High-performance precast concrete components

Abstract

This utility model discloses a high-performance precast concrete component, including a slab mechanism and a rust-proof mechanism. The slab mechanism includes a concrete slab and multiple reinforcing bars, each of which transversely penetrates both ends of the concrete slab. The rust-proof mechanism includes two protective shells slidably fitted onto both ends of the concrete slab, and multiple sliders slidably connected to the top and bottom surfaces of the inner sides of the protective shells. After aligning the protective shells with the ends of the reinforcing bars, the protective shells are connected to the concrete slab. Then, the protective shells are screwed onto the protective shells to provide initial protection for the ends of the reinforcing bars. Next, the cap is opened, and a corrosion-inhibiting gel or vapor-phase rust inhibitor is filled into the protective shells to achieve long-term sealing protection for the ends of the reinforcing bars. Finally, a one-way breather valve is activated to effectively block the intrusion of external liquid water and chloride ions while expelling internal moisture, keeping the ends dry. Through these operations, the risk of rust at the ends of the reinforcing bars can be significantly reduced.

Description

Technical Field

[0001] This utility model relates to the field of precast concrete components, specifically high-performance precast concrete components. Background Technology

[0002] The ends of the reinforcing bars in precast components are critical parts for subsequent connections and are the weakest link and primary risk point for corrosion prevention. After production, they are often directly exposed to the air. During storage, transportation, and hoisting, they are not only subject to long-term corrosive media such as environmental moisture and salt, but also easily damaged by mechanical actions such as bumps and friction.

[0003] The currently commonly used temporary anti-rust paint protection method has disadvantages such as limited adhesion, easy damage to the paint film, and short anti-rust period. It is difficult to provide continuous and effective protection before the components are installed, thus creating hidden dangers of rust and directly affecting the durability of the structure and the safety of the connection.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0030] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0031] The following describes some embodiments of the high-performance precast concrete components provided by this utility model with reference to the accompanying drawings.

[0032] Example 1:

[0033] Combination Figure 1-7 As shown, the high-performance precast concrete component provided by this utility model includes a slab mechanism 100 and a rust prevention mechanism 200. The slab mechanism 100 includes a concrete slab 110 and a plurality of steel bars 120, all of which transversely penetrate both ends of the concrete slab 110.

[0034] The rust prevention mechanism 200 includes two protective shells 210 that are slidably sleeved at both ends of the concrete slab 110, a plurality of sliders 220 that are slidably connected to the inner top and inner bottom surfaces of the protective shells 210, a sleeve plate 230 that is movably sleeved on the outside of the reinforcing bar 120 and slidably connected between the two opposing sliders 220, a protective sleeve 240 that is screwed to the sleeve plate 230, a cap 250 that is screwed to the top of the protective sleeve 240, and a one-way breather valve 260 installed on the protective sleeve 240.

[0035] Furthermore, the inner top and bottom surfaces of the protective shell 210 are provided with grooves suitable for the sliding of the slider 220. The vertical cross-section of the groove is set to T-shape. The structural design of the groove effectively prevents the slider 220 from falling off.

[0036] Furthermore, the sheath 240 is movably sleeved on the outer end of the reinforcing bar 120. The sheath 240 is composed of a rear end shell 241, a rotating shell 242, and a front cover 243. The rotating shell 242 is screwed between the rear end shell 241 and the front cover 243. The rear end shell 241 is screwed to the sleeve plate 230. The structural design of the sheath 240 allows it to be flexibly disassembled into three sections after removal, providing conditions for completely cleaning the corrosion-inhibiting gel or vapor phase rust inhibitor inside, and facilitating the recycling of the sheath 240.

[0037] Furthermore, the cap 250 and the one-way breather valve 260 are vertically coaxial, with the cap 250 located at the top of the shell 242 and the one-way breather valve 260 located at the bottom of the shell 242. The layout design of the cap 250 and the one-way breather valve 260 ensures that the filling operation of the corrosion-inhibiting gel or vapor phase rust inhibitor and the water vapor discharge operation do not interfere with each other, greatly improving the structural stability of the device.

[0038] Furthermore, a sealing gasket 400 is fitted inside the sleeve 230. The sealing gasket 400 is tightly fitted to one end wall of the concrete slab 110. The sealing gasket 400 can seal the gap between the sleeve 240 and the end wall of the concrete slab 110, thereby improving the protective effect of the sleeve 240 on the end of the reinforcing bar 120.

[0039] Example 2:

[0040] Combination Figure 1 , 2 and Figure 7As shown, based on Embodiment 1, a protective component 300 is provided on the outer side of the concrete slab 110. The protective component 300 includes four supports 310 surrounding the outer side of the protective shell 210, a crossbar 320 slidably connected between two opposing supports 310, and multiple nuts 330 screwed to the outer end of the crossbar 320. The supports 310, crossbar 320, and nuts 330 cooperate with each other to protect the concrete slab 110 and effectively reduce the probability of damage to the concrete slab 110 due to collision.

[0041] Example 3:

[0042] Combination Figure 1-2 As shown, in the above embodiment, four reinforcing ribs are fixedly connected between the support 310 and the protective shell 210. The four reinforcing ribs are located on both sides of the support 310. The reinforcement ribs can improve the connection between the support 310 and the protective shell 210.

[0043] The working principle and usage process of this utility model are as follows: When this device is put into actual use, firstly, adjust the position of multiple sliders 220 along the slide groove so that the sleeve plate 230 between two opposing sliders 220 is horizontally aligned and coaxial with the reinforcing bar 120. Then, move the sleeve plate 230 up and down so that it can be smoothly fitted onto the outside of the reinforcing bar 120. Next, fit the protective shell 210 onto the outside of the concrete slab 110 and tighten the protective sleeve 240 and the sleeve plate 230 to achieve initial protection of the end of the reinforcing bar 120.

[0044] Next, open the cap 250 and fill the sleeve 240 with corrosion-inhibiting gel or vapor phase rust inhibitor to achieve long-term sealing protection for the end of the rebar 120. Finally, activate the one-way breather valve 260 to effectively block the intrusion of external liquid water and chloride ions while expelling internal moisture, keeping the end dry. Through the above operations, the risk of rust on the end of the rebar 120 can be significantly reduced.

[0045] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
