The present invention provides a kind of grid structure plate bearing for taking reinforcement measure, including column sleeve, screed, mortar set, aperture steel sole plate, gasket, nut, anchor bolt, floor, support ball.Column sleeve is installed in reinforced concrete structure column upper end, screed installs mortar set, and aperture steel sole plate top is equipped with floor and support ball, and anchor bolt preburied in concrete structure, anchor bolt passes through screed and aperture steel sole plate is fixed by nut.Taking the grid structure plate bearing of reinforcement measure has good anti-seismic performance and deformability, and it is chipping by the pressure of steel sole plate to effectively prevent screed, and plate bearing is caused to lose vertical bearing capacity.It effectively prevents reinforced concrete structure top edge concrete to fall off due to the horizontal thrust by anchor bolt, causes support that brittle break occurs and lose its bearing capacity.Pedestal configurations of the present invention are simple, and application operability is strong, at low cost, can effectively avoid support that brittle break occurs, and can be widely applied to engineering reality.
Description
Technical field
The present invention relates to mixed structure more particularly to a kind of grid structure plate bearings for taking reinforcement measure.
Background technique
Grid structure is often used in the large span spatial structures such as museum, body skill shop, and overall structure anti-seismic performance is good
Good, refuge uses after frequently as calamity.In recent years both at home and abroad in multiple times earthquake centre find, for connect top Elements of Space Grid Truss with
The plate bearing of concrete structure destroys frequent occurrence, especially relatively conventional with concrete structure top edge failure mode.It should
The principal phenomena of kind failure mode is the concrete structure top surface in plate bearing, is generated from anchor bolt towards concrete edge
The damage and failure region of approximate 35 ° of diffusion angles, so that mass concrete is from falling from high altitude, this in building property and people
Body causes greatly to threaten safely, and drastically influence grid structure continues to use performance.Generate the basic of this kind of failure mode
Reason is that support anchor bolt generates the biggish plastic deformation of horizontal direction in earthquake, and support anchor bolt generates water to edge concrete
Flat-pushing power, in the case where the horizontal thrust is greater than concrete tensile strength, edge concrete is damaged.
Existing result of study shows to reduce structural edge by guaranteeing enough anchor bolts and the intermarginal clear distance of concrete edge
The stress of concrete makes concrete strain be less than ultimate tensile strength, avoids concrete structure edge that brittle break occurs.However
In grid structure design, top Elements of Space Grid Truss is often separately accounted for concrete structure, and the planar dimension of concrete structure is based on
The stress of self structure is designed, and is not considered to anchor bolt in plate bearing node and concrete edge range arm cun
Design.Therefore in actual design, often there is plate bearing and the lesser situation of concrete structure top edge clear distance, this is right
The anti-seismic performance of plate bearing concrete structure top surface is extremely disadvantageous.
The effective connection for guaranteeing top Elements of Space Grid Truss and concrete structure using the method for being easy to construct, avoids plate bearing section
The brittle break that edge concrete falls off occurs under geological process for point, guarantees the anti-seismic performance of grid structure, is grid structure
Plate bearing design method urgent problem to be solved.
Summary of the invention
The purpose of the present invention is overcoming the shortcomings of grid structure plate bearing design method, one kind is provided and takes reinforcement measure

Specific embodiment
Below in conjunction with attached drawing and technical solution, the specific embodiment of the invention is further illustrated.
Embodiment
A kind of grid structure plate bearing for taking reinforcement measure, including column sleeve 1, screed 2, mortar cover 3, aperture steel bottom
Plate 4, gasket 5, nut 6, anchor bolt 7, floor 8, support ball 9.Column sleeve 1 is installed in the upper end of concrete structure II, column sleeve 1 can be
Concrete structure II pour after the completion of install, also can choose it is pre-buried when concrete structure II pours, but need to guarantee column sleeve 1 with
Without obvious gap between concrete structure II.Four anchor bolts 7, the installation of II top surface of concrete structure are embedded in concrete structure II
Have and wears the screed 2 connect, aperture steel sole plate 4, gasket 5 and the double nut 6 connecting with anchor bolt 7 with anchor bolt 7.Aperture steel sole plate 4
It is welded by the floor 8 and support ball 9 that are welded with it, support ball 9 is welded with rod member for grid III.
Actual application of the invention is as follows, is required first according to structure stress, according to Specification Design top Elements of Space Grid Truss
Structural member III and lower part concrete structure II determine plan-position and the size of plate bearing I.Later, consider concrete knot
Edge damage occurs for structure II in 35 ° of development, to determine that altitude range is arranged in column sleeve 1.It is last to set up defences requirements according to earthquake-resistant structure, it counts
Intensity and thickness needed for column sleeve 1 under geological process are calculated, and the weld seam of column sleeve 1 is designed and is checked.Consider 2 thickness of screed
Determine the height of mortar set 3, steel plate thickness takes 6-10mm, and mortar set 3 can be used as screed 2 and pour mold.
When aperture steel sole plate 4 generates horizontal reciprocating effect under geological process, anchor bolt 7 can be made to produce surrounding concrete
Raw horizontal thrust, so that II top edge concrete of concrete structure is easy to happen tensile failure, column sleeve 1 can be to concrete structure
II generates Confinement effect, effectively prevents concrete and brittleness tensile failure occurs, and the anti-seismic performance and ductility for improving support become
Shape ability.
When aperture steel sole plate 4 generates rotational deformation under geological process, aperture steel sole plate 7 can be made to compress screed 2
Local pressure is generated, so that screed 2 occurs local compression and destroys, mortar set 3 can generate Confinement effect to screed 2, effectively
It avoids screed 2 to occur to destroy generation greatly deformation, improves the anti-seismic performance and ductile deformation's ability of support.
The present invention can the top concrete to concrete structure II play cuff and protective effect, particular for concrete
Thus the lesser side of Edge Distance avoids edge concrete that abruptly brittle rupture occurs, support is caused to lose bearing capacity.
