Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the improvement of the structure of the joint portion of the precast concrete manufacturing method frame.

[0002]

[Prior art and its problems]

 The joint part of the precast concrete method frame is generally formed in a shape that allows the end of the vertical beam method frame and the end of the horizontal beam method frame to be joined together, for example, in the shape of a sword. The rustproof iron wires embedded in the end of the strip are bundled together for integration.

However, in such a joint structure, the law frames are individually connected at each joint by the meshing engagement due to the outer shape of the law frame ends and the wire material that tightly connects the adjacent law frame ends. Since all the legal frameworks are not structurally integrated, deformation and movement of the legal frameworks are likely to occur.

In addition, since the ends of the method frames that are engaged with each other are sharply projected, it is necessary to pay close attention not to damage these parts during transportation. In particular, when the meshed engagement is made by a shape more complicated than the shape of the sword mentioned above, the number of types of law frames increases, and the cost of die production of the law frames increases accordingly.

In view of the above-mentioned problems of the conventional joining structure, the present invention is structurally integrated with the legal frame to achieve an appropriate distribution of the load, and the shape of the end of the legal frame is simple, so that it can be easily transported. The purpose of the present invention is to provide a structure of a joint portion of a precast concrete manufacturing method frame that does not require unnecessary attention.

[0006]

[Means for solving problems]

 In order to solve the above-mentioned problems, the present invention forms a rectangular closed space for joining the ends of the precast concrete vertical beam method frame and the horizontal beam method frame. Within the above-mentioned space for joining, the reinforcing bars that are arranged in a cross shape and that protrude from the end of the vertical beam method frame that is located in the up-down direction, and between the reinforcing bars of the horizontal beam method frame that are located in the left-right direction. Characterized by the fact that they are connected by connecting metal fittings, and the space for joining is filled with a filling material such as mortar and an anchor bolt with an anchor plate that covers the upper surface of the space for joining is driven in. Is.

[0007]

[Action]

 With this structure, it is not necessary to form the method frame into a shape in which the ends are intermeshing with each other, which facilitates manufacturing and handling. The upper and lower vertical beam method frames and the left and right horizontal beam method frames are connected to each other while the reinforcing reinforcement members facing each other are held in tension by connecting metal fittings, and the joint space containing this connecting portion is filled. Since the material is filled and the anchor bolts with anchor plates are driven in, not only the ends of the frame of each joint are integrated individually, but the entire frame is structurally integrated, The uniform distribution of the load prevents the grid deformation of the legal frame from moving.

【Example】

 Hereinafter, the present invention will be described in detail based on illustrated embodiments. FIG. 1 shows a method frame joining portion to which a joining structure according to an embodiment of the present invention is applied, FIG. 2 shows a plan view of the method frame, and FIG. 3 shows a sectional view thereof.

In the figure, reference numerals 1 and 1 ′ are vertical concrete beam frames for concrete, which are molded in a rectangular parallelepiped shape in a factory in advance, and the upper and lower end surfaces thereof are flat and substantially square. Four longitudinal reinforcing beams for vertical beams 2 (2a to 2d) and 2 '(2'a to 2'd) are embedded in the interior along the length direction at intervals, and Screws are formed at the ends of these reinforcing bars 2 and 2'protruding a required length from the upper and lower end surfaces.

Reference numerals 3 and 3 ′ are concrete horizontal beam frames having substantially the same height as the vertical beam frames 1 and 1 ′, and the left and right end surfaces thereof are flat as in the vertical beam frames 1 and 1 ′. It has a substantially square shape. In the lateral beam method frames 3 and 3 ', four lateral beam reinforcing reinforcing bars 4 (4a to 4d) and 4' (4'a to 4'd) are arranged at intervals. The end portions of the reinforcing beams for horizontal beams 4, 4'are more than the end portions of the reinforcing beams for vertical beam 2, 2'when the vertical beam method frames 1, 1'are adjacent to each other in the direction orthogonal to each other. It protrudes to the inner side in the thickness direction, and a screw is formed on the outer circumference in the same manner.

Reference numeral 5 denotes a joining space formed on the slope by the four end portions of the upper and lower vertical beam method frames 1 and 1 ′ and the left and right horizontal beam method frames 4 and 4 ′ which are arranged in a cross shape. The part has a substantially square shape in a plane, and protrudes inward so that the ends of the reinforcing rebars 2 and 2'for vertical beams and the ends of the reinforcing rebars 4 and 4'for horizontal beams cross each other. The end portion of the reinforcing bar 2 protruding from the upper vertical beam method frame 1 has an end portion corresponding to the reinforcing reinforcing bar 2 ′ protruding from the lower vertical beam method frame 1 ′ facing each other in a straight line. Similarly, the end of the reinforcing bar 4 protruding from the left lateral beam method frame 3 is connected to the end of the reinforcing reinforcing bar 4 ′ protruding from the right lateral beam method frame 3 ′. , Those corresponding to each other are connected by a turnbuckle 6.

Reference numeral 7 is a mortar filled in the joining space 5 (see FIG. 3), and 8 is an anchor bolt driven into the joining space 5. The anchor bolt 8 has an anchor plate 9 on the upper portion. The anchor plate 9 preferably has a surface area sufficient to close the upper surface of the joining space 5.

The above-mentioned joint is constructed as follows. First, the vertical beam method frame 1 and the horizontal beam method frame 3 are arranged at predetermined positions on the slope, and a joining space 5 surrounded by the ends of the method frames 1 and 3 is formed at the intersection. The upper and lower vertical beam reinforcing rebars and the left and right horizontal beam reinforcing rebars in the joining space 5 are tightly connected by a turnbuckle 6. As a result, the method frames 1 and 3 are integrated in the longitudinal direction or the lateral direction via the reinforcing reinforcing bars 2 and 4, respectively. As a metal fitting for connecting the reinforcing reinforcing bars 2 and 4, a normal metal fitting such as a coupler may be used in addition to the turnbuckle with adjustable distance.

In this embodiment, the reinforcing beam 4 for the horizontal beam is arranged so as to abut inside the reinforcing bar 2 for the vertical beam in the joining space 5. Therefore, of the four horizontal beam reinforcing reinforcing bars 4a to 4d, the two horizontal beam reinforcing reinforcing bars 4a and 4b located above are positioned above the four vertical beam reinforcing reinforcing bars 2a to 2d. The two reinforcing reinforcing bars for vertical beams 2a, 2b are pressed down from above, and the two reinforcing reinforcing bars for horizontal beams 4c, 4d located below are, on the contrary, the two reinforcing reinforcing bars for vertical beams below. The arrangement is such that 2c and 2d are pressed from above. As a result, the vertical beam reinforcing bar 2 and the horizontal beam reinforcing bar 4 prevent the other legal frame from rising. Of course, even if the positional relationship between the reinforcing rebars 2 for vertical beams and the reinforcing rebars 4 for horizontal beams is reversed from that of this embodiment, the same action is exhibited.

Then, a filler such as mortar 7 or concrete is poured into the joining space 5 and the anchor bolt 8 is driven perpendicularly to the slope. The anchor plate 9 attached to the anchor bolt 8 completely closes the upper surface of the joining space 5. As a result, the vertical beam method frame 1 and the horizontal beam method frame 3 are fixed at the joint, and the respective method frames are structurally integrated in the vertical and horizontal directions.

[0016]

[Effect of device]

 As described above, according to the present invention, the rectangular joining space portion is formed by the opposite ends of the vertical beam method frame located vertically and the opposite ends of the horizontal beam method frame located laterally. In this joining space, the reinforcing bars of the vertical beam frame and the reinforcing beams of the horizontal beam are connected by connecting metal fittings, respectively, and the filling space is filled with an anchor plate. Since the anchor bolts are driven into each other, the vertical beam method frames and the horizontal beam method frames are integrated by the reinforcing bars connected to each other, respectively, and the vertical beam method frame is provided by the filler, the anchor bolts and the anchor plates. And the method frame for horizontal beam is firmly bonded to each other, and all the method frames can be structurally integrated.

Further, according to the present invention, the vertical beam method frame and the horizontal beam method frame are not made to engage with each other by their outer shapes, but the end faces can be formed flat, so that the concrete method frame is manufactured, transported and processed. It facilitates handling such as lifting work on a surface.
