Description
Technical Field
[0001] This application relates to the field of building construction, and in particular to a mold for positioning steel bars in pier columns. Background Technology
[0002] Currently, pre-embedded steel foundations are a common type of foundation construction method. During construction, steel bars are pre-embedded in concrete to improve the strength and stability of the foundation.
[0003] In the current practice, when pouring concrete for the reinforcement of pier columns, the position of the reserved protective layer is usually first measured and marked on the pier cap before the reinforcement is embedded. Then, after the concrete is poured on the pier cap, the position of the protective layer is marked again.
[0004] The existing technical solutions mentioned above have the following defects: when concrete is poured for the foundation reinforcement, the foundation reinforcement and the embedded reinforcement of the pre-pier column are easily disturbed, resulting in deviations in the overall dimensions of the pre-embedded pier column. Utility Model Content
[0005] In order to achieve the effect of limiting the position of the pre-embedded pier reinforcement bars when pouring concrete for the pier reinforcement bars, this application provides a mold for positioning pier reinforcement bars.
[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:
[0007] It includes a limiting device installed on the pier, the pier and the limiting device are fixedly connected, the limiting device includes a limiting frame and a limiting ring, the limiting ring is fitted inside the limiting frame and fixedly connected to the limiting frame, the pier column reinforcement abuts against the inner side of the limiting ring, and the distance between the limiting frame and the limiting ring is the thickness of the protective layer of the pier column reinforcement.
[0008] By adopting the above scheme, a limiting device is fixedly connected to the pier cap. The limiting device includes a limiting frame and a limiting ring. The limiting frame is fixedly connected to the pier cap, and the limiting ring is placed inside the limiting frame and fixedly connected to the limiting frame. The distance between the limiting ring and the limiting frame is the thickness of the protective layer. After the limiting device is fixed to the pier cap, concrete is poured into the pier cap. After the concrete reaches the required performance, the limiting device is demolded. At this time, the limiting device leaves an imprint on the pier cap concrete. The protective layer mold is embedded into this imprint, which can accurately replicate the position of the protective layer mold. Through the above settings, the effect of limiting the embedded pier reinforcement is achieved when pouring concrete for the pier reinforcement.
[0009] Furthermore, a locking device is provided between the limiting frame and the support platform, which is used to fix the limiting frame and the support platform in place.
[0010] By adopting the above scheme, a locking device is set between the limiting frame and the foundation. Once the relative position of the limiting frame and the foundation is determined, the locking device is used to temporarily lock the position of the limiting frame and the foundation.
[0011] Furthermore, the limiting frame includes U-shaped rods and straight rods. The U-shaped rods are symmetrically arranged, and there are at least two straight rods. Both ends of each straight rod are fixedly connected to one end of the two U-shaped rods in the horizontal direction.
[0012] By adopting the above scheme, the limiting frame is divided into U-shaped rods and straight rods. The U-shaped rods are arranged symmetrically, and the straight rods are arranged symmetrically. The two ends of each straight rod are fixedly connected to the U-shaped rods, so that the entire limiting frame can be detachably connected.
[0013] Furthermore, both the U-shaped rod and the straight rod include an upper end plate, a lower end plate, and a connecting plate. The two ends of the connecting plate are fixedly connected to the upper end plate and the lower end plate, respectively, so that both the U-shaped rod and the straight rod form a groove.
[0014] Furthermore, a fixing plate is fixedly connected to both ends of the groove of each U-shaped rod and straight rod, and the fixing plates of the U-shaped rod and straight rod abut against each other when the U-shaped rod and straight rod are spliced.
[0015] By adopting the above scheme, the U-shaped rod and the straight rod are configured to consist of an upper end plate, a lower end plate, and a connecting plate. The two ends of the connecting plate are fixedly connected to the upper end plate and the lower end plate, respectively. This configuration creates a groove on both the U-shaped rod and the straight rod. Then, a fixing plate is fixedly connected to both ends of each groove. When the U-shaped rod and the straight rod are spliced, the fixing plates of the U-shaped rod and the straight rod abut against each other, thereby connecting the adjacent fixing plates to complete the assembly of the limiting frame.
[0016] Furthermore, several reinforcing plates are provided between each adjacent fixed plate, with the two ends of the reinforcing plates being fixedly connected to the upper end plate and the lower end plate, respectively. The reinforcing plates are used to increase the strength of the U-shaped rod and the straight rod.
[0017] By adopting the above scheme, in order to increase the strength of the U-shaped rod, several reinforcing plates are fixedly connected between each adjacent fixed plate.
[0018] Furthermore, the limiting device also includes a limiting ring and support rods. Each U-shaped rod and straight rod is provided with a corresponding limiting ring. Several support rods are provided between the U-shaped rod and the limiting ring, and between the straight rod and the limiting ring. The two ends of the several support rods are fixedly connected to the limiting ring and the U-shaped rod, and the limiting ring and the straight rod, respectively.
[0019] By adopting the above scheme, a limiting ring is set on the inner wall of each U-shaped rod and straight rod. The limiting ring is connected to the U-shaped rod or the straight rod by a support rod. The inner wall of the limiting ring is used to limit the position of the pier column reinforcement. The length of the support rod is the thickness of the protective layer of the pier column reinforcement, thereby accurately limiting the thickness of the protective layer of the pier column reinforcement.
[0020] Furthermore, the locking device includes a locking plate and a push rod. One end of the locking plate is fixedly connected to the limiting frame. A locking block is slidably connected to the side of the locking plate near the support and the end near the limiting frame. Several slots are provided on the locking plate, and set screws are inserted into the slots. When the locking block abuts against the template at the edge of the support, the set screws are used to limit and lock the position of the locking block. A push plate is fixedly connected to the end of the locking plate away from the locking block. The push plate is correspondingly set to the locking block. The push rod is threadedly connected to the push plate. After the relative position of the limiting frame and the support is determined, the side wall of the support is engaged between the locking block and the push plate. At this time, the push rod is rotated until the push rod abuts against the side wall of the template at the edge of the support.
[0021] By adopting the above scheme, a locking plate is fixedly connected to the limiting frame. A locking block is slidably connected to the side of the locking plate near the support and the end near the limiting frame. A push plate is fixedly connected to the end of the locking plate away from the locking block. With the above settings, there is a gap between the locking block and the push plate. The gap between the locking block and the push plate is used to engage the side wall of the support. Then, a slot is threadedly connected to the push plate. After the positional relationship between the support and the limiting frame is determined, the slot is rotated until it abuts against the side wall of the support, thereby locking the positional relationship between the limiting frame and the support.
[0022] Furthermore, there are two limit frames, and a crossbar is provided between the two limit frames. The two ends of the crossbar are fixedly connected to the two limit frames respectively.
[0023] In summary, this application has the following technical effects:
[0024] 1. By setting a limiting device, a limiting device is fixedly connected to the pier cap. The limiting device includes a limiting frame and a limiting ring. The limiting frame is fixedly connected to the pier cap, and the limiting ring is placed inside the limiting frame and fixedly connected to the limiting frame. The distance between the limiting ring and the limiting frame is the thickness of the protective layer. After the limiting device is fixed to the pier cap, concrete is poured into the pier cap. After the concrete reaches the required performance, the limiting device is demolded. At this time, the limiting device leaves an imprint on the pier cap concrete. The protective layer mold is embedded into this imprint, which can accurately replicate the position of the protective layer mold. Through the above settings, the pass rate of the pier column protective layer is improved.
[0025] 2. A locking device is installed, with a locking plate fixedly connected to the limiting frame. A locking block is slidably connected to the side of the locking plate closest to the bearing platform and the end closest to the limiting frame. A push plate is fixedly connected to the end of the locking plate furthest from the locking block. A gap exists between the locking block and the push plate, which is used to engage the side wall of the bearing platform. A slot 93 is then threaded onto the push plate. After the positional relationship between the bearing platform and the limiting frame is determined, the slot 93 is rotated until it abuts against the side wall of the bearing platform, thereby locking the positional relationship between the limiting frame and the bearing platform.
[0026] 3. By setting a limiting ring, a limiting ring is set on the inner wall of each U-shaped rod and straight rod. The limiting ring is connected to the U-shaped rod or the straight rod through a support rod. The inner wall of the limiting ring is used to limit the position of the pier column reinforcement. The length of the support rod is the thickness of the protective layer of the pier column reinforcement, thereby accurately limiting the thickness of the protective layer of the pier column reinforcement.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.
[0034] Reference Figure 1This embodiment provides a mold for positioning pier reinforcement bars, including a limiting device 3 set on a bearing platform 1. The bearing platform 1 is fixedly connected to the limiting device 3. In this embodiment, two pier reinforcement bars 2 are pre-embedded on the bearing platform 1. A limiting device 3 is sleeved on the outside of each pier reinforcement bar 2. A crossbar 6 is set between the two limiting devices 3. The two ends of the crossbar 6 are fixedly connected to the two limiting devices 3 respectively. A locking device 9 is set between each limiting device 3 and the template at the edge of the bearing platform 1. The locking device 9 is used to fix the limiting device 9 to the bearing platform 1.
[0035] Reference Figure 2 In this embodiment, there are two horizontal bars 6 between the two limiting devices 3. The two horizontal bars 6 are arranged in parallel, and the two ends of each horizontal bar 6 are fixedly connected to the two limiting frames 31, thereby fixing the two limiting devices 3 together. Several vertical bars 7 are also arranged between the two horizontal bars 6. The vertical bars 7 are all arranged perpendicular to the horizontal bars 6. In this embodiment, there are four vertical bars 7. The four vertical bars 7 are evenly distributed between the two horizontal bars 6. The two ends of each vertical bar 7 are fixedly connected to the two horizontal bars 6. Through the above arrangement, the two horizontal bars 6 are divided into five units. A stabilizing bar 8 is fixedly connected to each of the two adjacent units in the middle unit. The stabilizing bar 8 is used to enhance the stability of the connection of the horizontal bar 6.
[0036] Reference Figure 1 Each limiting device 3 includes a limiting frame 31 and a limiting ring 32. The limiting frame 31 and the limiting ring 32 are both sleeved on the outside of the pier column reinforcement 2. The limiting frame 31 is fixedly connected to the locking device 9. The inner diameter of the limiting frame 31 is the size of the pier column. The limiting ring 32 is set inside the limiting frame 31 and fixedly connected to the limiting frame 31. The limiting ring 32 abuts against the pier column reinforcement 2. The distance between the inner wall of the limiting frame 31 and the limiting ring 32 is the thickness of the protective layer of the pier column reinforcement 2.
[0037] Reference Figure 3 Each limiting frame 31 includes a U-shaped rod 311 and a straight rod 312. In this embodiment, each limiting frame 31 includes two U-shaped rods 311 and two straight rods 312. The two U-shaped rods 311 are symmetrically arranged, and the two straight rods 312 are symmetrically arranged. The two ends of each straight rod 312 are fixedly connected to the two U-shaped rods 311 respectively to form a complete limiting frame 31.
[0038] Reference Figure 3Each U-shaped rod 311 and straight rod 312 includes an upper end plate 3111, a lower end plate 3112, and a connecting plate 3113. The connecting plate 3113 is disposed between the upper end plate 3111 and the lower end plate 3112. The two ends of the connecting plate 3113 are fixedly connected to the upper end plate 3111 and the lower end plate 3112 respectively, so that a groove 34 is formed on the U-shaped rod 311 and the straight rod 312 by the interconnection of the upper end plate 3111, the lower end plate 3112, and the connecting plate 3113.
[0039] Reference Figure 3 Each groove 34 has a fixing plate 5 at both ends. The two ends of the fixing plate 5 are fixedly connected to the upper end plate 3111 and the lower end plate 3112, respectively. When the U-shaped rod 311 and the straight rod 312 abut against each other, the fixing plates 5 of the two grooves 34 abut against each other. At this time, a fastening bolt 50 is set between each pair of abutting fixing plates 5. The fastening bolt 50 passes through the two fixing plates 5 and is threadedly connected to the nut, thereby realizing the fixed connection between the two abutting fixing plates 5, and thus making the U-shaped rod 311 and the straight rod 312 fixedly connected, thereby completing the splicing of the limiting frame 31. Several reinforcing plates 4 are fixedly connected between the two fixing plates 5 in each groove 34. The two ends of the reinforcing plate 4 are fixedly connected to the upper end plate 3111 and the lower end plate 3112, respectively. The side wall of the reinforcing plate 4 is fixedly connected to the connecting plate 3113. The reinforcing plate 4 makes the limiting frame 31 more robust.
[0040] Reference Figure 3 Each U-shaped rod 311 and straight rod 312 is provided with a corresponding limiting ring 32. Several support rods 33 are provided between the limiting ring 32 and the straight rod 312. The two ends of each support rod 33 are fixedly connected to the limiting ring 32 and the straight rod 312 respectively. Several support rods 33 are also provided between the limiting ring 32 and the U-shaped rod 311. The two ends of each support rod 33 are fixedly connected to the limiting ring 32 and the U-shaped rod 311 respectively. When the U-shaped rod 311 and the straight rod 312 abut against each other, the limiting ring 32 abuts against each other at the same time. The pier column reinforcement 2 is set along the side of the limiting ring 32 away from the support rod 33. The pier column reinforcement 2 is fixedly connected to the foundation 1. The distance between the side of the limiting ring 32 away from the pier column reinforcement 2 and the limiting frame 31 is the thickness of the protective layer.
[0041] Reference Figure 4 and Figure 5Both sides of the limiting device 3 are provided with locking devices 9. Each locking device 9 includes a locking plate 94, a locking block 91 and a pushing plate 92. Each locking plate 94 is fixedly connected to the limiting frame 31. Each locking plate 94 is provided with a corresponding locking block 91. The locking block 91 is located on the locking plate 94 near the template of the support platform 1. The locking plate 94 is provided with a sliding groove 30. The locking block 91 is slidably connected to the sliding groove 30. The pushing plate 92 is provided with a corresponding locking block 91. The pushing plate 92 is fixedly connected to the end of the locking plate 94 away from the locking block. The gap between the pushing plate 92 and the locking block 91 is used to engage with the template at the edge of the support platform 1.
[0042] Reference Figure 4 and Figure 5 The locking plate 94 has several slots 93. A push rod 20 is internally threaded onto the push plate 92. When the template at the edge of the support 1 is engaged between the push plate 92 and the locking block 91, the locking block 91 is slid. Once the position of the locking block 91 is determined, a set screw 40 is provided in the slot 93. The set screw 40 is passed through the slot 93 to limit the locking block 91. Then, the push rod 20 is rotated so that it abuts against the template at the edge of the support 1. Through the combined action of the push rod 20 and the set screw 40, the locking of the limiting device 3 is completed. A number of pads 10 are fixedly connected to the foundation 1. The side of the pads 10 away from the foundation 1 abuts against the limiting device 3. When the limiting device 3 is fixedly connected to the foundation 1, the limiting device 3 is balanced as a whole. The limiting frame 31 is 3-5mm lower than the height of the foundation 1. This leaves a mark of the limiting frame 31 on the foundation 1 when concrete is poured. This mark is used to clamp the formwork of the protective layer of the pier reinforcement 2 into the mark when concrete is poured for the pier reinforcement 2, so as to avoid errors caused by the second measurement of the protective layer of the pier reinforcement 2.
[0043] The implementation principle of the mold for positioning the pier column reinforcement in this embodiment is as follows: When using this device to position the pier column reinforcement 2, firstly, each limiting frame 31 is spliced together, that is, the U-shaped rod 311 and the straight rod 312 are set to abut against each other. At this time, the fixing plates 5 are set to abut against each other in pairs. Then, the fastening bolts 50 are rotated in sequence. The fastening bolts 50 pass through the two fixing plates 5 and are threadedly connected to the nuts, thereby fixing the two abutting fixing plates 5 together, thereby fixing the U-shaped rod 311 and the straight rod 312 together, thus completing the splicing of the limiting frame 31. At this time, the limiting rings 32 are also set to abut against the pier column reinforcement 2. Then, the two ends of the two horizontal bars 6 are fixedly connected to the two limiting frames 31 respectively. Then, several point pads 10 are fixedly connected to the bearing platform 1. Then, the relative position of the limiting device 3 and the bearing platform 1 is determined, and the limiting device 3 is set to abut against the pier column reinforcement 2. Device 3 abuts against several pads 10, then slides locking block 91 until locking block 71 abuts against the edge of the foundation 1 mold, push screw 40 passes through slot 93 to limit locking block 91, then rotates push rod 20 to abut against foundation 1, and locks limiting device 3 through the combined action of push rod 20 and push screw 40; then set pier column steel bar 2 along the end away from support rod 33 along the hoop and fix pier column steel bar 2 to foundation 1, then pour concrete for foundation 1, and demold the device after the concrete is qualified. At this time, the position mark of limiting frame 31 is retained on foundation 1. This mark is used to clamp the template of the protective layer of pier column steel bar 2 into the mark when pouring concrete for pier column steel bar 2, so as to avoid errors in the second measurement of the protective layer of pier column steel bar 2.
