[0002] With the country's emphasis on building energy conservation, various types of prefabricated insulated wall panels have been rapidly developed and are widely used in various types of buildings such as houses and factories. Whether in prefabricated buildings or cast-in-place buildings, they are lightweight, have high thermal insulation efficiency, and good durability.

[0003] Currently, the exterior windows installed on prefabricated sandwich wall panels still require the exterior window frames to be pre-fixed to the pre-reserved exterior window grooves in the wall panels with bolts. During this process, a few centimeters need to be left between the exterior window frame and the exterior window groove, which requires the workers to constantly move the exterior window frame. This reduces the efficiency of the installation, requires constant adjustments, and increases the trouble of the actual installation operation. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figure 1-5 As shown, this utility model provides an exterior window installation structure for a prefabricated sandwich wall panel, including a wall panel 1. An exterior window groove 12 is provided on the wall panel 1, and an exterior window frame 11 is provided in the exterior window groove 12. Positioning plates 2 are provided at the upper and lower ends of one side of the exterior window frame 11. The positioning plates 2 are vertically arranged. A horizontal plate 21 is provided at the middle end of the two positioning plates 2, which is perpendicular to it. The middle ends of the two horizontal plates 21 are connected by two long rods 22. A limiting rod 24 is movably inserted into one end of the positioning plate 2 near the horizontal plate 21. The end of the limiting rod 24 passes through the positioning plate 2 and is fixedly mounted on the horizontal plate 21. One of the limiting rods 24 is provided with a scale strip 241. A lead screw 25 is threaded into the middle end of the two limiting rods 24 on the positioning plate 2. The end of the lead screw 25 is connected to the horizontal plate 21 by a bearing.

[0022] The two long rods 22 are provided with a rotating sleeve 23 with a common thread at one end facing each other. The threads of the two long rods 22 at the one end facing each other are arranged oppositely. By rotating the two long rods 22 with a common thread inside the rotating sleeve 23, and with the threads on the two long rods 22 being opposite, the two long rods 22 can be moved towards each other or away from each other according to the forward or reverse rotation of the rotating sleeve 23.

[0023] The end of the lead screw 25 away from the cross plate 21 is fixedly provided with a rotating wheel 26 with anti-slip strips on its surface. The rotating wheel 26 is provided to facilitate the operator to directly drive the lead screw 25 to rotate, thereby increasing the convenience of operation.

[0024] A support rod 27 is fixedly provided between the two ends of the long rod 22 on the opposite side of the two positioning plates 2. The purpose of the support rod 27 is to increase the accuracy of the movement of the two positioning plates 2 and avoid deviations in the adjustment between the two positioning plates 2, which would affect the actual installation effect.

[0025] The single support rod 27 is a telescopic rod structure. The purpose of setting the support rod 27 as a telescopic rod structure is to accommodate the moving long rod 22. This way, the support rod 27 can also move normally in the future, ensuring the normal use of the two positioning plates 2.

[0026] Working principle: During use, the operator pre-inserts the positioning plate 2 and the horizontal plate 21 into the side wall of the outer window frame 11. The horizontal plate 21 abuts against the horizontal surface of the side wall of the outer window frame 11, while the side of the positioning plate 2 abuts against the vertical side of the side wall of the outer window frame 11. Figure 1As shown, the operator can then directly rotate the rotating sleeve 23. At this time, the two long rods 22 with common threads inside the rotating sleeve 23 will move in opposite directions simultaneously. The moving long rods 22 will push the horizontal plate 21 fixed at the end to fully abut against the side wall of the outer window frame 11. At this time, the device will be fixedly installed between the device and the outer window frame 11. When installing the outer window frame 11 and the outer window groove 12 on the wall panel 1, if it is necessary to reserve space between the edges of the outer window frame 11 and the outer window groove 12 according to the installation requirements, the operator can simultaneously drive the two rotating wheels 26 to rotate. The rotating wheels 26 will drive the lead screw 25 to rotate. At this time, the positioning plate 2 with threads connected to the lead screw 25 will be driven away from the horizontal plate 21. According to the required reserved space, the positioning plate 2 will be controlled by the scale strip 241 reserved on the limit rod 24. The distance between the horizontal plate 21 and the positioning plate 2 is the required reserved space. Subsequently, the staff will align the outer window frame 11 with the outer window groove 12 until the side walls of the positioning plates 2 at the upper and lower ends are attached to the wall panel 1. At this time, the distance that the outer window frame 11 moves into the outer window groove 12 is the required reserved distance for installation. The staff only needs to adjust the distance between the positioning plate 2 and the horizontal plate 21 before installation. Afterwards, the outer window frame 11 can be directly installed into the outer window groove 12, and the positioning plate 2 can be attached to the wall panel 1. There is no need for multiple adjustments and movements, which improves the convenience of installation. At the same time, afterward, only the rotating sleeve 23 needs to be rotated in the opposite direction to make the two threaded long rods 22 move towards each other at the same time, so that the two horizontal plates 21 and the positioning plate 2 can be disassembled from the outer window frame 11, which is convenient for subsequent use.

[0027] All standard parts used in this invention can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connections adopt conventional connection methods in the prior art, which will not be described in detail here.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
