Description

Technical Field

[0001] The invention relates to the technical field of construction, and in particular to an isolation and protective cover for a support frame. Background Art

[0002] Concrete pouring refers to the process of pouring concrete into a mold until it is plasticized. When the upper and lower layers need to be poured at the same time, the lower part of the vertical support frame steel pipe (support frame) needs to be supported on the bottom template (to be poured). After the concrete solidifies, the lower part of the vertical support frame steel pipe is fixed to the bottom template as a whole. At this time, if the vertical support frame steel pipe needs to be removed, the lower part of the vertical support frame steel pipe must be cut or broken, which not only causes material loss and damage, but also causes a lot of material waste. It is urgent to invent a support frame isolation protective cover to facilitate the removal of the vertical support frame steel pipe and reduce material waste. Summary of the invention

[0003] In order to overcome the shortcomings of the prior art, a support frame isolation protective cover is proposed to solve the problems raised in the above background technology.

[0004] In order to achieve the above object, the present invention is implemented through the following technical solutions: A support frame isolation protective cover comprises an isolation protective cover body, wherein the isolation protective cover body comprises a bottom surface and a side wall, a cylindrical inner cavity is provided inside the isolation protective cover body, the inner cavity extends from the upper end surface of the bottom surface to the upper end surface of the side wall, and the upper and lower diameters of the inner cavity are consistent.

[0005] As a further technical solution of the present invention: the isolation protection sleeve body is made of flexible material.

[0006] As a further technical solution of the present invention: the outer diameter of the upper part of the side wall is greater than the outer diameter of the lower part of the side wall.

[0007] As a further technical solution of the present invention: a plurality of vertical protrusions are arranged on the outer periphery of the upper and lower parts of the side wall.

[0008] Beneficial effects of the present invention: A cylindrical inner cavity is opened inside the isolation and protective cover body, which can make the isolation and protective cover body tightly cover the outside of the vertical support frame steel pipe. After use, only the vertical support frame steel pipe needs to be pulled out from the isolation and protective cover body. After the vertical support frame steel pipe is removed, the isolation and protective cover body can be easily pulled out and reused, avoiding the cutting and demolition of the contact part between the bottom of the vertical support frame steel pipe and the casting material, reducing the loss of the vertical support frame steel pipe and reducing the damage to the main structure.

[0009] The outer diameter of the upper part of the side wall is larger than the outer diameter of the lower part of the side wall. A plurality of vertical protrusions are arranged on the outer periphery of the upper part of the side wall so that the upper and lower diameters of the gap are inconsistent and there is a groove on the upper part. At this time, secondary pouring is carried out in the gap, which increases the adhesion and integrity between the new and old pouring materials, and enables the new and old main pouring materials to be better bonded.

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0013] Reference Figure 1-4 A support frame isolation protective cover comprises an isolation protective cover body 1, the isolation protective cover body 1 comprises a bottom surface 2 and a side wall 3, a cylindrical inner cavity 4 is opened inside the isolation protective cover body 1, the inner cavity 4 extends from the upper end surface of the bottom surface 2 to the upper end surface of the side wall 3, and the upper and lower diameters of the inner cavity 4 are consistent.

[0014] The isolation and protection cover body 1 is made of a flexible material with a certain strength, such as rubber or other rubber-made retractable materials. A vertical support frame steel pipe 6 is arranged in the inner cavity 4. The outer diameter of the standard vertical support frame steel pipe 6 is about 5 cm, and the pipe diameter is relatively uniform. The diameter of the inner cavity 4 is the same as the outer diameter of the vertical support frame steel pipe 6, so that the isolation and protection cover body 1 can be tightly wrapped on the outside of the vertical support frame steel pipe 6. The diameter of the inner cavity 4 can also be adjusted according to the diameter of the vertical support frame steel pipe 6. The isolation and protection cover body 1 can be generally used in construction projects.

[0015] When the upper and lower layers need to be poured at the same time, the isolation and protection cover body 1 is sleeved on the lower part of the vertical support frame steel pipe 6, and the lower part of the vertical support frame steel pipe 6 is supported on the bottom template. When the vertical support frame steel pipe 6 needs to be removed after the concrete solidifies, it is only necessary to pull the vertical support frame steel pipe 6 out of the isolation and protection cover body 1. After the vertical support frame steel pipe 6 is removed, the isolation and protection cover body 1 can be easily pulled out and reused, which reduces material loss and avoids cutting and breaking operations on the contact part between the bottom of the vertical support frame steel pipe 6 and the pouring material, reducing the loss of the vertical support frame steel pipe 6 and the damage to the main structure. The isolation and protection cover body 1 serves to isolate the vertical support frame steel pipe 6 from the cast-in-place material board surface.

[0016] Generally, the thickness of the casting plate is 80mm-150mm, and the height of the lower part of the side wall is 40-60mm, which is convenient for the secondary casting and combination with the original main structure in the later stage. The height of the upper part of the side wall can be appropriately lengthened to prepare for the construction of plates of different thicknesses, increase the repeatability of the isolation protective cover, and reduce material loss. Example

[0017] A support frame isolation protective sleeve includes an isolation protective sleeve body 1, the isolation protective sleeve body 1 includes a bottom surface 2 and a side wall 3, a cylindrical inner cavity 4 is provided inside the isolation protective sleeve body 1, the inner cavity 4 extends from the upper end surface of the bottom surface 2 to the upper end surface of the side wall 3, and the upper and lower diameters of the inner cavity 4 are consistent. The isolation protective sleeve body 1 is made of a flexible material, and this material has a certain strength, such as rubber or other rubber-made retractable materials. A vertical support frame steel pipe 6 is arranged in the inner cavity 4. Generally, the outer diameter of the standard vertical support frame steel pipe 6 is about 5 cm, and the pipe diameter is relatively uniform. The diameter of the inner cavity 4 is the same as the outer diameter of the vertical support frame steel pipe 6, so that the isolation protective sleeve body 1 can be tightly wrapped on the outside of the vertical support frame steel pipe 6. The diameter of the inner cavity 4 can also be adjusted according to the diameter of the vertical support frame steel pipe 6. The isolation protective sleeve body 1 can be generally used in construction projects.

[0018] When the upper and lower layers need to be poured at the same time, the isolation and protection cover body 1 is sleeved on the lower part of the vertical support frame steel pipe 6, and the lower part of the vertical support frame steel pipe 6 is supported on the bottom template. When the vertical support frame steel pipe 6 needs to be removed after the concrete solidifies, it is only necessary to pull the vertical support frame steel pipe 6 out of the isolation and protection cover body 1. After the vertical support frame steel pipe 6 is removed, the isolation and protection cover body 1 can be easily pulled out and reused, which reduces material loss and avoids cutting and breaking operations on the contact part between the bottom of the vertical support frame steel pipe 6 and the pouring material, reducing the loss of the vertical support frame steel pipe 6 and the damage to the main structure. The isolation and protection cover body 1 serves to isolate the vertical support frame steel pipe 6 from the cast-in-place material board surface.

[0019] Generally, the thickness of the casting plate is 80mm-150mm, and the height of the lower part of the side wall is 40-60mm, which is convenient for the secondary casting and combination with the original main structure in the later stage. The height of the upper part of the side wall can be appropriately lengthened to prepare for the construction of plates of different thicknesses, increase the repeatability of the isolation protective cover, and reduce material loss.

[0020] The outer diameter of the upper part of the side wall 3 is larger than the outer diameter of the lower part of the side wall 3, and a plurality of vertical protrusions 5 are arranged on the outer periphery of the upper part and the lower part of the side wall 3. The arrangement of the vertical protrusions 5 and the fact that the outer diameter of the upper part of the side wall 3 is larger than the outer diameter of the lower part of the side wall 3 facilitates secondary plugging at this place later. After the vertical support frame steel pipe 6 and the isolation protective sleeve body 1 are removed, a gap is left here, which needs to be secondary plugged. The arrangement of the vertical protrusions 5 and the outer diameter of the upper part of the side wall 3 being larger than the outer diameter of the lower part of the side wall 3 makes the upper and lower diameters of the gap inconsistent and the upper part has a groove. At this time, secondary casting is carried out in the gap, which increases the adhesion and integrity between the new and old casting materials, and makes the new and old main casting materials better bonded.
