Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a prefabricated concrete beam-column joint installation construction structure. Background Technology

[0002] In prefabricated concrete structure construction, the mainstream method for beam-column joints in China is currently to use cast-in-place concrete. However, various issues arise during cast-in-place concrete construction that can affect structural strength. For example, improper pouring control can lead to uneven thickness of the cast-in-place strip. Inadequate pouring and curing processes may cause stresses generated during hardening due to temperature changes and shrinkage to exceed material strength limits, resulting in the risk of cracking after pouring. Improper cast-in-place construction can also lead to pitting and voids on the poured surface, requiring repair work.

[0003] Post-cast concrete construction involves long wet-work periods, and its quality is significantly affected by human factors. Therefore, there is an urgent need for a rapid construction technique in prefabricated concrete structure construction that can simplify the process and increase assembly speed.

[0004] Currently, to reduce post-pouring construction steps, a structure for cast-in-place reinforced concrete frame beam-column joints, as disclosed in CN201621250354.2, can be adopted. This involves setting a circular enlarged head in the joint area, with circumferential stirrups and vertical tie bars inside the enlarged head, and appropriately widening the spacing between the longitudinal reinforcement bars of the beam. This allows concrete to quickly enter the core area of ​​the joint, completing the pouring in one go, thereby reducing construction steps and lowering construction difficulty. However, while this structural design reduces the difficulty of post-pouring construction through the setting of circumferential stirrups and vertical tie bars, it still requires post-pouring concrete construction operations.

[0005] CN202110429307.3 discloses a self-tethered steel-wood composite node and its installation method. The self-tethered steel-wood composite node includes self-tethered composite columns, composite beams, and beam-column reinforcement kits. Beam-column nodes are formed by connecting peripheral tie columns in pairs and by connecting the central tie column to the peripheral tie columns. This self-tethered node structure can improve the overall integrity of the component to a certain extent. However, the mortise and tenon joint between the central column and the peripheral tie columns results in a complex structure and inconvenience in assembly. Although it simplifies the post-pouring process, the numerous initial connection steps do not achieve the desired simplification of the process and improvement of assembly speed. Utility Model Content

[0006] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the existing technology, this utility model provides a prefabricated concrete structure beam-column joint installation construction structure. When the upper and lower concrete columns are connected, steel tie members are used to surround them, and a concrete beam is designed between two adjacent steel tie members. This can effectively complete the connection of the concrete structure beam-column joint, effectively simplify the assembly process, improve the assembly speed, and at the same time, the construction quality is high, the integrity is strong, and the beam-column joint has better integration.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a prefabricated concrete beam-column joint installation construction structure, including an upper concrete column, a lower concrete column, several steel tie members, and a concrete beam with the same number of steel tie members. Several installation holes are respectively opened on the outer circumferential surface of the connection end between the upper and lower concrete columns. The steel tie members form a ring structure, and the outer circumferential surface of the connection end between the upper and lower concrete columns is adapted to the inner wall of the ring structure. Tie holes that match the holes on the concrete columns are opened on the ring structure. The ring structure and the corresponding upper and lower concrete columns are positioned and fixed through the tie holes and installation holes. A slot is provided at the connection end of two adjacent steel tie members. The slot is adapted to the shape of the concrete beam end, and the concrete beam end is inserted into the slot, and the concrete beam end is respectively positioned and fixed with two steel tie members.

[0008] In the above scheme, after the steel tie members are enclosed and fixed to the concrete column, they not only form a stable enclosed structure relative to the concrete column, but also form a slot for the concrete beam to be connected during the enclosed process. The concrete beam is fixed to the slot, thereby forming a prefabricated concrete structure beam-column joint connection. The positioning is quick, the process is simple, the assembly process is convenient and fast, and the beam-column joint has good integrity.

[0009] Furthermore, the outer circumferential surface of the connection end between the upper and lower concrete columns is recessed to provide a groove for the steel tie rod to mate with. The outer groove surface of the groove is connected to the connection end surface of the corresponding concrete column, and the mounting holes are distributed on the bottom of the groove. This groove design provides installation space for the steel tie rod to mate with, directly providing a position for enclosure and positioning, making positioning more convenient and reliable, and improving assembly efficiency.

[0010] Furthermore, in the upper and lower concrete columns, the mounting holes on adjacent sides of the same concrete column are staggered vertically. This staggered arrangement of mounting holes provides space for driving in positioning bolts during installation, preventing interference between bolts driven in from adjacent sides. It also provides a better and more stable connection and assembly for the concrete beams in a fixed configuration.

[0011] Furthermore, in the upper and lower concrete columns assembled to form the same beam and column, the installation holes on the same side of the upper and lower concrete columns are distributed in a mirror image along the connecting end face of the concrete columns.

[0012] Preferably, the upper and lower concrete columns are quadrangular prisms, and the number of steel tie members is four, which are arranged in an L-shaped structure corresponding to the corners of the quadrangular prisms.

[0013] Furthermore, the steel tie member includes an upper plate, a lower plate, and a side plate. The upper and lower plates have an L-shaped radial cross-section and are arranged parallel to each other. The side plate connects the inner edges of the upper and lower plates. Vertical plates are also provided on the inner sides of the L-shaped ends of the upper and lower plates of the steel tie member. The two vertical plates corresponding to the connecting ends of two adjacent steel tie members, together with the upper and lower plates, form a slot for the concrete beam to be inserted and fitted.

[0014] Furthermore, the upper and lower plates of the steel tie member are respectively provided with fixing holes at the positions where the slots are formed, and the ends of the concrete beams are respectively provided with beam end holes. After the concrete beams are inserted into the slots, the beam end holes correspond to the fixing holes and are fixed by fixing bolts.

[0015] The beneficial effects of this utility model are as follows: The prefabricated concrete beam-column joint installation structure provided by this utility model has a reasonable structural design. Holes are opened on the outer circumferential surfaces of the joint ends of the upper and lower concrete columns. Steel tie members are installed by enclosing the upper and lower concrete columns through these holes. Adjacent steel tie members close at their connecting end faces to form slots for the insertion and mating of concrete beams. After the concrete beams are inserted into these slots, they lock with the corresponding two steel tie members, thus completing the construction and installation of the entire beam-column joint. The installation process is convenient and quick, the technology is simple, and the assembly rate is high. Furthermore, the assembled beam-column joint has good overall integrity, and the structure is more stable and reliable. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0032] like Figures 1 to 12The prefabricated concrete beam-column joint installation construction structure shown is the preferred embodiment of this utility model. This installation construction structure includes an upper concrete column 1, a lower concrete column 21, several steel tie members 3, and a number of concrete beams 4 equal to the number of steel tie members 3.

[0033] In this embodiment, the upper concrete column 1 and the lower concrete column 21 are square prisms. Correspondingly, there are four steel tie rods 3 and four concrete beams 4.

[0034] like Figure 2 , Figure 3 , Figure 4 As shown, in the actual design, to facilitate the positioning of the steel tie member 3, the outer circumferential surface of the corresponding connection end of the upper concrete column 1 and the lower concrete column 21 is recessed to form a groove 5 for the steel tie member 3 to fit into. The outer groove surface of the groove 5 is connected to the connection end face of the corresponding concrete column. Several installation holes 6 are provided on the bottom of the groove 5, and the steel tie member 3 is provided with tie holes 7 that match the holes on the concrete column. In the upper concrete column 1 and the lower concrete column 21, the installation holes 6 on adjacent sides of the same concrete column are staggered vertically. In the upper concrete column 1 and the lower concrete column 21 assembled to form the same beam-column structure, the installation holes 6 on the same side of the upper concrete column 1 and the lower concrete column 21 are distributed in a mirror image along the connection end face of the concrete column. Therefore, in the actual production of concrete columns, the upper concrete column 1 and the lower concrete column 2 can be produced as the same type of concrete column. After adjusting the rib surface during installation, the concrete columns are flipped up and down to form the relative upper concrete column 1 and lower concrete column 2.

[0035] Thus, when the steel tie member 3 is assembled and fixed to the concrete column, the fixing installation is performed by driving positioning bolts 8 into the corresponding installation holes 6 and tie holes 7. The vertically staggered distribution of the installation holes 6 provides installation space for driving in the positioning bolts 8, avoiding interference between positioning bolts 8 driven into adjacent sides, and also provides a better and more stable connection and assembly for the concrete beam 4 in the fixed position. Nuts and washers can be added as needed when driving in the positioning bolts 8, which will not be elaborated here.

[0036] Specifically, the structure of the steel tie member 3 corresponds to the corner of the quadrangular prism and adopts an L-shaped structure. The four steel tie members 3 enclose the grooves 5 of the upper concrete column 1 and the lower concrete column 21 to form a ring structure.

[0037] like Figure 5 and Figure 6As shown, each steel tie member 3 includes an upper plate 9, a lower plate 10, and a side plate 11. The upper plate 9 and the lower plate 10 have an L-shaped flat plate structure in radial cross section, and the upper plate 9 and the lower plate 10 are arranged parallel to each other vertically. The upper plate 9 abuts against the upper side of the groove 5 of the upper concrete column 1, and the lower plate 10 abuts against the lower side of the groove 5 of the lower concrete column 2. The side plate 11 connects the inner edges of the upper plate 9 and the lower plate 10, and the inner surface of the side plate 11 abuts against the groove 5 of the upper and lower concrete columns, thereby using positioning bolts 8 to connect and fix the steel tie member 3 to the concrete column.

[0038] Each steel tie member 3 has vertical plates 12 supporting the inner sides of its L-shaped ends, including the upper plate 9 and lower plate 10. The two vertical plates 12 at the connecting ends of adjacent steel tie members 3, together with the upper plate 9 and lower plate 10, form a slot for the insertion of a concrete beam 4. The upper plate 9 and lower plate 10 of the steel tie member 3 have corresponding fixing holes 13 at the positions of the slots, and the ends of the concrete beam 4 have corresponding vertical beam end holes 14. After the concrete beam 4 is inserted into the slot, the beam end holes 14 align with the fixing holes 13 and are secured by fixing bolts 15. A fixing bolt 15 must pass through the fixing holes 13 on the upper plate 9 of the steel tie member 3, the beam end holes 14 of the concrete beam 4, and the fixing holes 13 on the lower plate 10 of the steel tie member 3 from top to bottom, and is then secured to the steel tie member 3 and the concrete beam 4 using a nut. Since a concrete beam 4 is fixed at its ends to the fixing holes 13 of two steel tie members 3, this assembly process not only forms a beam-column joint, but also provides a further tie-fixing effect for the connection between the two steel tie members 3.

[0039] During installation, first connect the upper concrete beam 4 and the lower concrete beam 4 according to the corresponding positions of the installation holes 6. Figure 4 This aligns the upper and lower grooves 5, forming an annular groove for the steel tie member 3 to be fully embedded and fitted. The steel tie member 3 then surrounds ( Figure 7 and Figure 9 The concrete column joint is wrapped from four directions, and mates with the annular groove of the concrete column. Positioning bolts 8 are driven into the installation holes 6 and tie holes 7 for fixation. Figure 10 and Figure 11 This ensures the steel tie member 3 is securely positioned against the concrete column. At this point, the steel tie member 3, when closed, also forms a slot for the concrete beam 4 to connect with it. The concrete beam 4 is then inserted into the corresponding slot. Figure 12 ), and use fixing bolts 15 to fix the slot to the concrete beam 4 ( ), and use fixing bolts 15 to fix ( Figure 13 This forms the beam-column joint connection of prefabricated concrete structure. Figure 1 ).

[0040] In actual production, the steel tie rods 3, concrete columns, and concrete beams 4 can all be prefabricated in the factory and transported to the construction site for assembly to form a safe, reliable, and effective beam-column joint. This beam-column joint is easy and quick to install, with precise and reliable positioning, simple construction techniques, and a high assembly rate. No post-pouring process is required during assembly, and the assembled beam-column joint has better overall integrity and a more stable and reliable structure.

[0041] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
