Abstract

The utility model discloses a kind of cast-in-place secondary beam T-shaped floor, it is the floor being prefabricated into by armored concrete, floor includes floor plates and girder, girder is located in the middle part of floor plates, floor periphery is provided with protruding bar, and protruding bar is divided into girder protruding bar and floor plates protruding bar, wherein, the girder protruding bar and floor plates protruding bar at girder both ends are bending structure, and girder both ends form a fixed connection with cast-in-place secondary beam.Using the cast-in-place secondary beam T-shaped floor of the utility model, the secondary beam at girder both ends is cast-in-place structural on floor, has both alleviated the weight of floor, convenient lifting, and and can ensures the continuity of major structure of construction, makes agent structure stability good；Compared with existing laminated floor slab technology, there is the advantages that more preferable globality and shock resistance, cast-in-place concrete amount is few and saves material.

Description

A kind of cast-in-place secondary beam T-shaped floor

Technical field

A kind of assembled architecture component technology field is the utility model is related to, specifically a kind of cast-in-place secondary beam T-shaped floor.

Background technology

Assembled architecture component technology mostly separates the prefabricated pattern assembled again using laminated floor slab and beam at present, folds Close a kind of structure type that floor is prefabricated and cast-in-place concrete is combined.Prefabricated stacking floor and top cast-in-place concrete layer knot Synthesize an entirety, cooperation.The assembling of Prefabricated stacking floor and beam has both complicated assemblings, globality and shock resistance Difference, the shortcomings of connection binding site quality testing of both new-old concretes is difficult and cast-in-place concrete amount is big.In the prior art Also have floor and beam prefabricated floor together, prefabricated another block block is spliced together for floor middle girder and secondary beam, its beam it is disconnected Socket part position is excessive and quality of connection is difficult to ensure that, makes agent structure stability poor.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of cast-in-place secondary beam T-shaped floor, existing prefabricated to overcome Laminated floor slab and beam assembling are complicated, and globality and shock resistance are poor, and conjunction old and new concret location detection is difficult, cast-in-place concrete Amount is big, and existing floor middle girder and secondary beam together prefabricated agent structure stability difference the shortcomings of.

Technical scheme is used by the utility model solves its technical problem：A kind of cast-in-place secondary beam T-shaped floor, it be by The floor that armored concrete is prefabricated into, floor include floor plates and girder, and girder is located in the middle part of floor plates, and floor periphery is provided with outer Stretch reinforcing bar, protruding bar is divided into girder protruding bar and floor plates protruding bar, wherein, the girder protruding bar at girder both ends and Floor plates protruding bar is bending structure, and girder both ends form a fixed connection with cast-in-place secondary beam.

Using the cast-in-place secondary beam T-shaped floor of the utility model, floor and girder can be with integral prefabricated, to greatest extent close to existing There is Building technology specification, greatly ensure the quality of assembled architecture；The secondary beam at girder both ends is cast-in-place structural on floor, is both subtracted The light weight of floor, convenient lifting, and can ensure the continuity of major structure of construction, make agent structure stability good；Floor The girder protruding bar and floor plates protruding bar at upper girder both ends are bending structure, can form firm connection with secondary beam steel； Compared with laminated floor slab technology, there is the advantages that more preferable globality and shock resistance, cast-in-place concrete amount is few and saves material.

Embodiment

The structure of the cast-in-place secondary beam T-shaped floor of the utility model is further described below in conjunction with the accompanying drawings：

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the cast-in-place secondary beam T-shaped floor of the utility model is prefabricated into by armored concrete Floor, floor includes floor plates 1 and girder 2, and girder 2 is located at the middle part of floor plates 1, and floor periphery is provided with protruding bar, overhanging Reinforcing bar is divided into girder protruding bar 3, floor plates protruding bar 4 and floor plates protruding bar 5, wherein, outside the girder at the both ends of girder 2 It is bending structure to stretch reinforcing bar 3 and floor plates protruding bar 4, and the both ends of girder 2 form a fixed connection with cast-in-place secondary beam.

The cast-in-place T-shaped floor size of the utility model is determined by building demand, as cast-in-place T-shaped floor is divided into A and B two in Fig. 1 Floor kind of different sizes, by cast-in-place secondary beam C-shaped into being fixedly connected between floor A and floor B.During installation, floor branch is first installed Support member, lift floor A and floor B successively to the top of form bracing part, to adjust during lifting floor direction and floor it Between leave installation seam；After the completion of floor lifting, the installation form at floor seam；Carry out the cloth of cast-in-place secondary beam C reinforcing bars Cloth muscle at muscle and floor seam D, floor plates protruding bar 5 between floor is formed a fixed connection by overlap joint at floor seam D, To make bending of time beam steel through the girder protruding bar 3 and floor plates protruding bar 4 at the both ends of floor girder 2 during secondary beam cloth muscle Structure；The cast-in-place concrete at cast-in-place secondary beam C and floor seam D again；Form bracing part and seam crossing are removed after the completion of to be onstructed Template can be completed to construct.

Using the utility model, floor and girder can with integral prefabricated, to greatest extent close to existing building technical specification, Greatly ensure the quality of assembled architecture；The secondary beam at girder both ends is cast-in-place structural on floor, has both alleviated the weight of floor, Convenient lifting, and can ensure the continuity of major structure of construction, make agent structure stability good；The girder at girder both ends on floor Protruding bar and floor plates protruding bar are bending structure, and firm connection can be formed with secondary beam steel, improve anti-seismic performance.
