Description
Technical Field
The utility model relates to a construction technical field of steel construction specifically is a steel construction pre-buried rag bolt's fixing device.
Background
In steel construction engineering, generally be connected with the basis through rag bolt, and for guaranteeing rag bolt's firm, rag bolt is pre-buried in the basis, and it is accurate pre-buried to the installation quality influence of upper portion steel construction great. In actual construction, the accuracy of embedding the foundation bolts is difficult to guarantee. According to the requirements of the specification GB50205-2001 of the construction quality acceptance of the steel structure engineering and the specification GB 50755-2012 of the construction of the steel structure engineering, the requirement of the error displacement of the foundation bolt does not exceed 5mm. Therefore, the embedded construction of the foundation bolt is a key process with high construction precision requirement.
At present, foundation bolts are mainly welded through steel bars to form a supporting frame, and the prefabricated foundation bolts are fixed through welding. And a support frame is formed by welding angle steels, and the prefabricated foundation bolts are fixed by welding. The two methods have some defects that 1, the existing positioning structure is inconvenient to install, needs to be welded and fixed on site during site construction, increases workload and manual input, and prolongs construction period. 2. The existing positioning structure is not stable enough for installing foundation bolts, after the foundation bolts are positioned, when steel column foundation concrete is poured, the lower parts of the foundation bolts are easy to deviate due to the impact effect of the concrete and the vibration influence during vibration, so that the plane positions and the levelness of the foundation bolts are deviated, and the installation quality of an upper steel structure is seriously influenced by 3. The existing positioning structure is not accurate enough for positioning and installing the foundation bolts and is inconvenient to adjust.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned defect, provide one kind adjustable, and can assemble fixed prefabricated rag bolt's device fast. The device can be great solved because the cushion cap height is different, and lead to the high complicated various scheduling problem of buried bolt in advance, reduce the welding number of times, reduce construction period.
In order to achieve the above object, the present invention is realized as follows:
a fixing device for steel structure embedded foundation bolts comprises four bottom supports (11), four supporting vertical rods (4), four connecting bolts (5) and four supporting top frames (6), wherein the four bottom supports (11) are respectively arranged at the bottoms of the supporting vertical rods (4), the number of the supporting vertical rods (4) is also four, and four corner cakes arranged on the supporting top frames (6) are connected with the supporting top frames (6) through the connecting bolts (5); the bottom support (11) comprises a triangular foot support (1), a screw rod (2) and a fixed adjuster (3), the screw rod (2) is connected with a support vertical rod (4) through the fixed adjuster (3), and the triangular foot support (1) is sleeved on the screw rod (2).
When this transposition is used, get into simultaneously and install when cushion cap bottom reinforcing bar is placed, it not only can be the certain protective layer of bottom plate reinforcing bar cushion cap, and the cushion cap reinforcing bar has strengthened the stability of collet through self gravity, after cushion cap bottom reinforcing bar board is pricked and is accomplished, support pole setting and support top frame through screw rod and bolted connection, can carry out final welding with prefabricated rag bolt and disc in these installation completion backs, reach a stable structure, place column base reinforcing bar and stirrup, can carry out pre-buried pouring after the reinforcing bar board is pricked and is accomplished.
Compared with the traditional mode, the device has the characteristics of adjustability, stability, convenience in installation and the like, and is suitable for the complicated and various height conditions of the field bearing platform and the complicated and complicated situation of the field embedded foundation bolts. The device not only can significantly reduce welded work load, and is very accurate to the control of site accuracy moreover, and the collet with adjustable carries out the overlap joint with the reinforcing bar and has guaranteed the stable effect of this structure.

Detailed Description
The invention is further illustrated by the following specific examples.
As shown in fig. 1, the fixing device for the steel structure embedded foundation bolts comprises four bottom supports (11), four supporting vertical rods (4), connecting bolts (5) and four supporting top frames (6), wherein the four bottom supports (11) are respectively arranged at the bottoms of the supporting vertical rods (4), the number of the supporting vertical rods (4) is also four, and four corner cakes arranged on the supporting top frames (6) are connected with the supporting top frames (6) through the connecting bolts (5); the bottom support (11) comprises a triangular foot support (1), a screw rod (2) and a fixed adjuster (3), the screw rod (2) is connected with a support vertical rod (4) through the fixed adjuster (3), and the triangular foot support (1) is sleeved on the screw rod (2).
When this transposition is used, get into simultaneously and install when cushion cap bottom reinforcing bar is placed, it not only can be the certain protective layer of bottom plate reinforcing bar cushion cap, and the cushion cap reinforcing bar has strengthened the stability of collet through self gravity, after cushion cap bottom reinforcing bar board is pricked and is accomplished, support pole setting and support top frame through screw rod and bolted connection, can carry out final welding with prefabricated rag bolt and disc in these installation completion backs, reach a stable structure, place column base reinforcing bar and stirrup, can carry out pre-buried pouring after the reinforcing bar board is pricked and is accomplished.
Compared with the traditional mode, the device has the characteristics of adjustability, stability, convenience in installation and the like, and is suitable for the complicated and various height conditions of the field bearing platform and the complicated and complicated situation of the field embedded foundation bolts. The device not only can greatly reduce the welding workload, but also can control the on-site precision very accurately, and the adjustable overlapping of the bottom support and the reinforcing steel bars ensures the stable effect of the structure.
