Description

Technical Field

[0001] This utility model relates to the field of load-bearing wall reinforcement technology, specifically to an auxiliary shaping device for load-bearing wall casting reinforcement. Background Technology

[0002] As the main vertical load-bearing components of a building structure, load-bearing walls are of paramount importance in terms of safety and load-bearing capacity. The walls adjacent to a load-bearing wall on either side are called side walls. When a load-bearing wall becomes insufficient in load-bearing capacity due to aging, damage, design changes, or functional alterations (such as openings), it must be reinforced. Enlarging the cross-section (external concrete reinforcement method) is one of the most common and effective methods for reinforcing load-bearing walls. Its core principle is to add a layer of reinforced concrete to the surface of the original wall to share the load.

[0003] In the enlarged cross-section construction method, the shaping plate provides the boundary for the newly poured reinforcement materials (concrete, high-strength grout, polymer mortar, etc.).

[0004] Traditional methods often use temporarily found wooden boards as formwork to seal the pouring area. However, the wall area varies in size, and multiple wooden boards need to be spliced ​​together during use. The gaps between the joints of the multiple wooden boards are relatively large, and during the pouring process, the grout can easily seep out from the gaps between the wooden boards, causing grout leakage. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an auxiliary shaping device for the reinforcement of load-bearing walls, so as to solve the problem in the prior art that, due to the different wall areas, multiple wooden boards need to be spliced ​​together during use, and the gaps between the multiple wooden boards are large. During the pouring process, the grout can easily seep out from the gaps between the wooden boards, causing grout leakage.

[0006] This utility model is achieved through the following technical solution:

[0007] An auxiliary shaping device for reinforcing a load-bearing wall includes a base plate, a connecting plate, and a top plate. The lower side wall of the connecting plate is fixedly connected to a first protrusion that gradually tapers from top to bottom. The upper side wall of the connecting plate is provided with a first groove that gradually tapers from top to bottom. The side wall of the base plate is provided with a second groove that matches the first protrusion. The lower side wall of the top plate is fixedly connected to a second protrusion that matches the first groove.

[0008] Furthermore, a support plate is fixedly connected to the side wall of the base plate, the angle between the base plate and the support plate is a right angle, and the connection between the base plate and the support plate is L-shaped.

[0009] Furthermore, a first side plate is fixedly connected to both sides of the base plate, and the angle between the two first side plates and the base plate is a right angle. The base plate and the two first side plates are connected in a U-shape.

[0010] Furthermore, a second side plate is fixedly connected to both sides of the connecting plate, and the angle between the two second side plates and the connecting plate is a right angle. The connecting plate and the two second side plates are connected in a U-shape.

[0011] Furthermore, the top plate is hinged to both sides with third side plates, and the side wall of the top plate is provided with a third groove that matches the two third side plates. The two third side plates can be rotated into the third groove and connected to the top plate in a straight line. The two third side plates can be rotated to a right angle with the top plate, and the top plate can be connected to the two second side plates in a U-shape.

[0012] Furthermore, the top plate is provided with casting holes.

[0013] Furthermore, the lower sidewalls of the connecting plate and the top plate are fixedly connected with limit blocks, and the upper sidewalls of the bottom plate and the connecting plate are provided with limit grooves that are adapted to the limit blocks.

[0014] Furthermore, the first protrusion, the second protrusion, the first groove, and the second groove are all arc-shaped.

[0015] Furthermore, the first protrusion, the second protrusion, the first groove, and the second groove are all isosceles triangles.

[0016] Furthermore, the first protrusion, the second protrusion, the first groove, and the second groove are all isosceles trapezoids.

[0017] The beneficial effects of this utility model are as follows:

[0018] This auxiliary shaping device for reinforcing load-bearing walls uses a series of tapering sections—a first protrusion, a second protrusion, a first groove, and a second groove—to connect the connecting plate to the top and bottom plates. This reduces the gaps at the joints, decreasing the probability of grout seeping through and causing leakage. The number of connecting plates can be increased between the bottom and top plates, making it suitable for load-bearing walls of varying heights.

[0036] Example 1:

[0037] Please see Figure 1-7 This utility model provides a technical solution: an auxiliary shaping device for reinforcing a load-bearing wall by casting, comprising a base plate 1, a connecting plate 2, and a top plate 3. The lower side wall of the connecting plate 2 is fixedly connected to a first protrusion 4 that gradually tapers from top to bottom. The upper side wall of the connecting plate 2 is provided with a first groove 5 that gradually tapers from top to bottom. The side wall of the base plate 1 is provided with a second groove 7 that matches the first protrusion 4. The lower side wall of the top plate 3 is fixedly connected to a second protrusion 6 that matches the first groove 5.

[0038] A support plate 8 is fixedly connected to the side wall of the base plate 1. The angle between the base plate 1 and the support plate 8 is a right angle, and the connection between the base plate 1 and the support plate 8 is L-shaped.

[0039] The top plate 3 is provided with a pouring hole 13.

[0040] The lower sidewalls of the connecting plate 2 and the top plate 3 are fixedly connected to limit blocks 14, and the upper sidewalls of the bottom plate 1 and the connecting plate 2 are provided with limit grooves 15 that are adapted to the limit blocks 14.

[0041] The first protrusion 4, the second protrusion 6, the first groove 5, and the second groove 7 are all in the shape of an isosceles trapezoid.

[0042] In this design: a support plate 8 is fixedly connected to the side wall of the base plate 1, with the included angle between the base plate 1 and the support plate 8 being a right angle, and the connection between the base plate 1 and the support plate 8 forming an L-shape. This allows it to conform to the base of the load-bearing wall 16 and the ground, providing a bottom support surface and reducing the probability of grout seeping from the base of the wall.

[0043] By creating a pouring hole 13 in the top plate 3, the grout can be injected directly through the pouring hole 13, eliminating the need to create a through hole in the roof for injection.

[0044] By fixing limiting blocks 14 to the lower sidewalls of both the connecting plate 2 and the top plate 3, and by providing limiting grooves 15 on the upper sidewalls of both the bottom plate 1 and the connecting plate 2 to fit the limiting blocks 14, the limiting blocks 14 are inserted into the corresponding limiting grooves 15 during assembly, reducing the gaps between the connecting plate 2 and the top plate 3 and bottom plate 1. Furthermore, the limiting blocks 14 and the corresponding limiting grooves 15 form a vertical anti-misalignment structure.

[0045] By designing the first protrusion 4, the second protrusion 6, the first groove 5, and the second groove 7 as isosceles trapezoids, the grout that has entered the gap between the top plate 3 and the connecting plate 2 or the connecting plate 2 and the bottom plate 1 can flow back along its slope into the reinforced cavity formed by the load-bearing wall 16, the connecting plate 2, the bottom plate 1, and the top plate 3, thus reducing the probability of grout leakage.

[0046] How to use:

[0047] Step 1: Place the support plate 8 horizontally and attach it to the ground, so that the horizontal plane of the base plate 1 is perpendicular to the ground.

[0048] Step 2: Insert the first protrusion 4 on the lower side of the connecting plate 2 into the second groove 7 of the base plate 1;

[0049] Step 3: Insert the second protrusion 6 on the lower side of the top plate 3 into the first groove 5 on the upper side of the connecting plate 2;

[0050] Step 4: Inject the grout through the pouring hole 13 into the reinforced cavity formed by the load-bearing wall 16, the connecting plate 2, the bottom plate 1, and the top plate 3;

[0051] Step 5: After the grout has solidified, remove the top plate 3, connecting plate 2 and bottom plate 1.

[0052] Technical effects:

[0053] Compared to existing technologies, the connecting plate 2 is spliced ​​with the top plate 3 and the bottom plate 1 by gradually tapering from top to bottom using the first protrusion 4, the second protrusion 6, the first groove 5, and the second groove 7. This creates a closed boundary for the pouring cavity during the construction of the load-bearing wall 16 using the enlarged cross-section method. Furthermore, the gaps at the joints between the connecting plate 2 and the top plate 3 and bottom plate 1 are reduced, decreasing the probability of grout seeping out from the gaps at the wooden board joints and reducing the probability of grout leakage. The number of connecting plates 2 can also be increased between the bottom plate 1 and the top plate 3, making it suitable for load-bearing walls 16 of different heights.

[0054] In this embodiment: both sides of the base plate 1 are fixedly connected to a first side plate 9, the angle between the two first side plates 9 and the base plate 1 is a right angle, and the base plate 1 and the two first side plates 9 are connected in a U-shape.

[0055] The connecting plate 2 is fixedly connected to two sides of the second side plate 10. The angle between the two second side plates 10 and the connecting plate 2 is a right angle. The connecting plate 2 and the two second side plates 10 are connected in a U-shape.

[0056] The top plate 3 is hinged to two third side plates 11. The side wall of the top plate 3 is provided with a third groove 12 that is adapted to the two third side plates 11. The two third side plates 11 can be rotated into the third groove 12 and connected to the top plate 3 in a straight line. The two third side plates 11 can be rotated to a right angle with the top plate 3. The top plate 3 can be connected to the two second side plates 10 in a U-shape.

[0057] In this design: First side plates 9 are fixedly connected to both sides of the base plate 1, with the included angle between the two first side plates 9 and the base plate 1 being a right angle. The base plate 1 and the two first side plates 9 are connected in a U-shape. The two first side plates 9 are attached to the wall surfaces of the side walls 17 on both sides of the load-bearing wall 16, which not only enhances the sealing between the base plate 1 and the side walls 17, but also makes the base plate 1 more stable on the ground, reducing the probability of the base plate 1 tipping over.

[0058] The connecting plate 2 is fixedly connected to two second side plates 10 on both sides. The angle between the two second side plates 10 and the connecting plate 2 is a right angle, and the connecting plate 2 and the two second side plates 10 are connected in a U-shape. The two second side plates 10 are attached to the wall surfaces of the side walls 17 on both sides of the load-bearing wall 16, which can not only enhance the sealing between the connecting plate 2 and the side walls 17, but also make the connecting plate 2 more stable on the base plate 1, reducing the probability of the connecting plate 2 tipping over.

[0059] The top plate 3 is hinged to two third side plates 11 on both sides. Third grooves 12, adapted to the two third side plates 11, are formed on the sidewalls of the top plate 3. The two third side plates 11 can rotate into the third grooves 12 and connect with the top plate 3 in a straight line, facilitating the installation of the top plate 3 on the upper side of the connecting plate 2. The two third side plates 11 can rotate until the angle between them and the top plate 3 is a right angle, allowing the top plate 3 to connect with the two second side plates 10 in a U-shape. The two third side plates 11 fit snugly against the sidewalls 17 on both sides of the load-bearing wall 16, enhancing the sealing between the top plate 3 and the sidewalls 17, and making the top plate more stable on the connection, reducing the probability of the top plate 3 tipping over.

[0060] Example 2:

[0061] Please see Figure 8 The difference between this embodiment and Embodiment 1 is that the first protrusion 4, the second protrusion 6, the first groove 5 and the second groove 7 are all arc-shaped.

[0062] In this design, the first protrusion 4, the second protrusion 6, the first groove 5, and the second groove 7 are all designed as arc shapes. Compared to designing them as isosceles trapezoids, this reduces the risk of abrasions to workers caused by the sharp edges of the base plate 1, connecting plate 2, or top plate 3 during handling.

[0063] Example 3:

[0064] Please see Figure 9 The difference between this embodiment and Embodiment 1 is that the first protrusion 4, the second protrusion 6, the first groove 5 and the second groove 7 are all isosceles triangles.

[0065] In this design, the first protrusion 4, the second protrusion 6, the first groove 5, and the second groove 7 are all isosceles triangles. Compared to an isosceles trapezoid, the hypotenuse of an isosceles triangle is longer than that of an isosceles trapezoid at the same height, which can reduce the amount of grout remaining in the gap between the top plate 3 and the connecting plate 2 or between the connecting plate 2 and the bottom plate 1.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
