Background
In underground civil air defense buildings, large-volume radiation-proof concrete shear walls are often involved; under the requirement of neutron radiation prevention, the concrete shear wall is required to have certain thickness so as to effectively block radiation, the working section of the common radiation-proof concrete wall needs to be formed in one step without leaving cold joints, and under the dual functions of bearing and radiation, the thickness of the shear wall is generally very thick, so that the spatial arrangement of a building is influenced, the hydration heat is large in the later forming period, cracks are easily generated, and the safety of the structure and the function of neutron radiation prevention are adversely affected.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a be arranged in underground explosion-proof anti-corrosion neutron radiation prevention UHPC shear force wall to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: an UHPC shear wall used for underground explosion-proof corrosion-resistant neutron radiation prevention, which is constructed from the outside to the inside in sequence: the first barium sulfate mortar layer, the UHPC cast-in-place layer, the I-steel, the second barium sulfate mortar layer, the keel layer and the dry hanging lead plate.
Preferably, the UHPC shear wall for underground explosion-proof, erosion-resistant and neutron radiation prevention is provided, wherein the UHPC layer is cast in situ between the first barium sulfate mortar layer and the second barium sulfate mortar layer.
Preferably, the UHPC shear wall for underground explosion-proof erosion resistance and neutron radiation prevention, which is provided by the application, is characterized in that the dry hanging lead plate is arranged on the inner side of the wall body, and the dry hanging lead plate is connected with the wall body through the keel.
Preferably, the UHPC shear wall for underground explosion-proof erosion-resistant neutron radiation prevention is provided, wherein the thicknesses of the first barium sulfate mortar layer and the second barium sulfate mortar layer are both 3-5mm; the thickness of the UHPC cast-in-situ layer is 8mm-10mm.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a shear force wall is used for secret people's air defense, under the prerequisite that reaches same shielding radiation effect, can effectively reduce wall body thickness, saves usage space.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: the cast-in-place steel pipe comprises a first barium sulfate mortar layer 1, a UHPC cast-in-place layer 2, I-steel 3, a second barium sulfate mortar layer 4, a keel layer 5 and a dry hanging lead plate 6.
Detailed Description
