Description
Technical field
The invention belongs to Architectural Equipment technical field, in particular to a kind of combined steel for beams of concrete enlarging section
Mould bases.
Background technique
When being reconstructed to existing structure, it is often necessary to enlarging section processing is carried out to beams of concrete, it is old to increase
The load performance of beam；It at this time just needs to use mould bases, mould bases is generally formed by template assembly, is coated and fixed in the outer of old beam
It encloses, there is the space of grouting between the outer surface of old beam；After mould bases fixes, concrete grout is poured into space, concrete
The section of old beam is just increased after solidification, it can also be around the steel mesh that the setting of old beam newly adds, mud certainly in the space of grouting
After solidification, newly plus steel mesh in conjunction with concrete, stress performance can be increased.
But the existing mould bases for beams of concrete enlarging section is generally adopted by wooden form composition, wooden form week
Turning property, accuracy, surface smoothness are poor, easily-deformable；And conventional combined type mould bases volume is larger, and external force is needed to support,
Therefore also many support columns need to set, on the ground, structure is complex for support, at high cost and be not easy to and install.
Summary of the invention
In order to overcome the shortcomings of the prior art, the present invention provides a kind of combinations for beams of concrete enlarging section
Formula steel mould base, side form and lower die pass through bar planting fixation kit and are directly anchored on the former concrete of old beam or on steel mesh,
Support system is not needed, cost is reduced.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of combined steel mould bases for beams of concrete enlarging section, the combined steel mould bases include side form, lower die
With bar planting fixation kit；The lower die is used to be arranged in the downside of old beam；Side form is used to be arranged in the arranged on left and right sides of old beam；Institute
It states and is equipped with bar planting through hole in side form and the lower die；The bar planting fixation kit and bar planting through hole cooperate, and are used for side
Bar planting is fixed on the former concrete of old beam or is weldingly fixed on the new plus steel mesh anchored with old beam respectively for mould and lower die；
One lower die and the sealing assembly of left and right two side forms are fixedly connected as a combined steel mould bases.
One of above-mentioned technical proposal is used for the combined steel mould bases of beams of concrete enlarging section, including arranged on left and right sides
Side form, a lower die, side form and lower die are that steel plate is made and supports, and are distinguished side form and lower die by bar planting fixation kit
Bar planting is fixed on the former concrete of old beam or is weldingly fixed on to be added on steel mesh with the new of old beam anchoring；It does not just need so
The structural member of support system can greatly simplify structure, reduce cost, remarkable in economical benefits；And steelwork, connection dimension can be more
What is added is accurate, can be tightly combined between docking structure, and better effect of casting, butt seam is small and smooth, is less prone to spillage
Pour effect beauty；Because steelwork is rigidly good, durability is strong, and it is thick and solid like that not need wooden form, thus it is small in size, more
Convenient for combination installation, physical life is longer.
Preferably, the side form includes multiple side templates, and the assembly of sealing two-by-two of adjacent two side template is fixedly connected, group
Dress up side form.If the length of beam body is longer, also Ying Jiachang then can be by very long side for the ease of transport for corresponding side form
Film is divided into multiple side form plates and is assembled, and is convenient in this way.
Preferably, the lower die is in the cover shape of back-off, and to lower recess, surrounding has upwardly extended flange part, two sides for centre
Flange part be side flange portion, the upper surface of side flange portion is used to be fixedly connected with the sealing assembly of the lower end surface of left and right side form；Before
The flange part at end is lordosis edge, and the flange part of rear end is rear flange portion, and the upper surface of forward and backward flange part is used to and old beam
Support sealing in lower end surface.Lower die has recess, so that the bottom of lower die can bear bigger mud using the cover shape of back-off
Starch gravity, conventional lower die it is flat, mud under gravity, is easy to be extruded；And lower die is recess herein, recess
Edge do not have gap, therefore be not easy spillage.
Preferably, the lower die includes a preceding lower template, lower template after lower template and one at least one；It is front lower
Template be equipped with lordosis edge, rear lower template be equipped with rear flange portion, preceding lower template, rear lower template, middle lower template two sides be equipped with
Side flange portion；Preceding lower template, lower template is fixedly connected with lower template sealing assembly after one at least one, is assembled into lower die.
When beam body is very long, lower die needs to grow very much accordingly, is formed by connecting, is convenient in such a way that multiple lower templates assemble.
Preferably, it is equipped at the assembled seam of the steel mould base for sealing the assembled rib side being fixedly connected, rib Bian Shangshe
There is rib side through hole, rib is spliced to form splicing seams while with rib, is fixedly connected by anchor bolt or punching block card or screw and mutually to splice
Rib side.The docking plane on rib side is generally plane, naturally it is also possible to some stepped interfaces for being collocated with each other design, limit
It, can be with lift-off seal while the docking of position；Rib side can also use some conventional Design of Reinforcement simultaneously, be not easy rib side
It is deformed.
Preferably, bar planting fixation kit includes anchor pole, butterfly button and for the steel pipe as stress frame；The anchor pole
One end protrude into bar planting through hole for bar planting be fixed on the former concrete of old beam or be weldingly fixed on old beam anchoring it is new
Add on steel mesh；The steel pipe is equipped with through hole, and the other end of the anchor pole runs through the through hole of steel pipe, and passes through butterfly button
Steel pipe is locked on side form or the lateral surface of lower die.
Preferably, the corresponding butterfly of the lower die, which is buckled, is locked as double steel pipe.The gravity that lower die is born is bigger, it is advantageous to
For double steel pipe；Certainly, in certain embodiments, even single steel pipe, can also be arranged on the downside of lower die by increasing
The number of bar planting fixation kit supplements stress-bearing capability.
Preferably, the axis of the steel pipe in lower die is set for front and back trend；The axis for the steel pipe being arranged on side form is
Trend up and down.Corresponding endurance is stronger.
Preferably, the horizontal plane where the upper surface of the side form is lower than the upper end of the old beam, is formed with grouting gap.
Gap be in the milk for the mud externally to penetration concrete between steel mould base medial surface and old beam；In certain embodiments,
Grouting gap can not be stayed and directly open up grout hole in the upper end of side form.
The beneficial effects of the present invention are: a kind of combined steel mould bases for beams of concrete enlarging section of the invention, packet
Include left and right two side forms, a lower die, side form is that steel plate is made with lower die, by bar planting fixation kit by side form and under
Bar planting is fixed on the former concrete of old beam or is weldingly fixed on the new plus steel mesh anchored with old beam mould respectively；So just
The structural member of support system is not needed, structure can be greatly simplified, reduces cost, remarkable in economical benefits；And steelwork, connection dimension
It can more precisely can be tightly combined between docking structure, better effect of casting, butt seam is small and smooth, is not easy out
Existing spillage pours effect beauty；Because steelwork is rigidly good, durability is strong, and it is thick and solid like that not need wooden form, so volume
It is small, combination installation is easily facilitated, physical life is longer.
