Safety protective fence for building construction

Abstract

The utility model discloses a safety protective fence for building construction. The fence has the advantages that when the fence is used, after the two stand columns are fixed, only the inserting blocks on the two sides of the fence plate need to be placed in the inserting plates, the inserting plates can move downwards under the self-weight effect of the fence plate, and when the inserting plates move downwards, the pressing plates can be driven to move downwards by means of the sliding strips and the connecting columns; when the pressing plate moves downwards, the wedge-shaped block on the linkage plate is inserted into the wedge-shaped groove in the inserting block through the groove by means of the connecting rod so as to limit the enclosure plate, and when the enclosure plate needs to be disassembled, the enclosure plate only needs to be lifted to enable the wedge-shaped block to be separated from the wedge-shaped groove, so that the enclosure plate can be conveniently disassembled. Limiting of the enclosure plate is achieved through the dead weight of the enclosure plate, the tedious operation of manually screwing bolts for limiting is omitted, and therefore the installation efficiency of the enclosure plate is higher, and the construction progress cannot be delayed.

Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a safety guardrail for building construction. Background Art

[0002] Safety guardrails used in construction are also called foundation pit side fences. They are essential protective tools for protecting construction safety. There are usually two main types of foundation pit fences used in construction. They are mesh foundation fences and standpipe foundation pit fences. Mesh foundation pit fences are cheaper than standpipe foundation pit fences, have low cost and have visual functions, and are generally composed of enclosures and columns.

[0003] The existing places where fences and columns are connected are provided with installation holes, and construction workers connect fences and columns with screws. Since fences and columns are used in large numbers, the number of screws required to be installed is also relatively large, so it will consume a lot of time to install and disassemble the guardrail, affecting construction efficiency.

[0007] The utility model is realized through the following technical scheme: the utility model proposes a building construction safety guardrail, including a column, two quick locking mechanisms are symmetrically installed on the two side walls of the column, and a fencing plate is installed between two adjacent columns. The quick locking mechanism includes an insert block symmetrically installed on the two side walls of the fencing plate, a wedge-shaped groove arranged on one side wall of the insert block, and the quick locking mechanism also includes an insert plate symmetrically installed on the two side walls of the column, two slide bars symmetrically installed on one side wall of the insert plate, a slide groove arranged on the column and matching with the slide bar, a connecting column installed on one end of the slide bar away from the insert plate, a pressure plate installed on one end of the connecting column away from the slide bar, a connecting rod installed on one side wall of the pressure plate, a linkage plate installed on one end of the connecting rod away from the pressure plate, a wedge block installed on the side wall of the linkage plate facing away from the connecting rod, a groove arranged on the side wall of the insert plate facing the wedge block, a slide bar installed in the middle of the bottom end of the insert plate, a spring installed at the bottom end of the insert plate and located outside the slide bar, and a support plate installed on the column and connected to the bottom end of the spring.

[0008] Furthermore, the insert block is connected to the enclosure plate by bolts, the wedge-shaped groove is formed on the insert block, and the bottom of the wedge-shaped groove is an inclined structure.

[0009] By adopting the above technical solution, the insert block can be reliably installed and fixed on the enclosure plate. The insert block is the main component for realizing the rapid installation of the enclosure plate.

[0010] Furthermore, the slide bar is connected to the plug plate by bolts, the slide bar is welded to the connecting column, and the connecting column is welded to the pressure plate.

[0011] By adopting the above technical solution, the slide bar can ensure that when the plug board is inserted into the plug board, the plug board can be easily moved downward relative to the column.

[0012] Furthermore, the connecting column penetrates through the side wall of the slide slot and is slidably connected to the side wall of the slide slot, and the position of the linkage plate and the connecting column in the column is a hollow structure.

[0013] By adopting the above technical solution, the slide bar will drive the pressing plate to move downward with the help of the connecting column while moving downward.

[0014] Furthermore, one end of the connecting rod is hinged to the pressure plate, and the other end of the connecting rod is hinged to the linkage plate.

[0015] By adopting the above technical solution, the connecting rod will extend the wedge block out of the side wall of the column while the pressure plate moves downward, so as to insert the wedge block into the wedge groove.

[0016] Furthermore, the wedge block is welded to the linkage plate, and the bottom of the wedge block is also an inclined surface structure, and the inclined surface structure at the bottom of the wedge block matches the inclined surface structure at the bottom of the wedge groove.

[0017] By adopting the above technical solution, after the wedge block and the wedge groove cooperate to limit the position, the enclosure plate can be reliably installed between the two columns.

[0018] Furthermore, the sliding rod passes through the support plate and is slidably connected to the support plate, and the spring is welded to the support plate and the plug plate.

[0019] By adopting the above technical solution, the spring is mainly used to realize the automatic resetting of the plug plate and the wedge block when the baffle plate is lifted.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] In order to solve the problem that the existing enclosures and columns are connected at the places where installation holes are provided, the construction workers connect the enclosures and columns by screws. Since the number of enclosures and columns used is large, the number of screws required to be installed is also relatively large, which will consume a lot of time for installation and disassembly of the guardrail, affecting the construction efficiency. When the utility model is used, after the two columns are fixed, it is only necessary to place the plug blocks on both sides of the enclosure plate in the plug plate, and the plug plate can be moved down under the action of the deadweight of the enclosure plate. When the plug plate moves down, it will drive the pressure plate to move down with the help of the sliding bar and the connecting column, so that during the downward movement of the pressure plate, the connecting rod can be used to The wedge block on the linkage plate is inserted into the wedge groove in the insert block through the groove to achieve the limitation of the enclosure plate. When the enclosure plate needs to be removed, the enclosure plate only needs to be lifted to separate the wedge block from the wedge groove, so that the enclosure plate can be conveniently disassembled. Because in the above-mentioned assembly method, the limitation of the enclosure plate is achieved by utilizing the dead weight of the enclosure plate, which eliminates the tedious operation of manually tightening the bolts for limitation, thereby making the installation efficiency of the enclosure plate higher. At the same time, when dismantling, the wedge block can be reset by relying on the rebound effect of the spring after the enclosure plate is lifted, which also facilitates the rapid removal of the enclosure plate after use.
