Description

Technical Field

[0001] This utility model belongs to the field of concrete pitched roof construction technology, specifically relating to a concrete pitched roof formwork fixing device. Background Technology

[0002] The fixing structure of the concrete pitched roof formwork is the key to ensuring a smooth surface, smooth lines, and meeting functional requirements after concrete pouring. During construction, the fixing of the formwork is very important, as it directly affects the quality and service life of the concrete structure.

[0003] The existing concrete pitched roof formwork fixing devices generally have a relatively fixed force when the hooks of the device press against the formwork support components after the formwork is connected to the support system. After long-term use, they are prone to loosening due to the influence of the external environment, which is quite inconvenient. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a concrete pitched roof formwork fixing device to solve the problem mentioned in the background art that the existing concrete pitched roof formwork fixing devices generally have a relatively fixed force when pressing the formwork support component with the hooks after connecting the formwork to the support system. After long-term use, they are prone to loosening due to the influence of the external environment, which is quite inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete sloping roof formwork fixing device, comprising a connecting screw, a nut threadedly connected to the outer side of one end of the connecting screw, two nuts being symmetrically arranged, a pressure plate slidably connected to the outer side of the connecting screw, two pressure plates being symmetrically arranged, a side plate fixedly connected to one side of each pressure plate, several side plates being symmetrically arranged, a first sliding rod slidably connected to the inner side of each side plate, several first sliding rods being symmetrically arranged, a first spring movably connected to the outer side of one end of each first sliding rod, a clamping plate fixedly connected to one end of each first sliding rod, a base plate fixedly connected to one side of the top of each pressure plate, several base plates being symmetrically arranged, a pressing screw threadedly connected to the inner side of each base plate, a sliding plate rotatably connected to the outer side of the bottom end of each pressing screw, and a pressing pad fixedly connected to one side of each sliding plate.

[0006] Preferably, a limiting ring is fixedly connected to the outer side of the other end of the first slide rod, and the limiting ring is located on one side of the side plate.

[0007] Preferably, a washer is movably connected to the outer side of one end of the connecting screw, and two washeres are symmetrically arranged, with each washer located between the nut and the pressure plate.

[0008] Preferably, all the pressing pads are made of flexible material, the bottom of all the pressing pads has a serrated structure, and a sliding plate is fixedly connected to the other side of each pressing pad.

[0009] Preferably, a second slide bar is fixedly connected to one side of each slide bar, and several second slide bars are symmetrically arranged. The second slide bars are all made of stainless steel, and a base plate is slidably connected to the outer side of each second slide bar.

[0010] Preferably, the outer surface of the connecting screw is provided with an electroplated anti-oxidation coating.

[0011] Preferably, each side of the substrate is fixedly connected to a bracket, and several brackets are symmetrically arranged, each bracket having a triangular structure.

[0012] Preferably, a second spring is movably connected to the outer side of the top end of the pressing screw, and the second spring is located above the substrate.

[0013] Compared with the prior art, this utility model provides a concrete sloping roof formwork fixing device, which has the following beneficial effects:

[0014] 1. This utility model features a pressing pad with a sliding plate fixedly connected to the top. A pressing screw is rotatably connected to the inner side of each sliding plate, and a base plate is threadedly connected to the outer side of each pressing screw. A pressure plate is fixedly connected to the bottom of each base plate. The connecting screw passes through a pre-drilled hole in the template and connects to the support rod. The pressure plate is slid to the position of the pressing and limiting component on the outer side of the connecting screw. Then, the nut is rotated clockwise, moving it to a position where it fully presses and fixes the pressure plate on one side of the nut. Then, each pressing screw is rotated on the inner side of the base plate, causing the pressing screw to lower the sliding plate to a position where it fully presses and limits the rods in the support system on one side of the pressing pad. This effectively increases the pressing force on the support rods during the limiting process, thus ensuring the stability of the device during long-term use.

[0015] 2. By setting gaskets, and connecting screws are movably connected to the inner side of the gaskets, and the gaskets are located between the nut and the pressure plate, the stability of the nut during long-term use can be effectively guaranteed.

[0016] 3. By setting a limiting ring, the first sliding rod is fixedly connected to the inner side of the limiting ring, and a side plate is slidably connected to the outer side of the first sliding rod, which can effectively reduce the risk of the first sliding rod falling off.

After the connecting screw 1 passes through the pre-drilled hole in the template, it is connected to the support rod. The pressure plate 3 is slid to the position of the pressing limit component on the outer side of the connecting screw 1. Then, the nut 2 is rotated clockwise to move the nut 2 to the position of fully pressing and fixing the pressure plate 3 on the outer side of the connecting screw 1. Then, each pressing screw 9 is rotated on the inner side of the substrate 8 to move the pressing screw 9 to the position of fully pressing and limiting the position of the rod in the support system on the side of the pressing pad 11.
