Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a novel reinforcement-free line-laying hole shaping template. Background Art

[0002] During layout in multi-story and high-rise construction, it is often necessary to set up layout holes for the vertical transfer of control points within the three-level control network. Currently, layer boards are processed into a funnel-shaped box with a lower opening measuring 150*150mm and an upper opening measuring 200*200mm. After use, the layout holes need to be roughened and reinforced with steel bars. The layout holes made with layer boards have a low turnover rate, and the sizes and dimensions of the cast shapes vary, resulting in poor results. The biggest problem is that rebar must be planted later, and its firmness cannot be guaranteed. This not only increases construction costs but also cannot guarantee construction quality. Furthermore, if the layout holes are not covered during the later demolding process, there is a risk of material falling, which may even cause personal injury. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a novel rebar-free wire-laying hole shaping template.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] A new type of fixed-shape template for laying out lines without rebar embedding comprises a template box, which has no top plate and bottom plate. Vertical rebar grooves are opened at the same position on the bottom walls on opposite sides of the template box. The lower ends of the rebar grooves are connected to the outside world. The length of the rebar grooves is the same as the thickness of the casting plate, and the width matches the diameter of the reserved rebar. Each rebar groove is equipped with a slurry guard plate, which comprises a slurry guard main plate. Several slurry guard plate slides are opened horizontally on the slurry guard main plate at the positions corresponding to the reserved rebar. One end of the slurry guard plate slide is connected to the outside world, and the width of the slurry guard plate slide matches the diameter of the reserved rebar.

[0006] The template box is welded with galvanized steel plates that are larger at the top and smaller at the bottom.

[0007] A handle is fixed on the top of the template box.

[0008] The end of the slurry guard slideway away from the end communicating with the outside world is provided with a fixing bolt, and the fixing bolt can fix the slurry guard to the reinforcement groove on the inner wall of the template box.

[0009] The beneficial effects of the utility model are:

[0010] The wire-hole shaping template provided by this utility model produces wire-holes of uniform size and shape, ensuring standardized shaping and eliminating the need for rebar planting in the later stages, saving steel. After use, a wire-hole cover plate can be installed for protection. The cover plate can be fitted with a lock, with the key kept by the project manager, to avoid the risk of material falling from the wire-hole. Furthermore, this utility model has a simple structure, is easy to manufacture and process, and is convenient and simple to install and disassemble.

[0017] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0018] See Figure 1-5 , the utility model provides a technical solution:

[0019] A new type of fixed-shape template for laying out holes without rebar embedding, comprising a template box 1, which is larger at the top and smaller at the bottom and is funnel-shaped, without a top plate and a bottom plate. Vertical rebar grooves 3 are opened at the same position on the bottom walls on opposite sides of the template box 1, and the lower ends of the rebar grooves 3 are connected to the outside world. The length of the rebar grooves 3 is the same as the thickness of the casting plate, and the width matches the diameter of the reserved rebar 4. Each rebar groove 3 is equipped with a slurry retaining plate 5, and a handle 2 is welded to the top of the template box 1.

[0020] The slurry guard 5 includes a slurry guard main plate 51, on which a slurry guard slide 53 is transversely opened at the position corresponding to the reserved steel bar 4. One end of the slurry guard slide 53 is connected to the outside world, and the other end is provided with a fixing bolt 52. The fixing bolt 52 can fix the slurry guard 5 to the reinforcement groove 3 on the inner wall of the template box 1. The width of the slurry guard slide 53 matches the diameter of the reserved steel bar 4. The number of slurry guard slides 53 can be set according to the number of reserved steel bars 4. In this embodiment, two slurry guard slides 53 are provided.

[0021] After the wire-paying hole 8 is formed, a cover plate 6 is connected to the movable shutter on the top of the wire-paying hole 8 to prevent casualties caused by falling materials. A lock 7 is installed on the other side of the cover plate 6, and the wire-paying hole 8 is locked when not in use.

[0022] As a specific embodiment, the template box 1 uses a trapezoidal steel plate with a wall thickness of 2.5mm, a short side length of 150mm, a long side of 200mm, and a height of 250mm. This steel plate is welded into a prism shape as the template box 1, and two handles 2 are welded on the top of the two opposite steel plates. Each steel plate needs to be opened from the center of the short side to form a reinforcement groove 3 with a width of 8mm and a length relative to the thickness of the casting plate, which is used to embed the embedded steel bars 4 at the wire holes 8; a slurry plate slide 53 with a width of 8mm and a length of 20mm is opened horizontally at the position of the slurry plate 5 corresponding to the embedded steel bars 4. The position of the slurry plate 5 corresponding to the embedded steel bars 4 can be moved horizontally and blocked by the slurry plate slide 53, so as to seal the vertical reinforcement groove 3 tightly and prevent slurry from leaking. The specifications of the slurry plate 5 are 20*150*2.0mm, and the fixing bolts 52 fix the slurry plate 5 to the inner wall of the template box 1. The cover plate 6 is made of a 300*300*2.0mm steel plate, with a yellow-black warning paint on the surface. One side is connected to the movable shutter, and a lock 7 is installed on the other side for locking management when not in use.

[0023] How to use the wire hole shaping template:

[0024] Place the reinforcement groove 3 in correspondence with the reserved steel bar 4 and put the template box 1 into the reserved hole from top to bottom. Inside the template box 1, clamp the slurry blocking plate slide 53 of the slurry blocking plate 5 on the reserved steel bar 4, push the slurry blocking main plate 51 to block the reinforcement groove 3, and after blocking, use the fixing bolts 52 to fix the slurry blocking plate 5 on the inner wall of the template box 1 to stabilize the blocking effect. After the external casting is formed, remove the slurry blocking plate 5 and tap the template box 1 from bottom to top to remove it. The formed wire-laying hole 8 is protected by a cover plate 6, which is fixed to the concrete floor with bolts and a lock 7 is hung and kept by a dedicated person.

[0025] The utility model has the advantages of simple structure, easy manufacture and processing, wide material sources, can be manufactured on construction sites, and is more practical.

[0026] It is suitable for the layout hole template for vertically upward transmission of control points of multi-story and high-rise three-level control networks; it can also be used to reserve temporary holes in cast-in-place slabs for transferring materials or other purposes. The size of the reserved holes should not be too large.
