Description

Technical Field

[0001] This utility model relates to the field of pre-embedded parts technology, specifically a railing slot pre-embedded part. Background Technology

[0002] In ancient China, railings were called langan or goulan. They are safety facilities on bridges and buildings. In use, railings serve to separate and guide, making the boundaries of the divided areas clear and distinct. Well-designed railings are also very decorative.

[0003] Typical standard guardrails usually consist of railings, posts, and foundations. The conventional method of fixing railings is to install expansion bolts on the structure to fix the railings. This method is prone to damaging the structure, and can cause great damage to small parapet walls, eaves, and other structural parts. Therefore, in order to respond to the requirements of cost reduction and efficiency improvement and civilized construction on the construction site, standard guardrails and fences that are sturdy, easy to disassemble, have a high turnover rate, and cause little structural damage are essential.

[0004] In response to this type of railing enclosure, a new type of railing slot-type embedded part has emerged. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the structure is easily damaged, and that small-sized parapet walls, eaves and other parts of the structure will be greatly damaged. Therefore, a railing slot pre-embedded part is proposed.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Design a railing slot pre-embedded part, including a support plate and through holes. The support plate has four through holes inside. A slot plate is fixed to the upper surface of the support plate. The slot plate has a strip groove and an arc groove inside. The strip groove and the arc groove are connected. The support plate has four threaded holes inside. The threaded holes are threaded to the outer wall of the threaded column.

[0008] Preferably, the threaded column is fixedly connected to one end of the reinforcing bar, and the strip groove is clearance-fitted with the outer wall of the screw.

[0009] Preferably, a nut is fixed to the lower end of the screw, and a first washer is attached to the upper part of the nut.

[0010] Preferably, the first washer is clearance-fitted with the outer wall of the screw, and the upper surface of the first washer is in contact with the slot plate.

[0011] Preferably, a nut is threaded onto the outer wall of the screw, and a second washer is fixed below the nut, with the second washer having a clearance fit with the outer wall of the screw.

[0012] Preferably, the diameters of both the second gasket and the first gasket are greater than the width of the strip groove.

[0013] Preferably, the diameter of the second gasket is smaller than the inner diameter of the arc groove.

[0014] The present invention proposes a pre-embedded railing slot, which has the following advantages: The through hole inside the railing passes through the outer wall of the screw rod, with the upper part of the screw rod protruding to the outside of the railing. When the nut is screwed onto the outer wall of the screw rod, its vertical position changes during rotation, causing the nut to move the second washer. The second washer fits tightly against the railing, and the first washer fits tightly against the slot plate. The railing is then placed on the embedded part and fixed to the slot plate by the screw rod, nut, first washer, nut, and second washer. The reinforcing steel is embedded in the structure. The pre-embedded part avoids damage to the structure during construction. Furthermore, the railing, connected by the screw rod, nut, first washer, nut, and second washer, can be easily removed and reused. This method is less likely to damage the structure and will not cause significant damage to small parapet walls, eaves, or other structural components. Attached Figure Description
