Description

Movable clamping anti-seismic support

Technical Field

The utility model belongs to the technical field of pipeline antidetonation auxiliary stand, concretely relates to can assemble in a flexible way and dismantle and can increase the regulation formula antidetonation support of prestressing force to each independent member.

Background

The existing cable pipeline or air duct used for the top surface of a building is characterized in that an expansion thread sleeve is driven into a top plate (ceiling) and connected with an expansion thread as a hanging piece, the connection strength is weak, when an earthquake occurs, a building body can swing, the pipeline arranged along the top surface of the building body can swing along with the cable and other components, the swinging of the components can not be eliminated automatically, the swinging amplitude of the components can be gradually intensified along with the swinging of the building, even the resonance phenomenon can occur with the swinging of the building, the fixed part of the pipeline component can be damaged due to the repeated high-strength swinging action, the pipeline component and the internal important component can be damaged, and the damage degree of the earthquake is enlarged.

The prior art for solving the above problems is mostly implemented by reinforcing a pipe fixing component, for example, the anti-seismic support disclosed in publication No. CN 208670283U is the most typical, and the anti-seismic support includes a first support rod extending perpendicular to an axial direction of a pipe, a second support rod extending obliquely along the axial direction of the pipe, and a third support rod extending along a radial direction of the pipe, and the anti-seismic support further includes a pipe clamp assembly sleeved on the pipe, the pipe clamp assembly includes a first pipe clamp and a second pipe clamp arranged adjacently, and both the first pipe clamp and the second pipe clamp are sleeved on the pipe; one end of each of the first support rod and the third support rod is fixedly connected with the first pipe hoop, the other end of each of the first support rod and the third support rod is fixedly connected with the mounting surface, one end of each of the second support rods is fixedly connected with the second pipe hoop, and the other end of each of the second support rods is fixedly connected with the mounting surface; a fourth supporting rod is further connected between the first supporting rod and the second supporting rod, and a fifth supporting rod is further connected between the first supporting rod and the third supporting rod. It can be seen that the antidetonation support that this scheme provided improves pipeline fixing component's intensity mainly from three-dimensional angle, makes pipeline fixing component's stiff end become a plurality ofly, and draw the pipeline from different angles, this scheme has certain antidetonation effect, still has intensity limit, when the magnitude of earthquake is higher, because the gravity of pipe member is very big, the mode that relies on the intensity that improves pipeline fixing component alone still has the drawback, building frequency of oscillation is great and the range increases along with the number of swings, can be broken through the restraint limit of pipe member joint strength, can cause destruction to a great extent.

Therefore, the method of pulling and fixing the duct member from multiple angles can significantly improve the stability of the duct member, but has a strength limit, and when the strength limit is broken, the greater damage is often caused. If the strength is improved by means of improving the material consumption of the fixing part, such as increasing the thickness of the material, the construction cost is greatly increased, the number of hanging pieces for fixing the pipeline member is large, the general cost increasing mode is adopted for preventing accidental events, obviously, the feasibility is poor, especially, the current situation of market competition is fierce, the market share is greatly reduced by the general cost increasing mode, the normal and continuous development of enterprises is not facilitated, and the existing damping support member still needs to be improved.

Or the outer side of the supporting rod is sleeved with an outer sleeve supporting tube. And be located bracing piece or overcoat stay tube bilateral symmetry position and outside position and be connected with the pull rod as in fig. 2 respectively, all be connected with the cutting ferrule sub-assembly in every pull rod to when exerting the pulling force to each pull rod, be about to in the joint of each cutting ferrule sub-assembly inserts corresponding cover seat, make each pull rod provide the pulling force and the support component (bracing piece or overcoat stay tube 6) provides the top thrust, this kind of pulling force and top thrust are reaction force, can continuously increase the pulling force of each pull rod and reach certain degree, thereby pulling force and thrust all have prestressing force. Sufficient prestressing force can be applyed to activity joint antidetonation support to this embodiment to improve its antidetonation stability.

Example 4: a tool dedicated to a snap fit assembly, as shown in fig. 9, comprises an i-shaped bracket 901, which comprises an upper wing plate, a lower wing plate and a middle web plate. A fixed side shaft 902 is vertically connected between two sides of the upper and lower wing plates of the i-shaped bracket, as shown in fig. 11, and a rotating sleeve 903 is sleeved outside the fixed side shaft 902.

The rotating sleeve can rotate on the fixed side shaft, and can rotate together with components such as gears and the like after rotating as shown in fig. 13, so that the handle can rotate and swing up and down. The gap between the two gears can be enlarged by operating the handles at the two sides to realize the left-right swing, as shown in fig. 14 and 15, the two gears of the special tool are transversely unfolded and clamped at the two sides of the clamping joint, so that the gears are meshed with racks at the two sides of the clamping joint, and the clamping joint can be driven to move up and down when the handles at the two sides are simultaneously pulled up and down.

Furthermore, after the card connector is inserted into the sleeve seat (the card connector can be easily inserted into the sleeve seat by a proper depth through manual operation), the pushing force can be exerted through the special tool. Specifically, as shown in fig. 17, an outward protruding clamping table is disposed at an inlet edge of the sleeve seat, when the special tool is used, the lower wing plate 910 of the i-shaped bracket needs to be supported below the clamping table 504 in a matching manner, or the upper wing plate of the i-shaped bracket needs to be supported above the clamping table 504 in a matching manner, or the lower wing plate of the i-shaped bracket needs to be supported above the clamping table 504 in a matching manner, so as to constrain the i-shaped bracket. The clamping joint is clamped between the gears on the two sides by swinging the handle left and right, and the handle is rotated upwards or downwards to push the clamping joint to enter and exit.

Above structure mainly realizes pressing the joint through the specialized tool brute force in the cover seat, in fact, when with the inside compression gear of handle, can make two forks pole elastic deformation inwards of joint through the extrusion force of two gears to can realize impel and two kinds of operations of pulling out.
