Description

Technical Field

[0001] The invention relates to the technical field of building construction tools, and in particular to a template clamping device for processing cast-in-place concrete rafters. Background Art

[0002] In cast-in-place concrete antique buildings, the eaves rafters are made of wooden components nailed back on the cast-in-place concrete slabs. Although this gives the material a texture, there is a saying that "the protruding rafters rot first". Over time, the wooden rafters begin to rot. In order to better solve this problem, the cast-in-place form is adopted, which can not only reduce the weight of the eaves board and ensure the appearance, but also solve the problem of not rotting easily.

[0003] To solve the problem of "the protruding rafters rot first", the original wooden rafters are completely exposed to the air and will rot over time, but by pouring them together with the concrete roof panels, the concrete rafters are like small beams that support the cast-in-place roof, reducing the thickness of the panels and solving the trouble of always having to replace wooden rafters.

[0004] The rafters of some buildings are constructed in this form of reinforced concrete. During roof construction, the formwork is supported in a concave and convex shape, the upper steel bars of the beam are combined with the upper steel bars of the slab, and the S-shaped stirrups hook the upper and lower steel bars. Some clamps are needed to fix and clamp the formwork. The existing clamps are all fixed through an integrated die groove, and the structure cannot be adjusted. In addition, the fixing structure between the beam and the beam is not tight in the later stage. Summary of the invention

[0005] Based on the technical problems existing in the background technology, the present invention proposes a template clamping device for processing cast-in-place concrete rafters.

[0006] The present invention proposes a clamping device for processing templates for cast-in-place concrete rafters, comprising two clamps of the same specifications, inner walls of opposite sides of the two clamps are provided with inner templates, and a clamping plate is provided between the bottom ends of the inner templates, an inner rafter hole mold is fixedly connected between the two clamps, and a locking rod is fixedly connected to the inner wall of the bottom end of the inner rafter hole mold, the inner rafter hole mold is fixedly connected between the locking rod and the clamping plate, the bottom ends of the clamps on both sides are vertically fixedly connected with a through rod, and the end of the through rod is connected with a locking head.

[0007] As a further solution of the present invention, a through hole is opened in the middle of the side of the clamping plate, and a rod sleeve is inserted into the inner wall of the through hole, and the outer wall of the locking rod is inserted into the inner wall of the rod sleeve.

[0008] As a further solution of the present invention, the inner rafter hole mold includes a groove plate and a hollow rod, and the hollow rod is vertically connected to the middle part of the top outer wall of the groove plate.

[0009] As a further solution of the present invention, a groove is provided on the inner edge of the top end of the hollow rod, and a sealing head is clamped on the outer wall of the top end of the locking rod, and the outer edge of the bottom end of the sealing head is clamped on the inner wall of the groove.

[0010] As a further solution of the present invention, a tenon is provided in the middle of the outer wall at one end of the splint, and a mortise hole is opened in the middle of the outer wall at the other end of the splint.

[0011] As a further solution of the present invention, it also includes a base plate, wherein both outer walls of the base plate are provided with clamps, and the inner wall of the bottom end of the inner template is provided with locking holes, and the base plate forms a clamping fit with the inner template through the clamps and the locking holes.

[0012] As a further solution of the present invention, a backing plate is clamped between the outer wall of the bottom end of the clamp head and the connection between the locking hole, and the backing plate has a wedge-shaped structure.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The template clamping device is closed by the two side plywood, and is set according to the concave and convex structure between the inner template and the card plate. Tenons and mortise holes are provided at both ends to form a stable mortise and tenon connection structure. The angle can be combined and adjusted to form a longer pouring rafter, and the one-piece molding effect is better;

[0015] 2. The template clamping device is provided with an inner rafter hole mold, which can fix the stability between the splint and the internal template structure before pouring, and form the connection perforations after pouring, so as to facilitate the subsequent expansion screws to be brought into the vertical connection between the beam and the rafter, thereby improving the subsequent connection stability;

[0016] 3. The pad structure of the inner rafter hole mold in this template clamping device is a groove type, and the connection surface with the beam is an arc structure, which has a larger contact surface with the circular beam, thereby improving the overall vertical stability and fit.
