Description

Technical Field

[0001] The invention relates to the technical field of construction protection, and in particular to a tool for hole protection. Background Art

[0002] At present, it is common to protect the opening after removing the formwork. However, due to the serious lag in opening protection, it is easy to cause safety accidents on site, and there are safety hazards such as falling from heights and being hit by objects.

[0003] When the traditional hole protection is used for the formwork of the wall column of the formwork layer, the finished product cannot fully cover the hole because of the presence of the formwork and the back ribs. Especially when the secondary structure around the hole is poured together on site, there are clamps, which makes it even more impossible to cover the hole. In addition, there is a large lag in the on-site hole protection. The finished hole can only be made after the formwork is removed. Summary of the invention

[0004] To solve the above problems, the present invention discloses a hole protection tool, including a support member, wherein the support member is a rectangular parallelepiped frame composed of a plurality of rods. The support member is a supporting load-bearing structure of the tool, and the size of the support member can be adaptively changed according to needs, that is, according to the actual depth and size of the hole.

[0005] The upper end of the support member is fixedly connected with a cover plate, which is used to block the hole, thereby improving the protection capability.

[0006] The upper end of the cover plate is fixedly connected with two hanging plates, and the lower part of the hanging plate passes through the cover plate and is fixedly connected to the support member, and a hanging hole is opened in the middle of the hanging plate. The hanging plate is used for transportation and lifting, that is, lifting tools into the hole or taking tools out of the hole.

[0007] Preferably, the rod member includes a vertical rod and a horizontal rod, four vertical rods are provided, and a square frame composed of horizontal rods is fixedly connected between the four vertical rods. The square frame composed of horizontal rods is provided with multiple layers, thereby improving the supporting strength of the supporting member.

[0008] Preferably, the rod is an angle steel, which is a common building material at the construction site, and the tool can be made and used at the construction site.

[0009] Preferably, the rod is a steel pipe, which is a common building material at the construction site, and the tool can be made and used at the construction site.

[0010] The beneficial effects of the present invention are as follows:

[0011] 1. The present invention combines the support, cover plate and hanging point into a whole, changing the protection after demoulding to protection before supporting the formwork, and the support can be used cyclically, meeting the low-carbon and environmental protection requirements called for by the country.

[0012] 2. The present invention has a simple structure and can be quickly manufactured using materials from the construction site according to the size of the hole, thereby improving the construction effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0019] Combination Figure 1 to Figure 2 As shown, a tool for protecting a hole includes a support member 1, which is a rectangular parallelepiped frame composed of a plurality of rods. According to the size of the hole, the specification of the support member 1 is 1600×600×2800mm.

[0020] The upper end of the support member 1 is fixedly connected with a cover plate 2. The cover plate 2 is made of a wooden building formwork or an aluminum building formwork. If a wooden building formwork is used, its size is 1600×600×10mm, which just covers the upper end of the support member 1. At the same time, holes are drilled in the wooden building formwork, and steel bars are tied through the holes and fixed to the support member 1. If an aluminum building formwork is used, the upper end of the structural support member 1 needs to be spliced ​​together, and bolts, nuts and other parts are used to fix it. Relatively speaking, it is preferred to use wooden building boards, which are easier to cut into specified sizes according to the upper end surface of the support member 1, facilitate rapid production on site, and reduce the overall quality of the tool.

[0021] Two hangers 3 are fixedly connected to the upper end of the cover plate 2. The size of the hangers 3 is 100×100×10mm, and the material used is galvanized steel plate. The lower part of the hanger 3 passes through the cover plate 2 and is fixedly connected to the support 1. A hanging hole is opened in the middle of the hanger 3, and the diameter of the hanging hole is 40mm, that is, two through holes are reserved on the cover plate 2. The cover plate 2 is directly covered on the support 1, and under the action of the hangers 3, the cover plate 2 can be limited on the horizontal plane, and the above-mentioned method of using steel bar tying wire to fix can be omitted.

[0022] The tool is used by reaching into the hole from below, and the cover plate 2 blocks the hole opening to achieve protection. After using the tool, the construction above the cover plate 2 is not affected, and it also avoids debris such as fallen rocks falling into the hole during the construction above, causing harm to possible construction workers.

[0023] The rod member includes a vertical rod 11 and a horizontal rod 12. Four vertical rods 11 are provided, and a square frame composed of horizontal rods 12 is fixedly connected between the four vertical rods 11. Figure 2 As shown, there are three layers of square frames, and the distance from the ground of each layer of square frames is 990mm, 1890mm, and 2800mm, and two cross bars 12 are fixedly connected to the top layer of the square frames, and the lower parts of the two hanging plates 3 are fixedly connected to the two cross bars 12, respectively, to facilitate the lifting of tools.

[0024] The rod is an angle steel or a steel pipe. When angle steel is used, the specification used is isosceles angle steel of 30×30×3mm. If steel pipe is used, galvanized steel pipe with a size of DN125 is used.

[0025] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above technical features.
