Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a formwork support frame for building construction. Background Technology

[0002] Formwork scaffolding is a temporary structure widely used in construction. It is erected to ensure the accuracy of the shape, size, and spatial position of the formwork, and to bear the weight of the formwork, freshly poured concrete, and construction loads. Disc-lock steel pipe formwork scaffolding is a new type of formwork scaffolding system. The nodes are connected by discs, which has the advantages of high structural strength, good stability, and fast installation speed.

[0003] In the current technology for pouring concrete for high-rise buildings, the disc-lock steel pipe formwork supports the concrete by having the top of the steel pipe contact the lower surface of the formwork (the floor level of a high-rise building is formed by concrete pouring and supported by the formwork). However, the contact area between the top of the steel pipe and the disc-lock steel pipe formwork is small, resulting in localized stress concentration. This can easily lead to significant deformation of the formwork at the contact point, affecting the quality of the concrete forming. Therefore, a technical measure is proposed to address the problem of the small contact area between the top of the steel pipe and the disc-lock steel pipe formwork, resulting in localized stress concentration and significant deformation of the formwork at the contact point, thus hindering the improvement of concrete forming quality. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a formwork support for building construction, which aims to solve the problems that the contact area between the top of the steel pipe and the disc-type steel pipe formwork support is small, the local stress is concentrated, and the formwork is prone to large deformation at the contact point, resulting in the need to improve the quality of concrete forming.

[0006] (2) Technical solution

[0007] To address the aforementioned technical problems, this utility model provides a formwork support frame for building construction, comprising a base plate and an adjustable support assembly. A bottom tube is installed at the middle position of the upper surface of the base plate, and the upper end of the bottom tube is threaded. A middle tube is movably installed at the upper end of the bottom tube via the same thread. The adjustable support assembly is movably installed on the top of the middle tube via the same thread. A disc is fixedly fitted on the top of the bottom tube and the middle tube. Thanks to the adjustable support assembly, the contact area with the lower surface of the formwork is increased, preventing localized stress concentration on the formwork and thus avoiding large deformation of the formwork at the contact points, ensuring the quality of concrete forming. The threaded connection between the rotating ring and the top rod has self-locking properties (and the denser the thread, the greater the friction and the better the self-locking properties). Furthermore, the cooperation of the locking teeth and the grooves fixes and limits the vertical rod, thereby ensuring that the support plate will not slide downwards under stress, guaranteeing the pouring quality and improving practicality.

[0008] Furthermore, multiple sets of inclined plates are installed on the upper surface of the base plate.

[0009] Furthermore, the disc is slidably threaded with bolts, and the bolts are threadedly connected to a crossbar, which is connected to the disc via bolts.

[0010] Furthermore, the adjustable support assembly includes a top rod with a threaded lower part. The bottom of the top rod is movably connected to the threaded middle pipe. A limiting plate is sleeved on the lower outer side of the top rod. A thread is opened on the upper outer side of the top rod, and the thread is above the limiting plate. A rotating ring is threadedly connected to the top rod. Two sets of symmetrically distributed rotating rods are installed on the outside of the rotating ring.

[0011] Furthermore, a slip ring is slidably sleeved on the outside of the top rod, the slip ring is above the rotating ring, and two sets of symmetrically distributed push rods are installed on the upper surface of the slip ring, with a support plate installed on the top of the push rod.

[0012] Furthermore, a vertical rod is installed at the middle position of the lower surface of the support plate, the vertical rod is slidably adapted to the top rod, and the side of the vertical rod is provided with a toothed groove.

[0013] Furthermore, an mounting plate is installed on the upper surface of the top rod. The mounting plate is L-shaped and threaded with a screw. The screw is connected to a knob. The end of the screw away from the knob is rotatably connected to a stop plate. Two sets of symmetrically distributed springs are installed on the side of the stop plate. The other end of the springs is installed on the side of the mounting plate. The side of the stop plate away from the screw has a locking tooth that matches the tooth groove.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model, through the setting of the intermediate tube, allows for flexible adjustment of the height of the formwork support according to the floor height, thereby improving its practicality.

[0017] The adjustable support components increase the contact area with the lower surface of the template, preventing localized stress concentration and thus avoiding significant deformation at the contact points, ensuring concrete molding quality. The threaded connection between the swivel and the top rod provides self-locking (the denser the thread, the greater the friction and the better the self-locking). The engagement of the locking teeth and grooves fixes and limits the vertical rod, preventing the support plate from sliding downwards under load, ensuring pouring quality and improving practicality. The top rod is connected to the upper part of the intermediate pipe, and then rotating the swivel moves the support plate upwards, which in turn moves the vertical rod upwards. The support plate then contacts the bottom of the template, and rotating the knob moves the locking teeth against the grooves. As the plate moves, the spring is stretched, completing the limitation of the vertical rod. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This specific embodiment is a formwork support for building construction, and its structural schematic diagram is shown below. Figure 1 , Figure 2 As shown, the system includes a base plate 1 and an adjustable support assembly 2. A bottom tube 4 is installed in the middle of the upper surface of the base plate 1. The upper end of the bottom tube 4 is threaded, and a middle tube 6 is movably installed on the upper end of the bottom tube 4. The adjustable support assembly 2 is movably installed on the top of the middle tube 6. A disc 5 is fixedly fitted on the top of the bottom tube 4 and the middle tube 6. Multiple sets of inclined plates 3 are installed on the upper surface of the base plate 1. Bolts 8 slide through the disc 5, and bolts 8 are threaded to the bolts 8. The crossbar 7 is connected to the disc 5 through the bolts 8. When actually supporting the formwork, the base plate 1 is placed on the ground, and then the middle tube 6 is installed. The number of middle tubes 6 installed depends on the height of the floor. Then, the adjustable support assembly 2 is installed. The adjustable support assembly 2 is used to contact the bottom of the formwork to support the formwork. Then, the crossbar 7 is installed through the disc 5 and the bolts 8. The other end of the crossbar 7 is connected to another set of formwork supports, so that the formwork supports form a whole.

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the adjustable support assembly 2 includes a top rod 206. The bottom of the top rod 206 is threaded and is threadedly connected to the bottom of the intermediate tube 6. A limiting plate 207 is sleeved on the lower part of the top rod 206. A thread is opened on the upper part of the top rod 206, and the thread is above the limiting plate 207. A rotating ring 204 is threaded to the top rod 206. Two sets of symmetrically distributed rotating rods 205 are installed on the outside of the rotating ring 204. A sliding ring 203 is slidably sleeved on the outside of the top rod 206, above the rotating ring 204. Two sets of symmetrically distributed rotating rods 205 are installed on the upper surface of the sliding ring 203. The push rod 202 has a support plate 201 mounted on its top. A vertical rod 208 is mounted on the middle of the lower surface of the support plate 201. The vertical rod 208 is slidably adapted to the top rod 206. The side of the vertical rod 208 has a toothed groove 209. An mounting plate 210 is mounted on the upper surface of the top rod 206. The mounting plate 210 is L-shaped and threaded with a screw 214. The screw 214 is connected to a knob 215. The end of the screw 214 away from the knob 215 is rotatably connected to a stop plate 213. Two sets of symmetrically distributed springs 211 are mounted on the side of the stop plate 213. The other end of the spring 211 is installed on the side of the mounting plate 210. The side of the abutment plate 213 away from the screw 214 has a locking tooth 212 that matches the toothed groove 209. The push rod 206 is connected to the upper part of the intermediate tube 6. Then, the rotating rod 205 is rotated to drive the rotating ring 204 to rotate. The rotating ring 204 moves upward along the push rod 206. The movement of the rotating ring 204 drives the sliding ring 203 to slide upward along the push rod 206. The upward movement of the sliding ring 203 drives the push rod 202 to move upward. The upward movement of the push rod 202 drives the support plate 201 to move upward. The support plate 201 moves upward. The upward movement causes the vertical rod 208 to move upward, and then the support plate 201 contacts the bottom of the template. Then, the knob 215 is turned to drive the screw 214 to rotate. The rotation of the screw 214 causes the abutment plate 213 and the retaining tooth 212 to abut against the tooth groove 209 (the slip ring 203 can rotate along the top rod 206. Before turning the knob 215, adjust the position of the tooth groove 209 of the vertical rod 208 to match the retaining tooth 212). When the abutment plate 213 moves, the spring 211 is stretched (the spring 211 limits the abutment plate 213 to prevent the abutment plate 213 from deflecting), thus completing the limitation of the vertical rod 208.

[0028] Working principle: When actually supporting the formwork, the base plate 1 is placed on the ground, and then the intermediate pipe 6 is installed. The number of intermediate pipes 6 installed depends on the height of the floor. Then, the adjustable support component 2 is installed. The adjustable support component 2 is used to contact the bottom of the formwork to support the formwork. Then, the crossbar 7 is installed through the disc 5 and bolt 8. The other end of the crossbar 7 is connected to another set of formwork support frames, so that the formwork support frames form a whole. The setting of the intermediate pipe 6 makes it easy to flexibly adjust the height of the formwork support frame according to the floor height, thus improving practicality.

[0029] The adjustable support assembly 2 works as follows: The top rod 206 is connected to the upper part of the intermediate tube 6. Then, rotating the rotating rod 205 causes the rotating ring 204 to rotate. The rotating ring 204 moves upward along the top rod 206, causing the sliding ring 203 to slide upward along the top rod 206. The upward movement of the sliding ring 203 causes the push rod 202 to move upward, which in turn causes the support plate 201 to move upward. The upward movement of the support plate 201 causes the vertical rod 208 to move upward. Then, the support plate 201 contacts the bottom of the template. Next, rotating the knob 215 causes the screw 214 to rotate. The rotation of the screw 214 causes the abutment plate 213 and the retaining tooth 212 to abut against the tooth groove 209. (The sliding ring 203 can rotate along the top rod 206. Before rotating the knob 215, adjust the vertical rod 208.) The toothed groove 209 of 08 is adapted to the locking tooth 212. When the abutment plate 213 moves, the tension spring 211 (the spring 211 limits the abutment plate 213 to prevent the abutment plate 213 from deflecting) completes the limiting of the vertical rod 208. The adjustable support component 2 increases the contact area with the lower surface of the template, preventing local stress concentration on the template, thereby avoiding large deformation of the template at the contact point and ensuring the quality of concrete molding. The threaded connection between the swivel ring 204 and the top rod 206 has self-locking properties (and the denser the thread, the greater the friction and the better the self-locking properties). In addition, the cooperation between the locking tooth 212 and the toothed groove 209 fixes and limits the vertical rod 208, thereby ensuring that the support plate 201 will not slide downward when under force, ensuring the quality of pouring and improving practicality.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
