Abstract
The utility model relates to an induced seam structure of basement roof belongs to the relevant technical field of building engineering. Mainly include: two supporting beam and be located two the intermediate lamellas between the supporting beam, the top between a supporting beam is the floor arrangement of reinforcement, for induced seam between the floor arrangement of reinforcement, should be covered by the rubber waterstop by induced seam. Adopt the utility model discloses an induced seam structure does not basically increase engineering cost in the work progress, measures such as UEA admixture, prestress application are more economical than adding.
Description
Technical field
This utility model relates to architectural engineering correlative technology field, specifically, relates to a kind of basement roof attractive joint knot
Structure.
Background technology
In recent years, along with the development of China's economy, various places constantly emerge the building of the big scale of construction, wherein have the biggest one
Partly belong to super-long structural.And along with using the development in pluralism of function, architect is to not setting seam (expansion joint) xoncrete structure
The requirement of plane length is more and more higher, and various Overlong Concrete Structure constantly occur, wherein the control of distress in concrete be one very
Important problem.
And in architectural engineering, the crack of xoncrete structure is more universal, the type in crack is also a lot, and Overlong Concrete Structure easily goes out
Existing temperature shrinkage fracture has the trend gradually increased, although this kind of crack belongs to non-structural crack, typically will not affect component and hold
Load power and structural safety, but durability and the globality of structure can be affected.The most also can give user sense organ and cause psychologically
Harmful effect.Overlong Concrete Structure is easily produced cracking by the dual function of temperature stress Yu shrinkage stress.
For avoiding cracking, it is common practice to arrange concrete temperature post-cast strip.But post-cast strip has the disadvantage in that
(1) staying the temperature post-cast strip in basement roof, typically secondary construction again after top board construction completes 2 months, when this section
In, the precipitation in the area that level of ground water is shallower can not stop, and will inevitably drop into various in temperature post-cast strip
Rubbish incidental, owing to top board structure reinforcing bar is relatively slightly closeer so that cleaning work is the most difficult.
(2) under temperature post-cast strip runs through entirely, superstructure, place of arrival meets beam and breaks beam, meets plate and breaks plate, brings much to construction
Inconvenience, affects construction speed.
(3) before temperature post-cast strip filling concrete, both sides concrete dabbing need to be constructed extremely difficult, and certain structures concrete
Longer with temperature post-cast strip concreting time interval, the adhesion strength of New-old concrete it is difficult to ensure that, again owing to pouring time difference,
The drying shrinkage major part causing the concrete of these structures completes before temperature post-cast strip fills.Therefore, temperature post-cast strip concrete
Drying shrinkage easily in the generation crack, junction of New-old concrete.Underground engineering and other have the place of waterproof requirement, add
Hidden leakage defect.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, it is provided that a kind of basement roof attractive joint structure.
Use attractive joint structure of the present utility model in work progress, the most do not increase construction costs, than add UEA additive,
The measures such as Shi Hanzhang are more economical.
In order to reach above-mentioned purpose, this utility model adopts the following technical scheme that
A kind of basement roof attractive joint structure, including:
Dual-gripper beam and the intermediate plate between dual-gripper beam, the top between support beam is floor arrangement of reinforcement；
Being attractive joint between floor arrangement of reinforcement, this attractive joint is covered by rubber fastening band.
Preferably, described intermediate plate is extruded sheet.
Preferably, described rubber fastening band and floor arrangement of reinforcement airtight connection.
Preferably, outside described rubber fastening band, airtight connection has additional waterproofing layer.
Preferably, described floor arrangement of reinforcement has kink.
The beneficial effects of the utility model are:
(1) reduction of erection time, the concrete at attractive joint can be with continuous placing.
(2) by arranging some attractive joint at basement roof interval, make to become the more weak district of stress at each attractive joint, continuously
In work progress crack concentrate at attractive joint occur, it is to avoid basement roof Large Area Cracking, reduce engineering cost and
Ensure that construction quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Wherein: 1, rubber fastening band, 2, support beam, 3, extruded sheet, 4, floor arrangement of reinforcement, 5, additional waterproofing layer, 6,
Attractive joint, 7, kink.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail.
Embodiment: a kind of basement roof attractive joint structure, its structure is as it is shown in figure 1, include support beam 2 and be positioned at two
Intermediate plate between support beam 2, intermediate plate is used for formwork for placing, and can be chosen to extruded sheet 3.Extruded sheet full name squeezes
Mould polystyrene foam plate, be called for short extruded sheet, have another name called XPS plate.It is to be aided with polymer with polystyrene resin to add hot mixing
While, injecting catalyst, then squeeze out the rigid foam plate of seriality closed-cell foam.Extruded sheet has the lowest
The heat conductivity (only 0.028W/M.K) of value and unfailing excellent insulation and compressive property, comprcssive strength up to
220-500Kpa。
The top of described support beam 2 is floor arrangement of reinforcement 4；Being attractive joint 6 between floor arrangement of reinforcement 4, this attractive joint 6 is stopped by rubber
Water band 1 covers.In order to improve waterproof effect, the outside of rubber fastening band 1 also has additional waterproofing layer 5.
Described floor arrangement of reinforcement 4 has kink 7 near the place of attractive joint 6.
Before basement roof concrete pouring construction, extruded sheet 3, as the forming panel of described attractive joint 6, is positioned at two
Between support beam 2.After basement roof concreting molding, it is not necessary to take out extruded sheet 3, attractive joint 6 can be formed.
In this utility model, the top board arrangement of reinforcement at attractive joint reduces, and the longitudinal reinforcement retaining 50% passes through, when overall structure is because of temperature
When the reasons such as difference, concrete shrinkage and/or differential settlement cause STRESS VARIATION, can ftractureing in advance in cross section, attractive joint place, releases
Put the energy in concrete, to avoid overall structure, at non-design, crack occurs.
When boundary of works area is bigger, it is spaced molding said structure, the concrete cracking of ad-hoc location can be realized, it is to avoid concrete
Random cracking, and then greatly improve construction speed, and substantially there is no extra construction cost.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses this utility model.Right
The multiple amendment of these embodiments will be apparent from for those skilled in the art, as defined herein typically
Principle can realize in the case of without departing from spirit or scope of the present utility model in other embodiments.Therefore, this practicality
The novel the embodiments shown herein that is not intended to be limited to, and be to fit to and principles disclosed herein and features of novelty phase
The widest consistent scope.
