Description

Technical Field

[0001] This utility model belongs to the field of building structure technology, specifically, it relates to a construction structure for a large-span seismic isolation joint cover plate. Background Technology

[0002] During the construction process, for multi-story masonry buildings in earthquake-prone areas, when the difference in elevation between the facades of the buildings is more than 6 meters, or when the buildings have staggered floors with a large difference in floor slab elevation, or when the structural stiffness and mass of different parts of the buildings are completely different, adjacent parts of the buildings may collide with each other and cause damage during an earthquake; it is necessary to design seismic joints to divide the building into several independent units with simple shapes and uniform structural stiffness in order to avoid earthquake damage.

[0003] After construction, seismic isolation joint covers need to be installed at the seismic joint locations to cover and protect the seismic joints. However, since the width of traditional seismic joints is 50-100mm, the traditional seismic isolation joint cover structure has a small deformation capacity during use and cannot meet the deformation requirements of large-span seismic isolation joints. At the same time, the existing seismic isolation joint covers only have the function of accommodating deformation and cannot play a role in buffering and restoring during earthquakes. Therefore, they cannot effectively protect the building structure during earthquakes.

[0004] Based on this, the present invention proposes a construction structure for a large-span seismic isolation joint cover plate to solve the problems existing in the prior art. Utility Model Content

[0005] In view of this, the main purpose of this utility model is to provide a construction structure for a large-span seismic isolation joint cover plate, so as to solve the problems that the traditional seismic isolation joint cover plate has small deformation capacity, cannot meet the deformation requirements of large-span seismic isolation joints during use, and cannot play a role in buffering and resetting during earthquakes.

[0006] To achieve the above objectives, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A construction structure for a large-span seismic isolation joint cover plate is provided at the outer opening of the seismic isolation joint between two adjacent buildings. It includes a seismic isolation joint buffer and reset mechanism installed inside the seismic isolation joint. The seismic isolation joint buffer and reset mechanism is connected to the building through connectors on both sides. The connectors are fixed to the building by expansion bolts. Seismic dampers are provided on both connectors. A seismic isolation joint cover plate is provided on the upper end of the seismic damper.

[0008] In a preferred embodiment, the seismic isolation joint buffer reset mechanism is movably embedded within the seismic isolation joint, comprising:

[0009] Fireproof rock wool components are embedded in the vibration isolation joints, and galvanized steel plates are installed on the outside of the fireproof rock wool components.

[0010] The waterproof part is arranged on the upper side of the fireproof rock wool part and is connected with the galvanized steel plate.

[0011] In a preferred embodiment, the connecting part is further provided with a horizontal guide plug at one end close to the waterproof part, which is matched with a guide slot arranged on the waterproof part.

[0012] In a preferred embodiment, the upper end anchor head of the connecting anchor rod is matched with a movable slot arranged on the isolation joint cover plate; the lower end of the connecting anchor rod extends into the waterproof part, and a limiting nut is arranged on the connecting anchor rod in the waterproof part.

[0013] In a preferred embodiment, a spring is movably arranged on the connecting anchor rod, and the upper and lower ends of the spring are in contact with the isolation joint cover plate and the waterproof part respectively.

[0014] In a preferred embodiment, the isolation joint cover plate is provided with a plurality of horizontal displacement blocks at both ends close to the connecting part, which are matched with displacement slots arranged on the connecting part.

[0015] In a preferred embodiment, the displacement blocks and the displacement slots are both trapezoidal structures matched with each other, and the inner width of the displacement slot is greater than the width of the outer opening.

[0016] In a preferred embodiment, the anti-seismic damper is a viscoelastic damper, which comprises:

[0017] an upper connecting plate;

[0018] a damping column arranged at the lower end of the upper connecting plate and extending into the inner cavity of the damper base, and a plurality of layers of center plates are arranged on the damping column in the inner part of the damper base, which are matched with a plurality of layers of rubber viscoelastic damping plates arranged in the damper base.

[0019] In a preferred embodiment, a baffle is further arranged on the damping column at the upper end movable opening of the damper base.

[0020] Compared with the prior art, the large-span isolation joint cover plate construction provided by the present application has the following beneficial effects:

[0021] 1. The setting of the isolation joint buffer reset mechanism and the connecting part can reset and support the isolation joint after building vibration and earthquake, effectively ensuring the structural safety of the isolation joint.

[0022] 2. The setting of the isolation joint cover plate and the connecting parts on both sides of the isolation joint cover plate can expand the movable range of the connecting part during building vibration, so that it can be applied to the protection of large-span isolation joints.

Figures 1 to 6 The large-span seismic gap cover plate construction structure will be further described in detail below in combination with the drawings and the embodiments of the present application.

[0039] In one embodiment, a large-span isolation joint cover plate construction is installed at the outer opening of the isolation joint 11 between two adjacent buildings 1, which includes an isolation joint buffer reset mechanism installed in the isolation joint 11 along the length direction of the isolation joint 11, the isolation joint buffer reset mechanism is connected with the buildings 1 through the connecting pieces 4 on both sides, the connecting pieces 4 are installed on the front side structure surface of the buildings 1 through the expansion bolts 9, and the seismic dampers 7 are arranged on both of the connecting pieces 4, the upper end of the seismic damper 7 is further provided with the isolation joint cover plate 6, the outer end opening of the isolation joint 11 is blocked through the isolation joint cover plate 6, and the isolation joint cover plate 6 is further connected with the isolation joint buffer reset mechanism through the connecting anchor rods 5 to form a whole large-span isolation joint cover plate construction.

[0040] It should be noted that the isolation joint buffer reset mechanism is embedded and installed in the isolation joint 11 through the connecting pieces 4 and the connecting anchor rods 5, and the reset action of the isolation joint buffer reset mechanism after deformation can realize the reset of the isolation joint 11 at the epicenter or after the earthquake, and can also absorb the energy of the buildings 1 during the vibration process, thereby playing a reset supporting role.

[0041] It is worth noting that the outer end of each of the two connecting pieces 4 is close to the side of the outer side decoration surface of the building 1, and is adhesively connected with the outer side decoration surface of the building 1, so as to ensure the integrity of the connecting piece 4 and the building 1 after installation; and the connecting piece 4 is located on both sides of the isolation joint cover plate 6 and is movably connected with the isolation joint cover plate 6, so that the displacement range of the connecting piece 4 during the vibration process of the building 1 is expanded, and the connecting piece 4 can be applied to the protection of large-span isolation joints.

[0042] As shown in Figure 1 and Figure 2 The isolation joint buffer reset mechanism is movably embedded in the isolation joint 11, which includes a fireproof rock wool piece 2 and a waterproof piece 3, the fireproof rock wool piece 2 is embedded in the isolation joint 11, and a ring of galvanized steel plate 21 matched with the fireproof rock wool piece 2 is arranged on the outer side of the fireproof rock wool piece 2; the waterproof piece 3 is adhesively connected with the galvanized steel plate 21 on the outer side of the upper end of the fireproof rock wool piece 2, so that the fireproof rock wool piece 2 and the waterproof piece 3 can form an integral structure, and the waterproof piece 3 is further connected with the connecting pieces 4 and the connecting anchor rods 5.

[0043] It should be noted that the fireproof rock wool piece 2 is made of fireproof rock wool, which can support the two buildings 1 and also has a fireproof effect; the galvanized steel plate 21 can not only protect the fireproof rock wool piece 2 from external erosion and damage, but also can resist and reset.

[0044] It is worth mentioning that the waterproof member 3 is made of waterproof material, and has the same width as the seismic joint 11, which can prevent external water flow from entering the position of the fireproof rock wool member 2 during use, and has a waterproof effect; at the same time, it has a connecting effect, connecting the fireproof rock wool member 2, the connecting member 4 and the connecting anchor rod 5 to form a whole.

[0045] As shown in Figure 1 , Figure 2 and Figure 3 , the connecting member 4 is provided with a horizontal guide plug 41 at one end close to the waterproof member 3, the guide plug 41 is matched with a guide groove 31 opened in the inner side of the waterproof member 3, and the length of the guide groove 31 is greater than that of the guide plug 41, so that when the two buildings 1 vibrate, the guide groove 31 can give way to the movement of the guide plug 41, to ensure the safety of the structure.

[0046] As shown in Figure 1 and Figure 2 , the middle part of the seismic joint cover plate 6 is also provided with a movable slot 61 for giving way to the connecting anchor rod 5, which gives way to the movement of the connecting anchor rod 5 through the movable slot 61 during use, and the movable slot 61 is also matched with the upper end anchor head of the connecting anchor rod 5, to prevent the upper end anchor head of the connecting anchor rod 5 from sliding out of the movable slot 61 during movement.

[0047] As shown in Figure 1 and Figure 2 , a spring 8 is movably sleeved on the connecting anchor rod 5, the upper and lower ends of the spring 8 are in contact with the seismic joint cover plate 6 and the waterproof member 3 respectively, which can reset when the positions of the waterproof member 3 and the seismic joint cover plate 6 change or deform.

[0048] As shown in Figure 1 and Figure 2 , in order to ensure the connecting effect of the connecting anchor rod 5 and the waterproof member 3, a limiting nut 51 is threadedly connected to the end of the connecting anchor rod 5 extending into the waterproof member 3.

[0049] As shown in Figure 1 , Figure 2 and Figure 4 , the two ends of the seismic joint cover plate 6 close to the connecting member 4 are provided with a plurality of horizontal giving way blocks 62, which are matched with the giving way slots 42 provided on the connecting member 4; after installation, the giving way blocks 62 are inserted into the giving way slots 42, and move in the giving way slots 42 during vibration.

[0050] It should be noted that the said let go block 62 and let go slot 42 are all matching trapezoidal structure, and the inside width of let go slot 42 is greater than the outside opening width, so that let go block 62 can produce relative extrusion and friction with let go slot 42 when moving in let go slot 42, realizing the movable connection of isolation joint cover plate 6 and connecting piece 4.

[0051] As Figure 1 、 Figure 2 、 Figure 5 and Figure 6 , the said anti-vibration damper 7 is a viscoelastic damper, including upper connecting sheet 71, damping column 72 and damper base 73, the upper connecting sheet 71 is connected with isolation joint cover plate 6 through connecting bolt, the damping column 72 is arranged at the lower end of upper connecting sheet 71, extends to the inner cavity of damper base 73, and a plurality of layers of center plates 76 are arranged on the damping column 72 inside the damper base 73, the center plate 76 is used in cooperation with a plurality of layers of rubber viscoelastic damping plates 75 arranged inside the damper base 73, and the rubber viscoelastic damping plate 75 is located on both sides of the center plate 76.

[0052] It should be noted that through the friction force between the rubber viscoelastic damping plate 75 and the center plate 76, the movement of the damping column 72 in the damper base 73 can be damped, and the energy caused by internal friction and intermolecular interaction is converted into heat energy, thereby reducing the amplitude and frequency of vibration.

[0053] It is worth mentioning that the damper base 73 is also provided with a baffle 74 on the upper end of the movable port of the damping column 72, which isolates the internal environment of the damper base 73 from the external environment, avoiding direct contact of the internal structure with air, thereby improving its aging resistance.

[0054] The use process of the large-span isolation joint cover plate construction structure includes: during installation, through the installation sequence of inside first and outside later, first, the isolation joint buffer reset mechanism is installed in the isolation joint 11, then the isolation joint buffer reset mechanism is fixed through the connecting piece 4, finally, the isolation joint cover plate 6 is installed, and the isolation joint cover plate 6 is connected with the waterproof piece 3 through the connecting anchor rod 5, forming a whole large-span isolation joint cover plate construction structure, realizing the installation of the structure in the isolation joint 11.

[0055] The above is only a preferred embodiment of the present application, and is not used to limit the protection scope of the present application.
