Description

Negative bracket connection structure

Technical field

The utility model relates to building structure field more particularly to a kind of negative bracket connection knots connecting for abutment wall with beam Structure.

Background technique

Hydropower Station river formula Factory Concrete side amount is big, working procedure is more and complicated, duration anxiety, construction of hydropower process In, often since electromechanical equipment bid is not in time or due to mechanical and electric equipment installation is slow etc., cause each laminate beam of workshop pour into Degree lag；And workshop abutment wall, since its structure is more single, the concreting rate of climb is very fast；It is easy to appear workshop abutment wall and beam Concrete construction pours the inconsistent problem of progress；If completely equal plate-girders pour corresponding abutment wall again after being formed, construction of hydropower into Degree tends not to meet power generation construction period.To solve the contradiction, positive bracket structure, but sun are generallyd use in previous engineering practice Bracket structure need to occupy workshop inner space, have certain influence to layout of electro-mechanical equipment and operation.

Utility model content

The technical issues of the utility model solves is to provide that one kind can effectively solve workshop abutment wall and beam concrete construction is poured The negative bracket connection structure of the inconsistent problem of progress is built, while without occupying workshop inner space.

The technical scheme adopted by the utility model to solve the technical problem is as follows: negative bracket connection structure, including first pour side Wall pours beam after further including, and is provided with the bracket cavity of indent in abutment wall in described first pour, is embedded in the bracket cavity pre- Doweling, pours beam pouring molding synchronous with the concrete bracket in bracket cavity after described, and after pour the reinforcing bar being arranged in beam It is connect with the pre- doweling.

Further, the width B of the bracket cavity pours the equivalent width of beam with after.

Further, to pour the bottom surface of beam with after concordant for the bottom surface of the bracket cavity.

Further, the height H1 of the oral area of the bracket cavity is higher than the height H2 of inner face；And H2 is poured with after Depth of beam is consistent.

Further, the top surface of the bracket cavity is in be obliquely installed upwards, and it is tilted from inner face to oral area The value range of angle, θ is 30 °~60 °.

Further, the value of θ is 45 °.

Further, formerly pouring the framework of steel reinforcement that abutment wall is provided through bracket cavity

Further, the depth D of bracket cavity is not less than 0.5m.

The beneficial effects of the utility model are: being used for factory by using negative bracket connection structure described in the utility model The connection of room abutment wall and beam, workshop abutment wall can be poured by normal speed, poured beam by after by bracket cavity later and carried out effectively Connection, it is inconsistent to efficiently solve the problems, such as that workshop abutment wall and beam concrete construction pour progress；It may make workshop abutment wall top Crane girder formed as early as possible, bridge machine time of putting into operation shifts to an earlier date significantly, greatly facilitates the electromechanical equipment lifting construction in later period.Moreover, Due to the bracket cavity that the bracket connection structure in the utility model integrally uses indent to be set in abutment wall, bracket cavity Without occupying workshop inner space, be conducive to subsequent to layout of electro-mechanical equipment and operation.

Detailed description of the invention

Fig. 1 is the main view of negative bracket connection structure described in the utility model；

Fig. 2 is the cross-sectional view of Section A-A in Fig. 1；

In the figure, it is marked as first pour abutment wall 1, after pour beam 2, bracket cavity 3, bottom surface 31, inner face 32, top surface 33, it is pre-buried insert Muscle 4, framework of steel reinforcement 5.

Specific embodiment

The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

Firstly, yin bracket connection structure described in the utility model is in tying relative to traditional positive bracket connection by bracket For the setting of part evagination, bracket part in the utility model is that indent is arranged, and after the synchronization in the construction of after-pouring beam It pours to form bracket part；Therefore in order to intuitively understand the connection structure in the utility model, it is called negative bracket connection knot Structure.

As shown in Figures 1 and 2, negative bracket connection structure described in the utility model, including abutment wall 1 is first poured, further include After pour beam 2, be provided with the bracket cavity 3 of indent in abutment wall 1 in described first pour, pre-buried insert be embedded in the bracket cavity 3 Muscle 4, pours the pouring molding synchronous with the concrete bracket in bracket cavity 3 of beam 2 after described, and after pour the reinforcing bar being arranged in beam 2 It is connect with the pre- doweling 4.

Wherein, by pouring the concrete in beam 2 and bracket cavity 3 after synchronous pouring molding, the end that beam 2 can be poured by after is taken It is connected on the bottom surface 31 in bracket cavity 3, the support connection between beam 2 and cast-in-place abutment wall 1 is poured after realizing with this.In addition, passing through Pre-plugged is formerly poured to the reinforcing bar that the pre- doweling 4 in abutment wall 1 is poured with after in beam 2 to connect, is poured after can further improve in this way Beam 2 and first pour the connection structure intensity between abutment wall 1.Without loss of generality, pre- doweling 4 can be poured directly to the steel in beam 2 with after Muscle welding link.

Specifically, the width B for being preferably provided with bracket cavity 3 in the utility model pours beam 2 with after for bracket cavity 3 Equivalent width；The width dimensions of bracket cavity 3 can be minimized in this way, while being poured beam 2 after also ensuring that and first being poured the effective of abutment wall 1 Connection cooperation.

In addition, to pour the bottom surface of beam 2 with after concordant for the bottom surface 31 that bracket cavity 3 is further arranged in the utility model, i.e., after Bottom surface and the bottom surface of the concrete of synchronous pouring molding in bracket cavity 3 for pouring beam 2 are concordant, form part to avoid in junction Mutation structure.

In addition, the height H1 of the oral area of bracket cavity 3 is set above inner end in the utility model for the ease of construction The height H2 in face 32；Simultaneously for inner face 32 height be then set as pouring the height of beam 2 with after it is consistent；It specifically can refer to attached drawing Shown in mark in 2.More specifically, the top surface 33 of settable bracket cavity 3 is in and is obliquely installed upwards from inner face 32 to oral area, And the value range of its tilt angle theta is 30 °~60 °, such as is preferably arranged to 45 °.

In addition, it is generally the case that formerly pour and be provided with corresponding framework of steel reinforcement 5 in abutment wall 1 to improve the knot for first pouring abutment wall 1 Structure intensity.Correspondingly, when formerly pour be provided with framework of steel reinforcement 5 in abutment wall 1 when, can be further by part framework of steel reinforcement 5 from bracket It is passed through in cavity 3；In this way, the subsequent molding concrete bracket of casting concrete in bracket cavity 3 can be further improved and elder generation Pour the connection structure intensity of abutment wall 1.

Without loss of generality, in order to ensure the concrete bracket of pouring molding in bracket cavity 3 can provide enough supports by force Degree, the utility model are preferably provided with the depth D of bracket cavity 3 not less than 0.5m；It is specific then can according to the actual situation, guarantee its Effectively rationally it is arranged in the case where support.Certainly, without loss of generality, the depth of bracket cavity 3, which should not be larger than, first pours side The thickness of wall 1.
