Description

Technical Field

[0001] The present invention relates to the technical field of building tools, and in particular to a pre-embedded anchor piece of an ALC plate and an ALC plate installation method based on the anchor piece. Background Art

[0002] ALC (autoclaved aerated lightweight concrete) panels have a wide range of applications due to their lightweight and environmentally friendly characteristics, and are very suitable for the green building concept pursued by today's society. However, ALC products are porous and lightweight, which makes them relatively brittle compared to other building materials. Therefore, the installation method is very important when connecting them to other building structures, and it is necessary not to damage the ALC panels and ensure strength.

[0003] There are two main methods for installing ALC panels. If the pressure-bearing capacity of ALC panels is not high, the metal parts are directly installed and anchored into the ALC panels to connect with the structure. If the pressure-bearing capacity is relatively high, a metal plate will be embedded in the ALC panels, and then the metal parts will be installed and anchored into the metal plates to provide a slightly larger anchoring force. Both of the above methods have certain defects. The first installation method has a low pressure-bearing capacity. In the second installation method, the thinner metal plates cannot provide a strong anchoring force; the thicker metal plates will make it difficult for the metal bolts to penetrate during installation, causing installation difficulties.

A guide tube 3 is vertically installed on the upper part of the anchor box 1, and the guide tube 3 is opposite to the through hole formed by the semicircular grooves 42 on the two groups of anchor plates 4; the upper part of the connecting head 2 is provided with an external thread 23, and the lower part of the connecting head is provided with a conical head 21, the diameter of the conical head 21 is larger than the diameter of the semicircular groove 42, and the conical head 21 is located below the anchor plate 4, the connecting head 2 passes through the top of the anchor box 1, and the guide tube 3 is sleeved on the outside of the connecting head 2, and the external thread 23 is exposed.

[0036] See also Figures 3-4 The elastic reset device includes a guide rod 5 and a spring 6. The guide rod 5 is fixedly mounted on the side wall of the anchor box 1. The length direction of the guide rod 5 is perpendicular to the side wall of the anchor box 1. The spring 6 is sleeved on the guide rod 5 and contacts the side wall of the anchor box 1. The anchor plate 4 is provided with a collar 43. The collar 43 is sleeved on the guide rod 5 and contacts the spring 6. In order to increase the sliding stability of the anchor plate 4, a guide rail 11 arranged in the left and right directions is provided in the anchor box 1. The anchor plate 4 is provided with a guide slider 41, and the guide slider 41 is located in the guide rail 11. The anchor plate 4 is installed at the bottom of the anchor box 1. The bottom wall of the anchor box 1 is provided with a recess 12 for accommodating a conical head 21. The diameter of the conical head gradually increases from bottom to top, and the diameter of the top of the conical head is larger than the diameter of the semicircular groove; a necking neck 22 is provided above the conical head 21, and the diameter of the necking neck 22 is slightly smaller than the diameter of the semicircular groove 42. The elastic reset device is provided in 6 groups, and 3 groups of elastic reset devices are provided on the left and right sides of the anchor box 1 and arranged symmetrically.

In addition, the anchor plate is directly welded on the steel mesh, and the force it is subjected to is transmitted to the entire plate, which will not cause local plate rupture, and has high safety.

[0038] See also Figures 5 to 7 10. This embodiment also relates to an ALC plate installation method with pre-embedded anchors, which comprises the following steps:

[0039] S1. ALC sheet production: An anchor box 1 is fixed on the steel mesh cage of the ALC sheet 101. The steel mesh cage includes an upper steel mesh sheet 9 and a lower steel mesh sheet 10. The anchor box 1 is welded to the lower steel mesh sheet 10 by ear keys, and a sealing head 8 is provided on the guide tube on the anchor box. The sealing head 8 is integrally formed with the guide tube 3. Before casting the ALC sheet, multiple layers of steel mesh cages (such as Figure 5 and 6 As shown), two adjacent anchor boxes on different steel mesh sheets are in contact with each other; the sealing head 8 is provided to prevent the concrete from clogging the guide tube; the steel mesh cage is placed in a casting mold, concrete is poured in and cured, and after curing, the ALC block is cut, the cutting plane is parallel to the steel mesh sheet, and the sealing head 8 on the guide tube is cut off at the same time, and the production of the ALC plate 101 is completed;

[0040] S2. Insert the connector from the guide tube. When the conical head 21 at the bottom end of the connector 2 contacts the anchor plate 4, an outward force is applied to the anchor plates 4 on both sides, so that the collar 43 on the anchor plate 4 squeezes the spring 6, and the anchor plate 4 moves to the left and right sides, forming a gap between the two groups of anchor plates 4. When the conical head 21 at the bottom end of the connector 2 is completely located below the anchor plate 4, since the diameter of the neck portion 22 of the conical head 21 is smaller than the diameter of the top of the conical head 21, the two groups of anchor plates 4 are reset under the action of the spring 6 and the conical head 21 is stuck. An external thread is provided at one end of the connector, and a lifting ring 10 is installed through the external thread. The lifting rope 107 is connected to the lifting ring 10 to lift the ALC plate 101 to the installation position, and the lifting ring 10 is removed (such as Fig.10 shown);

[0041] S3, ALC plate installation: remove the lifting ring 10 from the external thread at the top of the connector, install the connector on the connector of the ALC plate 101, and screw the nut on the connector to fix the connector. The ALC plate is fixed to other concrete beams through the connector. In this embodiment, the connector is an elastic hardware 109, one end of the elastic hardware 109 is fixedly installed on the ALC plate 101 through the nut 102 and the connector, and the other end of the elastic hardware 109 is fixedly installed on the concrete beam 103 through the nail 110. The middle part of the elastic hardware 109 is bent and inserted between the superstructure structure (concrete beam 103) and the ALC plate 101. Finally, the adhesive 112 is filled between the top of the ALC plate and the superstructure structure (concrete beam 103); the bottom of the ALC plate 101 is also connected to the lower structure through the pipe clamp 111 and the adhesive 112, such as Figure 7 As shown, the ALC panels installed in this embodiment are used as interior walls.

[0042] The anchors in this installation method are directly welded to the steel mesh, and the force they are subjected to is transmitted to the entire plate through the steel mesh cage, which will not cause local rupture of the plate and has high safety.

[0043] Embodiment 2

[0044] See also Figures 8-9 The difference between this embodiment and the first embodiment is that: in step S2, the connecting part is replaced by a sliding S plate 104, and metal embedded parts 106 are embedded in the superstructure structure and the substructure structure (both are concrete beams 103), and the exposed part of the metal embedded parts 106 is welded with angle steel 105, and the sliding S plate 104 is installed on the connecting head of the ALC plate 101, and a nut is screwed on the connecting head to fix the sliding S plate 104. During installation, the sliding S plate 104 is used to clamp the angle steel 105 to complete the hanging of the ALC plate 101. The ALC plate 101 in this embodiment is used for the exterior wall during hanging.
