Quickly-installed formwork support for building

Abstract

The utility model relates to the technical field of formwork supports, and discloses a rapid installation formwork support for construction, which comprises a support mechanism, and the upper part of the support mechanism is fixedly connected with an adjusting mechanism. Firstly, the second threaded sleeve is rotated, due to the fact that the second threaded sleeve and the threaded adjusting rod are connected in a threaded mode, the threaded structure enables the second threaded sleeve to move upwards along the threaded adjusting rod when the second threaded sleeve is rotated, and the second threaded sleeve can move upwards along with rising of the second threaded sleeve. When the device moves upwards, a second connector connected with the device moves upwards synchronously, then a second connecting plate is driven to move upwards, in the upward moving process of the second connecting plate, an upward acting force can be generated, and the force can generate an upward pushing effect on related parts at the bottom of the device; and the upward pushing force is gradually transmitted to the surface of the first connecting plate, so that the extrusion pressure between the first threaded sleeve and the threaded adjusting rod can be effectively reduced.

Description

Technical Field

[0001] This utility model application relates to the field of formwork support technology, specifically a quick-installation formwork support for construction. Background Technology

[0002] A quick-installation formwork scaffold is a temporary support structure used in building construction to support concrete structures. It is characterized by rapid installation, structural stability, and ease of disassembly and relocation. This type of formwork scaffold typically consists of steel pipes, steel plates, and connectors.

[0003] In the existing technology, formwork installation is required before concrete pouring in a building. During the installation process, the bottom formwork needs to be supported and fixed by a formwork support frame. Most existing bottom formwork support frames are quick-installation type. The quick-installation formwork support frame has a threaded height adjustment structure between the steel plate and the steel pipe to facilitate precise adjustment of the support rigidity.

[0004] In actual construction, after the quick-installation formwork supports the bottom formwork, the concrete pouring stage begins. As concrete is continuously poured onto the formwork surface, the upper pressure continues to rise. This pressure change directly affects the threaded adjustment structure of the quick-installation formwork, causing a significant increase in the squeezing pressure between the threads. This can easily lead to a situation where the threads become locked. As a result, when the quick-installation formwork needs to be disassembled later, the threaded adjustment structure becomes extremely difficult to turn, and in extreme cases, it may even be impossible to turn at all. This will undoubtedly severely slow down the disassembly progress of the installation workers and greatly reduce the disassembly efficiency. Utility Model Content

[0005] To address the issue that when the quick-installation formwork needs to be disassembled later, the threaded adjustment mechanism becomes extremely difficult to turn, and in extreme cases, it may even be impossible to turn at all. This would undoubtedly severely slow down the disassembly progress of the installation workers and significantly reduce the disassembly efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A quick-installation formwork support for construction includes a support mechanism. An adjustment mechanism is fixedly connected to the upper part of the support mechanism. The adjustment mechanism includes a threaded adjustment rod, a support steel pipe fixedly connected to the bottom of the threaded adjustment rod, and a first threaded sleeve threadedly connected to the surface of the threaded adjustment rod. A first connector is rotatably connected to the upper part of the first threaded sleeve, and a first connecting plate is fixedly connected to the upper part of the first connector. A second threaded sleeve is threadedly connected to the surface of the threaded adjustment rod, a second connector is rotatably connected to the bottom of the second threaded sleeve, and a second connecting plate is fixedly connected to the bottom of the second connector. A connecting outer tube is fixedly connected to the upper part of the second connecting plate, and a connecting inner tube is inserted into the connecting outer tube, and the connecting inner tube is fixedly connected to the first connecting plate.

[0008] Furthermore, the support mechanism includes a pad, the upper part of which is fixedly connected to the support steel pipe.

[0009] Furthermore, the No. 2 threaded sleeve is located below the No. 1 threaded sleeve.

[0010] Furthermore, a connecting frame is fixedly connected to the upper part of the first connecting plate, and the connecting frame is slidably inserted into the threaded adjusting rod.

[0011] Furthermore, a mounting bracket is fixedly connected to the side of the connecting frame, and a support rod is rotatably connected to the surface of the mounting bracket.

[0012] Furthermore, a second mounting bracket is rotatably connected to one end of the support rod, and a support steel plate is fixedly connected to the upper part of the second mounting bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, when it is necessary to disassemble the supporting steel plate, first rotate the No. 2 threaded sleeve. Since the No. 2 threaded sleeve and the threaded adjusting rod are connected by a thread, this thread structure allows it to move upward along the threaded adjusting rod when the No. 2 threaded sleeve is rotated. As the No. 2 threaded sleeve rises, the No. 2 connecting head connected to it will also move upward synchronously, thereby driving the No. 2 connecting plate to move upward. During the upward movement of the No. 2 connecting plate, it will generate an upward force, which can push the relevant components at the bottom of the device upward. This upward pushing force will be gradually transmitted to the surface of the No. 1 connecting plate. After receiving this pushing force, the No. 1 connecting plate will exert an upward pulling force on the No. 1 connecting head and the No. 1 threaded sleeve connected to it, which can effectively reduce the squeezing pressure between the No. 1 threaded sleeve and the threaded adjusting rod. Through the above-mentioned unique operation mode, this device avoids the problem of excessive locking between the No. 1 threaded sleeve and the threaded adjusting rod due to squeezing.

[0015] 2. In this utility model, after the support mechanism is installed, the No. 1 connector and the No. 1 connecting plate are lifted by turning the No. 1 threaded sleeve. At this time, the No. 1 connecting plate drives the connecting frame and the No. 1 mounting frame to move upward. The bottom template is supported by the support rod and the support steel plate. According to the support height requirements, the height of the support steel plate can be precisely adjusted by turning the No. 1 threaded sleeve. The upper gravity can be evenly transferred to the threaded adjustment rod by the support rod, avoiding uneven gravity transmission that could cause the threaded adjustment rod to bend.

Detailed Implementation

[0021] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Reference Figures 1-4 A quick-installation formwork support for construction includes a support mechanism 1. An adjustment mechanism 2 is fixedly connected to the upper part of the support mechanism 1. The adjustment mechanism 2 includes a threaded adjustment rod 21. A support steel pipe 11 is fixedly connected to the bottom of the threaded adjustment rod 21. A first threaded sleeve 22 is threadedly connected to the surface of the threaded adjustment rod 21. A first connector 23 is rotatably connected to the upper part of the first threaded sleeve 22. A first connecting plate 24 is fixedly connected to the upper part of the first connector 23. A second threaded sleeve 26 is threadedly connected to the surface of the threaded adjustment rod 21. A second connector 27 is rotatably connected to the bottom of the second threaded sleeve 26. A second connecting plate 28 is fixedly connected to the bottom of the second connector 27. A connecting outer tube 213 is fixedly connected to the upper part of the second connecting plate 28. A connecting inner tube 214 is inserted into the connecting outer tube 213. The connecting inner tube 214 is fixedly connected to the first connecting plate 24.

[0023] The No. 2 threaded sleeve 26 is located below the No. 1 threaded sleeve 22. The No. 1 connecting plate 24 is fixedly connected to the upper part of the connecting bracket 25, and the connecting bracket 25 is slidably inserted into the threaded adjusting rod 21.

[0024] Specifically, after the support mechanism 1 is installed, the first connector 23 and the first connecting plate 24 are lifted by turning the first threaded sleeve 22. At this time, the first connecting plate 24 drives the connecting frame 25 and the first mounting frame 29 to move upward. The bottom template is supported by the support rod 210 and the support steel plate 212. According to the support height requirements, the height of the support steel plate 212 can be precisely adjusted by turning the first threaded sleeve 22.

[0025] After the template is installed, concrete is poured. Under the gravity of the concrete, the pressure on the upper part of the template is transmitted to the surface of the supporting steel plate 212, and then transmitted downward through the supporting steel plate 212 and the supporting rod 210. The pressure is transmitted to the connection between the first threaded sleeve 22 and the threaded adjusting rod 21, causing the threads of the first threaded sleeve 22 and the threaded adjusting rod 21 to squeeze and lock each other.

[0026] By rotating the No. 2 threaded sleeve 26 and moving it upward along the threaded adjusting rod 21, the No. 2 connector 27 and the No. 2 connecting plate 28 are moved upward. The No. 2 connecting plate 28 then moves the outer connecting tube 213 upward, pushing the bottom of the inner connecting tube 214 upward. The inner connecting tube 214 then transmits the downward pushing force to the surface of the No. 1 connecting plate 24. The No. 1 connecting plate 24 then pulls the No. 1 connector 23 and the No. 1 threaded sleeve 22 upward, thereby reducing the squeezing pressure between the No. 1 threaded sleeve 22 and the threaded adjusting rod 21 and preventing them from being squeezed and locked. At this time, the worker screws the No. 1 threaded sleeve 22 to release the locking force caused by gravity. Then, the No. 2 threaded sleeve 26 and the No. 1 threaded sleeve 22 are screwed in respectively to detach the support steel plate 212 from the bottom of the template, facilitating the quick disassembly of the whole.

[0027] As an optimization solution, such as Figure 3 As shown, the support mechanism 1 includes a pad 12, the upper part of which is fixedly connected to the support steel pipe 11. A first mounting frame 29 is fixedly connected to the side of the connecting frame 25. A support rod 210 is rotatably connected to the surface of the first mounting frame 29. A second mounting frame 211 is rotatably connected to one end of the support rod 210. A support steel plate 212 is fixedly connected to the upper part of the second mounting frame 211.

[0028] Specifically, when the bottom formwork is supported by the support mechanism 1, the pressure transmitted from the upper part of the support steel pipe 11 is distributed and borne by the pad 12, thereby improving the stability of the bottom of the support steel pipe 11. Under the gravity of the concrete, the pressure of the upper part of the formwork is transmitted to the surface of the support steel plate 212, and then transmitted downward through the support steel plate 212 and the support rod 210. The support rod 210 can evenly transmit the upper gravity to the threaded adjusting rod 21, avoiding uneven gravity transmission that could cause the threaded adjusting rod 21 to bend.

[0029] Working principle: When the bottom template is supported by the support mechanism 1, the pressure transmitted from the upper part of the support steel pipe 11 is distributed and borne by the pad plate 12.

[0030] After the support mechanism 1 is installed, the No. 1 connector 23 and the No. 1 connecting plate 24 are lifted by turning the No. 1 threaded sleeve 22. At this time, the No. 1 connecting plate 24 drives the connecting frame 25 and the No. 1 mounting frame 29 to move upward. The bottom template is supported by the support rod 210 and the support steel plate 212. According to the support height requirements, the height of the support steel plate 212 can be precisely adjusted by turning the No. 1 threaded sleeve 22.

[0031] After the template is installed, concrete is poured. Under the gravity of the concrete, the pressure on the upper part of the template is transmitted to the surface of the supporting steel plate 212, and then transmitted downward through the supporting steel plate 212 and the supporting rod 210. The pressure is transmitted to the connection between the first threaded sleeve 22 and the threaded adjusting rod 21, causing the threads of the first threaded sleeve 22 and the threaded adjusting rod 21 to squeeze and lock each other.

[0032] By rotating the No. 2 threaded sleeve 26 and moving it upward along the threaded adjusting rod 21, the No. 2 connector 27 and the No. 2 connecting plate 28 are moved upward. The No. 2 connecting plate 28 then moves the outer connecting tube 213 upward, pushing the bottom of the inner connecting tube 214 upward. The inner connecting tube 214 then transmits the downward pushing force to the surface of the No. 1 connecting plate 24. The No. 1 connecting plate 24 pulls the No. 1 connector 23 and the No. 1 threaded sleeve 22 upward, thereby reducing the squeezing pressure between the No. 1 threaded sleeve 22 and the threaded adjusting rod 21 and preventing them from being squeezed and locked. At this time, the worker screws the No. 1 threaded sleeve 22 to release the locking force caused by gravity. Then, the No. 2 threaded sleeve 26 and the No. 1 threaded sleeve 22 are screwed in respectively to detach the support steel plate 212 from the bottom of the template.
