Description

Technical Field

[0001] The utility model relates to the field of pre-embedded auxiliary components for steel structure column foot bolts, in particular to a pre-embedded part for steel structure column foot bolts. Background Art

[0002] Steel structure has the advantages of light weight, good seismic performance, high strength, good plasticity and toughness, fast construction speed, etc., so its application in engineering projects is becoming more and more common. Specifically in the construction process of steel structure, the column foot is the foundation of the steel structure building. Before installation, the column foot bolts need to be pre-embedded to ensure that the steel structure column foot can be firmly fixed in the setting position.

[0003] The existing steel structure column foot bolts are pre-buried in the following two methods. One is to insert the column foot bolts into the foundation column one by one after the foundation concrete is poured and before the concrete has initially set. This pre-buried construction method is very random and has poor accuracy, which often leads to serious deviation of the bolt axis position and insufficient or excessive exposed length of the bolt thread head. The other is to fix a single bolt in the foundation column template after drilling a hole in the square wood. However, this method is easy to cause the bolt to be skewed during the concrete pouring process because the wood is soft in texture and is easily displaced with the scaffolding steel pipe. Utility Model Content

[0004] The purpose of the utility model is to provide a steel structure column base bolt embedded part in order to solve the above-mentioned problem. A bottom support assembly is arranged at the bottom of the column base bolt body. The column base bolt body can be firmly and uprightly fixed on the top of the pad by coaxially matching the bottom of the column base bolt body with the fixing hole of the fixing seat. At the same time, the pad can be stably placed in the foundation embedded position through the support rod at the bottom of the pad, thereby ensuring that the column base bolt body can be in an upright setting state when embedded. See the following description for details.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The utility model provides a steel structure column foot bolt embedded part, comprising a column foot bolt body, wherein the column foot bolt body is in a plurality of numbers, and the bottom ends of the plurality of column foot bolt bodies are all fixed on the top of a bottom support assembly, so as to stably and uprightly fix the column foot bolt bodies through the bottom support assembly;

[0007] The adjacent column foot bolt bodies are combined and connected with a limit tensioning assembly, which is used to limit and pull the corresponding column foot bolt body through the two ends of the limit tensioning assembly.

[0008] Preferably, the bottom support assembly includes a pad and a fixing seat, the fixing seat is fixed at the corners of the top surface of the pad, the top surface of the fixing seat is vertically opened with fixing holes, and the fixing holes are coaxially fixed with the upright column foot bolt bodies, the bottom surface of the pad is vertically fixed with mounting sleeves, and the mounting sleeves are coaxially fixed with support rods extending vertically downward.

[0009] Preferably, the pad is a plate in the shape of a rectangular frame, and the fixing seat and the mounting sleeve are evenly distributed in the circumferential direction.

[0010] Preferably, the installation sleeves are all internally threaded sleeves, the support rods are all screw rods, and the support rods and the installation sleeves are combined and connected by threaded matching.

[0011] Preferably, the limiting tensioning assemblies include a force-applying base block and a matching sleeve. The force-applying base block is arranged at the middle position between adjacent column base bolt bodies. Threaded sleeves are coaxially extended and fixed on both sides of the force-applying base block. The inner circumferences of the threaded sleeves at both sides are coaxially threadedly matched with limiting screws, and the thread rotation directions of the limiting screws at both sides are symmetrical to each other. The limiting screws at both sides are away from each other and extend out to positions corresponding to the outer ends of the threaded sleeves. The matching sleeves are fixed with the matching sleeves arranged vertically along the axis through the connecting sleeves, and the matching sleeves are coaxially slidably fitted on the outer periphery of the column base bolt bodies.

[0012] Preferably, the portion of the limiting screw extending out from the outer end of the corresponding threaded sleeve is coaxially engaged with a clamping nut.

[0013] Preferably, the force-applying base blocks are all in an external hexagonal shape.

[0014] Preferably, the clamping nuts are all hand-tightened knurled nuts.

[0015] The above-mentioned steel structure column base bolt embedded part is adopted, specifically in the process of pre-embedded arrangement of the column base bolt body, since the bottom support assembly is arranged at the bottom of the plurality of column base bolt bodies, the column base bolt body can be firmly and uprightly fixed to the top corner positions of the base plate by coaxially cooperating with the fixing holes of the fixing seat at the bottom of the column base bolt body, and the base plate can be stably placed in the foundation pre-embedded position through the support rod at the bottom of the base plate, thereby ensuring that the column base bolt body can be in an upright setting state when pre-embedded, and avoiding the situation that the column base bolt body is moved and changed in position during the pouring of concrete, which is conducive to ensuring that the column base bolt body is smoothly pre-embedded. Since the limiting tensioning assembly is combined and connected between adjacent column base bolt bodies, the corresponding column base bolts are limited and pulled by the two ends of the limiting tensioning assembly. The main body method can avoid the situation where the column base bolt body has axial position deviation during the pre-embedding process, and is also conducive to avoiding the situation where the column base bolt body is skewed and deformed during subsequent use, thereby improving the stability of the column base bolt body during later use. When it comes to the actual use of the limit tensioning assembly, the threaded sleeves are coaxially fixed to the two sides of the force base block of the limit tensioning assembly, and the threaded sleeves are coaxially meshed with the limit screws, and the thread rotation directions of the limit screws at the two sides are symmetrical to each other. Then, by twisting the force base block, the limit screws at the two sides can be synchronously approached or moved away from each other, thereby enabling the limit tensioning assembly to be smoothly set between adjacent column base bolt bodies of different spacing widths, and at the same time, the tensioning degree of the column base bolt body can be adjusted to ensure that the column base bolt body is stably in an upright state.

[0016] The beneficial effects are as follows: 1. The utility model is provided with a bottom support assembly at the bottom of the column foot bolt body, and the column foot bolt body can be stably and uprightly fixed on the top of the pad by coaxially matching the bottom of the column foot bolt body with the fixing hole of the fixing seat, and the pad can be stably placed in the foundation pre-embedded position by the support rod at the bottom of the pad, thereby ensuring that the column foot bolt body can be in an upright setting state when pre-embedded, and avoiding the situation that the column foot bolt body is disturbed and changed in position during the pouring of concrete, which is conducive to ensuring that the column foot bolt body completes the pre-embedded setting smoothly;

[0017] 2. The adjacent column foot bolt bodies are combined and connected with limited tensioning components, so that the two ends of the limited tensioning components respectively limit and pull the corresponding column foot bolt bodies, which can avoid the axial position deviation of the column foot bolt body during the pre-embedding process, and at the same time, it is beneficial to avoid the column foot bolt body from being skewed and deformed during the subsequent use, thereby improving the stability of the column foot bolt body during the later use;

[0018] 3. Threaded sleeves are coaxially fixed on both sides of the force base block of the limit tensioning assembly. At the same time, the threaded sleeves are coaxially engaged with the limit screws, and the thread rotation directions of the limit screws on both sides are symmetrical to each other.

[0030] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0031] See also Figure 1-Figure 8 As shown, the utility model provides a steel structure column foot bolt embedded part, including a column foot bolt body 1, the number of column foot bolt bodies 1 is multiple, the bottom ends of the multiple column foot bolt bodies 1 are fixed to the top of the bottom support assembly 2, and the column foot bolt bodies 1 are all firmly fixed upright through the bottom support assembly 2. Specifically, the bottom support assembly 2 includes a pad 203 and a fixing seat 202, the top corners of the pad 203 are fixed with the fixing seat 202, the top surface of the fixing seat 202 is vertically opened with a fixing hole 201, and the fixing hole 201 is coaxially fixed with a column foot bolt body 1 set upright, and the bottom edge of the pad 203 is fixed with a fixing hole 201. The corner positions are all vertically fixed with mounting sleeves 204, and the mounting sleeves 204 are coaxially fixed with support rods 205 extending vertically downward. The purpose of such a setting is that the column base bolt body 1 can be firmly and uprightly fixed on the top of the pad 203 by coaxially matching the bottom of the column base bolt body 1 with the fixing hole 201 of the fixing seat 202, and the pad 203 can be stably placed in the pre-embedded position of the foundation through the support rod 205 at the bottom of the pad 203, thereby ensuring that the column base bolt body 1 can be in an upright state when pre-embedded, and avoiding the column base bolt body 1 from moving around and changing its position during the pouring of concrete.

[0032] See also Figure 1-Figure 4As shown, the adjacent column base bolt bodies 1 are combined and connected with the limited tensioning components 3, which are used to limit and pull the corresponding column base bolt bodies 1 through the two ends of the limited tensioning components 3. Specifically, the limited tensioning components 3 include a force base block 305 and a matching sleeve 301. The middle position between the adjacent column base bolt bodies 1 is provided with a force base block 305, and both sides of the force base block 305 are coaxially extended and fixed with threaded sleeves 304. The inner peripheries of the threaded sleeves 304 at the two side positions are coaxially threadedly matched with the limited screw rods 303, and the thread rotation directions of the limited screw rods 303 at the two side positions are symmetrical to each other. The limited screw rods 303 at the two side positions are away from each other and extend out of the corresponding threaded sleeves 304. The outer ends are fixed with the matching sleeves 301 arranged vertically with the axis through the connecting sleeves 302. Preferably, the connecting sleeve 302 and the corresponding limiting screw 303 are coaxially interference fit, and the connecting sleeve 302 is welded to the outer periphery of the corresponding matching sleeve 301, and the matching sleeve 301 is coaxially slidably fitted on the outer periphery of the adjacent column base bolt body 1. The effect of such a setting is that, firstly, the two ends of the limiting and tightening component 3 respectively limit and pull the corresponding column base bolt body 1, so as to avoid the axial position deviation of the column base bolt body 1 during the pre-embedding process. At the same time, by twisting the force base block 305, the limiting screws 303 on both sides can be synchronously approached or moved away from each other, so that the limiting and tightening component 3 can be smoothly set between adjacent column base bolt bodies 1 with different spacing widths, and the tightening degree of the column base bolt body 1 can also be adjusted.

[0033] See also Figure 1-Figure 4 As shown, the bottom support assembly 2 is optimized as follows: the pad 203 is a rectangular frame-shaped plate, and the fixing seat 202 and the mounting sleeve 204 are evenly arranged in the circumferential direction. This arrangement facilitates the pouring of concrete after the pad 203 and the column foot bolt body 1 are placed in the pre-embedded position of the foundation. The poured concrete can smoothly enter and fill the position below the bottom of the pad 203, ensuring that the pouring process is carried out smoothly and it is not easy to pour and fill in the position. At the same time, optionally, the mounting sleeve 204 is an internal thread sleeve, the support rod 205 is a screw rod, and the support rod 205 and the mounting sleeve 204 are combined and connected by a threaded matching method. In this way, when the pad 203 and the column foot bolt body 1 are placed in the pre-embedded position of the foundation, the pad 203 can be adjusted to a flat state in the pre-embedded position of the foundation by rotating a plurality of support rods 205 respectively, thereby ensuring that the column foot bolt body 1 on the top of the pad 203 can be in an upright state at the beginning.

[0034] See also Figure 1-Figure 4As shown, the limiting tensioning assembly 3 is optimized as follows. The portion of the limiting screw 303 extending out of the corresponding threaded sleeve 304 outer end is coaxially meshed with a clamping nut 306. The purpose of this arrangement is that when the matching sleeves 301 at both ends tighten the adjacent column base bolt bodies 1 by rotating the force base block 305, the clamping nut 306 is pressed against the outer end of the threaded sleeve 304 by twisting, so that the force base pit cannot rotate freely, and then the limiting tensioning state of the adjacent column base bolt bodies 1 can be locked. At the same time, the force base blocks 305 can be selected to be all external hexagonal in shape, so that the force base blocks 305 can be smoothly twisted with the help of tools such as wrenches. Further, the clamping nuts 306 can be selected to be all hand-tightened knurled nuts. Such an arrangement makes it easy for the clamping nuts 306 to be directly tightened or loosened by hand.

[0035] By adopting the above structure, specifically in the process of pre-embedded arrangement of the column base bolt body 1, since the bottom support assembly 2 is arranged at the bottom of the plurality of column base bolt bodies 1, the column base bolt body 1 can be firmly and uprightly fixed at the top corner position of the pad 203 by coaxially cooperating with the fixing hole 201 of the fixing seat 202 at the bottom of the column base bolt body 1, and the pad 203 can be stably placed at the pre-embedded position of the foundation through the support rod 205 at the bottom of the pad 203, thereby ensuring that the column base bolt body 1 can be in an upright setting state when pre-embedded, and at the same time, the column base bolt body 1 is prevented from being moved and changed in position during the pouring of concrete, which is conducive to ensuring that the column base bolt body 1 is smoothly pre-embedded. Since the adjacent column base bolt bodies 1 are combined and connected with the limited tensioning assembly 3, the corresponding column base bolt body 1 can be limitedly pulled by the two ends of the limited tensioning assembly 3. This avoids the situation where the column base bolt body 1 has an axial position deviation during the pre-embedding process, and is also beneficial to avoid the situation where the column base bolt body 1 is skewed and deformed during subsequent use, thereby improving the stability of the column base bolt body 1 during later use. When it comes to the actual use of the limit tensioning assembly 3, the threaded sleeves 304 are coaxially fixed on both sides of the force base block 305 of the limit tensioning assembly 3, and the threaded sleeves 304 are coaxially engaged with the limit screws 303, and the thread rotation directions of the limit screws 303 on both sides are symmetrical to each other. Then, by twisting the force base block 305, the limit screws 303 on both sides can be synchronously moved closer to or away from each other, thereby enabling the limit tensioning assembly 3 to be smoothly set between adjacent column base bolt bodies 1 with different spacing widths, and at the same time, the tensioning degree of the column base bolt body 1 can be adjusted to ensure that the column base bolt body 1 is stably in an upright state.

[0036] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
