Description

Technical Field

[0001] The present invention belongs to the technical field of precast vertical component installation, and specifically relates to a support-free structure for precast vertical components. Background Art

[0002] Under the background of the rapid development of building industrialization, precast vertical components (such as precast columns, precast walls, etc.) have become the core components of prefabricated buildings due to their advantages of high efficiency, environmental protection, and controllable quality. Traditional cast-in-situ concrete vertical component construction has problems such as a large amount of on-site wet work, long construction period, high labor intensity, and serious resource waste, and is greatly affected by weather and human factors, making it difficult to ensure the uniformity of component quality. In contrast, precast vertical components can be standardized and produced in factories and then transported to the site for assembly, significantly shortening the construction period and reducing environmental pollution, which conforms to the development trend of green buildings.

[0003] A welded reinforced concrete precast vertical component with the publication number of CN112064790A uses vertically stressed steel materials that can be butt-welded on at least one side of the horizontal section of the component. The vertically stressed steel materials are steel plates or steel bars. When the reinforced concrete precast vertical component is extended, it is connected by butt-welding between the stressed steel materials of the upper and lower precast reinforced concretes.

[0004] A vertical steel bar positioning device for vertical precast components and a processing method for vertical precast components with the publication number of CN116079890A. The device includes a fixing frame, an adjusting and positioning component, and a positioning kit. The adjusting and positioning component is displaceably installed on the fixing frame. The adjusting and positioning component includes a housing, and a T-shaped adjusting rod is displaceably installed in the housing. Among them, the displacement direction of the T-shaped adjusting rod in the housing is perpendicular to the displacement direction of the adjusting and positioning component on the fixing frame. The positioning kit is installed on the part of the T-shaped adjusting rod extending out of the housing and is used to sleeve one end of the vertical steel bar of the vertical precast component.

[0005] However, there are still many bottlenecks in the existing precast vertical component technology. In terms of connection methods, traditional grouting sleeves, bolt connections and other processes require complex on-site operations. The connection quality depends on the experience of workers, and there are problems such as insufficient connection strength and low construction efficiency. In the installation link, the positioning accuracy of components is restricted by measuring tools and manual operations, and it is difficult to adjust the verticality, which is likely to cause overall structural deviation. During transportation and storage, due to the large size and high weight of components, they are prone to collision damage, affecting the installation quality. In terms of the temporary support system, the traditional support structure is complex, requiring a large amount of turnover materials, time-consuming and laborious for installation and removal, and there are safety hazards. In addition, the integrated design of precast vertical components with functions such as building insulation, waterproofing, and decoration is insufficient, making it difficult to meet the performance requirements of the building's entire life cycle. For example, in a welded reinforced concrete precast vertical component with strong anti-deformation ability, the overall structure is simple. During the construction process of the vertical component, an additional inclined support structure is required to position and support the vertical component body, so as to prevent the vertical component body from falling to the ground and causing the vertical component to break. Another example is a vertical precast component vertical steel bar positioning device and a vertical precast component processing method. The external structure of the vertical component is too much, which affects the construction use of the vertical component itself, extremely occupies steel, and increases the construction cost of the vertical component.

[0006] Therefore, in view of the above problems, a support-free structure for precast vertical components is proposed. Summary of the Invention

The vertical steel bar is inserted on the surface of the reinforcing bottom plate. There are two groups of fixing columns, which are located at the middle position of the vertical steel bar.

[0015] Preferably, after the installation and adjustment of the self - supporting component and the steel bar reinforcement component are completed, they are both mixed and poured with concrete mortar to form the overall model of the vertical component body. The self - supporting component is integrally triangular and remains triangular after docking.

[0016] Preferably, for the two symmetrically spliced self - supporting components, a buckle is welded on one side of the top of the installation frame of one self - supporting component.

[0017] Preferably, the straightening component includes a straightening plate that fits on the top of the vertical component body, and the vertical steel bar passes through the straightening plate. Fixed blocks are welded on the outer side of the straightening plate. Struts are welded on the surface of the fixed blocks. There are three groups of struts, which are respectively arranged on three faces of the vertical component body.

[0018] Preferably, the other end of the support rod is fitted with an extension sleeve. Jack holes are provided at the bottom ends of the support rod and the extension sleeve. A screw rod spirally arranged with the upper jack hole is welded above the extension sleeve, and the extension sleeve can be increased or decreased according to construction requirements.

[0019] Preferably, there are five multi-reinforcement plates. A second fastening bolt spirally arranged with the vertical member body penetrates through the surface of the rightmost multi-reinforcement plate. A docking and engaging plate is welded to one side of the leftmost multi-reinforcement plate. A card slot is provided on the other side of the multi-reinforcement plate.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. In the present invention, through the cooperation of the non-support component and the multi-reinforcement plate structure in the detachable vertical wall component, the added non-support component can form a triangular counterweight shape, shifting the structural center of gravity of the vertical member body downward to form a stable support structure, reducing the deflection of the vertical frame body during construction. Moreover, in cooperation with the structure as auxiliary reinforcement, it can improve the placement stability of the vertical member body and enhance the outer structural strength of the vertical member body to protect the vertical member body.

The same structure splicing will also reduce the production cost of the non-support component once again.

[0023] 3. In the present invention, through the fixed column structure in the steel bar reinforcement component, not only can the structural strength of the bottom plate be increased, but also a positioning point can be provided for the installation of the vertical steel bars. Moreover, during the subsequent vertical steel bar bundling operation, the steel bars can be extremely quickly bound and formed by bundling wires, avoiding the loosening of the vertical steel bars during pouring and forming.

According to specific needs, those of ordinary skill in the art can adjust or modify these devices and environments. Detailed implementation manners

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0044] It should be noted that in the specification, it is mentioned that "an embodiment", "embodiments", "exemplary embodiments", "some embodiments", etc. indicate that the described embodiments may include specific features, structures or characteristics, but not necessarily every embodiment includes such specific features, structures or characteristics. In addition, when combining embodiments to describe specific features, structures or characteristics, implementing such features, structures or characteristics in combination with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the relevant art.

[0045] As Figures 1 to 12 shown, the present invention provides a self - supporting structure for precast vertical components, including a vertical component body 1, and a triangular self - supporting component is arranged inside the vertical component body 1;

[0046] On one side of the self - supporting component, there is a steel bar reinforcement component. There are four vertical steel bars 31 in a group, and they are bundled and fixed by the side - by - side binding wires 32. After the operation is completed, the bundled binding wires 32 can be directly placed into the production mold of the vertical component body 1. The steel bar reinforcement component consists of the vertical steel bars 31 bundled and fixed by the binding wires 32;

[0047] In the construction of a support-free component applied to a large-area vertical component body 1, including two symmetrically spliced support-free components, the stability of the placement is improved by the triangular support-free components, and a straightening component is provided at the top of the vertical component body 1; on one side of the vertical component body 1, there is also a detachable vertical wall component, and the detachable vertical wall component forms a structure with a width slightly larger than that of the vertical component body 1 through assembly, so as to strengthen the stability of the vertical component body 1, where it is assembled by multiple stacked and spliced multi-reinforcement plates 51.

[0048] Specifically, the support-free component includes an installation frame 21 integrally cast with the vertical component body 1 by concrete. The installation frame 21 is hollow, and vertical steel bars 31 are inserted into the cavity of the installation frame 21. The hollow structure of the installation frame 21 can quickly position the assembled group of vertical steel bars 31, facilitating the construction personnel to quickly assemble the frame of the vertical component body 1.

[0049] On one side of the installation frame 21, a telescopic shaft 27 is welded. At the other end of the telescopic shaft 27, a reinforcement bottom plate 22 that abuts against the installation frame 21 is fixed. On the outside of the reinforcement bottom plate 22, a diagonal brace 23 is rotatably arranged. At the other end of the diagonal brace 23, a guide frame 24 fixed to the installation frame 21 is provided. The structure of the telescopic shaft 27 can be assembled by sleeving two sleeves. After stretching, the outer reinforcement bottom plate 22 can be stretched and moved, and the angle of the rotated diagonal brace 23 can be changed, making it more stable to use.

[0050] On the surface of the guide frame 24, there are jacks. Inside the jacks of the uppermost guide frame 24, a fastening bolt 25 that penetrates the diagonal brace 23 is spirally provided. Insert the fastening bolt 25 into the corresponding jack of the guide frame 24, and pass the diagonal brace 23 outside the guide frame 24 through and fix it outside the guide frame 24 to quickly fix it.

[0051] On the surface of the reinforcement bottom plate 22, a fixed column 33 is welded. At the top of the fixed column 33, a limiting plate 34 is welded. Through holes are provided on the side surface of the limiting plate 34. The positioning steel ring 35 used for bundling can pass through the through-hole structure to bundle and position the vertical steel bars 31 installed outside the through-hole. After assembly, positioning can be effectively completed. The positioning steel ring 35 is inserted into the through-hole of the limiting plate 34, and the positioning steel ring 35 is wound around the outside of the vertical steel bars 31 and welded before concrete pouring. And the vertical steel bars 31 are inserted into the surface of the reinforcement bottom plate 22. There are two groups of fixed columns 33, and they are located at the middle position of the vertical steel bars 31. The two groups of fixed column 33 structures can simultaneously position two groups of vertical steel bars 31.

[0052] After the installation and adjustment of the self-supporting component and the steel bar reinforcement component are completed, they are both poured into the overall model of the vertical component body 1 by mixing with concrete mortar. The self-supporting component is integrally triangular and remains triangular after docking. The triangular self-supporting component cooperates with the steel bar reinforcement component structure, which can improve the structural strength and stability of the vertical component body 1. When producing a wider vertical component body 1, the structures of two adjacent installation frames 21 can be pressed and positioned together through the buckle 26 structure to form a stable positioning structure and maintain the structural strength of the vertical component body 1.

[0053] Two symmetrically spliced self-supporting components are selected. On one side, a buckle 26 is welded on the top side of the installation frame 21 of the self-supporting component. The symmetric installation frames 21 are clamped through the buckle 26. And notch grooves are opened at the corresponding positions on the top of the adjacent installation frames 21. The added notch groove structure can cooperate with the buckle 26 structure to be butt-jointed and clamped with each other, which has stronger positioning connection stability for the two installation frames 21 and can be welded after reinforcement to further improve the structural strength.

[0054] The straightening component includes a straightening plate 41 attached to the top of the vertical component body 1, and the vertical steel bar 31 passes through the straightening plate 41. Through holes corresponding to the vertical steel bar 31 are opened on the surface of the straightening plate 41. A fixing block 42 is welded on the outside of the straightening plate 41, and a support rod 43 is welded on the surface of the fixing block 42. The support rod 43 structure is arranged on the outside of the straightening plate 41. The straightening plate 41 is pushed open through the support rod 43. There are three groups of support rods 43, which are respectively arranged on three faces of the vertical component body 1. The structural design of the three faces can prevent the situation of skew when pushing the straightening plate 41, resulting in the problem that the straightening plate 41 pushes the vertical steel bar 31 to be inclined.

[0055] The other end of the support rod 43 is attached with an extension sleeve 45. Insertion holes 44 are opened at the bottom ends of the support rod 43 and the extension sleeve 45. The extension sleeve 45 is screwed into the insertion hole 44 of the support rod 43 through a screw 46. A screw 46 spirally arranged with the upper insertion hole 44 is welded above the extension sleeve 45, and the extension sleeve 45 can be increased or decreased according to the construction requirements. When the ground is flat, the corresponding length of the extension sleeve 45 structure can be increased according to the length of the vertical steel bar 31. When supporting on the ground, the straightening plate 41 can be directly pushed open from the outside of the vertical steel bar 31.

[0056] There are five multi-reinforcement plates 51. According to the usage requirements, the corresponding multi-reinforcement plates 51 can be flexibly increased or decreased. By increasing or decreasing the multi-reinforcement plates 51, the thickness can be changed. In order to increase the stability of the installation of the vertical member body 1 through the T-shaped shape, other vertical member bodies 1 can also be assembled to one side of the multi-reinforcement plates 51. A second fastening bolt 52 spirally arranged with the vertical member body 1 penetrates through the surface of the rightmost multi-reinforcement plate 51. A butt joint engaging plate 54 is welded on one side of the leftmost multi-reinforcement plate 51. The second fastening bolt 52 is used to fix adjacent multi-reinforcement plates 51. Generally, two groups of second fastening bolts 52 are installed. A clamping groove 53 is formed on the other side of the multi-reinforcement plate 51. Adjacent multi-reinforcement plates 51 are inserted through the butt joint engaging plate 54 and the clamping groove 53. A third fastening bolt 55 spirally arranged with it penetrates through the butt joint engaging plate 54. The butt joint engaging plate 54 is set as an irregular wedge shape. The use of the irregular wedge-shaped structure makes the installation more firm. The multi-reinforcement plate 51 is made of steel plate. After the third fastening bolt 55 is fixed, adjacent multi-reinforcement plates 51 can be welded by welding to enhance the structural strength in the later construction stage and reduce the generation of gaps, thus avoiding the problem of water leakage in the later stage.

[0057] The working principle of the technical solution provided by the present invention:

[0058] The precast vertical member free-support structure is coordinated by multiple components. The free-support component mainly serves as the main framework of the vertical member body 1. After the vertical steel bars 31 of the steel bar reinforcement component are tied into shape by tying wires 32, they are combined with the reinforcement bottom plate 22 and the installation frame 21 of the free-support component to form an overall general framework. Then, concrete is poured in the mold. After solidification, the whole vertical member body 1 is formed, realizing free-support installation and stability. During the construction process of the precast vertical member body 1, the traditional support system is cumbersome, time-consuming and costly. However, in the free-support structure provided by the present invention, through the ingenious design of the cooperation of each component, the vertical steel bars 31 are quickly solidified into shape, effectively solving the above problems and realizing the stable installation and construction of the precast vertical member.

[0059] Installation and Fixation of the Support-Free Component: Before construction, the installation frame 21 and the vertical member body 1 are integrally cast with concrete to form a stable foundation. The telescopic shaft 27 of the installation frame 21 can adjust the extended length. The reinforcement base plate 22 is extended to be close to the other end of the vertical member body 1 and is maximally unfolded inside the vertical member body 1. The triangular support structure formed by the reinforcement base plate 22 and the installation frame 21 provides an initial support force for the entire support-free component. Subsequently, the diagonal brace 23 is rotated so that the connecting plate at one end thereof is placed on the guide frame 24. By screwing the first fastening bolt 25 into the jacking hole of the guide frame 24, the first fastening bolt 25 passes through the connecting plate of the diagonal brace 23 to fix the diagonal brace 23, forming a triangular stable structure to enhance the overall stability of the support-free component. And during the construction operation of the vertical member body 1 with a larger width, the length of the vertical member body 1 produced can be counted. Multiple groups of support-free components are symmetrically assembled through the adjacent installation frames 21 by the buckles 26 to form a larger triangular structure, so as to fill and position it inside the vertical member body 1, and a stable fixing member is formed by concrete pouring, and the structural strength of the vertical member body 1 can still be maintained.

[0060] Cooperation of the Reinforcement Component: After the vertical reinforcement bars 31 are bundled and fixed by the bundling wires 32, they are inserted into the cavity of the installation frame 21, and their bottoms are inserted and connected to the surface of the reinforcement base plate 22. The outer fixed columns 33 to which the vertical reinforcement bars 31 are positioned are provided. The vertical reinforcement bars 31 are abutted against the surfaces of the fixed columns 33 and the limit plates 34 to provide lateral support for the vertical reinforcement bars 31. The positioning steel rings 35 are passed through the holes of the limit plates 34, and the positioning steel rings 35 are wound around the outer sides of the vertical reinforcement bars 31 and welded and fixed to further ensure the accurate position of the reinforcement bars and prevent the reinforcement bars from shifting during the pouring process. During the concrete pouring, the support-free component and the reinforcement component are poured together, and the two cooperate with each other to make the vertical member body 1 have reliable mechanical properties.

[0061] Splicing and Straightening of Multiple Components: For large-area vertical members, two symmetrically spliced support-free components are selected, and the adjacent installation frames 21 are clamped and fixed by the buckles 26. The notch groove design facilitates the accurate docking of the components. The straightening component plays a role at the top of the vertical member. The straightening plate 41 fits the top of the member, and the vertical reinforcement bars 31 pass through the straightening plate 41. The three sets of struts 43 support the straightening plate 41 from three surfaces respectively. By adjusting the screw rod 46 of the extension sleeve 45, the position of the straightening plate 41 can be flexibly adjusted to ensure that the verticality of the vertical member meets the construction requirements.

[0062] Installation of the detachable vertical wall component: The detachable vertical wall component is formed by stacking and splicing multiple reinforcement plates 51. During installation, insert the docking and biting plate 54 of the left-side multiple reinforcement plates 51 into the card slot 53 of the adjacent multiple reinforcement plates 51, screw in the third fastening bolt 55 for preliminary fixation, and then further strengthen the connection through welding. The rightmost multiple reinforcement plate 51 is helically fixed to the vertical member body 1 through the second fastening bolt 52 to form a complete vertical wall structure, providing additional lateral support and protection for the vertical member.

[0063] Through the coordinated operation of the above-mentioned non-support component, steel bar reinforcement component, straightening component and detachable vertical wall component, the present invention realizes that the precast vertical member does not require a traditional support system during the construction process, which not only ensures the stability and accuracy of the component installation, but also simplifies the construction process, improves the construction efficiency and reduces the construction cost.
