Abstract
Description
Technical Field
[0001] The utility model relates to the field of building construction, in particular to a concrete reinforcement locking device for reinforcement construction. Background Art
[0002] In highway engineering, bridges, tunnels, and various other structures, large quantities of formwork reinforcement, top reinforcement, and protective reinforcement are added to the concrete to improve the qualified rate of the steel reinforcement cover. These reinforcements play a positive role in improving the accurate positioning of the main reinforcement skeleton. However, because these reinforcements are located on the concrete surface, they are often exposed, making them more susceptible to corrosion and damage to the concrete.
[0003] Because some special structures in concrete construction have to use steel bars, these steel bars are often cut by the concrete surface and are directly exposed to the natural environment of air, which can easily rust and cause concrete damage, thereby reducing the durability of concrete. Utility Model Content
[0004] The purpose of this utility model is to provide a concrete reinforcement locking device for steel bar construction, which is used to solve the problem that the reinforcement bars used in some special structures in existing concrete construction are often directly exposed to the air and natural environment, which easily corrodes and causes concrete damage, thereby reducing the durability of the concrete.
[0005] To achieve the above-mentioned purpose, the utility model provides a concrete reinforcement locking device for steel bar construction, which is installed on a concrete pouring formwork and includes:
[0006] A reinforcement sleeve is inserted into a mounting hole on a casting template. One end of the reinforcement sleeve is provided with a positioning hole on the inner side of the casting template. The inner diameter of the positioning hole is adapted to the outer diameter of the reinforcement. The positioning hole is provided with an internal thread for engaging the end of the reinforcement. The other end of the reinforcement sleeve is provided with an external thread.
[0007] The grout stop washer is installed on the outside of the casting formwork and has a connecting hole in its center for the reinforcement sleeve to pass through;
[0008] The locking nut is screwed onto the external thread at the outer end of the reinforcement sleeve to press the stop washer against the outer side of the casting formwork;
[0009] The sealing block is used to seal the concrete holes left after the reinforcement sleeve is removed after the concrete pouring is completed.
[0010] As a further solution of the present invention, a backing plate is installed at the contact end surface between the locking nut and the slurry stop washer.
[0011] As a further solution of the present invention, the blocking block is fixed and adhered to the concrete hole by adhesive.
[0012] Compared with the existing technology, this patent designs the reinforcement sleeve, grout-stopping washers, locking nuts and sealing blocks, which can bear the force together with the reinforcement, better reinforce the concrete formwork, and the grout-stopping washers seal the leakage of grout in the reinforcement holes, so that the concrete reinforcement is no longer exposed, solving the problem that the reinforcement used in some special structures in existing concrete construction is often directly exposed to the natural environment of air, which easily rusts and causes damage to the concrete, reducing the durability of the concrete.

[0016] The technical solution of the present utility model will be further described in detail below in conjunction with specific implementation methods.
[0017] like Figure 1 and Figure 2 As shown, in the embodiment of the present utility model, a concrete reinforcement locking device for steel bar construction is installed on the concrete casting template 2, including a reinforcement sleeve 4, which is used to be inserted into the installation hole opened on the casting template 2, and the reinforcement sleeve 4 is inserted into the casting template 2. One end of the reinforcement sleeve 4 is provided with a positioning hole on the inner side of the casting template 2, and the inner diameter of the positioning hole is adapted to the outer diameter of the reinforcement 3. The positioning hole is provided with an internal thread that engages the end of the reinforcement 3, and the other end of the reinforcement sleeve 4 is provided with an external thread; a grouting washer 5 is installed on the outer side of the casting template 2, and a connecting hole for the reinforcement sleeve 4 to pass through is provided in the center; a locking nut 6 is rotatably installed at the external thread on the outer end of the reinforcement sleeve 4, and is used to press the grouting washer 5 to the outside of the casting template 2; a blocking block 8 is used to block the hole in the concrete 1 left after the reinforcement sleeve 4 is removed after the concrete 1 is poured;
[0018] Specifically, in the present invention, the reinforcement sleeve 4 is tightened with one end of the reinforcement 3 to form a closed structure, and the locking cap is an extended nut, which is screwed into one end of the reinforcement sleeve 4 to tighten the concrete 1 template 2. At the same time, the locking cap can be tightened manually with an electric wrench or a tool. The slurry-stopping gasket 5 is a rubber ring structure, which is used to seal the gap between the template 2 and the reinforcement sleeve 4 to prevent leakage of concrete 1. The hole sealing block 8 of concrete 1 is used to seal the hole after the reinforcement sleeve is removed, which solves the problem of inconsistent color of the concrete 1 after sealing and contamination of the surrounding concrete 1 surface.
[0019] Furthermore, a backing plate 7 is installed at the contact end surface between the locking nut 6 and the grout-stopping washer 5. When the reinforcement sleeve 4 is tightened, the backing plate 7 is driven to squeeze the grout-stopping washer 5 to deform and realize sealing.
[0020] like Figure 2 As shown, in the embodiment of the present utility model, the blocking block 8 is fixed and adhered to the hole of the concrete 1 by adhesive, so as to seal the hole after casting.
[0021] Compared with the existing technology, this patent designs the tie rod sleeve 4, the grout-stopping washer 5, the locking nut 6 and the blocking block 8, which can bear the force together with the tie rod 3, better reinforce the concrete 1 template 2, and the grout-stopping washer 5 seals the leakage of the tie rod 3 holes, so that the concrete 1 tie rod 3 is no longer exposed, solving the problem that the tie rod 3 used in some special structures in the existing concrete 1 construction is often directly exposed to the air and natural environment, which is easy to rust and cause damage to the concrete 1, thereby reducing the durability of the concrete 1.
[0022] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
