Description

Technical Field

[0001] This invention relates to the field of precast steel cage binding technology for prefabricated components, specifically to a grouting sleeve fixing tool for prefabricated column components. Background Art

[0002] Prefabricated buildings are characterized by being green, energy-saving, low-carbon, and environmentally friendly. They are also easy to modularize, industrialize, and commercialize. In recent years, they have been widely used in my country. When designing prefabricated components for prefabricated monolithic concrete structures, corresponding connection components need to be designed to ensure subsequent installation and fixing strength. When connecting prefabricated columns, sleeves and reserved steel bars are often used for connection and installation.

[0003] However, in the existing technology, the prefabrication of precast components in the factory is mainly constrained by the prefabrication of steel cages. For example, in the production of precast columns, manufacturers will allocate a large number of steelworkers to tie the steel bars. The traditional line drawing and tying method is prone to causing the sleeve steel bars to be misaligned. After the precast column steel cage is put into the mold, it does not match the mold. The sleeve steel bars need to be repositioned and tied, resulting in rework. At the same time, it affects the entire operation process, causing a large number of idle workers, low production efficiency, and increased costs. Summary of the Invention

[0004] The purpose of this invention is to provide a grouting sleeve fixing fixture for prefabricated column components, in order to solve the problem mentioned in the background art that the prefabrication of steel cages is a major limiting factor in the production efficiency of prefabricated components in the factory. For example, in the production of prefabricated columns, manufacturers will allocate a large number of steelworkers to perform steel bar binding operations. The traditional line-marking binding method is prone to causing the sleeve steel bar binding to be misaligned. After the prefabricated column steel cage is put into the mold, it does not match the mold, and the sleeve steel bar needs to be repositioned and bound, resulting in rework. At the same time, it affects the entire operation process, causing a large number of idle workers, low production efficiency, and increased costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a grouting sleeve fixing fixture for precast column components, comprising a bottom template, a side forming mold mounted on the upper part of the bottom template, a U-shaped groove provided on the surface of the side forming mold, and a side reinforcement mechanism mounted on the side of the side forming mold, the side reinforcement mechanism being used to reinforce the connection between the bottom template and the side forming mold, a limit adjustment mechanism being provided on the side of the U-shaped groove, the limit adjustment mechanism being fixedly connected to the outer wall of the side forming mold, the limit adjustment mechanism being used to limit and fix the sleeve and adjust the position of the sleeve.

[0006] In this invention, the bottom of the tied rebar cage is wound into the side forming mold, and the grouting connector protruding from the sleeve surface is placed inside the clamping plate. Then, the No. 3 clamping bolt is rotated to clamp and fix the grouting connector protruding from the sleeve surface, thereby fixing the sleeve. According to the specific position of the rebar in the rebar cage that needs to be connected to the sleeve, the slider is driven to slide along the slide rail by rotating the adjusting screw, thereby adjusting the position of the sleeve fixed inside the clamping plate. This allows the sleeve to be quickly connected and installed with the rebar, improving the efficiency of sleeve installation and the accuracy of sleeve installation position. Accurately adjusting the sleeve position ensures that the rebar in the precast column is precisely inserted into the sleeve, forming a stable connection between the rebar and the sleeve after grouting, effectively transferring stress, and ensuring the structural integrity of the precast column when bearing vertical and horizontal loads.

[0007] Preferably, a bottom reinforcement mechanism is installed on the upper part of the bottom template. The bottom reinforcement mechanism is used to reinforce the root of the side forming mold. The bottom reinforcement mechanism includes four No. 3 reinforcement plates. One end of the No. 3 reinforcement plate is fixedly connected to an insert block, and the other end of the No. 3 reinforcement plate is provided with a slot. The insert block and the slot are mutually adapted. The insert block at the end of one No. 3 reinforcement plate is inserted and fixed to the slot at the end of another No. 3 reinforcement plate. The insert block is T-shaped.

[0008] Preferably, the side reinforcement mechanism includes a base plate, the surface of which is provided with fixing bolts, the fixing bolts being threadedly connected to the surface of the bottom template, and the base plate and the bottom template being fixedly connected by the fixing bolts.

[0009] Preferably, a support plate is fixedly connected to the upper part of the base plate, and a reinforcing brace is fixedly connected at the connection between the base plate and the support plate.

[0010] Preferably, the surface of the support plate is threadedly connected to a No. 1 clamping bolt, the end of which is rotatably connected to a No. 1 reinforcing plate, and the surfaces of the No. 1 reinforcing plate and the No. 3 reinforcing plate are in contact.

[0011] Preferably, the support plate is threaded with a second clamping bolt, which is located above the first clamping bolt, and the end of the second clamping bolt is rotatably connected to a second reinforcing plate, which is in contact with the surface of the side forming mold.

[0012] Preferably, the limiting adjustment mechanism includes a slide rail, which is fixedly connected to the surface of the side forming mold, and a slider is slidably connected inside the slide rail. An adjusting screw is rotatably connected inside the slide rail, one end of which passes through the surface of the slide rail, and the adjusting screw is threadedly connected to the slider.

[0013] Preferably, the slider surface is fixedly connected to two connecting plates, which are symmetrically distributed on the slider surface. The connecting plates are threadedly connected to a No. 3 clamping bolt, and the end of the No. 3 clamping bolt is rotatably connected to a fixing block. The side of the fixing block is fixedly connected to a clamping plate.

[0014] Preferably, a fixing plate is fixedly connected to the surface of the fixing block, and a limiting rod is fixedly connected to the side of the fixing plate, the limiting rod being inserted into the connecting plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this invention, the bottom of the tied rebar cage is wound into the side forming mold. The grouting connector protruding from the sleeve surface is placed inside the clamping plate. Then, the No. 3 clamping bolt is rotated to clamp and fix the grouting connector protruding from the sleeve surface, thereby fixing the sleeve. According to the specific position of the rebar in the rebar cage that needs to be connected to the sleeve, the adjusting screw is rotated to drive the slider to slide along the slide rail, thereby adjusting the position of the sleeve fixed inside the clamping plate. This allows the sleeve to be quickly connected and installed with the rebar, improving the efficiency of sleeve installation and the accuracy of sleeve installation position. Accurate sleeve position adjustment ensures that the rebar in the precast column is precisely inserted into the sleeve. After grouting, a stable connection is formed between the rebar and the sleeve, effectively transferring stress and ensuring the structural integrity of the precast column when bearing vertical and horizontal loads. This reduces the safety risks caused by unreliable connections. At the same time, precise installation position helps reduce adjustments and rework during construction, making the installation of precast columns smoother and ensuring the efficient progress of the entire precast assembly construction process.

[0017] 2. In this invention, the connection between the side forming mold and the bottom template is reinforced by interlocking and fixing the three reinforcing plates. This prevents excessive pressure and deformation at the root of the side forming mold during concrete pouring. Then, by rotating the first clamping bolt, the first and third reinforcing plates are supported and reinforced on the sides, further strengthening the root of the side forming mold. Simultaneously, rotating the second clamping bolt pushes the second reinforcing plate to support and reinforce the side of the side forming mold, further improving its stability. This ensures that the side forming mold will not deform or shift when subjected to the enormous pressure, impact, and vibration during concrete pouring, effectively preventing quality problems such as column dimensional deviations and surface unevenness caused by mold deformation, and ensuring that the shape and dimensional accuracy of the column meet design requirements.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown: A grouting sleeve fixing fixture for precast column components includes a bottom template 1, a side forming mold 2 mounted on the upper part of the bottom template 1, a U-shaped groove 5 on the surface of the side forming mold 2, and a side reinforcement mechanism 4 mounted on the side of the side forming mold 2. The side reinforcement mechanism 4 is used to reinforce the connection between the bottom template 1 and the side forming mold 2. A limit adjustment mechanism 6 is provided on the side of the U-shaped groove 5. The limit adjustment mechanism 6 is fixedly connected to the outer wall of the side forming mold 2. The limit adjustment mechanism 6 is used to limit and fix the sleeve and adjust the position of the sleeve.

The slide rail 61 is fixedly connected, and a slider 62 is slidably connected inside the slide rail 61. An adjusting screw 63 is rotatably connected inside the slide rail 61. One end of the adjusting screw 63 passes through the surface of the slide rail 61 and is threadedly connected to the slider 62. Two connecting plates 64 are fixedly connected to the surface of the slider 62. The two connecting plates 64 are symmetrically distributed on the surface of the slider 62. A No. 3 clamping bolt 65 is threadedly connected to the surface of the connecting plates 64. A fixing block 66 is rotatably connected to the end of the No. 3 clamping bolt 65. A clamping plate 67 is fixedly connected to the side of the fixing block 66. A fixing plate 68 is fixedly connected to the surface of the fixing block 66. A limit rod 69 is fixedly connected to the side of the fixing plate 68. The limit rod 69 is inserted into the connecting plate 64.

[0028] In this embodiment, the bottom of the tied steel cage is wound into the side forming mold 2, and the grouting connector protruding from the surface of the sleeve is placed inside the clamping plate 67. Then, the No. 3 clamping bolt 65 is rotated to clamp and fix the grouting connector protruding from the surface of the sleeve, thereby fixing the sleeve. According to the specific position of the steel bar in the steel cage that needs to be connected to the sleeve, the adjusting screw 63 is rotated to drive the slider 62 to slide along the slide rail 61, thereby adjusting the position of the sleeve fixed inside the clamping plate 67, so that the sleeve can be quickly connected and installed with the steel bar, improving the efficiency of sleeve installation and the accuracy of sleeve installation position.

[0029] During the process of adjusting the position of the clamping plate 67 driven by the fixing block 66, the limiting rod 69 will slide along the connecting plate 64 to limit the fixing plate 68, thereby limiting the position of the clamping plate 67 and improving the stability of the clamping plate 67 when it moves. After the sleeve is fixed, the U-shaped groove hole 5 is sealed with a rubber plug to avoid the problem of grout leakage during concrete pouring.

[0030] Example 2: According to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a bottom reinforcement mechanism 3 is installed on the upper part of the bottom template 1. The bottom reinforcement mechanism 3 is used to reinforce the root of the side forming mold 2. The bottom reinforcement mechanism 3 includes four No. 3 reinforcement plates 31. One end of the No. 3 reinforcement plate 31 is fixedly connected to a plug 32, and the other end of the No. 3 reinforcement plate 31 is provided with a slot 33. The plug 32 and the slot 33 are mutually adapted. The plug 32 at the end of one No. 3 reinforcement plate 31 is inserted and fixed to the slot 33 at the end of another No. 3 reinforcement plate 31. The plug 32 is T-shaped. The side reinforcement mechanism 4 includes a base plate 41. The surface of the base plate 41 is provided with fixing bolts 42. The fixing bolts 42 are threadedly connected to the surface of the bottom template 1. The base plate 41 is fixedly connected to the bottom template 1 by fixing bolts 42. A support plate 43 is fixedly connected to the upper part of the base plate 41, and a reinforcing brace is fixedly connected at the connection between the base plate 41 and the support plate 43. A first clamping bolt 44 is threadedly connected to the surface of the support plate 43. The end of the first clamping bolt 44 is rotatably connected to a first reinforcing plate 45. The first reinforcing plate 45 is in contact with the surface of the third reinforcing plate 31. A second clamping bolt 46 is threadedly connected to the surface of the support plate 43. The second clamping bolt 46 is located above the first clamping bolt 44, and the end of the second clamping bolt 46 is rotatably connected to a second reinforcing plate 47. The second reinforcing plate 47 is in contact with the surface of the side forming mold 2.

[0031] In this embodiment, when installing and connecting the side forming mold 2 and the bottom template 1, the three reinforcing plates 31 are interlocked and fixed to each other to reinforce the root position of the connection between the side forming mold 2 and the bottom template 1. This prevents the root of the side forming mold 2 from deforming due to excessive pressure during concrete pouring. Then, by rotating the first clamping bolt 44, the first reinforcing plate 45 and the third reinforcing plate 31 are supported and reinforced on the side, further reinforcing the root of the side forming mold 2. At the same time, by rotating the second clamping bolt 46, the second reinforcing plate 47 is pushed to support and reinforce the side of the side forming mold 2, further improving the stability of the side forming mold 2.

[0032] The method of use and working principle of this device: When using this invention, the bottom of the tied steel cage is wrapped into the side forming mold 2, the grouting connector protruding from the surface of the sleeve is placed inside the clamping plate 67, and then the No. 3 clamping bolt 65 is rotated to clamp and fix the grouting connector protruding from the surface of the sleeve, thereby fixing the sleeve. According to the specific position of the steel bar in the steel cage that needs to be connected to the sleeve, the slider 62 is driven to slide along the slide rail 61 by rotating the adjusting screw 63, thereby adjusting the position of the sleeve fixed inside the clamping plate 67.

[0033] During the process of the fixed block 66 driving the clamping plate 67 to adjust its position, the limiting rod 69 will slide along the connecting plate 64 to limit the fixed plate 68, thereby limiting the position of the clamping plate 67. After the sleeve is fixed, the U-shaped groove hole 5 is sealed with a rubber plug.

[0034] When installing and connecting the side forming mold 2 and the bottom template 1, the three reinforcing plates 31 are interlocked and fixed to each other to reinforce the root position of the connection between the side forming mold 2 and the bottom template 1. This prevents the root of the side forming mold 2 from deforming due to excessive pressure during the pouring of concrete. Then, the first clamping bolt 44 is rotated to support and reinforce the side of the first reinforcing plate 45 and the third reinforcing plate 31.
