Problems solved by technology

Such as affecting the civilized construction of reserved holes, affecting its beauty, etc.
For example: usually the height of the reserved hole is consistent with the height of the floor, but after the floor is poured in the traditional way, the formwork is taken out, and the reserved hole is covered with wooden boards, and the height of the wooden board is higher than the floor. 10-12 mm, which not only affects the appearance and civilized construction, but also the concrete around the reserved hole is easy to crack

Embodiment 1

[0016] like Figure 1-3 As shown, the auxiliary tool for reserving holes includes a cylindrical cylinder body 1, a circular baffle plate 2 and two connecting plates 3 symmetrically arranged with respect to the cylinder body 1, and the baffle plate 2 is set on the cylinder body 1 according to the shape of the cylinder body 1. At the bottom of the cylinder body 1, one end of the connecting plate 3 is fixedly connected with the baffle plate 2 by welding, and the other end is fixed on the cylinder body 1 through the bolt 5 and the nut 7, and the connecting plate 3 is also provided with a baffle plate 2 to move up and down. track 4; in order to facilitate the operation, a handle 6 is also provided on the top of the cylinder body 1, after adjusting the height of the baffle plate 2, it is convenient to fix its height, and a gasket 8 is also provided between the connecting plate 3 and the cylinder body 1, The washer 8 is sleeved on the bolt 5. In order to be recyclable and cost-saving...

Embodiment 2

[0019] like Figure 4 As shown, the cylinder body 1 and the baffle plate 2 of the auxiliary tool with reserved holes can also be of square structure. The other structures of this embodiment, the relationship between each structure and the beneficial effects achieved are the same as those of Embodiment 1.

Abstract

The invention relates to an auxiliary tool for reserving a hole. The auxiliary tool is characterized by comprising a barrel, a baffle plate and two connecting plates which are arranged symmetrically about the barrel; the baffle plate is sleeved at the bottom of the barrel; one end of each connecting plate is fixedly connected with the baffle plate, and the other end of each connecting plate is fixed to the barrel through bolts and nuts; and each connecting plate is also provided with a track for the baffle plate to move up and down. The auxiliary tool has the advantages of contributing to civilized operation of the construction, effectively preventing the concrete at the periphery of the reserved hole from cracking, ensuring high water-proof performance of the reserved hole and recycling and saving the production cost.

Description

technical field [0001] The invention relates to an auxiliary tool for reserving holes, which belongs to the construction field. Background technique [0002] In construction, the embedding of reserved holes is extremely common. For a long time, the structure of the concrete reserved holes has always been in the traditional way, which remains unchanged, that is, a layer of wooden boards is covered above the reserved holes, so there are many problems. Such as affecting the civilized construction of reserved holes, affecting its beauty and so on. For example: usually the height of the reserved hole is consistent with the height of the floor, but after the floor is poured in the traditional way, the formwork is taken out, and the reserved hole is covered with wooden boards, and the height of the wooden board is higher than the floor. 10-12 mm, which not only affects the appearance and civilized construction, but also the concrete around the reserved holes is easy to crack.
