Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building materials, and particularly relates to a fully concealed structural floor supporting bar for reinforcing bars. Background Art
[0002] In the existing construction field, the problem of rust return of the structural floor supporting bar for reinforcing bars often occurs, and the rust return of the supporting bar for reinforcing bars has a great influence on the appearance quality of the formed structure. At present, there are three forms of the existing structural floor supporting bar for reinforcing bars: linear finished steel supporting bars for reinforcing bars, point-shaped finished steel supporting bars for reinforcing bars, and on-site simple processed "U-shaped" supporting bars for reinforcing bars.
[0003] Linear and point-shaped finished steel supporting bars for reinforcing bars: Most of the finished supporting bars for reinforcing bars in the construction market are steel leg-type supporting bars for reinforcing bars, and the leg parts of the supporting bars for reinforcing bars are coated with antirust paint to prevent rusting of the leg parts. When installing the supporting bar for reinforcing bars, the leg of the supporting bar for reinforcing bars is in direct contact with the formwork. During the installation of the reinforcing bars and the pouring of concrete, due to the trampling of personnel walking, on-site handling, etc., the antirust coating on the leg part is damaged. After the floor slab is poured and formed, the end of the leg of the supporting bar for reinforcing bars will be exposed on the surface layer of the floor slab. Under the action of curing water, moisture, etc., after a period of time, the problem of rusting of the leg of the supporting bar for reinforcing bars will inevitably occur.
[0004] On-site simple processed supporting bar for reinforcing bars: For the on-site simple processed "U-shaped" supporting bar for reinforcing bars, due to the failure to do a good job in rust prevention of the legs, the problem of rusting of the reinforcing bars often occurs, and the point-shaped support is unstable, and the control effect on the steel bar protective layer is poor. Summary of the Invention
[0005] In order to solve the problems in the prior art, the utility model patent designs a fully concealed structural floor supporting bar for reinforcing bars to solve the problems that the end of the leg of the existing structural floor supporting bar for reinforcing bars is exposed during use, resulting in serious rust return problems and unsatisfactory application effects.
[0006] The technical solution adopted by the utility model is that the supporting bar for reinforcing bars includes a first reinforcing bar and a second reinforcing bar which are arranged in parallel up and down, the first reinforcing bar and the second reinforcing bar are bent at the same angle, and a plurality of groups of V-shaped web members are welded between the first reinforcing bar and the second reinforcing bar.
[0007] Further, the first reinforcing bar and the second reinforcing bar are respectively bent into the same acute angle shape with their respective centers as vertices.
[0008] Further, the angle of the included angle formed by the bending of the first reinforcing bar and the second reinforcing bar is 45° - 60°.
[0009] Further, the first reinforcing bar is located on the upper side, the second reinforcing bar is located on the lower side, and the open end of the V-shaped web member is arranged downward and is welded and fixed to the second reinforcing bar.
[0010] Further, a total of 4 sets of V-shaped web members are welded between the first steel bar and the second steel bar, and two sets of V-shaped web members are welded on each side of the bending angle of the first steel bar and the second steel bar respectively.
[0011] Further, the distance from the two web members near the bending vertex of the second steel bar to the bending vertex is 50 mm, and the distance from the two web members near the two ends of the second steel bar to the ends is also 50 mm.
[0012] Further, the first steel bar, the second steel bar and the web members are all deformed steel bars.
[0013] Compared with the prior art, the improvement of a fully concealed structure floor support bar designed by the utility model patent lies in that: the support bar is provided with upper and lower first steel bars and second steel bars. During use, steel bar layers are respectively tied on the upper and lower sides to form a steel bar support structure. When concrete is poured, the support bar is located between the upper and lower two-layer steel bar structure layers and will not be in direct contact with the outer support formwork. After the concrete pouring is completed, the support bar will not be exposed, avoiding the rusting of the support bar. The first and second steel bars are bent at acute angles, and a V-shaped web member is used for support between them, making its structure firm and stable, and it is made of deformed steel bars, making the overall strength of the support bar relatively high. The V-shaped web members are arranged at intervals, saving the overall material of the support bar and reducing the construction cost on the basis of ensuring sufficient support strength. Description of the Drawings
[0014] Figure 1 It is a schematic structural diagram of a fully concealed structure floor support bar.
[0015] In the figure, 1 is the first steel bar, 2 is the second steel bar, and 3 is the web member. Detailed Embodiments
[0016] The following further describes the present utility model with reference to the drawings and specific embodiments. The technical solutions in the embodiments of the present utility model are clearly and completely described. The described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0017] As Figure 1 shown, an embodiment of a fully concealed structure floor support bar is designed in the utility model patent. In this embodiment, the support bar includes a first steel bar 1 and a second steel bar 2 arranged in parallel up and down, where the first steel bar 1 is located on the upper side and the second steel bar 2 is located on the lower side, and 4 sets of V-shaped web members 3 are welded between the first steel bar 1 and the second steel bar 2.
[0018] The first steel bar 1 and the second steel bar 2 are respectively bent into the same acute angle shape with their respective centers as vertices, and the angle of the formed included angle is 60°. When welding the V-shaped web member 3, the open end is at the bottom and welded and fixed to the second steel bar 2, and the other end is welded and fixed to the first steel bar 1. When arranging the 4 groups of V-shaped web members 3, two groups are respectively arranged on both sides of the bending vertices of the first steel bar 1 and the second steel bar 2. The two groups of V-shaped web members 3 close to the bending vertex side of the second steel bar 2 are both about 50 mm away from the bending fixed point, and the other two groups of V-shaped web members 3 are both 50 mm away from the end of the second steel bar 2.
[0019] When manufacturing the full-concealed structure floor support bar disclosed in the utility model patent, threaded steel is used for cutting and manufacturing. First, threaded steel with the same length of about 800 mm at both ends is intercepted as the first steel bar and the second steel bar, and a bending machine is used to bend them into a 60° included angle shape with the center point as the bending point respectively. Then, 8 sections of 100 mm threaded steel are intercepted and welded in pairs into a V shape to manufacture the V-shaped web member. The bent first steel bar and the second steel bar are respectively placed on the welding fixture, and the V-shaped web member is welded between them. When welding, pay attention to the distances between the web members at both ends and the bending vertex and the end of the second steel bar. At the same time, it is necessary to ensure that the V-shaped web members are all welded on the same vertical plane to avoid distortion.
[0020] The above content is only the preferred embodiment of the present invention, and the scope of implementation of the present invention cannot be limited thereby. That is, all simple equivalent changes and modifications made according to the claims of the present invention and the description content of the invention still fall within the scope covered by the present invention.
