Problems solved by technology

[0003] However, the existing technology has the following defects: a. It is easy to cause water leakage in the concrete structure; b. Since the length of the embedded casing is the same as the width of the concrete structure, when it is embedded in the frame structure, it will be affected by the binding installation of steel bars. , the construction operation when it is put into the wall (beam) side formwork and fixed is extremely inconvenient; c. Since the nut must be removed from the side formwork on both sides of the beam (wall) and the screw rod can be installed after passing through the inner casing of the beam (wall), the actual operation In the beam (wall) inner side formwork (beam or wall side formwork on the side away from the building facade) is often used as a fulcrum for the adjacent slab bottom formwork (upper pressure type) or is tightly pressed by the adjacent slab bottom formwork (flat No matter which method is adopted, it will be removed at the same time as the bottom formwork of the adjacent slab, and the time will be later than the removal time of the outer side formwork of the beam (wall), which will cause the nuts to not be installed in time, thus affecting the installation time of the screw and directly affecting the construction. duration

Embodiment 1

[0032] This embodiment provides a pre-embedded device for installing external connectors 103, such as Figures 1 to 4 As shown, it includes a casing 1 and a connecting screw. The connecting screw is used to position the casing 1 and the external connector 103. The connecting screw is inserted into the casing 1 by one end of the casing 1, and the connecting screw and the casing 1 Detachable connection, such as screw connection or snap connection etc. It should be noted that the casing 1 can be realized by but not limited to steel pipe, PVC pipe and other materials, and the positioning screw 2 and structural screw 3 can be realized by steel and other materials in the prior art.

[0033] In the implementation process of this embodiment, it is convenient to install and shorten the construction period; specifically, as image 3 As shown, the implementation of this embodiment is as follows: first, as Figure 5 As shown, one end of the casing 1 is pasted on the side form 102 on the...

Embodiment 2

[0035] This embodiment provides a pre-embedded device for installing external connectors 103, such as Figures 1 to 4 As shown, it includes a casing 1 and a connecting screw. The connecting screw is used to position the casing 1 and the external connector 103. The connecting screw is inserted into the casing 1 by one end of the casing 1, and the connecting screw and the casing 1 Detachable connection, such as screw connection or snap connection etc. It should be noted that the casing 1 can be realized by but not limited to steel pipe, PVC pipe and other materials, and the positioning screw 2 and structural screw 3 can be realized by steel and other materials in the prior art.

[0036] Further, the connecting screw includes a positioning screw 2 for positioning the sleeve 1 and a structural screw 3 for positioning the external connector 103, and the sleeve 1 is provided with a positioning thread that cooperates with the positioning screw 2, so The casing 1 is also provided with ...

Embodiment 3

[0041] This embodiment provides a pre-embedded device for installing external connectors 103, such as Figures 1 to 4 As shown, it includes a casing 1 and a connecting screw. The connecting screw is used to position the casing 1 and the external connector 103.

Abstract

The invention relates to the technical field of construction engineering construction devices, and aims to provide an embedded device. The invention discloses an embedded device used for installing anexternal connecting piece. The embedded device includes a sleeve and a connecting screw, the connecting screw is used for positioning the sleeve and the external connecting piece, the connecting screw penetrates through the sleeve by one end of the sleeve, and the connecting screw is detachably connected with the sleeve. The embedded device can prevent water leakage of a concrete structure, facilitate installation and shorten the construction period; and the embedded device can further improve the overall strength of the embedded device, and the contact area between the embedded device and aside formwork is increased.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a pre-embedded device. Background technique [0002] In the process of building, municipal and bridge construction, it is usually necessary to install pre-embedded devices when pouring concrete structures to meet the needs of lap joints between different masonry structures. The pre-embedded devices in the prior art usually include screw rods, nuts and sleeves. During the installation process, the sleeves are first fixed in the side forms of the concrete wall (beams), and then concrete is poured into the side forms, and the concrete is solidified. After the wall (beam) is formed, remove the side form and put the screw in the casing, and finally install the nut on the screw, so that the screw and the nut are tightened to be stressed, thus completing the installation of the embedded device. [0003] However, the existing technology has the following defects: a. It is...
