Abstract
The invention discloses the assembled connecting nodes of a kind of combination beam and prefabricated board, including Prefabricated combined beam, prefabricated board, cast-in-place concrete layer；Reserved fluted on prefabricated board, groove offers bolt hole, and through-hole corresponding with the bolt hole on prefabricated board is equally reserved on Prefabricated combined beam；Split bolt passes through the through-hole on Prefabricated combined beam and prefabricated board to stretch into the groove of prefabricated board, and both ends apply prestressing force and tense, the casting concrete in prefabricated board groove, you can the assembled connection realizeing combination between beam and prefabricated board.The present invention enhances compared to its shear resistance of traditional assembling type node, and textural association effect is promoted, and node reliability increases.
Description
Technical field
The present invention relates to a kind of assembled architecture, the assembled connecting node of especially a kind of combination beam and prefabricated board.
Background technology
Big heat, country support development assembled architecture to assembled architecture energetically at present.Traditional part outsourcing combination beam needs
Vertical muscle is configured outside shaped steel and forms steel reinforcement cage with stirrup, and construction is complicated, in addition, it is desirable in the junction of precast beam and prefabricated board
Increase weldering peg, welding procedure is difficult, and complexity is unfavorable for assembled architecture assembly.And the integral strength for combination beam and shearing resistance
Ability weld stud is inadequate.
Invention content
Goal of the invention：The invention discloses the assembled connecting nodes of a kind of combination beam and prefabricated board, can be improved to coagulation
The effect of restraint of soil saves the configuration of vertical muscle and steel reinforcement cage, and need not increase weldering peg again in junction, and it is difficult to reduce construction
Degree, the combined effect of lift structure improve the performance of fabricated construction.
Invention content：A kind of assembled connecting node of combination beam and prefabricated board, including Prefabricated combined beam and prefabricated board, in advance
Making sheet is equipped with cast-in-place concrete groove, and bolt hole, Prefabricated combined beam are offered on the prefabricated board of cast-in-place concrete groove
On bolt hole and prefabricated board on bolt hole correspond；Split bolt passes through the spiral shell on Prefabricated combined beam and prefabricated board
Bolt throughhole stretches into the cast-in-place concrete layer in cast-in-place concrete groove.
Wherein, Prefabricated combined beam includes shaped steel and concrete, and shaped steel includes beam web and the beam wing positioned at beam web both sides
Prefabricated board setting is close in edge, the side that Prefabricated combined beam is equipped with flange of beam, and it is cast-in-place that split bolt passes through the flange of beam of both sides to stretch into
Concrete layer.
Advantageous effect：Present invention assembly is simple, and shear resistance relative to traditional combination beam assembling type node significantly
It improves, assembly method of the invention improves the combined effect of structure, and before reducing weakening Prefabricated composite beam strength to the greatest extent
It puts, realizes the connection of Prefabricated combined beam and prefabricated plate node.Meanwhile assembling type node connecting method is simplified, it is promoted pre-
System combination beam strength, thus improve fabricated performance.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is displacement-load curve figure that shaped steel is combined progress load test to obtain with ordinary concrete specimens；
Fig. 3 is the test specimen manuscript that split bolt is arranged not in shaped steel；
Fig. 4 is a test specimen manuscript when split bolt being arranged in shaped steel；
Fig. 5 is test specimen manuscript when two split bolts being arranged in shaped steel.
Specific implementation mode
As shown in Figure 1, the assembled connecting node of a kind of combination beam and prefabricated board, including Prefabricated combined beam 1 and prefabricated board
6, Prefabricated combined beam 1 includes shaped steel and concrete, and shaped steel includes beam web 4 and the flange of beam 2 positioned at beam web both sides, prefabricated group
It closes side of the beam 1 equipped with flange of beam and is close to the setting of prefabricated board 6, prefabricated board 6 is equipped with cast-in-place concrete groove, and cast-in-place concrete is recessed
Bolt hole is offered on prefabricated board 6 at slot, the bolt hole on Prefabricated combined beam 1 and the bolt hole one on prefabricated board 6
One corresponds to；Split bolt 3 passes through the bolt hole on Prefabricated combined beam 1 and prefabricated board 6 to stretch into showing in cast-in-place concrete groove
Pouring concrete layer 5, split bolt 3 are arranged relative to 4 Parallel Symmetric of beam web.
As shown in Figure 2-5, shaped steel is combined with ordinary concrete specimens and carries out displacement-loading test, wherein：Shaped steel is long
600mm, concreting length 500mm, effective binding length 500mm, concrete design strength C30 are spent, bond-slip is surveyed
Examination position is web+inside edge of a wing.
From figure 2 it can be seen that not plus when split bolt, displacement reaches 1.94mm, and after load 17.2kN, load is just opened
Begin to decline, residual strength 12.71kN；The displacement of a split bolt has been added to reach 9.76mm, after load 91.15kN, load
It begins to decline, remained load 52.11kN；The displacement of two split bolts has been added to reach 10.13mm, after load 127.2kN, lotus
Load is begun to decline, remained load 76.23kN.Pull rod spacing is 250mm.
Therefore from the foregoing, it will be observed that setting one split bolt, ultimate load is improved from 17.2kN to 91.15kN, will be remaining
Load is improved from 12.71kN to 52.11kN；Be arranged two split bolts, by ultimate load from 17.2kN improve to
127.2kN improves remained load to 76.23kN from 12.71kN.
It can be seen that in fabricated construction by above-mentioned experiment, selection uses split bolt connection combination beam and prefabricated
Plate replaces traditional fabricated construction to connect, and split bolt both can effectively improve the shear resistance of structure, improve structure
Combined effect.
