Description
Technical field
The present invention relates to the prefabricated apparatus field of concrete component, is fixed more particularly to a kind of concrete prefabricated element template
Component.
Background technology
In order to make up the phenomenon that crack occurs too early in concrete, used in component（Loading）In the past, concrete one was given in advance
Individual precompression, i.e., in the tensile region of concrete, reinforcing bar is carried out tensioning, utilizes the retraction of reinforcing bar by the method that manually reinforces
Power, concrete in tension area is set to be stressed in advance.This precharge pressure stored, when component bears to produce pulling force by external load
When, the precompression in concrete in tension zone is offset first, then increases with load, just makes concrete in tension, and which limits mixed
The elongation of soil is coagulated, delays or crack occurs, the concrete of such a form is prestressed concrete.Due to prestressed concrete
Soil has the advantages that crack resistance is good, rigidity is big, deadweight vertical shear and principal tensile stress small, that can reduce beams of concrete, can
The stability and fatigue performance of compression member are significantly improved, there is excellent applying value in existing building construction.
The link of slurries seepage when preventing concreting is directed in prestressed concrete casting process, and it is many anti-
The effect of spillage technology fails to get a desired effect, and causes to directly affect efficiency of construction and the quality of concreting.It is existing
Typically all directly contacted with steel plate using steel plate and compressing, increase only slurry bar etc., to prevent concrete slurry seepage, but this side
Method not only adds certain difficulty to construction, also fails to reach preferable mortar leakage prevention effect.
The content of the invention
The link of slurries seepage when preventing concreting for being directed in above-mentioned prestressed concrete casting process,
And the effect of many mortar leakage prevention technologies fails to get a desired effect, cause to directly affect efficiency of construction and concreting
The problem of quality, the invention provides a kind of concrete prefabricated element template fixing component.
To solve the above problems, concrete prefabricated element template fixing component provided by the invention passes through following technical essential
To solve problem：Concrete prefabricated element template fixing component, including grillage, fixation clip and movable pressing board, the fixed pressure
Plate is fixed on grillage, and fixation clip and movable pressing board are in face relation, is had between fixation clip and movable pressing board and is used to press from both sides
The gap of template is held, in addition to the follower bolt being threadedly connected on grillage, the axis of the follower bolt are located at the gap
Width, the end of the follower bolt and the contact outside of movable pressing board, in addition to spring and check bolt are described anti-
Loose bolt thread is connected on grillage, and the diameter parallel of the axis of check bolt and hold-down bolt, and the spring is arranged at work
Between dynamic pressure plate and check bolt, in working condition, both ends of the spring is located by the compression of movable pressing board and check bolt respectively
In elastic compression.
Specifically, it is used for the clamping of concrete prefabricated element template with upper fixture, it is mixed to be inserted in the template after clamping
Solidifying soil sand slurry, so, die cavity of the template as concrete mortar are concrete prefabricated required for being obtained after concrete mortar solidification
Component.In the prior art, to reduce amount of contraction of the concrete mortar in process of setting, can typically be added in concrete mortar
Swelling agent, however, generally concrete mortar still has small contraction, for prestressed concrete, the above, which is shunk, is
The important origin cause of formation of slurries seepage when pouring.
In this case, when template closes mould, by rotating hold-down bolt, the end of hold-down bolt acts on the outer of movable pressing board
Side, is fixed the specified gap width of pressing plate and movable pressing board, in above gap after fill concrete mortar, can pass through rotation
Check bolt, makes spring produce the elastic deformation in compressive state, and above elastic deformation is that movable pressing board is produced to fixation clip
The thrust of side, so, in mixed mud mortar solidification process, if concrete mortar shrinks, the deformation of above spring is produced
Raw elastic force forces to be brought into close contact between template and mixed mud mortar, mixed mud mortar and sealing strip, sealing strip and template, is reached
To reducing spillage amount or avoid the technique effect of spillage.
This case,, can before fill concrete mortar after movable pressing board and fixation clip spacing is adjusted when using
Increasing a both ends in movable pressing board and fixation clip, the distance rod with both interior side contacts, preferably distance rod are located at gap respectively
Upper end, then pass through check bolt compression spring.After fill concrete mortar, concrete mortar solidification is treated to a certain extent,
When i.e. concrete mortar has some strength, then distance rod is removed, to avoid the elastic force of spring to fixation clip and movable pressing board
Between the size of die cavity impact.
Further technical scheme is：
As a kind of concrete scheme being easily achieved, the grillage takes the shape of the letter U, and the fixation clip and movable pressing board are located at plate respectively
The inner side of frame openend not homonymy.In above structure, grillage can be threadedly connected to by check bolt and hold-down bolt simultaneously
Side, the adjustment for the compression of complete paired springs and to movable pressing board position.
Because the amount of contraction of mixed mud mortar is smaller relative to gap width between fixation clip and movable pressing board, therefore it is profit
In mortar leakage prevention effect, the larger spring of coefficient of elasticity is preferably selected, the spring is the bullet being formed by stacking by multiple disk springs
Spring group.
It is excessive crooked to avoid movable pressing board from occurring under the bullet stress of spring, it is described beneficial to prefabricated components forming quality
Spring is one, the axis of the spring and the axis collinear of hold-down bolt, in addition to locking with the cooperation of hold-down bolt gap
Plate, the locking plate are arranged between spring and check bolt, the stress that the locking plate is used between spring and check bolt
Transmit, more than one of the check bolt, and different check bolts are arranged at the not homonymy of hold-down bolt.
It is excessive crooked to avoid movable pressing board from occurring under the bullet stress of spring, it is described beneficial to prefabricated components forming quality
Spring is more, and more springs are annularly uniform relative to the axis of hold-down bolt, in addition to coordinate with hold-down bolt gap
Locking plate, the locking plate are arranged between spring and check bolt, and the locking plate is used between spring and check bolt
Stress transmission, more than one of the check bolt, and different check bolts are arranged at the not homonymy of hold-down bolt.
For ease of rotating hold-down bolt and check bolt, it is provided with the hold-down bolt and check bolt for braking
The turning handle of each autorotation.
The invention has the advantages that：
In this case, when template closes mould, by rotating hold-down bolt, the end of hold-down bolt acts on the outside of movable pressing board,
It is fixed the specified gap width of pressing plate and movable pressing board, can be anti-by rotating in above gap after fill concrete mortar
Loose bolt, makes spring produce the elastic deformation in compressive state, and above elastic deformation is that movable pressing board is produced to fixation clip one
The thrust of side, so, in mixed mud mortar solidification process, if concrete mortar shrinks, produced by the deformation of above spring
Elastic force force and be brought into close contact between template and mixed mud mortar, mixed mud mortar and sealing strip, sealing strip and template, reach
Reduce spillage amount or avoid the technique effect of spillage.
