Description

Embedded part of protective barrier

Technical Field

The utility model relates to a guardrail fixing device technical field specifically is a prevent guardrail bar built-in fitting.

Background

The most common mode of foundation ditch periphery, floor limit installation guardrail is behind the concreting at present, punches again, and installation expansion bolts installs the guardrail at last, and it takes time to take more trouble, influences guard rail installation time, and punches and install expansion bolts and all can influence the wholeness of concrete to the concrete, and the intensity that reduces the concrete easily leads to appearing the crack or drops, has reduced the security after the guardrail installation.

SUMMERY OF THE UTILITY MODEL

For solving the not enough of prior art, the utility model provides a guard rail built-in fitting, this device can install the guardrail in the cast concrete through the mode installation guardrail of pre-buried connecting piece, and need not punch, can not destroy the good concrete of pouring.

The utility model discloses a realize above-mentioned purpose, realize through following technical scheme:

the utility model provides a guard rail built-in fitting, includes the support, the anterior and the rear portion of support top surface both sides are first bolt of fixed mounting respectively, the periphery of first bolt is screw-thread fit installation several nut respectively.

The bottom of support is equipped with leveling mechanism, leveling mechanism includes the second bolt, the screw is seted up respectively to the bottom surface four corners of support, the screw is downthehole respectively screw-thread fit installation second bolt.

And the bottom surfaces of the second bolts are respectively fixedly provided with a disc.

The number of the nuts on any one first bolt is 3.

The support comprises two cross rods which are arranged in parallel, and the two cross rods are fixedly connected by a plurality of connecting rods.

The cross bar is made of a threaded steel bar.

Contrast prior art, the beneficial effects of the utility model are that:

this device is with 1 direct pre-buries of support in the concrete when using, and the guardrail can be installed between after 1 is fixed to support, need not wait the concrete setting after to punch the installation expansion bolts to the concrete again, the wholeness of guarantee concrete, and reduced the installation step of guardrail, improve constructor's work efficiency.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

The embodiment is as follows: embedded part of protective railing

As shown in fig. 1-5, a guard rail embedded part has a specific structure comprising:

support 1, 1 level setting of support, the front portion and the rear portion of 1 top surface both sides of support are first bolt 2 of fixed mounting respectively, the equal vertical setting of first bolt 2, the periphery of first bolt 2 is screw-thread fit installation several nut 3 respectively.

The bottom of support 1 is equipped with leveling mechanism, leveling mechanism includes second bolt 4, screw 5 is seted up respectively to the bottom surface four corners of support 1, screw cooperation installation second bolt 4 is respectively in the screw 5. This structural design is when using, through rotating the second bolt 4 of different positions, can adjust corresponding second bolt 4 respectively to the screw 5 that is connected with it the length that stretches out outward, realizes the support to support 1 through mutually supporting between each second bolt 4 to realize the leveling of support 1 when placing on ground, improve the application range of this device.

And the bottom surfaces of the second bolts 4 are respectively fixedly provided with a disc 6. Disc 6 can increase the area of contact between second bolt 4 and the ground, improves the stability when this device is placed, and simultaneously when pouring, disc 6 can realize better holding power to the concrete, further anchor support 1 through mutually supporting between disc 6, the second bolt 4 to improve the reliability of this device.

The number of the nuts 3 on any one first bolt 2 is 3. When using, with the preformed hole on the guardrail base suit respectively on corresponding first bolt 2 back, two corresponding nuts 3 that lie in the below on same first bolt 2 are used for supporting the guardrail base, and the nut 3 that lies in the top is used for fixed locking guardrail base.

The support 1 comprises two cross rods 1-1 which are arranged in parallel, the two cross rods 1-1 are fixedly connected through a plurality of connecting rods 1-2, and two ends of each connecting rod 1-2 are respectively and fixedly connected with the inner sides of the corresponding cross rods 1-1. When concrete is poured, the cross rod 1-1 and the connecting rod 1-2 can be wrapped by the concrete respectively, so that the support 1 is not easy to fall off in the concrete, and the stability of the device is improved.

The cross rod 1-1 is made of twisted steel. The structural design can increase the contact area between the cross rod 1-1 and the concrete, so that the concrete can be embedded into the thread of the cross rod 1-1, the support 1 is further prevented from falling off in the concrete, and the reliability of the device is improved.

This device is when using, the user is in the reinforcement process before concrete placement, can directly tie up support 1 and fix on steel framework, thereby make support 1 direct casting in the concrete, can be after support 1 is fixed directly install the guardrail before the cast concrete, install the guardrail base suit on corresponding first bolt 2, then fix the guardrail base through corresponding nut 3 centre gripping, can accomplish the installation of guardrail, need not wait that the concrete sets up the back and punch the installation expansion bolts to the concrete again, the installation step of guardrail has been reduced, avoided the concrete promptly to be destroyed and can improve constructor's work efficiency again.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
