Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, and in particular to a multifunctional deformation joint energy dissipation device and a construction method. BACKGROUND

[0002] Building bodies are prone to deformation under the action of external factors such as temperature environment, foundation settlement, earthquake action, etc., resulting in cracking or damage, affecting the durability, safety and applicability of the building structure. In order to improve the reliability of the building, especially in long buildings or buildings with large height difference, a special construction measure, deformation joint, is often used. Deformation joints include expansion joints, settlement joints and anti-seismic joints. Many buildings prefer to consider expansion joints, anti-seismic joints and settlement joints comprehensively and set them at the same position. By reasonably setting the deformation joint, not only can the cracking and even structural damage of the building due to stress caused by external factors be effectively avoided, but also the overall stability of the building can be enhanced, and the service life of the building can be prolonged, and the safety of the occupants' life and property can be ensured.

[0003] Traditional house building deformation joint protection devices are usually made of stainless steel and are directly clamped into the deformation joint, and a stainless steel plate is used to realize the dustproof function. This structure has relatively poor stability. When the house is deformed due to temperature changes or earthquakes and other factors, the protection device may be deformed or even fall off due to extrusion. Another fixing method is to use bolts to fasten the protection structure on the wall. Although this method is more stable, when the house deforms, the bolts and the protection structure may hinder the natural movement of the structure, thereby causing damage to the wall. Therefore, the traditional deformation joint protection device still needs to be improved. SUMMARY

Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0053] With reference to Figure 1 and Figure 2 , the present application discloses a multifunctional deformed joint 11 energy dissipation device, which comprises a protection unit 2, an energy dissipation unit 3, a waterstop 4 and a fireproof unit 5 arranged in the deformed joint 11. The deformed joint 11 to which the energy dissipation device of the present application is applicable has a width of not less than 100 mm, and the concrete member 12 to which the energy dissipation device of the present application is applicable has a thickness of not less than 150 mm.

[0054] The protection unit 2 comprises:

[0055] two right-angle steel plates 21, which are respectively fixed to the joint walls on both sides of the deformed joint 11, specifically, the vertical sections of the right-angle steel plates 21 are attached to the joint walls of the deformed joint 11, and the horizontal sections are attached to the surface of the concrete member 12; and

[0056] The flat steel plate 22 is hinged between the two right-angle steel plates 21 and covers the gap between the two right-angle steel plates 21, and the right-angle steel plates 21 and the flat steel plate 22 are both made of stainless steel plates, and in one arrangement example, the horizontal section of the right-angle steel plate 21 has a width of 100 mm, and the vertical section has a height of not less than 120 mm.

[0057] wherein, with reference to Figure 2 and Figure 3 the energy dissipation unit 3 comprises:

[0058] the energy dissipation element 31 is provided with an even number of energy dissipation elements 31 on the cross section of the deformation joint 11 and is fixed to the corresponding side wall of the two right-angle steel plates 21 respectively, and the two oppositely arranged energy dissipation elements 31 form an energy dissipation group, and specifically, two energy dissipation groups are arranged on the same cross section of the deformation joint 11, and the two energy dissipation groups are arranged uniformly on the vertical section of the right-angle steel plate 21;

[0059] the outer pipe 32 is hinged to one of the energy dissipation elements 31 in one energy dissipation group at one end;

[0060] the inner rod 33 is hinged to the other energy dissipation element 31 in one energy dissipation group at one end and is arranged in the corresponding outer pipe 32 at the other end, and specifically, the outer pipe 32 and the inner rod 33 are both made of steel pipes; and

[0061] the energy dissipation spring 34 is sleeved on the outer rod 33 and is abutted against the corresponding outer pipe 32 at one end and the other end of the inner rod 33 away from the outer pipe 32.

[0062] Specifically, the energy dissipation element 31 comprises:

[0063] the rectangular frame 311 is made of steel;

[0064] the hinge support 312 is arranged in the middle of the rectangular frame 311, and the ends of the outer pipe 32 and the inner rod 33 away from each other are hinged to the corresponding hinge supports 312 respectively;

[0065] the transverse spring 313 is provided with four transverse springs 313 and is arranged between the four side walls of the hinge support 312 and the corresponding four inner side walls of the rectangular frame 311, and one end of the transverse spring 313 is fixed to the side wall of the hinge support 312 and the other end is fixed to the inner wall of the rectangular frame 311.

[0066] Furthermore, the hinge shafts of the outer pipe 32 and the inner rod 33 on the energy dissipation element 31 and the hinge shafts of the flat steel plate 22 on the right-angle steel plate 21 are arranged along the extension direction of the deformation joint 11.

[0067] Thus, through the design of the four horizontal displacement springs 313 between the hinge support 312 and the rectangular frame 311 in the energy dissipation element 31, the hinge support 312 has a multidirectional buffering effect in the horizontal plane on the rectangular frame 311, and the outer pipe 32 and the inner rod 33 connected thereto are more flexible to adapt to the settlement and deformation of the deformation joint 11, so as to ensure that they can maintain stability and safety under multidirectional stress conditions, so that the components are not easily damaged. Moreover, with the arrangement of the energy dissipation spring 34 between the two energy dissipation elements 31 in the same energy dissipation group, the energy dissipation spring 34 can further dissipate the horizontal and vertical external forces and absorb and consume part of the energy, thereby reducing the stress concentration on the components and reducing the risk of damage. In this way, not only the overall stability and durability of the building structure can be improved, but also the service life of the components can be significantly prolonged.

[0068] Further, referring to Figure 1 and Figure 4 , two flat steel plates 22 are arranged, and the two flat steel plates 22 are hingedly connected to each other, and the side edges of the two flat steel plates 22 away from each other are hingedly connected to the two straight steel plates 21, specifically, the hinge parts are hingedly connected by cylindrical pin bolts 25; the vertical section of the straight steel plate 21 is attached to the wall of the deformation joint 11, and the horizontal section is provided with a rubber pad 23 between the surface of the concrete component 12 corresponding to the deformation joint 11, and the horizontal section of the straight steel plate 21 is provided with an expansion bolt 24 penetrating the rubber pad 23 and fixed in the concrete component 12.

[0069] Thus, by the design of the protection unit 2, the traditional deformation joint 11 protection plate is replaced, so that the protection unit 2 of the present application has the hinge design of four stainless steel plates and three cylindrical pin bolts 25, which can adapt to the deformation and settlement of the building to a great extent, and solves the problem that the node structure in the prior art cannot adapt to the expansion and deformation of the deformation joint 11 and the angle adjustment. At the same time, the protection unit 2 can maintain normal protection function and also maintain the appearance of the surface of the deformation joint 11.

[0070] In addition, referring to Figure 1 and Figure 5 , the waterstop 4 is embedded in the concrete components 12 on both sides of the deformation joint 11, the waterstop 4 is located on the side of the energy dissipation unit 3 away from the protection unit 2, and the waterstop 4 is a middle-buried middle-hole type rubber waterstop. The waterstop 4 is embedded in the concrete component 12 below the energy dissipation unit 3, which can play a role in preventing water from seeping into the structure.

[0071] Referring to Figure 1 and Figure 6 , the fireproof unit 5 comprises:

[0072] The supporting plate 51 is located on the side of the water stop belt 4 away from the energy dissipation unit 3, and the supporting plate 51 is integrally formed with a clamping edge 511 with an anti-skid structure near the side edge of the joint wall of the deformation joint 11. The clamping edge 511 can be provided with an anti-skid structure on the outer side edge, or can be wavy or serrated in shape.

[0073] The fireproof blocking layer 52 is filled between the supporting plate 51 and the water stop belt 4. Specifically, the supporting plate 51 is made of steel material, and the filling thickness of the fireproof blocking layer 52 is not less than 20 mm.

[0074] Therefore, the fireproof unit 5 is added to the traditional deformation joint 11 device, the supporting plate 51 of the fireproof unit 5 has a certain deformation ability, and the clamping edges 511 on both sides of the supporting plate 51 are designed to utilize the friction force to ensure that the fireproof blocking layer 52 can be stably fixed when filled in the supporting plate 51, so as not to fall or shift from the deformation joint 11. This design effectively improves the stability of the fireproof blocking layer 52, and ensures that it can reliably play a fireproof role in various environments.

[0075] The embodiment of the application also discloses a multifunctional deformation joint 11 energy dissipation device construction method based on the multifunctional deformation joint 11 energy dissipation device.

[0076] The multifunctional deformation joint 11 energy dissipation device construction method comprises the following steps.

[0077] S1. Laying the water stop belt 4: before pouring the concrete member 12 on both sides of the deformation joint 11, the water stop belt 4 is laid below the concrete member 12, and the distance between the water stop belt 4 and the bottom of the concrete member 12 is about 20-40 mm;

[0078] S2. Pouring concrete: reserving the position of the deformation joint 11, and pouring the concrete member 12 according to the determined elevation;

[0079] S3. Connecting the protection unit 2 and the energy dissipation unit 3: the protection unit 2 and the energy dissipation unit 3 are fixed by the energy dissipation elements 31 and the vertical sections of the straight angle steel plates 21 on both sides, so that the protection unit 2 and the energy dissipation unit 3 are stably connected; a plurality of energy dissipation elements 31 on each side are arranged vertically on the vertical section of the straight angle steel plate 21;

[0080] S4. Placing the connected protection unit 2 and energy dissipation unit 3 into the deformation joint 11: after the concrete member 12 reaches the design strength and the surface of the member is cleaned of sundries, the connected protection unit 2 and energy dissipation unit 3 are placed into the deformation joint 11, and the rubber pad 23 is placed between the horizontal section of the straight angle steel plate 21 and the concrete member 12;

[0081] S5. Installing expansion bolts 24: install expansion bolts 24 on the horizontal section of the angle steel plate 21 to fix the connected protection unit 2 and energy dissipation unit 3 on the concrete member 12;

[0082] S6. Installing fireproof unit 5: fill the fireproof sealing layer 52 into the supporting plate 51, and insert the supporting plate 51 and the fireproof sealing layer 52 from below the water stop 4 between the two concrete members 12, with the bottom plate of the supporting plate 51 down. If necessary, use structural glue to fix the supporting plate 51.

[0083] Therefore, the energy dissipation device after being applied can optimize the anti-deformation, anti-seismic and anti-expansion performance of the deformation joint 11 of the building, and has additional functions of energy dissipation, waterproofing and fireproofing, and integrates multiple functions. When the building is subjected to external force, the device can absorb and consume part of the energy through the internal structure, reduce the impact received by the building, and solve the problem that the node structure in the prior art cannot adapt to the expansion and deformation of the deformation joint 11 and the angle adjustment, so as to ensure that the adjacent structural components are not in direct contact or collision. Moreover, the device also has waterproofing and fireproofing functions, improves the safety and durability of the building, and optimizes the maintenance work of the deformation joint 11.

[0084] The implementation principle of the multifunctional deformation joint 11 energy dissipation device in the embodiment of the application is as follows:

[0085] Through the design of the four horizontal displacement springs 313 between the hinge supports 312 and the rectangular frames 311 in the energy dissipation elements 31, the hinge supports 312 can have multidirectional buffering effect in the horizontal plane of the rectangular frames 311, so that the outer pipes 32 and inner rods 33 hingedly connected thereto can more flexibly adapt to the settlement and deformation of the deformation joint 11, so as to ensure that they can maintain stability and safety under multidirectional stress conditions, so that the components are not easily damaged. Moreover, with the arrangement of the energy dissipation springs 34 between the two energy dissipation elements 31 in the same energy dissipation group, the energy dissipation effect on horizontal and vertical external force impact in multiple directions can be further achieved, so that part of the energy can be absorbed and consumed, thereby reducing the stress concentration on the components and reducing the risk of damage. In this way, not only the overall stability and durability of the building structure can be improved, but also the service life of the components can be significantly prolonged.

[0086] Moreover, through the design of the protection unit 2, the traditional deformation joint 11 protection plate is replaced, so that the protection unit 2 of the application has the hinge design of four stainless steel plates and three hinge parts, which can adapt to the deformation and settlement of the building to a great extent, and solve the problem that the node structure in the prior art cannot adapt to the expansion and deformation of the deformation joint 11 and the angle adjustment. At the same time, the protection unit 2 can maintain normal protection function and also maintain the appearance of the surface of the deformation joint 11.

[0087] It should be pointed out finally that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit the same; and although the present application has been described in detail with reference to the foregoing embodiments, it should be appreciated by those skilled in the art that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features thereof can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
