Problems solved by technology

Because the masonry structure is made of staggered bricks and mortar masonry, the expansion bolts cannot play their fixing role, especially when the expansion bolts are fixed to the bricks in the hollow structure and the expansion bolts penetrate the gaps between the bricks. When the slurry is used, the expansion bolts are weak in force and cannot play a fixed role
In actual engineering, cross-bolts are often used to penetrate the masonry structure for fixation. The disadvantage is that when the cross-piercing bolts penetrate into bricks, the masonry structure is damaged, and the wall where the hole is penetrated needs to be fixed. If the surface is repaired, it is easy to cause cracks and uneven quality defects on the subsequent painted surface of the wall
When the through-bolt penetrates the brick eccentrically, or when it penetrates the slurry, the slurry is likely to cause the penetration hole to be too large and loosen, so that the force on the through-bolt is unstable, and it is difficult to achieve a stable fixing effect.
In addition, when the bolts are drilled on the masonry structure, it is easy to cause the wall to crack and affect the stability of the masonry structure.

Embodiment 1

[0048] Please refer to Figure 1 to Figure 6 , Embodiment 1 of the present invention provides a chute-type prefabricated fixing member 100 , including a ligand 110 , a C-shaped steel 120 and a clip 130 .

[0049] Please refer to image 3 , wherein the opening of the C-shaped steel 120 is set outward; wherein the C-shaped steel 120 includes at least a back plate and two side plates, wherein the free ends of the side plates are downwardly provided with a blocking plate forming a C-shaped opening. Wherein the blocking plate can be bent inwards to increase its strength. Wherein the opening size of the C-shaped steel 120 is smaller than the size of the back plate. It should be noted that the C-shaped steel is different from the channel steel, and the channel steel has no blocking plate.

[0050] Please refer to figure 1 , image 3 and Figure 6 , the ligand 110 can be a concrete prefabricated slab, shaped steel or a metal block. The metal block is, for example, a steel block...

Embodiment 2

[0055] Please refer to figure 2 and Figure 7 , Embodiment 2 of the present invention provides a manufacturing method of the chute-type prefabricated fixing member 100 in which the ligand of the above-mentioned Embodiment 1 is a prefabricated concrete slab, including:

[0056] Step S1, setting the opening of the C-shaped steel 120 outward.

[0057] Step S2, vertically connect several first steel bars 111 on the back plate of the C-shaped steel 120 . Wherein the first steel bars 111 are arranged at equal intervals.

[0058] Step S3 , connecting the second steel bar 112 perpendicular to the first steel bar 111 . Wherein the second steel bar 112 includes but not limited to two.

[0059] In step S4 , a template 400 surrounded by three sides is set along the two ends of the C-shaped steel 120 and the free end of the first steel bar 111 . The formwork 400 can be a wood formwork or a metal formwork.

[0060] Step S5 , pouring concrete 114 on the first steel bar 111 and the sec...

Embodiment 3

[0065] Please refer to Figure 8 to Figure 9 Embodiment 3 of the present invention provides a method for using the chute-type prefabricated fixing member 100 in the first embodiment above, and the chute-type prefabricated fixing member 100 is built on the wall 200 of a masonry structure. Wherein the width of the chute-type prefabricated fixing member 100 can be consistent with the width of the bricks of the wall 200 of the masonry structure, so as to facilitate construction, the chute-type prefabricated fixing member 100 can be directly used as a brick masonry construction without subsequent repair construction. Make the opening surface of the C-shaped steel 120 flush with the wall surface. Wherein brick can be solid, also can be hollow. When the wall 200 needs to be painted later, the opening of the C-shaped steel 120 needs to be sealed with masking paper or adhesive tape before the painting, so as to avoid the blockage of the chute caused by the painting. When the wall 20...

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a chute-type prefabricated fixing component, a method for making and using the same, and a method for installing equipment. Background technique [0002] At present, in the mechanical and electrical equipment installation project of the building structure, when the wall of the building structure is a masonry structure, the installation of equipment such as distribution boxes is generally fixed by expansion bolts on the masonry structure. Because the masonry structure is made of staggered distribution of bricks and masonry through slurry, the expansion bolts cannot play their fixing role, especially when the expansion bolts are fixed to the bricks in the hollow structure and the expansion bolts penetrate the gaps between the bricks. When the slurry is used, the expansion bolts are weak in force and cannot play a fixed role. In actual engineering, cross-bolts are ...
