According to the cooling pipe network system provided by the utility model, the steel pipe is utilized to support the reinforcing steel bars of a base plate, so that the supporting is reliable; the building is convenient; the reinforcing steel bars on the upper part of the base plate are prevented from sinking; and the steel pipe is used as a cooling pipe, the cold water is injected and the heat conductivity of the steel pipe is utilized to reduce the hydration heat in mass concrete, so that high-temperature crack is prevented from generating in the mass concrete and pouring quality is ensured.
Description
Technical field
The utility model relates to a kind of concrete in mass (concrete structure entity minimum dimension is not less than the big scale of construction concrete of 1m) base plate reinforced bar support that is used for, and reduces the structure of setting up of the inside concrete heat of hydration simultaneously.More particularly, the utility model is about supporting the multistory reinforced cooling pipe network system of mass concrete invert.
Background technology
Prior art is when the mass concrete invert reinforcing bar binding, and the Steel bar rack that adopts the welding of i iron or reinforcing bar is usually buried coating steel pipe reduces concrete in mass as the cooling pipe the heat of hydration underground as reinforced bar support at the base plate middle part.In base plate reinforcing bar binding process, first colligation bottom reinforcement bars is set up steel pipe frame again; On steel pipe frame, put the middle part and lay coating steel pipe as the cooling pipe; Put upper reinforcement again, place i iron or Steel bar rack then, remove steel pipe frame then as reinforced bar support.The defective of this method is; Operating personnel need in the base plate reinforcing cage, to construct when laying insulating tube, place i iron or Steel bar rack and removing steel pipe frame; It is not easy to operate and dangerous bigger to construct, and the coating steel pipe cost that is adopted in addition is higher, needs special method to fix.
Summary of the invention
The purpose of the utility model is the weak point that exists to above-mentioned prior art, provides a kind of support reliable, sets up conveniently; Safe; Construction costs can be reduced, can the fastener steel tube frame of cooling can be doublely made again as mass concrete construction reinforced bar support frame.
The utility model solves the technical scheme that its technical problem adopted: a kind of multistory reinforced cooling pipe network system of building base plate that supports; Comprise; Begin to set up steel pipe support from the raft bottom edge and support multistory reinforced fastener steel tube; It is characterized in that; The vertical rod 3 that connects the upper, middle and lower horizon bar of useful fastener all to irritate plug with cement paste closely knit, the horizon bar scaffolding height is made by bar diameter, row's number, protective layer thickness, be provided with vertical bracing continuously around the raft plate and by post apart from the horizontal cross brace that adds up and down; Be arranged on 5 one conduct outlets of middle part horizon bar of said fastener steel tube frame, one is equipped with the compression pump 13 that in pipeline, injects cold water absorption hydration heat of concrete.
The utility model has following beneficial effect than prior art.
The utility model utilizes the steel pipe of fastener steel tube frame to make concrete in mass cooling pipe; Inject cold water, utilize its thermal conductivity, reduce the heat of hydration that is produced in the casting of concrete in mass process; Can prevent the inner appearance temperature of concrete in mass crack, guarantee pouring quality.Adopt fastener steel tube to set up the bracing frame of base plate reinforcing bar, not only reliable to reinforced bar support, set up conveniently, avoid the base plate upper reinforcement to sink, and need not to be provided with in addition i iron or Steel bar rack, remove steel pipe frame, practice thrift the duration, and be beneficial to construction safety.The horizon bar that utilizes fastener steel tube frame middle part has been practiced thrift construction costs as concrete in mass cooling pipe, has satisfied the cooling requirement that reduces the concrete in mass heat of hydration simultaneously.
Description of drawings
Fig. 1 is that the utility model supports the multistory reinforced cooling steelpipe net system phantom drawing of building base plate.
Fig. 2 is the lateral view of Fig. 1.
Among the figure: 1. concrete floor, 2. concrete cushion, 3. vertical rod, 4. upper level bar; 5. the double middle part horizon bar of doing the cooling pipe, 6. middle part horizon bar, 7. cushion block, 8. base plate upper reinforcement; 9. base reinforcing bar, 10. base plate middle part reinforcing bar, 11. snap joints, 12. welding points; 13. pressure pump, 14. horizontal cross braces, 15. vertical bracings.
The specific embodiment
Consult Fig. 1.Use in the cooling steelpipe net support system in the multistory reinforced construction of the mass concrete invert of following description, the fastener steel tube frame is set up on concrete floor 1.Base plate middle part reinforcing bar 10, the 8 difference colligations of base plate upper reinforcement are on the middle part of fastener steel tube frame horizon bar 6 and upper level bar 4.The fastener steel tube frame begins to set up steel pipe support from the raft bottom edge and supports base plate middle part steel muscle 10 and upper reinforcement 8.The middle part horizon bar 6 that is positioned at fastener steel tube frame middle part line or arranged connects into a closed conduct by snap joint; When building underplate concrete; Double 5 one setting pressure pumps of middle part horizon bar of doing the cooling pipe inject cold water in pipeline; The other end is as outlet, below place a water container, flow in the water container from pipe outlet after absorbing hydration heat of concrete through cold water through pipeline.When concreting, with pressure pump 13 water is poured in the double steel pipe 5 of doing cooling pipe in middle part, the current steel pipe flows out from the opposing party, puts into the big glue bucket of preprepared.The double middle part horizon bar 5 of doing the cooling pipe can be according to concrete in mass thermometric scheme, and the cooling tube pitch is arranged in concrete floor 1 middle part.
Behind the good base plate reinforcing bar of colligation, adopt fastener steel tube to begin to set up steel pipe support and support from the raft panel edges, make the horizon bar scaffolding height by bar diameter, row's number, protective layer thickness, this horizontal steel tube bears the upper reinforcement load.All arrays are arranged, connect with fastener go up, that the vertical rod 3 of middle horizon bar is all irritated plug with cement paste is closely knit, and vertical bracing 15 is set continuously around the raft plate and by post apart from the twice horizontal cross brace 14 that adds up and down.For avoiding destroying waterproofing course, all lay cushion block 7 in the lower end of above-mentioned vertical rod 3.Cushion block 7 is a granite.With the steel pipe vertical rod 3 and steel pipe horizon bar that fastener connects, the double steel pipe 5 of doing the cooling pipe in middle part directly adopts snap joint 11 to connect, and curved connecing adopted welding point 12.
