Description

A kind of novel fabricated concrete continuous beam dry type welding node
Technical field
The present invention relates to a kind of connecting nodes suitable for prefabricated assembled concrete continuous beam, can be used for prefabricated assembled The node of frame structure connects, and belongs to prefabricated concrete structure technical field in Structural Engineering.
Background technology
The main production task of prefabrication structure is completed in component factory, and scene need not carry out largely binding steel The work such as muscle, support template, casting concrete reduce the problem of noise pollution of construction site, improve the work of construction worker Make environment, improves construction speed and construction efficiency, it is more guaranteed to the quality of building.In order to meet the sustainable development of country Strategic thought improves the scientific and technical content of Building Trade in China, raises labour productivity, it is therefore necessary to be built to prefabricated assembled Building structure is furtherd investigate.
By construction operation difference, fabricated construction connection is broadly divided into wet type connection and is connected with dry type.So-called wet connection is just It is that prefabricated components are prefabricated to realize with the type of attachment of secondary casting concrete with site concrete according to corresponding design concept Connection between component;And involvement connects, and is the pre-buried connecting elements in prefabricated components, is then bolted or welds Mode realizes the connection between prefabricated components.
Current China in order to meet the globality of prefabricated concrete structure system, to the connection types of prefabricated components still with Based on wet construction.But wet connection node has the defect of cast-in-place concrete:Long construction period, environmental protection difference etc..With wet connection It compares, the dry type connection of prefabricated assembled concrete structure has the advantages such as speed of application is fast, wet construction is few, saving material, answers This is widely promoted.
In order to further improve dry type node connection type, raising dry type connecting node mechanical property, establish dry type connection Joint design method designs a kind of prefabricated assembled concrete beam dry type node, is very important.
Invention content
The purpose of the present invention is designing a kind of novel prefabricated assembled concrete continuous beam dry type welding node, to fill up It is domestic at present in the blank of continuous beam dry type node connection area, for domestic assembled dry type node development provide it is a kind of newly Method.
The present invention adopts the following technical scheme that in order to achieve the above object:
A kind of novel prefabricated assembled concrete continuous beam dry type welding node, it is characterised in that:Its described continuous beam section Point structure includes longitudinal reinforcement 1, stirrup 2, pre-embedded steel slab 3, steel deck-plate 4, epoxide-resin glue 5, and cover board punches 6, test beam 7, weldering Seam 8.
Further, test beam at beam length one third using carrying out being welded to connect for longitudinal reinforcement and pre-embedded steel slab; Steel deck-plate carries out cover board and punches before a splice;Test beam carries out prefabricated in factory.
Further, test beam reach design strength it is in place after, test beam connecting portion infusion epoxy resin glue into Row bonds.
Further, the left and right beam section of continuous beam is bonded by epoxide-resin glue, after reaching intensity, by pre-embedded steel slab with Steel deck-plate is attached by welding.
Further, the size of steel deck-plate is equal to the size of two pre-embedded steel slabs, and steel deck-plate is overlying on left and right beam section pre-embedded steel slab Pre-embedded steel slab and steel deck-plate are spliced using welding manner in outside.
The present invention can obtain following advantageous effect:Present invention construction raw material are easy to get, and save cost, work progress Middle wet-less operation facilitates construction, has many advantages, such as environmental protection and energy saving, safe and reliable and durable, has broad application prospects.

Specific implementation mode
To keep present disclosure more obvious and easy to understand, it is described further with reference to the accompanying drawings and detailed description.
As shown in figs. 1 to 6, prefabricated assembled concrete continuous beam dry type welding node of the invention using dry type node into Row connection, specific connection type are as follows:First beam end or more pre-embedded steel slab 3 is being tested in prefabricated test beam 7 respectively;Into one Step, after beam 7 to be tested is in place, bonded using epoxide-resin glue 5;Further, wait for that continuous beam 7 meets intensity requirement After, both sides pre-embedded steel slab 3 is spliced in 3 outside of reserved steel plate using steel deck-plate 4;Further, using welding manner Pre-embedded steel slab 3 and steel deck-plate 4 are spliced.
When implementation, it is as follows:
1. determining the sectional dimension of test beam 7, the ratio of reinforcement of test beam 7 is calculated, determines the strong of longitudinal reinforcement 1 and stirrup 2 Spend grade and diameter, 2 spacing of stirrup, banding steel cage;
2. determining the strength grade of concrete, while in 2 outside point of stirrup of the upper and lower part of the splicing end carriage of precast beam 7 Other pre-embedded steel slab 3, pours prefabricated beam section.
3. test beam is transported to scene after standard curing in 28 days reaches intensity, by test beam 7 and carries out assembly in place.
4. carrying out injecting glue 5 in seam crossing, after intensity reaches requirement, steel deck-plate 4 is placed in 3 outside of pre-embedded steel slab, with weldering Mode is connect to splice pre-embedded steel slab 3 and steel deck-plate 4.
