to the wall on one side of the angle steel 1, and multiple reinforcing ribs 9 welded to the inner side of the angle steel 1. The reinforcement ribs 9 increase the overall strength of the angle steel 1 structure, effectively limiting deformation and improving stability. Multiple through holes 3 are provided on the surface of the template 2 and on the side of the angle steel 1 near the template 2. A nail rod 4 passes through the inner cavity of the through hole 3 at the point where the angle steel 1 and template 2 are attached. A limiting groove 5 is formed on the surface of the nail rod 4, and a pull plate 6 is fitted onto the surface of the multiple limiting grooves 5. The pull plate 6 is located near the angle steel 1. A plurality of sleeve grooves 7 adapted to the limiting grooves 5 are provided on one side of the steel 1. Two symmetrical pulling components 8 are provided between the angle steel 1 and the pull plate 6. The pulling component 8 includes a square shell 81 fixedly connected to the inside of the angle steel 1. A threaded sleeve block 82 is detachably placed in the inner cavity of the square shell 81. A threaded column 83 is threadedly connected to the inner cavity of the threaded sleeve block 82. One end of the threaded column 83 passes through one side of the pull plate 6 and is rotatably connected to a round plate 84. Two insertion grooves 85 are provided on the side of the pull plate 6 away from the angle steel 1 for the threaded sleeve block 82 to be inserted. A handwheel 86 is fixedly installed on the end of the threaded column 83 away from the round plate 84. Two symmetrical movable cavities 87 are provided on the front side of the square shell 81. The movable cavities 87 are adapted to the threaded column 83.

[0023] Working principle: When using this utility model, the angle steel 1 is installed on the wall using expansion bolts. Then, the template 2 is attached to the angle steel 1. Multiple nail rods 4 are inserted into the through holes 3 where the angle steel 1 and the template 2 are attached. The pull plate 6 is lifted so that the multiple sleeve grooves 7 on the pull plate 6 are respectively fitted into the inner cavities of the limiting grooves 5 on the surface of the multiple nail rods 4. Then, the threaded sleeve block 82 is inserted into the inner cavity of the square shell 81, and the threaded column 83 enters the inner cavity of the insertion groove 85, so that the circular plate 84 at the end of the threaded column 83 is located on the other side of the pull plate 6. The operating handwheel 86 drives the threaded column 83 to rotate. Because the threaded sleeve block 82 is limited by the square shell 81, the thread in the threaded sleeve block 82 causes the threaded column 83 to rotate and move. The threaded column 83 pulls the circular plate 84 to move to the left, and the circular plate 84 pulls the pull plate 6 to move to the left. The pull plate 6 then pulls the nail rods 4 to move to the left through the limiting grooves 5. The nail rods 4 then pull the template 2 and the angle steel 1 to fit tightly together.

[0024] In summary, this connection device for anchoring building formwork to the wall uses expansion bolts to install angle steel 1 onto the wall. Then, formwork 2 is attached to angle steel 1, and multiple nail rods 4 are inserted into the through holes 3 where angle steel 1 and formwork 2 are attached. A pull plate 6 is then placed inside the limiting grooves 5 on the surface of the multiple nail rods 4. Next, the pulling assembly 8 is assembled and operated to move the pull plate 6, causing formwork 2 and angle steel 1 to be tightly connected. This achieves a rapid connection using multiple nail rods to tighten the angle steel connected to the wall, improving connection efficiency compared to bolt connections.
