Description

Technical Field

[0001] The invention relates to the technical field of pouring assembled steel column external concrete, in particular to an assembled steel column external concrete production device. Background Art

[0002] With the acceleration of the process of building industrialization, prefabricated buildings and rigid-structured houses have been vigorously developed. Steel columns with concrete-wrapped steel components have become energy-saving building materials. Because of their high bearing capacity, high rigidity, good seismic performance and convenient construction, they have been widely used in high-rise buildings, large-span structures, bridge engineering and other fields.

[0003] At present, the pouring of steel columns is generally done by pouring concrete after installation. However, this not only delays the construction period by waiting for the concrete to solidify, but also has certain operational difficulties in high-rise construction after on-site installation. For this reason, we have designed a production equipment that can pre-produce most types of steel columns in the factory after welding the connecting plates (for connection with the main part of the engineering building or adjacent steel columns) and then transport them directly to the construction site.

[0085] Wherein, the sealing unit 4 of the former type comprises:

[0086] Sealing rubber pads 41 are correspondingly arranged at the gaps between each of the steel molds 2 and the steel columns, and match the shape of the gaps formed;

[0087] The mounting mechanism 42 is disposed at each sealing rubber pad 41 and is used to squeeze the sealing rubber pad 41 into the gap to form a seal.

[0088] Wherein, the mounting mechanism 42 comprises:

[0089] A mounting plate 421 is correspondingly arranged on the casting frame 1 at a corresponding position of each sealing rubber pad 41, and a slot 422 for inserting the sealing rubber pad 41 is arranged on the mounting plate 421;

[0090] A rolling assembly is provided on the mounting plate 421, and is used to press the sealing rubber pad 41 into the gap, and to hold both sides of the sealing rubber pad 41 at the rolling position during the rolling process, so as to prevent the sealing rubber pad 41 from not being aligned with the gap during the rolling process, thereby causing rolling failure;

[0091] Wherein, the rolling assembly comprises:

[0092] A preliminary rolling portion 423 is provided on the mounting plate 421 and is used for initially inserting the sealing rubber pad 41 into the corresponding gap;

[0093] The pressing portion 424 is disposed on the mounting plate 421 , and is used to squeeze the sealing rubber pad 41 into the gap after the preliminary rolling portion 423 preliminarily presses the sealing rubber pad 41 into the gap, so that the end surface of the sealing rubber pad 41 and the inner membrane of the steel mold 2 remain flush.

[0094] In addition, the preliminary rolling unit 423 includes:

[0095] A pressure roller 4231 is arranged at a position of the slot 422 on a side of the mounting plate 421 away from the steel mold 2;

[0096] A slide rail 4232 is arranged on the mounting plate 421 along the track of the slot 422;

[0097] A clamping and limiting member is provided on the other side of the mounting plate 421 from the pressing roller 4231, and is used for clamping and limiting the sealing rubber pad 41 at the position when the pressing roller 4231 presses the sealing rubber pad 41;

[0098] A connecting power member is disposed between the pressing roller 4231 and the slide rail 4232, and is used to connect the pressing roller 4231 and the slide rail 4232, and to make the pressing roller 4231 and the clamping limiter slide along the slide rail 4232;

[0099] Wherein, the clamping limiter comprises:

[0100] There are two sets of outer clamping rollers 4233, which are symmetrically arranged on both sides of the outer side of the sealing rubber pad 41;

[0101] An inner limit plate 4234 is arranged on the mounting plate 421 to fit the inner side surface of the sealing rubber pad 41;

[0102] The electric telescopic arm 4235 is arranged on the outer clamping roller 4233, and is used to drive the outer clamping roller 4233 to rotate so that the outer clamping roller 4233 and the outer side of the sealing rubber pad 41 are in contact with each other. The rotation of the electric telescopic arm 4235 drives the electric telescopic rod to rotate through the rotating motor arranged on the connecting power part, so that the outer clamping roller 4233 can be in contact with the outer side end of the sealing rubber pad 41.

[0103] The inner limit plate 4234, the sealing pad 41 and the mounting plate 421 are connected by Fig.12 The telescopic plate 4237 shown is telescopically connected.

[0104] At the same time, the connecting power member is set as an I-shaped electromagnetic slider 4236 on the slide rail 4232, one side of the electromagnetic slider 4236 is connected to the pressure roller 4231, and the other side is connected to the electric telescopic arm 4235;

[0105] During the initial rolling process, the electromagnetic slider 4236 will drive the pressure rollers 4231 and the outer clamping rollers 4233 on both sides thereof to move, and the outer clamping rollers 4233 will adjust their positions and angles through the electric telescopic arms 4235 according to the positions of the pressure rollers 4231, so that the outer clamping rollers 4233 and the pressure rollers 4231 are on the same vertical line, thereby achieving the limiting of the inner sealing rubber pad 41 during rolling process;

[0106] In addition, in order to better fit the sealing pad 41 into the gap, the inner end of the sealing pad 41 is configured to be in a boss shape.

[0107] Wherein, the pressing portion 424 includes:

[0108] A pressing plate 4241 is disposed outside the mounting plate 421;

[0109] The third power member 4242 is located on both sides of the steel mold 2 and is fixedly arranged on the connecting strip 52. The third power member 4242 located at the lower end of the steel mold 2 is arranged on the casting frame 1. The third power member 4242 is arranged as a hydraulic arm.

[0110] Finally, the pouring frame 1 is also provided with an automatic concrete distributor for pouring concrete into the steel mold 2, and a vibrating rod for vibrating after the concrete distributor pours;

[0111] Working principle:

[0112] Step 1: Use the lifting equipment to lift the steel column body 8 to the installation groove 72 of the calibration block 71 on the front and rear ends of the casting frame 1;

[0113] Step 2: The two groups of steel columns on the lower side of the four groups of steel molds 2 move toward the middle under the action of the lateral moving components on both sides, so as to fit the lower half of the steel column body 8. During the movement of the lateral moving components on both sides, the positions of the two ends of the steel column are calibrated by the calibration component 7, and clamping is achieved;

[0114] Step 3: One of the sealing units 4 in the first group seals the gap formed by the two adjacent steel molds 2 at the lower end of the steel column body 8 and the connecting plate 3 passing through the through groove 21, and at the same time, the sealing units 4 in the second group seal the gap formed between the front and rear ends of the steel column body 8 and the steel molds 2. The shape of the connecting plate 3 at this location on the steel column body 8 of the second sealing unit 4 is relatively simple, and two semi-rectangular frame-type sealing pads 41 can be directly set, and the sealing is installed manually;

[0115] Step 4: The first pouring is performed by an automatic placing machine. The height of the first pouring is the lowest horizontal height of the through groove 21 of the adapter connecting plate 3 at the lower end, and is marked as point a in the attached figure *. The first vibration is performed by a vibrating plate. This is currently done to prevent one-time pouring. Since the pouring position is high and the pouring is in a rectangular ring shape, it is difficult to discharge the bubbles in the concrete below. If the vibration force is too large, the concrete is easy to flow out from the gap at the sealing pad 41, although it has been sealed.

[0116] Step 5: The two groups of steel column bodies 8 at the upper end are clamped on the connecting plates 3 from which the two groups of steel columns at the lower end of the upper steel mold moving assembly 6 have extended, and then the gaps at the connection are sealed by the two sealing units 4 on both sides of the previous group, and the gaps at the front and rear ends are sealed by the two semi-rectangular ring-shaped sealing pads 41. Then a pouring port is left above the two groups of steel column bodies 8 at the upper end, and then a second pouring is carried out from the pouring port through an automatic material placing machine, and a second vibration is carried out. Multiple pouring ports can be set, and the opening can be set larger to facilitate pouring and to facilitate the discharge of bubbles. The pouring port can also be as follows Figure 1 As shown, it is set to be fully open to facilitate pouring;

[0117] It should be noted that, before calibration, a release agent needs to be applied to the inner wall of the steel mold 2 so as to facilitate separation of the steel mold 2 and the poured concrete after solidification during later demoulding.

[0118] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
