Description

Technical Field

[0001] The present application relates to the field of formwork engineering materials in building construction, and in particular to a wall column inner corner formwork connection structure. Background Art

[0002] The internal angle is one of the architectural structures. It refers to the recessed corner of the wall, such as the angle between the top surface and the surrounding walls or beams.

[0003] If the internal angle of a wall column is too far off, the concrete must be chiseled and repaired before renovation, resulting in significant waste of materials and labor. Since internal angles are often 90 degrees, the inspection of internal angles requires that the edges of the internal and external angles be perpendicular and parallel to the main structure of the house, and that the corners be straight and square, allowing for minimal or no plastering.

[0004] The existing loose-fitting wall column internal corner formwork has the following problems when setting up and installing: (1) After the edge formwork is connected together with the edge formwork using iron nails and iron wires, the internal corner wood can be nailed together with the two sides of the internal corner formwork within 3.6 meters at the bottom, but it is extremely difficult to be tight at the top, and each time the formwork is removed, the internal corner wood secondary keel must be removed first, and then the internal corner formwork is removed one by one. Although the assembly is simple, it is difficult to ensure the quality of the internal corner structure, and it is highly dependent on the workers' skills, and the assembly efficiency is low; (2) The tightness of the internal corner formwork structure after assembly is low, and because the long wood secondary keel is easy to deform and the edge formwork is easy to be cracked by iron nails, that is, as the number of turnovers increases, the internal corner joints become worse and worse, and the gaps generated during the concrete pouring process become larger and larger, which in turn leads to leakage, causing quality problems and incurring chiseling and repair costs, that is, it is extremely difficult to achieve the effect of no plastering.

[0030] Example 1

[0031] like Figure 1As shown, a wall column internal corner formwork connection structure includes several internal corner formwork structures connected in sequence; the internal corner formwork structure is composed of two internal corner formworks 100 arranged perpendicular to each other, a internal corner secondary purlin 300 arranged at the angle between the two internal corner formworks 100, and at least two internal corner connecting pieces 200 fixed on the two internal corner formworks 100 at the same time.

[0032] like Figure 2 As shown, the internal angle connecting piece 200 is composed of a connecting piece 201, a limiting groove 202 arranged on the connecting piece 201, a limiting piece 203 arranged on the upper side of the connecting piece 201 and adjacent to the limiting groove 202, a fixing piece 204 arranged on the upper side of the connecting piece 201 and with both ends extending to the limiting groove 202, and a pin hole 205 arranged on the connecting piece 201.

[0033] The connecting piece 201 is 1 / 4 circular, and the limiting groove 202 is rectangular; a corner of the limiting groove 202 coincides with the center of the connecting piece 201, and two sides of the limiting groove 202 extending from the corner coincide with two sides of the connecting piece 201 extending from the center of the circle.

[0034] Setting the connecting piece into an arc shape can make its non-fixed side more rounded, which can effectively prevent construction workers from being scratched by sharp edges and corners and reduce the weight of the product.

[0035] The size of the limiting groove 202 matches the internal angle secondary keel 300 .

[0036] The limiting groove matches the size of the internal corner secondary purlin, which can effectively avoid mutual interference between the internal corner secondary purlin and the internal corner connecting piece, ensure their respective use effects, and improve the stability of the accessory assembly.

[0037] The limiting plate 203 and the fixing plate 204 are both perpendicular to the connecting plate 201; there are two limiting plates 203, and the two limiting plates 203 are perpendicular to each other; there are two fixing plates 204, and the two fixing plates 204 are respectively perpendicular to their adjacent limiting plates 203; a plurality of fixing holes are provided on the fixing plate 204.

[0038] The function of the fixing plate is to enable the internal angle connecting plate to be fixed to the internal angle template by screws or nails, which can not only ensure the splicing angle between the internal angle templates spliced together, but also improve the force bearing capacity between the internal angle templates spliced together.

[0039] like Figure 3 As shown, the internal angle secondary keel 300 consists of an L-shaped main body 301 , an L-shaped reinforcement sheet 302 spanning the L-shaped main body 301 , and a plurality of groups of fixing holes 303 arranged on two adjacent surfaces of the L-shaped main body 301 .

[0040] There are two L-shaped reinforcing pieces 302 , and the two L-shaped reinforcing pieces 302 divide the L-shaped body 301 into three sections. The L-shaped reinforcing pieces 302 are fixed to the L-shaped body 301 by welding, and the L-shaped reinforcing pieces 302 and the L-shaped body 301 together form a rectangle.

[0041] The L-shaped body is fixed to the internal angle template by screws or nails passing through the fixing holes. Compared with the square tube method, the L-shaped body can better reduce the overall weight of the structure, which reduces the production and use costs while ensuring the stability of the structure.

[0042] The lower side of the connecting piece 201 located at the end of the internal angle formwork structure is arranged to face outward.

[0043] The purpose of the above-mentioned arrangement is to ensure the tightness of the fixing between the connecting pieces so that no elastic space will appear between the connecting pieces after they are fixed, thereby ensuring the stability of the accessories after assembly.

[0044] The two connecting pieces 201 at the joints of two adjacent internal angle template structures are fixed by a pin that simultaneously passes through the two pin holes 205 and a pin piece that matches the pin.

[0045] The two connecting pieces 201 are located at the junction of the two internal angle template structures, wherein the lower side surface of one connecting piece 201 is 13 mm away from the end edge of the internal angle template 100 fixed by it, and the lower side surface of the other connecting piece 201 exceeds the end edge of the internal angle template 100 fixed by it by 10 mm.

[0046] Since the internal angle formwork is a wooden structure with a certain degree of deformation ability, and there is an extra 3mm gap between the two connecting pieces, when the two connecting pieces are tightly fixed by pins, the contact surface between the internal angle formwork will deform by 3mm, thereby ensuring that there will be no gaps in the product during use, ensuring that there will be no leakage during the concrete pouring process, and ensuring the quality of the final wall column.

[0047] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0048] In addition, the above-mentioned specific embodiments are merely illustrative. Those skilled in the art may devise various solutions based on the disclosure of this utility model, and such solutions fall within the scope of disclosure and the scope of protection of this utility model. Those skilled in the art should understand that the specification and drawings of this utility model are illustrative and do not constitute limitations of the claims. The scope of protection of this utility model is defined by the claims and their equivalents.
