Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a fully prefabricated corrugated shell beam-column joint system. Background Technology

[0002] Currently, in building construction projects, the traditional construction method for beam-column joints is to tie the steel reinforcement cages of the beams and columns separately, then set up the formwork for the beams and columns, then pour the concrete for the beams and columns, and finally remove the formwork. However, it is difficult to connect the steel reinforcement at the joints when tying the steel reinforcement cages of the beams and columns, and the formwork setting and removal require a lot of time and result in low construction efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fully prefabricated corrugated shell beam-column joint system. After the shell columns and shell beams are hoisted and connected to the core steel body, concrete is directly poured into the shell columns and shell beams, avoiding the processes of rebar tying and formwork erection and dismantling, thus improving construction efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is a fully prefabricated corrugated shell beam-column joint system, comprising:

[0005] The core steel body is detachably connected to the top of the existing structural column;

[0006] The shell column is vertically arranged and is detachably connected to the top of the core steel body. The shell column has a first space for concrete pouring.

[0007] A shell beam is arranged horizontally, one end of which is detachably connected to the opposite outer side of the core steel body, and a second space for concrete pouring is provided inside the shell beam.

[0008] A further improvement of this fully assembled corrugated shell beam-column joint system is that the core steel body includes two horizontal plates spaced apart vertically and two vertical plates connected in parallel between the two horizontal plates. The lower horizontal plate is connected to the existing structural column by a first bolt.

[0009] A further improvement of this fully assembled corrugated shell beam-column joint system is that the shell column comprises:

[0010] At least three pipe fittings are arranged in parallel intervals, and at least three of the pipe fittings are not on the same plane;

[0011] Corrugated plates are fitted around the outer periphery of at least three of the pipe fittings;

[0012] A first sealing plate is connected to the bottom of at least three of the pipe fittings and the corrugated plate, and the first sealing plate and the corrugated plate together enclose the first space.

[0013] A further improvement of this fully assembled corrugated shell beam-column joint system is that the shell column also includes multiple reinforcing rods, and multiple reinforcing rods are vertically spaced between each pair of adjacent or opposite pipe components.

[0014] A further improvement of this fully assembled corrugated shell beam-column joint system is that the shell column is connected to the core steel body by a second bolt. One end of the second bolt is connected to the pipe fitting, and the other end extends out of the first bottom plate to form an extension section. A first connecting hole is provided on the horizontal plate above for the extension section to pass through and connect.

[0015] A further improvement of this fully assembled corrugated shell beam-column joint system is that the shell beam comprises:

[0016] Two corrugated side webs are arranged vertically, and the two corrugated side webs are spaced apart in the horizontal direction;

[0017] Two corrugated end webs are arranged vertically, and the two corrugated end webs are spaced apart in the horizontal direction and are respectively connected to and sealed at both ends of the two corrugated side webs;

[0018] The second sealing plate connects to and seals the bottom of the two corrugated side webs and the two corrugated end webs. The two corrugated side webs, the two corrugated end webs, and the second sealing plate together form the second space.

[0019] Multiple tie plates are connected at intervals along the axial direction of the shell beam to the top of the two corrugated side webs.

[0020] A further improvement of this fully assembled corrugated shell beam-column joint system is that the shell beam further includes prestressed tendons, the two ends of which are respectively connected to the two corrugated end webs.

[0021] A further improvement of this fully assembled corrugated shell beam-column joint system is that the shell beam and the core steel body are connected by multiple angle steels, one side flange of each angle steel is connected to the corrugated side web or the second bottom sealing plate, and the other side flange is connected to the corresponding vertical plate.

[0022] Compared with the prior art, the advantages of this utility model are:

[0023] By setting up shell columns and shell beams and hoisting them to the core steel structure, the process of binding the beam and column steel cages and setting and dismantling formwork was avoided, thus improving construction efficiency. Attached Figure Description

[0032] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0033] The fully assembled corrugated shell beam-column joint system of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Please see Figures 1-6 The fully prefabricated corrugated shell beam-column joint system includes:

[0035] Core steel body 2, which is detachably connected to the top of the existing structural column 1;

[0036] A vertically arranged shell column 4 is detachably connected to the top of the core steel body 2, and a first space for concrete pouring is opened inside the shell column 4.

[0037] A shell beam 5 is arranged horizontally, one end of which is detachably connected to the opposite outer side of the core steel body 2. A second space for concrete pouring is provided inside the shell beam 5.

[0038] By setting up shell columns 4 and shell beams 5 and hoisting them to the core steel body 2, the process of binding the beam and column steel cages and setting and dismantling the formwork was avoided, thus improving construction efficiency.

[0039] Preferably, the core steel body 2 includes two horizontal plates 201 spaced apart vertically and two vertical plates 202 connected in parallel between the two horizontal plates 201. The lower horizontal plate 201 is connected to the existing structural column 1 by a first bolt 3.

[0040] Specifically, the first bolt 3 is pre-embedded at the top of the existing structural column 1, and a second connecting hole is provided on the horizontal plate 201 below for the first bolt 3 to pass through and connect.

[0041] Specifically, the core steel body 2 also includes a stiffening plate 203, which is connected between the two vertical plates 202.

[0042] By setting the stiffening plate 203, the stability of the core steel body 2 is improved.

[0043] Preferably, the shell pillar 4 includes:

[0044] At least three pipe fittings 401 are arranged in parallel intervals, and at least three of the pipe fittings 401 are not on the same plane;

[0045] Corrugated plate 402 surrounds the outer periphery of at least three of the pipe fittings 401;

[0046] The first sealing plate is connected to the bottom of at least three of the pipe fittings 401 and the corrugated plate 402, and the first sealing plate and the corrugated plate 402 together enclose the first space.

[0047] By setting up this shell column 4, there is no need for formwork support and dismantling; concrete can be poured only after the shell column 4 is hoisted into place.

[0048] Specifically, the shell column 4 also includes a steel reinforcement cage located within the first space and resting on the first sealing plate.

[0049] By installing this steel cage, the strength of the shell column 4 is increased after the concrete is poured inside the shell column 4.

[0050] Preferably, the shell column 4 also includes a plurality of reinforcing rods 403, with a plurality of reinforcing rods 403 vertically spaced between each adjacent or opposite pair of the tubes 401.

[0051] By setting the reinforcing rod 403, at least two of the pipe fittings 401 are connected to form a whole, which improves the structural stability.

[0052] Specifically, such as Figure 4 As shown: When the shell column 4 is a square column, there are four pipe fittings 401 arranged in a square. Multiple reinforcing rods 403 are spaced apart along the axial direction of the shell column 4, and two adjacent reinforcing rods 403 intersect each other. The two ends of the reinforcing rods 403 are respectively connected to the two pipe fittings 401 at opposite corners.

[0053] Preferably, the shell column 4 is connected to the core steel body 2 by a second bolt 8. One end of the second bolt 8 is connected to the pipe 401, and the other end extends out of the first sealing plate and forms an extension section. A first connecting hole is provided on the horizontal plate 201 above for the extension section to pass through and connect.

[0054] By setting the second bolt 8, the shell column 4 is mechanically connected to the core steel body 2, which improves the connection effect. In addition, after the concrete of the shell column 4 is poured, the second bolt is anchored in the concrete of the shell column 4, which further improves the connection stability of the shell column 4.

[0055] Preferably, the shell beam 5 includes:

[0056] Two corrugated side webs 501 are arranged vertically, and the two corrugated side webs 501 are spaced apart in the horizontal direction;

[0057] Two vertically arranged corrugated end webs are arranged at intervals in the horizontal direction and are respectively connected to and sealed at both ends of the two corrugated side webs 501.

[0058] The second sealing plate 502 connects to and seals the bottom of the two corrugated side webs 501 and the two corrugated end webs. The two corrugated side webs 501, the two corrugated end webs and the second sealing plate 502 together form the second space.

[0059] Multiple tie plates 504 are spaced apart along the axial direction of the shell beam 5 and connected to the top of the two corrugated side webs 501.

[0060] By setting multiple tie plates 504, the stability of the shell beam 5 is improved, and the two corrugated side webs 501 are prevented from shifting outward relative to each other during concrete pouring.

[0061] Specifically, the top of the two corrugated side webs 501 are also connected by two connecting plates 503 along their length, and the connecting plate 504 is connected between the two connecting plates 503.

[0062] By setting the connecting plate 503, a connection base is provided for the tie plate 504, avoiding the tie plate 504 from being directly connected to the two corrugated side web plates 501.

[0063] Specifically, shear-resistant key 505 is also connected to the two connecting plates 503. When the floor slab 6 is subsequently cast, the shear-resistant key is embedded in the floor slab 6.

[0064] Preferably, the shell beam 5 also includes prestressed tendons 506, the two ends of which are respectively connected to the two corrugated end webs.

[0065] By setting the prestressed tendon 506, the two corrugated end webs always have a relative inward axial force, which improves the stability of the shell beam 5 and also improves the shear resistance of the shell beam 5.

[0066] Specifically, multiple bottom reinforcing bars 507 are also interspersed between the two corrugated end webs.

[0067] By setting multiple bottom reinforcing bars 507 in the beam, the strength of the shell beam 5 is increased after the concrete is poured inside the shell beam 5.

[0068] Preferably, the shell beam 5 and the core steel body 2 are connected by a plurality of angle steels 7, one side flange of each angle steel 7 is connected to the corrugated side web plate 501 or the second bottom sealing plate 502, and the other side flange is connected to the corresponding vertical plate 202.

[0069] By setting multiple angle steels 7, the shell beam 5 is mechanically connected to the core steel body 2, thereby improving the connection effect.
