Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a connection structure for precast concrete parapets. Background Technology

[0002] Prefabricated buildings are a new type of building production method that integrates various business areas such as R&D design, production and manufacturing, and on-site assembly, with standardized design, factory production, assembly construction, integrated decoration and information management as its characteristics, and the production of building products. It achieves energy conservation, environmental protection and full life cycle value maximization.

[0003] A balustrade is a component in a building that serves as a protective enclosure, preventing people from falling during normal use of the building. It is a type of board-shaped railing facility that is closed and continuous. Balustrades are generally made of materials such as cement and marble, and have high sturdiness. Precast balustrade walls, on the other hand, are all or most of the balustrade wall components that are prefabricated in a factory.

[0004] In existing technology, multiple grouting sleeve structures are pre-set at the bottom of the precast parapet. The protruding ends of the reinforcing bars are reserved on the assembly ground of the precast parapet. During installation, several ends of the reinforcing bars are fitted into the grouting sleeves one by one, and then grout is injected into the inside of the grouting sleeves to achieve fixation. The problem with existing technology is that because the hole diameter of the grouting sleeves is small, there are errors in the distance between the reserved ends of the reinforcing bars during on-site construction. This can easily cause multiple grouting sleeves to fail to accurately fit the ends of the reinforcing bars, resulting in rework or problems such as adjacent parapets not fitting tightly together, which affects the smooth progress of construction.

[0005] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0006] To address the problem in existing technologies where precast parapets are fixed by using multiple grouting sleeves to fit and grout the ends of pre-reserved reinforcing bars on the assembly ground, the small diameter of the grouting sleeves leads to errors in the distance between the ends of the pre-reserved reinforcing bars during on-site construction. This can result in multiple grouting sleeves not being accurately fitted to the ends of the reinforcing bars, causing rework or preventing adjacent parapets from fitting tightly together and affecting the smooth progress of construction, this utility model proposes a connection structure for precast concrete parapets.

[0007] This utility model is achieved through the following technical solution:

[0039] In existing technology, multiple grouting sleeve structures are pre-set at the bottom of the precast parapet. The protruding ends of the reinforcing bars are reserved on the assembly ground of the precast parapet. During installation, several ends of the reinforcing bars are fitted into the grouting sleeves one by one, and then grout is injected into the inside of the grouting sleeves to achieve fixation. The problem with existing technology is that because the hole diameter of the grouting sleeves is small, there are errors in the distance between the reserved ends of the reinforcing bars during on-site construction. This can easily cause multiple grouting sleeves to fail to accurately fit the ends of the reinforcing bars, resulting in rework or problems such as adjacent parapets not fitting tightly together, which affects the smooth progress of construction.

[0040] Based on the aforementioned problems in the existing technology, such as Figure 1 and Figure 2 As shown, this utility model provides a connection structure for a precast concrete parapet, which includes: a precast parapet 100, in which a plurality of assembly holes 110 are provided, the plurality of assembly holes 110 passing through the upper and lower end faces of the precast parapet 100; an installation platform 200, on which a plurality of connecting steel bars 210 are pre-embedded, one end of the plurality of connecting steel bars 210 protruding from the installation platform 200, and the positions of the plurality of connecting steel bars 210 corresponding one-to-one with the center points of the plurality of assembly holes 110.

[0041] This utility model provides greater tolerance for errors by setting assembly holes 110 through the upper and lower ends of the precast parapet 100 and pre-embedding several corresponding connecting steel bars 210 on the installation platform 200. During assembly, the connecting steel bars 210 are fitted into the corresponding assembly holes 110 and then grouting is used to fix them. Compared with the traditional grouting sleeve connection method, this provides greater tolerance for errors and provides adjustment margin for the docking of adjacent precast parapet 100s. It also reduces the accuracy requirements for the position of the pre-embedded connecting steel bars 210, reduces rework, and improves the smoothness of construction.

[0042] In the above embodiments, such as Figure 1 and Figure 2 As shown, in the connection structure of the precast concrete parapet of this utility model, the precast parapet 100 is set on the installation platform 200. Specifically, a plurality of assembly holes 110 set in the parapet are fitted one-to-one with a plurality of connecting steel bars 210 pre-embedded on the installation platform 200, and then the connection is achieved by grouting and curing the plurality of assembly holes 110. In this embodiment, the plurality of assembly holes 110 are arranged along the length direction of the precast parapet 100, and should be set relatively evenly during the pre-setting. The connecting steel bars 210 are pre-embedded on the installation platform 200, and the position of the connecting steel bars 210 should be consistent with the length direction of the precast parapet 100. The center points of the corresponding assembly holes 110 are one-to-one. The main body of the connecting steel bar 210 is wrapped inside the installation platform 200. One end of the connecting steel bar 210 protrudes from the installation platform 200 and is set in the vertical direction, so that the precast railing 100 and the connecting steel bar 210 can be combined in the vertical direction. In this embodiment, the assembly hole 110 should be set through the upper and lower end faces of the precast railing 100. The lower end of the assembly hole 110 is used to fit and combine with the connecting steel bar 210, and the upper end of the assembly hole 110 is convenient for construction personnel to observe the combination status and is used for grouting the assembly hole 110.

[0043] In actual construction, it is inevitable that there will be slight deviations in the pre-embedded position of the connecting steel bar 210, or slight offsets in the connecting steel bar 210 due to the concrete curing process of the installation platform 200. In the traditional grouting sleeve connection technology, the above situations can easily lead to problems such as inability to install and rework. In this embodiment, since the assembly hole 110 is used instead of the grouting sleeve, the diameter of the assembly hole 110 is relatively larger than that of the grouting sleeve, thereby providing a higher fault tolerance and adjustment space, so that construction personnel can adjust the installation position of the precast parapet 100 according to the site conditions. In a specific embodiment of this utility model, the radius of the assembly hole 110 should be at least 5 cm larger than the radius of the connecting steel bar 210. For example, in the prior art, steel bars with diameters of 18 mm and 20 mm are usually used for concrete components with large structural areas and great stress. Correspondingly, when the assembly hole 110 of the precast parapet 100 is made, the corresponding steel bar size should be at least 118 mm or 120 mm in diameter, so as to provide a relatively large space for assembling the connecting steel bar 210. When grouting the assembly hole 110, it can also ensure that the grout fully wraps the connecting steel bar 210, so that after the grout solidifies, the connecting steel bar 210 and the precast parapet 100 are fixed into a stable whole.

[0044] In one specific implementation, such as Figure 5 As shown, the cross-section of the aforementioned assembly hole 110 can be specifically set to be circular to facilitate fitting with the connecting steel bar 210 during installation, providing ample space for the connecting steel bar 210 in multiple directions for easy installation; in another possible embodiment, such as Figure 7 As shown, when the thickness of the precast parapet 100 is relatively thin, the cross-section of the above-mentioned assembly hole 110 can be set as an ellipse, and the major axis of the elliptical assembly hole 110 corresponds to the length direction of the precast parapet 100, thereby providing more spare space for the connecting steel bar 210 in the length direction of the precast parapet, so as to facilitate installation.

[0045] In other possible embodiments of this utility model, the above-mentioned assembly hole 110 can be formed by placing a corrugated sleeve inside the precast railing 100 during prefabrication. The inner side of the corrugated sleeve is a smooth through hole, and the outer side of the corrugated sleeve is provided with a wave-shaped concave-convex structure. When applied to the precast railing 100, it can form a firm fit with the concrete, thereby facilitating the production of the assembly hole 110 in the precast railing 100.

[0046] Based on the above embodiments, in another possible embodiment of this utility model, such as Figure 6As shown, to further improve the connection stability between the connecting steel bar 210 and the precast parapet 100 after grouting, a locking member 211 is also provided at the end of the connecting steel bar 210 in this embodiment. The locking member 211 is shaped like a hat, with a diameter slightly larger than that of the connecting steel bar 210. It is fitted onto the end of the connecting steel bar 210 and fixedly connected to it. The locking member 211 is installed after the connecting steel bar 210 is embedded in the installation platform 200 and before it is combined with the precast parapet 100. After the 10 is inserted into the assembly hole 110, the locking member 211 is located in the assembly hole 110. During grouting, the grout fills the locking member 211 and forms a wrap around it. Since the diameter of the locking member 211 is larger than the diameter of the connecting steel bar 210, the grout can lock the locking member 211 after it solidifies, thereby locking the connecting steel bar 210. This can effectively prevent the precast slab 100 from separating from the connecting steel bar 210 due to external forces, thus effectively improving the safety of the precast slab 100.

[0047] In another possible embodiment of this utility model, such as Figure 1 As shown, to prevent the precast parapet 100 from shaking at the joint after being installed on the installation platform 200, which would affect the fixing angle of the precast parapet 100 after grouting, a filling layer 300 is also provided on the installation platform 200 corresponding to the bottom surface of the precast parapet 100 in this embodiment. The filling layer 300 is made of concrete, and the aforementioned connecting steel bars 210 are provided through the filling layer 300. After the precast parapet 100 is combined with several connecting steel bars 210, the precast parapet 100 sits on the filling layer 300. The mortar in the filling layer 300 forms a level. After the filling layer 300 is cured, it can fix the bottom surface of the precast parapet 100 to the installation platform 200, and make the joint between the precast parapet 100 and the installation platform 200 more aesthetically pleasing.

[0048] In one specific embodiment, a pre-embedded sleeve can also be installed at the position corresponding to the above-mentioned installation platform 200. The pre-embedded sleeve is locked in the installation platform 200 during the curing process. After the pre-embedded sleeve is fixed in the installation platform 200, a connecting steel bar 210 with a matching thread is installed in the pre-embedded sleeve, thereby forming a connection structure with the same connecting steel bar 210 as above and the assembly hole 110 on the precast railing 100.

[0049] Furthermore, such as Figure 1As shown, to improve the waterproofing performance of the joint between the precast parapet 100 and the installation platform 200, in this embodiment, a waterproof component 310 is continuously provided on the outer side of the aforementioned filling layer 300. The waterproof component 310 is specifically a PE rod, etc. PE rod, or polyethylene rod, is a common plastic material with excellent wear resistance and corrosion resistance. It can resist the erosion of various chemicals and is suitable for various industrial environments. In addition, PE rod also has good impact resistance and a low coefficient of friction. When specifically installed, the height of the waterproof component 310 should be adapted to the height of the filling layer 300, and it can be filled with materials such as polyurethane sealant. This ensures that the waterproof component 310 is fixedly connected to the precast parapet 100 and the installation platform 200, while achieving a circumferential waterproofing effect through the waterproof component 310, preventing rainwater and other corrosive liquids from entering the interior along the joint between the precast parapet 100 and the installation platform 200 and affecting the service life of the precast parapet 100.

[0050] In another embodiment of this utility model, during the manufacturing of the precast slab 100, in order to give the precast slab 100 a better resistance to external forces, a frame 400 is also provided inside the precast slab 100. Specifically, as shown in... Figure 3 and Figure 4 As shown, the frame 400 includes longitudinal ribs 410, transverse ribs 420, and reinforcing ribs 430. The longitudinal ribs 410 are arranged vertically and can be formed by bending and combining one or more steel bars to form a ring. The shape of the longitudinal ribs 410 is adapted to the thickness and height of the precast slab 100, and several longitudinal ribs 410 are evenly arranged along the length of the precast slab 100. The transverse ribs 420 are also arranged vertically and can be formed by bending and combining one or more steel bars to form a ring. The shape of the transverse ribs 420 is adapted to the thickness and length of the precast slab 100, and several transverse ribs 420 are evenly arranged along the height of the precast slab 100. The reinforcing ribs 430 are also steel structures and are used to fix and connect with the longitudinal ribs 410 and transverse ribs 420 at predetermined positions, thereby forming a fixed integral structure of the frame 400, which facilitates the production of the precast slab 100 by concrete pouring.

[0051] Furthermore, to facilitate the accurate alignment and fixed connection of adjacent precast railings 100 during installation, in this embodiment, as follows: Figure 5As shown, extensions 120 are provided at both ends of the precast slab 100 along its length. The extensions 120 are structures that protrude towards both ends of the precast slab 100, and their thickness is less than that of the precast slab 100, thus forming a stepped structure. During installation, the extensions 120 of adjacent precast slabs 100 correspond, and the recessed structure formed on one side of the extension 120 can be filled by grouting. This results in smaller joints between adjacent precast slabs 100 and facilitates the calibration of the installation angles of adjacent precast slabs 100 by construction personnel. After the recessed structure on one side of the extension 120 is cured using a mold and grouting, a fixed connection between the joints of adjacent precast slabs 100 can be achieved, resulting in a more aesthetically pleasing and reliable installation.

[0052] Specifically, to make the recessed portion on one side of the extension 120 of the adjacent precast parapet 100 more secure during connection, in this embodiment, the frame 400 further includes several connecting ribs 440, such as... Figure 5 As shown, the main body of the connecting rib 440 is fixedly wrapped around the aforementioned longitudinal rib 410 to form a fixed connection. During the fabrication of the precast slab 100, it is cast into the interior of the precast slab 100 for further fixation. The end of the connecting rib 440 protrudes from one side of the extension 120, i.e., it is located in the groove on the side of the extension 120. When two adjacent precast slabs 100 are joined together, the corresponding extensions 120 are tightly aligned. A mold is set on the side of the precast slab 100 away from the extension 120, and the groove of the two adjacent precast slabs 100 is cast. The end of the connecting rib 440 can be cast into the connection part to form a connection part with a skeleton structure 400. Since the end of the connecting rib 440 is bent, it can form a hook with the inside of the casting module, thereby playing a fixed connection role and effectively ensuring the stability of the connection between adjacent precast slabs 100.

[0053] In the above embodiments, such as Figure 5 As shown, since the thickness of the extension 120 is smaller than that of the precast slab 100, its structure is relatively thin and is easily damaged by accidental bumps during the transportation of the precast slab 100. To avoid damage to the extension 120, in this embodiment, the ends of the transverse ribs 420 are also correspondingly arranged in the extension 120, so that the extension 120 has a frame 400 structure that is integrated with the main body of the precast slab 100, which can ensure that the extension 120 is structurally reliable and reduce the probability of damage caused by bumps during transportation and hoisting.

[0054] In the above embodiments, the longitudinal ribs 410, transverse ribs 420 and connecting ribs 440 are all steel bars, and their functions are the same as those of adding steel bars to concrete structures in the prior art, all of which improve the load-bearing capacity and enhance the structural stability, thereby improving the mechanical properties.

[0055] In some other possible implementations, the longitudinal ribs 410, transverse ribs 420, reinforcing ribs 430, and connecting ribs 440 can be made of steel plates in addition to being rolled from the aforementioned steel bars, in order to achieve the same effect of improving load-bearing performance. When steel plates are used, different components in relative positions can be connected and fixed by welding, and then concrete is used on the outside to form a complete precast parapet 100. In addition, the longitudinal ribs 410, transverse ribs 420, reinforcing ribs 430, and connecting ribs 440 can also be made of other materials with better load-bearing performance and shear resistance. This application does not limit this, and those skilled in the art can make the settings according to actual needs.

[0056] Based on the above embodiments, the actual installation process of the connection structure of the precast concrete parapet of this utility model is as follows:

[0057] like Figure 1 As shown, during the construction of the installation platform 200, several connecting steel bars 210 are pre-embedded at predetermined locations. One end of each connecting steel bar 210 protrudes from the installation platform 200. After the installation platform 200 is completed, the connecting steel bars 210 are vertically installed, as shown in the diagram. Figure 6 As shown, a locking piece 211 is installed at the end of the connecting steel bar 210;

[0058] A concrete filling layer 300 is constructed at the location where the precast parapet 100 is to be installed. Waterproofing components 310 are then arranged around the perimeter of the filling layer 300. Figure 1 As shown, several assembly holes 110 of the precast parapet 100 are fitted one-to-one with several connecting steel bars 210 to form a structure as shown in the figure. Figure 6 As shown in the structural design, the bottom surface of the precast parapet 100 rests on the filling layer 300 and the waterproof component 310. After it is placed stably and at a suitable angle, grout is injected into several assembly holes 110. Once the grout has cured, the precast parapet 100 is installed and fixed. At this time, sealant is used to fill the outside of the waterproof component 310 to prevent water, corrosive liquids, etc. from flowing into the joint between the precast parapet 100 and the installation platform 200.

[0059] When installing adjacent precast parapets 100, since the diameter of the assembly hole 110 is much larger than the diameter of the connecting steel bar 210, there is a large adjustment space to make the adjacent precast parapets 100 correspond. Specifically, the extensions 120 of the adjacent precast parapets 100 are aligned, and a mold is set to grout the groove on one side of the extension 120. The grout wraps around the end of the connecting steel bar 440. After curing, the fixed connection of the adjacent precast parapets 100 is achieved.

[0060] In summary, this utility model provides a connection structure for a precast concrete parapet. This connection structure includes: a precast parapet with several assembly holes penetrating its upper and lower surfaces; and an installation platform with several connecting reinforcing bars embedded within it, one end of each connecting reinforcing bar protruding from the platform. The positions of the connecting reinforcing bars correspond one-to-one with the center points of the assembly holes. This utility model, by providing assembly holes penetrating the upper and lower surfaces of the precast parapet and embedding corresponding connecting reinforcing bars on the installation platform, allows for greater tolerance compared to traditional grouting sleeve connection methods. It also provides adjustment margins for connecting adjacent precast parapets, reduces the precision requirements for the embedded connecting reinforcing bars, minimizes rework, and improves construction smoothness.

[0061] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
