Problems solved by technology

However, using the shear wall bolts to support the distance between the two concrete formworks on the shear wall or column, the remaining wall rod still cannot be removed, and needs to be left on the shear wall or column, and there is still room for further improvement

Embodiment 1

[0030] Such as figure 1 and figure 2 As shown, the concrete formwork distance positioning device provided in this embodiment includes two facing positioning pipes 1, which are respectively used to support the two support sleeves 2 of the positioning pipe 1, and are respectively used to fasten the two support sleeves 2 The fastening sleeve 3, and a fixed rod 4 inserted on the positioning pipe 1, the support sleeve 2 and the fixed sleeve 3, the fixed rod 4 can be a steel bar or a stud.

[0031] Such as image 3 As shown, the diameter of the positioning tube 1 gradually increases from one end to the other end, and a through hole 11 for passing through the fixing rod 4 is provided inside it, and the direction of the through hole 11 is consistent with the length direction of the positioning tube 1 . Considering that plastic material is not easily bonded to concrete, in this embodiment, the positioning pipe 1 is made of plastic material. Such as figure 2 As shown, one end of t...

Embodiment 2

[0038] The difference between this embodiment and Embodiment 1 is, as Figure 7 As shown, in this embodiment, there is only one support sleeve 2 and a fastening sleeve 3, which are used to support one of the positioning pipes 1. The specific installation and use method is the same as that of Embodiment 1, and will not be described again here, and the other has no support. The positioning pipe 1 supported by the sleeve 2 is directly in contact with the concrete formwork 5, that is, it is directly supported on the concrete formwork 5. The concrete formwork 5 is provided with a mounting hole at a position directly in contact with the positioning pipe 1, and a fixing sleeve is installed in the mounting hole. 6. The fixing sleeve 6 is provided with a through hole through which the fixing tube 4 can pass. The fixed sleeve 6 can be a conventional fixed sleeve, and its effect is mainly to increase the supporting force of the concrete formwork 5 to the fixed pipe 4. Such as Figure 7...

Abstract

The invention provides a concrete formwork spacing positioning device which can be detached from the concrete after use and can be recycled. The concrete formwork spacing positioning device comprises two positioning pipes in an opposite butt-connection mode and a fixing rod inserted in the positioning pipes in a penetrating mode. The pipe diameter of each positioning pipe gradually gets larger from one end to the other end, the ends with the smaller diameter are in butted connection, and the other ends are supported through a concrete formwork or a support part. Due to the fact that the fixing rod is inserted in the positioning pipes without making contact with the concrete and can be detached directly, the pipe diameter of each positioning pipe gradually gets larger from one end to the other end, the contact faces of the positioning pipes and the concrete have a certain inclination, the concrete formwork spacing positioning device can be detached from the shear wall or a stand column with the help of a tool, that is, all parts of the concrete formwork spacing positioning device are detachable. In addition, the detached parts can be recycled.

Description

technical field [0001] The invention relates to a concrete formwork mounting part, in particular to a concrete formwork distance positioning device. Background technique [0002] With the development of society and economy, the demand for construction continues to increase. How to improve the quality of construction and ensure the safety of construction is a hot spot that people pay attention to. In the process of building construction, when the concrete formwork is spliced ​​to form a column or a shear wall, there must be a certain distance between the two concrete formworks to ensure the thickness of the column or shear wall, because the concrete formwork may produce deflection when pouring concrete. It needs to be supported when it is moved. The common method is to use the tension bolts to support it. However, after the concrete is poured, the tension bolts cannot be removed when the concrete formwork is removed. They need to be cut off again, which affects the constructi...
