Abstract
The invention discloses a U-shaped building embedded part and a construction method of an anchoring component applying the U-shaped building embedded part. The embedded part comprises a U-shaped bolt, two connecting sleeves and a reinforcing steel bar; the U-shaped bolt and the connecting sleeves are connected through threads, and the reinforcing steel bar and the U-shaped bolt are welded, so that the U-shaped bolt is prevented from being deformed in the carrying process. When embedding in pouring construction is conducted, the ends of the connecting sleeves abut against a whole formwork, holes do not need to be preformed in the whole formwork, the slurry leakage phenomenon cannot occur in the pouring process, and later formwork stripping is easy; in addition, accessory equipment is connected with the sleeves of the U-shaped embedded part through bolts, when the accessory equipment fails, the accessory equipment can be maintained and replaced by screwing down the connecting bolts, and therefore concrete structure ancillary facilities are greatly convenient to maintain and replace.
Description
Technical field
The invention belongs to build pre-buried structure part, in particular to a kind of U-shaped building built-in part and the construction method of anchorage element thereof.
Background technology
At present, during concrete bridge structure construction, it will usually use anchoring built-in fitting.Existing anchoring built-in fitting mostly is U bolt, along with being widely used of U bolt, its drawback gradually highlights, it is mainly manifested in: 1, owing to present stage concrete bridge structure uses Overall Steel Formwork to construct in a large number, and the end of pre-buried U bolt needs to firstly appear out from concrete bridge structure surface, need perforate in advance at corresponding Overall Steel Formwork, so may result in the phenomenon that spillage occurs in filling concrete work progress, thus bring difficulty to demoulding steel formwork；Even if 2 demoulding steel formworks successes, spill the U bolt two ends of concrete structural surface and collide with owing to being highly prone in work progress, cause its external screw thread to be less able to use；3, due to pre-buried U bolt expose concrete bridge structure surface end damage after cannot change, also cannot keep in repair replacing after causing the affiliated facility being fixed on built-in fitting end to break down.
Summary of the invention
For solving above-mentioned technical problem, the invention provides a kind of U-shaped building built-in part and the construction method of anchorage element thereof, the spillage that existing U bolt built-in fitting in use brings, the problem that the demoulding is difficult, U bolt built-in fitting availability is low and affiliated facility later period maintenance is difficult can be prevented effectively from.
For achieving the above object, the technical scheme is that
A kind of U-shaped building built-in part, including U-bolt and two branch sleeves, two ends of described U-bolt are provided with external screw thread, and its difference is: described branch sleeve is provided with female thread, and two ends of described U-bolt and branch sleeve are threaded connection.
In technique scheme, two ends of described U-bolt are crossed with stiffener.
In technique scheme, described branch sleeve is tubular structure, and the lateral wall of described branch sleeve is along the circumferential direction provided with annular recess, and described branch sleeve lateral wall is axially symmetric is provided with two flat horizontal surfaces.
In technique scheme, the external diameter of described branch sleeve is 1.5-4 times of the diameter of U-bolt.
The construction method of the anchorage element of above-mentioned U-shaped building built-in part, comprises the steps:
(1) template is made: according to design drawing and other technical data field fabrications fixing construction formwork；
(2) fixing built-in fitting: determine the installation site point of built-in fitting according to design drawing, integral mold plate is withstood in the end of built-in fitting upper joint sleeve cylinder, then built-in fitting is fixed on the steel reinforcement cage of xoncrete structure；
(3) cast concrete: completing concrete cast, vibration compacting, after making concrete setting, this built-in fitting is integral with concrete setting；
(4) form removal: form removal after concrete component has solidified, the concrete slag on cleaning anchorage element surface, make branch sleeve end expose anchorage element surface.
Beneficial effects of the present invention:
(1) by setting up a branch sleeve respectively at U-bolt two ends, change the connected mode of affiliated facility and built-in fitting, built-in fitting is without firstly appearing out from concrete structural surface in advance, corresponding Overall Steel Formwork is without perforate in advance, thus effectively prevent the spillage phenomenon in filling concrete work progress, also reduce the demoulding difficulty of Overall Steel Formwork after cast simultaneously；
(2) when pouring construction is pre-buried, the sleeve ends of designed U-shaped building built-in part withstands Overall Steel Formwork, and internal thread of sleeve can be avoided destroyed in work progress；
(3) being connected with the branch sleeve of U-shaped building built-in part by bolt due to auxiliary device, when auxiliary device breaks down, just can keep in repair replacing auxiliary device by backing out connecting bolt, the maintenance greatly facilitating xoncrete structure affiliated facility is changed；
(4) U-shaped building built-in part is rational in infrastructure, and processing is simple, connects fixed performance stable, can be widely applied to the installation of embedded parts of xoncrete structure.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the present invention；
Fig. 2 is the top view of the sleeve of the present invention；
In figure: U-bolt 1, branch sleeve 2, annular recess 21, flat horizontal surface 22, stiffener 3.
Detailed description of the invention
In order to be better understood from technical scheme, the present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, the U-shaped building built-in part of one provided by the present invention, including 1, two branch sleeves 2 of U-bolt and stiffener 3.
Two ends of described U-bolt 1 are provided with external screw thread；Described branch sleeve 2 is the tubular structure that lateral wall is along the circumferential direction provided with two annular recess 21, the lateral wall of branch sleeve 2 is axially symmetric is provided with two flat horizontal surfaces 22, branch sleeve 2 is provided with female thread, and the two ends of described U-bolt 1 are threaded connection with branch sleeve 2；Described stiffener 3 welds with the two ends 12 of U-bolt 1 respectively across two ends of U-bolt 1, the two ends of described stiffener 3.
A diameter of 20mm of described U-bolt 1, the external diameter of described branch sleeve 2 is 40mm, a diameter of 15mm of described stiffener 3.
The U-shaped building built-in part of the present invention is applied to the construction method of anchorage element, comprises the following steps:
(1) according to design drawing and other technical data field fabrications fixing construction formwork；
(2) the installation site point of built-in fitting is determined according to design drawing, at each installation site point, integral mold plate is withstood in the end of the branch sleeve 2 of U-shaped building built-in part prefabricated for batch production, by tied silk, U-bolt 1 and stiffener 3 are tied up on the steel reinforcement cage of xoncrete structure again, fixing built-in fitting；
(3) selecting suitable substrate concrete, and complete cast, note vibration compacting during cast, after making concrete setting, this built-in fitting is integral with concrete setting；
(4) form removal after concrete component has solidified, the concrete slag on cleaning anchorage element surface, make branch sleeve end expose anchorage element surface.
