Abstract

A kind of removable stretching bed seat of build-in gravity type, including pedestal plate and anchoring part, it is characterized in that the pedestal plate is certain thickness R. C. ptates, two end of pedestal plate is equipped with thickening plate, the anchoring part includes column, bottom beam, horizontal beam and diagonal brace, and bottom beam level is coupled between adjacent columns lower end, and horizontal beam is series at the upper end of the column, diagonal brace upper end is coupled with column, and lower end is coupled with the thickening plate of pedestal plate.For the utility model using permanent thick concrete terrace as pedestal plate (top pillar), interim pedestal is with low investment, and anchoring part is convenient to assemble and disassemble and recyclable recycling, booth disappears at low cost, it has enough to meet the need high-efficient, also eliminates component conveying expense, component manufacturing cost is greatly reduced.

Description

The removable stretching bed seat of build-in gravity type

Technical field

The utility model relates to prefabricated components manufacturing field more particularly to a kind of manufacturing facilities of prestressing force prefabricated components.

Background technique

Pretensioned precast element manufacture, stretching bed seat is key facility, and when stretching force is very big, anchoring part passes to pedestal The horizontal pressure force of compression bar (top pillar) can be very big.Using the self weight of certain thickness R. C. ptates as balance compression pedestal plate Overall collapse lateral force be stretching bed seat technology a big innovation, but usually prestressing force prefabricated components are manufactured in factory, anchor Seat and plate platform seat are permanent reinforced concrete structure, and investment is big and component conveying is at high cost, and service radius is limited, precast plant Production smoothing is poor, to some mega projects for having site condition, as can then be greatly reduced into building site manufacture prefabricated components This, and market radius is unrestricted.It is a kind of (to be pushed up using the thick concrete terrace of road, stockyard or workshop terrace as pedestal plate Column), and anchor post is had not been reported using removable prestressed stretch-draw pedestal.

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiency of the above-mentioned prior art, a kind of peace side of tearing open is provided Just the removable stretching bed seat of build-in gravity type.

According to a kind of removable stretching bed seat of build-in gravity type provided by the utility model, including pedestal plate and anchoring part, It is characterized in that the pedestal plate is certain thickness R. C. ptates, two end of pedestal plate is equipped with thickening plate, and the anchoring part includes Column, bottom beam, horizontal beam and diagonal brace, bottom beam level are coupled between adjacent columns lower end, and horizontal beam is series at the upper end of the column, diagonal brace Upper end is coupled with column, and lower end is coupled with the thickening plate of pedestal plate.

Also there is following attached technical characteristic according to a kind of removable stretching bed seat of build-in gravity type provided by the utility model:

The pedestal plate is equipped with ground beam, and ground beam is laterally arranged in diagonal brace lower end.

The thickening plate of the pedestal plate has several piles.

The column of the anchoring part is box column, interior to be equipped with tabula stiffener.

The bottom beam of the anchoring part is H girder steel or channel steel.

The bottom beam top of the anchoring part is backfilled with sand.

Have compared with prior art according to a kind of removable stretching bed seat of build-in gravity type provided by the utility model as follows Advantage:

1, using permanent thick concrete terrace as pedestal plate (top pillar), interim pedestal is with low investment, anchoring part it is convenient to assemble and disassemble and Recyclable recycling, booth disappear at low cost, have enough to meet the need high-efficient, also eliminate component conveying expense, component manufacturing cost is greatly reduced.

2, anchoring part utilizes the self weight and passive earth pressure collective effect antidumping of backfill, and anchor post buried depth is small, anchor post Lower end displacement deformation is small, easy for construction.

3, the antidumping arm of force is increased using diagonal brace, the deformation of cantilever anchor post is small, and shrinkage prestress losses are small.

4, the lateral force being self-possessed using permanent road or terrace plate as abutment plate (compression bar) unstability is breached long thin Than the stress unstability restricted problem of king-sized compression bar, make it possible that plate as compression bar, also substantially saves interim pedestal Construction cost.In addition, optimization antidumping structure is set using the mixed mode of gravity antidumping and passive earth pressure antidumping Meter makes anchoring part have operability and economy.

Specific embodiment

Referring to Fig. 1 to Fig. 2, a kind of removable stretching bed seat of build-in gravity type that the utility model provides, including pedestal plate 1 With anchoring part 2, it is characterized in that the pedestal plate 1 is certain thickness R. C. ptates, 1 two end of pedestal plate is equipped with thickening plate 11.The anchoring part 2 include column 21, bottom beam 22, horizontal beam 23 and diagonal brace 24,22 level of bottom beam be coupled to 21 lower end of adjacent columns it Between, horizontal beam 23 is series at 21 upper end of column, and 24 upper end of diagonal brace is coupled with column, the thickening plate 11 of lower end and pedestal plate 1 Knot.The lateral force being self-possessed using permanent road or terrace plate as abutment plate (compression bar) unstability, it is special to breach slenderness ratio The stress unstability restricted problem of big compression bar makes it possible plate as compression bar, and the thickening plate at two end of plate is to meet The requirement of partial pressing.The antidumping arm of force is increased using diagonal brace 24, the column 21 of cantilever can be made to deform small, shrinkage prestress losses It is small.Using the mixed mode of gravity antidumping and passive earth pressure antidumping, optimize the design of antidumping structure, having anchoring part can Operability and economy.

Referring to Fig. 1 to Fig. 2, a kind of removable stretching bed seat of build-in gravity type that the utility model provides, the pedestal plate 1 Equipped with ground beam 12, ground beam 12 is laterally arranged in 24 lower end of diagonal brace, and support lower end sets lateral ground beam, and the pressure for transmitting support is opposite It equably passes in soil or in stake.The thickening plate 11 of the pedestal plate 1 has several piles 13, lower in foundation bearing capacity Area, the vertical pressure that transmit of support need to be resisted with stake.

Referring to Fig. 1 to Fig. 2, a kind of removable stretching bed seat of build-in gravity type that the utility model provides, the anchoring part is stood Column 21 is box column, and interior to be equipped with tabula stiffener 211, box column torsional property is good, and the tabula stiffener 211 inside set is for undertaking Local pressure.

Referring to Fig. 1 to Fig. 2, a kind of removable stretching bed seat of build-in gravity type that the utility model provides, the bottom of the anchoring part Beam is H girder steel, and bottom beam is pure bending resistance component, most reasonable using H steel stress.

Referring to fig. 2, a kind of removable stretching bed seat of build-in gravity type that the utility model provides, the bottom beam 22 of the anchoring part 2 Top is backfilled with sand 3, because sand is easy compacting, uses sand passive earth pressure can be made to meet as backfilling material and calculates requirement.
