Description

Technical Field

[0001] This utility model relates to the field of composite slab technology, and in particular to a temporary support structure for composite slabs. Background Technology

[0002] Temporary support structures for composite slabs refer to temporary support systems installed during the construction of composite slabs to ensure their stability and safety. These systems are typically used after the composite slabs have been poured and reached a certain strength to prevent the slabs from sinking, deforming, or tilting due to their own weight or external loads. Common temporary support structures include wooden support frames, steel support frames, and prefabricated supports. The selection of appropriate support methods and materials depends on the specific construction conditions and design requirements. After construction is completed, the temporary support structures are removed, and the composite slabs will rely on their own strength and stiffness to bear subsequent loads.

[0003] However, most of the existing temporary support structures for composite slabs are composed of multiple parts, which requires on-site assembly during use, resulting in low overall work efficiency. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a temporary support structure for composite plates.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A temporary support structure for a composite slab includes two first support arms, each top of which is slidably connected to a second support arm. Each of the two second support arms has a top plate on its top and a lifting mechanism for raising and lowering the top plate. Two symmetrical sliding grooves are formed on the surfaces of the two first support arms, and connecting rods are slidably connected inside each groove. Each connecting rod is fixedly connected to one side of a second support arm. The same slip ring is fixedly connected to the surface of the connecting rods away from the second support arm, and the slip ring is slidably connected to the surface of the first support arm. A fixing ring is fixedly connected to the top of each of the two first support arms, and a connecting mechanism for connecting the slip ring is provided on one side of each fixing ring. Second fixing holes are formed on the surfaces of the two second support arms away from the top plate, and support mechanisms for supporting the second support arms are provided inside each of the two second fixing holes. The inclusion of second support arms avoids the need for on-site assembly of components.

[0007] As a further embodiment of this utility model, the lifting mechanism includes a first threaded groove, which is formed on the top of the second support arm. A third support arm is rotatably connected to the top of the second support arm. A second threaded groove is formed on the surface of the third support arm near the first threaded groove. The second threaded groove and the first threaded groove are mutually fitted. The top plate is rotatably connected to the top of the third support arm. A torsion ring is fixedly connected to the surface of the third support arm near the top plate. The top plate can be lifted or lowered by the third support arm.

[0008] As a further embodiment of this utility model, the connecting mechanism includes a first connecting ear, two first connecting ears are fixedly connected to one side of the fixed ring and are symmetrically arranged, an adjusting arm is rotatably connected to the surface of each of the two first connecting ears and is arranged in a cross configuration, and a second connecting ear is rotatably connected to the other end of each of the two adjusting arms, and the two second connecting ears are fixedly connected to one side of the slip ring. By setting the adjusting arms, the two first supporting arms can be connected.

[0009] As a further embodiment of this utility model, the support mechanism includes a support column, which is slidably connected to one side of the first support arm. The surface of the first support arm away from the support column is provided with a plurality of first fixing holes, which are vertically and evenly arranged. The first fixing holes and the second fixing holes are both configured to cooperate with the support column. The second support arm can be supported by the support column.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model adopts a technical solution of using a slip ring to drive the second support arm to move upward, thus avoiding on-site assembly of parts. This effectively solves the problem that most devices are composed of multiple parts, which leads to low overall work efficiency due to the need for on-site assembly during use. A top plate is also installed on the top of the two second support arms, and the top plate cooperates with the second support arms through a third support arm. Since the third and second support arms are connected by a threaded groove, rotating the third support arm can move the top plate upward, thereby enabling a tighter connection between the top plate and the composite plate. Because this device only needs to be opened on-site for use, on-site assembly of parts is avoided, thus improving overall work efficiency. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-4 A temporary support structure for a composite slab includes two first support arms 1, with a second support arm 2 slidably connected to the top of each of the two first support arms 1. A top plate 3 is provided on the top of each of the two second support arms 2, and a lifting mechanism for raising and lowering the top plate 3 is provided on the top of each of the two second support arms 2. Two sliding grooves 104 are symmetrically formed on the surface of each of the two first support arms 1, and a connecting rod 201 is slidably connected inside each of the two sliding grooves 104. Both connecting rods 201 are fixedly connected to one side of each of the two second support arms 2. A slip ring 202 is fixedly connected to the surface of each of the two connecting rods 201 on the side away from the second support arm 2, and the slip ring 202 is slidably connected to the surface of each of the first support arms 1. A fixing ring 101 is fixedly connected to the top of each of the two first support arms 1, and a connecting mechanism for connecting the slip ring 202 is provided on one side of each of the two fixing rings 101. Second fixing holes 204 are formed on the surface of each of the two second support arms 2 on the side away from the top plate 3, and a support mechanism for supporting the second support arm 2 is provided inside each of the two second fixing holes 204. The provision of the second support arms 2 avoids the need for on-site assembly of components.

[0019] Preferably, the lifting mechanism includes a first threaded groove 205, which is formed on the top of the second support arm 2. A third support arm 301 is rotatably connected to the top of the second support arm 2. A second threaded groove 303 is formed on the surface of the third support arm 301 near the first threaded groove 205. The second threaded groove 303 and the first threaded groove 205 are mutually fitted. The threaded grooves allow the second support arm 2 and the third support arm 301 to be connected. The top plate 3 is rotatably connected to the top of the third support arm 301. A torsion ring 302 is fixedly connected to the surface of the third support arm 301 near the top plate 3. The third support arm 301 allows the top plate 3 to be raised or lowered.

[0020] Preferably, the connecting mechanism includes a first connecting ear 102. Both first connecting ears 102 are fixedly connected to one side of the fixing ring 101 and are symmetrically arranged. Adjusting arms 103 are rotatably connected to the surfaces of both first connecting ears 102 and are arranged in a cross configuration. The other end of each of the two adjusting arms 103 is rotatably connected to a second connecting ear 203. Both second connecting ears 203 are fixedly connected to one side of the slip ring 202. By setting the adjusting arms 103, the two first support arms 1 can be connected.

[0021] Preferably, the support mechanism includes a support column 106, which is slidably connected to one side of the first support arm 1. The surface of the first support arm 1 away from the support column 106 is provided with a plurality of first fixing holes 105, which are vertically and evenly arranged. The height of the second support arm 2 can be adjusted by the setting of the first fixing holes 105. The first fixing holes 105 and the second fixing holes 204 are both configured to cooperate with the support column 106. The second support arm 2 can be supported by the setting of the support column 106.

[0022] Working principle: In use, firstly, the two support columns 106 are pulled out from inside the first support arm 1, and then the slip ring 202 is dragged, thereby moving the second support arm 2 upward. Adjusting arms 103 are installed on one side of each of the two slip rings 202, and the adjusting arms 103 are cross-connected. Therefore, when the slip ring 202 moves upward, the angle of the adjusting arms 103 is adjusted accordingly, ensuring that the two first support arms 1 can separate. Multiple first fixing holes 105 are provided on one side of each of the two first support arms 1, and these multiple first fixing holes 105 cooperate with the second fixing holes 204 at the bottom of the second support arm 2. Thus, when the slip ring 202 rises to the designated height, it supports... The column 106 is inserted into the second fixing hole 204 through the corresponding first fixing hole 105, thereby achieving the purpose of supporting and fixing the second support arm 2. A top plate 3 is also installed on the top of the two second support arms 2, and the top plate 3 cooperates with the second support arm 2 through the third support arm 301. Since the third support arm 301 and the second support arm 2 are connected by a threaded groove, the top plate 3 can be moved upward by rotating the third support arm 301, so that the top plate 3 can be more tightly connected with the composite plate. Because this device can be used on site by simply opening it, it can avoid on-site assembly of parts, thereby improving the overall work efficiency.
