Description

Technical Field

[0001] The present application relates to the technical field of steel bar protective layer pads, and in particular to a concrete support member, a manufacturing mold and a manufacturing method. Background Art

[0002] Rebar cover thickness refers to the thickness of the concrete from the outer edge of the stressed reinforcement to the outer surface of the concrete. In concrete structures, the quality of the rebar cover directly impacts the structure's load-bearing capacity, durability, and fire resistance. Traditionally, cast-in-place side wall concrete cover thickness control components primarily consist of concrete pads or circular plastic pads, which are tied to the side wall reinforcement at regular intervals.

[0003] However, in the actual construction process, traditional pads often have problems such as loose binding, displacement and damage due to vibration during pouring, which leads to poor control accuracy of the overall protective layer thickness. Summary of the Invention

[0004] In order to improve the current control accuracy of the thickness of the steel bar protective layer, the present application provides a concrete support member, a manufacturing mold and a manufacturing method.

[0005] In a first aspect, the present application provides a concrete support member, which adopts the following technical solution:

[0006] A concrete support member includes a member body, which is arranged on a transverse steel bar in a direction perpendicular to the wall thickness. A plurality of transverse steel bar positioning grooves are provided on the member body along the length direction, and the spacing between two adjacent transverse steel bar positioning grooves is consistent with the spacing between two adjacent transverse steel bars. The member body is also provided with a plurality of vertical steel bar positioning grooves for placing vertical steel bars, and the transverse steel bar positioning grooves are connected to the vertical steel bar positioning grooves to accommodate the binding steel wires between the transverse steel bars and the vertical steel bars.

[0007] By adopting the above technical solution, the steel mesh is composed of a combination of transverse and vertical steel bars. The transverse steel bars are clamped in the transverse steel bar positioning grooves of the component body, and the vertical steel bars are clamped in the vertical steel bar positioning grooves of the component body. Because the transverse and vertical steel bar positioning grooves provided in the component body are connected, the steel wire used for binding can be clamped between the transverse and vertical steel bar positioning grooves without interference.

[0008] Optionally, two of the transverse steel bar positioning grooves and two of the vertical steel bar positioning grooves are provided, and the two vertical steel bar positioning grooves are distributed on both sides of the component body.

[0009] By adopting the above technical solution, two vertical steel bar positioning grooves are distributed on both sides of the component body. After the two vertical steel bars are inserted into the two corresponding vertical steel bar positioning grooves, they are restricted on both sides and are not easy to escape from the groove direction of the vertical steel bar positioning grooves, which can improve the stability during concrete pouring and vibration.

[0010] Optionally, both of the two vertical steel bar positioning grooves are arc-shaped grooves for the vertical steel bars to rotate into.

[0011] By adopting the above technical solution, by setting the vertical steel bar positioning groove as an arc groove, when using the supporting member, the member body can be first placed obliquely between the two vertical steel bars, and then the member body can be rotated to make the vertical steel bars fall into the vertical steel bar positioning groove, and then the member body can be placed downward on the transverse steel bars, and the transverse steel bars fall into the transverse steel bar positioning groove to achieve the positioning of the member body.

[0012] Optionally, the bottoms of the two vertical steel bar positioning grooves are on the same straight line in the length direction of the component body.

[0013] By adopting the above technical solution, the vertical steel bar positioning grooves are in the same straight line, which can keep the length direction of the component body aligned with the thickness direction of the wall when in use.

[0014] Optionally, a connecting groove connecting the two vertical steel bar positioning grooves is provided on the component body along the length direction.

[0015] By adopting the above technical solution, since the main body of the component will not be removed when pouring the wall, the concrete can enter the connecting groove through the setting of the connecting groove, thereby wrapping the steel bar and improving the stability of the main body of the component.

[0016] Optionally, two reinforcing steel bars are embedded in the component body, the length direction of the two reinforcing steel bars is consistent with the length direction of the component body, and the two reinforcing steel bars are respectively arranged on the sides of the two vertical steel bar positioning grooves.

[0017] By adopting the above technical solution, the reinforcing steel bars are located on the sides of the vertical steel bar positioning grooves, which can reduce the weakening of the structural strength of the component body after the grooves are opened.

[0018] In a second aspect, the present application provides a mold for manufacturing a concrete support member, which adopts the following technical solution:

[0019] A manufacturing mold includes a first side panel and a second side panel relative to each other, and two positioning blocks arranged at both ends of the first side panel and the second side panel, the two positioning blocks, together with the first side panel and the second side panel, form a forming interval for the concrete support member, the first side panel and the second side panel are both provided with vertical tenons for forming the vertical steel bar positioning grooves and transverse tenons for forming the transverse steel bar positioning grooves, the vertical tenons and the transverse tenons are abutted together, when the first side panel and the second side panel are brought close to each other, the transverse tenons on the first side panel are abutted against the second side panel, and the transverse tenons on the second side panel are abutted against the first side panel.

[0020] By adopting the above technical solution, a forming area can be enclosed by the first side panel, the second side panel and the two positioning blocks. After the concrete is poured into the forming area and vibrated, the top is scraped flat to form a supporting member. Since the setting of the vertical tenon block and the transverse tenon block can correspond to the formed vertical steel bar positioning groove and the transverse steel bar positioning groove, and since the vertical tenon block and the transverse tenon block are close to each other, the formed vertical steel bar positioning groove and the transverse steel bar positioning groove will remain connected, so that the transverse steel bar and the vertical steel bar can be inserted and the steel wire used for binding can be accommodated.

[0021] Optionally, it further includes a bottom plate and two positioning scrapers, wherein the bottom plate is provided with convex strips along the length direction, and the convex strips are provided with recesses for avoiding the vertical tenons.

[0022] By adopting the above technical solution, the convex strips on the bottom plate can be used to form the connecting grooves on the main body of the component. At the same time, because of the clearance grooves provided on the convex strips, when the vertical tenons on the first side plate and the second side plate are inserted into the clearance grooves, the positions of the first side plate and the second side plate can be positioned.

[0023] In a third aspect, the present application provides a method for manufacturing a concrete support member, which adopts the following technical solution:

[0024] A method for manufacturing a concrete support member, for manufacturing the concrete support member, is provided by manufacturing a mold, wherein the mold includes a first side panel and a second side panel facing each other, and two positioning blocks provided at both ends of the first side panel and the second side panel, wherein the first side panel is provided with a vertical tenon block for forming the vertical steel bar positioning groove, and the second side panel is provided with a transverse tenon block for forming the transverse steel bar positioning groove, and the method comprises the following specific steps:

[0025] S1. Enclose the first side panel, the second side panel, and two positioning blocks to form a forming area;

[0026] S2. Positioning the first side panel, the second side panel, and the two positioning blocks;

[0027] S3, pouring concrete into the forming area;

[0028] S4. Vibrate the concrete and smooth the concrete above the forming area.

[0029] By adopting the above technical solution, a positioning interval is formed by enclosing the first side panel, the second side panel and the two positioning blocks. The first side panel, the second side panel and the positioning blocks can all be made of wooden blocks, which is very low in cost. After pouring concrete into the forming interval and scraping it flat, the supporting member can be formed. It can be directly manufactured on site, the manufacturing method is simple, and no additional tools are required.

[0030] Optionally, in S2, the first side panel and the second side panel are positioned by a positioning scraper, the positioning scraper having an inverted U-shaped structure, including two limiting rod portions located on both sides and a scraper portion located above, when the first side panel and the second side panel are brought together, the two limiting rod portions are located outside the first side panel and the second side panel to limit the first side panel and the second side panel from separating, and the scraper portion is located above the first side panel and the second side panel;

[0031] In S4, the positioning scraper is moved to level the concrete above the forming area.

[0032] By adopting the above technical solution, the scraper is set in a U-shaped structure. When setting up the mold, two scrapers can be set. The two scrapers are respectively located at the positions of the positioning blocks outside the first side plate and the second side plate. In this way, the separation of the positioning blocks and the first side plate and the second side plate can be avoided during the pouring and vibration process.

[0033] In summary, this application has at least one of the following beneficial effects:

[0034] 1. The vertical steel bars and transverse steel bars can be respectively stuck in the vertical steel bar positioning groove and the transverse steel bar positioning groove, which can improve the stability of the vertical and transverse steel bars after binding and avoid deviation during the pouring process;

[0035] 2. Two vertical steel bar positioning grooves are located on both sides to prevent the vertical steel bars from falling out of the grooves during the pouring process;

[0036] 3. The setting of the connecting groove not only enhances the stability of the supporting member after the concrete is poured, but also allows a protrusion to be set on the bottom plate of the mold, and a clearance groove to be opened on the protrusion to position the first side plate and the second side plate;

[0037] 4. The scraper not only flattens the surface of the support member when forming the support member, but can also be placed as a positioning structure on both sides of the positioning block position to avoid separation of the first side plate and the second side plate during the pouring process.

DETAILED DESCRIPTION

[0046] The following is combined with Figure 1-7 This application is described in further detail.

[0047] Example 1

[0048] Reference Figure 1 and Figure 2The embodiment of the present application discloses a concrete support member, including a member body 1 that is generally in the shape of a rectangular parallelepiped. The length of the member body 1 is greater than the distance between two horizontal transverse steel bars 4. At the same time, two transverse steel bar positioning grooves 12 are provided on the member body 1 along the width direction. The distance between the two transverse steel bar positioning grooves 12 is consistent with the distance between the transverse steel bars 4. When in use, the support member can be placed above the two transverse steel bars 4 so that the transverse steel bars 4 are stuck in the transverse steel bar positioning grooves 12 to maintain the position between the two transverse steel bars 4 and will not be offset during the pouring and vibration process.

[0049] A vertical steel bar positioning groove 11 is also provided on the component body 1. There are also two vertical steel bar positioning grooves 11, which are distributed on the sides of the two transverse steel bar positioning grooves 12 and are connected to the transverse steel bar positioning grooves 12. The vertical steel bars 3 tied with the transverse steel bars 4 can be inserted into the vertical steel bar positioning grooves 11 for positioning. At the same time, since the transverse steel bar positioning grooves 12 and the vertical steel bar positioning grooves 11 are connected, the steel wire used to tie the transverse steel bars 4 and the vertical steel bars 3 can fall between the transverse steel bar positioning grooves 12 and the vertical steel bar positioning grooves 11.

[0050] Furthermore, in order to prevent the vertical steel bars 3 from being separated from the vertical steel bar positioning grooves 11 during the concrete pouring and vibration process. In the present application, the two vertical steel bar positioning grooves 11 are distributed on both sides of the width direction of the component body 1, and the bottoms of the two vertical steel bar positioning grooves 11 are on the same straight line in the length direction of the component body 1. In this way, when the two vertical steel bars 3 are inserted into the corresponding two vertical steel bar positioning grooves 11, since the directions in which the two vertical steel bars 3 are separated from the vertical steel bar positioning grooves 11 are opposite, the vertical steel bars 3 will not be easily separated from the vertical steel bar positioning grooves 11 during the concrete pouring and vibration process.

[0051] Reference Figure 3-5 In addition, since the opening directions of the two vertical steel bar positioning grooves 11 are opposite, in order to facilitate the two vertical steel bars 3 to be respectively inserted into the two vertical steel bar positioning grooves 11, the two vertical steel bar positioning grooves 11 in this application are both set as arc grooves, and the arc path is formed with the center of the bottom of the other vertical steel bar positioning groove 11 as the center of the circle and the distance between the two vertical steel bars 3 as the radius.

[0052] A connecting groove 13 is provided along the length of the component body 1, connecting the two vertical reinforcement positioning grooves 11. The connecting groove is located on the side facing away from the transverse reinforcement positioning groove 12. During concrete pouring, concrete can flow into the connecting groove 13, allowing the concrete to better wrap around the vertical reinforcement 3 and transverse reinforcement 4, preventing the component body 1 from blocking the flow of concrete and thus affecting the stability of the connection between the vertical reinforcement 3 and transverse reinforcement 4.

[0053] At the same time, in order to improve the structural strength of the component body 1 itself, two reinforcing steel bars 14 are pre-embedded inside the component body 1. The length directions of the two reinforcing steel bars 14 are consistent with the length direction of the component body 1, and the two reinforcing steel bars 14 are respectively arranged on the sides of the two vertical steel bar positioning grooves 11.

[0054] The implementation principle of a concrete support member in the embodiment of the present application is:

[0055] When installing the component body 1, it is necessary to first place the component body 1 obliquely between the two vertical steel bars 3, and then control the movement of the component body 1 so that one vertical steel bar 3 falls into the vertical steel bar positioning groove 11 first. After the vertical steel bar 3 enters the corresponding vertical steel bar positioning groove 11, rotate the component body 1 toward the other vertical steel bar 3, and the other vertical steel bar 3 can enter the vertical steel bar positioning groove 11 along the arc trajectory of the other vertical steel bar positioning groove 11 to complete the alignment. At this time, the length direction of the component body 1 is consistent with the direction of the connection line of the two vertical steel bars 3. Then move the component body 1 downward again so that the transverse steel bar positioning groove 12 on the component body 1 can be placed on the corresponding transverse steel bar 4, thereby completing the installation of the component body 1.

[0056] Example 2

[0057] Reference Figure 6 and Figure 7 The present embodiment provides a mold for manufacturing a concrete support member, which is used to manufacture the concrete support member of Example 1. The mold includes a bottom plate 25, a first side plate 21 and a second side plate 22 opposite each other, and two positioning blocks 23. The bottom plate 25, the first side plate 21, the second side plate 22, and the two positioning blocks 23 can enclose a forming area 28 for forming the support member.

[0058] Furthermore, a vertical tenon 26 and a transverse tenon 27 are provided on each of the first side plate 21 and the second side plate 22. The vertical tenon 26 and the transverse tenon 27 are abutted against each other and are used to form the vertical steel bar positioning groove 11 and the transverse steel bar positioning groove 12 respectively.

[0059] The bottom plate 25 is provided with a convex strip 251 for forming the connecting groove 13, and the convex strip 251 is provided with an avoidance groove 252 for positioning the two vertical tenons 26. The avoidance groove 252 is an arc-shaped structure, so when the two vertical tenons 26 are respectively stuck in the corresponding avoidance groove 252, the positions of the first side plate 21 and the second side plate 22 can be positioned.

[0060] Vertical positioning grooves 231 are provided on both sides of the positioning block 23, and positioning protrusions 211 are provided at both ends of the first side plate 21 and the second side plate 22. The positioning protrusions 211 can be inserted into the positioning grooves 231 to position the positioning block 23, thereby preventing the positioning block 23 from being offset during use.

[0061] The manufacturing mold also includes two positioning scrapers 24, which have an inverted U-shaped structure and include two limiting rod portions 241 located on both sides and a scraper portion 242 located above. When the first side plate 21 and the second side plate 22 are positioned on the bottom plate 25, the two limiting rod portions 241 are located on the outside of the first side plate 21 and the second side plate 22 to limit the separation of the first side plate 21 and the second side plate 22. At the same time, the two limiting rod portions 241 are also located on the outside of the positioning block 23, which can improve the stability of the positioning block 23 during use.

[0062] In addition, it should be noted that the first side panel 21, the second side panel 22, the positioning block 23, the bottom plate 25 and the positioning scraper 24 in the present application are all made of wood, and the surface is coated with anti-stick paint to prevent concrete from sticking, which can facilitate the subsequent demoulding of the finished product.

At this time, the bottom panel 25, the first side panel 21, the second side panel 22 and the two positioning blocks 23 can enclose and form a forming interval 28 due to the forming support component.

[0066] S2. Place the positioning scraper 24 on the first side plate 21 and the second side plate 22. The scraper portion 242 of the positioning scraper 24 is located on the upper end surfaces of the first side plate 21 and the second side plate 22. The two limiting rods 241 of the positioning scraper 24 are located on the outside of the first side plate 21 and the second side plate 22, and on both sides of the positioning blocks 23, thereby further positioning the first side plate 21, the second side plate 22, and the two positioning blocks 23.

[0067] S3 . Pour concrete into the forming section 28 , ensuring that the poured amount of concrete exceeds the volume of the forming section 28 so that the concrete can overflow out of the forming section 28 .

[0068] S4, vibrate the concrete, then move the positioning scraper 24 horizontally to level the concrete on the upper end surface of the forming section 28;

[0069] S5. After the concrete solidifies for a period of time, the mold is removed to demould the supporting components.

[0070] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application.
