Description
Technical Field
[0001] The utility model belongs to the technical field of construction engineering, and particularly relates to a secondary grouting support device for an embedded steel column base. Background Technique
[0002] In a steel frame structure, there is often a reserved space between the bottom of a steel column and the concrete of the bottom plate, and secondary grouting is required to ensure that the force of the steel column is transmitted to the foundation through the concrete cast in place at the bottom of the column.
[0003] However, during the grouting process, carpenters are required to support the bottom formwork. During the formwork support process, due to difficult fixation, problems such as grout leakage and formwork bulging occur during the grouting process, and subsequent treatment will cause waste of human resources.
[0004] Currently, the traditional method is to support the formwork at the bottom and fix the formwork through positioning bars. The construction difficulty is relatively large, and problems such as grout leakage and formwork bulging are likely to occur during the grouting process, resulting in poor appearance and affecting the project quality. Content of the Utility Model
[0005] The utility model provides a secondary grouting support device for an embedded steel column base, which can solve the problems pointed out in the background technique.
[0006] The secondary grouting support device for an embedded steel column base includes a rectangular frame. The rectangular frame includes vertical bars on both sides in the width direction and horizontal bars on both sides in the length direction. The vertical bars and the horizontal bars are limited and connected through limit card slots and fixed. A plurality of adjustable diagonal bracing components are connected to the rectangular frame. The upper ends of the adjustable diagonal bracing components are connected to short column steel bars to stabilize the rectangular frame.
[0007] Preferably, limit card slots are respectively arranged at both ends of the vertical bars, and both ends of the horizontal bars are respectively limited and connected with the limit card slots and fixed.
[0008] Preferably, the adjustable diagonal bracing component includes an adjustable bolt, a top - tight limiting part connected to the upper end of the adjustable bolt, and a connecting ring connected to the lower end of the adjustable bolt. The connecting ring is connected to the rectangular frame.
[0009] Preferably, the adjustable bolt is a flower basket bolt or a positive and reverse thread adjusting bolt, and the top - tight limiting part is a "figure - eight" limiting bar.
[0010] Beneficial Effects: The utility model provides a secondary grouting support device for an embedded steel column base, which has the advantages of simple structure, convenient material collection on the construction site, convenient construction, high construction efficiency, high stability, not easy to displace and bulge after demolition, and good forming effect.

[0015] Reference numerals in the figure: vertical rod 1; cross rod 2; limit card slot 3; adjustable bolt 41; top-tightening limit piece 42; connecting ring 43; short column steel bar 5. Specific embodiments
[0016] Next, with reference to the accompanying drawings, a specific embodiment of the present utility model will be described in detail, but it should be understood that the protection scope of the present utility model is not limited by the specific embodiments.
[0017] Example 1: As Figure 1-2 shown, the embedded steel column footing secondary grouting support device provided by the embodiment of the present utility model includes a rectangular frame. The rectangular frame includes vertical rods 1 on both sides in the width direction and cross rods 2 on both sides in the length direction. The vertical rods 1 and the cross rods 2 are limited and connected through the limit card slots 3 and fixed. A plurality of adjustable diagonal bracing assemblies 4 are connected to the rectangular frame. The upper ends of the adjustable diagonal bracing assemblies 4 are connected to the short column steel bars 5 to stabilize the rectangular frame.
[0018] Specifically, the vertical rods 1 and the cross rods 2 can be hollow square tubes. Limit card slots 3 are respectively arranged at both ends of the vertical rod 1. The two ends of the cross rod 2 are respectively limited and connected with the limit card slots 3 and fixed. The fixing method can be bolt fixing, that is, bolts are provided on the limit card slots 3, and bolt holes matched with the bolts are provided at the corresponding positions at both ends of the cross rod 2, so that it can be stably and detachably connected. The detachable connection is convenient for the removal of the rectangular frame and enables it to be recycled; of course, it can also be fixedly connected by welding. When the welded connection is removed, cutting is required, which may not be convenient for recycling.
[0019] Specifically, the adjustable diagonal bracing assemblies 4 can be arranged at the four corners of the rectangular frame. The adjustable diagonal bracing assembly 4 includes an adjustable bolt 41, a top-tightening limit piece 42 connected to the upper end of the adjustable bolt 41, and a connecting ring 43 connected to the lower end of the adjustable bolt 41. The connecting ring 43 is connected to the rectangular frame. The adjustable bolt 41 is a flower basket bolt or a positive and negative thread adjusting bolt. The top-tightening limit piece 42 is a "figure-eight" limit rib. Adjust the adjustable bolt 41 so that the "figure-eight" limit rib tightly abuts against the short column steel bar 5 to stabilize the rectangular frame.
[0020] Working principle or usage method of the present utility model:
[0021] Step 1: Especially in combination with Figure 3As shown, during installation, firstly, a rectangular frame is made according to the installation position of the steel structure and the design size of the steel structure column foot, that is, vertical bars 1 and horizontal bars 2 of corresponding sizes are made, and a release agent is applied on the contact surface, and then they are enclosed at the bottom of the steel structure to form a rectangular frame, and connected to the adjustable diagonal brace assembly 4, and the adjustable bolts 41 are adjusted to make the "eight-shaped" limiting ribs tightly against the short column steel bars 5 to stabilize the rectangular frame and complete the installation of the device.
[0022] Step 2: After installation, high-strength grouting material is injected into the device, and the grouting material is automatically formed into a rectangular column foot until the height of the grouting material reaches the design elevation, thereby completing the secondary grouting of the steel structure column foot; after the grouting material is properly solidified, the adjustable diagonal brace assembly 4 is removed, that is, the adjustable bolt 41 separates the "eight-shaped" limit reinforcement from the short column reinforcement 5, and then the rectangular frame is removed.
[0023] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
