Description

Technical Field

[0001] The utility model belongs to the technical field of concrete pouring, and in particular relates to a steel concrete column pouring structure. Background Art

[0002] Concrete is one of the most important civil engineering materials in contemporary times. It is a kind of artificial stone made of cementitious materials, granular aggregates, water, and admixtures and admixtures added when necessary in a certain proportion, and is evenly mixed, compacted, cured and hardened. Concrete has the characteristics of abundant raw materials, low price and simple production process, so its usage is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability and wide range of strength grades. The reinforced concrete column is filled with steel, which is the steel-concrete column. The reason why steel is added to the ordinary reinforced concrete column is to improve its bearing capacity and ductility. In the construction process, the shape of the steel-concrete column is generally formed by the template, and the steel is placed in the mold, and finally poured. After pouring, the template is easy to adhere to the concrete and difficult to remove.

[0003] Prior art, such as a document with authorization announcement number CN220747649U, discloses a steel-concrete construction pouring structure, including a mold shell, an inlet and outlet hole being provided on the back of the mold shell, a sealing baffle being provided on one side of the mold shell, a limiting mechanism being provided between the mold shell and the sealing baffle, the limiting mechanism including a limiting rod, a limiting nut, a positioning foot, an installation through hole and a limiting pressure plate, the positioning foot being fixedly installed on both sides of the mold shell, an installation through hole being provided on the positioning foot, a limiting rod being movably installed in the installation through hole, the limiting rod being provided with a limiting nut, a limiting pressure plate being fixedly installed at the end of the limiting rod, and a demoulding mechanism being provided on the mold shell.

[0004] The working principle of the above structure is: tighten the limit nut, and the limit pressure plate is limited to one side of the sealing baffle through the limit rod, so that the sealing baffle is fixed on the mold shell to form a mold of the steel concrete column; after pouring is completed, loosen the limit nut, and after starting the second hydraulic rod, it will push the demoulding top block forward, so that the sealing baffle will be detached; after starting the first hydraulic rod, its output end will push the steel concrete column forward, so that the mold shell will be detached from the steel concrete column, and then quickly complete the demoulding.

[0005] However, the device still has the following problems: first, each demoulding process requires all the limit nuts to be removed, which is time-consuming and laborious; second, demoulding the concrete column by pushing it up may cause the surface of the concrete column that has not been completely solidified to be worn and damaged.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection: it can be a mechanical connection or an electrical connection: it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Example 1

[0028] The utility model provides a steel-concrete column casting structure, which comprises two fixed side plates 11 and two connecting baffles 12 which are arranged opposite to each other. A connecting piece 1 is arranged at the connection between the fixed side plates 11 and the connecting baffles 12 .

[0029] It can be understood that the two side plates 11 have the same structure and are arranged opposite to each other, the two connecting baffles 12 have the same structure and are arranged opposite to each other, and the four plates are connected to each other to form a mold frame for casting steel concrete columns. Therefore, there are four "connections" between the fixed side plates 11 and the connecting baffles 12, so the number of connecting members 1 in this embodiment is four, and they have the same structure.

[0030] In this embodiment, the single connecting member 1 includes a first ear plate 101 arranged at the side end of the fixed side plate 11, a first connecting hole 102 arranged on the first ear plate 101, a second ear plate 103 arranged at the side end of the connecting baffle, a second connecting hole 104 arranged on the second ear plate 103, a connecting screw 105 for connecting the first connecting hole 102 and the second connecting hole 104, a limiting nut 106 arranged at the side end of the second ear plate 103 and connected to the connecting screw 105, and a fixing sleeve 107 arranged at the side end of the first ear plate 101 and used to insert the connecting screw 105; the fixing sleeve 107 is an internal threaded cylinder matching the connecting screw 105.

[0031] Among them, the two ends of the connecting screw 105 are respectively fixed by a fixing sleeve 107 and a limiting nut 106, so that the first ear plate 101 and the second ear plate 103 can be connected, and then the fixed side plate 11 and the connecting baffle 12 can be connected seamlessly to avoid leakage.

[0032] It is worth noting that the inner diameter of the first connection hole 102 ≥ the outer diameter of the fixing sleeve 107 > the inner diameter of the second connection hole 104. The effect of this arrangement is that the fixing sleeve 107 can pass through the first connection hole 102 but cannot pass through the second connection hole 104, so that the fixing sleeve 107 can directly push the second ear plate 103 to drive the connecting baffle 12 away from the fixed side plate 11 without releasing the limiting nut 106, thereby completing demoulding.

[0033] In this embodiment, a control member 2 for driving the fixed sleeve 107 to move closer to or further away from the first connection hole 102 is disposed on the fixed side plate 11. The control member 2 includes a mounting plate 201 disposed on the side plate 11, and a first driving cylinder 202 disposed on the mounting plate 201 and having an output end connected to the fixed sleeve 107.

[0034] As a further preferred embodiment of the present invention, a fixing member 3 is provided between two oppositely disposed fixed side panels 11. The fixing member 3 includes two vertical panels 301 respectively provided at the middle of the upper ends of the two fixed side panels 11, a connecting plate 302 whose two ends are respectively connected to the two vertical panels 301, and a lifting ear 303 provided at the upper end of the connecting plate 302.

[0035] The working principle of the casting structure provided in this embodiment is as follows: fix the positions of the two fixed side plates 11, and align the second ear plates 103 on the two connecting baffles 12 with the first ear plates 101 on the fixed side plates 11; pass the connecting screw 105 through the second connecting hole 104 and the first connecting hole 102 in sequence, and finally screw it into the fixed sleeve 107 to be fixed, and screw the limit nut 106 until it is tightly pressed against the surface of the second ear plate 103 to complete the connection between the fixed side plate 11 and the connecting baffle 12. After the casting is completed, directly start the first driving cylinder 202 to push the fixed sleeve 107 into the first connecting hole 102 and press against the second ear plate 103. The fixed sleeve 107 continues to move and pushes the second ear plate 103 away from the first ear plate 101, thereby releasing the connection between the connecting baffle 12 and the fixed side plate 11 and completing the demoulding. Finally, the entire casting structure can be lifted and removed by connecting the lifting device to the lifting ear 303.

[0036] Compared with the prior art, the casting structure provided in this embodiment has at least the following advantages: first, demoulding can be completed without removing the nuts one by one, which saves time and effort; second, the entire device can be hoisted and removed as a whole, retaining the original connection relationship, which helps to quickly build the mold frame during the next casting, thereby improving work efficiency and greatly saving time.

[0037] Example 2

[0038] The difference between this embodiment and embodiment 1 is that the structure of the control element 2 is different, and the specific structure is as follows:

[0039] The control member 2 includes a slide groove 203 arranged on the side plate 11 and extending along the width direction of the fixed side plate 11, two sliders 204 slidably connected to the slide groove 203 and respectively used to install the two fixed sleeves 107, an opening 205 arranged on the groove wall in the middle of the slide groove 203, a control slider 206 slidably connected to the opening 205, and a connecting rod 207 hingedly arranged at both ends of the control slider 206 and respectively hinged to the side ends of the two sliders 204; the overall height of the connecting rod 207 is higher than the height of the slide groove 203, and the connecting rod 207 includes two hingedly connected rod bodies to ensure smooth rotation.

[0040] As a further preferred embodiment of this embodiment, the control component 2 also includes a side bottom plate 208 arranged on the side plate 11 and located at the lower end of the opening 205, and a second driving cylinder 209 arranged on the side bottom plate 208 and with an output end connected to the connecting rod 207.

[0041] The working principle of this embodiment is: the second driving cylinder 209 drives the control slider 206 to approach / move away from the opening 205. During this process, the shape of the connecting rod 207 changes and transmits the force to the slider 204 on the slide groove 203, so that the two sliders 204 move away from / close to each other along the direction specified by the slide groove 203, thereby completing the connection or demolding between the connecting baffle 12 and the fixed side plate 11.

[0042] Compared with the solution of Example 1, the advantages of this embodiment are: first, the number of four driving cylinders can be reduced to two, saving economic costs; second, the connection on both sides of the same side plate 11 can be synchronously controlled to ensure the stability of demolding.

[0043] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
