Description
Technical field
The present invention relates to the prefabricated apparatus fields of concrete component, fix more particularly to a kind of concrete prefabricated element template
Component.
Background technique
Occur the phenomenon that crack too early to make up concrete, used (load) in the past in component, and gave concrete one in advance
A precompression, i.e., in the tensile region of concrete, reinforcing bar is carried out tensioning, utilizes the retraction of reinforcing bar by the method manually reinforced
Power makes concrete in tension area in advance by pressure.This precharge pressure stored, when component bears to generate 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 for coagulating soil, delays or crack occurs, the concrete of such form is prestressed concrete.Due to prestressed concrete
Soil has many advantages, such as that crack resistance is good, rigidity is big, self weight vertical shear and principal tensile stress small, that can reduce beams of concrete, can
The stability and fatigue performance for significantly improving compression member have excellent applying value in existing building construction.
The link that slurries leak 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 leads to the quality for directly affecting construction efficiency and concreting.It is existing
It is generally all directly being contacted using steel plate with steel plate and is compressing, increases to stop and starch item etc., to prevent concrete slurry from leaking, but this side
Method not only increases certain difficulty to construction, also fails to reach ideal mortar leakage prevention effect.
Summary of the invention
For be directed in above-mentioned prestressed concrete casting process prevent concreting when slurries leakage link,
And the effect of many mortar leakage prevention technologies fails to get a desired effect, and leads to directly affect construction efficiency and concreting
The problem of quality, the present invention provides a kind of concrete prefabricated element template fixing components.
To solve the above problems, concrete prefabricated element template fixing component provided by the invention passes through following technical essential
To solve the problems, such as: 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 relationship, is had between fixation clip and movable pressing board for pressing from both sides
The gap for holding template, further includes the hold-down bolt being threadedly connected on grillage, and the axis of the hold-down bolt is located at the gap
Width direction, the end of the hold-down bolt and the outer side contacts of movable pressing board further include spring and check bolt, described anti-
Loose bolt thread is connected on grillage, and the axis of check bolt is parallel with the axis of hold-down bolt, and the spring is set to 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, the clamping of concrete prefabricated element template is used for upper fixture, it is mixed to be inserted in the template after clamping
Solidifying soil sand slurry, in this way, type chamber of the template as concrete mortar, concrete prefabricated required for obtaining after concrete mortar solidification
Component.In the prior art, it to reduce shrinkage of the concrete mortar in process of setting, can generally be added in concrete mortar
Swelling agent, however, concrete mortar still has small contraction under normal circumstances, for prestressed concrete, the above contraction is
The important origin cause of formation that slurries leak 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, rotation can be passed through in the above gap after fill concrete mortar by obtaining the specified gap width of fixation clip and movable pressing board
Check bolt, generating spring is in the elastic deformation of compressive state, and the above elastic deformation is that movable pressing board is generated to fixation clip
The thrust of side, in this way, if concrete mortar is shunk, the above spring deformation is produced in mixed mud mortar solidification process
Raw elastic force forces to be fitted closely 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 technical effect of spillage.
This case,, can before fill concrete mortar after adjusting movable pressing board and fixation clip spacing when using
Increasing a both ends in movable pressing board and fixation clip, the distance rod with the two interior side contacts, preferably distance rod are located at gap respectively
Upper end, then pass through check bolt compressed spring.After fill concrete mortar, to a certain extent to concrete mortar solidification,
When i.e. concrete mortar has some strength, then remove distance rod, to avoid spring elastic force to fixation clip and movable pressing board
Between the size of type chamber impact.
Further technical solution are as follows:
As a kind of concrete scheme being easily achieved, the grillage is in U-shape, and the fixation clip and movable pressing board distinguish position
In the inside that grillage open end is not ipsilateral.In the above structure, plate can be threadedly connected to simultaneously by check bolt and hold-down bolt
The side of frame, the adjustment for the compression of complete paired springs and to movable pressing board position.
It since the shrinkage of mixed mud mortar is smaller relative to gap width between fixation clip and movable pressing board, therefore is benefit
In mortar leakage prevention effect, the biggish 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 described conducive to prefabricated components forming quality to avoid movable pressing board that excessive skew occurs under the bullet stress of spring
Spring is one, and the axis of the spring and the axis collinear of hold-down bolt, further include locking with hold-down bolt clearance fit
Plate, the locking plate are set between spring and check bolt, and the locking plate is for the stress between spring and check bolt
Transmitting, more than one of the check bolt, and different check bolts are set to the not ipsilateral of hold-down bolt.
It is described conducive to prefabricated components forming quality to avoid movable pressing board that excessive skew occurs under the bullet stress of spring
Spring is more, and more springs are annularly uniformly distributed relative to the axis of hold-down bolt, further includes and hold-down bolt clearance fit
Locking plate, the locking plate are set between spring and check bolt, and the locking plate is used between spring and check bolt
Stress transfer, more than one of the check bolt, and different check bolts are set to the not ipsilateral of hold-down bolt.
To be provided with for braking on the hold-down bolt and check bolt convenient for rotating hold-down bolt and check bolt
The turning handle of each autorotation.
The invention has the following advantages:
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, rotation can be passed through in the above gap after fill concrete mortar by obtaining the specified gap width of fixation clip and movable pressing board
Check bolt, generating spring is in the elastic deformation of compressive state, and the above elastic deformation is that movable pressing board is generated to fixation clip
The thrust of side, in this way, if concrete mortar is shunk, the above spring deformation is produced in mixed mud mortar solidification process
Raw elastic force forces to be fitted closely 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 technical effect of spillage.
