Description

Technical Field

[0001] The invention relates to the technical field of slipform construction, and in particular to a silo slipform construction method. Background Art

[0002] Silos are usually equipped with a discharge platform at the bottom of the silo, which is a big obstacle to the construction of slipforms. The construction method of the silo discharge platform is mostly to use the traditional method of building a floor-type scaffolding from the bottom of the silo to the discharge platform. After the discharge platform is completed, the rest of the silo wall is constructed with slipforms; or to use slipforms from the bottom of the silo to the bottom of the discharge platform, remove the slipforms, build a floor-type scaffolding to construct the discharge platform, and after the discharge platform is completed, build the rest of the silo wall with slipforms for the second time.

[0003] The construction of conventional silo discharge platforms takes a long time and is inefficient. Slipform construction cannot be completed in one go. The secondary slipform construction is time-consuming and labor-intensive, and the workload of construction workers is large. In addition, scaffolding needs to be erected around the circumference of the silo, which requires a large amount of scaffolding and is very dangerous. A large amount of turnover materials are used, and the construction cost is high. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a silo slipform construction method, which adjusts the template splicing method, sets the direction of the discharge platform as a single template, and when constructing to the discharge platform position, lifts the template at the discharge platform position together with the jack and lifting overhead slide of the slipform to the top of the discharge platform, vacating the discharge platform construction position, and the discharge platform construction does not require disassembly of the silo slipform. The discharge platform and silo slipform construction are carried out simultaneously, and the silo slipform construction is carried out continuously, thereby shortening the construction time and increasing the construction efficiency. Only the scaffolding at the discharge platform position needs to be set up, and the workload of the construction personnel is small, the amount of turnover materials used is small, and the construction cost is saved.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A silo slipform construction method is implemented by a silo slipform construction device, the slipform construction device comprises a slipform template, a jack, a lifting frame cylinder and a support rod, the jack is arranged on the top of the lifting frame, the lifting frame passes through the support rod, and slides up and down on the support rod, the slipform template is spliced ​​into an annular cylindrical template through a shaping template, and the silo slipform construction method specifically comprises the following contents:

[0007] S1. Use the slipform to construct the silo wall to the bottom of the discharge platform. When the concrete strength of the silo wall reaches the required level, lift the slipform template, jack and lifting frame of the silo slipform along the support rod to the top elevation of the discharge platform;

[0008] S2. A fixed connecting ring is provided on the support rod at the supporting position below the jack and the lifting frame, and the fixed connecting ring connects all the support rods in a ring shape on the circumferential cross section of the supporting position, and fixed pins are provided on both sides of the node position where the fixed connecting ring and all the support rods are connected;

[0009] S3. After fixing the silo slipform, set up a floor-standing scaffold inside the silo to the position of the discharge platform, and construct the discharge platform by setting up the template;

[0010] S4. After the construction of the discharge platform is completed and the concrete at the discharge platform position reaches the required strength, remove the discharge platform template, remove the fixed connection ring and fixed pin connecting the support rod, and readjust the support rod connecting the silo slipform jack and the lifting frame to meet the slipform construction standards;

[0011] S5. Continue to construct the cylinder wall structure above the discharge platform until the overall silo construction is completed.

[0012] Furthermore, in the construction method, the discharge platform and the surrounding silos are cast into a whole.

[0013] Furthermore, in the construction method, the fixed pin shaft of S2 is provided with a fastening device to prevent rotation.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1) Combining slipform construction with traditional scaffolding construction, there is no need to erect scaffolding on a large scale, which reduces the time for scaffolding, improves construction efficiency, saves construction time, reduces the workload of construction personnel, saves turnover materials such as scaffolding, saves construction costs, and improves the economic value of silo slipform construction.

[0016] 2) There is no need to repeatedly set up the slipform structure. The slipform construction can be completed in one go, saving the construction time of setting up the slipform twice. The slipform construction is constructed together with the discharge platform, saving labor and shortening the construction time. The entire silo wall is constructed using the slipform, with good construction quality, good integrity of the silo wall construction, and low construction fault tolerance.

[0020] The specific implementation mode of the present invention is further described below:

[0021] In the description of this patent, it is necessary to understand that the orientation or position relationship indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, vertical, horizontal" and "top, bottom" is usually based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention: the directional words "inside and outside" refer to the inside and outside relative to the contour of each component itself.

[0022] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly. If not otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

A fixed connecting ring 6 is set in the hole. The fixed connecting ring 6 connects all the support rods 5 in series at the supporting positions below the jacks 3 and the lifting frame 4. The circumferential cross-section of the fixed connecting ring 6 at the supporting position is connected in a ring shape. The fixed connecting rings of the ring-shaped connecting support rods 5 form a ring beam-like structure, which improves the supporting force of the support rods 5 and makes the jacks 3 and lifting frame 4 supporting the air sliding lifting more stable. Fixed pins 601 are set on both sides of the node where the fixed connecting ring 6 and the support rods 5 are connected. The fixed pins 601 play a stabilizing role for the sliding form as a whole;

[0026] S3. After fixing the silo slipform, set up a floor-standing scaffolding inside the silo to the position of the discharge platform 2, and construct the discharge platform 2 by setting up the template;

[0027] S4.
