Description

Technical Field

[0001] The invention relates to the technical field of building materials, in particular to a reinforced template angle for a heavy-duty building template frame. Background Art

[0002] Building formwork is the mold shell and support for pouring concrete, which enables concrete structures and components to be formed according to specified positions and geometric dimensions, maintains their correct position, and bears the deadweight of the building formwork and external loads acting on it.

[0003] Aluminum formwork is a newly emerging green construction formwork in the construction industry. It is a new generation of formwork system after wooden formwork and steel formwork. It is light, easy to operate, fast in construction, high in return, environmentally friendly and energy-saving, has many uses, good concrete pouring effect, and is recyclable. It has been widely used in buildings in developed countries such as the United States and Canada, as well as in emerging industrial countries such as Mexico, Brazil, Malaysia, South Korea, and India.

[0004] In aluminum formwork, heavy-duty building formwork consists of a formwork frame and plywood assembled on the formwork frame, and the formwork frame is assembled from aluminum profiles. During transportation and use, the four corners of the formwork frame are particularly prone to deformation due to collisions, resulting in the formwork being unable to be used normally and being discarded. In the prior art, the four corners of the formwork frame are often reinforced by adding angle aluminum. Although this method increases the strength of the corners to a certain extent, since the angle aluminum is inserted into the inner cavity of the aluminum profile, the aluminum profile at the corner is still exposed to the outside and is still prone to deformation in the event of a collision. Therefore, this method cannot fundamentally reinforce the four corners of the formwork frame. Summary of the invention

[0005] The purpose of the present invention is to provide a reinforced template corner for a heavy-duty building template frame to solve the above technical problems.

[0006] To solve the above problems, the technical solution adopted by the present invention is:

[0007] A reinforced template corner for a heavy-duty building template frame, comprising a template corner body in the shape of a regular quadrangular prism as a whole and two groups of plug-in structures for plugging and positioning with template frame profiles; characterized in that: the two groups of plug-in structures are respectively arranged on the front side and right side adjacent to the template corner body, and the angle between them is 90°; each group of plug-in structures comprises an upper plug-in block, a middle plug-in block, a lower plug-in block arranged in sequence from top to bottom along the edge where the front side intersects with the right side, and a long strip plug-in block and an L-shaped plug-in block arranged along the edge where the front side intersects with the left side; the top of the template corner body is provided with a plywood corner guard at a 90° angle, and the plywood corner guard is composed of guard plates on the top of the left side and rear side adjacent to the template corner body; the two groups of plug-in structures, the plywood corner guard and the template corner body are mold-integrated structures.

[0008] Furthermore, a central cavity is provided inside the template corner body; longitudinal long holes are provided in the middle of the front side and the right side; a number of through holes are evenly arranged from top to bottom on the edge surface where the rear side and the left side intersect; the long holes and the through holes are both connected to the central cavity.

[0009] Furthermore, a triangular inclined surface that contracts inwards is provided below the intersecting edge surface between the rear side surface and the left side surface of the template corner body, and a trapezoidal inclined surface that contracts inwards is provided below the rear side surface and the left side surface corresponding to both sides of the triangular inclined surface.

[0010] Furthermore, grooves with arc-shaped cross-sections are respectively provided between the top surface of the template corner body and the guard plates at the top of the left side surface and the rear side surface.

[0011] Furthermore, the front side surface and the right side surface of the template corner body are respectively provided with outwardly protruding bosses at the positions corresponding to the upper plug-in block, the middle plug-in block, the lower plug-in block, the long plug-in block and the L-shaped plug-in block, and the upper plug-in block, the middle plug-in block, the lower plug-in block, the long plug-in block and the L-shaped plug-in block are respectively arranged on their corresponding bosses.

[0012] Beneficial effects: Compared with the prior art, the present invention has a simple structure and is easy to cast. It can fundamentally reinforce the corners of heavy-duty building formwork frames, improve the collision resistance of the four corners of the formwork frame, and extend the service life of the formwork frame. At the same time, the triangular slope and trapezoidal slope structure design of the lower part of the formwork corner body that is contracted inward greatly facilitates the disassembly of the formwork during use.

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Example

[0026] Reference Figure 1-Figure 8 The reinforced template corner for heavy-duty building template frame described in this embodiment is integrally cast and includes a template corner body in the shape of a regular quadrangular prism and two sets of plug-in structures for plugging and positioning with the template frame profile. The two sets of plug-in structures are respectively arranged on the front side surface 5 and the right side surface 18 adjacent to the template corner body, and the angle between them is 90°.

[0027] Each set of plug-in structures includes an upper plug-in block 9, a middle plug-in block 10, a lower plug-in block 11 arranged in sequence from top to bottom along the edge where the front side surface 5 intersects with the right side surface 18, and a long plug-in block 4 and an L-shaped plug-in block 1 arranged along the edge where the front side surface 5 intersects with the left side surface 17. The front side surface 5 and the right side surface 18 of the template corner body are provided with outwardly protruding bosses 2 at the positions corresponding to the upper plug-in block 9, the middle plug-in block 10, the lower plug-in block 11, the long plug-in block 4, and the L-shaped plug-in block 1, respectively, and the upper plug-in block 9, the middle plug-in block 10, the lower plug-in block 11, the long plug-in block 4, and the L-shaped plug-in block 1 are respectively arranged on their corresponding bosses 2.

[0028] The top of the template corner body is provided with a 90° plywood corner guard, which is composed of a guard plate 7 on the top of the left side 17 and the rear side 12 adjacent to the template corner body. A groove 6 with an arc-shaped cross section is provided between the top surface 8 of the template corner body and the guard plate 7 on the top of the left side 17 and the rear side 12.

[0029] The two sets of plug-in structures, the plywood corner guard and the template corner body are integrally formed by the mold.

[0030] A central cavity 19 is provided inside the template corner body; longitudinal elongated holes 3 are provided in the middle of the front side surface 5 and the right side surface 18; a plurality of through holes 14 are evenly arranged from top to bottom on the edge surface 13 where the rear side surface 12 and the left side surface 17 intersect; the elongated holes 3 and the through holes 14 are both connected to the central cavity 19.

[0031] Reference Figure 9-11 When the reinforced template corner of the present invention is used to assemble a heavy-duty building template frame, two sets of plug-in structures are respectively inserted into the inner cavity of the frame profile, wherein: the upper plug-in block 9 is inserted into the corner between the upper front side A4 and the top side A3 of the frame profile; the middle plug-in block 10 is inserted into the inner side of the middle front side A5 of the frame profile; the lower plug-in block 11 is inserted into the corner between the lower front side A6 and the bottom side A7; the long strip plug-in block 4 is inserted into the inner side of the rear side A1; the L-shaped plug-in block 1 is inserted into the corner between the rear side A1 and the bottom side A7. After the insertion and positioning is completed, the reinforced template corner is welded to the frame profile, and the plywood corner guard 7 is connected to the plywood baffle A2 of the frame profile. Each set of plug-in structures is provided with each plug-in block and the frame profile for internal and external dual positioning, and the connection between them is firm. After assembly, the template angle body is exposed to the outside as the corner of the heavy-duty building template frame. Cast template angles are used instead of profiles as the corners of the template frame, which are stronger and more resistant to collision. This effectively solves the problem of deformation of the four corners of the heavy-duty building template frame due to collision and extends the service life of the heavy-duty building template frame.

[0032] A triangular slope 15 that is contracted and tilted inwards is provided below the intersecting edges between the rear side 12 and the left side 17 of the template angle body, and a trapezoidal slope 16 that is contracted and tilted inwards is provided below the rear side 12 and the left side 17 corresponding to the two sides of the triangular slope. When in use, after four heavy-duty building templates are gathered together, a conical space is formed between the triangular slopes and the trapezoidal slopes that are contracted and tilted inwards at the bottom of the template angle bodies of the four adjacent reinforced template angles, which facilitates the removal of the template.

[0033] The present invention has a simple structure and is easy to cast. It can fundamentally reinforce the corners of heavy-duty building formwork frames, improve the collision resistance of the four corners of the formwork frame, and extend the service life of the formwork frame. At the same time, the triangular slope and trapezoidal slope structure design of the lower part of the formwork corner body that is contracted and tilted inward greatly facilitates the disassembly of the formwork during use.

[0034] The above are only implementation modes of the present invention, and are not intended to limit the patent scope of the present invention. On the other hand, any equivalent structure made using the contents of the specification and drawings of the present invention, directly or indirectly used in other related technical fields, are also within the patent protection scope of the present invention.
