Description

Technical Field

[0001] The utility model belongs to the technical field of building formwork, and particularly relates to a fixing component for pier column formwork. Background Art

[0002] Pier columns mainly play a bearing role, and transmit the loads transmitted from the upper structure reliably and effectively to the foundation. They are the main components in bridge engineering. When constructing existing pier columns, generally, the pier column formwork needs to be erected first, and then concrete is poured. After demoulding, the pier column is obtained.

[0003] In the prior art, for the convenience of transportation, building formworks are mostly prefabricated in factories in advance and then transported to the construction site for splicing. However, for the existing pier column formworks, when they are assembled in combination, it is not convenient to position and assemble them, which affects the work progress. Moreover, the steel structure formworks are fixed singly by bolts, and the connection strength of the steel structure formworks is relatively low, thus affecting the pouring and forming effects. In addition, due to the high height of the pier column formwork, the external wind force easily causes the pier column to tilt, affecting the pouring accuracy of the pier column.

[0004] Therefore, a fixing component for pier column formwork is proposed. Content of the Utility Model

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] To make the above objects, features and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0024] Referring to Figures 1 to 4 as shown, this embodiment provides a fixing component for a pier column formwork. The pier column formwork is composed of several template components connected up and down, including: the first mounting plate 1 and the second mounting plate 2 symmetrically fixed on the front and rear sides of the template component. The first mounting plate 1 and the second mounting plate 2 are tightened by a tensioning component. Columns 3 are fixedly connected to both sides of the first mounting plate 1 and the second mounting plate 2. The bottom end of the column 3 is fixed underground, and guy wires 4 are fixedly connected to the upper part of the column 3. The four guy wires 4 are inclined circumferentially along the pier column formwork, and the end far from the column 3 is fixedly connected with a ground nail 5, and the ground nail 5 is inserted underground.

[0025] The template components are connected up and down to form a pier column formwork. Each template component is fixedly connected to its corresponding first mounting plate 1 and second mounting plate 2. The first mounting plate 1 and the second mounting plate 2 are fastened by a tensioning assembly, so that the first mounting plate 1, the second mounting plate 2 and the template component in the middle thereof form a firm whole. Multiple upper and lower corresponding first mounting plates 1 and second mounting plates 2 are connected in series by columns 3, and then multiple template components connected up and down are connected in series into a whole, increasing the integrity and firmness of the pier column formwork. Finally, through guy ropes 4, the pier column formwork and the first mounting plate 1, the second mounting plate 2 and the column 3 on the outside thereof are integrally pulled, and the whole is pulled from multiple angles to prevent the pier column formwork from tilting after being affected by wind or other external forces. And the guy ropes 4 are driven into the ground by ground nails 5, and the whole is fixedly connected to the ground, further increasing the firmness of the pier column formwork.

[0026] In a further optimized solution, the template component is formed by splicing the first arc plate 6, the second arc plate 7, the first straight plate 8, the third arc plate 9, the fourth arc plate 10 and the second straight plate 11 end to end; the first arc plate 6 and the second arc plate 7, and the third arc plate 9 and the fourth arc plate 10 are fixedly connected by arc plate connecting bolts 12.

[0027] The section of the template component is in a runway shape, and the runway shape is a common cross-sectional shape of the pier column. The connection of the first arc plate 6, the second arc plate 7, the first straight plate 8, the third arc plate 9, the fourth arc plate 10 and the second straight plate 11 end to end is beneficial to prefabrication in the early stage. The first arc plate 6 and the second arc plate 7, and the third arc plate 9 and the fourth arc plate 10 are simply connected by arc plate connecting bolts 12, and further fastening can be achieved by the tensioning assembly squeezing the first mounting plate 1 and the second mounting plate 2 to make them closely connected.

[0028] In a further optimized solution, the first straight plate 8 is fixedly connected to the first mounting plate 1 by a plurality of screws 13 on the outside, and the second straight plate 11 is fixedly connected to the second mounting plate 2 by a plurality of screws 13 on the outside.

[0029] The screws 13 move the first straight plate 8 closer to and fasten it to the first mounting plate 1, and move the second straight plate 11 closer to and fasten it to the second mounting plate 2.

[0030] In a further optimized solution, a first tensioning steel bar 14 is arranged through the first straight plate 8 and the second straight plate 11. Both ends of the first tensioning steel bar 14 respectively penetrate through the first straight plate 8, the first mounting plate 1 and the second straight plate 11, the second mounting plate 2 and are threadedly connected with nuts.

[0031] The first tensioning steel bar 14 reduces the gap between the first straight plate 8, the first mounting plate 1, the second straight plate 11 and the second mounting plate 2, and makes the first straight plate 8 and the second straight plate 11 press against each other, thereby making the entire template component approach each other, increasing the strength and firmness of the template component.

[0032] According to a further optimized solution, the first curved plate 6 and the first mounting plate 1 , the second curved plate 7 and the second mounting plate 2 , the third curved plate 9 and the first mounting plate 1 , and the fourth curved plate 10 and the second mounting plate 2 are fixedly connected by second tensioning steel bars 15 .

[0033] The second tensioning steel bars 15 bind the first curved plate 6, the second curved plate 7, the third curved plate 9 and the fourth curved plate 10 to fix them on the mounting plate. All formwork parts are fixed to the mounting plate, further increasing the strength and firmness of the formwork assembly and enhancing its integrity.

[0034] A further optimized solution is that the second tension steel bars 15 between the first curved plate 6 and the first mounting plate 1 are arranged along the tangent of the first curved plate 6; a first connecting rib 16 is fixedly connected to the first curved plate 6, and a second connecting rib 17 is fixedly connected to the first mounting plate 1; the second tension steel bars 15 pass through the first connecting rib 16, the first mounting plate 1 and the second connecting rib 17 in sequence, and are threadedly connected with nuts at both ends.

[0035] The second tension steel bar 15 between the first curved plate 6 and the first mounting plate 1 is arranged along the tangent of the first curved plate 6, pulling the first curved plate 6 closer to the first straight plate 8 and the first mounting plate 1, making it more integral. The remaining second tension steel bars 15 have the same principle and structure as this steel bar, and will not be repeated.

[0036] According to a further optimized solution, the tensioning assembly includes two symmetrically arranged screw rods 19, the outer ends of the two screw rods 19 are fixedly connected with a stopper 18, and the inner ends of the two screw rods 19 pass through the first mounting plate 1 and the second mounting plate 2 and are threadedly connected with a threaded barrel 20.

[0037] By rotating the threaded barrel 20, the two screws 19 can be moved closer to or farther from each other, and the stopper 18 can abut against the first mounting plate 1 or the second mounting plate 2. When the threaded barrel 20 rotates, the first mounting plate 1 or the second mounting plate 2 can be driven closer to each other to form a tension structure, so that the structure between the first mounting plate 1 or the second mounting plate 2 is more tightened, and the first mounting plate 1 or the second mounting plate 2 is formed into a whole. The tension structure formed by rotating the threaded barrel 20 is simpler than the installation and implementation of tensioning steel bars, simplifies the installation process, and saves manpower.

[0038] According to a further optimized solution, a rotating handle 21 is fixedly connected to the outer circumference of the threaded barrel 20 .

[0039] The handle 21 is turned to facilitate the rotation of the threaded barrel 20 .
