Abstract
The present invention relates to reinforced concrete foundation beam field, specially a kind of construction of reinforced concrete foundation beam expansion joint setting.On the basis of the beam-ends for two reinforced concrete foundation beams being connected with same foundation is shelved on, it is separated between the part that beam-ends is in contact with basis with asphalt felt, outrigger is set in beam end, keeps expansion joint and enclosure wall expansion joint co-located, avoids wall crazing.Easy for construction, advantages of simple of the invention effectively solves reinforced concrete foundation beam expansion joint and the inconsistent caused wall crazing phenomenon of wall expansion joint.
Description
Technical field
The present invention relates to reinforced concrete foundation beam field, specially a kind of reinforced concrete foundation beam expansion joint setting
Construction.
Background technique
In actual engineering design, any structure be more than certain length after Temperature Joint should all be set.Usual situation
Under, the method for superstructure use setting twin columns achieves the goal, but cast-in-situ steel reinforced concrete foundation beam is because of its both ends need and base
Whole pour of plinth and cannot achieve.For the attainment of one's purpose, previous way is usually to use post-cast strip section construction.It does the post-cast strip of beam
I.e. in the appropriate location of beam, there are the width ranges of 800~1000mm not to be poured concrete for method, only by the elongated setting of reinforcing bar, to this
After complete 28 days of range two sides concreting, by the concrete surface dabbing of two sides, then it is poured more higher leveled than design strength mixed
Solidifying soil, and suitable reinforcing rib need to be set at post-cast strip.Above-mentioned Normal practice construction is very complicated, and the construction time is longer,
Influence construction speed.And in practical projects sometimes because post empiricism complexity unexpectedly cancels the Temperature Joint of foundation beam, it makes
It cracks at foundation beam because temperature is flexible, to bring security risk to building.
Summary of the invention
The purpose of the present invention is to provide a kind of constructions of reinforced concrete foundation beam expansion joint setting, are not influencing engineering
In the case where progress, reinforced concrete foundation beam Temperature Joint is rationally set.
The technical scheme is that
A kind of construction of reinforced concrete foundation beam expansion joint setting, two reinforced concretes being connected with same foundation
It on the basis of the beam-ends of plinth beam is shelved on, is separated between the part that beam-ends is in contact with basis with asphalt felt, is arranged in beam end
Outrigger keeps expansion joint and enclosure wall expansion joint co-located.
The construction of the reinforced concrete foundation beam expansion joint setting, on the basis of reinforced concrete foundation beam is shelved on
When, there are the expansion joints of 20~40mm between beam-ends and basis.
The construction of the reinforced concrete foundation beam expansion joint setting, is arranged on the upside of reinforced concrete foundation beam end
Outrigger, there are the expansion joints of 20~40mm between two outriggers, keep expansion joint and enclosure wall expansion joint co-located, two outriggers
Bottom and basis top between asphalt felt is set.
The construction of the reinforced concrete foundation beam expansion joint setting, the beam-ends of reinforced concrete foundation beam are directly fallen in
On the basis of；Alternatively, concrete pad, reinforced concrete foundation is arranged between the beam-ends of reinforced concrete foundation beam and the step on basis
Asphalt felt is set between the beam-ends bottom of beam and concrete pad.
The construction of the reinforced concrete foundation beam expansion joint setting, the size of asphalt felt is according to cast in place reinforced bar coagulation
The contact area of earth foundation beam and concrete pad, or the basic contact area to connect with reinforced concrete foundation beam are true
It is fixed.
The advantages of the present invention are as follows:
1, on the basis of the beam-ends of two reinforced concrete foundation beams that the present invention is connected with same foundation is shelved on, beam-ends and
It is separated between the part that basis is in contact with asphalt felt, outrigger is set in beam end, makes expansion joint and enclosure wall expansion joint position
In same position, wall crazing is avoided.
2, the Temperature Joint of the cast-in-situ steel reinforced concrete foundation beam in the present invention is easy for construction, advantages of simple, and not shadow
Construction speed is rung, and can satisfy design requirement completely, reinforced concrete foundation beam expansion joint is effectively solved and is stretched with wall
Wall crazing phenomenon caused by contracting seam is inconsistent.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In figure, 1 reinforced concrete foundation beam；2 bases；3 asphalt felts；4 outriggers；5 concrete pads.
Specific embodiment
The embodiment of the present invention combination attached drawing is described in detail below, but protection scope of the present invention is not by embodiment
It is limited.
As shown in Figure 1, the construction of overlength reinforced concrete foundation beam expansion joint setting of the present invention, mainly includes reinforced concrete
Earth foundation beam 1, basis 2, asphalt felt 3, outrigger 4, concrete pad 5 etc., specific structure is as follows:
The beam-ends for two reinforced concrete foundation beams 1 being connected with same foundation 2 is shelved on basis 2, beam-ends and basis 2
It is separated between the part being in contact with asphalt felt 3, outrigger 4 is set in beam end, is located at expansion joint with enclosure wall expansion joint
Same position.
When reinforced concrete foundation beam 1 is shelved on basis 2, there are the expansion joints of 30mm between beam-ends and basis 2.
Outrigger 4 is set on the upside of 1 end of reinforced concrete foundation beam, there are the expansion joint of 30mm between two outriggers 4, makes to stretch
Contracting seam is co-located with enclosure wall expansion joint, and asphalt felt 3 is arranged between the bottom of two outriggers 4 and the top on basis 2.
According to the influence of the factors such as the design requirement of reinforced concrete foundation back absolute altitude and embedded depth of foundation, armored concrete
The beam-ends of foundation beam 1 can be directly fallen on basis 2；Alternatively, being set between the beam-ends of reinforced concrete foundation beam 1 and the step on basis 2
Concrete pad 5 is set, asphalt felt 3 is set between the beam-ends bottom and concrete pad 5 of reinforced concrete foundation beam 1.
The size of concrete pad 5 should highly be designed according to the sectional dimension and back of reinforced concrete foundation beam 1 and be marked
Height determines.The size of asphalt felt 3 should according to the contact area of cast-in-situ steel reinforced concrete foundation beam 1 and concrete pad 5, or
The contact area on the basis 2 to connect with reinforced concrete foundation beam 1 determines.
