Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of wall sleeve pre-burying, and more particularly to a positionable pre-burying steel screw sleeve. BACKGROUND

[0002] Modern buildings are increasingly functional and large in size, and are mainly made of reinforced concrete. The functional diversification of buildings makes the pre-burying engineering in concrete walls and boards complex and numerous, and the construction quality of various pre-burying sleeves is increasingly required.

[0003] In the prior art, the traditional sleeve fixing method generally adopts the form of fixing the steel wire to the steel bar by binding, and the position of the sleeve is easily deviated due to the pouring of concrete during the construction stage, which causes more difficulties in the installation of the I-beam in the later stage. CONTENT OF THE UTILITY MODEL

[0004] In view of the technical problem that the pre-burying sleeve is easily deviated during the pouring of concrete in the prior art, the purpose of the embodiments of the application is to provide a positionable pre-burying steel screw sleeve, which fixes two sleeves together to form a whole and is positioned on the steel bar, so that the positions of the two sleeves are relatively fixed, and the normal installation of the I-beam in the later stage can be effectively ensured.

[0005] To achieve the above purpose, the technical solution adopted by the application is to provide a positionable pre-burying steel screw sleeve, which comprises two sleeves, a bottom welding plate and a positioning clamp, the two sleeves are arranged in parallel and one end of each sleeve is fixed on the bottom welding plate, the other end of each sleeve is provided with an internal thread, the positioning clamp is provided with a plurality of positioning clamps and is arranged on the sleeve and the bottom welding plate respectively, and the positioning clamp is connected with the steel bar in the wall.

[0006] In one embodiment, a reinforcing rib is further arranged between the two sleeves, and the two ends of the reinforcing rib are respectively welded with the two sleeves.

[0007] In one embodiment, the positioning clamp is a U-shaped plate structure, an arc-shaped plate structure or a semicircular plate structure, one positioning clamp is arranged on each sleeve, and one positioning clamp is arranged on the back of the bottom welding plate.

[0008] In one embodiment, the opening of the positioning clamp is arranged downward.

[0009] In one embodiment, the positioning clamp is welded with the sleeve and the bottom welding plate.

[0010] In one embodiment, the sleeve is welded with the bottom welding plate.

[0011] The positionable pre-buried steel screw sleeve provided by the application has the beneficial effects that two sleeves are welded through the bottom welding plate to form a whole, avoiding deviation caused by single pre-buried, so that the high-strength bolt cannot fix the I-beam in the later period; through the plurality of positioning clamps, on the one hand, the positionable pre-buried steel screw sleeve can be positioned and installed, and on the other hand, reliable connection can be formed with the wall body reinforcement, so that deviation during concrete pouring is avoided.

[0019] In order to make the technical problems to be solved by the application, the technical solutions and beneficial effects more clearly, the following will further describe the application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the application, and are not used to limit the application.

[0020] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0021] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0023] like Figures 1-4 As shown, a positionable pre-embedded steel screw sleeve provided in this application embodiment will now be described. This positionable pre-embedded steel screw sleeve includes: two sleeves 1, a bottom welding plate 2, and multiple positioning clips 3. The sleeves 1 are hollow tubes, and the sleeves 1, bottom welding plate 2, and positioning clips 3 are all steel components. The two sleeves 1 are arranged in parallel, with one end fixed to the bottom welding plate 2, specifically by welding. The other end of both sleeves 1 has internal threads for connection with high-strength bolts. Multiple positioning clips 3 are provided and respectively disposed on the sleeves 1 and the bottom welding plate 2, as shown... Figure 3 As shown, the positioning clip 3 is engaged with the reinforcing steel bar inside the wall, and is used to fix the positioning pre-embedded steel screw sleeve on the reinforcing steel bar.

[0024] To ensure a stable spacing between the two sleeves 1, a reinforcing rib 4 is provided between the two sleeves 1. The two ends of the reinforcing rib 4 are welded to the two sleeves 1 respectively. One reinforcing rib 4 can be provided, or two reinforcing ribs can be provided.

[0025] In this embodiment, the positioning clip 3 is a U-shaped plate structure, an arc-shaped plate structure, or a semi-circular plate structure. Each sleeve 1 has one positioning clip 3, and the back of the bottom welding plate 2 also has one positioning clip 3. The length of the positioning clip 3 on the sleeve 1 is less than the outer diameter of the sleeve 1, and the length of the positioning clip 3 on the bottom welding plate 2 is less than the width of the bottom welding plate 2. The opening of the positioning clip 3 faces downwards, facilitating direct attachment of the pre-embedded steel screw sleeve to the reinforcing bar. In this embodiment, the positioning clip 3 is welded to the sleeve 1 and the bottom welding plate 2.

[0026] Before pouring concrete, determine the embedded positions, heights, and other parameters according to the design drawings. After the wall reinforcement is tied on site, as follows... Figure 3As shown, the positionable embedded steel screw sleeve is fixed on the steel bar, ensuring that the positioning clamps 3 on the sleeve 1 and the bottom welding plate 2 are placed on the steel bar and reliably connected with the steel bar. Then, the concrete is poured, and after the concrete is formed, if Figure 4 As shown, the high-strength bolt is screwed into the sleeve 1, the connecting steel plate of the I-beam end surface is sleeved on the high-strength bolt, the high-strength nut is screwed, and the I-beam is installed, wherein the connecting steel plate is welded with the I-beam.

[0027] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
