Problems solved by technology
[0003] In actual engineering construction, equilateral galvanized angle steel is often used as the corner guard at the junction of the exhibition hall pipe trench cover and the ground for the pipe duct of the exhibition hall. Over time, it is easy to cause the corners to collapse
[0004] To this end, an installation structure and construction method of Z-shaped corner protection for pipe trenches are provided to solve the protection construction problem of the upper side wall of pipe trenches

Embodiment Construction
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0029] see Figure 1 to Figure 3 , the present invention provides a technical solution:
[0030] An installation structure for a Z-shaped corner protection of a pipe trench, comprising a foundation 1, a pipe trench 2 is arranged on the right side of the foundation 1, and a pair of symmetrical Z-shaped steel 3 is arranged on the upper end of the right-angle connection position between the upper end opening of the foundation 1 and the pipe trench 2 The Z-shaped...

The invention relates to the technical field of installation of construction trenches, in particular to an installation structure and construction method of a pipe trench Z-shaped corner protection. The installation structure of the pipe trench Z-shaped corner protection includes a foundation; a pipe trench is arranged on the right side of the foundation; and a pair of Z-shaped steel symmetrical at the left and right direction is arranged on the upper end of the right-angle connection position between the foundation and the upper end opening of the pipe trench. The beneficial effects are as follows: by using the Z-shaped angle steel at the junction between a pipe trench cover of a exhibition hall and the ground to protect the corner, the bottom side horizontal plate of the Z-shaped angle steel can be used as the supporting surface of the pipe trench cover, and the top horizontal plate can wrap part of the ground concrete to protect the corner ground concrete; when the pipe trench coveris under pressure, the pressure can be distributed to the bottom plate and top plate of the Z-shaped steel, which avoids generating torque along the corner and causing the angle steel to crack with the ground and cause corner crack when using equilateral angle steel; and during processing, the Z-shaped steel on both sides of the pipe trench is temporarily connected and reinforced with transversesteel poles, which increases the transverse stiffness and prevents deformation of the Z-shaped steel caused by side pressure during concrete construction, wherein the temporarily reinforced transversesteel poles are removed after the concrete construction is completed.
Description
technical field [0001] The invention relates to the technical field of installation of building trenches, in particular to an installation structure of Z-shaped corner guards for pipe trenches and a construction method thereof. Background technique [0002] With the continuous development of modernization, conference and exhibition buildings have sprung up all over the country, and the exhibition hall must be designed with pipe trenches in the exhibition halls, so it is necessary to control the corner protection technology at the junction of these exhibition hall pipe trench covers and the ground Carrying out research, how to solve these boundary corner protection problems at the lowest cost, making it beautiful and ensuring the quality of the corner parts is the key to the construction of the exhibition hall pipe trench. [0003] In actual engineering construction, equilateral galvanized angle steel is often used as the corner guard at the junction of the exhibition hall pi...
