Description
Technical Field
The utility model relates to a construction field is a foundation ditch construction protection guardrail bearing structure.
Background
In the foundation pit construction process, the constructor approaches or closes on the construction operation of foundation pit edge, all has the danger of falling, in order to guarantee constructor personal safety, must set up all around closing on the foundation pit and enclose anti-falling measures such as fender guardrail. At present, adopt to establish interim rail as the guardrail to great foundation ditch construction engineering mostly, interim rail is for the ease of demolising the removal, and its weight is often lighter, when meetting strong wind weather, because of the installation insecure, appears collapsing easily, therefore has the risk of falling, and in serious time, can cause life danger to foundation ditch bottom construction operation personnel even. For this reason, the support structure of the existing construction temporary guard rail is to be improved.
Disclosure of Invention
For overcoming the above-mentioned not enough, the utility model aims at providing a foundation ditch construction protection guardrail bearing structure to this field, make it solve current guardrail of the same kind and support firmness and stability not good enough, meet strong wind weather and easily collapse, have the technical problem of foundation ditch construction potential safety hazard. The purpose is realized by the following technical scheme.
The utility model provides a foundation ditch construction protection guardrail bearing structure, this protection guardrail bearing structure include the support steel pipe as protection guardrail partly, support steel pipe vertical support in foundation ditch manger plate bank top surface. The foundation pit water retaining ridge is structurally characterized in that embedded joint bars matched with the support steel pipes in an inserted mode are arranged in the foundation pit water retaining ridge, namely, part of the embedded joint bars are embedded in the foundation pit water retaining ridge in advance, the other part of the embedded joint bars is exposed out of the top surface of the foundation pit water retaining ridge and is inserted and supported with the support steel pipes, at least two auxiliary reinforcing steel bars forming auxiliary supports for the support steel pipes are uniformly welded on the outer side of each support steel pipe along the circumferential direction, and the auxiliary reinforcing steel bars are supported on the foundation pit water retaining ridge. Through above-mentioned structure, utilize the pre-buried dowel bar of foundation ditch manger plate bank to realize effectively supporting the protection guardrail to improve the stability and the firmness that protection guardrail supported, be difficult for collapsing because of the strong wind influence, ensure foundation ditch construction's security. And add supplementary reinforcing bar, be favorable to the increase to support the contact fulcrum of steel pipe and foundation ditch manger plate bank to further improve the support stability who supports the steel pipe, be difficult for empting. Besides, the embedded joint bars not only play a role in temporarily supporting and fixing the protective guardrails, but also facilitate subsequent arrangement and construction operation of the reinforcing steel bars during subsequent heightening construction of the water retaining ridge of the foundation pit.
And before the auxiliary steel bars are welded with the support steel pipes, part of the auxiliary steel bars are pre-buried in the foundation pit water retaining ridge. Through this structure, further improve the steadiness to supporting the steel pipe, support the steel pipe and be difficult for deviating from pre-buried dowel steel.
And the auxiliary steel bars and the support steel pipes are locally welded. Through this structure, the later stage of being convenient for is cut and is welded and dismantle.
The bottom of the auxiliary reinforcing steel bar is welded with a base supported on the top surface of the foundation pit retaining ridge, and the base is used for supporting the steel pipe to form an auxiliary support. Through this structure, utilize the support of base, further improve the support stability who supports the steel pipe, be difficult for rocking.
The base is provided with an inner hole penetrating through the embedded joint bar, and the base is welded before the auxiliary steel bar, the inner hole is welded and fixed with the embedded joint bar. Through this structure, realize the firm fixed of pre-buried dowel steel with the support steel pipe. When needing to demolish, only need throw off the welding of auxiliary reinforcement and base, can realize supporting the steel pipe and deviate from for pre-buried dowel, it is comparatively convenient to operate.
The utility model discloses overall structure is comparatively simple, and the installation and construction is comparatively convenient, and the whole support of protection guardrail is comparatively stable, reliable, the security of guarantee foundation ditch construction, and it is fit for the bearing structure who regards as all kinds of protection guardrails to use, or the improvement of homogeneous structure.

Fig. 2 is a schematic sectional view of a modification of fig. 1.
Fig. 3 is a schematic sectional structure view of a second modification of fig. 1.
The sequence numbers and names in the figure are: 1. the foundation pit supporting structure comprises a supporting steel pipe, 2, embedded joint bars, 3, auxiliary steel bars, 4, a foundation pit water retaining ridge, 5 and a base.
Detailed Description
The invention will now be further described with reference to the accompanying drawings.
As shown in figure 1, the foundation pit construction protection guardrail supporting structure comprises a supporting steel pipe as part of a protection guardrail, namely the protection guardrail takes the supporting steel pipe as a vertical support and is connected with a transverse support by matching with a scaffold connecting piece to form a protection guardrail which is crossed transversely and longitudinally. Support steel pipe vertical stay in foundation ditch manger plate bank top surface, specifically do: be equipped with in the foundation ditch manger plate bank with support steel pipe grafting complex pre-buried dowel steel, the part of pre-buried dowel steel is pre-buried in the foundation ditch manger plate bank promptly, and another part exposes in foundation ditch manger plate bank top surface and grafting supports above-mentioned support steel pipe, supports the steel pipe outside and welds two auxiliary reinforcement that form auxiliary stay to supporting the steel pipe along circumference equipartition, and auxiliary reinforcement supports in foundation ditch manger plate bank. The supporting structure is uniformly arranged along the foundation pit water retaining ridge, so that stable support for the protective guardrail can be formed.
As shown in fig. 2, in order to improve the firmness of the support steel pipe, before the auxiliary steel bar is welded to the support steel pipe, part of the auxiliary steel bar is embedded in the water retaining sill of the foundation pit. And the auxiliary steel bars and the support steel pipes are locally welded so as to facilitate later dismantling operation.
As shown in fig. 3, the bottom of the auxiliary reinforcing steel bar may also be welded with a base supported on the top surface of the retaining sill of the foundation pit, that is, the base forms an auxiliary support for the supporting steel pipe. Further, the base is provided with an inner hole penetrating through the embedded joint bar, and the inner hole and the embedded joint bar are welded and fixed before the auxiliary steel bar is welded on the base. Through this structure, realize the indirect fixed of pre-buried dowel steel with supporting the steel pipe. When later stage need will support steel pipe and pre-buried dowel bar and throw off, only need with the splice between auxiliary reinforcement and the base cut weld can, it is comparatively convenient to operate.
The above contents are intended to illustrate the technical means of the present invention, and do not limit the technical scope of the present invention. Obvious modifications or substitutions for the present invention by a person of ordinary skill in the art in combination with the prior art also fall within the protection scope of the present invention.
