[0020] like Figures 1 to 3 As shown, the utility model is a support fixture for installing a steel structure in a concrete frame, comprising two clamping steel plates 1, the clamping steel plates 1 are of a channel steel structure, and when in use, a flat surface is used as an end surface in contact with a concrete structure column 2, so as to increase the contact area with the concrete structure column 2 and ensure the stability of the clamping steel plates 1 after installation; both ends of the two clamping steel plates 1 are correspondingly provided with connecting holes 3, and the two connecting holes 3 at each end are penetrated with screws 4, and the screws 4 are located at the ends of the two clamping steel plates 1 away from each other and are provided with fixing nuts, and the fixing nuts It is preferred to set two to increase the tightening force and prevent loosening. In addition, a washer is also provided between the inner nut and the clamping steel plate 1 to disperse the pressure and improve the connection stability between the screw 4 and the clamping steel plate 1. In addition, two auxiliary clamps 5 with adjustable spacing are provided on the opposite side of the two clamping steel plates 1. The auxiliary clamps 5 are arranged vertically with the clamping steel plates 1 to form a positive angle installation structure, which is installed at the positive angle position of the concrete structure column 2 to increase the contact area between the entire clamp and the concrete structure column 2 and ensure the stability of the clamp installation. When in use, the two clamping steel plates 1 are clamped on the concrete structure column 2 using the screw 4 and the nut, and then the fall chain is installed on the side of the clamping steel plate 1 that needs to be hoisted. It should be noted that since the concrete structure column 2 is vertically arranged, the clamp usually needs to be arranged on two symmetrical concrete structure columns. When lifting the steel beam, the two fall chains are connected to the two ends of the steel beam, and the lifting of the steel beam is completed at the same time.

[0021] Furthermore, each auxiliary clamping plate 5 is symmetrically provided with two limiting sliding sleeves 6 on one side close to the clamping steel plate 1, and each limiting sliding sleeve 6 is slidably arranged on the side walls at the upper and lower ends of the clamping steel plate 1; in addition, two positioning plates 7 are symmetrically arranged on the clamping steel plate 1, and the two positioning plates 7 are located at the end away from the two auxiliary clamping plates 5, and each positioning plate 7 is threadedly provided with a positioning bolt 8. During installation, the auxiliary clamping plate 5 can be tightened by rotating the positioning bolt 8 to achieve close contact between the auxiliary clamping plate 5 and the concrete structure column 2, further ensuring the stability of the entire fixture after installation; wherein, the height of the auxiliary clamping plate 5 is greater than the height of the clamping steel plate 1 to increase the contact area between the auxiliary clamping plate 5 and the concrete structure column 2, and improve the stability of the fixture after installation; preferably, each positioning plate 7 is provided with two upper and lower positioning bolts 8, and the screw rod 4 is located between the two positioning bolts 8, which can avoid interference with the installation and disassembly of the screw rod 4, and can enhance the tightness of the contact between the auxiliary clamping plate 5 and the concrete structure column 2 by positioning the auxiliary clamping plate 5 by the upper and lower positioning bolts 8.

[0022] In the present embodiment, a rubber block 9 is provided at one end of each auxiliary clamping plate 5 close to the positioning bolt 8. The provision of the rubber block 9 can prevent the positioning bolt 8 from directly contacting the auxiliary clamping plate 5 and causing wear between the two during the process of continuous tightening after the positioning bolt 8 comes into contact with the auxiliary clamping plate 5, thereby ensuring that the structural strength of the auxiliary clamping plate 5 is not affected and extending the service life of the auxiliary clamping plate 5.

[0023] Furthermore, in the present embodiment, the limiting sleeve 6 comprises a horizontal section 6-1 vertically connected to the auxiliary clamping plate 5, a reinforcing rib plate is arranged between the horizontal section 6-1 and the auxiliary clamping plate 5 to enhance the structural strength of the limiting sleeve 6 after being connected to the auxiliary clamping plate, a right-angle section 6-2 is vertically arranged at one end of the horizontal section 6-1 away from the auxiliary clamping plate 5, and a space for accommodating the side wall of the clamping steel plate 1 is formed between the right-angle section 6-2 and the horizontal section 6-1; such an arrangement can realize the sliding connection between the limiting sleeve 6 and the clamping steel plate 1, provide guidance for the sliding of the auxiliary clamping plate 5, and enhance the stability of the subsequent auxiliary clamping plate 5 when subjected to force; specifically, A bearing block 10 is fixedly arranged between the upper and lower limiting sleeves 6, and a mounting hole 11 is provided on the bearing block 10. The bearing block 10 can be used for the installation and fixation of the fall chain, and provides a support carrier for the installation of the fall chain; because the upper and lower limiting sleeves 6 of each auxiliary clamping plate 5 are slidably sleeved with the side wall of the clamping steel plate 1, the contact area with the clamping steel plate 1 is increased, and the side wall of the clamping steel plate 1 is formed to accommodate and cover. At the same time, by means of the close contact between the auxiliary clamping plate 5 and the concrete structure column 2, the bearing capacity of the bearing block 10 can be effectively improved, and the stability of the fall chain during the lifting process after it is installed on the bearing block 10 is ensured. In addition, the setting of the mounting hole 11 on the bearing block 10 can also realize the central installation of the fall chain by inserting a supporting steel rod into the mounting hole 11 when the size of the concrete structure column 2 is large, which provides convenience for the lifting of the steel beam.

[0024] Furthermore, a threaded rod 12 is provided at one end of the clamping steel plate 1 close to the supporting block 10, and the threaded rod 12 is arranged parallel to the clamping steel plate 1, and a through hole for the threaded rod 12 to pass through is opened on the supporting block 10; a locking nut 13 is provided on the threaded rod 12 at one end of the two supporting blocks 10 away from each other, which is used to position the supporting blocks 10 after being adjusted into place; by cooperating with the positioning bolts 8, the positioning operation of the auxiliary clamping plate 5 on the front and rear sides of the clamping steel plate 1 can be realized, thereby further enhancing the stability of the auxiliary clamping plate 5.
