Description

Technical Field

[0001] The utility model relates to the field of concrete component construction, in particular to a device for manufacturing a small concrete pier. Background Art

[0002] In concrete components, small piers are easily overlooked during construction due to their small size, leading to quality problems. The construction location of small piers is usually located below existing construction objects. For example, it is necessary to cast small piers at the lower end of a support frame with a pipe, and conventional molds cannot bypass the pipes and support frames and surround the lower end of the support frame. Therefore, the traditional practice is to directly use solid wood boards, square wood and iron nails to temporarily surround and nail together to make molds. However, this method often causes deformation and damage of the wooden mold, resulting in quality problems such as deformation of the appearance, honeycomb surface, and leakage of slurry during casting of the small pier. In addition, after demoulding, the damaged surface of the wooden mold adheres to the surface of the small pier, resulting in poor visual effects, uncontrollable construction quality, and difficulty in reusing the wooden mold. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a small concrete pier manufacturing device, which will not be affected by existing construction objects when pouring small concrete piers, can quickly carry out construction, and can better ensure construction quality.

[0004] In order to solve the above technical problems, the technical solutions adopted are as follows:

[0005] A device for making a small concrete pier, characterized in that it includes two unfolding components, the unfolding components include two enclosure plates, the front ends of the two enclosure plates are hinged, the rear end of each enclosure plate is provided with a docking piece, and each enclosure plate is made of metal; the device for making the small concrete pier also includes a connecting piece that can connect the two docking pieces.

[0006] When the above-mentioned small concrete pier manufacturing device is used to cast the small concrete pier, the unfolding assembly can be unfolded first to make the two enclosures 90 degrees apart; then the two unfolding assemblies are assembled, and the butt joints at the rear ends of the adjacent enclosures are connected through the connectors, thereby forming a mold with a rectangular casting space; finally, concrete can be cast in the casting space, and the small concrete pier manufacturing device can be removed after the concrete solidifies (first remove the two connectors at the lower diagonal, and then remove the two unfolding assemblies). This small concrete pier manufacturing device can avoid existing construction objects before being combined when in use (for example, when it is necessary to cast a small pier at the lower end of a support frame with a pipeline, the two unfolding assemblies can be combined after being brought close to each other from both sides of the support frame), and it is easy to disassemble and assemble, which is conducive to rapid construction; and the entire manufacturing device is made of metal, and will not be deformed or damaged during construction, and can better control the construction quality, ensure that the small pier after casting has good molding quality, and the manufacturing device can be reused; it can also be folded up for storage when not in use, and does not take up space.

[0007] The front and rear directions are determined according to the positions of the hinged parts of the enclosure panels. In the same unfolding assembly, the two enclosure panels closer to the hinged parts are the front, and the two enclosure panels farther from the hinged parts are the rear.

[0008] In a preferred embodiment, the butt joint is a pin-out hinge, the connecting member is a pin that matches the pin-out hinge, and the pin-out hinge is provided with a pin hole that matches the pin-out. When assembling, the two pin-out hinges only need to be joined together and their pin holes are aligned with each other, and then the pin is inserted into the pin hole to successfully complete the assembly.

[0009] In a further preferred embodiment, a handle is provided at one end of the latch.

[0010] In a further preferred embodiment, the cross-sections of the latch and the pin hole are both regular polygons. With this structure, when the latch is inserted into the pin hole, the two hinges can be fixed, thereby limiting the position of the enclosure plate and preventing the shape of the mold from changing arbitrarily under the action of external forces.

[0011] In another further preferred embodiment, the cross-sections of the latch pin and the pin hole are both circular.

[0012] In a preferred embodiment, in the unfolding assembly, the front ends of the two enclosure plates are hinged by a square hinge.

[0013] In a further preferred embodiment, the maximum expansion angle of the square hinge is 90°. With this structure, the expansion angle of the expansion component can be limited, and when assembling, the expansion component only needs to be expanded to the maximum angle to ensure that the assembled mold is a rectangle.

[0014] In the preferred embodiment, the enclosure plate is made of angle steel. The above-mentioned hinge and square hinge can be fixed on the angle steel by welding. Angle steel is a long steel strip with two sides perpendicular to each other, one side is used to enclose the casting space, and the other side plays a reinforcing role.

[0015] In the preferred embodiment, the docking piece is installed on the rear end of the outer wall of the corresponding enclosure panel. When two enclosure panels in the same unfolding assembly are hinged with a square hinge, the square hinge is also installed on the outer wall of the enclosure panel. In this way, the inner wall of the enclosure panel is a straight wall surface, so the four wall surfaces in the casting space after assembly are also straight wall surfaces. The surface of the cast concrete small pier is flat and smooth, which is more solid and strong. The enclosure panel is easier to remove and is not easy to stick. The docking piece and the square hinge will not be affected by the concrete and can move freely. Usually, before each pouring of concrete, the angle steel can be cleaned and coated with a release agent, which can further improve the quality of the component.

[0016] The beneficial effects of the utility model are that the small concrete pier manufacturing device will not be affected by existing construction objects, can be constructed quickly, and can better ensure the construction quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0022] Example 1

[0023] like Figure 1-4 A device for making a small concrete pier is shown, comprising two unfolding components 1, wherein the unfolding components 1 include two enclosure panels 101, the front ends of the two enclosure panels 101 are hinged, and the rear end of each enclosure panel 101 is provided with a docking piece 2, and each enclosure panel 101 is made of metal; the device for making a small concrete pier also includes a connecting piece 3 that can connect the two docking pieces 2.

[0024] When pouring the concrete pier, the above-mentioned small concrete pier manufacturing device can first unfold the unfolding component 1 to make the two enclosure panels 101 90 degrees apart; then, the two unfolding components 1 are assembled, and the docking components 2 at the rear ends of the adjacent enclosure panels 101 are connected through the connecting components 3, so as to form a mold with a rectangular pouring space; finally, concrete can be poured in the pouring space, and the small concrete pier manufacturing device can be dismantled after the concrete solidifies (first dismantle the two connecting components 3 at the diagonal positions, and then dismantle the two unfolding components 1). This small concrete pier manufacturing device can be used to avoid existing construction objects before being assembled (for example, Figure 4 As shown, when it is necessary to cast a small pier 6 at the lower end of the support frame 5 on which the pipeline 4 is erected, the two unfolding components 1 can be assembled after being brought close to each other from both sides of the support frame 5), which is convenient for disassembly and assembly, and is conducive to rapid construction; and the entire manufacturing device is made of metal, and will not be deformed or damaged during construction, which can better control the construction quality, ensure the good molding quality of the small pier after casting, and the manufacturing device can be reused; it can also be folded up for storage when not in use, and does not take up space.

[0025] The front and rear directions are determined according to the positions of the hinged parts of the enclosure plates 101. In the same unfolding assembly 1, the two enclosure plates 101 closer to the hinged parts are the front, and the two enclosure plates 101 farther from the hinged parts are the rear.

[0026] The butt joint 2 is a pin-out hinge, and the connecting member 3 is a pin that matches the pin-out hinge. The pin-out hinge is provided with a pin hole 201 that matches the pin. When assembling, the two pin-out hinges only need to be joined together and their pin holes 201 are aligned with each other, and then the pin is inserted into the pin hole 201 to successfully complete the assembly.

[0027] A handle 301 is provided at one end of the latch.

[0028] In the unfolding assembly 1 , the front ends of the two enclosure panels 101 are hinged via a square hinge 102 .

[0029] The enclosure plate 101 is made of angle steel. The above-mentioned hinge and square hinge 102 can be fixed on the angle steel by welding. Angle steel is a long steel strip with two sides perpendicular to each other, one side is used to enclose the casting space, and the other side plays a reinforcing role.

[0030] The docking piece 2 is installed on the rear end of the outer wall of the corresponding enclosure panel 101. When the two enclosure panels 101 in the same unfolding assembly 1 are hinged by a square hinge 102, the square hinge 102 is also installed on the outer wall of the enclosure panel 101. In this way, the inner wall of the enclosure panel 101 is a straight wall surface, so the four wall surfaces in the casting space after assembly are also straight wall surfaces, and the surface of the cast concrete small pier is flat and smooth, which is more solid and strong, and the enclosure panel 101 is easier to remove and not easy to stick. The docking piece 2 and the square hinge 102 will not be affected by the concrete and can move freely. Usually, before each pouring of concrete, the angle steel can be cleaned and coated with a release agent, which can further improve the quality of the component.

[0031] Example 2

[0032] The difference between this embodiment and embodiment 1 is that the cross-sections of the latch and the pin hole are both regular polygons. With this structure, when the latch is inserted into the pin hole, the two hinges can be fixed, thereby limiting the position of the enclosure plate and preventing the shape of the mold from changing arbitrarily under the action of external forces.

[0033] Example 3

[0034] The difference between this embodiment and embodiment 1 is that the maximum expansion angle of the square hinge is 90°. With this structure, the expansion angle of the expansion component can be limited. When assembling, the expansion component only needs to be expanded to the maximum angle to ensure that the assembled mold is a rectangle.
