Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and more particularly to an adaptive earthquake-resistant mechanical support frame for construction engineering. Background Art

[0002] Prefabricated components for prefabricated buildings are typically manufactured in factories and transported to on-site for assembly. Joints between prefabricated components are typically connected by post-casting concrete or grouting at the joints. For example, prefabricated beams and load-bearing columns often have pre-reinforced steel bars at their joints. During hoisting, these bars are overlapped or welded together before the formwork is supported and concrete poured. After pouring, prefabricated beams cannot immediately bear load; the concrete must solidify and reach sufficient strength before further construction can proceed. Therefore, temporary support frames are often installed to temporarily support the prefabricated beams. To shorten construction schedules, construction work is often carried out at other locations after concrete pouring. Vibration generated by this construction work can cause vibrations in the prefabricated beams, potentially affecting the concrete as it solidifies. After the concrete solidifies and the formwork is removed, support systems such as corbels or bearings on the load-bearing columns are often retained. Because the corbels are in direct contact with the prefabricated beams, the rigid connection between the corbels and the prefabricated beams can weaken the seismic performance of the joints when subjected to vibrations from building renovations or renovations. Therefore, how to improve and enhance the seismic performance of the building during the wet connection process and after the concrete solidifies is the technical problem to be solved by the present invention.

[0012] Preferably, the damper is a second damper, one end of the second damper is connected to the connector, and the other end is connected to the bottom of the prefabricated beam, the second through hole is arranged along the axial direction of the load-bearing column or the temporary support frame, the second damper is composed of a limiting bottom plate, a limiting top plate and a second reset member, a third connecting member is provided at the bottom of the limiting bottom plate, the limiting bottom plate is connected to the second through hole through the third connecting member, one end of the second reset member is connected to the top surface of the limiting bottom plate, and the other end is connected to the bottom surface of the limiting top plate, and the limiting top plate is connected to the bottom of the prefabricated beam.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] The damper can be arranged between the prefabricated beam and the temporary support frame, usually on the top of the temporary support frame, so that the prefabricated beam can be placed on the damper when the prefabricated beam is hoisted (such as Figure 1a and Figure 1b As shown, see the first embodiment below); the damper can also be connected to the bottom of the prefabricated beam, and the damper can be set on the load-bearing column or on a temporary support frame (such as Figure 1c and Figure 1d As shown, see the second embodiment below for details). It should be noted that when the damper is set on the load-bearing column through the support system, it is necessary to avoid the damper from affecting the disassembly and assembly of the casting formwork. The damper usually set on the load-bearing column remains on the load-bearing column after the formwork is removed, thereby reducing the impact of vibration on the precast beam. One end of the support system is connected to the fixer so that the support system can be fixed to the load-bearing column or the temporary support frame. Regardless of whether the damper is connected to the bottom of the precast beam or set between the precast beam and the temporary support frame, when the precast beam is wet-connected to the load-bearing column and waiting for the concrete to solidify, regardless of whether the precast beam is shaking in a single linear direction (such as left and right, up and down, front and back) or twisting in the axial direction, the damper can always support the precast beam and provide a reset trend for the precast beam. When the concrete solidifies and the formwork is removed, and the building is renovated or renovated and vibration occurs, the damper installed on the load-bearing column can still adapt to the vibration of the precast beam, thereby improving the overall seismic performance of the building.

[0016] The other advantages, objectives and features of the adaptive seismic-resistant mechanical support frame for construction engineering described in the present invention will be partially reflected in the following description and will also be understood by those skilled in the art through research and practice of the present invention.

DETAILED DESCRIPTION

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0033] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0034] As shown in the figure, the present invention provides an adaptive seismic mechanical support frame for construction engineering, including: a fixer arranged on a load-bearing column or a temporary support frame, the fixer is a prior art, and can be a hoop or a supporting formwork and other related structures, a support system 1 is provided on the fixer, the support system 1 can be a support or a bracket, the support system 1 is arranged along the radial direction of the load-bearing column or the temporary support frame, and a damper is provided at one end of the support system 1 away from the load-bearing column or the temporary support frame, the damper can be arranged between the prefabricated beam and the temporary support frame, usually at the top of the temporary support frame, so that the prefabricated beam can be placed on the damper when hoisting the prefabricated beam (such as Figure 1a and Figure 1b As shown, see the first embodiment below); the damper can also be connected to the bottom of the prefabricated beam, and the damper can be set on the load-bearing column or on a temporary support frame (such as Figure 1c and Figure 1d As shown, see the second embodiment below for details), it should be noted that when the damper is set on the load-bearing column through the support system 1, it is necessary to avoid the damper from affecting the disassembly and assembly of the casting formwork. Usually, the damper set on the load-bearing column will still remain on the load-bearing column after the formwork is removed, thereby reducing the impact of vibration on the precast beam.

[0035] One end of the support system 1 is connected to the fixer so that the support system 1 can be fixed on a load-bearing column or a temporary support frame. Regardless of whether the damper is connected to the bottom of the precast beam or is arranged between the precast beam and the temporary support frame, when the precast beam is wet-connected with the load-bearing column and waiting for the concrete to solidify, regardless of whether the precast beam is shaking in a single linear direction (such as left and right, up and down, front and back) or twisting in the axial direction, the damper can always support the precast beam and provide a reset trend for the precast beam; after the concrete solidifies and the formwork is removed, when the building is renovated or renovated and vibrations are generated, the damper installed on the load-bearing column can still adapt to the vibration of the precast beam and improve the overall seismic performance of the building.

[0036] Furthermore, a mounting assembly is provided at one end of the support system 1 away from the load-bearing column or the temporary support frame, and the damper is connected to the support system 1 via the mounting assembly.

[0037] Furthermore, a mounting groove and a cover plate 2 are provided at the bottom of the support system 1, and a first through hole is provided at the top of the support system 1. The first through hole passes through the support system 1 and is connected to the mounting groove. The mounting component is arranged in the mounting groove and extends from the first through hole to the top of the support system 1. The cover plate 2 is used to encapsulate the mounting component in the mounting groove.

[0038] Furthermore, the mounting assembly is composed of a first reset member 3, a first adjuster 4, a ball joint 5 and a connector 6. The first reset member 3 is generally an elastic member, such as a spring or an elastic block. The first reset member 3 is arranged in the mounting groove. The first adjuster 4 is arranged on the cover plate 2 and extends into the mounting groove. The first adjuster 4 is connected to one end of the first reset member 3 through a first transmission member 31. Figure 10 As shown, the first transmission member 31 is a steel plate that can contact the end of the first reset member 3, and the first adjuster 4 can be a bolt. The position of the first transmission member 31 is adjusted by rotating the bolt so that the first transmission member 31 can squeeze the first reset member 3.

[0039] The other end of the first reset member 3 is connected to one end of the ball head connecting rod 5 through the second transmission member 32, so that the action force of the first reset member 3 can be transmitted to the ball head connecting rod 5, and transmitted to the damper via the ball head connecting rod 5, and the ball head connecting rod 5 can be prevented from escaping from the first through hole. The other end of the ball head connecting rod 5 is a ball head end, and the ball head end of the ball head connecting rod 5 is connected to the connector 6, so that no matter whether the prefabricated beam drives the damper to shake up and down, swing horizontally, or twist axially during vibration, the connector 6 can be connected to the support system 1 through the ball head connecting rod 5.

[0040] Furthermore, a limiting ring 51 is provided on the outer wall of the ball joint 5. The bottom of the limiting ring 51 abuts against the top of the support system 1, supporting the connector 6 and the damper before the damper contacts the precast beam. It should be noted that the limiting ring 51 does not conflict with the first reset member 3. It is possible to set only the first reset member 3 without the limiting ring 51, or only set the limiting ring 51 without the first reset member 3, or both can be provided at the same time. Figure 10 When the limiting ring 51 and the first reset member 3 are provided simultaneously, the first reset member 3 is usually adjusted by the first adjuster 4 before the damper contacts the precast beam, thereby separating the limiting ring 51 from the support system 1. The damper then contacts the precast beam until the limiting ring 51 abuts against the support system 1.

[0041] Furthermore, the connector 6 is provided with at least one second through hole for mounting a damper. The second through hole is a threaded hole to facilitate the installation of the damper. The bottom of the connector 6 is provided with a ball joint end. The bottom of the ball joint end is provided with a spherical groove adapted to the ball end of the ball joint connecting rod 5. The connector 6 is connected to the ball joint connecting rod 5 via the ball joint end.

[0042] In this embodiment, we provide a damper with the simplest structure, which is a first damper 7. The first damper 7 is arranged between the prefabricated beam and the temporary support frame. Figure 1a、 Figure 1b and Figure 2 As shown, when the prefabricated beam vibrates, the first damper 7 can support the prefabricated beam while reducing the transmission of vibration, and the first damper 7 will transmit the vibration directly to the temporary support frame in the axial direction. The support system 1 only needs to provide radial force to maintain the first damper 7 between the prefabricated beam and the temporary support frame, and will not fall out from between the prefabricated beam and the temporary support frame when vibration occurs. Therefore, the second through hole is arranged along the radial direction of the temporary support frame, and a second adjuster 8 is arranged in the second through hole. The second adjuster 8 can be a screw, and the first damper 7 is connected to the connector 6 through the second adjuster 8.

[0043] Furthermore, the first damper 7 is composed of a filling piece 71 and a fixing piece 72. The first damper 7 is tapered, so that the first damper 7 is conveniently taken out from between the prefabricated beam and the temporary support frame. The thickness of the first damper 7 at one end away from the connector 6 is less than the thickness of the first damper 7 at one end close to the connector 6. Figure 3 and Figure 5 As shown, usually the distance from the filling piece 71 (the end away from the connector 6) to the connector 6 is greater than the distance from the fixing piece 72 (the end away from the connector 6) to the connector 6, thereby ensuring that only the filling piece 71 is located between the prefabricated beam and the temporary support frame. Usually the filling piece 71 is an elastic piece, and the fixing piece 72 is a rigid piece. The fixing piece 72 is an arc-shaped plate, and the fixing piece 72 is arranged on the side wall of the filling piece 71 through the first connecting piece 73. The fixing piece 72 is provided with a second connecting piece 74 on the side away from the filling piece 71, and a third through hole 741 is provided on the second connecting piece 74. The second adjuster 8 is connected to the second connecting piece 74. When the second adjuster 8 is a screw, the screw can be screwed to pull the fixing piece 72 through the second connecting piece 74, and finally the filling piece 71 is pulled out from between the prefabricated beam and the temporary support frame, thereby facilitating disassembly while ensuring that the first damper 7 can provide good support and vibration transmission to the prefabricated beam. When disassembling the temporary support frame, the first damper 7 is usually taken out first to facilitate the disassembly of the temporary support frame.

[0044] Furthermore, the filler 71 is provided with at least one fourth through hole 711, which is provided in the vertical direction, and is usually two in number. Figure 4 、 Figure 6 and Figure 7 As shown, the fourth through hole 711 constitutes a deformation space for the filling piece 71, which can achieve a shock-absorbing effect when the prefabricated beam vibrates, regardless of whether the prefabricated beam shakes or twists.

[0045] In the above embodiment, we provide a first implementation of the damper. Because this implementation needs to be set between the prefabricated beam and the temporary support frame, it is necessary to adjust the position of the first damper 7 (the filling piece 71) in advance before the prefabricated beam is hoisted, and in order not to affect the pouring of concrete at the node, the first damper 7 can only be set on the temporary support frame to support the prefabricated beam.

[0046] After the concrete of the node solidifies and reaches the strength standard, with the removal of the temporary support frame, the first damper 7 can no longer support the precast beam. For this reason, we provide a second damper implementation method, which is a second damper 9. One end of the second damper 9 is connected to the connector 6, and the other end is connected to the bottom of the precast beam. Because the second damper 9 adopts a method of supporting and reinforcing the bottom of the precast beam, its position is far away from the load-bearing column and the casting node of the precast beam. Therefore, in this embodiment, the second through hole needs to be arranged along the axial direction of the load-bearing column or the temporary support frame. Because both implementation methods require the setting of a second through hole, but the setting position of the second through hole is different, in order to increase the versatility of the connector 6, four second through holes are usually set on the connector 6, two for connecting to the first damper 7, and two for connecting to the second damper 9.

[0047] Furthermore, the second damper 9 is composed of a limiting bottom plate 91, a limiting top plate 92 and a second reset member 93. The bottom of the limiting bottom plate 91 is provided with a third connecting member, and the limiting bottom plate 91 is connected to the second through hole through the third connecting member. Usually, the third connecting member can be provided with an external thread, so that the third connecting member is threadedly connected to the second through hole, and the third connecting member can also be welded to the second through hole. One end of the second reset member 93 is connected to the top surface of the limiting bottom plate 91. The second reset member 93 is an elastic member, which can be a spring or an elastic block. The other end is connected to the bottom surface of the limiting top plate 92, and the limiting top plate 92 is connected to the bottom of the precast beam. A limiting sleeve 94 is provided on the top surface of the limiting bottom plate 91, and a limiting column 95 is provided on the bottom surface of the limiting top plate 92. The limiting column 95 is located in the limiting sleeve 94. When the precast beam vibrates, the limiting column 95 can move in the limiting sleeve 94.

[0048] Because the second damper 9 will not affect the casting of the node between the precast beam and the load-bearing column, the second damper 9 can usually be set on the corbel of the load-bearing column. When the concrete strength of the casting node meets the standard, the second damper 9 is retained, so that the precast beam and the corbel can be non-rigidly connected, thereby greatly improving the seismic performance of the building. It should be noted that the second damper 9 has stronger versatility than the first damper 7, so the second damper 9 can be used on a temporary support frame. However, in order to avoid excessive compression or damage to the second damper 9, the second damper 9 has higher requirements for the hoisting position of the precast beam than the first damper 7, and it needs to be repeatedly debugged. Therefore, the first damper 7 is usually used as a temporary part, and the second damper 9 is used as a permanent part, and the two are used in combination.
