Background

In the temporary structure, the temporary support has a very wide application as a temporary supporting structure with adjustable height. A temporary support is arranged at the top of the support frame, and elevation adjustment of the template support system is achieved through the effect that the height of the temporary support can be adjusted. And after the structure construction is finished, the template supporting system is separated from the main concrete structure by adjusting the height of the temporary support. And providing a working space for the removal of the formwork support system.

The liftable temporary support for the heavy-load template combined support system, with the application number of 201721440145.9 and the application date of 2017-11-01, comprises a support bottom plate, a support top plate, a support screw rod and a locking nut; the support top plate is provided with a through hole, the upper end of the supporting screw penetrates through the through hole upwards and then is fixed on the support top plate through locking nuts arranged on two sides of the through hole, and the lower end of the supporting screw is pressed against the upper surface of the support bottom plate; be provided with two lock nuts on the supporting screw, these two locking screw threads are located the both sides of via hole for the support roof, but the liftable support is placed to heavy-duty template combination support system in shaped steel pole setting bottom, can satisfy the altitude variation of support frame to a certain extent, can be through down adjusting the support height and then conveniently supporting dismantling of system when the support frame is demolishd simultaneously. The support adopts an all-steel structure, and is easy to cause structural damage due to welding seams, corrosion and the like; due to the limitation of the processing precision of the temporary structure, the temporary support is easy to have local stress concentration when in use, so that local damage is caused, and further, the integral damage is caused; the structural design can not bear the load action of more than 2000 kN; the four wedge-shaped blocks adopted by the structure have different structures and are poor in universality and economy.

Disclosure of Invention

An object of the utility model is to overcome prior art's shortcoming, provide one kind and can bear and exceed 2000kN load, the structure is more firm safety, whole atress is more reasonable, receive the steel sheet combination concrete temporary support that machining precision influences less, the commonality is good.

The utility model discloses a steel sheet combination concrete temporary support structure, including the cuboid structure that four bodies that the structure is the same are constituteed, every the body include the cell body that the longitudinal section is the structure of falling the trapezium, open at every cell body bottom surface central point position have a through-hole, every the cell body about the top of lateral wall upwards extend along vertical direction respectively and form left side vertical lateral wall and right side vertical lateral wall, the lateral wall of the same one side of left side vertical lateral wall and right side vertical lateral wall and cell body contained angle be 135 degrees, the bottom wall of cell body and the lateral wall about the cell body contained angle be 135 degrees, be fixed with the board of falling the trapezium that coincides with the longitudinal section shape of body along vertical direction respectively in the logical groove at the notch of both ends around every the cell body and in the logical inslot of cell body, all filled with the concrete in each empty groove that board and cell body enclose, a reserved through hole communicated with the through hole is reserved in the concrete at the position corresponding to the through hole, and the through hole and the reserved through hole form a threaded rod mounting hole;

a threaded rod passes the threaded rod mounting hole of two bodies of horizontal direction, the both ends of threaded rod be connected with clamp plate and nut respectively, two the clamp plate compress tightly on the concrete outer wall through the nut that corresponds the setting respectively, the cuboid structure in the body of below be used for laying on interim support top, control the lateral wall of the lower side wall of two bodies and support on the lateral wall of the homonymy of the body of below, the both sides lateral wall of the body of top support respectively about on the last lateral wall of body and with die block braced system direct contact.

The utility model has the advantages that: the device is used for temporary structure construction, and the support descends after construction is completed. The temporary support depends on the combination of the four steel plate combined concrete trapezoidal blocks, and the height of the whole system of the temporary support is adjusted by adjusting a nut which transversely penetrates through finish-rolled deformed steel bars or a high-strength screw. Due to the adoption of the steel plate combined concrete structure, the bearing capacity of the temporary support can be greatly improved by fully utilizing the performances of various materials. Meanwhile, the temporary support adopts a four-block-shaped trapezoidal structure with the same shape, so that the replaceability is good, and the turnover performance and the utilization rate are improved. Can realize industrialized and standardized production. The number of concrete labels and the size and the number of the counter-pulling screws (finish-rolled deformed steel bars) can be replaced according to the required bearing capacity during processing. So that the method can be widely applied to construction of various temporary structures.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The utility model discloses a steel sheet combination concrete temporary support structure, including the cuboid structure that four bodies 1 that the structure is the same constitute, every the body include that longitudinal section is the cell body 2 of falling trapezium structure, at every cell body bottom surface central point open and to have a through-hole, every the cell body about the top of lateral wall upwards extend along vertical direction respectively and form left side vertical side wall and right side vertical side wall, left side vertical side wall and right side vertical side wall and cell body with the contained angle α of the lateral wall of one side be 135 degrees, cell body 2's diapire and cell body about the contained angle β of lateral wall be 135 degrees, at every the cell body around the notch of both ends department and in the logical inslot of cell body respectively along vertical direction be fixed with the identical inverted trapezoid board 3 of the longitudinal section shape of body, all pour into concrete 354 in each empty groove that inverted trapezoid board 3 and cell body enclose have the through-hole of reservation with the through-hole intercommunication in concrete 4 of through-hole corresponding position, through-hole and reservation through-hole constitute the mounting hole.

When the concrete 4 is poured, holes are reserved in the concrete through pre-buried PVC pipes in the concrete 4 at the positions corresponding to the through holes, and the holes are used as mounting holes of threaded rods (finish-rolled deformed steel bars or high-strength threaded rods).

A threaded rod 5 passes two body 1's of horizontal direction threaded rod mounting hole, the both ends of threaded rod 5 be connected with clamp plate 6 and nut 7 respectively, two clamp plate 6 compress tightly on the concrete outer wall through the nut that corresponds the setting respectively.
