Abstract
The utility model discloses a kind of pre-buried channel flow anti-slip T-type spring bolts, including T-bolt ontology compatible with pre-buried channel flow, T-bolt ontology is connected by screw rod and bolt head and is formed, it is vertically fixed with top pressure spring in the bolt head upper surface middle part of T-bolt ontology, the outer end of top pressure spring is the cirque structure being closed.The utility model advantage is simple in structure, simple installation, saves manpower, versatile, shortens construction period, reduces project cost, construction efficiency greatly improves.It when T-bolt ontology is installed in pre-buried channel flow, is supported and is fixed by the top pressure spring being fixed on bolt head, avoid sliding downwards along pre-buried channel flow when unclamping T-bolt ontology；In addition when T-bolt ontology encounters boss along pre-buried channel flow sliding, top pressure spring can be compressed, and the cirque structure that outer end is closed can ensure to slide smooth, avoid the occurrence of stuck phenomenon, it is ensured that normal installation.
Description
Technical field
The utility model is related to the pre-buried channel flows in the piping lane engineering of city, more particularly, to a kind of pre-buried channel flow anti-slip T
Type spring bolt.
Background technology
The whole nation more and more uses pre-buried channel flow technology in building city piping lane engineering at present, i.e., at piping lane scene
It pours, be implanted into pre-buried channel flow before prefabricated reinforced concrete, cross that top, that installation provides is safe efficient, convenient for equipment and equipment
Total solution.
Toothed T-bolt is used in existing pre-buried channel flow more（As shown in Figure 1）, when mounted first by T-bolt
Bolt head be horizontally inserted into pre-buried channel flow, be then rotated by 90 °, the teeth face of bolt head and pre-buried channel flow inner wall made to fit i.e.
It can；Since there are the gaps 4 ~ 6mm between toothed T-bolt and corresponding pre-buried channel flow（Convenient for T-bolt connected device edge
Pre-buried channel flow slides）, therefore in the pre-buried channel flow vertically installed when release T-bolt, T-bolt can be immediately along pre-buried channel flow
It slides downwards, required position can not be rested on, therefore scene needs more people to co-operate the installation for completing component, both wastes people
Power, and waste time.
In addition, existing, also one is install spring leaf additional on the bolt head of T-bolt（As shown in Figure 2）, pass through spring
Piece flexibly supports to fix the installation site of T-bolt；Though this kind of structure can prevent T-bolt slide downward, built-in groove
Road be when mounted first riveted with anchor pole, be embedded into again later within the walls, thus can pre-buried channel flow inner wall formation 2 ~
The boss of 2.5mm（The rock bolt head of protrusion）, when the T-bolt with spring leaf slides in pre-buried channel flow, spring leaf
Position will be stuck at boss, and what be can not be successfully reciprocatingly slides, and stuck phenomenon occur, must will be with spring leaf when practical operation
T-bolt takes out, and around the boss inside pre-buried channel flow, reselects installation site, time-consuming.
Invention content
The utility model aim is to provide a kind of simple in structure, sliding smoothly pre-buried channel flow anti-slip T-type spring spiral shell
Bolt.
To achieve the above object, the utility model can take following technical proposals：
Pre-buried channel flow anti-slip T-type spring bolt described in the utility model, including T-type spiral shell compatible with pre-buried channel flow
Bolt ontology, the T-bolt ontology is connected by screw rod and bolt head and is formed, in the bolt head upper surface of the T-bolt ontology
Middle part is vertically fixed with top pressure spring, and the outer end of the top pressure spring is the cirque structure being closed.
The diameter of the top pressure spring is less than the bolt head long side length of the T-bolt ontology, a diameter of 13mm.
The height of the top pressure spring is 5mm.
The utility model advantage is simple in structure, simple installation, saves manpower, versatile, shortens construction period, drop
Low project cost, construction efficiency greatly improve.When T-bolt ontology is installed in pre-buried channel flow, by being fixed on bolt head
On top pressure spring support fix, avoid unclamp T-bolt ontology when slid downwards along pre-buried channel flow；In addition when T-bolt sheet
When body encounters boss along pre-buried channel flow sliding, top pressure spring can be compressed, and the cirque structure that outer end is closed can ensure
It slides smooth, avoids the occurrence of stuck phenomenon, it is ensured that normal installation.
Description of the drawings
Fig. 1, Fig. 2 are the structural schematic diagrams of existing T-bolt.
Fig. 3 is the structural schematic diagram of the utility model.
Fig. 4 is the vertical view of Fig. 3.
Fig. 5 is the use state reference chart of Fig. 3.
Specific implementation mode
As shown in Fig. 3,4,5, pre-buried channel flow anti-slip T-type spring bolt described in the utility model, including with built-in groove
The compatible T-bolt ontologies 1 of road a, T-bolt ontology 1 are connected by screw rod and bolt head and are formed, when installation, by bolt head card
Loaded in pre-buried channel flow a, the notch of screw rod from pre-buried channel flow a extend, and ensure that T-bolt ontology 1 can be along pre-buried channel flow a long
Degree direction reciprocatingly slides；It is vertically fixed with top pressure spring 2, top pressure spring 2 in the bolt head upper surface middle part of T-bolt ontology 1
It can be directly welded in bolt head upper surface, annular fixing slot can be also opened up on bolt head upper surface, top pressure spring 2 is fastened in ring
In shape fixing slot；In addition, a diameter of 13mm of top pressure spring 2, is less than the bolt head long side length of T-bolt ontology 1, is ensureing
The smooth sliding of T-bolt ontology 1 is not influenced while top pressure spring 2 fixes stability again；And the height of top pressure spring 2 is
5mm had not only ensured that the elastic anchorage force of top pressure spring 2 can be stablized and has fixed T-bolt ontology 1, but also will not be propped up due to elasticity
Support force is excessive and the sliding of T-bolt ontology 1 is caused to have some setbacks, and makes the installation of T-bolt ontology 1 and more convenient to use, passes through T
The external connection workpiece c slide that type bolt body 1 connects is more smooth.
To avoid the boss of pre-buried channel flow a slot bottoms（Pre-buried channel flow a is first to be riveted with anchor pole b when pre-buried, Zhi Houzai
It is embedded within the walls, therefore boss can be formed in pre-buried channel flow a slot bottoms）Block, the outer end of top pressure spring 2 are formed to top pressure spring 2
Portion is the cirque structure being closed, and it is smooth to ensure that T-bolt ontology 1 slides, avoids the occurrence of stuck phenomenon, it is ensured that external connection work
The installation of part c and normal use.
In addition, anti-slip T-type spring bolt described in the utility model is not only applicable to pre-buried channel flow, additionally it is possible to be adapted to aluminium
The various occasions using anti-slip T-type spring bolt such as alloy profile assembling.
