A small-scale demolition crowbar for industrial building engineering construction

Abstract

The invention provides a small-scale demolition crowbar for industrial construction engineering construction, which includes a crowbar main body, a fixed collar, a fixed pick hammer, a nail head and an elongated stick body; the stick body on the crowbar main body, etc. There are three fixed collars, and the fixed collar and the main body of the crowbar are cast integrally; The tapered heads are respectively arranged at the two ends of the main body of the crowbar; the fixing collar is inserted into and installed with a fixed hammer; The small-scale demolition crowbar used in industrial building construction is provided with six reinforced anti-skid ribs arranged around the outer wall of the crowbar main body and the extended stick body, and the reinforced anti-skid ribs run through the entire crowbar main body and the extended stick body. The body structure is beneficial to enhance the use strength of the main body of the crowbar and the extended stick body, and prevent the phenomenon of breaking during the prying process.

Description

technical field [0001] The invention relates to the technical field of industrial building engineering tools, in particular to a small-scale demolition crowbar used in industrial building engineering construction. Background technique [0002] A crowbar is a labor tool widely used in construction, railway track repair and maintenance. Since it also appeared in the game "Half-Life" series and was used freely by the protagonist Gordon Freeman, it is also called the "Holy Sword of Physics" by netizens, or the origin stick. The crowbar is a method of using the principle of leverage to let the heavy object overcome the gravity of the earth, lift the heavy object from the ground and shift it. Crowbars are divided into hexagonal sticks, round sticks and flat crowbars. Hexagonal sticks and round sticks can be processed into: two round ends, two flat ends or one round end and one flat end, which can be used as construction tools or hardware tools, and the latter can be used as car t...

Problems solved by technology

[0007] The purpose of the present invention is to provide a small-scale dismantling crowbar for industrial building engineering construction, to solve the problem that the existing crowbar structure design proposed in the above-mentioned background technology is relatively traditional and simple, and the method of using prying is single; although some crowbars It can be extended and used. For example, the second patent mentioned above can use the crowbar to be extended. The lengthening method is fixed by thread. As we all know, the crowbar needs to be pried by the principle of leverage. Long-term prying will affect the use of the thread. The life of the crowbar will cause damage to the thread, and further cause the crowbar to be lengthened and difficult to install, so that the crowbar cannot be lengthened for use; moreover, most of the existing crowbars have a structure with two ends, and are generally equipped with two prying heads. As a result, the scope of adaptation is small, and it cannot be adapted to the use of various operating environments; and the existing crowbars cannot be used in combination, and combined prying cannot be performed according to the use requirements, thereby increasing the prying method, so as to better dismantle the demolished objects operations, further reducing the output of labor and improving labor efficiency
