Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a fixing device for building embedded parts. Background Art

[0002] In housing construction, the installation and fixation of the railing base is a critical aspect of railing installation, as its stability directly impacts the reliability of the railing's protective capabilities. Currently, the main methods for installing railing bases are: 1. Punching holes in the upper surface after the main structure is formed; 2. Pre-embedded components for connecting the railing base plate before the main structure is formed. The former method results in less stable railing base installation than the latter.

[0003] For the latter, the existing technology has embedded parts at the bottom of the stair railing. During the stage of stair tread formwork and steel bar tying, the embedded components are placed in the stair main body. The upper surface of the embedded components is flush with the upper formwork of the stair treads. The embedded components are temporarily fixed by punching holes in the upper formwork and become one with the stair main body after pouring concrete.

[0004] The existing embedded components have at least the following defects: 1. After the stair railing is installed, its bottom is exposed, which affects the appearance and requires a flange ring to cover it up; 2. The existing embedded components are not suitable for edge protection of stairs and cannot consider the combination of permanent and temporary stair protection. Utility Model Content

[0005] The purpose of the utility model is to provide a fixing device for building embedded parts, so as to solve the technical problems existing in the prior art that the bottom of the stair railing is exposed after installation, affecting the appearance, and the existing embedded components are not suitable for edge protection of stairs.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A fixing device for building embedded parts, comprising a conical cylinder, a fixing plate and a plurality of connecting bolts, wherein:

[0008] The conical cylinder is an inverted conical shell structure from top to bottom, and the top of the conical cylinder is open;

[0009] The fixing plate is connected to the bottom of the conical cylinder;

[0010] A plurality of connecting bolts are fixed on the fixing plate, and the connecting bolts extend into the conical cylinder.

[0011] Furthermore, the conical cylinder and the fixing plate are detachably connected.

[0012] Furthermore, it also includes a sealing strip, the bottom of the conical cylinder is open, and the sealing strip is adhered to the joint between the conical cylinder and the fixing plate;

[0013] Alternatively, the conical cylinder includes a bottom plate and a side plate arranged around the circumference of the bottom plate, and the bottom plate can be fixedly connected to the fixing plate by the connecting bolts.

[0014] Furthermore, it also includes a plurality of legs fixed below the supporting base plate.

[0015] Furthermore, the fixing plate, the connecting bolts and the supporting legs are fixedly connected by welding.

[0016] Furthermore, the fixing plate is provided with a plurality of connecting holes, and the connecting bolts correspond to and are inserted into the connecting holes one by one.

[0017] Furthermore, the conical cylinder is made of aluminum plate or plastic plate.

[0018] Furthermore, the fixing plate is made of steel plate.

[0019] Furthermore, the tapered cylinder is in the shape of a pyramid or a cone.

[0020] Furthermore, the outer surface of the conical cylinder is coated with an anti-sticking layer.

[0021] Beneficial effects of the utility model:

[0022] The utility model provides a fixing device for building embedded parts, which includes a conical cylinder, a fixing plate and a plurality of connecting bolts, wherein: the conical cylinder is an inverted conical shell structure from top to bottom, and the top of the conical cylinder is open; the fixing plate is connected to the bottom of the conical cylinder; and the plurality of connecting bolts are fixed on the fixing plate, and the connecting bolts extend into the conical cylinder.

[0023] After casting, the device becomes an integral part of the staircase body. The top opening of the conical tube is flush with the top floor of the structure, and an inverted cone-shaped area is formed between the conical tube and the fixing plate for the bottom of the handrail to extend into. The base plate on the handrail can be fixed to the fixing plate via connecting bolts, thereby securing the handrail. After the handrail is secured, the base plate is hidden within the inverted cone-shaped area between the conical tube and the fixing plate. A secondary pour of concrete can be used later to achieve secondary fixation and complete concealment, allowing the embedded parts and base plate to be fully embedded in the structural layer. Flange rings are no longer necessary to conceal the ugliness, ensuring not only the stability and wind resistance of the handrail installation but also the aesthetics of the handrail through one-step molding. Furthermore, before the handrail is formally installed, the device can also be used for edge protection at stairs and other locations. Connecting bolts are used to effectively connect the bottom or end of the edge protection to the embedded parts, improving the safety of the edge protection and achieving a permanent connection.

[0039] Example 1

[0040] The first embodiment of the utility model provides a fixing device for building embedded parts, referring to Figures 1 to 3 The device comprises a conical cylinder 1, a fixing plate 2 and a plurality of connecting bolts 3, wherein:

[0041] The conical cylinder 1 is an inverted conical shell structure from top to bottom, and the top of the conical cylinder 1 is open;

[0042] The fixing plate 2 is connected to the bottom of the conical cylinder 1;

[0043] A plurality of connecting bolts 3 are fixed on the fixing plate 2 , and the connecting bolts 3 extend into the conical cylinder 1 .

[0044] like Figure 3As shown, after the casting is completed, the device is integrated with the main body of the staircase. The top opening of the conical tube 1 is located in the same plane as the top floor of the structure. An inverted cone-shaped area is formed between the conical tube 1 and the fixing plate 2 for the bottom of the handrail 100 to extend into. The handrail base plate 200 on the handrail 100 can be fixed to the fixing plate 2 by connecting bolts 3, thereby achieving the fixation of the handrail 100. After the handrail 100 is fixed, the handrail base plate 200 is hidden in the inverted cone area between the conical tube 1 and the fixing plate 2. The subsequent secondary pouring of concrete can achieve secondary fixation and complete concealment, so that the embedded parts and the handrail base plate 200 are completely embedded in the structural layer, and there is no need to use flange rings to cover up the ugliness. This not only ensures the stability and wind resistance of the handrail 100 during installation, but also improves the aesthetics of the handrail 100 through one-step molding. In addition, before the formal installation of the handrail 100, the device can also be used for edge protection at stairs and other places. The bottom or end of the edge protection is effectively connected to the embedded parts through the connecting bolts 3, which improves the safety of the edge protection and realizes permanent connection.

[0045] The building embedded part fixing device further includes a plurality of nuts 6 , which correspond one to one and are screwed to the connecting bolts 3 . The railing base plate 200 can be fixed to the fixing plate 2 via the connecting bolts 3 and the nuts 6 .

[0046] In this embodiment, the fixing plate 2 is provided with a plurality of connection holes, and the connection bolts 3 are correspondingly inserted into the connection holes. Specifically, the fixing plate 2 is provided with four connection holes in the middle position, and four high-strength connection bolts 3 are inserted into the four connection holes from bottom to top, and are welded together.

[0047] Optionally, the conical cylinder 1 is made of aluminum plate or plastic plate; the fixing plate 2 is made of steel plate. The raw materials used in the device are all common materials in engineering, which are easy to obtain and the processing technology is simple and fast.

[0048] Reference Figure 2 In this embodiment, the conical tube 1 is in the shape of a pyramid and can be assembled from multiple plates. For example, the conical tube 1 is assembled using four inverted trapezoidal aluminum plates or engineering plastic plates to form an inverted quadrangular pyramid-shaped conical structure, and the joints between two adjacent plates are welded.

[0049] Continue to refer to Figure 3 The building embedded part fixing device further comprises a plurality of legs 5 fixed below the fixing plate 2. In this embodiment, the number of the legs 5 is four and they are evenly spaced around the axis of the conical cylinder 1.

[0050] Furthermore, the legs 5 are formed by bending steel bars, and the upper ends of the legs 5 are fixed to the bottom of the fixing plate 2. The fixing plate 2, the connecting bolts 3 and the legs 5 are fixedly connected by welding.

[0051] Due to the provision of the legs 5, the embedded part can be bent and anchored with the concrete structure through the legs 5, thereby improving the sturdiness and wind resistance of the handrail 100 after installation. In addition, the embedded part can be flexibly installed and is suitable for various occasions, not only for reinforced concrete, steel structures, and aluminum molded stair treads, but also for balconies with railing designs, roof parapets, and parapets.

[0052] For reinforced concrete wooden formwork and aluminum formwork stair treads, balconies and roof parapets, the device is installed as follows: the legs 5 at the bottom of the embedded parts are welded and fixed to the structural design steel bars during the steel bar binding and formwork support stages, and secondary fixation is achieved after pouring concrete.

[0053] For steel structure stair treads, the device is installed in the following manner: the legs 5 at the bottom of the embedded parts are welded to the steel template at the bottom of the treads.

[0054] For the guardrail, the device is installed in the following way: cutting or reserving a notch on the wall, installing the embedded parts in the precast concrete blocks with the corresponding notch size, and consolidating the precast concrete blocks in the wall through the plastering process.

[0055] Furthermore, the conical cylinder 1 and the fixing plate 2 are detachably connected. That is, the conical cylinder 1 can be disassembled before the secondary pouring and can be reused, thereby increasing the workpiece turnover rate and reducing construction costs.

[0056] On the basis of the above structure, the outer surface of the conical tube 1 is coated with an anti-sticking layer to facilitate the removal of the conical tube 1 .

[0057] In this embodiment, the building embedded component fixing device further includes a sealing strip 4. The bottom of the conical tube 1 is open, and the sealing strip 4 is adhered to the joint between the conical tube 1 and the fixing plate 2. The sealing strip 4 can be a sponge sealing strip, which is adhered to the periphery of the joint between the conical tube 1 and the fixing plate 2. On the one hand, it allows the conical tube 1 to be detachably fixed to the fixing plate 2, and on the other hand, it improves the sealing performance of the joint between the conical tube 1 and the fixing plate 2.

[0058] Optionally, a sealing strip 4 is adhered to the outer ring of the joint between the conical cylinder 1 and the fixed plate 2 , and / or a sealing strip 4 is adhered to the inner ring of the joint between the conical cylinder 1 and the fixed plate 2 .

[0059] Example 2

[0060] The difference between this embodiment and the first embodiment is that: Figure 4 In this embodiment, the tapered barrel 1 is in a conical shape. The conical configuration makes it easier to disassemble the tapered barrel 1.

[0061] Example 3

[0062] This embodiment is an extension of any of the above embodiments. Figure 5 In this embodiment, the periphery of the bottom opening of the conical tube 1 is provided with a flange 13 facing the interior of the conical tube 1, and the bottom surface of the flange 13 abuts against the fixed plate 2. This arrangement increases the contact area between the conical tube 1 and the fixed plate 2, thereby improving the connection strength between the conical tube 1 and the fixed plate 2.

[0063] Example 4

[0064] The difference between this embodiment and the above embodiment is that: Figure 6 In this embodiment, the bottom of the conical tube 1 is not open. That is, the conical tube 1 includes a bottom plate 11 and a side plate 12 arranged around the bottom plate 11; the bottom plate 11 can be fixedly connected to the fixing plate 2 by connecting bolts 3.

[0065] Specifically, the bottom plate 11 and the side plates 12 are welded together; a plurality of holes are provided through the middle of the bottom plate 11 , and the connecting bolts 3 can penetrate the holes on the bottom plate 11 from bottom to top and be fixed by the nuts 6 .

[0066] On the basis of the above structure, in this embodiment, a sealing strip 4 may be adhered to the outer ring of the joint between the conical cylinder 1 and the fixing plate 2 to prevent concrete from penetrating.

[0067] Example 5

[0068] This embodiment is an extension of any of the above embodiments. Figure 7 In this embodiment, a plurality of ribs 14 are provided in the conical tube 1. This configuration not only improves the structural strength of the conical tube 1 and prevents deformation of the conical tube 1, but also allows the operator to pull out the conical tube 1 by the ribs 14, facilitating disassembly of the conical tube 1.

[0069] On the basis of the above structure, both ends of the rib 14 are welded to the inner wall surface of the conical cylinder 1 respectively.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
