Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a spacer assembly and installation method for beam reinforcement. Background Technology

[0002] A reinforced concrete beam is a beam made of reinforced concrete. Reinforced concrete beams can be constructed as independent beams, integrated with reinforced concrete slabs to form beam-slab floor systems, or integrated with reinforced concrete columns to form single-story or multi-story frames. Reinforced concrete beams come in a variety of forms and are the most basic load-bearing components in building construction, bridge construction, and other engineering structures, with extremely wide applications.

[0003] After the reinforcing bars of beams and columns are tied, spacers are often used to isolate the bottom and side bars of the beam when placing them in the concrete pouring trench of the formwork. This ensures that there is a gap between the beam and the formwork, preventing exposed bars and insufficient protective layer. However, the existing spacers have poor adaptability in terms of width adjustment according to the set spacing. At the same time, the use of traditional spacers makes it easy for workers to walk on the tied reinforcing bars in the formwork, and for the beam to vibrate and detach or shift from the spacers when vibrating equipment is used during concrete pouring. As a result, after the concrete is poured, exposed bottom bars and insufficient protective layer on the sides of the beam are likely to occur. Summary of the Invention

[0004] To address the aforementioned deficiencies in existing technologies, a spacer assembly and installation method for beam reinforcement are provided, which effectively protects the beam reinforcement and formwork, preventing exposed reinforcement during construction.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0006] A spacer assembly for beam reinforcement, characterized in that: a plurality of spacer assemblies are spaced apart along the length of the beam reinforcement; the spacer assembly includes

[0007] Bottom reinforcement spacers and protective layer spacers: several bottom reinforcement spacers are located between the beam reinforcement and the bottom of the formwork, and two protective layer spacers are located between the two sides of the beam reinforcement and the side of the formwork, respectively. The bottom reinforcement spacers and protective layer spacers are located on the same cross section of the beam reinforcement.

[0008] The anti-leakage reinforcement structure is set on the bottom reinforcement pad. The top of the anti-leakage reinforcement structure is provided with a bottom reinforcement placement seat for placing the beam reinforcement. The height of the bottom reinforcement placement seat is adjustable. The distance between the bottom reinforcement placement seat and the bottom surface of the bottom reinforcement pad is adjusted according to the distance between the beam reinforcement and the bottom of the formwork.

[0009] The protective layer adjustment mechanism is located on the protective layer pad and is positioned close to the beam reinforcement. The protective layer adjustment mechanism has a horizontal adjustment function, which adjusts the horizontal dimension of the protective layer adjustment mechanism according to the distance between the beam reinforcement and the side of the formwork.

[0010] According to the above technical solution, at least three bottom reinforcement pads are included, two of which are located directly below the leftmost and rightmost bottom reinforcement bars of the beam, and the remaining bottom reinforcement pads are arranged at intervals between the leftmost and rightmost bottom reinforcement pads.

[0011] According to the above technical solution, it also includes a telescopic rod and an adjusting and protective component. The telescopic rod is set between two adjacent bottom reinforcement pads, and the length of the telescopic rod is adjusted according to the width of the beam reinforcement. The adjusting and protective component is located on the outside of the leftmost and rightmost bottom reinforcement pads, and rollers are provided on the outside of the adjusting and protective component. According to the gap between the outside of the bottom reinforcement pad and the side of the formwork, it is ensured that the adjusting and protective component and the side of the formwork are always in rolling contact.

[0012] According to the above technical solution, the telescopic rod includes an outer sleeve and an inner rod, which are slidably connected. The ends of the outer sleeve and the inner rod that are far apart from each other are respectively fixedly connected to two adjacent bottom rib pads. The top of the outer sleeve is open.

[0013] The adjustment and protection assembly includes a moving rod, a moving pad, and an adjusting screw. A horizontal groove along the width of the beam reinforcement is provided inside the bottom reinforcement bar. The end of the horizontal groove near the side of the formwork passes through the bottom reinforcement pad, and the end away from the side of the formwork has a threaded hole. The moving rod is placed inside the horizontal groove and passes through the outer side of the leftmost or rightmost bottom reinforcement pad. The moving pad is fixed to the end of the moving rod located on the outer side of the bottom reinforcement pad. A roller is located on the side of the moving rod near the side of the formwork. The adjusting screw passes through the threaded hole and is connected to the end of the moving rod via a bearing in a rotatable manner. An adjusting scale is fixed to the surface of the moving rod extending beyond the bottom reinforcement pad.

[0014] According to the above technical solution, it also includes a movable buffer component, which is located between the adjusting anti-leakage reinforcement structure and the bottom reinforcement pad. The movable buffer component includes a buffer state and a locking state. When the beam reinforcement is placed on the adjusting anti-leakage reinforcement structure, the movable buffer component changes from the buffer state to the locking state. In the locking state, the height of the movable buffer component is constant.

[0015] According to the above technical solution, the movable buffer assembly includes a buffer structure, a buffer seat, and a locking structure. The bottom rib pad has segmented slots, which are divided into an embedding slot at the top of the bottom rib pad, a placement slot at the top of the bottom rib pad communicating with the embedding slot, and an installation cylinder embedded inside the bottom rib pad communicating with the placement slot. The buffer structure is located inside the installation cylinder, with its bottom fixed to the bottom of the installation cylinder, and its top fixedly connected to the bottom of the buffer seat. The locking structure is located on the side of the buffer seat, and a locking groove matching the locking structure is provided on the side of the placement slot. As the locking structure moves downwards with the buffer structure, it engages with the locking groove.

[0016] According to the above technical solution, the buffer structure includes a buffer spring, a resistance ring, and a movable base. The resistance ring and the mounting cylinder are arranged coaxially, and the outer diameter of the resistance ring is the same as the inner diameter of the mounting cylinder. The size of the movable base matches the inner diameter of the resistance ring. The two ends of the buffer spring are respectively fixed between the bottom surfaces of the movable base and the mounting cylinder. The top surface of the movable base is fixedly connected to the buffer base.

[0017] The locking structure includes a locking spring and a locking plug. Coaxial mounting holes are provided on both sides of the buffer seat. The locking plug includes a wedge-shaped plug end and a straight rod end. The straight rod end is placed inside the mounting hole. The locking spring is fitted onto the straight rod of the locking plug, and both ends of the locking spring are connected to the locking plug and the inner wall of the mounting hole, respectively. When the spring is extended, the distance between the locking plugs in the mounting holes on both sides is greater than the width of the placement groove. When the spring is compressed, the distance between the locking plugs in the mounting holes on both sides is less than the width of the placement groove.

[0018] According to the above technical solution, the adjustable anti-leakage rib structure includes a threaded rod, a threaded adjustment frame, and a bottom rib scale. The threaded rod is vertically arranged, and its bottom end is fixed to the top of the buffer seat. The top end of the threaded rod is connected to the threaded adjustment frame by a threaded connection. The bottom rib placement seat is located on the top of the threaded adjustment frame by a rotatable connection. A vertical measuring hole is provided on the bottom rib pad, and the bottom rib scale is vertically arranged in the measuring hole. The bottom rib scale is fixedly connected to the bottom rib placement seat, and the height difference between the bottom surface of the bottom rib placement seat and the bottom rib pad is displayed in real time through the bottom rib scale.

[0019] According to the above technical solution, the protective layer adjustment mechanism includes a positioning moving rod, a moving adjusting block, a return spring, a positioning rack, and a positioning scale. A horizontal cavity and a vertical hollow cylinder are provided on the protective layer pad. The vertical hollow cylinder is positioned above and connected to the horizontal cavity. The positioning moving rod is horizontally slidably connected within the horizontal cavity, and the end of the positioning rod near the beam reinforcement penetrates the protective layer pad, with the penetrating end of the positioning rod fixedly connected to the moving adjusting block. The positioning rack is located within the vertical hollow cylinder, and a pull rod is provided at its top. The ring has a return spring connecting plate in the middle and a rack end at the bottom, which passes through the vertical hollow cylinder. The return spring is sleeved on the positioning rack in a stretched state. The top of the return spring is fixed to the return spring connecting plate, and the bottom of the return spring is fixed to the bottom of the vertical hollow cylinder. Several toothed grooves matching the rack end are provided at intervals on the positioning moving rod. Under the action of the return spring, the rack end of the positioning rack is inserted into one of the toothed grooves. A positioning scale is provided on the positioning moving rod to measure the horizontal distance between the moving adjustment block and the side of the beam reinforcement and the side of the formwork.

[0020] A method for installing reinforcing bars in beams, characterized by comprising the following steps:

[0021] S1: After the formwork is erected and the beam reinforcement is tied, determine and record the required isolation distances between the beam reinforcement and the bottom of the formwork, and between the beam reinforcement and the side of the formwork, according to the construction requirements.

[0022] S2: Based on the data recorded in S1, adjust the anti-leakage reinforcement structure and the size of the protective components;

[0023] S3: Arrange multiple sets of pad block components at equal intervals according to the length of the tied beam reinforcement. Attach the bottom reinforcement pads to the pre-set bottom reinforcement of the tied beam. Then place the tied beam reinforcement and the bottom reinforcement pads together in the beam pouring groove where the formwork is laid.

[0024] S4: Arrange multiple sets of protective layer spacers at equal intervals according to the length of the tied beam reinforcement. Place the protective layer spacers on the right angles of the formwork on both sides of the beam pouring groove, and adjust the horizontal dimension of the protective layer adjustment mechanism according to the spacing between the beam reinforcement and the side of the formwork.

[0025] The present invention has the following beneficial effects:

[0026] 1. By setting bottom reinforcement spacers and protective layer spacers, and setting height-adjustable anti-reinforcement structures and horizontal dimension-adjustable protective layer adjustment mechanisms on the bottom reinforcement spacers and protective layer spacers respectively; several spacer components are arranged at intervals along the length of the beam reinforcement to ensure that the distance between the sides and bottom of the beam reinforcement and the sides and bottom of the formwork is kept within the design range; when the beam reinforcement is tied and placed in the concrete pouring trench of the formwork, the spacer components effectively isolate the beam reinforcement from the erected formwork, effectively protecting the beam reinforcement and the formwork and avoiding exposed reinforcement during construction.

[0027] 2. Several bottom reinforcement blocks of the pad assembly are connected by telescopic rods, and adjustment and protection components are set on the sides of the leftmost and rightmost bottom reinforcement blocks. The bottom reinforcement blocks are connected into a whole by the telescopic rods and adjustment and protection components. Since the lateral dimensions of the telescopic rods and adjustment and protection components are adjustable, the pad assembly can be matched with beam reinforcement formwork of various widths, which greatly improves the applicability of the pad assembly.

[0028] 3. A buffer structure is set up to reduce the impact force of the beam reinforcement moving downward, so as to avoid the bottom reinforcement pad block breaking and being damaged; at the same time, a locking structure is set up to fix the final height of the moving buffer component, thereby ensuring that the height difference between the bottom reinforcement placement seat at the top of the adjustable anti-leakage reinforcement structure and the bottom of the bottom reinforcement pad block is fixed.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] Reference Figures 1-3 As shown, this invention provides a spacer assembly for beam reinforcement, with several spacer assemblies spaced at intervals along the length of the beam reinforcement. Each spacer assembly includes bottom reinforcement spacers 1 and protective layer spacers 2. The bottom reinforcement spacers are located between the beam reinforcement and the bottom of the formwork, while two protective layer spacers are located between the two sides of the beam reinforcement and the side of the formwork, respectively. The bottom reinforcement spacers and protective layer spacers are located on the same cross-section of the beam reinforcement. An adjustable anti-leakage reinforcement structure 3 is provided on the bottom reinforcement spacers. The top of the adjustable anti-leakage reinforcement structure has a bottom reinforcement placement seat 3-1 for placing the beam reinforcement. The height of the bottom reinforcement placement seat is adjustable, adjusting the distance between the bottom reinforcement placement seat and the bottom surface of the bottom reinforcement spacers according to the distance between the beam reinforcement and the bottom of the formwork. A protective layer adjustment mechanism 4 is provided on the protective layer spacers, positioned close to the beam reinforcement. The protective layer adjustment mechanism has a horizontal dimension adjustment function, adjusting the horizontal dimension according to the distance between the beam reinforcement and the side of the formwork.

[0035] This embodiment sets up bottom reinforcement spacers and protective layer spacers, and respectively sets up height-adjustable anti-leakage reinforcement structures and protective layer adjustment mechanisms on the bottom reinforcement spacers and protective layer spacers; several spacer assemblies are arranged at intervals along the length of the beam reinforcement to ensure that the distance between the sides and bottom of the beam reinforcement and the sides and bottom of the formwork is kept within the design range; when the beam reinforcement is tied and placed in the concrete pouring trench of the formwork, the spacer assemblies form an effective isolation between the beam reinforcement and the erected formwork, effectively protecting the beam reinforcement and the formwork and avoiding the phenomenon of exposed reinforcement during the construction process.

[0036] Furthermore, it includes at least three bottom reinforcement pads, two of which are located directly below the leftmost and rightmost bottom reinforcement bars of the beam, and the remaining bottom reinforcement pads are spaced apart between the leftmost and rightmost bottom reinforcement pads (in the embodiment shown in the figure, three bottom reinforcement pads are selected, and the third bottom reinforcement pad is located directly below the bottom reinforcement bar near the midpoint between the leftmost and rightmost bottom reinforcement pads).

[0037] In some of the above embodiments, a telescopic rod 5 and an adjusting and protective component 6 are also included. The telescopic rod is set between two adjacent bottom reinforcement pads, and the length of the telescopic rod is adjusted according to the width of the beam reinforcement. The adjusting and protective component is located on the outer side of the leftmost and rightmost bottom reinforcement pads, and rollers 6-4 are provided on the outer side of the adjusting and protective component. According to the gap between the outer side of the bottom reinforcement pad and the side of the template, the adjusting and protective component and the side of the template are always in rolling contact.

[0038] In this embodiment, several bottom reinforcement blocks of the pad assembly are connected by telescopic rods, and adjustment and protection components are provided on the sides of the leftmost and rightmost bottom reinforcement blocks. The bottom reinforcement blocks are connected into a whole by the telescopic rods and adjustment and protection components. Since the lateral dimensions of the telescopic rods and adjustment and protection components are adjustable, the pad assembly can be matched with beam reinforcement formwork of various widths, which greatly improves the applicability of the pad assembly.

[0039] Furthermore, the telescopic rod includes an outer sleeve 5-1 and an inner rod 5-2, which are slidably connected. The ends of the outer sleeve and the inner rod that are far apart from each other are fixedly connected to two adjacent bottom reinforcement pads. The top of the outer sleeve is open, which is used to inject concrete into the outer sleeve during concrete pouring to ensure an integral molding effect.

[0040] The adjustment and protection assembly includes a moving rod 6-1, a moving pad 6-2, and an adjusting screw 6-3. A horizontal groove 1-1 along the width of the beam reinforcement is provided inside the bottom reinforcement. The end of the horizontal groove near the side of the formwork passes through the bottom reinforcement pad, and the end of the horizontal groove away from the side of the formwork has a threaded hole (or, as in this embodiment, a threaded cylinder that is threadedly connected to the adjusting screw can be embedded and fixed inside the bottom reinforcement pad). The moving rod is placed inside the horizontal groove and passes through the outer side of the leftmost or rightmost bottom reinforcement pad along with the horizontal groove. The moving pad is fixed to the end of the moving rod located on the outer side of the bottom reinforcement pad, and a roller is provided on the side of the moving rod near the side of the formwork. The adjusting screw passes through the threaded hole and is connected to the end of the moving rod via a bearing in a rotatable manner. An adjusting scale is fixed to the surface of the moving rod extending out of the bottom reinforcement pad.

[0041] In the embodiment shown in the figure, the moving rod and the moving pad are both made of concrete, while the adjusting screw and the adjusting scale are both made of stainless steel. A stainless steel embedded shaft seat is movably installed at the connection between the adjusting screw and the moving rod, and is embedded and fixed inside the moving rod.

[0042] In this embodiment, the length of the adjusting screw extending into the horizontal groove is controlled by rotating the adjusting screw. Since only circular rotation occurs between the adjusting screw and the moving rod, the length of the moving rod extending beyond the bottom reinforcement pad near the side of the formwork also changes when the length of the adjusting screw extending into the horizontal groove changes. The adjustment scale on the surface of the moving rod can read the horizontal distance between the roller and the side of the bottom reinforcement pad. Therefore, the operator can use the adjusting screw and the adjustment scale to ensure that the horizontal distance between the roller and the side of the bottom reinforcement pad meets the design requirements for the distance between the beam reinforcement and the side of the formwork.

[0043] In some of the above embodiments, a movable buffer assembly 7 is also included. The movable buffer assembly is disposed between the adjusting anti-leakage reinforcement structure and the bottom reinforcement pad. The movable buffer assembly includes a buffer state and a locking state. When the beam reinforcement is placed on the adjusting anti-leakage reinforcement structure, the movable buffer assembly changes from the buffer state to the locking state. In the locking state, the height of the movable buffer assembly is constant. This embodiment utilizes the movable buffer assembly to reduce the impact force of the beam reinforcement moving downward, avoiding damage to the bottom reinforcement pad.

[0044] Specifically, the movable buffer assembly includes a buffer structure 7-1, a buffer seat 7-2, and a locking structure 7-3. The bottom rib pad has segmented slots, which are divided into an embedding slot 1-21 on the top of the bottom rib pad, a placement slot 1-22 on the top of the bottom rib pad communicating with the embedding slot, and an installation cylinder 1-23 embedded inside the bottom rib pad communicating with the placement slot. The buffer structure is located inside the installation cylinder, with its bottom fixed to the bottom of the installation cylinder, and its top fixedly connected to the bottom of the buffer seat. The locking structure is located on the side of the buffer seat, and a locking groove 1-3 matching the locking structure is provided on the side of the placement slot. As the locking structure moves downwards with the buffer structure, it engages with the locking groove.

[0045] A buffer structure is installed to reduce the impact force of the beam reinforcement moving downwards, thus preventing the bottom reinforcement pad from breaking and being damaged. At the same time, a locking structure is installed to fix the final height of the moving buffer assembly, thereby ensuring that the height difference between the bottom reinforcement placement seat located at the top of the adjustable anti-leakage reinforcement structure and the bottom of the bottom reinforcement pad is fixed.

[0046] Furthermore, the buffer structure includes a buffer spring 7-11, a resistance ring 7-12, and a movable seat 7-13. The resistance ring and the mounting cylinder are arranged coaxially, and the outer diameter of the resistance ring is the same as the inner diameter of the mounting cylinder. The size of the movable seat matches the inner diameter of the resistance ring. The two ends of the buffer spring are respectively fixed between the bottom surfaces of the movable seat and the mounting cylinder. The top surface of the movable seat is fixedly connected to the buffer seat.

[0047] The locking structure includes a locking spring 7-31 and a locking plug 7-32. Coaxial mounting holes are provided on both sides of the buffer seat. The locking plug includes a wedge-shaped plug end and a straight rod end. The straight rod end is placed inside the mounting hole. The locking spring is fitted onto the straight rod of the locking plug, and both ends of the locking spring are connected to the locking plug and the inner wall of the mounting hole, respectively. When the spring is extended, the distance between the locking plugs in the mounting holes on both sides is greater than the width of the placement groove. When the spring is compressed, the distance between the locking plugs in the mounting holes on both sides is less than the width of the placement groove.

[0048] In this embodiment, the upper part of the buffer seat presses down on the movable seat, causing it to slowly move downwards against the elastic force of the buffer spring, thus preventing breakage or damage to the bottom rib pad. Additionally, a locking spring and a locking plug are provided, and a locking groove is used to restrict the upward movement of the locking plug, thereby fixing the final height of the buffer structure. This facilitates the calculation of the height between the bottom rib placement seat at the top of the anti-leakage rib structure and the bottom of the bottom rib pad.

[0049] Preferably, in order to facilitate the sliding of the locking plug in the mounting hole, a guide rod is provided in the mounting hole, and a matching guide groove is provided in the end of the locking plug located in the mounting hole; the guide hole and guide groove are used to restrict the movement direction of the locking plug in the mounting hole.

[0050] Preferably, to prevent the locking plug from sliding out of the locking groove and continuing to slide downwards, a limiting block and a limiting hole are respectively provided on the locking plug and in the groove, using the limiting block and the limiting hole to restrict the further downward sliding of the locking plug. Alternatively, a limiting protrusion is provided on the side wall of the placement groove, and after the locking plug is inserted into the locking groove, the limiting protrusion contacts the lower surface of the buffer seat, restricting the further downward movement of the buffer seat.

[0051] In the embodiment shown in the figure, the mounting cylinder, buffer spring, movable seat and buffer seat are all made of stainless steel, the resistance ring is made of brake pad material, and the resistance ring is provided with a resistance-increasing annular groove on the outside.

[0052] Specifically, the adjustable anti-leakage rib structure includes a threaded rod 3-2, a threaded adjustment bracket 3-3, and a bottom rib scale 3-4. The threaded rod is vertically arranged, and its bottom end is fixed to the top of the buffer seat. The top end of the threaded rod is connected to the threaded adjustment bracket via a threaded connection. The bottom rib placement seat is located on top of the threaded adjustment bracket via a rotatable connection. A vertical measuring hole is provided on the bottom rib pad, and the bottom rib scale is vertically arranged in the measuring hole. The bottom rib scale is fixedly connected to the bottom rib placement seat, and the height difference between the bottom surface of the bottom rib placement seat and the bottom rib pad is displayed in real time through the bottom rib scale.

[0053] Preferably, the bottom reinforcement placement seat and the threaded adjustment bracket rotate circumferentially. The top of the bottom reinforcement placement seat is provided with a semi-circular groove, and a magnet is fixedly installed in the semi-circular groove. The magnet ensures that the bottom reinforcement placement seat is attracted and fixed to the bottom reinforcement under the attraction of the magnet. By rotating the threaded adjustment bracket and referring to the bottom reinforcement scale, the height difference between the bottom surface of the bottom reinforcement placement seat and the bottom surface of the bottom reinforcement pad can be adjusted, thereby meeting the spacing requirements between the bottom surface of the beam reinforcement and the bottom surface of the formwork.

[0054] Furthermore, the protective layer adjustment mechanism includes a positioning moving rod 4-1, a moving adjusting block 4-2, a return spring 4-3, a positioning rack 4-4, and a positioning scale 4-5. A horizontal cavity 2-1 and a vertical hollow cylinder 2-2 are provided on the protective layer pad. The vertical hollow cylinder is positioned above and connected to the horizontal cavity. The positioning moving rod is horizontally slidably connected within the horizontal cavity, and the end of the positioning connecting rod near the beam reinforcement penetrates the protective layer pad, with the penetrating end of the positioning connecting rod fixedly connected to the moving adjusting block. The positioning rack is located within the vertical hollow cylinder. The top of the device has a pull ring, the middle has a return spring connecting plate, and the bottom has a rack end that passes through the vertical hollow cylinder. The return spring is sleeved on the positioning rack in a stretched state. The top of the return spring is fixed to the return spring connecting plate, and the bottom of the return spring is fixed to the bottom of the vertical hollow cylinder. Several toothed grooves 4-11 that match the rack end are provided at intervals on the positioning moving rod. Under the action of the return spring, the rack end of the positioning rack is inserted into one of the toothed grooves. A positioning scale is provided on the positioning moving rod to measure the horizontal distance between the moving adjustment block and the side of the beam reinforcement and the side of the formwork.

[0055] The vertical hollow cylinder, return spring, positioning rack, and positioning scale are all made of stainless steel, while the positioning moving rod and moving adjustment block are made of concrete. The positioning rack is separated from the positioning groove by the pull ring at the top of the positioning rack, thereby realizing the horizontal movement adjustment of the moving adjustment block.

[0056] Preferably, a first grouting hole 8 and a second grouting hole 9 are provided. The first grouting hole is vertically arranged inside the bottom reinforcement pad block and connects the external space and the horizontal groove of the bottom reinforcement pad block through the first grouting hole. The number of first grouting holes is at least two. The second grouting hole is vertically arranged inside the protective layer pad block and connects the external space and the horizontal cavity of the protective layer pad block through the first grouting hole. The number of second grouting holes is at least two. The provision of the first and second grouting holes facilitates the entry of concrete into the component during concrete pouring, allowing it to solidify together and improving the overall strength.

[0057] Specifically, the adjustment scale, the bottom rib scale, and the positioning scale are all equipped with graduations. The graduations on the adjustment scale gradually increase from the outer end of the bottom rib pad to the inner end. The starting graduation on the bottom rib scale is the length of the straight-line distance between the outer edge of the roller and the moving pad, and it gradually increases. When the moving adjustment block contacts the protective layer pad, the two ends of the positioning scale are aligned with the outer edge of the moving adjustment block and the inner edge of the protective layer pad, respectively.

[0058] The present invention also provides a method for installing reinforcing bars in beams, characterized by comprising the following steps:

[0059] S1: After the formwork is erected and the beam reinforcement is tied, determine and record the required isolation distances between the beam reinforcement and the bottom of the formwork, and between the beam reinforcement and the side of the formwork, according to the construction requirements.

[0060] S2: Based on the data recorded in S1, adjust the anti-leakage reinforcement structure and the size of the protective components;

[0061] Specifically as follows:

[0062] First, based on the two sets of data recorded regarding the required isolation distance between the reinforcing bars and the bottom of the formwork, rotate the threaded adjustment bracket while referring to the data on the bottom reinforcement scale. Make the distance between the bottom wall of the adjusted bottom reinforcement placement seat's groove and the bottom surface of the bottom reinforcement pad equal to the recorded isolation distance between the bottom reinforcement of the beam and the bottom of the formwork. (It should be noted that the height of the bottom reinforcement pad is a fixed value, and the downward movement distance of the buffer seat is a fixed value. Therefore, the distance between the bottom wall of the bottom reinforcement placement seat's groove and the bottom reinforcement pad is determined as the top display scale of the scale plus the height value of the bottom reinforcement pad minus the fixed downward movement value of the buffer seat.)

[0063] Secondly, by rotating the adjusting screw according to the recorded data between the beam reinforcement and the side of the formwork and referring to the adjusting scale, the adjusting pad can be moved to the control distance (it should be noted that the bottom reinforcement placement seat is located in the middle of the bottom reinforcement pad, so the determined value is the maximum value displayed by the adjusting scale plus half the horizontal width distance of the bottom reinforcement pad), thus completing the effective adjustment of the three bottom reinforcement pads.

[0064] Finally, adjust the scale on the reference positioning ruler of the threaded adjustment bracket according to the recorded data between the beam reinforcement and the side of the formwork to achieve the recorded value.

[0065] S3: Arrange multiple sets of pad block components at equal intervals according to the length of the tied beam reinforcement. Attach the bottom reinforcement pads to the pre-set bottom reinforcement of the tied beam. Then place the tied beam reinforcement and the bottom reinforcement pads together in the beam pouring groove where the formwork is laid.

[0066] Taking the embodiment shown in the figure as an example, multiple sets of bottom reinforcement pads and protective layer pads are carried. The bottom reinforcement pads are arranged in groups of three, and the protective layer pads are arranged in groups of two. Then, the three bottom reinforcement placement seats on the three bottom reinforcement pads are respectively attached to the left and right main reinforcement bars and the middle main reinforcement bar of the bottom reinforcement of the tied beam. They are set one by one, and multiple sets of bottom reinforcement pads are arranged at equal intervals according to the length of the tied beam reinforcement. After placement, the tied beam reinforcement is placed in the beam pouring groove where the formwork is laid, and the roller rolls down along the formwork wall.

[0067] It should be noted that during the process of lowering the reinforcing bars of the tied beam, when the bottom reinforcement pad comes into contact with the bottom formwork, the bottom reinforcement placement seat is pressed down as a whole. This causes the buffer seat to move down, which in turn moves the moving seat down. At the same time, the buffer spring is compressed and friction increases with the friction ring, which reduces the impact force of the downward movement and avoids the bottom reinforcement pad breaking or being damaged. Meanwhile, when the buffer seat moves into the placement groove, the spring elastically resets and inserts into the positioning groove to complete the locking and fixing.
