Technical Field

[0001] The utility model relates to the technical field of drainage ditch construction, in particular to a railway tunnel drainage ditch support frame. Background Art

[0002] With the rapid development of my country's economy, the urbanization process has gradually accelerated, the scale of cities has continued to expand, and a large number of migrant populations have poured into cities. At the same time, the number of motor vehicles has increased rapidly, and transportation demand has increased sharply, resulting in urban road congestion, vehicle jams, and chaotic traffic order. This not only affects people's travel, but also becomes a bottleneck hindering urban development. To solve urban traffic problems, major and medium-sized cities are actively promoting the construction of urban rail transit. The construction of drainage ditches is an issue that must be considered during subway construction.

[0003] The construction of drainage ditches in railway tunnels generally adopts prefabrication or cast-in-place concrete. If prefabrication is adopted, the secondary transportation and installation of prefabricated components are very troublesome, there are too many joints, the processing quality is difficult to guarantee, and the overall cost is high. Therefore, most of them are cast-in-place concrete. During the pouring process, formwork is used to shape the drainage ditch. The existing support method for the formwork usually uses multiple steel pipes to support the formwork. The support process is relatively cumbersome and cannot quickly and effectively support the formwork to the required shape at a specified distance. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-5 The two ends of the positive and negative threaded column 7 are respectively threadedly connected to the inner ends of the two horizontal plates 201.

[0025] It can be understood that by placing the template in the slot formed between the block 6 and the side panel 1, the block 6 and the side panel 1 support the template, thereby achieving the purpose of quickly supporting the template, and rotating the positive and negative threaded columns 7 through the anti-slip sleeve, thereby driving the two cross plates 201 and the two side panels 1 to slide on the surface of the slide rod 202, thereby adjusting the width between the two side panels 1, so as to adapt to the pouring of drainage ditches of different widths, and by setting scale lines, it is convenient to observe the distance between the two sides.

[0026] Specifically, the lower ends of the two side panels 1 are respectively provided with vertically sliding support legs 3, and the support legs 3 are T-shaped. The inner side of the side panel 1 is provided with a locking mechanism 9 for fixing the height of the support legs 3. The locking mechanism 9 is a bolt threadedly connected to the side of the side panel 1.

[0027] It can be understood that the height of the side panel 1 and the block 6 can be adjusted by sliding the support leg 3 up and down at the bottom of the side panel 1, so as to facilitate the support of templates of different heights, and the support leg 3 can be fixed to the surface of the side panel 1 by setting bolts.

[0028] Specifically, two groups of connecting components 5 for reinforcing adjacent support frames are provided on the upper surface of the bidirectional telescopic component 2. The connecting component 5 includes two pins 503 fixed on the upper surface of the horizontal plate 201 and a connecting rod 501 connected to the pins 503. Both ends of the connecting rod 501 are fixedly connected to the sleeve 502, and both ends of the connecting rod 501 are inserted into the surface of the pin 503 through the sleeve 502.

[0029] It is understandable that the connecting rod 501 is inserted into the surface of the pin shaft 503 through the sleeve 502, thereby facilitating the connection of adjacent support frames and improving the fixing effect of the template.

[0030] Specifically, a one-way limit assembly 4 for limiting the horizontal plate 201 is provided on the back of one of the horizontal plates 201. The one-way limit assembly 4 includes a limit piece 401 provided on the back of the horizontal plate 201 and a plurality of oblique tooth grooves 404 provided on the back of the slide bar 202. The limit piece 401 is L-shaped, and an inclined surface is provided at one end of the limit piece 401 close to the slide bar 202. A connecting shaft 402 is fixedly connected to the back of the horizontal plate 201. The limit piece 401 is rotatably connected to the surface of the connecting shaft 402. A torsion spring 403 is sleeved on the surface of the connecting shaft 402 for rotating one end of the inclined surface of the limit piece 401 inwardly. The oblique tooth grooves 404 cooperate with the limit piece 401.

[0031] It is understandable that, since pressure is generated on the outside of the formwork and the side panel 1 when pouring cement, the torsion spring 403 drives one end of the inclined surface of the limiting member 401 to be clamped on the surface of the oblique tooth groove 404, thereby preventing the side panel 1 and the cross panel 201 from being subjected to excessive pressure and moving inward, causing displacement of the formwork. At the same time, under the action of the oblique tooth groove 404, the positive and negative threaded columns 7 drive the cross panel 201 to slide outward on the surface of the slide rod 202 without generating resistance, thereby achieving the purpose of one-way limiting.

[0032] In the present invention, according to the construction standards, the width between the two side panels 1 is adjusted, and the positive and negative threaded columns 7 are rotated by the anti-slip sleeve to drive the two cross plates 201 and the two side panels 1 to slide outward on the surface of the slide rod 202. With the help of the scale line, the width between the two side panels 1 is adjusted to the required range, and the template is placed in the slot formed between the side panels 1 and the block 6. The support legs 3 are limited by the bolt contact so that the support legs 3 and the template are in contact with the ground at the same time, and the support legs 3 are locked by the bolts. Multiple templates are placed according to the above After the support is placed and fixed, the connecting rod 501 is inserted into the surface of the pin shaft 503 through the sleeve 502 to further connect the multiple support frames and the template, thereby improving the stability effect. Cement is poured on the outside of the template to form a drainage ditch. When the support frame needs to be recovered, the support leg 3 is retracted into the side panel 1, and at the same time, one end of the limiter 401 is pressed to disengage the limiter 401 from the oblique tooth groove 404, thereby releasing the limit on the horizontal plate 201, and the bidirectional telescopic assembly 2 is shortened to the shortest point through the positive and negative threaded columns 7 to reduce the occupied space.
