Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, specifically a rain shelter suitable for the concrete pouring of precast box girders. Background Technology

[0002] The construction of the waterproof layer at the beam end of the precast box girder is greatly affected by weather factors. The concrete surface at the beam end must be dry when the waterproof layer is applied, otherwise the waterproof coating will easily peel off. At the same time, the freshly applied waterproof coating cannot be washed away by rainwater, otherwise it will cause pitting and drip marks on the surface, affecting the appearance quality of the precast beam.

[0003] Currently, waterproofing layer construction can only be carried out in rainless weather, especially in rainy and temperature-different environments on plateaus, which greatly restricts the construction quality and progress of precast beam yards. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0026] This utility model provides a rain shelter suitable for precast box girder concrete pouring. Please refer to [link / reference]. Figures 1-4The system includes a main frame 100 and connecting frames 200. A steel plate 110 is fixedly installed on the outer wall of the main frame 100, and a foam board 120 is fixedly bonded to the inner wall of the main frame 100. A crossbeam frame 130 is fixedly installed on the inner top of the main frame 100, and a baffle plate 140 is fixedly installed on the top of the crossbeam frame 130. Waterproof boards 150 are fixedly installed at both ends of the inner side of the main frame 100, and ventilation holes 160 are provided on the waterproof boards 150. Connecting frames 200 are fixedly installed on the inner wall of the main frame 100, and a base frame 210 is fixedly installed at the bottom of the two connecting frames 200. Casters 220 are connected to the bottom of the base frame 210. Specifically, the main frame 100 is constructed of several square tubes, which are welded together to form a stable support system. To ensure structural stability, the steel plate 110 serves as a windbreak and prevents rainwater from being blown onto the waterproof layer at the beam end. The foam board 120 facilitates heat insulation, reducing the impact of high temperatures on the interior. The ventilation holes 160 increase breathability and improve construction comfort. The crossbeam frame 130 provides support for the shielding plate 140. The tight connection between the steel plate 110, shielding plate 140, and waterproof board 150 effectively isolates rainwater and other water sources from interfering with the waterproof layer construction. The connecting frame 200 facilitates connection and fixation with the main frame 100, thereby facilitating the installation and positioning of the casters 220. The base frame 210 facilitates connection to the casters 220, which in turn facilitate the movement of the device, allowing for quick transfer and adjustment at different construction locations.

[0027] The front side wall of the steel plate 110 is equipped with a handle. Two handles are symmetrically arranged. Specifically, the handles facilitate pushing the device and moving the device.

[0028] The top of the shield 140 is provided with a vertical plate, which is fixedly connected to the top of the shield 140 by bolts. Specifically, the vertical plate helps to prevent rainwater on the shield 140 from flowing inward, thus facilitating the shielding.

[0029] The main frame 100 is formed by welding several square steel pipes, which facilitates the improvement of the support strength of the device. The structure is stable and durable and can be reused multiple times.

[0030] The steel plate 110 has openings to facilitate personnel entry and exit and work operations.

[0031] The waterproof membrane 150 is inclined, and the two waterproof membranes 150 are symmetrically arranged.

[0032] Combination Figures 1-4This embodiment provides a rain shelter suitable for precast box girder concrete pouring. The specific usage process is as follows: The main frame 100 is constructed from several square tubes, which are welded together to form a stable support system, ensuring structural stability. Steel plates 110 provide wind protection and prevent rainwater from being blown onto the waterproof layer at the beam ends. Foam boards 120 facilitate heat insulation, reducing the impact of high temperatures on the internal structure. Ventilation holes 160 increase the internal permeability of the device, improving construction comfort. The tight connection between the steel plates 110, the shielding plate 140, and the waterproof board 150 effectively isolates rainwater and other water sources from interfering with the waterproof layer construction, ensuring normal construction in rainy or high-temperature environments. Casters 220 facilitate the movement of the device, allowing for rapid transfer and adjustment at different construction locations.

[0033] Figures 3-4 The diagram shown is a structural schematic of a second embodiment of the rain shelter for precast box girder concrete pouring according to this utility model. Please refer to [link / reference]. Figures 3-4 Unlike the above-described embodiments, the base frame 210 has a mounting bracket 300 on its side wall. The mounting bracket 300 has a screw hole 310, a screw rod 320 is installed in the screw hole 310, a crank handle 330 is installed at the top of the screw rod 320, and a fixing plate 340 is installed at the bottom of the screw rod 320. The bottom of the fixing plate 340 is provided with an anti-slip pad 350. Specifically, the crank handle 330 facilitates the rotation of the screw rod 320. The rotation of the screw rod 320 generates a downward force, which presses the fixing plate 340 tightly against the ground, thereby achieving the purpose of fixing the position of the device. The anti-slip pad 350 increases the anti-slip properties of the fixing plate 340, further improving the stability of the device.

[0034] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
