Description

Technical Field

[0001] This utility model relates to the field of construction, and in particular to a control device for the protective layer of reinforcement bars in large cross-section beams. Background Technology

[0002] Compared to ordinary concrete structures, the construction technology of large-section beams stems from the increasing demands of modern architecture for greater spatial span, structural safety, and construction efficiency, especially in complex projects such as high-rise building transfer floors, long-span bridges, and stadiums. Its development is driven by innovations in materials science, structural mechanics, and construction techniques, but it also faces challenges such as environmental adaptability and construction precision control. The dense reinforcement at the beam-column joints of large-section beams makes it difficult to position prestressed corrugated pipes and openings in the web of steel columns, easily leading to construction conflicts and rework.

[0003] Currently, in most construction projects, large-span structures have large-diameter steel bars with dense reinforcement and heavy steel cages, making them prone to sinking or lateral displacement during binding and pouring. The steel bars at large-span beam-column joints and intersections of prestressed and non-prestressed tendons are complex and difficult to control precisely, resulting in local protective layers that are too thin or too thick. Large-span beam reinforcement is not convenient to be directly bound and should be pre-formed into a steel cage for subsequent overall hoisting, which also relies heavily on stable steel support. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a control device for the protective layer of large cross-section beam reinforcement, which is beneficial to first form the beam reinforcement skeleton, and then install concrete pads on the beam reinforcement skeleton. After the beam reinforcement skeleton is hoisted, the concrete pads separate the beam reinforcement skeleton from the formwork to control the thickness of the concrete beam protective layer.

[0005] To solve the above problems, a large-section beam reinforcement protective layer control device is adopted, which includes: The first support includes a first base, a first upright mounted on the first base, a first horizontal bar horizontally mounted on the first upright, and a first rod head mounted on the first horizontal bar, coaxial with the first upright and having the same diameter; The second support includes a second base, a second upright mounted on the second base, a second horizontal bar horizontally mounted on the second upright, and a second rod head mounted on the second horizontal bar and coaxial with the second upright and having the same diameter. The first horizontal bar and the second horizontal bar have the same diameter and are coaxially connected. The disc buckle is fixedly installed on the first pole head and the second pole head; and is spaced vertically on the first upright and the second upright, and has a pin hole; The pressure plate is closely attached to the disc buckle on the first and second rod heads and is pressed against the upper longitudinal rib. The pressure plate has pin holes spaced apart, and the pin holes at both ends correspond to the pin holes of the disc buckle. The pin head is inserted into the pin hole of the disc buckle on the first and second pole heads and the lowest disc buckle on the first and second poles, and passes through the pin opening at the end of the pressure plate and abuts against the upper and lower longitudinal ribs on the side; it is inserted into the pin opening in the middle of the pressure plate and abuts against the upper and lower longitudinal ribs; it is inserted into the pin hole of the disc buckle on the first and second poles and abuts against the waist rib. Concrete spacers are fixed to the bottom of the bottom longitudinal reinforcement by tying wires.

[0006] With this structure, after the beam reinforcement cage is formed, the first and second supports can be separated to the left and right, detached from the beam reinforcement cage, which facilitates the hoisting of the beam reinforcement cage; the pin head is inserted into the disc buckle or into the pressure plate, which facilitates the positioning of the longitudinal reinforcement; the disc buckle is conducive to adjusting the position and then positioning with the upright and the pole head, which makes it easy to determine the installation position of the longitudinal reinforcement, so as to improve the forming accuracy of the steel reinforcement cage.

[0007] As a further improvement of this utility model, the first base and the second base are channel steel; they are slidably assembled on the convex pad strip.

[0008] With this structure, the convex pads help to support the channel steel and also facilitate the sliding of the channel steel for stable detachment.

[0009] As a further improvement of this utility model, a first hinge support is installed on the first upright; a second hinge support is installed at the intersection of the second upright and the second crossbar; the first hinge support is hinged to one end of the first screw; the second hinge support is hinged to the second screw; the first screw and the second screw are connected by a straight threaded sleeve.

[0010] With this structure, the first screw and the second screw are connected by a straight threaded sleeve, which can pull the first bracket and the second bracket together to ensure that the first bracket and the second bracket will not detach from each other during use.

[0011] As a further improvement of this utility model, square steel pipes are installed on both sides of the convex pad strip, and the concrete pad block is placed on the square steel pipes.

[0012] With this structure, the square steel pipe is placed exactly underneath the concrete block; As a further improvement of this utility model, the top surface of the concrete pad has a recess, which is adapted to the bottom of the bottom longitudinal reinforcement.

[0013] This structure increases the contact area and prevents the concrete pad from sliding.

[0014] As a further improvement of this utility model, the concrete pad is provided with through holes for the binding wire to pass through.

[0015] With this structure, the concrete spacers are easier to tie after being connected by wire, ensuring that the concrete spacers do not detach from the beam reinforcement skeleton. This allows them to be placed directly on the bottom formwork of the beam after subsequent hoisting, separating the beam reinforcement skeleton from the bottom formwork to control the thickness of the bottom protective layer. The concrete spacers can then be poured together with the beam reinforcement skeleton to form a whole. The concrete spacers can also be installed along the side longitudinal bars and stirrups to control the thickness of the side protective layer of the beam.

[0016] This invention facilitates the formation of a beam reinforcement skeleton first, and the installation of concrete pads on the beam reinforcement skeleton. After the beam reinforcement skeleton is hoisted, the concrete pads separate the beam reinforcement skeleton from the formwork, thereby controlling the thickness of the concrete beam protective layer.

[0023] Example 1 like Figures 1-3 As shown, a control device for the protective layer of reinforcement in large cross-section beams includes: The first support 1 includes a first base 101, a first upright 102 mounted on the first base 101, a first horizontal bar 103 horizontally mounted on the first upright 102, and a first rod head 104 mounted on the first horizontal bar 103, coaxial with the first upright 102 and having the same diameter; The second support 2 includes a second base 201, a second upright 202 mounted on the second base 201, a second horizontal bar 203 horizontally mounted on the second upright 202, and a second rod head 204 mounted on the second horizontal bar 203 and coaxial with the second upright 202 and having the same diameter. The first horizontal bar 103 and the second horizontal bar 203 have the same diameter and are coaxially connected. The disc buckle 3 is fixedly mounted on the first rod head 104 and the second rod head 204; and is spaced vertically on the first upright 102 and the second upright 202, and has a pin hole 301. The pressure plate 4 is closely attached to the disc buckle 3 on the first rod head 104 and the second rod head 204, and is pressed against the upper longitudinal rib 5. The pressure plate 4 has a series of pin holes 401, and the pin holes 401 at both ends correspond to the pin holes 301 of the disc buckle 3. The pin head 6 is inserted into the disc buckle 3 on the first rod head 104 and the second rod head 204, and into the pin hole 301 of the lowest disc buckle 3 on the first upright 102 and the second upright 202. It also passes through the pin opening 401 at the end of the pressure plate 4 and abuts against the upper longitudinal rib 5 and the bottom longitudinal rib 13 on the side. The pin head 6 is inserted into the pin opening 401 in the middle of the pressure plate 4 and abuts against the upper longitudinal rib 5 and the bottom longitudinal rib 13. The pin head 6 is inserted into the pin hole 301 of the disc buckle 3 on the first upright 102 and the second upright 202 and abuts against the waist rib 7. The concrete pad 8 is fixed to the bottom of the bottom longitudinal reinforcement 13 by tying wire 9.

[0024] With this structure, after the beam reinforcement cage is formed, the first support 1 and the second support 2 can be separated to the left and right, detached from the beam reinforcement cage, which facilitates the hoisting of the beam reinforcement cage; the pin head 6 is inserted into the disc buckle 3 or into the pressure plate 4, which facilitates the positioning of the longitudinal reinforcement; the disc buckle 3 is conducive to adjusting the position and then positioning with the upright and the pole head, which makes it easy to determine the installation position of the longitudinal reinforcement, so as to improve the forming accuracy of the steel reinforcement cage.

[0025] In this embodiment, the first base 101 and the second base 201 are channel steels; they are slidably assembled on the convex pad strip 10.

[0026] With this structure, the convex pad 10 is beneficial for supporting the channel steel and also facilitates the sliding of the channel steel to ensure stable detachment.

[0027] In this embodiment, a first hinge support 105 is installed on the first upright 102; a second hinge support 205 is installed at the intersection of the second upright 202 and the second crossbar 203; the first hinge support 105 is hinged to one end of the first screw 106; the second hinge support 205 is hinged to the second screw 206; the first screw 106 and the second screw 206 are connected by a straight threaded sleeve 11.

[0028] With this structure, the first screw 106 and the second screw 206 are connected by a straight threaded sleeve 11, which can pull the first bracket 1 and the second bracket 2 together to ensure that the first bracket 1 and the second bracket 2 will not detach from each other during use. When disassembling, the straight threaded sleeve 11 is rotated to disengage from one of the screws, thereby releasing the limit between the first bracket and the second bracket.

[0029] In this embodiment, square steel pipes 12 are installed on both sides of the convex pad strip 10, and the concrete pad block 8 is placed on the square steel pipe 12.

[0030] With this structure, the square steel pipe 12 is placed exactly under the concrete pad 8; In this embodiment, the top surface of the concrete pad 8 has a recess 801, which is adapted to the bottom of the bottom longitudinal reinforcement 13.

[0031] This structure increases the contact area and prevents the concrete pad 8 from sliding.

[0032] In this embodiment, the concrete pad 8 has a through hole 802 for the binding wire 9 to pass through.

[0033] With this structure, the tie wire 9 is easier to tie after being threaded through the concrete pad 8, so that the concrete pad will not detach from the beam reinforcement skeleton. This makes it easier to place the entire structure on the bottom formwork of the beam after subsequent hoisting, so that the beam reinforcement skeleton is directly separated from the bottom formwork of the beam, thereby controlling the thickness of the protective layer at the bottom of the beam. The concrete pad 8 can be poured together with the beam reinforcement skeleton to form a whole. The concrete pad 8 can also be installed along the side longitudinal bars and stirrups to control the thickness of the protective layer on the side of the beam.

[0034] This invention facilitates the formation of a beam reinforcement skeleton first, and the installation of concrete pads on the beam reinforcement skeleton. After the beam reinforcement skeleton is hoisted, the concrete pads separate the beam reinforcement skeleton from the formwork, thereby controlling the thickness of the concrete beam protective layer.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several equivalent substitutions or obvious modifications can be made without departing from the concept of the present invention, and all such modifications, with identical performance or use, should be considered within the protection scope of the present invention.
