Abstract
Description
Technical Field
[0001] This application relates to the technical field of construction auxiliary devices, and particularly to an anti-lateral adjustment and jacking device for positioning embedded steel column feet. Background Technique
[0002] In the foundation construction stage of steel structure projects, the on-site construction sequence of the existing embedded column foot nodes' caisson foundation is foundation brick formwork, cushion waterproofing, embedded anchor bolts, primary pouring of foundation concrete, installation of steel column feet, and secondary pouring of the foundation.
[0003] In the above construction project, since the foundation of the embedded column foot is poured in two times, the overall time cycle is long. In order to shorten the construction period and reduce the construction cost, the construction process of pouring the column foot anchor bolts and steel column feet in the foundation composite structure at one time is usually adopted in existing projects; compared with the previous two-time pouring forming process, although the one-time pouring forming construction process shortens the construction period, during the one-time pouring process, due to the lack of strong restraint on the horizontal displacement of the steel column foot by the anchor bolts wrapped by concrete, higher requirements are imposed on the horizontal positioning of the steel column foot.
[0004] During the concrete pouring process, in order to reduce the influence of concrete on the positioning of the steel column foot, it is necessary to take limiting measures for the steel column foot. In practical engineering applications, on-site construction personnel often directly use profiles such as angle steel for limiting, that is, one end of the angle steel is abutted against the steel column foot, and the other end is directly supported on the waterproof layer of the foundation side wall. However, since the length of the angle steel cannot be adjusted, there may be a situation where the steel column foot cannot be tightly jacked, resulting in the inability to effectively control the installation accuracy of the steel column foot, and further affecting the subsequent construction quality. Utility Model Content

Detailed implementation manners
[0033] The following further Figure 1 - attached Figure 5 describes the present application in detail.
[0034] The embodiment of the present application discloses an anti-lateral adjustment and jacking device for positioning an embedded steel column base.
[0035] Embodiment 1:
[0036] Referring to Figure 1 and Figure 2 , an anti-lateral adjustment and jacking device for positioning an embedded steel column base includes a horizontally placed support rod 1. A support base 2 is welded and fixed to the right end of the support rod 1. The support base 2 is arranged in a square flat plate shape, and the area of the support base 2 is larger than the area of the end face of the support rod 1. A buffer layer 6 is also provided on the support base 2. In this embodiment, the buffer layer 6 is preferably made of flexible plastic material and is adhesively fixed to the support base 2.
[0037] Referring to Figure 1 and Figure 2 , during use, the contact area between the support rod 1 and the foundation side wall is increased through the support base 2, thereby increasing the stress area between the support rod 1 and the foundation side wall, reducing the possibility of pressure damage on the foundation side wall, thus ensuring the quality of the waterproof layer finish on the foundation side wall and reducing the quality hidden danger of the waterproof layer on the foundation side wall.
[0038] Referring to Figure 2 and Figure 3 , a sliding sleeve rod 3 is sleeved on the left end of the support rod 1. The sliding sleeve rod 3 is coaxially arranged with the support rod 1, and the sliding sleeve rod 3 can slide along the axis direction of the support rod 1. A positioning member 4 is provided on the sliding sleeve rod 3 for positioning the sliding sleeve rod 3 after sliding. The positioning member 4 is a rotating block 41. The rotating block 41 is sleeved on the support rod 1 and is welded and fixed to the right end of the sliding sleeve rod 3. An external thread is integrally formed on the support rod 1, and the rotating block 41 is in threaded cooperation with the support rod 1. At the same time, a rotating handle 5 is also integrally formed on the rotating block 41.
[0039] Referring to Figure 1 and Figure 2, during use, the construction worker rotates the rotating block 41 by turning the rotating handle 5. Under the limiting action of the support rod 1, when the rotating block 41 rotates, the rotating block 41 will slide along the length direction of the support rod 1, thereby driving the sliding sleeve rod 3 to slide. When the left end of the sliding sleeve rod 3 abuts against the steel column base, the rotation of the rotating block 41 can be stopped. Then, through the threaded fit between the rotating block 41 and the support rod 1, the positioning of the sliding sleeve rod 3 is achieved, and the use process is simple and convenient.
[0040] Refer to Figure 1 and Figure 2 , it should be noted that the selection of the specification and model of the sliding sleeve rod 3 should have a certain stiffness and strength to ensure that during use, the sliding sleeve rod 3 can ensure that it will not deform under force after being adjusted and tightened against the steel column base. In this embodiment, it is recommended to select a φ48.3*3.6mm scaffolding pipe for the sliding sleeve rod 3, and the support rod 1, the rotating block 41, and the support base 2 should be selected in a matching manner. The threaded diameter on the support rod 1 should be 4mm less than the inner diameter of the sliding sleeve rod 3. In addition, the abutting surface of the support base 2 needs to be ensured to be flat and without sharp corners to ensure that the waterproof layer is not damaged; the overall device can be processed and modified using the adjustable support of the construction site scaffolding, which is convenient for obtaining materials, simple to manufacture, and low in cost, making the device have a certain convenience and operability.
[0041] The implementation principle of the embodiment of this application is as follows: during use, when the waterproof layer construction of the foundation cushion is completed, the anchor bolts are placed and positioned using the anchor bolt support, and then the steel column base is installed. After that, the anti-side adjustment and tightening device can be used for the adjustment and limiting work of the steel column base. The specific use steps are as follows. First, screw the rotating block 41 onto the support rod 1 to form the device with the sliding sleeve rod 3 sleeved on the support rod 1. Then, press the support base 2 against the side wall of the foundation cushion, and then turn the rotating block 41 by turning the rotating handle 5, so as to push the sliding sleeve rod 3 to extend out and slowly approach the steel column base. When the sliding sleeve rod 3 gradually abuts against the steel column base, the rotation of the rotating block 41 can be stopped. It should be noted that during the tightening process of the device, it should be carried out symmetrically and synchronously with respect to the steel column base to avoid displacement of the steel column base due to uneven force; at the same time, in order to ensure the effective adjustment of the horizontal positioning after the installation of the steel column base and the limited control of the horizontal displacement during the concrete pouring process, this device should be set around the steel column base, and the number of devices should be appropriately increased according to the buried depth and length to ensure the subsequent construction quality.
[0042] The difference between Embodiment 2 and Embodiment 1 is that:
[0043] Refer to Figure 4 and Figure 5A clamping assembly 7 is provided between the sliding sleeve 3 and the rotating block 41. The sliding sleeve 3 and the rotating block 41 are detachably connected through the clamping assembly 7. The clamping assembly 7 includes a connecting plate 71 and a locking member 72. The connecting plate 71 is welded and fixed to the right end of the sliding sleeve 3. Two groups of locking members 72 are provided. Both groups of locking members 72 are provided on the connecting plate 71, and the two groups of locking members 72 are respectively located on both sides of the sliding sleeve 3. The locking members 72 can be connected by bolts, magnets, etc. In this embodiment, the locking members 72 are preferably set as bolts.
[0044] Reference Figure 4 and Figure 5 When in use, the sliding sleeve 3 can be connected to the rotating block 41 by passing one end of the bolt through the connecting plate 71 and the rotating block 41 and then engaging with the nut. The overall connection process is simple and convenient, making it easy for construction workers to replace the sliding sleeve 3 of different lengths, thereby improving the applicability of the overall device.
[0045] Reference Figure 4 and Figure 5 A contact block 8 is also provided at the left end of the sliding sleeve 3. The contact block 8 is arranged in a rectangular plate. The area of the end face of the contact block 8 is larger than the area of the end face of the sliding sleeve 3. An insertion rod 9 is integrally formed on the contact block 8. A slot 31 is integrally formed at the left end of the sliding sleeve 3. The insertion rod 9 can be threadedly connected to the slot 31. When in use, the contact block 8 is screwed to make the insertion rod 9 threadedly connected to the left end of the sliding sleeve 3, thereby realizing a detachable connection between the contact block 8 and the sliding sleeve 3, so that construction personnel can replace contact blocks 8 of different sizes, thereby ensuring the support stability of the steel column foot.
[0046] The implementation principle of the embodiment of the present application is as follows: before use, the rotating block 41 is first screwed on the support rod 1, and then the sliding sleeve 3 is put on the support rod 1, and the sliding sleeve 3 is moved. Then, the sliding sleeve 3 is fixed to the rotating block 41 by bolts, and finally the abutment block 8 is installed on the sliding sleeve 3 to form an anti-side adjustment and tightening device; when in use, the support base 2 is close to the side wall of the foundation cushion layer, and the rotating block 41 is rotated by toggling the rotating handle 5, thereby pushing the sliding sleeve 3 to extend outward to slowly approach the steel column foot until the abutment block 8 gradually tightens the steel column foot. The toggling of the rotating block 41 can be stopped, thereby achieving the support positioning of the steel column foot; at the same time, in order to ensure the effective adjustment of the horizontal positioning of the steel column foot after installation and the limited control of the horizontal displacement during concrete pouring, the device needs to be set around the steel column foot, and the number of the device settings can be increased as appropriate according to the burial depth and length, so as to ensure the subsequent construction quality.
[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
